摘要：
The invention relates to a capsule comprising a hollowtubular body (2), a hollow cap (3) telescopically engageable on the body(2), the body (2) and the cap (3) defining an inner volume therebetweenand being provided with complementary snap-fit means (12, 21 ) forlock-ing the cap (3) on the body (2) in the fully closed final position, thecom-plementary snap-fit means (12, 21 ) comprising a locking ring (12)formed on the body (2) and a complementary ridge member (21 ) formedon the cap (3), at least one air-vent (14) formed as an axial recess on theouter surface of the body (2) and suitable for ensuring fluidcommunica-tion between the inner volume and the atmosphere. The capsule (1 )isconfigured such that, in the fully closed final position, the inner surface ofthe cap (3) fits on the outer surface of the body (2) over a continuouscir-cumferential contact section (33) and the air-vent (14) axially extendsfrom the open end (5) of the body (2) toward the contact section (33), soas to provide fluid communication between the inner volume and theat-mosphere over the whole range of engagement positions, excluding thefully closed final position wherein the inner surface of the cap (3)sealing-ly engages the outer surface of the body (2) over the contact section(33).Application to capsules for liquid dosages.
