United States Patent 3,135,457 PLURAL CARTON CONTAINING SEPARABLE UNlTS Edward J. Risucci, 3751 86th St, Jackson Heights 72, N.Y. Filed Jan. 18, 1963, Ser. No. 252,457 4 Claims. (Cl. 229-51) This invention relates to plural cartons and, more particularly, to plural cartons of separable units fabricated from a unitary blank.

It is well known in the art to fabricate plural cartons from a single blank. However, these blanks have been rather complex and non-symmetrical in design, requiring several punching and assembly operations.

Accordingly, it is a broad object of the present invention to provide a carton of the character described which can be fabricated from a unitary blank of simple and symmetrical design.

The blank consists of two separable units squared out on either side of central perforated tear line. A pair of front rectangular panels are separably connected by the perforated tear line. Adjacent the front panels are a pair of inner side panels defined from the front panels by score lines formed during the die punching operation. A pair of rectangular panels are attached to and defined from the inner side panels by score lines. A pair of outer side panels depend from the rear panels defined by score lines, and tabs are connected to the outer side panels and are also defined by score lines therefrom. End slots are connected to all of the panels and defined therefrom by score lines. Adhesive means are located on the tabs and several of the end flaps to allow the carton units to be securely closed. Finally, the outer pair of side panels have openings to allow egress of the contents of the separable units.

In a preferred embodiment of the invention, the front wall panels are connected by a single ply accordion flap having a perforated score line at its center. Furthermore, two of the diagonally disposed end flaps depending from the front panels have depending side flaps extending somewhat beyond the width of the accordion flap. When the carton is in its assembled condition, the side flaps extend into the separable units between the end flaps and panels, and when the units are separated, the side flaps serve as a cover for the openings in the side panels.

Thus, it is a more specific object of the present invention to provide a plural carton whose units are securely attached, but may be detached by tearing along a perforated score line for individual use.

It is a further object of the present invention to provide a plural carton having an accordion flap to allow a certain amount of variant movement.

Yet another object of the present invention is to provide a carton of the character described in which the units, when separated, may be maintained and utilized completely independent of each other.

Yet a further object of the present invention is to provide a plural carton of separable units having openings for each unit to permit egress of the contents, and a flap to cover the openings when they are not being used.

Still another object of the present invention is to provide an invention of the character described which will be inexpensive to manufacture, easy to assemble, and yet reliable and efficient to a high degree in use.

Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings which form material parts of this disclosure. The invention accordingly consists in the features of construction, combination of elements, and arrangement of parts, which will be ex- 3,135,457, Patented June 2, 1964 emplified in the construction hereinafter described, and of which the scope will be indicated by the appended claims.

FIG. 9 is a front perspective view of the embodiment of FIG. 8;

FIG. 10 is a rear perspective view of the embodiment of FIG. 8;

FIG. 11 is a cross sectional view taken along line 11-11 of FIG. 10; and

FIG. 12 is a perspective view of one of the separable units of the embodiment of FIG. 8.

Referring to the drawings and in particular to FIG. 1, there is shown a unitary blank 10 which may be die cut by any well known means. The blank consists of a pair of identical and symmetrical left and right front panels 11 and 12 disposed upon opposite sides of a single ply accordion flap 13 having a tear line 14 coincident with the axial central line of the blank. Said panels are generally rectangular in shape and are defined from said accordion flap by score lines 15 and 16. Symmetrical left and right

inner side panels

17 and 18 are located outwardly of said front panels 11 and 12 and are defined therefrom by

score lines

19 and 20. Said inner side panels are also generally rectangular in shape, being the same length but of substantially lesser width than said front panels.

symmetrically disposed left and right

rear panels

21 and 22 are located outwardly of said

inner side panels

17 and 18 and are defined therefrom by score lines 23 and 24. Said rear wanels are generally rectangular in shape and are of the same dimensions as said front panels. Left and

right side panels

25 and 26 are symmetrically disposed and are dependent from said inner panels, and defined therefrom by

score lines

27 and 28.

Outer side panels

25 and 26 are substantially identical to

inner side panels

17 and 18 dimensionally.

Diagonally disposed within said outer side panels are

openings

29 and 30 to permit egress of the contents of units.

Left and

right end tabs

31 and 32 are attached to said

outer side panels

25 and 26 and defined therefrom by score lines 33 and 34.

Outer side flaps

25 and 26 have depending

end flaps

25a, 25b, and 26a, 26b respectively, defined from said flaps by the

respective score lines

35, 36, 37 and 38. Similarly said

inner panels

21 and 22 have

corresponding end flaps

21a, 21b, 22a, and 22b defined therefrom by

score lines

36, 37, 38 and 39; and

inner side panels

17 and 18 have

end flaps

17a, 17b, 18a and 18b defined therefrom by

score lines

40, 41, 42 and 43, respectively.

Said front panels 11 and 12 have diagonally disposed

end flaps

44 and 45 equal in width to said panels and having

respective side flaps

46 and 47 depending from said end flaps. Said side flaps are of somewhat greater width than the width of accordion flap 13 and hence the

end flaps

48 and 49, the other end fiaps depending from said front panels are of a somewhat lesser width than said panels.

An adhesive, such as glue, may be placed on the surface of the end tabs and

end flaps

44, 45, 4-3 and 49.

Referring now to FIG. 4, the blank is folded over so that said front and rear panels and said side panels are in parallel relation, the adhesive surface of said end tabs being adhered to the inner surface of said front panel. The end tabs are then folded as shown in FIG. 2, said inner side tab 47 being placed over

tabs

25b and 17b and below

tabs

21b and 49. Similar assembly enclosure operation is apparent for the rest of the carton. The accordion ply is unhampered in its movement as illustrated by FIG. 3 and the separable units are accordingly capable of longitudinal movement therewith.

When it is desired to separate the units, the user need simply pull on the two units, thus causing the accordion fold to flatten and thentear along the perforated tear line. This affords the additional feature for providing a leverage means to allow gripping for easy separation of the units. The flap 47 (FIG. 7) serves as a closure for opening 30 during storage.

Referring to the modified form of the invention shown in FIG. 8, there is seen a unitary blank 100 comprising two symmetrically placed separable unit assemblies consisting of left front and

right panels

110 and 12%) connected to left and right

inner panels

210 and 220 by left and right

inner side panels

170 and 180 being defined from each other by

score lines

23d, 190, 200 and 249.

End tabs

310 and 320 are connected to said inner panels by

outer side panels

250 and 260 being defined therefrom by

score lines

330, 270, 230 and 340. Said outer side panels have diagonally disposed openings 2% and 300.

Said inner and outer side panels and said inner panels have

corresponding end flaps

250a, 250b, 2160, 216b, 170a, 170b, 180a, 180b, 220a, ZZ-llb, 26th: and 26%; defined from said panels by

score lines

356, 3643, 361M, 370, 380, 380a, 390, 400, 410, 42% and 430. Said

front panels

110 and 120 have depending end flaps t), 51, 52 and 53, all being a width coincident with said panels and being defined therefrom by

score lines

54, 55, 56 and 57. Said panels are separably united by a perforated tear line 140.

The assembly is in a similar manner to that of the preferred embodiment, as shown in FIG. 11, except there is no accordion flap present, nor are there any side flaps extending into the adjacent unit.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.

What is claimed is:

l. A plural carton of separable units fabricated from a unitary blank comprising a pair of front wall panels connected by a single ply accordion fiap; a pair of rear wall panels connected by a pair of inner side panels to said front panels; a pair of outer side panels connected to said pair of rear wall panels and having openings diagonally disposed on said blank; tabs depending from said outer side panels; end flaps depending from said panels whereby the ends of the separable units may be completely enclosed; side flaps depending from diagonally disposed end flaps attached to said front panels; whereby when the blank is in its assembled condition said side flaps extend between said end flaps and said panels and when the units are separated said side flaps are used to close said openings in said outer side panels.
