The present invention relates to a cap for a container. The cap comprises a main body having a top plate and a circular sidewall, wherein one periphery of the circular sidewall connects to the top plate forming a closed end, and the other periphery of the circular sidewall at the opposite side of the closed end forms an opened end; and a ring member located at the opened end of the main body, separated from the main body by a first incision line, and connected to the main body by a plurality of connecting portions, wherein a plurality of second incision lines locate on the main body or the ring member and locate at one side of the plurality of connecting portions. The cap provided by the present invention will, while in its open and/or closed state, continue to be connected to its container.

A closure assembly (20) that includes a cap or overcap (28) and a fitment (24) for a container is provided wherein the fitment (24) has a laterally projecting shear member (40), and the overcap (28) has an aperture (74) for initially receiving the shear member (40) when the overcap (28) and fitment (24) are in an initially assembled orientation or condition. The aperture (74) and the shear member (40) cooperate in the initially assembled orientation such that when subjected to a flow of a sterilizing gas, turbulence is created in the sterilizing gas flow to enhance sterilization of the combination. The closure assembly (20) may, instead, or additionally, be provided wherein the overcap (28) has an elongate, hollow plug (58) for establishing a first seal between the fitment (24) and the overcap (28) in the initially assembled orientation, and the wherein overcap (28) has a skirt (50) for establishing a second seal between the fitment (24) and the overcap (28) in the initially assembled orientation.

A tamper evident closure and spout are provided. The closure includes an outer wall and a central wall supported from the outer wall. The closure defines a passage extending between an upper edge and a lower edge of the closure and located between an inner surface of the outer wall and an outer surface of the central wall. The closure includes a tamper-indicating band extending from the central wall. The spout includes a wall portion and a central channel extending through the wall portion between an inlet opening and an outlet opening. The spout includes a structure located below the inlet opening the first and second exterior surfaces are both angled toward the central axis of the spout.

A low-spread metal elongated bottle and its production method are described for reducing rejection rates associated with the production of metal bottles at high speeds. The elongated bottle includes a sheet metal formed body. The sheet metal has a low spread between a yield state corresponding to the yield stress of the sheet metal and an ultimate tensile state corresponding to the ultimate tensile stress of the sheet metal. The body further includes a concave bottom portion having a circular perimeter. A cylindrical portion extends from the circular perimeter of the bottom portion and has a uniform diameter. A neck portion extends from the cylindrical portion and has a tapered profile. The neck portion may include a threaded portion including threads exposed on the outer surface of the neck portion or an area for crimping of a crown.

A pre-assembled container closure assembly (1) has a plastic spout body (2) with a tubular neck (4) delimiting a product passage (6) that extends to a mouth opening (8) of the neck. A rotational cap (30) is secured in closed position on the neck. The cap has a cap body including a top wall (31) and a skirt (32). The cap body further includes an annular inner sealing ring (40) depending from the top wall. The inside of the neck is provided with an inward tapering annular guide surface (15) that is contacted by the inner sealing ring when the cap is secured onto the spout body and then causes an elastic deformation of the inner sealing ring and/or the neck. The inner sealing ring is embodied such that the first annular sealing surface (41) on the exterior side of the inner sealing ring and a lowermost annular surface (43) of the interior side of the sealing ring adjoin one another directly at an apex (44) which forms the lower edge of the inner sealing ring, and in that—with the cap in closed position—said apex lies against the interior side of the neck, said lowermost annular surface extending from said apex to form an angle of at least 90° with an exposed surface portion of the interior side of the neck directly below said apex so as to avoid the presence of any gap between the inner sealing ring and the neck at said apex.

A closure inner shell includes an annular skirt extending axially from a base wall and having an external thread segment. The base wall may have a central passage and the skirt may have circumferentially spaced petals. A closure outer shell may include a vented plug seal extending axially through the central passage of the inner shell, and an annular outer skirt to engage the petals of the inner shell and having an internal thread segment for threaded engagement with the external thread segment of the inner shell. A container may include a container neck bead for engagement with the petals, an inner annular sealing surface for engagement with the plug seal, and an inner annular relief to cooperate with the vented plug seal to establish a vent path.
摘要:
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.

The present invention relates to a tamper-evident closure of the roll-on type which comprises an engagement surface, suitable for engaging with a corresponding engagement surface provided on the neck of a container, wherein the engagement surfaces permit the complete removal of the closure after the first opening.
摘要:
A tamper-evident closure for a container comprises two or more parts and is movable from a first position to a second position in an opening event, the movement to the second position generating two or more gaps between and/or within the parts, the closure further comprising means for preventing closing of the gaps whereby to confirm the opening event has occurred.
摘要:
A closure assembly comprises an article (1) forming a tubular neck (2) around a product passage (3) in said article. The neck forms a mouth at a top end of said product passage. The assembly further comprises a rotational cap (20) that is injection moulded of plastic material and that is secured on or to be secured on said neck of the article. The cap seals the product passage in closed position of the cap on said neck, and the cap—for removal of the cap from the neck of the article by a user to open the product passage—is adapted to be manually rotated from the closed position in an opening direction.
