Description

  The present invention relates to a dispenser.

  Conventionally, a two-component dispenser that stores fluid first agent and second agent constituting a hair cosmetic composition used for hair dyeing, decoloring, or destaining in respective housing portions, and merging them to discharge them It has been known. For example, a configuration has been proposed in which a discharge tool is fitted to a pair of aerosol cans arranged side by side, and a liquid contained in each aerosol can is discharged from the discharge tool (see Patent Document 1).

  Specifically, the two-component dispenser described in Patent Document 1 includes two aerosol cans and a discharge tool that connects the upper portions of the aerosol cans. The discharge tool includes a nozzle that communicates with each stem of each aerosol can. The inside of the nozzle is divided into left and right parts by a partition plate provided vertically in the middle part in the left-right direction. And the liquid in each aerosol can is discharged through a nozzle by depressing the pressing head of the discharge tool using the lever and pressing down each stem. At that time, since the inside of the nozzle is divided into left and right parts by a partition plate, the liquid discharged from each stem is discharged from the nozzle tip in a left and right two-layer structure.

Japanese Patent Laid-Open No. 11-334767

  By the way, the first agent and the second agent of the hair cosmetic composition have different properties. However, in consideration of such a difference in properties, it has not been conventionally studied to discharge the first agent in a state where it is difficult to be exposed to the outer surface.

  The present invention has been made in view of these problems, and an object of the present invention is to provide a technique for discharging a hair cosmetic composition in a state in which the first agent is hardly exposed on the outer surface.

  The dispenser of the present invention was accommodated in a plurality of accommodating portions for accommodating a plurality of fluid agents constituting a hair cosmetic composition used for hair dyeing, decoloring or decoloring, and a plurality of accommodating portions. And a discharge tool for discharging the agent together. The plurality of housing parts include a first housing part for housing the first agent of the hair cosmetic composition and a second housing part for housing the second agent of the hair cosmetic composition. . In addition, the discharge tool has a plurality of divisions for joining the agent stored in the plurality of storage portions in a laminated state of three or more layers including two outer layers and one or more inner layers sandwiched therebetween. A flow path is formed. Then, the agent is supplied from the housing portion to the divided flow path so that the first agent flows out of the divided flow path corresponding to the inner layer and does not flow out of the divided flow path corresponding to the outer layer.

  According to such a configuration, a plurality of agents constituting the hair cosmetic composition are joined together in a laminated state in which the first agent is not an outer layer. For example, when the plurality of agents are two types of the first agent and the second agent, the first agent and the second agent merge in a stacked state in which the first agent is sandwiched between the second agent. For this reason, the hair cosmetic composition discharged from the discharge tool is discharged in a state where the first agent is hardly exposed to the outer surface. Therefore, the hair cosmetic composition can be discharged in a state where the first agent is hardly exposed on the outer surface.

  By the way, as for the division | segmentation flow path, the flow-path exit has a flat shape and may be divided along the adjacent division | segmentation flow path and a flat plane. According to such a configuration, the exposure amount of the first agent in the stacked state can be reduced. Therefore, the effect of making it difficult to expose the first agent to the outer surface can be enhanced.

  Further, the discharge tool may be formed with N + 1 divided flow paths having a shape in which one flow path is divided into N + 1 layers by N partition plates (N is an integer of 2 or more). With such a configuration, the plurality of divided flow paths can be formed with a simple structure.

  In particular, when N is 2, the discharge tool is formed with three divided flow paths having a shape in which one flow path is divided into three layers by two partition plates. In this case, the agent accommodated in the plurality of accommodating portions merges in a three-layer laminated state including two outer layers and one inner layer sandwiched between them. Specifically, the first agent flows out from the divided flow path corresponding to the inner layer. For example, when the plurality of agents are two types of the first agent and the second agent, the first agent flows out from the divided flow channel corresponding to the inner layer, and the second agent flows out from the divided flow channel corresponding to the outer layer. The For this reason, the hair cosmetic composition can be discharged in a laminated state in which the first agent is least exposed. That is, for example, when two types of agents (first agent and second agent) are joined in a laminated state, in addition to a laminated state of three layers, a laminated state of five layers or seven layers is also possible. However, when the second agent is used in this way, the amount of the second agent serving as the outer layer is reduced as compared with the three-layer laminated state. For this reason, in terms of making it difficult to expose the first agent, it is preferable that the first agent is merged in a laminated state of three layers.

  Further, the divided flow path may have a shape in which a flow path having the same shape as the flow path after merging is divided by a partition plate. According to such a configuration, the shape of the agent flowing out from the divided flow path is easily maintained even in the flow path after joining, and the laminated state is not easily broken. Therefore, the exposure amount of the first agent can be reduced.

Embodiments to which the present invention is applied will be described below with reference to the drawings.
[First Embodiment]
As shown in FIGS. 1 to 8, the two-component dispenser 1 of the first embodiment includes a pair of hair dyes in which a first liquid (first agent) and a second liquid (second agent) are accommodated ( Two discharge containers A, and a discharge tool B for discharging the first liquid and the second liquid accommodated in the discharge container A together. The first liquid is a liquid having a high pH in which an alkaline agent (for example, ammonia or monoethanolamine) is blended. Moreover, the dye for hair dye is mix | blended with the 1st liquid. On the other hand, the second liquid is a liquid having a low pH and containing an oxidizing agent (for example, hydrogen peroxide). In general, the first agent of the hair cosmetic composition has a stronger irritation to the skin and a stronger irritating odor than the second agent. In addition, although ammonia is mentioned as a factor of the irritating odor of the 1st agent, it is not restricted to this, For example, when the 1st agent contains ammonium salt, it is the same.

  The discharge container A is a form in which the stem 11 protrudes from the upper surface of the body portion 10 so as to be able to be pushed in an upward biased state. In this example, as a pair of the first discharge container A1 and the second discharge container A2, Each adopts an aerosol can. Specifically, the first discharge container A1 and the second discharge container A2 can be pushed in from the upper surfaces of the first barrel portion 10a and the second barrel portion 10b in an upward biased state. 11b protrudes. In each discharge container A1, A2, the built-in discharge valve is opened by pushing down the stems 11a, 11b, the liquid is discharged through the stems 11a, 11b by the stored gas pressure, and the stems 11a, 11b are pushed down. When is released, a known mechanism is used in which the stems 11a and 11b are lifted by upward bias, the built-in discharge valve is closed, and the liquid discharge is stopped.

On the other hand, the discharge tool B includes a container fixing frame B1, a container fixing cylinder B2, a discharge head B3, and a pressing operation unit B4.
The container fixing frame B1 plays a role of fixing both of the first discharge container A1 and the second discharge container A2 arranged side by side on the outer periphery of the upper end.

  The container fixing cylinder B2 includes an outer peripheral wall 30 for fitting the lower part to the outer periphery of the first discharge container A1 and the second discharge container A2 arranged in parallel via the container fixing frame B1, An inner peripheral wall 32 is suspended through a flange-like top wall 31 extending in the direction, and is fastened to a pair of first discharge container A1 and second discharge container A2 that are juxtaposed with each other. ing. Further, the front and rear recesses 33 and 34 having the upper surface and the front and rear surfaces opened are recessed in the front portion and the rear portion, respectively, with the inner peripheral wall 32, the outer peripheral wall 30 and the flange-like top wall 31 being recessed downward. Has been established.

  As shown in FIGS. 1 to 7, the discharge head B <b> 3 has a nozzle 41 projecting from the front surface of a horizontally long oval cylindrical casing 40, and a pair of first stem fitting cylinders 42 and Two stem fitting cylinders 43 are respectively suspended, and a liquid guiding mechanism is provided therein.

  Specifically, as shown in FIGS. 3 to 5, the discharge head B <b> 3 extends a bottom wall 40 c opened via a pair of connecting hinges 44 to a casing body having a peripheral wall 40 a and a top wall 40 b. It is formed in a state, and is configured to fix the bottom wall 40c to the casing body by ultrasonic bonding during assembly.

  As shown in FIG. 8, the liquid guiding mechanism covers the first liquid and the second liquid contained in the discharge container A, covering the first liquid layer (inner layer) L1 and the upper and lower surfaces of the first liquid layer L1. And a second liquid layer (outer layer) L2 having the same lateral width, and a mechanism for joining and discharging from the nozzle 41 in a three-layer laminated state (cross-sectional pattern).

  The specific structure of the liquid guiding mechanism is as follows. That is, a partition wall 45 is provided in the center of the casing 40, and the casing 40 is divided into a first liquid dividing chamber 46 and a second liquid dividing chamber 47 in the left-right direction. In addition, two partition plates 48a and 48b are provided in the base end portion of the nozzle 41 in parallel with each other in the vertical direction, and the flow path of the base end portion of the nozzle 41 is divided into three flow paths in the vertical direction. It is divided. In the following description, these three divided channels are referred to as “upper divided channel”, “middle divided channel”, and “lower divided channel” in order from the top. The first through hole 49 communicates from the first liquid dividing chamber 46 to the middle dividing flow path (the dividing section at the center in the vertical direction in the nozzle 41), and the upper divided flow path and the lower divided from the second liquid dividing chamber 47. A second through hole 50a and a third through hole 50b communicating with the flow path (upper and lower divided sections in the nozzle 41) are formed. The partition wall 45 is formed integrally with the casing body, and is fitted into a fitting recess 51 whose lower end is recessed at a predetermined position of the bottom wall 40c.

  The pressing operation unit B4 includes a mounting frame unit 80 and a pressing plate 81. The mounting frame portion 80 is fitted to the inner surface of the inner peripheral wall 32 of the container fixing cylinder B2. The pressing plate 81 connects the front edge portion to the front edge of the mounting frame portion 80 via a hinge 82. The pressing plate 81 has a rear upper surface as a pressing portion, a pressing protrusion 83 projecting from the lower surface is in contact with the upper surface of the casing 40, and when the pressing portion is turned down around the hinge 82, the discharge head B3 is configured to be pushed down.

  When using the two-component dispenser 1 configured as described above, by pressing the pressing portion, the pressing plate 81 rotates about the hinge 82 to push down the discharge head B3, and the first discharge container The first stem 11a and the second stem 11b of A1 and the second discharge container A2 are pushed down, respectively. Thereby, the first liquid discharged from the first discharge container A1 through the first stem 11a is interposed between the partition plates 48a and 48b from the first liquid dividing chamber 46 through the first through hole 49. It is discharged into the formed middle divided flow path (the divided section at the center in the vertical direction). On the other hand, the second liquid discharged from the second discharge container A2 through the second stem 11b is separated from the second liquid dividing chamber 47 through the second and third through holes 50a and 50b. Are discharged into an upper divided flow path (upper divided section) formed above and a lower divided flow path (lower divided section) formed below the partition plate 48b. As a result, as shown in FIG. 8, from the tip of the nozzle 41, the first liquid layer L1 and three layers composed of the second liquid layer L2 having the same lateral width that covers the upper and lower surfaces of the first liquid layer L1. It is discharged in a discharge form having a cross-sectional pattern.

  As described above, according to the first embodiment, when the first liquid and the second liquid accommodated in each discharge container A1, A2 are discharged from the discharge tool B, the second liquid is interposed between the second liquids. The first liquid layer L1 is covered with two second liquid layers L2 from above and below. For this reason, the discharge liquid from the discharge tool B is discharged in a state in which the first liquid is hardly exposed to the outer surface. Therefore, the hair dye can be discharged in a state where the first agent is hardly exposed to the outer surface.

  As a result, for example, since the first liquid that is strongly irritating to the skin (scalp) is less likely to directly contact the skin, it is possible to suppress irritation to the skin. Further, for example, since the first liquid having a strong irritating odor is difficult to be exposed, the irritating odor of the discharged liquid can be suppressed. Further, for example, since the first liquid containing the dye is difficult to be exposed, it is possible to make it difficult to generate background stains. In addition, although these effects are an example of the effect by discharging a hair dye in the state in which a 1st agent is hard to expose to an outer surface, effects other than this may be sufficient.

  Further, in the present embodiment, the flow path cross section of the flow path at the tip of the nozzle 41 (the flow path in which the discharge port is opened) is shorter in the vertical direction (vertical direction) than in the horizontal direction (horizontal direction). It is a flat shape, and three divided flow paths are formed by further dividing such a flat shape in the vertical direction. For this reason, each divided flow path has a flat shape in which the vertical dimension is extremely shorter than the horizontal dimension, and is divided along the adjacent divided flow paths and the flat plane (upper and lower surfaces). Accordingly, the exposure amount of the first liquid in the stacked state (specifically, the exposure amount on the side surface of the stack) can be reduced. In addition, since the first agent and the second agent easily come into uniform contact with each other on the flat surface, it is possible to make it difficult for the mixture to be biased, thereby suppressing hair coloring unevenness.

  Moreover, since the divided flow path has a shape in which one flow path is divided into three layers by two partition plates 48a and 48b, it can be realized with a simple structure. In particular, since the first liquid is disposed on the innermost side in the laminated state, the discharge liquid can be discharged in the laminated state in which the first liquid is least exposed.

  In addition, the divided flow path has a shape in which the flow path having the same shape as the flow path after the merge is divided by the partition plates 48a and 48b. Therefore, the shapes of the first liquid and the second liquid flowing out from the divided flow path are It is easy to maintain the flow path after the merge, and the laminated state is not easily broken. Therefore, the effect of making it difficult to expose the first liquid can be enhanced.

  In the first embodiment, the two-liquid discharger 1 corresponds to an example of a discharger. In addition, the first discharge container A1 and the second discharge container A2 correspond to an example of a storage part, and in particular, the first discharge container A1 corresponds to an example of a first storage part, and the second discharge container A2 It corresponds to an example of a second housing part. Further, the discharge tool B corresponds to an example of the discharge tool, and the partition plates 48a and 48b correspond to an example of the partition plate.

[Second Embodiment]
FIGS. 9 to 11 show the second embodiment, and the configuration is basically the same as that of the first embodiment (FIG. 1 and the like) except for the ejection head B3. Therefore, the description is omitted. Further, the discharge head B3 is also fitted to the first stem fitting cylinder 42 fitted to the first stem 11a of the first discharge container A1 and the second stem 11b fitted to the second discharge container A2. The stem fitting cylinder 43 is suspended from the casing 40 and the nozzle 41 is provided on the front surface of the casing 40 in the same manner as in the example of FIG. 1, and the internal liquid guiding mechanism is different. Note that the third embodiment described below is the same in this respect, and therefore such description is omitted below.

  The liquid guiding mechanism in the present embodiment is provided with a partition wall 45a that longitudinally cuts the central portion in the casing 40 forward and backward. The partition wall 45a has a central vertical wall 52b erected from the other end edge of the first horizontal wall 53a extending from the upper end of the lower vertical wall 52a, and further a second horizontal wall 53b extended from the upper end of the central vertical wall 52b. The upper vertical wall 52c is erected from the other end edge of the first liquid dividing chamber 46, and the first liquid dividing chamber 46 and the second liquid dividing chamber 47 are divided into two in the left-right direction. In addition, the front end of the central space between the first horizontal wall 53a and the second horizontal wall 53b is connected to the middle divided flow path (vertical direction of the nozzle 41 base end through a through hole at the nozzle 41 base end opening position provided in the peripheral wall 40a. The lower space of the first horizontal wall 53a communicates with the lower divided flow path (the lower portion of the base end of the nozzle 41), and the upper space of the second horizontal wall 53b similarly divides into the upper portion. It communicates with the channel (upper base end of the nozzle 41).

  Therefore, the first liquid discharged from the first discharge container A1 is separated from the first liquid dividing chamber 46 through the central space between the first horizontal wall 53a and the second horizontal wall 53b (nozzle divided flow path (nozzle)). 41 at the center of the base end portion in the vertical direction). On the other hand, the second liquid discharged from the second discharge container A2 flows into the lower divided flow path (below the base end of the nozzle 41) from the second liquid dividing chamber 47 through the lower space of the first horizontal wall 53a. In addition to being discharged, it is discharged to the upper divided flow path (above the base end portion of the nozzle 41) through the space above the second horizontal wall 53b. As a result, similar to the first embodiment, from the tip of the nozzle 41, the first liquid layer L1 and the second liquid layer L2 having the same lateral width that covers the upper surface and the lower surface of the first liquid layer L1 3 It discharges with the discharge form provided with the cross-sectional pattern of the layer.

[Third Embodiment]
12 to 15 show a third embodiment. In this embodiment, the liquid guiding mechanism includes a first liquid supply chamber 55 in the center in the vertical direction and second and lower second liquid supply chambers 56a and 56b at the front end in the casing 40 behind the nozzle 41, and a partition wall 57 and a bottom. It is defined by the wall 40c. The first liquid supply chamber 55 and the second liquid supply chambers 56a and 56b each have a flat rectangular parallelepiped shape. Also, a partition wall 45b extending from the right rear end of the partition wall 57 to the rear wall 40a is provided so as to reach the peripheral wall 40a. It is divided into a dividing chamber 47 for use.

  The right side of the first liquid supply chamber 55 is open, and a communication hole is formed in the rear of the second liquid supply chambers 56a and 56b. The first liquid supply chamber 55 communicates with the second liquid dividing chamber 47 and the second liquid supply chambers 56a and 56b through the communication holes. In addition, the distal ends of the first liquid supply chamber 55 and the second liquid supply chambers 56a and 56b are connected to the middle divided flow path (the nozzle 41 base end through the through hole in the nozzle 41 base end opening position provided in the peripheral wall 40a. It communicates with the lower divided channel (lower part of the nozzle 41 base end) and the upper divided channel (upper part of the nozzle 41 base end), respectively.

  For this reason, the first liquid discharged from the first discharge container A1 flows from the first liquid dividing chamber 46 through the first liquid supply chamber 55 to the middle divided flow path (vertical direction of the base end portion of the nozzle 41). Discharged in the center). On the other hand, the second liquid discharged from the second discharge container A2 flows into the lower divided flow path (below the base end of the nozzle 41) from the second liquid dividing chamber 47 through the second liquid supply chambers 56a and 56b. And it discharges to an upper division channel (above the base end part of nozzle 41). As a result, similar to the first embodiment, from the tip of the nozzle 41, the first liquid layer L1 and the second liquid layer L2 having the same lateral width that covers the upper surface and the lower surface of the first liquid layer L1 3 It discharges with the discharge form provided with the cross-sectional pattern of the layer.

[Other Embodiments]
As mentioned above, although embodiment of this invention was described, it cannot be overemphasized that this invention can take a various form, without being limited to the said embodiment.

  (1) The first through hole 49, the second through hole 50a, and the third through hole 50b exemplified in the first embodiment are on the side close to the center of the flow path as in the first modification shown in FIG. The shape (arrow C) may be a shape in which the wall (surface) of the wall is obliquely widened. If it does in this way, the effect that the agent which passes a penetration hole will spread easily in a transverse direction will be acquired. Further, if the corner portion formed at the base end portion in the nozzle 41 is rounded (arrow R), an effect is obtained that the agent hardly remains at the corner portion (the residue is not easily generated). In addition, in FIG. 16, although the 2nd through-hole 50a is illustrated, the 3rd through-hole 50b is also the same. On the other hand, the first through holes 49 are basically the same although they have a symmetrical shape.

  (2) In the ejection head B3 exemplified in the first embodiment, as shown in FIG. 17A, the first through hole 49, the second through hole 50a, and the third through hole 50b (in the figure, these are black). However, the present invention is not limited to this. For example, the first through hole 49, the second through hole 50a, and the third through hole 50b may be arranged close to the center as in the ejection head B3 of the second modification shown in FIG. In this way, unevenness in the flow rate in the left-right direction can be made difficult to occur. Further, for example, as in the ejection head B3 of the third modified example shown in FIG. 17C, the vertical dimension of the nozzle 41 may be increased to increase the vertical width of each divided flow path. In this way, it is possible to give an appropriate thickness to the molding die used for forming each divided flow path in the manufacturing stage of the ejection head B3. In addition, the liquid remaining in the nozzle 41 after use can be easily washed.

  (3) Further, for example, as in the discharge head B3 of the fourth modified example shown in FIGS. 18A to 18C, the flow path at the base end portion in the nozzle 41 is extended so as to bite into the casing 40. It may be structured. Specifically, inside the casing 40, the nozzle extension chamber 59 at the center of the front end of the casing 40, the right first liquid dividing chamber 46 and the left second liquid dividing chamber 47 which are divided into left and right parts. A partition wall 60 is provided in the casing 40. The nozzle extension chamber 59 communicates with the base end portion in the nozzle 41, and the two partition plates 61a and 61b are connected to the base end end in the nozzle 41 from the nozzle extension chamber 59 in the same manner as the partition plates 48a and 48b of the first embodiment. Are provided continuously up to the section. That is, the flow path from the nozzle extension chamber 59 to the base end in the nozzle 41 is divided into three divided flow paths (upper divided flow path, middle divided flow path, and lower divided flow path) in the vertical direction by the partition plates 61a and 61b. It is divided. The partition wall 60 has a through-hole 62 that communicates the first liquid dividing chamber 46 and the middle dividing flow path (the dividing section between the partition plates 61a and 61b), the second liquid dividing chamber 47, and the upper part. Two through-holes 63a and 63b communicating with the divided flow path (the divided section above the partition plate 61a) and the lower divided flow path (the divided section below the partition plate 61b) are formed. Even in such a configuration, similarly to the above-described embodiment, the first liquid layer L1 and the second liquid layer L2 having the same lateral width that covers the upper surface and the lower surface of the first liquid layer L1 are formed from the tip of the nozzle 41. It is discharged in a discharge form having a three-layer cross-sectional pattern.

  (4) Further, as in a discharge head B3 of a fifth modification shown in FIGS. 19A and 19B, for example, a wall 64a that partitions the first liquid dividing chamber 46 and the nozzle extension chamber 59; An inverted V-shaped partition wall 64 composed of a wall portion 64b that partitions the second liquid partition chamber 47 and the nozzle extension chamber 59, and the nozzle 40 in the casing 40, the first liquid partition chamber 46, and You may divide | segment into the division chamber 47 for 2nd liquids. In this case, for example, as shown in FIGS. 20A to 20D, the portion of the nozzle extension chamber 59 may be configured as a triangular prism-shaped joining member 65 that is separate from the casing 40. If it does in this way, it can prevent that the metal mold | die for shaping | molding becomes complicated, and can shape | mold with a metal mold | die easily. That is, in the structure in which the portion of the nozzle extension chamber 59 is integrally formed with the casing 40 as shown in FIGS. 19A and 19B, as shown in FIG. 21A, the three through holes 62, 63a, In order to form 63b, it is necessary to remove from the discharge port a mold having a complicated tip portion. On the other hand, if the portion of the nozzle extension chamber 59 is configured as a separate joining member 65 as shown in FIGS. 20A to 20D, the molds can be separated as shown in FIG. It is possible to shorten the mold extracted from the discharge port, and to make the tip portion a simple shape. In addition, according to the configuration in which the merging member 65 is a separate body, even if the flow path in the portion of the nozzle extension chamber 59 is clogged, it can be used again by replacing the merging member 65.

  (5) In the above embodiment, the configuration in which the divided flow path is formed in the flow path in the nozzle 41 extending in the lateral direction (horizontal direction) is exemplified, but the present invention is not limited to this, for example, upward (vertical direction) A divided flow path may be formed in the flow path extending to. The discharge head 70 of the sixth modified example shown in FIGS. 22A and 22B and FIGS. 23A to 23C corresponds to the discharge head B3 of the above embodiment, and is a rectangular parallelepiped box-shaped casing. A main body 71, a lid 72 that covers the upper surface opening of the casing main body 71, and a nozzle 73 that stands on the upper surface of the lid 72 and extends upward. A pair of first stem fitting cylinders 42 and second stem fitting cylinders 43 are suspended from the left and right sides of the lower surface of the casing main body 71, respectively, as in the above embodiment. A partition wall 74 that divides the inside of the casing main body 71 into a first liquid dividing chamber 46 and a second liquid dividing chamber 47 is provided inside the casing main body 71. The partition wall 74 includes two partition wall portions 75a and 75b that divide the central portion communicating with the nozzle 73 in the casing main body 71 into three layers, and the second stem fitting cylinder 43 in each of the partition wall portions 75a and 75b. A connecting wall 76a for connecting the end portions on the side, and two connecting walls 76b for connecting the end portion on the first stem fitting cylinder 42 side in each of the partition wall portions 75a and 75b and the side wall of the casing body 71, respectively. 76c. That is, the partition wall 74 divides the central portion of the casing body 71 communicating with the nozzle 73 into three layers in the front and rear directions. For this reason, the first liquid and the second liquid in the casing body 71 flow to the nozzle 73 in a three-layer structure in which the first liquid is sandwiched between the second liquids, as in the above embodiment. A partition plate having a shape in which the two partition wall portions 75a and 75b are extended upward may be formed at least at the base end portion in the nozzle 73. Further, a member with a discharge port for bending the liquid flowing direction in the horizontal direction may be connected to the upper portion of the nozzle 73.

  (6) Moreover, the casing main body 71 and the lid 72 may be integrally formed via a hinge 77 as in the discharge head 70 of the seventh modified example shown in FIGS. 24 (A) and 24 (B), for example. . The seventh modified example is different from the sixth modified example in that it has a hinge 77, but the other configuration is the same as the sixth modified example.

  (7) Also, for example, as in the ejection head of the eighth modification shown in FIGS. 25 (A), (B) and FIGS. 26 (A) to (D), the first stem fitting cylinder 42 and the second stem fitting The landing tube 43 may be formed on the side surface instead of the lower surface of the casing body 71. The eighth modification is different from the sixth modification in the positions of the first stem fitting cylinder 42 and the second stem fitting cylinder 43, but the other configurations are the same as the sixth modification.

  (8) In the above embodiment, the discharge tool B includes the container fixing frame B1, the container fixing cylinder B2, the discharge head B3, and the pressing operation unit B4. However, at least some of these components are included. It may be formed integrally to reduce the number of parts, and conversely, it may be composed of more parts.

  (9) In the above embodiment, the configuration using an aerosol can as an accommodating portion for accommodating a liquid is exemplified, but the present invention is not limited to this. For example, a pump mechanism including a cylinder and a piston may be incorporated. Also in this case, it is possible to adopt a configuration in which the liquid is discharged by pushing down the stem, and when the push is released, the stem is raised by the upward biasing force and the discharge of the liquid is stopped. Further, the present invention is not limited to pushing down the stem, and the liquid may be discharged by other operations such as a structure in which the stem is inclined to discharge the liquid. Moreover, it is good also as a structure which is not equipped with a stem, and the method of discharge operation is not specifically limited.

  (10) As a form of the agent discharged from the discharge container, for example, a form discharged in a foam form (foam form) or a form discharged in a viscous liquid form (for example, cream form) is used. be able to. Such a discharge form is realized by a known foaming structure in each discharge container, physical properties of the containing liquid itself, and the like. Note that the higher the shape retention of the liquid, the easier it is to visually recognize the cross-sectional pattern of the discharged liquid. However, when the liquid is discharged in a state in which the cross-sectional pattern is difficult to be visually recognized (not visible), However, it is the same in that they are joined in a stacked state before being discharged, and the same effect can be obtained.

  (11) In the above-described embodiment, the configuration in which the liquids are joined in a stacked state of three layers including two outer layers and one inner layer sandwiched between them is not limited to this. You may make it make a liquid merge in the lamination | stacking state of a layer or more. Specifically, in the above embodiment, three divided flow paths are formed by the two partition plates 48a and 48b. However, four divided flow paths can be formed by using three such partition plates. In addition, five divided flow paths can be formed by using four partition plates. For example, when the first liquid and the second liquid are merged as in the above embodiment, the liquids may be merged in a stacked state of five layers in which the second liquid and the first liquid are alternately stacked. That is, two outer layers and one inner layer among the three inner layers sandwiched between these two outer layers are constituted by the second liquid, and the remaining inner layers are constituted by the first liquid. However, when three layers are used as in the above embodiment, the first liquid is disposed on the innermost side in the laminated state, and the thickness of the outer layer of the second liquid can be increased, so that the first liquid is most hardly exposed. Thus, the effect of making it difficult to expose the first liquid can be enhanced.

  (12) In the above embodiment, the two-liquid discharger that combines and discharges the first liquid and the second liquid is exemplified, but the present invention is not limited to this, and 3 stored in three or more storage units. It is good also as a structure which combines and discharges the liquid of more than a kind. For example, it can be used for discharging a three-component hair dye. Also in this case, the same effect is acquired by making it join so that a 1st agent may not become an outer layer in a lamination state. For example, the first liquid (first agent) containing a strong irritation and irritating odor to the skin, and the second liquid (second agent) and the third liquid not containing the dye, having a weak irritation and irritating odor to the skin. A three-layer laminated state sandwiched between liquids (third agent), a four-layer laminated state between the first liquid and the third liquid sandwiched between the second liquid, and the first liquid and the second liquid sandwiched between the third liquids It can be a four-layer laminated state.

  (13) In the above embodiment, the two accommodating portions are configured using two aerosol cans. However, the present invention is not limited to this. For example, a plurality of pouches (inner bags) are provided in one aerosol can. It is good also as a structure accommodated and accommodating the liquid in each pouch.

  (14) Although the hair dye is exemplified in the above embodiment, it may be a decoloring agent or a decoloring agent. The decoloring agent and the decoloring agent do not contain a dye, but otherwise the same effects as in the case of the hair coloring agent can be obtained.
