Abstract

Bottle assembly and valve assembly Abstract A bottle assembly is provided, comprising: a bottle having an end portion including a first detent formation; and a collar having a second complementary detent formation. The collar is configured to be deformed by application of force only in a direction towards the bottle such that its radius expands locally in the vicinity of the second complementary detent formation as the second complementary detent formation slides over the first detent formation such that the collar snap fits to the end portion by engagement of the detent formations. The end portion comprises a neck portion and the direction towards the bottle is a downward direction. The first detent formation has at least one open side permitting the collar to be uncoupled from the end portion when the collar is rotated with respect to the end portion.
