In the above-mentioned prior art measuring containers, the squeeze operation to the trunk part has a certain operability such that the degree of squeezing varies greatly depending on the person, and the degree of squeezing needs to be adjusted depending on the remaining amount of liquid content. There is a problem that it is difficult to obtain.
In addition, considering the squeeze and elastic resilience, the container body is made of a relatively soft synthetic resin material, and the body is molded into a thin wall. There is also a problem that basic performance such as performance, heat resistance, and appearance shape is impaired. For example, the use of relatively rigid plastic bottles widely used for beverages etc. It is difficult, and restrictions on product design including packaging materials are increased.

  Accordingly, the present invention has an object to create a measuring cap having a squeeze function, and provides a squeeze operability without impairing the function of the container body, and also provides a dispensing container using various variations of the container body. The purpose is to do.

Among the present invention for solving the above technical problems, the means of the invention according to claim 1 is:
In the dispensing container,
A container body that erects the mouth tube portion at the upper end of the body portion;
A cup-shaped metering unit is provided in which a dispensing cylinder is erected through an inner bowl-shaped bottom wall, and the connecting cylinder is suspended from the bottom surface of the weighing unit so as to surround the base end opening of the dispensing cylinder. A measuring cap with a fitting cylinder part hanging down from the lower end of the connecting cylinder part and closely fitted to the mouth cylinder part;
Having a pipe that hangs down inside the container body in a state of being tightly fitted into the dispensing cylinder from below,
Drilling an extraction hole at a predetermined height position of the extraction cylinder;
Drilling a vent in the peripheral wall of the connecting cylinder,

  When the hollow body is squeezed in a state where the fitting cylinder piece is closely fitted to the mouth cylinder portion of the container main body and the measuring cap is attached above the container main body, the connecting cylinder piece is pierced. The inside of the container main body is pressurized through the vent hole provided, and the content liquid ascends the pipe and the dispensing cylinder and flows out from the dispensing hole formed in the dispensing cylinder into the cup-shaped measuring unit.

  When the liquid level in the measuring section reaches the level exceeding the pouring hole, when the squeeze of the hollow body is loosened, the hollow body returns to its original shape due to elastic resilience, so the inside of the container body is in a decompressed state. Thus, the liquid above the lower edge of the pouring hole returns to the inside of the container body through the pouring hole, the pouring cylinder, and the pipe, and as a result, a constant amount of the content liquid can be stored in the measuring unit.

Thus, by adopting a configuration in which the hollow body, which is a separate member, bears squeeze properties, the basic performance of the container body itself, such as rigidity, self-supporting property, heat resistance, and appearance shape, may be impaired. Absent.
On the other hand, without taking into account the basic performance of the container body, fully consider the amount of liquid stored in the weighing unit, change in squeeze operability accompanying changes in the remaining amount of liquid, etc. Since the squeeze characteristics can be set according to the material, capacity, shape, thickness, etc. of the body, it is possible to impart good and stable operability as the squeeze characteristics according to the use mode of the product.

  The height position at which the extraction hole is drilled is a design item that can be determined in consideration of the amount of liquid stored in the measuring section, etc. Although it is possible, considering that the content liquid is ejected to the outside during squeeze, it is preferable that the pouring tube is formed as a top and a pouring hole is formed in the peripheral wall.

It is possible to dispose a hollow body having an easy shape.
In addition, the extending direction of the communicating cylinder piece is a design matter that can be determined in consideration of the moldability, the shape of the hollow body, and the arrangement position.

  According to a fifth aspect of the present invention, in the first, second, third, or fourth aspect of the present invention, a cover material is provided that covers the upper end opening of the measuring portion so as to be freely opened and closed.

  By the said structure of Claim 5, the leakage of a content liquid can be prevented with a cover material, and it can store in comfort.

  According to a sixth aspect of the present invention, in the fifth aspect of the invention, the outer fitting seal cylinder piece is suspended from the bottom surface of the top plate of the lid member, and the outer fitting seal cylinder piece is poured out in the closed state of the lid member. The configuration is to close fit from above the cylinder and close the pouring hole.

According to the above configuration of the sixth aspect, when the lid member is closed, the pouring hole of the pouring tube can be surely sealed, and leakage of the content liquid can be prevented more reliably.
Moreover, since the area | region from the inside of a extraction pipe | tube to the inside of a container main body will be in a sealing state, the squeeze operation by a hollow body cannot be performed, and the misoperation concerning a squeeze operation can be prevented.

  The means of the invention described in claim 7 resides in that, in the invention described in claim 1, 2, 3, 4, 5 or 6, the container body is a plastic bottle.
