Description
April 28', 1925.
H. LEFRAK INFUSION CARTRIDGE Filed May 9, 1924 H |VENTOR A RNEY Patented Apr. 28, 1925.
UNITED STATES HARRIS LEFRAK, OF NEW YORK, N. Y.
INFUSION CARTRIDGE.
Application filed May 9,
To all whom it may concern:
I, HARRIS LEFRAK, a citizen of the United States, and a resident of the county of the Bronx, city of New York, and State of New York, have invented a new Infusion Cartridge, of which the following is a full, clear, and exact description.
My invention relates to infusion cartridges in which the envelope which carries the material from which the infusion is to be made, is of a textile fabric, easily permeable, with means for securely closing it so that the same cannot be opened without destroying the fabric of the envelope, thereby rendering the same non-refillable.
Another object of the invention is to pro vide an infus on cart-ridge which can be cheaply manufactured.
In the drawing appended to the specification,
Figure 1 is an elevation of an infusion cartridge in which the mouth of the envelope is sealed by a thread,
Figure 2 is a section on line '22, Figure 1,
Figure 3 is an elevation of an infusion cartridge, the mouth of the envelope of which is sealed by a staple,
Figure 4: is a section on line l l, Figure 3, and
Figure 5 is a fragmentary section of a modified arrangement for retaining the string.
Referring to Figures 1 and 2. 5 is the envelope made in the shape of a bag, from suitable textible fabric. \Vhen it is filled, for example with the proper amount of tea, for which this type of envelope is mostly used, the mouth of the bag is closed by folding the bag at the mouth and circling or tying it with a string 6. The bag is then stitched by a thread 7, which thread, as will be seen from Figure 2, pierces the fabric of the bag and passes over the string 6, thereby permanently closing and sealing the envelope 1924. Serial No. 711,964.
and firmly securing the string. The string is the means for handling the cartridge and also serves as a support for a tag 10.
In Flgures 3 and 4, the bag 5, after its mouth is folded and circled by the string 6', l
is permanently closed by a staple 8 which is made to straddle the string which encompasses the bag before it is forced across the folds through the fabric of the bag and the protruding ends 9 of the staple are then bent over the string 6 on the opposite side of the bag.
The type of ferineture shown in Figures 1 and 2 is used for a better grade of tea, since many consumers object to the introduction of metal in the pot Where the infusion is tobe made.
It is self evident that the staple used, as illustrated in Figures 3 and 4,, is of a noneorrosive material and sterilized before the same is applied to the envelope containing the matter from which the infusion is to be made.
In Figure 5 the folded mouth of the bag 5 is directly pierced by the staple 8 and the string 6" is retained by the folds by simply inserting it under the staple while the staple is forced through the folds of the fabric to lock and seal the mouth of the bag. In other words, in the modification shown in Figure 5 the string is not drawn around the folds but simply lead against them and retained thereat by the staple that pierces the fabric and retains the fold of the bag in closed position.
I claim:
An infusion cartridge comprising a textile fabric bag, a string closing the mouth of the bag by drawing it into folds. and means piercing the folds of the fabric of the bag at the mouth and straddling the string on opposite side of the folds.
Sworn to before me this 5th day of May,
HARRIS LEFRAK.
