TEA CARTRIDGE.

Application filed August 5, .1920, Serial 130. 401,292. Renewed April 3, 1923.

To all whom it may concern: 1

Be it known that we, BENJAMIN Hlnsorp norm and Louis H nscnnonx, citizens of the United States and Austria, respectively, and residents of the city of New York, county of Bronx, and State of New York, have invented certain new and useful Improvements in Tea Cartridges, of which the following is a. specification.

The present invention relates to a cartridge or ball for percolating or extracting the flavor from tea-leaves or cofiee.

The main object of the'invention is to so construct the cartridge, that, in assembling flexible suspending means secured thereto without the aid of special fastening means. I

Another object of the invention is to provide a wrapper for the cartridge, which is held in position thereon by certain elements of the cartridge proper.

A further object ofthe' invention is to provide a cartridge or the character described which is simple in construction, efiicient in operation, and which is capable of manufacture on a commercial scale, or in other words one which is not so diflicult to produce as to be beyond the reasonable cost of such an article. I

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and constructionof parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in thesize and proportion of the several parts and details of con struetion within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

Two of the many of the invention are illustrated in the accompanying drawings, in which Figure 1 is a. top elevation, partly in section,-of a'eartridge constructed in accordance with the present invention; Fig. 2 is a section taken on line 22 of Fig. 1; Fig. 3 is an enlarged section taken through the jointbetween the elements of the cartridge;

Fig. 4 is a front elevation, partly in section,

of a modified cartridge; and Fig. 5 is a possible embodiments side elevation, partly in section, of the device shown in Fig. 4.

. Referring now first to Figs. 1 to 3, in elusive, of the drawings, the. numeral- 10 ndicates a cartridge in the form of a spher ical shell, consisting of two semi-spherical members 11 and 12, one or both of which may be perforated. These members may be made of any suitable sheet material, for instance metal, such asblock tin. The member 12 is provided with an outwardly NEW YORK, N. Y., ASSIGNORS, i

projecting annular flange 13, onto which is beaded a similar flange 14 upon the member 11. In this manner a ball is formed, into whlclr has been reviously placed a definite quantity of teaeaves orground cofi'ee, as the case may be.

For-the purpose of facilitating the handllng of the cartridge, there isjsecured thereto a flexible means,'sueh as a string 15, to which is attached at its free end a. handle 16, made for instance of cardboard. This string serves also as the means for suspending the cartridge from the receptacle, such as a coffee pot or tea pot, in which the percolation or extraction is to take place. The cord 15 is secured to the cartridge by tying its inner end into a knot 17, and drawing the same through a notch 18 in the flange 14, the notched portion of the flange being then beaded over the flange 13, thereby holding the inner end of-the cord in fixed position upon the cartridge. The sheet material, of which the cartridge is formed, is sufficiently thin to permit ,of the operation described.

In order toobtain a sanitary cartridge, the latter is placed into a Wrapper of paper or similar material. This wrapper may be made of two sections, both semi-spherical, denoted in the drawings by the numerals 19 and 20. The section 19 is held upon the shell member 1.1 by forming in the latter, adjacent the flange 14, an annular groove 21, into which the rim of the wraper section 19 is placed, it being held therein by friction. The wrapper section 20 is kept upon the shell member 12 by the flange 14, when the latter is headed over the rim of the said wrapper against the flange 13 of the v sections. Tongues 24 and 25 are cut into the shell sections 19 and 20, respectively, adjacent the scored lines therein.

lVhen it is intended to brew coffee or tea with the improved device, first the wrapper sections are removed from. the cartridge by taking hold of the tongues 24 and 25 and tearing the said sections around the scored lines 22 and 23. The cartridge is then taken hold of by its handle 16 and lowered into the brewing receptacle, the free end of the string and handle being permitted to hang over the-mouth of the receptacle, after which the-cover of the receptacle is put in place. The cover thus holds the outer end of the cord and handle ready for further operation. Into the receptacle a suitable uantity of boiling water is poured, either be ore or after the insertion of the cartridge; When sufiicient essence is extracted from the rounds or tea-leaves Within the perforated all, the cover is removed from the brewing receptacle and the cartridge withdrawn by grasping the handle l6. v

A modification of the invention is shown in Figs. 4 and 5 of the drawings. differing from the one above described in that a baglike wrapper 26 is used, into which the cartridge is placed. After the cartridge has been'inserted, the mouth of the wrapper is puckered'and the string 15, which extends through the mouth, wound around the wrapper below its mouth, thereby holding the wrapper in position upon the cartridge.

Otherwise the construction and operation of the device are similar to those of the cordance with this invention form convenient packages for the transportation and use of the substances contained therein, and, as such, may be articles of merchandise What we claim is:- r

1. A cartridge for extracting essence from coffee or tea, comprising a. perforated container made of two sections united by means made integral therewith, a string attached to said container, and a. wrapper enclosing said container held thereon by certain elements constituting the cartridge.

2. A cartridge for extracting essence from coffee or tea, comprising a perforated container, a string attached thereto, and a wrapper enclosing said container held thereon by certain elements constituting the cartridge.

3. A cartridgev for extracting essence from coffee or 'tea, comprising a perforated container, a. string attached thereto, and a baglike Wrapper enclosing said container, the mouth of said bag being puckered and said string being wound around the same below its mouth.

.Signed at New York, in the county of New York and State of New York, this 25th day of June. A. D. 1920.
