Abstract: Two-piece metal aerosol container (20) and method of manufacture are provided in accordance with the present invention. A rolled and longitudinally welded cylindrical tube (15) forms the container body (26), including a cylindrical sidewall and reduced diameter shoulder (109) and neck portions (110) (formed by a sequential necking process), while a separate metal base component (104) is attached via a crimped seam (106). The open-top end of the container neck portion is curled to receive a manually actuatable dispensing valve assembly. The container is resistant to internal pressures in excess of 311 psi (2150 kPa) and offers increased strength and pressure resistance (compared to a three piece rolled metal aerosol container), while being easy to manufacture and low in cost.

Abstract: A beverage can is formed to enable easy compression thereof for a disposal, and has a cylindrical body, a plurality of oblique grooves formed on the cylindrical body at uniform intervals, a bottom and a top, in which, as the bottom and the top of the can are pressed in opposite directions, the cylindrical body is subject to torsion and crushed in the guidance of the oblique grooves. By the structure of the beverage can that is formed to be compressed by torsion in the guidance of the oblique grooves, efficiency of transportation and storage of the used cans for recycling improves, while the recycling process of the used cans becomes simpler and more economical due to the reduction of recycling process and omission of the use of compressing machines.

Abstract: Process for producing a shell which extends about a longitudinal axis, as a component for a gastight packaging, for example a food can, which shell, in the vicinity of an end, as seen in cross section, has a first contour which comprises N (N >/= 3) inwardly concave rim contour sections, between which there are N substantially straight rim contour sections, and which shell, for the area between the ends, as seen in cross section, has a second contour which comprises N straight shell contour sections, which correspond to the straight rim contour sections and, as seen in the peripheral direction, adjoin a neighbouring straight shell contour section via, in succession, an inwardly concave shell contour section, a corner panel contour section and an inwardly concave shell contour section. The process is characterized by the conditions which the applied stretching and the ratio of the applied stretching in the first and second contours have to satisfy in order to produce a shell from material which is as thin as possible without the material fracturing or, in particular in the transition zone from the rounded cross section to the flattened, rounded cross section, without the material wrinkling, becoming dented or being pulled convex or concave in some other way. The present invention also relates to the production of a necked metal packaging container, characterized in that the neck shape is imparted to a starting shell before the N-cornered shape is imparted. The invention also provides an expansion tool which is suitable for carrying out the process.

Abstract: A die (104) for forming a blank (14) into a container body (26) having an open end provides an annular undulated shaping surface (106) of substantially uniform radius. The container body (26) is formed by moving the blank through the shaping die (104), with the result that the undulations (106) laterally redistribute metal in the sidewall of the container body, as well as iron the sidewall during the forming process. The die enables the use of a blank (14) of noncircular geometric shape, such as a hexagon, by redistributing metal from the points of the hexagon to the area of the flats in order to produce an end product without excessive earing.

Abstract: A method of manufacturing a metallic can body (24) that is shaped distinctively in order to enhance its visual presentation to consumers includes, in one embodiment, steps of providing a can body blank (10) that has a sidewall that is of a substantially constant diameter; providing a mold unit (38) that has at least one mold wall (46) that defines a mold cavity conforming a desired final shape of the can body (24); positioning the can body blank (10) within the mold cavity (46); and supplying a pressurized fluid into the mold cavity so that the can body blank (10) is forced by pressure against the mold wall (46), causing the can body blank (10) to assume the desired final shape of the can body (24). Axial compression is preferably applied to the can body blank in order to reduce internal stresses during molding of the container. A second embodiment includes steps of radially deforming the can body blank in selected areas by selected amounts to achieve an intermediate can body that is radially modified, but is still symmetrical about its axis; and superimposing a preselected pattern of mechanical deformations that have an axial component onto the intermediate can body. Related apparatus and processes are also disclosed.

Abstract: Bottles (100) with inwardly curled upper portions at the bottle opening and methods and tooling for producing such bottles. The inwardly curled upper portions impart compressive stresses into the bottle material and can reduce a likelihood of material splitting because the upper portion may not be stretched to a larger outer diameter as with outwardly curled upper portions. The inwardly curled upper portions may be formed using rollers (500) with an entry radius (504) positioned near an outside diameter of the bottle opening. The inward curl is formed as the bottle material enters the rollers near an entry face (502) of the rollers, transitions through a work face (506) of the rollers, and exits the roller at an exit face (510) of the rollers. The resulting inward curl meets the edge of the bottle material near the inner surface of the bottle.
