Unite States Patent F PAPERBOARD TOBACCO POUCH William A. Ringler, Wayne, Pa., assignor, by mesne assignments, to The Diamond Match Company, New York, N. Y., a corporation of Delaware Application March 13, 1956, Serial No. 571,188

Claims. (Cl. 20641.1)

My invention relates to a packaging structure and more particularly to a package in which a sales unit of smoking tobacco may be packed for sale to the consumer, the package in the hands of the consumer forming a convenient pouch from which the tobacco may be readily dispensed.

It is a principal object of my invention to provide a tobacco pouch composed of a paperboard carton and an inner wrapper or packet in which the tobacco is packed, the carton being so constructed and arranged that its opposed walls will' flex outwardly so that the tobacco may be readily dispensed from the pouch.

A further object of my invention is the provision of a tobacco pouch of the character described incorporating a top closure which provides a pouring spout for the tobacco when the front and rear walls of the pouch are expanded; the said top closure, when in closed position, having a flap portion thereof fitted between the front wall of the pouch and an inner front wall to lock the walls of the pouch against displacement to their expanded dispensing position. p

A further object of my invention is the provision of a pouch of the character described which may be readily fabricated from a one-piece cut and scored paperboard blank utilizing conventional folding and gluing equipment.

Still a further object of my invention is the provision of a dispensing tobacco pouch in which the tobacco is packed in a moisture-proof liner which may be readily opened for use.

The foregoing as well as other objects of my invention which will appear hereinafter or which will be apparent to the skilled worker in the art upon reading these specifications, I accomplish by those constructions and arrangements of parts of which I shall now describe certain exemplary embodiments. p

Reference is now made to the accompanying'drawings wherein:

Referring first to Figure 1 of the drawings, I have therein illustrated a paperboard blank for forming my tobacco pouch, the blank being cut and scored to provide an outer end wall 1, outer front wall 2, outer end wall 3, and rear wall 4 in side-by-side articulation in the order named. Projecting outwardly from the free side edge of the rear wall is an inner end wall 5, an inner front wall 6 and an inner end wall 7. All of the parts thus far described are preferably of equal depth with the exception of the outer front wall 2 which is cut away along its upper edge, as indicated by the reference numeral 8. Diagonal score lines 9 and 10 extend through the rear wall 4, the score lines starting at the lower corners of the rear wall and meeting at a point of juncture midway between the ends of the top edge of the rear wall. Corresponding diagonal score lines 11 and 12 are formed in the inner front wall'6 and these score lines are adapted, in the erected structure, to coincide with diagonal score lines 13 and 14 formed in the outer front wall 2.

A top closure member 15 is articulated to the upper edge of the rear wall 4 and the closure member carries a relatively deep tuck flap 16. A score line 17 bisects the top closure member and tuck flap, the score line projecting outwardly from the point of juncture of the diagonal score lines 9 and 10. The top closure may also include narrow closure flaps 18 and 19 connected to the upper edges of the outer end walls 1 and 3, respectively. The bottom closure is composed of seal end flaps 20 and 21 articulated to the lower endsof the walls 2 and 4, respectively, and narrow seal end flaps 22 and 23 articulated to the lower ends of the end walls 1 and 3, respectively.

The blank just described may be conveniently assembled by first applying adhesive to the under surfaces of the inner end walls 5 and 7, such adhesive being indicated by the shaded areas 24 and 25 seen in Figure 2. There after, the blank is folded along the line of articulationbetween inner end wall 5 and inner front wall 6, the parts thus assuming the position illustrated in Figure 3. The blank is next folded along the line of articulation between outer end wall 3 and rear wall 4, thus bringing the parts to the position illustrated in Figure 4 in which position the inner end wall 7 is juxtaposed to the outer end wall 3 with the adhesive 25 interposed therebetween. The outer end wall 1 is folded to overlie the inner end wall 5 carrying the adhesive area 24. The structure may then be tubed to bring it to the condition illustrated in Figure 5.

The completed pouch with its top closure in open position is illustrated in Figure 6. It will be understood,- of course, that subsequent to the tubing of the blank;

the inner front wall6 is juxtaposed to the outer front wall"2"with the diagonal'score lines 11," Band '12, 14 coinciding. The cut away area 8 of the outer front wall exposes .a portion of the inner front wall 6 and enables the user to readily insert the tuck flap 16 "between-the inner and outer front walls, as illustrated in dotted lines in Figure 7, to close the pouch.

Figure 8illustrates a tobacco wrapper or packet 26 in which the tobacco is sealed. In the embodiment illustrated the packet is of generally rectangular configura-. tio'n corresponding to the dimensions of the pouch and of asize to be received therein, in the manner best seen in Figure 9. The materialfrom which the wrapper .or packet is formed does not constitute a limitation on my invention, and diverse. materials may be employed,'. as is wellwithin the ken of the skilled'worker in the art. Preferably,;the packet. will be formed from a moisture proof material and will be sealed so. as to prevent the exchange of air from the inslde to theoutside of the packet, thereby maintainingthe' tobacco in fresh condition. The top wall 27 of the packet may be provided with a longitudinally extending line for severance 28 by means of whichthe packet may be readily opened for use by running a knife blade or other sharp object along the line for severance.

In use, the pouch is opened by first. lifting. the top closure and severing the packet along the line for severance 28, whereupon inwardly directed pressure isapplied to the end'walls of the pouch, as indicated by the arrows A in Figure 9. The inwardly directed pressure on the end walls will cause the front and rear walls to buckle or expand outwardly along their diagonal score lines, thus opening up the pouch in the manner illustrated in Figure 10. It will be noted that the inner and outer front walls buckle .01" fold together along their coinciding diagonal score lines; and the folding of the rear wall 4 along its diagonal score lines 9 and 10 results in the transverse folding of the top closure member and.

tuck flap 16 along the medial score line 17. It will be noted that the packet or wrapper expands along with the front and rear walls as the ends of the pouch are compressed, thereby providing ready access to the supply of tobacco.

Referring now to Figure 17 of the drawings, itwill be evident that the medially folded top closure member 15 and tuck flap 16 will provide a convenient pouring spout or filling member by means of which the tobacco may be filled directly into a pipe. By the same token, when the front and rear walls of the pouch are expanded, it

isv also possible for the user to insert the, pipe29-directly.

into the supply of tobacco, as illustrated in Figure 18, the expanded condition of the, front and rear walls providing ample room within the pouch for the insertion of the pipe. I

Subsequent to the filling ofthe pipe, the pouch may be reclosed by releasing the end walls andpressing inwardly on the front and rear walls, thus causing the latter walls to return to substantially planar condition. The closure flaps may then be infolded and the tuck flap 16 fitted between-the inner and outer front walls to close the pouch. It should be pointed out that'when the tuck flap 16 is fitted between the inner and outer front walls, the. walls are locked against displacement along their diagonal score lines and hencethe walls of the pouch cannot be accidentally displaced and the contents spilled. Figures 11, 12 and 13 illustrate a modification of my tobacco pouch wherein, for purposes of simplicity,'lil-:e

parts have been given like reference numerals; In this,

embodiment the seal end flaps 20 and- 21 are replaced by a bottom closure flap articulated to the lower edge of "rear wall 4, the. bottom closure flap carrying-a tuck flap 31 which is'adapted, in the erected structure, to be inserted between the lower edges-of the "outer and inner fr'ontwalls -2'and 6,'respectively, as-will be-clearly apparent from Figures 12' and 13; This arrangement ist advantageous in that it eliminates the bottom sealing operation and, at the same time, the sandwiching of the tuck flap 31 between the juxtaposed front wall panels provides a suitably tight closure.

Figures 14, 15 and 16 illustrate a convenient form of tobacco packet provided with a tear tape extending along its upper edge by means of which the packet may be readily opened. The packet may be conveniently formed by tubing a web of packet forming material 32, the web first having applied thereto a continuous length of tear tape material 33, the tear tape being positioned with respect to the side edges of the .web so that it will lie along what will be the uppermost portion of the resultant tube. The web of material, upon being tubed by bringing its opposite edges together to form a longitudinal seam 34, may then be filled with increments of tobacco separated by the transversely sealed areas 35, as seen in Figure 15. The individual packets may then be separated in the seam areas and fed into the paperboard pouches,

as will be readily understood by the skilled worker inthe art. Here again the nature of the packet forming material does not constitute a limitation on my invention, although it will be preferably of a heat scalable nature so that the closure seams may be readily formed in a rapid and continuous operation.

Modifications may, of course, be made in my invention without departing from the spirit of it. Having, however, described my invention in certain exemplary embodiments, what I desire to secure and protect by Letters Patent is:
