    [001] The present invention relates to the end cap of a beverage container. More specifically, the present invention relates to a container lid, which comprises a first opening portion, and at least a secondary opening portion, to improve ventilation and improve the outflow of the product when its contents are poured.
    BACKGROUND OF THE INVENTION [002] Containers, and, more specifically, metal beverage containers, are typically manufactured by interconnecting an end cap of beverage containers to the neck of the beverage container body. In some applications, an end cap can be interconnected with both the upper and lower sides of the container body. Most often, however, the beverage container end cap that interconnects the top end of the beverage container body is laminated and rolled from a flat plate of blanket material, such as aluminum. It is generally known in the art to produce end caps for beverage containers, which use an opening device to selectively open a portion of end cap. For example, a handle for opening cans ("Stay on Tabs" (SOTs)) usually includes a nose portion, a tail portion, and a rivet, which interconnects the pull handle with the top surface of the end cap. The tail portion usually has a loop or tail, which must be pulled by the user, which moves the nose portion of the handle downwards, to initiate the opening of the container, shearing a marking line, which defines the primary opening of the Petition 870190035385, of 12/12/2019, p. 7/39
    2/27 of.
    [003] Conventional beverage container end caps with SOT pull handles generally have a reduced, inconsistent, irregular drink flow as the contents of the container are extracted, because these end caps have a single area of opening having a given size. Thus, conventional beverage container end caps are generally designed to pour the contents of the container, without considering the incoming air flow, necessary to compensate for the volume change, and to smoothly and steadily pour the beverage.
    [004] Several patents attempted to improve the condition of the beverage pouring through the end caps of beverage containers (cans), creating one or more openings, including US Patent No. 7,513,383 to Hwang and US No. 4,289,251 to Maliszewski, which are incorporated by reference in their entirety. Hwang describes a can opening device, having a first opening portion distinct from the second opening portion, so that the fluid flows more consistently from the can. Hwang, however, does not teach the various new components of the present invention, including a secondary opening portion, which can be selectively opened to complement or facilitate the flow rate, through the primary opening portion, by rotating the handle to the preferred orientation . Maliszewski describes a container end cap with a first marking line that defines a first movable panel portion and a second marking line that defines a second movable panel portion. Maliszewski, however, does not teach the various new components of the present invention, including a secondary opening portion, which can be selectively opened to complement or facilitate the flow through the primary opening portion.

    3/27 [005] The following description describes an improved container end cap, adapted to interconnect a container body, and which has a first opening portion, a rotatable handle, and at least one additional vent opening, for selectively facilitate the flow of content from the container.
    SUMMARY OF THE INVENTION [006] Based on the limitations of the end caps discussed above, there is an unmet need for an end cap having a pull handle and at least an optional opening area, to facilitate the supply of the contents of the container. There is additionally an unmet and felt need to provide such a device where an additional opening area selectively activated and opened based on user preference and using the same mechanisms as the pull handle mounted on the end cap. The following description generally describes a metal end cap having a pull handle and a plurality of opening areas, which employ a long-felt combination of components that meets this need.
    [007] In one aspect of the present invention, a container end cap is provided with a primary opening portion, and at least a secondary opening portion, which can be selectively opened by a user, to create a better flow characteristic. , due to the larger open area and / or an area that allows air to enter the body of the container through one or more ventilation openings, while the content flows through another opening.
    [008] In various embodiments, the container end caps of the present invention are adapted to connect a neck of a container body. More specifically, the end cap generally includes a peripheral rim to provide a double seal to the neck of the container, a wall that descends from the back.

    4/27 peripheral edge, a countersink comprising an outer panel wall, and an inner panel wall, and a central panel extending into an inner panel wall. For the purposes of further supporting and allowing the present invention, US Patent No. 7,506,779 to Jentzsh etal, called Method and Apparatus for Forming a Reinforcing Engraving in a Container End Closure ”, and US No. 7,100,789 by Nguyen etal , called “Mettalic Beverage Can End With Improved Chuck Wall and Counterrsink” are incorporated by reference in their entirety.
    [009] Another aspect of the present invention provides an end cap and primary opening, where a handle interconnects a central panel unit, a rivet for rotatingly fixing the handle on the end cap, a secondary marking line, which defines an area secondary opening, and a transition zone between the primary opening and the secondary opening. In one embodiment, the first opening area and the second opening area are positioned adjacent, and the transition zone prevents the opening of the secondary opening area when the handle is used to open the first opening area. For example, in one embodiment, the transition zone inhibits the propagation of a primary marker line to a secondary marker line or opening area. Alternatively, the first opening area and the second opening area are not positioned adjacent, but rather are spaced apart in different locations.
    [0010] Another aspect of the present invention provides a rotatable handle capable of opening a defined passage in a first opening area, by means of a first movement of the handle, that is, lifting the handle, and subsequently rotating the handle, to open a secondary opening area, by means of a second opening movement.

    Thus, a user can selectively determine whether to use the secondary opening to provide ventilation, or, instead, drink from the container in the conventional manner, through the primary opening, without the increased flow of ventilation.
    [0011] Another aspect of the present invention provides a handle with one or more components, which limit or in some way define the desirable or necessary extent of rotation to position the handle to open one or more opening areas of a control panel. For example, components of the present invention may include recesses or indentations in the handle and corresponding projections or obstacles in the center panel, which prevent the rotation of the handle around a rivet, in addition to a predetermined orientation. In an alternative embodiment, a portion of the central panel of the present invention is adapted to receive a handle, and thus to limit the extent of rotation of the handle from an initial position. In an alternative embodiment, the handle on a central end cap panel is rotatable between an angle of 0 o (with respect to the initial position) and ± 90 °. In an alternative embodiment, the handle is rotatable about a geometric axis substantially parallel to a horizontal plane of a central panel, between an angle of 0 o (with respect to the initial position) and ± 45 °.
    [0012] In another embodiment, an end cap is provided having at least a first opening portion and a secondary opening portion, where the first opening portion and the secondary opening portion can be opened without having to rotate the handle . For example, in one embodiment, the present invention comprises a first opening area defined by a marking line and a passage, the marking line is adapted to be cut, and the passage is opened by turning the handle. The second opening area is defined by a secondary marking line and a transition zone, the transition zone prevents the spread of a marking line

    6/27 primary and requires the user to apply an additional or distinct force (compared to the force applied to open the primary opening portion) to open the secondary opening portion. Thus, in one embodiment, a first opening portion and the second opening portion can be opened in series through the application of one or more forces, where the opening of the second opening portion is distinct from the first due, for example, to the zone transition. Thus, in one embodiment, a handle does not need to be rotated around the longitudinal geometric axis of the container body and end cap combination to break or open the secondary opening area.
    [0013] In one embodiment, an end cap adapted to connect the container body is provided. The metal end cap comprises a substantially flat center panel, and a means of applying force to apply a force directed into the center panel. The means of applying force may include, for example only, a handle having a loop or tail portion and nose portion, where the handle is connected to an end cap with a rivet.
    [0014] In alternative embodiments, an end cap does not comprise a handle portion, as seen in several SOT-type pull handles. Instead, in certain embodiments, an end cap is provided with a primary opening area / portion, and at least one secondary selective opening area / portion, where said first opening area and said second opening area are marked or broken from the panel with an additional tool. Additional tools comprise but are not limited to can openers known in the art, and similar devices adapted to open or shear a central panel. In one embodiment, a means of applying force may be provided, which comprises a tool or object, not attached or attached to the cover. For example, opened
    Petition 870190035385, of 12/12/2019, p. 12/39
    7/27 known bottle resins (“Church Key” type) and similar devices, suitable for applying force to the end cap.
    [0015] In one embodiment, a pivot means is permanently mounted on said central panel, to pivotally mount the means of applying force on the central panel. The pivot means may include, for example, a rivet affixed to a portion of the central panel and a receiving portion of a rivet island or similar rivet arranged on the handle. Thus, in various embodiments, pivot means are provided to allow the handle to rotate about its geometric axis, parallel to the longitudinal geometric axis of the container / end cap combination, and still generally preventing an inadvertent displacement of the handle from a central panel. A rotational limiting means can be provided in the end cap adapted to limit the extent of rotation of the force applying means. The rotational limiting means of the present invention includes, but is not limited to obstacles, projections, recessions, and various other types of components, formed or placed in a central panel, adapted to contact a handle and / or provide a visual indication of the desired orientation the handle.
    [0016] A first opening portion having a breakable marking line is provided in one embodiment, the breakable marking line defines a first opening portion and a first hinge portion integrated with the central panel. In one embodiment the second opening portion is provided which comprises a breakable marking line defining the second opening portion and a second hinge portion integrated with the central panel, and a transition portion that substantially prevents the fracture propagation of said line breakable marking line from said first opening portion to said breakable marking line from said second opening portion
    Petition 870190035385, of 12/12/2019, p. 13/39
    [0017] Another aspect of the present invention provides a method of opening a container, that is, improving the condition of pouring a drink from a container, including not being limited to a method comprising the steps of opening an area of primary opening, where the force application means is rotated to apply a first downward force on a first opening portion to break a first breakable marking line. Subsequently, the force application means (i.e. pull handle), at least partially, is restored, from its first initial position, and the force application means is rotated, so that a middle nose portion force application device is positioned over a portion of the second opening portion, and the force application means is rotated to apply a second downward force to a second opening portion, to break a second marking line. In alternative embodiments, a third opening can be formed, to be broken through an additional rotation of the pull handle. In alternative embodiments, similar steps can be repeated to open one or more ventilation portions in the end cap.

In certain cases, details that are not necessary to provide a full understanding of the invention, or that make it difficult to understand other details, may be omitted from the drawings. In addition, it should be understood that the present invention is not limited to the particular embodiments illustrated in the drawings. DETAILED DESCRIPTION [0034] Various embodiments of the present invention will be described
    Petition 870190035385, of 12/12/2019, p. 17/39
    12/27 here and represented in the drawings. It should be expressly understood that although figures 1 to 8 represent a metal end cap including a pull handle and at least one secondary ventilation opening, the present invention is not limited to this embodiment.
    [0035] Referring now to figure 1, a top plan view of a metal end cap according to an embodiment is shown, in which a first opening portion is in a first closed position. An end cap adapted to interconnect a container body is shown, where the end cap comprises a panel 14 with a primary opening area 28 and a secondary opening area 32. In one embodiment, an opening area 28 comprises a first passage 26 which is defined by a primary line 30, when the primary opening area 28 is in a first closed position. A primary opening area 28 of the present invention comprises, for example, portions of material capable of being at least partially separated and retained by the remainder of the central panel. The primary opening area 28 is at least initially separated from the secondary opening area 32 and secondary passage 27, by a primary opening hinge 46. The primary opening hinge 46 facilitates selective opening of the primary opening area 28 by a nose of the pull handle or by means of applying force, without simultaneously opening a secondary opening area 32. The means of applying force of the present invention includes, but is not limited to, a handle 34, which comprises a nose portion 36 and rivet 42, in communication with a rivet island 40 and tail 36. When the tail 36 is pulled, the nose 35 moves downwards, shearing the line 30 and starting the opening.
    [0036] In one modality, secondary dialing 58 starts at
    Petition 870190035385, of 12/12/2019, p. 18/39
    13/27 end of a first transition zone (53 in figure 4B) and allows the propagation of fracture of the secondary marking termination component 62, thereby creating a ventilation component, when an appropriate force is applied to it. In various embodiments, secondary markings 58 of the present invention can be straight, or curved at various angles. Marking termination components 62 of the present invention are provided to generally define or limit the propagation of a secondary marking 58. In one embodiment, a secondary marking termination component 62 comprises a curved profile, to help prevent the propagation of a line and create a desired form of ventilation.
    [0037] Furthermore, the present invention contemplates a secondary marking joint 74. The secondary marking joint 74 is generally defined as a portion of the panel 14 disposed between the end of a secondary marking line and a point of the panel 14 close to the rivet 42. In one embodiment, the joint of the present invention is arranged in a position relative to the handle 34, so that the joint serves as a point of rotation for a portion of material, such as the bypass 27.
    [0038] In one embodiment, first and second joints 46, 74 are arranged on a central panel, in a region defined between approximately 0 o and 240 ° (ie 0 o corresponding to the center line of a handle, as shown in figure 1 ). Those skilled in the art should recognize that a secondary opening portion 32 can be arranged in a variety of positions either adjacent or not adjacent to the primary opening area 28, provided that it provides adequate space for the primary opening area 28.
    [0039] In general, a handle 34 is provided on the end cap 10, which is pivotally attached to the end cap 10 through
    Petition 870190035385, of 12/12/2019, p. 19/39
    14/27 of a “half pivot”. The pivot means may include, but is not limited to, a rivet 62, attached to a central panel 14, which engages a portion of the handle 34, such as a rivet island 40. In one embodiment, the pivot means allows the handle 34 rotate on the central panel 10. In various embodiments, the handle is generally oriented perpendicular to the longitudinal extension of the container, where the longitudinal extension of the container defines the center of rotation of the handle 34. As those skilled in the art should recognize, when a portion of the handle 34 of the present invention is raised and levered over a point generally defined by the location of the rivet 42, a downward opening force is applied to a passage 26 away from the panel 14 at the primary marking 30, which propagates around the marking 30, while an opening is formed, thus allowing to pour the contents of the container.
    [0040] The present invention, furthermore, contemplates a second opening area 32, generally defined by a secondary marking line 58, primary marking opening joint 46, and transition zone 54. In one embodiment, the opening opening joint primary marking 46 of the present invention is created by the initial fracture close to rivet 42, which spreads from primary marking 30 towards primary marking terminating component 50. When the fracture reaches primary marking terminating component 50, handle 34 it results approximately perpendicular to the panel 14, thus producing a force applied by the handle 34 over the passage 26 in a direction substantially perpendicular to the longitudinal geometric axis of a container. As those skilled in the art should recognize, the handle 34, in this position, generally curves the passage 26, opposite to the shear, fracture etc., subsequent to the passage 26. In addition, as will be described in detail later, a marking termination component secondary 50 is
    Petition 870190035385, of 12/12/2019, p. 20/39
    Provided 15/27, which dictates the general area in which the propagation of primary marking fracture ends.
    [0041] In one embodiment, a transition zone 54 is provided in the central panel 14. The transition zones 54 of the present invention generally comprise an area that inhibits fracture propagation, from a primary marking 30 to a secondary marking 58, and thus helping to prevent an inadvertent opening of a secondary opening area 32. For example, a transition zone 54 of the present invention can stop the propagation of the primary marking fracture 30 due to the residual depth of the marking, interference in the marking path (i.e. check groove), predetermined void distance between primary 30 and secondary 58, and / or various combinations, including, but not limited to, greater material thickness. In one embodiment, the secondary opening area 32 of the present invention is preferably positioned, so that the opening area 32 generally extends from the lateral midline of the central panel 14 (i.e. a line running laterally in the rivet 42, arranged in the center of a central panel 14, as shown in figure 1). Those skilled in the art should appreciate, however, that the location of the secondary opening area 32 can be changed and / or repositioned in a variety of locations.
    [0042] As those skilled in the art will understand, a secondary opening area 32 can be arranged on either side of the loop 34 of the present invention. In one embodiment, the present invention 10 contemplates a plurality of optional opening areas 32, in addition to the primary opening area 28. For example, in one embodiment, auxiliary opening areas 32 are provided on both sides of a handle 34 of the present invention, as will be described in detail.
    Petition 870190035385, of 12/12/2019, p. 21/39
    16/27 [0043] In alternative modalities, a first opening area and a secondary opening area are opened or broken, using an additional or external tool, such as “Church Key” can openers. Thus, in various embodiments, permanent components, such as rivets and handles, need not be provided in central panels, in accordance with the present invention. Instead, areas of a central panel can be opened using additional tools.
    [0044] Referring now to figure 2, a top plan view of a metal end cap is provided, according to an embodiment of the present invention, where a handle has been rotated to a second position. As already discussed above, a pull handle 34 can be connected to a panel by means of a rivet 42, in a way that allows rotation of the pull handle. In one embodiment, a loop 34 of the present invention comprises an apparatus that limits the extent of rotation of the loop to a predetermined position. The rotation limiting means includes, but is not limited to, stationary projections and / or depressions arranged in a panel 14, adapted to contact additional parts of a central panel, such as a handle 34 or rivet island, as well as several other similar components , as should be perceived, by those skilled in the art. For example, in certain embodiments, a rotation guide 38 is provided to assist in guiding and / or limiting the trajectory and / or extension of loop rotation 34. In other embodiments, a loop position limiter 66 is provided in a central panel, to limit the extent of rotation of the loop 34. The loop position limiter 66 of the invention may comprise projections stamped into a central panel 14, to form a recess, or may comprise components, elements, or materials to be added to a central panel 14. In other modalities, the rotation can be defined and / or limited by added components or alloy
    Petition 870190035385, of 12/12/2019, p. 22/39
    17/27 to a panel 14, in addition to or in place of projections, indentations, or profiles formed from a panel 14.
    [0045] It is an aspect of the present invention to provide a rotational position limiter 66, which inhibits the rotation of a handle 34 in addition to a predetermined point, which corresponds to the preferred position of a handle 34 to open a secondary opening area 32. For example, in one embodiment, at least a peripheral wall portion of a rotation guide 38 touches the rotational position limiter, when the handle 34 is rotated to a position, where an additional elevation of the handle 34 opens an area of secondary opening 32, with a minimum amount of force and / or damage to the central panel 14.
    [0046] In another exemplary embodiment, a handle rotation guide 70 or recessed profile can be provided on a panel 14 to guide and / or limit the rotation of a handle 34, either in addition to or in place of a limiter arrangement. loop position 66 and rotation guide 38. For example, a recessed profile 70 can be provided to physically prevent loop rotation 34, in addition to a given point, by contacting a portion of the perimeter edge of the rotation guide 70 and / or provides visual information to the user with respect to the preferred maximum limit of the rotation of the loop 34.
    [0047] Referring now to figures 3A, 3B, 3C, 3D, top plan views representing an opening sequence of a modality of the present invention 10 are provided. Figure 3A is a top plan view of a metal end cap according to one embodiment, where a handle and a first opening portion are in a first closed position. A panel 14 is shown having a first opening area 28 with a passage 26 in a second closed position, a secondary opening area 32 with a secondary passage 27 in a first closed position, and a handle 34 affixed to a rivet 42 in
    Petition 870190035385, of 12/12/2019, p. 23/39
    18/27 a starting position.
    [0048] Figure 3B is a top plan view of a metal end cap, according to another embodiment of the present invention, in which a passage of the first opening portion has been opened. A central panel 14 is shown, where a handle 34 has been raised or rotated, so that a passage has been sheared from the portion of the panel 14 around primary marking line 30. Thus, a first opening area 28 has been opened to allow the contents of the container are poured or extracted. As shown in figure 3B, a secondary passage 27 and a secondary opening area 32 remain closed when the handle 34 is activated, in order to open a primary opening area 28 and a primary passage, due in part to the zone transition 54, primary marking termination component 50, and primary marking opening hinge 46. Therefore, a central panel of the present invention provides the user with the option of selectively opening only the first opening portion 28, where, for example , a ventilation component is not desired.
    [0049] Referring now to Figure 3C, a top plan view of a metal end cap is provided, according to an embodiment of the present invention, is provided, where a first opening portion has been opened, and a handle rotated to second position. A metal end cap is provided, where a first opening area 28 has been opened and the handle 34 is rotated to a second position to open a secondary passage 27 and secondary opening area 32. As discussed above, a handle 34 of the invention can be rotatingly affixed to the panel 14 via rivet 42. Thus, the handle 34 can be rotated to a position, in which a second lifting or rotating action applies a downward force on the secondary passage 27. As will be shown below in figure 3C, the limiting means
    Petition 870190035385, of 12/12/2019, p. 24/39
    19/27 rotation applies includes, but is not limited to, the recessed profile 70 adapted to bypass, outline, receive, etc. the geometry of one end of a loop 34 of the invention. The rotation limiting means may also include, for example, a position limiter 66, arranged on the panel 14, which extends a predetermined height of the panel 14, and being adapted to receive and / or limit the rotation of the handle 34, communicating with a rotational guide 38 in handle 34. In one embodiment, the rotation limiting means of the invention 10 visually identifies the preferred position, in which handle 34 must be rotated before turning or activating handle 34, and / or limiting rotation to one predetermined range desired to fracture a secondary marking line 62, and open the secondary opening area 32.
    [0050] Referring now to the 3D figure, a top plan view of a metal end cap according to an embodiment of the present invention is provided, in which a passage of the first opening portion has been opened, a handle 34 rotated to a second position, and a second opening portion is open. As shown, a rotatable handle 34 of the present invention was rotated to a second position, where handle 34 was raised or rotated by applying a downward force on a second pass, thus shearing the passage of the secondary marking line, and deflecting the passage around of the secondary marking opening hinge 74. Once the handle 34 is rotated to an appropriate extent and / or degree to open the optional ventilated area 32, the handle 34 can return to a position substantially parallel to the panel 14. The contents in the container10, then, it can be poured and / or consumed through the first opening portion 28, where the second opening area 32 facilitates the flow of content from the container 10, increasing the air flow to the container 10, and reducing the pressure of vacuum in the container, and facilitating the flow of liquid from container 10. Furthermore, as discussed
    Petition 870190035385, of 12/12/2019, p. 25/39
    20/27 seen above, and shown in figure 3B, it is not necessary for the user to open the secondary opening portion 32 of the present invention, when he wishes to provide a more conventional lid opening. Those skilled in the art should recognize that several ventilation openings 32 may be provided in the present invention. In one embodiment, the surface area of the optional vent opening 32 may comprise an area approximately between 2% and 40% of the original marking opening area.
    [0051] In an alternative embodiment, components of the present invention 10 can be incorporated into an end cap 14, which allows for the complete opening of a ventilation opening 32 with a single turning motion of the handle. Thus, in one embodiment, the present invention 10 does not comprise a transition zone 54, as shown and described therein. Instead, a secondary opening area 32 with a single marking opening joint 74 can be provided, where the fracture of a primary marking line 30 is not prevented from propagating to the second opening area 32 by the first movement and / or opening force.
    [0052] In one embodiment, a central panel is provided where at least one transition zone is provided between the first opening area and the second opening area, which does not require handle rotation to break the first marking line and the second line of dial. For example, a transition can be provided, which requires two distinct forces to break the first marking line and the second marking line, where the two distinct forces are not necessarily segregated or defined by the rotation of the handle.
    [0053] In one embodiment, a central panel is provided where the central panel has a primary marking opening area between 3.23 cm 2 and 4.84 cm 2 (0.50 in 2 and 0.75 in 2 ) . In another modality, the

    21/27 primary opening area has an area between 3.71 cm 2 and 4.03 cm 2 (0.575 inch 2 and 0.625 inch 2 ). In a more preferred embodiment, the primary opening area has an area of approximately 3.94 cm 2 (0.6111 in 2 ).
    [0054] In one embodiment, a secondary opening area is provided having an area between 0.13 cm 2 and 1.29 cm 2 (0.02 in 2 and 0.20 in 2 ). In another embodiment, the primary opening area has an area of 0.52 cm 2 and 0.65 cm 2 (0.08 inch 2 and 0.10 inch 2 ). In a more preferred embodiment, the secondary opening area has an area of approximately 0.59 cm 2 (0.0166 in. 2 ).
    [0055] In one embodiment, the total opening or openable area, ie the combined area of all opening areas provided in a central panel, is between 1.61 cm 2 and 9.68 cm 2 (0.25 in 2 and 1.5 in 2 ). In another modality, the total opening area of the central panel is between 3.87 cm 2 and 5.16 cm 2 (0.60 inches 2 and 0.80 inches 2 ). In a more preferred embodiment, the total opening area of an end cap is approximately 4.53 cm 2 (0.7027 in 2 ). Thus, in one embodiment, a secondary opening area comprises approximately 13.03% of the total opening area provided in a central panel. However, as those skilled in the art will appreciate, the primary or secondary opening areas can be of various sizes. Thus, in various modalities, a secondary opening area comprises between 5% to 25% of the total opening area.
    [0056] In various embodiments, the end caps provide a focal point for air to enter the container body, thus improving the condition of the liquid pouring from the container and the flow rate provided. In various embodiments, the secondary ventilation openings, as shown and described, increase the flow rate of the content from the container and provide an increase in flow of up to 30%, compared to conventional lids with a single area
    Petition 870190035385, of 12/12/2019, p. 27/39
    22/27 opening. In a particular embodiment, the time required to pour 340.19 grams (12 ounces) of fluid through an end cap of the present invention was about 4.25 seconds, compared to a time of approximately 5, 5 to 6, 0 seconds for a similar amount of fluid in conventional end caps.
    [0057] As should be recognized by those skilled in the art, the term "Area", as used in this, refers to a surface area of several opening portions, as defined by their respective marking lines, as shown and described in this one.
    [0058] Referring now to Figures 4A and 4B, top plan views of an embodiment of the present invention 10 are shown with a detailed view of a transition zone 54 provided. As shown in a detailed view, a primary marking line 30 comprises a primary marking termination component 50 at one end.

    [0059] Referring now to Figure 5, a top plan view of a metal end cap comprising an asymmetric handle 34 is shown. The handle 34 is provided having an asymmetric geometry adapted to open the primary marking component 30 and a secondary marking component 62 with a single opening operation (or double operation) (raising the handle 34). More specifically, the handle 34 includes an asymmetric projection, which extends over a secondary opening portion 32, adapted to contact a secondary passage 27 of the secondary opening area 32.
    [0060] In one embodiment, the central panel 10 comprises a secondary opening portion 32 with reinforcement engravings 78. Those skilled in the art should recognize that the reinforcement engraving 78 disposed in the secondary opening area 32 can take a number of forms ( square, round, oval, polygonal). Protruding or recessed engravings 78 can be arranged in the secondary passage 27 of the present invention to reinforce the central panel 27 and facilitate the rupture of the secondary marking line 58 during opening. Those skilled in the art should recognize that the design of the central panel requires careful balance of dimensions and parameters to ensure that the opening areas and other portions of a central panel are closed at the appropriate times (packaging and shipping) and are still able to open. through the application of reasonable force by the user. Therefore, the present invention contemplates that the secondary opening area 32 comprises one or more protruding and / or recessed engravings.

    [0062] Figure 6 is a top plan view of a metal end cap, according to one embodiment, in which two optional ventilation opening components 32, 33 are provided. As shown, the first opening area 28 it is arranged in a central panel with a secondary opening area 32 and a third adjacent opening area 33. In alternative embodiments, a third opening area 33 comprises the same components and function as the secondary opening area 32, as described. Thus, in certain embodiments, a first opening area 28 can be opened by applying a downward force through the nose portion 35 of the handle 34. The handle 34 can then be repositioned to allow rotation of the handle 34. The handle 34, then, can be rotated so that the nose portion of the handle 34 is arranged, at least partially, over a secondary opening area 32, and the handle 34 is
    Petition 870190035385, of 12/12/2019, p. 30/39
    25/27 rotated or raised to apply pressure to the secondary opening area 32 and separating a secondary passage 27. Subsequently, the handle 34 can be rotated back or restored to a position that allows the handle to rotate, and the handle 34 it is rotated so that it is partially arranged over the third opening area 33. The handle 34 can then be rotated or raised so that the nose portion of the handle 34 applies pressure to the third opening portion 33, and separate the third pass (or tertiary pass) from the panel. The handle 34 can then remain in the final position, or be repositioned, according to the user's preference, and the contents of the container can flow smoothly, facilitated by the plurality of optional ventilation openings.
    [0063] In certain embodiments, the secondary and tertiary passages can be opened without turning the handle 34. For example, in one embodiment, both the secondary 27 and tertiary passages 80 can be broken from the panel 14 along their respective lines. marking due to the application of a force, either by lifting or rotating the handle 34, but unlike the action of lifting and rotating the handle 34, used to open or break the first passage 26. Components of the present invention allow to lift the handle 34 with a distinct force, capable of breaking the primary passage 26. Following the application of the force, an additional distinct force can be applied in series to the secondary and tertiary passages.
    [0064] Referring now to Figures 7 and 8, top perspective views of a metal end cap 10 according to an embodiment are provided. As shown, a rotation limiting means can be provided to prevent loop rotation 34 beyond a predetermined position. The rotation limiting means of the present invention includes, but is not limited to, panel projections and indentations 34, which are capable of communicating with loop portions 34.
    Petition 870190035385, of 12/12/2019, p. 31/39
    26/27
    For example, as shown in figure 7, a projection can act as a speed limiting guide 82, adapted to interact or communicate with a portion of the rivet island 84. In certain embodiments, a peripheral portion of a segment of the rivet island 84 contacts a peripheral portion of the rotation guide 82 in a first position. The contact between the guide 82 and the rivet island portion 84 in a first position corresponding to the handle is arranged in a position adapted to open the primary opening area 28. The contact between the rotation guide 82 and the rivet island 84 prevents rotation beyond a point, without, however, restricting or limiting the turning condition of the handle 34, to apply a force on one or more opening areas.
    [0065] As shown in figure 8, a handle 34 was rotated to the maximum permissible extent, defined by a second point of contact between a rivet island portion 84 and the rotational guide 82. As those skilled in the art should recognize the maximum extent of rotation allowed by the rivet island portion 84 and rotational guide 82 corresponds to the rotational position of the handle 34, which is adapted to easily open one or more ventilation openings, as described herein.
