A deformable small packaging structure for free-flowing products has a valve-like closure (10) produced by a two-component injection molding process and including a dimensionally stable carrier element (11) and an outer jacket (12) which envelopes the carrier element (11) at least in part and has a flexible squirt-nozzle (16) with slotted openings. The outer jacket (12), in relation to the withdrawn squirt-nozzle (16), has a meander-shaped configuration adjacent to the squirt-nozzle (16). The squirt-nozzle (16), in relation to the withdrawn state, is configured as a pot-shaped recess. The outer jacket (12) has an inner annular flange (17) which engages in a recess of the carrier element (11) and is firmly connected therewith. Further, the outer jacket (12) has adjacent to the inner annular flange (17) a circumferential web (18) which engages in a groove of the carrier element (11) and is also firmly connected therewith.
