I
Figs. 10 to 14 illustrate a method of manufacture of the tea package. The layer II is formed with the pleats 40 as shown in Fig. 10. The pleated layer It is formed in the roll 52. A strip of material to form the layer l2 has temporarily glued thereto at spaced intervals the pieces I adapted to form the pocket zit for receiving the spoon, and the strip I! with the pieces l0 thereon is formed into a roll 54. The strips are fed from the roll as shown in Fig. 14 and the first operation is to apply the stitching I8 by the needle 56. The next operation is to stamp out the package in the elliptical shape by the stamping members 58. As shown in Fig. 12, a package has been stamped out from the opening 60. The package, after being stamped out, is shown in Fig. 13 and indicated 62. The pocket I8 may be then readily filled with the tea or other material, the pleated form of the layer It permitting opening of the mouth of the pocket to receive a filling member. After the packages have been filled the securing tab is attached by a staple or other form of attachment.
Instead of cutting and temporarily attaching the pieces ID to the strip l2, the layer l0 could be fed from a roll at a right angle to the feed of the strips l2 and H and the: package could be stamped out at the point where the three layers are sewed or secured together.
The material or substance contained in the package is preferably tea leaves, but cofi'ee, cocoa or other materials which infuse or dissolve when immersed into a liquid could be similarly packaged and applied to a spoon to be used in the same manner. The tea package or infusion package may be readily placed on the spoon by pulling on the tab 26 as the spoon is inserted in the open pocket 20. As illustrated, various means may be used to more securely hold the package on the spoon while in use but such means must permit ready separation of the package from the spoon after use. As disclosed, the fingers need only grasp the tab to remove the package from the spoon. The top of the package may be extended if desired so that the material which is used to form the tab does not become immersed in the liquid. The improved tea package enables obtaining the desired strength of the tea in a more convenient manner and is much more desirable than the old fashionedtea bag which is merely dropped into the cup of liquid, since unless the tea is stirred while infusion is taking place it cannot be ascertained whether the tea is getting too strong. With my package the tea is stirred while infusion is taking place and the spoon with the tea package may be immediately removed from the liquid when the desired strength of tea is obtained.
1. A tea package comprising three layers of liquid permeable material two of which are secured together at the marginal edges to form a chamber adapted toretain the tea leaves, the third layer being attached at its side edges to the other layers, the chamber portion of the package being adapted to fit in the bowl of a spoon and to be retained on the spoon by the third layer extending over the back of the spoon.
2. A tea package substantially elliptical in shape comprising three layers, one of the outer layers being of liquid permeable material, all three of said layers being secured together at their marginal edges from the bottom of the packageup to a point beyond the middle, the outer permeable layer being secured to the middle layer at the top of the package to form a chamber adapted to retain the tea leaves, the top edge of the other of the outer layers being unse cured to the middle layer whereby a pocket is formed adapted to receive a spoon to carry the tea package. I
3. A tea package comprising a bag portion of flexible material adapted to retain tea leaves shaped to fit in the bowl of a conventional spoon, the neck of said bag having a pair of fiexible fingers adapted to engage the handle of the spoon to retain the tea package on the spoon whileinuse. I
4. A tea package comprising a bag portion adapted to retain the tea leaves shaped to fit the bowl of a spoon, a flap-attached to said bag portion adapted to extend over the back of the spoon, the neck of said bag portion being provided with additional means adapted to engage the handle of the spoon whereby the tea package is retained on the spoon while in use.
5. An infusion package adapted to be immersed in a liquid while carried by a conventional spoon comprising a closed bag portion containing material capable of being infused into the liquid, said bag portion having flexible liquid permeable walls, said bag portion having an oval shape adapted to fit into the bowl portion of a conventional spoon, and a flexible strip attached to the sides of said bag portion and arranged to extend over the back of the bowl of the spoon to hold the package on the spoon while immersed in the liquid.
