Application September 23, 1947, Serial No. 775,699

3 Claims.

This invention relates to new and useful improvements in tea bags and the primary feature of the present invention is to provide a tea bag including suspension cords interlaced in such a manner with the bag as to permit the bag to be compressed for expelling liquid therefrom as the cords are pulled outwardly in an opposite direction.

Another important feature of the present invention is to provide a tea bag adapted to eliminate the usual drippings prevalent when such a bag is withdrawn from a cup of hot water.

A further feature of the present invention is to provide a tea bag which is simple and practical for use, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a perspective view of one side of the tea bag;

Figure 2 is a perspective view of the other side of the tea bag showing the manner in which the bag is compressed;

Figure 3 is an enlarged sectional view taken on line 3-3 of Figure 1;

Figure 4 is an enlarged sectional view taken on line 4-4 of Figure 1; and

Figure 5 is a top plan view of the bag in an unfolded position.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is shown a preferred embodiment of the present invention, the numeral l0 represents generally a tea bag formed from a substantially rectangular member [2 of any suitable conventional type of known tea bag material, folded transversely along dotted lines H, see Figure 5.

A plurality of marginal folds I6 are made along the dotted lines l8, for retaining said edges in a folded position to each other. Pockets 20 are preferably formed at the lower corners. Tea or the like 22 is placed in the bag and the free edges 23 of the bag are folded and clamped together by staples or the like 24.

A suspension cord 26 is extended through the bag I0 adjacent edges 23. This cord 26 includes a pair of spaced portions that extend in spaced parallelism along one side of the bag to the lower portion of the bag, and are joined adjacent the lower portion of the bag by a horizontal member, as best seen in Figure 4 of the drawings. As usual, an identifying tag 28 is carried by the suspension cord, facilitating handling of the bag.

When the tea bag is withdrawn from a cup of hot water, it is merely necessary to pull the two upwardly extending ends of the suspension cord outwardly in an opposite direction which will force the upper portion of the bag upon the lower portion thereof thereby expelling the liquid from the bag, as best shown in Figure 2 of the drawings.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what claimed as new is:

1. A tea bag of permeable, compressible and collapsible material, and a suspension cord interlaced with said bag and extending through the lower portion thereof, said cord forming a loop above the bag, the upper portion of said bag being received on said cord and slidable thereon toward the lower portion of said bag for compressing said bag to expel liquid therefrom as said loop is pulled apart.

2. A tea bag of permeable, compressible and collapsible material, and a suspension cord interlaced with said bag and extending through the lower portion thereof, the part of said cord interlaced with said bag having two parallel portions which are connected at their lower ends by a horizontal portion, the upper ends of the parallel portions comprising supporting means for carrying the bag in a non-compressed arrangement when extended vertically from said parallel portions and comprising means for collapsing and compressing the bag when subjected to force laterally and oppositely directed.

3. In a tea bag of permeable, compressible and collapsible material, a bag support and compressihg means comprising, a single loop having spaced portions extending longitudinally of the bag and disposed on the outside of said bag from adjacent the top to the bottom thereof, the upper parts of said portions being extended through WILLIAM R. SHAW.
