  • Patent number: 5014868
    Abstract: The holding device for containers includes a receptacle member having a capacity which will accommodate a predetermined size range of containers. A selected container is held in the receptacle member by biasing members that are detachably secured to the receptacle member. The biasing members include a flap portion that resiliently bears against the container to detent the container in the receptacle. If a different container is not compatible with the biasing members, a second set of compatible biasing members can be interchanged with the first set. Since the biasing members are detachably secured to the receptacle member, the receptacle member can be formed of a plastic having one Durometer level and the biasing members can be formed of a plastic material having another Durometer level. Each Durometer level is selected to fulfill the optimum desired characteristics of the receptacle and biasing members.

  • Patent number: 5009314
    Abstract: The invention concerns assemblies or displays of plastic bottle carriers. Bottle carriers are assembled for palletization or display on an assembly plate having upstanding prongs which fit into corresponding sockets in the base of adjacent bottle carriers. The prongs and sockets are such that when the assembly is subjected to lateral pressure, for example, by palletizing machinery each prong is gripped in its socket so that the bottle carriers and the plate are an assembled unit. Preferably when no under lateral pressure, the prongs are freely slidable in the socket.

  • Patent number: 4998622
    Abstract: A plastic pail (23) and a plastic lid (22) are constructed at their rims so that the lid securely seals and catches in. Pockets to receive a carrying handle are part of a cylindrical ring (28) which surrounds the pail wall concentrically. This ring is drawn down arcuately at two diametrically opposite points (25), so that it is possible to grip and remove the lid (23) there, and a circular alignment of pails stacked nested without lids is simultaneously possible by this means.In a particular construction the recesses formed by the arcuately down-drawn parts of the ring are covered by tear-off bridges (40) which are fastened to the ring radially outside the latter.

  • Patent number: 4993582
    Abstract: A gusseted double-walled box is formed of a parison that is draped and blow molded according to the following process. A blow molding parison (10) being draped around a generally rectangular mold part (12) is spread from its extruded cylindrical shape into a generally rectangular shape (14), as it descends from an extrusion head (11). Before the open bottom (20) of the parison reaches a clamp (25) on the mold part, a jet of air is blown downward through the open bottom to draw in the parison's side and end regions (21 and 22 respectively). This reduces the size of parison (10) and helps it fit within the clamp and also forms the end regions (22) of the parison into a pair of opposed pleats (23) extending inward from the ends of the pinch-off line when clamp (25) closes. Further descending of the parison unfolds the pleats into gussets (24) extending toward corner regions (27) of mold part (12) so that the parison can drape around the mold part corners.

    Abstract: A thermoplastic case which has an interlocking bottom peripheral edging (20) with a lobe (26) on the outside surface to which a vacuum formed bottom (28) has been conformed completely enveloping the lobe creating a structural bond for fastening the two parts together. A lid edging (30) and case lid (38) are formed in the same manner completing the case. A resilient cord (46) may be added to assure the seal between the edgings and a bonding agent in the form of cement (50) or tape (52) may be employed to complete a hermetic seal for the case. Webbing (56) may optionally be added formed integrally with the edging for suspending articles within the case.
