    专利说明:

    [0001] The present invention relates to a molding assembly and a method of manufacturing a syringe body. Syringes are well known in the state of the art. These devices comprise a substantially cylindrical shaped body, receiving on one side a needle cannula, to pierce the injection site and distribute a fluid in said injection site, and provided on the other side of a plug piston, which at rest maintains the product to be dispensed into said body and which in use slides sealingly in said body to dispense said fluid through said cannula.
    [0002] The assembly of a cannula on a syringe body is a crucial step in the manufacture of syringes. The cannula must be accurately positioned and then attached to the syringe without being damaged. The cannula must be aligned with the central axis of the syringe. The cannula should also be attached to the syringe sufficiently strongly to withstand regulatory requirements. The cannula can be inserted in a snug fit into the preformed syringe body. This implementation is difficult to control, especially with small diameter cannulas. The cannula can also be attached to the syringe body by an adhesive. However, it is generally undesirable to use such an adhesive to attach a cannula to a syringe because the adhesive may contain toxic chemicals that could seep into the contents of the syringe, which could disrupt the effectiveness and / or stability of the contents of the syringe. In some cases, especially when the body is made of synthetic material and not glass, the cannula can be assembled on said body by overmoulding, that is to say by injection of the syringe body on said cannula, which allows in particular to avoid the use of an adhesive, and to guarantee a resistant fixation. EP2229197 and WO2012150897 disclose molding assemblies and methods of manufacture of this type, including a forceps for the cannula and an injection mold of the syringe body on said cannula. These molding assemblies used to perform this type of overmolding method, however, have drawbacks. Thus, in the document EP2229197, the opening and closing of the clamp are correlated with the opening / closing of the mold. This clamp thus makes it possible to hold the cannula in the mold during the injection but does not make it possible to route the cannula towards the mold, since outside the mold the clamp is open and therefore the cannula is not maintained. This system is therefore a maintenance system only. Other means must therefore be implemented to position the cannula in the housing of the mold, such as a robot, which complicates the assembly. In WO2012150897, the gripper system consists of two sub-parts, each sub-part being integral with a half-mold. This description corresponds to a mold in two half-shells. In this case, the clamp system is therefore also only a system for holding the cannula during the injection, and other means must be implemented to position the cannula in the mold housing. Furthermore, with a half-shell molding, there is a risk of occurrence of molding defects (infiltration, deformation) at the junction of the two shells and in particular at the hub of the syringe receiving the cannula and on which a needle guard will have to seal. There is therefore a risk of loss of tightness. It is an object of the present invention to provide a molding assembly and a method of manufacturing a syringe body which does not reproduce the aforementioned disadvantages. The object of the present invention is in particular to provide a molding assembly and a method of manufacturing a syringe body which makes it possible to reduce the transfer steps of the cannula, thereby in particular reducing the risk of damaging the cannula. The present invention also aims to provide a molding assembly and a method of manufacturing a syringe body that limit exposure of the cannula to external contaminations. It is also an object of the present invention to provide a molding assembly and a method of manufacturing a syringe barrel which improves the positioning accuracy of the cannula in the mold during molding.

These and other features and advantages of the present invention will become more apparent from the following detailed description, with reference to the accompanying drawings, given as non-limiting examples, and in which: FIGS. 1A and 1B are views respectively in perspective and in cross-section of a molding assembly according to an advantageous embodiment of the invention, in the closed position of said molding assembly; FIG. 2 is a detailed cross-sectional view of the clamp in FIG. FIG. 3 is a cross-sectional view of the forceps in the open position, with a cannula, FIG. 4 is a view similar to that of FIG. 3, with the clamp in the closed position, FIG. FIG. 5 is a cross-sectional view of the clamp in the closed position containing a cannula, with the clamp disposed outside the mold, FIG. 6 is a cross-sectional view of the mold in the open position, with the clamp in the closed position, with cannula, FIG. 7 is a view similar to that of FIG. 6, with the mold in the closed position, FIG. 8 is a view similar to that of FIG. FIG. 9 is a view similar to that of FIG. 8, after injection of the syringe body onto the cannula, with the clamp in the open position, and FIG. a view similar to that of Figure 9, with the mold in the open position. In the following description, the terms "axial", "radial" and "transverse" refer to the longitudinal axis of the cannula in the mold unit, i.e. the vertical axis on Figures 1B and 2 to 10. The terms "proximal" and "distal" refer to the cannula. The invention relates more particularly to the manufacture of a syringe body 10 provided with a cannula 20, said syringe body 10 having a cylindrical portion 11 forming a reservoir, and a hub portion 12 on which is fixed said cannula 20 The invention will be described hereinafter with reference to a complete cycle of the molding assembly, referring to the molding of a syringe body 10 on a cannula 20. It will be understood that the molding assembly may comprise several subsets operating simultaneously.
    [0010] The molding assembly comprises at least one mold unit 100, each mold unit 100 having a first mold portion 110 and a second mold portion 120 axially movable relative to said first mold portion 110 between a first and second mold portions. opening and closing position. In this closed position, said first and second mold portions 110, 120 define therebetween a mold cavity 130, and a core 140, located in said mold cavity 130, defines the shape of said syringe barrel 10. molding assembly also comprises at least one cannula clamp unit 200, each clamp unit 200 having a clamp 210 movable between an open position, into which a cannula 20 can be loaded into a proximal axial end of said clamp 210, and a closed position, wherein said cannula 20 is held in said clip 210. Said clip unit 200 is axially movable relative to said mold unit 100 to arrange a cannula 20 into said mold cavity 130. Displacement of said clip 210 between its open and closed positions is independent of the axial displacement of said first and second mold parts 110, 120 between said open positions. re-closing said mold unit 100. Each clamp unit 200 includes an actuating member 220 axially movable between a closed position and an open position, said actuating member 220 being adapted to move said clamp 210 between said closed and open positions. Advantageously, said actuating element 220 comprises a frustoconical axial proximal end 221 cooperating with a distal axial end 211 of said clamp 210. This distal axial end 211 advantageously comprises a conical hollow shape complementary to said frustoconical proximal axial end 221 of said element. actuation 220, so that an axial displacement of said actuating element 220 causes a radial displacement of said clamp 210 between said closed and open positions. In particular, when the actuating element 220 advances axially in said clamp, its frustoconical axial end end 221 will slide into the complementary conical hollow shape of said distal axial end 211 of said clamp 210, which will cause the radial spacing and thus the opening of said clamp 210.
    [0011] Advantageously, said clamp 210 is elastically biased towards its closed position. Thus, when the actuating element 220 moves axially out of said clamp, it automatically closes. A controller 230, such as a jack, cooperating with said actuating member 220 of said clamp unit 200 is provided for moving said actuating member 220 between its closed and open positions. The actuation of this control member 230 is independent of the opening and / or closure of the mold unit 100. The molding assembly further comprises a cannula loading unit 10 adapted to load a cannula 20 in a clamp unit 200. This cannula loading unit 300 may be of conventional type. In the example shown in the figures, the molding assembly comprises two mold units 100 and two cannula loading units 300 transversely offset, and four gripper units 200 arranged in pairs on a pendulum arm 250, in particular pivoting . Thus, while the two cannula loading units 300 load a respective cannula into two clamp units, the two mold units 100 each mold a syringe body 10 around a cannula 20. Then, the pendulum arm 250 rotates, and brings on the one hand the two clamp units 200 loaded with cannulas 20 facing the two mold units 100, and on the other hand brings the other two clamp units facing the two cannula loading units 300. Advantageously four control members 230 are provided for separately and independently controlling the four clamps 210. This advantageous implementation is however not limiting, and other configurations are conceivable. Advantageously, the first mold parts 120 of the two mold units are formed by one and the same plate. Advantageously, the second mold parts 120 of the two mold units are also formed by the same plate.
    [0012] It should be noted that the numbers of mold units 100, clamp units 200 and cannula loading units 300 may be any, the above example not being limiting. Advantageously, each clamp 210 comprises a recess 215 5 receiving in all positions the piercing tip 21 of the cannula 20. Thus, no stress is exerted on said piercing tip 21, nor during the loading of said cannula 20 in said clamp 210 by said cannula loading unit 300, neither during the movements of said clamp 210, nor during the molding of said syringe body 10 around said cannula 20 by said mold unit 100. Advantageously, each mold unit 100 comprises a positioning member 150 cooperating with the axial end of the cannula 20 opposite said piercing tip 21. This ensures accurate positioning of said cannula 20 in said mold unit 100 during molding of the syringe body 10, without the risk of damaging the piercing tip 21. In this respect, it is advantageous that the clamp 210, in the closed position, allow a slight axial displacement of the cannula 20 with respect to the clamp, especially by sliding. A manufacturing cycle of a syringe body will be described hereinafter with reference to the figures, to illustrate the manufacturing process. The clamp 210, closed in FIG. 2, is opened by means of an actuating element 220 of said clamp unit 200, said actuating element 220 being controlled by a control member 230, such as a jack. The open position of the clamp is visible in FIG.
    [0013] A cannula 20 is then loaded into said open clamp 210 by means of a cannula loading unit 300. Said clamp 210 is then closed on said cannula 20, as shown in FIG. 4. Then, as shown in FIG. 5 said clamp unit 200 is axially remote from said cannula loading unit 300, said closed cannula clamp 20 being disposed opposite a cannula loading unit 300.
    [0014] Said clamp unit 200 containing said cannula 20 is then moved laterally to face a mold unit 100. Then said clamp unit 200 containing said cannula 20 is moved axially with respect to said mold unit 100 to insert said cannula 5 in said mold unit 100. The position with the closed mold unit 100 containing said cannula is shown in FIG. 7. Synthetic material is then injected into said mold unit 100 to mold said syringe body 10 around said cannula 20, as visible in FIG. 8.
    [0015] After molding, said clamp 210 is opened by means of said actuating element 220 of said clamp unit 200, said actuating element 220 being controlled by a control member 230, such as a jack, as shown in FIG. 9. This controller 230 may be different from that having opened the clamp 210 for loading the cannula. Thus, said step of opening the clamp 210 to load the cannula 20 can be performed by a first control member 230, and said step of opening said clamp 210 after molding said syringe body 10 can be performed by a second body member. control 230, said first and second control members 230 being actuated independently of each other, and independently of movements of said mold unit 100. Finally, said mold unit 100 is opened to eject said syringe body 10 molded around said cannula 20, as shown in Fig. 10. The molding assembly is then ready for the next cycle.
    [0016] As explained above, the molding assembly shown in the figures enables two syringe bodies to be manufactured simultaneously. Advantageously, the step of axially displacing said clamp unit 200 containing said cannula 20 with respect to said mold unit 100 to insert said cannula 20 into said mold unit 100 is carried out as follows: mold 100 is firstly opened by axially moving said second mold part 120 relative to said first mold part 110, - said clamp unit 200 is inserted into said second mold part 120, as can be seen in FIG. 6, and - said mold unit 100 is closed by axially moving said second mold part 120, together with said clamp unit 200, with respect to said first mold part 110. Alternatively, this step of axially moving said clamp unit 10 200 containing said cannula 20 with respect to said mold unit 100 for inserting said cannula 20 into said mold unit 100 can also be performed in the manner next: - said mold unit 100 is first closed by axially moving said second mold part 120 relative to said first mold part 110, and - said clamp unit 200 containing said cannula 20 is moved axially with respect to said mold unit 100 closed to insert said cannula 20 into said mold unit 100. Advantageously, said at least one cannula loading unit 300 is attached to said second mold part 120. This makes it possible to correlate the displacements of said unit 300 cannula loading with the movements of said second mold part 120, and thus improve the positioning accuracy of the cannula 20 in the clamp 210. The present invention therefore allows in particular to provide the following advantages: - none contact occurs with the piercing tip 21 of the cannula 20 throughout the manufacturing process; this avoids any risk of damage to said piercing tip; the number of cannula 20 transfers is reduced: the cannula is loaded into the forceps, and then it remains held in this forceps until the end of the molding process of the syringe body 10 around the cannula 20; this also makes it possible to limit the risks of damage to the cannula, in particular by limiting the contact with dirt or particles; as a result, exposure of the needle to external contaminations is severely limited; the cannula can be very precisely positioned in the mold unit at the time of molding of the syringe body. Although the present invention has been described with reference to an advantageous embodiment, it is understood that various modifications are possible for those skilled in the art without departing from the scope of the present invention as defined by the appended claims.
