FIELD: transport, distribution.SUBSTANCE: bottle (1) with an open neck (2) contains the first retaining flange (3) located around at least a portion of the neck and a pressure cap (7) fitted on the neck (2). The cap has an outlet with a valve (32) to control flow through the outlet and the second retaining flange (9) located in such a way that when the cap (7) is placed on the bottle (1) the first and the second retaining flanges (3, 9) deviate from each other when they pass and clamp back in place after passing, in this process, a bead (41) of the first retaining flange engages the bead (131) on the second retaining flange to provide reliable retention of the cap on the bottle.EFFECT: invention substantially complicates the cap removal from the bottle by a common user which fact prevents the bottle filling with product incompatible with the batcher.14 cl, 12 dwg |
