13 Claims.

My present invention relates generally to dispensing devices, and has particular reference to a device for dispensing a stack of paper sheets or the like.

The present construction is designed primarily for use by retail dispensers of food commodities, such as delicatessen stores, the intention being that the user will have readily available a series of sheets of paper or the like, such as greaseproof paper, to be used in wrapping the commodities.

It is a primary object to provide a dispensing unit which is disposable in its entirety after all the sheets of an accommodated stack have been r used up, whereby there will be no necessity for mounting a relatively permanent box or cabinet nor for periodically refilling the same.

With this primary object in View, it is a particular featureof my invention to provide an arrangement of parts which permits the container or box to be inexpensively manufactured of cardboard or equivalent material.

Nevertheless, certain features of my invention are not necessarily restricted to the employment of a disposable box of cardboard or the like, and certain advantageous features of the present construction may ,find wider applicability in connection with relatively permanent metal cabinets or boxes.

In the preferred embodiment herein illustrated and hereinafter to be described, a box of cardboard is so constructed that it may be manufactured sufficiently inexpensively to permit its sale along with an accommodated stack of sheets, without materially increasing the cost of the unit; and to permit the box subsequently to be disposed of in its entirety. Preferably, the box is composed of a single element of cardboard out and folded to permit it to be set up into substantially rectangular form. 5

One of the features of the present construction lies in the arrangement of an outlet opening near the upper front edge of the box, together with means for accommodating a stack of sheets in an upwardly arched position so that the sheets may be drawn successively in an upwardly oblique forward direction through the outlet opening.

More particularly, my construction provides for a base having a-rearwardly declining rear portion for supporting the stack in upwardly arched condition, and a yieldable follower adapted to press downwardly upon the stack. Where the box is made of cardboard the follower may constitute an integral portion of the top wall, and may advantageously be shaped to define a V cross-section.

The present box is further characterized by a front wall provided with a recess narrower than the stack of sheets and exposing the front of the stack for the full depth of the latter. The front wall thus prevents intentional or accidental withdrawal of the sheets through the front wall, yet permits each successive sheet of the stack to be manually grasped for withdrawal purposes through the outlet opening.

Another important feature 'of my invention lies in the provision of a stack of sheets each of which is folded to define a Z cross-section, the sheets being nevertheless free of interengagement with one another. This desirable objective is accomplished by constructing each sheet with the body of the 2 longer than the combined lengths of the Z ends. A stack of sheets thus free of interengagement is relatively simple to manufacture, involving no unusually complicated machinery, and the stack itself is a compact rectangular unit.

The reason why I am enabled to employ sheets 25 of this character is that the box is so constructed and arranged that the withdrawal of each sheet has a tendency automatically to bring about an interengagement of the sheet with the ensuing sheet, thereby positioning the next sheet in .30 readily graspable position. This operation will be more fully set forth hereinafter.

I achieve the foregoing objects, and such other objects as may hereinafter appear or be pointed out, in the manner illustratively exemplified in the accompanying drawings, wherein- Figure 1 is a perspective view of a dispensing unit constructed in accordance with the present invention;

Figure 2 is a plan View thereof, with the stack of sheets omitted;

Figure 3 is a cross-sectional viewtaken substantially along the line 3-3 of Figure 1;

Figure 4 is a perspective view of one sheet of the stack of sheets;

Figure 5 is a fragmentary cross-sectional view, similar to Figure 3, on an enlarged and somewhat exaggerated scale to indicate the mode of use;

Figure 6 is an exaggerated cross-sectional view showing the normal relationship of the sheetsin the stack;

Figure '7 is a plan view of the blank from which the box may be constructed; and

Figure 8 is a perspective view of a preferred construction of a unit as it appears when it is manufactured.

In the preferred construction, the box is composed of an integral blank of cardboard or the like initially shaped, cut, and scored substantially as shown in Figure '7. Referring to this figure, it will be observed that the body portion of the blank is divided by transverse score lines III, II, l2, l3, l4, and I5 into a series of adjacent sections l6, |8, I9, 28, 2|, and 22. The sections Iii-2|! are substantially rectangular, whereas the sections 2| and 22 are trapezoidal.

Extending laterally from the section l8 are the sections 23 and 24 connected to the section I8 at the score lines 25 and 26, respectively. The sections 23 and 24 carry the additional lateral flaps 21 and 28.

Extending laterally from the section I9 are the sections 29 and 30 connected to the section |9 by the score lines 3| and 32.

Extending laterally from the section 26 are the sections 33 and 34 connected to the section 20 by the score lines 35 and 36.

Extending forwardly from the sections 33 and 34 are the front sections 31 and 38, these sections having the oblique edges 39 and 48 and being secured to the sections 33 and 34 along the score lines 4| and 42.

The sections 3'! and 38 carry the triangular fiaps 45 and 46.

Furthermore, the sections 31 and 38 carry the small lateral tabs 41 and 48 secured to the sections 31 and 38 along the score lines 49 and 50.

In setting up the box, the section 20 defines a substantially rectangular bottom and the section I9 is folded upwardly to define the back wall. The sections 29 and 3|] are arranged in parallel relationship along the score lines 35 and 36, respectively, and the sections 33 and 34 are then bent upwardly to define the sides of the box.

The section |8 is then swung forwardly along the score line l2 so as to define a top wall, and the sections 23 and 24 are folded down over the sections 33 and 34. The attachment sections 28 and 27 are then turned inwardly beneath the bottom wall of the box and are adhesively or otherwise secured in this position.

As thus far described, the box comprises a bottom wall and a top wall, a back wall, and two sides; and whereas I have described one way of setting up a structure of this kind, it will be understood that my invention is not necessarily restricted to the particular method of folding or assembly.

It should be noted, however, that in accordance with my invention the top wall i8 is not as deep as the bottom wall 26, the forward edge of the top wall (defined'by the score line H) lying slightly to the rear of the forward edge l4 of the bottom wall 20.

The sections l1 and I6 are then doubled 'upon themselves, as shown most clearly in Figures 3 and 5, to define a yieldable follower of substantially V cross-section, the apex of the V (defined by the score line l) extending rearwardly. Because of the inherent resilience of cardboard or its equivalent, this V-shaped follower extends rearwardly downwardly into the box and is" adapted to exert a highly emcient yieldable pressure in a downward and forward direction upon the stack of sheets accommodated in the box.

In completing the initial set-up of the box, the sections 2| and 22 are folded upwardly along the lines I4 and I so that the section 22 ultimately defines a rearwardly decliningrear portion of a base, as shown most clearly in Figure 3; the section 2| defining a downwardly sloping front portion of the base.

The assembly is then completed by swinging the sections 31 and 38 into alignment, the flaps 45 and 46 being positioned beneath the box and secured by adhesive means or otherwise. The sections 3'! and 38 thereby define a front wall having a recess, this recess in the illustrated embodiment being substantially V-shaped, as shown most clearly in Figure l.

The flaps 41 and 48 are then bent rearwardly into the plane of the top wall l8.

The result is that an outlet opening is defined immediately in front of the forward edge ll of the top of the box, this outlet opening being of the full width of the box. In this connection, it should be observed that the recess in the front wall is of less width than the box.

It will be understood that the unit, during its assembly, is caused to accommodate a stack of sheets, this stack being designated generally by the reference numeral 53. The stack rests upon the base 2|-22 and is yieldably pressed down by the follower |6-||, the stack thus assuming an upwardly arching position, as shown most clearly in Figure 3. The forward face of the stack is partially exposed for its full depth through the recess in the front wall.

Preferably, when the box is constructed, the original blank is provided with an extension divided by the score line 60 into two additional panels 6| and 62, whereby the panel 6| may be arranged at the forward portion of the top to seal the outlet opening, and the panel 62 may be arranged to cross the front wall to conceal the latter. A removable sticker or tab 63 holds the free edge of the panel 62 in position. Thus, the box may be manufactured, stacked, stored, and shipped in a completely sealed condition.

When it is ready for use, the sticker 63 is removed or mutilated, and the panels 62 and 6| are bodily severed from the box along the score lines 64, thus leaving the unit in the condition illustrated in Figures 1-3 and 5.

Preferably, but not necessarily, the forward edge of the section I6 is concaved, as at 65.

It may be pointed out that the relative sizes of the sections shown in Figure 7 are not exactly in accord with the relative sizes of the corresponding sections shown in set-up condition in the other figures; nor are the other figures in entire accord. Thus, in Figure 3, the back wall H3 is somewhat longer, relative to the bottom wall 28, than the relationship between the sections H3 and 20 in Figures 1 and 7. These discrepancies arise because of the desire to illustrate the invention in a campact manner. The relative proportions of the parts are, therefore, not to be gauged too accurately from the drawings themselves.

Before describing the manner in which the device is used, reference will be had to Figures 4 and 6. In Figure 4, a single sheet of. the stack 53 is designated by the reference numeral 54. This sheet has a cross-section conforming substantially to the letter Z. I have designated the body of the Z by the reference numeral 55 and the 2 ends by the reference numerals 56 and 51. It will be observed that the length of the body 55 is greater than the combined lengths of the Z ends 56 and 57. As a result, a plurality of these sheets may be stacked, as shown in Figure 6, without any interengagement between the sheets.

Preferably, but not necessarily, there is a score line 58 near and parallel to the free edge 59 of the portion 57. This score line 58 has the tendency to induce a slight elevation of the edge 59.

It will further be observed that the curved position of the sheets will induce a slight elevation of the edge 59.

It will also be observed that the sections 51 of the sheets are somewhat shorter than the sections 56; and that when the stack is accommodated in the box the sections 5'? are arranged forwardly.

In use, the person desiring to withdraw a sheet from the unit has ready access to the uppermost sheet through the recess in the front wall. He merely grasps the elevated portion 5? (see Figure 3) and pulls the sheet upwards and forwardly through the outlet opening, as shown in Figure -5. This operation not only straightens out the sheet to destroy its 2 cross-section, but it also has the effect of causing a temporary interengagement between the portions 56 and 51 of the ensuing sheet. This temporary interengagement is shown most clearly in Figure 5. Accordingly, as the sheet is withdrawn from the unit it not only straightens itself out, ready for use in wrapping a commodity, but it also elevates the section 51 of the ensuing sheet to facilitate the subsequent grasp of the ensuing sheet when the operation is repeated.

As the sheets are withdrawn, the depth of the stack decreases and the yieldable follower continues to press down upon the decreasing stack to hold the remaining sheets in proper position.

Ultimately, after all the sheets have been withdrawn, the empty box may be discarded and another complete unit may be substituted.

Obviously, the various features of the present invention are not necessarily restricted to a box that is made of cardboard, although, as hereinbefore stated, the invention is peculiarly adapt able for embodiment in a cardboard box.

Moreover, it will be understood that certain phases of the invention do not require that the sheets be of Z-shaped cross-section, nor that they necessarily be of greaseproof paper. The invention may find wider applicability in the dispensing of sheets of differing characteristics for various purposes.

In general, it will be understood that changes in the details, herein described and illustrated for the purpose of explaining the nature of my invention, may be made by those skilled in the art without departing from the spirit and scope of the invention as expressed in the appended claims. It is, therefore, intended that these details be interpreted as illustrative, and not in a limiting sense.
