ATTORNEYS 3,229,889 CELLULAR DISPLAY CARTONS George Vrana, Flushing, N.Y., assignor to Riegel Paper Corporation, New York, N.Y., a corporation of Delaware Filed Oct. 2, 1963, Ser. No. 313,247 Claims. (Cl. 229-28) The present invention relates to display cartons erectable from collapsed tubes and particularly to cellular display cartons which have exceptional rigidity in all lengths sand sizes. More specifically, the cellular display cartons of the present invention are of the general type which is constructed in a manner such that only the finished or printed surface of the carton blank is visible when the carton is erected and filled with merchandise to be displayed.

The display cartons of the present invention includes body portions, having base, side and end walls, and an integral divider structure which is adhesively secured to areas of the body portions in the formation of the collapsed carton tube. In accordance with the principles of the invention, containers may be provided in any length, including extra-long lengths which are desirable for unusual displays but which heretofore have been difiicult to manufacture economically in commercially acceptable forms. The cartons are divided into one or two rows of compartments by divider platforms which are glued between walls of the carton and have a series of spaced divider panels oldably suspended therefrom. The divider panels have integral tongue portions extending therefrom and arranged to act frictionally against the bottom wall. The combination of the glued platforms and the suspended divider panels with friction tongues acting against the bottom wall, in accordance with the principles of the invention, gives the cartons exceptional strength and great resistance to crushing regardless of the overall carton length. This is of especial importance in many of the contemplated applications which include the display packaging of fragile or delicate spherical objects such as Christmas tree ornaments, fancy fruits, and the like in extra-long, eye-catching display cartons.

The display cartons of the present invention are characterized by their ease of manufacture and require only a minimal number of folding and gluing steps to cornplete a attened carton tube, from which they may be easily and manually erected .into a completed, commercially desirable display unit.

To appreciate more fully the above and other aspects of the present invention, reference should be had to the following detailed description taken in conjunction with the accompanying drawings; in which:

United States Patent Oi 3,229,889 Patented Jan. 18, 1966 rice Referring to FIG. 1 of the drawings, a one piece carton blank 10, with its unfinished or printed side exposed, is cut and scored in accordance with the invention to provide the element-s of the new and improved display carton. For the sake of added clarity in the drawings, the letter a will be added to the reference numerals in FIGS. 2-5, where appropriate, to indicate the decorated or finished side. Specifically, the blank of FIG. l includes a rectangular bottom wall panel 11, typically having a length many times its width, and

side panels

12, 13 articulated thereto, along

longitudinal score lines

14, 15, respectively. As shown, the

side panels

12, 13 have end aps 12', 13 articulated thereto, and a decorative panel 16, having an adhesive coating 17 on its unnished face, is articulated to the side panel 12 along a score line 18. Attached to the remaining edges of the bottom wall panel 11 along

score lines

19, 20 are

end pan-els

21, 22. A pair of

tuck flaps

23, 24 having

locking tabs

25, 26 are connected to the last-mentioned aps along score lines 27, 2S, respectively.

In accordance with the invention, a divider structure, indicated generally at 29, is articulated to the side panel 13 along a longitudinal score line 30 and includes a glue- .carrying panel 31, a glue flap 32, and va divider platform 33 integrally supported therebetween along spaced

longitudinal score lines

38, 39. The panel 31 carries an adhesive coating 17 on its unfinished side while the glue flap 32 carries an adhesive coating 17' on its finished side 32a.

In accordance with the principles of the invention, the divider platform 33, includes a Series of straight 'cuts 47 and arcuate cuts 48 defining a plurality of divider panels 34, each of which has an oval friction tongue 35 joined therewith along a perforated hinge line 36. The cuts 48 are substantially arcuate but include U-shaped portions 49 coincident with transverse score lines 50 to facilitate bending of the divider panels out of the plane of the divider platform. T-he friction tongues are shaped such that pairs of three-cornered gusset portions 37 of the divider platform sections 33 remain to suspend the divider panels therefrom when the carton is erected, as will be described in detail hereinafter. The arcuate cuts 48 provide arcuate bearing surfaces 37 in the divider platform 33 for supporting spherical objects, such as glass ornaments which may be contained in the cells to be formed. Advantageously, the radius of the bearing surfaces 37 may be chosen with relation to the radius of the spherical lobjects being packaged and the cell `size to retain such fragile objects immovably in the cells by slight interference fits. g

The end portions of the divider platform have

end flaps

40, 41 articulated thereto along

score lines

42, 43. These end iiaps rigidify the end platform sections when the carton is erected. As shown in FIG. 1, U-shaped cuts 44, 45 define tabs along edges of the end flaps which form locking slots 46 (FIG. 2) when the carton is erected.

'In accordance with the principles of the invention, carton blanks may be simply and quickly formed into flat tubes from which display cartons may be easily formed by hand through the squaring of the tube. To this end the blank shown in FIG. l may be eiiiciently folded and glued into a tube using conventional machinery and methods as follows: Initially, the decorative panel 16 is folded along the score line 18 and adhered to the unfinished side of the side panel 12. Then the divider panel is folded along the score line 30 and the glue panel 31 is joined to the unfinished side of the panel 13. The carton tube is completed by a third folding step in which the side panel 12, with the decorative panel 16 adhered thereto, is folded over the divider panel to secure the glue iiap 32 adhesively to the decorative panel 16.

A display carton embodying the principles of the invention and having a single row of compartments may be manually erected by squaring the flat-folded carton tube so that the

side walls

12, 13 are perpendicular to the `bottom 11, as shown in FIGS. 2-5. The ends of the display carton may then be erected by folding the

platform flaps

40, 41 downwardly to form the locking slots 46', folding the end flaps 12', 13 inwardly, folding the end panels upwardly, folding the tuck aps over the end flaps, and inserting the locking tabs into the locking slots to lock the carton in its erected form. Individual compartments or cells are formed easily and quickly by pressing the divider panels downwardly out of the plane of the platform panel 33 and into a perpendicular relation therewith as best shown in FIGS. 4 and 5. The appended friction tongues 35 will bend along the line of perforation and will tend to hold the divider panels in their desired cell-forming positions. Furthermore, the tongues function importantly to provide transverse carton rigidity and to give added resistance to crushing.

It should be appreciated from FIGS. 2-5 that in its erected condition the display carton of the invention has only decorated or finished surfaces exposed above the plane of the divider platform, which, as illustrated, is advantageously above the center line of the side walls. It is to be kunderstood that the term decorated surface includes printed surfaces or the more attractive surface of a paperboard which has a reverse side having `suitable properties of strength but a less attractive appearance. Upon cmopletion, the carton may be overwrapped with cellophane or the like, to provide an especially attractive package. Moreover, the carton lends itself to construction in unusually long, eye-catching lengths, due to the structural rigidity provided at all sections therealong by the friction tongues and the glued

panels

31, 32.

An alternate embodiment of the invention, having twin rows of cells and substantially the same advantages and attributes of the carton of FIGS. 1 5, may be constructed from the carton blank 60 shown in FIG. 6 with its unfinished side up. In FIGS. 7-9, for more clarity of disclosure, the finished or decorated side of the carton blank will be indicated by the addition of the letter a to the reference numerals where appropriate.

Specifically, the carton blank 60 includes a rectangular base panel 61, having

side wall panels

62, 63 and

end wall panels

64, 65 articulated thereto along score lines 6669, respectively. The

end wall panels

64, 65 have

tuck aps

66, 67 connected thereto along

crease lines

68, 69, while the side wall panels have end flaps 62', 63', hingedly connected thereto along

score lines

70, 71, respectively.

In accordance with the principles of the invention, the

side wall panels

62, 63 have divider structures, generally indicated at 72, 73, articulated thereto along

score lines

74, 75, respectively. The

divider structures

72, 73 are similar to divider structure 29 described hereinabove, and include a divider platform 76 having divider panels 77 and friction tongues 78 formed therein in the same manner that the divider panels 34 and tongues 35 of the single row carton are formed. Thus, the divider platform 76 also includes platform fla-

ps

79, 80, U-shaped locking cuts 81,

longitudinal score lines

82, 83, and threecornered portions 84. Similarly to the carton blankof FIG. l, the

divider structures

72, 73 include glue panels 85, S6, respectively, and are integrally connected therealong to the

side wall panels

62, 63. The glue panels have adhesive 59 applied to their unfinished sides.

In the two-row carton construction, the

divider structures

72, 73 have supporting

wall panels

87, 88 articulated to the platforms 76 along score lines 83. The supporting wall panel 87 has a series of legs 89 disposed along the free edge thereof, each leg having a glue flap 90 associated therewith along a crease 91. Likewise, the supporting wall panel S8 has a series of legs 92 disposed along the Vfree edge thereof, each leg having a glue ap 93, carrying adhesive 59 on its unfinished side, associated therewith along a crease 94. However, in accordance with the invention and as shown clearly in FIG. 6, the

legs

89, 92 are disposed along alternate longitudinal areas of the blank 60. Thus, the legs 92 are located opposite openings 95 between the legs 89, andthe legs 89 are disposed opposite openings 96 between the legs 92. It will be appreciated that in the manufacture of the carton of the invention a series of blanks may be laid out consecutively on a sheet of paperboard with the

legs

89 and 92 interlocked, or nested, to realize a savings in paperboard. The structural purpose of this specific relationship will he explained in detail hereinafter.

A flattened carton tube for the `two-row embodiment of the invention may be formed simply and expeditiously by only two folds which may be performed consecutively or simultaneously, as desired or found necessary. Specifically, the divider structures 72,. 73 .are folded inwardly along

score lines

74, 75. The supporting wall panels are then adhesively secured to the base panel 61 ,in a dovetailed or interlocked fashion, while the

glue panels

85, 36 overlie and are adhesively secured to the` upper portions of the

side wall panels

62, 63. Thus, in the flat, folded condition, the score lines-91, 94 will lie along the central longitudinal axis of the base panel 61 and the glue flaps 90, 93 will lie alternately to either side thereof in the

openings

96, 95, respectively.

Erection of the two-row display carton of the invention may be accomplished simply by squaring `each of the divider panels, substantially as shown in FIGS. 7 and 8f folding the platform flaps 79, downwardly to form` locking slots 96, folding the end flaps 62', 63 inwardly, folding the

end panels

64, 65 upwardly, and then inserting locking tabs 97 of the

tuck iiaps

66, 67 into the locking slots 96. Completion of the individual compartments is effected, in a manner similar to that used in the single row carton, by depressing the divider panels 77 from `the plane of the divider platform 76, so that they are sub` stantially perpendicular to the base panel 61 and `maintained in that position by the friction tongues 78, as shown best in FIGS. 8 and 9.

The double row carton, like the single row carton, is unusually rigid and is adaptable to be manufactured in any length without sacrifice of strength. As shown in FIG. 9, the supporting

wall panels

87, 88 cooperate to form a two-ply spine for the carton which additionally i contributes to the overall strength of the carton.

The display cartons of the present invention provide a decorative and rigid structure particularly useful for holding fragile objects which may be safely contained `therein and overwrapped to provide a neat, attractive, and commercially acceptable display package. Moreover, the cartons may be manufactured simply and economically with existing machinery and in any reasonable length.
