5 (Ilaims. (Cl. -206--58) The present invention relates broadly to containers, and in its specific phases to a carton for rolled sheet material, said carton being adapted to support said rolled material from its ends and to facilitate dispensing same while thus supported.

Small rolls containing a few feet of waxed paper, transparent plastic, metal foil and the like, for home use, have long been available in small dispensing cartons upon the bottoms of which the rolls rest. The home and commercial consumption of such rolled sheet materials has so increased that it has become advisable to market them in much larger rolls. However, if such large rolls are laid on their side upon the bottoms of cartons or other hori Zontal supports, pressure-sealing of the convolutions of the wound materials, particularly of the plastic and wax types, frequently occurs due to the Weight of the rolls, and even without pressure-sealing, friction between the side of the roll and the bottom of the carton has a somewhat similar effect in preventing unrolling without ditliculty, and frequently results in tearing the rolled material. Therefore, although much less convenient, it has heretofore been customary to place the large or jumbo rolls upon end. It was a recognition of this problem and the lack of any completely satisfactory solution to same which led to the conception and development of the present invention.

Accordingly among the objects of the present invention is the provision of a new and improved dispensing carton which makes it possible to satisfactorily market the larger rolls of sheet material in horizontal position, while eliminating side friction on the roll and with no danger of the convolutions thereof becoming pressure-sealed together, thus greatly facilitating unrolling and tearing off of such material as required.

In attaining the desired end, it becomes imperative to provide bearing stubs at the ends of the carton upon which to support the relatively large and heavy roll free from friction on the carton bottom. In so doing, a further object of the invention has been to provide a novel end construction for the carton adequately strong to carry the required load, without the necessity of manufacturing the entire carton from very thick and stiff material. To attain this end, a carton has been provided having pluralply end Walls, the plies of which are of the same thick ness as the carton bottom, front wall, and back wall, and novel end-reinforcing members have been provided and which are substantially coextensive with said plural-ply end walls and which members carry the bearing stubs.

A further object has been to provide the outer plies of the carton end walls with novel flaps which are folded inwardly over the upper edges of the other plies and are then folded downwardly and secured against the inner sides of the end-reinforcing members to aid in rigidly securing said end walls and said end-reinforcing members together.

Another object has been to provide each bearing stub in the form of a cup or sleeve which, for instance, may be formed from plastic or stamped metal, and which has ice iatented Mar. 4, 1958 an annular peripheral flange at one end of its side wall, the cup or sleeve being snugly inserted into a suitable opening in the corresponding end-reinforcing member and having its flange confined between this member and the carton end wall.

Still another object has been to provide a novel frontreinforcing member for the carton, the ends of this me'rn' oer being integral with the front edges of the end-reinforcing members, thus anchoring and bracing the latter against warping while stiffening the whole carton.

Yet another object has been to utilize the front reinforcing member as a support for the usual serrated blade commonly used to facilitate tearing of the sheet material when unrolled to any required extent.

A still further object has been to provide a novel cover joined to the top of the carton back wall and having a forwardly declined front edge portion which is biased toward the inner side of the carton front wall below its upper edge to frictionally grip the sheet material as it is Withdrawn between the front edge of said forwardly declined cover portion and said front wall, thus holding the material in convenient readiness for the next unrolling operation.

Yet another object has been to dispose the forwardly declined portion of the cover at a widely obtuse angle to the major portion of said cover, to thereby provide for holding and supporting the sheet material against the front wall of the carton with greater pressure than if a less obtuse angle were employed. This construction also permits the forwardly declined cover portion and the adjacent portion of the carton front wall to coact in forming a carton top channel adequately large to receive a persons fingers, thus facilitating gripping of the free end of the rolled material for withdrawal.

A still further object has been to provide a novel two'- ply construction for the cover to increase its stiffness and resilience, and thereby exert greater holding pressure against the free end of the rolled material so as to avoid accidental rerolling of same after a strip of the rolled stock has been torn off.

Yet another object has been to provide a simple, and relatively inexpensive container construction permitting rapid and easy manufacture from two blanks and two bearing stub members.

Still further objects and advantages of the invention will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention, then, consists of the container means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting forth in detail certain means for carrying out the invention, such disclosed means illustrating, however, but one of various ways in which the principle of the invention may be used.

in the annexed drawings:

Figure l is a perspective view of the blank from which the carton bottom, front and back walls, end walls and cover are formed.

Figure 2 is a perspective view showing the blank from which the end and front reinforcing members are formed, and the two bearing stubs or cups.

Figure '4 is a vertical longitudinal section, partly in elevation, taken on line 4-4 of Figure 3, looking in the direction of the arrows.

Figure 5 is a horizontal longitudinal section, partly in elevation, taken on line 5-5 of Figure 4, looking in the direction of the arrows.

Preferences in the carton structure have been disclosed in the drawings, and will be rather specifically'des'ciib'ei,

butit'is'to be understood that variations within the spirit and scope of'the inventionmay well be made.

7 The blank of Figure 1 will first be described. This .blank is formed from cardboard and comprises a bottom forming'portion' 6, a front wall-forming portion 7, a back ,wall-forming portion 8,'end'wall forming portionsil, 10,

and .11, flap portions 12 011 the edge of portions 11, and V a cover-forming portion generally denoted at 13.

' The bottom-forming portion 6 is joined along score lines 14'tothe front and back wall-forming portions and 8, and'the latter is joined along a score line 15 to the cover-forming portion 13. The end wall-forming portions 9' are joined at score lines 16 -to the bottomforming'portion 6, and the end wall-forming portions 10 and 11 are similarly joined'at 17 and 18 to the front and back-forming

portions

7 and 8,,respe'ctively.

The four end wall-forming portions 10 and 11 are about'square while the other two portions 9 maybe outwardly tapered, as shown, if desired. 'The fiap portions 12 are joined'on score lines 19, aligned withthe score,

line 15, to the end wall-forming portions 11. These'flap ,portions 12 have'score lines 2% near and parallel with .the score lines 19. The free longitudinal edges of the flap portions 12 have notches 21.

The cover-forming portion 13 is of substantially square form and is divided by score lines 21, 22, and 23' into -two

majorrportions

24 and 25 and two minor portions 26 and 27'. When the

portions

25 and 27 are jointly folded on the score line 21 against the two portions24 and 26 respectively, and glued thereto, a two-ply cover is formed and this cover is then bent alongthe lines22,

extending substantially throughout its "length for a purpose to appear. a

In Figure 2, a second blank is shown, said blank being formed from much heavier cardboard, corrugated fiber board, 'chip board or the-like for strength and stiffness. Thisblank is divided by score linesStl into an; elongated major'portion 31 and two substantially square end por- ,tions' 32;. In the completed carton structurepthe portion 3 1 provides a front reinforcing wall'and the two end port ons 32 form end reinforcing walls. Each of these port1ons 32iis formed with a circularsnbstantially central opening 33, and two cylindrical bearing stubs 34 are provided for snug reception in these two openings to rotatably'rnount the roll R by being received in the usual core ltube'T thereofJ 'Each bearing stub 34 maybe in the form of a stamped sheet metal cup having'an annular flange 35 at the free edge of, its side wall 36.

7 of Figure Z is folded on the lines'3 il' to form three integral reinforcing" wallsa front wall 31a formed by the portion 31 and two end walls 324 formed by the portions and'into the ends of the core tube T of the roll R. The assembled roll and reinforcing Walls are then placed upon the bottom-forming portion .6" of Figure l and "the free end E of the sheet material is pulled up above the'wal 31a. Then the portions 9 are upwardly folded against and glued to the end reinforcing .wa1ls'32a to form inner end wall plies9a. y K

The forwardly declined cover portion 13b is at awidely obtuse angle to the major'portion of the cover, and by the inherent resiliency of the material from which the carton is constructed, said portion 13b is forcibly biased toward the front wall 7a. Thus, it firmly holds the free end E of thejrolled material against accidental dropping back into the carton. Moreover, the cover portion; 13b co:

7 acts with the upperportion of the ,front wall 7a in providing an open top channel C ofsuific'ient width and depth to readily receive a persons fingersjf when the material end E is to be grasped for Withdrawal. After pulling out the required amount of material it is easily torn ofi along the serrated tear strip 38 which is sufficiently eX-- edge of front reinforcing wall 31a. 7 a a 1 Rubber strips S are preferably cemented to the carton bottom 6a to prevent it from sliding while the sheetma terial is being pulled from the carton; t
