PROBLEM TO BE SOLVED: To protect a cover cap from slipping off easily, provide a simple constitution by the formation of a definite shape thereof and protect a pushing-down head from being pushed down unnecessarily. SOLUTION: A cover cap is provided with a flexible and deformable cap body section A with a feed opening having the interval in the peripheral direction formed smaller than the outer diameter of the peripheral wall of a pushing-down head 6 by cutting and removing a peripheral wall back section of a cylindrical body fittable on the peripheral wall outer face of the pushing-down head 6 and facing peripheral wall cut and removed faces 9, 9 each other in parallel and also engaging slidably with a front section 6a of the peripheral wall of the pushing-down head 6, a nozzle storage cylinder B protruding from the end of a front section of the cap body section A and having its lower inner face of the cylinder base section to be engaged freely with the lower outer face of a nozzle 5, a cap top wall C for blocking the upper face of the cap body section A and a fitting opening expanding notch 11 formed by cutting and removing the back side of a corner section. The lower end front section of the cap body section A is brought into contact with the upper face of a fitting cylinder 1a fitted with the upper end of a cylinder 3 when the inner face of the base section of the nozzle storage cylinder B is engaged with the outer face of the base section of the nozzle 5. |
