Description
3~
This application relates to a combination beverage container and cap remover.
BACRGROUND OF T~ INV~TION
There has recently been a move in some aspects of the beverage indus-try, particularly the brewed alcoholic beverage industry, to replace traditional crown caps on beer and the like bottles by caps which are of the threaded twist off type. The most common of the twist off caps are in fact a combination oE
the traditional crown caps with an additional twist off feature.
The user therefore has the option of twisting -the cap off on threads provided on the bottle or prying it off using a traditional crown cap opener.
Clearly, a major reason for the introduction of the combination twist/crown cap is to do away with the necessity for having a traditional crown cap opener available.
A number of factors have lead to difficulties with the combination caps. In order to maintain the required pressure in the bottles, the caps must fit very tightly and must not be dislodgeable by normal handling. At the same time, the caps also include the crimped edges characteristic of crown caps. The result is that in some cases the combination caps require a considerable effort to twist off, and many users either do not have sufficient stength to apply to the small surface of the cap or are reluctant to apply the necessary pressure because of the risk of injury occasioned by the sharp crimped edges. Frequent cutting, tearing and scraping of the fingers results from the use of these caps.
There is therefore a need -to provide a means for removal of the new combination caps which will avoid injury to the hands and will also avoid the requirement for the presence of a separate opener.
It is to this problem that the present invention is directed.
PRIOR ART
Various types of beverage container opener combinations have been proposed, but none is aimed at nor adequate for the present problem.
Grunwald U.S. Patent 2,745,301, issued May 15, 1956, illustrates one such early bottle/opener combination. The subject matter of this patent exhibits many problems. For example, the prying action across the bar concentrates the force applied against the bar and results in breakage. The depth of depression in the bottom of the container again necessitated by the prying action is substantial. The extra size and required strengthening in this case mitigate agains-t its use.
Martinmaas U.S. Patent 3,236,126, issued February 22, 1966, provides a combination similar to that of Grunwald. In this case the container is specially shaped to form a fulcrum for the prying action in removing the cap. The prying action requires the levering of one bottle against the other. Again there is clear danger of chipping and breakage where -the crown cap contacts the glass, and in the contact between -the two bottles.
Neither reference suggests usage with a combination twist/crown cap.
SUk~lARY OF T~E INVENTION
It has now been discovered that the force required to remove a combination twist/crown cap can be spread about a relatively fragile opener in such a way as to lessen the stress on any single part of the opener and thereby avoid chipping, breakage and the like.
Accordingly, the invention provides a beverage container comprising a continuous body section, a neck section integral with the body section and terminating in an e~ternally threaded section adapted to receive a combination twist/crown cap, a bottom section integral with the body section, the bottom section having an indented section integral therewith, and wherein the indented section is provided with a set of spaced profiled teeth in a circular arrangement adapted to engage indentations in the crimped edges of a combination twist/crown cap.

BRIEF DESCRIPTION OF T~E DRAWINGS
In drawings which illustrate embodiments of the invention, FIGURE 1 is a side elevation view of a container according to the invention;
FIGURE 2 is a bottom plan view of the container illustrating a twist/crown cap in the bottom of -the container;
FIGURE 3 illustrates a tooth ring for use with the invention;
FIGURE ~ is a section along line IV-IV of FIGURE 3; and FIGURE 5 illustrates the manner of use of the container as an opener.
While the invention will be described in conjunction with illustrated embodiments, it will be understood that it is not intended to limit the invention to such embodiments. On the contrary, it is intended to cover all alternatives, modifications and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
DETAILED DESCRIPTI~N OF T~E EMBODIMENTS
In the following description, similar features in the drawings have been given similar reference numerals.
FIGURE 1 illustrates a beverage container comprising a bottle 10 having an externally threaded section 12 at the top 22 ,5~
thereoE. Associated with the bottle 10 is a combination twist/crown cap 14. When applied to the bottle 10 as best illustrated in Figure 5, the edge 16 of the cap 14 maintains a crimped configuration comprising protrusions 18 and inden-tations 20.
The cap 14 may be removed from bottle 10 by prying the crimped edge 16 outwardly from the threaded top 12 of the bottle using a conventional opener or by twisting the cap against the threads 24 of threaded section 12.
In the latter case, the pressure required to loosen the cap is considerable and may frequently result in injury to the hand.
To avoid this problem the bottle 10 is here provided with an opener 26 recessed in the bottom 28 of the bottle. Thus the bottle is provided in the bottom with an indentation 30 which can take various configurations, depending on whether some or all of the opener 26 is integral with bottom 28 or comprises an insert secured within indentation 30.
As illustrated in FIGURES 1 and 2~ the teeth 32 are molded integrally with the bottom 28 of the bottle 10 to form a set each of which presents a cylindrical outer side 34. The teeth 32 preferably extend from top edge 36 to bottom edge 38 of i.ndentation 30. Indentation 30 preferably has a depth "d"
approximating the height of cap 14. As well, -the teeth 32 are preferably curved longitudinally to match the normally curved edge from top 40 to bottom 42 of the crimped edge 16 of cap 14.
~5~
The number, size and arrangement of tee-th can be varied as felt necessary to balance the factors affecting opening. For example, a greater number of teeth will distribute opening force over a greater area but will be somewhat more difficult to place over a cap. For standard sized caps 14, it has been Eound preferable to provide seven teeth 32 evenly distributed about the indentation 30.
FIGURES 3, 4, and 5 illustrate a variation in which the indentation 30 has a basically cylindrical configuration and a toothed ring 44 is secured within the indentation. FIGURES 4 and 5 illustrate a variation in the shape of the teeth 32 in which the teeth 32 are of truncated pyramindal shape. The outer face 46 of these teeth may be further profiled for easy approach to the indentations 20 of the cap 14, and the body of teeth correspondingly modified.
Various other tooth designs can be proposed which would be entirely suitable.
The ring 44 may be constructed of any suitable material, such as metal or plastic, but a tough resilient plastic is preferred. Plastics are readily available which will withstand repeated use and, as well, nandling, cleaning, and the like operations between uses.
Similarly, various techniques may be employed for securing the ring 44 into the indentation 30. These include the use of adhesives, and press or snap fits.
I'he manner of use of the invention is to invert the combination twist/crown cap of a bottle to be opened into the opener so that the teeth 32 engage the crimped edge 16 of the cap. Relative twisting of the bottles then results in easy removal of the cap.
Thus it is apparent that there has been provided in accordance with the invention a combination beverage container and cap remover that fully satisfies the objects, aims and advantages set forth above. While the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications and variations as fall within the spirit and broad scope of the invention.
