SLIDE PACK SHEET DISPENSER Filed Jan. 50, 1962 2-Sheets-Sheet 1 FIG,7 "1

INVENTOR JOH N P. GR EENE ATTORNEY June 1, 1965 J. P. GREENE SLIDE PACK SHEET DISPENSER 2 Sheets-Sheet 2 Filed Jan. 50, 1962 N INVENTOR. JOHN P. GREEN E ATTORNEY United States Patent Corporation, North Newark, Nl, a corporation of New Jersey Filed Jan. 30, 1962, Ser. No. 169,725 12 Claims. (Cl. 206-57) This invention relates to dispensers for sheet material and, more particularly, to one in the form of a slide pack, that is, in which an inner portion slides longitudinally with respect to an outer portion in order to expose sheets or leaves for withdrawal one at a time.

With the development of soap and the like in the form of sheet material, an example being loose leaves to take the place of cakes or liquid, the problem arises as to how to dispense such leaves one at a time to use in a conventional manner and without wastage. The present invention relates to a small package which may be carried in a pocket or purse and be used to expose the top one of a stack of leaves for withdrawal one at a time as desired.

An object of my invention is to provide a'package comprising a cardboard box formed as an outer portion or sleeve, an inner portion or slide longitudinally movable therethrough to a limited extent, said inner portion being formed to expose leaves for withdrawal one by one from a contained stack thereof, the inner portion comprising two bottom walls slidable with respect to one another and connected at the leaf-withdrawing or access end of the package by a double end wall formed by united portions folded upon one another but with their bottom edges spaced so that they are normally disposed at an angle to one another where they unite at the top, means connected to the sides of the upper bottom wall of said inner portion and lying inside of said outer portion,

I and means on the lower bottom wall of said inner portion to initially limit sliding movement of only the lower of said bottom wallsof said inner portion, whereby when said means connected to the upper bottom wall are longitudinally pushed toward the leaf-withdrawing end of the package, the upper part of said inner portion slides along its lower bottom wall and the double end wall is moved down to open position to expose the top leaf of a stack thereof for withdrawal from the package.

Another object of my invention is to provide, in a package as above described, sharp means projecting from the upper bottom wall of said inner portion and on which are impaled portions of leaves contained therein remote from the access end of the stack, to limit withdrawal of said leaves to one at a time.

A still further object of my invention is to provide, in a package as above described, an extension of the lower 'of the bottom walls, remote from the leaf-withdrawal end of the package, as a flap which is bent up to form a swingable end wall and a tab extending from the top of said wall partially covering a stack of leaves when disposed in said package and lying inside said outer portion, said swingable end wall serving as the means which is pushed against to project the inner portion partially out of the outer portion to expose leaves for withdrawal "ice dispenser embodying my invention and shown in closed position.

FIGURE 12 is a fragmentary longitudinal sectional View of the right hand end portion corresponding with FIGURE 3, but showing a modification.

Referring to the drawings in detail, there is shown a slide pack It) to provide a convenient, easy to use, portable package containing from about 30 to 50 leaves or sheets of soap or other material desired to be dispensed. The illustrated embodiment is well adapted for feeding leaves of material entitled Detergent Film Composition, described and claimed in the Robert J. Anderson application, Serial No. 762,938, filed September 24, 1958, now abandoned after being replaced by continuation-impart application, Serial No. 316,514, filed October 16, 1963. The package is easy to open by using one or two hands. It is easy to close using one or two hands, and keeping in mind the fact that the fingers of one hand will be holding the pack and the fingers of the other hand will contain a leaf or two of the soap, if such is being dispensed.

The pack Iii closes completely and remains closed when carried in a pocket, glove compartment, purse or handbag, and substantially resists the entry of foreign material such as dust. The pack is so designed that one leaf is withdrawn at a time in normal operation and the balance will not fall free as a result of careless handling. It is so designed that the last leaf in the pack is as easy to withdraw as the first.

Generally, the slide pack 10 of my invention comprises two parts referred to as the outer portion or sleeve 11 and the inner portion or slide 12. The slide or inner portion 12 is a folded cardboard construction resulting in a double-wall front and base. The sleeve 11 is a portion which is wrapped around the slide and has means cooperating with portions on the bottom of the slide to limit longitudinal movement between the parts.

As will be seen by referring to FIGURE 7, the outer portion or sleeve is made from a desirably cardboard blank 13 comprising a top panel 14, a bottom panel 15, a side panel to connecting the top and bottom panels and side panels 17 and 18 which are adapted to overlap,

other.

.posed at the other end of said package- These flaps respectively cooperate with depending tabs 36 and 37 on the slide12 or inner portion of the package to limit longitudinal movement between the parts. The top panel 14 is desirably notched, as indicated at 22, to facilitate engagement of the inner portion 12 by a thumb or finger to efrect sliding movement between the parts.

The inner member or slide 12 of the package is formed from a desirably cardboard blank 23 which consistsof upper andlower bottom panel portions 24 and 25; The portions 24. and 25, when in assembled conditiomprovide two bottom Walls slidable with respect to one an- These walls are connected at one end, that is, the leaf-dispensing end of the package, by a double end wall 26 formed by a panel 27 hinged to the .part 24and a panel 28 hinged to both the part 25 and the part 27, i

7 There is a panel 29 connected to. one side edge of the panel 24 and apanel 31 connected to the other edge -of said panel.- The panels 29 and 31 are bent to rectangular relationship with respect to the panel 24 and terminate at their upperiedges'in inwardly extending flanges 32 and 33, respectively. The panel at the endopposite the panel 28 is provided with a panel 34 terminating in a vflap .35. The panel 34 forms an end wall, when the parts are assembled, opposite the double end wall 26, the flap 35 being formed to overlie the flanges 32 and 33 and soap leaves 43 or the like c ontained in the package.

Struck downwardly from the panel 25 are tabs 36 and 37, the former cooperating with the end flap 19 of the sleeve 11 and the latter cooperating with the end flap 2]; of said sleeve when assembled therewith, to limit sliding movement of the slide 12 with respect to the sleeve 11. The panel 24 receives a sharp prong 3S slit from a metal plate 39 and projecting upward throughan aperture 41; therein to provide a sharp or needle-like. member on whichend portions of the stack of contained leaves 4*? are impaled to secure them in place for withdrawal one by one from the top of the stacks. The panel 25 desirrably has a slot 42 through which the plate 39 may be viewed, I r i To assemble the partsforming the package, the blank" 23 is bent from the position of FIGURE 9 through that of I FIGURE 10 to that illustrated in FIGURE 6, including the incorporation of the plate 39 with its upstanding sharp prong 3 8. A stack of leaves 43 may then be placed in I the so formed interior of the inner member 12, withtheir rearward end portions impaled on the prong 38, if such a prong is used as is desirable, Theouter portion llis formed by. bending .the blank 13 from the position of- FIGURE 7 through that of FIGURE 8 to that illustrated in EIGURE 5. Said bending is, however, around the formed inner portion 1 2, so that the tabs 36 and 37 are simultaneously disposed between the end flaps 19 and 21 of the router portionl l. Thus movement of the inner portion 12 with respect to the outer portion '11 is limited to that between engagement of the tab 36 with the flap 19 of theisleeve member 11 about the slide member 12 is sure is applied to the inner portion 12 on the .line 44, that is, at the junction or. hinge between the panel 34and the flap 35, and preferably at the center of this line.

' This causes the slide or inner portion 12 to move to- 1 ward the position of FIGURES 2 and 4 where the tab on the lower bottom wall 25 of the slide engages the.

andengagement of the, tab 37 with thefiap 21, Closure end flap 19 on the outer portion 11, Any further force or motion on said pressure point or line causes the upper bottom wall 24 to continue outward relative to the lower bottom wall 25, which is held .by the flap 19. This re-. sults in the double wall 26 of'the slide snapping down from theposition of FIGURE 3 to that of FIGURE 4 and leaves the pack fully open.

The reason for this action is that the top of the panel 34 engages the flanges 32 and 33 and .pushes them and their connected upper bottom wall 24to rotate the panel 728,,about its connection with the wall 25rby downward swinging of the panel 27 about its connectionwith the wall 24-. This action is.:possible because of the initial formation of the right angled triangle attheriaccess end of sure for the pack must be applied at the edge .44., preferably in the center. If pressure isapplied at some point below thisedge, the slide? 12 can the projected out from the sleeve 11 in a satisfactory manner, but the action of the automatic snap-down feature on the slide may not be satisfactory because theinner bottom wall 24 is not then moved out with respect to the, outer bottom wall 25.

"To guard against this possibility, analternative construction'is illustrated in FIGURE 12. This construction showsthe right hand end of the slide to ,be angled, that is, it initially provides an acute'rather than a right angle at the point 44, so that-pressure is applied at the acute angle point. Byvirtueof having this construction of the slide 'or inner portion, an operator is automatically directed to this acute-angledpart thereofzto-press sol-that the desired operation occurs.

it wi l be seen thatan importantfeatureof the package ltlis the double wall constructionof the slide at the access end, initially makinga right angled triangleiformed by extensions of the upper and lower bottom portions thereof. In order for the' front to (snap down it is necessary thatthere be relative motion between the two bottom :Walls of cardboard, such motion being accomplished by pushing with a finger or thumb at the point designated 44 or 4-4. In the'embodiment illustrated, the sleeve or outer portion 11 isrformed to close the. slide or inner portion 12 withia :rathersnug fit. Thisibetter enables the frontior access end of theslide toremain in a semilocked condition when the package is closed, The front of the slide can be forced open-when the package is closed, but this becomes muchxmore difficult if a snug fit is provi ed.

Having now describedmy invention in detail in accordance with the Patent Statutes,-those..skilled inthis art will have no diificulty in making changesand modifications in the individual parts or their relative assembly in order to meet'specifiorequirements or conditions. Such'changes and modifications may be made'without departing from the scope and spirit of the invention, as setforth in the following claims. 7
