PROBLEM TO BE SOLVED: To easily reduce the volume after a content is used up, and to reduce the transport cost, etc., by forming a spout from a half-cut groove over the whole circumference in an inner surface, etc., of the thin-walled plastic container having the spout on its top portion and a filling port in a bottom portion, and providing a handle piece having a stay on a peripheral edge inside the groove. SOLUTION: In a thin-walled plastic container 1 having a spout 10 on its top portion and a filling port on its bottom portion, the spout is formed of a half-cut groove 12 over the whole circumference of the spout 10 on the inner surface of the container 1. A handle piece 14 having a stay 16 is arranged on an inner circumferential edge of the half-cut groove 12. To unseal the container 1, the handle piece 14 is pulled, and broken off along the half-cut groove 12, and the spout 10 can be easily formed. The unsealing work is facilitated, the spout 10 is integrated with the container 1, the manufacturing efficiency is improved, the parts number is reduced, and the material cost is reduced, and in addition, the disposal, i.e., sorting collection is unnecessary, and the recycling can be facilitated. |
