l il' [ITTRNEK United States Patent O 3,227,340 SHEET DISPENSING PACKAGE WITH RIGID FENDED TEAR EDGE Theodore G. Haley, 1185 Linden Ave., Stratford, Conn. Filed Jan. 14, 1965, Ser. No. 426,707 19 Claims. (Cl. 22S- 19) This application is a continuation-in-part of my copending application, Serial No. 244,976, filed December 17, 1962.

This invention relates to improvements in container boxes for dispensing and tearing off sheet material from a box contained roll of the material while the box is held in the hand of the user. Such boxes are usually equipped with a sharp tear edge crosswise of which the sheet material is withdrawn from the box and against which the withdrawn sheet is then ripped to sever it.

Boxes for this purpose are usually small enough in girth to be encompassed by the hand of the user and are relatively long to accommodate the length of the contained roll of the sheet material. When made of cardboard, bent in fold-about manner, the girth of the box can be made of a single blank of the cardboard stock bent along parallel lines to form, aside from end walls of the box, a base panel, arear panel, a swingable lid and a fixed front wall of the box, said front wall having a free edge that is substantially met by the swingable lid completely to encom-` pass the box space. In such boxes the lid usually is extended to form a iiap which, as the box is delivered to the user, is bent to extend downward outside of the front wall of the box. When put into use, however, the flap is shifted and tucked inside the box just at the 'back of the front wall.

In boxes of this nature it has been proposed to mount on some part of the front wall of the box a metallic strip having a sheet severing tear edge usually at or near the dis-` charge outlet from the box through which the sheet material is withdrawn.

Problems confronting the users of such boxes have included the necessity for careful handling to avoid accidental cutting of the hands of the user .on the sharp and usually saw-toothed tearoff edge which has heretofore been exposed. Also it has been a problem to exclude dust and foreign matter from entering the box because the front wall of the box heretofore has been sufficiently limber to gap forward and away from the lid and its tuck flap. In boxes where the tear edge has been located other than at the discharge outlet of the box a residual margin of the sheet material has objectionally been left dangling outside the box after the tearing off of that portion of the sheet intended to be used.

An object of the present improvements is to solve all the type mentioned that the same box will dispense, with superior ease and equal efficiency, various kinds of sheet materials now commonly sold in dispensing boxes for specialized uses, for example, polyethylene sheet, slippery surfaced aluminum foil, relatively thick, springy, so called freezer paper, wax paper, and especially the super-thin, clingy, so called Saran wrap. t

The widely different physical properties of these sheet materials as to thickness, tensile strength, resilience, ilexibility, slipperiness, tendency to cling etc. has made it impossible heretofore for a single kind of box construction to dispense and sever the sheet with equal ease and success.

The present solution to these problems resides in im- 3,227,340 Patented Jan. 4, 1966 ICC proved principles of box construction, various embodiments of which are described as follows with reference to the accompanying drawings wherein:

FIG. 18 is a perspective view of a whole box of which FIG. 8 is a fragmentary cross section, the box lid being raised to expose the shelf construction which newly firms the support of the tear strip. f

FIGS. 19, 2O and 21` show three stages respectively in the handling of the box of FIG. 18 for withdrawing and tearing off a length of sheet from the contained roll.

FIG. 22 shows the doubled forward portion of the shelf wall of FIG. 4 extending sufficiently far forward to enable its front edge to overhang the front surface of the front wall of the box and thereat be notched to fortntear teeth, the lifter fingers being cut out from such doubled forward portion of the shelf wall so as to spring up@ ward.

FIGS. 23 and 24 are views similar to FIGS. 10a and 13, respectively, showing the tear teeth produced from the cardboard of the box as in FIG. 22.

FIG. 25 shows a modification of the construction in -3 FIG. 16 wherein the bend of the continuous run of cardboard that forms both the shelf wall and the front Wall of the box is such that a forwardly projecting fin results from a narrow doubling over of the cardboard at such bend and such fin is notched to form the tear teeth.

FIG. 26 shows the notched fin of FIG. 25 directed upward at a slant as well as forward from the front Wall of the box.

FIG. 34 is a fragmentary view taken in section on the plane 34-34 in FIG. 33 drawn on the scale of FIG. 32.

While the present improvements can be incorporated in boxes having a variety of constructions and made of various materials I prefer to follow the well-known custom of forming the box from a fiat sheet of suitably stiff cardboard stock scored and bent in fold-about fashion along parallel lines running lengthwise of the box so as to form a swingable lid 13, a fixed rear panel 14, a fixed base panel 15, a fixed front wall 16, and according to these novel improvements, a shelf wall 17 additional to the said lid and panels and wall. The two said walls preferably have fiat or planar external surfaces that are perpendicularly related so that these two walls stiffen each other on the structural principle of an angle iron. Closure tabs 18 may be provided by endwise continuations of the box panels and walls bent to mutually overlap and interlock in a variety of wellknown ways (not shown) in a manner to permanently and fully close the ends of the box and firmly maintain the desired angular relationship of the aforesaid panels and walls.

The present invention is more particularly concerned with the front wall and shelf wall, each of which stiffens the other at the bend of the cardboard, and utilizes a novel relationship of such bend to other bends of the box walls and to a tear edge with which the box is provided. It has been customary to provide dispensing boxes with a tear strip having a tear edge, usually of metal or other relatively hard surfaced substance, inA a location on the box that offers but flimsy, support, such as at the free edge of the front wall of the box, or in a location requiring a residual length of the dispensed sheet material to be left dangling outside the box after the used portion is torn off at the tear edge.

As an example it has been proposed to equip a dispensing box with a tear strip located at the bend of the cardboard that forms the junction of the above said fixed bottom panel and the above said fixed front wall of the box. With such arrangement it has been proposed to withdraw the sheet from the box at the rim or free edge of the front wall. Therefore, a residual length of the dispensed sheet equal to the entire width of the front wall must always be left dangling outside the box after the sheet to be used has been torn off. Such residual length becomes subject to crumpling and soiling or even contamination in the course of handling and storing the box. This is objectionable because the dispensed sheet material cornes in contact with food to be wrapped therewithin.

My improved construction provides needed firmness and stiffness of support for a hardsurfaced fin such as 24, 36, 58, 65, 65a or 65h having a sharp exposed tear edge such as 25, 41, 58 or 64 which may comprise sawtooth-shaped teeth against which to rip the sheet being dispensed. Such fin may be carried by the front wall of the box as in FIGS. 1-7, 9, 26 and 29-34 or by a shelf wall as in FIG. 8, 15, 22 or 23 hereinafter more fully described. In either case the sharp tear edge projects outward from the box beyond the external surface of the other of said walls yet must enable the sheet material 26 to be pulled from left to right from the box contained roll 27 preferably without menace to the hands of the user.

The present improvements do away with the necessity of leaving exposed to harmful contact by the hand of the user the aforesaid tear-edge. This is accomplished by hinging the swingable lid 13 to the rear panel 14 on its line of junction therewith and making the lid to extend therefrom to such distance that its terminal margin will oscillate, with the swinging of the lid, to and from a position sufficiently close to the tear edge of the fin to deflect the flesh of a users hand from harmful contact therewith. This protects the hand of the user from being cut when the fingers of the hand grasp the box for withdrawing the sheet and ripping it against the tear edge.

In all figures of the drawings the protective terminal margin of the swingable lid of the box falls close to the tear edge. In FIGS. 1 to 28 it is shown to extend forward sufficiently far to overhang the tear edge, while in FIGS. 29 to 34 it serves a similar purpose of protection by nesting directly in back of and close to the tear edge with a thickness substantially equalling or greater than the extent of projection of the tear edge beyond the shelf wall of the box.

The sheet that is being dispensed can be protected from scraping against the tear teeth as the sheet leaves the box by providing the shelf wall 17 with a protuberance 34 which may comprise an embossment of the cardboard of which the shelf is made projecting toward the lid 13. If used with a dispensed sheet of clingy nature the bump or protuberance 34 may be given a slippery surface in any well-known way, as by coating with Teflon. A protuberance such as 34 should terminate somewhat to the rear of the tear teeth 25. After a length of the sheet has thus been withdrawn the sheet is severed by ripping it against the points of teeth 2S.

In FIGS. 1 and 2 the shelf wall 17 has a reverse bend at a distance from the front wall 16 so as to form an extension 28 directed toward the latter and bearing frictionally against the surface of roll 27 with a tendency to spring downward and toward the rear of the box. FIG. 4 it is shown that the shelf wall 17 can be provided with downward bent flanges 29 one edge of which abuts against the inside surface of front wall 16 to act as a bracing stop that helps maintain perpendicular relationship of the shelf wall 17 to the front wall. This resists downward flexing of shelf wall 17 by finger pressure applied inward of the box against the sheet to be dispensed when reached through the opening 30 in lid 13 for urging the residual sheet forward after a preceding length of it has been torn off. The bend of the shelf wall which produces the extension 28 also provides a smoothly rounded linear abutment over which the sheet is slightly flexed on its way from the roll to the outlet of the box. In boxes where the flanges 29 are omitted, as in FIGS. 5 to 7, the shelf 17 may have quarter rounded ends as indicated at 19 in FIGS. 2 and 18. This tends to avoid snubbing of the edges of the sheet against the end of the box opening and such avoidance can be promoted by giving the whole length of the inner edge of the shelf a convex arcuate curvature.

FIG. 5 shows a modied extension 28 of the shelf wall 17 in which the former is doubled back to fully underlap the latter and reaches into tight edgewise abutment against the front wall 16 whereby to act as a support resisting `downward flexure of the shelf `wall beyond its perpendicular relation to the front wall.

FIG. 6 shows a further modied shelf extension 28a in which the length of such extension is prolonged downward to reach into edgewise abutment against the base panel of the box and lie in face-to-face contact with the inner surface of the front wall 16 of the box.

FIG. 7 shows a still dilferently modied form of the shelf extension 28h in which the extension reaches straight down into contact with the base panel 15 and is bent forward at its bottom to form the ange 32 whose edge abuts against the front wall 16 forming a hollow chamber 31 between the extension 28b and the front wall 16. Instead the flange 32' may be turned rearward as indicated by broken lines in FIG. 7 and glued to the base panel 15 of the box. I

In FIG. 8 the tear strip 36 is mounted on the shelf wall 17 instead of on the front wall 16 and projects slightly beyond the plane of the outside surface of said front wall so that the sheet being dispensed can be severed by ripping it downward against the teeth of the tear strip 36.

FIGS. 9 to 15, inclusive, show a modied form of tear strip illustrated in enlarged detail in FIGS. 14 and 15 and also show 'a modified means for maintaining the sheet 26 lifted above the level of the tear teeth 41 of strip 40. Tear strip 40 is made by folding on its longitudinal center liner a thin metallic strip so that its free edges can straddle and clinch ns 42 produced by the bend in the cardboard stock wherethe front box wall 16 meets the shelf wall 17a. To produce the cardboard fins 42 the cardboard blank is pierced with holes at 43 and slit at 44 between alternate pairs of holes 43 and scored at 45 between the other pairs of holes, instead of merely being scored continuously along the line of bend. When the bend takes place along the intermittent scores 45 in FIG. 11 the fins 42 upstand above the surface of the shelf wall as shown in FIG. 12 and are ready to have clinched thereto the tear strip 40 of FIGS. 14 and 15 as best shown in FIG. 15.

The aforementioned modied means for maintaining the dispensed sheet normally elevated above the tear teeth 41, to avoid scraping the sheet against the teeth, is shown in FIGS. 9 and 10, and may be a hinged tab 48. A narrow margin 49 of tab 48 is fixedly and permanently secured to the top surface of the shelf 17a so that the remainder of the width of the tab acts as a lip 5t) depressibly inclined upward away from the shelf wall. Resilience in the substance ofthe lifter tab 48 at the hinge where the mounted margin 49 of the tab joins the lip portion 50 of the tab is sufficient to uphold the weight of the dispensed sheet 26. Also it offers sufficient resistance to the downward pressure of the users thumb in the opening 30 to afford a frictional grab of the users thumb against the surface of the sheet to be dispensed whereby to urge it outward to its position in FIG. 9 where it can be grasped for further withdrawal from the box between the thumb and a finger of the users hand as shown in FIGS. 20` and 21. In FIGS. 10a, 11 and 12 there are two spaced apart, up sprung lips 50 formed by doubling over against-its own `top surface the cardboard stock ofthe shelf wall in its rear marginal portion 51. The space 53 between the sheet lifter lips 50 affords more ready access for the forenger of the users hand to the under surface of the sheet being dispensed as the thumb presses downward and draws forward upon the sheet.

In my improved box construction the lid 13 may initially have at its free end a flap 52 bent down over the front wall 16 and removably attached in overlapping relation thereto as by spot gluing. This makes a sealed closure for the box as shown in FIG. 1 until it comes to the hands of the user. The bend atwthe junction of liap` 52 and lid 13 is pierced 6r line perforated so that the former can easily be torn off from the latter at said bend when the box is put into use. When this has been done the box is conditioned as shown in FIG. 2 where it also is seen that the pierced outline of an opening 30 in lid 13 has resulted in tearing out of the lid a portion thereof that leaves such opening.

Whereas FIG. 18 shows the lid 13 lifted to expose the shelf 17 and equipped with end wings S4 that tuck into the box, such lid will normally remain locked down in its position shown in FIGS. 19, 20 and 21 by any suitable binding engagement of wings 18 with the end walls 18 of the box. Pressure of the thumb downward on the lid 13 in FIG. 21 will increase the frictional drag of the lid against the portion of the sheet 26 that occupies the space between the lid and the shelf Wall 17 before a payed out length of the sheet has been torn off. This resists further payout of sheet while tearing.

FIGS. 19, 20 and 21 illustrate the use of the box. In FIG. 19 the only portion of the sheet accessible for contact by the users hand is the small area exposed in the opening 30. The users thumb is pressed against the sheet in this opening with a forward rubbing movement which withdraws a suflicient marginal extent of the sheet from the box opening to be grasped between the thumb and foreiinger lof the hand as shown in FIG. 20, after which any desired length of the sheet can be pulled from the box as shown in FIG. 21 and torn off by iiexing it downward against the tear edge of strip 36 which may or may not be toothed.

I have discovered that the cardboard from which the shelf wall and front wall of the box is made can by suitable treatment be serrated to form adequate tear teeth that will satisfactorily take the place of tear teeth such as 25 or 41 formed on a metallic strip attached to the cardboard. Such cardboard teeth can be hardened to a point where they are durable in service and capable of cleanly severing even aluminum foil and heavy weight, so called freezer paper by the application of a suitable hardening agent preferably of such consistency that the cardboard ,to some extent can absorb the treating agent before hardening takes place. For this purpose I have found it satisfactory to coat the cardboard serrations with a onestage alkaline reacted straight phenolic resin of syrupy consistency, reacted to a point where it will set by air drying but capable of faster setting by the application of heat, say at about three hundred degrees Fahrenheit for 10 seconds, more or less.

FIGS. 22, 23 and 24 show that a cardboard edge so serrated and treated to form the tear teeth 58 can be afforded by doubling the shelf wall 17e forward upon itself to form the overlapping portion 59 which extends `suihciently far forward to cause its front edge to overhang the front wall 16 of the box whereat said edge is serrated to form the tear teeth 58. Preferably the shelf wall 17c and its doubled over portion 59 will be securely glued together in face-to-face contact. Stippling 60 represents the marginal region of the cardboard where the aforesaid hardening treatment is applied.

FIGS. 22, 23 and 24 further show that resilient, sheet lifting lips 50a can be struck up from the cardboard of the doubled over portion 59 of shelf wall 17e for performing the same function as lips 50 in FIGS. 10a and 13. FIG. 28 shows a different way of producing moditied uplift lips 50h from the cardboard of the shelf portion 59 that will have a strong uplifting force and preserve without interruption the full strength of the entire bight of cardboard constituting the rear edge of the shelf wall 17C.

Still another way of utilizing the cardboard of the box to constitute the tear teeth 64 is shown in FIGS. 25, 26 and 27. In this construction the bend in the cardboard that joins the shelf wall 17d to the front wall 16 of the box is such as to pinch together said walls at said bend and form the iin 65 in FIG. 25 or the fin 65a in FIG, 26

7 or the n 65h in FIG. 27. Such fin thus is composed of a bight of the cardboard that makes the fin consist of two plies of continuous cardboard that are glued firmly together throughout their areas of mutual surface contact. The tear teeth 64 can then be notched in the bight of the fin to any suitable depth.

The fin of two-ply cardboard thus formed can be oriented so as to project straight forward in over hanging relation to the front wall 16 of the box as shown in FIG. 25, or so as to project diagonally upward and forward from the bend thus to stand out from the planes of both the front wall 16 and shelf wall 17d as shown in FIG. 27. In the constructions of FIGS. 25, 26 and 27 the same hardening may be used also as the adhesive that bonds together the two plies of cardboard of the fin.

As a modified construction for fending the sharp tear edge 25, which need not in all cases be serrated to form teeth, FIGS. 29-32 show the box lid 13a provided with a two-ply, doubled-under terminal margin 70 that moves with swinging of the lid to a position wherein it is nested in a space just at the rear of and close against the tear edge 25 of fin 24, thus padding said space while fianking that part of the tear edge which projects above the shelf wall 17b and with sufficient closeness to defiect the flesh of a users hand and prevent injurious contact of said tear edge therewith. FIG. 32 indicates in broken lines a slightly lifted position to which terminal margin 70 of the lid can yield to permit withdrawal of the dispensed sheet 26 in a somewhat upward direction to clear the tear edge 25. When the desired length of sheet is withdrawn, progressive pulling downward on the withdrawn sheet will cause it to be ripped or severed against the tear edge.

FIGS. 29-32 also show in full and broken lines alternate paths for the sheet when being drawn from the top or the bottom of a nearly ful lor nearly depleted roll on the core tube 27. Thus in FIGS. 29-32 the sheet can be withdrawn from a roll placed in the box to be rotated either clockwise or counterclockwise by the pulling off of the sheet. FIGS. 2932 further show the tongue 69 of cardboard stock that was struck inward from the lid to produce the notch or aperture 30, bent rearward and slanted downward to bear resiliently on the sheet 26 as it is being withdrawn from the roll. This tongue acts as a yieldable brake to prevent overrunning rotation of the roll if the sheet is yanked out of the box abruptly. FIG. 30 illustrates how additional tongues such as 68 can be struck inward from one or more other panels of the box in a choice of locations to help orient the roll to positions in the box from which it will most easily pay off the sheet being dispensed. Also in FIGS. 29-34 the sheet lifting lips 60h lie within and are exposed by the notch or cutout 30 in the lid as in FIG. 23.

In case the folded-under terminal margin 70 of the box, as shown in FIGS. 29-32, fails to possess a desirable degree of longitudinal stiffness, greater stiffness can be imparted to the lid by suitable ribbing, for instance a depending, two-ply doubled-over, fiange-like fold or bight 71, the terminal margin 72 of which can be manually pressed down against the sheet passing over shelf wall 17b or can be left free to incline upwardly as shown in FIGS. 33 and 34 in the region of the shallow notch or cutout 30a. Manually pressing downward on margin 72 with the fingers of one hand while withdrawing the sheet with the other hand imparts selective braking resistance to withdrawal of the sheet.
