Specification of Letters Patent.

Patented July 13, 19261 Application filed October 12, 1917. Serial No. 198,169.

- and residents of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Closures for Jars, Bottles, and other Receptacles, of which the following is a speci fication. The invention resides more particularly in a cap of tin or other suitable metal, with a special compressible gasket in the flange or skirt portion thereof, adapted to the effectual sealing of glass tumblers, jars and other containers or receptacles having smooth exterior surfaces of substantially rigid or unyielding character.

One purpose of the invention is to provlde a cap and gasket readily capable of being eflectually sealed against the exterior surfaces of a glass tumbler or like container by pressure applied downwardly and annularly' against a beaded portion of the skirt of the v cap holding the gasket to be compressed against the exterior surface or wall of the container. 1 r 7 Glass tumblers and like containers are diflicult to properly seal owing to defects in the upper edge portions thereof due to the conditions under which such containers are manufactured, and as an illustration we may mention that the upper exterior surfaces of the container, while intended to be straight, are frequently tapered, and also that while the upper portions of such containers are supposed to be true they frequently have irregularities in their surfaces and in many instances have what are called crizzles, which are very fine grooves or the like sometimes almost imperceptible to the eye or touch, but uite suflicient to prevent, under many con itions, the hermetic sealing of the container by many of the closures at the present proposed. One of the principal purposes of our invention is to provlde a closure which may be utilized in the efiectual sealing of a contalner, regardless of the usual irregularities in the exterior surfaces of the upper end portion thereof and regardless of such irregularities and crizzles as may be present along the upper edges of the container.

In carrying out our invention we provlde a metal cap adapted to pass downwardly over the upper end of the container and having a depending encompassing flange or skirt portlon which is shaped or grooved torecelve the gasket or packing ring, said flange or skirt portion having a plain upper peripheral section and the groove or beading 1n said flange being located below said plain section and projecting on annular lines outwardly from the vertical plane thereof and adapted to receive the gasket or packing ring. The cap and gasket or packing ring are of such dimensions with relation to the upper outer portions of the container that they closely fit upon the same when applled thereto, and thereafter the scaling is eflected by a downward pressure against the upper outer portions of the beaded section of the flange, whereby said section and the gasket or packing ring contained therein are pressed downwardly and inwardly toward the outer walls of the container, with the result that the said gasket or packing ring becomes greatly compressed against the walls of the container and is held in such condition and position by'the beaded section of said flange, said gasket or packing ring then providing an effectual seal of adequate area regardless of the usual irregularities that may be present in the container. The compression of the beaded section of the flange or skirt portion of the cap and the gasket or packing ring held thereby also results in the lower edges of the packing ring being squeezed downwardly below said section of the cap, and this is imv portant since by reason thereof a person desiring to open the receptacle may, with a fork or other instrument, draw the packing ring downwardly from the cap, thus breakgasket being illustrated in their initial con dition or before the sealing step of the process has taken place;

Fig. 2 is a like view of the same showing the relation of the cap, gasket and tumbler, after the beaded sect on of the flange or skirt portion .of the cap has been driven downwardly and inwardly, to compress the gasket against the container;

Fig. 3 is a vertical section of a fra 'mentary portion of the container, cap and gas ket in their initial relation, together with a sectional portion of a cylindrical tool by which the beaded section of the flange or skirt portion of the cap and the gasket or packing ring held thereby, may be pressed inwardly and downwardly toward the container or to the condition shown in Fig. 2;

F ig. 4 is a like View of the same showing the relation of the parts when the applying tool has been driven downwardly to compress the gasket against the container;

Fig. 5 is a sectional fragmentary view corresponding with Fig. 3, but illustrating a modified form of the beaded section of the flange or. skirt portion of the cap, and

Fig. 6 is a like view of the same showing the relation of the parts after the applying tool has been driven downwardly against the beaded section of the flange or skirt portion of the cap to compress the gasket held thereby against the exterior surfaces of the container.

In the drawings,referring to Figs. 1 to 1 inclusive, 10 designates a container, which may be a glass tumbler, 11 the cap,'12 a downwardly depending flange or skirt constituting a portion of said cap and in its upper part adapted to closely fit upon the upper exterior portion of the container, 13 an annular beading formed in the lower portion of said flange or skirt, and 14; the gasket disposed within the groove formed in said beading andadapted toengage the exterior wall of the container 10.

The container 10 has plain exterior walls, and the cap 11 is adapted to close the upper end ofthe container and at the upper portion of its flange or skirt 12 to snugly encompass the upper outer walls of the container. The beading or grooved portion 13 of the capmay be of varied formation, but the preferred construction thereof is illustrated in Figs. 1 to 4 inclusive, in which it may be seen that the upper portion of the beading 13 has a wall 15 which diverges downwardly and outwardly in a direction from the container and that from the lower outer edges of said wall 15 a vertical wall or flange 16 extends downwardly and sets outwardly from the side wall of the container. The normal condition of the walls 15, 16 constituting the beading 13 is shown in Figs. 1 and 3, and within said beadingis located the compressible vertically elongated gasket or packing ring 14 having anupper downwardly and outwardly inclined surface corresponding with the wall 15 of the bead-.

the beading 13 may be turned inwardly to I a slight extent, as shown in Figs. 1 and 3,

' so as to facilitate the assembling of the cap its lower inner edges inclined downwardly and gasket and the application of the same in assembled condition upon the container.

In accordance with our invention we de-- press the beading 13 and gasket 14 downwardly and inwardly tpward the container and at the same time materially elongate the same, the gasket being elongated by its compression inwardly to a materially reduced thickness, and the heading being elongated by having its walls depressed downwardly and moved inwardly toward the container. The gasket and heading are by the method of applying the closure-to sealing position, transformed from the condition in which they are represented in Fig. '3 to that illustrated in Fig. 4. The compression of the gasket 14: results in the lower edges thereof being protruded below the lower edge of the heading 13, and this has the beneficial effect of so exposing a portion of the gasket that by means of a fork or other convenient means the gasket may be extracted downwardly from the heading when it is desired to remove the cap from the container. The

beading 13 is open at its lower end and thus no difliculty is experiencedduring the compression of the beading and gasket in causing a portion of the lower edges of the gasket to become exposed below the beading.

The preferred method of compressing the beading 13 and gasket 17 downwardly and inwardly toward the container is indicated in Figs. 3 and 4 and comprises the employment of a cylindrical tool or die 17 having and outwardly, as at 18, and its surface above said inclined portion 18 vertical, as at 19. The die 17 is cylindrical and hollow and of the requisite predetermined inner diameter to eflect, when moved downwardly on the cap, the compression of the beading 13 and gasket 14 downwardly and inwardly or transform the same from their condition represented in Fig. 3 to that illustrated in Fig. 4.

We deem it ofimportance that the beading 13 is below an upper plain section or .portion 20 of the flange 12 and that the lower edges of said beaded portion 13 are open and away from the container so that the gasket may be caused to protrude downwardly below the said beaded portion when the cap is in final position on the container. The walls of the container are unyielding, and hence with a cap and gasket of the character shown and described we are enabled to secure a very effectual sealing of the container and one which is efficient notwithstanding. any irregularities, crizzles or the like that may be present around the upper edges of the container. The closure of our invention is entirely eflicient whether the walls of the container are straight or beveled.

that the downwardand inward pressure of the heading 13 and gasket 14 will make an eflicient seal regardless of whether the upper exterior walls of the container are vertical or tapered.

In Figs. 5 and 6 we illustrate a modified form of the closure, and therefore in these figures number the cap 22, its flange or skirt portion 23 and its beading 24. Within the heading 24 is formed an angular groove holding a gasket or packing ring 25 which is of ob ong shape in cross-section, be-

ing thicker vertically than in width. The

lower end of the heading 24 is open so that finally the gasket may have a portion of its lower edges squeezed downwardly therefrom, and the metal at the lower outer edge of the beading 24 may be flanged inwardly to a slight extent to facilitate the assembling of the cap and gasket andthe application of the same in their assembled condition upon the container 10. The normal condition and relation of the heading 24 and gasket 25 are illustrated in Fig. 5, while in Fig. 6,

the said beading and gasket are shown in the relation they occupy after they have been acted on by the tool or die 17 to compress the beading and gasket downwardly and inwardly toward the exterior wall of the container, the said heading and gasket being,

during and b this operation, vertically elongated and tii squeezed from the lower edges of the beading, so that said edges of the gasket become exposed, as in the constructlon shown in Fig. 4. When the beading 24 and asket 25 are moved downwardly and inwar ly toward the container by means of the die 17 said heading and gasket take substantially the outline illustrated in 4, as will be understood on reference to I ig. 6.

Our invention comprises the cap having the lower heading in its flange or skirt and a gasket within said beading, said beading being open at its lower end and said beadthe invention to details otherwise than the appended claims may require.

What we claim as our inventionand desire to secure by Letters Patent, is:

1. In combination with a receptacle having plain exterior surfaces, a side seal closure of the character described therefor comprising a cap adapted to seat on the top of the receptacle and having a depending flange or skirt portion adapted to encom-.
