Widely provided. Therefore, even if the water drop 29 adheres to the shoulder portion 27, the capillary action does not occur around the air hole 17, and even if the water drop 29 attaches to the upper portion of the flange 33 and the capillary action occurs, the air hole 17 is generated. Since it is not near, the water drop 29 is rarely drawn to the air hole 17. Therefore, the water droplets 29 do not enter the space between the outer layer 9 and the inner layer 11 from the air holes 17.

側層９と内側層１１の間の空間に侵入することはない。In this modification, when the spout cap 21 (not shown) is attached to the mouth tube portion 5, a large notch 35a is formed below the air hole 17 between the bottom portion 23 and the shoulder portion 27 of the spout cap. Since it is provided, the capillarity does not occur, and the water droplet 29 attached to the shoulder portion 27 is not attracted to the vicinity of the air hole 17. In addition, a small cutout 35 is formed between the bottom portion 23 and the shoulder portion 27 of the pouring cap on the uneven surface.
Since b is provided, the capillarity does not occur and the water droplets 29 attached to the shoulder 27 are not attracted to the vicinity of the air hole 17. Further, since the area of the upper surface of the flange 33 is smaller than that of the annular flange, even if the water droplet 29 adheres to the flange 33, the amount of the water droplet 29 rising due to the capillary phenomenon can be suppressed. Therefore, it is possible to minimize the water droplets 29 that flow into the air holes 17 when the bottle body 1 rolls over. Therefore, the water droplets 29 do not enter the space between the outer layer 9 and the inner layer 11 from the air holes 17.
