Description

FIELD OF THE INVENTION The invention relates to a device capable of securing the distribution of a liquid contained in a vial. More particularly, the invention relates to a device comprising a section reducer, integral with the bottle and adapted to receive a syringe for dispensing the liquid. STATE OF THE ART In order to guarantee the safety of persons vis-à-vis liquid products, potentially dangerous for health, contained in bottles, it is necessary that these products are not directly accessible, or at least in less are of limited accessibility. This is even more the case when the persons concerned are young children.

Several types of vials are currently available on the market. The first type that does not meet the desired criteria is the single bottle that, once opened, can transfer the liquid in a spoon, or even drink the liquid directly to the neck of the bottle. This device has the disadvantage of putting the liquid directly within reach of young children. Also known from documents WO 2004/043326 and FR 2,870,827 vials equipped with section reducers, intended to be adapted to the neck of the bottle, and adapted to receive a syringe for dispensing the liquid. However, the section reducer of these devices can be easily removed from the vial, especially once the syringe inserted. This is a second danger for young children, in addition to having the opportunity to ingest the contents of the bottle.

Indeed, the section reducers are often small elements, plastic more or less flexible, which can be easily ingested.

This is the reason why, and for several years, more efficient safety devices have been developed. Among the most often encountered, there are known devices for secure plugs for which it is necessary to exert simultaneous pressure and unscrewing of the plug, to allow the opening of the bottle, as described for example in US 3,857,505, US 5,611,443 , US 7,832,578. According to this principle, the document US Pat. No. 5,484,070 describes a system with double child safety comprising 2 elements, respectively a plug and a section reducer. The removal of the plug is accompanied by simultaneous removal of the section reducer, the liquid contained in the bottle then being accessible. Finally, there is also known document CN 201580664, which describes a closure system comprising a section reducer, and a 2-element plug system. In this device, the removal of the double plug makes the section reducer accessible, which can in turn be detached from the bottle. Thus, the problem is that of developing a system capable of securing the distribution of liquid from a bottle that does not allow: - easy access to the liquid after opening the bottle; and at the same time - access to small elements constituting the security system. SUMMARY OF THE INVENTION The present invention proposes to solve the drawbacks of the state of the art in the field of devices able to secure the liquid distribution by means of a syringe.

Thus, a first aspect of the invention relates to a device adapted to secure the distribution of a liquid contained in a bottle, by means of a syringe, comprising: a section reducer having a first orifice capable of receiving a syringe; an intermediate piece having a second orifice and intended to cap the section reducer, so that said first and second orifices are opposite one another; and a means for closing the first and / or second orifices.

This device is characterized by the fact that: - the section reducer has a screw thread intended to be screwed onto the outside screw thread of the bottle; - The section reducer and the intermediate piece each have: - complementary connecting means, able to bind the section reducer and the intermediate part vertically permanently; - Complementary locking means, adapted to block the rotation of the intermediate piece relative to the section reducer in the screwing direction, and to ensure the free rotation of said intermediate piece relative to the section reducer in the direction of unscrewing. In practice, the connecting means that presents the section reducer is arranged on all or part of the outer wall of the reducer.

In an advantageous embodiment, said connecting means is located near the lower end of the section reducer and is preferably in the form of a first bead.

Advantageously, said connecting means is in the form of a second bead, able to be positioned under the first bead arranged on the section reducer after snapping of the intermediate piece on the section reducer. According to the invention, the section reducer has a locking means in the form of at least one, preferably two diametrically opposed ribs, arranged vertically on the outer wall of said section reducer. In a complementary manner, the intermediate piece has a locking means which is in the form of at least one, advantageously two diametrically opposed strips, arranged vertically on the inner wall of said intermediate piece.

Advantageously, the ribs and lamellae are oriented so as to abut against each other at the time of screwing of the intermediate piece on the section reducer, and to allow free rotation of the intermediate piece relative to the section reducer. moment of unscrewing.

The means for closing the first and / or second orifices can be implemented by several embodiments well known to those skilled in the art. According to a first preferred embodiment, the closure means is in the form of a cap, intended to cap the assembly formed by the section reducer and the intermediate piece. Advantageously, the cover comprises a positioning and locking pin arranged on its inner side wall.

This pin is intended to cooperate with a ramp and / or a net, arranged on the outer side wall of the intermediate piece, and opening into a locking housing.

Advantageously, the bottom of the cover has at least one spring leaf capable of ensuring the positioning of the pin in its locking housing after closing the cover. Advantageously, the bottom of the cover has a shutter, able to sealingly seal the first orifice located on the section reducer. In a second embodiment, the closure means is in the form of a service capsule, a seal being secured to the intermediate piece by means of a hinge.

Advantageously, the lid has a shutter, able to sealingly seal the first orifice located on the section reducer. The invention also relates to an assembly comprising a bottle on which is arranged the device adapted to secure the distribution of the liquid contained in said bottle.

Figure 5 illustrates the device when the 3 elements are associated. EMBODIMENTS OF THE INVENTION As illustrated in FIG. 1, the device comprises: - a section reducer (100), capable of receiving a syringe; an intermediate piece (200) intended to cap the section reducer (100); and a cover (300) intended to close the assembly formed by the section reducer (100) and the intermediate piece (200). As shown in FIG. 2, the section reducer (100) is in the form of a cylinder, of internal diameter greater than the external diameter of the neck of the bottle.

The section reducer (100) is provided with a first port (101) for receiving a syringe.

The section reducer (100) has a locking means in the form of two diametrically opposed ribs (102) arranged vertically on the inner wall of said intermediate piece (200).

The section reducer (100) is provided with a connecting means, in the form of a continuous bead (103), arranged on the lower part of the outer wall. This bead (103) allows the connection of the section reducer (100) and the intermediate piece (200) vertically permanently after snapping of the two elements.

The section reducer (100) also has a screw thread (104) on the inner side wall, to be screwed onto the outside screw thread of the bottle. Finally, the section reducer (100) has a sealing skirt (105) intended to seal the bottle. As illustrated in FIG. 3, the intermediate piece (200) is in the form of a cylinder, of internal diameter greater than the outer diameter of the section reducer (100).

The intermediate piece (200) has a second orifice (201) intended to face the first orifice (101) of the section reducer (100). The second orifice (201) is located in the center of the upper wall (202) of the intermediate piece (200). The first and second ports (101) and (201) do not have the same diameter. The second port (201) on the intermediate piece (200) is larger in diameter than the diameter of the first port (101) on the section reducer (100). The intermediate piece (200) is provided, on its outer face, with a ramp and / or a thread (203), opening into a locking housing (204), thus constituting an end stop screwing, in the screwing direction (Fig. 3A). The intermediate piece (200) further has a locking means, in the form of two diametrically opposed inclined slats (205) arranged vertically on the outer wall of said intermediate piece (200) (Fig. 3B).

The device according to the invention has as many ribs (102), disposed on the outer side wall of the section reducer (100), as slats (205), disposed on the inner side wall of the intermediate piece (200). In addition, the ribs (102) and lamellae (205) may be even or odd. They are positioned to ensure a homogeneous distribution of forces at the moment of rotation of the intermediate piece (200) on the section reducer (100).

Thus, the ribs (102) and the lamellae (205) abut against each other when the intermediate piece (200) is screwed onto the section reducer (100), so that the intermediate piece ( 200) drives the section reducer (100). When the thread (104) of the section reducer (100) reaches the end of the stroke on the screw thread of the bottle, the rotation of the intermediate piece (200) relative to the section reducer (100) is no longer possible in the direction of screwing. On the other hand, the blocking means, constituted by the ribs (102) and lamellae (205), ensure the free rotation of the intermediate piece (200) with respect to the section reducer (100) in the unscrewing direction. Indeed, the angle formed by the ribs (102) and the slats (205) allows the slats (205) to pass the ribs (102) in the direction of unscrewing. This mechanism therefore provides child-type protection, since the intermediate piece (200) can not be detached from the section reducer (100) by a simple rotational movement of the intermediate piece (200) in the direction of unscrewing.

The intermediate piece (200) finally has a connecting means in the form of a discontinuous bead (206). This second bead (206) is positioned under the first bead (103) arranged on the section reducer (100) after snapping of the intermediate piece (200) on the section reducer (100). The intermediate piece (200) then becomes integral with the section reducer (100), which becomes inaccessible. As illustrated in FIG. 4, the hood (300) has a cylindrical shape of inner diameter greater than the outer diameter of the intermediate piece (200).

The hood (300) includes a locating and locking pin (301) disposed on its inner side wall (Fig. 4A). This pin (301), in the form of a net, cooperates with a ramp and / or a thread (203), opening into a locking recess (204), arranged on the outer side wall of the intermediate piece (200). (see Fig. 3).

The bottom of the hood (300) has a series of spring slats (302) which provide positioning of the locating and locking pin (301) in the locking housing (204) after closing (Fig. 4A). The spring strips (302) may be odd or even, but arranged so that the contact points are distributed symmetrically and / or homogeneously on the upper wall (202) of the intermediate piece (200). The bottom of the cover (300) has a shutter (303), able to seal the first orifice (101) (Fig. 4B). Finally, the cover (300) is provided with a tamper-evident tab (304) located in its lower part and intended to be removed from the plug during the first opening of the bottle (FIG 4B). This tamper evident tab (304) is adapted to be torn during the first unscrewing of the cover (300). As illustrated in FIG. 5, the cover (300) covers the assembly formed by the section reducer (100) and the intermediate piece (200).

The slats (302) rest on the upper wall (202) of the intermediate piece (200). The shutter (303) of the cover (300) passes through the second hole (201) located in the center of the upper wall (202) of the intermediate piece (200) and sealingly closes the first orifice (101) located on the section reducer (100).

The bead (206), located near the lower end of the intermediate piece (200) is positioned under the bead (103), located near the lower end of the section reducer (100), thus providing a connection permanent between these two elements after snapping of the intermediate piece (200) on the section reducer (100).

In the closed position, the positioning and locking pin (301) of the cover (300) is housed in the locking housing (204) located on the intermediate piece (200). The spring sipes (302) located in the bottom of the hood (300) hold the positioning and locking peg (301) in its locking housing (204), that is to say in the raised position relative to the end. race of the ramp and / or the net (203). A screwing movement of the cap (300) around the intermediate piece (200) is not possible because the intermediate piece (200) and the section reducer (100) are locked one on the other thanks to the ribs (102) and lamellae (206). On the other hand, a movement in the unscrewing direction allows the free rotation of the cover assembly (300) / intermediate piece (200) around the section reducer (100). When the bottle is intended to be open, for the distribution of the liquid that contains it, the operator must apply pressure on the cover (300). The spring blades (302) deform, so as to allow a vertical translation of the cover (300) towards the bottle. The positioning and locking pin (301) then leaves its locking housing (204). A rotational movement in the unscrewing direction then makes it possible to move the positioning and locking pin (301) in the ramp and / or the thread (203), so as to separate the cover (300) from the intermediate piece (200). ), and thus to move the hood (300) away from the bottle.

Once the cover (300) is disengaged from the intermediate piece (200), the first orifice (101) disposed on the section reducer (100) is then accessible through the second orifice (201), disposed on the intermediate piece (200). ). The syringe can then be disposed in this first port (101) so as to come to take the appropriate amount of liquid contained in the bottle.

When the sampling is completed, the bottle can be closed by the cover (300), in a sequence opposite to that which allowed the opening. Thus, and advantageously, the invention makes it possible to secure the dispensing of the contents of a vial, this being obtained by a device which does not allow: - access to the liquid contained in the vial, once the cap is in an open position, in the case of a liquid potentially dangerous for the manipulator; - Access to the section reducer, itself potentially dangerous, because often small.
