BOTTLE CAP.

APPLICATION FILED MAY 26, 1913.

BOTTLE-CA1.

Application filed May 26, 1913.

To all whom it may concern:

Be it known that 1, ROBERT Mo'r'sn BENorr AARONSON, a citizen of the French Republic, residing at Paris, in France, have invented certain new and useful Improvements in Bottle-Caps, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention has reference to an improved bottle cap tobe applied to any kind of receptacles whatsoever, such as bottles, jars, pots and the like, so as to permit of unstoppering the receptacle by hand without the assistance of any tool or instrument and of restoppering it hermetically with the same facility after extracting a portion of its contents.

I shall now describe my invention with reference to the accompanying drawing showing one form of construction by way of example, in which:

Figure 1 shows separately the various.

parts composing the cap. A is a metal capsule, the borders of which are threaded so as to screw on to C. B is a Washer contained in the capsule A. C is the metal socket threaded at its upper portion for receiving the capsule A. D is a split ring of square metal wire. E is a sealing band for assuring the inviolability of the contents of the receptacle to which the system is applied. Fig. 2 shows in section one method of fitting the system to a special bottle with a circular groove on the upper portion of the neck. Fig. 3 shows another method of fastening the system to an ordinary bottle, that is to say without groove, by means of the split ring D provided for this purpose. Fig. 4 is a top plan View of the sealing band.

This system of stoppering is employed in the following manner: Before stoppering the receptacle the capsule A with the washer B is screwed to the threaded portion of the socket C so as to form one piece, then by means of a special machine the socket is firmly fitted to the neck G of the receptacle by means of its lower portion by pressing the metal into the groove H provided for this purpose in the receptacle specially constructed for fitting with this stoppering system such as shown in Fig. 2; or by means of a metal ring or binding compressing the socket against the walls of the receptacle or otherwise. Fig. 2 also shows the special form of neck G of the bottle with its circular groove I-I.

Specification of Letters Patent.

Patented Feb. 29, 1916.

Serial No. 770,008.

For ordinary bottles (Fig. 3), that is to say those that have not been constructed specially and consequently are not provided with a groove, a split ring of square metal wire is employed which is placed on the neck neck. The ring D thus arranged on the neckv of the bottle is for the purpose of offering a sufiicient and regular projection so as to be able to tighten up on it the lower portion of the socket C which could not be done otherwise on account of the irregularity of the bottles which are not specially constructed.

In order to guarantee the contents of the receptacle a sealing band E which is removed by tearing and made of metal or goldbeater skin or other suitable material is placed on the capsule A in a diametral direction. Furthermore its two ends are folded under the lower edge of the socket, so that this sealing band is held by the clamping of the stoppering system on the receptacle (see plan, Fig. 4). This band has two notches F (one on each edge) slightly passing beyond the axis X so as to form a weak point which permits of it being torn when desired.

The system if applied to bottles, ars, pots or the like by one of the means referred to above, it is evident that for unstoppering the receptacle in order to extract a portion of its contents no special instrument will be necessary. It suflices to unscrew the capsule A which carries with it the washer B, this unscrewing movement exerting a traction effort on the band E which is broken at the notches F and which after being completely torn permits of wholly withdrawing the capsule A. In order to restopper the receptacle after use for the purpose of preserving its contents in good condition by excluding the surrounding air, the above operation is. reversed, that is to say the capsule A is screwed back-on the socket C, the washer B again presses on the neck of the receptacle which it hermetically closes. These two op erations are repeated as often as desired, as

long as the receptacle is notempty. By

' means of this system'the contents do not deteriorate or alter and if for example the bottle containsmineral water or beer the liquids retain their gases up to 'the end.

. Thethreading ofthe capsule andthat ofthe socket may be substituted by. any other fastening system such as for example a bayonetjoin.

Having now described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent is:

' An improved stopper for bottles, jars and the like comprising in combination, a

screw threaded capcontaining a washer, a sealing band of metal provided with two notches on each border passing beyond the longitudinal axis of the band, and adapted to be automaticallytorn when the cap is unscrewed for .unstoppering the receptacle,

. substantially as described. a

- In testimony whereof I affix my Witnesses:
