The inventive pouch consists of: an upper rigid part (3) comprising a neck opening (5) and a lower deformable flexible part (4) which is associated with means for dispensing the aforementioned products without the intake of air into the pouch, said two parts (3, 4) being articulated to one another such that the top of the inner wall of the lower part (4) is pressed against the inner wall of the upper part (3) upon retraction of the pouch (2). Moreover, the lower flexible part (4) of the pouch comprises a constriction (7) forming a bellows which is shaped such that it folds onto the inner wall of the upper rigid part (3) upon retraction, said constriction (7) being formed in the upper part of the flexible pouch (4).
