Abstract: An improved carton having, in preferred form, a break-away partition fixed between opposed side walls of the carton when the carton is initially erected into a use position from a collapsed position. The break-away partition comprises a transverse stop-rib fixed to opposite side walls at the closed end of the carton, and a cushion flap hingedly connected to one side wall only and connected in break-away fashion to the stop-rib. When an article is inserted into the open end of the erected but unfilled carton, the insertion step causes the cushion flap to break-away from the stop-rib at the carton's closed end. This allows the support rib to function as a seat for one end of the article, and this also deforms the cushion flap only as required so as to enhance the cushioning characteristic of that flap for the sides of the article, when the article is fully located in the carton.

Abstract: In a rack and tie-back clip assembly, the clips are joined in pairs by a cord and are held in a linear array on the rack. The clips can be disengaged in pairs from the rack, the mounting arrangement of the clips on the rack being such that entanglement of the cords does not occur either in storage or during removal of the clips. The rack has bars which sit within slots in the clips so as to prevent rotation of the clips while held in the rack. In a preferred arrangement, each rack holds two rows of clips, the clips lying against each other so as to provide additional stability to the assembly.

Abstract: A box folded from a box blank. The box blank has a nominally planar bottom member and four nominally planar sidewall members. The sidewall members are disposed in a cruciform array. Each of said members has an edge. Respective edges of the bottom member and sidewall members are adjacent to each other in pairs, and are laterally spaced apart from one another along a respective fold axis. A strap hinge is respective to each pair of edges, joining the members together whereby to permit rotation of the members relative to one another along the fold axis. A tooth is formed on one of the members and a recess is formed in the other of the members, the tooth and recess each having a restraint face which when engaged by the other restrains the member from lateral translational separation normal to the fold axis along the plane of one of the members. The box blank is preferably made of molded plastic and can be formed in a single piece.
