Description

[Detailed description of the invention] <Industrial application field> The present invention relates to an inner stopper, and more specifically, to a container body made of flexible and elastic plastic, and for fitting the inner stopper onto the main body. This invention relates to an inner stopper used in a container, which is comprised of a measuring part provided through a narrow part of the container body, and a pipe communicating from the lower end of the container main body to the measuring part.

<Prior Art> A conventionally used container with a measuring section is composed of a container body 1, a measuring section 2, an inner stopper 5, and a pipe 3, as shown in FIG.
By pressurizing the body part of the container body 1, the contents flow into the measuring part 2 through the pipe 3, and when a predetermined amount of the contents has flowed into the measuring part 2, the pressurization is stopped, and the container is tilted and measured. The contents section in section 2 is taken out.

<Problem to be solved by the invention> However, after weighing the contents in the container,
When taking out the contents from the measuring section 2 to the outside, if the pipe 3 is not taken out with the part that opens into the measuring section 2 facing upward, a part of the contents inside the measuring section will pass through the pipe 3 into the container body 1. It flows backwards into the
Accurate measurement was not possible. In addition, when the container that has been deformed during measurement returns to its original shape, air suddenly moves in and out between the container body 1, the pipe 3, and the measuring section 2, causing unpleasant dullness.

In order to solve these problems, a valve equipped with an air hole with an area the same as or slightly larger than the opening of the pipe is installed in the lightweight part via an elastic arm so that the opening of the pipe can be opened and closed. is possible. When the container body is pressurized, the valve opens, allowing the contents to move. When the pressure is stopped, the valve closes due to the reduced pressure within the container body, preventing the contents from moving in and out and preventing air from entering and exiting rapidly. However, there was a problem in that if the valve came into contact with the opening in a misaligned state, the opening could not be completely closed.

<Means for Solving the Problems> The present invention was made to solve the above problems, and includes a container body made of flexible and elastic plastic, and a narrow portion for fitting an inner stopper onto the body. An inner stopper for use in a container consisting of a measuring part provided through a pipe, and a pipe communicating from the lower end of the body of the container body to the measuring part. A valve having an air hole is connected horizontally to the inner plug, and the shape of the valve is such that the upper end has a diameter larger than the inner diameter of the pipe and the lower end has a diameter larger than the inner diameter of the pipe. is an inverted truncated cone having a diameter smaller than the inner diameter of the pipe.

<Function> The present invention has the above-mentioned configuration, and the valve closes the opening on the measuring section side of the pipe to prevent the contents from flowing back inside the measuring section, and allows the deformed container to return to its original shape. To prevent air from suddenly flowing in and out between the container body, pipe, and measuring section.

<Example> The inner stopper of the present invention will be explained in detail using the drawings.

FIG. 1 is a perspective view of the inner stopper 6 of the present invention, and FIG. 2 is an explanatory diagram showing the state in which the inner stopper 6 is set between the container body 1 and the measuring part 2. It consists of a main body 7, a valve 8, and a thin and highly elastic arm 9, and the valve 8 is provided with a small air hole 10.

When setting the inner stopper 6 between the container body 1 and the measuring section 2 as shown in FIG. 2, the valve 8 is set so as to be aligned with the opening of the pipe 3.

Next, the behavior of each part when measuring the contents inside the container body will be explained.

First, when the body portion of the container body 1 is pressurized, the contents rise up the pipe 3, displace the valve 8, and flow into the measuring section 2, as shown in FIG. When pressurization is stopped when a predetermined amount of contents has flowed into the measuring section 2 according to a scale (not shown) provided on the measuring section 2, the fourth
As shown in the figure, the valve 8 closes the opening of the pipe 3 so that the pressure inside the container body is reduced. At this time,
It is believed that the elasticity of the arm 9 also assists in the closing movement of the valve 8. Furthermore, even if the valve 8 does not exactly match the opening of the pipe 3 and contacts with a slight deviation, the diameter of the tip of the valve 8 is smaller than the inner diameter of the pipe 3, and the shape of the valve 8 is conical. Since it is a base, the valve 8 can easily close the opening of the pipe 3 accurately.

After closing, air flows into the pipe 3 through the small air hole 10 provided in the valve 8, and the container body 1 returns to its original shape.

<Effects of the invention> The inner stopper of the present invention has the above-mentioned structure, and even when the pipe side is turned downward when taking out the contents, the valve prevents the contents from flowing back. , accurate measurement is possible. Further, since the valve prevents air from rapidly entering and exiting between the container body, the pipe, and the measuring section, which occurs when the container deformed during measurement returns to its original shape, there is no unpleasant dullness caused by this. Moreover, even if the valve does not exactly match the opening of the pipe, since the valve has a truncated conical shape, it can be easily inserted into the opening of the pipe and can be closed reliably.
