Definitions

  • the present invention relates generally to closures for beverage containers and the manner of accessing the beverage content of such containers.
  • the beverage containers may be metal containers or cans that may be either steel coated or aluminum.
  • the present invention relates to a drinking spout and closure combination that can be added to such beverage containers to improve and enhance one's ability to drink directly from the beverage container.
  • the present invention utilizes the geometry of the beverage container neck and neck opening to enable a snap-on assembly of the drinking spout directly to the container. This then provides the smooth plastic of the spout as the point of contact with the consumer.
  • a related improvement offered by the present invention is the ability to reseal the container after initial opening. This keeps any unused or unconsumed portions of the beverage contents fresh and minimizes oxygen ingress.
  • While the present invention is not specifically directed to pull-tab soft drink cans, there are a variety of other beverage containers that are of a metal can construction.
  • metal can beverage containers When such metal can beverage containers are opened, the consumer likely has a somewhat unpleasant experience whenever drinking directly from the metal container. Unless the beverage contents are poured from the metal container into another container, such as a drinking glass or cup, the consumer must drink directly from the metal container, causing the lips to contact the exposed metal edge of the opened beverage container.
  • Document US 5,071,042 relates to an adapter that provides a bottle like spout for an aluminium beverage can.
  • the adapter is arranged to releasably engage the rim of the beverage can.
  • Document DE 7517310 relates to a cap for a bottle.
  • the cap has a lower section and an upper section with a tab that can be separated from the lower section.
  • a drinking spout and closure combination for a beverage container that includes a neck defining an opening, said neck having an enlarged annular lip said combination comprising:
  • One object of the present invention is to provide an improved drinking spout and closure combination for a beverage container.
  • Container 20 includes a hollow body 23 tapering into a smaller neck 24 defining an opening 25 for filling the container body 23 with a selected beverage. Opening 25 later functions for consuming or dispensing the beverage contents. Without the benefit of the present invention, the consumer would typically drink directly from opening 25, with the lips of the consumer contacting the metal neck 24 and/or upper edge 26. While one option is to pour some or all of the beverage contents into another container, such as a glass or cup, one aspect of the present invention focuses on improving the experience for the consumer when drinking directly from the container. This improvement is provided by fitting the neck opening with the plastic drinking spout 21.
  • drinking spout 21 is a unitary, injection molded plastic component that snaps onto neck opening 25 so as to be securely retained thereon with a tightly sealed annular interface.
  • Spout 21 includes an annular body 30, an offset, lower annular wall 31, and an offset, outer annular wall 32.
  • Lower annular wall 31 is spaced apart from and is radially inwardly of outer annular wall 32.
  • Body 30 includes an annular lip 33 that is shaped, contoured, and finished so as to provide a smooth and comfortable drinking surface for the lips of the consumer.
  • Annular lip 33 is enlarged in terms of the outside diameter of body 30 so as to protrude radially outwardly as illustrated in FIGS. 2-4 . This enlarged annular lip 33 not only provides a comfortable drinking surface and shape for the lips of the consumer, but also provides a structurally effective way to receive closure 22 with a secure snap-fit assembly.
  • the axial length of body 30 from lip 33 to offset radial shelf 34 is sufficient for the lower lip of the consumer to be positioned and compressed against body 30 without interfering with shelf 34 or wall 32.
  • the smooth and curved surface of body 30 in this axial region contributes to the ease and comfort of using spout 21 for drinking directly from beverage container 20.
  • Lower annular wall 31 is constructed and arranged with a radially outwardly protruding or extending annular ridge 37 and an axially adjacent concave recess 38.
  • outer annular wall 32 is constructed and arranged with a radially inwardly protruding or extending annular ridge 39 that is generally radially aligned with ridge 37.
  • the open annular channel 40 defined by walls 31 and 32 in cooperation with shelf 34, is constructed and arranged to receive the upper portion of neck 24 with a snap-on fit and assembly.
  • neck 24 extends axially in an upward direction, terminating at annular lip 41.
  • Annular lip 41 is considered enlarged in terms of the outside diameter surface of neck 24.
  • enlarged annular lip 41 extends radially outwardly beyond the outer surface of neck 24 so as to provide an undersurface recess adjacent lip 41 to facilitate the snap-on assembly of spout 21.
  • the opposed ridges 37 and 39 can be viewed as providing a clamping action onto neck 24, ridge 37 further provides a sealing interface against the inner cylindrical surface of neck 24, as annular wall 31 slides down inside of neck opening 25.
  • Cooperating ridge 39 protrudes radially inwardly below lip 41 such that there is a snap-fit or snap-on assembly of the spout 21 by means of channel 40 onto neck 24 by utilizing lip 41.
  • the inwardly directed taper of lower portion 42 of wall 31 provides an easy initial or starting insertion for spout 21 into opening 25. This then permits the relative sizing of spout 21 relative to neck opening 25 to be designed for some degree of interference so as to establish a sealed annular interface between ridge 37 and the inside surface of opening 25. As spout 21 is advanced axially downwardly, into and onto neck 24 and lip 41, the fit of wall 31 into opening 25 becomes tighter. Ultimately, ridge 37 provides a compressed, tight seal against the inner surface of neck 24. At or about the same time, ridge 39 applies a tight sealing pressure against the outer surface of neck 24 beneath lip 41. Ridge 39 projects radially inwardly far enough to function both for a tight seal against liquid leakage and for a secure, snap-fit assembly of the spout 21 onto the neck 24 of container 20.
  • Closure 22 is a unitary, injection molded plastic component that includes a generally circular upper wall 45 that is surrounded by an axially depending, annular outer wall 46.
  • a radially inner wall 47 also annular and axially depending, is substantially uniformly spaced from the outer wall 46 so that in combination with upper wall 45, an annular channel 48 is defined.
  • the inner surface 49 of outer wall 46 includes an annular, raised ridge 50 that extends or protrudes radially inwardly toward the inner wall 47.
  • the lower tip of inner wall 47 is tapered so that it inserts easily into the open interior of spout 21 as the enlarged annular lip 33 of spout 21 fits into annular channel 48.
  • outer surface 54 of outer wall 46 is contoured with axially-extending (recessed) grooves 55 causing the alternating portions 56 of the outer surface 54 to have the appearance of axially-extending ribs.
  • a weakened score line groove 57 extends from lower edge 58 upwardly to top surface 59 and around a portion of upper wall 45 in a part-circular path, see FIG. 6 .
  • a unitary pull tab 60 as part of outer wall 46, extends downwardly from the lower edge 58 and curves outwardly, as illustrated in FTGS. 5 and 7.
  • pull tab 60 positions tip 61 outwardly away from closure 22 as well as outwardly away from drinking spout 21 and container 20, thus enabling adequate clearance for any easy grasping of pull tab 60 by the index finger and thumb of the user for removal of closure 22. What actually occurs is that the upward and outward pulling on pull tab 60 causes the weakened score line for groove 57 to fracture or sever, thereby permitting the outer portion of outer wall 46 to separate from the remainder of closure 22. Once the closed circumferential/cylindrical form of outer wall 46 is broken open or partially severed by the use of pull tab 60, the remainder of outer wall 46 is able to be freed from spout 21.
  • Annular channel 48 is constructed and arranged to receive annular lip 33 with a secure, leak-free fit.
  • Channel 48 is open at its lower end 65 and closed at the opposite end by wall 45. Open end 65 has a reduced radial width due to the inwardly extending raised ridge 50. This construction permits ridge 50 to lock below lip 33 for a secure, snap-on interfit between the drinking spout 21 and closure 22. It will be seen that the opening shape of channel 48 at the closed end has a shape that closely corresponds to the shape of the enlarged, annular lip 33, helping to ensure the leak-free, snap-on interfit.
  • the inner annular wall 47 is constructed and arranged for a slight interference fit against the inner cylindrical surface 66 of body 30. Due to the plastic construction of closure 22 and drinking spout 21, some slight flexibility is inherent in both parts and the interfering surfaces of wall 47 and body 30. This creates a secondary seal around the interior of the drinking spout 21 to prevent any liquid leakage from beverage container 20.
  • the drinking spout 21 is securely snapped onto the neck 24 of container 20.
  • the closure 22 is securely snapped onto drinking spout 21.
  • the pull tab 60 is lifted or pulled upwardly and outwardly, causing portion 67 to separate from the remainder of closure 22 as the thin web 68 of material at the base of the score line groove is torn. The tearing of the thin web 68 up the outer wall and around a portion of the upper wall pulls section 67 out of engagement with drinking spout 21.
  • closure 22 This in turns allows the closure 22 to be removed from the drinking spout 21 so that the consumer is able to drink directly from the spout 21 in order to consume a portion of the beverage contents in container 20.
  • the closure 22 can be fitted back onto drinking spout 21 in order to reseal the container 20 whenever some of the beverage remains in the container.
  • closure 22 enables it to be forcibly snapped onto drinking spout 21 by a downward axial force. Removal of closure 22, without the use of (i.e., tearing) the score line groove 57 would be difficult to accomplish and unlikely without destroying the closure. However, once the outer wall 46 is segmented by tearing through web 68 so that the outer portion 67 is separated from the remainder of the closure, the free ends of the outer wall can be easily pulled apart or spread apart and thereafter the closure 22. is easily pulled off of drinking spout 21.
  • the consumer can access the contents of container 20 by comfortably and easily drinking directly from spout 21. If the beverage contents of the container are not consumed after initial opening, the design of the present invention allows the closure 22 to be reapplied to spout 21. As the illustrated structures would denote, the inner wall 47 can be reinserted into the neck opening 25 in order to reseal the container 20 closed. This removal and replacement cycle for closure 22 can be repeated as often as necessary until the beverage contents are consumed. At each time the closure is removed, the smooth, rounded lip 33 of drinking spout 21 is exposed, providing the consumer with an easy, comfortable, and sanitary way to drink directly from the beverage container 20.
  • Suitable plastics for the injection molding of drinking spout 21 and of closure 22 include, but are not limited to, polypropylene, high density polyethylene, low density polyethylene, and polyethylene terephtalate. Since the expected use for the present invention is with metal beverage containers and carbonated beverages, it is desirable to include a barrier to protect the contents from oxygen ingress. As described herein, the drinking spout 21 is constructed and arranged to accept an aluminum foil seal. This constitutes one type of suitable barrier that is effective to protect the beverage contents from oxygen ingress.
  • Closure 22 is constructed and arranged to accept a liner in order to seal in pressure. The closure is also able to be molded with a barrier.
  • a drinking spout 21 is used in cooperation with a closure 22 in order to convert a beverage container 20 into a structure that provides for safe and comfortable drinking of the container contents.
  • the closure allows the container to be reclosed in the event a portion of the container contents remain after initial opening.
  • the drinking spout 21 is configured so as to snap into and onto the neck finish of the container, thereby converting the container into a structure for comfortable drinking directly from the spout.
  • the unitary, molded plastic drinking spout 80 has an annular lower portion 81 that is constructed and arranged the same as the lower portion of drinking spout 21 such that drinking spout 80 is constructed and arranged to snap onto neck 24 of container 20.
  • drinking spout 80 includes a lower annular wall 31, an outer annular wall 32, a radial shelf 34, an annular ridge 37, a concave recess 38, an annular ridge 39, an annular channel 40, and a lower portion 42.
  • the upper portion of drinking spout 80 includes a generally cylindrical body 82 that is externally threaded and terminates in an upper annular lip 83 that is shaped, contoured, and finished so as to provide a smooth and comfortable drinking surface for the lips of the consumer.
  • the external threads 84 are used for the assembly of screw-on closing cap 85 (see FIGS. 10 and 11 ).
  • Closing cap 85 is an annular, generally cylindrical structure with an internally-threaded sidewall 86 and a closing top panel 87.
  • closing cap 85 is a unitary, molded plastic component.
  • the outer surface 88 of sidewall 86 is formed with a plurality of axially-extending shallow grooves 89. Grooves 89 provide a gripping surface for ease in threading cap 85 onto drinking spout 80 and for removing cap 85 from drinking spout 80.
  • FIGS. 12-18 another embodiment of the present invention is illustrated.
  • This embodiment includes a unitary, molded plastic drinking spout 100 with a lug finish 101 as part of the upper body 102.
  • the second component is the unitary, molded plastic lug closure 103 that assembles onto drinking spout 100 to close the open end 104.
  • the assembly of closure 103 onto drinking spout 100 is illustrated in FIGS. 17 and 18 .
  • Drinking spout 100 includes an annular lower portion 105 that is constructed and arranged to snap onto the neck of a container, similar to container 20.
  • the lower portion 105 is configured slightly different from the lower portion 81 and the lower portion of drinking spout 21.
  • Lower portion 105 includes a lower annular wall 106, an outer annular wall 107, a connecting radial shelf 108, an inner annular ridge 109, a concave recess shaped as an annular channel 110, an outer annular ridge 111, an annular channel 112, and an annular lower portion 113.
  • This structure enables the drinking spout 100 to easily and reliably snap onto the neck finish of a corresponding container.
  • the upper cylindrical body 82 includes an annular, circumferential stop 116, an upper lip 117, and three lug rails 118 positioned between the stop 116 and the upper lip 117.
  • the upper lip 117 is shaped, contoured, and finished so as to provide a smooth and comfortable drinking surface for the lips of the consumer.
  • Each lug rail 118 is shaped into two sections. An upper, near horizontal section 118a is connected to a lower, inclined ramp section 118b. The lower end of each section 118b is integral with stop 116.
  • the lug closure 103 includes a closed upper panel 121, a surrounding sidewall 122, and three equally-spaced lugs 123 on the inner surface of lug closure 103.
  • Each lug 123 is sized, shaped, and spaced apart to fit beneath a corresponding one of the lug rails 118 when closure 103 is placed onto drinking spout 100. Initially, closure 103 will not seat properly on drinking spout 100 until the closure is turned such that each lug 123 is positioned between each lug rail 118. This allows the inner surface of upper panel 121 to rest on the upper edge of lip 117.
  • closure 103 is turned in a clockwise direction relative to drinking spout 100, the lugs 123 ride beneath the rails 118 and, as the ramp sections 118b are encountered, the continued clockwise rotation of closure 103 draws the closure down tightly against the upper edge of lip 117. This tight assembly thereby establishes a securely closed container by way of drinking spout 100.
  • the lug closure 103 is simply turned in a counter clockwise direction, allowing the lugs 123 to ride along the rails 118 until such time as the lugs are positioned between adjacent rails so that the lug closure can be lifted off of the drinking spout 100.
