INTEGRAL CREPED WADDING CONTAINER AND EXPANDER Filed July 12, 196e EXPANDED WADDING United States Patent O 3,498,519 INTEGRAL CREPED WADDING CONTAINER AND EXPANDER Bernard G. Johnson, Neenah, Wis., assignor to Kimberly- Clark Corporation, Neenah, Wis., a corporation of Delaware Filed July 12, 1968, Ser. No. 744,376

Int. Cl. B65d 5/72 U.S. Cl. 229-7 2 Claims ABSTRACT F THE DISCLOSURE A carton having top, bottom and vertically extending walls forming an enclosure and ilap means lying in a plane beneath the top wall and including flaps spaced apart in the front to back direction of the carton to form a dispensing slot. The top wall has a slit co-extensive with the dispensing slot to communicate the interior of the carton to the exterior through the top wall. Sheets or batts of creped wadding compressed endwise, retained within the carton in substantially continuous lengths, may be withdrawn through the dispensing slot to expand the wadding to material of low density from higher density and material of high bulk from a lower bulk.

BACKGROUND OF THE INVENTION Field of the invention This invention relates to a carton construction which is particularly intended as a creped wadding expander device.

The invention and the prior art- Many products such as wall insulation, packaging, cushion material, base material for sanitary napkins and the like use creped tissue wadding as a prime component. Such wadding contains one or more, and very often a considerable multiplicity, of plies. It is known ton compress sheets or batts of such wadding endwise to a small fraction of their original ilength while the sheet or batt thickness remains substantially constant. The sheet density increases and the bulk decreases; such action permits storing and shipping of the creped wadding in a limited space. The user may re-expand the wadding. Prior art devices for this purpose are useful; this invention provides a device for effecting re-expansion which may be carried out manually, which minimizes dusting and which may be carried out on relatively small quantities of the wadding in a very economical manner.

More specifically, this invention provides a shipping carton provided with ap means which lie beneath the usual top wall of the shipping carton. The ap means are spaced apart in the front to back direction of the carton to form a dispensing slot which communicates with a slit in a top wall. The creped wadding stored within the carton is drawn lengthwise through the slot and is engaged frictionally by the flap means to effect a longitudinal drawing and reexpansion of the compressed creped wadding. To inhibit binding of the wadding in the withdrawal, the end walls of the carton have notches communicating with the slot so that la'ny tendency of the compressed wadding to bind endwise is overcome.

The invention will be more fully understood from the following detailed description and accompanying drawings wherein:

PIG. 1 is a perspective view of a carton in accordance with the invention with the top wall portions raised to more clearly illustrate novel features of the invention;

FIG. 2 is a view illustrating particularly an arrangement of ap means with the top wall removed; and

3,498,519 Patented Mar. 3, 1970 lCC FIG. 3 is a sectional view illustrating the method of carton use, a number of compressed wadding plies being shown within the carton. l

Referring to the drawings, the numeral 1 generally designates a carton formed in accordance with the invention. The basic carton construction is well known, forms no part of the present invention and, accordingly, is illustrated and discussed only in suicient detail to provide a complete understanding of this invention.

Carton 1 is of any suitable material such as pulp board. The carton includes vertically extending

end walls

2, 3. A vertically extending front wall is shown at 4 and a back wall at 5. The necessary bottom wall is indicated at 6. The top wall in this preferred embodiment is provided by

wall sections

7, 8.

Wall sections

7, 8 in FIG. 1 are shown as drawn back; in FIG. 3 they are shown in position for carton use, that is, brought together over the ilap means provided in accordance with this invention.

The flap means in the preferred embodiment shown incl-ude aps or

flap portions

9, 10, 11 and 12. Each llap portion is united integrally with an end wall. I have found that it is preferable to provide the flap portions so that they form a longitudinal wadding dispensing slot 13 closely adjacent a longitudinal wall of the carton such as wall 4. For this purpose I provide flap portions 9, 10 to be each of greater dimension widthwise of the carton than flap portions 11, 12. Also, the ilap portion 9 terminates short of the flap portion 12 in the width direction to provide for slot 13. Flap portion 10 is similarly related to flap portion 11. Thus, in effect, the ap means are spaced apart in the front to back direction of the carton to form the dispensing slot; the slot width is readily provided as desired in the cutting of the carton stock flaps so that the compressed wadding will be sufbject to frictional engagement by the apmeans when the wadding is drawn through the slot. Such engagement stretches out the crepe wadding as indicated generally in FIG. 3; in effect, the creped hill and valley nature of the wadding becomes more aparent to the eye as the wadding is withdrawn.

The

flap portions

9, 10, 11 and 12 are integral with end walls of the carton and the carton may be formed from a at blank'in a single operation, if desired. The ap portions hinge or pivot on the end walls and each has an inner free end as designated at 9', 10', 11' and 12 (FIG. 2). These free ends form a front to back opening 14 which, as shown in the drawings, intersects slot 13 at substantially right angles. The flap portions thus have a degree of freedom and aid in maintaining adequate tension on material passing through slot 13. The

top portions

7, 8 secured in customary manner limit the movement of the flap portions.

The package of compressed wadding indicated generally at 15 in FIG. 3 has been partially dispensed and the drawing is somewhat idealized for clarity. The material 13 is withdrawn in the direction of the arrow. Importantly, the creped and compressed wadding, when withdrawn, does not significantly project dust or nes into the air; the fine material tends to be retained within the carton thereby providing an unexpected benefit.

The crepe compressed wadding may tend to shift in the widthdrawal action. This may occur for any of a number of reasons including the particular withdrawal action, the original packing of the compressed wadding and the like. To aid withdrawal I have provided in the

end walls

2, 3

notches

16, 17 which communicate with the slot 13 at either end of the carton. Shifting of the wadding then does not cause abutment of the end walls and binding which would lead to undue tension, dusting and the like.

Withdrawal may also be aided in some instances by simply turning the box up or on a side; gravity then may aid withdrawal by changing the angle of approach of the wadding to the slot 13.

What is claimed is:

1. A carton having top, bottom and vertically extending walls forming an enclosure, the vertically extending walls including front, back and end walls, ap means projecting parallel to the front and back walls and arranged to lie in a plane beneath the top wall, said flap means including aps spaced apart in the front to back direction of the carton to form a dispensing slot so that material drawn through the slot may be subjected to frictional engagement by the flap means, said top wall having a slit coextensive with said dispensing slot, and said carton having a notch formed in each of opposed end walls of the carton .4 communicating with the dispensing slot formed by the ap means.

2. A carton according to claim 1 in which the notch formed in an end Wall is of generally rectangular shape.
