Description

The present invention relates to a cap with a clip for fixing a clip and a cap such as a writing instrument or an applicator as separate parts by fitting.

Conventionally, the writing or application tip of a writing instrument (including liquid application body, etc.) is covered with a cap body. However, when storing the writing instrument in a pocket of clothes, etc., Usually a clip is provided. And in order to raise the freedom degree of the design of a clip, a clip and a cap (cap body) are created with separate parts, respectively, and making them cap and making a cap with a clip is performed.

If the gap between the ball part of the clip (protrusion part in the shape of a semicircle in a side view protruding to the cap side of the clip) and the cap is reduced as much as possible and the writing instrument is put in a pocket or the like to point to the clip, cloth with the clip and cap Must be tightly clamped to prevent the writing instrument from falling.

In addition, when making a cap with a clip by fitting another part, even if it is set so that there is no gap at the time of designing the clip ball part and the cap, a gap is generated especially in the molded part depending on the shape of the clip and the cap. In some cases, when a gap is left, there is a problem that it is easy to come off when a clip is hooked in a pocket (usually a breast pocket). On the other hand, if the holding force by the clip ball part and the outer diameter of the cap (outer peripheral surface part) is extremely large, a strong stress is always generated on the clip and it is easy to break. There is a problem that the above-mentioned gap generation cannot be effectively prevented. Therefore, the cap with a clip that can be securely hooked when the clip is pointed to the breast pocket etc. between the clip and the side of the cap so that the entire clip tilts in the direction where the ball part touches the outer peripheral surface of the clip body Is disclosed (Patent Document 1).
