Definitions
- the present invention relates to a dispensing and application head intended to be associated with a dispensing unit, such as a pump, a valve, a flexible tube, etc.
- the head includes a connection stub for connection to the dispensing unit, a mounting core connected to the connecting stub, and a fluid application pad for contacting a target surface, such as the skin, to apply the fluid to the target surface.
- the application pad is mounted on the mounting core.
- the head also defines a dispensing channel that passes through the connection and mounting ends and defines a dispensing orifice.
- the present invention also defines a fluid dispenser comprising such a dispensing and dispensing head.
- the preferred fields of application of the present invention are those of cosmetics, pharmacy or even perfumery.
- US7883287 is already known which describes an application pad mounted on a mounting core which is connected to a connection bead mounted on a fluid reservoir.
- the core and the heel are traversed by a fluid product distribution channel which opens at a distributor orifice formed at the level of the pad.
- the core comprises a plastic insert which passes through the pad and which defines the distribution channel.
- the object of the present invention is to overcome the aforementioned drawbacks of the prior art by defining a distribution and application head whose architecture facilitates both the formation of the distribution channel and the design of the application pad, without complicating the mounting operation of the pad on the core.
- the distribution channel comprises an outlet section which is formed jointly by the mounting core and the fluid application pad.
- the output section runs along both an outer edge of the pad and an outer edge of the core.
- the outlet section comprises opposing inner walls which are respectively formed by the mounting core and the fluid application pad.
- the outlet section is formed between the core and the pad. It is realized only when the shoe is mounted on the core. Thus, a simple space between the core and the pad is enough to form the output section. Therefore, the pad can be in the form of a massive piece which is not traversed by any passage. Its surface treatment is greatly facilitated, since there is no place difficult to access, as is the case with a through passage.
- the formation of the distribution channel is also simpler, since it is sufficient to follow the pad, and no longer to bypass, as is the case in US9498042.
- the dispensing orifice is formed jointly by the mounting core and the fluid application pad.
- the output section opens between the core and the pad.
- the dispensing orifice extends on the outer periphery of the fluid application pad.
- the dispensing orifice may be annular and thus extend all around the fluid application pad.
- the mounting core and the fluid application pad may come into sealed contact at the dispensing orifice to form a self-sealing slot which opens with the fluid under pressure.
- the core may be made of a flexible material which will deform under the pressure exerted by the fluid product. It is also conceivable to make an application pad with a flexible material.
- the connecting bead and the mounting core define a longitudinal axis X
- the distribution channel comprises an axial section which passes through the connecting bead and the mounting core extending along of the longitudinal axis X.
- the axial portion can both be centered and rectilinear, which facilitates its formation, in particular by molding with a simple straight pin.
- the axial section is then connected downstream to the outlet section, formed between the core and the pad.
- the mounting core can form a receiving housing, advantageously by snapping, for the fluid application pad.
- the fluid product application pad may have a symmetry of revolution. No orientation of the pad is thus necessary during its mounting on the core.
- the connecting bead and the mounting core define a longitudinal axis X, the distribution channel extending along the longitudinal axis X of the connecting bead to the dispensing orifice .
- the head defines a longitudinal axis X which extends at least through the connecting bead and the mounting core, the application pad being attached and mounted mechanically on the mounting core along a mounting axis which extends transversely to the main axis.
- the application pad is made of a heat-transfer material, such as metal or ceramic, preferably having a density greater than 2, to give a feeling of coldness in contact with the skin. Materials with a density of 4 to 8 are the most effective.
- the mounting core is connected to the connection heel via a flexible connection section which is also traversed by the distribution channel. It can also be considered that this flexible section is formed by the heel or the core, or both together. This flexible section can be very simply in the form of a narrowing, able to confer a deformation capacity.
- the mounting core and the connecting lug are made integrally and are advantageously traversed only by the distribution channel. A realization by bi-injection is possible.
- the spirit of the invention lies in the fact of making part of the distribution channel, and at least the distribution orifice, between the core and the pad, so as to facilitate the production and surface treatment of the pad and to facilitate the formation of the distribution channel through the heel and the core.
- the pad When the pad provides a thermal effect (hot or cold), the fluid product is warmed up, because the output section runs along the pad.

- the dispenser essentially comprises three constituent elements, namely a fluid reservoir 1, a unit 2, which is here a pump actuated laterally, and a dispensing head 3 consisting of a nozzle 4 associated with an application pad 5.
- the fluid reservoir 1 can be of any kind (with or without air intake), of any shape and made of various suitable materials (flexible or rigid).
- a particular reservoir as shown in Figure 1A, comprising a cylindrical sliding shaft 10 associated with a follower piston 12 which moves in the drum 10 as the fluid product has been extracted.
- This type of tank makes it possible to keep the fluid product out of contact with the outside air.
- the follower piston 12 is disposed at one end of the barrel 10 when the reservoir is filled, which is opposite the other end of the barrel forming a neck 1 1 defining an opening communicating the interior of the reservoir with the outside.
- This is a quite conventional design for a follower piston type tank, but other types of tank can be implemented without departing from the scope of the invention.
- the pump 2 is a side-actuated pump comprising a pump body 20 defining at its lower end an inlet of fluid 21 in communication with the reservoir 1.
- the pump 2 comprises an inlet valve 22 and an outlet valve 23 between which is formed a pump chamber 24 comprising a lateral actuating wall 25 for reducing the internal volume of the chamber 24.
- the output 26 of the pump 2 is fixed and located in the axis of the pump and the distributor.
- Other types of pump can also be used in the context of the invention. You can even use a valve or a flexible tube instead of the pump.
- the head 3 is mounted on the outlet 26 of the pump 2, so that it undergoes no displacement during the actuation of the pump 2 by the lateral pusher 25.
- the dispensing head 3 comprises a nozzle 4 associated with an application pad 5.
- the tip 4 has a major longitudinal axis X and is advantageously made in one piece. It comprises a connecting bead 4t, a connecting section 41 and a mounting core 4n for the application pad 5.
- the connecting section 41 is optional or can be considered as an integral part of the heel 4t and / or the core 4n.
- This connecting section 41 may be rigid or deformable, in particular because it forms a narrowing between the heel and the core. When it is deformable, this makes it possible to confer a certain degree of freedom of movement on the shoe 5.
- the connecting heel 4t forms a connecting sleeve 41 which is engaged by force or by snapping into the upper part of the pump 2 which defines the exit 26.
- the tip 4 is made of plastic material (PE or PP for example), while the application pad 5 is advantageously made of a hard or rigid heat-transfer material, such as metal, ceramic, a mineral material, etc. , able to confer a sensation of cold in contact with the skin.
- the part 5 has a large wall thickness to increase its thermal inertia.
- the density of the heat transfer material is greater than 2 and preferably between 4 and 8.
- a non-heat-sensitive pad, for example PE or PP can also be implemented.
- the mounting core 4n forms a receiving housing L in which the application pad 5 is engaged or encased.
- the housing L comprises a flexible annular lip 43 at its inlet, and a fixing chamber 44 at its bottom. Between the chamber 44 and the lip 43, the housing defines a frustoconical wall 42 having a solid angle of the order of 90 °, or slightly more, for ease of demolding issues.
- the application pad 5 advantageously has a symmetry of revolution and a shape similar to a router. More specifically, the pad 5 comprises an application surface 51, which can be flat or curved (convex). This application surface has the shape of a domed disc or a flattened dome. The pad also comprises a frustoconical wall 52 of similar or identical shape to that of the housing L. Between the application surface 51 and the frustoconical wall 52, the pad forms a substantially cylindrical edge 53 against which the flexible lip 43 rests. to create a sealed annular contact. Finally, the shoe 5 comprises a fixing pin 54 which is engaged by force, glued, welded or snapped into the fixing chamber 44 of the housing L.
- FIG. 2A It can be seen in FIG. 2A that there remains a gap between the two opposite frustoconical walls 42 and 52 which extends from the fixing chamber 44 to the flexible lip 43 which bears tightly against the edge 53.
- the dispensing and application head 3 also comprises an internal distribution duct which allows the fluid product to be conveyed from the outlet 26 to a dispensing orifice 50, which is formed here at the level of the leaktight contact between the lip 43 and the song 53.
- This dispensing orifice 50 extends around the pad 5 and thus has an annular shape. It behaves like a self-sealing slot that is closed at rest and opens to create an outlet passage under the pressure exerted by the fluid product.
- the dispensing orifice 50 forms the outlet of the distribution channel C.
- the dispensing channel Upstream of the dispensing orifice 50, the dispensing channel comprises an outlet section Cs formed by the space between the two opposite frustoconical walls 42 and 52.
- the distribution channel comprises an axial section Ca which extends through the nozzle 3, advantageously centrally and rectilinearly.
- the axial section Ca opens into the housing L at the frustoconical wall 42.
- the outlet section Cs are formed jointly by the mounting core 4n and the pad 5.
- the outlet section Cs comprises opposite internal walls which are respectively formed by the mounting core 4n and the application pad 5.
- the dispensing orifice 50 constitutes the ultimate or end portion of the outlet section Cs.
- the endpiece 4 is of a very simple design with the axial section Ca centered and straight and the housing L widely open and well oriented to ensure easy demolding.
- the pad 5 is completely symmetrical of revolution and has no through passage. Then, the outlet section Cs extends over a large surface of the pad 5, so that the fluid can quickly take the temperature of the pad.
- the flexible lip 43 acts as an outlet shutter, allowing a better preservation of the fluid in the head 3.
- the mounting of the pad 5 in the housing L, along an assembly axis Y which is transverse to the X axis, is very easy to automate.
- the flexible lip 43 it is possible to dispense with the flexible lip 43, so that the dispensing orifice would then be formed by an annular slot open permanently. It is also possible to provide a rigid lip which is interrupted locally to form one or more orifice (s) distribution.
- the outlet section Cs is formed between frustoconical walls 42 and 52: other shapes may be provided for the opposite walls, insofar as they define between them a space which leads from the axial section Ca to the dispensing orifice.
- FIG. 4A and 4B there is shown a dispensing and dispensing head 3a according to a second embodiment of the invention.
- the integral piece 4a comprises a connecting heel 4t and a connecting section 41 which may be identical or similar to those of the first embodiment of Figures 1A to 3B.
- the mounting core 4n is different in that it forms a first extended application area portion 41a which is delimited in its upper part by a profiled edge 46, which has a notch 46a, forming part of a dispensing orifice 50a.
- the core 4n comprises a mounting stud 45 for the application pad 5a.
- This stud 45, as well as the extended application area portion 41a, has an inclined orientation relative to the longitudinal axis X of the tip 3a.
- the application pad 5a in this second embodiment, is in the form of a rounded cap or cap which internally defines a mounting housing 55 adapted to receive the mounting stud 45.
- the pad 5a defines a second portion extended application surface 51a which is delimited in its lower part by a complementary profiled edge 56 which is complementary to the profiled edge 46 of the core 4n, except at the notch 46a, where the complementary profiled edge 56 is peeled off. 56a of the notch 46a to form another part of a dispensing orifice 50a.
- the dispensing orifice 50a is jointly formed by the core 4n and the shoe 5a, since the shoe 5a is attached to the core 4n by a sliding movement along a mounting axis Z which is oriented from transversely to the longitudinal axis X.
- the end piece 3a is traversed by a distribution channel Caa (shown in dotted lines in FIG. 4A), which is both centered on the X axis and straight from one end to the other, so that the dispensing orifice 50a is located on the axis X. Moreover, this dispensing orifice 50a can be considered as the ultimate output section of the Caa distribution channel.
- This head 3a is formed jointly by the core 4n and the shoe 5a, substantially equally.
- the edges 46 and 56 meet to create a surface continuity. It can be said that the pad 5a completes the core 4n, or vice versa. Together they form a kind of rounded pebble with no sharp edges.
- FIGS 5A and 5B there is shown a dispensing head and application 3b according to a third embodiment of the invention.
- the one-piece endpiece 4b comprises a connecting bead 4t and a connecting section 41 which may be identical or similar to those of the first and second embodiments.
- the mounting core 4n comprises a mounting stud 45b for the application pad 5b, as well as a lower flexible lip 47 which comes into sealing contact with a lower edge of the pad 5b, thus forming a self-sealing slot, as in the first embodiment.
- the application pad 5b in this third embodiment, is also in the form of a rounded cap or cap which internally defines a mounting housing 55b adapted to receive the mounting stud 45b.
- the pad 5b and the core 4n have an inclined orientation relative to the longitudinal axis of the tip 4b.
- the shoe 5a is attached to the core 4n by a sliding movement along a mounting axis which is oriented transversely with respect to the longitudinal axis X.
- the tip 4b is crossed by a section of distribution channel Cab which is both centered on the X axis and straight.
- This section Cab opens downstream on an outlet section Csb, which is formed jointly by the core 4n and an inner face of the pad 5b.
- This section Csb extends downwardly to the lower lip 47, which is in supple flexible support on the pad 5b.
- Figures 6A and 6B show an alternative embodiment of Figures 5A and 5B.
- the tip 3c and the pad 5c may be identical or similar to those of FIGS. 5A and 5B, except that the core 4n no longer forms a flexible lip 47 in sealing engagement with the pad 5b, but a rigid edge 47c disposed away from the pad 5c, so as to form between them a dispensing orifice 50c in the form of an elongated curved slot.
- Figure 7 shows an alternative embodiment of Figures 6A and 6B, which is characterized in that the dispensing orifice 50d is formed by a local depression of the pad 5d, which is out of contact with the core.
- the distribution channel is formed jointly by the mounting core and the applicator pad, this channel part being able to be limited to the single dispensing orifice, as in FIG. embodiment of Figures 4A and 4B.
- the dispensing channel never crosses the applicator pad, but runs along it. It is thus easier to treat the pad by applying an inert coating, which is necessary, especially when made of Zamac®. Since all surfaces of the pad are easily accessible external surfaces, the surface treatment can be complete and uniform.
- the distribution channel is rectilinear and centered axially at the tip. It is only the output section that can extend out of the axis.
- the dispensing orifice opens out at an outer periphery of the applicator pad. It can be considered as the terminal part of the exit section.
- the dispensing orifice may be located on the longitudinal axis of the head, as in the embodiment of Figures 4A and 4B, or offset with respect to this axis.
- the dispensing orifice may be punctual, as in the embodiments of Figs. 4A, 4B and 7, elongate open, as in the embodiment of Figs. 6A and 6B, elongate closed, as in the embodiment of Figs. 5A and 5B, or annular open or closed, as in the embodiment of Figures 1A and 3B.
- connection bead is connected directly or indirectly to the mounting core.
- the connecting section is rigid or flexible.
- the tip is preferably monobloc and mono-material, but multi-material designs by mounting or bi-injection are also possible.
