Abstract

Disclosed is a fitment for insertion into the neck of a container for liquid concentrate that can be opened by insertion of the container into a reservoir. The fitment comprises a substantially cylindrical body comprising an exterior mating surface that can sealingly engage the container and an internal web within the cylindrical body closing the fitment having a fracture zone permitting opening the fitment. The web also comprises a hinged fracture zone defined by a straight hinge portion and a partially circular recess in the web.

Claims

1. A fitment for insertion into the neck of a container for liquid concentrate that can be opened by insertion of the container into a reservoir containing means to open the fitment, the fitment comprising a substantially cylindrical body comprising an exterior mating surface that can sealingly engage the container and an internal web within the cylindrical body closing, the fitment having a generally circular recessed fracture zone permitting opening the fitment;

wherein the generally circular recessed fracture zone is defined by a recessed straight hinge portion and a recessed circular portion and the recessed straight hinged portion is recessed less than the circular portion.

2. The fitment of claim 1 wherein the fracture zone comprises a circular recess.

3. The fitment of claim 1 wherein the recess comprises less than 50% of the web thickness.

4. The fitment of claim 1 wherein the recess comprises less than 35% of the web thickness.

5. The fitment of claim 1 wherein the mating surface comprises a means to attach the fitment to a circular container opening.

6. The fitment of claim 1 wherein the internal web, within the cylindrical body closing the fitment, contains an aperture to vent gas or vapor from the container, the aperture being substantially sealed to the passage of liquid using a hydrophobic flexible web.
