摘要:
A fuel tank formed by integrally forming flanges (7f, 8f) at the peripheral edge parts of bowl-like steel sheet-made upper tank half body (7) and lower tank half body (8), and overlappingly joining these flanges (7f, 8f), liquid-tight, to each other. These both flanges (7f, 8f) are fixedly caulked in a roll shape to form an annular thick wall joined part (12), and a pair of annular reinforcement ribs (7r, 8r) arranged continuously with both sides of the joined part (12) are formed on the upper and lower tank half bodies (7, 8). Thus, a sufficient strength can be imparted to the periphery of the joined part of the flanges without increasing the thickness of the steel sheet.
摘要:
A first aspect of the present invention relates to a diaphragm (2) for sealing an access opening (5) of a container body (6), the diaphragm being semi-rigid and formed with a shaped cavity (10). The present invention is particularly (but not exclusively) suitable for use with metal cans for packaging foodstuffs. A second aspect of the present invention relates to a reinforcing support (14) for locating over the diaphragm when used to seal an access opening of a container body. A third aspect of the present invention relates to a spoon (26) suitable for use with a container comprising the diaphragm.
摘要:
A can end (2) utilizes less material and has an improved internal buckle strength based on the geometric configuration of an upper and lower chuck wall (6), inner panel wall (6) and central panel (14), and having a unit depth to an outwardly concave countersink (12) of at least about 0.215 inches.
摘要:
A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by a curved panel wall to an inner wall of an annular U-shaped countersink. The countersink has a generally cylindrical outer wall and an inner width less than the radius of the panel wall. The outer wall of the countersink connects with a lower wall portion of a frustoconical chuckwall at a junction below the center panel, and an upper wall portion of the chuckwall extends to an inner wall of the crown at an angle of at least 16 DEG with the center axis. In one embodiment, the chuckwall has an intermediate generally vertical short riser portion connecting the wall portions, and the inner bottom width of the countersink is less than .040 inch.

The invention relates to a container for storing hydrous coating materials, comprising a container body (2) made of a plastic material and a base (3) which is either moulded directly onto the container body and made of the same plastic material or joined to the container body by crimping. The base consists of a metal which at least on the inside is coated with plastic. The container further comprises a top (1) which is joined to the container body by crimping and made of a metal which at least on the inside is coated with plastic. The top is either configured such that it is able to receive a press-in container lid (4a) or provided with another usual closing device (6, 4).
摘要:
A can end having a countersink bead (25), an inclined chuck wall (24) and a strong seam, resists distortion from its circular profile when subjected to thermal processing or when packaging carbonated beverages. This high hoop strength affects the manner in which the can end ultimately fails when placed under extreme abuse conditions, even if buckle pressure performance is within industry specified standards. The can end of the invention has weakened regions introduced which control the failure mode whilst maintaining specified buckle pressure performance. In one embodiment, the weakened region comprises expansion of the countersink bead to act as a trigger for local peaking, together with a groove in the chuck wall which prevents the peaking force from being concentrated at a single point which could result in leaking by the production of a pin hole.

Beim Rekonditionieren von Spundfässern (1) zu Deckelfässern wird durch einen konzentrisch zur Faßlängsachse durch den Übergangsbereich (16) zwischen Bodenscheibe (17) und Innenrand (18) des Oberbodens (7) eines Spundfasses (1) geführten Kreisschnitt (19) mittels einer Schneidrolle (20) die Bodenscheibe (17) des Oberbodens (7) von dem Faßmantel abgetrennt, und anschließend wird der untere Abschnitt (18a) des Innenrandes (18) des Oberbodens (7) mit einem Profilierwerkzeug in eine ringförmig umlaufende Innensicke des Faßhalses (5) ausgeformt. Anschließend wird auf dem Öffnungsrand (6) des Faßmantels (2) ein Spunddeckel oder ein einfacher Deckel mit einem Spannring befestigt.
