EP2760310B2 - Care-substance applicator for applying a care substance to a strand of hair, and care-substance cartridge therefor - Google Patents

Description

The invention relates to a hair styling device with a care applicator for applying a care substance to a strand of hair.

In order to support a hair shaping, care substances are sometimes introduced into the hair. These may assist the hair styling process or are used to condition the hair. To carry out the molding process of the hair hair styling devices are used, for example, so-called Straightener or curling irons. Such hair styling devices have a heated hair surface. A straightener has two such hair shaping surfaces, between which there is a hairline nipple. The hair shaping surfaces of a Straighteners are articulated in the manner of a pair of pliers against each other adjustable. For hair styling typically a certain pressure and a certain mold temperature is needed. To support the molding process, it may be appropriate to previously moisten the forming hair with a care substance or with water, so that water is to be understood as a care substance in the sense of these statements.

If care substances are supplied to the hair in connection with a hair shaping, this takes place before the molding process to be carried out with the hair styling device. The care substance (s) are sprayed on the hair or, if these are foam or gel preparations, massaged into the hair. However, this means that the entire hair or part of the hair to be formed is to be treated in a first step with the care fabric, to be subsequently molded with the hair styling device with heat. Treating the shaped hairs with a conditioner to condition them after the hair-styling process is possible only in the form of a firming spray so as not to interfere with the hair-setting that has been made. applied is such a care spray after completion of the entire hair shaping process, ie: after the entirety of the hair to be formed have been formed. Therefore, a limited to certain strands selective application of care materials after perfect molding process is not or at least not readily possible.

Furthermore, an administration element is provided, which has an eg sponge-like structure for receiving the liquid coolant. By suitably guiding the delivery member to the container, the means for operating are actuated, whereby liquid coolant flows out through the valve and is received by the delivery member. After removal of the administration element, the valve being closed again, a cooling effect is produced by evaporating the coolant.

WO 2004/041021 A discloses a hair treatment system comprising a hair styling device having two hingedly connected arms and contacting elements respectively disposed thereon, a mounting frame for placement on a contacting element, and an appliqué which can be secured by means of the mounting frame. The application cloth may be before or after attachment with a means for Hair treatment to be soaked. In operation, the hair is trapped between the two arms, with the agent being released from the appliqué into the hair.

FR 2 953 376 discloses a system for applying a cosmetic product to a strand of hair with an applicator having a forceps-like applicator for guiding the strand of hair. The application device is pipette-like with a reservoir and adjoining cannula, at the end of which the applicator is located, which may have, for example, bristles or an absorbent material. The system further includes a container for the (liquid or gelatinous) cosmetic product into which the application device can be immersed to fill by actuation of the reservoir's pipette. For application, the application device is removed from the container, wherein the cosmetic product can be dispensed via the applicator by operating the pipette.

Starting from the in WO 2004/041021 A described hair treatment system, the invention is therefore an object of the invention to ensure a trouble-free filling of the care applicator with the care and safe storage of the care fabric in the care applicator.

This object is achieved according to the invention by a hair styling device with a care applicator having the features of claim 1.

The care applicator is refillable with regard to its stored therein care product. For this purpose, one uses a care fabric cartridge, which has a care carrier, in which the care substance is maintained. The care substance can be kept ready for dispensing in the care carrier, that is, in its state of aggregation, with this to be applied to the hair. The care substance is held in the care carrier. Depending on the configuration of the care substance applicator or of the care substance to be applied, the care substance may be held in the care carrier in liquid, gel or solid form. Sometimes a state change the care substance brought about before the care product is supplied to the hair to be conditioned. This may be, for example, a heating of the care substance in order to bring it into its vapor phase, so that a care application can be carried out in the vapor phase. The care carrier is typically a textile material, such as a fleece or a felt. The use of an open-cell foam is conceivable for producing the Pfleffoffträgers. For handling the care carrier this is associated with a support body, by which the care carrier is kept dimensionally stable at least in the insertion direction of the cartridge in a trained as a cartridge receiving care fabric reservoir. This serves the purpose that when the care fabric cartridge is inserted into such a cartridge receptacle, the care substance from the care carrier is not pressed out, or at most only minimally. This applies especially when the care substance contained in the care carrier is liquid or gel. Thus, the support body of the care fabric cartridge gives the necessary for their handling for insertion into the care fabric reservoir dimensional stability. To touch the care fabric cartridge is a typically integrally formed on the support body handle. This can be performed, for example, shank-shaped or in the manner of a tab. The latter embodiment will be preferred when the support body for locking and unlocking thereof within the cartridge receptacle of the care applicator has to be rotated. Can be provided a lock between the support body of the care fabric cartridge and the cartridge holder.

Part of the support body may be a care carrier in the insertion direction of the care fabric cartridge in the cartridge receptacle against deformation protective flange.

The care applicator can be designed in such a way that the care substance to be applied to a strand of hair is introduced into the hair in a contacting or contactless manner. In the former case, the hair contacting the care substance application outlet is preferably guided past a closure body which is permeable to the care product and which may well also be part of the care substance carrier. In the case of a non-contact application of care material, heat can be used to apply the conditioner in vapor form to the hair. In such an embodiment, it makes sense to preheat the care substance to be applied, to a temperature only slightly below its evaporation temperature. If such a configuration is provided, it is provided according to an embodiment to arrange the care fabric applicator with respect to the heating device of the hair styling device in such a way that it preheats the care carrier in the care fabric reservoir at least in the region of the care substance application outlet. Above its vaporization temperature, the conditioner is exposed to heat radiated by the hair thermoformed with a hair styling device into the care fabric application outlet. In such an embodiment, self-regulation of the care substance application takes place.

The above-described care applicator for applying a care product to a strand of hair is not only easy in its training and production, but also at least partially recyclable by the described cartridge design. With this concept care product cartridges can easily be exchanged for one another, even without a first care-substance cartridge being emptied. This offers the possibility, depending on the application, the desired care fabric, stored in a care carrier of such a cartridge to use in the care applicator. To distinguish different care substances can be provided to mark the support body and / or the care carrier in different colors. Then, a specific color of the wearer body and / or the care carrier of the care fabric cartridge is assigned to a specific care substance. The person working with the care applicator can then readily recognize which care substance is in the care applicator.

A hair styling device 1 is designed as a so-called Straightener and thus in principle for straightening hair. The hair styling device 1 has two articulated arms, which are adjustable against each other like pliers. In FIG. 1 the hair styling device 1 is shown only with one of the two arms 2. Each arm carries at its free end on the facing to the other arm side of a mold 3. These are each an electrically heated mold plate with a flat, smooth surface. Thus, in the illustrated embodiment, the surface of the forming tool 3 forms the hair shaping surface on which, in cooperation with the complementary forming tool of the other, in FIG. 1 Not shown poor hair can be shaped.

The arm 2 of the hair styling device 1 carries on its two longitudinal sides in each case a care applicator 4, 4.1. In the following, the care substance applicator 4 is described. The care applicator 4.1 is constructed identically. The care applicator 4 of the illustrated embodiment consists of a housing 5, in which a cylindrical, the longitudinal extent of the housing 5 following care fabric reservoir 6 is introduced. The front, in FIG. 1 recognizable frontal opening 7 of the care fabric reservoir 6 is used for insertion and removal of a care fabric cartridge 8. In the embodiment of the FIG. 1 is in a top care application application of the housing 5, a closure body 9 is inserted.

The care fabric cartridge 8 has, as shown FIG. 2 recognizable by a support body 10 which is formed according to the invention as a mandrel. On the mandrel 10 sits a care carrier 11, which is in the illustrated embodiment, a soaked with care fabric cylindrical felt body. The care substance is held in the care carrier 11 in liquid form. The care carrier 11 is formed so that a concentration distribution of the care substance held therein is effected by its capillary forces and thus a transport of care material towards the closure body 9 is given out when the care fabric cartridge 8 is inserted into the care fabric reservoir 6. The support body 10 passes through the care carrier 11 over its entire length. On the front side, the cylindrical care carrier 11 is on the one hand by a molded onto the support body 10 flange 12, to which in turn a handle 13 is formed, and on the other hand by a further flange 14 which is placed on the free end of the support body 10 and connected thereto before Deformations in the longitudinal direction of the support body 10, especially when inserting the same in the care fabric reservoir 6 protected. The support body 10 with its flange 12 and the handle 13 is as well as the disc formed as a flange 14 is a plastic part.

FIG. 3 shows in a longitudinal section, the care fabric cartridge 8. Dashed lines are in FIG. 3 possible developments shown. These are on the one hand to a locking extension 15 as an extension of the running as a mandrel carrying body 10. At the locking extension 15 is a locking cam 16 protruding formed in the radial direction. The care fabric reservoir 6 or the housing 5 of the care applicator 4 is associated with a complementary complementary complementary locking element receptacle, which has an insertion portion for insertion of the locking cam 16 and a locking portion behind which the locking cam 16 engages, if this after insertion thereof in the insertion has been rotated by a certain angle. Thus, the locking extension 15 is executed with its locking cam 16 and the complementary locking element of the housing 5 in the manner of a plug-in rotary locking (bayonet lock). According to another embodiment, a locking cam 16.1 is integrally formed on the flange 12. This is in the same way as this is described to the locking cam 16, with a complementary locking element receptacle on the front end side of the housing 5 for locking the care fabric cartridge on the housing 5 into engagement.

In the illustrated embodiment, it is provided that the inner diameter of the care fabric reservoir 6 is slightly smaller than the outer diameter of the Pflegestoffträgers 11 of the care fabric cartridge 8. This ensures that, as in FIG. 4 recognizable, the outer surface of the care carrier 11 is in contact with the closure body 9.

Nursing material is applied to a strand of hair in this embodiment in that the hair strand is pulled past the application substance applicator 4 in a contacting manner on the application surface 17 formed by the upper side of the closure body 9.

The above-described embodiment has been described with reference to two, arranged adjacent to the hair shaping surfaces Pfleggestoffapplikatoren. It is understood that a hair styling device can only be equipped with a care applicator. In the case of a straightener, this would be on one or the other long side of one of his arms.

FIG. 5 shows a not according to the invention hair styling device 1.1, of which also only the lower arm 2.2 is shown. The hair styling device 1.1 is constructed as that of the embodiment of FIGS. 1 to 4 The hair styling device 1.1 differs from the hair styling device 1 by the design of its care applicators 4.2, 4.3. The care applicators 4.2, 4.3 are identical. The following describes the care applicator 4.2. The housing 5.1 of the care substance applicator 4.2 has a care substance application outlet 18 designed in the manner of one of the longitudinal extensions of the housing 5.1. The care substance reservoir 6.1 has a rectangular cross-sectional geometry in this embodiment. Is used in this embodiment in the care fabric reservoir 6.1 a care fabric cartridge 8.1, which also has a support body 10.1 and a Pflegestoffträger 11.1. In the presentation of the FIG. 5 the care fabric cartridge 8.1 is shown in the manner of an exploded view. The support body 10.1 is U-shaped in cross-section and serves to receive the lower portion of the cuboid carried Pflegestoffträgers 11.1. This is held jammed with its lower portion within the U-shaped receptacle of the support body 10.1. Formed on the support body 10.1 is a handle 13.1 for handling the care fabric cartridge 8.1. The narrow side forming transverse side of Pflegestoffträgers 11.1 is slightly larger than the corresponding width of Pflegestoffreservoirs 6.1. This ensures that the care carrier 11.1 rests against the relevant inner walls of the care fabric reservoir 6.1 under a slight bias.

In this example, the care application application exit 18 is open. Moreover, the care fabric applicators 4, 4.1 are connected to the arm 2.2 of the hair styling device 1.1 such that the care carrier 11.1 is likewise heated by the heating element integrated therein. Heating of the care carrier 11.1 is provided at a temperature below its evaporation temperature, for example 15 ° to 30 ° below the same. In this example, care material is applied to the hair to be conditioned in vapor form. For this purpose, the heat radiated from the shaped warm hair into the care substance application outlet 18 is utilized by the heat at the top of the care substance carrier 11.1 is maintained above its vaporization temperature and care agent exits in vapor form from the care application application outlet 18 and passes in this way to the strand of hair guided past it.

FIG. 7 shows in a schematic cross-sectional representation of another, non-inventive embodiment of a designed as Straightener hair styling device 1.2. The hair styling device 1.2, like the hair styling devices already described in the preceding figures, has a care applicator 4.4. The care applicator 4.4 comprises a care fabric reservoir 6.2, which below the outer, curved shell 19 of the in FIG. 7 shown Armes 20 of Straighteners 1.2 is arranged. The care fabric reservoir 6.2 is connected via openings 21 with the environment. The openings 21 represent the care substance outlet. The openings 21 are distributed over the transverse extent of the care substance reservoir 6.2. In the illustrated example, the openings 21 of the longitudinal extent of the arm 20 and thus the longitudinal extension of the care fabric reservoir 6.2 form the following slots. In an alternative embodiment, it is provided that in the shell 19 round perforations, arranged in the manner of a grid are introduced as Pflegestoffaustritt.

Inserted into the care fabric reservoir 6.2 is a care fabric cartridge 8.2, which, like this, is the case in the process described example, which fills the care fabric reservoir 6.2. The care fabric cartridge comprises a lower-side support body 10.2. On this sits the care carrier 11.1. The support body 10.2 extends over the entire length of the care carrier 11.2. Formed on the support body 10.2 is a front side of the arm 20 of the hair styling device 1.2 led out handling strap, with the care fabric cartridge 8.2 can be inserted into the care fabric reservoir 6.2 and pulled out again after use. In a further development of in FIG. 7 shown embodiment of the hair styling device 1.2 is provided that extends the care fabric reservoir more or less completely along the inside outer shell of the respective arm of the hair styling device. The as a care release then serving openings also extend correspondingly wide. The care fabric cartridge to be used herein is then adapted to the geometry of the care fabric reservoir, which is constructed in principle like the care fabric cartridge 8.2.

The concept described with reference to the embodiment of the hair styling device with a care applicator is simple in construction and, above all, in the handling. The care cartons can be easily handled and stored, even if they are only partially used. This allows a problem-free change of the cartridge to be used in a care fabric reservoir, depending on the care substance to be applied in each case. In a hair styling device, such as described in the embodiment, with two care applicators different care ingredients can be applied, should this be desired.

For characterizing the care substance cartridges with regard to the care substance stored therein, they may be color-coded in their entirety or only with respect to the support body or the handle formed thereon and / or with regard to the care substance carrier. This allows an optical identification of the respective care substance in a care fabric reservoir.

The care substance cartridges described can basically be reused. To refill such a care fabric cartridge, that is, for re-impregnation of Pflegestoffträgers this can be inserted or suspended in a corresponding storage vessel until the care carrier has fully sucked with the care fabric.

The invention has been described with reference to an embodiment. Without departing from the scope of the applicable claims, numerous further embodiments for a person skilled in the art will be able to realize the invention without these having to be explained in greater detail in the context of these statements.
