BOTTLE-STOPPER.

Patented May 26,' 1 908.

To all whom it may concern.

Be it'known that I, GEORG KIRKEGAARD,

a citizen of the United States, residing at the city of New York,'in the borough of Brook- 5 lyn and State of New York, have invented certain new and useful Improvements in Bottle- Stoppers, of which the following is a full, clear, and exact description.

This invention relates to Stoppers for that type which comprises a metallic cap with means for engaging an annular shoulder on the exteriorof the neck of the lbottle to hold under compression a'packing disk interposed between the mouth of the bottle and the cap.

The object ofthe invention is tolprovide means for holding the cap .on the bottle against the internal pressure which for its efficiency depends upon the shape or formation of the metallic portion of the cap rather than upon the stiffness or weight of the metal of which the cap. is composed; I am thus able to use a comparatively thin metal for the cap and achieve a corresponding economy in the manufacture thereof.

A further object of the invention is to provide a construction which will aid in the removal of the stopper from the bottle.

My improved construction is illustrated in the accompanying drawing, in which Figure V1 is a side elevation of the cap or stopperfbefore it is applied to the bottle; Fig.

2 is a lan of the same looking at its under side; ig. 3 is asection on line -:v of Fig. 2; Fig. 4 is a section on the line y-y of Fig. 2; Fig. 5 is a section of the cap applied to the bottle and Fig. 6 isa side elevation of the sto per showing a removing device.

he cap com rises essentially a disk 1, hav ing integrally ormed with it a vertical depending wall 2, and a flaring rim 3 dependmg from the vertical wall. The cap contains the usual disk of packing material 4, such. as cork or aper, which is to be com ressed against the mouth of the bottle .to e ect the seal. This cap is adapted to be applied to the common form of bottle having an eXterior annular inwardly inclined shoulder 5, to be engaged b the holding devices on thecap. The said holrding devices of my improved cap are formed upon the flaring rim 3. For this purpose the shape ofthe rim is not flat like a zone from a cone, but is curved like a bottles, jars and similar receptacles,`and is of zone from a dome. It is provided with a series of inwardly and upwardly bent lips 6, each being formed by bending a short length of thel edge of the rim inward and upward, leaving short vintermediate portions of the Vextreme edge unbent, as indlcated at 7, into which the beIit-up lips merge. 'The lips are thus reinforced by their connection with the extreme edge of the rim;

forced downward thereon until the cork is compressed so that the upper edge of the lips will fall within the zone of the shoulder 5. Then by forcing the rim 3 inward to the osition shown in Fig. 5, the upper edges of) the lips will be forced against the shoulder 5 and hold the cap on thel bottle with the cork under compression. The strength of this hold is rest with their edges against the shoulder 5 taper downinto connection with'the eXtreme unfolding or bending downward, and the resistance'of the cross-section of the metal is obtained to prevent the stopper Afrom becoming forced from the bottle.l The machine or tool for applying this cap to the bottle will be very simple, since it will require only the p lunger to press on the top of the cap and a simple ring passed down on the outside of the vertical wall 2 and forced invFvard on the rim 3 to thel position .shown in In Fig. 6 I have shown an improved form of device for facilitating the removal of the cap from the bottle. Various forms of handle have been vheretofore proposed which have been in the form of a strip depending graspedy in the hand to lift one' side of the stopper and thus free it. But where the 'stopper is made of very thin or light metal, as 1s possible in the construction hereinabove described, the simple tail piece is impracticable for handling, since it merely bends and does not afford any leverage to free the cap. Therefore I ypropose vroviding the tail piece 8, which is made a ittle Wider than usual, with an eye or opening 9, in which any tool,

inserted and used to pull the stopper. from the bottle, the thin metal used belng amply strong to stand the force necessary to be eX- erted for this purpose.

from the edge of the cap and intended to bel When the cap is applied toI the bottle, it is i increased from the fact that the lips which edge at 7. Thus the lips are prevented from such as a fork, button hook or a nail, can be 1 05.

Having now described my invention, what I claim, 1s:-

1. A bottle stopper comprising a metallic cap containing a packing disk and having a depending ange provided with a plurality of inwardly and upwardly turned lips merging at their extremities into the eXtreme edge of the flange.

2. A bottle stopper comprising a metallic cap having a packlng disk therein and having a vertical side Wall and a flaring rim or edge projecting therefrom, said rim or edge having a series of inwardly and upwardly turned lips, the ends of which n'lerge into the extreme edge of the flaring rim, for the purpose set forth.

In witness whereof, l subscribe my signa-` ture, in the presence of two witnesses.
