DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a metering discharge container.

[0002]

2. Description of the Related Art As described in Japanese Patent Application Laid-Open No. Hei 10-24950, a fixed-quantity discharge container quantifies the discharge amount of an internal solution by regulating a squeeze deformation amount of a pressing operation portion provided on a container body. ing.

[0003]

In a conventional fixed-rate discharge container, an oil which combines with oxygen in the container with time and oxidizes, or a high-temperature filled liquid which contracts at a low temperature with time is used. When the pressure in the container is reduced by the contents of the container, the pressing operation portion is squeezed and deformed for a long time by the depressurizing force. The pressing operation portion that has undergone plastic deformation cannot secure a constant squeeze deformation amount, and the ejection amount varies.

[0004] When the pressing operation portion of the container body is made of a hard material that does not squeeze due to the depressurizing force of the internal pressure of the container, the pressing operation for discharging cannot be performed.

An object of the present invention is to stably quantify a discharge amount without plastically deforming a pressing operation portion by a pressure reducing pressure of a container internal pressure.

[0006]

According to the present invention, there is provided a fixed-rate discharge container in which a squeezing deformation of a pressing operation portion provided on a container body is regulated to a constant value, wherein the container is other than the pressing operation portion of the container body. Is provided with a decompression deformable portion, so that an internal solution for reducing the pressure inside the container with time can be accommodated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a fixed-rate discharge container 10 has a cap 12 fitted in an opening of a squeezable deformable container body 11 made of a soft plastic, and a spout (not shown) of the cap 12 is inserted. The upper lid 13 can be opened and closed.

In the constant-rate discharge container 10, the upper body 11A including the depressed pressing operation portions 14 provided on both sides of the container body 11 has an elliptical or circular cross-sectional shape, and the rigidity of the pressing operation portion 14 is reduced. Pressing was made easier (Fig. 2). The container body 11
Inside, a perforated cylinder 15 suspended from the cap 12 is arranged at a position facing the pressing operation unit 14. Perforated cylinder 1
5 abuts against the pressed pressing operation unit 14 while forming a flow path of the internal solution from the inside of the container body 11 to the spout of the cap 12, and regulates the amount of squeezing deformation of the pressing operation unit 14 to be constant. I do. Therefore, when the upper lid 13 is opened and the container main body 11 is inverted, the discharge amount of the internal solution can be quantified by pressing the pressing operation portion 14 until it abuts on the perforated cylinder 15.

The metering discharge container 10 has a portion other than the pressing operation portion 14 of the container body 11, specifically, a lower body 11 having the same cross-sectional shape or a different cross-sectional shape as the upper body 11A.
B is provided with a number of decompression deformation portions 16 (FIGS. 1 and 3),
Alternatively, it is possible to store a liquid content such as a liquid filled at a high temperature, which reduces the internal pressure of the container over time.

The decompression deforming portion 16 is formed of a convex rib whose entire circumference is surrounded by the thin portion 16A, and is deformed into a concave shape by the decompression force F of the container internal pressure (FIG. 4). The thickness of the thin portion 16A is
It is thinnest as compared with the thickness of the other parts of the container body 1. Container 1
The number of the reduced pressure deforming portions 16 at 0 (the number of ribs) is
It is determined based on the magnitude of the pressure reduction amount of the container internal pressure that is expected according to the internal solution.

Therefore, according to the present embodiment, the following operations are provided. When the internal pressure of the container is reduced over time by the contents, the reduced pressure deforming portion 16 formed of the thin portion is positively deformed by the reduced pressure force, and the pressing operation portion 14 is prevented from being squeezed by the reduced pressure force. Accordingly, the pressing operation unit 14 can stably maintain a constant squeeze deformation amount for a long period of time without plastic deformation, and can stably quantify the discharge amount.

According to the present invention, the thickness distribution of a portion other than the pressing operation portion of the container body may be adjusted, and a reduced pressure deforming portion composed of a flat thin portion may be provided.

[0013]

As described above, according to the present invention, the pressing operation portion is not plastically deformed by the pressure reduction of the container internal pressure.
The discharge amount can be quantified stably.
