METHOD OF PACKETING TEA. OR THE LIKE.
Application filed November 1, 1921. Serial No. 512,161.
To all whom it may concern:
Be it known that I, SIMON Coornn, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements'in Methods of Packeting Tea or the like, of which the following is a specification.
This invention relates to the packetlng of materials, to a new and improved form of packet, and particularly to a method for facilitating and increasing the speed of production of packets of a general type such as is used in packeting tea in individual containers.
In a companion application Serial No. 454,707 filed March 23, 1921., there is d1sclosed and claimed a packet for tea or other material formed of a'blank folded on itself and stitched along the meeting edges. The blanks for such packets are individually formed and individually operated on in the making of the packets. In the present invention an elongated blank is used which is folded longitudinally on itself and, by a series of stitching and charging or filling operations, a series or succession of filled packets is rapidly produced in the blank or strip of material, the individual packets being separated from each other only after they have been completely formed and filled as indicated.
By this method of producing the filled,
" increased over the production of packets or containers of a similar general nature heretofore known in the art. In addition the packet forming operations are more easily and economically accomplished and a practical and inexpensive packet is obtained.
Other features of the invention will be hereinafter referred to.
In the drawings in which two preferred forms of the invention are illustrated.
Figure 1 is a view in plan of a suitable blank and showing the progress of a series of operations thereon to convert the blank into a plurality'of packets for tea or other material.
Figure 2 is a view in side elevation of a completed filled packet.
Figure 3 is a view in cross-section taken on the line 3-3 of Figure 1 and showing the operation of fillin or charging one of the packet sections of t e blank median line 6 to bring the two plies of the strip thus formed into superposed relation with their free edges in or substantially in allnement or engagement with each other as at '7 in the drawings. The longitudinally folded blank or strip thus provided is formed into a series or succession of packet form ng sections by the simple operation of running transverse lines of stitches across the folded strip of material between the lateral edges thereof as at 8 in Figure 1 of the drawing. The section of the strip which 1s thus'formed has, as will be clear,
a closed edge formed by the fold in the folded strip and two closed sides formed by the two lines 8 of stitching as indicated.
The fourth side of the packet is similarly closed by a line of stitching such as is indicated at 9 in Figure 1 of the drawing.
The stitching operation may be performed by first forming the two transverse lines 8 of stitching when thetea or other material is charged or filled into the packet through the remaining open edge formed by the free edges of the plies of the strip. The filling operation having been performed, the open side of the packet may be.closed by then running the third line of stitching 9 along the edge and along the two transverse lines of stitching 8.
A preferred way, however, of performing the operation of forming the packets is indicated in Figure 1 of the drawing. In this method of operation the operation of stitching is begun at an upper right-hand corner of a packet section as at 10 in Figure 1 of the drawing and proceeded with to form the first transverse lines of stitching 8. The line 8 having been completed, the stitched line 9 is then produced, the line being extended to a point beyond the mass of tea or other material 11 which has been charged or filled into place previous to the I beginning of the stitching operation.

The operation just described is repeated again and again to enclose each individual massof tea ll in the series of charges that are fed into position'between the plies ofthe blank at the proper intervals through the operationof a sultable filling machine spout is indicated at 12 In the. form of. the invention meats in Figure 1 the individual packets formed etile inateri I charges'offilling material between the plies of the blank atone section thereof and runare square or substantially square in conformation. It will be clear that the particu- 1 lar shapeaswell as the particular size of the packets-1c n be varied between wide limits within he invention. a Another 'desirable form for packets suitable for holding tea is that shown'in Figure '5 of the drawing in which it will be seen that the transverse lines of stitching' 8 which are produced in the blank 5 haveaninclined or oblique position as contrasted with lines of stitching Sin Figure 1 which are substantiall perpendicular to the lateral edges of the b ank.

That method of producing a filled packet which consists in preparing a folded blank of textile material with a charge of hlling material contained between the plies of the fold, and running a line of, stitching from the folded edge of the blank around the charge of material. and back to the folded edge.
4. That method of producing a filled tea rectangular blank of open-mesh fabric with a charge of tea contained between the plies of'the fold, running a line of stitching from edge, and then extending the stitching thread and attaching it to a tag element.
