BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid pouring container capable of pouring a required amount of an internal solution, and particularly, to accurately and easily measure a required discharge amount of the internal solution. The present invention relates to a liquid pouring container provided with a measuring mechanism which can be provided in a closed lid portion of the container.

2. Description of the Related Art In a conventional container containing a liquid, in order to dispense and use the liquid in the container in a fixed amount, a measuring cup with an attached scale is used and a predetermined cup provided in the cup is used. Inject liquid up to the scale line to measure, or
The container itself has a measuring scale line, and while pouring a predetermined amount of liquid on the basis of the measuring scale line, weigh until the liquid level reaches the scale line to be used and then transfer it to a measuring cup. Was there. (Refer to Japanese Utility Model Laid-Open No. 60-195039) Therefore, a careful pouring operation is required to measure and transfer a predetermined amount of liquid to a measuring cup, and moreover, inadvertently pouring the liquid in excess of the required amount. If the liquid is dispensed too much, there is the inconvenience that the liquid must be returned to the container.

Further, as means for eliminating such inconvenience, Japanese Utility Model Publication No. 37-27678 and Japanese Utility Model Publication No. 49-14.
As described in Japanese Patent No. 6061, a measuring cylinder body having an adjusting cylinder tube inside a measuring cylinder tube provided with a measuring scale on a pipe wall is fitted into an opening of a container containing a liquid in a positionally adjustable manner, In addition, a transparent measuring tube is tightly fitted to the upper end extension of the lid screwed into the mouth of the liquid container,
It is known that a thin inner tube reaching the bottom of the container is inserted through the cap so as to be slidable in the vertical direction in the measuring cylinder tube. These are the positions of the open end of the inner tube. There is a type in which the liquid in the container is weighed by a necessary amount so that the liquid can be easily taken out by adjusting.

However, in the above example, in order to measure the required amount of the liquid in the container, the thin inner tube in the measuring tube, which is the spouting tube, is manually moved up and down to measure. It is necessary to adjust the position of the open end of the inner tube for adjustment so as to match the measuring scale of the tubular tube and set the amount of injection. Therefore, the setting work is very troublesome, and
Accurate setting of the dispensed amount requires skill, and moreover,
Since the inner tube for adjustment is only inserted and supported in the opening of the elastic stopper provided in the neck of the container, it is very unstable and it is difficult to keep the liquid spout at a fixed position. There was a problem that was.

As a solution to these problems, as disclosed in Japanese Utility Model Publication No. 57-4610, a metering plug which also serves as a lid and a pouring metering plug member is used as a mouth neck of a container. In a container that is screwed to the portion so that it can be adjusted up and down, the screwing position is moved while rotating the metering plug upward, and the pouring metering plug member is opened to suck the liquid in the container. Weighing can be done accurately and easily,
It is known that a liquid pouring hole is opened and the container is tilted so that the liquid is poured out. The measuring chamber of the container is integrally formed from a bottom wall and a peripheral wall standing upright from the peripheral edge thereof.
A suction pipe is vertically extended into the container through a passage hole formed at the center of the bottom wall, and the peripheral wall has a large-diameter cylinder part and a small-diameter cylinder part whose upper part has a large diameter and whose lower part has a small diameter. Are concentric with a step, and are fitted and fixed in the mouth and neck of the container, and the large diameter piston of the pouring metering plug member and the small diameter piston fitted with the elastic valve are fitted in the cylinder. It is configured by inserting, the suction pipe from the above structure of the measuring chamber has a small diameter in order to minimize the reflux of the content liquid sucked into the cylinder into the container, It takes time to suck up the liquid into the measuring cylinder, which is remarkable especially when a highly viscous liquid is used, and there are drawbacks such that the structure for measuring and pouring is complicated.

Therefore, the structure of the measuring chamber of the lid is simplified so that a fixed amount of the internal solution can be quickly poured out without moving or tilting the container, and excess liquid can be refluxed into the container. As shown in FIG. 3, as shown in FIG. 3, the spout cap 2 is screwed into the mouth / neck portion 1a of the container body 1 having an elastically deformable body, and a cylindrical shape is formed at the upper end of the peripheral wall of the spout cap. In a weighing and dispensing container in which the weighing container body 3 is detachably fitted, a top wall 3b is provided so as to extend from the upper end edge of the peripheral wall of the weighing container body 3, and the center of the top wall is provided. A spout 3c is provided near the lid 3 and a lid 4 is provided on the top wall 3b. The lid 4 is provided with a cylindrical blocking plug 4b standing upright to seal the spout 3c via an elastic hinge 4a. ,
Further, in the center of the bottom wall 6 of the measuring container body 3, a measuring cylinder 6b having a communication port 6a is provided upright, and the measuring cylinder 6 is provided.
The spout tube 2a standing upright in the center of the top wall of the spout cap 2 is fitted into the inside of b, and the solution suction pipe 5 is attached to the fitting tube 2b which is hung downward on the back surface of the center of the top wall. The applicant has already proposed a measurement dispensing container formed by fitting. (See Japanese Utility Model Laid-Open No. 4-7450)

In the above-mentioned measuring and dispensing container, the diameters of the dispensing cylinder 2a and the suction pipe 5 are the same as those described above.
Since it is possible to make the diameter larger than that of the suction pipe described in JP-A-4610, even when a viscous liquid is used,
When the body wall of the container body 1 is pressed and deformed inward, the internal solution is smoothly sent into the measuring chamber through the suction pipe 5, the pouring tube 2a, and the communication port 4a due to the internal pressure. And
If the pressure on the barrel wall is released when the solution is filled in the measuring chamber, the barrel wall of the container is restored, and excess solution above the lower end of the communication port is immediately returned to the container from the communication port. A fixed amount of liquid can always be measured quickly and easily. Next, the measured liquid is poured out from the pouring outlet 3c by removing the measuring container body 3 from the pouring cap 2, then opening the lid 3f to tilt the measuring container body, and it is not necessary to tilt the container. .

However, since the container has the communication port 6a communicating with the suction pipe 5 left open in the measuring chamber, if an inadvertent pressing force is applied to the container wall for some reason, the solution is There is a risk that it may be poured into the weighing chamber, and the weighing container body must be removed each time it is used, which is troublesome. Therefore, as a means for preventing such inadvertent leakage of the internal solution, as shown in FIG. 4, the cap body 3 is attached to the mouth / neck portion 1a of the container body 1 having the body portion 2 elastically deformable by pressing. In a measuring and dispensing container formed by screwing an outer cylindrical portion 3a, the inner and outer double cylindrical walls 3c and 3d forming a circular dispensing measuring chamber A having a U-shaped section are provided with the outer cylinder. The pipe fitting cylindrical portion 3e having the closed upper end surface is formed at the end of the inner cylindrical wall 3c by vertically extending from the bulging peripheral edge 3b provided on the inner peripheral surface of the fitting portion, and the liquid is provided on the upper portion of the fitting cylinder. The cap body 3 is formed by forming a pouring hole 3f, and connecting a lid 4 for closing the end portion of the cap opening via a hinge 4a to the upper end portion of the outer cylindrical portion 3a of the cap body. The liquid suction pipe 5 is fitted into the pipe fitting tubular portion 3e, and the liquid pouring hole is formed on the inner surface of the lid. The lid body 4 provided with the fitting tubular portion 4b for sealing f is detachably fitted to the upper portion of the pipe fitting tubular portion 3e so as to seal the liquid pouring hole 3f (Actual Open Sho 63-114961). No.), or at the liquid outlet opening in the vicinity of the tip of the pouring pipe formed to project in a cylindrical shape in the center of the bottom wall of the measuring chamber,
The liquid outlet plug formed on the inner surface of the outer lid penetrates the spout of the inner lid so as to be fitted and sealed (see Japanese Utility Model Laid-Open No. 3-129258), so that the liquid content leaks carelessly when the lid is closed. It is known to eliminate this.

[0009]

In the conventional liquid pouring container with a measuring chamber as described above, since the pipe diameter of the liquid suction pipe is determined by the pouring pipe of the cap body, the liquid to be used. Although a suction pipe of a size suitable for the viscosity of is used, when the content liquid becomes highly viscous, the flow of the liquid becomes poor and the liquid running out at the pouring hole becomes poor. Therefore, when the internal solution to be filled in the container is changed, the viscous resistance of the liquid in the suction pipe changes, so when different internal solutions are stored in the same type of container, it cannot be used under the optimum conditions. Therefore, every time the content liquid is changed, it is necessary to replace the entire cap body with an optimum one and use it. The present invention does not require replacement of the cap body even if the internal solution to be used is changed, and can be used under optimum conditions simply by selecting and exchanging the suction tube, and It is an object of the present invention to provide a weighing and dispensing container which has a simple structure and is not poured into a weighing chamber.

[Means for Solving the Problems] Measuring in which a cap body having a liquid measuring chamber defined by an inner lid body and an outer lid body is screwed onto the mouth and neck of a container body having a body capable of being pressed and deformed. In a pouring container, the inner lid is a cylindrical portion screwed to the outer peripheral surface of the mouth and neck of the container body, an annular flange formed on the inner peripheral surface of the upper end of the container, and the inner peripheral edge of the flange to the inside of the mouth and neck. It is formed by a bottom wall portion that hangs down on the bottom wall and a pouring tube that stands upright on the bottom wall portion. Different suction pipes are formed so that they can be exchangeably fitted and supported, and the outer lid body is fitted with a fitting cylindrical portion fitted on the outer peripheral surface of the cylindrical portion of the inner lid body, and the fitting cylindrical portion. And a top wall extending from the upper end edge of the cylindrical part extending from the upper end of the cylindrical part to form a wall of the measuring chamber, and the upper end part of the cylindrical part is provided with The lid and the closure stopper is formed on the inner surface to seal the end opening connected via a hinge constituting the cap body.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, the measuring and dispensing container of the present invention comprises a container body 1 in which a neck portion 1a is erected from a press-deformable body formed by blow molding a synthetic resin, and the mouth and neck portion. It is configured by a cap body B which defines a measuring chamber A in a joint space between the inner lid body 2 and the outer lid body 3 which are screwed together.
The inner lid body 2 has an annular flange portion 2j on an inner peripheral surface of an upper end portion of a cylindrical portion 2a formed by screwing the outer periphery of the mouth / neck portion 1a of the container body 1.
Is formed, and a spout cylinder 2b is erected in an opening 2m formed near the center of a bottom wall 2k provided in the mouth and neck from the edge of the annular flange. The bottom surface of the bulging portion is engaged with and supported by the mouth-neck edge of the container, and the outer lid body 3 has a fitting cylindrical portion 3a fitted to the cylindrical portion 2a of the inner lid 2 and a cylindrical wall portion following the fitting cylindrical portion 3a. A peripheral wall having an edge height is formed at a spout 3d provided near the center of a top wall 3c extending from an upper end edge of 3b, and a lid portion 4 is provided at an upper rear end of the cylindrical wall portion via an elastic reversing hinge 4a. In a connected structure, the engaging projection 3f provided at the connecting portion between the fitting tubular portion 3a and the cylindrical wall portion 3b engages with the engaging concave portion 2c provided on the upper surface of the annular flange portion of the inner lid. Are supported together.

[0012] Then, the pouring tube 2 which is erected on the inner lid 2
In b, the tip top wall is closed, the tip side wall is provided with a metering pouring hole 2f, the inside of the pouring cylinder is a small-diameter cylinder in the upper half, and a large-diameter cylinder in the lower half. The fitting support portion of the suction pipe in the shape of a pipe is formed in a step shape, and the tip end portion of the spout cylinder 2b is located at the center of the opening of the liquid spout 3d formed on the top wall of the outer lid 3. In addition, a cylindrical blocking plug 4b for closing the measuring and dispensing hole 2f is fitted to the tip of the dispensing cylinder 2b at the center of the inner surface of the lid portion 4 connected to the outer lid body. A sealing piece 4c is provided concentrically on the outside of the closure plug so as to engage with a locking piece 3e provided on the top wall of the outer lid.

According to the present invention having the above-mentioned structure, after the liquid detergent and other solutions are stored in the container body 1, the pouring cylinder 2
The cap body, in which the suction pipe 5 suitable for the viscosity of the content liquid is fitted and fixed in the pouring cylinder 2b in b, is screwed and fixed to the mouth / neck portion 1a of the container. Then, in use, when a fingertip is applied to the finger-hanging piece 4d of the lid portion 4 and pushed up, the lid portion pivots around the hinge 4a and opens, so that if the body portion of the container is pushed, the inside of the container is pushed. Becomes a pressurized state, and the internal solution passes through the suction pipe 5 and is poured into the measuring chamber A through the pouring hole 2f of the pouring cylinder 2b to be measured. At this time, if the outer lid body 3 is made of a transparent or semi-transparent resin and the cylindrical wall portion is graduated, the solution surface can be seen, so press the liquid surface until the position of the required graduation line is reached. By doing so, the required amount can be measured. In addition, if the solution surface is pressed until it fills the opening of the pouring hole 2f of the pouring cylinder 2b and then the pressing force is removed, the solution above the lower end surface of the opening will flow from the pouring hole 2f into the container. Since it is sucked back, a fixed amount of solution is always stored in the measuring chamber, and if the entire container is tilted, the solution is discharged from the pouring port 3d,
It is always easy to dispense a fixed amount.

After use, when the lid 4 is closed to its original position, the closing plug 4b provided on the lid fits the tip of the pouring tube 2b so as to close the pouring hole 2f and the sealing piece. 4c engages with the locking piece 3c of the inner lid, and the opening peripheral edge of the lid is held in a state of being fitted to the cylindrical wall surface of the outer lid. Therefore,
Since the measuring chamber A of the cap body is completely sealed by the closing plug 4b and the sealing piece 4c and the communication with the outside air is cut off, even if the container is impacted for some reason, the pressure inside the measuring chamber is reduced. Since it does not become a state, the solution will not overflow and accumulate in the measuring chamber, and even if the container collapses when the lid is closed temporarily while measuring and storing the solution in the measuring chamber, There is no risk of the solution leaking out.

Next, when a solution having a high viscosity is packed in the same container, the flow resistance in the suction pipe increases, and the delivery of the solution deteriorates. Therefore, the suction pipe has a large pipe diameter and flows. It is necessary to use a low resistance one. Therefore, the capping pipe 2b of the cap body of the present invention is configured so that suction pipes having different pipe diameters can be fitted as described above, and therefore, as shown in FIG. Outlet 2
It is possible to use the suction pipe 5 fitted and supported in b in exactly the same state as the above-mentioned conventional one by using a cap body in which the suction pipe 5a having a large pipe diameter suitable for the viscosity of the content liquid is replaced. It will be possible.

[0016]

As described above, the cap body of the present invention has the same structure as the suction pipe having different pipe diameters can be selected and used according to the viscosity of the internal solution to be contained. When storing different solutions in different types of containers,
Since it is not necessary to replace the cap body with a different one, and the same container can be used only by exchanging the suction pipe, it is possible to mass-produce a small number of products and keep the cost of the container low. Also, since the space defined by fitting the inner lid and the outer lid together is a measuring chamber,
It has a simple structure and is easy to mold and assemble.
Further, according to the present invention, if suction pipes having different pipe diameters are prepared as spares, it is possible to store another solution in the container main body used once and use it. And the container of the present invention,
When the lid is closed, the outlet and outlet are closed by the closure plug and the sealing piece provided on the lid, so the container may be inadvertently impacted or fallen over for some reason. Even if pressed, there is no risk of the internal solution pouring out into the measuring chamber or leaking out of the container.
