By the present invention, it will be appreciated that the two-component hair dye can be mixed in situ and sent out in any direction at any moment during hair dyeing.

Preferably, the first container is at least partially made of a transparent and / or elastically deformable plastic material.

The first container may comprise a reservoir and an orifice in fluid communication with the reservoir, which orifice serves as an inlet for the first second raw material and thereafter serves as an outlet for the flow composition, in effect a second raw material. Is added to the first raw material by pouring accordingly.

Preferably, the reservoir comprises an inner deformable layer separate from the outer deformable layer of the first container. It may be possible for the inner temporary contact layer to gradually peel off from the outer variable layer by peeling. However, preferably, the inner temporary contact layer is composed of a flexible bag.

The orifice may extend through an insert that fits into the neck of the container, and the insert may have an annular passageway surrounding the tubular member that forms the orifice, the annular passageway between the inner and outer deformable layers. In gas communication with the buffer zone.

If the tubular member extends past the neck of the first vessel and into the reservoir of the first vessel, the portion of the tubular member in the reservoir may be formed of a support tube that is secured to the insert and whose cross section is open. Provide a passage that is at least partially rigid, and the flow composition passes through the rigid passage while the flexible bag collapses.

In order to suppress the flexible bag during mixing the first and second raw materials by shaking, the free end of the support tube away from the insert is close to the free end of the flexible bag away from the neck of the first container, The support tube has a sufficient length.

The insert may be interference fit with the neck of the first container and the removable plug may seal-close the orifice of the insert until the second container is in fluid communication with the first container.

Preferably, the applicator is secured to the first container such that the flow composition is easily released from the first container, the applicator being inflow of air into and out of the inner temporary layer and in and out of the first temporary layer. And a valve member having a single configuration operative to control the discharge of the flow composition from the one vessel.

The outlet of the valve member may be composed of a quadrolobe valve, the inlet of the valve member may be composed of a flapper valve, and the flapper valve may have an annular shape surrounding the four leaf valve. Can be.

If the applicator is an outlet tube with an elongated single passage through the flow composition, the four-lobed valve can be push fit into an elongated passage in the outlet tube, and the outlet tube itself can be directly or indirectly inserted into the first vessel (insert May be pressurized).

Also preferably, an applicator of foam or sponge material having an elastically compressed porous structure for delivering the flow composition is provided, which is provided at one end of a carrier that is detachably press-fitted onto the discharge pipe. It may also be provided in the form of a pad at or near it.

To facilitate targeting of a particular area, the pad may extend only in a portion around the circumference of the carrier.

Preferably, an applicator is provided with a plurality of elongate branch members protruding from the support, the flow composition is sent through the housing to this branch member, and the housing can be mounted above the discharge pipe and detachably attached to the first container. It may be fixed.

Such a housing may have a guide tube for receiving the free end of the discharge tube when mounted on top of the discharge tube.

It is also possible to configure the elongate branching member with a flexible filament such as a brush-shaped structure, but it is preferable to configure each of the elongate branching members in the form of a rigid comb of a comb-shaped structure.

For ease of manufacture, comb teeth may also be arranged in at least one row, especially when molded from plastics materials. When viewed from the end of one or more rows, it may, but need not, have a generally triangular appearance with different transverse sizes. In order to facilitate continuous dispersion, the flow composition may be sent out from the comb teeth, and each free end of the comb teeth may have at least one outlet.

The elongate branching member and the support can be removably removed from the housing. Accordingly, multiple supports can be provided, the user can select one of them, and the elongate branch members of the different supports can have different shapes. For example, comb supports with rigid combs can be replaced with brushed supports with flexible filaments.

The elongate branching member and the support are formed as a unit which can be fixed to the housing by fastening means comprising a catch. The hook portion can be elastically deformed and bound to an opening extending through the housing so that the hook portion can be separated away from the elongated branch member. It may be provided with an additional hook that acts as a pivot. Resilient bendable hooks shall be removable by finger force. However, simply pressing the housing against a hard surface allows the hook portion to be elastically bent to be separated, thereby separating the elongated branching member and support from the housing.

In order to facilitate assembly and robustness, the housing may be detachably screwed to the first container, and both the housing and the first container may snap to each other when completely screwed to secure the housing and the first container to a predetermined position. And lug means for aligning each other.

Flow compositions may be applied to the user's hair or scalp, wherein the first and second raw materials consist of hair dye compositions of different ingredients. In addition, multiple second containers may be used, one of which may be selected by the user, and each of the second containers may contain a different concentration of hair colorant.

As an embodiment, the delivery device according to the present invention will be described in detail below with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings illustrate hair dye kits that realize various aspects of the invention, and various aspects of the invention which are intended to be protected by the present application and other patent applications filed at the same time are various for use in delivering fluid compositions. It relates to an applicator, a coating device, and a delivery device.

While it is preferred that the flow composition is a hair dye composition, aspects of the present invention are not limited to such specific flow compositions. Examples of other flow compositions include drugs for pets, food compositions such as cake compositions, and the like, laundry fluids for clothing or carpets, cosmetics such as body lotions or moisturizers, adhesives or lubricants, and the like.

Problems may arise when using hair dye compositions.

One problem is that it may be necessary to produce a hair dye composition from two or more compositions immediately before use. This means that each composition needs to be stored separately so that the user can mix the compositions if necessary. Typically, one of the compositions is hydrogen peroxide and the other is a dye. On the other hand, the user should not be exposed to the risk of being soiled when adding the dye to hydrogen peroxide.

Another problem is that the applicator needs to be inclined at an angle to apply the hair dye composition to the hair. If supplied from a simple extrusion vessel to the applicator, the applicator can be used at any angle when the extrusion container is filled. However, as the extrusion container gradually empties, the applicator cannot be used immediately from all angles and requires work to first offset the infiltration of the hair dye composition. As a result, it is difficult to control the application of the hair dye composition, and in particular, it is difficult to apply to the hair boundary without contaminating the skin.

The hair dye kit of the present invention can provide a hair dye composition just before use, as well as an applicator to which the hair dye composition is supplied by a feeding device controlled by a user, in which the feeding device is located at any position. The hair dye composition is discharged by using a mechanically generated pressure difference (not an aerosol) so that the hair dye composition is always discharged even if it is at.

Delivery in all directions is possible until the prepared hair dye composition is discharged to 90% to 95%.

The hair dye kit also allows the user to control the amount and deliver the hair dye composition uniformly to a specific area while less soiling around the applicator.

No matter how careful the operation, there is no applicator capable of applying the hair dye composition to the hair root portion, the body of the hair and the boundary line as in the present application. Accordingly, there are provided various kinds of applicators selected from borderline applicators, surface applicators, and brush / comb applicators. The borderline applicator can be an outlet tube with a single outlet, and the surface applicator can be made of a porous material with multiple outlets. The brush / comb applicator may have a plurality of outlets for dispensing the hair dye composition, wherein the distributed hair dye composition is dispersed by a plurality of elongated branch members. As can be expected, the elongate branch member may be similar to the bristles of the bristles or combs of the brush. All various types of applicators are in fluid communication with the container for the hair dye composition.

Specific advantages of the hair dye kit of the present invention are as follows:

(a) only one selected from three different types of applicators is exposed during use, so there is no risk of hair being soiled by hair dye compositions remaining in or on other applicators not used during operation;

(b) Of the three different types of applicators, the surface applicator is formed of a foam or sponge having an elastically compressible porous structure, thereby improving the spread of the hair dye composition.

(c) Of the three different types of applicators, the brush / comb applicator has two or more outlets formed in each of its elongated branching members, so that the hair dye composition can be better dispersed.

Other advantages of the hair dye kit of the present invention are that the integral valve performs both functions of regulating air inlet and discharge of the hair dye composition simultaneously, and the support for the elongate branch member is separated at a position spaced apart from the hair dye composition. Being secured to the housing by one or more hooks, which may be possible, and that the brush / comb applicator can be positioned on the border applicator with the border applicator directly attached to the container.

Before explaining the surface applicator with reference to Figs. 7 and 8 and the brush / comb applicator with reference to Figs. 9 to 12, the delivery apparatus that cooperates with the borderline applicator will be described with reference to Figs. .

The bottle 10 is generally formed as a hollow body 12 having an elliptical cross section, the lower end of which is closed and an open neck 14 provided at the upper end. The neck portion 14 is formed with an outer threaded portion 16. The neck 14 is also provided with a pair of opposing lug means 18, only one of which is shown in FIG. 1. Each lug means 18 preferably comprises a gap 20 leading to the lamp 22.

At least the body 12 can be formed of an elastically deformable plastic material so that the shape of the bottle 10 can be quickly restored after being pressed. Such plastic material may be low density polyethylene, linear low density polyethylene (LLDPE) or polyethylene, and may be transparent. Although not transparent, the plastic material is preferably translucent and may or may not be colored.

The flexible bladder 24 may be formed by overlapping two sheets 26 of the same shape, with the upper opening 28 and the lower V-shaped edge 30 sealed together with most of the periphery of the sheets. To form a side-sealed bag having a. The bag 24 forms a reservoir for the first raw material, such as hydrogen peroxide, so that the bag should have good moisture barrier properties. Each sheet 26 may be a metallized sheet material and preferably comprises three layers of LLDPE sealant / adhesive / metallized PET (polyethylterphalate).

The pocket 24 is inserted into the bottle 10 through the neck 14 to form a container, which consists of an outer variable layer (body 12) and an inner contact layer (sheet 26) and The two layers are separated from each other by the buffer zone 32 as shown in FIG.

4, the support tube 34 can be inserted into the pocket 24 through the opening 28. The tube 34 may include a plurality of holes 36 formed over its length to provide an at least partially rigid passageway with an open cross section. The lower end 38 of the tube 34 may be open or closed. The lower end 38 of the tube 34 may be in contact with the bag 24 or without contacting the V-shaped edge 30 of the bag 24. The upper end of the tube 34 may be fixed to the insert 40 by any suitable method or means, or may simply be press-fitted into the insert 40.

The insert 40 may be partially inserted into the pocket 24 through the opening 28 and may also be partially inserted into the bottle 10 through the neck 14. Preferably, the insert 40 is permanently fixed around the opening 28 of the sheet 26 by means of heat welding, ultrasonic welding, or the like. Alternatively, the insert 40 and the pocket 24 may be integrally formed. It is desirable to secure the insert 40 inseparably from the neck 14 by a simple press fit method or other suitable method or means, but instead it may be exchanged to allow the user to detach.

As shown in FIGS. 2, 4 and 6, the insert 40 can be an integral plastic molded article having a tubular member 42, wherein the tubular member 42 forms an orifice and the side wall 44. ), Through the center of the transverse wall 46 and a pair of opposing bottoms 48.

The side wall 44 is provided at an upper end of the side wall to limit the insertion of the insert 40 into the bottle 10 and to extend outwardly, and approximately between the flange 50 and the transverse wall 46. An inward rib 52 located at an intermediate point. The transverse wall 46 has a plurality of holes 54, and an annular passageway 56 and a buffer region 32 formed between the tubular member 42 and the side wall 44 to surround the tubular member 42. It is connected through the hole 54. The lower portions 48 opposed to each other are formed in a hollow state to prevent shrinkage during manufacture, thereby making it easy to insert the insert 40 into the pouch 24 in a liquid tight state.

The lower end of the tubular member 42 may be recessed inward to accommodate the upper end of the tube 34, and the upper end of the tubular member 42 may be chamfered inward.

Typically, the bag 24 is supplied to the user in a state partially filled with a first raw material such as hydrogen peroxide. Therefore, it is necessary to prevent the first raw material from flowing out through the tube 34 and the tubular member 42. A detachable flip top stopper may be used to close the top of the tubular member 42. Alternatively, the top of the tubular member 42 may be closed with a breakable film seal. However, it is desirable to have a detachable cap 58 as shown in FIG.

The stopper 58, which can be made of an integral plastic molded article, can be provided with a plug seal 60 for sealingly closing the upper end of the tubular member 42. The fixing part 62 of the stopper 58 may be fitted in the airtight state to the neck 14 of the bottle 10. However, it is preferable to form the fixing portion 62 of the plug 58 so that it can be fitted in the air leakage state. For example, the outer threaded portion 16 formed on the neck 14 of the bottle 10 and the inner threaded portion 64 that are breathable screwed together may be formed to allow air to pass through the annular passage 56 for a long time.

One of the advantages of such a configuration is that in the case where the hydrogen peroxide in the pocket 24 becomes unstable to generate oxygen, air in the buffer zone 32 causes holes 54 and threads 16 and 64 of the insert 40. By discharging through), bag 24 can expand.

Another advantage of such a configuration is that, in the event of an unexpected pressure change in the buffer zone 32 due to air movement or the like, air is discharged back from the buffer zone 32 or back to the buffer zone 32 along the above-described path. It can be introduced.

The hair dye kit described above allows the user to prepare a hair dye composition or other flow composition just prior to use.

In practice, at least a second raw material is added to the first raw material in the reservoir. If the reservoir is supplied empty or previously empty, the reservoir will of course have to be filled with a predetermined amount of the first raw material first. In any case, it is necessary to mix the raw materials that were originally separated.

As schematically shown in FIG. 4, the second raw material may be stored in a completely separate container 66. If the first raw material is hydrogen peroxide, the second raw material will be a dye. Since the dye may be sensitive to oxygen, the container 66 needs to have full oxygen barrier properties. In addition, if the dye is in the form of a gel, cream, or paste, the container 66 should be plastically deformable to allow the user to squeeze out the dye. On the other hand, if the dye is in liquid form, it may be discharged from the container 66 by gravity.

If the container 66 is elastically deformed, the bag 24 is preferably expanded with air over the first raw material, and if the container is inelastically deformed, the bag 24 is preferably flat.

The user may be supplied with a number of containers 66, each container 66 will contain different materials, such as hair dyes of different concentrations, and intentionally pouring one or more containers 66 into the reservoir. Pour may also form a special flow composition, such as a special concentration of hair dye composition.

It is preferred that the vessel 66 or each of the vessels include an elongated nozzle 68 that extends through the tubular member 42 and into the tube 34. By such a configuration, even when the user squeezes the container 66 with both hands, it is possible to achieve a good coupling that the container 66 rarely falls off the bottle 10. In addition, due to the configuration, the contents of the container 66 are ejected directly near the contents of the bag 24 to obtain a good mixing effect. The vessel 66 must be opened before the elongated nozzle 68 is inserted into the tubular member 42, which opening is ruptured, incised or torsionally removed from the nozzle tip 70 (shown in broken lines in FIG. 4). Can be done.

As the second raw material moves from the container 66 to the bag 24, the volume of air above the first raw material in the bag 24 will gradually decrease and the compressed air must be discharged so that the bag 24 expands. It will be appreciated that they should be prevented.

If the nozzle 68 is loosely fitted to the tubular member 42, the compressed air will be discharged through the loose coupling. Alternatively, one or more splines may be formed along the length of the nozzle 68, or one or more air vents may be formed in the dye container proximate to the base of the nozzle 68. Depending on the nature and capacity of the second raw material in the container 66, the compressed air will move upward through the second raw material to form an air pocket in the container 66, the air pocket having a pocket 24. Will expand as the air pocket in the pan is contracted.

Even when the pocket 24 is inflated, air in the buffer zone 32 will be discharged through the apertures 54 formed in the transverse wall 46 of the insert 40, as described above.

After adding a sufficient amount of the second raw material to the first raw material, the container 66 will be removed from the bottle 10 and the container will be stored closed or resealed for later use.

Instead of pouring and adding the second raw material according to the first raw material, the second raw material may be accommodated in the bag 24 or in a container formed therein, the container holding the body 12 of the bottle 10. The second raw material may be added to the first raw material by being broken by a method such as weaving, or by another suitable method.

When the second raw material is added to the first raw material, it is preferable to shake the bottle 10 to mix the two materials. The user shakes the upper end of the tubular member 42 with a gloved hand to prevent the contents of the bag 24 from leaking out. However, it would be more convenient for the user to cover the stopper 58 again so that the plug seal 60 closes the top of the tubular member 42. In any case, the tube 34 inhibits the movement of the bag 24 during the shaking or flipping of the bottle 10, thereby facilitating mixing by allowing the contents in the bag 24 to move more freely than the bag 24. Shaking and mixing will be best when about 10% of the volume of the pocket 24 is empty into the space. If both the bag 24 and the body 12 of the bottle 10 are translucent, you will be able to visually confirm that mixing is complete.

In order to discharge the flow composition composed of the first and second raw materials, in particular the hair dye composition composed of hydrogen peroxide and dye, as shown in Figs. 5 and 6, the insert 40 is exposed and the insert 40 is exposed. The discharge pipe 72 can be attached to it.

The discharge tube 72 may be made of an integral plastic molded article, the discharge tube including a cylindrical portion 74 connected to the domed portion 76, which in turn is connected to the inclined portion 78. The bottom end of the cylindrical portion 74 is formed with a rib 80 facing outward. The upper end of the cylindrical portion 74 is formed adjacent to a shoulder formed by the domed portion 76. One or more (eg, three) air inlets 84 passing through the domed portion 76 may be formed equally spaced apart from each other along the circumferential direction of the domed portion 76. An elongated passage 86 is formed in the inclined portion 78, which becomes narrower along the length direction from the lower end to the single outlet 88 of the upper end. An annular depression 90 is formed on the inner side of the inclined portion 78 near the wide lower end of the passage 86. Proximate to the narrow upper end of the passage 86, an annular rib 92 is formed on the outer surface of the inclined portion 78.

A silicone member may be used to attach the valve member 94 to the discharge pipe 72, which may be formed as a single piece.

Preferably, the valve member 94 includes an inlet in the form of an annular flapper valve 96 that acts as a one-way check valve that regulates the inflow of air through the air inlet 84.

Preferably, the valve member 94 includes an outlet in the form of a central four-lobed valve 98 that acts as a one-way check valve that regulates the outflow of the hair dye composition through the passage 86. The four lobe valve 98 is open from the center rather than from the side to allow for a smooth flow of the hair dye composition. However, instead of this four-lobed valve 98, the discharge portion of the valve member 94 may be configured as a flapper valve, an umbrella valve or a duckbill valve.

The flapper valve 96 and the four leaf valve 98 have an intermediate portion comprising a frusto-conical positioning wall 102 and a transverse sealing wall 100 with annular ribs 104 on the outer side. Are bonded to each other by

By pressing the four-lob valve 98 into the passage 86 until the annular rib 104 of the valve member 94 is engaged with the annular depression 90 of the discharge pipe 72, the valve member 94 is discharged. Can be easily attached to 72.

Then, the cylindrical portion of the discharge pipe 72 until the rib 80 of the cylindrical portion 74 is snapped to the rib 52 of the insert 40 (which can be sensed by hearing or at least tactilely). 74 is pressurized into the annular passageway 56 of the insert 40, so that the discharge pipe 72 can be easily attached to the insert 40. In the snap coupling, the shoulder 82 of the discharge pipe 72 is In contact with the shoulder 50 of the insert 40 and the sealing wall 100 of the valve member 94 is sealingly engaged with the upper end of the tubular member 42 of the insert 40.

As another configuration, the discharge pipe 72 may be attached to the insert 40 by using a screw connection instead of the pressure coupling.

The flow pipe 72 may be attached to the insert 40 and then shaken to mix or remix the flow composition.

In order to discharge the hair dyeing composition from the bag 24 to the outlet 88 of the discharge pipe 72 and to discharge the hair dye straight from the outlet 88 to the root of the hair or the like, the user may open the main body 12 of the bottle 10. Squeeze As a result, the air in the buffer region 32 is compressed, but since the flapper valve 96 closes the air inlet 84, the compressed air is provided with a hole 54, an annular passage 56, and an air inlet ( 84) does not exit through the fluid passageway. Instead, the compressed air partially compresses the sac 24, thereby including a fluid comprising a tube 34, a tubular member 42, a truncated conical positioning wall 102, and an open four-lobed valve 98. Some hair dye compositions exit through the passageway. When the user stops squeezing the main body 12 of the bottle 10, the shape of the bottle 10 is quickly restored, and the buffer area 32 is expanded. The four lobe valve 98 is closed to prevent the hair dye composition from being sucked back behind the four lobe valve 98 and the pouch 24 remains in a partially compressed (collapsed) state. Instead, air is sucked into the buffer zone 32 through a flapper valve 96 that is open for inflow of air through the air inlet 84.

The user repeats squeezing the main body 12 of the bottle 10 at an appropriate pressure and the number of times according to the situation.

When the pocket 24 collapses gradually and the sheets 26 of the pocket 24 come into contact with each other, the hole 36 in the tube 34 prevents the hair dye composition from remaining and the tube 34 The tube 34 itself may collapse in order to drain the flow composition in the cavities.

As the hair dye composition is dispensed, the user can see the pocket 24 collapse through the body 12 which is at least translucent. Thus, the user can know the extent to which the hair dye composition is consumed.

As described above, the side seal envelope is used as the first raw material storage, but the storage may be formed in other forms. For example, using an inverting-half-bag bottle, a delaminating bottle gradually peeling away from its neck, or a compression blown bag integrally formed with the insert, etc. An inner contiguous layer separate from the variable layer may be provided.

In addition, as described above, the valve member has an integral structure and performs two functions, but other types of valve members such as, for example, independent valves for controlling the discharge of the hair dye composition and the inflow of air may be used. In this case, the air inlet control valve may be a simple air hole formed in the body of the bottle that the user can block with a finger.

7 and 8, the surface applicator 106 is detachably fixed to the discharge port 88 of the discharge pipe 72. In particular, the surface applicator 106 may include a pad 108 formed of a foam or sponge material having an elastically compressible porous structure. Such a structure not only has a plurality of outlets, but also allows for the careful manipulation of the hair dye composition which exits the outlet 88 and passes through the pad 108, evenly along the hair boundary. . The pad 108 is located at or near the top of the carrier 110, and the lower half of the carrier 110 is frustoconical in shape with a wider cross section. On the inner side of the lower half of the carrier 110, an annular depression 112 is formed which detachably engages with the annular rib 92 of the discharge tube 72 when the carrier 110 is pressed into the discharge tube 72. . The carrier 110 and the discharge pipe 72 may be configured to not rotate relative to each other. The surface of the pad 108 may be formed into a curved surface to facilitate accurate application, with the curved surface extending only in a portion around the upper half of the carrier 110. If the pad 108 is formed of a plastic material and the carrier 110 is also formed of a plastic material, the pad 108 may be fixed to the carrier 110 using an adhesive. If the original surface applicator 106 was not cleaned and reused, multiple surface applicators 106 would be provided. These multiple surface applicators will be identical to one another if they are disposable, and will be different from one another for replacement.

As shown in FIGS. 9-12, instead of the surface applicator 106, the brush / comb applicator 114 may be detachably fixed on the outlet 88 of the discharge pipe 72. Brush / comb applicator 114 includes a housing 116 and a detachable unit 118.

The brush / comb applicator 114 may be secured to the neck 14 by screws or snaps.

The housing 116 is an integral plastic molded article, and from the top, the inclined open chamber 122 having the opening 120 and the grooved series of webs 124 on both side walls, the chamber 128 and the chamber ( A guide tube 126 for communicating 122, a slot 130 formed at the upper end of the chamber 128, an inner threaded portion 132 formed near the lower end of the chamber 128, and a lower end of the chamber 128. It is formed by a pair of opposing lug means 134 located.

The inner threaded portion 132 is preferably able to escape from the mold without rotation.

By coupling the threaded portion 132 inside the chamber 128 to the outer threaded portion 16 of the neck 14, the housing 116 can be detachably screwed to the bottle 10. As the housing 116 is gradually screwed in, the outlet 88 of the outlet tube 72 is inserted into the guide tube 126. As a result, the lug means 134 snaps over the ramp 22 of the lug means 18 and snaps into the gap 20 of the lug means 18. Such snapping indicates audible or at least tactilely that the housing 116 is fully screwed into the bottle 10. In this final position where the lug means 18 and the lug means 134 are engaged with each other, the chamber 122 is opened in the main axial direction of the body 12, usually having an elliptical cross section.

The detachable unit 118, which is the last component of the hair dyeing kit, may also be formed from an integrally molded article made of plastic, such as polypropylene, with silicon or the like added to reduce the coefficient of friction.

At least a portion of the detachable unit 118 may be translucent so as to indicate to the user the delivery of the flow composition.

Unit 118 includes a support 136 that is progressively inclined and generally flat from the narrow top to the wide bottom. The narrow upper end includes an elastic hook portion 138 having an annular tip 138a. The wide bottom end comprises a rigid hook 140 with an annular tip 140a. An edge 142, which is a complementary outline of the opening of the chamber 122, is formed around the support 136. A number of elongated branch members, such as rigid comb 144, protrude from support 136 in the opposite direction of elastic hanger 138, rigid hanger 140, and rim 142. A plurality of outlets 146 through which the flow composition exits is formed through the support 136.

As shown in detail in FIG. 9, comb teeth 144 may be arranged in two rows. The comb teeth 144 may have a generally triangular shape that differs in lateral size when viewed at both ends of the two rows, but it is not necessary. The transverse size of the comb 144 may increase gradually from the narrow upper end of the support 136 to the wide lower end of the support 136. In addition, the comb teeth 144 in different rows may be staggered with respect to each other and may have a generally triangular shape with a similar thickness when viewed from the two rows.

As best shown in FIG. 11, at least two (or all possible) outlets 146 extend through each comb 144. However, it may be desirable that one or more outlets 146 do not extend through comb 144. For example, one or more outlets 146 may be located on the support 136 between adjacent comb teeth 144. At least two (or all possible) outlets 146 extending through the comb 144 may be opened through the orifice 148 at the free end of the comb 144.

For convenience, the orifice 148 is described as being located at the free end of the comb 144, but is substantially formed slightly behind the free end of the comb 144, in part to prevent it from being applied directly to the scalp. It is also partly due to the result of a preferred molding technique known as a passing face shut off technique that can form the orifice 148 in a simple two-part mold without using side pins.

In order to assemble the unit 118 with the housing 116, the annular tip 140a of the rigid hanger 140 need only be positioned in the slot 130 and pivoted. In this way, the free edge of the edge portion 142 is engaged with the grooved web 124, and the annular tip portion 138a of the hook portion 138 is deformed so that the hook portion 138 opens in the opening 120. Is inserted. When the annular tip 138a of the hook portion 138 exits the opening 120 and snaps to a portion of the housing 116 around the opening 120, the unit 118 is fully secured to the housing 116. do.

The order for separating the unit 118 from the housing 116 is as follows. The hook portion 138 is separated by finger pressure. Alternatively, the hook portion 138 may be released by pressing the housing 116 against a hard surface to retract the annular tip 138a of the hook portion 138 into the opening 120. It will be appreciated that when the hook portion 138 is removed, the orifice 148 is separated.

One reason for separating unit 118 from housing 116 is to facilitate cleaning of residual hair dye composition.

Another reason for separating unit 118 from housing 116 is to replace it with another type of unit 118. For example, a rigid comb 144 providing a comb-like structure may be a brush-like or sponge-like structure with a plurality of flexible bristles, orifices having different sizes and / or shapes and / or Or it may be desirable to be able to replace with a comb-like structure. By doing so, it will be easy to disperse the ejected hair dye composition according to a variety of different situations in which the hair length, hair form and the like differ.

Depending on the flow characteristics of the hair dyeing composition or the need for various dyeings such as hair root dyeing, bleaching, or accentuation, the size, position and shape of the orifice 148 of each unit 118 can be modified.

In this specification, the 1st container which accommodates a 1st raw material can be interpreted as including the bottle in which one applicator or the combination of several applicators is mounted.

Also in the present specification, the flow composition may exhibit pseudo-plastic flow characteristics, wherein the pseudo-plastic flow characteristics are such that the viscosity of the flow composition decreases with shear, and once shear is stopped, This means that the viscosity increases until the internal structure (which determines the initial viscosity) is quickly reconstituted to approximate the initial viscosity.

The aforementioned pseudo-plastic flow properties of the flow composition should have a shear strain rate in the range of 0.01 / second to 10,000 / second, which range is most suitable when the flow composition is a hair dye composition.

For example, in a suitable flow composition, the viscosity measured at a shear strain of 2000 / second is at least 0.01 Pa.s (preferably at least 0.15 Pa.s) and the viscosity measured at 10 / second is 5 Pa. less than or equal to .s (preferably less than or equal to 1.4 Pa.s).
