CLOSURE FOB, CONTAINERS.

Specification of Letters Patent.

Application filed April 28, 1916. Serial No. 94,223.

To all whom it may concern:

Be it known that TRUMAN T. LAYNG, a subject of the King of Great Britain, residing at Band, in the Province of Alberta and Dominion of Canada, have invented certain new and useful Improvements in Closures for Containers, of which the following is a specification.

This invention relates to closures for bottles, jars and the like and has for its object to provide a self-sealing closure, designed to be made in all sizes and which, when applied, forms an air tight seal on all vessels having an outwardly projecting bead or the like at the mouth thereof.

W'ith this as the principal object in view and other minor objects to be set forth in the accompanying description, the invention consists of the novel construction and combination of parts herein disclosed and illusdrawings, in.

trated in the accompanying which- Figure 1 is a vertical sectional view of the mouth of a vessel provided with the improved closure in its sealed position;

Fig. 2 is a similar view of the sameparts showing the closure in place on the bottle but not sealed; and

Fig. 3 is a plan closure.

Fig. 1 is a detail sectional view showing a modified form of closure.

Referring to the drawings by numerals, 10 indicates the neck of a bottle, jar or other container having an exterior head 11 at the mouth thereof. The form of this bead may vary widely, it being only necessary that it project short distance beyond the exterior surface of the jar at or near the mouth thereof.

12 indicates a reversible closure which comprises two disks 13 and 14 of the same shape and diameter, and a skirt 15 secured between the two disks which, when in operative position, overhangs either disk 13 or disk 14 according to which is engaged with the bottle mouth, and the bead 11 on the container 10, disk 13 being herein shown so engaged.

These disks are preferably made of a relatively hard but more or less yielding rubher, but if desired, may be made of paper board rendered water proof by parafiin wax, or of other suitablepliable material.

The disks 13 and 14 secure between them, the inner edge 16 of the skirt 15 which operview of the seal and of the container below the same.

. contact of the disk ates to space the disks apart at that portion which is disposed over the opening in the bottle mouth, a distance sufficient to permit the inner or bottle engaging disk to yield when pressure from the inside is brought to bear against it, such as might be caused by olives, peaches or the like, or should the contents expand for any other reason, for instance, by freezing. The outer portion of the skirt extends in the form of a cup over the bead 11 as previously explained. The skirt 15 is made of a soft, rubber, the cylindrical portion 17 of which terminates at the open end in a bead 18 that gives strength to the edge of the skirt and bein made of slightly less diameter than the isks, closely hugs the container 10 be low the bead and fits snugly against the outer bulging portion thereof. This skirt 15 is formed with an opening that is almost the same diameter as the disks 13 and 14 which provides a space between these disks. From this it will be seen that should the receptacle be filled with whole fruit, such as peaches or the like, there will be no strain on the skirt 15 owing to the pli-ability of the disks the inner of which is free to move until it engages the outer.

U11 the outer face of the disk 13 there is shown an annular extension 19 designed to enter the mouth of the container when the closure is in the position. shown in Fig. 1. With fruit ars and the like the annulus 19 may be made with a diameter exterior-1y equal to the disk 13 so that said annulus may fit over the mouth of the jar instead of within the mouth of the container, as shown in Fi 4.

Before placing the closure upon a container the skirt 15 is rolled upwardly about the bead l8 and presents the appearance shown in Figs. 2 and 3 when the disk 13 is to be placed in contact with the container. 1n this condition it may be placed over the mouth of a container 10 and by a quick movement the skirt unrolled until it extends downwardly over the bead 11 and below the same closely hugging said head and the wall An airtight joint is thus produced which i supplemented and rendered more secure by the 13 and annulus projection 19- held against the mouth of the container by the natural contraction of the soft rubber forming the skirt 15. l fhile the closure is shown with disk 13 engaged with bottle 10,

quite flexible it is to be understood that it may be reversed and disk 14 engaged with the container, and when in this position, disk 13 will operate as a stop and support for the skirt when rolled into inoperative position.

If desired the skirt 15 and disks 13 and 14 may be made integral or when formed of rubber vulcanized into one inseparable article instead, as shown in the drawing for illustrated purposes, beingmade of three separate members united by some cement or other means of connecting them together.

While I have shown in the drawings and described above what I consider to be the preferred form of the invention, it is to be understood that various changes may be made in the construction and arrangement of parts without departing from the spirit of this invention.

I claim:

A closure of the class described comprisin a reversible air-tight cap formed of two pliable disks of the same diameter arranged in superposed relation whereby their peripheral edges are disposed flush with each other when assembled, said disks being constructed of non-corrodible, non-checkable material, and one having an annular extension on its outer face to fit the mouth of thecontainer, a skirt of flexible rubber, with one edge secured between said disks and spacing the disks slightly apart at their centers to provide for yielding .of the container-engaging disk relatively to the other, said skirt converging toward its free end and provided with a bead at the edge of said end said skirt when in .operative position pro ecting below the lower disk and adapted to be rolled upwardly with the roll engaging the periphery of the upper disk which operates as a support for said roll to prevent tearing strains and undue stretching of the skirt when not in use, thereby prolonging the life of the closure.

In testimony whereof I aflix my signature in presence of two witnesses.
