Abstract

The invention concerns mould devices (A-B) and (C-D) on carousels 'ONE' and 'TWO' for simultaneous injections of matching elements, for example: a 'single-piece closure' and a 'suction straw'. The shell moulds (A-B) and (C-D) are fixed on two arms arranged on the diameter of each carousel, separated by a hub, rotating with four breaks offset on separate planes, with a converging point on their tangents, corresponding to a common alternating break, (two) and (one). Located at each of the breaks (one), with fixed stations: in low position one mould vertically mobile upwards, in high position a vertical injection station mobile downwards. The moulds (A-B) have a unilateral injection point (13a) corresponding to the horizontal injection station located in the surface area of the carousel 'ONE', enabling said common break, and by translation, to make integral by overmoulding the matching elements.

Description

Mussels in merry-go-rounds, mobile molds with fixed positions, simultaneous injections before joining, additional elements such as a monobloc closure-Suction straw for capacity with drinks.

Since French Patent No. 98.09983 of August 4, 1998,

PCT / FR / 01925 (WO 00/07795), it is known that the internal and projecting tube which constitutes the "suction straw" of a bottle-torch, according to French Patent No. 96.08141 of June 28, 1996 (PCT / FFV97 / 01162 (WO 98/00280) passes through the interior of the neck, secured to the internal wall of the latter.

According to this same French patent of August 4, 1998, it is also known to use a non-removable closure device, extended by a removable cap, to simultaneously seal the neck and the orifice of the projecting part of the tubing of a bottle. - torch Until today, this closure device irremovably closes the neck, and in a removable manner the projecting part of the internal tubing of the bottle-torch in which it is integrated, making this closure device and this type of interdependent. Bottle-torch, which limits its scope. The present invention allows, among other things, an extension of use to the capacities coming from extrusion blow-molding, and which cannot, for obvious technical reasons, have an internal and protruding tube, without the obligation to stamp longitudinally, in a mold with shells the extruded parison (See French Patent No. 1453848 of March 24, 1965, and its Additions No. 88.270 of June 5, 1965, No. 93.060 of October 22, 1966 and No. 95.492 of March 18, 1968). As well as the capacities obtained by the injection-blowing of a preform of the "test tube" type which, for different technical reasons, cannot have an internal and projecting tube, (See the French Patent of June 28, 1996) obstacle to the elongation of this preform if the thermoplastic material injected is a Polyethyleneterephthalate (PET) that is difficult to stretch to lengthen and thin it (Bi-Orientation).

Unlike his French patent of August 4, 1998, where the tubing injected into what becomes the body of the bottle, is made integral with the internal wall of its neck, the applicant in the context of this invention in particular and simultaneously injects, from rides, the non-removable closure extended by a removable cap, with a particularly injected tubing, which includes arrangements which complement those of the non-removable part of the above-mentioned closure, which allows them make it integral by molding in particular. The various solutions shown in the Figures in support of the present invention are capable of being combined with one another and can be applied equally to an assembly intended for a capacitor containing a flat, milky or even carbonated drink; which leads the applicant to ignore Figures, in particular as regards the other possible arrangement of the projecting edges 3 ', those used being sufficient to understand the present invention.

The present invention makes it possible, among other things, to install a tubing longer than the interior of the capacitor, with a material having qualities of flexibility, which can bend by reaching its bottom. As soon as it is closed, it becomes a "bottle-torch" , with the following advantages: a) - These devices can be used interchangeably with capacities obtained by injection-blowing, extrusion-blowing, in plasticized, metallic cardboard, as well as in glass. b) - These devices allow the use of a different thermostatic material for the tubing and for example of the Polyolefin family, than that possibly used for obtaining the capacity, the only criteria to be retained are the compatibility of this tubing, with the drink in which it is immersed; as for the projecting part of this tubing, it is protected from the external environment by the removable cap of the non-removable closure device which can also be made of a material of the same family for example, meeting the same criteria. c) - These devices do not intervene in the technique chosen for obtaining the capabilities, therefore the implementation equipment which does not have to undergo any modification. d) - These devices make it possible to release part of a specific production, to transform it into "bottle-torches" without repercussions on its cost, and without disturbing its production rate. For convenience in the explanations in support of the Figures chosen for the present invention, the applicant will designate all of the internal and projecting tubing simply by: "the suction straw"", it will be the same for the irremovable closure extended by a removable cap, which will be simply designated by: "the one-piece closure".

For the references of the constituent elements, both of the molds, of "the suction straw" or of "the one-piece closure", the applicant will use, as far as possible, the same references as those used in the two French patents of June 28, 1996 and August 4, 1998 already mentioned.

For the use of cooling techniques and internal arrangements of certain molds, the applicant will mention this, by referring to its patent PCT / FR / 97/01162 of June 30, 1997.

Certain components of the molds, in contact with the injected material, may be coated with a non-stick material such as, for example, Polyetetrafluoroethylene, according to its French Patent No. 1,505,492 of January 15, 1963.

In the context of the present invention, the applicant claims the applications requiring the use of two roundabouts allowing simultaneous injections of complementary elements and made integral, also in many industrial fields, such as for example in the electrical, electronic or even industry. and for example that of the automobile, avoiding or limiting assembly operations.

According to the present invention, the applicant uses a double rides "ONE" and "TWO", shown schematically in Figures 1 and 2 to explain the manufacturing process which includes four phases.

Each roundabout has on its diameter two arms, separated by a central rotation hub, on which are installed, at least one shell mold A and B for the roundabout "ONE" and C and D for the roundabout "TWO", preferably in steel like the roundabouts, their rotary circuits are carried out with four pauses at offset locations, on separate planes, but have a point of convergence on their tangents. The arms of each carousel are characterized to be, at any of the four breaks, always in a perpendicular position opposite the arms of the other carousel This feature allows these shell mussels, having a common break never to be there at the same time, this being used alternately by the molds of each carousel. The direction of rotation of the rides is arbitrary and does not affect the scope of the invention.

The clashing of the shell molds shown takes place in the direction of rotation of the roundabouts, but can also be carried out perpendicular to the latter; which will lead to the arrangements originally dug from the confronting faces of the shells of the mussels, from being from the rear face of or one of these shells, and in the axis of their confrontations.

Elements with fixed stations depending on the "UN" riding school at the pausel. a vertical injection station (not shown) located in the high position capable, with a jack, of descending to the injection point 13 located on the upper confrontation line of the shell mold A (or B), according to Figures 6 or 11.

- in the pausel, but located in the low position (not shown), the male unitary mold 7a, characterized to have a female part, is capable of moving vertically with a jack, to come into confrontation by its upper face, with the face lower of the molds A (or B), by setting up an injection space which defines the "Closure-monoblock", according to the same Figures.6 or 11. - at Pause2. in the middle position (not shown) in the area of revolution of the carousel, a horizontal injection station and perpendicular to the passage of the A or B molds. Capable with a similar cylinder, to come to the injection point 13a consisting of a rectilinear cannula, preferably made of steel, housed in arrangements hollowed out unilaterally on the facing faces of the shells 5a 5a 'of the aforementioned molds, this cannula has its internal projecting orifice which is temporarily closed by the male mold 7a, according to the Figures 6 and 11. Fixed Station components dependent on the "TWO" ride

- at the pausel. a vertical injection station, preferably double, located in the high position (not shown), capable, with a similar cylinder, of descending to the injection points 13 arranged on the upper faces of confrontation of the shells 5 and 5 'of the molds C or D, according to Figures 3 and 13.

- at the Pausel but located in the low position (not shown), a female mold 7 characterized to have a male part, capable of moving vertically with an identical jack, to come into confrontation by its upper face, with the lower face of the molds C or D according to the same Figures 3 and 13 by providing an injection space between them, which defines the "suction straw"

SIMULTANEOUS INJECTION PROCESS Merry-go-round ONE. Phase 1 At the injection break 1, the mold A, facing shells, receives the male mold 7a rising from its low position, while the mold B is at pause 3. After the injection of the "one-piece closure" the male mold 7a returns to its low position which frees the internal orifice of the horizontal injection point (13a), leaving the injection product between the shells still facing the mold A.

Merry-go-round TWO.Phase 1

At the injection break 1, the mold C, facing shells, receives the female mold 7 raised from its low position, while the mold D is at pause 3. After injection of the "suction straw" for drinks flat or milky, the female mold 7 returns to its low position, but with the "suction straw", to allow the shells 5 and 5 'of the mold C which have a part to be inserted into the female mold 7 to not no longer be in confrontation While for these same molds C and D in the same position, but for "a suction straw" for carbonated drinks, it is first necessary that the shells 5 and 5 'cease their confrontation to be able to bring the mold female 7 in its low position with the "suction straw"; some elements used for injection may be coated with a non-stick material. Merry-go-round ONE. Phase 2

From break 1, mold A goes to break 2, while mold B from break 3, with its open shells, goes to break 4. Roundabouts ONE and TWO. Phase 2 In addition to mold A of the Armory UN, mold C of the armory

TWO leaves pause 1 for pause 2, while mold D goes to pause 4. This simultaneous translation allows the female mold 7 of the carousel DEUX in stationary position at pause 1, still with the "suction straw" , go back to the high position and enter the mold A of "one-piece closure", limited by the confrontation of its upper end face, with the lower end face of mold A of the ride UN, which allows from the fixed station injection located in its rotation area, inject plastic through the horizontal injection point 13a, through the hole obtained in the skirt, around the projecting orifice, of the rectilinear cannula which constitutes the horizontal injection point (13a), which is no longer blocked, from the start of the male mold 7a. Under certain circumstances, the additional elements injected can also be made integral, in addition to overmolding, by self-welding. Merry-go-round UN, Phase 3 From pause 2. mold A, with the "one-piece suction straw closure" assembly, goes to pause 3, while mold B which has left pause 4 comes to pause 1 injection, to restart the process performed by mold A in Phase 1. Roundabout TWO. Phase 3 From pause 2, mold C goes to pause 3, with the shells in the confrontation position again, while mold D leaves pause 4 and comes to injection pause 1, to restart the process made by mold C in Phase 1.

Handle ONE and TWO. Phase 4 While mold D, open shells, of carousel TWO leaves pause 1 for pause 2, which allows female mold 7 of the carousel

TWO in a fixed position at pause 1 with "the suction straw", to repeat the process already carried out with mold C in Phase 2, the latter going to the pause 4. Simultaneously mold B leaves pause 1 to come to pause 2 of ride UN, and performs the same process as mold A, when it was at pause 2. As for mold A, it leaves pause 3 to come to break 4 where its shells open to release the "one-piece closure - suction straw" assembly to direct it by a translation device (not shown) to the packaging and closing stations with the protections of hygiene which are essential and which are multiple and known.

For the different movements described with the rides ONE and TWO according to the invention, the applicant takes account of the longest injection cycle, so that the speeds of rotation of the rides which may be different, make the breaks in the molds A and B, during their injection collaboration with the male mold 7a, or the female mold 7, as well as for horizontal injection. To do this, we will automate and regulate the manufacturing cycles using a computer, as well as monitoring by thermoregulator, injection temperatures and cooling circuit, displayed on a screen with control panel. , according to a known and used technique, in particular in the injection-blowing manufacture of capacitors from preforms, both in the hot cycle and in the cold cycle. The horizontal injection point 13a is constituted by a rectilinear cannula, preferably made of steel (not shown). Longitudinally superior to each of the semi-cylindrical half-tunnels dug unilaterally on the front edge of the shells 5a 5a ', according to the technique described in the French Patent of June 28, 1996, so as to form in confrontation a cylindrical tunnel, taking into account the outside diameter of this cannula, which is arranged in the bottom of one of the aforementioned half-tunnels, the assembly is welded preferably by laser; during the confrontation of the shells 5a 5a ', which must be flawless, the other half-tunnel of the other shell, comes to fit around the other longitudinal half of the cannula, and form a tunnel whose l the internal projecting orifice is closed by the presence of the male unitary mold 7a, by creating a vacuum in the injection space of the skirt of the "monoblock closure", caused by the presence of this part of the cannula around this skirt which then has a hole, which allows after replacing the male mold 7a by the female mold 7, an injection through the hole (not referenced) of this skirt, which will have its internal face clogged at the end of injection.

The removable cap of the irremovable closure according to the French Patent of August 4, 1998, comprises two vertical edges projecting 3 ', obtained by arrangements hollowed out on the facing faces of the shells 5a and 5a'. In the context of the present invention, the edges 3 'will come from two vertical trenches, hollowed out identically in the bottom of each of the shells 5a and 5a', perpendicular to their confrontations, so that they do not form obstacles to their openings, given their relatively large vertical outgrowths. For the ease of the drawings and the clarity of the Figures, the edges 3 ′, which have no influence on the devices relating to the molding of the complementary elements making it possible to make them integral, are shown as those of the above-mentioned patent, then that these edges 3 'should be represented on the edge by vertical dotted lines, by cutting, longitudinally in two, the representation of the cap 3 of Figures: 6, 8, 11 and 17, and in addition the projecting tube 16 for Figures 8 , 17, 20, 21, 22 and 23., but which is highlighted in Figure 24, which does not require, and for good reason, suction pipes or additional elements. The appended drawings, given by way of nonlimiting examples, will allow a better understanding of the present invention.

It should be understood that the descriptions which precede or which will follow, are given only by way of examples and that they in no way limit the field of the invention, from which one would not depart by replacing the details of executions described, by any other equivalent.

The applicant specifies that the implementation techniques for the manufacture and layout of the molds are the same as those described in his French Patent of June 28, 1996 already cited (with the authorized improvements made to his PCT filing of June 30, 1997 , entered the national phase). Limiting itself, on this subject, to refer to this Patent, in order to devote itself within the framework of the present invention, to providing the technical explanations on the means used to make integral by overmolding in particular "the one-piece closure" with "straw aspiration "as well as those concerning the improvements made to the closure caps of any kind: spirol threaded or not, from its French patent of August 4, 1998,

Figure 3 shows in longitudinal section an injection mold of a "suction straw" for flat or milk drinks, obtained from the two injection holes 13, located on the line of confrontation of the upper face of the shells 5 and (5 'not shown). Said mold being removably attached to a female mold 7 which is secured or embedded in a circular plate 7 '. All of these two elements being able to move vertically by means of the jacks 7 ". For the formation of the tunnel 12, dug through the mass of the mold, here female 7, which extends into the injection mold, once its shells 5 and (5 'not shown) each hollowed out vertically on their facing face, are in facing position. The installation of a tube 12a, closed at its upper end, in the tunnel 12 dug in the mold female 7 and its extension between the shells 5 and (5 'not shown), takes place from an opening made in the plate 7'. The cannula 4b fixed inside the tube 12a is connected with a pipe 4a which is internal to a pipe 4 connected to the lower orifice of the tube 12a for the cooling circuit thereof. The tube 12a having a male role of injection, and the tunnel 12 a female role, with between them an annular injection space which makes it possible to obtain a tube 16 extended by a tube 16a. The techniques used are described by the applicant in the French Patent of June 28, 1996 and in the PCT filing already mentioned, in particular the cooling technique used.

According to the present invention, the female mold 7 is characterized to have, in the confrontation zone, a diameter R smaller than that of its lower and terminal part, by the arrangement of a flat (a). This arrangement, according to Figure 8, allows during the confrontation of the front face of this female mold 7 with the front face of the shell mold 5a and (5a 'not shown) to be able to penetrate inside the skirt 1 in contact with the inner wall thereof. Unlike the French Patent of August 4, 1998, the face of the mold, here female 7, is not dug with a vertical trench whose orifice is covered by the face of the shells 5 and 5 'of the secondary mold. According to the present invention, the facing face of the female mold 7 is hollowed out in its diameter, on each side of the tunnel 12, with a channel C not visible in this figure, with the exception of the bottom. This channel C is penetrated by the projecting part 5 ", not visible in this figure, of the face of confrontation of the shells 5 and (5 ′ not shown) and of a size making it possible to provide, between its walls, a space d "injection which defines two vertical membranes M", and which also gives the shells of this mold a female role, a male role of injection. The tunnel 12 has two slots (not shown) in the axis of each of the channels C to allow their injection, according to the technique described in the French Patent of August 4, 1998 already mentioned.

Figure 4 shows the elements of Figure 3 in restricted longitudinal section, along the line AA of Figure 3. We find the female mold 7 with its upper part having a reduced diameter R obtained by the flat (a). Its facing face hollowed out by a channel C. The injection mold with shells 5 and 5 'which have on their lower end face a projection 5 "which, at the time of the confrontation with the female mold 7, enters the channel C, while leaving an injection space between this 5 "projection and the side walls of channel C to obtain the injection of two membranes M '. In the background and in vertical and parallel dotted lines, the tunnel

12 on the outside, the hollow tube 12a on the inside with, between them, the wall of the tube 16 in the shell mold 5 and 5 ', and which extends into the female mold 7 through the tube 16a.

Figure 5 shows in cross section, along line BB of Figure 3, the shells 5 and 5 'of the mold, with its projecting part 5 "inside the channel C shown in oblique dotted lines from left to right, between the walls M 'which come from the injection of the tube 16, between the tunnel 12 and the hollow tube 12a with the cannula 4b of the cooling circuit.

Figure 6 is the longitudinal section of a "one-piece closure" for flat or milky drinks, and the shell 5a of the injection mold, as well as the section of the male mold 7a moving vertically by its cylinder 7a "to come into confrontation with the injection mold represented by the shell 5a, by arranging an injection space between them to form, according to the French patent of August 4, 1998, the skirt 1, extended by the covering part 2 and the cap 3 comprising a line circular of lesser thickness 19, with the projecting edges 3 'and its terminal part 4 which are injected from the injection point 13 arranged on the line of confrontation of the shells 5a and 5a' (not shown). invention the face of confrontation of the male mold 7a is hollowed out of two cavities 2a, the bottom C of which corresponds to the face of confrontation of a shape identical to the channel C but with narrower dimensions than the projecting parts 5 "of the shells 5 and 5 'rep shown in Figure 4. These cavities 2a which communicate with the partially covering part 2 are injected at the same time, but these cavities 2a do not reach the skirt 1 due to the presence of the male mold 7a in the circular area adjoining the skirt 1 which temporarily closes the hole obtained through the wall thereof according to the technical indications previously supplied by the applicant to form the horizontal injection point 13a. The withdrawal of the male mold 7a and its replacement by the female mold 7 provides the injection space 2a 'visible in Figure 10.

Figure 7 shows in restricted longitudinal section, along line CC of Figure 6, the shells 5a and 5a 'of the mold "A" and the mold male unit 7a with its cavity 2a at the bottom C delimited by the horizontal dotted lines of the face of confrontation of the shells 5a and 5a 'of the injection mold. This cavity 2a constitutes under this aforementioned cavity 2 also an appendage 2a. in vertical and parallel dotted lines, the limits of the cap 3 and its thinner line 19.

FIG. 8 shows in longitudinal section the "one-piece closure" for flat or milk drinks, and the shell 5a of the injection mold according to FIG. 6, "the suction straw", as well as the section of the corresponding female mold 7, alone, in Figure 3, having internal: the hollow tube 12a, the tubing 16a and the hollow tube 12a; released from the shells 5 and 5 ': the hollow tube 12a and the extension 16 of the tube 16a of the "suction straw" for still or milky drinks, positioned between the internal wall of the removable cap 3, which was possible by the reduced diameter R constituted by the flat (a) of the female mold 7, allowing it to be inserted in the shell mold 5a and (5a 'not shown); not visible in this Figure: the injected part 2a according to Figure 6, which is inserted between the parallel membranes M 'according to Figure 5, and the bottom of the channel C according to Figure 4, always keeping the two spaces free 'injection 2a', one of these two spaces opens onto the internal orifice projecting from the horizontal injection point 13a, after the withdrawal of the male mold 7a of Figure 6 replaced by the female mold (7). We recognize the skirt 1 with its hole formed around the projecting cannula of the horizontal injection point 13a, and the covering part 2 integral with the part 2a inserted between the membranes M ', only one of which is visible, resting on the bottom. of the channel C of the female mold (7) In contrast, the part 2 is extended by the cap 3 with its thinner line 19 and the two vertical projecting edges 3 ′, taking account of the warning on page 2 of the lines 9 to 12 and explanations provided on page 8, lines 10 to 18. The end part 4, of the cap 3, may not block the orifice of the "suction straw" 16, to facilitate removal by twisting the cap, leaving a space even minimal, which allows at the same time when placing it in the capacitor, entering the conditioned drink, to let the air in " the suction straw ", evacuate as it penetrates in the drink. After the installation of this set: "one-piece closing-suction straw", and during various manipulations, the quantity of drink escaping through this space will be extremely low and will only be able to return to the container with the drink by borrowing the annular space which should constitute the vent 17, without externally affecting it.

- Figure 9 is a longitudinal and transverse section restricted along the line DD of Figure 8. limited to the lower part of the shells 5a and 5a ', as well as to the upper part of the female mold 7, We find the female mold 7 with its reduced diameter R constituted by the flat (a) and its end face 7 which is in confrontation with the partially covering part 2 and its extension 2a, in the shell mold 5a and 5a 'according to Figure 7, and come to be lodged in the channel C between the parallel membranes M 'of Figure 4, obtained with the assistance of the projecting part 5 "of the shells 5 and 5' of this same Figure. The parallel membranes M ', with the channel C of which only distinguishes its bottom, are dependent on the female mold 7, which is inserted between the skirt 1 of the shells 5a and 5a ', leaving a circular injection space 2a ". In vertical and parallel dotted lines we find the removable cap 3, with its line of lesser thickness 19, surrounding without touching the tube 16, with between them an annular space 17.

11 - Processes for producing a horizontal injection point according to claims 2, characterized in that it is constituted by a rectilinear cannula of uniform diameter, preferably made of steel, which is longitudinally infinitely greater than each of the semi tunnels - cylindrical and identical, dug unilaterally and horizontally from the front edge of the shells (5a-5a ') of the molds "A" and "B" of the carousel "UN", so as to form, during their confrontations, a tunnel cylindrical having inside the aforementioned cannula which projects substantially from the internal face of each of the aforementioned shells (5a-5a '); for this purpose, the longitudinal half-diameter of the cannula is placed on the wall of one of the semi-cylindrical tunnels of one of the shells, for example the shell (5a) and they are made integral by welding, preferably at laser; during the confrontation of the shells (5a-5a ') of the aforementioned molds, which must be total and flawless, the other longitudinal half-diameter of the cannula is housed in the semi-cylindrical tunnel of the shell (5a' ) to match its contours and form the horizontal injection point (13a); for the case where the clashes of the mussels of the merry-go-rounds should clash perpendicular to the rotary movements, it is obvious that the tunnel would always and preferably be cylindrical, but dig only from the rear face of the shell (5a ) given for example, molds "A" and "B".
