A method for manufacturing a cap, which can insert a sheet member easily into a predetermined position of an upper part inside a cap body, without causing deformation to the sheet member or the cap body. The sheet member does not separate when a container is brought to reduced pressure. An annular protruding portion protruding on a lower surface side is formed in an annular flat region of a sheet member of an inside plug. After or at the same time that the sheet member is inserted into and installed at a predetermined position within a cap body, the annular protruding portion is pressed axially toward a top panel wall and deformed so as to become close to a flat shape, to enlarge the outer diameter of the sheet member. The inside plug is thereby held to be inseparable from inside a skirt wall and to be axially movable.

A metal closure (1) comprising a panel (10) and a depending side wall (14) terminating in a cut edge (15), the inner surface of the closure having a plurality of coating layers applied (21-27) such that at least one of the coating layers extends to the cut edge and the coating thickness at and in proximity to the cut edge is less than the thickness at one or more other regions of the inner surface.

A vacuum chuck adapted for mounting on a lower turret assembly. The lower turret assembly is part a sealant liner applicator. The sealant liner applicator includes an upper turret assembly and a sealant gun, under computer control. The sealant gun is used for applying a sealant around a periphery of an inside of a can or jar lid. The vacuum chuck includes in one embodiment an impeller, with spiral vanes, for creating vacuum air. The impeller is mounted on top of an involute. A top portion of the impeller is adapted for receiving the can lid and held thereon using the vacuum air produced when the impeller and the involute are spun at high speeds, in a range of 1000 to 4000 rpm, on a lower turret assembly.

A method of embossing a crown cap comprises the steps of: detecting a pre-printed drawing on the bottom of the crown cap, varying the angular positioning of the crown cap so as to position the drawing according to a preset positioning, and impressing a raised/recessed pictogram on the bottom of the crown cap. The pre-printed drawing and the embossed pictogram will have a desired reciprocal position.

A device for the application of a liquid fluid to a peripheral area of a lid using pistols for injecting said liquid fluid. The device includes an articulated mechanical device combined with at least two coaxial tubular shafts: a main supply shaft and a lower shaft, where a lower end of the main supply shaft connects to a first part of the articulated mechanical device, while a second part of the articulated mechanical device connects to a lower end of the lower shaft. The two coaxial tubular shafts rotate independently by means of transmission devices. The main supply shaft is arranged in an inner hole of the lower shaft, which is arranged coaxially around at least one section of the main supply shaft.

In order to minimize the sliding friction between the locking parts, that is, between the pawl and the rotary latch of a motor vehicle door lock, it is advantageous if, during the production process, the different latch surfaces of both locking parts are provided with a stamped contour have straight grooves and also with a stamped contour, characterized in that the provided grooves are oblique. The grooves which are oblique to the latch surface on the pawl can be produced such that the entire pawl or also the rotary latch are connected in an oblique manner to the base of the lock case housing which can be produced in several ways. Between the straight grooves and the oblique grooves, at least two coverings are provided which ensure that both locking parts are in mutual contact reducing the friction.

A tear-off lid with a curled edge of the removal opening is formed such that before the edge is curled, a plastics layer provided as a band of low thickness and preferably only 0.1 mm thickness is applied to the collar of the lid ring. In this way, a good seal of the cut edge of the tear-off lid is produced by economical means and with the possibility for production at a high rate.
