Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a container with a liquid dispenser for measuring and distributing a mouthwash, a syrup and the like in fixed amounts.

"Prior Art" As a container with the above liquid metering dispenser, for example
The device of Japanese Patent No. 93046 is known. The container with a dispenser is provided with a fitting cylinder that is fitted from the lower surface of the top plate that closes the upper end surface of the mouth neck portion of the container body to the inner surface of the mouth neck portion, and has a semicircular hole in the front portion of the arbitrarily determined top plate. , A first member having its curved edge located at the front side and having a partition plate extending downward from the straight partial hole edge of the semi-circular hole, and the upper end cylinder part fitted to the inner surface of the fitting cylinder. And a second member having a bottomed cylindrical shape, the second member including a second half portion excluding an upper portion from a lower end of an upper cylindrical portion fitted to the fitting cylinder to a slanting inward direction. 1 slanted plate, and further a second slanted plate from the lower end of the plate to the slanted front side through the first hanging plate,
Respectively protruding, the second hanging plate is hung again from the lower end of the second inclined plate to make the lower end of the second hanging plate continuous with the second member bottom plate, and the liquid inflow hole is formed in the first inclined plate. An air hole is formed in the second inclined plate, an air pipe is erected from the peripheral edge of the hole, and a gap is provided between the upper end of the second hanging plate and the lower end of the partition plate of the first member. When the body is inverted, the liquid enters the first measuring chamber formed between the first hanging plate and the partition plate through the liquid inflow hole, and the liquid level in the first measuring chamber closes the air pipe. When the inflow is stopped and the container body is erected from this state, the measuring liquid enters the second measuring chamber formed between the second hanging plate and the front tube portion of the second member, and the container body is inverted again. Then, the liquid in the second measuring chamber is poured out from the semicircular hole and the liquid enters the first measuring chamber.

[Problems to be solved by the invention] In the container with the liquid quantitative distributor, when the container body is returned from the inverted state to the upright state, the liquid in the first measuring chamber is a liquid passage between the lower end of the partition plate and the upper end of the second hanging plate. However, the outside air is not supplied to the first metering chamber because the liquid flowing out of the second metering chamber blocks the liquid passage. Therefore the first
The air in the container will flow into the measuring chamber, but since there is a lot of liquid in the container especially at the beginning of use and there is little air above the liquid surface, a negative pressure is created in the first measuring chamber when the container is inverted. Then, a phenomenon occurs in which the liquid flowing out from the first measuring chamber and the replacement outside air that is about to flow into the first measuring chamber alternately pass through the liquid passage, and thus the liquid flowing into the second measuring chamber is generated. It took time for the inflow.

The present invention eliminates the above-mentioned drawbacks by providing an inflow path for outside air into the first measurement chamber in addition to the liquid passage.

"Means for Solving the Problems" The container body 1 and the bottomed cylindrical body are partitioned into two left and right chambers by a partition plate 5, and one half cylindrical portion of the lower half is cut out, and one upper half portion is formed. The only side room is the first with the top closed and the bottom open
A measuring chamber 6 is provided, the other has an upper opening as a spout 7, and a lower half portion of a continuous direct passage is a second measuring chamber 8, and windows 9 and 10 are arranged side by side at a lower end portion of the first measuring chamber 6 of the partition plate 5. A first member 2 internally fitted and fixed to a mouth / neck portion 11 of the container body 1, and a bottomed semi-cylindrical shape internally fitted and attached to a lower half portion of the first measuring chamber 6, and an arc-shaped outer wall 12 A first groove is formed in a vertical groove on one side, and a first liquid passage 13 for taking in the liquid for communicating the inside of the container body 1 with the upper portion of the inside of the first measuring chamber 6 is provided on the outer surface side, and a bottom plate 14 is penetrated inside to form a container. A first air passage 15 is formed between the container body 1 and the first measuring chamber 6 that hangs down inside the body 1, and a barrier 17 is provided so as to project from the lower portion of the flat plate-shaped inner wall 16 into the room, The second liquid passage 18 that bends from the first measuring chamber 6 due to the gap between the barrier plate 17 and the bottom plate 14 and has a small passage cross-sectional area to reach the second measuring chamber 8 through the window 10 and the window 9 1 weighing room 6 The parts and the second member 3 provided with the second air passage 19 connecting the second measuring chamber 8, composed of a cap 4 which was fitted mounted to the container body opening neck 11.

"Operation" In the above, the container body 1 is inverted when the liquid is distributed. Then, the liquid in the container body 1 flows into the first measuring chamber 6 through the first liquid passage 13. In this case, the air in the first metering chamber 6 is discharged into the container body 1 through the first air passage 15, and when the liquid reaches the level "a" at the lower end when the first air passage 15 is inverted, the inflow is stopped. And weigh a fixed amount.

After that, when the container body 1 is returned to the upright state, the liquid in the first measuring chamber 6 is liquified with the board 17 at the lower end of the first measuring chamber 6 and the arc-shaped outer wall 12.
The small gap opening is bent and transferred from the second liquid passage 18 to the storage chamber 8. The liquid in the first measuring chamber is simultaneously in the second air passage.
The second liquid passage 18 does not have the small gap portion as described above, and the upper end of the passage 19 is located above the small gap mouth portion as shown in the drawing. Immediately after the liquid level in the first measuring chamber 6 drops due to the transfer from above, the upper end of the second air passage 19 is exposed above the liquid level, and thereafter the outside air passes through the second air passage 18 and the outside air enters the first measuring chamber 6. The liquid in the first measuring chamber 6 is transferred to the second measuring chamber 8 through the second liquid passage 18 by entering and replacing.

After that, the container body 1 may be inverted again and the liquid in the second measuring chamber 8 may be poured out from the spout 7 to the outside. At the time of this external pouring, since the liquid flows into the first measuring chamber 6 again, the external pouring and the primary measurement are simultaneously performed thereafter.

"Embodiment" A container with a liquid dispenser according to the present invention is a first member which forms a container body 1, a first measuring chamber 6 and a second measuring chamber 8 and is internally fitted and fixed to a neck portion 11 of the container body 1. 2.
