Definitions

• the present invention relates to a dispensing head intended to be mounted on a fluid dispenser, and in particular a head comprising a cover for selectively closing and clearing a dispensing orifice, and also relates to a dispenser provided with such a head.
• the installation of a cover on a dispensing head generally fulfills several objectives. The first is to avoid any clogging of the dispensing orifice, between two actuations.
• the hood can also prevent leakage of fluid.
• the cover can also prevent the fluid product contained in the tank from being permanently in contact with the outside ambient air which can be the source of microbiological contamination of the product to be delivered and / or a modification of the chemical composition of said product. product.
• the covers listed in the prior art thus have the objective of selectively masking and unmasking a dispensing orifice through which the product contained in a reservoir can escape following an actuation by a user.
• the purpose of these covers is thus to cover the dispensing orifice when the user is not using the dispenser and to discover it by removing said cover when the user wishes to dispense a dose of fluid product.
• the removal of the cover is then normally implemented by an axial traction exerted on the cover by the user in order to completely separate said cover from the dispensing head.
• accidental withdrawals are likely to take place, for example during the transport of a dispenser in a bag, which can then be the source of leaks of liquids in the bag.
• the object of the present invention is to overcome the abovementioned drawbacks of the prior art and to define a dispensing head which is both simple to manufacture and to assemble and of low cost price.
• the present invention therefore aims to provide a dispensing head which in particular limits the risks of fouling of the dispensing orifice, leakage of fluid and contamination of the fluid between two actuations.
• Another object of the present invention is to provide such an easily maneuverable head which can possibly be manipulated with one hand.
• the present invention therefore provides a dispensing head intended to be mounted on a fluid dispenser, said dispensing head comprising a body provided with a dispensing orifice, said head being provided with a cover movable between a closed position, in which it covers said dispensing orifice, and an open position, in which it does not cover said dispensing orifice, said cover being permanently and in all positions connected to said body.
• said cover is connected to said body by a bridge of material.
• said material bridge forms a hinge around which said cover pivots between its two positions.
• said material bridge is provided on or near the periphery of a radial flange forming the actuation surface of said head.
• a dispensing head comprising a cover, the tilting of which in the open position will not cause any discomfort for the user when the latter wishes to compress the actuating surface to expel a dose of fluid, the cover shifting completely relative to the actuating surface.
• said cover in the closed position, before the first use of the dispenser, comprises a safety and / or first use indicator.
• said safety and / or indicator of first use is achieved by a part of the cover intended to be broken, torn off or separated. of said cover during the first use, when the cover is moved the first time out of its closed position.
• said safety and / or first-use indicator comprises a projection connected to said cover and cooperating with the peripheral edge of said radial flange, said projection having to be broken, torn off or separated to allow said cover to pass from the initial closed position to the open position.
• said cover comprises at least one lateral opening. This characteristic notably facilitates the pivoting of the cover relative to the body between its two positions, in particular in the case of a nasal dispensing head.
• said dispensing orifice is provided on an axial extension of said body, said axial extension passing through said opening when the cover is moved between its two closed and open positions.
• said opening promotes drying of the product at the dispensing orifice when the cover is in the closed position.
• said cover comprises an external trigger facilitating the handling of the cover.
• said trigger is located in the extension of said opening. This facilitates actuation of the cover.
• said head is a nasal delivery head intended to be inserted into a nostril.
• FIG. 1 is a schematic cross-sectional view of a dispensing head provided with a cover according to an embodiment of the present invention in the initial closed position
• FIG. 1 is a schematic cross-sectional view of a dispensing head provided with a cover according to an embodiment of the present invention in the initial closed position
• FIG. 2 is a view similar to that of the FIG. 1, in the semi-open position
• FIG. 3 is a view similar to that of FIGS. 1 and 2, in the open position
• FIG. 4 is a partial view of the detail A of FIG. 1.
• the head comprises a body 1 provided with a dispensing orifice 10, and this fluid dispensing head is generally intended to be mounted on a dispensing member able to extract the fluid contained in a reservoir.
• the dispensing member may for example be a pump or a valve fixed to a reservoir.
• a protective cover 2 is associated with said head, said cover being movable between a closed position (figure
• the body 1 comprises an axial extension 13 of substantially cylindrical or conical configuration provided with the dispensing orifice 10 at its end.
• the dispensing orifice 10 could also be located laterally, for example for oral use.
• the axial extension 13 advantageously internally defines a duct capable of causing the dispensing orifice to communicate with the dispensing member (not shown).
• the axial extension 13 is advantageously extended by a part which widens outwards and can form a substantially radial flange 12.
• the axial extension 13 or the radial flange 12 can form an actuating surface on which a user exerts a force to trigger the dispensing of a dose of fluid product.
• a skirt 14 of advantageously cylindrical shape extends downwards from said radial flange 12. This skirt advantageously extends around the neck of the tank (not shown) with its lower end which can abut against the tank in order to define a stop to the axial translational movement of the dispensing head during an actuation.
• the cover 2 advantageously has a general shape of a bell.
• the cover 2 has a top 23 from which extend side walls 24, the lower end of which forms an annular ring 25 capable of coming to bear against the radial flange 12 of said body 1.
• This annular ring 25 can cooperate by friction with the outer edge of the flange 12 to maintain the cover in the closed position and force the user to overcome this friction to open it.
• the permanent connection of the cover with the head is formed by a material bridge 11 which permanently connects the cover 2 to said body 1.
• the material bridge 11 preferably constitutes a hinge around which the said cover pivots to selectively cover or uncover the dispensing orifice 10 thus respectively defining the closed position and the open position.
• the hinge 11 is advantageously located at the edge of the actuation surface, preferably at the peripheral edge 120 of the flange radial 12.
• the arrangement of the hinge 11 at the periphery of the flange 12 thus makes it possible to move the cover 2 relative to said body 1 so that said cover 2 goes to be placed in the open position opposite the skirt 14 as seen on Figure 3.
• This particularly advantageous arrangement of the hinge 11 thus ensures a location of the cover 2 in the open position which will in no case disturb the accessibility to the radial flange 12 intended to be compressed to deliver a dose of fluid product.
• the material bridge 11 can be made in such a way that it resiliently biases the cover in the closed position, the user having to overcome this elastic force to open the cover.
• a trigger 22 is advantageously provided on said cover in order to facilitate its handling, that is to say the passage of the cover from one position to another.
• This trigger 22 advantageously forms a protruding puff that the user can easily grasp to move said cover 2. This displacement can even be implemented with one hand, the thumb of the user being able, for example, to press on said trigger to then tilt the cover to the open position. More generally, the opening of the cover and the actuation of the dispenser can be carried out with one hand.
• the cover 2 comprises at least one lateral opening 121. The trigger 22 advantageously overlooks this lateral opening 21.
• the lateral opening 21 can have any shape: round, ovoid, elliptical, ellipsoidal, rectangular, square, etc. It is preferably of sufficient size so that the axial extension 13 cannot hinder or block the tilting of the cover 2 around said hinge 11.
• the lateral opening 21 also has the advantage of ventilating the interior of the cover 2 in the closed position and can thus promote drying of the product capable of remaining close to the dispensing orifice 10 as a result fluid product distribution.
• the presence of this opening 121 in the hood makes it possible to produce a hood whose dimensions are close to those of the head, even when it is a nasal head whose axial extension 13 can be significant, while being captive, and in particular pivotally mounted on said head.
• the cover 2 advantageously includes a security and / or a first-use indicator 20.
• This security and / or this first-use indicator 20 constitutes a tamper-proof device proving that the cover 2 has indeed remained in the closed position until the first use by the user and therefore that no dose of fluid has been dispensed beforehand. This guarantees the dosage of the product contained in the tank and its sterility.
• This security and / or this first-use indicator is advantageously secured to said cover, at the level of the annular ring 25, and may include a projection 200 capable of coming to bear against the peripheral edge 120 of the radial flange 12. This projection 200 advantageously accommodates under the peripheral edge 120 in order to prohibit any tilting of the cover outside of its closed position.
• the cover 2 can then freely move from the closed position masking the dispensing orifice 10 to an open position unmasking said orifice 10 by rotation around said hinge 11.
• the cover can also include anti-actuation means which, in position closed cover, preventing the actuation of the dispensing member (for example a pump) and which, in the open position of the cover, allow this actuation.
• the cover could include an extension or projection adapted to cooperate in the closed position with a part of the reservoir or an element integral with the latter, to form a mechanical stop preventing actuation.
• the embodiment as presented of the dispensing head implements a cover permanently secured in all positions to a body in order to make it inseparable from said body and therefore captive. Furthermore, this cover makes it possible to simply produce a first-use witness system. It should be noted that various modifications can be made to this invention by those skilled in the art without departing from the scope of the invention as defined in the appended claims.
