Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a liquid dispensing container.
[0002]
[Prior art]
As a liquid dispensing container, a fitting tube is fitted to the outer periphery of the mouth and neck of a container body having a squeezable body, and the dispensing stopper is fixed. It is suspended from the bottom wall of the weighing chamber to be closed, and a measuring cylinder is provided in which a lower end is opened in the center of the weighing chamber bottom wall and standing in the measuring chamber, and a communication hole is formed in the upper end portion. It is known that a suction pipe is provided with an upper end connected to the lower end opening of the measuring cylinder and a lower end suspended from the lower part of the container body.
[0003]
By squeezing the barrel part of the container body, liquid is injected into the measurement chamber from the communication hole via the suction pipe and the measuring cylinder, and by releasing the squeezing of the barrel part, the liquid is poured into the measurement chamber above the communication hole. The excess liquid is allowed to flow back into the container through the communication hole, and a certain amount of liquid is measured.
[0004]
[Problems to be solved by the invention]
In this type of conventional container, as described above, excess liquid is discharged into the measuring chamber by pressing the barrel, and then the excess liquid is allowed to flow back into the container, and then the measuring liquid is poured out from the spout at the upper end of the measuring chamber. Therefore, it is necessary to make sure that liquid is introduced into the measuring chamber above the communication hole, and because the communication hole cannot be formed so large in structure, it takes some time to dispense. In addition, there are many operational restrictions such that the container must be kept upright at first, and there is room for improvement in that respect.
[0005]
In view of the above-mentioned points, the present invention proposes an excellent liquid quantitative dispensing container with few restrictions on handling and capable of quick liquid metering and dispensing.
[0006]
[Means for Solving the Problems]
As a first means, it comprises a container body 2 in which a mouth / neck part 5 is erected from a squeezable body part 4 and a fixed quantity spout 3 fitted and fixed to the mouth / neck part. A liquid introduction window hole 9 communicating with the container body at the lower part of the peripheral wall 8 is formed in a cylindrical shape of a lower end surface opening in which the outer peripheral edge is liquid-tightly fitted and fixed to the mouth and neck part, and the lower end is suspended from the container body upper part. A stopper body 6 formed by drilling a liquid extraction window hole 10 communicating with the outside at the upper part of the peripheral wall and a predetermined width on the inner surface of the peripheral wall 8 of the main body so that the outer peripheral edges are slidably fitted. The upper sliding wall 14 and the lower sliding wall 15 are integrally connected by a cylindrical connecting portion 16, and the measuring chamber A is formed by the upper and lower sliding walls 14, 15, the plug body peripheral wall 8 and the connecting portion 16. The movable member 7 is defined, and communication between the measuring chamber A and the liquid introduction window hole 9 is cut off when the movable member 7 is moved in the distal direction by squeezing the container body 4. After that, the inside of the measuring chamber A and the liquid extraction window hole 10 are configured to communicate with each other, and the top wall 11 extending from the upper end of the peripheral wall 8 and the locking protrusion 17 provided around the inner periphery of the lower end of the peripheral wall 8 are provided. Thus, the vertical movement of the movable member 7 is restricted.
[0007]
Further, as a second means, a cap 23 for covering the upper surface of the stopper body 6 by removably fitting the peripheral wall 21 around the outer periphery of the container body neck in the first means is provided. A rod-shaped protrusion 24 that hangs down from the back surface of the wall 22 through the top wall 11 of the plug body allows the lower end of the movable member 7 to be pushed down to a predetermined position.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The liquid metering container 1 of the present invention includes a container body 2 and a metering bottle 3 as shown in the drawing.
[0009]
The container body 2 is configured by raising the mouth and neck portion 5 from the squeezable body portion 4.
The quantitative dispensing plug 3 includes a plug body 6 and a movable member 7.
[0010]
The stopper body 6 is liquid-tightly fitted and fixed to the neck 5 of the outer periphery, and the lower end of the stopper body 6 hangs down to the upper part of the container body. It has a cylindrical shape with an opening at the lower end surface formed by drilling the outgoing window holes 10 respectively.
[0011]
In the present embodiment, a top wall 11 that inclines and descends toward the center from the upper end edge of the peripheral wall 8 having a smaller diameter than the mouth and neck portion 5 is extended, and the outer peripheral edge of the collar portion 12 projecting from the outer surface of the upper portion of the peripheral wall 8 is the container body neck portion 5. The stopper main body is attached and fixed to the container body by being brought into contact with the upper surface and fitting a seal cylinder 13 suspended from the outer periphery of the lower surface of the collar portion 12 to the inner surface of the mouth neck portion. In addition, a plurality of liquid introduction window holes 9 having a rectangular shape in front view are arranged in the lower end portion of the peripheral wall 8 suspended from the upper part of the container body 4 along the circumferential direction, and the upper end of the peripheral wall 8 protruding above the neck of the mouth A liquid extraction window hole 10 is formed in the front part.
[0012]
The movable member 7 has a cylindrical shape between the central portions of the upper sliding wall 14 and the lower sliding wall 15 that are slidably fitted to the inner periphery of the peripheral wall 8 of the stopper main body 6 with a predetermined vertical width. The measuring chamber A is defined by the upper and lower sliding walls 14 and 15, the stopper main body peripheral wall 8 and the connecting portion 16.
[0013]
In the present embodiment, the movable member 7 is prevented from coming off by the locking protrusion 17 provided around the inner periphery of the lower end of the peripheral wall 8. In addition, an intake valve B that unilaterally introduces outside air into the container body is provided in the connecting portion 16, so that the connecting portion 16 has upper and lower ends opened, and an upper slide having an upward skirt-like peripheral portion. The upper end is opened at the center of the moving wall 14, and the lower end is opened at the center of the lower sliding wall 15 having a downward skirt-shaped peripheral edge.
[0014]
The intake valve B is provided with a large-diameter annular recess 18 in the upper end of the inner surface of the connecting portion 16, and a valve plate 19 having an outer peripheral edge loosely fitted in the recess so as to be movable up and down. The wall portion is provided with a notch groove 20 having an open top surface and an inner side surface, and the inside of the connecting portion 16 above and below the valve plate 19 communicates with the notch groove 20.
[0015]
Then, the valve plate 19 is pushed up by squeezing the container body 4 to close the opening at the center of the upper sliding wall 14, and the upper sliding wall 14 partitions the upper and lower plug bodies 6. Further, when the squeezing of the body portion 4 is released, the valve plate 19 is configured to communicate with the inside of the connecting portion 16 via the notch groove 20 in order to release the blockage of the opening at the center of the upper sliding wall 14.
[0016]
Even if the intake valve B is not necessarily provided, the initial object of the present invention can be achieved. Further, when the intake valve B is not provided, means for preventing the upper and lower sides of the movable member 7 from communicating with each other through the connecting portion 16, for example, closing at least one of the upper and lower openings of the connecting portion 16 is applied. There is a need.
[0017]
Further, in the present invention, the movable member 7 is moved by hydraulic pressure by squeezing the container body 4, and at this time, after the communication between the measuring chamber A and the liquid introduction window hole 9 is blocked, the measuring chamber A The dimensions are adjusted so that the inside and the liquid extraction window hole 10 communicate with each other. Therefore, if the body part 4 is squeezed after the container is tilted or inverted, the liquid in the container first flows into the measuring chamber A through the liquid introduction window hole 9, and then the movable member 7 moves in the distal direction. When the communication between the measuring chamber A and the liquid introduction window hole 9 is interrupted, a certain amount of liquid is measured into the measuring chamber A. Further, when the movable member 7 moves, the inside of the measuring chamber A and the liquid injection are transferred. The outlet window hole 10 communicates with each other so that a fixed amount of liquid is discharged from the liquid outlet window hole 10 to the outside.
[0018]
In the present embodiment, a peripheral wall 21 is detachably fitted to the outer periphery of the container body neck 5, and a cap 23 that covers the top surface of the plug body 6 with a top wall 22 extending from the upper end edge of the peripheral wall 21 is provided. A rod-like protrusion 24 that is suspended from the back surface of the top wall 22 of the cap 23 is configured to be capable of being pushed down to a predetermined position at the lower end of the movable member 7. The rod-shaped protrusion 24 is suspended through the insertion hole 25 formed in the center of the top wall 11 of the plug body 6 so that the lower end is in contact with the upper surface of the movable member 7 at the lowest position. Thus, the opening at the center of the upper sliding wall 14 can be closed. Further, a seal cylinder 26 is suspended from the back surface of the top wall 22 and is configured to be liquid-tightly fitted to the inner surface of the seal cylinder 27 erected on the upper surface of the flange 12 of the plug body 6.
[0019]
In the case of using the container configured as described above, for example, when the cap 23 is removed from the state shown in FIG. The valve plate 19 closes the opening at the center of the upper sliding wall 14 (FIG. 2A). Next, the movable member 7 moves toward the distal end of the plug body 6, and the lower sliding wall 15 moves upward from the upper edge of the liquid introduction window hole 9 (because of the inverted state, precisely below the lower edge). When communication between A and the liquid introduction window hole 9 is blocked, a certain amount of liquid is measured in the measuring chamber A. Next, when the movable member 7 still moves, the upper sliding wall 14 moves upward from the lower end edge of the liquid pouring window hole 10 (because it is in an inverted state, precisely below the upper end edge), and into the measuring chamber A. Since the liquid extraction window hole 10 communicates, a certain amount of liquid is extracted from there (FIG. 2B).
[0020]
Next, when the squeezing of the body part 4 is released, the container body becomes negative pressure due to the elastic restoring force of the body part 4, and accordingly, the movable member moves toward the proximal end of the plug body.
[0021]
Next, by attaching the cap 23, even when the movable member 7 is not lowered to the lowest end, it can be pushed down by the rod-like protrusion 24.
[0022]
Each of the above members is mainly formed of a synthetic resin, and a flexible elastomer or the like can be used together as necessary.
[0023]
