Filed Dec. 21; 1940 INVENTOR: 4 HERMA BY KML mWw Patented July 28, 1942 INFUSION CONTAINER Hermann Schiess, Basel, Switzerland Application December 21, 1940, Serial No. 371,090 In Switzerland January 27, 1940 8 Claims.

The article, object of the present invention, is an infusion container for tea and other beverages, particularly suitable for the catering trade, with a lid and a container shaped in low cylindrical form which are put together on one side, and on the other side have a bottom, each of these bottoms protruding inwards and forming a collar destined for the reception of the holder, whereby both parts, i. e. the lid and the container, are held together in this collar by means of a rivet.

With an infusion container constructed as set forth above, the fastening point of the lid and the container is thus hidden and is inaccessible so that the rivet forming the connection between these parts cannot be broken, not even with a special tool, without, at the same time, breaking the other parts surrounding the collar. Moreover, the special form of the container ofiers the great advantage that one and the same stamping tool with the corresponding die, suffices for the manufacture of both the lid and the container.

An example of an execution of the article according to the invention is illustrated in the drawing in which:

Fig. l is a cross sectional view of the container according to the invention and shows a part of the holder in a position ready for insertion into the container,

Fig. 2 is an illustration of the container viewed from above in the direction of arrow II in Fig. 1,

Fig. 3 is a side-view of the container with a holder inserted therein, and

Fig. 4 illustrates the container with a flexible holder.

Like parts are designated by like numerals in all figures.

Figs. 1-3 illustrate the container I having perforations 2 in the form of radially-placed narrow slits and permitting access of water to the infusion matter and the lid 4. Part I and part 4 is each provided with a hollow stem or collar portion 5, each of said portions having a slightly conical bore into which a solid holder in the form of a handle with a piston-shaped cylindrical end may be inserted temporarily. The container l and the lid 4 may be made of light metal or a Bakelite material which, even when subjected to certain changes of temperature as, for instance, when dipped into hot water, remain completely odorless andtasteless. The lid 4 and the container l are of exactly the same shape and appear as low cylinders 4a which, on one side only have a bottom la in the form of a flat cone. The outer rims l6 and 4b of parts I and 4 are of increased thickness and abut one another and form a circular-shaped joint l5. The ends of the inwardly projecting collar or hollow stem parts 5 are each provided with an inwardly projecting collar I0 and 40 respectively separating the inner part of the container and do not reach quite as far inward as the joint l5, so that a small space remains between the two collars I0 and 40, as can be seen in Fig. 1. This is intended to prevent any cracking of the container when riveting the lid and container together. A rivet I6 is inserted in the small opening of collars lo and 40 which rivet holds the two parts I and 4 firmly together so that they cannot be separated one from the other, without breaking the rivet and surrounding parts.

This rivet I6 is hollow and its outside diameter is somewhat smaller. than the diameter of the bore in the collars lo and 4c. The ends of the hollow rivet are bent outwards at about as illustrated in Fig. 1. The outside diameter so applied to these bends touches the inner surface of the hollow portions 5, thereby centering both the container l and the lid 4. The rims lb, 41) of the container I, as well as of the lid have an outwardly protruding reinforced edge where the rims meet, which prevents any jamming of the containers if these are, as intended, packed one on top of the other in tubular storing containers.

The construction of the container in the manner described offers the two following advantages: (a) that for the manufacture of the two parts I and 4 only one stamping tool or casting mould is required according to the process used, and (b) that the holder can be fastened either in the lid or in the container.

The infusion container as per Fig. 4 is substantially the same as that shown in Figs. 1-3, the only difference being another kind of holder, such holder consisting of a flexible material as, for instance, cotton thread, wire, a small chain or a similar article, which is fastened to a removable stopper IB inserted in the hollow stem portion of the lid 4.

The size of the containers is ample to allow the infusion material or matter contained therein to expand. The long, narrow slits ofier the advantage of properly withholding the infusion matter in spite of the ample section for the water circulation, which is not the case with the usual system of small round perforations.

Having now particularly described and ascertained the nature of my invention, and in what manner the same is to be performed, I declare that what I claim is:

1. An infusion container for tea and other beverages, including perforated half-shell members, each of said members having an outer rim, said rims abutting one another when the container is closed, each of said members being provided with an inwardly protruding hollow stem portion, said stem portions having end portions facing one another when the container is closed, and sealing means interconnecting said end portions and permanently holding said shell members together and holding said container in assembled and closed condition.

2. An infusion container for tea and other beverages, including perforated half-shell members, each of said members having an outer rim, said rims abutting one another when the container is closed, each of said members being provided with an inwardly protruding hollow stem portion, said stem portions having end portions facing one another when the container is closed, and rivet means, interconnecting said end portions and permanently holding said shell members together and holding said container in assembled and closed condition.

3. An infusion container for tea and other beverages, including perforated half-shell members, each of said members having an outer rim, said rims abutting, one another when the container is closed, each of said members being provided with an inwardly protruding hollow stem portion, said stem portions having end portions facing one another when the container is closed, and hollow rivet means interconnecting said end portions and permanently holding said shell members together and holding said container in assembled and closed condition.

4. An infusion container for tea and other beverages, including perforated half-shell members, each of said members having an outer rim portion, of increased thickness, said r-im portions abutting one another when the container is closed, each of said members being provided with an inwardl protruding hollow stem portion, said stem portions having end portions facing one another when the container is closed, and sealing means interconnecting said end portions and permanently holding said shell members together and holding said container in assembled and closed condition.

5. An infusion container for tea and other beverages, including perforated half-shell members, each of said members having an outer rim, said rims abutting one another when the container is closed, each of said members being provided with an inwardly protruding hollow stem portion, said stem portions having end portions comprising inwardly protruding collar means and facing one another when the container is closed. and a hollow rivet extending through said collar means and having ends bordered over said collar means and interconnecting said end portions and permanently holding said shell members together and holding said container in assembled and closed condition.

6. An infusion container for tea and other beverages, including perforated half-shell members, each of said members having an outer rim, said rims abutting one another when the container is closed, each of said members being provided with an inwardly protruding hollow stem portions, said stem portions having end portions comprising, inwardly protruding collar means and facing one another when the container is closed, and a hollow rivet extending through said collar means and having ends bordered over said collar means and abutting the interior walls of said hollow stem portions and interconnecting said end portions and permanently holding said shell members together and holding said container in assembled and closed condition.
