This invention relates to improvements in tobacco pouches and has particular reference to a pouch made from layers of pouch material adhesively secured together along marginal edges, and having a reinforcing band to hold the seam and pouch structure intact.

In the manufacture of tobacco pouches of this general type it is desirable to have a pouch which will permit an end-to-end opening of the pouch so that the hand as well as a pipe can easily be inserted without fear of seam separation or tearing. Attempts to avoid mutilations of the pouch have resulted in constructions which narrow the opening therein and this tends to encourage rather than to prevent seam separation and tearing. One of the most practical seam constructions thus far developed is a bellows type where an end-to-end opening is permitted but because the hand and a pipe can so freely be inserted into the pouch there still remains some danger of seam separation.

A general object of the invention is the provi sion of a tobacco pouch which will overcome the foregoing difliculties and disadvantages, which is economic of manufacture, pleasing in appearance and well suited to the purposes for which it is intended.

A principal object of the invention is the provision of a bellows type of tobacco pouch having a reinforcing band inconspicuously applied to the pouch to hold the seam structure as well as the pouch walls intact.

A further object of the invention is the provision of a tobacco pouch which has a seam and pouch reinforcing band adhesively applied across the front of the pouch and which has an adhesive holding bead along its upper edge.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in con nection with the accompanying drawings; in which:

Fig. 1 is a plan view illustrating a preferred form of a web or blank of pouch forming material;

Fig. 2 is a plan view of the web shown in Fig. 1

marginally folded over with a suitable applica- 1 tion of adhesive thereon;

Fig. 3 is a plan view of the blank of Fig. 2 folded and adhesively secured into a pouch;

Fig, 4 is a plan view of the pouch shown in- Fig. 3 with a reinforcing band applied thereto;

Fig. '7 is a perspective view of a fragmentary portion taken along the line 1-1 of Fig, 6 and ginal portions come together in face-to-face conlooking in the direction of the arrows; and

Fig. 8 is a perspective view of a fragmentary portion of one end of a closed pouch.

Referring more particularly to the drawings there isillustrated at Fig, 1 a web or blank of pouch material which preferably is of a duplex type. Briefly, such a blank is made by marginally securing together two webs of material as they are continuously run in superposed position from mill rolls, one of the webs having an application of adhesive marginally applied thereto. One web may be made, for example, of Glassine to form the inner liner of a pouch. The other web forming the outer covering of the pouch may be made of a transparent material such as Cellophane which has on one surface a suitable design or other printed matter applied by the method known as "reverse printing. The adhesive and printing ink can be applied in any suitable manner such as, for example, by means of a gravure press in which the printing ink and adhesive each is applied to separate etched rollers, wiped by a doctor blade and the adhesive. or ink transferred to the selected web.

After such a web is fabricated it may be cut into blanks as shown in Fig. 1 or, before cutting, may be given opposite marginal folds III as illustrated in Fig. 2. These marginal folds lie against the surface forming the inner pouch lining I I. If the web is continuously folded before being out into blanks a stripe or other suitable application of adhesive I2 is applied intermittently along the exposed marginal surfaces as indicated.

The end of the blank containing the adhesive is then folded over upon itself so that the martact and in this manner a pouch portion l3 with adhesively secured marginal seams is formed. .A pouch cover is provided by the remaining extension I4.

After the formation of the adhesive seam, a reinforcing band I5 is secured to the front of the pouch with ends I! extending around the back of the pouch. This reinforcing band has applied thereto an adhesive l8 which can be similar to that which is used in forming the marginal seams for the pouch. There is always the undesirable possibility that at some time during its manufacture or subsequent use the adhesive may leak past the edge of the pouch across the lip at the opening and even get into the contents of the pouch. To prevent this. the band or tape I5 is provided at its upper edge with a bead I! formed by a marginal fold of the band which, in addition to reinforcing the band, acts as a seal or dam to prevent the escape of the adhesive.

A primary function of the reinforcing band is to prevent the seam construction from separating during use. It will be observed by reference-to Fig. 6 that the seam which is formed is of a bellows type. Opposite marginal faces Ill-Ill, while they are adhesively secured together, permit the entire pouch to be opened from one corner to the other. As heretofore indicated, this not only adds to the capacity of the pouch but permits more readily the insertion of the hand especially when holding a pipe. Short reinforcing strips around each seam could also be used but the single long strip is preferable.

It will thus be seen that the objects hereinbefore set forth may readily and efllciently be attained, and since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in, a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A tobacco pouch, which comprises a web of pouch material marginally folded back upon itself at opposite sides against an inner lining for the pouch, each marginal fold having a stripe of adhesive along a portion of its exposed surface. one end of said web being folded upon itself with said adhesive surfaces secured to each other where they are in face-to-face contact to form an ad'- hesively secured seam for said pouch extending from the resulting mouth opening of the pouch to its bottom and a cover member for said pouch. and a seam reinforcing band secured across the front of the pouch adjacent the opening and continuing across each seam joint to the rear of the pouch to hold the seam pouch structure intact while permitting maximum end-to-end opening of the pouch. said cover member extending across said band.

2. A tobacco pouch, which comprises a laminated blank of pouch material having opposite marginal portions folded against an inner lining of the pouch, each of the marginal portions having adhesive along its exposed marginal surface, one end of the blank being folded upon itself with the adhesive marginal portions secured to each other to provide the pouch with adhesively secured seams extending from the opening of the pouch to its bottom, and a reinforcing tape having an adhesive thereon secured to said pouch, said tape having an adhesive holding head on its adhesive containing surface and being secured to the pouch with the bead extending along the lip of the pouch and around the lateral edges of the seams to hold the pouch and seams intact while permitting maximum edge-to-edge opening of the pouch and to prevent escape of adhesive to the lip of the pouch and contents.

3. A tobacco pouch, which comprises a laminated blank of pouch material having opposite marginal portions folded against an inner lining of the pouch, each of the marginal portions having adhesive along its e posed marginal surface. one end of the blank being folded upon itself with the adhesive marginal portions secured to each other to provide the pouch with adhesively secured seams extending from the mouth opening of the pouch to its bottom, and a reinforcing tape marginally turned over upon itself along its upper edge and adhesively secured across the front of the pouch below its opening and extending around the seams and secured to the back of the pouch. 4. In a pouch structure of the kind described made from a blank of material folded over upon itself and adhesively seamed marginally in this position leaving a pouch opening, the improvement which comprises a tape having an adhesive thereon secured to such a pouch, said tape having an adhesive holding head on its adhesive applied surface along the upper edge of said tape and secured to the pouch with said bead disposed below the pouch opening and around the lateral edges ofvthe seams to hold the pouch structure and scams intact while permitting maximum edge-to-edge opening along the mouth of the pouch and to prevent the escape of adhesive to the mouth opening and lip of the pouch.

. 5. A tobacco pouch, which comprises a cut web of pouch material having opposite marginal sections folded against a face forming an inner liner for said pouch, each of said marginal sections having adhesive along a portion of its exposed surface, one end of said web being folded upon itself with said adhesive applied marginal sections being secured to each other to form a pouch having front and rear walls with an adhesively secured seam extending from the mouth opening of the pouch to its bottom and with a cover extending from the mouth in the opposite direction, and a seam reinforcing member secured to said pouch with its upper edge lying along the upper edge of the front wall and free of said cover to maintainthe pouch opening and encompassing the lateral edges of said seam and being secured to the front and the rear walls of said pouch to hold said pouch structure intact, said cover being foldable over said mouth as a closure and overlying said reinforcing member.

6. In a tobacco pouch made from a blank of material folded over upon itself and adhesively seamed marginally in this position to provide front and rear pouch walls leaving a pouch opening, the improvement which comprises a nonfibrous reinforcing strip secured to the front wall of'said pouch'with an upper edge thereof lying along the marginal edge of the front wall defining the mouth opening and encompassing the lateral edges of its seam from the front wall to the rear wall to hold said pouch structure intact while permitting maximum edge-to-edge opening along the mouth of the pouch.
