FIELD: mechanical engineering; dispensing of product under pressure. SUBSTANCE: proposed device has container furnished with valve for aerosol and made integral flexible barrier member which has outer wall segment terminating in sealing flange. Sealing flange is connected with container between upper part and part of side wall. Inner wall segment is connected with outer wall segment by bend. Central piston part passes from end of inner wall segment distal to bend. Barrier is sufficiently thick and rigid to stand freely before being fitted into container exposed to pressure. Segments of outer and inner walls are made in form of opposite truncated cones forming acute angle when barrier is initially fitted in container. Segment of outer wall is more thick and rigid than then of inner wall. Barrier can be arranged in pipe with similar barriers. EFFECT: provision of discharge of product without leaks from one compartment into the other. 18 cl, 8 dwg
