Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a liquid metering dispenser.

“Problems to be solved by the conventional technology and device” Conventionally, a measuring cup is used to separate the liquid contained in the bottle. For example, concentrated juice, concentrated coffee, etc. are weighed out into a measuring cup, poured into a beverage container, and then diluted with a diluting solution before use. There is also the trouble of having to wash the measuring cup every time.

The present invention has been made in view of the above points, and an object of the present invention is to provide a liquid metered-dose dispenser capable of dispensing a fixed amount by an extremely simple operation.

"Means for Solving the Problem" Body part 5 formed by extending top wall 4 from peripheral wall 3 standing from outer peripheral edge of bottom wall 2 and top wall 4 and body part 5 penetrating through top wall 4 of the body part
A cylinder 6 having a bottom and an open upper surface, in which a lower end is hung inside and an upper end is projected above the top wall 4, and is hung below an outer peripheral edge of a through hole formed in the body bottom wall 2. The guide cylinder portion 7 having an open lower surface, the annular piston 8 that slides up and down in the cylinder 6, the upper end is fitted to the lower end of the piston 8, and the bottom wall 10 of the cylinder 6 is liquid-tightly penetrated. And a movable cylinder 9 which is liquid-tightly penetrated through the guide cylinder portion 7 and which is vertically movably mounted so as to be movable up and down. A first communication hole 12 that communicates with the inside of the portion 5 is formed, and a second communication hole 13 that is closed by the guide cylinder portion 7 when the piston descends the most is provided in the peripheral wall of the movable cylinder 9 to raise the movable cylinder 9. The piston 8 rises above the first communication hole 12 to block the flow in the cylinder 6 and the body 5. After, it was composed as the second communication hole 13 is opened to the barrel 5.

[Operation] When the movable cylinder 9 is pushed up from the state shown in FIG. 2a, the piston 8 rises in the cylinder 6 and passes through the first communication hole 12 to block the flow between the cylinder 6 and the body portion 5. When done,
A second communication hole 13 opens into the body portion 5, and as shown in FIG. 2B, passes through the second communication hole 13 into the movable cylinder 9, and a fixed amount of liquid in the body portion 5 from the lower end opening of the movable cylinder 9. Is poured out.

After pouring out, when the movable cylinder 9 is lowered, the second communication hole 13 becomes the guide cylinder portion 7.
After being closed by, the first communication hole 12 is opened, and the liquid in the bottle 14 is filled in the body portion 5 through the inside of the cylinder 6.

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

In FIG. 1, reference numeral 1 indicates a liquid metering dispenser. The dispenser 1 has a cylindrical body portion 5 in which a top wall 4 extends from an upper end edge of a peripheral wall 3 standing from the outer peripheral edge of a disk-shaped bottom wall 2. In addition, the body portion 5 has a bottomed, cylindrical cylinder with an open upper surface, which penetrates through the center of the top wall 4 and hangs a lower end inside the body portion 5 and an upper end standing above the top wall. 6 is provided. Further, a cylindrical guide cylinder portion 7 having an open lower surface is vertically provided below an outer peripheral edge of a through hole formed in the center of the bottom wall 2 of the body portion 5.

An annular piston 8 which slides up and down in the cylinder 6 is provided, and the lower end of the piston 8 is fitted with the upper end of a movable cylinder 9. The movable cylinder 9 has a cylindrical shape with an open lower surface, and penetrates a through hole formed in the center of the bottom wall 10 of the cylinder 6 in a liquid-tight manner,
Moreover, the guide cylinder portion 7 is mounted so as to be liquid-tight and capable of moving up and down. Further, on the outer periphery of the lower part of the guide cylinder 9, a flange portion 11 for limiting the rise of the movable cylinder 9 is provided so as to project. The piston 8 in the cylinder 6 is configured to rise by raising the movable barrel 9.

Further, a first communication hole 12 is formed in the lower peripheral wall of the cylinder 6 which is vertically provided in the body portion 5. When the piston 8 in the cylinder 6 is at the lowest position, the first communication hole 12 is located above the piston 8 and communicates the inside of the cylinder 6 with the inside of the body portion 5. It is configured such that when it rises up, the flow in the cylinder 6 and the flow in the body 5 are blocked. The number of the first communication holes 12 may be one, but it is preferable to provide a plurality of the first communication holes 12 in order to improve the gas / liquid exchange between the body portion 5 and the cylinder 6.

Further, a second communication hole 13 is also formed in the peripheral wall of the movable cylinder 9. The second communication hole 13 is provided in the guide tube portion 7 when the piston is at the lowest position.
The movable cylinder 9 is raised to block the flow between the cylinder 6 and the body 5 by the piston 8 and then opened in the body 5.
Like the first communication hole 12, the second communication hole 13 may be one, but it is preferable that a plurality of second communication holes 13 be provided.

As shown in FIG. 2, the liquid fixed amount dispenser 1 configured as described above is configured to be used by being fitted and mounted in a liquid tight manner on the inner periphery of the outlet 15 of the inverted liquid bottle 14.

The dispenser 1 can be made of synthetic resin.

"Effect of the Invention" As described above, the liquid constant-volume dispenser of the present invention can dispense a fixed amount of liquid by an extremely simple operation of pushing up the movable cylinder and can be moved by the structure described above. Even if the cylinder may rotate with respect to the body, it is possible to always dispense a good fixed amount of liquid regardless of the liquid dispensing operation, and furthermore, the liquid bottle is fixed upside down. If this is done, the liquid will always flow out immediately below, so that when the liquid is weighed out, there is little risk of the liquid splashing out of the container for weighing out, and the like.
Further, the number of constituent members is small, and it has an advantage that it can be easily manufactured at low cost.
