CRUSH-RESISTANT BOX, BOX BLANK, AND METHOD OF MANUFACTURE
A box has a plurality of outer panels forming an outer enclosure, and a plurality of inner panels. At least some of the inner panels are disposed in a reinforcing relationship adjacent corresponding ones of the outer panels to resist crushing of the box. The box may include a lid moveable between an open position and a closed position, and which is retained in the closed position by a pattern of perforations. A blank for the box is a sheet-like member having a plurality of panels separated by a plurality of fold lines. The blank is adapted to be folded to define the outer enclosure and inner panels of the box.
This invention relates generally to containers, and more particularly to boxes for crush-sensitive products.
Products such as self-adhesive bandages are often shipped and sold in small boxes made from cardboard or other sheet-like materials. These boxes, while lightweight and inexpensive, are often subject to crushing or deformation during the necessary handling when they are packed in large quantities in larger containers, shipped to stores, and stocked on shelves. Crushed or deformed boxes are unsightly and may damage the product contained inside. It is known to make boxes crush-resistant by using thicker materials throughout, or by making the entire box a double-paneled structure. However, this introduces undesired weight and cost to the box.
BRIEF SUMMARY OF THE INVENTIONTherefore, it is an object of the invention to provide a crush-resistant box.
It is another object of the invention to provide a box having some of the panels thereof reinforced.

BRIEF DESCRIPTION OF THE DRAWINGSThe invention may be best understood by reference to the following description taken in conjunction with the accompanying drawing figures in which:
Referring to the drawings wherein identical reference numerals denote the same elements throughout the various views,
The blank 10 includes, in left to right order with reference to
Continuing left to right, the blank 10 includes outer panels 24 comprising a outer rear panel 24A with first top and bottom end flaps 26A and 28A, a first outer side panel 24A with second top and bottom end flaps 26A and 28B, an outer front panel 24C with third top and bottom end flaps 26C and 28C, and a second outer side panel 24D with fourth top and bottom end flaps 26D and 28D. A lid fold line 30 and a pattern of lid perforations 32 are disposed across portions of the outer rear panel 24A, first outer side panel 24B, outer front side panel 24C, and second outer side panel 24D to define a lid 34. It should be noted that the particular arrangement of the panels is not critical to the present invention. For example, while the illustrated blank 10 is adapted to form a box having four sides, it could also be adapted for a greater or lesser number of sides.
As shown in
The exact sequence in which the various panels are folded and secured is not of particular importance. For example, to reduce the cost of shipping, the blank 10 may be folded and secured into a flat shape without the three-dimensional volume shown in
To complete the box 36, the bottom end flaps 28A-28D are folded inward and secured together, using the securing means described above, to form a bottom end panel 38, as shown in
After the product is loaded into the box 36, the top end is closed off by folding the top end flaps 26A-26D inward and securing them together, using the securing means described above, to form a top end panel 40, as shown in
The completed and closed box 36 is shown in
When is it desired to access the product, the box 36 is broken along the lid perforations 32, and the lid tab 16 is separated at the inner perforation 18, so the lid 34 can be moved to an open position about a “live hinge” formed by the lid fold line 30, as shown in
The blank 110 may be assembled into a box 136 which is substantially identical to the box 36. The hang tab 125 initially forms a continuous part of the end flap 126C, and the box 136 may be stocked on a shelf without using the hang tag 125. When it is desired to use the hang tag 125, the tag perforations 127 are broken and the hang tag 125 is folded upwards, exposing the center hole for hanging the box 136 by a standard shelf hook. Although the end flap 126C is separated by this action, the underlying end flap 126C continues to provide a complete closure for the box 136.
The foregoing has described a crush-resistant box, and a blank and a method for making such a box. While specific embodiments of the present invention have been described, it will be apparent to those skilled in the art that various modifications thereto can be made without departing from the spirit and scope of the invention. Accordingly, the foregoing description of the preferred embodiment of the invention and the best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation, the invention being defined by the claims.
