Description

  The present invention relates to a solution foam discharge device, and can be applied, for example, when a foamy hair dye solution is sprayed on the hair.

  As a hair dye solution, a two-component hair dye type and a one-component hair dye type are conventionally used.

  In the two-component hair dye solution, the first solution is composed of an oxidation dye, an alkaline agent, a surfactant, an oxidation stabilizer, and the like, and an acid, an oxidant, a thickener, etc. are added as the second solution. However, if the oxidative dye of the first liquid and the oxidizer of the second liquid are mixed for a long time, a large dye molecule is formed by oxidative polymerization and the hair does not enter the hair. 2. Description of the Related Art A two-component liquid applicator has been proposed in the past that sometimes obtains a mixed solution, thereby decoloring the hair, and at the same time causing the dye to penetrate into the hair to cause oxidative polymerization to develop color. (See Patent Document 1).

  On the other hand, as a one-part solution applicator for applying one-part solution such as shampoo, rinse, and liquid soap to the hair or the like, one that discharges the application solution as solution bubbles has been proposed. (See Patent Document 2).

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) First Embodiment In FIG. 1, reference numeral 1 denotes a two-liquid hair dye type solution foam discharge device as a whole, and a solution foam from a solution container part 2 holding a hair dye solution via a solution supply part 3 While supplying the hair dye solution to the discharge unit 4 and supplying air for generating bubbles from the air supply unit 5 to the solution bubble discharge unit 4, the solution bubbles are discharged from the discharge port 4 </ b> A of the solution bubble discharge unit 4. Has been made.

  In the case of this embodiment, the user puts a finger on the discharge operation unit 7 and pushes the solution bubble discharge unit 4 in the direction of the solution container unit 2 to cause the solution bubble discharge operation.

  The solution container 2 is formed by blending a first liquid container 11A containing one agent composed of an oxidation dye, an alkali agent, a surfactant, and an oxidation stabilizer, an acid, an oxidant, a thickener, and the like 2 The second liquid container 11B for storing the agent.

  As shown in FIG. 2, the first liquid container 11 </ b> A and the second liquid container 11 </ b> B have a configuration in which a cylindrical appearance-shaped container is divided in half in the vertical direction, and by combining the abdominal parts 12 </ b> A and 12 </ b> B. A solution container portion 2 having the appearance of a single cylindrical container is formed.

  Portions 13A and 13B that open above the first liquid container 11A and the second liquid container 11B are closed by plate-like lid members 14A and 14B, whereby the first liquid container 11A and the second liquid container 11B are respectively closed. 1 liquid and 2nd liquid are hold | maintained.

  Cylinders 15A and 15B constituting the solution supply unit 3 are attached to the lid members 14A and 14B, and the pistons 16A and 16B of the cylinders 15A and 15B protrude upward so as to pass through the air supply unit 5, and inside the pistons 16A and 16B. The bubble generation mixing chamber 4C formed in the solution bubble discharge section 4 is passed through the circular solution guide passages 17A and 17B formed in the above and further through the outlet tubes 18A and 18B made of a flexible material. It is connected.

  In the cylinders 15A and 15B, string-wound springs 19A and 19B and balls forming check valves 20A and 20B are disposed, whereby the pistons 16A and 16B resist the elastic force of the springs 19A and 19B. When pushed downward, the solution sucked into the cylinders 15A and 15B is supplied to the bubble generation mixing chamber 4C through the solution guide passages 17A and 17B and the outlet tubes 18A and 18B.

  In this state, when the pushing force against the pistons 16A and 16B disappears, the strong elasticity of the springs 19A and 19B pushes the pistons 16A and 16B upward, thereby causing the cylinders 15A and 15B to have a negative pressure. The first and second solutions held in the first liquid container 11A and the second liquid container 11B are sucked from the suction tubes 21A and 21B attached to the lower ends of the cylinders 15A and 15B through the check valves 20A and 20B. Thus, it is prepared for the next solution supply operation.

  In the case of this embodiment, ball guide type check valves 22A and 22B are provided in the solution guide passages 17A and 17B, so that when the pistons 16A and 16B are sucking the solution into the cylinders 15A and 15B, the solution While the guide passages 17A and 17B are closed, the solution is supplied to the bubble generating mixing chamber 4C by opening the solution guide passages 17A and 17B upward when the solution in the cylinders 15A and 15B is supplied. To do.

  The air supply unit 5 has a cylindrical pushing pipe 26 whose upper end communicates with the bubble generation mixing chamber 4C and whose lower end is connected to the bellows support member 25, and is opposed to the bellows support member 25. The bubble generating air to be supplied to the bubble generating mixing chamber 4C is produced by the expansion and contraction of the bellows 28 provided between the lid members 14A and 14B and the bellows support substrate 27.

  The bellows support member 25 is fixed to the lower end of the push-in pipe 26 so as to close the lower end surface thereof, and is integrated with the upper ends of the pistons 16A and 16B penetrating the thickness.

  The upper peripheral edge of the bellows 28 is fixed to the bellows support member 25 by the fixing ring 31, and the lower peripheral edge of the bellows 28 is fixed to the bellows support substrate 27 by the fixing ring 32.

  The pistons 16A and 16B are provided with a pair of spring receiving plates 34 and 35 each having a string-wound spring 33A and 33B disposed therebetween so as to penetrate therethrough.

  The lower spring receiving plate 35 is fixed to the pistons 16A and 16B, whereas the upper spring receiving plate 34 facing the pistons 16A and 16B is integrated with the bellows support member 25 to the pistons 16A and 16B. It can be moved up and down along.

  Thus, when the springs 33A and 33B are compressed by the bellows support member 25 and the spring receiving plate 34, the bellows 28 is contracted downward, while the springs 33A and 33B are stretched. Accordingly, when the spring receiving plate 34 and the bellows support member 25 are moved upward, the bellows 28 extends to the original return state.

  When the bellows 28 is contracted, the air in the bellows 28 passes through the space in the push pipe 26 and bubbles are generated through the air supply holes 4E formed in the closing plate 4D formed between the bubble generating and mixing chamber 4C. It is fed into the mixing chamber 4C as bubble generating air.

  That is, when the user pushes the solution bubble discharge part 4 downward to move the push pipe 26 downward against the springs 19A and 19B and 33A and 33B (this is called a downward movement operation). Alternatively, when the pushing pipe 26 is moved upward by the elastic force of the springs 19A and 19B and 33A and 33B (this is called a return operation), supply of the solution from the pistons 16A and 16B and generation of bubbles from the bellows 28 Supply air.

  In this embodiment, click mechanisms 40A and 40B for vertical movement as shown in FIG. 3 are provided between the bellows support member 25 and the pistons 16A and 16B.

  The click mechanism 40A (40B) has a through hole 41A (41B) that allows the piston 16A (16B) to pass through the thickness of the bellows support member 25, and the piston 16A (16B) has a through hole 41A (41B). The click protrusion 42A (42B) protrudes from the surface facing the bellows support member 25, and the click protrusion 43A (43B) protrudes from the surface of the bellows support member 25 facing the piston 16A (16B).

  The click protrusion 42A (42B) and the click protrusion 43A (43B) of the bellows support member 25, as shown in FIG. 3 (A), are shown in FIG. The click projection 43A (43B) is at the position of the return height level LV1, and the top surface of the tip of the click projection 42A (42B) of the piston 16A (16B) is engaged with the bottom surface of the tip.

  In this state, when the solution foam discharge portion 4 is pushed downward, the bellows support member 25 fixed to the lower end portion of the push pipe 26 moves downward from the return height level LV1, as shown in FIG. The piston lowers to the lower piston lower limit level LV2.

  At this time, since the click protrusion 42A (42B) of the piston 16A (16B) is engaged with the click protrusion 43A (43B) of the bellows support member 25, the piston 16A (16B) is moved together with the piston lower limit height level. Lower to LV2.

  When the piston 16A (16B) moves to the lower limit position of the cylinder 15A (15B), the first liquid (second liquid) in the cylinders 16A and 16B is discharged into the bubble generation mixing chamber 4C of the solution bubble discharge unit 4.

  At the same time, when the bellows support member 25 is lowered to the piston lower limit height level LV2, the spring receiving plate 35 is lowered to a position where it comes into contact with the bellows support substrate 27.

  By this operation, the bellows 28 is compressed by an amount corresponding to the piston lower limit height level LV2 from the return height level LV1, so that the air inside passes through the through hole 41A (41B) of the click mechanism 40A (40B). It flows upward and is supplied to the bubble generation mixing chamber 4C from the air supply hole 4E as bubble generation air.

  Subsequently, when the solution bubble discharger 4 is pushed downward thereafter, the bellows support member 25 is further pushed by the push pipe 26 as shown in FIG. ) Gets over the click protrusion 42A (42B) of the piston 16A (16B) and is disengaged from the click protrusion 42A (42B), whereby the bellows support member 25 is lowered further downward. go.

  The state at this time is a state in which the bellows support member 25 moves further downward even though the piston 16A (16B) has been lowered to the lower limit position. By compressing, the compressed air is supplied from the bellows 28 to the bubble generating mixing chamber 4C.

  As a result, in the bubble generation mixing chamber 4C, only the air from the bellows 28 is supplied without supplying the first liquid (second liquid) from the piston 16A (16B).

  Thereafter, when the spring receiving plate 35 fixed to the pistons 16A and 16B comes into contact with the bellows support substrate 27 and the pistons 16A and 16B are stopped, the bellows support member 25 as shown in FIG. The click protrusion 43A (43B) is stopped at the position of the bellows lower limit height level LV3.

  Thus, the supply operation of the first liquid and the second liquid from the cylinders 15A and 15B to the bubble generation mixing chamber 4C and the supply operation of the bellows 28 to the bubble generation mixing chamber 4C are completed.

  In this state, when the user stops the push-down operation on the solution bubble discharge unit 4, the pistons 16A and 16B are pushed back upward by the elastic force of the springs 19A and 19B of the cylinders 15A and 15B.

  At this time, since the springs 19A and 19B of the cylinders 15A and 15B have a stronger elasticity than the springs 33A and 33B of the bellows 28, the bellows support member 25 is pushed up while the springs 33A and 33B are compressed.

  Thus, as shown in FIG. 3 (E), the bellows support member 25 and the piston 16A (16B) return upward together, so that the click projection 43A (43B) and the click projection 42A (42B) are substantially the same. Returning upward while maintaining the same interval.

  Eventually, when the pistons 16A and 16B return to the upper stationary position, as shown in FIG. 3F, the click projection 42A (42B) stops in a state where the click protrusion 42A (42B) has returned to the height of the return height level LV1.

  At this time, while the spring receiving plate 35 fixed to the pistons 16A and 16B is stopped, the spring receiving plate 34, and hence the bellows support member 25 continues to return upward due to the elastic force of the springs 33A and 33B. As a result, the click projection 43A (43B) of the bellows support member 25 approaches the click projection 42A (42B) of the pistons 16A and 16B that are stationary.

  Eventually, when the springs 33A and 33B of the bellows 28 return to their original extended state, as shown in FIG. 3G, the click projection 43A (43B) of the bellows support member 25 has already reached the return height level LV1. After returning to the click protrusion 42A (42B) that has been returned, it returns to the return height level LV1 so as to be in a return state in which the upper surface of the tip is engaged with the lower surface of the tip.

  Thus, while the bellows support member 25 returns to the state shown in FIG. 3G through the state shown in FIG. 3F, the bellows 28 is compressed by the resilient force of the springs 19A and 19B and the resilient force of the springs 33A and 33B. When the air pressure in the bellows 28 becomes negative pressure during this period, the air suction member 36 is opened and air is taken into the bellows 28 through the air suction passage 37. Thus, the user prepares for the next operation of pushing in the solution bubble discharger 4.

  In the case of this embodiment, an air suction member 36 having an L-shaped cross section and being thin and soft, for example, an annular shape made of a rubber material, is provided on the lower surface portion of the bellows support member 25 in the bellows 28. When the air pressure of the air becomes negative, external air is sucked into the bellows 28 by opening the air suction member 36 from an air suction passage 37 provided adjacent to the air suction member 36. When the pressure is increased and the pressure is increased, the air suction member 36 is closed, and the air in the bellows 28 is supplied into the push pipe 26 as bubble generating air through the through holes 41A and 41B of the click mechanisms 40A and 40B. ing.

  As shown in FIG. 4, the solution bubble discharge unit 4 forms a bubble generation mixing chamber 4C in a cylindrical body 4F having a closing plate 4D connected to the push pipe 26 of the air supply unit 5 at the lower portion, and discharges at the tip thereof. The outlet 4A is provided.

  A foam generating member 4G made of a porous synthetic resin material is provided on the front end side of the closing plate 4D of the cylindrical body 4F, and a support bar 4H extending rearward from the rear end is connected to the tail plug 4I. The foam foam member 4G can be removed together with the tail plug 4I for cleaning or replacement.

  In the case of this embodiment, a first liquid supply hole 4J1 to which the first liquid outlet tube 18A is coupled and a second liquid supply hole to be coupled to the second liquid outlet tube 18B are connected to the central portion of the closing plate 4D. 4J2 is provided so as to be lined up on the left and right, and an air supply hole 4E is provided at the rear end side position of the first liquid and second liquid supply holes 4J1 and 4J2.

  Thus, when the first liquid and the second liquid are supplied from the cylinders 15A and 15B to the first liquid and the second liquid supply holes 4J1 and 4J2 via the pistons 16A and 16B, they are simultaneously supplied from the air supply hole 4E. The bubble-generating air is discharged from the discharge port 4A while mixing the first liquid and the second liquid and generating a solution bubble in the bubble-generating member 4G by the bubble-generating air.

  In the above configuration, when the user operates to push in the solution foam discharge section 4 of the solution foam discharge apparatus 1 in a stationary state, the push pipe 26 of the air supply section 5 is pushed down in the direction of the solution container section 2. As a result, the pistons 16A and 16B move downward with respect to the cylinders 15A and 15B, whereby the cylinders 15A and 15B are sucked from the first liquid container 11A and the second liquid container 11B through the suction tubes 21A and 21B. The liquid and the second liquid pass through the solution guide passages 17A and 17B of the pistons 16A and 16B, and are further supplied to the cylindrical body 4F of the bubble generating and mixing chamber 4C through the outlet tubes 18A and 18B.

  At the same time, when the bellows support member 25 moves downward together with the pistons 16A and 16B (FIGS. 3A to 3B), the air in the bellows 28 is passed through the through holes 41A (41B) of the click mechanisms 40A and 40B. Through the air supply hole 4E, it is supplied to the bubble generation mixing chamber 4C.

  At this time, when the first liquid and the second liquid mixed in the bubble generation mixing chamber 4C pass through the bubble generation member 4G together with the supplied bubble generation air, they are bubbled and discharged from the discharge port 4A.

  Thus, the user discharges the solution bubbles discharged from the discharge port 4A of the solution bubble discharge unit 4 toward the hair while operating the discharge operation unit 6 and the solution bubble discharge unit 4 with one hand.

  At that time, the first liquid and the second liquid are supplied to the solution bubble discharge unit 4 almost simultaneously, and are discharged from the discharge port 4A together with the bubble generating air, thereby mixing the mixed solution with the oxidizing agent. In addition, the mixed solution of the first liquid and the second liquid can be uniformly and safely applied to the hair while sufficiently satisfying the coloring action conditions.

  Since the amount of application is just the amount of liquid used by the user for one application operation, the excess first liquid and second liquid can be left in the first liquid container 11A and the second liquid container 11B.

  Thus, the solution remaining in the solution container 2 can be used without waste for the next coating operation.

  In the case of this embodiment, when the coating operation is not performed, the user inserts the sealing plug 4L into the discharge port 4A of the solution bubble discharge unit 4 so that the bubble generation mixing chamber 4C including the bubble generation member 4G as a whole is inserted. It can be sealed from the outside air, so that even if a residue of the solution remains in the foam generating member 4G, it does not dry and cause clogging.

  In the case of this embodiment, the solution container portion 2 is screw-coupled at the mouth portions 13A and 13B so as to have a gap at the lower end portion of the cylindrical housing 28A that houses the bellows 28 of the air supply portion 5. When the first and second solutions are sucked into the cylinders 15A and 15B, the solution sucking operation is smoothly performed by replenishing the outside air corresponding to the sucked liquid amount through the screw coupling portion. Yes.

  Similarly, the upper end portion of the housing 28A of the bellows 28 is screwed to the lower end portion of the discharge operation portion 6 that slidably supports the push pipe 26, and when the bellows 28 extends, the push pipe 26 The outside air is sucked into the housing 28 </ b> A of the bellows 28 through a gap between the discharge operation unit 6.

  According to the above configuration, for a two-component hair dye that requires a color development reaction, even if the user is a general customer, it is possible to safely remove the hair without damaging the hands and without impairing the color development effect with a simple operation. A hair dyeing tool capable of uniformly dyeing hair can be realized.

(2) Second Embodiment FIGS. 5 and 6 show a second embodiment. In the case of FIG. 1, as shown in FIG. 5 has a structure in which a foam generating member 4G is provided in the solution foam discharge section 4 and a sealing plug 4L is inserted into the discharge port 4A. Instead, in the case of FIG. 5, bubbles are generated in the push pipe 26. The member 6 </ b> A is provided, and the opening / closing member 51 is provided in the solution bubble discharge unit 4.

  As shown in FIG. 6 (A), the solution bubble discharge section 4 is provided with a cylindrical opening / closing member 51 in a cylindrical body 4F having a discharge port 4A formed at the tip thereof, and is provided in the push pipe 26. The communication state between the communication port 4K communicating with the solution bubble generating unit 6 and the discharge port 4A can be selected.

  That is, the opening 51A is formed at a position corresponding to the communication port 4K of the opening / closing member 51C, and the user rotates the knob 51B that protrudes backward from the end opposite to the discharge port 4A of the cylindrical body 4F. When the opening 51A is aligned with the communication port 4K, the solution bubbles generated from the solution bubble generating unit 6 are communicated with the discharge port 4A so that the solution bubbles can be discharged from the solution bubble discharging unit 4.

  On the other hand, as shown in FIG. 6B, when the user rotates the knob 51B, the opening / closing member 51 is positioned at a position where the opening 51A is not communicated with the communication port 4K (for example, a position rotated by 180 °). When this is done, the solution bubbles supplied from the solution bubble generating unit 4 are closed by the opening / closing member 51, whereby the communication port 4K is adjusted to be shielded from the discharge port 4A.

  In the case of this embodiment, as shown in FIG. 6 (C), a seal projection 51C that acts as an O-ring is formed on the outer peripheral surface of the opening / closing member 51, whereby the cylindrical body 4F of the solution foam discharge section 4 is formed. Leakage does not occur between the discharge port 4A and the communication port 4K through the space between the inner peripheral surface and the outer peripheral surface of the opening / closing member 51.

  The solution bubble generating unit 6 has a configuration in which a bubble generating member 6A is provided inside a push pipe 26 at a tip portion thereof, and a cylindrical holding member 6C having a lower end closed by a bottom plate 6B is fitted.

  As shown in FIG. 6 (D), the bottom plate 6B of the holding member 6C has lead-out tubes 18A and 18B led out from the first and second liquid pistons 16A and 16B, similarly to the closing plate 4D in FIG. The first liquid supply hole 6D1 and the second liquid supply hole 6D2 are connected to each other, and the air supply hole 6E is supplied with bubble generation air from the bellows 28.

  Thus, the first liquid and the second liquid supplied from the first liquid supply hole 6D1 and the second liquid supply hole 6D2, and the bubble generating air supplied from the air supply hole 6E are the bottom plate 6B and the bubble generating member 6A. The solution bubbles are generated by passing through the bubble generating member 6A after being mixed in the space between and the solution from the opening and closing member 51 through the communication port 4K of the solution bubble discharging unit 4 and the opening 51A of the opening and closing member 51. It is discharged to the discharge port 4A of the bubble discharge unit 4.

  According to the above configuration, when the user pushes the solution bubble discharge unit 4, the supply operation of the pistons 16 </ b> A and 16 </ b> B and the bellows 28 is performed in the same manner as described above with reference to FIGS. 1 to 4. Uniform solution bubbles can be discharged from the discharge port 4A by a simple operation.

  Accordingly, when the user stops the discharge operation of the solution bubbles, the knob 51B of the opening / closing member 51 is rotated so that the opening 51A is positioned so as not to communicate with the communication port 4K (FIG. 6B). ), It is possible to prevent the solution bubble generating part 6 from being exposed to the outside air of the discharge port 4A, so that even if a residue of the solution remains on the bubble generating member 6A, it is not allowed to dry, thereby preventing clogging. You can

  As a result, it is possible to realize a simple solution foam discharge device 1 that can repeatedly use the solutions in the first liquid container 11A and the second liquid container 11B as much as the user needs.

(3) Third Embodiment FIGS. 7 to 9 show a third embodiment, and corresponding parts to those in FIG.

  In the case of FIG. 7, the end portions of the pistons 16A and 16B of the cylinders 15A and 15B disposed in the first liquid container 11A and the second liquid container 11B are integrally coupled by a connecting member 53 in the bellows 28.

  Further, outlet pipes 54A and 54B made of a flexible material are connected to the tips of the pistons 16A and 16B, and the outlet pipes 54A and 54B pass through the inside of the push-in pipe 26, and the solution bubbles shown in FIGS. It is connected to the first liquid and second liquid supply holes 6D1 and 6D2 provided on the bottom plate 6B of the solution bubble generating section 6 having the same configuration as the generating section 6.

  A cylindrical guide groove 55 is formed on the inner wall of the lower end of the push-in pipe 26, and a cylindrical vertical movement member 56 is fitted into the guide groove 55 so as to move up and down.

  The connecting member 53 is fixed to the lower end surface of the vertical movement member 56, and when the vertical movement member 56 moves up and down, the pistons 16A and 16B of the cylinders 15A and 15B move up and down together.

  In the case of this embodiment, a bellows-returning spring 57 made of a string-wound spring is provided between the spring receiving plate 34 and the bellows support substrate 27, and the original bellows 28 compressed by the spring 57 is extended. It is made to be able to return to the state.

  In the case of this embodiment, the push pipe 26 is provided with two fulcrum members 58A and 58B, and the fulcrum members 58A and 58B are centered on the fulcrum 60 of the external housing 59 as shown in FIG. When the handle 61 is attracted, the pushing pipe 26 is moved downward through the fulcrum members 58A and 58B.

  In the above configuration, when the user moves the push pipe 26 downward by pulling the handle 61, as shown in FIG. 9, the click mechanism 62 provided between the push pipe 26 and the vertically moving member 56 is used. In accordance with the pushing operation of the pushing pipe 26, the compression operation of the pistons 16A and 16B of the cylinders 15A and 15B and the compression operation of the bellows 28 are interlocked.

  When the solution foam discharge section 4 is in a stationary state, as shown in FIG. 9A, the return height level in a state in which the click projection 26X of the push pipe 26 is engaged with the click projection 56X of the vertical movement member 56. It is in the position of LV11.

  When the user performs a downward movement operation to move the push pipe 26 downward via the handle 61 from this state, as shown in FIG. 9B, the click protrusions 26X and 56X remain in the engaged state. The vertical movement member 56 moves downward together with the pressing operation of the pressing pipe 26.

  At this time, the pistons 16A and 16B of the cylinders 15A and 15B are moved downward when the vertical movement member 56 is moved downward, so that the pistons 16A and 16B compress the solution in the cylinders 15A and 15B.

  At this time, the solution in the cylinders 15A and 15B is supplied from the pistons 16A and 16B to the solution bubble generator 6 through the outlet pipes 54A and 54B.

  Along with this, the bellows support member 25 is moved downward by the downward movement of the vertical movement member 56, thereby compressing the bellows 28, so that the air in the bellows 28 passes through the air supply hole 6E and enters the solution bubble generator 6. Supplied.

  As a result, the first liquid and the second liquid supplied from the first liquid container 11A and the second liquid container 11B are mixed in the solution bubble generating unit 6, and the bubble generating member together with the supplied bubble generating air. It becomes a solution bubble from 6A, and is discharged from the discharge port 4A of the solution bubble discharge part 4. FIG.

  Thus, as shown in FIG. 9B, when the pushing pipe 26 moves downward to the cylinder lower limit level LV12 where the connecting member 53 contacts the bellows support substrate 27, the vertical moving member 56 stops without being lowered any further. However, when the user further operates the handle 61 to push in the push pipe 26, as shown in FIG. 9C, the click protrusion 26X of the push pipe 26 passes over the click protrusion 56X of the vertical movement member 56, and further. Go down.

  At this time, the pushing pipe 26 can be moved downward along the periphery of the vertical movement member 56 by the guide groove 55, thereby further compressing the bellows 28 via the bellows support member 25.

  At this time, since the solution is not already supplied from the cylinders 15A and 15B to the solution bubble generation unit 6, only the supplied air passes through the bubble generation member 6A, so that the bubble component remaining in the bubble generation member 6A It is discharged to the outside from the discharge port 4A.

  Thereafter, as shown in FIG. 9D, when the upper end surface 55A of the guide groove 55 of the push pipe 26 abuts on the upper end face of the vertical movement member 56, the push pipe 26 cannot move further downward. The click projection 26X stops at the pushing pipe lower limit level LV13.

  Thus, when the user completes the operation of discharging the solution bubbles once and the user stops the pulling operation on the handle 61, the pistons 16A and 16B, and hence the bellows support member 25, are generated by the elastic force of the cylinders 15A and 15B and the springs 19A and 19B. 7B returns to the original position and moves to the state of FIG. 7B through the state of FIG. 7C.

  At this time, the spring 57 in the bellows 28 also exerts a resilient force to push up the bellows support member 25, so that the bellows 28 returns to the original stationary state of FIG.

  Thus, after the vertical movement member 56 stops at the cylinder lower limit level LV12 (FIG. 7 (B)), the pushing pipe 26 continues to move downward (FIGS. 7 (C) to (D)). 54A and 54B can implement | achieve by carrying out a deformation | transformation operation | movement by being drawn in from the through-holes 26A and 26B provided in the lower end part of the pushing pipe 26 to the hand-held part.

  In the case of this embodiment, the downward movement of the push-in pipe 26 is performed by operating the handle 61 provided for the fulcrum members 58A and 58B. Therefore, a lid 62 is provided at the upper end of the housing 28A of the bellows 28. It is screwed and held while maintaining a gap so that outside air can be introduced into the bellows 28.

  According to the configuration of FIGS. 7 to 9, the user needs to draw the solution in the first liquid container 11 </ b> A and the second liquid container 11 </ b> B from the cylinders 15 </ b> A and 15 </ b> B to the solution bubble generator 6 only by pulling the handle 61. In addition to supplying and mixing in an amount, the foam generated in the foam generating member 6A by the air supplied from the bellows 28 can be discharged to the discharge port 4A through the opening / closing member 51, and from the cylinders 15A and 15B. By allowing the air in the bellows 28 to flow further through the foam generating member 6A after the supply is completed, the generated foam can be released without leaving the foam generating member 6A.

  Thus, it is possible to realize the solution foam discharge device 1 that is convenient to handle and can apply a completely uniform solution.

(4) Fourth Embodiment FIGS. 10 and 11 show a fourth embodiment. As shown in FIG. 7 through FIG. Is constituted by connecting tubes 65A and 65B that operate in conjunction with the bellows support member 25 and a lead-out pipe 66.

  In this case, the solution supply unit 3 is allowed between the bottom plate 6B of the solution bubble generating unit 6 and the connecting member 53 of the pistons 16A and 16B for the first and second liquids in the push pipe 26 and the bellows 28. Connection tubes 65A and 65B made of a flexible synthetic resin material and a circular outlet pipe 66 made of a synthetic resin material are provided.

  The outlet pipe 66 is formed with first and second liquid solution paths 66A and 66B separated by a partition wall 66C formed in a circular cross section, and the lower ends of the solution paths 66A and 66B. The portion is coupled to connecting tubes 65A and 65B whose lower ends are connected to pistons 16A and 16B at connecting member 53, respectively.

  As shown in FIG. 11, connecting holes 6AX and 6BX communicating with the solution passages 66A and 66B are formed in the bottom plate 6B of the solution bubble generating unit 6, and the solution passages 66A and 6BX pass through the connecting holes 6AX and 6BX. The first liquid and the second liquid supplied from 66 </ b> B are introduced into the solution bubble generating unit 6.

  A closing plate 66D that closes the opening is provided on the lower end surface of the outlet pipe 66, and a cylindrical guide tube member 66E projects downward from the lower surface of the outlet pipe 66. When the outlet pipe 66 descends downward, The guide tube member 66E is inserted into and guided by a rod-shaped guide element 27A protruding upward from the bellows support substrate 27.

  The connecting tubes 65A and 65B connect the pushing force applied from the outlet pipe 66 without deformation until the connecting member 53 contacts the bellows support substrate 27 when the outlet pipe 66 descends downward. When the connecting member 53 comes into contact with the bellows support substrate 27 and cannot move downward any more, it deforms outward in accordance with the descending operation of the outlet pipe 66. As a result, the descending operation of the outlet pipe 66 is allowed.

  In the case of this embodiment, the opening at the lower end surface of the push-in pipe 26 communicates with the space in the bellows 28, so that the air inside the bellows 28 is compressed when the bellows 28 is compressed, as shown in FIG. 6 is supplied to the solution bubble generator 6 through the through holes 6CX and 6DX provided in the bottom plate 6B.

  In the case of this embodiment, a click mechanism such as the click mechanism 62 for vertical movement as described above with reference to FIG. 9 is not provided between the push pipe 26 and the lead pipe 66. When the downward force is applied to the pipe, the outlet pipe 66 is moved downward together with this, and when the downward movement is released, the downward force is released from the push pipe 26 and the return pipe is returned. In addition, the outlet pipe 66 performs a return operation.

  In the above configuration, when the user operates the handle 61 to push the push pipe 26 downward via the fulcrums 58A and 58B, the lead-out pipe 66 and the connecting tubes 65A and 65B are moved according to the downward movement of the push pipe 26. Due to the downward movement, the pistons 16A and 16B are compressed, so that the solution in the cylinders 15A and 15B passes from the pistons 16A and 16B through the connecting tubes 65A and 65B, and further in the solution passages 66A and 66B of the outlet pipe 66. The solution is supplied to the solution bubble generator 6 through the connection holes 6AX and 6BX.

  At the same time, the bellows support member 25 is moved downward according to the downward movement of the push pipe 26, so that the bellows 28 is compressed, so that the air in the bellows 28 passes through the through holes 6CX and 6DX and the solution bubbles. It is supplied to the generator 6.

  Thus, in the solution bubble generating unit 6, the first and second liquids supplied from the connecting holes 6AX and 6BX and the air supplied from the through holes 6CX and 6DX are mixed to generate a solution bubble in the bubble generating member 6A. The solution bubbles are discharged from the discharge port 4A of the solution bubble discharge portion 4 through the opening 51A of the opening / closing member 51.

  Eventually, the connecting member 53 coupled to the pistons 16A and 16B is brought into contact with the bellows support substrate 27 by the pushing operation of the pushing pipe 26, and the downward movement operation is stopped.

  However, when the pushing pipe 26 is further pushed, the connecting tubes 65A and 65B are deformed based on the flexibility thereof, so that the guide tube member 66E connected to the lower end of the outlet pipe 66 is applied to the bellows support substrate 27. Further downward movement is continued while being guided by the provided guide 27A.

  Accordingly, the bellows 28 continues to supply the internal air to the solution bubble generating unit 6 by continuing the compression operation.

  At this time, since the supply of the first liquid and the second liquid from the solution passages 66A and 66B is stopped, the bubble generating member 6A opens and closes the solution remaining inside by the air supplied from the through holes 6CX and 6DX. Blow away toward the opening 51A of the member 51.

  Thus, when one discharge operation is completed and the user releases the operating force on the handle 61, the pistons 16A and 16B are returned upward by the strong resilience of the springs 19A and 19B provided on the cylinders 15A and 15B.

  At this time, the connecting tubes 65A and 65B also operate to return to the original shape from the deformed state due to their flexibility, and thus the outlet pipe 66 and therefore the pushing pipe 26 return to the return position.

  At this time, the bellows 28 returns to a swelled state by the return operation of the bellows support member 25.

  According to the above configuration, based on the deformation operation of the flexible connecting tubes 65A and 65B, the first liquid and the first liquid supplied from the cylinders 15A and 15B based on the initial downward movement operation of the push pipe 26 At the same time as the mixing operation of the two liquids is performed in the solution bubble generation unit 6, the solution bubbles are supplied from the bubble generation member 6 </ b> A to the solution bubble discharge unit 4 by the supply of air based on the compression operation of the bellows 28.

  Accordingly, the user can perform a hair dyeing operation on the hair using the solution bubbles discharged from the discharge port 4A.

  In addition to this, by supplying the air in the bellows 28 to the foam generating member 6A in a state where the supply of the first liquid and the second liquid is stopped by the second half of the pushing pipe 26, the foam generating member 6A The remaining mixed solution can be blown off.

  Here, when the user stops the application operation, if the communication between the solution bubble generating unit 6 and the discharge port 4A is blocked by rotating the opening / closing member 51, the bubble generating member 6A is prevented from drying. In the state, it can prepare for subsequent hair dyeing operation.

(5) Fifth Embodiment FIG. 12 shows a fifth embodiment, in which parts corresponding to those in FIGS. 10 and 11 are given the same reference numerals.

  In the case of FIG. 10, the upper ends of the pistons 16A and 16B are connected to the solution passages 66A and 66B at the lower end portion of the outlet pipe 66 via the connecting tubes 65A and 65B. Instead of this, the connecting pipe portion 77 provided so as to close the lower end of the outlet pipe 66 is directly connected to the outlet pipe 66.

  Thus, in this embodiment, as shown in FIG. 10, the air supply operation by the bellows 28 after the supply operation of the first liquid and the second liquid by the cylinders 15A and 15B is not performed. ing.

  Further, in this embodiment, the pushing operation of the pushing pipe 26 is not performed by the handle 61 and the fulcrum members 58A and 58B as in the case of FIG. This is done by pushing in.

  On the other hand, in the case of this embodiment, the check valves 71A and 71B below the cylinders 15A and 15B have upper ends at the solution guide passages 17A and 16B of the pistons 16A and 16B on the center lines of the cylinders 15A and 15B. Support rods 72A and 72B inserted into 17B are fixed.

  Outside the support rods 72A and 72B, circular auxiliary pipes 73A and 73B that move up and down together with the pistons 16A and 16B are provided, and upper check valves 74A and 74B are weakly resilient springs at their tips. The upper openings of the auxiliary pipes 73A and 73B can be closed by being pushed downward by 75A and 75B.

  Thus, when the pistons 16A and 16B are moved downward while compressing the springs 19A and 19B having a strong resilience, the hydraulic pressure in the cylinders 15A and 15B increases, so that the lower check valves 71A and 71B are closed. Operate.

  At this time, the lower end flanges 73AX and 73BX of the auxiliary pipes 73A and 73B move downward together with the pistons 16A and 16B while abutting against the lower end surfaces of the pistons 16A and 16B, whereas the upper check valves 74A and 74B Is pushed up by the flow of the solution, so that the solution in the cylinders 15A and 15B flows upward through the auxiliary pipes 73A and 73B and further through the check valves 74A and 74B.

  At this time, the solution flowing through the auxiliary pipes 73A and 73B passes through the solution passages 66A and 66B of the outlet pipe 66 provided in the pushing pipe 26, and is connected to the connecting holes 6AX and 6BX formed in the bottom plate 6B (FIG. 11). The solution is supplied to the solution bubble generating unit 6 through.

  In the configuration shown in FIG. 12, when the user pushes the solution bubble discharge unit 4 downward, and the push-in pipe 26 moves down, the pistons 16 </ b> A and 16 </ b> B move down via the connecting pipe 77.

  At this time, the solution in the cylinders 15A and 15B passes through the auxiliary pipes 73A and 73B by the downward movement of the pistons 16A and 16B, and pushes up the weak springs 75A and 75B of the check valves 74A and 74B. 66 are supplied to 66 solution passages 66A and 66B.

  Thus, the solution supplied to the solution passages 66A and 66B is mixed with the air supplied from the bellows 28 before the bubble generating member 6A and passes through the bubble generating member 6A, thereby opening and closing the solution bubble discharge part 4. It is discharged as a solution bubble from the discharge port 4A through the member 51.

  When the user stops pressing the solution bubble discharge part 4 after the discharge operation is finished, the pistons 16A and 16B are returned by the springs 19A and 19B having strong resilience of the cylinders 15A and 15B. At this time, the cylinders 15A and 15B are restored. The lower check valves 71A and 71B are opened by lowering the internal hydraulic pressure, and the upper check valves 74A and 74B open the upper end openings of the auxiliary pipes 73A and 73B by the springs 75A and 75B having a weak elasticity. Block.

  Thus, the first and second solutions in the first and second solution containers 11A and 11B are sucked into the cylinders 15A and 15B through the suction tubes 21A and 21B, so that the next user can perform a pressing operation on the solution discharge unit 4. Prepare.

  According to the above configuration, the solution in the solution bubble discharge unit 4 is mixed with the air in the bellows 28 simultaneously with the solution in the first and second solution containers 11A and 11B by the user's pressing operation on the solution discharge unit 4 and the release thereof. The foam solution can be discharged from the discharge port 4A.

  Thus, the user can uniformly apply the two-component liquid mixture for one use to the hair by a simple and safe operation.

  Accordingly, the upper check valves 74A and 74B are closed by the springs 75A and 75B having a weak spring force so that the openings of the auxiliary pipes 73A and 73B are closed. Even if it exists, it can seal reliably so that a solution may not always leak from cylinder 15A and 15B.

By operating, the solution in the cylinder 15 passes through the solution guide passage 17 and is further supplied to the foam generating member 4G through the upper check valve 22.

  The outlet side passage of the bubble generating member 4G forms a discharge passage 4H, and the solution bubbles generated in the discharge passage 4H are discharged from a discharge port 4A in which a sealing plug 4L can be detachably provided.

  In the case of this embodiment, the bellows support member 25 can suck air from the outside into the bellows 28 via the air suction valve 36 attached to the flange member 80 provided on the piston 16.
