DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge cap suitable as a cap for a container for storing, for example, toothpaste, cosmetics, and the like.

[0002]

2. Description of the Related Art An easy-to-use hinge cap is conventionally known as a cap of a container for storing toothpaste, cosmetics, and the like. As shown in FIG. 7 and FIG. 8, the hinge cap is a cap body 2 having a mouth 1 and a lid 3 joined by hinges 4a and 4b. To use a container to which this kind of hinge cap 5 is applied,
The user flips up the tip of the lid 3 with a finger to move the hinge 4a,
The lid 3 is rotated about 4b to take out the contents from the mouth 1. Then, after use, the lid 3 may be turned again to fit the cap body 2. In this way, when a hinge cap is used as a cap for a container used on a daily basis, the opening and closing operation of the cap is smaller than that of a conventional screw-type cap or the like, which requires the lid to be completely removed from the container when opening the lid. Is extremely easy to use and there is no risk of accidentally dropping the lid.

[0003]

However, the conventional hinge cap has the following problems. For example, the hinge cap is a so-called three-point hinge having hinge portions 4a and 4b at the center and on both sides thereof, as shown in FIG. And the hinge part 4a,
4b has a certain width when viewed from the front, but is rather thin when viewed from the side. In this type of hinge cap, there is no problem in the strength of the hinge when the lid is opened from the front with respect to the hinge, but when the lid is opened from the side or when the lid is opened When a force is applied from the side, the hinge portion does not have sufficient strength, and the hinge portion may be deformed or cut by long-term use. As a measure to prevent such deformation and breakage of the hinge, it is conceivable to increase the thickness and length of the hinge.However, in this case, the rigidity of the hinge is increased, and the opening and closing of the lid becomes too hard. Failure occurs.

Further, in the conventional hinge cap, as shown in FIG. 7, both the hinge portion 4a at the center and the hinge portions 4b on both sides thereof are provided at the edge of the upper surface of the cap body 2, so that the cover portion 3 The center of rotation is also located at the edge of the upper surface of the cap body 2. When closing the lid 3,
The cylindrical portion 6 of the lid 3 is inserted into the mouth 1 of the cap body 2. Therefore, the mouth 1 opened directly above
Is inserted from an oblique direction. Therefore, when the hinge portion is deformed or cut as described above, the position of the cylindrical portion with respect to the mouth is shifted from the regular position, and there is a problem that the lid portion is difficult to close.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to prevent the hinge from being deformed or cut even if it receives a force from the side during long-term use. It is another object of the present invention to provide a hinge cap that can be easily closed.

In a hinge cap in which the lid is freely openable and closable, a concave portion is provided in the lid near the hinge, and the lid is closed and at least partially opened in the cap body. Wherein a convex portion is provided for fitting with the concave portion.

According to a second aspect of the present invention, there is provided a hinge cap, wherein a cap body having a mouth and a lid are joined by a hinge, and the lid is openable and closable with respect to the cap body. The coupling portion between the cap body and the lid portion has a hinge portion located at a position higher than the upper surface of the cap body, and the lid portion is configured to be rotatable around the hinge portion. It is.

In the hinge cap according to the first aspect, a concave portion is provided on the lid portion side, and the convex portion that fits into the concave portion of the lid portion when the lid portion is closed and at least partially opened is a cap. It is provided on the main body side. Therefore, even if an external force is applied to the lid portion from the side, the external force is reduced by the fitting portion between the concave portion of the lid portion and the convex portion of the cap body, so that no external force is applied to the hinge portion. As a result, it is possible to prevent the hinge portion from being deformed or cut even during long-term use.

In the hinge cap according to the second aspect, the joint portion of the hinge portion with the cap body and the lid portion is located at a position higher than the upper surface of the cap body, and the center of rotation of the entire lid portion is the cap body. Is higher than the upper surface of the. Here, considering that the lid is closed, as compared with a conventional hinge cap in which the center of rotation of the lid is at the same height as the upper surface of the cap body, the cylindrical portion is more open to the mouth opened upward. It will be inserted from a direction close to the vertical. As a result, compared to the conventional hinge cap,
The lid is easy to close.
