Detailed Description of the Drawings
Referring now to the drawings in detail, and more particularly to FIG. 1, there is illustrated an exploded view of a carton construction A which, according to the present invention, includes a container tray B, a tray cover C, and a container sleeve D. The container tray B as shown in FIG. 1 is in its article receiving position. Tray cover C may be and is shown to be identical in construction to that of tray B except that it must be slightly larger than tray B so that it may be telescopically lowered over tray B in the direction of the downwardly directed arrows. The subassembly of cover C and tray B may then together be inserted into container sleeve D in the direction of arrows directed toward northwest in FIG. 1, and when thus completely assembled sleeve D may be turned on end and placed, for example, on a book shelf.
Looking now to FIGS. 2, 3 and 4, there is illustrated first in FIG. 2 a blank B,C for constructing either container tray B or tray cover C of FIG. 1. Since these members are identical in construction except for size it is considered sufficient to describe one for the both. Consistent with the general practice and terminology of the carton manufacturing industry, wherein the inner surface of a carton is not or may not be lined or finished and is referred to as the bottom liner surface, and the outer surface of a carton is lined or finished and is referred to as the top liner surface, FIG. 2 shows the inner surface or bottom liner of the tray or cover which will be formed therefrom. To distinguish bottom liner surfaces and edges from corresponding surfaces and edges unprimed reference numerals are used in FIGS. 2-4 to designate bottom liner surfaces and edges, whereas primed reference numerals are used in FIGS. 3 and 4 to designate top liner surfaces and edges. Similar numbers primed and unprimed are used herein to designate surfaces or edges on opposite sides of a common structural piece.
Referring now to FIGS. 2, 3 and 4 in detail, a blank B is seen to have a bottom panel 11 with main side wall panels 12 integral therewith along opposite fold lines or edges 13 and auxiliary side wall panels 16 extending from main side wall panels 12 along fold lines or edges 15. On opposite ends of each main side wall panel extend end flaps 14 along fold line or edge 17. On opposite ends of bottom panel 11 are fold lines or edges 31 from which main end wall panels 18 extend. Each main end wall panel 18 includes an auxiliary end wall panel 20 along a fold line or edge 21 and side flaps 22 along fold line or edge 23. The end flaps 14 and side flaps 22 are formed separate and independent of each other by cut line 19.
To facilitate handling in shipment of large quantities of carton members to users, the cartons must be shipped in flat or nearly flat condition, yet such carton members should be shipped in at least partially assembled condition for the convenience of the user. To this end, adhesive G is applied in the stippled areas on bottom liner surface of auxiliary side wall panels 16 and side flaps 22, after which auxiliary side wall panels 16 are folded 180.degree. along fold lines 15 and adhered to main side wall panels 12 and side flaps 22 are folded 180.degree. along fold lines 23 and adhered to main end wall panels 18, as seen in FIG. 3, which shows the degree of assembly of carton member B when it is shipped to the user thereof. In completing the assembly of tray member B for use according to the present invention, each main end wall panel 18 is folded 90.degree. along fold line 31 each end flap 14 is folded 90.degree. along fold line 17, after which main side wall panels 12 together with auxiliary side wall panels 16' and end flaps 14 are turned 90.degree. along fold line 13, as illustrated in FIGS. 3 and 4. Adhesive applied to outer or top liner surface of either end flap 14' or side flap 22' will provide a strong bond between top liner surfaces 14' and 22' when brought in contact with each other. Thereafter, to complete the assembly of tray member B, auxiliary end wall panels 20 are folded 180.degree. along fold line 21 with adhesive G applied to the bottom liner surface thereof if desired. In any event, auxiliary end wall panel 20 is folded along fold line 21 and pressed against bottom liner surfaces of end flaps 14 and of main end wall panels 18. As noted above, container cover C because of its similarity to tray B will be assembled in similar fashion.
It is clear in FIGS. 1 and 4 that as assembled and erected tray B and cover C will have only outer or top liner surfaces exposed to the exterior thereof. Moreover, only folded edges will appear along the exterior of tray B and cover C. All raw edges are turned into the interior of the tray B and cover C so that only folded edges 13', 31', 17', 23', 15' and 21' appear along the exterior of tray B and cover C. In this manner, a carton member B or C is provided which is neat in appearance; reinforced and sturdy along all surfaces except at the bottom panel 11; securely joined at intersections of side wall and end wall portions. In this regard, each intersection of wall portions of tray B, for example, is provided with an end flap 14 and a side flap 22 which are separate and independent of each other and which joint is formed by folding one such flap 180.degree. and adhering it bottom liner to bottom liner against a main wall panel, then the other of such flap is adhered top liner to top liner against the one such flap.
Referring now to FIGS. 5, 6, 7 and 8 in detail, a blank D is seen to have along a bottom liner surface a first main panel 50 having second main panel 54 integral therewith along one edge, a third main panel 60 integral with second main panel 54 and an assembly flap 80 integral with third main panel 60 along edges parallel to the edge between panels 50 and 54. On the side of panel 50 opposite to panel 54 extends a fourth main panel 56 with an auxiliary or reinforcement panel 62 integral therewith along a fold line. The blank D further includes auxiliary or reinforcement panels 52, 64 and 78 extending from lower edges of main panels 50, 54 and 60, respectively, and integral therewith and an auxiliary or reinforcement panel 74 along the upper edge of main panel 60. Along the upper edge of main panel 50 is an additional main panel 58 with trapezoidal end flaps 82,84 extending from opposite ends thereof. Extending along the top edge of main panel 58 is an auxiliary or reinforcement panel 72 provided at opposite ends thereof formed with trapezoidal cutouts or notches adjacent to end flaps 82 and 84, which cutouts are generally congruent with but facing in a direction opposite to the respective flaps 82 and 84 adjacent thereto. At the upper edges of main panels 54 and 56, respectively, extend foldable flaps 66 and 68 formed by cutting at least along two sides of trapezoidal flaps 82 and 84. Main panel 56 is also provided at its lower end with a foldable flap 70. Additionally, blank D is formed with notches or cutouts 51, 53, 55 and 57 along adjacent sides of main panels 50 and 52 and main panels 60 and 78, respectively.
Sleeve D is partially assembled for the convenience of the user and to facilitate handling in shipment it is assembled only to the point where it may be shipped in flat condition as seen in FIG. 6. To facilitate assembly, adhesive is applied to the areas stippled or designated G in FIG. 5 and as auxiliary panels 52,64 and 78 are folded 180.degree. about their fold lines they are adhered to main panels 50, 54, and 60, respectively, with top liner surfaces 52', 64' and 78', respectively, in view in FIG. 6. The partially assembled form of blank D also includes folding auxiliary panel 72 and end flaps 82 and 84 180.degree. about their respective fold lines and thereafter adhered to main panel 58 with top liner surfaces of end flaps 82' and 84' fitting in the cutouts at opposite ends of auxiliary panel 72' as seen in FIG. 6. Auxiliary panel 62 and foldable flap 70 are seen to each have at least one side formed along the extension of a common side and of additionally parallel sides at opposite ends of the common side so that when auxiliary panel 62 and foldable flap 70 are turned in at 180.degree. and adhered to main panel 56 no overlapping occurs between the surfaces of auxiliary panel 62' and foldable flap 70' as seen in FIG. 6, at which time the partially assembled carton member D is ready for shipment.
When the user is ready to erect and completely assemble sleeve D foldable flaps 66 and 68 are turned up 90.degree. about the respective fold lines thereof, auxiliary panel 74 is turned in at 90.degree. , main panel 58 is turned in at 90.degree. with auxiliary panel 72' and end flaps 82' and 84' attached thereto as seen in FIG. 7. Main panel 60 is turned up 90.degree. with auxiliary panel 78' attached thereto as seen in FIG. 7 and with auxiliary panel 74 on the exterior of foldable flap 66. Adhesive applied to the outer or top liner surface of foldable flap 66 will then adhere same to auxiliary panel 74. Next panels 50, 52, 58, 72, 56, 62 are together raised 90.degree. about the fold line between main panel 50 and main panel 54 with adhesive applied to the top liner surfaces 82', 72' and 84' which are then affixed against the outside of panel 74 to secure same together. Next foldable flap 68 is folded in against panel 74 and adhered thereto in mirror image to foldable flap 66 leaving only surfaces 62' and 70' to be attached. Assembly of sleeve D is completed by tucking assembly flap 80, having adhesive applied to the top liner surface thereof against the adjacent portions of top liner surfaces of auxiliary panel 62' and flap 70' pressed thereagainst as seen in FIGS. 1 and 8.
The completely assembled sleeve D comprises a member in which each wall panel is of at least two ply and all external edges are folded so that no raw edges are visible except for the cutouts at 51, 53, 55, 57.
With the carton members B, C and D assembled together in which articles of a game, for example, are placed into tray B and cover C lowered thereover as suggested in FIG. 1, the members B and C may then be together slipped into sleeve D providing a carton construction having no raw edges exposed to view except at the notches 51, 53, 55, 57 which facilitate separation of the members. Moreover, pasteboard containers of very sturdy construction are thus provided.
It will be obvious to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown in the drawings and described in the specification.
