Abstract: A locking tongue has a base part, a webbing slot in the base part and a locking cam. The locking cam is movable between a rest position and a clamping position. A biasing means biases the locking cam towards the rest position. The locking cam can assume the rest position in which the belt webbing can pass freely through the webbing slot, a clamping position in which the locking cam presses the belt webbing against the clamping edge of the webbing slot, the biasing means being able to return the locking cam from the clamping position into the rest position, and a locking position in which the locking cam locks the belt webbing in the webbing slot, the biasing means not being able to return the locking cam from the locking position towards the rest position.

Abstract: An apparatus (10) is provided for erecting boxes from blanks (11) having sides panels (13) with three score lines (20, 22 and 24). The apparatus has a base plate (40), two side folding mechanisms (44) and two end folding mechanisms (45). The side folding mechanisms have a proximal plate (51) pivotally mounted to the base plate, an intermediary plate (53) pivotally mounted to the proximal plate, and a distal plate (55) pivotally mounted to the intermediary plate. Linkage (68) coupled to a handle (76) actuates the movement of the proximal, intermediary and distal plates.

Abstract: A decorative tray or tray cover is formed from a scored paperboard blank having main, side and end panels and base flaps arranged for simultaneous manipulation with an unscored paper blank having a decorative outer surface and being disposed in coincidence with the paperboard blank and with its inner surface in face contacting relation therewith to provide tray or tray cover which is attractive in appearance and which requires no adhesive of any kind.

Abstract: Corner structure for an open tray or tray cover is formed from a unitary blank comprising a rectangular main panel, a first pair of outer side panels foldably joined to a first pair of opposite side edges of the main panel, a first pair of inner side panels foldably joined respectively to the edges of the first pair of outer side panels which are remote from the main panel, a first pair of base flaps foldably joined respectively to the edges of the first pair of inner side panels which are remote from the first pair of outer side panels, a second pair of outer side panels foldably joined respectively to a second pair of opposite side edges of the main panel, a pair of inner side panels foldably joined respectively to the edges of the second pair of outer side panels which are remote from the main panel, a second pair of base flaps foldably joined respectively to the edges of the second pair of inner side panels which are remote from the second pair of outer side panels, a collapsible web at each corner of the
