oLosURE FoR CONTAINERS.

Application l'filed Jiune 12,

To all 'whom t may concer/t:

Be it known that I, DAVID BLooM, a citizen of the United States, anda resident of Berkeley, county of Alameda,"and Staterof California, rhave invented a new and useful Closure for Containers, of which the followin is a specification.

iy inventionrelates in general to closures for containers and has articular reference to an improved means or effec-ting a posi- While the invention is applicable to an unlimited different type of containers, fo-r the purpose of illustrating the salient features of the idea the closures will be herein described and illustrated as applied to jelly and the like tumblers or glasses.

The primary object of the invention is to provide a closure which will effect a positive seal and which may be produced in quantity lots at a modest cost so that the commercial possibilities of the invention may be realized to the fullest extent. Another feature of the invention resides in the simple manner in which it is applied, which will enable the closure to be used by housewives aS well as packers operating on a large scale.

The invention possesses further features which will appear as the description now proceeds with reference to the accompanying drawing, in which Figure l is a view in side elevation and Vartly in section of a socalled jelly glass illustrating the application on the preferred embodiment'of the iiivention; Figure 2 is a top plan view of the cap; I'Figure 3 is a horizontal section. through the cap; Figure 4 is a detail view illustrating the application of a supplementary protecting cap and Figure 5 is a view in vertical section of a slightly modified form of container illustrating the application of the invention.y

Referring now to the drawing in detail, (5) represents the container whichhas previously stated, for the purpose of illustration I have elected to show as an ordinary jelly glass or tumbler. It is highly desirable to seal the container with paraffin in order to effect a positive air tight closure, not onlyto protect the contents of the container but also to exclude air to prevent fermentation of the contents or other de teriorating results.

According to my idea I propose to use a 1922. Serial No. 567,669.

cap (6) for the open top of the container, the cap being produced preferably from parchment paper,but other material may prove just as effective, for instance, a cloth gauzemay be employed. In any event the cap is made by stamping or` otherwise form- -ing the material to leave an insert (7) with an outwardly'projecting flange (8) at the upper edge thereof. The insert part of the cap is made of Substantially the same diameter as that of the open end of the container and is adapted to be inserted therein with the fiange (8) turned Adownwardly over the outer edge of the container as best shown in Figure l, and to anchor or fix the cap in the container Iproposeto coat or otherwise' apply an adhesive substance to the under side of the flange (8) so as to stick the downwardly turned flange to' theside of the container. The adhesive substance may be applied at the time the caps are made up, or individually at the time the cap is to be used. vThis is, of course, immaterial so far 'as concerns the spirit of the invention.

Itis of course, known that paraffin is an appropriate sealing agent and I therefore propose to take advantage of the quality of the same in combination with the cap. To realize this effect I perforate the insert part of the cap as at (10) by making small openings at spaced intervals around the sides of the insert part and also as at (ll) by making small openings in the bottom of the in- Sert. If desirable a large opening (12) may be used in the bottom. When the cap has been adjusted in place on the container and, of course, after the container has been filled, and it might be well to mention here that the container should not be filled to the top but a space should be left between the container and the bottom of the insert, the melted paraliin is poured into the hollow of the insert part of the cap and the same runs through the perforations and occupies the space between the contents (A) and the bottom of the insert and also between the Sides of the insert and the inside of the container. Suiicient paraffin is used to imbed the insert part of the cap, as shown to best advantage in Figure I. It is desirable that the paraiiin occupy the whole of the space beneath the bottom of the insert and the contents of the container as well as the sides of the container and the sides of the insert. Where the word paraffin is used, it

should,lbe considered as qualifying any like substancel that would be appropriate,

As a supplementary covering or protecting cap I can use a device, vasv best shownat (13) in Figure 4, which Willslip overthe cap (6) and rotect the same.

For some ood stuffs, it makes no differ- `ence Whether the parafiin contacts directly `or the like (15) so as to 'separate the paraffin from the contents; Aside from the introduction of this disc between the contents and the paraffin, the invention embodies the same characteristic features.

I claim: y

1. A closure of the` class "described, embodying a perforated insert for the .open end of a container, said insert adapted to provide a receptacle foru a paraffinV likesealing agent withl the perforationspermitting the insertfto .beembedded in said sealing agent. y f2.
