The pouring barrel and the outer barrel are erected inside and outside, and a drain groove communicating with the inside of the container is formed between the barrels.

"Problems to be solved by the invention" However, in Japanese Patent Laid-Open No. 59-152160, the outer periphery of the cap that also serves as the measuring cup is detachably attached to the inner periphery of the outer cylinder which is the groove wall surface of the drain groove. Since they are screwed or engaged, there is a drawback that the screwing or engaging portion lacks watertightness and causes liquid leakage.

Further, in Japanese Utility Model Laid-Open No. 61-180961, the inner circumference of the mouth of the cap that also serves as the measuring cup is detachably screwed onto the outer circumference of the lower portion of the pouring cylinder which is the groove wall surface of the drain groove. When the stored liquid measured by the cap is poured out from the cap, the flow is obstructed by the thread on the inner circumference of the mouth of the cap, and remains in the thread, which prevents smooth flow out. .

Further, in both cases, the fluidity of the contained liquid,
Due to physical phenomena such as viscosity and surface tension, the stored liquid enters the threaded portion of the screwed cap and stops there, where it dries and deteriorates, and the contained components solidify and adhere. There is a drawback that makes screwing difficult.

The present invention seeks to eliminate these drawbacks.
