Abstract:
The present invention addresses the problem of providing a container pouring spout sealing structure that realizes both sealability and easy opening properties, reduces the number of parts and manufacturing steps, and can also be applied even to small containers such as cosmetic containers. Provided is a sealing structure of an inside plug pouring spout that solves the foregoing problem and is characterized by: being provided with a sealing member having a bottom part for sealing an opening of the pouring spout of an inside plug, a peripheral wall rising from the peripheral edge of the bottom part, and a knob part that extends from the peripheral wall; the sealing member being connected with the upper end of the opening of the pouring spout at the peripheral edge of the bottom part; such connection portion constituting a thin part that can be broken by a constant pulling force; and the peripheral wall being formed inclined upwardly and outwardly from the opening of the pouring spout.
