By the way, in general, the amount of hair varies depending on age, gender, or individual differences. Of course, the amount of shampoo and rinse required for shampooing also varies. In addition, since it is troublesome to stop the pressing operation of the head in the middle of the specified stroke, the user often presses down to the specified stroke all at once.
However, the amount of liquid ejected by being pushed down at once is often too much than the amount of shampoo and rinse required for actual hair washing, leading to waste of resources.

  The present invention has been made in view of the above-described conventional problems, and is capable of discharging a liquid smaller than a normal discharge amount from a pump-type liquid discharge container even if the head is pressed down until it hits. The purpose is to provide quantity adjusters and adjuster sets.

  In order to achieve the above object, a liquid discharge amount adjuster according to the present invention includes a cylinder vertically suspended from a lid cylinder fitted into an upper surface opening of a container body, and a head with a nozzle at an upper end. A liquid discharge amount from a pump-type liquid discharge container configured to discharge a liquid in a container body from a nozzle by vertically moving a piston shaft in the cylinder upward from the cylinder and moving the piston shaft up and down A liquid discharge amount adjusting device for adjusting the liquid discharge amount, comprising a plate-like main body formed of a soft material so as to be freely elastically deformable, and vertically penetrating in order to accommodate the piston shaft in the plate-like main body. Are formed, and a slit portion that communicates the shaft insertion hole with the outside of the plate-like main body is formed, and the plate-like main body at a portion facing the slit portion is separated. By Intervals of the serial slit portions are a configuration which is characterized by being configured to be larger than the diameter of the piston shaft.

  In the above-described configuration, an identification protrusion for identifying the type of liquid in the container body is formed on the outer peripheral surface of the plate-shaped body.

  And the adjuster set which concerns on this invention is comprised from the liquid discharge amount adjuster of Claim 2, and the liquid discharge amount adjuster by which the outer peripheral surface of a plate-shaped main body is formed flat. It is characterized by.

  According to the liquid discharge amount adjusting device according to the present invention, the shaft insertion hole formed through the top and bottom to accommodate the piston shaft of the pump type liquid discharge container in the plate-like body made of a soft material so as to be freely inserted. Since the slit portion that connects the shaft insertion hole and the outside of the plate-shaped main body is formed, the plate-shaped main body at the portion facing the slit portion is bent and pulled apart, so that the slit portion The interval of is expanded beyond the diameter of the piston shaft. As a result, the piston shaft can be passed through the expanded slit portion and further reach the shaft insertion hole. As a result, the stroke of the piston shaft can be shortened by the thickness of the liquid discharge amount adjusting tool, and the liquid discharge amount from the nozzle can be reduced and saved.

  Further, in the case where the identification protrusion is formed on the outer peripheral surface of the plate-shaped main body, the user can identify the type of liquid in the container main body simply by touching the identification protrusion with a hand or the like. Therefore, even when the liquid is, for example, shampoo and the eyes are covered with foam while washing the hair, and it is desired to add more shampoo, by touching the identification protrusion by groping, for example, a pump-type liquid discharge container containing shampoo It can be determined without seeing with the eyes.

  And the adjustment tool set which concerns on this invention is comprised from the liquid discharge amount adjustment tool which has an identification protrusion on the outer peripheral surface of a plate-shaped main body, and the liquid discharge amount adjustment tool by which the outer peripheral surface of a plate-shaped main body is formed flatly Therefore, for example, a liquid discharge amount adjusting tool having an identification protrusion is attached to a pump-type liquid discharge container containing shampoo, and a liquid discharge amount adjusting tool having no identification protrusion is attached to a pump-type liquid discharge container containing rinse. It can be said. Accordingly, it is possible to select a pump-type liquid discharge container in which a desired type of liquid is stored by groping without relying on visual inspection.

An embodiment of the present invention will be described with reference to the drawings. The embodiment described below is merely an example embodying the present invention, and does not limit the technical scope of the present invention. FIG. 1 is a plan view of a liquid discharge amount adjuster according to an embodiment of the present invention, FIG. 2 is a front view of the liquid discharge amount adjuster, and FIG. 3 is a perspective view of the liquid discharge amount adjuster.
In each of the drawings, a liquid discharge amount adjusting device 1 according to this embodiment is mainly composed of a plate-like main body 2 having an upper and lower thickness A formed of a soft material such as an elastomer so as to be elastically deformable. This plate-like main body 2 is formed in a substantially spade shape in plan view. Further, the plate-like main body 2 has a shaft insertion hole 3 formed so as to penetrate vertically in order to accommodate the piston shaft 12 of the pump type liquid discharge container 10 (see FIG. 5 or FIG. 6), and a shaft. A slit portion 4 that connects the insertion hole 3 and the outside G of the plate-like main body 2 is formed. The diameter of the shaft insertion hole 3 is set larger than the diameter d of the piston shaft 12. On the outer peripheral surface 2A of the plate-shaped main body 2, there are many identification protrusions 5, 5, 5,... For identifying the type of the liquid Q in the pump type liquid discharge container 10 in which the liquid discharge amount adjusting tool 1 is used. Is formed. The plate-like main body 2 in the vicinity of the slit portion 4 has a characteristic shape portion 2C that imitates the shape of a spade sword pattern.

  The liquid discharge amount adjusting tool 1 having the above-described configuration is used for a pump-type liquid discharge container 10 as shown in FIGS. The pump-type liquid discharge container 10 includes a container body 11 formed in a bottomed bottle shape having an upper surface opening 22. And the pump part 16 arrange | positioned in the container main body 11 is suspended by the lid cylinder 21 fitted by the upper surface opening part 22 of the container main body 11. As shown in FIG. The pump portion 16 includes a cylinder 17 suspended from the lower surface of the lid cylinder 21, a piston 18 slidably disposed in the cylinder 17, a lower end portion connected to the piston 18, and an upper end portion with a nozzle 14. A piston shaft 12 connected to the head 13 and a check valve 19 with a suction pipe 20 disposed under the cylinder 17. The piston shaft 12 is formed in a hollow cylindrical shape, and is exposed upward from the bearing portion 15 at the top of the lid cylindrical body 21. Then, by the vertical movement of the piston shaft 12, the liquid Q in the container body 11 is pumped up from the suction pipe 20 by the action of the piston 18 and the check valve 19, passes through the piston shaft 12 and from the nozzle 14 of the head 13 to the external G It is configured to be discharged into the water. In this pump-type liquid discharge container 10, when the liquid discharge amount adjuster 1 is not used, that is, the prescribed stroke of the piston shaft 12 until the lower surface of the head 13 hits the upper surface of the bearing portion 15 is S0 (see FIG. 6). is there.

Next, the operation of the liquid discharge amount adjusting tool 1 configured as described above will be described.
When the liquid discharge amount adjusting tool 1 is mounted on the piston shaft 12 of the pump-type liquid discharge container 10, the portions 2D and 2D of the plate-like main body 2 facing each other through the slit portion 4 are pulled apart by a hand and bent. It is done. Thereby, as shown in FIG. 4, the gap of the slit portion 4 is expanded to a gap P <b> 1 wider than the diameter d of the piston shaft 12. Subsequently, the piston shaft 12 in the external G passes through the slit portion 4 of the gap P1 expanded as described above, and is guided into the shaft insertion hole 3 as shown in FIGS. . The liquid discharge amount adjuster 1 is placed on the upper surface of the bearing portion 15.

  Thereafter, when the liquid such as shampoo is taken out, the head 13 is pushed down by hand. Among them, the lower surface of the head 13 comes into contact with the upper surface 2 </ b> B of the plate-like main body 2 of the liquid discharge amount adjusting tool 1 and stops. That is, when one liquid discharge amount adjusting tool 1 (1) is attached to the piston shaft 12, the stroke of the piston shaft 12 is S1. This stroke S1 is shorter than the normal stroke S0 by the thickness A of one liquid discharge amount adjusting tool 1. As described above, since the stroke of the piston shaft 12 is shortened, the liquid discharge amount adjusting tool 1 can save by reducing the discharge amount of the liquid Q discharged from the pump type liquid discharge container 10.

  Further, as shown by a one-dot chain line, when the second liquid discharge amount adjuster 1 (2) is mounted on the liquid discharge amount adjuster 1 (1), the stroke of the piston shaft 12 is S2. . This stroke S2 is shorter than the normal stroke S0 by the thickness (A + A) of the two liquid discharge amount adjusters 1. In this way, by increasing the number of mounted liquid discharge amount adjusting tools 1, a small amount of liquid Q can be discharged and used as necessary.

  Further, since the identification protrusions 5, 5, 5,... Are formed on the outer peripheral surface 2A of the plate-shaped main body 2, the liquid Q in the container main body 11 can be obtained simply by touching the identification protrusion 5 with a hand or the like. Can be identified. Therefore, even when the liquid Q is, for example, a shampoo and the eyes are covered with foam while washing the hair, and it is desired to add more shampoo, by touching the identification protrusion 5 by groping, for example, a shampoo containing pump type It can be determined that the liquid discharge container 10 is seen without eyes.

  Next, a set product in which a plurality of liquid discharge amount adjusting tools having different outer peripheral surface shapes are combined will be described. For example, as shown in FIG. 7, the adjuster set E includes the liquid discharge amount adjuster 1 described above in which a large number of identification protrusions 5, 5, 5,. And the outer peripheral surface 2A of the plate-like main body 2a is configured in combination with a flat liquid discharge amount adjusting tool 1a. The liquid discharge amount adjusting tool 1a is mainly composed of a plate-shaped main body 2a having a vertical thickness A formed of a soft material such as an elastomer so as to be freely elastically deformed. The plate-like main body 2a is formed in a substantially heart shape in plan view, and has a characteristic shape portion 2Ca that represents a hollow shape of the heart. Further, the plate-like main body 2 is formed with a shaft insertion hole 3 having the same shape as that of the liquid discharge amount adjusting tool 1, and a slit portion 4 a that communicates the shaft insertion hole 3 with the outside G of the plate-like main body 2. ing. In addition, the identification protrusion 5 like the liquid discharge amount adjusting tool 1 is not provided on the outer peripheral surface 2A of the plate-like main body 2a.

  Since the adjustment tool set E having the above-described configuration includes the liquid discharge amount adjustment tool 1 having the identification protrusion 5 and the liquid discharge amount adjustment tool 1a without the identification protrusion 5, for example, the liquid discharge amount having the identification protrusion 5 The adjustment tool 1 can be mounted on the pump-type liquid discharge container 1 containing shampoo, and the liquid discharge amount adjustment tool 1a without the identification protrusion 5 can be mounted on the pump-type liquid discharge container containing rinse. Thereby, the pump type liquid discharge container 10 in which the desired type of liquid Q is accommodated can be selected by hand without relying on visual inspection.
