8 Claims. 1

This invention relates to cartons made of cardboard, or other foldable fibrous material, cut, scored and folded to form a strong, moistureresisting container for ice cream or other solid or semi-solid contents and comprising eflicient. means for stripping the container walls in successive sections, to expose the contents in unwrapped condition for ready access thereto, as particularly convenient in retail or home dispensing of the contents.

One object of the invention is to provide a container of the above character having a strong and highly insulated construction combined with eiiective and convenient provisions for stripping of! successive portions of the container walls to expose successive zones of the contents in unwrapped condition for ready removal and service in limited quantities.

Another object is to provide such a container having inner and outer, or double walls for strength and insulation, so constructed that the double walls may be conveniently stripped off in successive sections to expose successive zones of the contents in unwrapped condition and adapted to be readily cut off with a knife, for example, for distribution inlimited portions.

Another object is to provide a container of the above nature comprising an auxiliary cover for closing the end of the carton after its integral closure flaps have been removed by the stripping of! of one or more wall sections.

A further object is to provide such a carton and auxiliary cover so folded and glued as to becapable of collapsing into flat shape for convenience in storage and transportation in quantities.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

Fig. 15 shows the band fully removed to expos a zone of the contents;

Fig. 16 shows the remainder of the container with the auxiliary cover in place;

Fig. 17 is a sectional plan view through the container and contents, and

Fig. 18 is an enlarged'sectional view on the line i8al8a in Fig. 15.

The embodiment of the invention herein disclosed, by way of illustration, comprises, preferably, a one-piece blank (Fig. 1), cut and scored to form an inner set of four" rectangular side walls, 20 to 23, inclusive, separated by spaced, scored fold lines, 24, 25 and 28, and also an outer set of rectangular side walls, 21 to 30, inclusive, separated from each other by spaced score lines, 3|, 32 and 33. The two sets of walls are separated by ascored fold line 34 lying adjacent the center of the blank, as shown. The scoring of these folding lines may be accomplished by indenting the material from one or both sides, as at 35 (Fig. 9), although it is preferred to additionally weaken the lines 24 and 26 to facilitate the folding of the material at such lines, for a purpose hereafter described, this additional weakening being preferably accomplished by intermittent cuts .or slits 36 extendingentirely through the material.

The inner side wall 20 at one end of the blank is preferably extended laterally to provide a securing strip 31 having a scored fold line 38 provided with a glued area 39. At the opposite end of the blank the outer side wall 39 is extended to provide a securing strip 40 separated by a scored fold line 4| and provided with a glued area 42 spaced inwardly from the free lateral edge of the strip 40, so as to leave terminal portions or tabs 43 separated by fold lines 44, for a purpose hereafter described. At 45 is a score line preferably made by a slit extending part way through the material so as to effect a discontinuance. of the surface fibers. At 45a is a similar score line out partially through the material from the opposite surface of the blank for a purpose hereafter described.

The side walls to 23, inclusive, of the inner set are extended at their opposite ends to form flaps, 46 to 49, inclusive, and 50 to 53. inclusive, respectively, these flaps serving to provide an inner closure for each end of the carton.

The side walls, 27 to 30, inclusive, of the outer set are likewise extended at their opposite ends to provide end closure flaps, 54 to 57, inclusive, and 58 to 6|, inclusive, respectively. The end flaps 54 and 58 are each formed with a pair of spaced angular slits 52 for interlocking cooperation with tongues 63 on the end flaps 56 and 60, for locking all of the end flaps in closed position.

Extending laterally across all of the side walls ar a plurality of lines of scoring 64, spaced equally from one another endwise of the carton, as shown. These lines are preferably made by intermittent short slits 85 extending through the material with further weakening of it by more widely spaced and longer slits 6B. The slits 66 in the outer side walls 21 to 30, inclusive, are preferably staggered with relation to the similar slits in the inner side walls, to more effectively seal in the contents. These lines of scoring 64 divide the material into a series of elongated sections or bands, as 61, each terminating at one end in one of the tabs 43 referred to above.

In the folding and gluing of the blank, the inner set of side walls, shown at the left in Fig. l, are folded about the line 34 so as to overlie the outer set of side walls 2'! to 39, inclusive, as shown in Fig. 5, except that the inner side wall 20 is folded back about the line 24 to overlie the inner wall 2|, as shown in Figs. 5 and 7. The walls 23 and 21 are then folded about the score lines 26, and 3i so as to overlap the glued strip 31, by which the wall 20 is secured and sealed to the wall 23, as shown in Figs. 6 and 8. Thereafter the side wall 30 is folded about the line 33 so that its glued strip 40 overlaps the wall 27 and is adhesively secured and sealed thereto by the glued area 42, but leaving the tabs 43 free so that they can be grasped in the fingers.

The blank is arranged, by the above steps, into a collapsed tubular shape, convenient for storage and transportation, as shown in Fig. 10, and may be readily erected into the rectangular shape shown in Fig. 11. In this shape, one end of the tube is closed by folding in the opposite pairs of flaps, 50 to 53, inclusive, of the inner side walls, after which the fiaps 59 and iii of the outer walls are folded in, followed by closing of the fiaps 5B and 60 and the interlocking of the same by inserting the tongue 63 in the slits 62. The container may then be filled at its other end with ice cream, or other contents, after which the filling end is similarly closed, the container and contents being then as shown in Fig. 12. The

side walls of the outer set are preferably made somewhat wider than the corresponding inner side walls to provide extra material for the folding of the outer side walls around the inner walls, as indicated in Fig. 5, and, similarly, the line of folding of the outer closure fiaps is preferably slightly elevated above the line of folding of the inner flaps for thesame purpose. It is apparent from the above description that the invention provides a double walled construction of the general type disclosed in my Patent No. 2,348,070,

in which both the side and end Walls are of double thickness, affording strength and stiffness and a high degree of insulation, as desired in cartons for holding ice cream.

In dispensing the contents of the container, at retail or in home use, the closure flaps at one end of the carton are opened and the freely projecting tab 43 of the first side wall section or band 61 is grasped in the fingers and pulled to tear the band along the adjacent score line 64, first from each of the outer side walls in succession, until the center fold 34 isreached and then from each of the inner side walls, one after another, as indicated in Fig. 14, until the band is entirely stripped from the carton and contents, as indicated in Fig. 15, leaving a zone 68 of the contents in unwrapped condition so as to be ac cessible for slicing or cutting off with a knife. Each of the remaining bands may be successively removed in the same fashion, to unwrap successive zones of the contents, as desired in serving the same for use, but leaving the unused portions of the contents, from time to time, still contained in the remaining portions of the carton.

It will be noted that the central folded portion of the blank and the blank ends overlapped and glued thereto are disposed at one of the corners of the carton, this arrangement serving to further strengthen and stiffen the construction. At the same time, the location of these overlapping glued parts adjacent a corner of the carton serves to better support them during the tearing of each band, first from its glued attachment to the folded central portion and then the tearing of the folded central portion from the inner wall 20. as shown in Fig. 14. The severing of the surface fibers by the scores 45 and 45a serves to terminate such fibers and prevent any peeling of the surface portions beyond such scored lines. After the carton has been opened and a portion of its contents removed, as described, the end of the carton so opened is closed by an auxiliary cover 89 (Figs. 2 to 4, inclusive, and 16). This closure is preferably made of a one-piece blank of foldable material, as shown in Fig. 2, comprising marginal, scored fold lines 10 forming opposite pairs of side walls H to 14, inclusive. The walls 13 and 14 have end flaps I5 separated from them by folding scored lines 16 and provided with adhesive, as indicated by stippling. The side walls H and 12 are erected as shown in Fig. 3, and the walls 13 and 14 are then erected and their flaps l5 folded about the corners thus formed and adhesively secured to the walls H and 12, as shown. The walls 13 and 14 are provided with inclined scored folding lines 11, so that the side walls may all be collapsed on the body portion as shown in Fig. 4, for disposing the cover in fiat shape for storage and transportation. In use, the side walls are erected, as in Fig. 3, and the cover thus arranged is placed over the open end of the carton to protect the contents, as shown in Fig. 16.

The invention thus provides a container hav- QJOQJSS otherwise removed from the main body of the g contents. The stripping bands in the outer wall portion are protected by the inner walls from deterioration by moisture, so that they may be readily torn along the scored lines, while the torn edge thus formed serves as a guide in the tearing of each strip from the inner walls which are in contact with the material. may be maintained in closed condition by the auxiliary cover provided and such features afford a highly efilcient, convenient and satisfactory type of container for ice cream and similar materials.

It will thus be seen that the invention accomplishes its objects and while it has been herein described by reference to the details of a preferred embodiment, it is to be understood that such description is intended in an illustrative, rather than in a limiting sense, as it is contemplated that various modifications in the construction and arrangement of the parts will readily occur to those skilled in the art, within the spirit of the invention and the scope of the appended claims.
