An engagement protrusion 333 that protrudes inward is provided at the upper end of the cylindrical portion 331 and engages with the on-off valve mounting groove 921 of the connection port 9 described above, thereby connecting the on-off valve 33 to the connection port portion. 9 is attached. A hemispherical body 332 is provided in the center of the upper surface of the bottomed portion 330 with the curved surface up. The hemispherical body 332 is used as a thick portion of the on-off valve 33 that seals the lower opening 96 of the connection port portion 9. The part other than the thick part of the valve 33 is a thin part. That is, the thin portion is a portion that is easily elastically deformed, and the thick portion is a portion that is difficult to elastically deform. The on-off valve 33 presses the outer peripheral surface of the hemispherical body 332 against the lower opening 96 of the connection port 9 by the elasticity of the thin portion, thereby closing the lower opening 96 of the connecting port 9 by the outer peripheral surface of the hemispherical body 332. Yes. That is, the lower opening 96 of the connection port 9 is closed. By providing the opening / closing valve 33 in the connection port portion 9 as described above, the connection port portion 9 can be closed by the opening / closing valve 33, and even if the treatment agent container 3 is tilted, the treatment agent is not spilled and is easy to use. . Further, since the on-off valve 33 has elasticity, even if the hair treatment device vibrates in a state where the treatment agent container 3 is attached to the treatment agent supply portion, the contact point between the treatment agent supply portion and the treatment agent container is reduced. It is possible to prevent clogging of the flow path of the processing agent due to wear and the like, and the opening / closing valve 33 is shaved.
[0056]
Further, in this case, the tip end surface of the contact projection 924 provided on the inclined surface 923 of the cylindrical body 92 of the connection port portion 9 is the container body 31 of the thin portion (cylindrical portion 331) of the on-off valve 33 as shown in FIG. The thin wall portion is not deformed in the direction in which the container main body 31 sandwiches the thin wall portion, and the thick wall portion is not easily displaced in the thickness direction of the processing agent container 3 or is displaced. I try not to. By adopting such a configuration, when the processing agent container 3 is replaced, the processing agent container 3 in the vicinity of the on-off valve 33 is held so as to be sandwiched in the same direction as the thickness direction of the container body 3 that the user can easily hold. In addition, the thick portion of the on-off valve 33 is not deformed, and it is possible to prevent the processing agent in the processing agent container 3 from leaking from the connection port portion 9 at the time of replacement. In particular, by providing the contact projection 924 in the connection port portion 9, even if a force is applied to the thin portion in the same direction as the thickness direction of the container body 31, the thin portion is not deformed. The structure can prevent the thick portion from being deformed, and the inclined surface 923 (the portion other than both end portions in the thickness direction of the connection port portion 9) not provided with the contact protrusion 924 and the cylindrical portion 331 of the on-off valve 33. Since a gap is formed between the inner side and the inner side, a gap is formed between the thin portion and the connection port portion 9 where the contact protrusion 924 is not provided. Other than the thickness direction of 31, it becomes easy to deform, and when the thick portion is pushed from above, it can be elastically deformed with less force.
[0057]
  At the center of the hemispherical body 332 is provided a cross-shaped cross projection 334 that protrudes upward in a plan view. The orthogonal pieces of the cross projection 334 extend in parallel to the width direction and the thickness direction of the connection port 9, respectively. ing. In this embodiment, the upper end surface of the cross projection 334 is the contact surface 338 of the on-off valve 33, and the distance between the contact surface 338 and the upper surface of the hemisphere 332 is 0.2 to 3 mm. A gap between a lower end surface (contact surface) of a connection shaft 570 that comes into contact with a contacted surface 338 described later and a surface facing the lower end surface (contact surface) of the connection shaft 570 of the hemisphere 332 of the on-off valve is 0. It is set to 2-3 mm. In the plan view of the bottomed portion 330, a communication hole is formed in a portion located outside in the width direction of the connection port portion 9 of the hemisphere 332.335Is provided.
[0058]
The on-off valve 33 is preferably formed of at least one material selected from the group consisting of ethylene propylene rubber (EPDM), nitrile butadiene rubber (NBR), and fluorine rubber. Thus, by forming the on-off valve 33 with ethylene propylene rubber (EPDM), nitrile butadiene rubber (NBR), or fluorine rubber, the chemical resistance of the on-off valve 33 can be improved. Also, ethylene propylene rubber (EPDM) ), Nitrile butadiene rubber (NBR), and fluoro rubber have low alcohol permeability, and therefore, when a treatment agent containing alcohol as described above is used, volatilization of alcohol can be prevented.
[0059]
  In addition, in the state where the processing agent container 3 is removed from the processing agent supply unit, the upper opening 95 of the connection port 9 has a plug cap 8 so as to block the connection port 9 and prevent the processing agent from leaking out. Is detachably attached. As shown in FIGS. 20, 21, and 24, the stopper cap 8 includes a head portion 80 on a circular plate and a columnar column portion 81 that protrudes downward from a central portion of the head portion 80 in plan view. A through hole is formed in the lower part of the peripheral side surface of the cylindrical portion 8193A projecting piece 810 having a diameter substantially the same as that of the projection 810 and projecting outward is provided. In the present embodiment, a plurality of protrusions 810 (two in the figure) are provided around the protrusions 810 in the vertical direction, and the protrusions 810 can be fitted in the upper holes 93a of the connection ports. This seals the through hole 93 in a sealed state. Thus, in the state where the processing agent container 3 is removed from the processing agent supply unit, the connection port 9 can be blocked by attaching the stopper cap 8 so that the processing agent can be prevented from leaking further. Moreover, it is possible to prevent dust and the like from entering the connection port portion 9 from the outside by attaching the plug cap 8.
[0060]
  When the treatment agent container 3 is attached to the connection shaft 570 of the discharge unit 5 constituting the main body of the treatment agent supply unit, as shown in FIG. 25, the connection shaft below the base portion 57 is inserted into the through hole 93 of the connection port portion 9. While inserting 570, the connecting piece 573 of the discharge part 5 is put into the hook accommodation groove 94, and the hook 573a is engaged with the hook engaging hole 910. In this state, the O-ring 571 provided on the connection shaft 570 is positioned in the middle hole 93b of the connection port 9 so that the processing agent below the O-ring 571 does not leak to the outside. By attaching the treatment agent container 3 to the connection shaft 570 as described above, the contact surface 578 which is the lower end surface of the connection shaft 570 hits the contact surface 338 of the cross protrusion 334 of the on-off valve 33 and pushes the cross protrusion 334 downward. The thin portion of the on-off valve 33 is deformed to push the thick portion downward, and a gap is formed between the outer peripheral surface of the thick portion and the lower end surface of the cylindrical body 92 of the connection port portion 9. By forming this gap, the inside of the processing agent container 3 and the connection hole 574 of the connection shaft 570 are communicated with each other. In other words, when the treatment agent container 3 is compressed, the flow of the treatment agent is shown in the figure.ArrowAs shown in FIG.335, The gap between the thick wall portion and the lower end of the cylindrical body 92 of the connection port 9, the gap between the cross projections 334 orthogonal to each other in plan view, enter the connection hole 574 of the connection shaft and enter the body hair treatment portion 6 will be supplied with a processing agent. As described above, since the opening / closing valve 33 opens and closes the connection port 9 simply by detaching the processing agent container 3 from the processing agent supply unit, the processing agent container 3 can be easily attached to the processing agent supply unit with a small force. . In addition, since the on-off valve 33 is opened and closed by utilizing the elastic deformation of the thin-walled portion, the on-off valve 33 can be opened and closed with a small force, and the connection port portion 9 is securely sealed by the thick-walled portion that is difficult to deform. Can do. In addition, by forming the thick part in a hemispherical shape, when the connection port part 9 is opened and closed, the thick part is shifted with respect to the connection part 9, or the shape of the thin part is slightly changed due to variations in molding, etc. Moreover, the circular connection port part 9 can be reliably sealed by the hemispherical thick part. Furthermore, since the on-off valve 33 has elasticity, even if the hair treatment device vibrates due to vibration of a motor or the like in a state where the treatment agent container 3 is attached to the treatment agent supply unit, the connection shaft 570 which is a treatment agent supply unit. There is little wear at the contact portion of the treatment agent container 3 with the on-off valve 33, and no clogging occurs in the treatment agent flow path, and the discharge amount of the treatment agent can be stabilized. Further, by forming the thick wall portion in a hemispherical shape, when the connection port 9 is opened and closed, the thick wall portion is displaced with respect to the connection port portion 9, or the thin wall portion is slightly changed in shape due to variations in molding or the like. Even if it does, the circular connection port part 9 can be reliably sealed by a hemispherical thick part. The clearance between the contact surface 578 of the connecting shaft 570 and the surface facing the contact surface 578 of the on-off valve 33 is 0.2 to 3 mm, so that the clearance is set to be larger than 3 mm. The deformation of the cross projection 334 of the valve 33 is suppressed, so that the on-off valve 33 is hardly deformed even when the treatment agent container 3 is attached for a long time.
[0061]
  Further, when removing the treatment agent container 3 connected to the treatment agent supply unit, the engagement between the hook engagement hole 910 and the hook 573 is released and the connection shaft 570 is pulled out from the through hole 93 of the connection port 9. Is done. In this case, when the connecting shaft 570 is pulled upward, the thick portion rises upward due to the elasticity of the thin portion, closes the lower hole 93c, and the processing agent container 3 isProcessing agentIt returns to the state which is not connected to a supply part.
