Claims

1. A device comprising: a bottle having two open ends, the bottle comprising a central body receiving a first product, one end with an opening receiving a stopper, said stopper having a central part in the form of a jar which is engaged in said opening and which delimits a cavity which initially contains a second product to be mixed with the first product and another end opposite the one end with an opening receiving a removable cap and provided for withdrawing the mixture after removal of the cap, said stopper carrying a part which can be moved axially and capable, when pressed down, of opening a closed bottom of the cavity to release the second product, said part engaging, via a projecting central part, into the cavity, the bottle further including an outer thread adjacent the end receiving the stopper and the stopper further including an outer skirt with an inner thread, wherein the inner thread cooperates with the outer thread.

2. The device according to claim 1, wherein the stopper is equipped with a tamperproof tab whose presence holds said projecting central part of the part distant from the closed bottom of the cavity, and whose removal allows the part to be pressed down with a view to opening the closed bottom of the cavity to release the second product.

3. The device according to claim 1, wherein the other end of the bottle, receiving the cap also carries, or itself forms, a section reducer with a central orifice having a diameter corresponding to the diameter of a dosing syringe which can be used to withdraw the mixture.

4. The device according to claim 1, further configured for an extemporaneous preparation of liquid medicinal products, or for preparation of food supplements.

[0023] FIGS. 4 to 8 are schematic illustrations of the device in the preceding figures.

DETAILED DESCRIPTION

[0024] The device shown in the drawing and globally denoted 1 chiefly comprises a bottle 2 open at its two ends, a stopper 3 placed at one end of the bottle 2, and a cap 4 mounted on the other end of this bottle 2.

[0025] The bottle 2 has a central body 5, preferably made in a transparent material. At one end, the bottle 2 has a first circular opening 6. This end can be provided with a thread 7 (if the stopper 3 is a screw-on stopper). At its other end, also open, the bottle 2 can be provided with an outer thread 8 (if the cap is a screw-on cap).

[0026] With more particular reference to FIGS. 2 and 3, the stopper 3 has an outer skirt 9 provided with an inner thread 7 cooperating with the outer thread 7 of the bottle 2. The stopper 3 also has a central part 10 in the form of a jar which is engaged in the circular opening 6 of the bottle and which delimits a cavity 11.

[0027] A part 12 of general cylindrical appearance caps the stopper 3 and also engages, via its projecting central part 13, into the cavity 11 delimited by the central part 10 of said stopper 3. A ring-shaped seal 14 is inserted between the top of the stopper 3 and the central part 13 of part 12.

[0028] A tamperproof tab 15 is provided at the base of part 12, around the lower region of the outer skirt 9 of the stopper 3. The initial presence of the tamperproof tab 15 holds the central part 13 of part 12 distant from the bottom 16 of the cavity 11.

[0029] This cavity 11 is provided to receive one of the two products (liquid or solid) to be mixed, whilst the central body 5 of the bottle 2 is provided to receive the other product (liquid or solid). As will be understood, the two products remain well separated from one another for as long as the closed bottom 16 of the cavity 11 remains in place.

[0030] At its other end, in the illustrated example, the bottle 2 receives a section reducer 17, added and welded, that delimits a central orifice 18 of circular shape. The diameter of the central orifice 18 corresponds to the diameter of a dosing syringe 19, known per se. The cap 4 initially caps the reducer 17 on which it is mounted (thread 8).

[0031] At the time of use, the tamperproof tab 15 is torn off (FIG. 4) and part 12 which is released axially over a certain distance is pressed down (FIG. 5) so as to open the closed bottom 16 of the cavity 11. The product initially contained in this cavity 11 then falls into the central body 5 of the bottle 2 where it mixes with the product already contained in said central body 5. The mixture of the two products is made homogeneous by shaking the device.

[0032] The device is then upturned and the cap 4 is removed, as shown FIG. 6. The dosing syringe 19 is next inserted in the orifice 18 and used to withdraw a determined quantity of the formed extemporaneous preparation (FIG. 7). After dosing, the syringe 19 is withdrawn (FIG. 8) and used to administer the medicinal product. Finally, the cap 4 is put back in place, at least if the device is not empty.

[0033] The device described above is particularly well suited for extemporaneous preparations of liquid medicinal products made from two liquid products or from a solid and a liquid, the term <<liquid>> designating aqueous products as well as oil products or gels. These may be preparations for oral or intravenous use. This device can also be used to prepare food supplements, or for any other similar preparations which require the separate storage of two products of which at least one is liquid, followed by the mixing of these products and dispensing of the formed mixture with or without precise dosing. Therefore the use comprising a dosing syringe and a section reducer adapted for said syringe is in no way compulsory, and it can just as well be envisaged that the second end of the bottle does not contain a section reducer and receives a teat or is directly brought to the mouth for drinking or swallowing the content, any form of withdrawal of this content possibly being envisaged.

[0034] The invention, as follows from the foregoing, is evidently not limited to the sole embodiment of this device for packaging two products to be mixed and for dispensing the mixture of these products, as described above by way of example; on the contrary it encompasses all variants of embodiment and application which follow the same principle. Therefore, it would notably lie within the scope of the invention if modifications were made to details of shapes and to the assemblies of the components of the device, for example by modifying the volume of the bottle, by replacing the screw-on cap by a press-fit cap or by arrangements such as adding or eliminating seals between these components or through the use of accessories or additional accessories intended to facilitate the use of the device; it can therefore be envisaged for example to adapt onto the stopper or the bottle itself an <<intelligent label>> which forms a type of visual alarm allowing measurement of the time elapsed since the contacting of the two liquids or of the liquid with the solid.
