A closure having a liner is provided. The liner forms one or more venting recesses that facilitate relieving pressure from a container to which the closure is affixed. In embodiments the liner extends from an outer surface of an annular wall through an outer disc of the liner.

A container closure of synthetic resin is for a container having a mouth-and-neck portion with an external thread on an outer periphery thereof and an engaging jaw portion positioned below the external thread. The container closure includes a body and a tamper evident skirt portion, and is configured to not be entirely separated from the mouth-and-neck portion of the container even after unsealing the container at the mouth-and-neck portion. At least in an angle region in which a protruding piece on a skirt wall of the body is present, an extending portion is defined at an engaging piece on the tamper evident skirt portion. When the container closure is mounted on the mouth-and-neck portion of the container, the extending portion of the container closure is positioned between the engaging jaw portion of the mouth-and-neck portion of the container and the tamper evident skirt portion of the container closure.

A canister includes a closure configured to mount on a container to close an open mouth into a product storage region formed in the container. The closure includes a lid and a lid retainer coupled to the lid. The lid retainer is configured to mate with an external thread on the container to retain the closure in a mounted position on the container.

A sealing system for container comprising material and a method using the system. The present invention provides a sealing system for sealing a container comprising material, wherein the system comprises at least a first part which is a cap for sealing a container comprising a seal; and a second part which is a coupling member that is mounted to a dispenser unit, wherein the coupling of both parts with each other is configured that they can be twisted against each other while preventing axial movement of first and second part.

A preform is provided for blow-molding to form a container. The preform includes a finish portion for rotatably engaging a closure to seal contents within an interior of the container. The finish portion comprises a cylindrical body that begins at an opening to the interior and extends to and includes a tamper evidence ledge. A bevel at a beginning of the opening receives a plug seal of the closure. A sealing surface adjacent to the bevel is disposed along an interior of the finish portion and includes a polished buffer zone to cooperate with the plug seal to seal the container. A transition surface extends from the sealing surface to a handling surface that receives equipment to form the preform into the container. In some embodiments, the transition surface includes a polished buffer zone to cooperate with an end of the plug seal to seal the contents in the container.

A closure may have a top wall and a side wall depending from the top wall. A plug seal device may depend from said top wall within the side wall. The plug seal device may have an upper section, a lower section, and a sealing section proximate the boundary between the upper section and the lower section. The sealing section is operable such that when the plug seal device is inserted in an opening to an inner cavity in a container, the sealing section engages with an inner container surface to provide a seal between an inner cavity of the container and the external environment.

A fuel cap assembly according to an example of the present disclosure includes a fuel cap and a pipe stub that extends from the fuel cap and defines a first internal passage. A sensor element and a fuel tube are adjacent to each other and both extend from the fuel cap through the first internal passage. A cylindrical coupler is composed of an elastomer and defines a second internal passage that extends between an inlet port and an outlet port. The inlet port has a first inner diameter and the pipe stub is receivable into the inlet port. The outlet port has a second inner diameter that differs from the first inner diameter.

Described is a closing cap (1) for a container (2), which 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) being provided on the lateral wall (3) to form a retaining ring (301), which is configured to remain anchored to a neck (201) of the container (2) and extends up to a free edge (304), and a closing element (302) removably engageable with the neck (201), so as to open or close the container (2). The separation line (5) extends about the axis (Z) and is circumferentially interrupted to form in the lateral wall (3) a joining zone (305), which extends for a first angle (a), in which the retaining ring (301) and the closing element (302) are joined. The cap (1) comprises a tab (308), made in the joining zone (305), which extends circumferentially for a second angle (β) and is connected to the joining zone (305); the retaining ring (301) comprising a retaining portion (303) and a free portion (306), wherein the retaining portion (303) comprises an engaging element configured to engage internally with a locking ring (202) of the neck (201) during a passage from a closed condition to an open condition of the closing element (302), and wherein the free portion (306) comprises a movement element which extends circumferentially at least in the second angle (β) and is configured, during said passage, to allow a movement of the free portion (306) along an axis parallel to the axis (Z).

A cap for a container comprises: a retaining ring intended to remain associated with a neck of the container; a closing element movable between a closed position and an open position; at least one connecting band for keeping the closing element connected to the retaining ring even in the open position.

The retaining ring comprises engaging members suitable for engaging with the neck in order to prevent the retaining ring from being pulled off the neck. The engaging members comprise first engaging elements and second engaging elements which extend towards the inside of the retaining ring. The first engaging elements have a shape different from the second engaging elements, so as to be in contact with the neck in the open position, in order to obstruct rotation of the retaining ring around the neck.

A cap (1) for a container comprises: a body (2), configured to be coupled and uncoupled relative to the neck of the container and including an internally threaded side wall (21), which extends around a longitudinal axis (A), and a transverse wall (22); a tamper evident ring (3), including a retaining element (31), configured to engage a locking member on the neck of the container, and a joining portion (32), where the tamper evident ring (3) is joined to the cap body (2), the joining portion (32) being configured to be torn along a perimeter surrounding the longitudinal axis (A) in response to a movement of the body (2) away from the tamper evident ring (3), wherein the cap (1) comprises a connecting window (4) including a connecting band (40) and a film (400) which is thinner than the connecting band (40).
