• the tail 30 has a free end zone of circular section ending in a circular edge 31, forming a circular support zone on an area complementary support 31A of the flaps 25A during the tearing of the cover 22.
• the outside diameter of the tail 30 is adapted so that the complementary support area 31A of the flaps 25A intersects the branches 25 in their radially outer part. In the example shown, this zone 31A is substantially tangent to the articulation zones 25B.
• the tail 30 is extended downstream, that is to say towards the top of FIG. 1, by a nose 32 opening towards the outside of the body 12.
• the end piece 14 is traversed longitudinally by a channel 34 fluid flow opening on the one hand upstream, that is to say downwards of FIG. 1, on the free end of the tail 30, and on the other hand downstream on the free end nose 32.
• the fluid flow channel 34 has, near its upstream end, a calibrated orifice 35 which defines the pressure drop of the channel.
• This orifice 35 is connected to the circular edge 31 by a zone 34A of progressively increasing cross section in the direction of the upstream orifice, giving the channel a flared shape.
• the nose 32 has at its base an annular shoulder 36 extended upstream by a skirt 38 surrounding the neck 20. Furthermore, the bottle 10 includes means for positioning the tearing tail 30 of the end piece 14 in the neck 20 in at least two relative axial positions.

• This member is constituted by the cap 16, covering the neck 20.
• This cap 16 comprises frangible means of inviolability and of holding the end piece 14 in the waiting position.
• These means are formed by a removable tamper-evident ring 48 formed integrally with the free edge of the cap 16.
• the junction between the cap 16 and the tamper-evident ring 48 is provided by at least one zone 49 of less tearable thickness, in view of the removal of this ring.

• the cap 16 is then fitted by force and hot on the neck 20 until the annular bead 50 of the ring 48 snaps into the groove 53, which immobilizes it relative to the body 12.
• the bottle is thus obtained 10 pre-assembled ready to be filled.
• the bottle is turned over, and the hollow body 12 is filled by its open rear end 18.
• the bottom of the bottle 10 is closed off by pinching and welding this rear end 18.
• the bottle is then in the state shown in the left half of FIG. 5, in which the end piece 14 is in its standby position. and the cap is locked on the neck 20. It should be noted that in this position, the bottle is sealed and the product contained in the hollow body is perfectly preserved from any contamination.
• the pre-assembled bottle can be made sterile, so that the risk of contamination during filling is minimal.
• the user To remove the cap 16, the user first removes the tamper-evident ring 48. It applies pressure to the cap in order to ensure its displacement in the space freed by the ring 48, until its annular bead 54 snaps into the groove 53, and the end edge of the cap 16 abuts against the seat 26 of the body 12, that of the end piece then facing the shoulder 28. During this movement, radial ribs
• the cover is located on the path of the end of the tail 30.
• this causes the branches 25 of the cover 22 to rupture by pressing the edge 31 on a region of the flap close to the articulation zones 25B, the folding of the flaps 25A around their articulation zone 25B and consequently the opening of the cover 22. Consequently, the communication of the upstream orifice of the channel fluid flow 34 with the interior of the body 12 is ensured.
• the configuration of the cover and of the tail 30 makes it possible to limit the stroke of the end piece 14 necessary to reliably tear the cover.
• the body 12 of the bottle 10 has in known manner a radially deformable structure in order to facilitate the distribution of the product, and the configuration of the fluid flow channel 34 is adapted to ensure drop by drop distribution of the product.
• the central stud 58 closes the downstream orifice of the fluid flow channel 34, in order to avoid on the one hand any leakage of fluid contained in the body 12 and on the other hand any contamination of this liquid when the cover 22 has been torn.
• the base of the cap 16 can be shaped so as to be screwed onto a thread provided on the external surface of the body 12. The perforation of the oper ⁇ cule is then carried out by gripping and rotation of the cap.
• the cover can also present a thinned zone of less mechanical resistance having other geometric shapes, for example a circular shape with a diameter slightly greater than that of the edge 31.
