<p>A hinge cap (10) fitted to a slant opening wall (26), which is provided around the opening of a hinge cap body (12), by means of two adjacently standing slant plugs (30, 32) of a lid (12). Because the slant plugs (30, 32) of the lid (12) are fitted by a large contact area to the slant opening wall (26) of the hinge cap body (12), the slant plugs can be applied to the hinge cap (10) having a relatively large area. Also, with the lid extended, the wall height of the slant outer plug (32) decreases as it approaches the rotation axis of the lid (12) and the wall height of the slant inner plug (30) decreases as it is away from the rotating shaft of the lid (12), so that the lid (12) can be smoothly rotated and opened in pressing and opening operation.</p> |
