Abstract

A storage and transportation box of the type having a container body with handhold apertures includes an improved cover having side skirts which partially overlap the handhold apertures and carry locking tabs selectively receivable within the handhold apertures to lock and secure the cover in place upon the container body.

Claims

1. In a storage and transportation box of the type having a container body with side walls extending upwardly from a closed bottom to an open top and at least one handhold aperture located in a side wall, adjacent to and spaced downwardly from the open top, the handhold aperture having laterally spaced apart opposite end boundaries defining opposite ends and laterally extending upper and lower boundaries, and a cover for placement over the open top of the container body so as to close the top, the cover including a top wall and depending skirts integral with the top wall for juxtaposition with corresponding side walls of the container body in a generally telescoping relationship, the skirts having lowermost edges spaced downwardly from the top wall, the improvement wherein:

the lowermost edge of at least the skirt corresponding to the side wall with the handhold aperture is spaced downwardly relative to the downward spacing of the handhold aperture to locate said lowermost edge in a position extending laterally across the handhold aperture, between the upper and lower boundaries thereof, a slit in the skirt extending upwardly from the lowermost edge toward the top wall adjacent each end of the handhold aperture, and a fold-line extending laterally between the slits, adacent the uppermost boundary of the handhold aperture, such that the slits and the fold-line defined a locking tab receivable within the handhold aperture, upon folding of the locking tab inwardly along the fold-line and through the handhold aperture, to secure the cover against upward movement relative to the container body; and

the cover is erected from a blank of foldable material, such as corrugated paper board, the blank including a top section having laterally space apart opposite sides and longitudinally spaced apart opposite ends for forming the top wall, side sections at each side of the top section for forming opposite side skirts, and end sections at each of the opposite ends for forming opposite end skirts, the end sections each having two skirt portions and a laterally extending lowermost edge fold-line located between the two skirt portions and extending between the opposite sides, said laterally extending lowermost edge fold-line defining the lowermoset edge of the end skirt when the end skirt portions are folded into juxtaposition with one another along the lowermost edge fold-line, said slits extending transverse to the lowermost edge fold-line in opposite directions away from the lowermost edge fold-line such that the locking tab includes a locking tab portion in each of the end skirt portions, the locking tab portions being folded into juxtaposition with one another when the end skirt portions are folded into juxtaposition with one another.

2. The invention of claim 1 wherein the slits in each end skirt portion converge toward one another in the direction away from the lowermost edge fold-line such that upon erection of the cover the locking tab is provided with a dove-tail configuration.

3. The invention of claim 1 including end skirt flaps integral with each side skirt section at the longitudinal ends of the side skirt sections, the end skirt flaps having terminal end edges and being foldable for extending between the end skirt portions of a corresponding end skirt when said end skirt portions are folded along said lowermost edge fold-line into juxtaposition with one another such that the end skirt flaps confront one another at the terminal end edges thereof, one of said end skirt flaps being longer than the other of said end skirt flaps so that the terminal end edges confront one another at a location offset laterally relative to the locking tab.

4. The invention of claim 3 wherein the end skirt flaps of one of said opposite end skirts confront one another at a first location offset laterally in a first lateral direction relative to the locking tab and the end skirt flaps of the other of said opposite end skirts confront one another at a second location offset lateraly in a second lateral direction relative to the locking tab, the second lateral direction being opposite to the first lateral direction.

5. The invention of claim 3 the slits in each end skirt portion converge toward one another in the direction away from the lowermost edge fold-line such that upon erection of the cover the locking tab is provided with a dove-tail configuration.
