摘要:
The present invention relates to a method for making a shaped metal container (1), comprising a container middle section (3-5) having at least one middle section diameter (Dm i ), which container middle section (3-5) is connected at one end to a container bottom section (6) having at least one bottom section diameter (Db), and at the other end connected to a container top section (10) having a container opening (14), and having at least one top section diameter (Dt), comprising the steps of: i) providing a container preform (25) having a cylindrical body (26) with a diameter (Dc); ii) inwardly shaping by necking at least a section (28) of the cylindrical body (26); and iii) outwardly shaping at least a section of the cylindrical bodyb (26), wherein at least a section to be inwardly or outwardly shaped is annealed, such that at least one of the middle section diameter( Dmi), the bottom section diameter (Db), and the top section diameter (Dt) is greater than, and at least one of the middle section diameter (Dmi), the bottom section diameter (Db) and the top section diameter (Dt), is smaller than the cylinder diameter (Dc) of the container perform (26), and to the shaped metal container (1).

To provide a variant-can by performing a diameter-reduction process up to the vicinity of a bottom part on a trunk part of a can-body made of metal. A diameter-reduction apparatus for can-trunk for performing a diameter-reduction process on a trunk part of a can-body having a closed-end cylindrical shape with an open end, including: a can-body holder holding a bottom part of the can-body, which is provided with: a base pad abutting on the bottom part of the can-boy; and a first clamping-ring having substantially a cylindrical shape which clamps an outer circumference surface of a trunk part of the can-body at the bottom side and which moves back and forth relative to the base pad along a can-axis direction; a die unit for diameter-reduction provided with a die for a diameter-reduction process of the trunk part by moving back and forth with respect to the can-body holder along the can-axis direction; and a first clamping-ring moving device moving the first clamping-ring backward along the can-axis direction along with an advance of the die.

The invention relates to a container (1) having a container space (2) and a dispensing neck (4) having a dispensing opening (3) and comprising a substantially round cross-section and on which a fastening device (7) is provided for fastening a closure cap (10) over the dispensing opening (3), wherein said container comprises an outer sleeve (6) that is rigidly disposed on the dispensing neck (4). The fastening device (7) is formed on the outer sleeve (6). The outer sleeve (6) is placed at least partially over the dispensing neck (4). The outer circumference of the dispensing neck (4) is pressed onto an inner circumferential surface of the outer sleeve (6).

A machine arrangement including a vacuum transfer turret assembly configured to releasably hold one or more containers and to rotate the one or more containers about the turret assembly when the one or more containers are held by the turret assembly. The turret assembly includes a shaft assembly, a starwheel assembly, and a vacuum assembly. The starwheel assembly is releasably secured to the shaft assembly. The turret assembly is adapted to, when the starwheel assembly is secured to the shaft assembly, rotate the shaft assembly to rotate the starwheel assembly relative to the vacuum assembly and when the starwheel assembly is rotatably released from the shaft assembly, enable movement of the starwheel assembly and the vacuum manifold along the shaft assembly towards and away from the vacuum assembly.

The invention relates to a method and apparatus for making can (61), such as a paint can, comprising the steps of: i. providing a cylindrical body (2,36,51,65); ii. arranging piston means (14,25,44,74) in a first opening (20,60,75) of the cylindrical body for defining the diameter of the opening; iii. curling a free end (8,66) of the first opening (20,60,75) radially outwardly and axially along the cylindrical body (2,36,51,65) thereby forming a curl (47,48,57,68,70,79), such that the defined diameter of the first opening (20,60,75) is substantially circumferentially, dimensionally stable, and to the can (61) and can body (63) made.
摘要:
A die necking method and apparatus for producing a smooth tapered wall between the container side wall and a reduced diameter neck includes a plurality of rotatable necking turrets that each have a plurality of identical necking substations each having a necking die. The necking dies in the respective turrets have an internal configuration to produce a necked-in portion on the container which has a first arcuate segment integral with the container side wall and a second arcuate segment integral with the reduced diameter neck. The necking substations also have a floating form control element that engages the inner surface of the container to control the portion of the container to be necked. The necked-in portion is reformed in each succeeding turret by dies to produce a smooth tapered wall between the arcuate segments.
