  The above-mentioned appropriate amount dispensing device does not need to be provided with a plunger tube, can use almost all of the liquid stored in the container body, and after use, only the container body needs to be replaced. Although it is excellent in exhibiting various effects such as being quite economical, there is a dislike that the manufacturing process becomes complicated because a complicated structure such as a bellows or a pushing member is adopted. Further, even when the liquid is discharged, a fine operation of tilting the both pushing members while the container is inverted is required.

  The present invention has been made in view of the above points, and proposes an excellent quantitative distributor that has a simple structure, has a small number of members, is easy to handle, and can exhibit the above-described conventional characteristics.

  The quantitative distributor of the present invention includes a case body, a nozzle member, a container body, and a cap.

  The case body is formed of a synthetic resin or the like, and has a cylindrical shape in which a top nozzle member is fitted and a lower end is opened.

  The nozzle member is made of a flexible and elastic material such as elastomer, has a cylindrical shape that penetrates the top of the case body, and is fixed to the upper part of the case body. And an elastic cylinder part. The discharge nozzle has a discharge hole at the tip, and the base end is fitted and fixed to the upper end of the case body.

  The elastic cylinder is connected to the container body and is elastically deformed by pressing the container body to increase the internal pressure. Therefore, the elastic cylinder portion is suspended with a gap so as to be elastically deformable with the case body. . Further, it is preferable that the upper portion is tapered so that the elastic deformation is always substantially constant. Thereby, it is easy to cause a certain elastic deformation so that a taper part spreads.

  The cap is preferably detachably attached to the nozzle member. In this case, the cap is generally screwed. Therefore, it is preferable to provide means for preventing the nozzle member from rotating relative to the case body. As a result, it is possible to prevent idling even if the cap is repeatedly screwed and unscrewed. Although various forms can be adopted as the rotation preventing means, it is configured by projecting a vertical ridge on the inner circumference of the case and fitting a groove on the outer periphery of the flange projecting from the outer periphery of the nozzle member to the vertical ridge it can. Since the nozzle member is made of an elastic material, such a solid rotation preventing means is preferably employed.

  The container body is a container in which a stored item is stored and an upper end thereof is fitted and fixed to a lower end portion of the elastic cylinder portion, and is formed of a synthetic resin or the like. The container body is formed in a bottomed cylindrical shape having an open upper end, and is configured such that the lower end is exposed to the lower end of the case body so that the lower end can be pushed in with the upper end fitted to the lower end of the nozzle member. The lower end of the container body may protrude from the lower end of the case body. However, the support protrusion protrudes from a part of the lower surface of the case body, and the lower surface is set to the same level as the bottom surface of the container body. Thus, the metering distributor can be stably erected.

  Further, in the present invention, by configuring the pushing width of the container body to be substantially constant, it is possible to always discharge a substantially constant amount of liquid. Even if no special means is used for the pushing-in width of the container body, the base end portion of the elastic cylinder portion is fitted and fixed to the upper end portion of the case body, and the gap around the elastic cylinder portion is specified. Although there is no large difference, it is possible to always press with a constant pressing width, but by providing a specific means, it is possible to make the discharge amount each time with less error. As one of the means, a downward stepped portion is provided at a predetermined position inside the case body, and an upward stepped portion is provided at a predetermined position on the outer periphery of the elastic cylinder so that the container body can be pushed to a position where both come into contact with each other. What is necessary is just to comprise.

  As long as the cap covers the discharge nozzle and is detachably mounted, various forms can be adopted, and a cap provided with a rod plug for closing the discharge hole can be preferably used. The cap is also formed of a synthetic resin or the like.

The first means is configured as follows. That is, it has a cylindrical shape with the lower end opened , the flange 3 is extended inward from the upper end edge, the central window hole 4 is opened, and a plurality of longitudinal ribs 6 in the circumferential direction project from the inner peripheral upper end of the peripheral wall 2. The case body A has a cylindrical shape that penetrates and is fixed to the top of the case body A, the discharge nozzle B ₁ is erected above the case body A, and the elastic cylinder portion B ₂ is formed at the upper part inside the case body A. a nozzle member B formed of a material rich in flexibility and elasticity that is vertically, and fitting the upper portion in a liquid-tight manner to the lower end of the elastic tubular portion B _2, capable extraordinary push the bottom to the case body a lower opening A flanged portion 15 of a nozzle member B provided with a bottomed cylindrical container body C and abuttingly locked to the lower surface of the flange 3 is provided, and a plurality of kerfs 16 are formed radially on the outer peripheral edge of the flange portion 15. the fitted non-rotatably to the nozzle member B against casing a by insertion-fitted to each longitudinal rib 6 respectively, the elastic tubular portion B ₂ A vertically extending vertical wall portion 24 is guided to the inner periphery of the case body A through a top plate portion 23 projecting outward from the lower outer periphery, and the upward step portion 25 on the top surface of the top plate portion 23 is the bottom surface of the vertical rib 6. pushing of the container C having a predetermined width until it abuts the downward stepped portion 7 is capable constituted by pushing the container body C was composed as to discharge the stored liquid elastic tubular portion B ₂ is elastically deformed.

  The metering dispenser of the present invention has a simple structure, has a small number of members, is easy to handle, can use almost all of the stored liquid in the container, and after use, only the container is used. Since it is sufficient to replace it, various effects such as being considerably more economical than the conventional product are exhibited.

Further, an upward stepped portion 25 is provided on the outer periphery of the elastic tube portion B ₂ , a downward stepped portion 7 is provided on the inner periphery of the case body A, and a predetermined width until the upward stepped portion 25 comes into contact with the downward stepped portion 7. When the container body C can be pushed in, the pushing width of the container body C is more reliably specified, and therefore the discharge amount due to the integral pushing becomes less varied.

Further, when the vertical wall portion 24 that is guided to the inner periphery of the case body A through the top plate portion 23 projecting outward from the lower outer periphery of the elastic cylinder portion B ₂ is extended, the container body C the indentation for enabling to stably substantially parallel to the casing body a inner surface, can be carried out with a constant vector less constantly variations of press-deformation of the elastic cylindrical portion B _2, as a result, deformation of the elastic tubular portion B ₂ Is always the same deformation, and there is little variation in the discharge amount.

  Further, when the nozzle member B is fitted to the case body A via the rotation preventing means, the nozzle member B is idle even if the cap D is screwed to the nozzle member B. There is no risk of inconvenience such as.
