TEA CARTRIDGE Filed Oct. 4, 1929 INVENTOR Patented. Se t. 9,-1930' v UNITED STATES PATENT OFFICE IBENTAIIN' 'HIBSCHHOBN, OIPNEW YORK, N. Y., ASSIGNOR '10 MILLIE PATENT HOLD-- IN'G CO., INC., 01' NEW YORK, N. Y., A CORPORATION OF NEW YORK I TEA oan'rnrnon Application fledflctobcr 4, 1929. Serial No. 397,885.-

The present invention relates to improvements in tea-cartridges of the type shown in Letters Patent #1,493,981, granted to me on May 13, 1924. In the Letters Patent mentioned, a device for extracting essence from tea-leaves or coffee is described, com rising a tube of textile fabric having both ends drawn into folds, -a metal strip encircling and compressing the folds'on each end ofthe 1o tube for closing said ends, and a suspending string held in place by both metal strips. These devices, While comparatively easy to manufacture, have been found objectionable by the trade because of their form, the trade being generally used to tea-cartridges the v container of which is in the form of an ordinary bag.

The main object of the present invention 1s in my above mentioned Letters Patent which,

however, is so shaped that it assumes the form of an ordinary bag. I One embodiment of the invention is illustrated in the accompanying drawings, in which v Figure 1 is a central vertical section taken through a tea-cartridge constructed in accordance with the present invention; Fig. 2 is an elevation of a tube of which the container of the said cartridge is formed; Fi 3 is a similar elevation'of the said tube wit one ofits ends gathered into folds and with the suspending string attached thereto; and ig. 4 is a section taken through the device shown in Fig. 3, the tube being inverted.

In the drawings the numeral 10 indicates a tube of open-mesh textile fabric, such as cotton, it being made, for instance, of a single piece of fabrlc, folded to form two plies, which are joined by a row of stitches 12. In producing the cartridge, one end of the tube is gathered into folds to form a neck 13 (Fig. 3) andone end of a suspending string 14 tied around the said neck, whereby a container 15 is formed. This container is then inverted, as shown in Fig. 4; of the drawings, the suspending string being extended centrally therethrough. Tea-leaves or coflee for a n day of October,

singlebrewing are then glaced into the inverted container shown in ig. of the drawto provide a bag of the character described ings, after which the mouth of the container is gathered by puckering the same and applying thereto a metal strip 16, which is shaped to assume the form of a ring so as to prevent escaping of the contents of the ba To the free end ofthe suspending string 1s attached in any suitable manner ahandle 17 of pasteboard or like material. The sus-' pending stringextends through the ring 16, it being clamped by the latter to the puckered mouth portion thereof. Inasmuch as that portion of the string which is disposed within the container is shorter than the height of the latter, it is obvious that the neck 14 on the bottom portion of the container is held within and-concealed by the container, so

nary bag.

In some instances it may be desirable to extend the suspendin string slidably through the ring 16, su cient friction being however maintained between the mouth portion of the .bag and the said string to ordinarily maintaln the container in the bag shape. The purpose of this arrangement is to permit the bag to be collapsed in the brewin receptacle after-the brewing operation.-

A device for extracting essence from tea-leaves or coffee, comprising a tube of textile fabric having one end thereof drawn into folds and extended into the body ortion of said tube, a suspending string of folded end of said bag and projecting throu h the other end thereof, the last-mengigied end of said tube being also drawn'into o 5, ing the folds on the last-mentioned end of said tube for closing the same, said suspending string extendlng through said metal strip, that (portion of said suspending string which is isposed within said tube being shorter than the len h of the latter- 2. -In a tea-cartri ge according toclaim 1, said suspending string extending slidably through said metal. strip.
