Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a liquid dispensing container.

"Problems to be solved by conventional technology and device" As a container for storing a liquid that uses a predetermined amount at a time,
A container with a measuring cup is used. For these, a measuring cup is prepared separately from the container for storing the liquid, and a predetermined amount is weighed from the container to the measuring cup before use.

However, these are cumbersome to use, such as removing the cap of the container body, weighing it in the measuring cup, and then fitting the cap again, and the measuring cup after use should be washed and stored. It must be done and there is a risk of loss, which is inconvenient.

An object of the present invention is to provide a liquid quantitative dispensing container that solves the above-mentioned drawbacks of the prior art.

“Means for Solving the Problem” The container body 2 has a mouth / neck portion 6 standing upright, and a spout member 3 having a lower end fitted to the mouth / neck portion 6 in a liquid-tight manner. , A spout pipe 9 for communicating the inside of the container with the outside of the container,
A communication pipe 10 having one end opened in the container body, and the communication pipe 10
And an air compression device 11 connected to the other end of the
11 is operated by the movement of the weight 16 that can be moved up and down,
The squeezing device 11 acts by the action of the weight 16 that descends when the container body is turned from the upright state to the inverted state, and a certain amount of compressed air is injected from the device 11 into the container body 2 through the communication pipe 10. Is
Along with this, a constant amount of liquid in the container is so constructed as to be discharged from the discharge pipe 9, and a liquid constant-volume dispensing container is characterized.

[Operation] When the container body 2 is turned upside down from the state shown in FIG. 1, the weight 16 descends and presses the air bag 15 downward, so that the compressed air generated inside the container body 2 through the communication pipe 10. Sent to. At this time, the liquid in the container body exists in the opening portion of the communication pipe 10 and the opening portion of the spout pipe 9, but the liquid hardly penetrates into each pipe 19 due to the surface tension of the liquid. Then, a certain amount of the liquid in the container body 2 is poured out to the outside through the pouring pipe 9 by the amount of the air injected into the container body 2.

After pouring out, if the container is returned to the upright state, the weight will return to the original state.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show one embodiment of the present invention.
Denotes a liquid dispensing container. The container 1 is composed of a container body 2 and a spout member 3.

The container body 2 is made of synthetic resin or the like, and has a mouth portion 6 upright from a body portion 4 via a shoulder portion 5.

The spout member 3 is attached to the container body 2 by fitting a fitting cylinder 8 vertically extending from the back surface of the disk-shaped top wall 7 into the inner periphery of the container neck portion 6 in a liquid-tight manner. Further, the lower end of the top wall 7 penetrates through the center front end of the top wall 7 and the lower end of the top wall 7 is suspended in the container body. Further, in the rear portion of the spout pipe 9, similarly, the top wall 7 is penetrated and the lower end is placed in the container body 2.
A communication pipe 10 is provided, which hangs inside and has its upper end erected above the top wall 7. Further, an air compression device 11 is provided upright on the upper surface of the top wall 7 behind the communication pipe 10. The device 11 has a cylindrical casing whose upper and lower surfaces are closed and which is fitted from the rear surface of the top wall 12 of the cylindrical casing.
An air bag 15 is attached by vertically arranging 13 and airtightly fitting the outer circumference of the upper end opening 14 to the inner circumference of the cylinder 13. The air bag 15 has an outer peripheral wall formed in a bellows shape so as to be expandable and contractible, and has a lower end to which a weight 16 which moves up and down in the casing when the container body 2 is erected or inverted is fixed. There is. Further, one end of the communication pipe 10 is airtightly connected to the front part of the fitting cylinder 13. In this air compression device 11, the weight 16 is lowered by moving the container body 2 from the upright state to the inverted state, the air bag 15 is compressed accordingly, and the compressed air inside the bag is transferred from the communication pipe 10 to the inside of the container body 2. Instead of the fixed amount of air that has been poured out and then poured into the container body 2, a fixed amount of liquid passes through the pouring pipe 9 and the container body 2
It is constructed so that it can be poured out.

 It should be noted that reference numeral 7 in FIGS. 1 and 2 denotes an air vent hole.

FIG. 3 shows another embodiment of the present invention. In this embodiment, the pneumatic squeezing device 11 is composed of a cylinder 18 and a piston 19 having a weight 16 incorporated therein.

In addition, in each of the above-mentioned embodiments, it is preferable that all except the weight are made of synthetic resin. Further, the weight may be formed of metal or mineral.

"Effect of the device" As described above, the liquid constant-volume dispensing container of the present invention has the above-described structure, so that a certain amount of liquid can be poured out by a simple operation of changing the container body from the upright state to the inverted state. Because it can be done, it is easy and convenient to use. Further, there is an advantage that the measuring cup is not lost as in the conventional case and the labor for washing the measuring cup can be saved.
