Abstract
An inverted container has a generally cylindrical depending neck, with a cap 18 having an outer wall 19 which engages the neck and an internal sleeve 20 located within the neck and joined to the outer wall by a connecting wall 21. The internal sleeve 20 defines a recess for receiving the feed tube 34, and a frangible seal 28 is secured to the connecting wall of the cap to cover the recess prior to insertion of the feed tube. To prevent pieces of the seal 28 from being separated if the feed tube 34 is inserted with the seal 28 still in place the feed tube has at least one row of upwardly-projecting puncturing elements 48 which create a controlled rupture of the seal prior to penetration of the feed tube.
