Abstract: The invention herein relates to a method of forming a one-piece can body having a reinforced pressure-resistant can end and/or stacking bead by first forming a generally cup-shaped blank defined by a generally cylindrical body, a radius portion and an end, exerting first forces against the cup-shaped blank in a first direction to form the end into a concavely outwardly opening end defined by a central end panel, a frusto-conical wall and an annular inwardly opening channel merging with the cylindrical body, and exerting second forces against the annular channel in a second direction opposite the first direction while gripping the central end panel to reform either or both the frusto-conical wall and a part of the annular channel to selectively form one or both of an inwardly projecting outwardly opening annular bead and an outwardly projecting inwardly opening annular bead defining respective reinforcing and stacking beads, and the first and second directions defining a single reciprocal opposing path of force exertion by the first and second forces.

Abstract: A molded polyethylene salvage drum for containing hazardous wastes has a container having a solid side wall and a lid having a circular double-walled body. The container has a top portion provided on its exterior surface with male threads, an enlarged portion adjacent the threads, and a lower side wall portion adjacent the enlarged portion. An annular shoulder is formed on the container between the portion of enlarged diameter and the lower side wall. The lid has a skirt depending from the body of the lid. The interior surface of the skirt is provided with female threads mating with the male threads of the container. Castellations project upwardly from the lid body around the periphery thereof. The lid is molded so as to provide a plurality of kiss-off sections, in which the two walls of the body are molded together during rotational molding of the lid. The skirt of the lid terminates at its lower end in an outwardly extending lip with the outer diameter of the lip equal to the outer diameter of the enlarged diameter portion of the container. A gasket is provided in a circular recess in the lid for sealing engagement with the top edge of the container.

Abstract: A container (30d) of polyethylene terephthalate or similar thermoplastic material has a container body (32d), a mouth portion (37d) and a central bottom part (34d). The central bottom part consists of chiefly amorphous and/or thermocrystallized material and forms a bulge directed towards the interior of the container. A ring-shaped or band-shaped standing surface (36d) is arranged adjacent the transition of the bottom part into the container wall (32d). Adjacent to the standing surface the container has a circumferential area of material (35d) which by stretching and/or reshaping has undergone flow and by heating has acquired built-in stresses which tend to contract it. The surrounding circumferential area of material prevents the inward bulge of the central bottom part from straightening out and/or turning inside out when the pressure in the container is increased and/or when the temperature of the container material is raised.

Abstract: A drawn and ironed can body has a cylindrical side wall and an integral end wall which closes one end of the side wall. The end wall includes a rim that generally curves inwardly from the side wall and a domed central section which closes the area circumscribed by the rim, all such that the rim forms the lowest portion of the can body. The rim is configured such that when the can body is subjected to elevated internal pressures, the rim deforms in a controlled manner, and this deformation causes the domed wall to move axially away from the opposite end of the can body without buckling, thereby increasing the volume of the can body.

Abstract: A generally dome-shaped end closure for a receptacle, such as, the bottom end wall of a beverage container is roll-formed in a closely coordinated sequence of steps wherein the receptacle is fixed in position so that the external surface of the end wall to be formed is disposed in facing relation to a yieldable support, and rotatable bearing surfaces are simultaneously advanced into engagement with the end wall while being continuously rotated about a common axis whereby to form one or more annular ribs in the end wall while forcing the end wall to assume a generally convex or dome-shaped configuration as it is expanded outwardly against the yieldable support. A roll-forming apparatus for carrying out the method of the present invention permits a succession of end walls to be roll-formed on a revolving turret which carries a plurality of roller assemblies, each roller assembly defining the rotatable bearing surfaces which are rotated by a spindle drive, the spindle drive being axially advanced by a cam member as it is rotated to cause the associated roller assembly to advance axially through the interior of each receptacle for the roll-forming operation followed by retraction away from the receptacle whereupon the yieldable support is operative to release the can from its fixed position for unloading into a separate stacking area.

Abstract: Plastic containers having improved physical properties are prepared from a composite billet having an outer peripheral area composed of a thermoplastic resin and an inner central core portion composed of the thermoplastic resin modified with a material which imparts improved physical properties such as reduced gas permeability or increased stiffness or rigidity to the resin. The composite billet is molded into a container wherein the billet core is formed into the sidewalls and bottom of the container and the peripheral portion is formed into a flexible thermoplastic flange surrounding the open end of the container which can be doubled seamed to a metal end closure without fracture.

Abstract: Method for making containers having enhanced emptying capability include a filling/emptying opening disposed closely adjacent the container sidewall and extending through integral top closure structure. The container sidewall has a portion contiguous with the filling/emptying opening which extends therefrom without radial step discontinuity, thus avoiding well formation adjacent the opening. A parison is stretched unidirectionally and transversely against restraint by a blow pin to avoid buildup of material in the sidewall portion contiguous with the filling/emptying opening and the stretched parison is blow molded to form the container.

Abstract: An industrial sized drum that may be blow-molded of polyethylene is constructed with integrally formed rolling hoops, a domed top having an interrupted chime of generally arcuate cross-section undercut on its interior side, necks extending upward from a pair of diametrically opposed bungholes, symmetrically disposed dimples in the drum top adjacent these necks to maintain ovalization. The necks are formed to facilitate crimp-type securement of closures by crimp-type techniques. The drum bottom is formed with a chime and a sump pad aligned with one of the bungholes.
