BoT'rLE-cAP.

which the following is a true and complete specification. r

The object of this invention is to improve upon bottle caps of the kind shown in U. S; Patent No. 1,139,792 dated May 18, 1915, so

that they can be fed and applied to the bottles more efiiciently and without danger of chines largely in use.

WVhile caps made according to said U. S. Patent No. 1,139,792 have been found eflicientand satisfactory, it has sometimes oc curred that because of the fact that these caps have a boss or rise connected to an annular portion, and having an axis substantially perpendicular to the packing disk and hence extending in a vertical line when the cap is on the bottle, that when the caps are fed in an automatic machine, that they wabble or tilt upon this rise or boss, whereby the Y crimped edge of one cap catchesunder anto the bottle, and before the capping operation, i

Fig. 5 shows the structure of Fig. 4 after the capping operation,

Fig. 6 is a top view of the cap as applied on the bottle, the shown, a v

Fig. 7 is a central vertical section of an-' other embodiment of my invention. The cap 1 has the customary crimped side flanges 2, which fit under the edge 3 of the bottle 4 and hold the cap in position in the center thereof. The cap is provided with a boss or rise 5 exactly as in the said U. S. Patent No. 1,139,792. The annular portion of the cap, instead of having substantially crimped edges not being I Speciflcation'of Letters Patent. P t t d J 20, 1920 Application filed April 4, 1916. Serial No. 88,771. I

- straight line elements, or slightly curved-elements as shown in the said former patent,

consists of a raised portion 6 of substantially the same height as the boss 5,.and an intermediate portion 7. Because of this shape when the caps are fed in the machine, in a reversed position, they have a base of substantially the same width as the cap itself and they do not wabble or tilt so as to .catch one upon the other.

As seen from Fig. 5, the rise 6 bein narrower than the walls of the bottle'et, the width of the rise 6 being about 3/64 of an 1I1Cl1 in a cap'of about one. inch diameter, the boss or'rise 6 is drawn in or shaped upon the glass of the bottle in the manner shown in Fig. 5 so that only a slight crease or depression 8 remains which does not mar the appearance of the cap. As the boss or rise is relatively stifi'er and less bendable than the annular portion, the boss substantially retains itsformer shape and relative position, while the annular portion is bent to conform to the shape of the adjacent part of the neck of the bottle,'by the capping operation.

The cap is so designed that as in U. S. Patent No. "1,139,792 when the boss 5 is pushed in, the annular portion 7 is Well driven into the neck of the bottle, and the cork or stretchable lining 9 is stretched and pressedagainst the interior surface of the ,walls of the bottles.

It must be understood that the drawin s are not to scale, as otherwise'the detafis would be too small to be clearly perceptible.

In Fig. 7 I have shown another embodiment of my invention in which the rise 5 of the cap is connected to the crimped side walls 2 by an annular portion 10, which is bent in so that the top of the boss 5 is substantially at the same height as the top of the crimped side walls 2, in this manner the cap is given a broad and secure base and is prevented from wabbling.

I have described two embodiments of my invention, but it is clear that changes might be made in the details thereof, without departing from its spirit as set forth in the following claims.

"The embodiment shown in Fig. 7 assumes the shape shown in' U. S. Patent No. 1,139,792, when it is put on the 'bottle by the ordinary machine, and before the sealing plunger operates.

In the ordinary and well-known bottling machine which is in general use and is so well-known as to require no description thereof, a cap is applied from a chute placed upon a bottle, and the crimped side walls of the cap are secured tothe bottle, by bending the crimps under the bead of the bottle, as is shown in Fig. 5 for example.

The caps made according to U. S. Patent #1139792 have been applied in this manner by the ordinary machine, as is well-known in the art.

The cap having thus been secured to the bottle, the cap is then forced into the bottle by a plunger which exerts a sui'liciently powerful pressure so that the sealing is completed. I

As before mentioned, when a cap made according to this invention is applied to the bottle by this well-known machine, the bending in of the side walls causes the annulus to bend upwardly, so that the top of the boss raised and the cap of Figs. 6 and 7 assume the configuration shown and described in U. S. Patent #1139792.

I claim: a

l. A bottle cap provided with an inner packing disk and having side. walls, a central boss having an axis erpendicular to said packing disk. and an intermediate annular portion connecting the said side walls and. the said boss. the said intermediate annular portion being wider than the walls of th neck of the bottle to which the cap n is to be applied, the top of the said boss being at substantially the same level as the top of the said side 'walls, the said intermediate annular portion having a shape out of conformity with the shape of the said packing disk, the said intermediate annular portion being substantially uniformly bendable. said intermediate annular portion being capable of being uniformly bent so as to raise said boss when the said side walls are fastened to the neck of the bottle, so that the top of the said boss is then raised with respect to the top-of the said side Walls.

2. A bottle cap provided with an inner packing disk and having side walls, a central boss having an axis perpendicular to said packing disk, and an intermediate annular portion of uniform curvature connecting the said side walls and the said boss, the said intermediate annular portion being wider than the walls of the neck of the bottle to which the cap is to be applied, the top of the said boss being at substantially the same level, as the top of the said side walls, the said intermediate annular portion having a shape out of conformity with the shape of the said packing disk, the said intermediate annular portion being substantially uniformly ibendable, said intermediate annular portion being capable of being uniformly bent when the said side Walls are fastened to the neck of the bottle, so that the top of the said boss is then raised with respect to the top of the said side Walls.-

3. A cap having a flat disk and comprising side walls, a central upstanding boss and an intermediate portion, said side walls being crimped and having a top at substantially the same level as the top of the said boss, the said intermediate portion being substantially parallel to the said packing disk, the said intermediate portion and the top of the said side Walls being out of conformity with the shape of the top of the bottle.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing Witnesses.
