Reference numeral 1 is a container body, and a mouth / neck portion 3 having a male screw is erected from the upper end of the body portion 2 to the outer surface. The upper end portion of the mouth / neck portion has a smaller outer diameter than the lower portion thereof, and a groove 4 is provided around the lower end of the small outer diameter.

Reference numeral 11 denotes a liquid pouring plug, which is attached to the outer surface of the mouth / neck 3
A peripheral wall 13 hanging from the outer periphery of the top wall 12 is screwed in a watertight manner. The top wall 12 of the pouring plug has a short cylindrical portion 16 with a nozzle 15 standing upright from the inner circumference of an inward flange 14 attached to the upper end of the peripheral wall, and spirally elastic from the upper end of the short cylindrical portion to a small upper diameter. A cylinder 17 is erected, and a capped small cylinder 19 whose upper end surface is closed by a top plate 18 is erected from the upper end of the cylinder.

As shown in FIG. 2, the nozzle 15 projects from the upper part of the short tube portion 16 to the front upper side, and the screw-shaped elastic tube 17 extends from the tube wall portion on the lower end side to the upper tube wall portion. It is formed thinly along the spiral direction of. That is, in FIG. 2, the thickness is reduced in the order of a portion, b portion, c portion, and d portion. However, in contrast to the illustrated example, the thickness is the thinnest part a,
You may make it thicken sequentially with a part, a c part, and a d part. The capped small cylinder 19 and the nozzle-equipped short cylinder 16 are formed thick so as not to elastically deform.

By forming in this way, the small cylinder 19
When the top plate 18 on the upper surface is pushed down, the spiral elastic cylinder 17 is elastically deformed sequentially from the thin wall side of either the upper or lower cylinder wall to the thick wall side, and when the pushing down is released, it is elastically restored in the reverse order. .

As shown in the figure, a cap is attached to the spout plug 11.
