Abstract
Abstract A container embodying improved top and bottom constructions wherein the top construction is formed from a blank including opposing top panels which are joined to each other by side panels adapted to be folded under the top panels to define a space between one of the top panels and the portions of the side panels folded thereunder. The other of the top panels is provided with a projection having locking means thereon adapted to be inserted into the space for locking engagement with stepped openings in the side panels. The bottom construction includes a bottom panel having a cut-out portion, a tongue member having locking means thereon and lateral panels which define with the cut-out portion of the bottom panel a slot adapted to receive the tongue member for locking engagement therewith. The top and bottom constructions are incapable of being opened without disfiguration of the container, thereby minimizing pilferage of the contents of the container.

Claim 1
Independent Claim
319 words
In a container construction comprising two pairs of spaced opposing side walls, a top and a bottom, the improvement comprising a top formed from a blank section comprising a pair of top panels dimensioned to share a common edge with one pair of the spaced opposing side walls said top panels defining leading edges, one of the top panels having a projection extending longitudinally along the leading edge thereof, the projection having opposing tabs extending longitudinally away from the projection adapted to be folded under the projection, a pair of side panels dimensioned to share a common edge with the other of the pair of spaced opposing side walls, with the side panels being joined to adjacent top panels, each of the side panels having fold lines extending from a point on its leading edge diagonally to divide the side panels into triangular portions, one of which is adjacent to the top panel having the projection and one of which is spaced from the top panel having the projection, with each triangular portion spaced from the top panel having an opening therein defining at least one step adapted to engage the tabs on the projection, each of said openings in the triangular portions being geometrically similar and being located on the diagonal fold lines forming those triangular portions whereby the side panels define a triangular section bounded by said openings, each of said triangular portions of the side panels being adapted to be folded under the top panels to define respective spaces between at least the other of the top panels and the triangular portions spaced from the top panel having the projection whereby the projection, with the tabs thereon folded thereunder, is adapted to be inserted into the spaces defined between the other top panel and the triangular portions of the side panels spaced from the top panel having the projection to lock the tabs on the steps.
Claim 2
Dependent Claim
319 words
In a container construction comprising two pairs of spaced opposing side walls, a top and a bottom, the improvement comprising a top formed from a blank section comprising a pair of top panels dimensioned to share a common edge with one pair of the spaced opposing side walls said top panels defining leading edges, one of the top panels having a projection extending longitudinally along the leading edge thereof, the projection having opposing tabs extending longitudinally away from the projection adapted to be folded under the projection, a pair of side panels dimensioned to share a common edge with the other of the pair of spaced opposing side walls, with the side panels being joined to adjacent top panels, each of the side panels having fold lines extending from a point on its leading edge diagonally to divide the side panels into triangular portions, one of which is adjacent to the top panel having the projection and one of which is spaced from the top panel having the projection, with each triangular portion spaced from the top panel having an opening therein defining at least one step adapted to engage the tabs on the projection, each of said openings in the triangular portions being geometrically similar and being located on the diagonal fold lines forming those triangular portions whereby the side panels define a triangular section bounded by said openings, each of said triangular portions of the side panels being adapted to be folded under the top panels to define respective spaces between at least the other of the top panels and the triangular portions spaced from the top panel having the projection whereby the projection, with the tabs thereon folded thereunder, is adapted to be inserted into the spaces defined between the other top panel and the triangular portions of the side panels spaced from the top panel having the projection to lock the tabs on the steps.
Claim 3
Dependent Claim
41 words
A container construction as defined in claim 1 wherein the openings on the triangular portions define a plurality of steps, one of which is elevated below and spaced from the others longitudinally away from the top panel having the projection thereon.
Claim 4
Dependent Claim
31 words
A container construction as defined in claim 1 wherein the projection includes at least a portion having a reduced longitudinal dimension to enable the projection to be inserted into said space.
