2. Description of the Related Art When packing, storing, or using contents in a container such as a glass bottle, when an inner plug or a hinge cap is fitted, the inner plug or a hinge cap is fitted to the mouth of the container. A fitting ridge is formed on the inner wall of the inner plug or the hinge cap to fit with the fitting ridge of the container. Inner plug or hinge cap,
The container mouth is mechanically pressed and stoppered from above, and the fitting ridge on the outer periphery of the container mouth and the fitting ridge of the inner plug or the hinge cap are firmly fitted and fitted to the container. The inner plug is provided with a spout for taking out the contents, and a means (such as a thread) for engaging the outer lid is provided on the outer peripheral surface of the cylindrical wall. When storing the contents, attach an outer lid to the inner stopper and close the lid. When removing the contents, remove only the outer lid and open the lid. Therefore, the user of the container does not remove the inner plug from the container during use. The hinge cap has an outer lid attached to the upper part of the cap body so as to be freely opened and closed by a hinge. When storing the contents, the outer lid is closed, and when removing the contents, the outer lid is opened. Therefore, even in the case of the hinge cap, the user of the container does not remove the cap body from the container when using the container.

[0003] As described above, this type of container is filled with the contents, and is quickly plugged from above with a strong mechanical force, so that the container and the inner plug or the hinge cap are firmly fitted. It is extremely difficult to remove the inner plug or hinge cap from the human power.

In recent years, caps can be easily removed from the container after the contents have been consumed, and the container can be recycled by separating and collecting the container and the cap.
And to promote the effective use of resources. For that purpose, for example, Japanese Unexamined Patent Application Publication No. 9-249246,
As described in -18260, an opening portion in which a part of the fitting ridge is not formed or extremely small is provided on the outer periphery of the container mouth portion, and the opening portion and a cylindrical wall of caps are provided. A container has been proposed in which a stick-like device such as a screwdriver or a spoon handle is inserted into a gap between the two to remove the caps according to the principle of leverage.

[0005]

The above-mentioned conventional container is
Since only the mouth is provided with an open part, if you actually insert the tip of an instrument such as a screwdriver and squeeze it, the tip of the instrument will slide on the surface of the container, and the fulcrum of the lever will not be determined, and the cap There is a problem that it is not easy to remove the kind. This is because, in order to remove the caps by squeezing with an instrument, a strong force is required to substantially deform the caps. The present invention makes use of the principle of leverage by making the tip of the device less slippery on the surface of the container and determining the fulcrum of the lever when squeezing with the device in this manner, and the caps can be easily removed. It is intended to be able to do so.

[0006]

According to the present invention, there is provided a fitting ridge for fitting an inner plug or a hinge cap around an outer periphery of a mouth, and a part of the fitting ridge is formed. In a container having an opening portion that is not formed or extremely small, a corner portion is formed on the outer peripheral side of the opening portion by notching the opening portion or the upper surface portion of the opening immediately above the opening portion. Container.

Since the corner portion is formed on the outer peripheral side of the opening by notching the opening or the upper surface of the opening immediately above the opening,
When the inner plug or the hinge cap is squeezed with the device, the corner portion acts as a fulcrum of the lever, and the inner plug or the hinge cap can be easily removed without slipping the tip of the device. The corner portion is not limited to a right angle but may be an acute angle or an obtuse angle, and may be an arc having a slightly larger radius. When the fitting ridge is formed at the uppermost part of the mouth, the upper surface of the opening is opened. When the fitting ridge is formed slightly below the uppermost part of the mouth, the opening just above the opening. A corner portion is formed by cutting out the upper surface of the portion.

When a vertical groove is formed on the outer peripheral surface of the container mouth, and the open portion is located above the vertical groove, the groove allows
The gap between the inner plug or the hinge cap and the outer peripheral surface of the container is increased, and the inner plug or the like can be more easily removed by inserting the tip of the instrument into this gap.
