    TECHNICAL FIELD [0002] The present invention relates to plastic containers for holding a commodity and, more particularly, a liquid commodity, whereby the plastic container has a side structure and a base structure collectively operable for create significant absorption of vacuum pressures without unwanted deformation in the other parts of the container or without increasing weight. BACKGROUND AND SUMMARY [0003] This section provides information on the repeating background 870190100037, from 10/07/2019, p. 3/46
    2/34 related to the present invention, which are not necessarily the prior art. This section also provides a general summary of the invention, and is not a comprehensive description of its scope or all of its characteristics.
    [0004] As a result of the environment and other interests, plastic containers, more specifically polyester and even more specifically polyethylene terephthalate (PET) containers, are now being used more than ever to pack numerous goods previously packed in glass containers. Manufacturers and professionals who fill the containers, as well as consumers, have recognized that PET containers are light, economical, recyclable and can be manufactured on a large scale.
    [0005] Currently, manufacturers supply PET containers for various liquid goods, such as juice and isotonic drinks. Suppliers often fill containers with these liquid products while the liquid product is at an elevated temperature, typically between 68 ° C - 96 ° C (155 ° F - 205 ° F) and generally approximately 85 ° C (185 ° F). When packaged in this way, the high temperature of the liquid goods sterilizes the container at the time of filling. The bottling industry refers to this process as hot filling, and containers designed to support the process like containers for hot filling or hot setting.
    [0006] The hot filling process is acceptable for goods that have a high acid content, but in general it is not acceptable for goods with a low acid content. However, manufacturers and professionals who supply containers with low-acid goods also want to make their goods available in PET containers.
    [0007] For goods with low acid content, pasteurizationPetition 870190100037, of 10/07/2019, p. 4/46
    3/34 tion and retorting are preferred sterilization processes. Both pasteurization and retort present a huge challenge for manufacturers of PET containers due to the fact that hot-set containers cannot withstand the temperature and time demands required by pasteurization and retort.
    [0008] Both pasteurization and retort are processes for cooking or sterilizing the contents of a container after filling. Both processes include heating the contents of the container to a specified temperature, usually approximately above 70 ° C (from approximately 155 ° F), for a specified period of time (20 - 60 minutes). Retort differs from pasteurization in that the retort uses higher temperatures to sterilize the container and cook its contents. The retort also applies high air pressure externally to the container to counter pressure inside the container. The pressure applied to the container externally is necessary because a bathtub with hot water is often used and the overpressure keeps the water, as well as the liquid in the contents of the container, in liquid form, above its respective boiling point temperatures.
    [0009] PET is a crystallizable polymer, which means that it is available in an amorphous form or in a semi-crystalline form. The ability of a PET container to maintain the integrity of its material refers to the percentage of the PET container in crystalline form, also known as the crystallinity of the PET container. The following equation defines the percentage of crystallinity as a fraction of volume:
    % Crystallinity = ~ X 100
    Pc ~ Pa [00010] where p is a density of the PET material; p a is a density of the amorphous and pure PET material (1,333 g / cm 3 ); ep c is a
    Petition 870190100037, of 10/07/2019, p. 5/46
    4/34 density of crystalline and pure material (1,455 g / cm 3 ).
    [00011] Container manufacturers use mechanical processing and thermal processing to increase the crystallinity of a container's PET polymer. Mechanical processing involves orienting the amorphous material to achieve stress hardening. This processing commonly involves stretching a PET preform along a longitudinal geometry axis and expanding the PET preform along a transverse or radial geometry axis to form a PET container. This combination promotes what manufacturers define as biaxial orientation of the molecular structure of the container. Manufacturers of PET containers currently use mechanical processing to produce PET containers, which have approximately 20% crystallinity on the side of the container.
    [00012] Thermal processing involves heating the material (be it amorphous or semi-crystalline) to promote crystal growth. In amorphous material, the thermal processing of the PET material results in a spherulite morphology that interferes with light transmission. In other words, the resulting crystalline material is opaque and, therefore, generally undesirable. However, when used after mechanical processing, thermal processing results in higher crystallinity and excellent clarity for those parts of the container that have biaxial molecular orientation. Thermal processing of a oriented PET container, which is known as a heat setting, typically includes blowing a PET preform against a mold heated to a temperature of approximately 120 ° C - 130 ° C (approximately 248 ° F - 266 ° F), and hold the blown container against the heated mold for approximately three (3) seconds. Manufacturers of PET juice bottles, which must have a hot filling of
    Petition 870190100037, of 10/07/2019, p. 6/46
    5/34 approximately 85 ° C (185 ° F), currently use the hot setting to produce PET bottles that have a total crystallinity in the range of approximately 25 - 35%.
    [00013] After being filled with heat, the hot-defined containers are capped and allowed to reside in general at a filling temperature for approximately five (5) minutes at which point the container, together with the product, is then cooled active before being transferred to labeling, packaging and transport operations. Cooling reduces the volume of liquid in the container. This phenomenon of product shrinkage results in the creation of a vacuum inside the container. In general, vacuum pressures within the container range from 1-300 mm Hg less than atmospheric pressure (ie 759 mm Hg - 460 mm Hg). If not controlled or otherwise accommodated, these vacuum pressures result in deformation of the container, which generates an aesthetically unacceptable or inappropriate container.
    [00014] In several examples, the weight of the container is correlated with the amount of the final vacuum present in the container after this filling, closing and cooling procedure, that is, the container is made relatively heavy to accommodate the forces related to the vacuum. Similarly, reducing the weight of the container, that is, producing a lightweight container, together with providing significant cost savings from the material point of view, requires a reduction in the amount of the final vacuum. Typically, the amount of final vacuum can be reduced through various processing options such as the use of nitrogen metering technology, minimizing leftovers in the container neck or reducing the filling temperature. However, a disadvantage in the use of technology with nitrogen dosing so that the maximum speeds of the production line advance in a compatible manner 870190100037, of 10/07/2019, p. 7/46
    6/34 current technology is limited to about 200 containers per minute. Such lower production line speeds are rarely acceptable. In addition, the dosage consistency is not yet at a technological level to achieve efficient operations. Minimizing the surplus in the container neck requires more processing during filling, again resulting in lower production line speeds. Reducing the filling temperature is also disadvantageous as this limits the type of goods suitable for the container.
    [00015] Typically, container manufacturers accommodate vacuum pressures by incorporating structures on the side of the container. Container manufacturers generally refer to these structures as vacuum panels. Traditionally, these paneled areas have a semi-rigid design, unable to accommodate the high levels of currently generated vacuum pressures, particularly in lightweight containers.
    [00016] The development of technology options to achieve an ideal balance of lightness and model flexibility is of great interest. In accordance with the principles of the present invention, an alternative vacuum-absorbing capacity is provided both within the body and the base of the container. Traditional hot-fill containers accommodate almost all vacuum forces within the body (or the side) of the container by deflecting the vacuum panels. Such containers are typically provided with a rigid base structure that substantially avoids deflection of the same and therefore tends to be heavier than the rest of the container.
    [00017] On the other hand, POWERFLEX technology, offered through the specification of the present patent application, uses a light-based model that accommodates almost all vacuum forces. EntrePetição 870190100037, of 10/07/2019, p. 8/46
    7/34 so, in order to accommodate this large amount of vacuum, the POWERFLEX base must be designed to invert, which requires enormous pressure, from an initial shape curved out to a final shape curved inward. This typically requires that the side of the container be rigid enough to allow the base to be activated under vacuum, thereby requiring more weight and / or structure within the side of the container. Neither traditional technology nor the POWERFLEX system offers the ideal balance for a thin and light container body and for the base that is able to withstand the necessary vacuum pressures.
    [00018] Therefore, an objective of the present invention is to achieve the ideal balance of weight and vacuum performance of both the container body and the base. To achieve this purpose, in some embodiments, a container for hot filling is provided, which comprises a model with a light and flexible base, which is easily movable to accommodate the vacuum, but which does not require an inversion or excessive pressure, thereby eliminating the need for a heavy side. The model with a light and flexible base serves to complement the vacuum absorption capacity inside the side of the container. In addition, an objective of the present invention is to define the theoretical limits of light weighing and to explore alternative vacuum absorption technologies that create an additional structure under vacuum.
    [00019] The body and base of the container of the present invention can be lightweight structures designed to accommodate vacuum forces either simultaneously or in sequence. In any event, the goal is for both the body and the base of the container to absorb a significant percentage of the vacuum. The use of a light-based model to absorb part of the vacuum forces allows for a total calculation of the light, flexibility of the model and
    Petition 870190100037, of 10/07/2019, p. 9/46
    8/34 an effective use of alternative vacuum absorption capacities on the side of the container. Therefore, it is an object of the present invention to provide such a container. However, it should be understood that in some embodiments, some principles of the present invention, such as the base configurations, can be used separately from other principles, such as the side configurations, or vice versa.

DETAILED DESCRIPTION [00055] The exemplary modalities will now be described in more detail with reference to the attached drawings. Exemplary modalities are provided so that this description is complete and fully transmits the scope to those skilled in the art. Various specific details are described such as examples of specific components, devices and methods to provide a complete understanding of the modalities of the present invention. It will be apparent to those skilled in the art that specific details do not need to be employed, that exemplary modalities can be incorporated in several different forms and that none of them should be created to limit the scope of the invention.
    [00056] The terminology used here is only intended to describe particular exemplary modalities and is not intended to be limiting. As used here, the singular forms one, one, o and a may also include the plural forms, unless the context clearly indicates otherwise. The terms understands, understands, includes, and owns, are inclusive and, therefore, specify the presence of attested characteristics, whole parts, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more characteristics, whole parts, steps, operations, elements, components, and / or groups thereof. The steps, processes and methodological operations described here do not necessarily have to be constructed as their performance requires in the particular order discussed or illustrated, unless specifically identified as a performance order. It should also be understood that additional or alternative steps can be employed.

    12/34 when cooling the contents in a hot-defined container, the containers generally have a series of vacuum panels or supports around their side. Traditionally, these vacuum panels are semi-rigid and unable to prevent unwanted distortion elsewhere in the container, particularly in light weight containers. However, in some containers with fewer vacuum panels, a combination of controlled deformation (i.e., base or closure) and vacuum resistance in the rest of the container is required. As described here, each of the above examples (ie, the traditional vacuum-absorbing container that has a light, flexible side with a rigid and heavy base, and the POWERFLEX container with a light and flexible base with a stiff, heavy side) may not completely enhance a hot fill container model. In addition, simply combining a side of the traditional vacuum-absorbing container and the base of the POWERFLEX container would typically generate a container having a side portion that would not be rigid enough to withstand pressure from an initial curved outward shape to a initial shape curved inward.
    [00058] Consequently, the present invention provides a plastic container, which allows its base part, under typical conditions of the hot filling process, to deform and move easily while maintaining a rigid structure (i.e. , against the internal vacuum) in the rest of the container. As an example, in a 500 ml (16 fl. Oz.) Plastic container, the container should typically accommodate about 18-24 cm 3 of volume displacement. In the present plastic container, the base part accommodates most of this requirement. The remaining parts of the plastic container are easily capable of accommodating the rest of that displacement 870190100037, from 10/07/2019, p. 14/46
    13/34 volume increase without a noticeable distortion. More particularly, traditional containers use a combination of the geometry and thickness of the sides of the bottle to create a structure that can withstand part of the vacuum, and movable side panels, folding supports, or movable bases to absorb the remaining vacuum. This results in two elements of internal vacuum-residual and absorbed. The sum of the residual vacuum and the absorbed vacuum equals the total amount of vacuum that results from the combination of a liquid commodity and its remains, contracted during cooling in a rigid container.
    [00059] Although alternative models are available in the art, which includes those that require the use of devices with external activation on the filling line (as in the Graham ATP technology), the present invention is capable of achieving lighter, hot-molded containers, without the need for an externally activated device, absorbing a higher percentage of the internal vacuum and / or volume in a controlled manner while providing sufficient structural integrity to maintain the desired bottle shape.
    [00060] In some embodiments, the container according to the present invention combines the side vacuum and / or the volume compensation panels or foldable supports with a flexible base model resulting in a mixture of previous technologies generating a container with lighter weight than could be achieved individually with one of two methods.
    [00061] The characteristics of vacuum and / or volume compensation could be defined as:
    X = the percentage of the total vacuum and / or the volume that is absorbed by the side panels, the supports and / or other vacuum and / or volume compensation characteristics;
    Petition 870190100037, of 10/07/2019, p. 15/46
    14/34
    Y = the percentage of the total vacuum and / or the volume that is absorbed by the movement of the base; and
    Z = the residual vacuum and / or volume remaining in the container after compensation is achieved by the vacuum and / or volume compensation characteristics on the side and / or base.
    [00062] In the case of traditional vacuum compensation characteristics (ie, only the side or just the base), the vacuum and / or volume compensation could be expressed as:
    Z = 10 to 90% of the total vacuum and / or volume; and X or Y = 10 to 90% of the total vacuum and / or volume.
    [00063] It should be understood from the previous description that a conventional container could merely reach a total of 90% of the total vacuum and / or the volume.
    [00064] However, according to the present invention, a container that can be filled with heat is provided where the vacuum and / or volume compensation could be described as:
    Z = 0 to 25% of the total vacuum and / or volume;
    X = 10 to 90% of the total vacuum and / or volume; and
    Y = 10 to 90% of the total vacuum and / or volume.
    [00065] As can be seen, according to these principles, the present invention is operable to achieve vacuum absorption both at the base and on the side, thus allowing, if desired, the absorption of the entire internal vacuum. It should be understood that in some embodiments, a little remaining vacuum may be desired.
    [00066] To create the container with the lowest possible weight in relation to the vacuum, the residual vacuum (Z) must be as close as possible to 0% of the total vacuum and the combined movements of the vacuum absorption characteristics must be designed to
    Petition 870190100037, of 10/07/2019, p. 16/46
    15/34 basically absorb 100% of the volume contraction that occurs inside the container as the content cools from the filling temperature to the point of maximum density under the required service conditions. At this external point, forces such as the upper load or the side load would result in a pressurization of the container, which would help it to resist these external forces. This would result in a container weight that is dictated by the requirements of the handling and distribution system, and not by the filling conditions.
    [00067] In some embodiments, the present invention provides a significantly round plastic container that does not oval below 5% of the total vacuum absorption consisting of a movable base and a movable side part with an average wall thickness less than 0.508 mm (0.020). However, in some embodiments, the present invention can provide a plastic container that comprises a base that absorbs between 10 and 90% of the total vacuum together with a side part that absorbs between 90 and 10% of the total vacuum absorbed. In some modes, the base and the side can be activated simultaneously. However, in some modalities, the base and the side can be activated sequentially.
    [00068] In addition, in accordance with the present invention, a significantly round plastic container is provided which provides a movable base and a movable side part which are activated simultaneously or sequentially at a lower vacuum level than 5% of the total vacuum absorption of the container.
    [00069] In a container with less vacuum panel, a combination of controlled deformation (ie, in a base or closure) and vacuum resistance in the rest of the container is required. Consequently, the present invention provides a plastic container which allows its base part under typical conditions

    16/34 of the hot filling process deforms and moves easily while maintaining a rigid structure (that is, against the internal vacuum) in the rest of the container.
    [00070] As shown in figures 1 and 2, a plastic container of the invention includes a finish 12, a neck or elongated neck 14, a support region 16, a body part 18, and a base 20. Those skilled in the art understand that the neck 14 can have an extremely short height, that is, it can become a short extension from the finish 12, or an elongated neck as illustrated in the figures, which extends between the finish 12 and the support region 16 The plastic container 10 is designed to hold a commodity during a thermal process, typically a hot-fill process. For hot-fill bottling applications, bottling plants generally supply container 10 with a liquid or product at an elevated temperature between approximately 68 ° C to approximately 96 ° C (155 ° F and 205 ° F ) and seal container 10 with a lid 28 before cooling. As the sealed container 10 cools, a little vacuum or negative pressure forms on the inside causing the container 10, in particular, the base 20 to change shape. In addition, the plastic container 10 can be suitable for other high temperature pasteurization processes or for filling and retorting, or also for other thermal processes.
    [00071] The plastic container 10 of the present invention is a blow molded and biaxially oriented container, with a unitary construction from a single layer or multiple layers material. A well-known process of stretching modeling, hot setting to fill the hot-filled plastic container 10 generally involves making a preform (not shown) of a polyester material,
    Petition 870190100037, of 10/07/2019, p. 18/46
    17/34 such as polyethylene terephthalate (PET), which has a shape, well known to those skilled in the art, similar to a test tube and in general with a cylindrical cross section and a length typically of approximately fifty per cent. cent (50%) of the height of the container. A machine (not shown) places the heated preform at a temperature between approximately 88 ° C and 121 ° C, approximately (190 ° F and 250 ° F) inside a mold cavity (not shown) that has a shape similar to the container plastic 10, The mold cavity is heated to a temperature between approximately 121 ° C and approximately 177 ° C (250 ° F and 350 ° F). An apparatus with a stretching rod (not shown) stretches or extends the heated preform within the mold cavity to a length of approximately equal to that of the container, thus molecularly orienting the polyester material in an axial direction that generally corresponds to a geometric and longitudinal central axis 50, While the stretching rod extends the preform, the air that has a pressure between 2.07 MPa to 4.14 MPa (300 PSI and 600 PSI) helps as it extends to preform in the axial direction and the expansion of the preform in a circumferential or arched direction thereby substantially forming the polyester material in the shape of the mold cavity and still molecularly orienting the polyester material in a direction generally perpendicular to the direction axial, thereby establishing the biaxial molecular orientation of the polyester material in most of the container. Typically, the material within the finish 12 and a subpart of the base 20 are not substantially molecularly oriented. The pressurized air retains most of the biaxial polyester material molecularly oriented against the mold cavity for a period of approximately two (2) to five (5) seconds before removal of the container from the mold cavity. To achieve the appropriate distribution of
    Petition 870190100037, of 10/07/2019, p. 19/46
    18/34 material within the base 20, the inventors employ an additional stretch molding step substantially as taught by U.S. Patent No. 6,277,321 which is incorporated herein by reference.
    [00072] Alternatively, other manufacturing methods using other conventional materials including, for example, polyethylene, high density polypropylene, polyethylene naphthalene (PEN), a mixture of PET / PEN or copolymer, and various structures with multiple layers may be suitable for the manufacture of the plastic container 10. Those skilled in the art will readily know and understand the method alternatives for the manufacture of the plastic container 10.
    [00073] The finish 12 of the plastic container 10 includes a part defining an opening or a mouth 22, a region with thread 24, and a support ring 26. Opening 22 allows the plastic container 10 to receive a commodity while the region with thread 24 provides a means for fixing similarly the closure or the screw cap 28 (shown in figure 2). Alternatives may include other suitable devices that fit the finish 12 of the plastic container 10. Consequently, the closure or lid 28 fits into the finish 12 to preferably provide an airtight seal of the plastic container 10. The closure or cover 28 is made of preferred way of a plastic or metallic material conventional in the closing industry and suitable for subsequent thermal processing, which includes pasteurization and high temperature retort. The support ring 26 can be used to guide or orient the preform (the precursor to the plastic container 10) (not shown) through various stages of manufacture. For example, the preform can be guided by the support ring 26, the support ring 26 can be used to assist in positioning the prePetition 870190100037, from 10/07/2019, pg. 20/46
    19/34 form in the mold, or a final consumer can use the support ring 26 to drive the plastic container 10, once manufactured.
    [00074] The elongated neck 14 of the plastic container 10 partly allows the plastic container 10 to accommodate the volume requirements. Integrally formed with the elongated neck 14 and extending downwards is the support region 16. The support region 16 merges inward and provides a transition between the elongated neck 14 and the body part 18. The body part 18 extends downwardly from the support region 16 to the base 20 and includes side parts 30. The specific construction of the base 20 of the container 10 allows the side parts 30 for the hot-defined container 10 not necessarily require additional panels of vacuum or tweezers and therefore it can be generally soft or made of glass. However, a significantly lightweight container will likely include side parts that have vacuum panels, ribs, and / or tweezers along with the base 20.
    [00075] The base 20 of the plastic container 10, which extends inwardly from the body part 18, can comprise a chime 32, a contact ring 34 and a central part 36. In some embodiments, the contact ring 34 is therefore that part of the base 20 that comes into contact with a support surface 38 which in turn supports the container 10. As such, the contact ring 34 can be a flat surface or a contact line that generally limits continuously or intermittently the base 20. The base 20 works to close the bottom part of the plastic container 10 and, together with the elongated neck 14, the support region 16, and the body part 18, to retain the goods.
    [00076] In some embodiments, the plastic container 10 is preferably hot defined according to the process mentioned above or with other conventional hot definition processes. In some embodiments, accommodating vacuum forces and
    Petition 870190100037, of 10/07/2019, p. 21/46
    20/34 while allowing the omission of the vacuum panels and clamps on the body part 18 of the container 10, of the base 20 of the present invention adopts an innovative and unprecedented construction. In general, the central part 36 of the base 20 can comprise a central handle 40 and an inversion ring 42. The inversion ring 42 can include an upper part 54 and a lower part 58. In addition, the base 20 can include a wall or circumferential edge extending upwards 44 and forming a transition between the inversion ring 42 and the contact ring 34.
    [00077] As shown in the figures, the central handle 40, when viewed in cross section, is generally in the form of a truncated cone that has an upper surface 46 which is generally parallel to the support surface 38. The lateral surfaces 48, which are generally flat, in cross section, and lean upwards towards the central geometric and longitudinal axis 50 of the container
    10. The exact shape of the center handle 40 can vary dramatically depending on various model criteria. However, in general, the total diameter of the central handle 40 (that is, the truncated cone) is at most 30% of the total diameter of the base 20. The central handle 40 is generally where the entrance of the preform is captured in the mold . Located within the upper surface 46 is the subpart of the base 20 which includes polymer material which is not substantially molecularly oriented.
    [00078] In some embodiments as shown in figures 3, 5, 7, 10, 13 and 16, when initially formed, the inversion ring 42 which has a gradual radius that surrounds and completely limits the central handle 40. When formed, the inversion ring 42 can project outward, below a plane where the base 20 would reside if it were flat. The transition between the central handle 40 and the adjacent inversion ring 42 can be quick in order to promote the maximum of
    Petition 870190100037, of 10/07/2019, p. 22/46
    21/34 orientation as close to the central handle 40 as possible. In principle, this serves to guarantee the minimum wall thickness 66 for the inversion ring 42, in particular at the bottom 58 of the base 20. In some embodiments, the wall thickness 66 of the bottom 58 of the inversion ring 42 is approximately between 0.20 mm (0.008 inch) and approximately 0.64 mm (0.025 inch), and preferably from 0.25 mm to 0.36 mm approximately between (0.010 inch to approximately 0.014 inch) for a container that has , for example, a base with a diameter of approximately 67.06 mm (2.6 inches). The wall thickness 70 of the upper surface 46, depending on precisely where a person performs the calculation, can be 1.52 mm or more (0.060 inch); however, the wall thickness 70 of the upper surface 46 transits rapidly to the wall thickness 66 of the lower part 58 of the inversion ring 42. The wall thickness 66 of the inversion ring 42 must be relatively consistent and thin enough to allow the inversion ring 42 is flexible and works properly. At a point along its circumferential shape, the inversion ring 42 can alternatively characterize a small dentition, not illustrated, but well known in the art, suitable for receiving a tongue that facilitates the rotation of the container around the central axis geometric and longitudinal 50 during a labeling operation.
    [00079] The wall or circumferential border 44, which defines the transition between the contact ring 34 and the inversion ring 42 can be, in cross section, a straight wall that extends upwards substantially of approximately 0.76 mm (0.030 inch) to approximately 8.26 mm (0.325 inch) in length. Preferably for a container base with a diameter of 67.06 mm (2.64 inches), the circumferential wall 44 can measure from 3.56 mm to 3.68 mm between approximately (0.140 inches) and approximates Petition 870190100037, from 07 / 10/2019, p. 23/46
    22/34 (0.145 inch) in length. For a 127 mm (5 inch) diameter base, the circumferential wall 44 could be as wide as 8.26 mm (0.325 inch) in length. The circumferential wall or border 44 can generally be at an angle 64 with respect to the central geometric and longitudinal axis 50 between approximately zero degrees and approximately 20 degrees, and preferably approximately 15 degrees. Consequently, the circumferential wall or edge 44 need not be exactly parallel to the geometric and longitudinal central axis 50, the circumferential wall or edge 44 is a distinctly dentable structure between the contact ring 34 and the inversion ring 42. The circumferential wall or border 44 provides resistance for the transition between the contact ring 34 and the inversion ring 42. In some embodiments, this transition must be abrupt in order to maximize the local resistance, as well as to form a geometrically rigid structure . The resulting localized resistance increases the wrinkle resistance at the base 20. The contact ring 34, for a base of the container with a diameter of 67.06 mm (2.64 inches), can have a wall thickness 68 of 0.25 mm to 0.41 mm (from approximately 0.010 inch to approximately 0.016 inch). In some embodiments, the wall thickness 68 is at least the same and more preferably it is approximately ten percent, or more, of the wall thickness 66 of the bottom 58 of the inversion ring 42.
    [00080] When initially formed, the central handle 40 and the inversion ring 42 remain as described above and shown in figures 1, 3, 5, 7, 10, 13 and 16. Consequently, when molded, a dimension 52 calculated between the upper part 54 of the inversion ring 42 and the support surface 38 is greater than or equal to a dimension 56 calculated between the lower part 58 of the inversion ring 42 and the support surface 38. During filling, the central part 36
    Petition 870190100037, of 10/07/2019, p. 24/46
    23/34 of the base 20 and the inversion ring 42 will sag slightly or deviate downwards towards the support surface 38 under the temperature and weight of the product. As a consequence, dimension 56 becomes almost zero, that is, the lower part 58 of the inversion ring 42 is practically in contact with the support surface 38. During filling, closing, sealing and cooling of the container 10 , as shown in figures 2, 4, 6, 8, 12, 14 and 17, the vacuum-related forces cause the central handle 40 and the inversion ring 42 to rise or be pushed upwards thereby displacing volume. In this position, the central handle 40 generally retains its truncated cone shape in cross section with the upper surface 46 of the central handle 40 remaining substantially parallel to the support surface 38. The inversion ring 42 is incorporated within the central part 36 of base 20 and virtually disappears, acquiring a more conical shape (see figures 8, 14 and 17). Consequently, during closing, sealing, and cooling of the container 10, the central part 36 of the base 20 exhibits a substantially tapered shape that has surfaces 60 in cross section that are generally flat and that incline upwards towards the axis geometric and longitudinal central 50 of container 10, as shown in figures 6, 8, 14 and 17. This conical shape and in general the flat surfaces 60 are defined in part by an angle 62 of approximately 7 ° to approximately 23 °, and more typically between approximately 10 ° and approximately 17 °, relative to a horizontal plane or the support surface 38. When the dimension value 52 increases and the dimension value 56 decreases, the potential displacement of the volume within the container 10 increases. In addition, while flat surfaces 60 are substantially straight (particularly as shown in figures 8 and 14), those skilled in the art will understand that flat surfaces 60 will have frePetition 870190100037, from 10/07/2019, pg. 25/46
    24/34 a wavy appearance. A typical 67.06 mm (2.64 inch) diameter base, container 10 with base 20, has a free space dimension of the base when molded 72, calculated from the top surface 46 to the support surface 38 , with a value of approximately 12.70 mm (0.500 inch) to approximately 15.24 mm (0.600 inch) (see figures 7, 13 and
    16). During response to vacuum-related forces, the base 20 has a free space dimension of the base when filled 74, calculated from the upper surface 46 to the support surface 38, with a value of approximately 16.51 mm (0.650 inches) ) up to approximately 22.86 mm (0.900 inch) (see figures 8, 14 and
    17). For smaller or larger containers, the value of the free space dimension of the base when molded 72 and the value of the free space dimension of the base when filled 74 can be proportionally different.
    [00081] As described above, the difference in wall thickness between the base 20 and the body part 18 of the container 10 is also important. The wall thickness of the body part 18 must be large enough to allow the inversion ring 42 to flex properly. Depending on the geometry of the base 20 and the amount of force required to allow the inversion ring 42 to flex properly, that is, ease of movement, the wall thickness of the body part 18 must be at least 15%, at average, greater than the wall thickness of the base 20. Preferably, the wall thickness of the body part 18 is two (2) to three (3) times greater than the wall thickness 66 of the bottom 58 of the inversion ring 42. A greater difference is required if the container is to withstand greater forces either from the force required to initially cause the inversion ring 42 to flex, or to accommodate the additional forces applied once the movement of the
    Petition 870190100037, of 10/07/2019, p. 26/46
    25/34 base 20 is completed.
    [00082] In some embodiments, the alternative hinges or hinge points described above may take the form of a series of notches, corrugations, or other characteristics that are operable to improve the response profile of the base 20 of the container
    10. Specifically, as shown in figures 28-30, in some embodiments the vacuum response profile of base 20 can define abrupt flexion responses that produce a discontinuous and segmented vacuum curve (see figure 29) that defines a pair of vertical sections 302, 304, indicative of the abruptly reduced internal vacuum pressure. Although this answer may be suitable for some modalities, in other modalities a more gradual and subtle vacuum curve may be desired (see figures 28 and 30 which will be discussed here). Therefore, a more gradual and subtle vacuum curve profile can provide the opportunity to reshape the side profile and / or vacuum panels to reduce the need for vacuum panels and / or to reduce material wall thickness over the side. Such an arrangement can provide a lightweight container and improved model possibilities.
    [00083] That is, as illustrated in figures 16-27, the inversion ring 42 can include a series of notches, undulations, or other characteristics 102 formed in and along the ring. As shown (see figures 16-20), in some modalities, the series of characteristics 102 generally have a circular shape. However, it should be understood that features 102 can define any of the numerous formats, configurations, arrangements, distributions and profiles.
    [00084] With particular reference to figures 16-27, in some embodiments, characteristics 102 are generally spaced equidistant from each other and arranged in a series of fileiPetição 870190100037, of 10/07/2019, p. 27/46
    26/34 ras and columns that completely cover the inversion ring 42. Similarly, the series of characteristics 102 can in general and completely surround and limit the central handle 40 (see figure
    18). It is also contemplated that the series of rows and columns of characteristics 102 can be continuous or intermittent. Features 102, when viewed in cross-section, can be shaped like a truncated or rounded cone that has an extremely inferior surface or point and side surfaces 104. Side surfaces 104 are generally flat and slope inward toward the geometric and longitudinal central axis 50 of the container 10. The exact shape of the features 102 can vary dramatically depending on various model criteria. Although the geometry described above features 102 is preferred, a person skilled in the art will readily understand that other geometric arrangements are similarly contemplated.
    [00085] With particular reference to figures 19 and 20, features 102 are illustrated according to a series similarly formatted of ripples spaced equidistantly from each other as a plurality of rows or radial columns extending from the central handle 40 about the inversion ring 42. Although they are illustrated being directed into the container 10, it should be understood that features 102 can be directed outwards in some embodiments. It should also be understood that the size, shape and the particular distribution of undulations can vary depending on the performance of the desired vacuum curve and provide control over the flexibility and basic movement under the vacuum that provide a smooth performance. As particularly illustrated in figure 28, it can be seen that under the vacuum pressure load, the base 20 and the container 10 that employ the base of figures 19 and 20, produce a vacuum curve in general subtle and
    Petition 870190100037, of 10/07/2019, p. 28/46
    27/34 consistent that defines a generally constant ramp.
    [00086] With particular reference to figures 21-23, features 102 are illustrated according to a series similarly shaped of undulations intersecting triangularly spaced equidistant from one another as a plurality of radial rows or columns extending from of the central handle 40 on the ring 42. The characteristics 102 of the present embodiment are directed inward and define limits in common with the adjacent characteristics 102 along the edges of the inverted triangle. It should also be understood that the particular size, shape and distribution of undulations can vary depending on the performance of the desired vacuum curve to provide control over the flexibility and basic motion under vacuum that provide smooth performance.
    [00087] With particular reference to figures 24 and 25, features 102 are illustrated as a spider web of radially extending folds 400, spaced equidistantly from each other extending from the central handle 40 over the ring 42. Folds 400 can be joined through a series of interconnected folds 402, such as arcuate folds that extend between adjacent folds 400 forming a series of concentric spaced circumferential rings that extend around handle 40. Also it should be understood that the particular size, shape and distribution of folds 400 and interconnected folds 402 may vary depending on the performance of the desired vacuum curve to provide control over the flexibility and basic movement under vacuum that provide smooth performance.
    [00088] With particular reference to figures 26 and 27, characteristics 102 are illustrated according to a series formatted in a similar way of folds extending 500 being spaced in a similar way
    Petition 870190100037, of 10/07/2019, p. 29/46
    28/34 equidistant from each other extending circumferentially from the central handle 40 over the inversion ring 42. Circumferential folds 500 can be joined through a series of interconnected folds extending radially 502 between the folds adjacent circumferential folds 500. The circumferential folds 500 and the radially extending interconnected folds 502 form a rotating brick model together. It should be noted that the radially extending interconnected folds 502 can extend continuously from handle 40, each as a single continuous fold, or can be staggered to form the brick pattern. It should also be understood that the size, shape and the particular distribution of the folds 500 and 502 can vary depending on the performance of the desired vacuum curve to provide control over the flexibility and basic movement under vacuum that provide smooth performance.
    [00089] As such, the base models, described above, cause movement and activation of the inversion ring 42 to start more easily by increasing at least the surface area of the base 20 and, in some embodiments, by decreasing the thickness of the material in these. areas. In addition, the hinges or alternative hinge points also cause the inversion ring 42 to rise or be pushed up more easily, thereby displacing more volume. Consequently, the hinges or alternative hinge points retain and enhance the start and degree of ease of response of the inversion ring 42 while improving the degree of volume displacement. Hinges or alternative hinge points provide a significant displacement of volume while improving the amount of vacuum-related forces required to cause movement of the inversion ring 42. Consequently, when container 10 includes
    Petition 870190100037, of 10/07/2019, p. 30/46
    29/34 the hinges or alternative hinge points described above, and when it is under vacuum-related forces, the inversion ring 42 initiates the movement more easily and the flat surfaces 60 can often reach an angle generally greater than 62 otherwise, thereby displacing a greater amount of volume.
    [00090] Although it is not always necessary, in some embodiments, the base 20 may comprise three grooves 80 substantially parallel to the side surfaces 48. As shown in figures 9 and 10, the grooves 80 are equally spaced around the central handle 40. The grooves 80 have a substantially semicircular configuration, in cross section, with surfaces that blend subtly with adjacent side surfaces 48. In general, for container 10 which has a base of 67.06 mm (2.64 inches) in diameter , the grooves 80 have a depth 82, relative to the side surfaces 48, of approximately 3.00 mm (0.118 inches), typical for containers that have a nominal capacity between 500 ml and 625 ml (16 fl. oz and 20 fl oz) The inventors predicted, as an alternative to more traditional approaches, that the central handle 40 with grooves 80 may be suitable to fit a retractable axle (not shown) ) to rotate the container 10 around the geometric and longitudinal central axis 50 during a label fixing process. Although the three (3) slots 80 are shown, and this is the preferred configuration, those skilled in the art will understand that another number of slots 80, i.e. 2, 4, 5, or 6, may be appropriate for some configurations container.
    [00091] When base 20, with a relative wall thickness ratio as described above, responds to vacuum-related forces, grooves 80 can help facilitate movement
    Petition 870190100037, of 10/07/2019, p. 31/46
    30/34 progressive and uniform inversion ring 42. Without the grooves 80, particularly if the wall thickness 66 is not uniform or consistent around the geometric and longitudinal central axis 50, the inversion ring 42, responding to forces related to the vacuum, it may not move uniformly, or it may move inconsistently, twisted, or unevenly. Consequently, with the grooves 80, the radial parts 84 are formed (at least initially during movement) within the inversion ring 42 and generally extend adjacent each groove 80 in a radial direction from the geometric and longitudinal central axis 50 (see figure 11) becoming, in cross section, a substantially straight surface that has an angle 62 (see figure 12). In other words, when someone views base 20 as shown in figure 11, the formation of radial parts 84 appears as valley-like dentitions within inversion ring 42. Consequently, a second part 86 of inversion ring 42 between any one from the two adjacent radial parts 84 it retains (at least initially during movement) an inverted shape partially rounded (see figure 12). In practice, the preferred embodiment illustrated in figures 9 and 10 often assumes the shape configuration illustrated in figures 11 and 12 as its shape configuration. However, with additional vacuum-related forces applied, the second part 86 eventually strengthens to form the generally tapered shape that has the flat surfaces 60 that slope towards the central geometric and longitudinal axis 50 at angle 62 similar to that shown in the figure 8. Again, those skilled in the art understand that flat surfaces 60 are likely to have a certain wavy appearance. The exact nature of the flat surfaces 60 will depend on a variety of other variants, for example, the specific wall thickness ratios within the
    Petition 870190100037, of 10/07/2019, p. 32/46
    31/34 base 20 and side parts 30, the specific proportions of the container 10 (i.e. diameter, height, capacity), the specific conditions of the hot filling process and others.
    [00092] The plastic container 10 can include one or more horizontal supports 602. As shown in figure 31, the horizontal supports 602 still include an upper wall 604 and a lower wall 606 separated by an inner curved wall 608. The inner curved wall 608 it is defined in part by an extremely internal and relatively closed radius n. In some embodiments, the extremely closed radius π resides within the range of about 0.254 mm to 0.762 mm (0.01 inch to about 0.03 inch). The extremely internal and relatively closed radius π of the inner curved wall 608 facilitates the improved material to flow during the blow molding of the plastic container 10 thereby allowing the formation of the relatively deep horizontal supports 602.
    [00093] Horizontal supports 602 still include an upper outer radius r2 and a lower outer radius r3 Preferably both the upper outer radius r2 and the lower outer radius r3 reside within the range of about 1,778 mm to 3,556 mm (0, 07 inch to about 0.14 inch). The upper outer radius r2 and the lower outer radius r3 may be the same or differ from each other. Preferably the sum of the upper outer radius r2 and the lower outer radius r3 will be equal to or greater than about 3.556 mm, 7.112 mm (0.14 inch and less than about 0.28 inch).
    [00094] As shown in figure 31, horizontal supports 602 still include an upper inner radius r4 and a lower inner radius r5, The upper inner radius r4 and the lower inner radius r5 reside within the range of about 2.032 mm to 2.794 mm ( 0.08 inch to about 0.11 inch). The upper inner radius r4 and the lower inner radius r5 may be the same or may differ from each other. Preferably
    Petition 870190100037, of 10/07/2019, p. 33/46
    32/34 the sum of the upper inner radius r4 and the lower inner radius r5 will be equal to or greater than about 4.064 mm to 5.588 mm (0.16 inch and less than about 0.22 inch).
    [00095] Horizontal supports 602 have an RD support depth of about 3.048 mm (0.12 inch) and an RW support width of about 5.588 mm (0.22 inch) when calculated from the upper extension of the outer radius upper r2 and the lower extension of the lower external radius r3 As such, horizontal supports 602 have a ratio of rib width RW to rib depth RD. The ratio of RW rib width to RD rib depth is, in some modalities, in the range of about
    1.6 to about 2.0.
    [00096] Horizontal supports 602 are designed to achieve optimum performance in relation to vacuum absorption, upper load resistance and dentition resistance. Horizontal supports 602 are designed to lightly compress in a vertical direction to accommodate and absorb the vacuum forces resulting from hot filling, closure content and container cooling. Horizontal supports 602 are also designed to compress when the filled container is exposed to forces with excessive overload.
    [00097] As shown in figure 31, the radii described above of the horizontal support 602, the walls, the depth and the width together form a support angle A. The support angle A of an unfilled plastic container 10 can be in around 58 degrees. After hot filling, the contents of the container closing and cooling, the resulting vacuum forces cause the support angle A to reduce by about 55 degrees. This represents a reduction of the support angle A of about 3 degrees as a consequence of the vacuum forces present inside the container. Petition 870190100037, from 10/07/2019, p. 34/46
    33/34 te plastic 10 which represent a reduction in the support angle A of about 5%. Preferably, the support angle A will be reduced by at least about 3% and not more than about 8% as a result of the vacuum forces.
    [00098] After filling, it is common for the plastic container 10 to be packed in bulk in pallets. The pallets are then stacked on top of each other resulting in higher loading forces being applied to the plastic container 10 during storage and distribution. In this way, the horizontal supports 602 are designed so that the support angle A can be further reduced to absorb the upper loading forces. However, horizontal supports 602 are designed so that the upper wall 604 and the lower wall 606 never come into contact with each other as a result of the vacuum or the upper loading forces. Instead, horizontal supports 602 are designed to allow the plastic container 10 to reach a state in which the plastic container 10 is supported in part from the inside of the product when exposed to excessive forces of upper load thereby preventing blades from permanent distortion of the plastic container 10. Furthermore, this allows horizontal supports 602 to re-establish their limits and return substantially to the same shape as before the upper loading forces were applied, once such upper loading forces are removed.
    [00099] The horizontal bases 610 are generally flat in vertical cross section when molded. When the plastic container 10 is subjected to vacuum and / or to the upper loading forces, the horizontal bases 610 are designed to slightly swell out, in vertical cross section, to assist the plastic container 10 in absorbing these forces in a uniform manner .
    [000100] It should be understood that the supports 602 may not be available. 870190100037, from 10/07/2019, p. 35/46
    34/34 are parallel to the base 20, as shown in figure 32. In other words, the supports 602 can be activated in or more directions around the periphery of the container 10 and the side 30 of the container 10. More specifically, the supports 602 can be arched so that the center of the supports 602 is arched upwards towards the neck 18. This can be the case for all the supports 602 in the container 10 when viewed from the same side of the container 10. However, the supports 602 can be arched in a different, opposite and downward direction, such as towards the bottom of the container 10. More specifically, the center of the supports 602 may be closer to the base 20 than to one side. In rotating the container 10 and following the supports 602 360 degrees around the container 10, the supports 602 can have two (2) equally high, the highest points and two (2) equally low, the lowest points.
    [000101] The preceding description of the modalities has been provided for the purpose of illustrating and describing. It is not intended to be exhaustive or to limit the invention. Individual elements or characteristics of a particular modality in general are not limited to that particular modality, however, where applicable, they are interchangeable and can be used in a selected modality, even if it has not been specifically shown or described. They can also be varied in several ways. Such variations should not be considered to be apart from the invention, and all such modifications must be included within the scope of the invention.
