The present invention relates generally to a device for delivering a dose of a determined quantity of a liquid and / or powdery product, such as a flavoring or an additive, and its extemporaneous mixture with a basic product contained in a container, prior to distribution.

State of the art

It is well known that many products include additives, such as flavors or perfumes or active ingredients, intended to improve the organoleptic properties of said products or to activate pharmaceutical or cosmetic active ingredients. These additives, once mixed with the product, which can be altered over time due to instability of the mixture, incompatibility with the base product, oxidation with one of the constituents of the base product, etc., it is known. to introduce the said additive (s) into the basic product just before the use of the said product.

To this end, devices known as dose distributors have been devised making it possible to introduce a predetermined dose of the additive (s) into a basic product. This is particularly the case for documents EP 1 819 603 and EP 2 990 350.

Document EP 1 819 603 describes a closure capsule, the cap of which comprises a receptacle formed inside the cover and fitting inside a corresponding stud part. An associated film-sealed container capsule can be locked inside the receptacle, with the film facing down, so that the sealing film is against the inner diameter of the cap. An inwardly projecting circular shoulder is configured inside the nipple portion below the inserted container capsule. Several fixed and / or movable drilling and / or cutting elements are formed on the internal edge of said shoulder. A tamper-evident band is supported on a shoulder which projects radially outward below the bottom edge of the capsule. Once said strip has been removed, the cap can be pushed down on the nipple part,

PAT2529483FR00 causing the film to open by the drilling and / or cutting elements. The section of the nipple part located under the shoulder can be configured as a collar or a flange.

The document EP 2 990 350 describes a dispensing and mixing device designed to be fixed on an opening of a receiving container and intended to receive a self-contained container having an opening closed by a closure film and containing an additive product to be dispensed in the interior space of the receiving container containing a different product. Said device comprises a holding element capable of receiving and retaining the autonomous container in the region of its opening, an assembly element intended to be fixed on the opening of the receiving container and to receive said holding element by screwing, element comprising a generally smooth and open passage part which can engage in a homologous part of said holding element, said passage part forming a pouring spout and incorporating an element for opening the closure film of the autonomous container by putting in place a resistance to the closure film in a peripheral region of the latter to tear and open laterally said closure film during the screwing of the retaining element on the assembly element, the assembly element and the retention element assembled , forming an interior volume which forms a generally closed and generally smooth and open passage between the interior space the receiving container and the interior space of the self-contained container after opening the closure film.

All of these devices, apart from the fact that they are complex and expensive to manufacture, have the drawback of being bulky so that their use on known bottles is not ergonomic and not very compatible with consumer expectations. In addition, these devices do not allow the introduction of an additive into a carbonated liquid such as beer or lemonade or sparkling water.

Embodiment of the invention

PAT2529483FR00

For the sake of clarity, in the following description, the same elements have been designated by the same references in the different figures. In addition, the various views are not necessarily drawn to scale.

The following will be described as a removable device for dispensing a dose of an aroma in a beer contained in a bottle comprising a threaded tube, in order to allow a consumer to flavor a beer as he wishes; however, it is obvious that said device according to the invention can be used for any type of drink, such as lemonade, or still or sparkling water for example, or for any other type of liquid contained in a container. without departing from the scope of the invention.

With reference to FIGS. 1 to 5, the removable device 1 according to the invention for dispensing a controlled dose of a liquid and / or pulverulent product within a liquid or a solid contained in a container 2, comprises a reservoir 3 (FIG. 3) containing the controlled dose of a liquid and / or pulverulent product and closed by a cover 4 or similar and a cap 5 capable of being secured to a threaded tube 6 of the container 2. Said cap 5 is consisting of a so-called lower part 5a on the one hand and a so-called upper part 5b on the other hand. The lower part 5a comprises an internal thread 7 capable of cooperating with the external thread 8 of the threaded tube 6 of the container 2, a central opening 9 opening into the container 2, capable of receiving the reservoir 3, as will be detailed below, and comprising means for tearing 10 of the cover 4 of said tank 3 and means for guiding in rotation and / or translation 11 of said tank 3, and an external thread 12. The upper part 5b comprises an internal thread 13 able to cooperate with the external thread 12 of the lower part 5a and closing means 14 of the central opening 9 of the lower part 5a.

In this schematic embodiment of the device according to the invention, the container 2 is in the form of a bottle; however, it is obvious that said container 2 may be in the form of a jar, a gourd, a flask or the like containing a liquid or a solid without departing from the scope of the invention.

PAT2529483FR00

The container 2 according to the invention may be made of plastic, of PET better known under the name of polyethylene terephthalate, of glass or any other material known to those skilled in the art which may contain a liquid or a solid, it may also contain gels or colloids.

Said container 2 therefore comprises in its upper part a threaded pipe 6 able to cooperate with said plug 5, the external threading of the pipe 6 advantageously comprising so-called degassing grooves, not shown in the figures, also called vents facilitating the evacuation of gas in the case where the liquid is a carbonated drink or beer, when said container 3 is handled, or when a dose or more controlled doses of liquid and / or powder from the reservoir 3 are added. This makes it possible to prevent the liquid contained in the container 2 from overflowing on the one hand and to degas gradually to reduce the pressure in the bottle and thus avoid a dangerous projection of the stopper 5.

Referring to Figure 4, said internal thread 7 of the lower part 5a comprises first degassing grooves 7a; the external thread 12 of the lower part 5a comprises second degassing grooves 12a and the internal thread 13 of the upper part 5b comprises third degassing grooves 13 a.

The liquid contained in the container 2 according to the invention can be still or sparkling water, an alcoholic drink such as whiskey, vodka, wine or preferably a carbonated alcoholic drink such as beer. The liquid can be a non-alcoholic drink such as juice (grapes, apples, orange, etc.) or drugs or perfumes in liquid form or gels. The solid contained in the container 2 according to the invention may also be a powder used as a medicament or as a food, milk for example. In the case of gels, mention may be made of food gels or of drugs in the form of a gel.

The controlled dose contained in the reservoir 3 is preferably in the form of a liquid and / or a powder. It can correspond to one or more flavor (s) as soon as it is a question of imparting new organoleptic properties to a liquid, solid or gel or to a colloid contained in container 2. It can also correspond to a drug or

PAT2529483FR00 a chemical compound other than a flavoring capable of modifying the physicochemical properties of a liquid or a solid present in said container 2.

Referring to Figure 3, the controlled dose is contained in the reservoir 3 in one, two or more separate compartments, each compartment (s) being able to contain an equivalent or different liquid and / or powdery product. This has the advantage of being able to precisely control the dose of liquid and / or powder to be added to the container 2. This is particularly true in the case of flavorings, since they are often unstable or very reactive from a physical point of view. -chemical.

Maintaining them in a tank 3 at a precise dosage in one or more compartment (s), makes it possible to be able to add them to the container 2 in an efficient, precise manner while preserving their physicochemical properties and confer on the liquid or solid. of container 2 new organoleptic properties, and according to the wishes of the consumer in the case where the liquid is beer for example.

The fact of separating the reservoir 3 into several compartments, may prove to be particularly useful when liquids and / or pulverulent are not chemically compatible in a single composition, but are when they are integrated into the liquid or the solid contained in the container 2. This separation in different compartments also allows, if the compartments contain the same liquids and / or powders, to be able according to the tastes of the user to gradually reinforce the organoleptic properties of the liquid or the solid contained in the container 2 .

The compartment (s) containing the controlled dose (s) is / are protected from the external environment by a cover 4 closing the base of the reservoir 3. Thus, in order to release the controlled dose (s), it suffices to pierce or to tear the cover 4 extending at the base of the reservoir 3.

It will be understood that the removable device 1 according to the invention makes it possible to deliver a dose or several controlled doses of liquid and / or of a pulverulent product contained in the reservoir 3, while avoiding that this addition is compromised by a reaction

PAT2529483FR00 secondary between the liquid or the solid present in the container 2 and the dose (s) of liquid (s) and / or powder (s) present (s) in the reservoir 3.

The seal 4 which is used to maintain the dose or doses to be delivered within the reservoir 3 can be in the form of a thick or thin layer, metallic like aluminum, or obtained in polymers or fibers. It will be observed that the cover 4 can be obtained in one piece with the body of the reservoir 3, in the same material as the latter, so that there is no seal between the cover 4 and the tank body. The seal 4 will be chosen as a function of its chemical neutrality with respect to the controlled dose (s) of liquid (s) and / or powder (s) present in the reservoir 3. The seal 4 may have a smooth or pre-functionalized surface in the context of the present invention. Pre-functionalized is understood to mean a treatment of the surface of the cover 4 by embossing techniques or even pre-cuts making it possible to facilitate tearing thereof, and thus making it possible to deliver the controlled dose (s) more effectively. of liquid and / or powder contained in the tank 3.

In this particular embodiment, the reservoir 3 comprises a main body 3a of conical shape and a base 3b of cylindrical shape, the base 3b having an outside diameter just less than the inside diameter of the central opening 9 of the plug. However, it is obvious that the reservoir 3 may have any shape and be obtained in a rigid, semi-rigid or flexible material without departing from the scope of the invention. The base 3b of the tank 3 comprises slots 15 made in the side wall of the tank 3 and able to cooperate with the guide means 11 which are in the form of diametrically opposite lugs extending in the central opening

9. These slots 15 have an L shape, one of the branches of L opening at the lower end of the reservoir 3, in order to provide guidance in vertical translation and guidance in rotation of said reservoir 3.

The advantage of such a configuration is to allow the reservoir 3 to be fixed temporarily but stable on the lower part 5a of the plug and to ensure the hermeticity of the device when the reservoir 3 and the part 5a cooperate.

PAT2529483FR00

According to an alternative embodiment, not shown in the figures, the distal end of each slot 15 has a recess in which is housed the corresponding lug 11 in order to definitively block the reservoir 3 in the central opening 9.

The lower part 5a comprises a cylindrical shell which has an upper circular plate 20, also called the bottom wall, and a cylindrical skirt 21 and which is made of a plastic material having good rigidity properties such as polyethylene or polypropylene for example . The lower end of the cylindrical skirt 21 is extended by an annular flange 22 and may advantageously include a tamper-evident ring secured to the lower part by bridges of breakable material, not shown in the figures.

Said tamper-evident ring may be composed of at least two circular fragments separated by at least one longitudinal slot and each linked to the lower part, on the one hand, by a non-breakable trigger guard and, on the other hand, by trigger clips breakable arranged to cause the beginning of rupture in the middle of the interval separating the non-breakable trigger guard from the end of the same fragment which is juxtaposed with the slit. Furthermore, the cylindrical skirt 21 includes an internal thread 7 able to cooperate with the external thread of the threaded tubing of a container, as well as an external thread 12. By way of example, the lower part 5a of the plug is dimensioned so that the internal thread 7 is able to cooperate with the thread of the tubing of a bottle with a standardized diameter 28 according to the standards commonly used. These provisions can also be used for different diameters, such as for example diameters of 32 38 40 or others, depending on the type of container.

Furthermore, the circular plate 20 of the lower part 5a comprises a circular central opening 9, opening into the container when the lower part is screwed onto the tubing of a container, and capable of receiving the reservoir 3.

These blades 24 are obtained in the same material as the rest of the lower part 5a of the stopper, i.e. in polyethylene or polypropylene for example, during the molding of the latter. The central opening 9 is suitable for receiving a reservoir 3, shown in FIG. 8, containing a controlled dose of a liquid and / or pulverulent product and comprising a lower part closed by a cover which is pierced when the reservoir is positioned in the central opening 9 and which is torn when the tank is rotated inside said central opening 9. Said tank 3 has a cylindrical shape whose lower end is closed by a cover 4, the inside diameter of the tank 3 being just greater than the outside diameter of the cylindrical sleeve 23. In order to keep the reservoir 3 in position on the lower part 5a of the stopper 5, and to prevent its removal from the stopper 5, said reservoir 3 comprises an annular lip called inner 25, extending inside the reservoir 3 at its lower end, just above the cover 4, capable of cooperating with with a complementary annular lip 26 integral with the cylindrical sleeve 23.

Referring to Figures 6 and 10, the upper part 5b comprises a cylindrical shell which has an upper circular plate 27, also called the bottom wall, and a cylindrical skirt 28 and which is made of a plastic material having good stiffness properties such than polyethylene or polypropylene for example. Said cylindrical skirt 28 of the upper part 5b comprises an internal thread 13 able to cooperate with the external thread 12 of the lower part 5 a and the internal wall of the plate 27 forms means for closing the central opening 9 of the lower part 5a by bearing on the upper edge of the cylindrical sleeve 23.

Referring to Figure 4, said internal thread 7 of the lower part 5a comprises first degassing grooves 7a; the external thread 12 of the lower part 5a comprises second degassing grooves 12a and the internal thread 13 of the upper part 5b comprises third degassing grooves 13 a.
