Description

BACKGROUND OF THE INVENTION

It is known in the packaging art to provide packages of candy or other items in containers, for display to customers in stores. It is also known that such containers can be shipped to the locations of display in knockdown form; i.e., flattened but otherwise being glued, stapled or otherwise secured together, such that they are already substantially preassembled, it generally only being necessary to open the sides and or ends of the containers and to affix the container bottom wall into its assembled condition, such that smaller packages, bags, or the like of candies or other products can be placed into the assembled display container, for ready display.

It is also known in the packaging art that it is sometimes desirable to be able to stack a plurality of such display containers, one on top of the other, so that such containers as may be stacked above the bottom-most container are amply supported and so that a stack of a number of such containers, when filled with packages for display, will not collapse.

It is also known in the art that such containers can be made from blanks that are provided with pre-cut cut lines and pre-scored or pre-formed fold lines.

SUMMARY OF INVENTION

The present is directed to providing a stackable display container for receiving and displaying products therein, wherein upstanding walls of the container are provided with associated spacer panels that together define stacking supports for the container, to support containers carried thereabove, wherein each stacking support is thicker than the combined thickness of an upstanding container wall and its associated spacer panel.

Accordingly, it is a primary object of this invention to provide a stackable display container in which spacer panels are used in connection with upstanding walls, to provide increased thickness of upstanding walls and their associated spacer panels, for stable stacking support for other stacking containers disposed thereon.

It is another object of this invention to provide a novel container preassembly for accomplishing the object set forth above.

It is a further object of this invention to provide a novel container blank for accomplishing the objects set forth above.

DETAILED DESCRIPTIONS OF THE PREFERRED EMBODIMENTS

Referring now to the drawings in detail, reference is first made to FIG. 1, wherein a stackable display container is shown, generally designated by the numeral 10, having an upstanding front wall 11, an upstanding back wall 12 and upstanding right and left end walls 13 and 14, respectively.

The front wall 11 is connected to the right and left end walls 13 and 14 along fold lines 15 and 16, respectively and forms corners therewith. Similarly, the back wall 12 is connected to the right and left end walls 13 and 14, respectively, along fold lines 17 and 18, forming corners therewith as shown.

The container 10 is thus formed in a rectangular configuration, with the front and back walls 11 and 12 forming a pair of opposing walls, and with the right and left walls 13 and 14 also forming a pair of opposing walls.

A bottom wall 20 substantially closes over the rectangular space defined by the walls 11-14, at the lower ends of walls 11-14.

A pair of spacer panels 21 and 22 are shown, also being upstanding, and extending in each case from the front wall 11, to the back wall 12 along fold lines 23-26, as shown. The spacer panels 21 and 22 are disposed generally parallel to their respectively associated upstanding right and left end walls 13, 14, spaced inboard thereof, in each case, as shown, to leave spaces 27, 28, between the spacer panels 21, 22 and their respectively associated end walls 13, 14.

Thus, with each end wall 13 and 14 being of corrugated cardboard construction, as shown, and of a thickness T1, and with each spacer panel likewise being of corrugated cardboard construction and of a thickness T2, the dimension “D” between the outer surface of each end wall and the inner surface of its associated spacer panel, is greater than the combined thicknesses of a given end wall and its associated spacer panel. Thus, “D” is greater than T1 plus T2, as shown.

The bottom wall 20 is comprised of a plurality of bottom wall panels, which will be discussed hereinafter.

In the embodiment shown in FIG. 1, all of the walls are constructed of corrugated cardboard, although, such is exemplary only, in that the various walls, the panels that comprise them, any tabs on various panels or the like, may all be constructed of other materials that will meet that criteria set forth in the claims.

The back wall 12 is comprised of two different back wall portions 30 and 31, secured together as a single wall 12, via an adhesive coated tab 32 extending from back wall portion 30, and being adhesively secured behind back wall portion 31, as shown.

An optional container divider 33 is shown, in phantom because it is optional, extending between and foldably connected to the front wall 11 and the back wall 12, as shown.

With reference now to FIG. 2, it will be seen that a plurality of stackable display containers are shown, stacked one upon the other, and that the stacking support provided at the right and left ends of the containers 10, by means of the spacer panels 21, 22, being disposed inboard of, and parallel to their respectively associated upstanding end walls 13, 14, provide a stacking support width “D”, at each of the right and left ends of the containers 10, for enabling one to stack multiple containers, one upon the other, with stability and improved stacking strength.

In the containers as shown in FIGS. 1 and 2, it will be seen that there are provided access openings 34, 35, defined by U-shaped cut-outs in the front wall 11 of the container 10, for ready access to packages that are to be displayed in the container 10. It will also be seen that the access openings 34, 35 communicate with the open upper end of the container 10, which is free of any top wall or panel covering the same, also for ready access to containers in a stack such as shown in FIG. 2; especially to the uppermost container 10 in that stack.

With reference now to FIG. 3, it will be seen that the front wall 11 of the container 10 is comprised of outer and inner panels 40 and 41, connected together along a fold line 42. Similarly, rear panel portion 30 of rear wall 12 is comprised of outer and inner wall panels 43 and 44, respectively, connected together along a fold line 45.
