Description

  The present invention relates to a hinge cap.

A hinge cap having a three-point hinge mechanism composed of a hinge and an elastic band has been conventionally known, but when the cap is closed, the ridge line of the hinge is angular and both ends are corners.
In order to prevent a fingertip or other article from being caught on the corner or elastic band of the hinge, a protection piece provided outside the three-point hinge is conventionally known (see, for example, Patent Document 1). .

In the hinge cap described in Patent Document 1, the elastic band is provided on both sides of the hinge, and the protective piece is disposed outside the elastic band. Therefore, the hinge is protected together with the elastic band.

However, even with the same three-point hinge mechanism, when the hinges are on both sides of the elastic band, the outer corners of the hinge ridge line can be protected, but the inner corners cannot be covered. This method was not applicable.
In addition, the outer corner of the hinge can be easily molded so as to be rounded, but the inner corner of the hinge cannot be molded so as to be rounded.
For this reason, there is a problem that when the fingertip touches between the hinges on both sides and the finger hits the inner corner, it may cause discomfort or pain.

  In consideration of the above circumstances, the present invention provides a cap having a three-point hinge mechanism in which elastic bands are provided on the inner side and hinges are provided on both sides thereof, and a protective piece such as a rib is provided on the elastic band. It is an object of the present invention to provide a hinge cap that prevents a finger from hitting the corner of the arm and feeling pain and discomfort.

In order to solve the above-described problems, the present invention provides a hinge cap having a three-point hinge mechanism in which a resilient band is provided at the center and hinges are provided on both sides of the hinge cap at a predetermined position on the side peripheral wall of the cap body. The lower end of the elastic band is connected, and the groove around the side wall is engraved to store the elastic band when the cap is closed, and the hinge is connected to both sides of the upper end of the groove on the side wall of the cap body. The upper end of the elastic band is connected to a predetermined position on the top wall of the upper lid, and a notch having a width that allows the elastic band to slide easily is formed from the connecting section to the lower end of the side peripheral wall. A hinge is connected to both sides of the lower end of the notch on the side wall of the upper lid, and a protrusion is provided on the elastic band that extends laterally between the hinges when the cap is closed, and the height of the protrusion is hinged. The configuration is characterized in that the height is approximately equal to the height.

As another example of the hinge cap, in a hinge cap having a three-point hinge mechanism in which a resilient band is provided at the center and hinges are provided on both sides thereof , the lower end of the resilient band is connected to a predetermined position on the side peripheral wall of the cap body. The side circumferential wall circumferential surface is provided with a groove for storing the elastic band when the cap is closed, and hinges are continuously provided on both sides of the upper end of the groove on the side circumferential wall of the cap body. The upper end of the elastic band is continuously provided at the position of, and a notch having a width that allows the elastic band to slide easily is drilled from the continuous part to the lower end of the side peripheral wall. Hinges are provided on both sides of the lower end of the unit, and baffle plates are provided on both sides of the elastic band, facing the hinges when the cap is closed, on the elastic band. A configuration characterized by a height approximately equal to the height is adopted.

  As an example of the hinge, a configuration characterized in that the outer corner of the hinge is rounded is adopted.
