Abstract

PROBLEM TO BE SOLVED: To prevent a liquid material in a suction pipe from being discharged by a method wherein a spring on-off valve having a stopper to close a liquid spout port in the bottom of a measuring cap is supported on a cylindrical part that is continuously formed from the liquid spout port. SOLUTION: When a container main body 1 is pressed in the middle, a content A rises from the bottom of a pipe 10 and enters a cylindrical part 9 after passing through an opening of a support ring 20 that is a component of a spring on-off valve 22. Then, when the content A passes along a spring 19, it pushes a stopper 18 up using the elastic property of the spring 19 to form a gap between the stopper 18 and a liquid spout port 8 provided in a bottom 7. The content A flows into a measuring chamber 3 through the gap, and when a specified amount of the content A is fed and pressing of the container main body is stopped, the stopper 18 seals up the liquid spout port 8 by the elastic force of the springs 19, with the specified amount of the content A left in the measuring chamber 3. Thereby, only the content A in the measuring chamber 3 can be discharged outside.

However, in the above-mentioned container with a liquid measuring cap having the squeeze structure,
It has the advantage of being relatively simple in structure and operation,
A suction pipe hangs down from the measuring cup to the bottom of the container body, and this suction pipe contains the liquid material at the same level as the liquid material in the container body. When pouring out the liquid substance, there is a problem that the liquid substance in the suction pipe is also poured out. Moreover, since the liquid amount in the suction pipe changes according to the change in the liquid amount in the container, the liquid amount in the suction pipe is overlaid on the measured liquid substance. As a result, there is a problem in that the amount of liquid poured out to the outside varies. Therefore, the present invention provides a highly reliable container with a liquid measuring cap in which the liquid substance in the suction pipe is not poured out to the outside, and the amount of the liquid poured out is always kept constant to prevent variations. That is.

For example, it can be manufactured by molding using a resin such as polyethylene, polypropylene, polystyrene, polycarbonate, polyamide, polyester, polyvinyl chloride, etc. by a molding method such as injection molding or extrusion molding.

Regarding the container with a liquid measuring cap having the above-mentioned structure, the mechanism for pouring out the contents thereof will be described. First, the container body 1 in the state shown in FIG.
When the central portion of the is squeezed, the content A is pressed and rises from the bottom of the pipe portion 10 to pass through the tubular portion 9 and, at that time, constitutes the spring opening / closing valve 22. The support ring 20 is a support ring receiving portion 2 provided on the tubular portion 9.
While being supported by 7, the contents A pass through the space portion and further between the spring portions 19, the spring elastic force of the spring portions 19 is used to push up the honey plug 18 upward to provide the bottom portion 7. A space is formed between the liquid outlet 8 and the honey plug 18, and the content A is poured into the measuring chamber 3 from the space portion. In the above, when the central part of the container body 1 is squeezed, the air in the container body 1 is compressed into the flat closed top part 1 described above.
6 is evacuated from the air hole 17 provided in 6 and the contents A are weighed in the measuring chamber 3
It may be difficult to pour it into the bottom 7
This can be prevented by adjusting the size of the hole of the liquid outlet port 8 provided in the above and the size of the hole of the air hole 17 provided in the flat closed top 16 described above. For example, the diameter of the hole of the liquid outlet 8 provided on the bottom 7 and the flat closed top 1
The diameters of the air holes 17 provided in No. 6 are in the relation of about 7: 1 to 10: 1 and the liquid outlets 8 respectively.
By providing the holes of the air holes 17, an appropriate amount of the content A can be poured into the measuring chamber 3. Specifically, when the container body 1 is held by hand and squeezed by the force of the hand, the diameter of the hole of the liquid outlet 8 provided in the bottom portion 7 is 7 mm to 10 m.
It is preferable that the diameter of the air hole 17 is 1 mm with respect to m. Thus, when a predetermined amount of the content A is poured into the measuring chamber 3, the squeezing is stopped, and at that time, the honey plug 18 that constitutes the spring-type on-off valve 22 has the spring elastic force of the spring portion 19. Is opened to fit into the liquid outlet 8 of the bottom portion 7 to close the liquid outlet 8, whereby a certain amount of the content A is measured and stored in the measuring chamber 3. And
When the content A is poured out to the outside while the container body 1 is laid sideways, the liquid outlet 8 of the bottom portion 7 is sealed by the plug 18 that constitutes the spring-type on-off valve 22, and further constitutes the spring-type on-off valve 22. Since the support ring 20 is supported by the support ring receiving portion 27 provided on the tubular portion 9,
Since it is fixed to the liquid outlet 8 of the bottom 7, only the contents A in the measuring chamber 3 can be poured out to the outside, and air can be blown into the container body 1 from the air hole 17. become. Next, after all the contents A have been poured out to the outside, the container book 1 is re-standing and straightened, and the hinge lid 4 is sealed, and in use thereof, the hinge lid 4 is opened and the above-mentioned is again performed. By repeating the same operation as above, a certain amount of contents A can be
It can be poured out with high accuracy.
