  However, in the prior art described in Patent Documents 1 to 3, if the container body is tilted rapidly when the content liquid is poured out, the content liquid flows out from the recovery slit as well as the outflow path at the lower end of the dispensing cylinder. There is a problem that the content liquid overflows from the slit of the dispensing cylinder, and further, the content liquid jumps out from the upper end, scatters out of the container, and stains the periphery.

In addition, recently, as the contents liquid of the liquid dispensing container, refilling pouches and the like are used together with bottles for liquid detergents, softening agents, etc. Since it is commercially available and the content liquid is refilled and used many times, the usage period of the bottle is long.
For this reason, there is a problem that dirt is accumulated in the dispensing cap due to the liquid adhering each time due to liquid injection at the time of refilling, liquid overflow at the time of use, liquid recovery, and the like.

  In the liquid dispensing container described in Patent Document 4, liquid overflow from the slit of the dispensing cylinder is prevented, but due to repetition of the liquid dispensing and collection, up to contamination due to the liquid adhering to the dispensing cylinder and the dispensing cap. I couldn't prevent it.

  The liquid pouring containers described in Patent Documents 5 to 7 are designed to pour the content liquid from the pouring holes or slits provided in the inclined bottom wall of the pouring cylinder, and prevent liquid overflow and scattering. However, the liquid is not sufficiently collected, and the liquid stops and adheres to the holes and slits for liquid collection, or the liquid that adheres to the liquid reservoir accumulates dirt on the dispensing cylinder and the dispensing cap. I couldn't prevent that.

Next, the usage mode and effect of the content liquid dispensing container of the present invention will be described.
In this dispensing container, liquid clothing detergents, liquid softeners, liquid soaps and the like are used as liquid contents, and the viscosity is 1 mPa · s to 4000 mPa · s.
In the description of the table, the viscosity value has a range because the viscosity depends on the temperature, and the temperature range was 5 ° C to 30 ° C.

The assembly of the content liquid dispensing container will be described. First, the measuring portion C2 is attached to the upper portion of the cap body C1, and the measuring cap C is formed.
Next, when the measuring cap C is screwed onto the dispensing cap B and the dispensing cap B is attached to the mouth tube portion 1 of the container main body A filled with the content liquid, the content liquid dispensing container with the lid closed is obtained. Assembled.

  When using the container of the present invention, the outer circumference of the outer cylindrical wall 27 of the cap body C1 of the measuring cap C is gripped and rotated in the opening direction with respect to the dispensing cap B, and the measuring cap C is removed from the dispensing cap B. Open the lid.

As shown in FIG. 5, the measuring cap C is inverted, and the container body A is tilted so that the dispensing portion 19 of the dispensing cylinder 18 of the dispensing cap B faces downward.
By tilting the container main body A, the content liquid in the container main body A is transmitted from the spout 17 of the spout cap B through the inner periphery of the spout 19, and the liquid return cylinder 29 of the cap main body C 1 of the measuring cap C It is possible to pour into the measuring cap C from the outlet 32.

  After pouring the required amount of the content liquid into the measuring cap C, the measuring cap C is tilted to allow the measured content liquid in the measuring cap C to flow out from the outlet 32 of the liquid return cylinder portion 29 to a desired location. Can be used.

  The measuring unit C2 is made of a transparent or translucent synthetic resin, and the measuring unit C2 is graduated to visually measure the content liquid stored in the measuring cap C from outside the measuring cap C. Can do.

  Further, the measuring cap C of the present invention can determine the amount of the content liquid stored in the measuring cap C depending on the height or shape of the cylindrical wall 36 of the measuring unit C2, and therefore the measuring unit C2 of the measuring cap C. Is removed from the cap main body C1, and the amount of the content liquid that can be stored in the measuring cap C is changed by reattaching the measuring portion C2 having the separately prepared height or shape of the cylindrical wall 36 to the cap main body C1. Can do.

Below the inclined bottom wall 16 of the spout port 5 of the spout cap B of the present invention, an inclined wall 21 provided with a U-shaped cutout 23 at the end edge and a side wall 22 are formed. The size of the opening is reduced.
Therefore, when the content liquid is poured into the measuring cap C, the inclined wall 21 and the side wall 22 are formed on the spout 17 even if the content liquid in the container main body A concentrates on the spout 17 by abruptly tilting the container main body A. As a shielding wall, excessive content liquid is prevented from flowing.

Therefore, it is possible to prevent the content liquid from jumping out from the pouring part 19 and the side wall part 20 of the pouring cylinder 18 and scattering outside the container.
Moreover, since the notch part 23 is provided in the inclined wall 21, air can be introduce | transduced in a container instead of the extracted content liquid, and it has prevented that the extraction of the content liquid interrupts on the way. .

After the content liquid in the measuring cap C is poured out, the measuring cap C is tilted upright so that the liquid return cylinder portion 29 of the measuring cap C is placed in the inner cylindrical wall 6 of the pouring cap B. Attach to the dispensing cap B and close the container.
At that time, the liquid remaining in the measuring cap C is transferred from the inner periphery of the liquid return cylinder portion 29 to the inner periphery of the inner cylinder wall 6 of the pouring cap B and falls to the spout portion 5.

In the spout portion 5, the liquid that has spilled from the upper end of the pour cylinder 18 and remained on the outer periphery, and the liquid content, are moved to the lowermost portion 15 b by the inclination of the inner peripheral surface of the inclined cylinder wall 15 and the upper surface of the inclined bottom wall 16. Collected and travels along the upper surface of the inclined wall 21 and falls into the container body A from the lower end of the inclined wall 21.
Since the liquid is smoothly collected, the content liquid is less likely to adhere to the dispensing cylinder and the dispensing cap B, and the liquid contamination can be reduced.

  Moreover, when the content liquid in the container is used up, the content liquid can be easily filled into the container main body A from the spout portion 5 by pouring a new content liquid into the inner cylindrical wall 6 of the extraction cap B. .

  The spout part 5 of the spout cap B of the present invention is provided with an inclined wall 21 which is directed inward of the spout 17 and is further inclined downward from the lowermost part 15b, so that the content liquid is collected in the vicinity of the lowermost part 15b. And can be easily returned into the container body.

Next, the effect of the present invention will be described in comparison with a comparative example.
As a comparative example, the test was conducted using a dispensing cap which is currently used generally and described in Patent Documents 1 and 4.
