Abstract: A closure element of the press-twist type for closing a container comprises: a capsule having a side wall extending about an axis, and a transverse panel extending transversely to said axis, an annular seal for sealingly engaging with a mouth of the container. The annular seal is made of a PVC-free material and comprises: a side portion arranged in contact with the side wall of the capsule; a front portion extending from the side portion towards said axis; a deformability promoting element for increasing deformability of the front portion, the deformability promoting element comprising a recessed zone configured to be at least partially filled by the material forming the front portion when the front portion is pressed against an edge of the container delimiting the mouth.

Abstract: A method and an apparatus form aluminium screw capsules with a safety ring made of synthetic plastics for tamperproof closing of containers. An aluminium capsule body is inserted into a moulding cavity of a mould conformed and arranged for the overmoulding of a safety ring on an edge of an annular wall of the capsule body. An annular sealing zone is defined for the synthetic plastic material between a first surface of the capsule body and a mould first portion inserted into the central cavity of the capsule body to form a safety ring anchored to the capsule body.

Abstract: A method for applying a sealant to the surface of an object includes forming an annular dose of synthetic plasticised material supplied from an extruder, depositing the dose on the surface of object and compression forming the dose to form a seal. The extruder includes an annular outlet which is opened and closed to deposit successive doses. Each dose that exits the annular outlet is separated from a supply of plasticized material in the extruder.

Abstract: A method and an apparatus for forming annular doses provides a flow of plasticised material supplied by an extruder which passes through a channel that is first cylindrical and then annular. The material exits from an annular outlet in front of which a cutting element passes that separates an annular dose of material. The dose is deposited on a surface of a capsule having a capacity to adhere to the dose that is greater than the cutting element. The surface and the cutting element are distanced from one another in such a manner that the annular dose remaining adhering to the capsule is detached from the element. Detachment can be promoted by a flow of air.

Abstract: An apparatus is disclosed for forming annular doses of synthetic plasticised material supplied from an extruder, in which the doses are applied to a surface of a capsule and the seals of the capsules are then compression-formed. The apparatus includes one tubular wall that has a longitudinal axis and is axially movable for closing an annular outlet from which the synthetic plasticised material exits with a component that is normal to the longitudinal axis. The tubular wall has a cutting edge that shears the plasticised material during the closing movement in order to separate the annular dose, formed outside the outlet, from the material that remains inside the outlet.

The plant includes, along the extension of the longitudinal transfer direction, a device for the digital printing of the cup-shaped bodies, and a component for controlling the position of the top edge of the cup-shaped bodies on the resting surface, the component being connected to the digital printing device.

Abstract: 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.
