Deux bourrelets épousant l'intérieur de ce tube en forme d'un anneau flexible (19) permettront au second corps FIG. 2 avec également ces même particularités (19) une fois emboîtés l'un dans l'autre et d'empêcher ces deux parties (FIG.1 et FIG.2) de se séparer. The bottom of this cylinder (14) is elliptical in shape and in excess thickness so as to allow better grip. The contour of this ellipse comprises a bead (15) of cylindrical section at its contour. Two pre-prepared clips (17) will serve as safety devices for the control. Two beads matching the inside of this tube in the form of a flexible ring (19) will allow the second body FIG. 2 with also these same features (19) once fitted into one another and to prevent these two parts (FIG.1 and FIG.2) from separating.
21 Ce second corps (11) est d'une forme cylindrique de diamètre inférieur à la FIG. 1, permettant un meilleur cheminement de la FIG. 2 à l'intérieur de la FIG. 1. La FIG. 2 en coupe elle est d'une forme cylindrique creuse dans sa totalité, possédant deux ouvertures parallèles (18) le long du cylindre ainsi que d'un bourrelet flexible (19) épousant en forme d'anneau l'extérieur de ce tube (11), pour empêcher celui-ci de sortir du premier corps (12)(FIG.1), une fois emboîté dans celui-ci, lui-même possédant un bourrelet à l'intérieur(19)(FIG.1). Sur la partie supérieure de la Fla.2, s'adaptera une gomine en caoutchouc FIG. 4 de forme cylindrique ouverte dans son ensemble (10) et renforcée par un joint (8) pour meilleure étanchéité et à son extrémité du haut, une membrane (7) . This second body (11) is of a cylindrical shape with a diameter less than FIG. 1, allowing a better progression of FIG. 2 inside FIG. 1. FIG. 2 in section it is of a hollow cylindrical shape in its entirety, having two parallel openings (18) along the cylinder as well as a flexible bead (19) conforming in the form of a ring to the outside of this tube (11 ), to prevent it from coming out of the first body (12) (FIG.1), once fitted into it, itself having a bead inside (19) (FIG.1). On the upper part of Fla.2, will fit a rubber FIG. 4 of cylindrical shape open as a whole (10) and reinforced by a seal (8) for better sealing and at its top end, a membrane (7).
Au bas FIG. 2, I'ouverture (20) logera la FIG. 3 avec son aiguille (2) la pointe à l'intérieur du cylindre à son extrémité en forme de cône plus ouvert (15) permettra une meilleur fixation de l'embout ( FIG.3) et esthétique de la seringue. At the bottom FIG. 2, the opening (20) will house FIG. 3 with its needle (2) the point inside the cylinder at its end in the form of a more open cone (15) will allow better attachment of the nozzle (FIG.3) and aesthetic appearance of the syringe.
31 Embout cylindrique en forme de capuchon (1) dans lequel sera logée l'aiguille (2) à double pointe. Au bas de l'aiguille sera serti le clips (5) à l'aiguille (2) celle-ci maintenue par une colle porcelaine très fine à l'extrémité de l'embout (1) qui se détériorera lors de la pression du ressort sur le clip (5) de la pression du ressort (3) celui-ci maintenu par la pastille biodégradable (4) elle-même retenue par le clip (5). 31 Cylindrical cap-shaped cap (1) in which the double-pointed needle (2) will be housed. At the bottom of the needle will be crimped the clips (5) to the needle (2) which is held by a very fine porcelain glue at the end of the tip (1) which will deteriorate when the spring is pressed on the clip (5) of the spring pressure (3) which is maintained by the biodegradable tablet (4) which is itself retained by the clip (5).
