Description

Bottle and its manufacturing process

The invention relates to the field of bottles and their manufacturing processes.

The term "flask" is used herein to denote a rigid object intended to contain a fluid content (liquid, viscous or pasty) to be dispensed. Such a bottle may have a closed sealed configuration, in which the fluid content can freely exit the bottle. Such a bottle may also be placed in dispensing configuration, in which the contents are dispensed out of the bottle. Such bottles are used in particular in the field of cosmetics or spirits.

In the field of packaging, there are other types of container than the bottles. Illustratively, the boxes described in US 2010 / 065,557 can be referred to as an example of other types of containers. There are rigid plastic bottles allowing great freedom in the form or manufacturing process. For example FR 2 813 291 describes a bottle to which a "traveler" bottle can temporarily be connected for filling the "traveler" bottle from the main bottle. Another example of a plastic product is, for example, US 6, 135,523. However, plastic bottles are not appropriate for certain market segments, in which bottles with a glass container have traditionally been used. However, glass is a material difficult to implement from an industrial point of view, because of its demanding manufacturing process (high temperatures in particular), which can result in a wide dispersion of manufactured products due to manufacturing tolerances. This great dispersion poses particular problems when it comes to achieving a reliable and durable seal of the bottle in its closed configuration. To reduce these problems, it is traditionally implemented a blowing process that defines a large glass container, with a narrow neck on which is implemented the sealing function. As the glass neck is narrow, it is possible to oversize the sealing solution to ensure that a sealed vial is provided despite the dispersion of the manufacturing process.

Recently, attempts have been made to overcome the traditional form of glass vials having a narrow neck. A so-called "in direct press" process has been described in EP 2 602 232. This process may, if necessary, be completed by a blowing step, but the basic geometry of the glass container may, however, have an opening. large compared to traditional passes. On such large openings, sealing issues become complex. This direct press process also makes it possible to provide different profiles for the cross section of the opening, and in particular non-circular profiles. For such profiles, because of peripheral non-uniformity, sealing issues are also complex.

FR 2 840 888 gives the example of a container comprising either a cylindrical unitary body or two cylindrical bodies connected together by a reinforcing disk. The constituent material mainly described for cylindrical bodies is polypropylene, although a long list of possible materials is given. The contents are held in flexible pockets assembled to the dispensing system. It is intended to allow the outside air to enter the space between the flexible bag and the outer wall. At the level of the distribution system, it is envisaged valves allowing closure of the air circuit when the pump is not actuated. For the embodiment involving a reinforcing disk, the implementation of such valves at the level of the connection between the reinforcing disk and the cylindrical body is however neither envisaged nor conceivable. In addition, we are still looking to diversify the bottle offering and to enrich the existing bottles with new features, to allow the development of innovative products. Hereinafter, a presentation of the invention.

The figures of the drawings are now briefly described. Figure 1 is a front view of a bottle according to one embodiment of the invention.

FIG. 2 is a schematic exploded perspective view of a portion of the bottle of FIG. 1. FIG. 3 is a sectional view of the detail indicated in FIG. 1.

Figures 4, 4a and 4b are schematic views of methods of manufacturing glass container bodies that can be implemented in the context of the invention.

Figures 5, 6, 7 and 8 are views similar to Figure 1 for other embodiments.

Fig. 5a is an illustrative detail view of the embodiment of Fig. 5.

Figure 9 is a view similar to Figure 2 for a portion of the embodiment of Figure 8. Hereinafter a detailed description of several embodiments of the invention with examples and reference drawings. Figure 1 shows schematically a bottle 1. The bottle 1 comprises a closed container 2. The closed container 2 defines an interior volume capable of containing a content 3. The content 3 is fluid, for example liquid or pasty, and may for example be a cosmetic product, for example a perfume, a food product, a spirits, or other . In particular, the content 3 may be more volatile than water. The bottle 1 also comprises a dispensing system 4. The dispensing system 4 is assembled to the container 2 and is adapted to dispense the contents 3 out of the closed container 2. It may be stated that, in the example presented, the container 2 is permanently closed during normal use of the bottle 1 by a user, and that the dispensing system 4 is the only way to distribute the contents 3 out of the container 2.

According to the first embodiment shown in FIG. 1, the container 2 consists of at least three distinct parts. The container 2 comprises a first sub-bottle 105, a second sub-bottle 106, and a closure system 7. The first sub-bottle 105 is constituted by a first glass container body 5. The second sub-bottle 106 is constituted by a second glass container body 6. The closure system 7 is disposed between the first and second glass container bodies 5, 6. The closure system 7 is connected to each of the first and second glass container bodies 5, 6. When we speak of "distinct" parts, we refer to the fact that these parts are constituted by separable objects from one another in space, even if there is no provision for such separation during normal use. of the bottle by a user, and even if such a separation could be impossible or difficult, once the bottle assembled.

The first glass container body 5 is described hereinafter. The first glass container body 5 is mainly made of glass. Any type of glass compatible with the intended application can be used, and in particular glasses already used today in the bottle industry. As can be seen in particular in FIG. 2, the first glass container body 5 comprises a bowl portion 8 and a mouthpiece 9. The bowl portion 8 and the mouthpiece 9 are integral. The bowl portion 8 defines the major part of the first glass container body 5. It has a shape suitable for containing content 3. The mouth 9 extends the bowl portion 8, and has a functionally defined shape for an assembly of the first glass container body 5 with another component. In particular, the mouth 9 is adapted for assembly with the closure system 7. In particular, the mouth 9 has a particular relief 10 adapted to cooperate in complementary form with a complementary relief of the closure system. In the illustrative embodiment shown, the relief 10 comprises a continuous peripheral radial bead 11, and a continuous peripheral ridge 12 juxtaposed to the bead 11 and disposed after it in a so-called assembly direction.

It may be noted that the mouth 9 may be described as large opening. In the field of the flask, an opening is said to be large when the order of magnitude of the dimensions of the opening is of the order of those of the bowl portion 8. In particular, the glass container bodies with large aperture are distinguished from the flasks traditionally made by blowing which have a narrow neck compared to the general dimensions of the glass body. A glass body of large aperture can in particular be made by a pressing method, as will be described later with reference to Figures 4, 4a and 4b. It should be noted that the present definition does not exclude that a blowing step is carried out during manufacture of the glass container body, as long as the definition of a large opening given above remains satisfied.

When referring to the shape of the section of the mouth 9, reference is made in particular to the sectional shape of the radially inner surface of the first container body 5 at the mouth 9, knowing that the external shape at the level of the mouth 13 is dictated functionally by that of the radially inner surface, and if necessary functional sealing assembly. As regards the shape of the section of the radially inner surface of the first container body 5 at the mouth 13, any suitable shape, such as a circular or non-circular shape. We can provide a polygonal shape with rounded edges, oval, ellipsoid, and in particular any non-circular craftable shape. In the case of a non-circular shape, the person skilled in the art knows what level of regularity is expected in the case of a surface formed during a glass pressing process. A non-circular shape is considered as such from the moment when a person skilled in the art knows how to determine, by observing the shape, that it was intentionally fabricated to be non-circular. Thus, by non-circular, it does not cover circular shapes for which defects in shape due to the manufacturing process change the shape with respect to an ideally desired geometric circle. By way of example, a non-circular shape will be considered as such if there is a difference greater than 2% between the nominal diameter of a surface considered and the diameters inscribed and circumscribed to this considered surface. A difference of more than 20% is quite possible. The shape in question is that of the inner surface, and / or the outer surface, independently of the projecting hooking reliefs, such as the bead 28. The first glass container body 5 is also provided with a dispensing opening 49. The dispensing opening 49 is provided on the opposite side to the mouthpiece 9. The dispensing opening 49 may for example be described as a small opening, with reference to the mouthpiece 9. The dispensing opening 49 may be performed in a neck 50 typical of glass vials. An example of a closure system 7 is given in relation with FIG. 2. In this purely illustrative example, the closure system 7 is complementary to the mouth 9 of the first glass container body. The closure system 7 comprises a sealing system 13 and a separate locking system 14.

The sealing system 13 comprises a body 15 and a clipping portion 16 integral with the body 15. The sealing system 13 comprises, in the embodiment shown, two integral portions, a first portion 17 cooperating with the first container body 5, and a second portion 18 cooperating with the second glass container body 6. For the moment, only the first portion 17 will be described. The first portion 17 comprises a body 19 and a clipping portion 20. The clipping portion 20 is secured to the body 19. The clipping portion 20 has a shape substantially complementary to the first glass container body 5 at the mouth 9 In particular, the clipping portion 20 comprises, in cross-section, a U-shape with a base 21 of which two parallel wings 22 and 23 extend. The so-called internal flange 22 is intended to be arranged opposite an inner face 24 of the first glass container body 5, and the so-called outer wing 23, is intended to be disposed facing an outer face 25 of the first glass container body 5. The outer face 25 of the first body The glass container 5 is opposed to the inner face 24. Thus, the clipping portion 20 caps the first glass container body 5 at the mouth 9.

The outer flange 23 is connected to the base 21 in an elastically deformable manner with respect thereto. The outer flange 23 carries an assembly relief 26 complementary to the relief 10 of the mouthpiece 9. In particular, the inner face 27 of the outer flange 23, carries a bead 28 projecting radially inwardly. In the assembled state of the first glass container body 5 with the sealing system 13, as shown in FIG. 3, the bead 28 is received in the rib 12. In this state, the bead 28 cooperates with the bead 11 to hold together the sealing system 13 and the first glass container body 5.

The sealing system 13 cooperates with the first glass container body 5 to define a tight connection between these two elements. Thus, the sealing system 13 and the first glass container body 5 are in intimate contact to prevent the contents 3 from flowing between them. The contents 3 are directly in contact with the glass container body 5 and the sealing system 13. In the purely illustrative example shown, the sealing system comprises a support piece 29 and a seal 30 carried by this support piece. The seal 30 is assembled in any appropriate manner to the support piece 29, in particular by overmolding. In the purely illustrative example shown, the seal 30 cooperates closely with the glass container body 5. In particular, the seal 30 may comprise an L-shaped cross section, a first branch 31 of the cooperating L the inner face 24 of the first glass container body 5, and a second L-branch 32 cooperating with the wafer surface 33 of the first glass container body 5. The wafer surface 33 of the first glass container body connects the inner face 24 and the outer face 25.

Various shapes and configurations of the seal may be provided. For example, the two portions of the L are not completely contiguous on the periphery of the joint, if at all. Apart from the L-shape previously described, it is possible for example to provide a U-shape, comprising the L-shape previously described, and an additional branch extending from the branch 32, parallel to the branch 31, and applied between outer flange 23 and the outer face 25 of the glass container body 5. Where appropriate, it is possible alternatively to provide an L shape, defined starting from the U-shape just described, but without the branch 31. In this last exemplary embodiment, it would be possible to dispense the sealing system 13 from the flange 22. The seal 30 may alternatively have a section of substantially triangular shape so that one face of said seal comes to compress against an edge of the glass container body 5 formed between the wafer surface 33 and the inner face 24.

According to one embodiment of the invention, the seal 30 comprises at least one protruding element or sealing lip capable of forming a sealing line against the surface of the container body 5. Preferably, the at least one lip The seal is of tapered shape or has an outer surface of a partially circular cross-section.

In the example, the seal 30 comprises two sealing lips (as shown) each capable of forming a sealing line against the inner face 24 of the container body 5.

A number of sealing lips greater than two may also be envisaged, especially when the seal 30 is configured so as to form a tight connection between the sealing system 13 and only one of the surfaces 24, 25 or 33 of the container body 5 .

When at least two sealing lips are used, they may also, depending on the configuration of the gasket 30, be arranged so as to each form a sealing line against several of the surfaces 24, 25, 33 of the container body 5.

According to a variant, the body 19 and the seal 30 are monobloc and formed of the same material. This applies in particular in the case of polyethylene material, or high density polyethylene. The characteristics of the gasket 30 as well as the embodiments detailed above can be adapted to the single body 19.

In practice, the geometry shown in FIG. 3 is identical or similar throughout the periphery of the first glass container body 5.

The assembly of the first glass container body 5 with the sealing system 13 defines a first closed receptacle 34 whose interior space is accessible only via the dispensing system 4.

Components likely to be in contact with the contents (in particular the support part 20 and the seal 30) are chosen to meet compatibility requirements (the product likely to be contained in the bottle does not deteriorate the component ) and neutrality (the component does not release compound into the product liquid in undesirable proportions). These requirements include the constituent materials of these components, or their manufacturing process. These requirements may depend on the content. The relationship between the sealing system 13 and the second glass container body 6 is now described.

In general, the description above of the relationship between the sealing system 13 and the first glass container body 5 applies to the relationship between the sealing system 13 and the second glass container body 6.

For example, for simplicity, a particular case is first described where the second glass container body 6 is symmetrical with the first glass container body 5 with respect to a Y-Z symmetry plane. The plane of symmetry Y-Z is orthogonal to the assembly direction. In such a case, the second portion 18 of the sealing system 13 is symmetrical with the first portion 17 of the sealing system 13 with respect to the plane of symmetry Y-Z. In addition, the first and second portions 17, 18 are of material at the plane of symmetry YZ, that is to say, in the example presented, forming a continuous central core 62 with the base 21 of the portions of FIG. clipping 20 of each floor.

Thus, where appropriate, a feature of the second glass container body 6 is designated by the same reference sign as the corresponding feature of the first glass container body 5, with the addition of a sign. For example, reference 9 'denotes the mouth of the second glass container body 6. This also applies to the closure system 7.

Thus, the bodies 19 and 19 'of the first and second portions 17 and 18 together form the body 15 of the sealing system. The clipping portions 20 and 20 'of the first and second portions 17 and 18 together form the clipping portion 16 of the sealing system.

The assembly of the second glass container body 6 with the sealing system 13 defines a second closed receptacle 35 whose interior space is accessible only via the dispensing system 4.

The closure system 7 also comprises a locking system 36. The locking system 36 encloses the sealing system 13 on each of the first and second glass containers 5, 6. In a purely illustrative example given, the locking system 36 comprises a rigid peripheral band 37 surrounding the sealing system 13 and held taut with a certain tension. The band 37 is for example a thin metal strip. More particularly, the band 37 comprises an inner face 38 and an opposite outer face 39. The inner face 38 is turned towards the inside of the bottle. The inner face 38 bears on the outer face 40 of the sealing system 13. In particular, the inner face 38 bears on the outer face 40 of the outer flange 23. The inner face 38 of the band 37 prevents deflection of the outer flange 23 out of its assembled configuration shown in Figure 3. In particular, the inner face 38 of the band 37 prevents an outward deflection of the outer flange 23 which would allow the reliefs 10 and 26 of assembly to disengage from each other.

In the embodiment shown, symmetrical with respect to the YZ plane, the description given above applies as well to the wing 23 of the first portion 17 as to that of the second portion 18. The strip 37 has come of material at the plane of symmetry YZ. In one example, the strip 37 is housed in a housing 41 defined inside the overall geometrical envelope of the first and second glass container bodies 5, 6. The wafer 43 of the strip 37, interconnecting the inner faces 38 and external 39 thereof, is in contact with a shoulder 44 of the first / second glass container body 5, 6. This configuration makes it possible to limit the deposit of dust or parasitic bodies. It can be provided that the outer face 39 is flush with the outer face 42 of the first and second bodies of glass containers 5, 6. This arrangement prevents free access to the protruding edges of the bottle.

The embodiment presented above is said to be symmetrical with respect to the Y-Z plane. Note that alternatively, one could resort to an embodiment that is not symmetrical with respect to the Y-Z plane. An example of such an embodiment comprises a second glass container body 6 of which only the mouth is symmetrical, with respect to the Y-Z plane, of the mouth 9 of the first glass container body. In this case, it will be possible to use the same closure system as that described above. The bowl portion of the second glass container body 6 may be of any shape so long as it can be made and integral with the mouth of the second glass container body. When referring to any shape of the vessel portion, reference may be made to both the inner and outer shape thereof. Thus, it will be possible to make bottles of very varied shapes by implementing the present invention.

Alternatively, the mouths of the first and second glass container bodies 5, 6, and the closure system 7 is not necessarily symmetrical with respect to the Y-Z plane, as long as a tight closure of the two receptacles is achieved. In particular, the first and second glass container bodies may have asymmetrical shapes.

The dispensing system 4 comprises a dispensing member 51. The dispensing member 51 may for example be a pump. The dispensing member 51 is assembled on the glass container body 5 by any suitable means. For example, the dispensing member 51 is crimped onto the neck 50. In a variant, it is possible, for example, to use snapping or screwing. The dispensing system 4 may comprise a plunger tube assembled to the dispenser member 51 and allowing access to the product contained inside the receptacle 2.

According to a schematic embodiment, the dispensing member 51 comprises a first product outlet 52, a first duct 53 adapted to guide the product likely to be contained in the first receptacle 34 to the first product outlet 52, and a first user operable actuator 54 for controlling an output of this product through the first product outlet 52.

The first actuating member 54 comprises a base 55 attached to the glass container body, and a movable member 56 relative to the base 55, and including an actuating region 57 accessible to a user, and operable to control the output of the first product, the movable member 56 carrying the first product outlet 52.

The bottle that has just been described can be made as follows:

As shown in FIG. 4, as shown very schematically, a body cavity 45, a large opening cavity 46 and a punch 47 forming a cavity receiving a glass parison 48 are used. The punch 47 is movable relative to the cavities 45 and 46 between an output position, and an input position in which the cavity gives the future shape of the first glass container body 5. As understood, the first glass container body 5 therefore has a wide opening to let the punch 47. The punch 47 defines the internal shape of the first glass container body 5, and the imprints its external shape. The large aperture imprint 46 may be used to shape the mouth of the first glass container body 5. The bottom 58 of the body cavity 45 may be used to shape the neck 50 of the first body glass container 5.

If necessary, the pressing step described below is followed by a blowing step, during which the bowl portion 8 is deformed by insufflation in its internal volume. This blowing step can increase the internal volume of the bottle of the order of 10% to 20% approximately, if one wants to maintain the geometric features of the internal surface, obtained during the pressing step. The term "pressed" used here refers to any implementation including a pressing step, including the case where it is followed by a blowing step, as long as the other requirements of the invention are met.

The neck 50 is completed during a trepanning step generating the opening opening in the neck.

The second glass container body 6 can be produced by the same method, using the same installation, in which case the first and second glass container bodies 5, 6 will have identical shapes, in particular symmetrical with respect to the interface plane, or with different installations, in which case the first and second bodies of glass containers may have different shapes, in particular symmetrical with respect to each other with respect to a plane of symmetry, or whose mouths are symmetrical one relative to each other with respect to a plane of symmetry.

As shown in FIG. 2, the first glass container body 5 and the second glass container body 6 are joined to the closure system. In particular, the first glass container body 5 is assembled to the sealing system 13. This assembly can be made by clipping. During the clipping, the flange 23 is deformed elastically by the peripheral bead 11 during the relative movement of the first glass container body 5 and the closure system, until the bead 25 enters the rib 12, this makes it possible to release the stresses previously generated in the wing 23. For example, the first glass container body and the sealing system 13 are translated towards one another in an assembly direction, but an assembly progressive along the periphery of the mouth is also conceivable.

We can then assemble the second glass container body 6 to the sealing system 13 (itself already assembled to the first glass container body 5). We can proceed in the same way as above, for example by clipping.

Where appropriate, the first and second glass container bodies 5 and 6 are simultaneously assembled on the sealing system 13.

The sealing system 13 is considered in one piece, that is to say that it is made by a single piece, one or more piece (s) overmolded by a joint, or a system comprising the part or parts ( s) and the seals compressed between the piece and the corresponding glass container body. Alternatively, one could realize the two-piece sealing system, each providing a tight connection with a respective glass container body, and then assembled tightly together; this embodiment may allow, among other things, to decouple the shapes of the mouths of the first and second bodies of glass containers and to allow asymmetrical assemblies. Then we assemble the locking system 14 to the assembly previously assembled. In particular, it surrounds the sealing system 13 with the locking system 14. For example, it has the band 37 having two free ends. The sealing system 13 is surrounded with the band 37 and a traction is applied on the band until a satisfactory tension is obtained, then the two end portions of the band are secured together in this position, so as to maintain the band 37 stretched.

A receptacle of the desired product may be filled. The content 3 is then directly in contact with the glass body of the receptacle and the sealing system 13. Then the receptacle is closed by assembling a dispensing member on the respective neck, and the same is done for the other receptacle.

The two products distributed may differ from each other by one and / or the other of a number of characteristics, such as their chemical composition (nature or proportion of constituents), their density, their factor of dilution, their viscosity, ...

In a variant, the bottle forms a single receptacle. In this case, it contains a single product to distribute. A product to be dispensed as unique is a product which may contain a mixture of several chemical compounds, but of sufficiently controlled composition, for example homogeneous, in the bottle, for the intended application. It suffices that the body 15 has a through opening allowing the circulation of the contents 3. In such a case, it is also possible to use only one dispensing member 51. For example, two glass container bodies 5, 6 of similar interfaces are produced, but different in that the first glass container body 5 comprises a neck 50 as previously described for assembling a dispensing member, but the second glass container body 6 comprises only one opening, at the mouth 9 '(in this example, the second glass container body does not include a neck 50' or an opening 49 '). An exemplary embodiment is shown in Figure 6. The mold used to make the second glass container body is shown in Figure 4a. It differs mainly from that of Figure 4 by the shape of the bottom of the body cavity 45 adapted to not form a neck 50 '.

In such an embodiment, it is also possible to install an object, for example decorative, inside the bottle. The object is for example fixed rigidly to the closure system, in particular to the sealing system, in particular to the body 15 thereof. The object is of dimensions not allowing its exit by a product dispensing opening, but allowing its installation through the mouth of the body glass containers.

Figure 7 illustrates a similar embodiment, in which the glass container bodies 5, 6 have very different shapes. The glass container body 6 comprises, for example, a bowl portion 8 having a generally cylindrical shape of revolution, and the glass container body 5 comprises, for example, a bowl portion 8 having a general hemisphere portion shape, so that their respective large mouths may have a similar annular shape. Thus, according to the examples, at least two glass container bodies have one or more (when they are compatible) of the following characteristics:

an identical external form,

an outer shape symmetrical to each other,

- an external form different from each other,

an asymmetrical outer shape of each other,

- an identical inner form,

- an inner shape symmetrical to each other, - an inner form different from each other,

- an asymmetrical inner shape of each other,

- a volume identical to 10%,

- a different volume of at least 10%,

- a different volume of at least 50%,

- identical exterior decor,

- different exterior decor,

- an identical interior decor,

- a different interior décor

FIG. 5 represents an alternative embodiment of the embodiment of FIG. 1. In this example, two receptacles are also provided assembled to one another in a sealed manner. The dispensing system 4 is a combined dispensing system simultaneously addressing the two receptacles. The first and second product outlets 52, 52 'are carried by a common actuator 54, and are respectively connected to each of the receptacles via a conduit. The locking piece 36 may be provided locally with an opening for mounting the dispensing system.

An implementation of the dispensing system is shown in FIG. 5a. The dispensing system 4 is assembled directly on the glass container bodies 5, 6. For example, as is already known, for assembling a dispensing member to a glass container. The first glass container body 5 has a neck 50 which is made as typically a glass neck on a glass container body. The neck 50 is formed in a peripheral wall of the first glass container body. The dispensing member 51 is assembled on the neck 50 in an appropriate manner, for example by crimping, snapping or screwing. The same can be done for the second glass container 6, which has a neck 50 'on which is assembled the dispensing member 51'. For example, one proceeds to the same kind of assembly as for the first dispensing member 51 on the first glass container body 5. For example, the necks 50, 50 'and, consequently, the dispensing members 51, 51' , are provided symmetrically with respect to the median plane of the vial 1. If combined actuation of the two distribution members 51, 51 'is provided, as shown in FIG. 5, a common cap may be used. The two dispensing members 51, 51 ', each associated respectively with one of the necks, with a common cap, are capped. The actuation of the common cap by a user allows the simultaneous actuation of the two distribution members 51, 51 '. The actuation of the common cap by a user prohibits the independent actuation of the two distribution members 51, 51 '. Although it has been shown above, for the combined distribution embodiment of the two products, a distribution system comprising two product outlets 52, 52 ', it would be possible alternatively to provide a single product outlet connected to each of the two dispensers. receptacles.

Alternatively, it can provide independent actuation of the two distribution members 51, 51 '.

In this example, there is also shown a decorative object 59, 60 provided in each of the receptacles.

As can be seen in FIG. 4b, it is possible to manufacture the glass container body 5 with the aid of a mold similar to that of FIG. 4. If the neck 50 to be formed is placed in a place that does not allow the punch to be demolded. 47, using a dedicated neck punch 63, mounted movable relative to the body cavity 45. Where appropriate, it is one of the portions of the large opening impression 46 which incorporates the formation of the neck 50 . According to a variant of the dispensing system 4 for the embodiment of Figure 5, it is not necessary to make necks in the glass container bodies 5, 6, but in the sealing system 13 locally formed for this purpose.

The variants described above to provide the dispensing system at the closure system can also be transposed to the case where the bottle has only one receptacle (in which case, there is only one neck). FIG. 8 proposes a bottle comprising a first glass container body 5, comprising a mouthpiece.

The bottle comprises a first closure system 7 assembled at the mouth of the first glass container body 5 in a sealed manner.

The bottle comprises a second glass container body 6 assembled to the first closure system 7 in a sealed manner. The second glass container body 6 comprises two large mouths. The mouths are opposed to each other. The second glass container body is for example an annular cylinder open at both ends. The geometries of the inner and outer surfaces may vary from the illustrated example. The first mouth of the second glass container body is assembled to the first closure system 7 in a sealed manner. The assembly constituted by the first closure system 7 and the first and second glass container body 5, 6 substantially corresponds to this set of parts as described in Figure 6, except that this set comprises a large open mouth.

The bottle comprises a second closure system 61 assembled to the second mouth of the second glass container body 6 in a sealed manner. The second closure system 61 can be made as a half-closure system 7, its sealing member optionally comprising a neck on which a dispensing member 51 can be assembled. If necessary, it is possible to replace, for this closure system, the locking system 36 encircling the sealing piece by an assembled gripping piece 64, for example clipped from above, and having a through opening 65 allowing through it the neck 66 carrying the dispensing member 51, as shown in FIG. 9.

Thus, the second sub-bottle 106 does not consist of the single glass container body 6, but comprises a glass container body 6 sealingly joined to a closure system 61. The first and second closure systems and the glass container bodies are assembled permanently immovable so as to define at least one receptacle.

The product dispenser member provides access to a product that may be contained in the receptacle. Alternatively, if appropriate, it may be realized elsewhere than in the second closure system, as described above for the other embodiments. If necessary, alternatively, according to what appears to be another invention, if the first closure system 7 is closed, it is not necessary to use the glass container body 5.

In the embodiments shown, the glass container bodies 5, 6 and the closure system (s) 3, 61 are permanently assembled and irremovable. By "permanently" and "irremovable" it is meant that the closure systems 3 can not be disassembled from the glass container bodies under normal conditions of use.
