Double sealing degree accumulator for use between perfume bottle and product delivering head of perfume distributor, has elevated part forcedly displaced for displacing stop ball in removal direction of stop flange
The accumulator has an axial unit including an axial shouldered element (21) with a corner hole (211) extending axially from a raised top edge of the shouldered element towards bottom. An elevated part (212) is forcedly displaced for displacing a stop ball (134) in a removal direction of a stop flange (1231), so as to realize an opening of a vertical guiding hole (123) of a guiding channel (122) when the shouldered element is turned with respect to an envelope (11) until a predetermined position in which a transversal hole (2111) is maintained in communication with a vertical guiding groove.
