- transfer molding devices in which the molded part is transferred, after cooling, via a robot for example to another molding cavity to be overmolded.
- This type of device makes it possible to obtain molded products that include several materials or even several colors.
- this type of device that can implement robotic systems, is expensive.
- this device requires two molded molding cavities, and therefore has the disadvantage of being spatially bulky.
- this device involves moving the molded part before overmolding which may damage, at least superficially, the molded part. To avoid this risk of degradation, the cooling time of the molded part after molding requires elongation which implies a loss of time and therefore a decrease in the productivity of this type of process.
- the molded part is, via the rotary plate, translated to another mold cavity in order to be overmolded.
- This device has the advantage of not involving the displacement of the molded part but only that of the turntable which substantially reduces the risk of deformation before overmolding.
- this type of device is very expensive and space-consuming and the satisfactory adjustment of the rotation of the plate is difficult to implement.
- the molding cavity is partially open so as to leave a space which will be filled by the overmoulding material.
- This device is compact because it requires only one molding cavity per room molded but the molding by this type of device has a low productivity.
- the invention therefore aims to provide a method of molding and assembly of parts which avoids the aforementioned drawbacks and which allows molding having a great ease of implementation and significant productivity.

- said molding cavities are arranged relative to each other so that the relative movement to assemble said first piece and said second piece is a translational movement.
- the first part is immobile and the second part slides, advantageously pushed by a stripping device, to the first part until the crampon comes fully snap on the hooking hole.
- the first and second parts are then mechanically secured to one another by snapping. They then form a set preferably consisting of two materials, which may be of different colors.
- the materials that can be used in the present invention are, for example, all plastics having characteristics close to those of polypropylene.
- the method according to the invention takes place in a single molding device and involves only conventional molding material that is to say a multi-cavity injection mold and a press.

- the screw assembly allows the user to reload the container comprising a dispenser head TDl 'with the product to be dispensed.
- the snap-in assembly with the presence of tamper evidence is, for the user, evidence, before first use, of the integrity of the contents of the container having a dispenser head TDl '.
- peripheral wrapping skirt 8 conceals harmoniously the internal elements of the dispenser head TDl 'ensuring the attachment and sealing by adapting to the general shape of the container.

- a retaining screw of the drawer guide 912 mechanically secures a sliding guide 913 and a stripper plate 914.
- the stripper plate 914 is mechanically secured to a stripper 901 by the combined action of an assembly ring 915 and the cooperation of a shoulder 901b of the stripper 901 with a stop 914a of the stripper plate 914.
- the rear part of the drawer mold 903 is guided in translation by the cooperation of a shoulder 913b of the sliding guide 913 with a stop 904a of circular portion 904 of the drawer mold 903.
- the rear portion of the drawer mold 903 is also guided. in translation by guiding devices (not shown) arranged in the transverse orifices 924. According to FIG. 16, the molding cavity 931 of the operculum
- I is defined by the lower wall of the upper molding core 902 (for molding the upper face of the first anchoring portion
- the molding cavity 932 of the nozzle 2 is defined by the lower wall of the circular portion 904 of the slide mold 903 (for molding the upper face of the nozzle 2 and the outer face of the peripheral skirt 8), by the upper wall of the outer core 908 of the lower molding core 907 (for the molding of the space between the surrounding peripheral skirt 8 and the inner peripheral skirt 7) and by the upper wall of the inner core 909 of the lower molding core 907 (for molding the space between the inner peripheral skirt 7 and the sealing skirt 6 and in particular the molding of the abutment 72 and the central lower face of the nozzle 2).
- the same material, or even different materials, possibly of different color, is (are) injected into the center of the molding cavities 931 and 932 by the upper injection channels 918 and lower 919 respectively.
- each portion of the slide mold 903 (composed of a lower circular portion 904, a molding upper 905 and a holding upper 906) is translated in the opposite direction of the molding cavities. 931 and 932.
- the transverse traction means of each part of the drawer mold are not shown in FIG. 15.
- the rear part of the slide mold 903 is guided in translation by the cooperation of the shoulder 913b of the sliding guide 913 with the stop 904a circular portion 904 of the drawer mold 903.
- the rear portion of the drawer mold 903 is also guided in translation by guide devices (not shown) disposed in the transverse holes 924.
- the space between the mouthpiece 2 and the cover is free.
- the assembly can then take place.
- a press (not shown) is actuated and induces an upward translation movement (by not shown intermediate parts) to the inner core 909 and the intermediate sleeve 1000 and the stripper plate 914 which, secured to the stripper 901 pushes the stripper 901 upwards.
- the vertical translation movement is transmitted to the endpiece 2, by the cooperation of the radial abutment 901a of the stripper 901 with the lower face of the peripheral wrapping skirt 8 and the upper end of the inner core 909 with the face internal sealing skirt 5.
- the nozzle 2 then slides in the direction of the cap 1 until the cleats 3 and 4 come into engagement with the attachment holes 21 and 23 respectively.
- This assembly step is made possible by the fact that the cover 1 is immobilized by the upper end of the retaining rods 916 and 917 and by the upper end of the ejection pin 921.
- the outer core 908 of the lower molding core 907 remains stationary while the press is actuated.
- the upward vertical translation of the inner core 909 and the intermediate sleeve 1000 relative to the outer core 908 which itself remains fixed, allows the molding of the molded parts by the outer core 908.
- the vertical thrust upwards by the stripper 901 is continued after assembly of the nozzle 2 and the lid 1, so as to eject the dispenser head TD1 assembly and the release of the stop 72.
- the various elements constituting the molding device are replaced in the previously described molding arrangement in order to reconstitute the molding cavities 931 and 932 for a new molding / assembly step.
- Dispenser heads according to the variant of the first embodiment TD1 ', according to the second embodiment TD2 or any other product comprising at least two molded parts which are assembled in a similar molding device are within the scope of the present invention. .
- molding devices or distributor heads having structural variants are also within the scope of the present invention.
