Specification of Beissued Letters Patent. Reissued Jan, 3, 1922,
Original No. 1,335,054, dated latch 80, 1920, Serial No. 245,800, filed July 17, 1918. Application for reissue filed February 28, 1921.
To all whom it may concern:
Be it known that I, CHARLES HAMMER, a citizen ofthe United States, and resident of Queens, county of Queens, State of New York, have invented certain new'and useful Improvements in Friction Closures for Containers, of which the following is a specification.
This invention relates to caps or closures that are applied to containers, such as jars or bottles, particularly those containers which have a straight outer sealing wall, and do not depend upon screw threads or grooves to hold the cap on the container.
The object of the present invention is to provide an improved .form of closure .of this character adapted to be loosely placed on the container and secured thereon by a mere application of downward pressure on topof the container, especially at the outer portion thereof; and whlch container will provide a secure sealing surface for engagement with the outer wall of the container; and which closure will receive a sealing gasket and retain it inside of the closure until applied to the container, and which will further form a kind of wedge shape to the gasket that converges downwardly, on application of the closure.
In the accompanying drawing showing embodiments of my invention, Fig. l is a vertical section through a portion of a container and closure, as the cap is first applied to the jar.
Fi 2 is a similar view showing the closure orced down on the container.
Fig. 3 is a view similar to Fig. 1 showing the sealing gasket or ring.
Fig. 4 shows the latter forced down on the container.
Fig. 5 is a partial plan view of the closure.
The closure is shown as comprising a top member 5, having a flange 6 extending downwardly therefrom, which flange is conically inclined downwardly and inwardly. The flange portion 6 connects with the top 5 by a flat portion 4 at the outer part of the top, that extends in a horizontal plane, as shown. The conical portion 6, at its connection with the flat top may be given a. small curve, as shown in the several views.
The lower portion of the flange extends downwardly and outwardly, as indicatedat 7; and if desired, the raw edge may be bent Serial No. 448,591.
to'form a closed head 8. This flaring end portion adapts the closure, when placed on top of the container or jar 1, to engage the outer portion of its rounded upper edge 3. The jar is shown as provided with a substantially straight or cylindrical outer wall 2.
The lower flaring portion 7 is shown as connected with the upper conical inwardly inclined portion 6, by a portion 9 that extends inwardly from the lower part of the conical portion 6, whereby is formed on the inner wall of the flange a shoulder indicated by 12. As shown this connecting portion 9 is curved between the conical portion 6 and the flaring portion 7, which curve is convex on the inner wall of the flange. This annular convex portion constitutes the engaging part ket 10, of suitable composition that will admit of compression, to conform to the shape of the chamber constituted by the flange and top of the closure, and the outer and upper wall of the container, see Fig. 2. This gasket is inserted in the container, and is preferably shaped as shown with the lateral thickness'less than the height, and is adapted to engage the top straight wall 4 of the container, and rest. on the ledge 12, as shown in Fig. 3; which will serve to securely retain the gasket in the closure before application to the jar.
In the use of this closure, it is placed loosely on top of the jar as indicated in Fig. 3, with the gasket inserted; or as in Fig. 1, with the gasket omitted. Pressure is thereupon exerted downwardly on top of the cap, at the outer flat portion 4, by any suitable device, and the closure will be forced down on the jar. The convex portion 9 engaging the top rounded edge of the jar at its outer part, will be forced slightly outward, and will then pass down the cylindrical wall 2 of the jar, as shown in Fig. 4. As the closure gasket will engage the upper edge of the ar, that will force the gasket outward and cause it to be received in the wedge-shaped chamber between the conical flange portionv 6 and the jar wall. The horizontal width of the gasket is preferably slightly more than this wedge-shaped chamber at its lower portion, to insure the compression of the gasket; and this will causethe upper portion of the gasket to expand slightly and fill, the space between the top and conical wall of the closure, and the outer and top wall of the container, as clearly shown in Fig. 4.. The slight expansion of the closure at the part- 9, will follow any irregularities in the jar wall and size, and it will securely grip the jar; at the same time the flexible gasket will completely fill the chamber between the jar wall and the closure, and form a hermetic seal.
