2 Claims.

This invention relates to a novel and improved form of means for tightly closing a container, the novel features of which will be best understood from the following description and the annexed drawing, in which I have shown selected embodiments of the invention and in which:

Fig. 1 is a view showing a container with the cover thereof removed and one form of sealing member applied thereto, this view being taken on the line 1-1 of Fig. 2;

Fig. 2 is a view taken on the line 22 of Fig. 1;

Fig. 3 is a view on an enlarged scale but on the same plane as Fig. 1 and showing the cover and other parts in place on the container;

Fig. 4 is a view on the same plane as Figs. 1 and 3 but showing a slightly different form of sealing member;

Fig. 5 is a view similar to Fig. 4 but on a smaller scale and showing still another form of sealing member. v

The invention is shown as applied to a container in the form of a jar 1, although other forms of containers may be used. The container has an opening, here formed by the upward continuation of the cylindrical wall of the jar, this wall terminating in an edge 2 which is continuous and preferably circular in form and lying entirely in a single plane. The jar may have, adjacent the edge 2, one or more threads 3 on its outer surface adapted to engage internal threads 4 on a downwardly extending flange 5 of a cover 6, so that this cover may be secured in place on the container end, when so secured, will extend over the edge 2. In this connection, I shall, for the sake of convenience, refer to the structure as though the jar or other container were resting upon a horizontal surface and extending vertically above such surface, although it is to be 'understood that this is merely for convenience in defining the relative positions of the parts.

In Figs. 1, 2, and3, I. have shown a sealing member '7 in the form of a disk of sheet material having a fiat peripheral edge portion 8 resting upon the edge 2 of the container. Disposed inwardly of this edge portion, the disk is provided with a V-shaped depending bead 9 with straight sides, one of them having a surface 10 engaging the wall at the inside of the edge 2. It will be seen that this surface 10 extends inwardly and is inclined inwardly and downwardly away from the inner surface 11 of the wall of the container and that the upper edge 12 of this surface is of greater diameter than the inner surface 11 of the container wall, so that when the disk is placed in position on the container before the cover is applied, the edge portion 8 will be out of contact with the edge 2, as plainly shown in Fig. 1.

The cover 6 has a horizontally extending shoulder 13 disposed directly above the edge 2 when the cover is fastened to the container, and one or more suitable packing disks or gaskets 14 may beput in position within the cover and engaging the shoulder 13, this shoulder preferably being a continuous peripheral one.

In operation, the disk '7 is put in place as indi- 10 cated in Fig. 1, the inclined surface 10 aiding in centering the disk, and then the cover 6 is screwed downwardly into the position shown in Fig. 3, where it will be seen that the edge portion 8 of the disk 7 is forced towards the center of the con- 15' tainer and downwardly against the top edge 8 of the container wall. The action is a wedging one, serving to form a tight seal between the surface 10 and the wall of the container. This sealing action may be increased by forming the 20 disk '7 of resilient material, such, for example, as celluloid or other cellulose composition, so that there is a tendency for the disk '7 to buckle upwardly as the cover is screwed down. This tendency maybe counteracted by having the central 5 portion 15 of the disk '7 at such an elevation that it will contact with one of the disks 14 when the cover is screwed down tightly, as in Fig. 3. Because the buckling is resisted, it will be seen that the surface 10 is thus forced more tightly into 30 engagement with the wall of the container.

Referring now to Fig. 4, I have shown therein a slightly different embodiment of the invention. In this form, the disk '7 has a bead 9' formed with curved sides and a rounded bottom 16 and 5 its edge portion 8 is likewise rounded or concaved downwardly in place of being fiat as in Figs. 1, 2, and 3. In other respects, this form follows closely that previously described.

In Fig. 5 is shown a slightly different embodiment in which the disk "I" has a central portion 15 depressed so as to be below the edge 2 of the container wall and so that it joins the lower edge of the inclined surface 10'. Otherwise, this form will also function in the same manner as described above.

While I have shown the invention as embodied in certain specific forms, it is to be understood that various changes in details may be made without departing from the scope of the invention, and I therefore do not intend to limit myself except by the appended claims.

I claim:

1. In combination, a container having an opening therein bounded by a cylindrical wall having portion of the disk-against an edge,a disk extending across 'ing said wall within said edge said opening and having an edge portion thereof engaging said edge of the container, a surface on said disk disposed inwardly of said edge portion thereof and engagand extending downwardly within the opening and inclined away from the wall, the maximum diameter of said inclined surface being greater than the diameter of said opening, a cover for said opening of greater diameter than the opening and extending across said edge, and means to secure the cover to the container and in so doing to force said inclined surface into said opening and said edge said edge or the wall, said disk being made of resilient material, whereby said inclined surface is resiliently forced into engagement with the edge portion of the wall by securing the cover to the container.

2. In combination, a container having an opening therein bounded by a cylindrical wall having an edge, a disk extending across said opening and surface having an edge portion thereof engaging said edge of the container, a surface on said disk disposed inwardly of said edge portion thereof and engaging said wall within said edge and extending downwardly within the opening and inclined away from the .wall, the maximum diameter of said in- 'clined surface being greater than the diameter of said opening, a cover for said opening of greater diameter thanthe opening and extending across said edge, means to secure the cover to the con-- tainer and in so doing to force said inclined into said opening and said edge portion of the disk against said edge of the wall, said disk being made of resilient material, whereby said inclined surface is resiliently forced into engagement with the edge portion of the wall by securing the cover to the container, and a second disk disposed within the cover and engaging the first-named disk to prevent its buckling upwardly.
