  Hereinafter, a metering dispenser and a metering container equipped with the metering dispenser according to the present invention will be described in detail with reference to the drawings.

  Reference numeral 1 denotes a metering dispenser which is the first embodiment of the present invention. Reference numeral 11 denotes a shell member that forms a filling space S together with a later-described inner plug 12. The shell member 11 has a mounting cylinder 11 a that is mounted on the outer periphery of the mouth 51 of the container body 50. The mounting cylinder 11a is formed with a through hole 11h that locks the convex portion 52 provided on the outer periphery of the mouth portion 51 by hooking.

  A dome portion 11b that bulges upward from the mounting cylinder 11a is formed at the upper end of the mounting cylinder 11a. The dome part 11b allows the filling part S to communicate with the outside world by the cylindrical part 11c rising from its upper end.

  The inner plug 12 is fitted inside the shell member 11 to form a filling space S between the inner plug 12 and the shell member 11.

  On the inner plug 12, a protruding portion 12 b is formed on the inner surface side that forms the filling space S. The protruding portion 12 b rises along the axis O surrounded by an annular recess 12 a that is recessed downward around the axis O.

Between the annular recess 12a and the projection 12b is spaced around the axis O, three through holes A ₁ is formed. As shown in FIG. 3, the through-hole A ₁ supplies the contents from the container body 50 to the filling space S by turning the container body 50 upside down.

  A cylindrical portion 12c that hangs down from the inside of the mouth 51 is integrally provided on the back surface (lower surface) of the inner plug 12 so as to surround the annular recess 12a. Further, an annular seal portion 12d that bulges from a part of the outer surface and holds the inner surface of the mouth portion 51 in a liquid-tight state is integrally provided on the outer surface of the cylindrical portion 12c.

  The movable plug 13 is configured as a hollow cylinder having a through hole formed inside thereof.

  As shown in FIG. 1 and the like, the movable stopper 13 is formed with an annular step 13a that protrudes outward around the axis O on the outer peripheral side thereof. The annular step 13a defines the top dead center of the movable stopper 13 by contacting an annular step 11d formed by recessing the lower end inner edge of the cylindrical portion 11c around the axis O in an annular shape. Thereby, even if the movable plug 13 reaches the top dead center, the movable plug 13 does not fall out of the shell member 11 as shown in FIG.

  Further, as shown in FIG. 1 and the like, the movable stopper 13 is formed with an annular step 13b that protrudes inwardly around the axis O on the inner side. The annular step 13b defines the bottom dead center of the movable stopper 13 by contacting an annular step 12e formed by recessing the outer edge of the protrusion 12b around the axis O in an annular shape. The tip 13e of the movable plug 13 is exposed to the outside through the cylindrical portion 11c of the shell member 11 as shown in FIG. 3 and the like even when the movable plug 13 is at the bottom dead center.

Furthermore, a plurality of through holes A ₂ are formed in the movable stopper 13. The filling space S is communicated with the tip opening A ₃ through these through holes A ₂ . Further, an annular seal portion 13d that slidably contacts the protruding portion 12b is integrally formed on the inner surface of the movable plug 13. The annular seal portion 13d ensures liquid-tightness between the projecting portion 12b and the smooth vertical movement of the movable plug 13 along the projecting portion 12b. Thus, the movable plug 13, among the through holes of the movable plug 13, above the inner surface seal portion 13d, the flow passage r is formed leading to the distal end opening portion A _3.

  An annular seal portion 11e that surrounds the movable stopper 13 and bulges inward is integrally formed on the inner surface of the cylindrical portion 11c. The seal portion 11e is slidably in contact with the movable plug 13, thereby ensuring liquid tightness with the movable plug 13, and also ensuring smooth vertical movement of the movable plug 13 along the cylindrical portion 11c. To do.

In addition, the maximum diameter portion 13f of the movable plug 13, the inner peripheral surface thereof, as shown in FIG. 2 or the like, having a seal portion 13f ₁ projecting annularly around the axis O. As shown in FIG. 3, the seal portion 13f ₁ slidably contacts the inner peripheral side surface 12f ₁ of the annular recess 12a, thereby sealing the through hole A ₁ by pushing the movable plug 13 in a liquid-tight manner. At the same time, a smooth vertical movement of the movable stopper 13 along the inner peripheral side surface 12f ₁ is also ensured.

Similarly, the maximum diameter portion 13f, as shown in FIG. 2 or the like, having its outer peripheral surface the seal portion 13f _2. As shown in FIG. 3, the seal portion 13f ₂ also slidably contacts the outer peripheral side surface 12f ₂ of the annular recess 12a, thereby sealing the through hole A ₁ in a liquid-tight manner by pushing the movable plug 13 in. At the same time, smooth vertical movement of the movable stopper 13 along the outer peripheral side surface 12f ₂ is ensured.

Thus, the movable stopper 13, at a pulling from the shell member 11 through the tubular portion 11c, as shown in FIG. 2, the through hole A the filling space S to open the through-hole A ₁ together providing communication to the container body 50 while closing the _2, in pushing the movable plug 13, as shown in FIG. 1, to open the through hole a ₂ while blocking the filling space S from the container body 50 closes the through-hole a _1.

Reference numeral 14 is an elastic valve formed integrally with the protruding portion 12b. The elastic valve 14 has a valve body 14 a disposed in the flow path r of the movable plug 13. As shown in FIG. 2 and the like, the valve body 14a has a pressing portion 14a ₁ for making contact with the scalp and the like, and a flange portion 14a ₂ formed at the lower end thereof forms an inner diameter edge that forms the tip opening A ₃ 13 g is retained. Incidentally, the valve body 14a, when pushed the movable stopper 13, as shown in FIG. 1 or the like, is exposed from the distal end opening portion A _3.

  Further, as shown in FIG. 2 and the like, the valve body 14a is integrally formed with the protruding portion 12b via a corrugated elastic member 14b. Thereby, the valve body 14a is elastically supported so that a deformation | transformation and restoration | restoration are possible with respect to the protrusion part 12b.

In addition, a plurality of vertical grooves 14a ₃ are formed around the axis O in the pressing portion 14a ₁ . As a result, when the valve body 14a is pushed into the flow path r of the movable stopper 13 against the urging force from the elastic member 14b and the flange portion 14a ₂ is separated from the inner diameter edge portion 13g, FIG. As shown, the contents in the flow path r can be poured out to the outside through a gap between the tip opening A ₃ and the longitudinal groove 14a ₃ . On the contrary, if the pushing of the valve body 14a is released, as shown in FIG. 3A, the flange portion 14a ₂ is seated on the inner diameter edge portion 13g, so that the valve body 14a is urged by the urging force from the elastic member 14b. The tip opening A ₃ is sealed.

In this embodiment, an annular engaging lip (hereinafter referred to as “lip”) 13 h that bulges outward is provided around the distal end opening A ₃ of the movable plug 13.

  Reference numeral 30 in FIG. 1 is an overcap that is detachably screwed into the mouth portion 51 of the container body 50 and that houses the metering dispenser 1 therein. A peripheral wall 31 hangs down from the back surface of the overcap 30, and an inner surface of the peripheral wall 31 projects inwardly around the axis O, and is a locking rib (hereinafter referred to as “rib”) that is detachably fitted to the lip 13h. 32) is formed.

  Thus, when the overcap 30 is attached, as shown in FIG. 1, the rib 32 is engaged with the lip 13 h, so that the movable plug 13 is pushed, while the overcap 30 is removed as shown in FIG. 2. In addition, the movable stopper 13 is pulled out as the rib 32 pulls up the lip 13h.

In addition, when the movable plug 13 is pulled out from the shell member 11 to the maximum (top dead center), the outer peripheral surface of the inclined portion connected to the maximum diameter portion 13f of the movable plug 13 is detachably locked to each other. Te, positioning means L ₁ for positioning the movable plug 13 is provided.

The positioning means L ₁ protrudes from the outer peripheral surface of the movable stopper 13 and is detachably locked to the inner surface of the shell member 11, and a flexible tongue piece 13 L, and a protrusion formed on the inner surface of the shell member 11. The tongue piece 13L is detachably hooked and locked to the projection 11p. The tongue pieces 13L are provided at a plurality of locations (for example, three locations) with an interval around the axis O. Further, the above-described protrusion 11p is not provided, and the tongue piece 13L as described above may be brought into pressure contact with the inner surface of the shell member 11.

  Next, the operation of this embodiment will be described.

  First, when the cap 30 is turned up from the state shown in FIG. 1, the rib 32 of the cap 30 is caught by the lip 13h of the movable plug 13, so that the movable plug 13 is also pulled up together. Since the catch between the rib 32 and the lip 13h is released with a constant force, finally, as shown in FIG. 2, after the movable stopper 13 is pulled up to the top dead center, the cap 30 is the mouth of the container body 50. Deviate from 51.

At this time, the movable plug 13 maintains its position at the top dead center by the tongue piece 13L being hooked and locked on the protrusion 11p. Thus, the movable stopper 13, as shown in FIG. 2, certainly, is positioned the communication hole A ₂ to a position to open the through-hole A ₁ close together between the annular step 11d and 13a. Thereby, if the container main body 50 is inverted so that the front end opening A ₃ of the movable stopper 13 faces downward, the contents of the container main body 50 leak from the front end opening A _{3 in} an unexpected manner. Instead, it is supplied into the filling space S from the mouth 51 through the through hole A ₁ .

Next, if the movable plug 13 is pressed again into the shell member 11 together with the valve body 14a by touching the scalp (surface to be coated) or the like, the tongue piece 13L is deformably deformed and gets over the protrusion 11p. 13 can be pushed. Thus, it becomes a state where the maximum diameter part 13f of movable stoppers 13 is pushed into the annular recess 12a, as shown in FIG. 3 (a), between the through hole A ₁ and filling space S is the maximum diameter although it sealed by part 13f, a through hole a ₂ is communicating the filling space S to the channel r.

That is, when the movable stopper 13 is pushed in, the filling space S cut off from the container body 50 leads to the outside through the flow path r, but the valve body 14a is as shown in FIG. We continue to urge in a direction to seal the distal opening a ₃ by the elastic member 14b. Thereby, even if the movable stopper 13 is pushed in, the tip opening A ₃ is maintained in a sealed state, so that a certain amount of contents can be confined between the filling space S and the flow path r. That is, in the metering and dispensing container of this embodiment, once the movable stopper 13 is pulled out and turned upside down, and then the movable stopper 13 is pushed in again, a certain amount of contents can always be measured and held.

Therefore, after weighing has been completed, in a state pushed the movable plug 13, unless an external force is applied to the valve element 14a, the tip end opening portion A ₃ of the movable plug 13, the elastic valve as shown in FIG. 3 (a) since that will be sealed at 14, after which pushed the movable plug 13, inadvertently, metered contents are never as scattering from the tip spout a _3.

  Therefore, when the contents are poured out, as shown in FIG. 3 (b), if the valve element 14a protruding from the movable stopper 13 is pressed against the portion to be poured out (surface to be coated) such as the scalp, the measurement is performed. The used contents can be dispensed by an amount corresponding to the pushing time.

  As described above, according to the present embodiment, when the movable plug 13 is pulled out from the shell member 11 to the maximum, the movable plug 13 can be positioned as it is. That is, according to this embodiment, as long as the movable stopper 13 is pulled out to the maximum, the state where the movable stopper 13 is pulled out to the maximum can be maintained.

  Therefore, for example, if the movable stopper 13 is not pulled out to the maximum, even if the inside of the container body 50 and the filling space S lead to the outside through the movable stopper 13, if the movable stopper 13 is pulled out to the maximum, In addition, the contents do not leak to the outside through the movable stopper 13. That is, according to this embodiment, it is possible to prevent an unexpected leak during operation.

Further, if the positioning means L ₁ is a flexible tongue piece 13L that protrudes from the outer surface of the movable stopper 13 and is detachably locked to the inner surface of the shell member 11, it can be locked relatively smoothly. In operation, the movable stopper 13 can be positioned.

  According to the present invention, the tongue piece 13L is formed with a projection 11p on the inner surface of the shell member 11 as in this embodiment, so that the tongue piece 13L is engaged with the projection 11p, and a recess is formed in place of the projection 11p. By forming, what is latched by the said recessed part, or what is hooked directly on the inner surface of the shell member 11 and latched by the shell member is also included.

  4 to 6 are each a second form of a metering container according to the present invention. In this embodiment, the same parts as those in the first embodiment have the same reference numerals, and the description thereof is omitted.

In the metering dispenser 2 of this embodiment, when the movable plug 13 is pulled out from the shell member 11 to the maximum (top dead center), it is detachably locked to the outer peripheral surface of the movable plug 13 (maximum diameter portion 13f). Thus, positioning means L ₂ for positioning the movable stopper 13 is provided.

The positioning means L ₂ hangs down from the inner surface of the shell member 11 and is detachably hooked to the outer peripheral surface of the movable plug 13 and locked on the outer peripheral surface of the movable plug 13. It is comprised by the formed protrusion 13p, and it is comprised so that the recessed part 11n formed in the leg part 11L may be hooked on the protrusion 13p so that attachment or detachment is possible. Moreover, you may comprise so that the inner surface of the leg part 11L may press-contact with the outer peripheral surface of a movable stopper, without forming the above protrusion 13p and the recessed part 11n. Also in this case, the leg portions 11L are provided at a plurality of locations (for example, 3 locations) at intervals around the axis O.

As in the present embodiment, the positioning means L ₂ is suspended from the inner surface of the shell member 11, and the flexible leg portion 11 L that is detachably locked to the outer peripheral surface of the movable plug 13 is relatively smooth. The positioning of the movable stopper 13 can be realized by a simple locking operation.

  According to the present invention, the leg portion 11L is movable in place of the recess portion 11n in addition to the recess portion 11n so as to lock the projection 13p formed on the outer peripheral surface of the movable plug 13 as in this embodiment. The thing provided with the processus | protrusion so that the recessed part formed in the outer surface of the stopper 13 may be latched, or the thing which hooks directly on the outer peripheral surface of the movable stopper 13 and latches the said movable stopper is included.

  The above description shows only one embodiment of the present invention, and various modifications can be made within the scope of the claims. For example, the external shape of the movable stopper may be a square shape instead of the cylindrical shape as in the present embodiment.
