2 Claims. (Cl.

This invention relates to a collapsible carton and is particularly designed'for use as a tobacco carton of the type heretofore usually manufactured o! tin or similar metal and comprising a An object of the .invention is to provide a carton of this type comprising the advantages of the tin box or carton and other advantages .not possessed by the latter,.suchfas cheapness and eiliciency of manufacture, light weight, collapsibility for shipment, etc.

Another object is the provision of a carton of this kind which possesses ample strength and rigidity so as to remain intact and serviceable during any period of normal use.

These and other objects are attained by the means described herein and illustrated in the laccompanying drawing, in which:

Fig. 1 is a plan view of the blank out o! which the carton of this invention is formed, the score lines in this and other views being indicated by dotted lines and cuts being indicated by full lines.

Fig. 2 is a perspective view ofv a complete carton in closed position.

Fig. 3 is a cross-sectional view on the line 3-3 of Fig. 2.

Fig. 4 is a perspective view of the completed carton with the top in open position.

Fig. 5 is a plan view o! the carton in collapsed position, just prior to complete flattening.

Fig. 6 is a cross-sectional view on the line 6-6 oi Fig. 5.

In greater detail and with reference to the A carton of this invention is formed of an elongated blank which is cut and scored to provide an inner rear wall I3 and an inner side wall II joined thereto 'along a score line I2. An inner front wall I3 is joined to side wall I I along score line I4. Another inner side wall I5 :loins the inner front wall I3 along the score line I8. An intermediate rear wall I1 is joined to the inner sidewall I5 along score line I3 and outer side wall I9 is joined, along score line 20, to the wail I1 and to thewall I3 is connected the outer iront wall 2I, along a score line 22. An-

' other outer end wall 23 is joined to the outer front wall along the score line 24 and, finally, an outer rear wall" 25 joins the side wall 23 along the score line 23.

The intermediate wall I1 and the outer front l wall 2l are each provided with closure naps 21 2l and 29-30, respectively, and the outer side walls I9 and 23 are formed with closure tabs 3|-,-32 and 33-34, respectively. These naps and ltop of the outer rear wall 25.

tabs, it will be noted, are cut clear at their ends for independent hinge action. The wall I1 is scored adjacentvthe top and bottom, as indicated l at 35 and 36, along the hinge lines of said closure naps. Wall I1 is further scored at 31 for defining. along with the score line 35, one ofthe rear elements 38 of a hinged closure, as will be further described. The side elements of the said hinged closure are indicated at 33 and 40 (Fig. 1).

The outer front wall 2l and the outer side wallsA I9 and 23 are cut through, as indicated at 4I, 42 and 43, the cut 43 beingcontiguous at one end with the score line 31 of the wall I1 and the cut 42, at one end, being continguous with ascore line 49, the latter being provided adjacent the The blank so formed and cut is initially laid out flat, as seen in Fig. 1. The undersideof the wall I0, as seen in Fig. l, may have a glue strip The wall I0 is now bent I2 over upon the inner end front wall I3. The doubled now carried over by 44 applied thereto. along the score line wall I I and the inner parts just mentioned are bending along the score line I6 anddisposed against the intermediate wall I1 and the glue strip 44 fastens the inner rear wall I0 to the intermediatey wall I1. A

In this connection a novelmanufacturing detail may be described, namely, the notch 45 provided at the top of said wall I0 in alignment with the glue strip 44. If this portion of wall I0 were not notched, the glue strip, as applied by the usual mechanically operated glue wheel or the like, would extend clear to the top of the vwall I0, which wall portion would therefore, upon the foflding operation above described, become secured to 'a movable part 38 of the hinged cover to be formed, precluding operation of the latter.

The blank is now further bent along the score line 20 and again along the score line 24. The face of the outer rear wall 25, as seen in Fig. l, has. prior to this last mentioned operation, been provided with a glue strip 46 and when the said wall is carried around to its final position against the outer face of the intermediate wall I1, it is glued thereto and likewise to the closure element 3 8 (Fig. 3).

The carton is now in shipping condition, as

substantially indicated in Figs. 5 and 6. Ob V ation of the completion cycle is the bending parts. Needless to say, the filling voperation may be performed at either end of the carton.l

The completed commercial package has now been prepared except for suitable wrapping which may be provided as desired.

When the user purchases a commodity such as tobacco packed in a carton of this invention.

it is merely necessary for him to bend backwardly the topportion of the carton as seen in Fig. 2 to the position seen in Fig. 4, the hinged movement being eiected along the

score lines

49 and 31, as seen in Fig. 3.

It will be seen that in effect the present invention provides an outer casing having a body and l a hinged top and enclosing an inner casing which projects above said body to be frictionally embraced by said top when the carton is. closed.

For ease in operation, the inner front wall I3 is cut atthe top, along the line 41, and the adjacent corners of the side walls Il and I5 are rounded as at 48 (Fg.'4) so that the hinged cover slips into and out of pla'ce without interference. The carton itself as well as the manufacturing details disclosed, including the initial glueing operation above described, are believed to represent a substantial advance in the art. Modifications will suggest themselves uponconsideration of the present disclosure but these are believed to be comprised within the spirit and scope of the invention. v v

What is claimed is:

1. In a carton, an inner wall, an outer wall overlying the inner wall, an integral hinge element formed on the outer wall, the inner wall in that portion thereof overlaid by the hinge element being provided with a notch of a depth equivalent to the width of said hinge element, and a glue y material.

strip applied to the inner wall prior to juxtaposition of said .two walls and extending across said innerwall to the inner end only of said notch whereby, upon such juxtaposition, said hinge element is left free for 'operation relative to the inner wall.

2. The process of connecting together in overlying relationship a pair of similar-sized sections of sheet material while maintaining said sections independent along one edge portion, the process comprising making a notch across the proposed independent portion of one of said sections, applying a glue strip to the face of said one section in alignment with said notch and extending only to the inner end of the notch, and placing the glue-carrying face of said one section in aligned contact with a face of the other section of sheet FRANK A.
