More particularly, this invention relates to cartons for dispensing from a roll stock a sheet-form material such as film, foil, wax paper, or the like.

In use, the cover member of a dispensing carton tends to fly open as the sheet-form material is withdrawn therefrom. Also, on occasion the terminal portion of the roll stock extending out of the dispensing carton tends to slip back into the carton.

It is an object of the present invention to obviate the forementioned shortcomings of dispensing cartons and to provide a dispensing carton having a positive reclosure lock for the carton.

It is a further object of this invention to provide means for preventing the roll stock from slipping back into the carton.

Still otherobjects of the present invention will present themselves to one skilled in the art upon reference to the ensuing specification, the drawings, and the claims.

SUMMARY OF THE INVENTION The present invention contemplates a dispensing carton having a generally polygonal cross-section and comprising a series of at least four hingedly interconnected side wall panels. The first side wall panel in said series is overlapped by the last side wall panel in the series and is adhesively affixed to the first side wall panel. A severance line is provided in the last side wall panel. Terminal flaps are hingedly connected to each of the side wall panels. The adjacent terminal flaps of the penultimate and the last side wall panel in the series are joined in an overlapping relationship and, together with the penultimate panel and the last panel, define a cover member for the carton. The adjacent terminal flaps of the first to the antepenultimate side wall panels, inclusive, are joined in an overlapping relationship and together define end walls of the dispensing carton. The cover member is provided with a notch therein situated at each end of the cover member and each end wall is provided with a coplanar lock tab which projects through and engages one of the notches in the cover member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the accompanying drawings, all parts are numbered and the same numbers identify the same parts in the several FIGURES.

Referring to FIG. 1, carton blank 10 comprises bottom panel 11, and front side wall 12 and rear side wall 13 both hingedly connected to bottom panel 11. Cover top panel 14 is hingedly connected to rear side wall 13, and cover front panel 15 is hingedly connected to cover top panel 14 and is adapted to overlap front side wall 12 when the carton is erected. Cover front panel 15 is provided with glue strips 16 and 17 which are delineated by

severance lines

18 and 19 comprising a series of spaced longitudinal slits or perforations that terminate in transverse slits 21 which add to the flexibility of glue strips 16 and 17 and also minimize disfiguring fractures. Glue strips 16 and 17 are adapted for adhesive affixation to front side wall 12 by means of an appropriate adhesive, e.g., a hot melt adhesive.

Cover front panel 15 is further provided with notches or

cutouts

22 and 23 situated at opposite ends of cover front panel 15 and adjacent to the hinged connection along score 24 between cover front panel 15 and cover top panel 14. For purposes that will be discussed in more detail hereinbelow,

cuts

25 and 26 optionally can be provided beyond notch 22, and

cuts

27 and 28 optionally can be provided beyond notch 23.

Cuts

25, 26, 27 and 28 usually extend beyond the respective notches for a distance substantially equal to the depth of the respective notches.

Cover top

panel end flaps

29 and 30 are hingedly connected to cover top panel 14, and cover front

panel end flaps

31 and 32 are hingedly connected to cover front panel 15.

End flaps

31 and 32 are adapted to

underlie end flaps

29 and 30 and to be adhesively attached to the latter. When the carton is erected,

end flaps

29, 30, 31 and 32, together with respective top panel 14 and front panel 15, define a dispensing carton cover member having notches 22 in the front face thereof.

Rear side

wall end flaps

33 and 34 are each hingedly connected to rear side wall 13, and front side

wall end flaps

35 and 36 are hingedly connected to front side wall 12. Bottom

panel end flaps

37 and 38 are each hingedly connected to bottom panel 11 and are adapted to overlie and to be adhesively affixed to the respective adjacent rear side

wall end flaps

33 and 34 anc the front side

wall end flaps

35 and 36. Preferably the configuration of bottom

panel end flaps

37 and 38 is such that

end flaps

37 and 38 are substantially coextensive with the transverse cross-sectional area of the dispensing carton, i.e., the width of bottom

panel end flaps

37 and 38 is substantially the width of bottom panel 11 and the length of the bottom

panel end flaps

37 and 38 is substantially the width of rear side wall 13. In any event,

end flaps

33, 35 and 37 are adapted to be joined in an overlapping relationship so as to define one end wall of the dispensing carton. Similarly,

end flaps

34, 36 and 38 together define the other end wall of the dispensing carton.

Bottom

panel end flaps

37 and 38 are further provided with

coplanar lock tabs

39 and 40 which are situated so as to project through and engage

notches

22 and 23, respectively, when the dispensing carton is erected.

Slits 41 and 42 in front side wall 12 extend from the top or leading edge 43 of front side wall 12 to about the line of attachment of glue strips 16 and I7 and serve to facilitate the insertion of cover front panel 15 behind front side wall 12 in an erected carton once the carton has been opened by

parting severance lines

18 and 19. Similarly,

optional notches

44 and 45 further facilitate the insertion of cover front panel 15.

Cutter blade 46 is affixed to bottom panel 11 in any convenient manner, e.g., by means of integral lugs punched inwardly therefrom (not shown) and the cutting edge of blade 46 operatively extends across hinged connection between bottom panel 11 and front side wall 12, i.e., when the dispensing carton is erected, the cutting edge of blade 46 projects or extends beyond front side wall 12. Cutter blade 46 also provides a reinforcement for the edge of bottom panel 11 which is subjected to stress during the cutting operation.

A dispensing carton can be erected from blank by first folding blank 10 over on itself so that cover front panel overlaps front side wall 12 and then adhesively attaching panel 15 to wall 12 underneath glue strips 16 and 17. The resulting carton tube is then squared in a conventional manner and a roll of a desired sheet-form material inserted therein. End closure is then achieved by folding in and adhesively securing the terminal flaps.

Referring to FIG. 2,

end flaps

33 and 35 are first folded in, followed by end flap 37, and then glued together. As end flap 37 is folded inwardly, lock tab 39 is placed in notch 22. Thereafter, end flap 31 of cover front panel 15 is folded inwardly and end flap 29 of cover top panel 14 folded over end flap 31 and adhesively secured thereto.

The notches in cover front panel 15, such as notch 22 shown in FIG. 2, need only be large enough to accommodate lock tab 39. However, in order to facilitate reinsertion of lock tab 39 in notch 22 once the cover member has been lifed up and is reclosed, it is desirable to make notch 22 somewhat larger than the crosssectional area of lock tab 39. By providing cuts or slits and 26, however, the overall dimensions of notch 22 can be minimized.

Another embodiment of the present invention is illustrated in FIGS. 3 and 4. Paperboard blank 47 comprises bottom panel 48 to which are hingedly connected front side wall 49 and rear side wall 50. Cover top panel 51 is hingedly connected to rear side wall 50, and cover front panel 52, in turn, is hingedly connected to cover top panel 51. Tear strip 53 is substantially coextensive with cover front panel 52 and is delineated by severance line 54 which comprises spaced slits 55 connected by perforations 56. Transverse slits 57 enhance the flexibility of tear strip 53.

Cutouts

58 and 59 at both ends of tear strip 53 generate tabs at opposite ends of tear strip 53 and facilitate tearing or severing.

Cover front panel 52 is further provided with notches 60 and 61 which serve the same purpose as

notches

22 and 23 in the embodiment shown in FIGS. 1 and 2.

Spaced cut scored regions 62 are provided in front side wall 49 and tear strip 53 is adapted to be adhesively secured thereto.

Cover top panel end flaps 63 and 64 are hingedly connected to cover top panel 51 and cover front panel end flaps 65 and 66 are hingedly connected to cover front panel 52 between cutout 59 and notch 60 and between cutout 58 and notch 61, respectively. End flaps and 66 are adapted to underlie respective end flaps 63 and 64 and to be adhesively attached thereto. When the dispensing carton is erected,

panels

51 and 52, together with end flaps 63, 64, 65 and 66, define a dispensing carton cover member provided with notches 60 and 61 in the front face thereof.

Rear side wall end flaps 67 and 68 are each hingedly connected to rear side wall 50, and front side wall end flaps 69 and 70 are hingedly connected to front side wall 49. Bottom panel end flaps 71 and 72 are hingedly connected to bottom panel 48 and are provided with lock tabs 73 and 74 which engage notches 60 and 61, respectively, and project therethrough when a dispensing carton is erected from blank 47.

End flaps 71 and 72 are adapted to overlie and to be adhesively affixed to the respective adjacent rear side wall end flaps 67 and 68 and the front side wall end flaps 69 and 70, and the end flaps together define the end walls of the dispensing carton.

Slits 75 and 76 in front side wall 49 as well as

notches

77 and 78 facilitate insertion of cover front panel 52 behind front side wall 49 after an erected carton has been opened for the first time.

Cutter blade 79 is secured to bottom panel 48 so that the cutting edge thereof operatively extends across hinged connection between bottom panel 48 and front side wall 49.

A dispensing carton can be erected from blank 47 in a manner similar to that described hereinabove for blank 10. That is, blank 47 is folded over so that cover front panel 52 overlaps front side wall 49 and appropriate adhesive areas provided on the underside of tear strip 53 are in substantial registry with cut scored regions 62. Panel 52 is then adhesively attached to front side wall 49 and the resulting carton tube squared in a conventional manner. After container contents has been inserted in the produced tube, end closure is achieved by folding inwardly and gluing the terminal flaps.

Referring to FIG. 4, end flaps 67 and 69 are folded inwardly first and then end flap 71 folded thereover and the flaps adhesively secured to each other. As end flap 71 is folded inwardly, lock tab 73 is received in notch 60. Thereafter end flap 65 is folded inwardly and end flap 63 is folded over end flap 65 and attached thereto by gluing. Notches 60 and 61 in cover front panel 52 are made sufficiently large so that the lock tabs such as lock tab 73 can be accommodated therein and can be reinserted therein once the dispensing carton has been opened by raising the cover member defined by

panels

51 and 52 and the corresponding end flaps.

A carton erected from blank 10 and which has been opened and then reclosed is shown in FIG. 5. Lock tab 39 engages notch 22 and projects therethrough, thereby retaining carton cover member 81 firmly in place as film 80 is withdrawn from the carton. In the embodiment shown in FIG. 5, film sheet 80 is contained in the carton as a roll stock, and is separated from the roll stock near cover top panel 14 and then passes downwardly between front side wall 12 and cover front panel 15. Lock tabs such as tab 39 engage cover front panel 15 and prevent cover member 81 from opening as film sheet 80 is withdrawn from the dispensing carton. Film sheet 80 can also be made to separate from the roll stock near bottom panel 11 by merely reversing the position of the roll stock within the dispensing container, in which event the withdrawn film sheet first passes upwardly and over the upper edge of front side wall 12, and then downwardly between front side wall 12 and cover front panel with the upper edge of front side wall 12 acting as a brake on the film sheet being withdrawn and preventing the film sheet from slipping back into the carton.

A preferred manner of reclosure for the dispensing carton of this invention when film sheet 80 is contained in the carton as roll stock and is separated therefrom near cover top panel 14 is shown in FIG. 6. Cover front panel 15 is tucked in behind front side wall 12 and film sheet 80 first passes downwardly and over the lower edge of cover front panel 15, and then upwardly between cover front panel 15 and front side wall 12 as film sheet 80 leaves the dispensing carton. A desired length of film sheet 80 can then be severed by folding film sheet 80 back againstcutter blade 46 and pulling. The lower edge of cover front panel 15, together with the inner surface of front side wall 12, act as a brake which prevents film sheet 80 from slipping back into the carton.

The foregoing discussion and the drawings are intended to be illustrative but are not to be taken as limiting. Still other variations and rearrangements of parts are possible and will readily present themselves to the skilled artisan.
