Title:
PRESSURE RESISTANT SELF-STANDING CONTAINER
Document Type and Number:
Japanese Patent JPH06183430
Kind Code:
A
Abstract:

PURPOSE: To provide a pressure-resistant and self-standing container which is molded integrally without use of a base cup and shows an excellent self- standing stability even when an inner pressure acts therein, by providing chamfered faces at the corners of the outside of the grounding part in respective legs.

CONSTITUTION: Five legs 10 are arranged at the same interval in the periphery at the bottom of a container 1. Respective legs 10 are extended smoothly from the shell wall of the container 1 and the container is provided with the grounding faces 11 which contact the supporting face of container at the lower end. Two chamfered faces 12 are formed at the corners of the outside of the grounding face 11 in respective legs 10. The strength of the corners provided with the chamferings 12 is increased and brings a great resistance against expansion. Accordingly, the lower end of legs 10 does not swell and it prevents the legs from uneven deformation. It is favorable to make the chamfering 12 by a plane. A concentrated force is dispersed by the plane. The strength of the part where the chamfering 12 is formed is increased.
