' 1 Tinnitus. 1(CLZ2'SS-48) This invention. relates to an improvement in dispensing carton and deals particularly with a carton useful in adjoining-front wall of the carton,- and "the front: wall is usually provided with a metal tcutting edge by means of which'th e sheet'maybe conveniently torn. While-openings-have sometimes been provided-in the top panelto permit (the upwardly projectingedge of the sheet material tobe grasped, it is difiicult to .grasp -,-a sheet and topu ll it outwardly and under normaloperation the-cover of the package :isopnedeach time theisheet is to bedis pensed so that the sheet may the-readily grasped-and withdrawn.-- This arrangementnecessitates-the extra operation of opening and then .closing' the -coverwhich istime consuming and bothersomeu V a Anobject-of the present invention resides in the provisionof a dispensing carton having an openingthrough which the sheet maybe dispensed which is located at a point Jspaced from the metal cutting edge. The end' of the sheet iscwithdrawn withing'the opening and-drawn over a-portion-of the exterior surface of the carton; The sheet is-then out along the cutting edgeso that a portion of. the, extremity .ofthe sheet remains overlying theex. ter-ior of the carton; As a result, the next time sheet material is desired, the edge; of the sheet isreadily avail able and maybe grasped to withdraw additional'sheet material from the carton.

A feature of the present inv'entionmesides in a novel and efiectiverneans of resisting the rotation of the sheet material and its supporting score during transportation, andhandlingn. This-means for resisting rotation also provides a tension in the-sheetat -all times so that the rc-: moval of the'material may be more efiectively. controlled.

In'l addition, this meansresisting the rotation of-the roll of sheet material in thecartonacts to hold the marginal edge of the sheet in a set position prior to the time the carton .is handled. Accordingly, .when the carton is the' provision of a means for preventing the unwinding Patented-1 for'preventing'themarginal zedge 'of 'therSheetIfromLun rolling, thereby keeping the marginaledge insa prede termined po'sition'until the carton is opened;

A-fuitherfeature of the present. invention. lies in me 'fact thatathen'oll may, if 'desiredybe provided withc'a leader or a pull-strip which is relatively narrow aas' compared to the sheet;being dispensed and which is attached between ith'e fmarginaledgeiof the sheet "and zthe next 'adjoiningzconvolution. of the sheet material. This leader may be arranged so that its end will be located adjoining the opening in the 62111011312 the timethe carton is-opened.

v By'pulling on this leader, themarginal edge ofthe-sheet may 'bezpulled' away :from the rest of the roll andathrough the carton opening -so1that the sheet material may be dispensed;

These and other :objects' and novel-features :of the :present'invention will: be more: clearly and fully -set forth in the following specification and claims.

Fi gure 12 is a cross:sectional view'through 'thecarton of Figure 1.1 after the same has been opened. The car'ton is indicated: in the drawings by thelett'e'r Ai' The' carton normally appears as indicated in -Figures="l and 2 of the drawings and the blank from which-the carton is formed "is best illustrated in Figure 6 of the drawings.

The blank includes a front wall panel 10, a bottom panel 11', a rear wall panel 12, and a top Wall panel1'3 which are connected along

parallel fold lines

14, 15 and 16, respectively. The top panel 13 is foldably 'c'onn'ected' to a glue flap 17 along a line' of'fold 19. w

Carton closing fiap's 20, 21, 22 and 23'are fold'ably connected along an end of the

panels

10, 11, 12 and :13;

of' thejsheet material on its core during transpoiftationi alonga line of told 24; A line of fold '25 connects the otherends' of these

panels

10,11,12 and '13 to closing

flaps

26, 27, 29 and 30; These closing flaps are'de'signed to fold into right angular'relation with the various wall panels described and to form end closures therefor.

Flap 20 is shown "as extending approximately one halt the area of the end of the carton and this flap'ZO is connected to a flap extension33 along a foldline 32. 'Asim ilar fold line 34 connects the flap 22 with a flap extension 35. Flapextensions36 and 37 are-foldably connected to'the

closing flaps

26 and 29 along lines 0f=f0ldi39 and 40. 'The var'iousfiap extensions which have been dc scribed are designed to extend intofthe core of thcTdllf of sheet material 'in a marinerwhich'will be lateif -tl "f V scribed more indetail. y

' A tear strip 41 extends longitudinally of the top panel 13 throughoutits length. Extensions 42 and 43 are provided at the end of the tear strip 41, these extensions being cut from the body of the flaps 23 and 30. These extensions 42'and' 43 remain in the plane of the :top panel of the carton and provide slight projections by means of which an end of the tear strip may be engaged, By pulling the tear strip upwardly, it may be removed from the top wall 13, leaving an elongated passage through the top wall of the carton.

As is indicated in Figure 4 of the drawings, a pair of

cut score lines

44 and 45 extend in parallel relation across the undersurface of the top panel 13 from end to end thereof.

A second pair of

cut score lines

46 and 47 extend into the upper surface of the carton in parallel relation, these cut score lines being spaced apart a distance somewhat wider than the spacing of the

cut score lines

44 and 45 and being slightly outwardly thereof. Accordingly, as the end of the tear strip 41 is grasped and pulled upwardly, the stock forming the paperboard will split intermediate its upper and lower surfaces between the cut score 46 and the adjoining score 44 and also between the

adjoining scores

45 and 47 to produce an opening which is shaped similar to that illustrated in Figure of the drawings.

A metal cutting edge 49 is secured to the upper extremity of the front wall and usually projects slightly above thelevel thereof. This cutting rule 49 may be secured in any way such as by prongs punched inwardly from circular areas 50 to extend through the carton stock and to be clinched over on the inside of the carton. As this structure is not novel, it is not shown in detail.

As is indicated in Figures 3 and 8 of the drawings, the carton A is designed to contain a hollow cylindrical core 51 'onrwhich is wound sheet material 52. As this material is extremely thin, Figures 9 and 10 have been added which are greatly enlarged for the purpose of illustration. Figure 9 of the drawings illustrates the sheet material 52 having a marginal edge 53 which is preferably located immediately below the tear strip 41, although this may be varied. A relatively narrow strip of paper or other suitable material which may be defined as'a leader is indicated at 54 and is provided with a spot of pressure sensi: tive adhesive on one end on the under surface as indicated at 55, and a second spot of pressure sensitive adhesive 56 on the upper side thereof opposite the spot 55. The extentof the area of adhesivemay obviously be varied but may be relatively short. Furthermore, the area of the adhesive 56 may be of a setting type if preferred. The end of the leader 54 which bears the adhesive is inserted between the free edge 53 of the, sheet material and the adjoining convolution of this material. As a result, the free edge of the sheet is anchored to the remaining convolution, thus preventing the unrolling of the sheet during handling of the carton before the opening thereof.

The leader 54 is shown as encircling the sheet material 52 and having its free edge 57 located beneath the tear strip 41. Thus the edge or end of the leader may be grasped when the carton is opened and may bepulled to. unwind the roll and to direct the marginal edge 53 of the sheet material 52 through the opening left by the tear strip 41. j Due to the upward direction of pull of the leader, the adhesive spot 55 will become disengaged and permit the roll of sheet material to be unwound.

As is indicated in Figure 3 of the drawings, the

flap extensions

33 and 35 extend into the interior of the core 51 at one end of the roll and the

flap extensions

36 and 37 extend into the core at the other end of the carto'n. The flap extensions may be located either on the front and rear walls as illustrated, or on the top and bottom walls so as to extend horizontally when the top panel 13.

is uppermost. The flap extensions are of such width as to frictionally resist the rotating of the core about these flap extensions and thus tend to hold the roll from rotating unless a pull is exerted upon the sheet. In other words, the construction is such as to resist rotation unless rotation of the roll is actually desired.

In Figure 10 of the drawings, I disclose a modified form of construction in which the roll of sheet material is indicated in general by the numeral 59 and the free end of the sheet is indicated by the numeral 60. In this arrangement, a spot of adhesive is indicated at 61 between the free end of the sheet and the next adjoining convolution. This arrangement holds the sheet material from unwinding about the core and holds the free edge 60 in a set position in the carton. As the roll is prevented from rotating accidentally by the flap extensions which have been described, the marginal edge of the sheet is readily accessible when the carton is opened.

In Figure 7 of the drawings I disclose a modified form of construction which is indicated in general by the letter B. This arrangement is very similar to the construction previously described and, accordingly, the body of the carton is not described in detail. The various carton panels are foldably connected along a line of fold 62 to end closing flaps 63, 64, 65 and 66. The various carton walls are also connected along a fold line 67 to closing

flaps

69, 70, 71 and 72. The

flaps

64, 65 and 66 at one end of the carton and the

flaps

70, 71 and 72 at the opposite end of the carton are generally rectangular inform and are designed to extend in superimposed relation in the usual way. However, the flaps 63 and 69 are connected with

flap extensions

73 and 74 which are connected to the flaps along

fold lines

75 and 76. The

flap extensions

73 and 74 are provided with arcuate side edges 77 and 79, respectively, which are shaped to fit the contour of the inner surface of the wall when the extensions incline inwardly and downwardly from the ends of the carton. The edges of these flaps rub against the interior of the hollow core and tend to resist rotation of the'core within the carton.

In Figures 11 and 12 of the drawings a modified form of construction is illustrated which is illustrated in gen era] by the letter C. This arrangement is in general similar to the constructions previously described and the carton is shown as having a front wall 80, a bottom wall 81, a rear wall 82, and a top wall 83. These various walls are provided with end closing flaps of the type described to close the ends of the carton and preferably to resist rotation of theenclosed core. A glue fiap 84 is hingedly connected to the forward edge of the front panel and is adhered to the inner surface of the front wall 80 near its upper extremity. A metal cutting edge is also preferably attached to the upper surface of the front wall 80 along its upper edge. N

In the particular arrangement illustrated, the top wall 83 is provided with a weakened line of separation such as a perforated line 86 which extends longitudinally from end to end thereof at a point materially spaced from the fold line connecting the top panel 83 to the glue flap 84'. Usually, the perforated line 96 is approximately mid way between the forward and rear edges of the top panel.

The ends of the perforated line 86 are connected by diagonally extending cut lines 87 and 89 which extend from the junctures of the weakened line 86 and the fold lines connecting. the top panel 83 to the closing flaps and the juncture between the top panel 83 and the glue flap 84. As illustrated, these cut lines 87 and 89 converge forwardly and inwardly. Accordingly, when pressure is exerted upon the portion of the top panel 83 forwardly of the weakenedline 86, the top panel is separated along the top panel throughout its length forming a flap hingedly connected to the glue flap 84 and which may incline downwardly into the interior of the carton to some extent as is indicated in Figure 12 of the drawings.

When the line of perforations 86 has been broken, it is possible to insert the thumb and fingers into, the

carton and to thread the extremity of the sheet material between the forward portion of the top panel and the rearward portion thereof. The sheet material is indicated in general by the numeral 90 and the free extremity 91 thereof is illustrated as extending through the top of the carton so as to overlie this top part.

In view of the fact that the flap which is formed by breaking the line of perforations 86 is the full width of the carton, the ends of the flap tend to bind against the end walls of the carton thus holding the flap in proper position to strip the outer lamination of material from the roll and to direct the material to the cutting edge 85.

In order to simplify the grasping of the free end 57 of the leader 54, or the end 60 of the roll of sheet material 59, the center portion of the tear strip is widened outwardly. The

cut score lines

46 and 47 are provided with outwardly

arcuated center portions

48 and 48, increasing the size of the opening intermediate its ends. The curved shape of the centers of the weakened lines does not interfere with the removal of the tear strip.

end panel intermediate the fold lines connecting it to the glue flap and to the adjacent panel of said series, end closure flaps on said panels secured in carton end closing relation, and a cylindrical core within said carton having sheet material wound thereupon.

tioned inwardly of, and adhered to, the edge of said other end panel to which said cutting edge is attached, a removable tear strip extending longitudinally across said one end panel intermediate the fold lines connecting it to the glue flap and to the adjacent panel of said series,

end closure flaps on said panels secured in carton end When the leader 57 is omitted, the stock at the end of i the roll may be cut away on either side of center to provide a narrow end extension which may be easily grasped. In other words, the leader may be integral with the roll of sheet material if preferred.

In accordance with the patent statutes, I have described the principles of construction and operation of my dispenser carton, and while I'have endeavored to set I forth the best embodiment thereof, I desire to have-it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
