Description

The present invention relates to a glass bottle, in particular quartz or crystal glass or ceramic glass (stoneware, porcelain, some glasses, etc.) intended in particular for the packaging and distribution of products cosmetics such as perfumes.

Most perfumes are packaged in glass bottles, obtained in particular by blowing, or by molding. Such bottles have typically a closed body surmounted by a collar connected to the body by a shoulder and defining an opening for the outlet of the product. The collar may have a thread on its outer surface able to cooperate with the internal thread of a plug. Alternatively, on the neck is mounted, in particular by crimping, a pump or a valve capable of being actuated by a push button. To this end, a bead is provided in the vicinity of the opening delimited by the neck so as to allow crimping of the pump or valve. Alternatively, the pump or the valve can be mounted on the neck via an intermediate element mounted force into the neck of the bottle. In this latter hypothesis, mounting by force of the intermediate element weakens the neck and prohibits very tight mounting.

Some glass bottles have at least part of their surface cut and polished facets or other reliefs, improving the aesthetics of the bottle. Of such facets, typically produced by a cutting wheel, can be located especially on the shoulder, near the neck. In this last hypothesis, the neck is inevitably ground or broken, by the tools used to make the different operations at the desired locations. The collar can then be glued so as to allow the mounting of a plug or a pump. However, the bottle has a fragility in the squeeze area. Additionally glue can, in addition to its degradation over time, interact with the product contained in the bottle, which can then significantly affect the properties of the product.

Patent applications EP-A 079 275 and EP-A-0 186 548 describe adaptation assemblies intended in particular to be mounted on bottles in glass, of the neck type, in order to receive a stopper for example. Such sets are composed of a two-piece arrangement, which arrangement implies for its mounting the presence of a collar. In addition, the cost of this two-piece adapter substantially increases the cost of bottle. Finally, in these documents, the adaptation assemblies, by their configuration, exclude mounting of a threaded plug or pump, or minus, require the addition of an additional mounting piece.

Such products may also be contained in vials in ceramic, in particular porcelain, stoneware, or certain glasses. Vial undergoes various treatments, in particular baking or enamelling to make it waterproof, or for decorative purposes. These operations, especially cooking, may slightly modify the characteristics dimensions of the bottle, in particular at the neck, which modifications make it difficult to tightly fit a screwed or retracted plug force, or pump.

It is therefore an object of the invention to be able to produce a bottle, in particular glass or ceramic, not having the drawbacks discussed above.

It is in particular an object of the invention to produce a bottle, using materials as described above, it being possible for said bottle to be particular in the vicinity of the opening delimited by the shoulder, of a treatment including mechanical (cutting, polishing, grinding) or thermal (baking), and on which is mounted in a perfectly sealed manner, a closing device and / or of distribution.

Other objects will appear in detail in the description which follows.

According to the invention, these objects are achieved by producing a bottle made of glass material or ceramic, consisting of a body with a bottom and surmounted by a shoulder delimiting an opening in a plane substantially flush with the shoulder, an insert made of a material of a different nature from the material forming the bottle, being tightly mounted in said opening, for sealingly receiving a closure and / or dispensing element of a product contained in the bottle, said insert having a channel in communication with the bottle, and opening on the outside of the bottle on an orifice Release.

Advantageously, in particular when it is a question of mounting a screwed closure, or a pump, said insert has a portion which emerges outside of the bottle substantially out of the plane of the opening. The bottom, can form a single piece with the body, or be formed from an insert made of material thermoplastic for example. The opening can be located in the axis of the bottle or to be off center.

A bottle, in particular made of glass, is thus produced, the aesthetics of which can be chosen. at will, and which has an insert which can form a neck, mounted perfectly sealed without generating a zone of fragility, and on which can mount any type of sealing and / or distribution means. The mounting the insert does not require the use of glue which can degrade or harm the properties of the product it contains. Furthermore, in the case of a forced assembly of the added element, the constraints linked to this type of mounting, are exercised opposite the shoulder, which shoulder constitutes a area significantly more resistant than a glass neck. Advantageously, the element added is force-fitted into the opening delimited by the shoulder.

The bottle may be made of glass, in particular a crystal or quarter glass, and of which at least the shoulder has cut facets or other reliefs.

The insert can be made of thermoplastic material, such as a polypropylene, polyethylene, polyethylene terephthalate, etc.

The insert can be covered over at least part of the height of the portion emerging from the bottle, of a metal or plastic covering. This characteristic is particularly suitable for the closure described with reference to third embodiment described below.

Advantageously, the added element has on its outer surface, a shoulder or bead capable of imitating the insertion of said element during its insertion in the opening of the bottle.

According to a first embodiment, the added element comprises on the surface outside of the portion emerging from the bottle, a thread capable of cooperating with a corresponding thread of a closure and / or distribution element.

According to a second embodiment, the portion emerging from the bottle has a free end, said free end forming an annular bead so as to allow the crimping of a pump or a valve, controlled by an actuating means in the form of a push button. The set can then be covered with a removable cover.

According to a third embodiment, the bottle has a stopper, one of which central portion is adapted to be inserted in a sealed manner inside said channel through said outlet. The cap may be made of metal, the portion advantageously being central, over at least part of its height, covered with a cladding made of thermoplastic material capable of improving sealing with the channel formed in the insert.

The product can be a cosmetic product, in particular a perfume.

• la figure 2 illustre un second mode de réalisation selon l'invention ; et
• la figure 3 illustre un troisième mode de réalisation de l'invention.

The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:

• FIG. 1 represents an exploded view of a cut perspective of a first embodiment of the bottle according to the invention;
• FIG. 2 illustrates a second embodiment according to the invention; and
• FIG. 3 illustrates a third embodiment of the invention.

The bottle 1 illustrated in Figure 1 is made of crystal glass and has a body 2, closed by a bottom 3, the body being surmounted by a shoulder 4 substantially flat, and delimiting an opening 5 located flush with the shoulder. The bottle is traditionally made by blowing, and is then cut, especially on the entire surface formed by the shoulder 4, so as to form facets 6 whose number, shape, and dimensions are chosen according to the aesthetics sought. The facets are then polished. The collar, present initially on the bottle, resulting from blowing, is removed, during the size operation facets 6. Such facets can also be produced in the vicinity from the bottom 3.

In the case where the bottle is obtained by molding a pressed glass, the body is closed by an added base made of thermoplastic material for example, which bottom can be force-fitted into an opening delimited by the lower edge of the body.

An insert 7 is forcibly mounted in the opening 5 after running in of said opening 5. The insert 7 is in the form of an annular element crossed by a channel 9 of constant section, opening to the outside of the bottle, on an orifice 10 delimited by a first free edge 11 of the insert 7, and at inside the bottle, on an orifice 22 delimited by a second free edge 23 of the element 7. A shoulder 12 is formed by the external surface of the element 7, substantially at mid-height thereof, so as to form a stop capable of limit the insertion of the element 7 into the opening 5.

Element 5 is obtained by molding of thermoplastic materials such as polypropylene or polyethylene. Still other materials can be used.

By way of indication, the element 7 has an axial height of between 10 and 20 mm. The thickness of the wall of the shoulder at the opening 5 is of the order from 5 to 7 mm. The part emerging 13 out of the bottle has an axial height varying between 3 mm and 10 mm, depending on the closure and / or distribution device to mount on the bottle. The walls of the insert, in particular in its part emerging from the bottle, can be up to 5 thick mm. Such a thickness, compared to the thicknesses of the necks of the glass bottles traditional, allows a more solid and waterproof assembly of the element shutter or distribution element. This is particularly advantageous when the closure element is forced into the element channel reported.

A covering 14 is provided so as to cover substantially all of the part emerging from element 7. This covering may be made of metal or plastic, and be maintained on element 7 by gluing, snapping, or self-tightening mounting.

A plug 15 is provided for removably closing the orifice 10 defined by element 7. In this version, the cap has an upper part 16, serving as a gripping member, and a lower portion 17 of such diameter that this part can force into channel 9. According to a mode of particular embodiment, the cap is made of metal, the smallest part diameter being covered with a plastic sheathing 18 capable of improving the seal when the cap is closed. It should be noted that, in this embodiment, in due to the type of mounting of this plug, it is not necessary that the element reported emerges significantly from the bottle.

In the embodiment illustrated in FIG. 2, the added element 7 is shaped slightly different. In fact, according to this embodiment, the portion emerging 13, located above the bead 12 present on part of its external surface a thread 19 adapted to cooperate with an internal thread 20 provided on the cap 15. The bottle itself, not shown, is identical to that discussed with reference to Figure 1.

In the embodiment of FIG. 3, the free edge 11 forms a bead 24, suitable for allowing the crimping of a pump or a valve 25, by means of a crimping ring not shown. The pump is surmounted by a rod emergent 26 mounted on elastic return means, and intended to receive a push button 27 comprising an outlet orifice 28. A protective cover (not shown) can then be removably mounted to protect the pushbutton.

In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. Obviously there may be variations made without departing from the spirit of the invention as claimed below.
