    摘要: A method for producing an object made of a polymeric material, said polymeric material having a melting temperature (TF), comprises the steps of: melting the polymeric material; after the step of melting, cooling the polymeric material below the melting temperature (TF) in a cooling zone; severing a dose from a flow of polymeric material coming from the cooling zone by means of a severing element (5); obtaining said object by shaping the dose between a male forming element and a female forming element (10) which move towards one another with a mutual movement speed, the dose having a temperature lower than said melting temperature (TF). Between a start-of-forming configuration, in which the dose is in contact with both the male forming element and the female forming element (10), and a start-of-deceleration configuration, in which the male forming element and the female forming element (10) begin to decelerate relative to one another, the mutual movement speed is greater than 10 mm/s.

    摘要: A closing cap (1) for a container (2) includes an outer shell (3) having a longitudinal axis (X). The outer shell (3) comprises a lateral wall (301) which extends about the axis (X) and has a shape which is tubular and coaxial with the axis (X). An end wall (302; 317) closes the lateral wall (301) at one end and delimits a concavity. The lateral wall (301) is internally provided with a coupling structure (303) configured for removably coupling the cap (1) to a neck (201) of the container (2). An inner component (4; 4′) includes a closing element provided with an inner portion (401; 401′) and an outer flange (402). The closing cap (1) also comprises a containment chamber (5) and an opening promoting assembly (6).

    摘要: An apparatus including a co-extrusion device for extruding a multi-layer structure having at least one primary layer and at least one secondary layer, so that the multi-layer structure leaves the co-extrusion device along an exit direction; a mould provided with a pair of elements, at least one of the elements being movable towards the other in a moulding direction, so as to compression mould an object from a multi-layer dose which was severed from the multi-layer structure; a transport device for carrying the dose towards the mould; an arrangement for modifying orientation of the dose while the dose is being transported by the transport device, so that the dose is introduced into the mould with an orientation in which the secondary layer extends transversely to the moulding direction.
