• FIG. 1 there is shown a pre-assembled bottle 10 comprising a hollow body 12, intended to receive a sterile fluid product, a nozzle 14 and a cap 16.
• the assembly has a general axis of symmetry XX assumed to be vertical .
• the hollow body 12 has an open posterior and lower end 18 intended for its filling, and a narrowed front and upper end forming a neck 20 capped by the cap 16 and on which the end piece 14 is fitted.
• the body 12 further comprises a transverse cover 22 so as to hermetically seal the neck, arranged back with respect to the outlet orifice thereof.
• the cover 22 has a relatively large thickness over most of its surface and comprises a zone 24 of less mechanical resistance weakening said cover to make it tearable.
• the zone 24 of less mechanical resistance has the shape of a star with four branches, such as 25, regularly distributed in the cover 22 so as to form a cross. These branches are produced by means of a strong thinning of the corresponding zones of the cover 22.
• the branches 25 of the weakening star delimit two by two in the cover 22 of the retractable flaps, such as 25A, of width radially increasing in the direction of the periphery of the cover.
• the cover thus has four triangular shaped flaps. It further comprises four articulation zones, such as 25B, located near the periphery of the cover 22 and each corresponding to an articulation zone for one of the flaps 25A.
• the articulation zones shown in dotted lines in FIG. 2, connect the radially outer ends of two consecutive branches 25 in pairs.
• the body 12 further comprises an annular seat 26 and a coaxial shoulder 28, of smaller diameter, closer to the neck 20.
• the annular seat 26 is intended to receive a portion of the cap 16 , as will be described in detail later.
• the bottle 10 also comprises means for perforating the cover 22. According to the embodiment shown, these means are constituted by a member for pushing the flaps 25A formed by the end piece 14, fitted into the neck 20.
• the end piece 14 is axially movable in the neck 20 between a standby position and an active position of tearing of the cover and has a tail. 30 for tearing this cover 22 extending the end piece 14 in the neck 20.
• the tail 30 has a free end zone of circular section ending in a circular edge 31, forming a zone of circular support on a complementary support area 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.
• these means consist of means of snap-on success- sifs formed on the one hand by a crown of notches 40 incli ⁇ born upward, projecting from the internal face of the skirt 38, and, on the other hand, by two axially offset flanges 42 and 44 formed on the surface external of the neck 20, each defining an upper snap-on ramp for the notches 40 and delimiting two respective grooves 45 and 46.
• the shoulder 36 further comprises a set of lights, such as 47, intended to facilitate the release of the notches 40.
• the bottle 10 further comprises a member for operating the end piece 14.
• 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 ring 48 has an internal annular bead 50 cooperating with a latching collar 52 formed on the external face of the neck 20 and defining a groove 53 below it.
• the cap 16 comprises a second annular bead 54 similar to the bead 50 of the ring 48 and intended to cooperate with the same groove 53 of the neck 20. It further comprises, near its upper bottom region, a set of ribs radial, such as 56, forming bearing surfaces, intended to cooperate with the shoulder 36 of the endpiece 14, and its bottom internally comprises a central stud 58 closing the downstream orifice of the fluid flow channel 34 of end cap 14.
• the body 12 is first produced by injection of a plasti ⁇ material, in one piece, with its open rear end 18 and its closed neck 20 by the cover 22 weakened by the star 24 and formed integrally with the neck 20.
• the end piece 14 and the capu ⁇ chon 16 are produced separately by injection of a plastic material.
• the end piece 14 is then engaged in the neck 20 so that the row of notches 40 snaps into the upper notch 45.
• 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 use of this bottle is as follows. To remove the cap 16, the user first removes the tamper-evident ring 48.
• 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 channel of fluid flow 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.
