Abstract

PROBLEM TO BE SOLVED: To simplify the method for taking out liquid contents by a fixed quantity by a method wherein a spouting hole that discharges the liquid contents into a measuring cup by squeezing the trunk part of a container body and prevents return flow from the measuring cup to the inside of the container body when loosening the squeeze is formed at the bottom wall of the measuring cup to be inserted into the inside of the mouth part of the container body. SOLUTION: Upon using a container 1 for taking-out a fixed quantity for housing cold remedy or gargle, the container 1 is placed upside down and with the trunk part 11 thereof squeezed, liquid contents 40 in the container body 10 is discharged through a spouting hole 24 into a measuring cup 20. With the squeeze loosened, the container body 10 is restored to its original condition. As the upper end of the liquid contents in the measuring cup 20 comes to contact with the internal edge 24a of the spouting hole at the bottom wall, the liquid contents inside the measuring cup 20 returns into the container body 10 on restoration processes executed thereafter. Thereby, the liquid contents can be housed in a fixed quantity in the measuring cup 20, and the liquid contents in a fixed quantity can be taken out after the container 1 is placed upright and an outer cap 30 is removed.

[0008] The pouring hole may be formed so as to extend in the up-down direction, and may have a tapered portion whose inner diameter decreases from below to above.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a vertical cross-sectional view of the fixed quantity removal container 1 according to the present embodiment in an upright posture.

As shown in the figure, the container 1 has a flexible container body 10 having a body 11 and a mouth 12 forming an opening above the body 11, as shown in the drawing. Bottomed cylindrical measuring cup 20 inserted in a liquid-tight manner
And an outer lid 30 which is detachably attached around the mouth 12 of the container body.

The measuring cup 20 is provided at the mouth 1 of the container body.
2 a cylindrical peripheral wall 21 abutting on the inner peripheral surface in a liquid-tight manner;
A flange portion 22 extending radially outward from the upper end of
And a bottom wall 23 for closing a lower opening of the peripheral wall, and the upper part is opened. The flange portion 22 is engaged with the upper end of the mouth portion 12 of the container main body, thereby preventing the measuring cup 20 from dropping into the container main body.

The bottom wall 23 of the measuring cup has a spout hole 24 through which the contents contained in the container main body can be discharged into the measuring cup 20 by pressing the body 11 of the container main body. Are formed.

The pouring hole 24 can have various shapes. That is, as in the present embodiment, a composite type including a tapered portion 26 whose inner diameter decreases upward from the outer surface of the bottom wall and a straight portion 27 communicating the tapered portion and the inner surface of the bottom wall (FIG. 5) (see FIG. 5A), a simple straight type as shown in FIG. 5B or a taper type as shown in FIG. 5C is also possible.

The pouring hole 24 can prevent the liquid in the measuring cup 20 from flowing back into the container body when no external force is applied to the container. In particular,
The inner diameter of the pouring hole 24 may be 0.5 mm or more and 3.0 mm or less, depending on the properties and viscosity of the content liquid. 0.5mm
If the diameter is smaller than this, the dischargeability of the content liquid from the container body 10 to the measuring cup 20 may be deteriorated. On the other hand, if the distance exceeds 3.0 mm, the content liquid may return from the measuring cup 20 to the container body 10. is there.

Although the inner surface of the bottom wall of the measuring cup may be a simple horizontal surface, as in the present embodiment, a projecting portion 25 projecting inward from the bottom wall 23 of the measuring cup.
And the following effects can be obtained by forming the pouring hole 24 in the protruding portion 25.

That is, when the projection 25 is not provided, the entire measuring cup is filled with the content liquid at the time of measuring. Therefore, in the upright state shown in FIG. 4, the head space 42 is not formed between the upper opening surface 20a of the measuring cup and the upper surface of the content liquid 41 in the measuring cup, and the content liquid in the measuring cup is removed when the outer lid 30 is removed. Spills easily. On the other hand, if the projecting portion 25 is provided as in the present embodiment, when the container main body is erected after the measurement, between the upper opening surface 20a of the measuring cup and the upper surface of the content liquid in the measuring cup. A headspace 42 can be provided. Therefore, it is possible to effectively prevent the content liquid 41 from falling out of the measuring cup.

Further, by providing the projecting portion 25 and forming the spouting hole 24 in the projecting portion 25, it is possible to generate an appropriate resistance when the content liquid passes through the spouting hole. For example, when the content liquid in the measuring cup is transferred to another container after the measurement, it is possible to prevent the content liquid 40 in the container main body from being spouted even when the container body is unexpectedly pinched. In addition, when the pouring hole 24 is formed in the protruding portion 25 as in the present embodiment, the length of the pouring hole 24 is
It is preferably 8 mm or less. If it exceeds 8 mm, the resistance when the content liquid passes through the pouring hole becomes excessive, and there is a possibility that the dischargeability from the container body into the measuring cup may be deteriorated.

The outer lid 30 has a top plate 31 having an opening 12a of the container main body or an upper opening 2 of the measuring cup.
0a so as to close the opening surface located above
It is detachably attached around the container body opening 12. In the present embodiment, the flange portion 22 of the measuring cup 20 is locked to the upper end of the container main body opening 12, and the upper opening surface 20a of the measuring cup is connected to the opening opening surface 1 of the container main body.
Because it is located above 2a, when the outer lid is attached,
The top plate 31 closes the upper opening surface 20a of the measuring cup 20.

Next, a description will be given of a method of using the thus-configured fixed quantity take-out container. FIG. 2 is a vertical sectional view showing a state in which the container 1 is turned upside down, the body 11 is pressed, and a liquid content is discharged into the measuring cup 20. FIG. It is a longitudinal sectional view after being made,
FIG. 4 shows a state in which the container 1 is erected from the state shown in FIG.
It is a longitudinal cross-sectional view showing the state where it was removed.

First, when the container 1 is turned over from the upright posture to the inverted posture, and the body 11 is pinched, the pressure inside the container body 10 rises. Is the measuring cup 2 through the pouring hole 24.
It is discharged within 0 (see FIG. 2). When the pinching state is released, the container body 10 returns to its original state due to its own elasticity. In this restoration process, the air in the measuring cup 20 is drawn into the container body 10 through the pouring hole 24. That is, the liquid content in the container body 10 and the air in the measuring cup 20 are exchanged by this pinching-releasing cycle.

By repeating this pinching-releasing cycle, when the upper end of the content liquid 41 in the measuring cup 20 in the container inverted position comes into contact with the inner end 24a of the spouting hole of the measuring cup bottom wall 23, the subsequent steps are repeated. In the restoring process, as long as the inner end 24a of the pouring hole is in contact with the content liquid 41 in the measuring cup, the content liquid in the measuring cup 20 is removed from the container main body 10.
Will flow back in. In other words, measuring cup 2
Of the content liquids 41 discharged into the container body 10, the content liquid positioned higher than the inner end 24 a of the spout hole in the container inverted posture returns to the inside of the container body 10 in the process of restoring the container body. Become.

Therefore, if the user merely repeats the pinching-releasing cycle, the user can measure the volume of the content liquid defined by the inner end 24a of the pouring hole and the inner surface of the outer lid top plate 31 without looking. It can be accommodated in the cup 20 (see FIG. 3). Thereafter, as shown in FIG. 4, if the container 1 is erected and the outer lid 30 is removed, a certain amount of the content liquid can be taken out.

As described above, in the fixed amount container 1 according to the present embodiment, the user simply inverts the container and squeezes the container main body 11 without visually observing the container. The content liquid having the volume defined by the end and the inner surface of the outer lid top plate can be easily and reliably taken out.

Further, since the measuring cup 20 is inserted into the container main body 10, it is not necessary to clean the measuring cup every time it is used as in the conventional fixed-quantity dispensing container having the measuring cup as a separate body. Further, since the opening of the container body opening is liquid-tightly closed by the measuring cup 20,
There is no need to separately provide a packing member, and the cost can be reduced by reducing the number of parts.

The container body 1 is placed on the measuring cup bottom wall 23.
A spout hole 24 communicating between the inside of the container body 10 and the inside of the measuring cup 20 is formed, and the container 10 is turned upside down to squeeze the container body 11 to discharge the content liquid 40 in the container body 10 into the measuring cup 20. So that the container body 10
The content liquid in the inside can be reliably transferred into the measuring cup 20 to the end.

In the present embodiment, the outer surface of the bottom wall of the measuring cup is a simple horizontal plane. However, as shown in FIG. As shown in FIG. 6 (b), the outlet hole communicates with the inside of the concave portion 28, or the bottom wall is inclined so that the outlet hole communicates with a portion located below when the container body is in an inverted posture. Even if the liquid content in the container body becomes small, the liquid content can be reliably guided to the spout hole when the container is in the inverted position, thereby improving the dischargeability into the measuring cup. Can be done.

[0027]

According to the metering container of the present invention, there is provided a cylindrical measuring cup having a bottom without a lid for closing a container body opening forming an opening in a liquid-tight manner, and the container body opening or measuring cup opening. An outer lid adapted to be able to close an opening located above any of the above, and a bottom wall of the measuring cup,
Forming a spout hole that can discharge the content liquid into the measuring cup by pinching the body of the container body and prevent backflow of the content liquid from the measuring cup into the container body when no external force is applied Therefore, the content liquid having the volume defined by the inner end of the spouting hole and the inner surface of the outer lid top plate can be easily taken out without visual observation. In addition, since the measuring cup is mounted in the container body opening and the container body opening is covered with the outer lid, it is not necessary to wash the measuring cup every time it is used. Furthermore, since the container main body opening is liquid-tightly closed by the measuring cup, it is not necessary to separately provide a packing member.

Further, if a concave portion which opens downward is formed in the bottom wall of the measuring cup so that the pouring hole communicates with the concave portion, the content liquid in the container body may be small. Also, the content liquid can be reliably poured into the measuring cup.

Further, if the spouting hole is formed so as to extend in the up-down direction and has a tapered portion whose inner diameter decreases from below to above, discharge from the container body to the measuring cup is performed. The return of the content liquid from the measuring cup into the container body can be prevented while improving the performance.
