Patent ID: 7882977

Claim:
A tamper-evident assembly for use with a fluid dispensing container for flowable material, the assembly comprising: (A) an annular flange, for attachment to a container; (B) a spout, projecting upwardly from the annular flange and having an upper end and a lower end, the spout defining a dispensing passage therethrough and having at least one external annular rib; and (C) a cap, having a top with an external depending skirt and a frangible tamper indicating band releasably attached to the skirt, the cap further including an internal skirt depending from the top and spaced inwardly from the external skirt and operable to be received within the fluid passage to provide a seal between the cap and the spout; wherein the assembly has a first pre-cap position in which the cap is received on the upper end of the spout, with the frangible tamper indicating band positioned above the external annular rib and abutting a top surface of the external annular rib, and the internal skirt being received within the passage and contacting an internal annular surface of the spout providing a seal between the internal skirt and the internal annular surface of the spout; and wherein the assembly has a second full-cap position in which the cap is located on the lower end of the spout, with the external annular rib being located between the external skirt and the tamper indicating band, and the upper end of the spout being located adjacent the top of the cap, the internal skirt being received within the passage and providing a seal therebetween; wherein the cap and spout have cooperating detent and locking elements to allow the assembly, when secured to a container, to move from: (a) a first pre-cap position, where the cap is removably sealed to the spout and the tamper evident band is not broken when the cap is removed for filling, to: (b) a second full-cap position when the cap is removably sealed to the spout providing that the tamper evident band is broken upon removal of the cap from its second full-cap position to dispense flowable material from the container; wherein the assembly in the first pre-cap position or the second full-cap position provides an aseptic seal between the cap and the spout; wherein the cap is received on the upper end of the spout for the pre-cap position or the full-cap position by a push-on process; and wherein the cap is removed from the spout either from the pre-cap position or the full-cap position by a pull-off process.
