CONTAINER WITH FUNCTION FOR SUPPRESSING REFILLING

摘要

　This container with a function for suppressing refilling is configured so as to be provided, in an accommodating portion (45) which accommodates the stopper (30) of a neck portion (40), with restricting protrusions (80) which protrude to the inside of the neck portion (40) and make contact with the stopper (30), restricting movement of the stopper (30), which is held by a narrow portion (60). The container is configured such that increasing the internal pressure of a container body (20) causes the stopper (30) to expand the restricting protrusions (80) and move until engaged by engagement portions (70).
