BOTTLE THROWAWAY CROWN CAP REMOVER Filed Jan. 7, 1955 INVENTOR C'arl/ Jaluniiz ATTORNEY SlilS lg? BOTTLE THROWAWAY CROWN CAP REMOVER Carl Schmitz, Guttenberg, N. J.

Application January 7, 1953, Serial No. 330,029

'1 Claim. (Cl. 215-46) This invention relates to a bottle throwaway crown cap remover and to a combination beverage bottle crown cap and throwaway remover and has for an object to provide a throwaway crown cap remover for use in connection with a conventional beverage bottle or container and a conventional crown cap, and particularly to provide a throwaway bottle cap remover that is so inexpensive that it may be placed over the lip of the beverage bottle and be supported on the shoulder therebelow without interfering in any way with the normal filling or capping of the bottle, will not interfere with conventional machinery used in the filling and in the capping of the bottle, and when used to remove the crown cap, may be left in position if the crown cap is reused for temporary sealing of the bottle with part of the contents still remaining therein, and may be finally discarded and thrown away at the same time that the crown cap is discarded and thrown away.

A further object of this invention is to provide a throwaway remover for a crown cap, which may be made inexpensively from suitable metal by a single stamping and bending process, and which may be placed into operative position on the beverage bottle by simply dropping it over the lip of the bottle, either before or after the contents has been placed in the bottle, and, of course, before the crown cap has been placed on the lip of the bottle to seal it in the conventional manner by the conventional machinery.

A further object of this invention is to provide an improved crown cap remover, which enables the bottle to be opened with one hand by simply placing one hand around the neck of the bottle and placing ones thumb beneath a projecting tongue of the opener and exerting upward pressure, whereupon the opener or remover will lift the crown cap off of the lip of the bottle.

With the foregoing and other objects in view, this invention comprises the combination, construction and arrangement of parts hereinafter set forth, claimed and disclosed in the accompanying drawings, wherein:

Fig. l is a top plan view of the throwaway remover per se.

Fig. 2 is a side edge view of Fig. 1.

Fig. 3 is a fragmentary view of a bottle and crown cap thereon with this invention in position thereon.

Fig. 4 is a side plan view of the remover in operation.

There is shown at the throwaway bottle cap remover of this invention consisting of a flat annular ring 11 having a projecting tongue 12 at one side thereof.

The tongue 12 and the adjacent segment portion 13 of the annular ring 11 is bent upwardly, as shown, and a segment portion 14 diametrically opposite the segment portion 13 is bent downwardly, as shown. The inner diameter of the annular ring 11 is sufliciently greater than the diameter of the bottle lip 15 that it will pass easily thereover in either direction, and it is also lesser than the maximum diameter of the crimped flange 16 of the crown bottle cap 17. Also, the inner diameter of the ring 11 is greater than the diameter of the bulge 2 or shoulder 18 of the beverage bottle 20, which is located below the recess or neck lip 21 into which the flange 16 is crimp'ed when sealing the cap 17 for closing the bottle 20. I

As will be apparent from Fig. 3, the relationship of the inner diameter of the opening in the annular ring 11 is such to the diameter of the bulge or shoulder 18 that when the bottle cap 17 is secured by its crimped flange 16 on the lip 11, the top surface of the fiat ring 11 will be spaced slightly below the bottom edge of the crimped flange 16, thus, avoiding any possible interference with either the filling of the bottle 20 by conventional machinery, or with the operation of the normal capping machine in crimping the flange 16 of the cap 17 into position after the remover 10 has been dropped over the lip 15 on to the shoulder 18.

In addition to the advantage of having a bottle opener ready in operative position when the bottle 20 is to be opened, thus, eliminating the necessity for any other bottle opener, this invention has the advantage of providing easy one hand operation, thus, leaving the other hand available for holding a glass or cup into which the contents of the bottle 20 are to be poured.

As shown in Fig. 4, the bottle 20 is grasped in ones hand 21 by placing the fingers 22 about the bottle and placing the thumb 23 just below the projecting remover tongue 12 and exerting an upward pressure therebeneath. This has the effect of causing the bent down segment portion 14 to act as a fulcrum on the adjacent portion of the bulge or shoulder 18 and of the projecting tongue 12 to act as a leverage handle and exert a lifting force under the adjacent portion of the crimped flange 16 of the cap 17, causing this adjacent portion 16 to yield sufficiently to permit the bottle cap 17 to be lifted and removed from the bottle 20. If the entire contents of the bottle 20 are immediately removed, then, the cap remover 10 of this invention may be discarded along with the cap 17, but if part of the contents are still left in the bottle 20, and the cap 17 is used for temporary rescaling, then the remover 10 will be left in position when the cap 1'7 is placed temporarily back in position for re-use until the contents have been entirely dispensed, and then, both cap 17 and remover 10 may be thrown away and discarded.

Due to the fact that the lifting force is spread over a substantial area of the crimped flange 16 instead of being concentrated in one point, as happens with many conventional openers, the cap 17 is distorted to a minimum amount in being initially opened, and hence, is more eflective as a temporary reseal than is possible when the cap has been opened by a conventional opener, which concentrates its force at substantially one point.

While the device has been shown and the structure described in detail, it is obvious that this invention is not to be considered as being limited to the exact form disclosed, and that changes in detail and construction may be made therein within the scope of what is claimed, without departing from the spirit of this invention.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

In combination with a bottle having a bead adjacent its top, a flange extending above said bead, and a crimped cap secured about said flange, a disposable opener loosely positioned between said bead and said cap extending about said flange, said opener comprising a substantially flat annular ring encircling said flange, a segment portion of said ring bent upwardly at an obtuse angle to the body of said ring, a thumb engageable tongue having a leverage point adapted to bear against said cap, said tongue being integral with said segment portion and coplanar therewith, a second segment portion of said ring directly opposite said tongue being bent downwardly 3 at an obtuse angle from the plane of said ring to form a fulcrum adapted to bear against said bead when said tongue is pressed upwardly to lift said cap from said flange.
