Abstract:
There is provided a method of forming a shaped metal closure from a tubular blank (10) having a closed end and an open end, comprising the steps of: i. at least one expansion step at a point axially displaced from the open end; and ii. at least one reduction step at a point axially displaced from the open end.
Abstract:
A plastic resealable closure includes a base plate affixed to a can, a middle plate having a plug, and a top plate having a support ring. The support ring expands or supports the plug to enhance sealing. The top plate includes prongs that are insertable into recesses on the base plate to enhance closing. The closure is applied without heating of the tool or the closure.
Abstract:
A container for food which is closed by a peelable membrane (2) at one end and a sanitary end (4) at the opposite end. The container has a ring (1) to which the membrane is fixed, the ring and sanitary end being formed from the same sheet metal. In order to make this possible, the container body (3) flares outwardly at the end to which the ring is fixed and is necked at the opposite end. Dimensions are selected so that the resultant container is not only stable but also readily handled during manufacture, filling and on supermarket shelves.
Abstract:
This invention relates to a self-heating or self-cooling container (1), which uses an exothermic or endothermic reaction to provide or remove heat from the contents of the container. The chemical reaction includes a fluid consistuent (either as a reagent or solvent), held in a reservoir (6), which is added to another reagent in the reaction chamber (5) to initiate the reaction. The container (1) according to the invention proposes a means (8, 91) to control the volume of this fluid constituent added to the reaction chamber (5) depending on the ambient temperature of the container.
Abstract:
There is disclosed herein a can end (10) for a can for pressurized contents, the can end being configured to be joined by a peripheral annular joining portion (24,26) to one axial end of a can body of the can and having an outer side arranged to face outwardly from the can and an inner side arranged to face inwardly into the can, the can end comprising: a central panel (18); a panel wall (20) annularly surrounding the central panel and extending axially inwardly and radially outwardly from the central panel; an annular chuck wall structure (12, 14, 50) extending radially- and axially-inwardly from the joining portion; and an annular bead (16) which is connected between a radially outer edge (38) of the panel wall and a radially inner edge (50e) of the chuck wall structure and which is concave with respect to the outer side of the can end and extends at least partially radially outwardly with respect to the radially inner edge of the chuck wall structure, wherein wall portions adjacent inner and outer ends of the concave annular bead (16) form a bead mouth (m) that is open towards the outer side of the can end.
Abstract:
A double walled container comprising an inner container having a sidewall (52) and a base (54) connected thereto, and an outer container (1) having a sidewall (2) and a base (4) connected thereto and arranged to accommodate the inner container, whilst defining a gap therebetween. The sidewall (2) of the outer container has a securement region, which is formed to have a smaller diameter compared with the diameter of the sidewall (52) of the inner container. The inner container may take the form of a filled beverage can (90), which is sealed by an end (70) seamed thereto and is subsequently inserted into a larger outer can during the final stage of production.
Abstract:
A sheet metal lid (1) for fixing to a container body, the lid (1) comprising a centre panel (2) surrounded by a seaming portion (4), which is adapted to be joined to the periphery of the container body after it has been filled with a product. The centre panel (2) defines an aperture (7) through which the product may be dispensed from the container. The aperture (7) is designed to accommodate a separate closure and the cut edge of the aperture (7) is curled to protect a user from cuts and to provide an aperture curl, which engages with the separate closure provide a fluid tight seal. The closure moves relative to the centre panel between a closed position, in which the aperture and the closure together form a fluid-tight seal, and an open position, in which the seal is broken and the closure moves relative to the centre panel to open at least part of the aperture.
Abstract:
A closure assembly comprising a two-part closure having a metal panel or disc (2) and a ring (3), and a container such as a glass jar (20). The ring (3) is substantially cylindrical with an axially upwardly extending sidewall and has a radially inwardly extending lower edge. The jar (20) terminates in a radially outwardly extending beaded rim (16) and the disc (2) has a curled circumference (8) such that this curl (8) co-operates with the beaded rim (16) of the container to provide a primary seal. In one example, in a metal ring (3), the lower edge is curled with equally spaced lugs (13) on the skirt wall. In a plastic ring, the upper rim feature may be omitted.
Abstract:
A horizontal can necking machine assembly (10) includes a plural of main turrets (26) and a plural of transfer starwheels (22). Each main turret includes a main turret shaft (38), a main gear (46) mounted on the main turret shaft, a pusher assembly (30), and a die (34) capable of necking a can body (72) upon actuation of the turret shaft. Each transfer starwheel includes a transfer shaft (54) and a transfer gear (62) mounted on the transfer shaft. The main gears are engaged with the transfer gears such that lines through the main gear center and the centers of opposing transfer gears form an included angle of less than 170 degrees, thereby increasing the angular range available for necking the can body. The main turrets and transfer starwheels may operate to neck and move at least 2800 cans per minute, and each pusher assembly may have a stroke length relative to the die that is at least 38.1 mm (1.5 inches).
Abstract:
A reclosable metal container in the style of a bottle-shaped can has a conventional can body (1) of steel or aluminium to which a metal neck component (10) is seamed. A sleeve (20) of plastics fits over the neck component and a detent (21) inside the sleeve clips it onto the seam. The upper edge of the sleeve is fixed in place by a curl (15) on the upper edge of the neck component. By using a separate neck component and hiding the seam under a sleeve, conventional sizes and material gauges can be used for the can body. Thicker material may be used for the neck component in order to withstand necking forces. Threads (25) for closing the container are provided on the sleeve.
