Description

  The invention of the present application relates to a metering / dispensing container that makes it possible to measure and dispense the liquid content contained in a hollow container made of synthetic resin by weighing a certain amount required. More specifically, various liquid cosmetics and liquid medicines contained in a hollow container made of a synthetic resin whose body can be deformed, or various liquid detergents, syrups and the like used for bleaching clothes, washing hands, etc. Liquid liquids such as liquid reagents used in various tests, etc., are poured out from the hollow container in an appropriate amount without using a measuring cup or soiling the hands. The present invention relates to a liquid dispensing container that can be used.

If you need a certain amount of various liquid materials stored in hollow containers, prepare a measuring cup, etc. separately from the container that stores the liquid materials. The method of measuring and using a liquid substance with a measuring cup etc. was generally performed.
However, in such a method, the measuring cup is often forgotten or lost, and each time it is used, the measuring cup must be washed thoroughly before it is finished.

  Therefore, in order to eliminate the above inconvenience, as described in Japanese Utility Model Publication No. 56-5572, Japanese Utility Model Publication No. 63-35377, etc., a measurement is made on the sealing lid of the hollow container containing the liquid. Or a liquid hollow container as described in Japanese Utility Model Publication No. 54-22525, Japanese Utility Model Application Sho 60-50146, Japanese Utility Model Application Laid-Open No. 1-51043, etc. There is known a liquid dispensing container provided with a lid with a scale for weighing, in which the hermetic lid also serves as a weighing cup.

  Among these containers, the former is a scale in which the scale is printed or otherwise displayed on the wall surface of a cup-shaped container formed by injection molding or the like, so its structure is very simple and productivity is good. In general, it is widely used in terms of economy.

In the latter case, a measuring tube formed by calibrating the inner tube surface also serving as an inner plug is closely fitted to the inner surface of the mouth neck portion, and the screw of the outer tube is screwed onto the screw portion of the outer surface of the mouth neck portion. It is a container formed so as to be sealed together, and it is convenient that the lid can be removed from the mouth and neck of the container and used as it is as a measuring cup.
However, because the sealing between the inner cylinder and the mouth and neck is maintained, a slightly large force is required to remove the lid, and the two are fitted so that they can be easily removed with a small force. If the screw is loosened, the sealing degree may be lowered and the content liquid may leak, and there is room for improvement in that the shape of the lid is somewhat complicated and the productivity is inferior.

Therefore, as a dispensing container having a structure that eliminates the problems as described above, can easily weigh an appropriate fixed amount, and can be easily poured out to improve liquid drainage. The applicant has already proposed a metering container having a structure as described in Japanese Utility Model Laid-Open No. 2-97251 and Japanese Utility Model Laid-Open No. 4-21450.
As shown in FIG. 8, these quantitative dispensing containers are provided with a dispensing solution at the central part of the plug that closes the opening 21 c of the dispensing container 21 in which the body 21 b can be easily elastically deformed. The cylindrical peripheral wall portion of the inner plug body 22 having a connecting portion 22b for connecting the solution sucking pipe 24 to the lower side is provided on the outlet neck portion 22a. The liquid metering container is configured by screwing the metering tube 23 of the pouring solution with the hinge lid 25 provided with the small opening 23b to the pouring container body screwed to the portion 21a.

In order to pour out the liquid material from the metering pour container configured as described above, as shown in FIG. 8, the pour container 21 is held in the hand and the body wall 21b of the container is pressed to compress and deform. Then, the solution in the container body is pumped through the suction pipe 24 from the opening of the tip of the dispensing cylinder 22a to the measuring chamber 23a of the measuring cylinder 23. However, when the pressing force is released, the excess solution is opened at the tip of the opening. Is returned to the container body, a certain amount of solution is stored in the measuring chamber 23a.
In this way, when the dispensing container in which the solution is stored in the measuring chamber is tilted upside down after the hinge lid is opened and the body portion of the container is pressed, the content liquid is poured out from the small dispensing outlet of the hinge lid.

The above-mentioned measuring and dispensing container can measure a fixed amount of solution, and the weighed solution can be poured out from the measuring chamber little by little, and the liquid at the spout can be drained well. It is very easy to use and convenient as a metering container.
However, this can only measure a certain amount due to the structure of the measuring section, and if the body is pressed strongly during weighing or transportation, the hinge lid may open and the contents may flow out. Therefore, the applicant has proposed in Japanese Utility Model Laid-Open No. 4-13557 a dispensing container which is improved in this point so that the required amount of liquid can be measured.

  As shown in FIG. 7, the metering and dispensing container 11 improved in the above-described points has a mouth-and-neck portion 12 a that can be connected to the shoulder portion 12 b of the body portion 12 c that can be pressed and deformed to be screwed with the lid 13. A top wall 14b is provided to extend inside the standing container body 12 and the mounting cylinder portion 14a fitted to the mouth neck portion 12a so as to close the opening of the mouth neck portion 12a.

A transparent movable outer cap 15 formed so that the outer peripheral surface of the upper end of the portion 14c can be contacted in a liquid-tight manner, and the inner key. While fitted on the lower end inner peripheral surface of the-up of the pouring cylinder portion 14c, and a suction tube 16 for formed by vertically possible siphoning of the solution in the container.

  A visual line 17 for measurement is provided on the peripheral wall surface of the movable outer cap 15, and the space formed by the inner peripheral surface of the movable outer cap 15 and the outer peripheral surface of the inner cap 14 is measured. A communication port 14d that communicates from the inside of the container body to the measuring chamber 18 is formed at the upper end portion of the dispensing tube portion 14c of the inner cap so that the movable outer cap 15 is retracted to the lowered position. When the outer peripheral surface of the upper end portion of the extraction tube portion 14c is in close contact with the outlet port 15c, the measuring chamber 18 is sealed, and when the movable outer cap 15 is advanced to the raised position. The outer peripheral surface of the upper end portion of the dispensing cylinder portion 14c is separated and the dispensing outlet 15c is opened, and the measuring chamber 18 communicates with the outside.

The metering / pouring container 11 having the above-described configuration is configured such that when the movable outer cap 15 is retracted to the lowered position and the spout 15c is closed and the trunk 12c of the container body is pressed, The solution inside is poured into the measuring chamber 18 through the suction pipe 16 and from the communication port 14d of the dispensing cylinder portion 14c. By pouring together, the required amount of the internal solution can be measured.
Next, when the movable outer cap 15 is rotated and moved forward to the ascending position as shown in the drawing to open the spout 15c and then the container is turned upside down, the inner solution can be poured out from the spout. it can.

The metering and dispensing container configured as described above is very convenient because it can measure and dispense a necessary amount of the internal solution simply by pressing the barrel of the container body. Since the spout is completely closed when not in use, it can be kept clean without the risk of dust or the like entering the measuring chamber from the outside.
However, in the above-mentioned measuring and dispensing container, the structure of the container body is sucked up to the measuring chamber through the suction pipe by pressing the body part of the container body. The solution near the bottom of the container body is difficult to suck up from the suction tube, and it becomes difficult to pour out the solution in the container to the measuring chamber to the end.

Therefore, in order to solve such problems, the present invention makes it possible to measure a necessary amount of the solution in the container body without using the suction pipe as described above, The present invention provides a metering and dispensing container that can dispense as much as a drop.
And when using the above-mentioned metering and dispensing container, its usability is very good, no dripping occurs at the spout, and the closed lid of the container opens when not in use. In addition, the structure of the container is made as simple as possible to form a liquid dispensing container that can be produced at low cost.

A container for quantitatively dispensing a liquid according to the present invention is fitted to a hollow container body formed so that a body part of a container containing a liquid material can be easily pressed and deformed, and a mouth and neck part of the hollow container body. Thus, a measuring chamber for measuring the melted material poured out from the container body is formed, and the hinge chamber has a hinge lid having an opening / closing lid.

It is formed from a vertically movable hinge lid having an outer cylinder part and an inner cylinder part closely contacting and fitting to the inner peripheral surface of the inner plug-shaped member, and is measured in the space between the inner plug-shaped member and the hinge lid. In addition to forming a chamber, through holes are formed in the side wall surface of the cylindrical body of the inner plug member and the side wall surface of the inner cylinder portion of the hinge lid body so as to communicate with the vertical movement of the hinge lid body. .
The cylindrical body is formed to be compressible and deformable by the pressing force of the container body.
The lid formed in this way allows the through-hole to communicate and allows the internal solution to be introduced into the measuring chamber by turning the container body upside-down, and allows the internal solution to pass through the through-hole in a non-communication state. Configure to be pourable.

In the present invention, in order to introduce the solution in the container into the measuring chamber of the hinge lid that is screwed into the mouth and neck of the hollow container, a suction pipe is provided at the bottom of the lid as in the prior art. Rather than introducing the internal solution into the measuring chamber through a tube, a through hole is provided in the side wall of the hinge lid, and the internal solution is directly injected into the measuring chamber through the through hole with the hollow container turned upside down. Thus, the solution in the container can be poured without leaving the last.
In addition, since the suction pipe is not provided at the bottom of the measuring chamber of the hinge lid, the structure of the hinge lid is simplified, and it is easy to assemble and attach it to the mouth and neck of the container.

The container for storing the liquid contents in the present invention is molded so that the body of the container body can be easily pressed and deformed by gripping force at the same time as the body of the container is formed by blow molding of thermoplastic synthetic resin. Thus, a hollow container body is formed.
