Definitions
- a collapsible container is formed from a blank of paperboard and has opposed pairs of hingedly interconnected first and second sidewalls which have first and second closure flaps hinged respectively thereto.
- the container is erected in the usual manner to form a tubular structure.
- the inner surface of each of the first closure flaps and the outer surface of each of the second closure flaps is covered with adhesive coating, the adhesive being of the self-sticking type so that a surface coated therewith will adhere only to another similarly coated surface.
- This invention relates to a collapsible container formed from a unitary blank of paperboard and, more particularly, to a collapsible, self-sealing container having adhesively coated closure flaps, the flaps being folded in such a manner as to prevent undesirable adhering of coated surfaces to one another when the container is in collapsed condition.
- the present invention overcomes the disadvantages of the prior art and provides a paperboard container having the necessary interior or exterior surfaces of the closure flaps coated with self-sticking adhesive so that an erected container can be readily sealed, but, at the same time,
- FIG. 1 is a perspective view of the container of the present invention representing the first embodiment thereof;
- FIG. 2 is a side elevational view of the container of FIG. 1 when the container is in a collapsed condition;
- FIG. 3 is a fragmentary perspective view of the container representing the second embodiment of the present invention.
- FIG. 4 is a fragmentary view showing portions of the flaps of container illustrated in FIG. 3 when the flaps are being folded.
- FIG. 1 there is shown a container, generally designated 10, formed from a unitary, suitably cut and scored blank of foldable paperboard, or the like.
- the container is shown in the erected position and has opposed pairs of first sidewalls 12 and 14 and second sidewalls 16 and 18.
- a narrow panel 20 is hinged to the free edge of the first sidewall 12 along a hinge line 22 and is placed in an overlying relationship to the marginal area along the free edge of the second sidewall 18.
- the panel 20 is secured by any suitable means to the marginal area of the wall 18 to provide a manufacturers joint, as the same is known in the art of container manufacturing the first sidewall .12 is hinged to the second sidewall 16 along a hinge line 24, while the second sidewall 16 is hinged to the first sidewall 14 along a hinge line 26. Similarly, the wall 14 is hinged to the wall 18 along a hinge line 28.
- First closure fiaps and 32 are hinged to the top end edges of first side walls 12 and 14, respectively, along the respective hinge lines 34 and 36.
- Second closure flaps 38 and 40 are hinged to the top end edges of second sidewalls 16 and 18, respectively, along the respective hinge lines 42 and 44.
- bottom closure flaps are not shown on the containers illustrated in FIGS. 1 and 3, it is to be understood that flaps similar to those heretofore described are also hinged to the bottom end edges of the first and second sidewalls of the containers.
- An adhesive of the self-sticking type is applied to the inner surfaces of the first closure flaps 30 and 32 and to the outer surfaces of the second closure flaps 38 and 40.
- all closure flaps may be folded inwardly against the interior surfaces of the respective walls to which the flaps are hinged. As best seen in FIG. 2, the surfaces of the flaps coated with the adhesive 50 will engage those surfaces of the flaps which are not coated with adhesive.
- first closure flaps 30 and 32 may be folded inwardly against the interior surfaces of first sidewalls 12 and 14, respectively.
- the second closure flaps 38 and 40, having adhesive 50 applied to the outer surfaces thereof, may be folded outwardly against the exterior surfaces of second sidewalls 16 and 18. The orientation of the folded closure flaps is best illustrated in FIG. 4.
- each of the adhesively coated surfaces of the flaps will engage an uncoated surface of the respective wall of the container. Since the adhesive 50 has a characteristic whereby it can adhere only to a similarly coated surface, by folding the closure flaps in the manner indicated in FIG. 4, adherence of coated surfaces will be prevented.
- the containers illustrated herein when collapsed, can be stacked on top of one another without any danger that adhesively coated surfaces of two or more containers will come into contact with one another causing the containers to adhere to one another.
- closure flaps of the container were folded after the container had been erected and after the manufacturers joint, formed by securing panel 20 to the sidewall 18,
- a collapsible container formed from a unitary blank of foldable paperboard, having opposed pairs of first and second sidewalls hingedly interconnected to form a tubular structure open at the ends, self-sealing means for closing each of said open ends, comprising:
- each closure flap being folded against a side wall to which said closure flap is hinged thereby preventing engagement between coated surfaces of any two closure flaps when the container is collapsed.
- each of said first side walls is longer than each of said second side walls.
- each of said first closure flaps is folded inwardly against a first sidewall to which said first closure flap is hinged, and each of said second closure flaps is folded outwardly against a second sidewall to which said second closure flap is hinged, thereby preventing engagement between coated surfaces of any two closure flaps when the container is collapsed.
- each of said closure flaps is folded inwardly against a sidewall to which said flap is hinged thereby preventing engagement between coated surfaces of any two closure flaps when the container is collapsed.
- a collapsible container formed from a unitary blank of foldable paperboard, having opposed pairs of first and second side walls hingedly interconnected to form a tubular structure open at the ends, self-sealing means for closing each of said open ends, comprising:
- said portions having adhesive coatings on the inner surfaces thereof so arranged as to engage with and adhere to the substantially entire coated outer surfaces of said second closure flaps when the end of the container is closed;
- said adhesive coatings being of the self-adhering type which will adhere only to other similarly coated surfaces;
- each closure flap being folded against a wall to which said flap is hinged thereby preventing engagement between coated surfaces of any two closure flaps when the container is collapsed.
