Description

Application head comprising an application element and valve

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an application head for application of a product, and more particularly to cosmetics.

Application EP 1 803 368 discloses a packaging and application device for cosmetics comprising an application element introduced in a housing aligned at the first end of the device, the application element being adapted to be fed from the container by means of a valve. The valve opens in response to the user pressing an active surface disposed behind the device.

Application EP 1 514 492 discloses a device for packaging and dispensing cosmetics, wherein the applicator member is disposed in the housing, the product is supplied from the container by the valve, and the valve is opened by the movement of the container relative to the housing.

Application FR 2 829 115 discloses a packaging and application assembly of a cosmetic comprising a container for receiving a product mounted in a portion defining a housing for receiving an applicator. The housing is supplied with the product from the container by a valve, which opens as soon as the user applies pressure to a closed cover integrally formed with the applicator as soon as the applicator is placed in the housing. In such a device, it is necessary to use the device in two stages because the product is dispensed when the applicator closes the housing and is not accessible to the user. The first step is to feed the applicator and the second step is to attach the product to the surface to be managed.

US 2002/0014246 discloses a brush having a plurality of bristle arranged parallel to the product distribution axis. The hair is moved by the tip and the position of the housing of the body of the brush is moved to create a fluid connection between the hair and the product container.

EP 0 786 215 discloses an application head which includes an application element that is permeable to the product and is mounted to move in the head, the movement of which may result in the distribution of the product.

There is a need for better improvement of the application head for applying the product to keratin materials such as, for example, hair in order to enjoy new effects and to achieve better results and / or more simplicity.

There is also a need to have an application head that can be used simply and practically.

It is also necessary, if necessary, to have an application head which can be suitably used inside the hair care device, in particular the electric hair care device.

According to one aspect, an object of the present invention is to provide an application head for applying an article.

This application head includes a receiving area; An application element disposed in the receiving area, the application element being in the receiving area and in contact with a surface to be permeated with the product and to be managed with the product; An application head body comprising means for establishing fluid communication between the receiving area and a container containing a product to be applied; And a valve capable of sealing the means for establishing fluid communication.

The valve is located in the receiving area when the application element is mounted such that 1) a setting of the application element in the receiving area accompanies the opening of the valve, or 2) moves and / or deforms in the receiving area. The movement and / or deformation of the application element is in such a way that it is in contact with the surface to be managed and accompanied by the opening of the valve.

The receiving area can be partitioned by the housing of the application head.

The means for establishing fluid communication can have a product inlet opening that can exit into the receiving region.

According to one embodiment, the present invention allows for automatic opening and closing of the valve seal that seals the product inlet when the applicator element is placed in place, thereby simplifying the use of the applicator head and reducing accidental loss of the product.

The presence of the valve may allow the closing of the fluid communication establishing means in the absence of the application element, thereby facilitating cleaning of the application head and the application element.

In another embodiment, when the valve is mounted so that it can be disposed and / or modified in the receiving area, the present invention allows for the distribution of the product in response to the pressure exerted on the application element by the area to be managed. The application element can transfer pressure to the valve and thus control its opening. This allows the application element to provide the product purely during application.

The head is configured such that when the application element is in the position of the receiving area, the application element can pressurize or pressurize the valve to open it.

In addition, the use of valves allows the product to be preserved in the absence of an application element.

In a useful manner, the application element is mounted to the receiving area in a movable manner, for example allowing the product to be reduced in porosity or replaced by hygiene by drying.

The application element is for example mounted rotatably in the receiving area to allow rotational engagement with the surface to be managed.

The application element may have voids and may saturate into the product due to capillary action and release the product at the time of application to the surface to be managed by capillary action and / or by pressing the application element against the surface to be managed. Can be.

The application element may be void and mounted in a movable manner in the receiving area.

As a variant, the application element is a thin through screen embodied in a non-porous material. Such an application element can be removed and cleaned by the user between two uses of the application head.

The receiving area may have an elongate shape along the longitudinal axis, and when the application element is in the position of the receiving area, the application element of the valve may extend along the longitudinal axis parallel to the longitudinal axis of the receiving area.

The receiving area may have an elongate shape along the longitudinal axis, parallel to the longitudinal axis and the valve and the application element extending along the longitudinal axis perpendicular to the product dispensing axis when the application element is in the position of the receiving area. "Product distribution axis" means the axis through which the product is distributed by the head when leaving the supply opening.

As a variant, the valve is for example a rotary valve extending about an intersecting axis which is symmetrical about the longitudinal axis of the receiving area. The axis of symmetry is, for example, at least 45 degrees, for example 90 degrees, with respect to the longitudinal axis of the receiving area.

The application element may extend to a length exceeding that of the valve and may extend along the sides of both sides of the valve when the application element is in the position of the receiving area.

The application element may be embodied to promote dispersion of the product by capillary action, in the longitudinal direction when it is porous. This, for example, reduces the risk of product excess on the surface of the porous application element, which result in dripping of the product.

The application elements are for example wicks, felts, sinters, in particular thermoplastics or ceramics, sponges with open cells or semi-open cells, layers in which one or several of these materials overlap It is embodied in an elastomeric body with ones.

The application element can be obtained from polyolefins, in particular from polymers such as polyethylene or polypropylene, polyamides, EVA, polyvinyl acetate, polyethers or polyurethanes and polytetrafluoroethylene (PTFE).

The application element may comprise porous fibers, such as, for example, polyethylene terephthalate (PET), polyethylene (PE) or polypropylene (PP), which fibers are co-extruded in the longitudinal direction of the application element. . Such fibers can facilitate the dispersion of the product and make the application more homogeneous by capillary action in the application element over its entire length.

The application element can be implemented using natural fibers, for example cotton and / or linen.

The permeability of the application element at the longitudinal ends to the product may be less than the permeability of its surface extending between the ends. This can reduce the risk of product flowing into the longitudinal ends of the application element. For example, when hot-cutting in the longitudinal direction of the material used to implement the application element, the application element forms a skin that cannot penetrate into the product, thereby locally bonding the material of the application element to the longitudinal ends. It can be made impermeable.

The general form of the application element may be a rotatable semi-cylindrical and bear its base against a receiving area that may be approximately planar.

If necessary, projections may be implemented in at least one area containing the area or face of the application element facing that area in order to prevent the risk of product spillage elsewhere in the application element. Thus, it is possible to implement a lip that projects slightly outward around the opening enclosed by the valve from the bottom of the housing described above.

The application element can be held in various ways in the receiving area, in particular in the housing. The application head may be configured such that the application element is mounted by sliding. The aforementioned housing is for example open at two longitudinal ends, and the application element can be introduced by either of the ends. The application element can be replaced, for example, by pushing and releasing the application element currently present by the new application element.

The fixing of the application element to the storage area may involve, if necessary, at least one elastic deformation of the application element and the storage area, for example a ratchet coupling of the application element to the storage area. This can improve the way the application element is held in place. In an exemplary embodiment of the invention, the valve may be ratcheted to the corresponding protrusion of the application element. Such a ratchet bond can be felt by the user and can inform the user that the application element is in the correct position. Such a valve may rub against the applicator element and contribute to retaining the applicator element in the housing.

The width of the housing containing the applicator element can be about the same as that of the applicator element, so that it can be retained in the applicator element by friction.

The application head may comprise at least one protrusion, may guide and / or comb the hair, promote retention of the product or participate in its application.

While using the applicator head, the hair may generally be in contact with protrusions that may maintain it in the management area of the applicator head if there is a tendency to receive some product. The protrusions may or may not be identical. The application head includes, for example, successive projections between the end projections of different shapes, for example, to allow the user to determine the extent of the management area of the application head in a better way.

The projections, their at least special projections, may be located at a relatively small distance from the valve, for example less than or equal to 2 mm.

The aforementioned protrusions may extend to at least one side of the valve, for example, to both sides of the intermediate longitudinal plane of the valve. Thus, the hair can be guided before and after engagement with the application element. The presence of the projections downstream of the application element can make the application of the product more homogeneous with respect to the direction of movement of the hair relative to the application element, thereby promoting diffusion in the hair. The presence of the upstream protrusions can facilitate the wick to contact the application element in a flat manner.

Compared with the groove or the bottom of the grooves formed between the protrusions and the portion receiving the hair, the height of the protrusions may be at least 3 mm, more preferably 8 mm.

The application head comprises, for example, a number of teeth or ribs that are directed to intersect with respect to the longitudinal direction of the housing, for example to be perpendicular to the longitudinal axis of the housing. The protrusions are for example a tooth that extends along one or two rows of the length of the application element or a rib that may or may not extend the full width of the application element described above.

The protrusion or protrusions may contribute to retaining the application element in the housing, the housing being at least partially partitioned by the protrusion or protrusions. When the general form of the application element is a rotating semi-cylinder, each of the aforementioned ribs may be curved close to or slightly smaller than that of the application element, so that the application element is slightly pressed against the bottom of the housing. Risk of leakage at the junction between the housing and the housing surface can be reduced.

The protrusions or protrusions described above can be implemented, for example, by molding of thermoplastic material such that the wall partitions at least a portion of the seat of the valve and / or the body of the application head. The protrusion or protrusions may be added to the body of the application head. If necessary, the protrusions or protrusions are moved by a support fixed in a detachable manner to the body of the application head, for example allowing the protrusions or protrusions to be changed depending on the product or care and / or hair properties to be performed. do.

The application element can be embodied, for example, as a convex smooth surface which comes into contact with the keratin materials. The protrusions may be formed in the application element, for example in the form of a tooth. Such protrusions may be distributed over the entire length of the application element.

The protrusions increase the contact surface with the hair.

The fluid communication establishing means includes a channel inside the body of the application head that allows fluid communication between the receiving area and the container.

It is an object of the present invention according to another aspect of the present invention to provide an assembly for the application of a product.

The assembly includes an application head defined as described above; And a container containing the product to be applied.

The volume of the container contains 5-20 mL and, if necessary, allows all hair to be managed.

The container may be permanently present at the application head. As a variant, the container can be removed and in this case can be formed by a cartridge that can be made integral with the application head, for example. The cartridge may be in various forms such as, for example, in the form of a flask. The application head may include a housing for receiving the cartridge. The cartridge can be moved by a valve if necessary. The cartridge may comprise some or all of the aforementioned projections or projections.

The cosmetic product can be, for example, a capillary product, in particular a product which can be applied before, during or after thermal management of the hair. This care is care that makes hair soft or tortuous, for example by contacting the hair to the surface of something such as tongs or curling irons.

The product may be a product for application to the skin or lips, for example, a make-up product or a care product.

The application head may, if necessary, comprise a protective cover for the application element when the application element is not used. Such a cover may, for example, be removable and close the space to accommodate the application element in a tight or non-tight manner.

The receiving area may be configured to facilitate replacement of the application element by the user as the application element may be removed and the protrusion or projections and / or a portion of the application head may be introduced.

The assembly may comprise a fixing means in a device for care of hair, in particular in one part of the electrical device, for example in one arm of a smoothing chopstick or hair iron.

The securing means may comprise a handle which is hooked at both sides of the arm and may leave an unheated surface on the arm. The handle may be hollow, at least partially partition the container to increase its capacity, and reduce the space occupied by the assembly comprising the application head at the same capacity.

The container may comprise a filling opening and plug means for closing said opening, for example a plug. This allows the container to be filled without separating it from the application head.

The valve can be implemented in a variety of ways, such as, for example, integrally molded with the resilient return member of the valve in a position to seal the dispensing opening. The return strength of the elastic return member can be set in advance according to the properties of the application element, for example. The valve includes, for example, a rigid plate actuated by an elastic return member.

As a variant, the valve comprises a flexible, deformable wall.

The other member has, for example, a hot surface which allows the hair to be contacted there before or after application of the product in the same manner as the application head.

The device comprises, for example, a portion of the arm to which the assembly can be fixed.

Another object of the present invention according to another aspect of the present invention, which may be independent or combined with those mentioned above, is to provide an electrical device for hair care. The electrical device for hair care includes a portion to which the assembly for application is fixed in a removable manner, and has an application head and a container for receiving the product to be applied to the hair and the application element.

The assembly may be secured by, for example, a handle on the arm of the device, which handle is left without the heating surface of the device. The handle is hollow and at least partially partitions the container. The application head may have any of the features described above.

Another object of the present invention, independently of or in combination with the foregoing aspects, comprises a porous application element for an application head having any of the features described above, the application element having a cavity-oriented parallel to its longitudinal axis. It comprises a strand of extruded porous fibers, the two ends of which do not penetrate into the product and, in particular, comprise a skin obtained by fusing to the fiber material in a local manner.

10 is a cross-sectional view taken along the line XX of FIG. 9.

As shown separately in FIG. 2, an assembly 1 for the application of a product according to a preferred exemplary embodiment of the invention comprises an application head 2, an example of an electrical device for hair treatment. For example, it may be mounted to a hair smoothing tong or curling iron.

Such a device comprises, for example, two arms 10, only one of the two arms is partially shown in FIG. 1, which arms can be located close to the hair to be managed.

At least one of the arms 10, preferably each arm 10, is provided with a heating surface, which, in use, can move the hair and make contact with the heating surface.

The heating surface is raised, for example, to a temperature in the range of 100-180 ° C., and the heating surface is partitioned by metal pieces or ceramic pieces, which can be flat and smooth, for example. If necessary, steam may emanate from the surface of the heating surface. The heating surface can be rounded or wavy.

When the arms 10 come close to each other, the hair passes between the facing heating surfaces.

The present invention is not limited to the use of the assembly 1 only for hair care devices having the purpose of smoothing or curling the hair.

The assembly 1, in particular the application head 2, can be used alone, for example, to apply the product to the hair independently of other treatments. Thus, the product may be, for example, a dyed or bleached product for hair care or hair fixation.

The assembly 1 is mounted such that it can be coupled to either of the arms 10, for example by sliding of the arm 10. This mounting can be eliminated to facilitate packaging and / or cleaning of the assembly 1, in particular the application head 2.

In the example shown, the assembly 1 has a handle that can be mounted to the arm 10 and the handle 3 is disposed to face each other to hold the assembly 1 on the arm 10. With vertical parts 4, 5 which are finished with edges 6.

The bottom of the space 7 partitioned between the vertical parts 4, 5 is heated in contact with the back of the arm 10, for example, as shown, for example, a rib or boss, as shown. It includes projections 8 which prevent the assembly 2 from moving by friction with the arm 10 at the required position of the surface of the face. Thus, one and the same fixation of the hair can move over the heating surface of the arm 10 simultaneously over the application head 2.

Of course, other fastening means for mounting the assembly 1 to the arm 10 by, for example, other forms of fastening, such as ratchet engagement, bayonet form or fastening by loose elements such as screws or elastic fastenings. This is possible. The assembly 1 is installed in the hair care device in such a way that it cannot be dismantled by the user, in which at least a portion of the assembly 1 is integrated with a molding material, for example in at least a portion of the arm 10. Can be.

Preferably, the assembly 1 is incapable of movement relative to the arm 10 when the assembly is in use in the device. In one variant, not shown, the assembly 1 is movable relative to the arm 10 of the device, so that the assembly 1 is between an active position that can impart action to the hair and an inactive position that activates only the heating surface or heating surfaces. The user can move it.

The product, which can be applied to the hair by the application head, is received in the container 20 of the assembly 1 and can be filled by the user using a filling opening provided with a plug 21 in the example shown.

The container 20 may, for example, extend up to a portion of the volume of the handle 3 to increase its capacity. This volume is, for example, in the range 5-20 mL.

The application head 2 has an application surface 22 that can contact the hair.

The application head 2 is present on one side of the application surface 22 as semi-circular ribs, guided, styling and / or applied to the hair, which can be spaced apart from each other and partition the space 24 therebetween. It may include protrusions 23 for. Here, the hair can enter the spaces. The spaces 24 are directed in a manner perpendicular to the longitudinal axis of the application surface 22 in the example shown.

In the contemplated example, the application head 2 has three end projections 25 which delimit the management portion of the application head 2 in the longitudinal manner. The tip protrusions 25 may, for example, be larger than the protrusions 24 and may be present in a curved form, as shown. In a variant that is not shown, the tip protrusions 25 may be replaced by missing or complete walls or other shape of protrusions.

The spacing between the end protrusions 25 is designed according to the width of the lock of the managed hair, for example, in the range of 4-40 mm, and the number of the protrusions 23 is for example. , 2-20 pieces, and the gap between two adjacent protrusions 23 is, for example, 1-4 mm.

A receiving zone defined by the housing 32 is disposed below the protrusions 23 to receive the application element 70. This application element 70 is for example formed of any porous material. For example, porous application elements formed by co-extrusion of thermoplastic fibers of PE, PET or mixtures of these PETs are used.

The longitudinal ends 71 of the application element may be made incapable of penetrating into the product, for example, by melting a fibrous material at the ends or forming an impermeable skin by means of a hot cutting tool or a laser.

The shape of the application element 70 is a cylinder in which the generatrix is parallel to the longitudinal axis of the housing 32 and a semi-cylinder with a radius equal to or slightly larger than that of the rib 23. It can be held inside the housing 32 by friction.

In the example described, the application head 2 comprises a body 9 provided with a channel 29 therein to allow fluid communication between the container 20 and the housing 32. As shown in FIG. 3, the product received in the container 20 is moved to the application element 70 by a channel 29, and in the example shown, of the base of the application element 70 by the opening 30. It opens underneath the protrusions 23 of the housing 32 on the opposite side.

The opening 30 is elongated along the longitudinal axis X approximately parallel to the longitudinal axis Y of the arm 10, as shown in FIG. 1.

The opening 30 is sealed by the valve 40, in the absence of the application element 70, the valve 40 protruding into the housing 32 so that the valve 40 can be activated by the porous application element 70. Has (41).

In the example shown, the valve 40 includes a rod 43, one end of which is supported by the head 41 and the other end serving as a guide of the spiral spring 44 supported by the retaining ring 45, and the retaining ring ( 45 is freely mounted on the rod 43 and ratcheted to the inside of the projection 46 of the container 20.

In the example shown, the opening 30 is implemented through the wall 34 of the body 9 of the application head. In cross section, the shape of the head 41 of the valve 40 is streamlined, and the coil spring 44 is fixed by acting on the wall 34 to close the opening 30.

The longitudinal ends of the head 41 of the valve 40 are inclined toward each other to move away from the bottom of the housing so that when it is introduced into the housing, the application element 70 is supported against the valve without pushing it in. Can be avoided.

The wall 34 may be molded, for example, of the same material or of a different material integrally with the protrusions 23. As a variant, the projections 23 can be added to the body of the application head 9, for example by means of adhesive, ratchet coupling, fitting coupling, welding or one or several additional fastening parts. Alternatively it may be fixed to the body of the application head. In a variant that is not shown, the projections 23 can be mounted in a movable manner on the body 9 of the application head, so that, for example, the projections 23 are not affected by the nature of the hair or the care to be performed. Allow to change accordingly. The protrusions 23 may be molded to a support that can be secured to the body of the application head by various means, for example by ratchet engagement or sliding positioning.

The flow of product towards the application head 70 when the valve 40 is open can be by gravity, and the application head 2 is directed towards the space 32 facing the floor or sideward, for example, in use. It is. If necessary, the flow of the product can be assisted by volume reduction inside the container 20, for example as a result of the user deforming the wall, using a piston or deflating the deformable elastic pocket.

The condition of the surface of the protrusions 23 may facilitate the application of the product to the hair, for example it may be partially covered by flocking.

The valve 40 may be implemented differently, which may be beneficial as shown in FIG. 4, and may implement the coil spring 44 of the valve in a sealed position by molding integrally with the rest of the valve, for example. For example, a spring 44 connected to the gear 39 of the valve or ratcheted to the inner protrusions 52 of the container 20 connects to the head 41 of the valve.

The opening 30 may be formed to the thickness of the wall 34 of the body of the application head, as shown in FIG. 3, or in a modified example, the body 9 of the application head, as shown in FIG. 4. It can be formed between the lips 56 of the.

In the above-described embodiment, the container 20 is permanently fixed to the application head 2, and like the protrusions 23, the wall of the container 20 is for example of the main body 9 of the application head. It is embodied by being molded integrally with the wall 34.

In a variant not shown, the container 20 is in the form of a cartridge mounted in a removable manner to the application head 2, the application head comprising a housing adapted to receive the cartridge.

If desired, the cartridge may comprise a container 20 as well as an associated valve 40, and once the cartridge is mounted, the application head 2 may be inserted into a housing 32 containing the application element 70. It may be arranged to allow it to protrude.

To use the application head shown in FIG. 1, the user places the hair between the arms 10 to expose the heating of the heating surfaces. The hair is located between the protrusions 23, 25 and extends between the ends 71, where it comes into contact with the surface 72 of the porous application element 70 from which the products are taken.

The invention is not limited to the examples shown.

An assembly for the application of a product implemented according to a preferred exemplary embodiment of the present invention, in particular an application head, can be used for application related independently of the electrical device for hair care.

The application head 2 may comprise, for example, a portion that is aligned to be mounted to a flask functioning as a container, such as screw-connected to the collar of the flask, or fixed to the flask by a band provided with ratchet means. .

The application head may be mounted to the spray can.

The application head may be embodied so that if necessary, no part covers the application element other than to act to hold it to the application head.

Such an example of an application head that does not include the end protrusions 25 is shown in FIG. 5.

The valve 40 may be implemented in a variety of ways and may extend less than half of the length of the porous application element 70, for example, as shown in FIG. 6.

The application element 70 may not move completely relative to the receiving area 32 when the head is used to apply the product.

As a variant, as shown in FIG. 7, the application element 70 can be mounted so as to be displaceable relative to the receiving area 32, thereby pressing the valve 40 to reach the product when pressure is applied thereto. .

As another variant, as shown in FIG. 8, the application element connects the fixing portion 70a fixed to the receiving area 32 and the fixing portion 70a to the central portion 70c of the application element 70. It may include a deformable portion 70b and may be pressurized to activate the valve 40 in use.

In the example shown in FIGS. 9 and 10, the application element 70 can be mounted in a rotatable manner with respect to the receiving area 32.

In the example described, the body of the application head comprises two wings 80 which regulate the extent of the management of the application head 2 in a longitudinal manner, with each wing 80 provided with an opening.

In the example described, the application element 70 includes pins 84 that engage corresponding openings at their respective longitudinal ends.

The pin 84 may be implemented integrally with the application element 70. As a variant, the pin 84 is replaced by two longitudinal ends of the through-shaft and the application element 70 is integral with the shaft.

As can be seen in FIG. 10, when the application element 70 presses the valve 40, the product can be dispensed through passages 42 disposed in the head 41 of the valve 40.

Other variations are possible without departing from the scope of the present invention.
