A bottle-shaped can includes a cap having an excellent sealing ability but easy to be opened. A top section includes a leading end section as an upper end of a neck portion, a diametrically-largest section formed beneath the leading end section, a diametrically-shrunk section extending downwardly from the diametrically-largest section, and an outer circumferential wall section extending downwardly from the diametrically-shrunk section. The leading end section, the diametrically-largest section, and diametrically-shrunk section form a smooth curved surface. A curvature of the diametrically-largest section in a cross-section is zero or negative value, given that a curvature of the diametrically-shrunk section is positive value. A flexion section is formed between the diametrically-shrunk section and the outer circumferential wall section. The outer diameter of the outer circumferential wall section in which the curvature is zero or negative value is larger than an outer diameter of the flexion section.

A biodegradable container including a unitary polymeric body element having a top portion and a cylindrical body portion. The top portion has a cylindrical neck wherein the cylindrical neck defines an inner surface and an outer surface. The container further includes a polymeric bottom element welded to the cylindrical body portion of the unitary polymeric body element. A polymeric cap defines an internal rim configured to be received by the inner surface of the cylindrical neck. The polymeric cap includes an external cover having an interior surface which may be tapered so that the outer surface of the cylindrical neck and the interior surface of the external cover form an inner seal. The interior surface of the external cover may also form an outer seal with the outer surface of the cylindrical neck when the polymeric cap is in a closed position.

A screw cap produced by a bi-injection moulding process is disclosed herein in which discrete thermoplastics are moulded sequentially for resulting correspondingly into a soft inner lip and outer hard shell for sealing containers or conduits having an externally threaded neck, said containers or conduits being directed at holding or conveying chemical, food, and pharmaceutical preparations.

A container closure and methods are disclosed for providing visible evidence of removal of the closure from a container after installation by a manufacturer. The closure includes tamper evidence bridges comprising small tabs of material that extend from a bottom-most edge of the closure to a tamper evidence ledge of the container. The bridges break when the closure is rotated relative to the tamper evidence ledge, thereby providing readily visible evidence that the closure has been removed after installation by the manufacturer. In some embodiments, a tamper evidence closure engages with threads of a finish of the container. Cam locks around the perimeter of the tamper evidence closure are permanently flared by cams on the finish during loosening of the closure. Outward flaring of the cam locks provides a visual indication that the tamper evidence closure has been loosened after installation by a manufacturer.

The invention is directed to a closure (1) having a base (3) with a top deck (4) and a therewith adjacent skirt (5) extending in an axial direction (z) comprising an internal thread (6). The closure (1) is comprising a sealing arrangement (16) with an inner seal (18) extending in the axial direction (z) from the top deck (4). The inner seal (18) is having an inner annular sealing surface (29) arranged radially inward with respect to an outer seal (17) and pointing in an outward direction. The sealing arrangement further comprises an outer seal (17), which in its cross-section comprises a base section (20) extending in the axial direction (z) from the top deck (4) and an end section (21), which is bend inwardly with respect to the course of the base section (20) in the direction of the inner seal (18) and which terminates in a sealing surface (22) pointing in an inward direction.

A method for making a cap (1) for a container comprises a step of forming in a mould, in which the following are made: 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 is joined to the cap body, 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); a connecting window (4) including a connecting band (40) and a film (400) which is thinner than the connecting band (40), the film (400) being adjacent to a first flank (43) and a second flank (44) of the connecting band (40), each of the first flank (43) and second flank (44) extending from a first end (41) of the connecting band (40) connected to the retaining portion (31) to a second end (42) of the connecting band (40) connected to the side wall (21) of the body (2), along the whole length of the first (43) and of the second flank (44).

A flip-top closure includes first and second polymeric closure portions. The first closure portion includes a top wall portion, a sealing mechanism and an annular skirt portion. The second closure portion includes a tamper-evident band. The closure portions are attached by a line of weakness. The closure portions are further attached via a hinge. The hinge includes a locking tab, a flexible tab and linking segments. The locking tab extends further outwardly from a center of the closure in a closed position than the flexible tab and the linking segments. During the opening of the flip-top closure, the locking tab moves and passes the flexible tab such that the flip-top closure locks in a fully open position.

A method for producing a cap for a container wherein the cap includes a retaining ring suitable for being associated with a neck of the container and a closure element hinged to the retaining ring for opening or closing an opening defined by the neck of the container. The method includes providing a cup-shaped body having a side wall extending about an axis and an end wall extending transversely to the axis, and cutting the side wall along a separation line for defining the retaining ring and the closure element such that during the cutting step there is interacting with the material forming the side wall along an angular extension of the side wall about the axis as to leave intact at least one connection band which connects the retaining ring to the closure element, and producing at least one delimitation line which laterally delimits the connection band.

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.
