ボトルの原材料を大幅に減少させることが出来ない問題
点の一つであった。By the way, in recent years, from the viewpoint of disposal problems at the time of disposal of bottles, raw materials of the bottles have been reduced as much as possible to reduce the weight of the bottles, and to reduce the volume and weight of the bottles at the time of disposal. ing. However, in order to reduce the amount of raw materials and reduce the volume and volume at the time of disposal, it is necessary to reduce the thickness of the parison to make the entire bottle thinner.
Manufacturing is also easy and preferable. However, when the parison is made thinner, the nozzle portion and the shoulder portion also become thinner, and the strength of the nozzle portion and the shoulder portion is remarkably reduced. The nozzle and shoulder may be deformed by the holding force of the bottle. Therefore, in order to prevent the strength of the nozzle portion and the shoulder portion from lowering, the nozzle portion has to be thickened, which is one of the problems that the raw material of the bottle cannot be significantly reduced. .

This is because, when the cap is locked by the locking portion of the nozzle portion, the gripper holding the bottle comes into contact with the flat surface of the concave portion to firmly hold the bottle, so that the rotational torque or tapping applied to the cap This prevents the bottle from rotating together with the cap due to locking force such as force. In addition, providing a horizontal bead above the concave portion reinforces the strength against the horizontal compression of the bottle when the gripper holds the bottle, and when the cap is locked to the locking portion of the nozzle portion. The strength against the axial load applied to the bottle through the cap is also reinforced. The horizontal bead may be recessed toward the center of the bottle, or may project outward.

Reinforcement is also provided, and the strength against axial load is improved as in the case of the vertical ribs 6. Further, when the periphery of the convex portion 12 is a flat portion 11, the convex portion 12 is located in the center direction of the nozzle portion as compared with a normal nozzle portion having a circular cross section and the convex portion is provided. When stopped, the cap is smoothly engaged without the inner surface of the cap coming into contact with the projection 12.
