Description

BACKGROUND

Commercial beverage containers are provided with “pilfer proof” or “tamper-evident” features to ensure consumer safety. Such features are generally externally visible indicia of whether a container has been opened. Common stay-tab cans, for example, enable a user to know whether the can has been opened by observing whether the scored metal around the tab has been broken apart.
As beverage containers, cans are associated with a number of environmental advantages, such as recyclability and reusability. However, some varieties of beverage cans, including stay-tab cans, are generally not resealable. Consumers who wish to reseal beverage containers may therefore be discouraged from purchasing beverages packaged in cans.

BRIEF SUMMARY

A need exists for a can design that is both resealable and pilfer-proof or tamper-evident. Accordingly, aspects of the present disclosure are directed to a can including a lid that in turn includes a cap and a tamper-evident band. The band can be configured to readily indicate whether the cap has been removed from the can after the initial fill and assembly of the can. The band can initially be integrally formed with the cap and connected to the cap by a frangible connection. The frangible connection can be configured to irreversibly break when the cap is removed from the can. The collar can include a neck ending at an outlet covered by the cap, and the band can have an internal diameter less than an external diameter of a shoulder formed in the neck between the band and the outlet. The shoulder can therefore prevent the band from travelling off the neck when the cap is removed from the collar. The collar can define a trough located within a body of the can. The collar can further include a cuff extending from the trough, beyond the band, to a lip where the cuff is secured to a rim of an opening of the body of the can.
According to an aspect of the present disclosure, a beverage can may comprise a can body and a lid. The can body may comprise an opening. The lid may be joined to the can body and cover the opening. The lid may comprise a collar, a cap, and a band. The collar may be separately formed from the can body. The collar may comprise a neck that comprises a threaded portion. The cap may be threadedly engaged with the threaded portion of the neck. The band may be frangibly connected to the cap. The band may encircle the neck. The band may be integrally formed with the cap and separately formed from the collar. The cap, band, and neck may be respectively configured to cause the band to break away from the cap when the cap is threadedly disengaged from the neck.
In some embodiments according to any of the foregoing, the neck may comprise an outlet and a shoulder. Part of the threaded portion may be located between the shoulder and the outlet. The shoulder may have an external diameter. The cap may have an internal diameter. The internal diameter may be less than the external diameter.
In some embodiments according to any of the foregoing, the opening may be defined at an upper end of the can body. The neck may extend below the upper end of the can body.
In some embodiments according to any of the foregoing, the band may be positioned below the upper end of the can body in a circumferential recess defined between the neck and the can body.
In some embodiments according to any of the foregoing, the threaded portion of the neck may extend below the upper end of the can body.
In some embodiments according to any of the foregoing, the cap may have a diameter at least two thirds as great as a diameter of the can body.
According to another aspect of the present disclosure, a beverage can may comprise a can body and a lid. The can body may define an interior. The lid may be joined to the can body. The lid may comprise a collar, a cap, and a band. The collar may comprise a neck and an outlet. The outlet may be in fluid communication with the interior of can body. The neck may extend from the outlet into the can body. The neck may comprise a threaded portion. The cap may be threadedly engaged with the threaded portion of the neck. The band may be frangibly connected to the cap and encircles the neck. The band may be integrally formed with the cap. The band may be separately formed from the collar. The band may be positioned within the can body. The cap, band, and neck may be respectively configured to cause the band to break away from the cap when the cap is threadedly disengaged from the neck.
In some embodiments according to any of the foregoing, the collar may comprise a cuff surrounding a portion of the neck.
In some embodiments according to any of the foregoing, the can body may comprise a rim and the collar comprises a trough. The neck may be connected to the cuff at the trough. The cuff may extend upward from the trough to the rim.
In some embodiments according to any of the foregoing, the rim defines an upper end of the can body.
In some embodiments according to any of the foregoing, the cuff may comprise a lip folded over the rim.
In some embodiments according to any of the foregoing, the neck may comprise a shoulder. A part of the band located on an opposite side of the shoulder from the outlet may have an internal diameter that is less than an external diameter of the shoulder.
According to another aspect of the present disclosure, a method of forming a beverage container may comprise assembling a cap precursor together with a cylinder. The method may also comprise converting the cap precursor and cylinder to a lid. Converting the cap precursor and cylinder to a lid may comprise securing the cap precursor to the cylinder by forming a threaded portion and a band in the cap precursor, wherein the threaded portion and the band are integrally formed and the band is configured to separate from the threaded portion when the threaded portion is threadedly disengaged from the cylinder. Converting the cap precursor and cylinder to a lid may also comprise folding part of the cylinder over the band to define a cuff surrounding the band. The method may also comprise securing the lid to a body that defines an interior and an opening so that the lid covers the opening.
In some embodiments according to any of the foregoing, the method may comprise forming a lip at an upper end of the cuff for joining the lid to the body.
In some embodiments according to any of the foregoing, the method may comprise folding the part of the cylinder beyond the band so that the cuff surrounds the part of the threaded portion.

When a particular feature, structure, or characteristic is described in connection with the embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.
The terms “invention,” “present invention,” “disclosure,” or “present disclosure” as used herein are non-limiting terms and are not intended to refer to any single embodiment of the particular invention but encompasses all possible embodiments as described in the application.
FIGS. 1A and 1B show a can 100 including a body 110 and a lid 140. Can 100 can be constructed using a body 110 alike to a conventional can body alike to those already known for use in beverage packaging. Thus, body 110 includes an interior wherein product, such as a beverage or other liquids, can be contained. Body 110 also includes a closed base 112. Base 112 of the illustrated example is located at an end opposite from lid 140, but can be positioned otherwise relative to lid in other examples.
Because lid 140 is compatible with conventional can bodies, lid 140 may be incorporated into existing manufacturing and filling facilities and processes for cans with relatively little modification to those facilities and processes. Thus, the benefits of lid 140 may be available in return for relatively small investments. Existing supply chains for conventional can bodies and markets for canned goods can also be maintained.
As shown in FIG. 1B, body 110 also includes an opening 116 at an end opposite from base 112. Opening 116 is in fluid communication with the interior of body 110, meaning liquid or other stored product can exit body 110 through opening 116. Lid 140 covers opening 116 when can 100 is assembled as shown in FIG. 1A. Body 110 further includes a rim 114 surrounding opening 116. When can 100 is assembled as shown in FIG. 1A, lid 140 is coupled to rim 114 to seal opening 116.
Lid 140 includes a collar 142 and a cap 144. When can 100 is assembled as shown in FIG. 1A, collar 142 is coupled to body 110 about opening 116 and cap 144 is coupled to collar 142. Body 110 of the illustrated example includes a rim 114 surrounding opening 116 to facilitate coupling collar 142 to body 110 as will be detailed below.
Collar 142 of the illustrated example further includes a lip 146 for coupling to rim 114. Lid 140 is configured to prevent passage of liquid between body 110 and collar 142 when can 100 is fully assembled as shown in FIG. 1A. Collar 142 includes an outlet 154 that is in fluid communication with opening 116. Outlet 154 is therefore also in fluid communication with the interior of body 110. Liquid can therefore leave body 110 through opening 116 then pass through outlet 154 to exit can 100 when collar 142 is coupled to body 110.
Cap 144 is configured to cover outlet 154 and lid 140 is further configured to prevent passage of liquid between collar 142 and cap 144 when can 100 is fully assembled as shown in FIG. 1A. In particular, cap 144 can be threadedly engaged with can seal outlet 154 when cap 144 is threadedly engaged with a neck threaded portion 152 formed in collar 142. Cap 144 can seal outlet 154 when cap 144 is threadedly engaged with neck threaded portion 152. Lid 140 thereby seals opening 116 when can 100 is fully assembled as shown in FIG. 1A. Accordingly, when collar 142 is coupled to body 110, opening 116 can be sealed by using cap 144 to cover outlet 154 and opening 116 can be unsealed by removing cap 144 from collar 142.
In some examples, collar 142 can be permanently coupled to body 110 and cap 144 can be reversibly coupled to collar 142. Thus, in such examples, collar 142 can remain fixed to body 110 while cap 144 is repeatedly coupled to and uncoupled from collar 142 to selectively seal or unseal opening 116.
Cap 144 of the illustrated example is relatively wide in proportion to body 110. In the illustrated example, a cap diameter 145 is more than two thirds as great as a body diameter 111. Cap diameter 145 is measured across a widest portion of cap 144. In various further examples, cap diameter 145 can be at least one quarter as great as body diameter 111, at least one third as great as body diameter 111, at least half as great as body diameter 111, or at least two thirds as great as body diameter 111. The relatively large cap diameter 145 of the illustrated example enables outlet 154 to also have a relatively large diameter. In some examples, a diameter of outlet 154 can be at least 60%, at least 70%, at least 80%, or at least 90% as great as cap diameter 145. A large diameter of outlet 154 facilitates certain actions that can be difficult with some known beverage cans such as refilling can 100 and adding ice cubes or other solids to can 100, which may make can 100 appealing as a reusable container. A large diameter of outlet 154 may also be more natural to drink from than openings formed in stay tab can tops, leading to a better user experience. The opening provided by a large outlet 154 may be relatively similar in usage to cups, tumblers, or mugs, which many users prefer to the small opening provided in stay tab can tops. Additionally, a large outlet reduces the likelihood that a user will experience “glugging,” where the flow rate out of the can varies as the fluid periodically occludes the outlet, which occurs frequently in stay tab can tops.
Cap 144 of the illustrated example also has a flat top. The flat top can extend across a majority of the can diameter, as shown in the illustrated example. In some examples, the flat top can span at least 80%, at least 90%, at least 95%, or 100% of cap diameter 145. The flat top of cap 144 combined with the relatively large cap diameter 145 of the illustrated example makes can 100 easy to stack with other alike cans 100. This ease of stacking may make can 100 relatively efficient to handle, which may reduce distribution costs. In further examples, cap 144 may have a top with a shape that is not flat. Some cans 100 according to such further examples have bases 112 shaped complementarily to the tops of caps 144 and are therefore also stackable.
Collar 142 includes a neck 153. Neck 153 includes a neck threaded portion 152 for engaging corresponding cap threading 167 formed in cap 144. Collar 142 further includes a cuff 148 extending between lip 146 and neck 153. In the illustrated example, cuff 148 extends upward from a lower end of neck 153 to an upper end of lip 146. Cuff 148 thus doubles back over neck 153 so that a gap 150 defined between neck 153 and cuff 148 surrounds neck 153. Gap 150 extends down to a trough 149 formed where neck 153 transitions to cuff 148. Because cuff 148 extends downward from lip 146, and collar 142 is joined to rim 114 at lip 146, cuff 148 extends downward into an interior space of body 110. Neck 153 therefore also extends below an upper end of body 110. Rim 114 defines an upper end of body 110 in the illustrated example, though body 110 may include additional features extending higher than rim 114 in other examples.
Lid 140 further includes a band 156 that encircles neck 153. Band 156 is frangibly connected to cap 144. Band 156 can be configured such that when can 100 is in the fully assembled state shown in FIG. 1A, band 156 is positioned within a lower portion of gap 150, near trough 149 and below some or all of neck threaded portion 152. In the illustrated example, trough 149 is below an upper end of body 110 such that a portion of gap 150 adjoining trough 149 is a circumferential recess defined between body 110 and neck 153.
Band 156 can further be configured to be incapable of passing upward beyond neck threaded portion 152, meaning band 156 can provide resistance to unthreading cap 144 from neck 153. When enough unthreading force is applied to cap 144, the frangible connection between cap 144 and band 156 may break, causing band 156 to separate from cap 144. Cap 144, band 156, and neck 153 are therefore collectively configured to cause band 156 to break away from cap 144 while cap 144 is being threadedly disengaged from neck 153. After cap 144 breaks from band 156, cap 144 can be freely unthreaded from neck 153.
However, cap 144 may be impossible to unthread from neck 153 before cap 144 breaks from band 156. Outlet 154 and opening 116 may therefore be impossible to unseal without breaking cap 144 from band 156. Band 156 can therefore serve as an irreversible tamper indicator for can 100. Thus, a user can reliably determine whether outlet 154 and opening 116 have ever been unsealed after the original fill and construction of can 100 by observing the presence or absence of the frangible connection between band 156 and cap 144. Band 156 is therefore tamper evident.
Band 156 can be frangibly connected to lid 140 by a frangible link 174, as shown in more detail in FIGS. 1C and 1D. Link 174 can be any feature configured to irreversibly break when cap 144 is removed from neck 153 so that band 156 will not travel past a certain point of neck 153. Link 174 has a lower effective tensile yield strength than cap 144 and band 156 in the direction that cap 144 travels when being removed from neck 153, meaning link 174 will break while cap 144 and band 156 remain individually intact when enough removal force is applied to cap 144.
Link 174 of the illustrated example is a portion of material that is integrally formed with cap 144 and band 156, but having lower effective tensile yield strength than cap 144 and band 156. In particular, link 174 of the illustrated example is a perforated ring located between band 156 and cap 144. The perforated ring includes a plurality of gaps 173 and a plurality of tabs 175.
Tabs 175 connect band 156 to cap 144. Tabs 175 are separated circumferentially from one another by gaps 173. Gaps 173 are each positioned between band 156 and cap 144, link 174 as a whole includes less solid material and more features conducive to stress concentrations per unit volume than band 156 or cap 144, causing link 174 to have the lower effective tensile yield strength than cap 144 and band 156. In other examples, link 174 can include structures other than that of the illustrated example, such as a ring of material that is weaker than the materials of band 156 and cap 144, or a porous portion of material integrally formed with both band 156 and cap 144.
In the illustrated example, cuff 148 extends far enough from trough 149 that cuff 148 and gap 150 surround band 156. Cuff 148 extending to or beyond the height of band 156 can inhibit tampering or incidental damage to band 156, and may therefore contribute to band's 156 reliability as an indicator of whether cap 144 has been removed from can 100. Further according to the illustrated example, cuff 148 extends beyond band 156 such that cuff 148 and gap 150 surround a part of neck threaded portion 152. However, in other examples, cuff 148 may not extend to neck threaded portion 152. In further examples, cuff 148 may not extend to band 156, meaning band 156 may be further from trough 149 than lip 146.
FIG. 1D schematically represents a portion of lid 140 where band 156 abuts a portion of neck 153 in cross-section. Turning to FIG. 1D, neck 153 includes a shoulder 176. Shoulder 176 is a tamper evident formation that cooperates with band 156 to provide evidence of whether cap 144 has been removed from outlet 154 after the initial manufacture and fill of can 100. Shoulder 176 of the illustrated example is a portion of neck 153 immediately below which an external diameter of neck 153 decreases. Accordingly, shoulder 176 has a shoulder external diameter 177 greater than a local external diameter 179 of neck 153 at a point between shoulder 176 and trough 149. Band 156 has an internal diameter 157 at a point located on an opposite side of shoulder 176 from outlet 154 that is less than the shoulder external diameter 177. Thus, band 156 cannot travel upward along neck 153 to a position entirely above shoulder 176 unless either or both of band 156 and shoulder 176 deform. Shoulder 176 is defined below the upper end of neck threaded portion 152. Thus, at least part of neck threaded portion 152 is located between shoulder 176 and outlet 154. Shoulder 176 therefore also prevents band 156 from traveling beyond neck threaded portion 152.
Shoulder 176 of the illustrated example is a circular protrusion defined entirely below neck threaded portion 152, though in other examples shoulder 176 can have a non-circular shape. In some further examples, shoulder 176 can be shaped as an interrupted circle, including multiple spaced apart radial protrusions from neck 153.
Link 174 is configured to break when removing force on cap 144 presses band 156 against shoulder 176 with at least a breaking force. The breaking force is lower in magnitude than force in the same location and direction that would cause band 156 or shoulder 176 to deform enough to allow band 156 to pass entirely above shoulder 176. Thus, removing cap 144 from neck 153 will cause link 174 to break, thereby separating band 156 from cap 144.
Can 100 can be constructed entirely of metal. Can 100 may therefore be completely recyclable. Can 100 may also be easily reusable and compatible with a wide variety of beverages. Suitable materials for constructing can 100 include any metals and alloys known for construction of beverage cans, including, for example, aluminum and stainless steel.
Lid 140 can be constructed by a roll-on process wherein the threads in cap 144 are formed in the same step that joins cap 144 to collar 142. Lid 140 can be constructed according to a process for converting a collar precursor 241 and cap precursor 243 to a lid 240 for a can 200 depicted in FIGS. 2A-2E and described below. Elements of can 200 are numbered alike to like features of can 100, such as collars 142, 242 and caps 144, 244. Thus, any qualities or possibilities described with regard to the elements shown in FIGS. 1A-1D may be equally true for the elements shown in FIGS. 2A-2E, and any qualities or possibilities described with regard to the elements shown in FIGS. 2A-2E may be equally true for the elements shown in FIGS. 1A-1D.
As shown in FIG. 2A, a collar precursor 241 can include a cylinder 260 that defines an outlet 254 at first open end and an inlet 264 at a second open end opposite the first open end. Turning to FIG. 2B, a cap precursor 243 can be placed on collar precursor 241 to cover outlet 254. Cap precursor 243 includes an end wall 266 configured to cover outlet 254 and a side wall 268 that extends from end wall 266. In the stage illustrated in FIG. 2B, cap precursor 243 is placed so that end wall 266 covers outlet 254 and side wall 268 covers part of an exterior of cylinder 260. Side wall 268 can be, for example, cylindrical in shape, though non-cylindrical side walls 268 are possible in other examples.
Cap threaded portion 267 and band 256 can be formed to bring the assembly shown in FIGS. 2A and 2B to the stage shown in FIG. 2C. At the stage shown in FIG. 2C, cap precursor 243 has become cap 244, band 256, and link 274. Cap 244 includes the top wall 266 and side wall 268 originally included by cap precursor 243, excluding any portion of side wall 268 that became band 256 and link 274.
Forming cap threaded portion 267 can include applying lateral, meaning horizontal with respect to the perspective of FIGS. 2A-2C, force to side wall 268 to deform side wall 268 to have helical threading. Such lateral force can be applied, for example, by applying a thread forming tool 271 to the exterior of side wall 268. The same or another tool can be used to bend a portion of side wall 268 to form band 256. A perforating tool 283 can be applied to side wall 268 in a circular path to form link 274. In various examples, perforating tool 283 can be applied to form link 274 while cap precursor 243 is assembled with collar precursor 241 and before, during, or after application of thread forming tool 271. In further examples, link 274 can be formed in cap precursor 243 before cap precursor 243 is assembled with collar precursor 241.
Neck threaded portion 252 and shoulder 276 can be formed in cylinder 260 simultaneously with the formation of cap threaded portion 267 and band 256, respectively. For example, thread forming tool 271 used to form cap threaded portion 267 can be applied with enough force to also create neck threaded portion 252 in the course of forming cap threaded portion 267.
Similarly, the tool used to form band 256 can be applied with enough force to also create shoulder 276 in the course of forming band 256. In such examples, a shaping tool 281 having the shape of threaded portions 252, 267 can be placed inside of cylinder 260 and side wall 268 while threaded portions 252, 267 are formed by pressing cylinder 260 and side wall 268 onto shaping tool 281. In further such examples, a shaping tool having the shape of band 256 and shoulder 276 can be placed in side of cylinder 260 and side wall 268 while band 256 and shoulder 276 are formed by pressing side wall 268 and cylinder 260 onto the shaping tool. The shaping tool 281 used to form the threaded portions 252, 267 can be the same shaping tool as or a different shaping tool from the shaping tool used to form the band 256 and shoulder 276.
In other examples, neck threaded portion 252 and shoulder 276 can be formed in cylinder 260 before cap threaded portion 267 and band 256 are formed. In such latter examples, cap threaded portion 267 and band 256 can be formed by deforming side wall 268 to conform more closely to the preexisting shape of neck threaded portion 252 and shoulder 276 of cylinder 260. In the examples wherein neck threaded portion 252 and shoulder 276 are formed in cylinder 260 before cap threaded portion 267 and band 256 are formed, neck threaded portion 252 and shoulder 276 can optionally be formed in cylinder 260 at the stage depicted FIG. 2A, when cap precursor 243 is not yet assembled with collar precursor 241 to form the assembly shown in FIG. 2B.
A portion of cylinder 260 that is located between neck threaded portion 252 and inlet 264 in the stage illustrated in FIG. 2C can be folded outward and upward to convert collar precursor 241 to collar 242 as shown in FIG. 2D. Collar 242 includes a cuff 248 and neck 253, wherein neck 253 includes neck threaded portion 252. With cap 244 already assembled to collar precursor 241, the conversion of collar precursor 241 to collar 242 creates lid 240. Lid 240 can be assembled to a body 210 to form a can 200.
At least part of the folded portion of cylinder 260 becomes cuff 248 and trough 249. In the illustrated example, a further part of the folded portion of cylinder 260 further becomes lip 246. Further according to the illustrated example, the folded portion of cylinder 260 is folded to a height above a lower end of neck threaded portion 252 so that cuff 248 and gap 250 surround part of neck threaded portion 252. Still further according to the illustrated example, the folded portion of cylinder 260 is folded to a height above a lower end of cap 244 so that cuff 248 and gap 250 surround part of cap 244.
