FR2782067A1 - Closure for bottle with drinking straw to contain carbonated beverages has molded neck and coaxial tube forming immovable apron with cap to twist off at break line - Google Patents

Abstract

To produce the closure for a bottle holding carbonated liquids and with a drinking straw, a steel injection mold is used to mold a plastics cylinder tube with a projecting tube section (15) at its upper end. A second and coaxial projecting tube section (16) is locked to the outer tube (15) by a vertical membrane (M) in the vertical and hollow space of the bottle neck (15) between it and the inner extension (16a) of the second tube, but independent of its wall. After closure by the die action on the base, the material is blown into the mold. The second projecting tube (16) has a horizontal and circular projection as a thin blade (L) which can be raised at its outer periphery by the pressure of a carbonated liquid, such as a beverage. The membrane (M) is inserted into the bottle neck (15) at the inner tube (16) as far as the inner neck (15) limit for the lower inner tube projection (16a). The two-part mold has a hollow trench at the upper male section across its butting face, recessed in a circular honeycomb with notches. The facing female mold section forms the injection ring cavity for the bottle neck (15) and its flats (18'). The second mold section has three vertical blower passages, where two open over the neck (15) opening and preferably flanking the membrane (M), and the third opens over the hollow tube closed at the top to butt against the lower surface of the second mold section flanking the third passage. The trench at the male section has a center passage across it, in a longitudinal and cylindrical shape, which itself contains a coaxial hollow steel tube, preferably closed at the top to form an inner cooling channel. The hollow channel has two diametrically opposed openings as a direct link with the trench openings, shaped by two rows of vertical and parallel pins in the shape of the figure 1, for the injection of the membrane (M). A thin and circular opening matches a horizontal and semi-circular opening, hollowed at each of the butting surfaces of the shells, with a direct link between them for the injection of the circular blade (L). The female mold section also has the hollow zone for the injection molding of the coaxial inner tube (16) and also the passage which ends at the inner limit of the membrane (M) at the male mold section. An Independent claim is included for a monobloc closure with an apron which clings tightly round the bottle neck (15) to lie on the flat (18') as a limit, with a lock (1') at the flat (18'). It is extended (2) to give a partial non-sealing cover round the neck (15) with a shoulder (2') and a support (17') for the blade (L) in an immovable assembly. It is extended by a removable cap (3), with a weakened and thinner break point (19). The cap covers (4) the opening of the projecting tube (16). The cap (3) can be held to the immovable section by a thin and flexible bond, formed by extrusion molding. The cap (3) has two opposing projections, as a grip to twist off the cap. The projecting grips can be of metal or plastics, formed during molding, to twist off the cap and separate it from the immovable section along the line of least resistance. The break line can be a continuous ring of thinner material, or intermittent thin zones forming a weaker line in the material.

Description

-] - According to its French patent application filed on February 4, 1998 under the

  n 98.01275, concerning a one-piece closing device. This is characterized by an irremovable part which encloses the neck, but without its covering part completely blocking its orifice, which is extended by a removable cap surrounding without touching the projecting part or "straw" of suction, which leaves an annular space around it. This cap closes the orifice of the neck, by penetrating it superficially but sufficiently, which allows at the same time to close this bottle-torch. The skirt which extends the mentioned covering part, carries two light davits between which there is a notch where the upper flat part of the neck is inserted; this skirt is secured to the latter above the lower flat, by known thermal means. The cap is made removable by a circular line of reduced thickness with controlled weakness on which it suffices to exert a twist to separate it from the irremovable part and remove it. The annular space then turns into a vent, facilitating use

  suction "straw" to access the drink contained in this type of bottle

Blowtorch.

  But in the context of the present invention which makes dependent on each other, the internal and projecting tubing with a variant of the closure device which was the subject of the filing of February 4, 1998, the applicant will describe the combination below. allowing the internal and projecting tubing to be secured to the projecting tubing forming both the body of the cylindrical tube and its neck, the starting point for obtaining, by blowing

  indirect, in a suitable shell mold, this type of Blowtorch Bottle.

  In his French patent filed on June 28, 1996 under No. 96.08141, the applicant explains the process of manufacturing a bottle-torch obtained by injection-blowing, from the injection into a suitable mold, of a cylindrical tube

protruding and internal tubing.

  The three projecting tubes are arranged side by side and respectively:

  - The first for filling the Torch bottle.

  - The second as suction "straw" since extending internally.

  - The third as a vent (these last two each have a line

  circular of lesser thickness allowing on these lines, a separation by torsion).

  According to the explanations provided in the said patent, the blowing of this tube is carried out indirectly from a secondary injection mold. This arrangement alongside

  side of the protruding tubes, leads to their closure after filling the bottle-

  Blowtorch several operations which slow down the rate of production to its final point: - Sealing of the filling orifice, by the installation of a closure capsule. -2- 1 Closing by self-welding and pinching the orifices of the two remaining tubes. - Possible installation of hygienic protection of the tubing used

as suction "straw".

  it is the same to be able to use the bottle-torch: -Possibility of removing the hygienic protection protecting the suction "straw". - Removal by torsion of the self-welded part of the "straw" on its circular line of less thickness allowing its use to suck the drink

contained.

  -Perform a similar operation on the tubing serving as a vent.

  However, this one-piece closing device is not sufficient, in itself, to obstruct the moment of its opening by removing the cap, to a rise and overflow of a carbonated drink, after the exit of the C02 under pressure which comes

  accumulate above the level of said drink in the neck area.

  While waiting to describe the various provisions improving the manufacture and the use of a bottle-torch, the applicant is led to develop the brief

  description made in his French patent of February 4, 1998, concerning the news

  provisions of the projecting tubes of the cylindrical tube, compared to those of its French Patent of June 28, 1996 no 96.08141; but without having to intervene on the means used to obtain by injection an internal protruding protrusion, the techniques implemented and claimed in this patent are not concerned and do not even have to intervene within the framework of the present invention; this is the reason why, the applicant has not represented in its entirety the female 6 and male 7 elements of the main mold in the Figures where they are highlighted, but only the upper and terminal area of these which only are interested in the

present invention.

  But before going further in the explanations relating to the various improvements made by the applicant, some being dependent on the new characteristics brought to the closure device and some requiring, in certain cases, for its realization, the participation of the "straw" of suction and in all cases the participation of the neck and even in other cases the participation of the

  body of the cylindrical tube before it narrows to form the neck of the future bottle-

  Blowtorch, but then also with the use of a double bar mandrel. All these cases will be developed further, with the corresponding explanatory Figures in support of the present invention. These new closure devices are essentially remarkable for the multiple advantages they provide, before and during the use of the capacitors of this type of bottle-torch which are linked to it and vice versa, and first of all: - One-piece tamper-evident closure, as soon as it is installed, with a part

  irremovable extended by a removable cap.

  - Protection of the "straw" against any pollution. - Separation of the removable cap by simple twisting on its line

  circular of reduced thickness with controlled weakness.

  - Creation of an annular space serving as a vent, replacing the tubing 17 of the

  French patent of June 28, 1996 n 96.08141.

  - Easy removal and replacement of the removable cap by installing a thin and flexible link connecting this cap to the irremovable part by using the material of

creep from the matrixing.

  This last provision can only materialize insofar as this closure device is obtained according to the extrusion-molding technique described in its French patent of August 9, 1961 No. 1.344.169 and its Additions, but cannot be obtained according to injection-molding technique. The cap can preferably be striated and include, if necessary, taking into account its reduced size, a slight vertical projection improving its grip and the effort necessary for its opening. This technique is also claimed by the applicant in the context of this

  invention, for all kinds of plastic closure caps or the like.

  Before referring to Figures which have been the subject of separate Patents, and in order to make it possible to understand, without possible confusion, the technical improvements made by the applicant, the numbering of the references and corresponding Figures of said patents will be put (in parenthesis ) with the n of this Figure and

  the date of the relevant French patent.

  While the connection between the external wall of the pipe 16 takes place with the external walls of the pipes 15 and 17, as well as with the wall 14 (Figure 3 / 28.06.96), the applicant is now passing the "straw" suction through the neck to project above its orifice (Figure 1 and 2 / 4.02.98), no longer on a horizontal plane, but on a vertical plane with the internal wall of the neck only, and on a Thin thickness does not interfere with the filling by this neck which has a diameter to conventional standards. The injected cylindrical tube completely envelops the suction straw, in its internal part, to shrink in order to form the neck, according to one of the different techniques developed further by the applicant, without or with the help of a mandrel. with double bars 22 and 22 '(Figure 11/28. 06.96), but not comprising

  a single hollow injection tube in its role as a male element.

  These new provisions included in the present invention necessarily entail, as specified from the start by the applicant, a one-piece fitting device comprising a non-removable part extended by a removable cap; however, several variants of this device, depending on the destination of use, are provided, some in combination with the suction straw which will be developed further; as for the tubing used as a vent (Figures 3, 3a, 6 and 8 / 28.06.96) it is eliminated in the context of the present invention, its role of vent being held by a device of the integral closure, intimately linked the new provisions of the remaining protruding tubes which are interdependent on each other, which cannot be conceived of without the others being taken,

in isolation, useless.

  It should be understood that the descriptions which precede or which will follow, are not

  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. On the other hand, the applicant will limit themselves solely to giving the technical explanations of the manufacturing process on the new arrangements of the protruding and internal pipes concerned by the present invention; for the references not concerned, the applicant refers to the patents mentioned as well as the Figures -6- 1 concerned put in brackets with the presentation of the Figures, he will join the said

Figures for comparison.

  According to FIG. 1, the male element 7 of the main mold allows the injection of a cylindrical tube 14 which narrows in its terminal part to form the protruding tube which we will denote "neck". This cylindrical tube 14 is characterized in that it comprises, internally, a second tube which, internally becomes protruding and is formed by injection between a tunnel 12 and a hollow tube 12a and shown in hatched form. The junction between the internal wall of the "neck" 15 is characterized by a vertical connection and over a very small thickness forming a membrane M which will be explained with Figures 2 and 3. The secondary mold represented by its shell 5 is characterized to include in behind its face of confrontation one or two blowing tunnels S which open above the "neck" 15 and behind the membrane M, while another blowing tunnel S is formed, during the confrontation of the shells of the secondary mold, by two half-tunnels. This tunnel opens above the closed part of the hollow tube

12a.

  FIG. 2 is a cross section along the section line in FIG. 1 and on the shells 5 and 5 'facing the secondary mold. We distinguish, starting from the center, the cannula 4b (see French patent, ais of 28.06.96 n 96.08141), the hollow tube 12a, the tunnel 12. Starting from the tunnel 12, the thin membrane M which joins from the inside the " "15

and the upper flat 18.

  FIG. 3 is a vertical section along the section line C C of FIG. 2 on the shells 5 and 5 '. The end part 7 of the male element is provided with a trench 7 'which passes entirely through it. During the confrontation of the upper end part of the male element 7 with the lower face of each of the shells 5 and 5 ′ in confrontation the material is injected by the arranged tunnel 12, allowing this lateral and vertical injection (while in its French Patent of June 28, 1996 n 96.0141 this injection is carried out horizontally and from the formation of the internal and projecting tubing with the external face of the tubing 15 also forming the "neck"; as well as with the cylindrical body and a third projecting tube serving as a vent). This arrangement of the trench 7 'allows the withdrawal of the male element 7, while ensuring a connection from the inside of the "neck" 15. There is also a distinction between the blowing tunnel S and the flats

18 and 18 '.

  FIGS. 4 and 5 are, in plan view, the shells 5 and 5 'facing the secondary mold which show that it is possible to arrange the blow tunnels in different ways. This provision is given only as an example. One distinguishes on each of the Figures, and in dotted lines, the contours of the "neck" 15, and of the tunnel 12 on one side and of the hollow tube 22a on the other, as well as the membrane M connecting from the inside the -7 - 1 "neck" 15. These Figures are only used to locate the elements shown in FIG. 1, 2 and 3. FIG. 6 represents a longitudinal section of the cylindrical tube 14 released from injection into the molds of FIG. 1 either: the body of the tube 14, its narrowed part forming the "neck" 15, with the membrane M coming by injection into the projecting tubing 16 extending internally 16a and which we will designate as suction "straw", it is located (integral with it) inside the "neck" 15, which has the flats

circulars 18 and 18 '.

  FIG. 7 is a section along the section line D D of FIG. 6 o we find, starting from the center, the unreferenced orifice of the suction "straw" 16 connected

  vertically by a thin membrane M and the wall 14 of the cylindrical tube.

  The applicant anticipated by mentioning the suction "straw", which will be effective at

FIG. 8.

  FIG. 8 shows with a partial cutaway, the bottle-torch obtained by indirect blowing in a shell transformer mold, not shown since not concerned by the present invention, but visible (FIG. 7 of its French patent of June 28, 1996 n 96.0141). As for this last, the hatched part in diagonals from left to right came from injection into the secondary mold of FIG.1 using the characteristics according to FIG. 2 and 3. We find the body of the Bottle 14a, its stamped bottom 14b, and its waste 14c, the neck 15 with its flats 18 and 18 ', its "straw"

  suction 16 extending internally 16a.

  FIG. 9 is a longitudinal section of the large-scale closure device, and relates to FIG. 1 of the French patent filed on February 4, 1998 n 98.01275 by the applicant and which describes therein the technical processes for its manufacture which are repeated to highlight the improvements made by the applicant in the present invention. As already mentioned above, this one-piece closure device is characterized by a non-removable part, extended by a removable cap, which can also be obtained by injection-molding but without a thin and flexible link connecting the non-removable part to its removable cap. , and with him using the

  extrusion-molding technique according to the French Patent of August 9, 1961 already mentioned.

  This device consists of a skirt 1, comprising a davit 1 '. This skirt 1 is extended by a covering part 2 which is characterized so as not to completely close the orifice of the neck of a bottle-torch according to FIG. 8, but itself

  continues with a cap 3 enclosing the "straw" 16 without touching it, leaving between

  them an annular space 17, and closing the orifice of the "straw" 16 by its terminal part 4.

  This cap 3 comprises a circular line of lesser thickness 19 according to the technique already mentioned by the applicant. The thin and flexible link 20 connects the cap 3 to the

  above its thinner line 19, at the covering part 2.

  FIG. 10 is a plan view, along the cross section of FIG. 9, this section being taken along the line E E of FIG. 9, we find the covering part 2, the cap 3, the "straw" 16 with, between the inner face of the cap 3, the annular space 17 which serves as a vent, when the cap is removed (and which replaces the protruding tubing with the same reference 17 of French patent n 96. 01410 of June 28

1996).

  L FIG. 11 is a longitudinal section of the bottle according to FIG. 8, with the closing device according to FIG. 9. We find the irremovable part 1 resting on the lower flat 18 'of the neck 15, its covering part 2, which is extended by the cap 3 with its part 4 which closes the upper orifice of the protruding tube 16, this cap 3 is made removable on its circular line 19 of reduced thickness with controlled weakness; it is connected to the covering part 2 integral with the irremovable part 1, by a thin and flexible link obtained by stamping using the creep waste according to the

  technique described in its French Patent No. 1,344,169 of August 9, 1961 and its Additions.

  The protruding tubing 16 passes through the inside of the neck 15 to extend internally 16a into the body of the bottle 14a and constitute the suction "straw". The membrane M, visible in FIGS; 1, 3 and 6, and in section in FIG. 2 and 7, is not indicated on this

  FIG. 11, to allow better clarity in the drawing.

  FIG. 12 shows the same elements and references as those of FIG. 1, but has an additional characteristic, with the formation by injection, of a circular lamella L, of very small thickness, but with a diameter sufficient to allow its terminal circular zone to rise under the pressure exerted by a carbonated drink by example. This strip L is obtained by practicing on each of the shells 5 and 5 '(not shown) of the secondary mold, an opening in an arc of a circle so that the plastic material injected from the opening made in the tunnel 12 can thus form this circular lamella L according to the technique described in French Patent No. 96.08141 of June 28, 1996 (FIG. 3). The usefulness of this L strip will be demonstrated

  thanks to the description and explanations relating to FIG. 15.

  FIG. 13 is a magnification along the longitudinal section of FIG. 12, but limited to the shell 5 of the secondary mold and to the upper end part of the male element 7 of the main mold which enters it. We find, more visible, the elements and

references of FIG. 12.

  FIG. 14 is a vertical section of the shells 5 and 5 'facing each other, along the double section line F F of FIG. 13. We find the shell 5 and its opposite 5 ', -9- 1 one of the blowing tunnels S, behind the facing faces of the shells 5 and 5', the circular strip L which is located on either side of the shells 5 and 5 'facing each other, the terminal element 7 provided with a vertical trench 7' which come into confrontation with the lower and end face of the shells 5 and 5 ', the neck 15 with its flats 18 and 18 '; the vertical trench 7 'allowing the creation of the membrane M which secures the tube 16 to the internal face of the' neck '15, which is visible in FIG. 1, 2, 6, 7, 12 and 13. FIG. 15 is a longitudinal section of another closure device with improvements made to that described in French patent no. 98.01275 filed on February 4, 1998. These improvements relate on the one hand to the improvement of the grip of the removable cap 3 by the constitution protruding edges 3 ′ and relates only to the closure device, on the other hand they include arrangements of the covering part 2 to constitute by 2 ′ a housing 17 ″ for the lamella L secured to the tube 16. As regards the projecting edge 3 ', it seemed necessary to the applicant to improve the grip of the cap 3 by fitting the shells of the extrusion-molding mold according to the technique claimed in its French patent n 1.344.169 of August 9, 1961 to allow be to use part of the fluent material by stamping at the time of the confrontation of the shells; they can also be obtained by the injection-molding technique and in a manner analogous to obtaining the flats 18 and 18 'of FIG. I for example. According to one or other of the techniques used, these edges which complement the vertical striations on the cap 3, are claimed by the applicant in the context of the present invention for any type of closure device causing a torsional movement. , whether the latter is made of plastic or any other metallic device, comprising a continuous or intermittent line of lesser thickness or point of weak resistance, which follows from the French patent of 1961, already

city of the applicant.

  Concerning the arrangement constituted under the covering part 2 ′, this constitutes a housing, at the time of the installation of the one-piece closing device shown, for the strip L coming in horizontal projection of the tube 16 of the bottle-torch 14a , unlike the membrane M which is a vertical outgrowth. It is common for any type of capacitor containing a carbonated drink, to find that when it opens, and following the escaping C02, to see that part of this drink follows the same path. The presence of the lamella L according to the present invention and its housing under the covering part 2 "constitute, together, an obstacle to this drawback. Indeed the carbonated drink contained in this type of bottle-torch according to the present invention, to follow the path of C02, will exert pressure on the thin lamella L; this and by its external periphery, will come to be pressed against the upper internal face of the covering part 2 ', leaving only a tiny amount at the start quantity of drink escaping at the moment when the cap 3, removable on the circular line of lesser thickness 19, will be removed by twisting As for the C02 which has come to accumulate above the surface of the drink located in the "straw" d suction 16, its quantity will be minimal, most of it being located in the region of the neck 15, no gas taking the reverse path of the liquid, to come back up in a central and internal conduit which represents the internal part 16a of this " pail the "suction, the

  the amount of drink that can escape there being negligible.

  According to FIG. 15 and 17 identical, but with different cutting lines, there are the constituent elements of the one-piece closure device according to the present invention, and the upper part of the tube 16 of the bottle-torch which will be interdependent, which cannot be conceived of. one without the other. The skirt 1 rests on the flat 18 'of the neck 15 which is vertically connected by a membrane M to the projecting tube 16 which extends internally 16a. The davit 1 'makes it possible to enter in force around the flat 18 (see at least FIG. 14), it will nevertheless be possible to ensure the irremovability of the skirt 1 around the neck 15 by a known thermal process. The covering part 2 is extended by 2 'to allow a space 17' for the circular strip L, coming from the projecting tube 16 at the time of its injection. The removable cap 3 on its thinner line 19, the protruding parts 3 'coming from stamping at the time of the confrontation of the shells of the mold used according to the technique of the French Patent of 1961 already cited, or according to an arrangement of each of the shells an injection mold having a female role, but only limited to the joint plane thereof, and not as for the formation of circular flats. The covering part 4 does not penetrate into the orifice of the projecting tube 16, which had the effect of braking and making it difficult to twist to separate the cap 3 on its thin line 19. The thin and flexible link 20 connects the covering part 2 to the cap 3, but above the thinner line 19; it is optional. Between the wall of the cap 3 and that of the tube 16, there is an annular space 17 serving as a vent, after separation of the

  cap 3, of the irremovable part 1, 2 and 2 '.

  FIGS. 16 and 18 are plan views along the cross sections G G of FIG. 15 and H H of FIG. 17, where we find on each of them the elements

  referenced to the Figures mentioned according to the longitudinal section of each of them.

  FIG. 19 shows another arrangement in longitudinal section of a shell of the secondary mold, female 6 and male 7 elements of the main mold, with a double bar mandrel 22 and 22 'comprising only a hollow injection tube 22a, this which characterizes the formation of the membrane M, no longer flush with the orifice in its terminal part, but from the terminal part of the neck 15, it being understood that this membrane M can be located at any level of the neck 15, but impossible at a level lower than that shown in this FIG. 19, to allow the withdrawal of the hollow injection tube 22a from the double bar mandrel 22 and 22 '. The cooling is carried out as for the device illustrated and explained (in its French patent n 96.08141 of June 28, 1996), according to the arrow direction. Found from the bottom up, the upper part of the female 6 and male 7 elements (compare with FIG. 3 of French patent n 96.08141 of June 28, 1996), communicating cavities 8 and 8 ', the partition 9 of the tunnel 12 hatched, the internal tube 16a between the wall of the hollow tube 12a and the tunnel 12, inside the hollow tube 12a the cannula 4b serving for the return of the coolant coming from the hollow tube 12a, in the direction of the arrows ( and forming part of French patent n 96.08141 of June 28, 1996). The membrane M vertically joining part of the tubing 16a with the body of the cylindrical tube 14; coming into confrontation on the terminal part of the male element 7, the hollow tube 22a which limits in its terminal part the membrane M, and constitutes a male element for the injection of the narrowed part 15 (future neck 15) and its flats 18 'and 18. It should be noted that in this securing arrangement of the suction "straw" formed by the pipes 16 and 16a, it is not possible to obtain the strip L as in the provisions of FIG. 12,13, 14, 15 and 16, which excludes with this provision, to prevent an untimely rise of a carbonated drink. After removal of the double bar mandrel 22 and 22 'and of the hollow tube 22a which at the same time encloses the hollow tube 12a while leaving an injection space to form the protruding tube 16, the indirect blowing mandrel will come into confrontation with the upper end face of shells 5 and 5 '(not shown) of the secondary mold, occupying the vacuum left by the withdrawal of the tube

hollow 22a (not shown).

  FIG. 20 is a longitudinal section of the cylindrical tube injected into the molds used in FIG. 19. The applicant recalls that for the lower parts of all the partially represented molds, these do not differ from those represented in his French patent n 96.08141 of June 28, 1996 where the technique can be consulted, while specifying that certain improvements have were made when the PCT / FR97 / 01162 application of June 30, 1997 (filing of

  international publication: WO / 98/00280) of January 8, 1998.

  In this FIG. 20, a distinction is made, coming from injection between the female 6 and male 7 elements of the main mold, the cylindrical body 14, as well as its narrowed part, before the neck 15. The internal tube 16a has come from injection between the wall of the tunnel 12 limited by the partition 9 and the hollow tube 12a, the latter playing a role of male element, while the tunnel 12, forming part of the male element 7, has a role of female element. Came from injection into the secondary mold with shells 5 and 5 '(not shown) the part -12- 1 narrowed, forming the neck 15 with its flats 18 and 18', as well as the extension of the internal tube 16a, c 'is to say the projecting tube 16. The membrane M which comes from the external wall of the tube 16a before its extension into tube 16, joins from the inside the wall of the neck 15. This membrane M, as in all those shown, is vertical and occupies only a limited space inside the neck 15 which cannot affect the filling of the future bottle-torch, the filling tube comprising, in certain cases, a vertical slot to allow its descent to the inside the neck 15. Naturally, this said filling tube will include the conventional provisions for the evacuation of the air expelled by the rise of the drink, or else a device designed by the applicant in the 1st Addition n 88.254 of April 17, 1963 French patent

n 1,386,210 of January 15, 1963.
