8 Claims.

This invention relates to an article and method of manufacture, having particular reference to a merchandising packet constituting an improved type of pouch structure containing tobacco, for example, formed by folding and sealing sheet material in a novel manner, and the provision of such an article and method of manufacturing the same is a principal object of the invention.

More specifically, it is an object of the invention to provide such a merchandising packet by folding and sealing sheet material into a tube, transversely heat-sealing the tube marginally along one of its ends, transversely perforating one side wall of the tube beyond the filled body member to facilitate severing of the side wall to provide a mouth opening for the pouch to obtain access to the commodity, lling a substantial portion of the tube constituting the pouch section above the heat-seal and below the perforation with the commodity to form the body member of the packet, and securing the remaining portion of the tube in face-to-face relationship to provide a protective and stiffening cover nap to be folded and preferably secured against the body member.

Another object of the invention is to provide such a packet in which that portion of the tube constituting the cover flap beyond the perforated wall is secured in face-to-face relationship by being heat-sealed together transversely in a section lying adjacent the transverse perforation, and the end of the tube being transversely heatsealed along its marginal edge to provide a prctective and stiffened cover ap.

It is also an object of the invention to provide a container for such a merchandising packet by folding and sealing a wrapper preferably into a gusseted container and forming a pouch opening therein, perforating one of the side walls of the tube as Well as adjacent gusseted portions to facilitate severing of the side wallsand gussets to obtain access to the commodity.

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

The invention accordingly comprises the several steps and the relation of one or more of such steps with respect to each of the others, and the article possessing the features, properties, and the relation of elements, which are exemplified in the following detailed disclosure, 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 (Cl. 20G-48.5)

connection with the accompanying drawings, in which:

Fig. 1 is a perspective view illustrating a sheet of perforated heat-scalable material folded into a tube and transversely sealed at its lower marginal end to provide a pouch;

Fig. 2 is a perspective view of the pouch of Fig. 1 with the walls expanded to receive a commodity such as tobacco;

Fig. 3 is a perspective view of the pouch of Fig. 2 filled and heat-sealed to provide a cover flap;

Fig. 4 is a perspective view of the completed pouch with the cover flap folded into position to provide a merchandising packet constituting a tobacco pouch;

Fig. 5 is a perspective view of the pouch unfolded and opened along the perforated side wall for access to the commodity; and

Fig. 6 is a transverse section of a fragment of sheet material preferably used in the formation of the packet.

Referring more particularly to the drawings, there is indicated generally at Ill a pouch, formed from a heat-sealable web having l laminated thereto an outer protective sheet to provide a wrapper for the commodity, the wrapper being folded in such a manner that the heat-scalable web provides the inside liner for the pouch.

In Fig. 6 there is illustrated a heat-scalable web ll laminated to an outer protective sheet l2 preferably by means of a micro-crystalline or amorphous wax I3. The heat-scalable material may be a rubber hydrochloride film, such as pliolm, or a cellulose lm, such as cellophane, which has been treated for heat-sealing by means of, for example, a heat-sealing lacquer. The outer protective covering l2 preferably is a sheet of glass'ine or may be any other suitable material, such as kraft paper, foil, or the like.

Such a sheet is folded into tubular formation so that longitudinal marginal edges overlap to be heat-sealed to provide a longitudinal seam I4. One end of the tube is transversely heat-sealed marginally to provide a heat-sealed bottom I5 to form the tube l0.

One side wall of the tube is weakened, as by a transverse perforation I6, to facilitate severing of the side wall to provide a mouth opening for the pouch to obtain access to the commodity as will more fully appear hereinafter.

It should be noted that a gusseted tube is illustrated and that the perforations extend through the gussets. However, the invention is equally applicable to a fiat or envelope type of arrangement but the gusseted type is preferable.

section lying between it and perforation is defines me top or me pouch the heat-sealed bottom I5. The tube in this perforated condition is substantially filled above the heat-seal I to approximately the perforation point I6 and the commodity therein expands the side walls of the tube to form the body member I1 of the packet. After the pouch has thus been filled with a desirable commodity, such as tobacco, it is heatsealed beyond the perforated portion to bring the remaining end of the tube walls into faceto-face relationship, as indicated generally at I8, thereby to provide a protective and stiffened cover fiap to be folded and preferably secured against the body member.

Preferably the remaining portion of the tube beyond the perforation I6 is sealed together transversely in a section I9 lying adjacent the perforation I6. The entire portion I8 which forms the cover ap can be sealed but this is unrl necessary and, therefore, only a marginal transverse heat-seal of the other extreme end of the tube 20 is provided. This prevents separation of the flap when tle same is in use.

After the tube has thus been fllled and sealed, the cover fiap I8 is wrapped around the body member I1. The cover may be sealed to an opposite side wall of the body member such as, for example, by means of a tax stamp.

When the packet has been merchandised and ready for use, it is but necessary to break the stamp and unfold the cover flap I8 lifting the same to the position shown in Fig. 5. By pressing against and running the finger, or finger nail, along the perforated portion of the tube transversely thereof the side wall in this area can be severed, thus providing a mouth opening for the pouch whereby readily to obtain access to the commodity contained therein. After use the wrapper can easily be folded back to its original position to maintain the rest of the contents of the packet intact.

A laminated sheet composed of materials described in connection with Fig. 6 preferably is used in practicing the invention. The adhesive material I3 which preferably is a micro-crystalline or amorphous wax is put on rather heavily. The reason for this is not only to provide the necessary adhesiveness whereby the heat-sealable web and the outer protective sheet are maintained in laminated position, but to provide a barrier against moisture-vapor transmission. In addition to this, such a laminated sheet has the advantage of imparting to the pouch a leathery or metallic feel and this is very desirable. It should also be understood, however, that while a laminated sheet has been disclosed, the invention can be practiced by the use of a. single or duplex web of such a heat-fusible material as rubber hydrochloride, or the like.

Also, while a tax stamp is illustrated as hold-l ing the cover ap in position, it will be understood that the same can be sealed in any other suitable manner.

It will thus be seen that the objects hereinbefore set forth may readily and eiiiciently be attained and since certain changes in carrying out the above method, and certain modifications in the article which embody the invention may be made without departing from its scope, 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 ali statements of the scope of the invention which, -as a matter of language, might be said to fall therebetween.
