摘要:
What is described here is a closing cap (1) for a container (2), in particular for a container (2) intended to contain pressurised beverages. The cap comprising a lateral wall (3) extending around an axis (Z) and a transversal wall (4) positioned at one end of the lateral wall (3), a separating line (5) being provided on the lateral wall (3) to define a retaining ring (301), which extends as far as a free edge (304) and is configured to internally engage with a locking ring (206) of a neck (201) of the container (2), and a closing element (302) removably engageable with the neck, so as to open or close the container. The cap comprises an inner thread structure, positioned on the inside of the lateral wall (3) of the closing element (302) to engage with an outer thread structure of the neck (201) and to removably couple the closing element (302) to the neck (201) of the container (2). The inner thread structure (305) extends in a spiral around the axis (Z) and comprises at least two vent grooves (306) which extend axially and interrupt the inner thread structure (305) thereby defining first segments (307), near the transversal wall (4) and second segments (308), over which the first segments (307) are axially superposed; wherein each of the first segments (307) extends angularly in a continuous way and at least one segment of the second segments (308) is interrupted by a vent passage (309), to facilitate the discharge of the pressure.
摘要:
A method comprises the steps of: providing a cap-shaped body (2; 102), said body (2; 102) having a side wall (4) extending around an axis (Z) and a transverse wall (5; 105) arranged transversely to the axis (Z) for delimiting a concavity (7) of the body (2), the transverse wall (5; 105) having an inner face (8; 108) facing the concavity (7) and an outer face (9; 109) opposite the inner face (8; 108); placing a dose (43) of polymeric material on the outer face (9; 109) of the transverse wall (5; 105); compression moulding the dose (43) in contact with the outer face (9; 109), thereby obtaining a shaped element (3) from the dose (43), said shaped element (3) being attached to the transverse wall (5; 105).

A cap for a container comprises a lateral wall (2) extending around an axis (Z) and a transversal wall (3) arranged transversally to the axis (Z), a separating line (4) being provided on the lateral wall (2) to define: - a retaining ring (5) intended to remain anchored to a neck of the container, and - a closing element (6) removably engageable with the neck to open or close the container. The separating line (4) extends around the axis (Z) and is circumferentially interrupted for defining a joining portion (8) which joins the retaining ring (5) and the closing element (6). The cap (1) further has an incision line (21) which extends in the lateral wall (2), transversally to the axis (Z), so that the separating line (4) is axially interposed between the retaining ring (5) and the incision line (21). Two connecting bands (29, 30) are defined between the separating line (4) and the incision line (21) to keep the closing element (6) connected to the retaining ring (5).
摘要:
Described is a combination of a closing cap (1') for a container (2) and a neck (201) of the container (2), wherein the cap (1') comprises a lateral wall (3) extending about an axis (Z) and a transversal wall (4) positioned at an end of the lateral wall (3), a separation line (5') of the lateral wall (3) defining a retaining ring (301'), configured to remain anchored to the neck (201) and a closing element (302) to open or close the container (2). The separation line (5') extends about the axis (Z) and is circumferentially interrupted so as to leave the retaining ring (301) and the closing element (302) joined together. The retaining ring (301') comprises a retaining portion (303), configured to engage internally with a locking ring (202) of the neck (201), the latter projecting from an outer surface of the neck (201) and extending in a direction parallel to the axis (Z) between an upper end (202c) and a lower end (202b). The retaining ring (301') comprises a joining portion (305) which allows the retaining ring (301') to be joined to the closing element (302), a first connecting band (306) and a second connecting band (307), which connect the joining portion (305) to the retaining portion (303), and a tab (308) positioned between the first connecting band (306) and the second connecting band (307). The connecting bands (306; 307) are made by an incision line (7') which comprises a first lateral stretch (702') and a second lateral stretch (703') wherein the first lateral stretch (702') and the second lateral stretch (703'), when the closing element (302) is in a closed condition, are arranged in such a way that when the closing element (302) is in an open condition and the connecting bands (306, 307) keep the closing element (302) connected to the retaining ring (301'), the tab (308) can rest on the neck (201) beyond the upper end (202c) of the locking ring (202) towards the dispensing opening (203).
