Definitions
- the present invention relates to a fluid dispenser head intended to be associated with, or mounted on, a fluid dispenser member.
- the invention also relates to a method of manufacturing such a dispensing head.
- the dispensing head comprises, within the framework of the present invention, a body defining an outlet channel for the fluid product, a nozzle defining a dispensing orifice and an over-cap mounted on the body so as to mask at least part of it.
- Such a dispensing head can be used in the fields of perfumery, cosmetics or even pharmacy.
- Document FR 2 774367 describes such a dispensing head comprising a body, a nozzle, and an overcap. The body is fixedly attached to the interior of the overcap.
- the over-cap comprises a barrel defining a window at the level of which is positioned the dispensing orifice formed by the nozzle.
- the fluid dispenser head of the invention provides that the overcap is overmolded on the body.
- overmolding is meant that the body forms part of the mold of the overcap.
- the body comprises an upper surface and a peripheral surface
- the overcap is overmolded on the upper surface, and advantageously also on the peripheral surface.
- the over-cap comprises a barrel provided with a window for the passage of the nozzle to be mounted on the body by engaging it through the window.
- the dispensing orifice is positioned in the window.
- the dispensing orifice is positioned set back from the window substantially at the level of an external surface of the body.
- the window has a frustoconical shape which widens outwards.
- the frustoconical surface serves as a diffusion cone which makes it possible to channel the jet of sprayed fluid product through the dispensing orifice.
- the body comprises a peripheral skirt externally forming the peripheral surface, said skirt being provided with an opening giving onto a housing for receiving the nozzle, said housing advantageously forming a core around which the nozzle is committed in force.
- an intermediate element is disposed between the body and the over-cap, said over-cap being made of a material translucent or transparent so that the insert is visible through the overcap. It should be noted that the interposition of this intermediate element between the body and the over-cap can be implemented without the over-cap being molded onto the body. The characteristic linked to the intermediate element can therefore be protected independently.
- the nozzle projects outward from the peripheral surface. Thanks to this overmolding technique, it is possible to produce the overcap while the nozzle is previously mounted on the body. This is not possible with the dispensing head of document FR 2 774 367.
- the dispensing head according to the invention can in particular serve as a pusher.
- the overcap can define a bearing surface intended for the application of pressure to actuate the dispensing member.
- the invention also defines a method of manufacturing a fluid dispenser head intended to be associated with a fluid dispenser member, said head comprising a body defining an outlet channel for the fluid product, a nozzle defining a dispensing orifice and an over-cap mounted on the body so as to mask at least a part of it, said method successively comprising a first step of overmolding the over-cap on the body and a second step of mounting the nozzle on the body.
- the invention may also provide a method for manufacturing a fluid product distribution head intended to be associated with a fluid product distribution member, said head comprising a body defining an outlet channel for the fluid product, a nozzle defining a dispensing orifice and an over-cap mounted on the body so as to mask at least a part of it, the method successively comprising a first step of mounting the nozzle on the body and a second step of overmolding the over-cap on the body , and possibly on the nozzle.
- an intermediate element can be disposed between the body and the over-cap, said over-cap being re-formed in a transparent or translucent material. This applies to both variants of the manufacturing process.
- FIG. 1 is a view in vertical transverse section through a body equipped with a nozzle according to a first embodiment
- FIG. 2 is a view similar to that of FIG.
- FIG. 1 with an overcapsule overmolded on the body of Figure 1
- Figure 3 is a vertical cross-sectional view through a dispensing head according to a second embodiment of the invention
- Figure 4 is a vertical cross-sectional view through a body and a nozzle according to a third embodiment
- Figure 5 is a view similar to that of Figure 4 with an over-molded overmold on the body of Figure 4
- Figure 6 is a vertical cross-sectional view through a body and a nozzle according to a fourth embodiment of the invention
- FIG. 7 is a view similar to that of FIG. 6 with an overmold encapsulated on the body of FIG. 6.
- the he dispensing head comprises three constituent elements, namely a body 1, a nozzle 2 or 2 'and an overcap 3. It is not however excluded that the body and the nozzle are produced in a single piece or in an equivalent manner .
- the body 1 is identical in all the embodiments of the figures. However, other forms can be provided for the body 1. In the case of the figures, it is a body designed to form a dispensing head of the pusher type, which is pressed with a finger. to actuate the dispensing member which can be a pump or a valve.
- actuate the dispensing member which can be a pump or a valve.
- the body is intended to be associated with a distribution member (pump or valve) completely dissociated from the actuator.
- the body 1 is intended to be fixedly mounted relative to the body of the pump or of the valve and to the reservoir.
- the pusher body 1 can be of the standard type reheated in a molded injected plastic which is compatible with the fluid to be dispensed. Ced is explained by the fact that the fluid product comes in contart from the material constituting the body 1.
- the body comprises an upper plate 11 which defines an external upper surface 111.
- the body also comprises a peripheral skirt 12 which defines a peripheral external surface 121.
- the upper surface 111 is connected on its outer peripheral edge advantageously rounded to the substantially or perfectly cylindrical peripheral surface 121.
- the plate 11 and the skirt 12 thus define an inverted cup shape.
- the body internally forms below the plate 111 a connection sleeve 13 and a receiving housing 14.
- the sleeve 13 defines an internal outlet conduit 131 through which the fluid product discharged by the pump or the valve flows into the housing 14 through a small connecting channel 134.
- the housing 14, more visible in FIG. 3, defines an opening 142 at the peripheral skirt 12.
- the housing 14 contains a core 141 formed integrally by the body 1.
- the nucleus externally defines an annular reception for the 2 or 2 'nozzle as will be seen below. This is a completely classic design for a standard pusher body.
- the nozzle 2 or 2 ' according to the embodiments, comprises a base sleeve 20 of substantially cylindrical shape and closed at one of its ends by a distribution wall.
- This distribution wall is traversed by a distribution orifice 21 which may or may not be of the sprayer type.
- a part of the sleeve 20 defines a fixing ring 24 intended to come into engagement in the annular housing formed around the core 141.
- the nozzle can comprise a filling part 23.
- This part 23 can cooperate with the distribution wall so as to form a swirl system, basically made up of radial swirl channels opening into a central vortex centered on the dispensing orifice 21.
- a filling part 23 it is the front surface of the core 141 which cooperates with the dispensing wall to form the vortex system 22.
- the particular design of the nozzle 2 or 2 ' is not critical to the present invention.
- the nozzle it is sufficient for the nozzle to cooperate with the body to fill its spraying foundation with the fluid product.
- the nozzle protrudes outward from the peripheral surface 121 of the body. It could also be said that the dispensing orifice 21 is projected radially outward relative to the peripheral surface 121.
- the dispensing orifice 21 is substantially aligned with the peripheral surface 121. It can also be said that the nozzle is inscribed in the housing formed by the body.
- the dispensing orifice is set back inside the housing formed by the body so that the orifice is offset inwards relative to the peripheral surface 121.
- the nozzle 2 or 2 ′ is mounted by lateral or radial engagement in the housing 14 relative to the axis X shown in FIG. 4.
- the overcap 3 is mounted on the body 1 by coming into contact with a part or of the whole of the upper surface 111 and of the peripheral surface
- the overcapsule may in certain embodiments come in contad of part or all of the upper surface 111, leaving the peripheral surface 121 visible or unmasked.
- the overcap 3 thus masks the major part of the external surface of the body 1, however leaving its lower face open and free so as to be able to mount the dispensing head on a dispensing member such as a pump or a valve. In fact, the connection sleeve 13 must remain accessible.
- the overcap 3 comprises a support wall 31 forming an external support surface 312.
- the overcap 3 includes a substantially cylindrical peripheral barrel 32 which surrounds the skirt 12 of the body 1.
- the support wall 31 comprises an inner surface 311 which comes in contad time with the upper surface 111 of the plate 11.
- the barrel 32 forms an internal surface 321 which advantageously comes into intimate contad with the external peripheral surface 121 of the skirt 12.
- the barrel 32 is also crossed by a window 322 which communicates the outside of the barrel with the inside of the barrel.
- This window 322 is intended for the passage or reception of the nozzle 2 or 2 ′, according to the embodiments, as will be seen below.
- the overcap 3 can also come in close contact with the nozzle 2 at the level of the window 322, as can be seen in FIG. 2.
- the window 322 can be produced with a frustoconical shape 323 which flares outwards.
- the window 322 must be positioned in alignment with the housing 14 of the body 1 intended to receive the nozzle 2 or 2 '.
- the overcap 3 can be reahsée in an aesthetic plastic material which may possibly be incompatible with the fluid product to be dispensed. It can also be re-sheathed in transparent material or in a material offering a contad of silky or rubbery feel.
- the over-cap 3 is molded onto the body 1, and advantageously also onto the nozzle 2. This means that the over-cap 3 is directly molded onto the body and / or the nozzle 2. This technique makes it possible to obtain a contact intimate between the surfaces of the overcap and the body and / or gideur.
- the nozzle 2 is previously engaged radially in its housing 14 formed by the body 1.
- the dispensing orifice 21 of the nozzle protrudes outwardly relative to the skirt 12.
- the over-cap 3 is overmolded on the body 1 as well as on the nozzle 2.
- the overmolding of the over-cap makes it possible to permanently maintain the nozzle 2 on the body 1. This gives a perfectly unitary composite head and cannot be dismantled: it is the overcap which reheats the cohesion of the whole head.
- the dispensing orifice 21 is located in the window 322 which intimately surrounds the nozzle 2. More precisely, the nozzle 21 is located near the external surface of the barrel 32 of the overcap 3.
- the overcap 3 is first molded onto the body 1.
- a pin centered on the housing 14 makes it possible to make the window 322 in the overcap 3.
- a subsequent mounting operation consists in engaging the nozzle 2 through the window 322 until it comes into final mounting in the housing 14 of the body 1.
- the dispensing head is in the form shown in FIG. 2.
- the nozzle 2 ′ is previously mounted on the body 1.
- the orifice distribution 21 does not protrude from the body, but remains aligned with the skirt 12.
- a subsequent molding operation consists of overmolding the overcap 3 on the body 1 with the nozzle 2 'previously mounted.
- a spindle centered on the nozzle 2 ' makes it possible to produce a frustoconical window 322 whose frustoconical wall 323 serves as a diffusion cone for the jet of sprayed product.
- the body 1 and the nozzle 2 ' may be identical to those of Figure 4, that is to say with the nozzle 2' previously mounted on the body 1.
- an intermediate element 4 is arranged on the upper surface 111 of the body 1. This intermediate element 4 can be simply deposited or even fixed on the body 1.
- This intermediate element 4 can fulfill an aesthetic or decorative function. Although the element 4 is shown on the upper surface 111, it can also be imagined that it also or only extends over the peripheral surface 121. A subsequent molding operation consists in overmolding the overcap 3 on the body
- the overcap 3 is made of a transparent or translucent material so as to leave the intermediate element 4 visible through the over-cap 3.
- the over-cap 3 may be identical to that of FIG. 5, that is to say with a frustoconical window 322.
- the interposition of an advantageously aesthetic or decorative intermediate element can be implemented with an added over-cap or fixed in any manner on the body, without it being necessarily necessary for the over-cap 3 to be overmolded on the body 1.
- the overcap 3 is only brought into force on the body 1, like the document of the prior art FR 2 774 367.
- overmolding is an equivalent of the terms “co-molding” or “bi -injection ”. It generally means that an element, in this case the overcap, is molded on another element, namely the body and / or the nozzle. Thanks to this overmolding technique, all tolerance defects are eliminated at the level of the body 1 and of the overcapsule 3. In addition, an assembly operation is eliminated and the fixing of the nozzle 2 on the body 1 is also improved.
