Lightweight Polymeric Container Finish

A polymeric container including a base, a body, a finish, finish threads, and a tamper lip. The finish threads are at an outer surface of the finish, and are configured to cooperate with closure threads of a closure to secure the closure to the finish. The tamper lip extends from the outer surface of the finish, and is configured to replace the support flange during handling, and to cooperate with a tamper band of the closure. A recess is below the tamper lip. The recess retains the tamper band below the tamper lip when the closure is removed from cooperation with the finish. A gripper ring is between the finish threads and the tamper lip. The gripper ring is configured to cooperate with a gripper for grasping the finish.

Plastic closure having an integrity guarantee element
09850044 · 2017-12-26 · ·

In order to prevent or minimize littering, the invention proposes a plastic closure (1) having a tamper-proof element. The plastic closure has a tamper-proof element that is as small as possible, and the plastic closure is largely secured against loss. The tamper-proof element consists of a plate (50), which is formed as part of the jacket wall (30) of the cover (3) by means of designed breaking point bridges (51, 52) and lies behind a first apron (25) in the closed state before the first opening and engages in a window (26) of the first apron by means of a locking hook. After the first opening, the plate (50) is separated from the cover and is held captive between the first apron (25) and a second, inner apron (27).

Stopper for a container neck

A stopper is disclosed. The stopper includes a tubular skirt, designed to surround a container neck and including, on either side of a weakening line, a removable skirt portion, inwardly provided with means for removable fastening to the neck, and a non-removable skirt portion, inwardly provided with a retaining strip permanently around the container neck. The strip comprises an annular main body whereof a first end is turned opposite the removable skirt portion and integral with the non-removable skirt portion, while a second end is provided to axially abut against a bulge of the container neck and to be radially inserted between the bulge and the skirt.

Cap for closing a container and its method for making the cap

A cap for a container is provided and a related method for making the cap. The cap comprises a side wall extending about an axis and a transversal wall arranged at an end of the side wall, a separation line being provided on the side wall for defining: a retaining ring, which is intended to remain anchored to a neck of the container and is configured to internally engage with an enlargement of the neck; and a closure element which can removably engage the neck, so as to open or close the container. The separation line extends about the axis and is circumferentially interrupted so as to leave a joining portion, between the retaining ring and the closure element, which extends circumferentially for a respective angle, the cap further having an incision line which extends transversally to the axis between the separation line and a free edge of the retaining ring, so that two connecting bands are defined between the separation line and the incision line, the two connecting bands joining the retaining ring to the joining portion. The connecting bands are deformable and the joining portion is externally provided with a projection which projects from the joining portion and is positioned between a separation plane in which the separation line lies and the incision line so that, when the closure element is in the open position and the connecting bands keep the closure element connected to the retaining ring, an edge of the joining portion which, in the closed position, faces the retaining ring, is facing, in the open position, towards a rim of the neck and the projection is resting on the neck in said open position.

CAP WITH A CUTTING ELEMENT

A cap arranged to interact with a spout has a top portion, a sidewall portion depending from the top portion and formed in one piece therewith. The sidewall portion has an interior threading arranged to interact with exterior threading of the neck during an opening operation and during a closing operation. The cap further has a tamper evidence, which is removably attached to the sidewall portion having cutting elements with a first end hingedly attached to the sidewall portion and a free end portion arranged to interact with a membrane portion of the spout. The hinged attachment allows for the cutting element to pivot in an axial direction. Further, the free end portion has a blunt tip and a comparatively sharper cutting edge on a lateral side of the free end portion.

SINGLE ANCHOR CLOSURE
20230174275 · 2023-06-08 ·

A closure includes a closure portion defining a closure top wall and a closure side wall extending from closure top wall. The closure portion is configured to be removed from a finish portion of the container by rotatably disengaging from threads of the finish portion. A tamper evidence band configured to remain engaged with the finish portion when the closure portion is removed from the finish portion. A multiplicity of thin connections attaching the tamper evidence band to the closure portion. The thin connections configured to break apart when the closure portion is removed from the container. An anchor extending from the closure portion to the tamper evidence band. The anchor configured to keep the closure portion attached to the tamper evidence band when the closure portion is removed from the container.

CLOSURE WITH HINGED TAMPER BAND
20170327278 · 2017-11-16 ·

A container assembly including a pouch, spout and closure is provided. The closure includes a tamper-evident band comprising two or more wall sections. Adjacent wall sections of the tamper band may be connected to one another with frangible connectors configured to break upon twist-off of the closure from the spout. The closure also includes one or more support walls supported between an outer wall and central wall of the closure. The closure further includes one or more hinges attaching the ends of the wall sections of the tamper band to the lower ends of the support walls. The hinges are configured to increase the resistance required to break or otherwise distort the frangible connections of the tamper-evident band, so as to prevent or lower the risk of accidental or inadvertent breakage of the tamper-evident band prior to twist-off of the closure from the spout.

Closure device for a container

A closure device for a container having a neck including an annular flange, the closure device comprising: a cap body; a tamper evident (TE) band positioned below the annular flange when assembled in the container; a first hinge and a second hinge defined on the cap body; a leash connected to the TE band, the first hinge and the second hinge; the leash allowing for the cap body to be separated from the TE band during opening, but to remain connected thereto via the leash; a tongue protruding from the cap body between the first and second hinges; when the cap body is actuated from a closed configuration relative to the neck to a fully open position: the leash is configured to retain the cap body to the TE band; an interaction of the tongue and the neck is configured to retain the cap body in the fully open position.

Hinged Closure
20220055804 · 2022-02-24 ·

Hinged closures for containers are provided. The hinged closures allow for a closure that can be held in the open position with a large opening angle. The hinged closures include a lid portion and a skirt portion interconnected by a hinge portion. The hinge portion can be formed from two connecting columns and a central tongue, or two tongues and a central connecting column.

Plastic closure with enhanced performance

A plastic closure embodying the principles of the present invention comprises a closure cap having a top wall portion, and an annular skirt portion depending from the top wall portion. The skirt portion includes an internal thread formation for threaded engagement with the external thread formation of an associated container. In order to facilitate high-speed application, and minimize the use of polymeric material, the closure is configured to exhibit a variation in retention force which decreases in a direction away from the top wall portion of the closure cap.
