nite c 42,889,098 DISPENSING CARTON FOR WRAPIIN G MAT- RIAL IN THE FORM F SHEETS AND FILMS This invention relates generally to the class of receptacles and is directed particularly to improvements in those receptacles or boxes designed for marketing and lalso for dispensing rolled sheet material.

The use of various types of sheet material for wrapping articles, particularly in the home for wrapping foodstuffs or the like for the purpose of preserving the same, is very extensive. Such sheet materials are in the form of aluminum foil, waxed paper or transparent plastic film of a special design which is treated vwith static electricity so that it will readily adhere to itself or to objects about which it is wrapped. Such materials are generally marketed in rolls which are enclosed in boxes or cartons from which the material may be withdrawn in the desired length and means is usually provided upon the box or carton for facilitating the tearing off of the Withdrawn length of the sheet or film.

In the case of the above referred to specially designed plastic lm, it has fbeen the experience of many persons using the same that after a portion of the film has been torn from the roll, the free end will slip back into the box and strongly attach itself to the adjacent surface of the roll, with the result that when another section of the film is desired for use, great difliculty is experienced not only in finding the edge of the material but in grasping it and getting it started from the roll to be withdrawn from the carton.

In View of the foregoing, it is a particular object of the present invention to provide a new and novel box or receptacle which is designed particularly, although not necessarily exclusively, for merchandising rolls of the above referred to special film and more especially for facilitating the easy withdrawal of a portion of the film and its removal for use and for retaining the free end of the roll in a position where it can again be easily grasped when another section is desired for use.

Another object of the invention is to provide a box or receptacle for the above described purpose which is so constructed or designed that the film or sheet of material as it is being withdrawn will run over a smooth edge and ybetween spaced portions of a wall of the receptacle where the free end will be held or retained after the desired withdrawn portion has been detached from the roll. t

Still another object of the invention is to provide an improved box or carton for the purpose stated wherein there is provided a portion of one wall in the form of a panel beneath which the free end of the roll will be retained and which, in the event that such free end of the roll should for any reason slip back into the carton, can be raised to give access to the roll and then be replaced to provide a guide and covering means for the end portion.

A still further object of the invention is to provide a novel form of blank in one piece which is adapted to be folded to form the box or carton and to provide a top portion in two overlapping parts or panels which cooperate to form a guide for the sheet or film material States Patent as it is drawn from the carton and to retain the free end of the material after the sheet has been cut oli.

A still further object of the invention is to provide in a box or receptacle of the character stated, a new and novel type of cutter which functions with greater eiciencythan cutters of the type at present in use, thereby insuring the clean cutting of the sheet without crumpling and which will not become ineffective by reason of clogging by portions of the film or sheet adhering thereto.

The invention will be best understood from a consideration of the following detail description taken in connection with the accompanying drawings forming part of the specification, with the understanding, however, that the invention is not coniined to a strict conformity with the showing of the drawing but may -be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

Fig. 5 is a plan View of the carton blank; and

Fig. 6 is a plan view of the cutter strip per se, with the central portion thereof lbroken away.

Referring now more particularly to the drawings, the numeral 10 generally designates the complete closed box or carton of the present invention. 'Ihis box or carton, except for the hereinafter described cutting strip, is formed from a single blank of material such as cardboard or the like, as shown in Fig. 5 where the blank is generally designated B. The blank as shown in Fig. 5, is of generally rectangular form and for housing a roll of sheet material is, of course, of materially greater length than width, the numerals 12 and 14 designating the longitudinal edges while the overall length of the completed box is designated by the transverse dot and dash lines 16. These lines 16 also represent the fold lines for the end walls and attaching tabs as hereinafter described.

The blank is laid olf longitudinally to define a number of panels each of which in the completed carton will form a wall or a portion of a wall. These panels are designated 18, 20, 22, 24 and 26, being separated by the fold lines 27, 28, 29 and 30.

The panel 20 in the completed box or carton forms the fold wall which, in the other figures, is designated 20' while the panel 22 forms the bottom wall of the carton designated 22 and the panel 24 forms the back wall of the carton designated 24. The panels 18 and 26 overlap and cooperate in the completed carton to form the top wall which is generally designated 31.

The front wall forming panel 20 is provided at each end with a tab 32 the width of which, which in the lblank is directed lengthwise of the panel, is approximately half the width of the hereinafter described end wall of the carton, and the end edges are out along outwardly convergent lines as indicated at 33 and 34 to facilitate folding.

At each end of the bottom Wall forming panel 22 is the end wall panel 35 which, in the completely formed 3 box, forms the end wall 35' as illustrated in Figs. V1, 2 and 4.

The outer edge of each panel 35, by which is meant the edgeof the panel/farthest from the panel 22 from which it extends, is cut across the major portion of the width of the panel to form theoblique or inclined edge 36 Awhich at-its innermost end joins an inner edge :37 of an ear 38.

The'numeral 39 designates an attaching tab at each end of the back wall forming panel 24. These tabs are of the samewidth as the tabs 32'and the side edge of each nearest to a panel 35 extendsobliquely across the width of the tab in divergent relation with the adjacent edge of the panel 35, as indicated at 40. The opposite side'edge of each panel 39 from theedge 40 is notched Vas at 41to match the form of the outer edge of the adjacent Vend wall panel 35 when thelbox is folded.

Each end of the panel 18 has extending therefrom orf joined thereto a narrow securing tongue 42.

The panel 26 which forms a part of the top wall 31'in association with the panel 18 is folded lengthwise along the line 43 which fold line is relatively close to the fold line 30 so' that the 'panel is divided Vinto two parts a and b.

In folding the blank B to form the box or carton the panels 2l) and 24 are folded up along the lines 28 and 29 so as to be disposed vertically at right angles to the panel 22, thus formingthe hereinbefore Vreferred to front and back walls 20 and 24 respectively and the outlying panels 1S and 26 are likewise folded along the fold lines 27 and 30. In folding these panels V18 and 26 they would be folded inwardly toward the inner faces'of the adjacent panels 20 and 24, respectively, but the panel 26, when `folded along the line 43, `wouldibe bent sothat the part b would be turned back against the outer face of the smaller part a. The end wall panels 35, the tabs 32 and 39 and the tongues 42 are all bent or yfolded inwardly along the lines 16.

Tabs 32 and 39 at the two ends of the panel are glued to the inner faces of the adjacent end wall panels 35. Fig. 2 illustrates the manner in which the front and Vback walls at one end of the carton are placed in position against the inner surface of the adjacent panel 35 which when bent up forms the end wall l35'. After the tabs are secured in the manner stated to the end wall panels the roll of sheet material is placed within the carton and the panel 18 is then folded in until it rests at its ends upon the inclined edges 36 of the end wall forming panels. In making this fold the tongues 42 are positioned against and glued to the outer faces of the adjacent end wall panels.

It will Ibe seen upon reference to the blank in Fig. 5 that the edge 33 of each tab 32 is soangled that when the tab is glued into position such edge will lie parallel with or slightly below the edge 36 of the adjacent end wall panel. Likewise the notch 41 formed inthe side of each of the tabs 39 will conform to the inclined edge of the adjacent end wall panel 35 and the ear portion 38, as is clearly shown in Figs. land 4.

The narrow strip portion a of panel 26 is folded down to extend at a downward and forward inclination between the ear portions 38 of the end walls vand the conforming portions of the tabs 39 at the inner sides of the end walls and the wider part b of thepanel 26 which may be defined as the ap, is brought down against the surface of the panel 18.

The numeral 44 generally designates a cutter which is secured along the outer face of the ifront wall 20 at lthe bottom edge thereof. VThis cutter comprises Aa strip of metal 45 or any other suitablematerial, which along one edge is formed to provide a row ofv cutting teeth 46. These teeth 46 are all relatively :sharp'pointed as shown, and are disposed to project outwardly from the body ofthe strip atan oblique angle to the -length 4 t thereof and as shown in Fig. 6, the teeth are all pointed in the same direction. The teeth are set so that when the strip is secured to the wall 20 -by rivets 47 or in any other desired manner, they will point away from the person using the box or carton when holding the latter in the left hand with the wall 20 directed to the right. Since the majority of persons are right handed, the cutter is set to have the teeth pointing away from the user when the carton is held as described so that when the film or strip of material is drawn out as shown in Fig. 4 where the drawn-out'part to be torn olf is designated 48, and the :free edge-of the drawn-out portion is grasped with the right hand, it can be pulled down against the pointed teeth 46 andeasily cut from the roll. The roll in Fig. 3 is generally designated 49 and in this ligure the edge portion of the material is shown in between the part b of the panel 26 and the panel portion 18.

In tearing away a section ofthe roll of tlrn in the manner shown in Fig. 4, it will be seen that a substantial portion of the lilni will be left and will remain outside of the carton, extending from the carton between the overlapping panels`18 and 26 which form the top wall '31 and thus the edge of the material may beeasily grasped when it is next desired to withdraw a portion of the roll of material for use.

If for any reason the end of the material should get back into the box, the user may open the box by pulling up on thepanel 26 and thus obtain access to the roll through the open area designated c in Fig. 3 'which is provided between the longitudinal edge of the panel 18 and the back wall 24. vIf the roll end cannot be reached in this manner, then the end tongues 42 may be detached so that the panel 18 can be swung to open position alsoand the roll may be removed from the box. When the roll is replaced, the panels 18 and 26 will be returned to the positions shown in Figs. 1, 3 and 4 and althoughthe end tongues 42 and the panel 18 will not be secured, the pressure of the thumb of one hand against the panel 26 will keep the panel 18 from slipping Vout of position.

The panel 26 will also be retained in its operative position by reason of the fact that the portion a thereof lies between the upstanding ears 38 of the end wall panels and the adjacent portions of the tabs 39 which are secured against the inner faces of theend wall panels, suchre- Ytention of the portion a being effected by its rictional engagement with the inner faces of the ends of the carton which the end wall panels and the tabs 39 provide.

The combination of the end Wall panels 35 andthe tabs 33 and 39 provide end structures for the carton' of double thickness which will rigidify the carton so that it cannot become distorted in use.

From the foregoing, it will be apparent that Vthere is provided by the present invention a new and novel box or carton structure particularly well adapted for merchandising rolls of material of the character described and especially well adapted for dispensing roll material of the particularly'described plastic type which heretofore has presented certain difficulties in connection with its use in other types of cartons.

It will also be apparent that there is provided a type of cutter for attachment to a carton of the character stated vwhich will more efliciently cut the withdrawn material by -reason of the manner in which the teeth are formed and disposed along the edge of the carton.
