Abstract: A fitment is provided for incorporation into a closure assembly to provide at least one high-pressure seal suitable for maintaining high-positive pressures in a container having pressurized contents, such as carbonated beverages. The fitment and closure assembly also provide for bi-modal dispensing operations, because the fitment it can be removed from the closure assembly to provide alternative flow characteristics from the container through the closure assembly. The fitment may also be provided with one or more projections adapted to engage a thread on the closure body such that rotation of the closure body relative to the container results in removal of the fitment from the container. The fitment may also be provided with one or more projections for engaging the closure body to limit its movement relative to the container, thereby defining a fully open dispensing position of the closure body.

Abstract: In a dispensing system comprising a container having at least two storage chambers, each for a fluent material, the finishes of the respective chambers are arranged in a contiguous pair defining a cylindrical surface having outer threads, except for two anti-rotational flats. Each finish defines an outlet. A valve of a type that remains closed until opened by a differential between inside pressure and outside pressure overlies the outlet defined by each finish. A fitment defines a mixing chamber having two inlets, one for each storage chamber, and having an outlet. The fitment has two skirts, each having an inner surface having at least one rib, each defining an anti-rotational flat. The fitment fits over the paired finishes and over the valves so that the antirotational flats on the ribs engage the anti-rotational flats on the paired finishes. A collar having inner threads is threaded onto the paired finishes so as to hold the fitment, which holds the valves.

Abstract: A unitary article is provided in a form which can be reconfigured as a two-piece dispensing closure. According to the method, the unitary article is molded with frangible webs connecting a ring to a body so that the ring is axially offset from, but concentric with, the cylindrical wall of the body. Subsequently, the frangible webs are broken, and the ring is moved axially to a location concentric with the body cylindrical wall to form the assembled closure. In the assembled closure the body has a closed end and an open end suitable for mounting on a container. The cylindrical wall of the body defines a discharge passage for communicating with the container for dispensing the contents thereof. The ring defines a dispensing orifice and accommodates rotation between a dispensing position in which the passage and orifice are at least partially aligned and a closed position in which the passage is occluded by the ring.

Abstract: A container closure includes a body for mounting on the container. The body defines a dispensing orifice. A flow control device, such as a lid, is disposed on the body for being moved between positions opening and closing the dispensing orifice. A tamper-indicating member is provided as a unitary extension from the lid. A first frangible web connects the member to the lid. An anchor is connected with a second frangible web to another portion of the tamper-indicating member, and the anchor is retained by the closure body. The tamper-indicating member also includes a graspable pull tab. The tab can be pulled to completely sever the frangible webs connecting the tamper-indicating member to the lid and to the anchor. This permits the lid to be opened while providing evidence of tampering with the closure.
