Description

PACKAGING DEVICE FOR A COSMETIC PRODUCT AND ASSEMBLY OF THE DEVICE USING A TWO-SIDED CONNECTOR

INTERNAL FIXATION

FIELD OF THE INVENTION

The present invention relates to the field of packaging containers allowing good conservation of the product, in particular cosmetic or perfume product, and more particularly the field of glass containers. The product can be liquid or viscous, which typically facilitates its recovery / distribution, especially if the container includes a dispenser assembly.

The invention relates here to a container which has an internal container serving to directly contain the product (for example of cosmetic or similar type), and an external glass container making it possible to house the internal container internally, this external container combining the functions of covering the container and receiving, directly or indirectly, an upper covering element or a cover that can be used to close the container after the consumer has taken the product for the first time. The invention also relates to a method of assembling the container by using an adapter connector or coupler which makes it possible to space the internal container laterally from the external container.

TECHNOLOGICAL BACKGROUND OF THE INVENTION

It has long been known, as illustrated for example by document FR 1573885, to use external glass coverings in cosmetic product packaging devices, while receiving the product in an internal container, typically made of plastic. However, the use of an internal plastic container can pose problems of chemical compatibility with the product to be packaged. Polyethylene and polypropylene are then the only choices for making such an internal container. There is therefore a need to improve the chemical compatibility of the internal container with the product, by improving the preservation of the latter, and to limit the use of a disposable plastic container.

In addition, it would be particularly advantageous to be able to easily refill the container with product, typically without throwing away a plastic container and minimizing the amount of plastic to provide the interface between the containers.

Interfaces are known from document FR 2878835 A1 for assembling an internal container which may be made of glass with a covering container covered on the inside with a lining, in order to obtain a fluid dispenser assembly which makes it possible to produce refills. However, the type of assembly shown in this document is relatively complex, which limits its application and reduces the possibilities of an aesthetic effect (we do not take full advantage of the properties and performance of glass). Also, there is a growing need for miniaturization of packaging containers, in particular to facilitate mobile use. The type of assembly presented in document FR 2878835 A1 does not make it possible to produce at a reasonable cost robust containers whose width is reduced (typically less than 40 or 50 mm for the largest dimension), in a production context. reliable and at high speed.

In addition, there are solutions with an annular elastomer insert in applications far from the cosmetic field, in order to mount a reservoir inside an external glass container. However, the use of rubbers or elastomers makes recycling more difficult (thermosetting plastics having crosslinks). This limits the application of this kind of insert.

It would therefore be interesting to better integrate an internal container, possibly associated with a dispenser assembly, by a packaging device which can meet both many desirable technical requirements for ease of assembly and disassembly while also being able to integrate many types of glass coverings and to limit disposable plastic parts when the inner container / reservoir part forms all or part of a replaceable cartridge.

OBJECTS OF THE INVENTION

In order to improve the situation, a device for packaging a fluid product is proposed, comprising:

- a glass body which is hollow and provided with a bottom or a lower edge at a lower end of the body;

- a reservoir part which comprises a glass container delimiting an internal volume of the reservoir and extending, in an insertion position, into an internal volume delimited by the body, the container having a longitudinal axis and an opening on the side d an axial upper end of tubular shape; and

an annular connector formed in one piece and delimiting a hollow interior space, the connector having at least a first portion defining a first internal face on which an upper end of the body is fixed, preferably without the possibility of rotation; with the particular feature that the upper end of the body has an outer circumferential face provided with at least one relief or anchoring profile to define a peripheral fixing region and to engage against said first inner face, the connector surmounting the body made of glass by a radial portion connected to at least a first portion, knowing that the connector includes a second portion defining a second internal face delimiting the hollow interior space and capable of retaining said container in the insertion position by at least direct radial contact against an annular outer surface of the container, to allow removable attachment of the reservoir part, the second portion of the connector being separate from the radial portion.

The insertion position of the container is preferably obtained by inserting the container into said interior volume of the outer body by passing through the connector via the hollow interior space. The insertion position of the container forms a final / functional position.

Thanks to these arrangements, it is possible to easily integrate the glass container inside the outer glass body, typically without radial glass-glass contact. With such a connector, two contact / fixing zones formed by glass walls are directly covered (by a single piece).

The connector covers the upper edge of the body, with its radial portion, and also cooperates with (by covering it) the region forming the coupler of the body, through its first portion which can descend lower than the radial portion. In the assembled state, the container is visible only through the outer body, if the latter is made of transparent glass: the container is therefore an inner container even if it includes one end having a filling opening which typically protrudes. the level of the upper extremity of the external body. In what follows, this container alone forms a reservoir of the device and the container is thus packaged in direct contact with a side glass surface. Although a single-compartment container is typically provided, without a partition or follower piston, it is understood that the internal structure of the container is not limiting as long as this container functions as a reservoir.

According to the present invention, it is possible to provide a container which can be aesthetic and capable of effectively preserving the contents by facilitating assembly. It is also allowed a great flexibility in the final assembly, the product being able to be already present in an internal and sealed cartridge (for example via a crimping on the top of the internal container), or not, before the insertion in the external container. .

Flexibility is also obtained for the choice of the material of the annular connector, since the stresses exerted on this material can be advantageously minimized. In some options, it is possible to form elastically deformable portions delimited between slits or formed in thinning zones, being able to avoid placing the inner container in continuous annular contact with the connector, which facilitates the extraction of the part to be removed. tank, in case of replacement for example.

In other words with this arrangement, the connector is well suited to immobilize the containers (internal and external) between them, without undergoing significant compressions. In preferred embodiments, a radial movement is allowed only at the level of the deformable contact portions, knowing that the complementary portions of the connector coming to surround glass surfaces (of the container interior and / or of the external body) are preferably more rigid to allow it to come into abutment axially against reliefs, threads or other anchoring profile of the peripheral fixing region.

The opening of the container can be closed by an upper part closing the reservoir part, for example by being directly connected to this reservoir part. This upper part may be an assembly or head for dispensing the product, preferably forming a metering assembly comprising a metering pump and a movable actuating portion to allow the distribution of the fluid product.

- The upper end of the body has, in the peripheral fixing region, only protruding reliefs by a nominal surface level which goes around the neck.

- The upper end of the body has, in the peripheral fixing region, radially projecting reliefs which do not exceed by more than 5 mm a nominal surface level which goes around the neck or similar upper end of the body.

- the final insertion position of the container is optionally locked in the axial position, by a first axial bearing of the container against the bottom of the body or against at least one stop element formed in the second internal face, combined with a second axial bearing of the container, in the direction opposite to the first axial support, against a stop relief delimiting under it a housing for a gripping edge directly formed on the outer surface of the container.

- the first internal face is provided with at least one elastically deformable portion, delimited by slots or recesses in the thickness of the outer skirt, which is adapted to come into engagement by elastic return effect radially inwards in said peripheral fixing region and axially lock said insertion position.

- the body is a glass bottle made in one piece and including the peripheral region for attachment to a portion of the lateral surface of a neck adjacent to a shoulder of the bottle, the space between the bottle and the container being empty of product.

the at least one flexible portion, preferably produced in the form of a portion with radial outward movement, is thinned with respect to the rest of the outer skirt. - There are provided, in the peripheral fixing region, two groups of axial abutment members co-acting to maintain at a predetermined axial level and / or in a predetermined angular position at least one member projecting inwardly provided in the outer skirt, the axial stop members of one of the groups pushing the at least one flexible portion radially outwards.

- The radial part of the connector a transition part between the tubular outer part of an outer skirt radially distal to the outer surface of the container, and an upper sleeve radially proximal to the relation to the outer surface of the container.

- The tubular outer portion and the upper sleeve extend coaxially in respective opposite axial directions from the radial portion, parallel to the longitudinal axis.

- The body and the connector define a receiving compartment of the receptacle, the height of which is less than the height of the receptacle. - the opening at the axial upper end of the container is closed, in a zone axially spaced from an upper edge of the connector, by a dispensing assembly forming a metering assembly comprising a metering pump and a movable actuating portion for allow the dispensing of the product contained in the container (which is in the insertion position), whereby the device constitutes a device for packaging and dispensing the product.

Optionally, the packaging device may allow dispensing using a metering assembly which, directly or via an attached stopper element, seals the axial opening of the inner container. This is then very suitable for the various requirements of the practice (in particular the sealing requirement) and the connector is compatible with very different covering options (possibility of hanging the container, of forming an external body domed outwards , to use any type of external section (square or rectangle, polygonal, oval, circular, etc.) while allowing disassembly which does not affect the integrity of the distribution circuit.

In case of replacement of the reservoir part or of a cartridge including the container, at least the outer body, a cap and / or an upper trim element can be reused, preferably by also reusing the connector.

In the event of a replacement for a replacement of the internal unit, operations are easy, requiring no tools when the container is held by friction, screwing or similar coupling. It is clear that no disassembly action interferes with sealing parts of the internal unit / cartridge.

It is allowed to include the inner container in a functional part of the device which is entirely internal (internal unit), knowing that it is sufficient to mount a dispensing head, of which for example a dosing assembly is part, on the part to tank which essentially includes the container. This functional part, which meets the waterproofing requirements, in particular in the cosmetic or pharmaceutical field before and even after the first use, can be designed separately. The functional part can thus be produced in a very large number of copies (of the order of several million for example), while being integrable in a personalized device (in its format and in the choice of the material of the body) thanks to the possibility of covering the connector and the container respectively with an upper covering element and an external body, and possibly by dimensioning / adapting the connector.

In addition, the user has the direct possibility of extracting the reservoir part or any internal unit / cartridge from the body since the latter can move upwards, without any retaining effect by the hollow body, only the connector being able to move upwards. exert a restraining / blocking effect.

In some options, the removal of the indoor unit may involve only a longitudinal sliding of the inner container in the inner hollow space, along the second internal face of the connector. In this case, the second internal face may have tapered reliefs / the width of which decreases as it approaches an upper outlet of the connector.

In some options, removal of the internal unit may also involve relative rotation of the inner container with respect to the second internal face of the connector, for example when it is sufficient to unscrew to extract the internal unit from the body. Also in this case, the internal unit is axially movable and can be easily removed from the hollow body, without tools or delicate unclipping operations.

In various embodiments of the device according to the invention, one of the following provisions or a combination of several of the following provisions may be provided:

- the body, an upper trim element surrounding the connector and optionally the cap give the device its external shape in a storage configuration.

- The body has a flat upper face, without relief or annular projection on this upper face.

the outer glass body has at least one groove region or a lateral cavity for receiving an internal lug included in the connector fixing means (on the second internal face of the connector), the groove region or lateral cavity being an external cavity (opening radially outwards) delimited axially between a set of external reliefs / ribs and an external shoulder.

- When a lateral cavity is provided, this extends circumferentially between a termination zone or is formed a stop surface having a radially outer edge and a section narrowing access duct; the access conduit has an entrance for a tang moved tangentially around / along the annular groove between a top relief / rib and the shoulder.

- there is in the lateral cavity at least one protruding relief relative to a bottom surface of the lateral cavity, knowing that a relief constitutes a notch whose height (measured from the bottom surface) is less than a depth of the cavity measured from the radially outer edge of the abutment surface delimiting said cavity (between this edge and the bottom surface).

- Each of the reliefs can be designed and arranged to oppose the unlocking of the removable fixing between the connector and the body.

- a locked configuration is obtained when each internal lug is placed in a corresponding lateral cavity, extending on either side of the abutment surface of the cavity, beyond the notch of the cavity; this arrangement with a groove of discontinuous depth, and relatively elongated lugs, using at least two lateral cavities, secures the attachment and prevents accidental disconnection.

According to one feature, the first internal face of the connector has first fixing means which cooperate with second fixing means directly formed in the glass wall of the body. For example, these first and second fixing means form a bayonet type connection system. This arrangement makes the binding both robust and easy to unlock.

Typically, the first fixing means are formed on an inner face of the connector, preferably on the inner face of a tubular outer part or skirt, in an annular zone which is located lower than (entirely below) the radial portion in the locked configuration of the connector (in which the latter is integral with the body).

Optionally, the connector has at least two internal lugs, intervening to make the bayonet type connection.

The connector may also have axial slots, in the same generally tubular outer skirt, belonging to said connector. The axial slots make it possible to obtain an axial movement in the skirt, which facilitates the assembly and disassembly operations.

Such slots can advantageously be hidden by an annular part, for example a part forming a hoop, which surrounds the outer skirt or even the entire connector.

Optionally, the connector can have, in the outer skirt:

- at least one flexible portion, preferably in the form of a portion with radial displacement towards the outside, which is preferably thinned with respect to the rest of the connector, knowing that all or part of the first fixing means are located in the 'at least one flexible portion.

When the connector has axial slots, in the same outer skirt of generally tubular shape (skirt belonging to the connector), each of the slots is preferably designed to separate a flexible portion of the skirt from an adjacent portion of the skirt which is more rigid than said flexible portion.

The part forming a hoop may optionally be overmolded on the connector. It is understood that this part may, in a state at rest of the flexible portions, extend radially outwardly from each of the flexible portions. Optionally, the part forming a hoop has an anti-rotation relief or an internal collar or similar section reducing the upper opening of the part, adapted to engage with at least one relief included in the part constituting the connector. More generally, it is possible to form a means for blocking a relative rotation between the connector and the auxiliary part or similar upper covering element.

Preferably, the upper opening of the body has a diameter which is substantially close to an external diameter of the container, for example without exceeding this external diameter by more than 2 mm. This optimizes the volume / capacity of the device, minimizing dead volumes, the peripheral volume can be reduced to a minimum.

According to another aspect, there is provided an assembly method for obtaining the packaging device according to the invention, by mounting the glass container in the outer glass body using a connector provided as a part of the glass. insertion between the outer body and the container, the method comprising the steps consisting essentially of:

- coupling the annular connector made in one piece around the peripheral fixing region of the outer body which is formed on an outer circumferential face provided with at least one relief or anchoring profile, the coupling of the connector being made in extending from above the outer body, so that at least the radial portion of the connector surmounts the body, the coupling being achieved by fixing the first inner face of a first portion of the connector to the peripheral fixing region of attachment which is provided in a neck of the body, this neck making it possible to delimit the upper axial opening of the outer body;

- Mount a reservoir part, including the glass container, in the interior volume of the outer body through the axial opening of this body and through a hollow interior space delimited by the connector; and

- Removably fix the reservoir part by placing the container in an insertion position of the container, after the assembly of the reservoir part, insertion position in which the second internal face of a second portion of the connector, tubular and distinct from the radial portion, blocks the container in position by a plurality of direct radial contacts against an outer lateral surface of the container.

Thanks to this type of assembly, blocking is enabled by a single piece by direct contacts against two contact / fixing zones formed by glass walls, respectively of the outer body and of the container.

According to one aspect, there is also proposed a kit for the packaging and distribution of at least one fluid product, comprising:

- said packaging device according to the invention (with a body, a cartridge and a connector optionally surmounted by a cap), the container forming part of a first cartridge, filled with a product stored in the container; and

- a second cartridge filled with a product identical to or different from the product contained in the first cartridge, the second cartridge including a container identical to the container of the first cartridge, knowing that the container of each cartridge is adapted to occupy the same insertion position in the external body of the device while being held in this insertion position by a fastening produced by the second internal face of the connector.

The cartridge can advantageously be an internal unit protected by the body and the connector (which can itself be covered by a band or other element. cover), and optionally by a cap. A container-connector fixing configuration can optionally be locked and be obtained by using removable fixing means formed in the second internal face. The same part constituting the connector can advantageously integrate, on the same interior side, one or more internal members with an anti-rotation effect with respect to the body and also makes it possible to block the position of insertion of the container.

DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

In the various figures, the same numerical references designate similar elements of the various exemplary embodiments shown and described.

As shown in Figures 1, 2 and 8, 9 and 11, the packaging device 1 comprises a body 2, typically a bottle body, with a bottom 2a which defines a support base, a container 4 which extends (essentially or in part) inside the body 2 and makes it possible to store the product PF (see FIG. 11) which is typically liquid or viscous to be dispensed, a connector 5 or 5 'which is here made from a single part and which is mounted on a top of the body 2, and a dispensing head 6. A cover or cap 16 may be provided to protect and typically hide the dispensing head 6.

In the figures, the respective axes X and X ’of the inner container (container 4) and of the outer container (body 2) are placed vertically. These containers are separate and can therefore be designed separately. In the figures, the up, down direction is defined along the direction of the longitudinal axes, so that a direction of the width of the container 4 or of the body 2 is a radial direction and a direction of the height of the container 4 or of the body 2 is a longitudinal direction.

As can be seen in FIG. 1, the outer lateral parts 1b and 1c of the device 1 have a continuity of geometry and of section (substantially identical dimensions) in the zone surrounding the container 4 and the dispensing head 6. The cap 16 typically forms a complementary outer lateral part 1a which also extends these outer parts 1b and 1c, with continuity of geometry and section. The outer part 1c is here formed by the body 2 of glass, so that the device 1 is of the type with an outer wall of glass. The container 4 is also a piece of glass, preferably of glass drawn in order to have a thin and typically transparent wall. The thickness e4 of the container 4 is for example less than or equal to 1.5 mm, preferably less than or equal to 1 mm.

As can be seen in FIGS. 1 and 12 in particular, the dispensing head 6 may be of a type known per se, for example including a diffusion member 14 integrated laterally in the pusher member 10 or 110 of the dispensing head. A dip tube T can extend internally into the container 4 to draw the product PF as close as possible to the bottom 4a and bring it to a metering chamber internal to a pump body. The assembly or distribution head 6 can make it possible to distribute doses, for example by including a metering assembly of the type having the metering chamber provided between the tube T and an outlet included in the diffusion member 14.

It is possible here for the outer lateral part 1b which directly extends the part 1c to be formed by a lower lateral face F8 of an upper covering element 8, 108. In the embodiment of FIGS. 1-2 or of FIG. 9, this element 8 can optionally form a support for the cap 16. Such an element 8 enables the connector 5, 5 'to be covered laterally as well as a stationary part 6a of the dispensing head 6 and the upper end 4d of the container 4. .

The upper covering element 8 is optionally provided with one or more fixing members (not shown) of the cap 16, preferably provided on a sleeve 18 radially recessed with respect to a skirt J8 of this element 8. The fixing of the cap 16 may also result from a correspondence of shape and / or dimension, for example with a simple effect of friction. The skirt J8, of tubular shape, defines the intermediate part 1b, visible from the outside between the tubular side wall 2b of the body 2 and the cap 16. With the cap 16 closed, this sleeve 18 is not visible because it is narrower than the tubular outer part or skirt J8 delimiting the part 1b, and housed in an internal volume of the cap 16.

In the embodiment of Figures 11 and 12, the upper trim element 108 may optionally allow removal of the cap 16 of the removable type. Such an element 108 then makes it possible to cover the connector 5, 5 ', the upper end 4d of the container 4 and the whole of the dispensing head 6 laterally. In this option, the movable part of the dispensing head 6 includes or is actuated by a pusher member 110 operating similarly to the conventional pusher member 10 shown in FIG. 1. Here, the pusher member 110 is able to slide internally along the outer wall of the upper trim member 108 .

As shown in Figure 12, the diffuser 14 forms an anti-rotation protrusion through a slot 130 to prevent relative rotation between the upper trim member 108 and the pusher 110.

It is understood that the container 4 and the dispensing head 6 form a functional whole, usable as a replaceable cartridge 25, 25 ’. This type of cartridge 25, 25 ’constitutes here an internal unit, by not forming any of the external side faces of the device 1. The cartridge 25, 25’ is also typically placed between the bottom 2a of the body 2 and a top of the cap 16.

As illustrated in FIG. 9, it is understood that the device 1, in an operational state allowing distribution, has an external side wall SW. Here this side wall SW is formed by a tubular outer part which surrounds the connector 5, 5 'and by the outer side face of the body 2. This outer side wall SW extends, around the longitudinal axis X' of the body 2, from the lower end of the body 2 up to a shoulder E8 or other upper edge formed in the upper covering element 8, 108.

It will be understood that the body 2, the upper element 108 and optionally the pusher member 110 can be reused with a new cartridge 25, 25 ', after disassembly / assembly operations (the principle illustrated in the diagram of FIG. 9 can be applicable).

Referring to Figures 1 and 2, the container 4 has a width, an external diameter D4 or other external dimension characteristic of the overall width, which allows the insertion at least in part of this container 4 in the volume V of the body 2. The upper end 200 of the body 2 has an annular upper edge 2r which can serve as a stop / support face of the connector 5, 5 ', this edge 2r being in axial contact or directly opposite a portion. radial 5r of the connector 5, 5 '. More generally, the upper end 200 and the connector 5, 5 can be attached to each other, for example by using a first internal face F1 of the connector 5, 5 ". The connector 5, 5 ′ can make it possible to center the container 4 while maintaining this container integral with the body 2, with a radial spacing e45 between the body 2 and the container 4 which does not exceed 2 mm, and which preferably does not exceed not the average thickness of the container 4.

The internal face F1 can be provided in an external skirt 15 of the connector or in at least a similar peripheral portion of the connector 5, 5 ', which is covered externally by the external side wall SW or by a wall of a cap 16 in a assembled state of the device 1. Preferably, the outer side wall SW is heterogeneous, with for example another rigid material constituting the upper covering element, for example in the form of a metal, plastic or other material other than glass .

Non-limiting examples of the geometry of the glass container containing the product and examples of the product

With reference to FIG. 1 and to FIGS. 8 and 11, provision is made to form a product reservoir in a single piece of glass, which consists of the container 4 of rigid inert mineral material. The container 4 can be transparent or opaque in certain options. The glass of the container 4 is well suited to form a chemically inert material (without interior coating or lacquering), allowing contact compatible with a long conservation of a product PF poured / deposited in the internal volume V4 of the container 4. The volume of reception (corresponding to a single cavity here) of the container can be adapted to store the product, cosmetic, pharmaceutical or other product which is typically fluid, semi-fluid or pasty, inside the outer body 2 (at least at the upright condition, upright of the device 1). The container 4 is a single piece of glass, typically drawn glass, generally called a flask or small bottle. The container 4 comprises a bottom 4a and a tubular wall 4b which extends longitudinally around a central axis X, between this bottom 4a and an upper end 4d which defines an opening O of the container 4. This opening O is here an opening for filling with fluid product PF. In some options, filling may be permitted via the bottom 4a, for example via a valve located in the bottom 4a. The wall forming the bottom 4a is for example of the substantially planar type or provided with a rounded or dome (to form a bottom curved downward or upward).

Referring to Figures 1 and 8, the container 4 may here have a collar or flange 40 provided on top of a neck 4c. In order to optimize the capacity of the container, the section of the container may be constant, for example cylindrical, from the bottom 4a to an external portion of the container 4 located outside the internal volume V of the body 2. The metering chamber of the head 6 can optionally extend into the internal volume V4 of the container, for example in an axial zone situated entirely above the upper edge 2r of the body 2 and below the level of the opening O.

The receptacle 4 forms the reservoir part R of the cartridge 25, covered and protected by the body 2 and the connector 5, 5 'possibly completed with a hoop / upper covering element 8, 108, only the operable part of the dispensing head being an unprotected / directly visible outer part (in a cap-less condition 16) of the packaging and dispensing device 1.

When the body 2 is transparent, the container 4 can be seen. In this case, the container 4 may for example have a cylindrical shape. The fill level is visible throughout the duration of use of the device 1.

Provision is preferably made to fill the container 4 with product PF before constituting / assembling the cartridge 25, 25 ', and before sliding the container 4 in the body 2. It is understood that after filling, the head can be mounted. 6 in a pre-assembled state, with the plugging element S (which defines the bottom of this head 6) in a partially closed or non-sealed position, opposite to an actuating part 10 of the assembly / dispensing head 6. A finalization step, for example by crimping, can make it possible to obtain the cartridge 25, 25 '. The circular shape for the receptacle 4 is particularly well suited here to allow the receptacle 4 to be extended axially by a head, the metering assembly of which includes a metering pump 7 which is partly inserted inside the volume V, the along the longitudinal axis X.

Non-limiting examples of the structure of the glass body

The glass used to form the outer body 2 is preferably obtained from silica and typically transparent or translucent. The glass of container 4 and that of the body external 2 can be the same or different.

Referring to Figures 1 and 4, the body 2 has a tubular side wall 2b which extends longitudinally around a central axis X ', which may coincide with the longitudinal axis X of the container 4. The side wall tubular 2b is cylindrical in the option of Figuresl and 4 but may be of square section as in the option of Figure 8. More generally the tubular wall 2b may have any geometry, in particular any type of geometry with a suitable circumference gripping and which exceeds the maximum circumference of the container 4, so as to avoid any radial contact between the container 4 and the side wall 2b.

In some options, the side wall 2b has a cross section whose profile is substantially constant from the lower end to the annular upper edge. Alternatively, the side wall 2b can optionally have a cross section whose profile evolves longitudinally in the direction of a progressive enlargement of the cross section, moving away from the connector downwards. At least one bulge or bulge can also be provided in the side wall 2b.

The body 2 forms an external body of the device 1. This body 2 has a side wall 2b which can extend with continuity of section from the bottom 2a to a shoulder E2 to which is connected a neck 2c delimiting the opening. axial 2d. This neck 2c can have a circular section with an internal diameter slightly greater than an external diameter of an insertion part of the container 4. The base 2a can have feet or any type of support portion on a horizontal support, optionally. ring finger, which allows the device to stand upright on its own.

The thickness of the side wall of the body 2 is typically greater than, preferably at least double, the thickness e4 of the glass wall of the container 4. The bottom wall of the body 2 may be thicker than the side wall. 4b of the container 4. For example, the thickness e of the side wall 2b can be of the order of 2 mm, while the side wall 4b and here, also the bottom wall 4a, have a thickness of about 1 mm.

Referring to Figure 8, the height H2 of the outer body 2, essentially defined by the side wall 2b and the neck 2c, is here less than the total height H4 of the container 4. In other words, whether the container 4 is or not. axial bearing against the inside of the bottom wall 2a, it has in all cases an upper end 4d which projects upwards beyond the upper axial opening 2d of the external body 2.

Referring to Figures 1 and 4, the neck 2c can advantageously be of low axial extension L20. A relatively small axial extension makes it possible to reduce the overlap area between the body 2 and the connector 5, 5 ', and thus to minimize the plastic material required in the design of the connector 5, 5', in particular by reducing the length of a skirt 15 of this connector, visible in FIG. 5 and by reducing, if necessary, the extension of a part forming a hoop or upper covering element 8, 108. By way of nonlimiting example, the neck 2c has a total height or axial extension L20, measured from the shoulder E2, less than or equal to 15 mm.

Furthermore, the neck 2c or other similar type of end 200 may include an outer circumferential face provided with one or more reliefs to define a peripheral RF attachment region, on which the connector 5, 5 ’can engage. In certain variant embodiments, the peripheral RF attachment region may correspond to an anchoring profile, for example a longitudinal profile with section narrowing downward to a shoulder E2 of the body 2.

As illustrated in Figures 1 and 8-9 in particular, the container 4 can be centered relative to the side wall 2b of the body 2. In addition, there is optionally provided a size and shape correspondence between the container 4 and the neck. 2c formed at the upper end of the body 2, optionally by choosing the external diameter D4 of the container 4 which is almost identical (for example identical or very slightly less) than the diameter D 'of the opening 2d, defined here at the level of the upper edge 2r above the neck 2c. The connector 5, 5 'for holding the container 4 can come to rest axially against the upper face of the edge 2c, by its radial portion 5r which makes the transition between two parallel tubular parts of the connector, which will be described in more detail later. .

In a variant, any radially projecting annular relief or any arrangement with radial protrusions, formed on a periphery of the container 4 or other component of the cartridge 25, 25 ', may be suitable to form a contact edge or rim against the connector 5, 5 ', in order to stop the sliding stroke of the container 4, when mounting the container 4 in the body 2.

Non-limiting examples of the realization of the connector and of the assembly of the connector on the external body

Referring to Figures 4 to 7 and 9-10, the connector 5, 5 'is annular and delimits, by a single piece of plastic material, a hollow interior space 7. This connector 5, 5' may have, from bottom to top :

- a tubular outer part or outer skirt 15 provided to surround the peripheral RF attachment region, the skirt 15 having a lower edge B5 delimiting a lower free edge of the connector 5, 5 'which does not extend lower than a shoulder E2 of the connector 5, 5 '(which makes it possible to leave the wall 2b of the body 2 visible, not covered by the connector 5, 5');

- a radial portion 5r which extends annularly around a passage duct with retention of the container 4, making the transition between the outer skirt 15 and an upper sleeve of the connector 5, 5 '; and

- the narrower upper sleeve.

In the examples illustrated, the connector 5, 5 ′ thus integrates a first portion tubular 5a or 150 and a second tubular portion 5b, one of which (portion 5a, 150) makes it possible to directly cover the glass wall of the body 2 including the RF attachment region, and the other (portion 5b) makes it possible to directly cover an annular part of the outer surface S4 of the container 4, in order to retain the latter by a contact zone axially offset upwards with respect to the external body 2. With this contact zone obtained above, it is avoided to increase the spacing or spacing e45 between the upper end of 100 bodies 2 and the surfaces S4 (here a cylindrical surface).

Embodiments of a connector 5 will now be presented, in conjunction with Figures 2 to 8.

The connector 5 has a configuration making it possible to define two stepped internal faces, separated from each other by the radial portion 5r:

a first internal face F1 which can extend entirely under the radial portion 5r and provided with protruding or recessed reliefs 11, 12 forming complementary fixing means of the peripheral fixing region RF, typically without the possibility of relative rotation between the connector 5 and the external body 2;

- a second internal face F2 which can extend entirely above the radial portion 5r and provided with protruding or recessed reliefs R5 forming means for retaining the container 4, here by frictional contact with the external surface S4 of the container 4.

Referring to Figures 4, 5, 6 and 7, the part forming the connector 5 may result from an injected plastic molding. It is allowed, without risk of cracking, to form the connector 5 with thermoplastic materials, such as for example:

- PCTA copolyester (possibly bio-sourced, this material also not being subject to “stress cracking” type cracking), a PET type polyester (recycled or not),

- PC or PK (polycarbonate and polyacetone, possibly bio-sourced type),

- polypropylene, typically of the PPR type - optionally transparent - or even polyethylene.

Such materials are more easily recyclable than thermosetting polymers. PCTA may be preferred for its slightly greater rigidity than polypropylene, which can be an advantage in ensuring the good hold of the assembly (even in case of overturning of the device with the opening facing downwards).

As clearly visible in FIGS. 6 and 7 in particular, the relative rigidity or semi-rigidity of the plastic material constituting the connector 5 does not prevent locally more flexible parts from being formed, for example by thinning the wall in order to reduce the thickness. of material and / or by providing a hinging effect of parts in the form of elastically deformable tabs or tabs 15b, which are delimited between two slots f 1, f2 or similar recesses. In the example illustrated in FIGS. 4 to 7, the first tubular portion 5a internally forming the first internal face F1 is provided with at least one elastically deformable flexible portion SP, preferably two diametrically opposed flexible portions SP. Each of these flexible portions SP forms a tab 15b delimited by slots, here two longitudinal slots f1, f2 placed in the same angular sector which does not exceed 50 or 70 °. It is possible to have the two slots f 1, f2 angularly offset from one another by an angle of between 20 ° and 60 °, preferably between 25 ° and 50 °. When the portion 5a forms a skirt 15 directly connected to the radial portion 5r, the slots f 1, f2 may have a height at least equal to 75 or 80% of the height of the skirt 15.

Typically, in this example as in the type of variant illustrated in FIGS. 9-10, elastically deformable portions SP are provided in the first tubular portion 5a or 150 which are each delimited between two slots f 1, f2 and which bear internal lugs 11 or R1 which will be described later. The material of the outer skirt 15 is chosen to be less flexible than an elastomer, which makes it possible to form in the skirt 15 complementary portions 15a in an arc of a circle (view in cross section) which are relatively rigid and thus not very deformable by radial movement. The elastically deformable portions or tabs 15b can move radially outwards during engagement against complementary reliefs directly formed by the glass of the neck 2c of the outer body 2.

More generally, flexible parts SP can be formed by thinning the skirt 15 and / or by a delimitation between two slots f 1, f2. This makes it possible to obtain a radial movement, in particular towards the outside, of these flexible parts SP, when mounting on the fixing zones of the body 2 which is more rigid than the connector 5; 5 ’, and much stiffer than the SP soft parts. In the examples illustrated, each flexible portion has a reduction in thickness of at least 0.2 mm, preferably at least 0.3 or 0.4 mm, typically representing a reduction of at least 30% in thickness. 'thickness when comparing the average thickness of parts 15a and parts / legs 15b.

In some options, this type of slits f1, f2 can correspond to a pair of digging zones or slit sections which extend and / or meet, these zones being for example located within the same notch (for example notch in "U" inverted or not, or "V").

The part forming the hoop hoop / upper covering element 8, 108 can cover the skirt 15 by attaching to the latter so as to be integral in rotation, around the longitudinal axis X, with the connector 5, 5 '. Referring to Figures 9 and 10, the annular radial portion 5r of the component part of the connector 5, 5 'may be provided with a relief R70 which locally passes through an opening or notch E70 of the corresponding annular radial portion of the element 8 , 108. It will be understood that the connector 5, 5 ', when it is surrounded by a piece forming a hoop 8 or 108, may have at least one anti-rotation relief R70 adapted to abut on a stopper / complementary socket edge (here edge of a notch E70), in order to prevent relative rotation around the longitudinal axis X between the part forming the hoop 8; 108 and the connector 5, 5 '.

The upper part 5b of the connector 5, 5 'can be protected / hidden by the sleeve forming the upper face F8' of the element 8, 108. In embodiments using a cap 146, such face F8 'can be spaced apart. of the cap 16 as visible in FIG. 3 or may alternatively have a lateral friction fixing portion or any suitable means of fixing the cap 16.

In the non-limiting example of Figures 2 to 4, the connector 5 is axially locked in position on the neck 2c, for example after a snap-fit, a screwing or a bayonet-type fixing on the RF fixing region which is devoid of part. flexible. Here, the presence of the flexible portions SP makes it possible to achieve locally a radial separation towards the outside of the part 5a, formed here in the form of a skirt 15 axially connected to the radial portion 5r of the connector 5. The skirt 15 typically covers entirely the neck 2c, laterally, while the radial portion 5r axially covers the edge 2r which extends around the axial opening 2d of the body 2.

With reference to FIG. 3 and to FIG. 5, it can be seen that the radial portion 5r and / or a junction zone between this radial portion 5r and one of the tubular parts 5a or 5b has several recesses or notches 5e, forming for example through openings. Such notches 5e facilitate obtaining a slight hinge effect, here to allow a degree of freedom by radial displacement outward: of thinned portions N5 forming longitudinal external recesses on part 5b (in this case the notches 5e are adjacent to part 5b) and which bear reliefs R5 for retaining the container 4; and / or flexible portions SP or similar portions of the lower tubular part 5a including members 11, 12 which engage the RF binding region.

In other words, one can take advantage of notches 5e of this type to make at least one of the internal faces F1 and F2 more able to conform to the rigid anchoring reliefs formed on the circumferential face of the body 2 covered by the part. 5a tubular. In the examples illustrated, it is the second internal face F2 which benefits from the additional flexibility allowed by the notches 5e, knowing that the protruding reliefs R5 are also entirely formed in regions or panels of part 5b which are thinned.

With reference to FIG. 7, the first internal face F1 is provided with fixing means 11, 12 distributed over its circumference and possibly also distributed in the axial direction. While the inwardly projecting reliefs 11 are here provided in at least two flexible portions SP in the form of tabs 15b, reliefs 12 closer to the radial portion 5r may be provided in the other complementary parts 15a and / or in a region of the internal face F1 interposed axially between the tabs 15b and the radial portion 5r. Here, lugs, pins or similar members 12 for locking in rotation are provided, each placed in a position adjacent to the slots f 1, f2 without belonging to the flexible portions SP. There are four of them here, forming two pairs of locking members 12.

The locking members 12 can here have both an axial stop role opposing a downward depression of the radial portion 5r but also a rotation locking role, operating in pairs to block on two sides each of the two Notches 22. For this, we choose a length L22 of notch 22 (measured transversely, that is to say horizontally, along the circumferential direction of the end 200) which is substantially equal to the spacing on the internal face F1 between two members 22 projecting towards the interior of the same pair PP. Optionally, two notches 22 are provided occupying less than 150 ° or less than 40% of the circumference of the peripheral RF binding region.

The axial retention to prevent the withdrawal of the connector 5 (raising of the connector 5 relative to the body 2) can for example be achieved by the reliefs 11 provided in the flexible portions SP of the skirt 15 or similar elastically deformable tabs 15b, by engagement under a rib 21 or the like of the RF binding region. By way of non-limiting example, the radial dimension of the glass reliefs 21, 22 produced in the peripheral RF attachment region may be greater than 0.2 mm and less than or equal to 0.5 mm.

Referring to Figures 7 and 8, it can thus be seen that some of the projecting members / reliefs 11, 12 provided in the internal face F1 of the connector 5 can engage in at least one annular retaining groove GR2 formed externally in the upper end. 200 of the body 2, in order to axially retain the connector 5. For example, reliefs 11 forming gripping edges, slightly movable by radial movement of the flexible parts SP can overcome an annular rib 21 of the fixing region RF and extend. at least partly in the groove GR2 delimited between the shoulder E2 of the body and the rib 21, for example by making a snap.

Still with reference to Figures 7 and 8, the members 12 for locking / locking in rotation can descend to and possibly beyond the group of at least two notches 22 formed proximal to the free edge 2r of the end 200 and thus perform a rotational locking action. A rotational indexing and / or a positioning indicator may be provided for the operation of fitting the connector 5, which makes it possible to avoid any rotational movement during the insertion of the neck 2 into the interior housing delimited by the skirt 15. or similar lower part 5b of connector 5. More generally, in options not using rotation for mounting the connector 5, it may be advantageous to have at least one rib 21 in the peripheral RF fixing region, allowing clipping or similar axial retention of the part. bottom 5a of the connector 5. With this kind of rib 21, the first internal face F1 of the connector 5 is typically provided with projections or inwardly projecting reliefs 11, 12, which are distributed above and below a region RG groove provided in the first internal face F1 to receive the annular rib 21 or any type of similar complementary protruding relief provided in the peripheral RF fixing region.

In options, the GR2 groove can be located under another GR1 groove closer to the 2r edge. The groove GR1 is here delimited axially between the notches 22 and the rib 21, typically an annular rib continuous here, and extends closer to the free edge 2r than does the groove GR2. The groove GR1 may optionally not contain any relief complementary to the internal face F1 (except possibly the bottom of the members 12, in regions offset with respect to the notches 22), the flexible portion SP possibly having only a single internal relief 11 distal of the radial portion 5r and intended to engage selectively in the groove GR2.

On its outer face, the flexible portion SP may also have one or more outwardly projecting reliefs 13 which may possibly make it possible, in a state covered by the hoop or covering element 8, 108, to limit the maximum radial movement of the flexible portion SP and / or oppose local deformations of the hoop 8, 108 in the event of bearing in a zone of overlap of the flexible portions SP.

Referring to Figures 2 to 4, after mounting the connector 5 on the neck 2c and covering by the part / element 8, 108, the connector 5 is typically axially secured to the outer body 2 of glass. The part 8, 108 can participate in stiffening the connection in certain embodiments, for example by opposing a deformation of the flexible portions facilitating the axial rise and therefore the disassembly of the connector. Generally, each flexible portion SP engages by elastic return effect radially inwardly in the peripheral RF attachment region, here in the groove GR2.

Of course, the assembly allowed with the example of Figures 1 to 8 is not limiting. In fact, FIGS. 9 and 10 illustrate the case of a connector 5 ′ adapted to be coupled by rotation on the neck 2c of the body, with a bayonet-type attachment. Alternatively, screwing can be used, where threads are formed on the peripheral RF binding region. Preferably, it is possible to keep a lower part 150 of the connector 5 'which has a certain radial movement by forming slots to delimit flexible portions and / or by thinning these portions in which the reliefs are formed which engage in the fixing region. RF. Mounting the inner container in its insertion position

In some embodiments, the container 4 is free to rotate around the longitudinal axis X of the container during its insertion into the volume V of the body 2 until it reaches the insertion position. This type of arrangement allows easy assembly, without the need to verify any accuracy in the angular positioning of the cartridge 25, 25 ".

With reference to FIG. 4, the connector 5 may have on its second internal face F2 at least three similar projections, bosses or reliefs R5 projecting inwardly, which make it possible to produce at least three zones of direct radial contact against an external surface. annular S4 of the container 4. This allows a frictional attachment, which may be a removable attachment of the reservoir part R. The cartridge 25, 25 'as a whole can be held in this way integral with the connector 5, 5'. In variants, the second internal face F2 essentially allows centering, a removable connection of the cartridge possibly being possible elsewhere, by peripheral fixing of the stationary part 6a of the dispensing head 6, by coupling / screwing a fixing interface. present on the upper cladding element 8, 108 with a complementary fixing member included in the stationary part 6a.

The R5 reliefs may have a gadroon shape or may be lengthened vertically, typically with a gradual reduction in width as they approach an upper edge RB5 of the connector 5. A number greater than or equal to four spaced R5 reliefs may be preferred. More generally, the second internal face F2 includes any type of projection or protruding contact relief, for example radial contact, separated and distributed over a circumferential annular region of the second internal face F2, in order to center the container 4.

Referring to Figures 2 to 6, the protruding reliefs R5 have a length / height greater than 6 mm to distribute the radial contact over an extended portion of the surface S4 of the container 4. The reliefs R5 shown in Figure 7 define between them a virtual circle CV perpendicular to the longitudinal axis X of the container 4 and which has a center through which passes the longitudinal axis X of the container 4. Although an embodiment is shown with reliefs 5 all provided on a thinned portion N5 of the tubular part 5b and each having the same radial extension projecting inwardly, one can provide a first group of more protruding reliefs formed on this kind of thinned portion N5 and a second group of slightly less protruding reliefs formed in a portion not thinned from part 5b. More generally, different contact zones may be suitable for maintaining the insertion position of the container 4 by spacing it laterally from the inner face facing the body 2.

The container 4 preferably has an annular outer surface S4 of circular section at least in a portion of the surface in contact with the protruding reliefs R5, in the insertion position.

In variants, the container 4 can be placed longitudinally in its insertion position and then, then, clamping portions formed in the connector are actuated, for example by pressure or actuation of activation tabs, before locking the state. of these tongues by covering the connector with the hoop or the like 8, 108 of the upper covering. Such clamping with deformation of the second internal face F2 can also be obtained by a clamping action of the element 8, 108 which comes to bear laterally (from the outside) against the upper portion 5b of the connector.

In a certain variant, the second internal face F2 has an indexing means in rotation with respect to the container 4, so that the cartridge 25, 25 ', internal unit or more generally any part with reservoir R comprising the container 4 is blocked. rotating in a fully inserted state of the container (state in which the container 4 is typically in axial abutment against a stop surface of the body 2 which is perpendicular to the longitudinal axis X, this stop surface possibly being the bottom 2a).

The rotating indexing means can cooperate with a guide relief provided on the outer surface of the container 4, so as to form a foolproof means (possibly with a marking visible at the time of assembly between the internal unit and the connector). This can avoid losing the correlation between the outer body 2 and / or the connector, and the content or type of cartridge to be used. It can also facilitate the detection, if any, of a counterfeit. By way of non-limiting example, the internal face F2 may have ramps on which can slide point reliefs or gadroons (guide reliefs) formed on the container 4, descending to a final locking position. The guide relief can be locked in rotation between two low terminations distributed over a pair of descending ramps which converge towards the reception area (with rotation lock) of this relief. The blocking of the rise of the container 4 may result from a clipping or a clamping contact similar to that shown in Figure 4 but with reliefs R5 typically less extended in height. In the event of clipping, a continuous annular bead or similar external reliefs can be provided on the container 4. When ramps are provided, this type of bead or set of internal reliefs is placed above the ramps and engages beneath. at least one internal gripping rim provided in the upper part of the internal face F2.

In the illustrated case, the container 4 is narrowed by a neck or narrowing / constriction 10c and then widened (via a flange or collar 40) in its coupling zone with a dispensing head 6. However, it is also possible to provide a container 4 which has a constant section at its upper end and, in all cases, the opening O of the container 4 can typically define a diameter of at least 15 or 16 mm, preferably without exceeding 20 or 25 mm when the capacity of the container is less than or equal to 20 or 25 ml_. Such a diameter of the filling opening O may correspond to at least 50% of a minimum internal diameter of the body 2. The dimension of the opening diameter may be greater, within the limit of the diameter of the container 4 (therefore correspond if necessary at 100% of the cross section of the container 4).

Typically, as visible in particular in Figures 1 and 8, the outer body 2 and the connector 5 define a receiving compartment for the container 4 which may be less high than the height H4 of the container 4.

Before mounting the container 4 forming the reservoir part R of the cartridge 25, 25 ', the opening O at the upper axial end 4a of the container 4 has preferably already been closed, in an area axially spaced from one edge upper RB5 of the connector 5, by an assembly or distribution head 6 forming a metering assembly comprising a metering pump 17 and an actuating portion 10; 110 movable to allow the distribution of the product PF contained in the container 4. The cap 16 and the upper element 8, 108 can optionally be provided after the assembly of the container 4 (which can therefore correspond to the assembly of the cartridge 25, 25 ' ). It will be understood that the device 1 constitutes a device for packaging and dispensing the product PF.

Example of disassembling the internal container to extract a cartridge

An example of disassembly of the device 1 will be described with reference to Figures 4, 8, 9 and 10.

FIG. 4 shows a compartment for housing the container 4 which has just been emptied after a decoupling operation. Here the connector 5 snapped and locked in rotation on the neck 2c of the outer body 2 remains held in position, while the cartridge 25 containing the container 4 has been removed, for example by sliding upwards. Although Figure 4 omits to show the upper trim element 8, this can also be maintained as the connector 5, this element can for example be snapped / clipped from below via clip means engaged by the 'outside with the lower edge B5 of the connector 5 (in an area adjacent to the shoulder E2).

This type of dismantling is easy, being facilitated by the presence of thinned portions N5 which increase the plastic deformation in the relief regions R5 distributed here over several angular sectors in part 5b.

FIG. 9 shows another decoupling operation, by a relative rotational movement illustrated by the arrow for rotating an upper connector assembly consisting of the connector 5 ′ and of the upper covering element 8 which has been mounted integral in rotation with the 5 'connector. With the type of connector 5 'used here, a quarter-turn movement is for example sufficient to disengage the skirt 15 or lower part 150 of the connector 5' from the neck 2c, then move the connector 5 'axially to remove it when the lugs internal R1 are no longer placed under the portions or means of Complementary FM1 binding of the RF binding region. Anti-rotation reliefs or at least one indicator may optionally indicate the direction of rotation of the connector 5 ′ allowing disassembly. Any other marking can optionally be used. It is understood that the upper connector assembly grouping together the connector 5 'and the hoop or similar element 8 functionally forms a primary cover, the optional cap 16 constituting a secondary cover which is detachably mounted on the primary cover.

The cartridge 25 'can then be withdrawn by simple axial extraction, out of the body 2. When a cap 16 is provided, the latter can remain fitted or be removed beforehand (which can allow a better grip of the part. tubular element 8 to be rotated).

Of course, after having discarded a cartridge 25 (consumable) already used / consumed, it suffices to insert the reservoir part R of a cartridge 25 'into the body and return the upper connector assembly to the locked fixing position, in reusing the respective connection means. This protects the new cartridge 25 ’which is no longer visible except for the moving part of the device or dispensing head 6.

More generally, whatever the manner of removing the container 4 forming the reservoir part R of the cartridge, reuse of parts, typically of high value, is allowed. With this type of construction, a user can obtain the device 1 including its cartridge 25 and, at the same time, other cartridges 25 'forming compatible refills to be inserted internally between the body 2 and the connector 5 or 5'. . The tightness of all cartridges is obtained identically, so that these 25, 25 "cartridges can be stored for a long time without altering the PF product.

Other connector construction options

The first portion 5a including the first internal face F1 can be presented with a wide variety of reliefs for the axial locking of the connector 5, 5 'on the body 2. The same applies to the second portion 5b making it possible to form the second face. internal F2 in order to block the container 4, this portion 5b surmounting the body 2, typically without reducing / interfering with the passage dimension defined directly by the upper end 200 of the body 2.

With reference to FIGS. 9 and 10, an alternative embodiment is described with a body 2 identical or similar to that of the preceding figures, on which is fixed a connector 5 'provided with an upper covering element 8, so as to protect the sealed container fixing area - dosing assembly.

In this example, the body 2 is a bottle of the carnette type placed at the end 200. The body 2 is made in one piece and includes means for fixing FM1 on a portion of the lateral surface of the neck 2c which is adjacent. to the shoulder E2 of the bottle. The fixing means FM1 have at least one lateral cavity for receiving an internal lug R1 included in the reliefs of the internal face F1. A bayonet connection system can be formed. Here, the cavity or the like of the fixing means FM1 is delimited axially between a portion of the carnette and the shoulder E2, extending circumferentially between a termination zone, or a stop surface having an edge is formed. radially outer, and an access / open conduit with narrowing in section, on the side of an axial access to the peripheral RF attachment region.

The coupling of the connector 5 ′ can be achieved, via axial access zones, by introducing the skirt 15 around the neck 2c, then by exerting a rotation which is preferably of the type representing substantially a quarter turn (more or less minus 10 ° near). The carnette portions, separated by the axial access zones, can be two in number, representing an angular sector between 80 and 105 °, for example of the order of 95 ° (the access zone ZA being able to then represent an angular sector of between 75 and 100 °, for example approximately 85 ° in the non-limiting example of FIGS. 9 and 10).

The bottle or body 2 can be designed with reliefs and a delimitation of lateral cavities, in order to obtain a pre-tightening and then an end-of-travel locking, during the pivoting of the skirt 15.

Referring to Figure 10, the connector 5 'has at least two internal lugs R1, for example diametrically opposed in the internal face F1, which are each of elongated shape in a circumferential direction between a front end, preferably tapered 19f, and a rear end 19r, and each have an intermediate recess 19c, between the front end 19f and the rear end 19r, in order to receive in the locked configuration a projection formed integrally with the bottle / body 2, which is located in the cavity side of the RF attachment region and which provides a notch or abutment surface locking a rotational attachment position.

In practice in the case of this example, the covering element 8 can be rotated relative to the dispensing head 6, which makes it possible to position, here by rotation, the internal lugs R1 of the connector 5 ′ facing areas access ZA (FIG. 9) having an angular delimitation (typically less than or equal to 90 ° or 100 °) and allowing an annular lower end or lower edge B5 of the connector 5 to be placed under the carnette 200 of the body 2. The placement under the carnette 200 of this edge B5 can be carried out at the same time as the engagement in bearing / axial contact of the radial part 5r on the annular upper edge 2r of the body 2.

It will be noted that this embodiment may have similarities with the type of embodiment using a connector 5 which is not moved in rotation during the final locking. Moreover, the connectors 5 and 5 ′ have a similar geometry and comparable functions enabled by reliefs having the same type of arrangement / position in the internal faces F1, F2 of the connector 5, 5 ′. Thus, we note for example that in these two cases, the first internal face F1 is;

- provided in an outer skirt 15 or any type of lower part 5a, 150 analogous to the connector 5; 5 ’, connected to the radial portion 5r of the connector 5; 5 ’; and

- provided with PP pairs of fasteners 12 or 19f, 19r which project inwardly from the first internal face F1, each PP pair having a pair of gripping edges oriented towards one another and delimiting between them a housing 19c in which engages a notch (for example the notch 22 or a similar relief projecting from the fixing means FM1) respectively formed externally on the upper end 200 of the body 2, in order to lock in rotation the connector 5 or 5 'from the body 2.

Of course, the 5 or 5 ′ connector may alternatively have threads for a rotating connection (typically screwing), such threads may be present:

- on the first internal face F1 for fixing the body 2; and or

- on the second internal face F2 for fixing the container 4.

The connector can be produced with different geometries without being particularly limited in its longitudinal profile. In particular, the connector 5, 5 ’can have any type of transition between the parts 5a and 5b, and not necessarily only a radial portion perpendicular to the longitudinal axis X of the container 4.

The device 1 can be compact and is well suited for dispensing the same precise doses of liquid or viscous PF product. Device 1 is typically in the form of a dosing head / dosing tip bottle and designed particularly for cosmetic and other applications requiring a chemically inert material (glass) for contact with the PF product and a high degree of customization. of the outer side wall SW which also includes glass, preferably transparent. Advantageously, use is thus made of the properties of the glass.

In the examples illustrated, it is understood that the container 4 and the dispensing head 6 can form an integral sub-assembly, in the form of a preassembled cartridge 25, 25 ', which can be installed (in one piece). in a glass body 2 with a protective and covering function surmounted by a connector 5 in one piece. Due to the flexible nature and / or plasticity of the internal faces F1, F2 of the connector 5, the user can therefore easily remove the cartridge 25, 25 ', as shown in FIG. 9 by first removing the connector 5 or, more simply, by selectively extracting the cartridge 25, 25 'without modifying the body-connector attachment (the sub-assembly forming the external side wall SW remaining intact), in order to reload the device 1 by using a full cartridge. This makes it possible to reuse the connector 5 and the upper covering element 8, 108 several times, as well as the body 2 made of glass. These reusable parts can then be finely developed and relatively expensive, knowing that it is possible to extend their duration of use beyond the duration of use of the product PF contained in the receptacle 4 of the cartridge 25, 25 '. For the consumer, it can be offered as a choice, either simply to keep these parts including the bottle forming the body 2 while having the possibility of buying only a new cartridge 25 ', or to return the bottle / body 2 to the merchant for , possibly, benefit from a discount or an advantage for a later purchase of another device.

It should be obvious to those skilled in the art that the present invention allows embodiments in many other specific forms without departing from the scope of the invention as claimed.

Thus, although the figures show a container 4 made in one piece, a container with an attached bottom, possibly compatible with a system without venting, can be provided. It is also possible to insert into the body 2 a container 4 with a movable bottom, for example a piston.

Furthermore, the cartridge 25, 25 ’may optionally have a linear guide relief along the body, for example on the second internal face F2 of the connector 5, 5’, and / or any rotational indexing means. For example a pin or orifice for a pin, can be provided in a part of the connector 5, 5 ', here in the second internal face F2 in contact with the container 4 or intermediate insert enveloping the glass container 4 or secured to the head distribution 6.

The recovery of the product PF is allowed by using a pump 17 in the examples illustrated. However, any other method of withdrawing the product PF can be provided, in particular when it is compatible with a sealed conservation of the product PF, by using an element for closing the opening O, a component integral with the cover 16 or any other closure system.
