Primary Examiner-Al Lawrence Smith Assistant Examiner-Roscoe V. Parker  ABSTRACT This bottle cap remover includes a unitary body having an opening adapted to receive a bottle cap of the type having circumferential ribs and grooves. The opening defines a side wall and an end closure wall, the side wall including a corresponding number of ribs and grooves compatibly shaped to suit the ribs and grooves of the cap. The closure wall is engageable by the cap to facilitate the cap removal, which is effectuated by twisting the body.
1 Claim, 6 Drawing Figures 1 BOTTLE CAP REMOVER This invention relates generally to an improved bottle cap remover and more particularly to a remover for use with twist-off bottle caps.
In the past attempts have been made to provide means of assisting the removal of the caps of bottles and jars, which are difficult to remove by hand alone. The prior art includes examples of rubber rings particularly adapted for removing jar tops. Such removers typically include either a roughened inner surface or provide a plurality of yieldable, flexible projections. In each case the removal action relies on surface friction contact between the device and the jar top. Other devices in the art include an inflexible, open conical ring of metal having inner grooves to assist in gripping a relatively smooth cap.
The known prior art does not reveal a cap remover which is compatibly structured to mate with the cap to be removed.
SUMMARY OF THE INVENTION This bottle cap remover is so structured to provide mating elements engageable with the ribs of twist-off bottle caps to assist in the removal of such caps.
The remover is of unitary construction and can be adapted for use with the rib serrations of both beer bottle and soda bottle caps.
One species of the device is adapted to remove more than one type of cap and yet remains compact and easy to use.
The bottle cap remover comprises essentially a body including an opening receiving the cap and an arcuate side wall portion having a plurality of compatible ribs and grooves matable with the ribs and grooves of the cap. The body includes an abutment means transversely disposed of the side wall and engageable by the end wall of the cap. The body side wall portion is substantially annular and the ribs and grooves are evenly spaced circumferentially of the side wall portion and in a direction generally parallel with the annular wall axis.
The side wall portion includes an outer hand engageable gripping means and the gripping means includes a projecting lug by which additional leverage may be applied to the cap to be removed.
A second embodiment of the cap remover is adapted to suit more than one type of bottle cap and to this end includes a second row of circumferentially disposed ribs adjacently disposed of the first row and projecting radially inwardly a greater distance than said first row to receive a cap of smaller diameter than the cap operatively engageable by the first row. The second row of ribs defines an abutment means engageable by the first cap and the closure wall is engageable by the second cap.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of the bottle cap remover from the underside;
FIG. 2 is an exploded view illustrating the bottle cap remover in cross section;
FIG. 3 is a perspective view of a modified structure;
FIG. 4 is a view illustrating the modified structure in cross section and in use with one type of bottle cap;
FIG. 5 is a similar view of the bottle cap remover in use with a different type of bottle cap, and
FIG. 6 is an enlarged detail of the modified structure.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now by characters of reference to the drawing and first to FIGS. 1 and 2 it will be understood that the bottle cap remover includes a unitary, substantially cylindrical body molded from a relatively inflexible plastic material, such as polypropolene, or metal. The body 10 includes an opening 11 defined by a sidewall 12 and an end wall 13. A lug 14 projects radially outwardly from the side wall 12 and is apertured to suit a key chain 15. The side wall 12 is substantially annular in configuration and includes a plurality of alternating ribs and grooves 16 and 17 respectively circumferentially disposed and substantially evenly spaced about the inner surface of said side wall 12. The ribs and grooves are oriented in a direction substantially parallel with the axis of the annular side wall 12 but may be slightly tapered if desired. The outer surface of the side wall 12 is provided with a plurality of serrations generally indicated by numeral 18.
The embodiment illustrated in FIG. 2 is adapted to suit a bottle cap 20, having a circumferential side wall 21 and an integrally formed end closure wall 22, of the type commonly used on beer bottles, such as that indicated by numeral 23, which are provided with a helical thread 24 to permit the cap to be removed by twisting. This cap 20 is provided with 21 grooves and ribs 25 and 26 respectively. It will be understood that the ribs and grooves 16 and 17 provided on the inner surface of the side wall 12 correspond in number to the grooves and ribs 25 and 26 and are of a compatible shape.
The cap 20 is receivable within the opening 11 of the body 10 so that the ribs and grooves 16 and l7 of'said cap are mated with the grooves and ribs 25 and 26 of the body when the cap end wall 22 is engaged by the inside face 19 of the body end wall 13, said body end wall constituting an abutment means. By hand-gripping the body 10 and twisting said body and cap 20 together the cap is easily removed. The serrations 18 provide a suitable gripping surface and the projecting lug 14 provides additional leverage should such leverage be required.
The embodiment illustrated in FIGS. 3, 4, 5 and 6 is adapted to suit two bottle caps of different configuration and having different numbers of ribs and grooves. Preferably this embodiment is adapted to suit the beer bottle cap already described and a'bottle cap 50 of the type commonly used on soda bottles such as that indicated by numeral 53.
In order to accomplish this dual purpose the bottle cap remover includes a body 30 having an opening 31 defining a side wall 32 and a transverse end wall 33.
The side wall 32 is subsantially annular in configration and includes a first row 40 of alternating ribs and grooves 41 and 42 respectively, circumferentially disposed and substantially evenly spaced about the inner surface of said side wall 12. The side wall 32 also includes a second, adjacent, row 43 of ribs and grooves 44 and 45 respectively, which are likewise circumferentially disposed and substantially evenly spaced about the inner surface of said side wall 12. A lug 34 projects from the body and is apertured to suit a key chain 35.
The outer surface of the side wall 32 is provided with a plurality of serrations 36 to facilitate gripping.
The first row 40 provides ribs and grooves 41 and 42 which are adapted to suit the grooves and ribs 25 and 26 of the cap 20. As shown in FIGS. 4 and 5, the second row 43 is provided with ribs and grooves 44 and 45, which are adapted to suit a different cap as will be described. It will be observed that the ribs 44 of the second row 43 project radially inwardly of the ribs 41 of the first row 40 and the adjacent ends of said ribs 44 thereby provide an intermittent ledge, generally indicated by numeral 46, constituting an abutment means. As shown in FIG. 4, the cap 20 is receivable within the outer portion of the opening 31 of the body 30 so that the ribs and grooves 16 and 17 of said cap are mated with the grooves and ribs 41 and 42 of the body when the cap end wall 22 is engaged by the intermittent ledge 46.
As shown in FIG. the opening 31 is also adapted to receive a bottle cap 50 having a circumferential side wall 51 and an integrally formed end closure wall 52 of the type commonly used on soda bottles such as that indicated by numeral 53, which are provided with a helical thread (not shown) to permit the cap 50 to be removed by twisting. This cap 50 is provided with 40 grooves and ribs 54 and 55 respectively. It will be understood that the ribs and grooves 43 and 44 provided by-the second row 43 correspond in number and are compatibly shaped to suit the cap grooves and ribs 54 and 55 and that the diameter of the cap 50 in the vicinity of the grooves and ribs 54 and 55 is less than the diameter of the first, outer, row of ribs 41 to permit the cap 50 to be received into the opening 31.
The cap 50 is receivable within the opening 31 of the body 30 so that the grooves and ribs 54 and 55 of said cap are mated with the corresponding ribs and grooves 44 and 45 of the body when the cap end wall 52 is engaged by the inside face 39 of the body end wall 33.
The modified device is used in a manner similar to that described above for the first species with the exception that when used for removing cap 20, the cap is only partially inserted within the opening 31.
It will be understood that if desired the number of ribs and grooves in the first species can be adapted to suit a bottle cap having a different specific number of ribs and grooves than that shown. Thus, although the embodiment disclosed in FIGS. 1 and 2 includes 21 ribs and grooves and is therefore adapted to suit a conventional twist-off beer bottle cap' it could be provided with forty ribs and grooves and be of such a diameter that it would suit a conventional twist-off soda bottle cap.
FIGS. 3, 4 and 5 illustrate a bottle cap remover which is suitable for more than one type of cap, such caps having different numbers of ribs and grooves of different configuration. lt will be understood that the ribs adapted to suit the cap of larger diameter are disposed radially outwardly of, and closer to the mouth of the opening than, those adapted to suit the cap of smaller diameter.
