Abstract
A beverage container is disclosed including a cylindrical body defining a volume configured to hold a liquid beverage and a neck having at least one slanted sidewall extending inwardly from and about a circumference of a first end of the cylindrical body. The beverage container also includes a lid sealed with one end of the neck. The lid has a top planar portion with one or more score lines that define a primary opening when ruptured to provide a flow of the liquid beverage to a consumer when the beverage container is tilted from vertical. The beverage container also includes a lip relief extending inward and only partially circumventing an area of the neck. The lip relief is aligned with the primary opening and is dimensioned to accept a lower lip of the consumer while drinking the liquid beverage when the beverage container is tilted from vertical.
Description
- The present disclosure relates to beverage containers and, more particularly, to beverage containers having improved venting and consumer consumption structures.
- Containers and cans are ubiquitous throughout the beverage industry. Beverage cans typically include a cylindrical body having a lid. The lid includes a score line or lines defining a tear panel which is opened when a riveted tab pushes in the tear panel. When the consumer raises the back of the tab, the tab is forced against the tear panel to create a primary opening of the can.
- The primary or pour opening in such designs is used to allow the liquid in the can to exit from the volume of the cylindrical body. Additionally, the pour opening allows ambient air to enter the volume and replace the exiting liquid. This dual use of the primary opening may interfere with smooth pouring of the liquid content. For example, the upper lip or tongue of the consumer may overlie the primary opening in a manner that prevents proper venting. There have been attempts, mostly unsuccessful, to facilitate proper venting. To this end, some beverage cans include a second vent opening or tear panel and an apparatus for opening both the pour and vent tear panels.
- Current beverage can designs may also create physical interferences when the beverage is directly consumed from the container. Sometimes, the rim of the container and structures used to tear the pour opening May press against the consumer's nose when the beverage can is tilted for consumption. Further, the container must often be tilted to a large angle to consume the remaining beverage in the final stages of consumption. This may be difficult for individuals having neck or back pain.
- An improved beverage container is disclosed. In a first general example, the beverage container includes a cylindrical body defining a volume configured to hold a liquid beverage, where the beverage container also includes a neck having at least one slanted sidewall extending inwardly from and about a circumference of a first end of the cylindrical body. The neck has a first end sealed with the first end of the cylindrical body. The beverage container also includes a lid sealed with a second end of the neck, where the lid has a top planar portion with one or more score lines. The one or more score lines define a primary opening when ruptured that is dimensioned to provide a flow of the liquid beverage to a consumer when the beverage container is tilted from vertical. The beverage container also includes a lip relief extending inward and only partially circumventing an area of the neck. The lip relief is aligned with the primary opening and is dimensioned to accept a lower lip of the consumer while drinking the liquid beverage when the beverage container is tilted from vertical.
- Implementations of this example may include one or more of the following features. The beverage container where the lip relief is formed as a single recess in the slanted sidewall of the neck. The beverage container where the lip relief has a first thickness and the neck has a second thickness, where the first thickness and the second thickness are substantially the same. The beverage container where the lip relief is formed as a single recess in both the neck and the first end of the cylindrical body. The beverage container where the lip relief is formed as a recess having an upper region defined by a first arcuate portion and a lower region defined by a second arcuate portion, where the first arcuate portion has a radius less than a radius of the second arcuate portion. The beverage container where the lip relief includes an oblong recess having an axis of symmetry that is substantially perpendicular to a radial axis of the primary opening formed when the one or more score lines is ruptured. The beverage container where the one or more score lines defines a generally oval opening when ruptured, where the generally oval opening has a radial axis of symmetry that is generally perpendicular to an axis of symmetry of the lip relief.

FIG. 1 is a perspective view of one example of abeverage container 10 withFIGS. 2-6 illustrating various examples and/or modifications of thebeverage container 10. Thebeverage container 10 may be formed from a metal (such as aluminum, steel, tin, etc.) a polymer, or any other rigid material suitable to hold a liquid beverage. For this description, thebeverage container 10 is assumed to be formed from aluminum. - As shown in
FIG. 1 , thebeverage container 10 includes acylindrical body 20 defining a volume 25 (seeFIG. 4 ) configured to hold a liquid beverage. Aneck 30 having at least oneslanted sidewall 40 extends inwardly from and about a circumference of afirst end 50 of thecylindrical body 20. In this example, theneck 30 has a frustoconical shape. Afirst end 60 of theneck 30 is sealed, in a liquid-type manner, with thefirst end 50 of thecylindrical body 20. - The
beverage container 10 also includes alid 70 that is sealed, in a liquid-type manner, with asecond end 80 of theneck 30. Thelid 70 may engage thesecond end 80 at anupstanding rim 90 having sidewalls defining edges of aplanar portion 100. Theplanar portion 100 includes one or more score lines 110. When a consumer raises rivetedtab 120, theplanar portion 100 is ruptured along the one ormore score lines 110 to form aprimary opening 130 that is dimensioned to provide a flow of the liquid beverage from thevolume 25 of thecylindrical body 20 to the consumer when thebeverage container 10 is tilted from vertical. - The
beverage container 10 further includes alip relief 140. Thelip relief 140 extends inward of theneck 30 and only partially circumvents an area of theneck 30. As shown, thelip relief 140 is aligned with theprimary opening 130 when thescore lines 110 are ruptured. Thelip relief 140 is dimensioned to accept a lower lip of the consumer while drinking the liquid beverage and may have smoothed edges so as not to cut or otherwise irritate the lower lip. When the lower lip of the consumer engages thelip relief 140, the top lip of the consumer is pulled slightly rearward. The dimensions may be selected to facilitate creating a larger venting area for theprimary opening 130 than would otherwise occur without thelip relief 140. Further, thelip relief 140 may be dimensioned so that the consumer need not tilt their head back as far from vertical when drinking the last portions of the liquid beverage from thebeverage container 10 than would otherwise be needed without thelip relief 140. - The
lip relief 140 may be formed as a single recess that is constrained to the slanted sidewall of theneck 30. Alternatively, as shown inFIG. 5 , thelip relief 140 may be formed as a recess in both the slanted sidewall of theneck 30 and thefirst end 50 of thecylindrical body 20. - Various shapes may be used for the
lip relief 140. For example, thelip relief 140 may be formed as a recess having an upper region defined by a firstarcuate portion 150 and a lower region defined by a secondarcuate portion 160. Thearcuate portions arcuate portion 150 may be less than the radius of the secondarcuate portion 160. Optionally, thelip relief 140 may be formed as an oblong recess that includes aflow channel number 170 to direct fluid to the upper portion of the lower lip of the consumer while drinking the liquid beverage. - As noted, the
lip relief 140 may be aligned with theprimary opening 130 that is formed when thescore lines 110 are ruptured. In one example, thelip relief 140 may be in the form of an oblong indentation having an axis ofsymmetry 180 that is aligned with aradial axis 190 of theprimary opening 130. Further, in another example, theradial axis 190 of theprimary opening 130 may be an axis of symmetry of theprimary opening 130. Still further, theradial axis 190 may be generally perpendicular (although possibly located on separate planes) with the axis ofsymmetry 180. -
FIG. 4 shows one example of a cross-section of thebeverage container 10 through line 4-4 ofFIG. 3 . In this example, the material forming thelip relief 140 has a first thickness and the material forming theneck 30 has a second thickness. The first thickness and the second thickness may be substantially the same as one another to ensure robustness of the combinedneck 30 andlip relief 140 during manufacturing, packaging, transportation, storage, and consumption. Although other beverage container manufacturing processes may be used, one manner in which similar thicknesses for theneck 30 andlip relief 140 may be formed is shown in the necking process discussed below in connection withFIGS. 7-10 . - Various venting structures may be combined with the
lip relief 140 of thebeverage container 10. Several such venting structures are shown inFIG. 6 . In accordance with one venting structure, the rivetedtab 120 is use to rupture a first set ofscore lines 195 to provide theprimary opening 130. The rivetedtab 120 is then restored to its initial position and rotated to the position shown inFIG. 6 . In this position, the rivetedtab 120 may again be raised to rupture a secondary set ofscore lines 200 to enhance the size of theprimary opening 130. Additionally, or in the alternative, one ormore score lines 210, displaced from theprimary opening 130, may be punctured to provide a vent opening. - The manufacturing and filling of the
beverage container 10 may be executed in several manners. Frequently, however, a beverage container base is formed separately from a lid. As noted, the lid applied to the beverage container base includes one or more score lines defining a primary flow opening when the one or more score lines are ruptured. -
FIG. 7 throughFIG. 10 show one example of a process that may form a neck and lip relief in a beverage container base, where the container base may be filled and sealed with a lid in later manufacturing operations. Forming a neck is often done in containers made out of steel, aluminum, or tin and is performed in several stages to minimize the appearance of wrinkles, fractures, or both. In the manufacturer of aluminum beverage containers, the necking process may be carried out after the container has been drawn in several operations from a blank. - Each stage of the necking operation may include the operations shown in
FIG. 7 throughFIG. 10 . InFIG. 7 , a blank has been drawn to form and initialcylindrical cup 220 that is fed beneath apunch 230 and die 240 that have been retracted to an initial state. As shown, thepunch 230 includes arecess 235 that aligns with acorresponding protrusion 245 of the die 240 to form thelip relief 140 in theneck 30 during the necking operations. InFIG. 8 , thecylindrical cup 220 is pushed toward thedie 230 by a pushingtool 250 to align it with thepunch 230. InFIG. 9 , thecylindrical cup 220 and punch 230 are pushed together into thedie 240 to form aneck 30 having thelip relief 140. InFIG. 10 , the pushingtool 250 and thepunch 230 are returned to their initial positions. These processes may be repeated, if desired, using progressively smaller diameters of punches and dies to obtain the final desired shape. As such, theneck 30 and thelip relief 140 need not be formed in a single sequence of operations. - Once the final desired shape is reached, the resulting container base may be filled and sealed with the lid, where the lid is sealed with the container base so that the score lines forming the primary opening are aligned with the lip recess in the container base.
- In accordance with another processing example, the
neck 30 with thelip relief 140 may be formed in a roller press necking operation in which the pressing tools have corresponding protrusions and recesses in the areas in which the lip relief is to be formed. - It will be appreciated that the foregoing disclosure provides examples of at least one beverage container that may implement the present invention. However, it is contemplated that other implementations of the beverage container and manufacturing processes may differ in detail from the foregoing examples. All references to the examples thereof are intended to reference the particular example being discussed at that point and are not intended to imply any limitation as to the scope of the invention more generally. All language of distinction and disparagement regarding certain features is intended to indicate a lack of preference for those features, but not to exclude such from the scope of the invention entirely unless otherwise indicated.
