Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combination consisting of a container, an inner stopper, and an outer lid, which makes it extremely easy to open and close the mouth and neck of the container.

As is well known, in containers for various cleaning liquids such as kitchen cleaning liquid and jump liquid, an inner stopper and an outer lid are attached to the neck and neck of the container, and the inner stopper and the inner stopper attached to the neck of the container are By relatively moving the outer lid, the mouth and neck of the container can be opened and closed. Usually, the mouth and neck of the container has an outer circumferential surface with a circular cross-sectional shape, and a male thread is formed on this outer layer surface. On the other hand, the outer lid has a cylindrical skirt wall, and a male thread is formed on the inner peripheral surface of the skirt wall, which has a circular cross section. Then, by mating the male thread and the female thread, the outer lid is attached to the mouth and neck of the container. Relative movement of the outer lid of the container that opens and closes the neck of the container with respect to the neck of the container and the inner stopper attached thereto is reversed by rotating the outer lid.

That is, the outer lid is rotated in a predetermined direction, thereby raising it relative to the mouth and neck of the container and the inner stopper attached thereto;
When the container is closed, the neck of the container is opened, and when the outer lid is rotated in the opposite direction and lowered relative to the neck of the container and the inner stopper attached thereto, the neck of the container is closed. .

In recent years, there has been an increasing demand for ease of opening and closing operations at the neck and neck of the container. Not easy enough. As mentioned above, when opening and closing the neck of a container by cutting the neck of the container and the inner stopper attached to it and rotating the outer lid, it is generally necessary to hold the container with one hand and hold the container with the other hand. It is necessary to grasp the outer lid with a hand and thus rotate the outer lid relative to the container, and it is impossible or extremely difficult to open and close the neck of the container with only one hand.

The present invention has been made in view of the above facts, and its main purpose is to provide a new and excellent container that allows the user to easily open and close the mouth and neck of the container with only one hand. It is an object of the present invention to provide a combination consisting of an inner stopper and an outer lid.

According to the present invention, a combination comprising a container having a mouth and neck, an inner stopper that is attached to the mouth and neck, and an outer lid that is attached to the mouth and neck that has the inner stopper attached; The surface includes upper and lower locking protrusions located at a predetermined interval in the vertical direction at two radially opposed parts, and a lower locking protrusion located below the lower locking protrusions at a predetermined interval. The core plug has a bottom wall that closes the mouth and neck, a discharge opening is formed in the center of the bottom wall, and the outer lid has a bottom wall that closes the mouth and neck. and,
A cylindrical skirt wall that hangs down from the periphery of the top wall, a hanging column that hangs down from the center of the lower surface of the top wall, and at least two hanging pieces that hang down from the bottom end of the skirt wall at portions G that oppose each other in the radial direction. At least two radially opposing engagement protrusions are arranged at the lower part of the inner peripheral surface of the skirt wall, and a driven protrusion is arranged at the upper part of the inner surface of the hanging piece. A stop valve is formed at the lower end of the tributary column, and at least the lower part of the skirt wall and the hanging part of the outer cover are made of elastic synthetic resin. The outer lid is placed in the closed position by locking the engaging protrusion to the lower side of the lower locking protrusion of the mouth and neck, and in the closed position, the When the valve closes the discharge opening of the inner stopper and presses the depending piece radially inward, a camming action is generated by pressing the driven protrusion against the cam protrusion, causing the outer cover to move upwardly. and the engaging protrusion is moved over the lower locking protrusion of the mouth and neck to an open position located between the lower locking protrusion and the upper locking protrusion. A combination is provided, characterized in that, in the open position, the closure valve is spaced upwardly from the outlet opening of the inner plug.

According to such a combination of the present invention, the neck of the container can be opened simply by pressing the hanging piece provided on the outer lid radially inward, and the neck of the container can be opened by pressing the outer lid downward.
