The invention is an ergonomic bottle cap having a U-shaped support extending along opposite sides and across the top. The U-shaped support having a top fin across the top wall of the cap and two opposing side tabs extending from the top fin along the annular side wall of the cap. The side tabs integrally molded with the top fin and the cap.

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.

An apparatus and a method are provided for a container cap comprising a plurality of tamper evidence bridges configured to provide evidence that the container cap has been removed from a container by other than a manufacturer of the container. The tamper evidence bridges comprise a small tab of material that extends from a bottom-most edge of the container cap to a neck ring of the container. The tamper evidence bridges are configured to break, or snap, when the container cap is rotated relative to the neck ring. Broken tamper evidence bridges provide readily visible evidence to an end-user of the container that the container cap has been removed by other than the manufacturer of the container. The high visibility of the tamper evidence bridges serves to discourage vendors from attempting to refill and resale of the used containers.

The invention described herein relates broadly to closure assemblies, and methods of use and manufacture thereof. More particularly, certain embodiments relate to assemblies and methods for closing an opening defined by a spout provided on a flexible container utilising a capping member having a plugging portion and a substantially fracturable retaining skirt. Embodiments provide may an adequate seal for the contents contained within bags against the significant pressure placed upon the closure by the often weighty and voluminous contents of the packaging. Furthermore, the closure may be easily and comfortably removable by a user whilst managing the handling of the bag.

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.

The invention relates to a container (1) comprising a container body (4), a closure cap (3), which can be crewed onto said body, and a tamperproof ring (2), which is connected to said cap by way of breakaway webs (10). The closure cap (3) has first driver elements (18), which extend in the axial direction and, when the container (1) is opened for the first time, act on second ramp-like driver elements (19) of the tamperproof ring (2) that extend in the axial direction, and thereby push the tamperproof ring (2) away from the closure cap (3). On a shoulder (6) of the container body (4) that surrounds the container opening, two grooves (22.1, 22.2), one arranged above the other, are provided for receiving and engaging element (23) of the tamperproof ring. The engaging means is engaged first, upper groove (22.1) before the container (1) is opened for the first time and, as a result of the interaction of the driver elements (18, 19) on both sides, is engaged in the second, lower groove (22.2) after the container (1) is opened for the first time.

The invention discloses a push bottle cap, comprising an outer push cap, an inner ejecting cap, a striker and a waterproof cap. The inner ejecting cap is tightly connected to the upper portion of the waterproof cover, forming a hollow chamber; the top of the inner ejecting cap is tightly attached to the upper inner wall of the outer push cap; the upper portion of the inner ejecting cap is provided with a telescoping device; the waterproof cover comprises a waterproof layer, the outer wall of the waterproof cap and the outer push cap are locked together through a fastener, and the waterproof cap is in screwed connection with a bottle in a threaded manner; the striker is inserted into the upper portion of the inner ejecting cap and located in the hollow chamber, the telescoping device surrounds the striker, and the tip of the striker points to but has no contact with the waterproof layer. The shelf life problem of effervescent tablets or other powders is solved, the whole bottle cap structure may be opened smoothly through the outer push cap, and the different needs of people for drinks and purified water can be met.

The technology relates to a cap 1 having a head 4 and a skirt 7 with a circumferential opening area 20 characterized in that the cap 1 may include a transponder 10 including and antenna circuit 14 and a leg circuit 17 the leg circuit 17 extending to the skirt 7 and being non-releasably affixed to the opening area 20, whereby the leg circuit 17 is breakable by disruption of the opening area 20. The transponder 10 stores and is able to transmit information on the integrity of the cap 1 to a reading device.

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.

Present invention provides a compartment as bottled beverages cap for a formula of liquid or powder preparation which may be mixed-up easily with beverages inside of another bottle into a liquid composition. The user simply changes bottle beverage cap with a compartment according to present invention, expel the content into bottle with tear-off mechanism thus the content is mixed-up with water inside of bottle, and creates a ready-to-drink liquid composition. Further present invention provides a breaker having a stopper to against unintentional movements, specifically due to user's accidentally movement, such that said breaker does not tear beverages. This avoids seal becomes leaked which further may create caking of the content and reduced its quality.
