The container comprises a peripheral side wall (10), whose upper peripheral edge (10c) defines a retention hook (11) with a profile in the form of an inverted U, having an inner side leg (11a), an arched base leg (11b) and an outer lateral leg (11c). An upper end wall (20) of the container comprises a median panel (21) and a peripheral upper skirt (22) having an end edge (22c) defining a closure hook (23) with a profile in the form of an inverted U, having an inner side portion (23a), an arched base portion (23b), and an outer side portion (23c) which incorporates an upwardly projecting end flange (23d). The closure hook (23) is fitted onto the retention hook (11) and radially inwardly deformed, compressing an elastic sealing element (40) between the two hooks and maintaining the end flange (23d) projecting upwardly to the interior of the retention hook (11).
摘要:
The present invention relates to the manufacture of two-piece cans, comprising body and cover, with the most varied shapes of bodies, enabling expansion by means of various processes through the specific tooling, that expands the format desired to be obtained. The body of the can (1) is transported (2) for equipment (3) and, via a transport system with endless screw (4), which rotates synchronously, by means of gears (5), with the star input (6) via cardan shaft (14) and angled gearbox (15). By means of gears (8), the can body (1) is transferred to the expansion station (7), input by the star (6), where the expansion takes place the can body in two parts (1). Using this same type of synchronism, by means of gears (10 and 11), the can body is transferred expanded, the station (7) for a conveyor belt exit (13) by means of a star outlet (9).
摘要:
A container including a metal sidewall is provided. The metal sidewall includes a first end; a second end; a center portion having a principal width; a first feature positioned between the center portion and the first end, the first feature extending from the sidewall such that the maximum width of the sidewall at the first feature is greater than the principal width; and a second feature positioned between the center portion and the second end, the second feature extending from the sidewall such that the maximum width of the sidewall at the second feature is greater than the principal width. The container further includes a first bead located in the center portion of the sidewall; and a second bead located in the center portion of the sidewall.

A temperature changing container includes a plurality of walls joined to form an enclosure which seals contents of the enclosure within the walls. One of the walls includes a depression extending into the enclosure. Upon activation, chemicals at least partially disposed within the depression change temperature.
摘要:
In at least one embodiment, for producing segments of tubular jackets, a strip-shaped sheet material is continuously reshaped transverse to the strip axis into a closed form and following the welding of a longitudinal seam, jacket sections are cut off the jacket strip. In at least one embodiment, a support edge is provided on the inside of the continuously formed jacket strip for the cutting operation, essentially in the form of a closed circle and extending in a normal plane to the longitudinal axis of the jacket strip, which fits directly against the inside of the jacket strip and cooperates with at least one cutting tool. The cutting tool is pivoted into the cutting position during the cutting operation along the support edge, so that a cutting region rotates once around the longitudinal axis. A section of the jacket strip is cut off, wherein during the cutting operation, the support edge and the at least one cutting tool are advanced along with the jacket strip. Following the cutting operation, the at least one cutting tool is moved to a non-contacting position relative to the support edge and together with the support edge is moved counter to the movement of the jacket strip and back to the starting position occupied prior to the cutting operation.

A method is provided for forming an end closure for a surrounding sidewall of a container, such as an aluminum can. The method includes forming a central body panel oriented transversely to the central axis of the can and forming an outer surrounding margin portion joined to the sidewall such that the margin portion has a support section oriented longitudinally relative to the sidewall. A portion of the margin is corrugated to provide a rib structure having longitudinally extending first rib components located on the support section. This method can be accomplished during the ironing and doming of a can.

A process for manufacturing a can with a polygonal cross-section and a can with a polygonal cross-section, the process comprising the steps of milling the cylindrical lateral wall of a tubular body (10), providing said wall with a plurality of circumferential ribs (20) which are continuous and axially spaced from each other and defined by a certain degree of radial plastic deformation of the respective circumferential region of the cylindrical lateral wall of the tubular body (10); expanding the formed tubular body (10), deforming it, in order to define longitudinal edges (12) in whose region the circumferential ribs (20) are eliminated; and double-seaming a bottom and an upper wall of the can to the tubular body (10). This process defines a can having any polygonal cross-section and circumferential ribs (20) on the lateral wall thereof, between the longitudinal edges (12).
