【発明の効果】本発明によれば、鉛筆型物品にキャップ
を装着するときに弾性体が変形し、内キャップ体が先端
方向に移動することで、内キャップ体内部の空気が通気

キャップが浮き上がるのを防止できる。また、キャップ
装着時は空気が逃げるために低い力で装着できる。According to the present invention, when the cap is attached to the pencil-shaped article, the elastic body is deformed, and the inner cap moves toward the distal end, so that the air inside the inner cap passes through the ventilation hole. It can be discharged to the outside through the gap between the annular end and the annular step generated by the movement of the inner cap body. Therefore, unlike the conventional case, the pressure inside the inner cap body does not increase, and it is possible to prevent the cap from floating due to the pump phenomenon peculiar to the hermetic cap. In addition, when the cap is attached, it can be attached with low force because the air escapes.

きる。Further, according to the present invention, when the mounting of the cap is completed, the inner cap body is pushed back to the opening side by the biasing force of the elastic body, and the annular end of the inner cap body and the annular step of the outer cap body are formed. The air in the cap abuts and is sealed. Therefore, after the cap is attached, the inside air is shut off from the outside air, so that volatilization and drying and solidification of the cosmetic can be prevented.

ことはない。Further, according to the present invention, when the cap is detached, the pencil-shaped article is pulled out while reducing the pressure inside the airtight inner cap body. Therefore, when the cap is detached, an extra pulling-out force is required compared to when the cap is attached, and the cap does not come off easily as in the conventional case.
