Description
Background of the Invention
This invention relates generally to wardrobe or storage containers, and more particularly, to novel access door means for providing access into the interior of the containers, said means including a built-in access door frame.
Wardrobe or storage containers formed from integral paperboard blanks are well known as economical, lightweight and durable structures. The upper end of the container body is generally designed to support a conventional hanger bar spanned between opposite walls of the container body so that articles of clothing on clothes hangers can be supported from the span of the hanger bar in the interior of the container body.
The herein invention achieves its objectives utilizing special cuts in the body for access into the container. Advantageous economies in fabrication of the container are realized along with a more desirable, more efficient, partial or full access door in an end or side wall having a built-in frame, jamb and attached top end flap which completes the closure of the top of the container in cooperation with another top end flap.
Summary of the Invention
A wardrobe container formed from a one-piece pre-scored foldable blank which includes at least two side walls, two end walls, a bottom wall and two top end flaps connected together. One of the side or end walls includes an access door or panel hingedly connected to the said wall or to an adjacent wall. The access door is formed from a portion of the said wall and the container includes a built-in jamb and door stop to form a built-in frame for the door.

Description of the Preferred Embodiment
Referring to FIG. 1, there is illustrated a wardrobe or storage container designated generally by the reference character 10 embodying one form of access door means. The container 10 can be erected from integral blanks die-cut from sheeting of paperboard, either corrugated or otherwise, or from other like material by conventional automatic machinery. The container 10 includes two side walls 12 and 14, two end walls 16 and 18 and a bottom wall 20 which are conjoined along lines of fold. The side wall 14 has an extension providing a hinged panel 22 which abutts a portion of end wall 16 and which may be assembled thereto with adhesive or other suitable fastening means.
A first pair of end flaps 24 and 26 is hingedly connected to the upper edges of side walls 12 and 14 respectively. Each of the end flaps 24 and 26 may include hanger bar support assemblage or means 28 and 30, partially severable therefrom, as seen in FIG. 2, which are foldable to a position displaced from the plane of the end flaps, leaving the cut outs 32 and 34 seen in FIG. 1. Said means 28 and 30 each are shown engaged against an associated side wall along the exterior surface of the side wall.
A second pair of top end flaps 36 and 38 is provided, adapted to be folded over the first pair of end flaps 24 and 26. The top end flap 36 is hingedly connected to a first access door or panel 40. The access panel 40 is hingedly connected to the side wall 12 and terminates above the bottom portion of the end wall 16 and has a width less than the end wall 16 to leave a narrow end wall portion or jamb 42. The exposed portion of the panel 22 beyond the jamb 42 forms a door stop for the access panel 40. The jamb 42 and door stop form a built-in frame for the access panel 40.
A hanger bar 44 of conventional design may be fitted into the container 10. Further details of the container 10, the hanger bar 44 and support thereof are shown and described in said copending application Serial No. 807,383 which is incorporated herein by reference.
The wardrobe container 10 preferably is formed from a one-piece blank 48 which is best illustrated in FIG. 2. The bottom wall 20 of the container 10 is formed from four bottom flaps 50, 52, 54 and 56 in a conventional manner. The bottom flaps, top flaps, the side walls and end walls, as well as the side flap 22, are connected along lines of fold 58. The access panel 40 is formed from the end wall 16 along a cut or perforation line 60. The cutout portions 28 and 30 are formed from their respective end flaps 24 and 26 along respective cut or perforation lines 62 and 64. The lines 60, 62 and 64 preferably are not completely cut so that the access panel 40 and the cutout portions 28 and 30 will stay in place until the container 10 is to be assembled.
The portions 28 and 30 have openings 66 and 68, in the panel sections 61 and 63, to which the hanger bar parts 46 are extendable. The access panel 40 may be opened along the perforation line 60 by grasping the top flap 36 and a lower cutout panel portion 71.
FIG. 3 illustrates a container 10B having a modified access panel 40B. Here, the panel or door 40B has an extension flap 41 extending from a line of fold 43. The wall portion 16B has an L-shaped extension flap 16C extending therefrom and secured to the inside surface of the side wall 14B. The flap 16C forms the jamb for the panel 40B when the panel is closed. The extension flap 41 is sized to engage against the extension flap or jamb 16C in mating edge engagement therewith and abutting an exposed portion 45 of the side wall 14B on the interior thereof. The portion 45 forms the door stop for the flap 41 of the panel 40B which may be adhesively secured thereto.
FIG. 4 shows the embodiment of FIG. 3, but with the extension flap or jamb 16C secured to the exterior of the wall 14B. The extension flap 41 will also abut an exterior exposed portion or door jamb 47 of the wall 14B.
FIG. 5 illustrates a container 10C having a multipart embodiment of access panel having two portions 40C and 40D. The wall portion 16D has an extension or jamb 16E which is cut off and secured to the portion 40D. The exposed portion 49 of the exterior of the portion 40D forms the door jamb for the portion 40C. The interior edge of the portion 40C abuts an exposed corner 51 of the wall portion 14C and may be adhesively secured to the corner 51 and the door jamb 49. The portions may of course be reversed in their operation.
FIG. 6 illustrates a wardrobe container 10D having an access panel 40E. The panel 40E is hingedly secured to the end wall portion 16F along a horizontal line of fold 66. An extension flap 16G forms a jamb for the panel 40E and is secured to panel 22. The exposed part of the panel 22 forms the door stop for the panel 40E.
FIG. 7 shows a container 10E including a modified embodiment of access panel 40F from that shown in FIG. 6. The panel 40F is hingedly secured to the end wall portion 16H along a diagonal line of fold 68. The extension flap 16I forms a jamb for the panel 40F in a like manner as the extension 16G.
It is to be understood that the invention contemplates implementation thereof in connection with other than the end wall 16. The hanger bar support means may be other than that shown or may be omitted if desired. The respective sizes illustrated are also illustrated as an example, and many other combinations of sizes of the walls and access panels and the corresponding assembled carton are possible within the scope of the invention.
