7 Claims. (Cl. 221-47) This-invention relates generally to folded paper products, such as paper towels, paper napkins and the like and to a dispenser for dispensing such products for use.

In summary, the invention provides a rectangularly shaped paper sheet folded along lines parallel to a diagonal in a manner to form alternately folded diagonally extending panels to thereby provide a folded sheet having accessible triangular tab portions, and capable of being formed, packed and dispensed for unfolding without the necessity of having to intertwine the leaves of the paper for dispensing as is required in prior folded paper products.

More particularly, the diagonally folded paper product of this invention comprises a central panel, a first intervening panel hinged to one edge of said central panel and folded with one face thereof against a face of said central panel, a second intervening panel hinged to the opposite edge of said central panel and folded with one face thereof against the opposite face of said central panel, and a triangularly shaped pull tab panel hinged to each intervening panel and folded against the opposite face of said intervening-panel.

The invention further provides for use with such diagonally folded paper sheets, a slotted dispenser container from which such folded paper sheets may be dispensed merely by grasping a triangular tab portion accessible through a triangular or diamond shaped enlarged opening in the dispenser slot. In combination, the dispenser container and folded paper sheets provide a dispenser container package.

In order that the invention may be more readily understood and carried into effect, reference is made to the accompanying drawings which form a material part of this specification and in which the invention is described with particular reference to folded paper towels. However, the invention is not to be limited to paper towels since its scope is defined by the appended claims rather than by the description preceding them and may encompass all folded paper products when formed and dispensed in accordance therewith.

In the drawings:

Fig. 1 is a partially cut away isometric view'of a dispenser with enclosed diagonally folded paper towels in position for dispensing.

Fig. 2 is a fragmentary sectional view of the dispenser of Fig. 1, taken in the plane of line 2-2 of Fig. 1 but showing only two diagonally folded towels in the container, other towels and elements shown in Fig. 1 being omitted from Fig. 2 for clarity.

I Fig. 3 is a bottom plan view of the container of Fig. 1 showing the dispensing slot with one of its triangular shaped enlargements in registration with a triangular tab portion of a folded paper towel.

Fig. 4 shows a blank fromwhich the folded paper towel of this invention may be formed.

Fig. 5 is a plan view of a paper towel folded in accordance with this invention and adapted to be used in combination with the dispenser as shown in Figs. 1, 2

, 2 a and 3, the relative positions of certain panels and tab portions being shown in phantom lines.

Fig. 6 is a, perspective view of the towel of Fig. 5 showing in phantom lines the relative positions of the various panels and tab portions.

Fig. 7 is an isometric view of a dispenser container package in which diagonally folded towels may be marketed and from which such towels may be dispensed through the tear out portion indicated by dotted lines.

In Fig. 1 a dispenser container package 10 is illustrated as comprising a substantially rectangular box 11 having a removable cover 12. The container is provided with an elongated bottom slot 13 extending longitudinally thereof and having a central enlargement 14 formed by oppositely aligned triangular openings 14' and 14" cut into the edges of such slot. The particular construction of the container is immaterial as long as it has the described slotted bottom arrangement, as any suitable container can be employed.

For the sake of convenience, the enlarged opening 14 formed in the slot 13 by the oppositely aligned triangular cut out portions 14' and 14" is referred to herein as a diamond shaped opening and such term is intended to also cover those cases where the angles at the vertices of such triangular portions are right angles which is the most desirable construction for use with the paper towels of this invention since the triangular tab portions 19 of such towels are right angled themselves. The enlarged opening 14 is centrally positioned in the slot 13 with an axis of the diamond transverse at right angles to the longitudinal axis of such slot.

Folded paper towels 16 stacked in face-to-face relationship are shown as enclosed by the dispenser container 11 and held in position by means of aloosely sliding weight 17. The dispenser container with its contents may be fastened to a wall by any suitable means such as the slot and screw arrangement 18 illustrated.

As shown in Fig. 2, towels 16 are not intertwined, but are merely stacked one on top of the other in face to-face relationship. As hereinafter explained, the manner of folding the towels is such that a triangular tab portion 19 is accessible from either side thereby elimimating the necessity for' always having to position a particular face of the towel down, as each face of the towel is the same as the opposite face. Also, intertwining of the towel panels in order to bring successive towels into registration with the dispensing slot 13 is eliminated. Moreover, there is no need to have a particular end of the towels adjacent a particular end of the container because no matter how the towels are inserted, the diamond shaped opening 14, which extends on both sides of the slot 13, will register with a triangular tab portion 19 of the bottom towel.

Fig. 3 is a bottom plan view of the dispenser container of Fig. l and shows the elongated slot 13 with its enlarged diamond shaped opening 14 in registration with the triangular tab portion 19 by which a towel 16 may be grasped and pulled from the dispenser.

- Fig. 4 shows a blank Sheet from which the towel of this invention may be folded and comprises generally a rectangular blank 21 of any suitable flexible absorbent material, preferably paper, and desirably in theform of a squarefoldable along a plurality of parallel diagonally extending fold-lines, which may be imaginary lines, including a first pair of fold lines 22disposed substantially equi-distant of the diagonal extending between opposite corners of the blank, and a second pair of fold lines 23 parallel .to and disposed substantiallyequidistant outboard of the first pair of fold lines 22. p 1

When the blank is alternately or reversely folded on the

lines

22 and 23, a folded product is formed as shown in Figs. 5 and 6 in"which there is a centralpanel 24 having hingedly connected thereto and reversely and inwardly folded on its opposite faces a pair of intervening diagonally extending parallel panels 25, each of which has hingedly connectedthereto a triangular tab portion-19 formed by rever'sely folding the" eorner portions of the blank sheet-inwardly on such intervening panels 25 along the'outboard yfold'lines 23. Thus," in folding the blank of Fig. 4 alternate reverse folds are made along spaced apart

fold lines

22 and 23,' and oppo-' site panels are folded inwardly on jboth' faces of the central panel 24 with diagonally opposite corners forming triangular tabs 19'which may be readily grasped by fingers for pulling.

As the folded paper towel 16 has its own pull tab 19 adapted to drop 'into accessible position in registration with the diamond shaped opening 14, there is no necessity for intertwining the leaves or panels of successive paper towels 16 stacked in the dispenser container 1-1. Thus, pulling of towels fr'om the dispenser is much simpler because there is far less friction toovercome than with intertwined towels.

Moreover, towels may be placed either-side down and with either end of the towels adjacent either end of the container. Thus, no special technique is involved in loading the dispenser, it being only necessary to place such diagonally folded towels face down in the container with their longitudinal axes substantially parallel to the longitudinal axis of dispensing slot 13. The dispenser container is of proper'length and width to position the towels so that one of their tab portions 19 will register with 011c of the triangularly shaped end portions of 'the enlarged diamond shaped openings 14.

The manner of folding the towel from the blank 21 is important and should be correlated with the size of slot 13, and particularly with the enlarged diamond shaped opening 14 with which the tab portion 19 is to register. i V

In this connection, it is of particularimportance that the width (a) of intervening flaps 25 and the width (b) of the attached tab portion 19 be correlated to the location and size of the enlarged diamond shaped opening 14, so that'the tab 19 will readily fall into accessible position upon reporting to the slot 1 3 inregistration with the diamond shaped opening 14. v In general this is accomplished by making the distance between one side of the dispenser container 11 and the far edge of the elongated slot 13, slightly greater than the width (a) of the intervening panels 25, and at the same time 14 board edges 25' of the intervening panels 25 are also the iuboardedges of the triangular tab portions 19, and

so, in order to insure that such tab portions are free to i fall into accessible positionwhen in registration with the enlarged opening 14, the width (h) of the elongated the total diagonal distance (i) between opposing cormaking the width (b) of the pull tab 19 slightly less than the distance (d) from one end of the diamond shaped opening 14 to the far edge of the elongated. slot 13. This will insure registration of the triangular tab portion 19 with the diamond shaped opening 14 so that such tab portion will fall into position for 'ready access by the fingers of a person desiring to remove a towel from the dispenser.

The width (b) of the-tab portion 19 should 'be .no greater and preferably less than the width (a) of the intervening panel 25 which in turn should ,be not greater and preferably less than the'width (e) of. the central panel 24 so that when folded, the tab 19 will be confined within the edges of the central panel 24 thereby insuring registration of the tab 19 with the diamond shaped opening 14 when the folded towel is positioned fiat in the dispenser container 11. 'It will be noted that when folded as described, thereare five plies in the central portion of thetowel. This forms a central bulge in a stack of such towels which operates to push triangular portions of the towels into the enlarged opening 14.

cordance with the dimensions of the folded product as hereinbefore explained. As a typical example for conventionalsized square paper toweling 011 9% inches each side, width (e) of the central panel is 4 inches, width (a) of each interveningpanel is 2.6 inches, width (b) of the 'tab portion is 2.3 inches, and the width (g) of the overlap or five ply area is 1.2 inches.

The dispenser container package, which utilizes a combination of the dispenser container with its particular configuration of dispensing slot and diagonally folded towels, provides a useful and convenient unit from which towels maybe readily dispensed merely by grasping a pull tab portion .19 accessible, through the enlarged diamond shapedopening 14.

Fig. 7 illustrates a dispenser container package 30 comprising .a rectangular box or carton 31 suitably made from paperboard .and provided with a tear out portion 32, indicated by dotted lines 33, which is removable to open an elongated strip with a centrally disposed diamond shaped opening through which folded products, such as towels or facial tissues can be dispensed. Such a package can be employed to market products for direct use and need not necessarily be employed in conjunction with separate dispenser containers.

Other uses of the invention will be apparent, such as for paper napkins dispensed from horizontally facing slots, and the like.
