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.

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.

A novel snap on pull off tamper indicating cap and neck configuration for containers, the cap having 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. A removable tear skirt with continuous opposing groups of ratchet teeth on its inner surface depends from the outer peripheral edge of an out-turned flange on said annular wall. An inturned continuous annular rib on said annular depending wall engages on and deforms the neck configuration. The tear skirt is joined to the flange with multiple frangible connections from the ratchet teeth, a pull tab on the tear skirt with frangible lines requiring removal of the tab and tear skirt from the cap before the cap can be rotated. The novel construction also enabling lead-in ends of the seven circumferentially spaced thread patterns on the depending wall to immediately engage the neck configuration having registering circumferentially spaced continuous spiral thread configurations on its exterior thereof.

A neck finish for a tamper evident bottle is disclosed having at least ten helically spaced threads which extend along a substantial length of the exterior wall of the neck. The neck finish may include one or two annular ring flanges to accept a snap-on cap. Also disclosed are tamper evident caps having at least ten helically spaced threads positioned on the inner surface of the cap. In one embodiment, the cap includes one or two annular ring flanges to engage the ring flanges on the disclosed neck finish. Another tamper evident cap includes ten helically spaced thread which are adapted to engage at least some portion of threads on a neck finish.

An auto rotation capping device for use on bottle cappers to provide for a final partial tightening rotation of a pre-positioned tamper evident push on cap. The auto rotation cap tightening device includes a support and guide housing with a recessed cap engagement chuck that imparts partial rotation to the cap by the vertical movement of the bottle cap against the chuck.

A bottle support apparatus to supply additional outboard support to a resilient thermoplastic bottle during capping with a bottle capping device. The outboard support device provides additional arcuate support for the bottle neck by encircling the remaining free portion of the lower bottle neck not engaged by the capping machine so that thin walled thermoplastic resin bottles will not be distorted by the force of the capping machine during operation.

A removable tear skirt with continuous ratchet teeth on its inner surface depends from the outer peripheral edge of an outturned flange on said annular wall. An annular rib on said ratchet teeth, the tear skirt is joined to the flange with only the points of the ratchet teeth, a pull tab on the tear skirt with frangible lines enabling removing of the tab and tear skirt from the cap. Ratchet teeth on the container have a continuous longitudinally extending notch within for interlocking registration with the annular rib on the ratchet teeth of the tear skirt.
