The present invention aims at closing a receptacle (1) provided with an opening (2) as tightly as possible while keeping low the amount of material required for a closure (3) used for this purpose. To this end, a tool (10) is suggested that closes the opening (2) of the receptacle (1) by means of the closure (3). The tool (10) comprises a tool plate (12) configured such that it is adapted to be introduced into the opening (2) of the receptacle (1). The tool further comprises at least one roll (11) that is arranged on the tool plate (12). The at least one roll (11) is adapted to be deflected radially outwards from a starting position into a closing position and returns to its starting position, so that a radial force can be caused to act on a closure rim (4) of the closure (3) for a limited period of time, the closure rim (4) being arranged between the at least one roll (11) and the receptacle inner side (5).

The present invention has an object of providing a seaming device that can prevent the leakage of a lubricating oil from the in-machine housing of a chuck unit into a seaming operation space, prevent the occurrence of a defective product contaminated by the lubricating oil, and eliminate heat elongation due to heat generation to accurately maintain a seaming dimension. Provided is a seaming device (100) including: a chuck unit (320) that positions a lid (F) mounted on a can C; and a seaming unit (410) that seams the lid to the can, wherein the chuck unit has a spindle (325) having a chuck (321) for positioning the lid attached at a lower end thereof, a bearing (326) that rotatably supports the spindle, and a non-contact type oil seal mechanism for sealing between the spindle and the in-machine housing at a position below the bearing.

A seaming device includes a seaming head for fixing the lid to the container, first and second seaming rollers and a rotary drive. The seaming head is arranged between the first and second seaming rollers such that the container with the lid is fixed centered between the first and second seaming rollers in the operating state. The rotary drive is drive-connected to the first and second seaming rollers, the first and second seaming rollers rotated about the seaming head by the rotary drive, so that, in the operating state, the first and second seaming rollers are moved along a circumference of the container immovably fixed by the seaming head, and a container flange of the container are seamed with a lid flange of the lid.

An apparatus includes a tool operable to releasably join a metallic end closure to a metallic container. In one embodiment, the tool is configured to form a thread in the closure and the container. The tool may optionally crimp the closure to the container. Once sealed, the container can be opened by rotating the closure in an opening direction. The closure can subsequently re-close the container by rotating the closure in a closing direction.

A can seaming apparatus including a frame, a can handling assembly, a can driving assembly and a seaming assembly. The can seaming apparatus is configured to seal a lid to a can through a double seam can seal. The can is positioned and clamped between an upper and a lower chuck. The can driving assembly spins the can and the upper and lower chucks about an axis. The seaming assembly includes two rollers which can selectively be directed to engage the can to form the necessary crimping operations.

To manufacture a metal can having a tear-open lid and having a storage space for an object above the tear-open lid, the following procedure is used: first, a top edge of the can which has a smaller diameter than the inside diameter of the can body is formed, wherein a transition region (6) is formed. After the tear-open lid has been attached, this transition region is deep drawn so that the tear-open lid (2) is displaced towards the bottom (5) of the can. This produces the storage space. This procedure allows previously formed tear-open lids to be used, which safely guarantees the imperviousness of the seal of the tear-open lid.

An arrangement for disinfecting can lids (32) and for closing cans includes a feed device (12) which feeds a can closing unit (24). Receiving portions (30) for individual can lids (32) are arranged in the feed device (12). The feed device (12) is situated in the feed region of the can closing unit (24). At least one sterilization device (18, 20), for can lids (32) received individually in the feed device (12), is arranged in a conveying region of the feed device.

A crimping unit (1) having a first plate (10); a first lever (50) equipped with a winding wheel (54), a second lever (60) equipped with a crushing wheel (64), a winding actuator connected to the first lever (50), and a crushing actuator connected to the second lever (60). The winding actuator and the crushing actuator are governed by an electronic control unit (7) to vary the distance between the winding wheel (54) and/or the crushing wheel (65) of the first axis according to the angular position of the first plate (10) around the first axis.

Receiving portions (30) for individual can lids (32) are arranged in the feed device (12). The feed device (12) is situated in the feed region of the can closing unit (24). At least one sterilization device (18, 20), for can lids (32) received individually in the feed device (12), is arranged in a conveying region of the feed device.

A counter-pressure filler system includes a vertically-translatable platform capable of supporting a container, a pressurizable chamber having an entrance aperture, the chamber enclosing a seaming chuck and at least one seaming roller, a vertically-translatable enclosure comprising an upper portion configured to engage a portion of said chamber around the entrance aperture, thereby creating a pressurizable atmosphere within said vertically-translatable enclosure and the pressurizable chamber. The seaming chuck is configured to allow a beverage ingredient to pass therethrough and into said container.
