(Cl. 20G-41) 3 Claims.

This invention relates to tobacco pouches and has particular reference to pouches which are made of relatively cheap materials such as wax or rubber-impregnated paper and are thrown away after use. Such pouches, as now made, are far from satisfactory since they tear easily at the upper corners of the tobacco-receiving pocket andbecome unfit for use before they are emptied of their contents.

The object ofthe present invention is to provide a wax or rubber-impregnated paper pouch in which the upper edge of the frontwall and the upper corner portions of the tobacco-receiving pocket` are strengthened so that they constitute the strongest portions of the. pouch and will withstand, without tearing, the lstrains to which they are subjected in the ordinary usage of the pouch.

According to this invention the upperA edge of the front wall of the tobacco-receiving pocket is reinforced throughout its entire length by a reinforcing element having extended end portions which are bent inwardly and secured to the rear pocket-forming wall o'f the Apouch to reinforce and strengthen the upper corner portions of the pocket. This reinforcing element may be formed as an integral part of the blank from which the pouch ismade or it may consist of a separate reinforcing strip of Cellophane vor other suitable material having a higher tear resistance than the wax or rubber-impregnated blank from which the pouch is formed.

Several examples of the invention are illustrated by the accompanying drawings, in which- Fig. 1 is a front view of a tobacco pouch in which the pocket-reinforcing element constitutes an integral part of the blank from which the pouch is formed.

Fig. 10 is a front view of pouch inwhich a separately formed pocket-reinforcing element is folded over the upper edge of the front wall of the tobacco-receiving pocket andls provided with extended corner-reinforcing end portions secured to the rearwall of t-he pocket.

Fig. 11 is a sectional view'taken along the line i2-I2 of Fig. 10.

'I'he pouch shown in Figs. 1 yto 4 inclusive comprises a tobacco-receiving pocket 6 and a closure iap 6. The pocket B is formed by front and rear walls 1 and l integrally joined at their lower edges and -adhesively secured together at their side edges. The ilap '6 is formed .as an in tegral continuation of the upper edge of the rear pocket-forming wall I and is adapted to be folded around the pocket portion of the pouch in the usual manner. 'I'lie front pocket-forming wall 1 is folded to provide a two-ply upper edge consisting of the outer and inner plies 9 and il. These plies are formed so that they conjointly present extended two-ply end portions Ii which,

asshown in Fig. 2, are folded around the sides of the pocket 5 and adhesively secured to the outer surface of the rear pocket-,forming wail 8 to strengthen vthe upper corner portions of the pocket. While the extended comer-reinforcing end portions Ii of the two-ply upper -edge portion of the pocket-forming wall 1 are preferably secured to the outer surface of therear wall l, it will be understood that, if desired, said cornerreiniorcing end portions ii may be bent inwardly and secured to the front surface df the rear pocket-forming wall I. The front pocket-forming lwall 1 is provided with inturned side edges 1a which are adhesively secured to the rea-r surface of said wall and to the front surfaces of similar inturned side edges 8a of the rear pocket-forming wall l. The ap 6 is formed with intumed side edges 6a which are adhesively secured to the body of the ap and form integral continuations of the inturned side edges of the rear` -aiurther form of also creased vertically as indicated at C and D, the marginal portions of the blank lying outside these creases being folded inwardly to provide the aforesaid inturned side edges of the pocketforming walls l and 8 and the ilap 6. Near its lower end the blank is provided with slits I4 extending outwardly from the vertical creases C and D. The portion of the blank lying below these slits is bisected by a horizontal crease E along which it; is folded to provide the aforesaid two-ply upper edge portion and corner-reinforcing extensions of the front pocket-forming wall 1.

The pouch shown in Figures 6 to 9 inclusive is strengthened by a separately formed reinforcing strip 25 which extends across theouter surface of the front pocket-forming wall 'l at or adjacent the upper edge of said-wall and is provided with extended end portions 26 which are bent around the sides of the pocket and secured to the outer surface of the rear wall 8. This separately formed reinforcing strip 25 is preferably made of cellophane but may be made of other materials. The extended ends of the separately formed reinforcing strip 25 may, if desired, be turned inwardly between the walls 1 and 8 and secured to the front surface of the'wall 1.

The pouch shown in Figs. l and 11 is also provided' with a separately formed reinforcing strip 28 but, in this case, the reinforcing strip is relatively wide and is folded about the upper edge of the pocket-forming walls 'l and 8 to provide inner and outer reinforcing plies 29 and 30 which are integrally united at their upper edges provided with inturned side edges which are adand are adhesively secured to the front and rear surfaces of the interposed pocket-forming wall 1. The folded type reinforcing strip shown in Figs. 10 and 11 is provided with two-ply end portions 32 which are turned inwardly and secured to the outer surface of the pocket-forming wall 1. It will be understood, however, that the extended end portions 32 of the reinforcing strip shown in Figs. 10 and 11 may also be turned inwardly and secured to the inner or front side of the rear pocket-forming wall 8.

Having thus described what I now consider to be the preferred embodiments of my invention it will be understood that I reserve the right to all modifications that fall within the scope and hesively secured together in face to face relation, said front pocket-forming wall being provided with a. reinforced upper edge having extended endI portions which are bent inwardly to overlie and to be adhesively secured to the outer or rear surface of the rear pocket-forming wall 2. A pouch as set forth in claim 1 in Iwhich the material of the pouch is folded upon itself at the upper edge of the front pocket-forming wall to provide the aforesaid reinforced upper edge.

3. A pouch as set forth in claim 1 in which a separately formed reinforcing element is folded over the upper edge of said front pocket-forming wall to provide the aforesaid reinforced upper edge.
