The spout nozzle is erected, a regulating cylinder that communicates with the spout nozzle and forms a liquid flow path is vertically installed on the inner surface of the top wall, and screwed into a screw engraved at the container opening on the inner periphery of the side cylinder wall. Screws are engraved, the opening / closing lid is provided with a stopper that seals the discharge port on the inner surface, and the regulating cylinder is formed on the cylinder end face from a dividing line that divides the circumference at equal intervals. A protruding surface extending in the axial direction, and engraved on the inner periphery of the side cylinder wall of the cap base from a pointed edge of the protruding surface. To adopt a structure which is characterized in that it has a plurality of restricting end comprising a tapered surface extending helically in the same helical direction and di.

[0006]

Next, embodiments of the present invention will be described with reference to the drawings. The dispensing container of the present invention is used as a dispensing container for cosmetics, hair dye, correction liquid, and the like, and contains a plurality of types of content liquids having different specific gravities. In FIG. 1, A is a container body molded of a flexible synthetic resin, B is a cap molded of a synthetic resin, and is a cap base B1 and an opening and closing attached to the cap base B1 by a hinge B3. And a lid B2.

[0007] The container body A has a mouth 1 and a body 2, and a screw 3 is engraved on the outer periphery of the mouth 1. In the container body A, a ball 4 (see FIG. 4) for mixing and stirring a plurality of content liquids is accommodated.

As shown in FIG. 2, the cap base B1 is
It comprises a top wall 5 and a side wall 6. At the center of the top wall 5, an ejection nozzle 7 is provided upright, and the ejection nozzle 7 is provided with a discharge port 8. On the lower surface of the top wall 5, a regulating cylinder 9 having an inner periphery continuous with the inner periphery of the pouring nozzle 7 and forming a liquid flow path is vertically provided.
Restriction ends 10a and 10b for restricting the movement of the ball 4 are formed.

As shown in FIG. 3, the regulating ends 10a, 10b
Is formed by bisecting the cylinder end circumference and extending in the axial direction from the dividing line, and is formed on the inner periphery of the side cylinder wall 6 of the cap base body B1 from the sharp edges of the projection surfaces 11a, b. The tapered surfaces 12a and 12b spirally extend in the same spiral direction as the screws. The side surface of the regulating cylinder 9 formed by the tapered surfaces 12a and 12b of the regulating end 10 and the opening 1 on the inner periphery of the regulating cylinder 9.
3, the liquid inlet X to the pouring nozzle 7 is formed.

As shown in FIG. 2, a sealing ring 14 fitted on the inner periphery of the mouth 1 of the container body A is provided around the lower surface of the top wall 5.
Is hanging. At predetermined positions on the top surface of the top wall 5, connecting pieces 15a and 15b connected to the opening / closing lid B2 to form hinges B3.
A swelling ring 16 protruding outward is provided at the peripheral edge of the upper end except for the connecting pieces 15a and 15b.
A fitting portion of the opening / closing lid B2 is formed together with the upper end surface.
A notch 17 is formed on the outer peripheral surface of the side cylinder wall 6 between the connecting pieces 15a and 15b, and a concave portion 18 is provided on the outer peripheral surface of the side cylinder wall 6 opposite to the notch 17. A screw 19 that is screwed into the screw 3 formed on the outer periphery of the container opening 1 is formed in an upper portion of the inner periphery of the side wall 6.

The opening / closing lid B2 has a dome-shaped top wall 20 and a fitting ring 21 provided on a peripheral edge of the top wall 20 except for the connecting piece 15 of the hinge B3. At the center of the inner surface of the top wall 20, a stopper 22 for sealing the discharge port 8 of the injection nozzle 7 when the lid is closed is erected, and a protruding ring 23 surrounding the stopper 22 is erected on the outer periphery of the stopper 22. Has been established. On the opposite side of the hinge B3 of the fitting ring 21, a knob 24 is provided to facilitate opening and closing operations of the opening and closing cover B2.

The hinge B3 is a so-called three-point hinge, and a recess 25 is provided in the middle of the connecting pieces 15a and 15b so that the connecting piece 15 can be bent and restored.
A notch 26 is provided in the top wall 20 of the opening / closing lid B2, and an end of the notch 26 and the notch 17 of the cap base B1.
A pressing piece 27 is continuously provided between the lower end of the holding member 27 and the holding member 27.

Next, based on the structure of the present invention,
The operation and effect will be described. In use, when the dispensing container is shaken up and down, the ball 4 moves up and down, whereby a plurality of types of content liquids having different specific gravities are stirred and mixed. When the container body 2 is pressed, the mixed content solution is discharged. 7 is discharged.

As shown in FIG. 4, when the dispensing container is ejected upside down, the ball 4 is attached to the regulating cylinder 9 and the sealing ring 1.
4 and does not block the liquid inlet X to the discharge nozzle 7 of the regulating cylinder 9. Even if the ball 4 falls to the center of the opening 13 of the regulating cylinder 9, it is guided along the tapered surface 12 from the pointed edge of the protruding surface 11 of one of the regulating ends 10 a and b, and regulated at the bottom end of the tapered surface 12. It does not fall off from the end portions 10a and 10b and falls between the outer periphery of the control cylinder 9 and the top wall 5 and the sealing ring 14, and does not block the opening 13 of the control cylinder 9.

In forming the cap B, the regulating ends 10a, b of the regulating cylinder 9 are tapered.
However, because the tapered surface 12 extends in the same direction as the screw 19 of the cap base B1, the cap B can be easily removed together with the threaded portion of the cap base B1 when removing the cap B from the mold.

In the above embodiment, screws are screwed into the outer periphery of the container mouth and the inner periphery of the side cylinder wall of the cap base, but fitting protrusions are formed on the outer periphery of the container mouth and the side cylinder wall. Alternatively, the cap may be fitted to the container mouth by plugging it. Further, although the cap opening / closing lid is attached to the cap base so that it can be opened and closed by a hinge, the opening / closing lid may be separately put as a lid.

[0017]

Since the present invention is configured as described above, it has the following effects. Since the pouring nozzle is erected on the cap base, the cap and the pouring nozzle can be integrally molded, and there is no need to attach the pouring nozzle to the container opening. it can.

Since the regulating end is provided on the end face of the regulating cylinder following the pouring nozzle, the ball does not block the opening of the regulating cylinder when the pouring container is inverted, and the tapered surface is the same as the screw of the cap base. The spiral surface in the direction makes it easy to remove the mold during molding.
