- the invention relates to a rigid receptacle 10, in particular a bottle, in particular a bottle for a cosmetic product such as mascara.
- a rigid receptacle 10 in particular a bottle, in particular a bottle for a cosmetic product such as mascara.
- the receptacle 10 comprises a first layer, called the body of the receptacle 20 and a second layer, called the envelope of the receptacle 30.
- the body 20 has the particularity of defining the neck 22 of said receptacle 10. It comes from the shaping of a preform. It thus presents in itself a certain rigidity.
- the envelope 30 is, in turn, obtained in injected material; it surrounds the body 20. It also has a certain rigidity. It is therefore not a flexible film or a label.
- the envelope 30 is advantageously intended to form or to carry a decoration on its outer wall 32; the inner wall 31 of said casing being in contact with the body of the receptacle 20, more precisely with the outer wall 21 of the latter. This decoration is intended to personalize said receptacle 10.
- the envelope 30 is preferably non-transparent.
- the inner wall 23 of said body 20 defines, for its part, a container for the cosmetic product.
- the neck 22 of said body 20 here comprises a neck 24 having technical forms enabling it to cooperate with, for example, the gripping portion of a mascara brush (not shown).
- Said neck 24 is made in a single layer of material, just like the part 25 forming the bottom of said receptacle 10. This means that the envelope 30 does not cover said neck 24 or said bottom 25 which are mono-materials and which belong audit body 20.

These complementary forms may be counter-forms of the niche type or undercuts type tails. dovetail (not shown). They may be derived from material with said body 20, on the one hand, and with said casing 30, on the other hand.
- the invention also relates to a method for the manufacture of said receptacle 10 and a device for said manufacture.
- Figure 2 is a schematic view of an embodiment of the device for the manufacture of rigid containers such as that described above, in a first phase of manufacture.
- This phase will be called the "injection phase”.
- the device of the invention comprises two injection stations 40, 50.
- the first station 40 injects the envelope 30 while the second station 50 injects a preform 52.
- said device comprises a fixed part 70, serving as a reference , and a movable portion 60 relative to the fixed portion 70.
- the movable portion 60 is configured to be moved in translation in a direction called the opening / closing direction of the device; said direction is referenced X in Figures 2 to 7 and corresponds to the vertical in these drawings.
- the movable portion is provided with a rotating base 62. Said rotating base 62 is capable of performing rotational movements of 180 ° around said opening / closing direction X.
- Said "injection phase” comprises the following steps of the process according to the invention: injection of the preform 52 and injection of the envelope 30. It should be noted that the preform 52 and the envelope 30 are advantageously injected in a single operation, in a single layer of material, directly to their final thickness. These injection steps are preferably performed simultaneously.
- the device of the invention is in said closed position.
- the injection of material inside said first injection station 40 is done here via a first nozzle 41, around a first core 42, between two shells 43, 44 of a first mold, said first mold being closed at the time of injection.
- These two shells 43, 44 are integral with the rotating base 62.
- the rotating base 62 comprises another pair of shells 43 ', 44' forming a second mold.
- This other pair of shells 43 ', 44', also integral with said rotary base 62, is situated diametrically opposite to the first pair of shells 43, 44, and with respect to the hinge axis X.
- the injection of material inside the second injection station 50 is via a second nozzle 57, around a second core 56, between two mold parts 51, 53 and two retaining portions 54, 55, said mold being closed during said injection.
- the injection of material at the first injection station 40 is in a direction parallel to said opening / closing direction X while the injection of material at the second injection station 50 is according to a direction perpendicular to said direction X.
- FIG. 3 illustrates a second phase of manufacture. This phase will be called the "opening phase of the device" during which said movable portion 60 is spaced from said fixed portion 70 in said opening / closing direction X.
- the shells 43, 43 ', 44, 44' being integral with said movable part 60, they move with it when it is translated relative to the fixed part 70.
- the opening - or translation - of the movable portion 60 of the device of the invention causes the release of the casing 30 of the core 42 around which it was injected during the previous phase.
- the preform 52 remains around the core 56 of the second injection station 50 which gave it its shape. Indeed, although the two mold parts 51, 53 of said second injection station 50 open simultaneously to the device of the invention, the two retaining portions 54, 55 come to maintain the preform 52 around the core 56. These retaining portions 54, 55 are located at the opposite end of the one where the injection nozzle 57 of the second injection station 50 is situated. As will be developed below, the said retaining portions 54, 55 are linked to each other. to a so-called central part, 80 of said device. They surround one end of said second core 56.
- FIG. 4 illustrates a third phase of manufacture. This phase will be called the "rotation phase”.
- said rotary base 62 is able to be moved in rotation by an angle of 180 ° around the direction X, when said device is in its open configuration illustrated in FIG.
- the arrow Y indicates this rotation in FIG. 4.
- the two injection stations 40, 50 of the device of the invention being distant from each other, said rotation of 180 ° makes it possible to bring the first pair of shells 43, 44 which contains the envelope 30 which comes to be injected in the vicinity of the second injection station 50.
- said injection station 50 cooperates with the central portion 80 already mentioned.
- Said central portion 80 is located between said fixed and mobile parts 60 of the device. It is in the vicinity of this central portion 80 that the shells 43, 44 are brought after rotation about the X direction.
- Said central portion 80 has four faces, each face comprising a said second core 56 for the injection of preforms such as the preform 52 in the mold 50.
- said cores comprise an air inlet for their air supply in order to blowing the preform 52 after it has been injected in the manner previously described.
- Said central portion 80 is rotatable about an axis perpendicular to said opening / closing direction X. Said perpendicular axis is referenced Z in FIG. 4.
- the retaining portions 54, 55 of the preform 52 remain closed during this movement, as do the shells 43, 44 which form the mold in which the envelope 30 is located.
- FIG. 5 illustrates a fourth phase of manufacture. This phase will be called a "device closure" phase.
- the movable portion 60 is translated in the X direction to bring the device of the invention in the closed position.
- the preform 52 is thus housed inside the envelope 30.
- the device is also in position again for a new injection cycle of a new envelope and a new preform (see “injection phase").
- Figure 6 illustrates a fifth phase of manufacture. This phase will be called the "preform shaping phase”.
- the preform 52 is housed inside the envelope 30, it undergoes a blow and deforms within said envelope 30 to take the form. Said preform 52 then becomes the body 20 of the rigid receptacle 10. In fact, said blowing step allows the plating of said preform 52 against the inner wall 31 of said envelope 30. It should be noted that the envelope 30 is placed in position for the shaping of said preform 52 while the temperature of said envelope is lower than that of its melting temperature, so that said envelope, at that time , is rigid.
- a new envelope 30 'and a new preform 52' are advantageously injected (see “injection phase") in parallel with the shaping step of the first preform 52.
- the retention of the body 20 blown inside the casing 30 is obtained by the retaining means mentioned above whose formation will be provided by the profile given to the molding cavity.
- said retaining means are, among others, the technical forms 26, 27 belonging to the body 20 which cooperate with the abutments 36, 37 of the envelope 30.
- a bonding phenomenon by chemical bonding may occur between the outer wall 21 of the body 20 and the inner wall 31 of the envelope 30. This phenomenon may be added to the retaining means previously mentioned to ensure the maintenance of the body 20 inside the envelope 30. It can also be substituted.
- the body 20 and the envelope 30 in two different materials. If the removal of the material chosen for the injection of the body 20 - for example 2% - and greater than that of the material chosen for the injection of the envelope - for example 0.5%, then the retaining means previously mentioned will be necessary to ensure the maintenance of the body 20 inside the casing 30. Indeed, the body 20 would be made to shrink relatively to the casing 30 and this would cause the separation of said two parts.
- FIG. 7 illustrates the last phase of manufacture. This phase will be called the "receptacle ejection phase”.
- the receptacle 10 is a finished product that must be ejected from the device of the invention.
- the retaining portions 53, 54 move apart to release the area of the preform they previously held and the receptacle 10 can be ejected.
- the zone of the preform hitherto retained by the parts 53, 54 is advantageously the neck 22 of the receptacle 10. They may in particular allow the realization of a net or snap-fastening forms of a plug.
- the ejection movement of the finished part can be done while another preform undergoes the previous phase called “shaping phase of the preform", the device being in the closed position.
- shape phase of the preform the device being in the closed position.
- the central portion 80 will undergo a new rotation of 90 °; the device of the invention is then in the open position, the receptacle 10 of the invention then being brought to the face opposite to the first injection station, with respect to the Z axis.
