An apparatus for forming an extruded cylindrical closed-ended metal tube having a flat end wall and an integrally formed projection on the end wall includes a die having a recess formed therein, the die having a configuration which corresponds to the terminal end portion of the desired tube and including a cavity which corresponds to the desired projection. The apparatus further includes a punch which is receivable in the die, and includes an end wall having a peripheral portion which extends angularly outwardly at an angle of between approximately 10.degree. and 20.degree. relative to a plane which is perpendicular to the longitudinal axis of the die. The apparatus is operative by placing an extrudable metal disc in the recess in the die and advancing the punch into the recess with sufficient force to extrude metal from the disc into the cavity and also between the punch and the die to form the desired tube.

An improved beverage can is provided, and has a top wall, a bottom wall, and a side wall extending between and being integrally connected to the top and bottom walls. The side wall has opposing curved portions and opposing flattened or concaved portions. The flattened or concaved portions are oriented for gripping by person's thumb and fingers. One of the flattened or concaved portions is positioned below an opening in the top wall of the can such that the can is automatically oriented for drinking or pouring when grasped by a person. A circular ridge is provided adjacent the top and bottom walls of the can such that the can is rollable along a surface or track. The flattened or concaved portions also provide an advertising panel for the beverage manufacturer or distributors.

A metal container and a method of manufacturing the same as disclosed herein are provided by attaching a body formed integral with a top cover to a bottom plate formed separately. The body and bottom plate are sealably attached together with an adhesive and by a tight curl. The tight curl is formed toward the interior of the container and not exposed outside, which makes it very pleasing to the eye.

This relates to a gas and liquid tight corner structure for fibre shipping containers or drums and particularly relates to the provision of a sealing rim on the end unit which is engaged within the corner construction and is compressible so as to maintain a tightening effect on the seal of the corner structure after the corner relaxes under the influence of crimping mechanism. The sealing rim may be tubular in the case of a metal end unit or may be solid in the case of a plastic end unit and the plastic material is resiliently compressible.

A one-piece metal can body having a cylindrical side wall and an integral bottom wall. The bottom wall is disposed in a plane normal to the axis of the cylindrical side wall and is formed with one or more outwardly extending depressions which are arranged in circular configuration and are spaced radially inwardly from the peripheral edge of the bottom wall. Under unpressurized conditions the can body rests on the depressions, and when the can body is subjected to internal pressure, the bottom wall will deform outwardly in a uniform and predictable manner and the can body will remain supported by the depressions.

The side wall of a container is joined to the bottom portion thereof by a first frustoconical portion and a first semi-torroidal portion which, in turn, is joined to a second semi-torroidal portion; and, a bottom closing portion. In one embodiment the second semi-torroidal portion is joined to the bottom closing portion by a second frustoconical portion; a third semi-torroidal portion; and, a third frustoconical portion. In another embodiment the bottom closing portion is substantially flat but adapted to be domed outwardly under pressure and "cricket" inwardly when pressure is relieved.

A liquid storage tank made of panels each of which is made typically of glass reinforced plastic material and is generally rectangular and has integral flanges on all four sides. Each corner is relieved. The wall of the panel has at least one stiffening formation integral therewith and typically of dished circular configuration.Auxiliary members are used to complete the tank and occupy positions at the corners of the panels.

A dishwashing apparatus which includes a generally perforate silverware basket for holding silverware during washing, rinsing and drying operations. The basket side and end walls include vertical and diagonal intersecting ribs forming a lattice-work of perforations which promotes natural, gravitational drainage of washing fluid from the walls.

A liquid storage tank having a wall made of a plurality of metal plates having adjacent abutting edges joined together by at least vertical welded joints, at least some of the joints having an elongated tubular metal member with a surface in spanning contact with the welded joint for at least part of the joint length, a plurality of spaced apart holes in the tubular member surface, in contact with the metal plates, the joint being butt welded from one side with the tubular member in place spanning the other side of the joint, and the side edges of the tubular member surface being joined by a continuous weld to the adjacent metal plates.
摘要:
A loose metal end for forming a seamed can end closure and which includes an annular marginal seaming panel having a radiused outer rim concluding in a curled end underlying the seaming panel and provided with a peripherally interspaced array of radially extending flutes shaped to crest directionally towards the seaming panel. When double-seamed onto a can body, the fluted curled end is folded into a fluted hook end with the flutes cresting radially outward and away from the can body. As thus disposed, the flutes provide preselectively located sites which function to direct such "pinwrinkles" or "pinlips", as may result from buckling compressive forces generated in the hook end during the seaming or crimping operations, to project radially outward and away from the can body.
