Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a stopper attached to an opening of a container for quantitatively discharging the contents in the container by a simple operation.

[Prior Art] An example of a stopper for discharging the contents quantitatively by tilting the container is disclosed in Japanese Utility Model Laid-Open No. 58-101133. That is, as shown in FIG. 4, a fixed portion (3) including a cylindrical wall (31) having an inflow port a at the lower end and an annular stopper (32) connected to the lower end of the outer cylindrical wall (31).
3) and a front lid part (3) movable in the cylindrical wall (31).
4) and a collar (35) on the other end of the front lid (34),
A movable part (39) consisting of an annular convex portion (36) at a specific position and a conduit (38) having a small hole (37) between them, and a movable rear plate (). Four
0) is movably attached.

In this way, the front lid part (34) movable in the cylindrical wall (31)
And a movable part (39) having the above-mentioned structure. When tilted, a fixed amount is discharged by discharging only the amount of movement of the front lid part (34). When tilted, the cylindrical wall (31) The discharge part (43) of () was generally configured as follows. That is, as shown in FIG.
The discharge part (43) of 1) has an outer peripheral wall (41) larger than the outer diameter of the front lid part (34), and inside the peripheral wall (41) is approximately equal to or larger than the outer diameter of the front lid part (34). A large inner peripheral wall (42) is provided, the outer peripheral wall (41) is continuous over the entire circumference, and the inner peripheral wall (42) is partially provided, and the movable part (39) is the most advanced. When the front lid (34) is moved to a position where the tip of the front lid (34) does not reach the tip of the cylindrical wall (31), and when the outer diameter of the front lid (34) and the inner peripheral wall (42) are substantially the same, the lower end is The structure is such that it stops at a position ahead of the lower end of the inner peripheral wall (42).

[Problems to be solved by the present invention]

A movable part (39) is formed inside the cylindrical wall (31) fixed as described above.
When the contents are discharged by using a stopper having a structure in which the discharge portion (43) of the cylindrical wall (31) is provided with the outer peripheral wall (41) and the inner peripheral wall (42), the outer peripheral wall ( 41) and the inner peripheral wall (42) are left with contents, which may contaminate the discharge part (43) of the stopper, or the contents left behind during the next discharge may unexpectedly drop and contaminate the floor or equipment. there were.

The present invention eliminates such drawbacks, and even with the above-described stopper, the contents can be smoothly discharged, and the contents are not left in the discharging portion and the stopper and the floor are not contaminated. Intended to provide the body.

[Means for solving problems]

The present invention provides a movable part having a cylindrical wall partially having an inflow port and a front air intake port that moves a certain distance by tilting a container in the cylindrical wall at the rear side to close the inflow port and a small port. In the fixed amount stopper body, the discharge portion above the cylindrical wall is provided with an inner peripheral wall that is substantially equal to or larger than the outer diameter of the front lid portion and an outer peripheral wall that is larger than the outer diameter of the front lid portion, It is a quantitative stopper characterized in that it is made continuous by a connecting wall.

[Action]

Since the outer peripheral wall and the inner peripheral wall of the cylindrical wall are alternately provided in a continuous manner, when the container is tilted, the front lid part of the movable part smoothly moves along the inner peripheral wall in the discharging part. Also, the contents accumulated in the gap between the cylinder wall and the front lid due to the movement of the front cover are discharged from the gap between the outer peripheral wall and the front cover, and after the discharge is completed, the contents do not remain in the discharge unit and remain in the cylinder wall. Return downwards along.

〔Example〕

The metering plug A of the present invention has a fixing part (1) as shown in FIG.
And a movable part (2) and a closing part (3). The fixing part (1) is formed by connecting a fitting wall (5) fixed to the container B and a discharge part (6) forming the discharge port X to a single cylindrical wall (4) communicating from the inside to the outside of the container B. An annular stopper (7) is provided at the lower end of the cylindrical wall (4) inside the container B, and an inner peripheral wall (8) and an outer peripheral wall (9) are alternately provided at the upper end. A discharge portion (6) which is continuous with the outer peripheral wall (9) by a connecting wall (10) is provided, and an inflow port a is formed by the peripheral edge of the annular stopper (7).

The movable part (2) is a front cover part (1) that moves inside the cylindrical wall (4).
The conduit (13) is connected to 2), and the front cover (1)
In 2), a standing wall (15) is connected to the circumferential edge of the front plate (14), and an air intake small hole b communicating with the conduit (13) and an air intake small hole c in the conduit (13) are formed in the center. Are formed.

The closing part (3) is swingably provided at the lower end of the conduit (13) of the movable part (2), and specifically, the connecting part (16) having a structure that does not come off from the lower end of the conduit (13), Below the connecting portion (16), the skirt wall (1
7), an annular flange portion (18) extends horizontally from the lower end of the skirt wall (17).

Then, as shown in FIG. 3, when the container B is tilted and the contents are discharged, the lid portion (12) advances toward the discharging portion (6), and the front lid portion (12), the cylindrical wall (4) and the annular shape. When the contents enter the weighing section surrounded by the stopper (7) and the tip of the front lid section (12) slightly reaches the discharge section (6), the content is discharged from the discharge port X. It At this time, the flange portion (18) of the closing portion (3) abuts the annular stopper (7) to close the inflow port a.

When the vertical state is restored after the discharge, the air in the small hole b container B of the front lid part (12) is discharged to the outside, and the movable part (2) quickly returns to the original lowest position and at the same time, the discharge is performed. Division (6)
The contents left behind are also returned from the discharge section (6) through the cylindrical wall (4).

〔effect〕

As described above, the metering plug according to the present invention has a structure in which the movable part moves while measuring the contents in the cylinder wall, and the structure does not leave the contents in the discharge part, so that the cap and hands are not soiled. The discharge can be repeated. Therefore, even a liquid having a high viscosity such as a liquid detergent can be discharged without being contaminated.
