[0001] [001] This disclosure relates to, incorporates by reference, and claims priority for the US patent application entitled "Easy-Pull Bottle Cap", filed on October 6, 2011 and assigned US 13 / 267,264, and patent application US entitled "Bottle Crown", 12 / 903,533, filed on October 13, 2010, which in turn claims priority of US patent application 11 / 698,247, filed on January 24, 2007 (issued as US patent 8,061,544 ), which is partly a continuation of the copending PCT patent application of the same title serial number PCT / US2006 / 002421 by the same inventor, filed on January 24, 2006 and entitled EASY-PULL BOTTLE CAP. FIELD OF DISSEMINATION
[0002] [002] The present disclosure relates to caps and crowns for beverage bottles and other containers and, in particular, to a reduced-gauge corrugated bottle cap. FUNDAMENTALS
[0003] [003] US patent application published 12 / 597,385 to Merino Caballero ("Caballero") discloses a low gauge crown cap in which the top panel displays grooves in various formats, depending on the modality, to achieve corrugation and obtain a crown which has a low gauge of crown material, such as steel. Although it is not state of the art due to a priority date subsequent to the priority date of the present disclosure, the present inventor recognizes that the application for Caballero because it was published before the filing date of this disclosure.
[0004] [004] The related application serial number 12 / 903,533, and its parent 11 / 698,247 (issued as US patent 8,061,544), referenced above, disclose a bottle crown that has a seat on which rests a pull tab assembly , so that the pull tab assembly is flush with the top of the crown. The seat is formed through a depression or recess in the upper part of the crown. A benefit of the recessed upper part is that the recess functionality acts to corrugate the upper part of the crown. As is well understood, the corrugation has the advantage of stiffening a sheet of material against forces that are perpendicular to the corrugation direction. That is, a corrugated sheet is harder to fold than an uncorrugated sheet, at least in certain directions. A bottle crown that has corrugation through its upper part will be more rigid than an uncorrugated crown. Therefore, to achieve the same degree of stiffness as an uncorrugated crown, a corrugated crown may be thinner or have a lower gauge of crown material, such as steel or tinplate. The advantages of corrugation that are implicitly inherent in the crown of the '533 application are made explicit in the present disclosure. The present disclosure, therefore, describes a corrugated crown and its advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] [0013] Figure 1 is an isometric side view illustration of a reduced gauge crown of the present invention. Crown 100 includes top portion 110 contiguous with recess 120 which ends at panel 130. Skirt 140 extends downwardly from top 110. In some specific embodiments a flange extends obliquely from skirt 140. Grooves 150 and loins 152 alternate they are formed in a circumferential portion of the skirt 140. The crown 100, and other crowns shown in the figures, are shown as a type of recess that is opened with a lever. The present invention also encompasses a type of twisting (not shown in the figures) that is opened by twisting, as will be understood by those familiar with crown cap technology. Finally, crown 100 is suitable for use with pull tab type assemblies mounted on panel 130 with effective groove lines engraved on crown 100.
[0014] [0014] Panel 130 is recessed, that is, it is lower than the upper part 110, but is contiguous with the upper part 110 due to the transition surface 120, which will be referred to in this document for convenience as recess 120 The recess 120 can be formed in the crown 100 in a variety of ways suitable to provide advantageous shapes. For example, in specific exemplary modes, rows, grooves or steps are integrally formed in the material of the crown 100 until the desired depth of panel 130 is obtained, as shown in Fig. 1. In an alternative embodiment, the recess 120 is formed with a surface gently curved from the top 110 to the panel 130. The shape of the recess 120 functions as ribs or structural reinforcements that are supposed to help to tighten the panel 130 against deflection or deformation.
[0015] [0015] The skirt 140 descends from the upper part 110 along the outer perimeter of the crown 100 and in specific exemplary forms it smoothly merges into a flange extending downwardly and radially externally. The skirt 140 is preferably adapted to be embedded in the neck of a bottle for sealing. Exemplary specific modalities of skirt 140 are divided into wavy, repeated portions that define grooves 150 and loins 152. Preferably, the repeated portions are circumferentially uniformly spaced apart, so that each groove 150 is identical to all other grooves 150 in around the circumference of the crown cap 100, and each loin 152 is identical to all other loins 152 around the circumference of the crown cap 100. It should be understood that the crown cap 100 can include any number of grooves 150 and loins 152 .
[0016] [0016] With reference now to Figs 2A and 2B, 3A and 3B and 4A and 4B, the reference "B" of each represented modality is the horizontal cross section of its counterpart "A" through line B-B. Each modality, designated 2A / B, 3A / B and 4A / B, is characterized by a particular diameter of its panel 130, as represented by the width B 210, 310 and 410 of each modality, respectively, and by the depth A of the recess 120 represented by depths 220, 320 and 420, respectively.
[0017] [0017] A specific amount of resistance of corrugation material is achieved by selecting a modality with a particular combination of panel diameter 210, 310 or 410, for example, and recess depth 220, 320 or 420, for example. Exemplary modality 2A / B, for example, has panel diameter 210 which is relatively wide and recess depth 220 which is intermediate deep. The exemplary modality 3A / B has panel width 310 which is of intermediate width and recess depth 320 which is the deepest of the three exemplary modalities. The exemplary modality 4A / B has panel diameter 410 which is the narrowest of the modalities and recess depth 420 which is the shallower depth of the three modalities. To obtain a desired amount of corrugation material strength, a combination of panel width 210, 310, or 410, for example, and recess depth 220, 320 or 420, for example, is selected to achieve a specific modality.
[0018] [0018] Corrugation stiffens materials. This is particularly true for laminar materials formed on a sheet or plane. A laminar product can use less than one material if the material is corrugated to provide lateral strength. A bottle cap is a laminar product in which the sheet material, often steel or tinplate, is shaped to be attached to the top of a bottle or other container. A standard peel or untwist lid has a material thickness that is predominantly determined by considerations of leak prevention and the safety of fixing the lid to the container.
[0019] [0019] Billions of bottle caps are used worldwide and the cost of the caps is largely determined by the amount of material required for the caps. Corrugation allows lids that use less material to have the equivalent strength of a standard thickness crown. A corrugated crown is thinner, that is, it has a reduced gauge compared to a standard bottle cap. An advantage of a reduced gauge cap is the money savings achieved by using less material.
[0020] [0020] Another advantage of a reduced-gauge corrugated cover comes on the scene with innovative "pull" covers which have a pull-tab assembly attached to the crown as described in the relative patent applications. The pull tab breaks the cap material and the crown is torn from the bottle using the pull tab. A reduced gauge lid facilitates tearing because the lid material is thin and the tearing action is parallel to the direction of resistance of the material provided by the corrugation and therefore the tearing force does not have to overcome the resistance of the corrugation material. Corrugation gives material strength perpendicular to the corrugation direction.
[0021] [0021] In addition to the structures illustrated in the figures in this document, it is understood that other structures will imbue a lid of the present disclosure with the advantages of corrugation and will provide a reduced gauge crown for a bottle. For example, concentric rings which progress from the top of the skirt towards the center of the panel and decorative shapes, such as stars, brand logos, sports team logos, religious insignia, and the like, formed in the plane of the cover are included in the cover. present disclosure.
[0022] [0022] Corrugation forms can be supplied to a bottle cap by a variety of means, including without limitation, metal stamping, pressing, engraving and so on. Non-metallic crowns of the present disclosure can be formed by injection molding for plastic crowns, or by other suitable means of production.
[0023] [0023] Crown caps 100 are preferably formed from high hardness steel as compared to conventional crown caps presently in commercial production. For example, conventional crown lids are often formed from simple reduced T4 tinplate having a thickness of 0.21 mm to 0.23 mm. This tinplate has an average hardness (that is, the hardness value reported independently of variations +/-) of approximately 61 on a 30T hardness scale, according to ASTM 623. Crown caps 100 described in this document can thinner and lighter in weight compared to the state of the art, for example, crown caps 100 can be formed of a material having a thickness of about 0.16 mm to 0.18 mm that has the same performance or roughly equal to conventional thicker caps. These decreases in metal use are most easily achieved when the structure of the crown caps 10 is made of steel having high hardness. For example, the inventor demonstrated the effectiveness of low-gauge crowns having grooves using DR8 (according to ASTM 623) or DR550 (according to EN 10203). Optionally, the inventor assumes that other materials can be used, such as simple reduced tinplate or similar material having an intensifying quench, tin-free steel having properties similar to those described in this document and the like.
[0024] [0024] Crown caps 100 preferably have an average hardness greater than 62 on the 30T scale (according to ASTM 623), more preferably greater than about 65, more preferably greater than about 68, more preferably greater than about 71. The embodiments shown in FIG. 1 and FIG. 3A have been shown to be effective using steel having a hardness of 73. The upper hardness limit is adjusted by the maximum acceptable tension for the glass bottle during the crimping process or the return of the girl (which may tend to propel the flanges crimped in towards a non-driven state) associated with the hardest plate.
[0025] [0025] Crown caps 100 can be formed with conventional press equipment, with only minimal changes in parts of the tooling to form the structure (such as grooves, crosspieces, stars and jerks). And crown caps 100 can be driven with conventional equipment, only modified to have a smaller throat compared to existing conventional drive drivers.
[0026] [0026] As the hardness has a relation with strength as reflected in the flow point, the aspect of the crown hardness can be expressed in the flow point in a corresponding scale. For example, tinplate DR8 or DR550 can have a yield point (in a tensile test) of 550 MPA. The inventor believes that the most advantageous crown cap has a combination of one or more of the structures described in this document and the harder plate as described in this document. A crown in the present disclosure, however, encompasses crown covers that do not have all the structure, materials and / or advantages in this specification.
[0027] [0027] According to this description, commercially acceptable crown caps formed in accordance with the present disclosure can be made commercially with up to 25 percent less steel compared to many conventional crown caps, which has corresponding advantages in carbon emissions. The steel weight savings are approximately proportional to the reduction in metal thickness. In addition, while the energy required to cool an individual crown is minimal, the energy required to cool the total number of crowns produced each year (approximately 45 billion in North America and approximately 300 billion worldwide) and the reduction corresponding to that energy are significant.
[0028] [0028] In addition to the various structures described in this document, certain advantages over the state of the art are given in the present crown by the recommended specifications shown in Table 1.
[0029] [0029] In particular, a tinplate material which demonstrates an approximate T-4 hardness on the Rockwell Dueza 30T Scale is preferred for the present cover (see item 3 in table 1). This can be contrasted against the state of the art which typically uses tinplate having a K-3 hardness on the Rockwell scale. The preferred softer tinplate material requires less force to open and tear with the present crown opener assembly, while still providing sufficient sealing of the container contents. For the purposes of this disclosure, tinplate refers to any material, including tin or tin alloys, from which a crown can be manufactured and does not necessarily mean that the crown is made of tin or a tin alloy.
[0030] [0030] The foregoing description is provided for the purpose of explanation and should not be construed as limiting the invention. Although the invention has been described with reference to preferred embodiments or preferred methods, it is understood that the words which have been used in this document are words of description and illustration, rather than words of limitation. In addition, although the invention has been described in this document with reference to the particular structure, methods and modalities, the invention is not intended to be limited to the particularities disclosed in this document, as the invention extends to all structures, methods and uses that are within the scope of the appended claims. Those skilled in the relevant technique, having the benefit of the teachings of this specification, can make numerous modifications to the invention as described in this document and changes can be made without departing from the scope and spirit of the invention as defined by the appended claims. In addition, any aspects of a described modality may apply to other modalities described in this document.
[0031] [0031] These modalities of the inventive object may be referred to in this document, individually and / or collectively, by the term "invention" merely for convenience and without intending voluntarily to limit the scope of this request to any single invention or inventive concept if more than one is in fact disclosed. Thus, while specific modalities have been illustrated and described in this document, it should be appreciated that any provision calculated to achieve the same purpose can be used in place of the specific modalities shown. This disclosure is intended to cover any and all adaptations or variations of various modalities. Combinations of the above modalities and other modalities not specifically described in this document will be apparent to those skilled in the art upon review of the above description.
[0032] [0032] In short, the present disclosure describes a crown for a container opening. The crown has an upper portion and an inner portion contiguous with the upper portion. The inner portion is formed in a panel. An outer portion contiguous with the upper portion is formed into a skirt that descends from the upper portion. The crown has corrugation formed on the panel.
[0033] [0033] The present disclosure also contemplates methods for making the crown described above. Methods include the steps of molding a sheet of crown material to provide an upper portion and an inner portion contiguous with the upper portion and formed in a panel. An outer portion contiguous with the upper portion is formed into a skirt that descends from the upper portion. The methods also include forming corrugation on the panel.
[0034] [0034] In specific modalities, the step of forming corrugation in the panel consists of forming a recess that descends from the upper portion to the panel in the internal portion.
[0035] [0035] The Disclosure Summary is provided to meet 37 C.F.R. §1.72 (b), requiring a summary that will allow the reader to quickly confirm the nature of the technical disclosure. It is presented with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the preceding Detailed Description, it can be seen that several aspects are grouped together in a single modality for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed modalities require more aspects than expressly recited in each claim. Instead, as the claims reflect, the inventive subject matter is located in less than all aspects of a single disclosed modality. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim supported on its own as a separate modality.
[0036] [0036] The description made reference to several exemplary modalities. However, it is to be understood that the words that were used are words of description and illustration, rather than words of limitation. Changes may be made within the scope of the appended claims, as currently stated and as amended, without departing from the scope and spirit of the disclosure in all its aspects. Although the description makes reference to particular means, materials and modalities, the disclosure is not intended to be limited to the particularities disclosed; instead, the disclosure extends to all functionally equivalent technologies, structures, methods and uses, as they fall within the scope of the appended claims.
