(Cl. zas-asa) This invention relates to adevice for starting the dis-` pensing of sheet materialthat `is about to be payed out.

from a dispensing container.. ItV is .t particularly usefulfor transmitting finger thrust to,dispensable sheet material having a slippery surface -suclras aluminum foil,

An object of the inyentionis toavoid the neelfor manipulating a `dispensing box in a Way that must distort or make gaps `openingvinto` the box for gainingL access to the contained foil or other dispensable sheet material in order to regain finger, tip, grasp of a margin of thefoil` :for pulling `a Subsequent length of foil out of the box after adispensed sheet of the f oil has previously been pulled out and torn off ilush with the outer surface of the box.

Another object is to preserve cleanliness and sanitation of the contents of the dispensing box byeliminating unshielding apertures in or between the box walls which A still further object is to utilize in the structure ofsuch device a sheet ofresilientmembranous material having a frictional non adherent surface or surfacing ofrmechanically tenacious nature which while imperforate,

tough and durable nevertheless is so thin and flexible as to be freely capable of bulging, wrinkling and stretching so as to permit substantial movement of the foil impelling frictional surface of the device in a plurality of directions when caused by finger thrust and then operate automatically to restore the frictional surface of the device to` normal starting position after displacement by such finger thrust.

The foregoing and other objects of the invention will appear in greater detail from the following description of `a successful embodiment of the improvements having reference to the appended drawings wherein:

Fig. l is a perspective view of a dispensable sheet of material that has been pulled out from a dispensing box incorporating the invention and partially torn off ush with the outer surface of the box.

Fig. 2 shows a margin of the foil that remained in the box partially ejected by finger application of the dispensing starter of these improvements.

Fig. 3 shows the projected margin ofthe foil grasped by the finger tips preparatory to withdrawing from the box any selective length of foil which can then be torn oif as shown in Fig. l.

Fig. 6 is a detail view of the aperture closing membrane showing its wrinkling `and stretching action when `manipulated ,as in Fig. 2.

Figs. 7, 8 and 9 are views corresponding respectively with Figs. 4, 5 and 6 showing a modification of the aperture closing membrane.

Fig. 10 is a fragmentary viewsimilar to Fig. 7 with parts differently broken away to show a slippery surfacing of the tuck flap of the box cover.

The dispensing container chosen to illustrate the present invention is a conventional elongate folded cardboard box 12 of suiiicient `cross-sectional size to `house a continuous rolled length of aluminum foil 9 wound on and to be payed o from a core tube 10. Aluminum foil serves many domestic purposes such as the protection of ovens from foods that boil over, the covering of bowls that contain foodf in refrigerating storage, the lining of broiler pans, casseroles, etc., the direct wrapping of food such as turkeys or chickens to reduce oven shrinkage, and for covering leafy vegetables or cut fruit to keep them garden fresh in the refrigerator. Foil so used comes into intimate contact with the foods concerned .and needs be kept sanitarily clean and free from soiling or dust collection. The metallic surfaceof such foil is slippery to" the touch, particularly when only one face of the foil is accessible to 'be reached byfthe users fingers when no margin of the foil projects from theA dispensing box.

Dispensing box 12 as shown in the drawings has a folding pasteboard cover 13 terminating in a downward directed ilap 14 that tucks -in between the outer front wall 15 of the box and the front edges of the inward bent top flanges 20 of the box ends 21 when the cover 13 is folded into closed position. ln being withdrawn from the box the foil slides between box wall 15 Aand tuck flap 141 For convenience in tearing off the foil without the use of a separate tool'such as shears or a knife, the fee top margin of the front box Wall 15 is equipped with nesawlike teeth 16 which may be formed in the edge of a thin metal strip 17- fastened broadside against the inner surface of the top margin of box wall 15.

A dispensing box as above described has now become conventional but entails bothersome maneuvering by the finger tips in order to regain access to foil that remains inaccessiblyconned within the box after a dispensed length of the foil has been torn olf `flush with the box by ripping it against the toothed edge 16 of the strip 17 as shown in Fig. l. The present improvement'makes instantly accessible, just prior to withdrawing an additional length of foil from the box, the projecting margin of `a new runof the foil. Such margin by 'means of the present invention becomes accessible for finger gra'sp outside the box as shown in Figs. 2 and 3.

The improved device for accomplishing this is located at an aperture 18 in the front wall 15 of box 12. Com-n .pletely covering all of this aperture there is an elastic membrane 19 of thin, tough and ilexible material capable of considerable bulging, wrinkling and stretching, simultaneously without ruptu'ring. Membrane'19 may or need not be secured all around the border of the aperture in a manner completely to seal the interior of the box, but will be such as to exclude dust, dirt and foreign substances from entrance to the box.

Membrane 19 may comprise a small panel of ordinary deposited latex or Par rubber as thin las A001" to .004 having the usual stretchable and resilient properties that characterize surgeons gloves which properties render the membrane highly llexible, resilient and tough with a nonslippery or minutely creviced surface texture of frictional clinging nature. If desired it may be transparent or translucent. Normally` the panel 19 is held taut across Patented Sept. i6, 193i) the aperture Without slack by securing a major extent of 1ts combined margins in overlapping relation to the mner surface of box Wall 15, as with the aid of an adhesive cut-out 22 that frames the membrane 19, or bare margins of the panel may be bonded directly to the box Wall as in Figs. 7,` 8 and 9. A suitable approximate size for aperture 18 is 5/s x 1%, it being foundV that an aperture a little longer than it is wide best accommodates application of finger or thumb thereagainst and facilitates the desired performance of the membrane.

In Figs. 1 to 6, inclusive, for impellinglyrengaging the front slippery surface of foil 9, a patch 23 having a friction affording surface of gritty nature such as fine sandpaper is fixedly attached to the inner `surface of membrane 19, while on its outer surface membrane 19V xedly carries a nubbin 24 which may also possess a rough or gn'tty surface and need not project outward from the membrane any farther than to be flush with the front surface of box Wall 15. Preferably there is applied a colored marking 25 `around apertureIS on the outside surface of the box to make the location of the aperture more conspicuous.

In the understanding that the roll of foil 9 inside of box 12 is loose and free to turn on its own axis, a dispensing container embodying the improvement when constructed as above described will be used as follows. A previously withdrawn length of foil 9 can be torn off flush with the box by ripping it against the fine toothed severing edge 16 -as shown in Fig. 1. This leaves no accessible portion of the remaining foil projecting outside the box. Now While the left hand of the user holds the box as shown in Fig. 2, the thumb or a finger of the right hand can be applied to the nubbin 24 in a manner to press the friction patch 23 inward and upward against the front face of the foil as is permitted by the elasticity of membrane 19 which makes the membrane capable of bulging inward of the box and wrinkling contractively crosswise in its portions above the nubbin at W while stretching expansively in vertical and lateral directions below the nubbin at S as shown in Fig. 6.

The frictional grab of patch 23 against the front sur* face of foil 9 while the latter is supportingly backed up by the stiffness of flap 14 has been found to seize the face of the foil with sufficient impelling force to eject a narrow margin of the foil to the exterior of the box where it becomes accessible to be grasped by the thumb and fingers of the users hand as shown in Fig. 3. This enables as much more length of the foil to be withdrawn from the box as is desired which length can then be torn off for use as shown in Fig. 1.

In Figs. 3 and 5, it also is shown that the patch 23 and nubbin 24 have been returned automatically to their original location near the bottom of aperture 13 by the resilience in membrane 19 `and are ready for the de-V scribed operations to be repeated.

If it is found desirable to increase the stiffness of the tuck flap 14 for stronger support of the foil against inward pressure by patch 23 the tuck flap may be reinforced by one or more laminations of cardboard or stiffer material as indicated yat 26 in Fig. 5. If the principles of this invention are to ybe incorporated for help in dispensing a sheet material that has a strong clinging amnity for the front surface of tuck flap 14, I prefer to surface the front face of the fiap as shown in Fig. with a slippery coating or covering 30 such as holland cloth or a superpolyamide paper sheet or to dust it with a permanent surface lubricant such Vas stearate of zinc or powdered soap stone at least in the area where the membrane 19 or 19' presses the sheet 9'backward thereagainst while being dispensed. For instance in Figs. 7, 8 and 9, the projecting patch 23 and nubbin 24 are both omitted, or either alone might be omitted, when the nature of the surface of the sheet material 9 to be dispensed and the nature of the sheet impelling surface of the membrane 19 are such as to produce su'icient frictional drag unaided therebetween and by mere pressure'of the operAIA ators finger to impel the sheet material to its position shown in broken lines in Figs. 7 and 8 as by pushing backward and at the same time lifting upward on the bare membrane as shown in Fig. 9.

Nonsticky and nonadhesive Vtextures of surfaces o f membrane 19 that will produce sufficient rubbing fric# tional cling against the face of aluminum foil, without? resort to any patch or nubbin such as 23 or 24 projecting Y from the surface of the membrane, including not only that of natural coagulated Par `rubber but also such for instance as the minutely pitted or microscopically crinkled surface textures produced by molding or fretting operations employed in vulcanized rubber manufacture in ways well known to glove making and allied arts. Also the spongy and easily distortable nature of minutely intersticed surfaces of certain porous plastics, which results from the laying open of tiny fractured surface cells,.can also possess a suiiicientlyhigh degree of non-adhesive impelling cling against the face of aluminum foil but this type of surface texture is more subject to a wearing down to an undesirable smoothness in use, especially whereV there are tiny facial pockets or crevices that may become clogged with foreign substance.

In Figs. 7 and 9 it further is to be noticed that membrane 19 is adhered to the front Wall of the box along only its top and side margins, its bottom margin being left free to move relatively to the box wall. The bond ing adhesive is indicated at 27 in Fig. 7. The membrane could be adhered to the outer instead of the inner surface of the front wall 15 of the box.

This application is a continuation-in-part of my copending application, Serial No. 741,581 filed June 12, 1958, now forfeited.
