A tamper-evident cap is disclosed having a circular closure member, a cylindrical annular wall depending generally from the periphery of the closure member terminating with a base and having a plurality of serrations, and a tamper-evident band circumferentially positioned around the base having teeth and attached to a portion of the base. The tamper-evident band may be mounted to the base by at least one of the teeth or attached by at least one of the serrations extending below the base. The interior and/or exterior of the cylindrical wall may be stepped. The tamper-evident band may have a groove between the teeth for retaining the tamper-evident band on a neck finish. A neck finish having at least one set of teeth and optional raised portions for securing the tamper-evident band in place is also disclosed. The neck finish may be stepped to correspond with a cap having a cylindrical wall with a stepped interior. A cap and neck finish combination for a container is also disclosed.

Tamper-evident container cap and neck finish

A blow molded container has a cylindrical neck portion with novel seven circumferentially spaced continuous spiral thread configurations on its exterior to immediately receive and engage an improved tamper indicating flexible cap comprising a top with an annular depending wall on its peripheral edge and seven circumferentially spaced continuous spiral thread configurations on the inner surface of the annular depending wall. The novel constructions enable the tamper indicating flexible cap to immediately engage the lead-in ends of the seven circumferentially spaced thread patterns on the exterior of the neck of the container without the heretofore necessary rotation of the prior art caps in order to engage the single spiral thread configuration on the neck of the container.

Neck finish for a container and a matching registering multiple thread

A tamper evident resealable cap for use on a bottle, the cap having an upstanding pour spout registering with an opening in the center of the cap and a smaller diameter plug positioned thereabove on a plurality of upwardly angled legs on the pour spout. The cap having a flexible annular ring attached to the cap by a plurality of radially extending frangible elements with the plurality of circumferentially spaced radially inwardly extending angular projections arranged for registration with a neck portion on the bottle to prevent rotation in one direction without removal of the ring.

Container and closure resealable bottle cap with push pull closure

A container for use in combination with a closure has a threaded neck and a flexible lip portion which extends inwardly and upwardly from the top of the neck portion and which defines the opening to the container. The closure has a top portion from which depends a threaded annular skirt which cooperates with the threaded neck portion. The upper surface of the threads on the annular skirt have a plurality of radially extending small upwardly pointed ribs defining fastening configurations registrable with a plurality of radially extending small downwardly pointed ribs on the lower surfaces of the thread on the neck portion of the container. The threads of the closure are smaller than the threads on the neck of the container so as to extend a lesser distance toward the neck of the container than the distance the thread on the neck of the container extends toward the closure. A flexible annular ring is attached to the closure by a plurality of radially extending frangible elements has a plurality of circumferentially spaced radially inwardly extending angular projections arranged for registry with a ratchet section on the neck portion of the container when the closure and ring are rotated in one direction and so formed as to prevent rotation of said annular ring in the opposite direction without removal to indicate tampering with the closure.

Container and closure with cooperating threaded portions having

A cap for a bottle, such as a blow molded sports's water bottle, having a neck surrounding an opening therein and a pair of vertically spaced fastening configurations on the exterior thereof, the cap having an annular tear skirt depending therefrom, the tear skirt having a pull tab for the removal thereof, the cap having an upstanding pour spout or tube registering with an opening in the center of the cap and a smaller diameter plug positioned thereabove on a plurality of upwardly angled legs on said pour spout. A pair of annular ribs are formed on the exterior of the pour spout to permit vertical movement of a top cap having an opening therein registrable with said plug. An annular ring having an inturned annular flange thereon is positioned on the pour spout below one of said annular ribs and is detachably secured to the top cap by a plurality of frangible elements. The bottle cap forms a first closure on the water bottle and the top cap forms a second closure, the bottle cap being replaceable on the water bottle when the annular tear skirt is removed.

Resealable bottle cap with push-pull closure

A tamper indicating container and closure combination in which the container has configurations about the neck thereof registering with configurations on a separate portion of a closure engageable therewith, which separate portion is separated from the closure when the closure is removed from the container. A sealing disc is positioned in the closure by limited frictional engagement therewith so that when the closure is removed from the container, the separable portion of the closure remains on the container as an indicator and the sealing disc remains in sealing relation on the container and must be wholly or partially removed by a tab thereon to gain access to the contents of the container whereby the sealing disc and tab forms a second indicator.

Closure assembly with two tamper indicators

A flexible closure for a container such as a blow molded jug having an inturned flange surrounding an opening therein and a pair of vertically spaced fastening configurations on the neck of the container, the closure having a resilient cap portion with an annular flange depending therefrom, vertically spaced fastening configurations on said annular flange positioned for registry with said fastening configurations on said neck, a lower portion of said annular flange forming a tear skirt. The fastening configurations on the neck of the container and the fastenign configurations on the annular flange of the flexible closure forming dual fasteners, either of which is capable of holding the closure on the neck of the container. One or more resilient flexible depending ribs on the resilient cap portion sealingly engage said inturned annular flange surrounding said opening.

Tamper indicating closure for containers

A closure for a container such as a blow molded bottle having a neck surrounding an opening therein defined by an inturned annular flange formed by a spin finish operation on the blow molded bottle, the closure having a cap portion and an annular tear skirt depending therefrom, the closure having an annular frangible wall joining the cap portion and the tear skirt and fastening configurations on the cap portion and the tear skirt, the cap portion having a resilient top portion with cross sectionally rounded annular sealing flanges depending therefrom arranged for sealing registry with the upper surface of the inturned annular flange defining the opening in the bottle.

Snap on tamper indicating closure for containers

A flexible closure for a container, such as a blow molded jug, having a neck portion with an inturned flexible flange surrounding an opening therein and a pair of vertically spaced fastening configurations on the exterior thereof; the closure having a cap portion with an annular depending flange on its peripheral edge and at least one depending annular flexible sealing flange inwardly thereof for engagement with said inturned flange on said neck portion. A tear skirt is removably attached to the annular depending flange, the tear skirt having a pull tab for the removal thereof. An out-turned annular flange is formed on said tear skirt and a plurality of circumferencially placed gussets join said angular flange and said tear skirt. The closure has dual fastening configurations, either one of which is capable of holding the closure on the neck portion of the container. When the tear skirt of the closure is removed the opposite sides of the depending flange of the flexible closure may be moved inwardly to engage ribs on the neck portion so that twisting the closure removes it and the annular sealing flange from the neck of the container.
