Definitions

• the closure member provides a storage place for the container. It is a receptacle for the container.
• the closure member limits the course of the compressible zone.
• the closure member can cover totally or partially the compressible zone. It can for example be cut out in order to leave a space for an easier actuation of the compressible zone by the finger. In the case, the closure member can be cut out to provide a concave space for the position of the finger. In this case also, the "compressible chamber is entirely housed inside the closure member". Compressible zone
• the thickness of the bellows is for example between 0.1 mm and 1 mm, and preferably between 0.3 mm and 0.8 mm.
• the number of folds in the bellows may be between two and six, better still between three and five.
• the closure member is substantially in the form of a hollow cylinder that is open at its two axial ends.
• the compressible zone and the closure member can be firmly attached to one another by snap-fastening, force-fitting or clip-fastening or screwing.
• the closure member delimits a deformation of the compressible chamber between two end positions which define the travel of the compressible chamber.
• the closure member advantageously has a limit surface that forms a stop.
• the compressible zone may be entirely compressed by the user during the expulsion of the product.
• the device according to the invention is such that the compressible chamber is partially relaxed in the completely closed position of the closure member on the container.
• the return to the closed position, and thus the return of the compressible chamber into a retracted position allows at least a part of the product contained in the pipette to be ejected back into the container.
• the majority of the product that remains to be dispensed is stored in the container, outside the pipette.
• the closure member comprises a thread for engaging with a complementary thread on the container.
• the rotation of the closure member in relation to the container brings about the relaxation or compression of the compressible chamber, for example the elongation of the bellows along the axis X or the shortening thereof.
• the closure member may comprise a threaded ring. It may also have a thread on its inner wall.
• the closure member may comprise bars for guiding the movement of the compressible chamber. It is for example a ramp for longitudinal guidance so as to allow the compression of the compressible chamber.
• the device according to the invention advantageously comprises a means for wiping the pipette, said wiping means being mounted on the container.
• the wiping means is effective especially in the case of a pasty formulation.
• FIG. 1 a longitudinal section through a device according to the invention in a closed position
• FIG. 2 a longitudinal section through a device according to the invention in an unscrewed position of the closure member from the container;
• FIGS 4, 5 and 6 show suction phases of the pipette:
• FIG. 4 a perspective view of a device according to the invention in a closed position
• FIG. 5 a perspective view of a device according to the invention with the closure member partially unscrewed;
• FIG. 6 a perspective view of a device according to the invention with the closure member completely unscrewed
• FIG. 7 a perspective view of another device according to the invention in a closed position
• FIG. 8 a perspective view of another device according to the invention with the closure member partially unscrewed;
• FIG. 9 a perspective view of another device according to the invention with the closure member completely unscrewed.
• Figure 1 shows a device for packaging and dispensing a product.
• the closure member 1 is entirely screwed onto the container 4.
• the product contained is preferably a cosmetic product such as a care cream, a day cream, an antiwrinkle cream or an anti-aging serum.
• the product is generally in the form of a fluid, preferably a liquid.
• the device comprises a container 4 for containing and storing the product before it is sold and then during its useful life with a user.
• the container is closed off by a closure member 1.
• the closure member 1 accommodates a compressible chamber 2.
• the latter comprises a bellows 22.
• the compressible chamber 2 is in the retracted position in figure 1. It does not protrude axially, along a longitudinal axis X, in relation to the closure member 3. This chamber 2 is completely hidden in the closure member 3 when the device is viewed from the front. It is invisible to an observer looking at the front of the device.
• the movement of the bellows 22 can be surrounded by cylinder portions.
• the latter are located on the inner face of the closure member 1.
• the stiffness of the closure member 1 is also reinforced. These cylinder portions should resist the excess pressures which are exerted upon each actuation of the bellows 22.
• the pieces are arranged so as to limit friction between the plate 29 and the cylinder portions surrounding the movement of the bellows.
• a coupling may be provided between the plate 29 and the top of the bottle neck so as to ensure the extension of the bellows before the movement of the plate, during opening.
• the closure member 1 is provided locally on its inner periphery with a thread 16 that is intended to engage with a complementary thread 17 provided on the outer periphery of the container.
• the container 4 has a neck 18 having a cross section smaller than the section of the housing formed in this container for containing the product.
• the thread 17 is formed around this neck 18.
• the pipette 3 may be produced in two pieces. It may also be held by snap-fastening in a plate 29 located at the end of the bellows 22. It is produced for example from glass.
• the container 4 is also produced for example from glass, or from a thermoplastic material. It may, for example, be obtained by an extrusion blow molding technique. It may also be obtained by joining together a number of components. It has, for example, a circular or ovoid cross section.
• the container 4 may be topped by a cover band in order to ensure the appearance and overall design of the device. This cover band may be produced from a different material in order to a create a material or color contrast with at least one of the container 4 and the closure member 1.
• the base 33 of the pipette 3 rests against a shoulder of an insert by way of a sealing lip so as to ensure a good level of sealing.
• Figure 2 shows the device after the closure member 1 has been completely unscrewed.
• the compressible chamber 2 has extended along the axis X. In this intermediate position in accordance with the invention, the compressible chamber does not protrude from the top of the closure member 1.
• the travel of the bellows 22 is at a maximum. It is limited by the stop 7.
• the product has risen inside the pipette 3 in order to fill the depression associated with the increase in volume of the bellows 22.
• the bellows 22 extends but the pipette 3 remains in a fixed position.
• the base 33 of the pipette is placed directly in an active position, without compensating for play during the compression of the bellows 22.
• a user pushes with his forefinger against the compressible chamber 2 so as to compress the latter.
• the compression causes the product to be expelled from the pipette 3 into the container 4.
• the product can be forced out of the pipette 3 in order to be deposited on the user's skin, his hair, his nails or any other surface.
• Figures 4 to 6 show the filling of the pipette depending on the degree of unscrewing of the closure member 1.
• the closure member 1 is half screwed onto the container 4.
• the pipette 3 is half filled.
• the filling level of the pipette is hi.
• the closure member 1 has been completely unscrewed from the container 4. It is simply resting on the neck 18.
• the pipette 3 has been filled.
• the filling level of the pipette is h 2 , representing the filling level permitted at the end of opening by unscrewing.
• the product is ready to be applied to a surface. For example, it is deposited, after the closure member 1 has been moved, on a selected surface to be treated.
• Figures 4 to 6 show a further compressible chamber 2 entirely housed inside the closure member 1.
• the present invention has been described with reference to particular embodiments that are illustrated in figures 1 to 6, but it will be understood that other variants can be envisaged by a person skilled in the art.
• the shape of the container and/or of the compressible part and/or of the closure member may be modified while keeping the compressible chamber 2 entirely housed inside the closure member 1.
