Abstract
A tamper-evident dispensing structure is provided for being sealed to a collapsible pouch. The structure includes a fitment and a lid structure which are each separately molded and which can be subsequently non-releasably attached. The fitment is adapted to be sealed to a periphery of the pouch at an opening in the pouch. The fitment has a receiver and has at least one dispensing flow passage through the fitment. The lid structure includes (1) a base for being fixedly and non-releasably attached to the fitment receiver, (2) a cap for being sealingly and removably mounted on the fitment to occlude the dispensing passage, and (3) at least a first frangible web connecting the cap to the base for accommodating separation of the cap from the base.

A tamper-evident dispensing structure for being sealed to a collapsible pouch having two opposed, flexible web portions sealed to one another so as to define an interior region and so as to define an opening which opens to the interior region and which is adapted to receive a portion of the dispensing structure when the dispensing structure is sealed to the collapsible pouch, said dispensing structure comprising:
- (A) a fitment having
- (1) a body for being sealed to said pouch at said opening;
- (2) a receiver on said body;
- (3) a spout extending above said body and receiver;
- and
- (4) at least one dispensing passage through said body and said spout;
- and
- (B) a lid structure that is molded separately from, and that can be subsequently mounted to, said fitment and that has
- (1) a base for being fixedly and non-releasably attached to said fitment receiver;
- (2) a cap for being sealingly and removably mounted on said spout to occlude said dispensing passage;
- (3) a tear band between said cap and said base;
- (4) a first frangible web connecting said tear band to said base for accommodating complete tearing of said tear band from said base;
- and
- (5) a second frangible web connecting only part of said tear band to said cap to leave said tear band attached to said cap after tearing said second frangible web.
A tamper-evident dispensing structure for being sealed to a collapsible pouch having two opposed, flexible web portions sealed to one another so as to define an interior region and so as to define an opening which opens to the interior region and which is adapted to receive a portion of the dispensing structure when the dispensing structure is sealed to the collapsible pouch, said dispensing structure including at least two components comprising:
- (A) a fitment having
- (1) at least one surface for being sealed to said pouch around a periphery of said fitment at said opening,
- (2) a receiver, and
- (3) at least one dispensing passage through said fitment;
- and
- (B) a lid structure that is molded separately from, and that can be subsequently mounted to, said fitment and that has
