PROBLEM TO BE SOLVED: To obtain a simple degasification method through which blowing-out of the residual liquid is minimized although it is used to blow out the residual liquid in conventional degasification works of spray cans and the residual liquid can be retained in the bottom in the inside of the spray can without spilling liquid and little possibility to stain operators and operating plsces can be left. SOLUTION: In this disposable spray can, the cap thereof is provided with a degasification structure and an upper cover 1 by which the spray can be reversely and stably erected. The upper cover is used as a receiving plate for the residual liquid and a degasification hole 2 is formed at a part of the side face. A horizontal plane part 3 is formed at the central part of the cover bottom and a trapezoidal obstacle 4 having the height to just push inward the jet button of the spray can is formed to secure the actuation space. The cap is usually put in a position where it is not obstructive and it is transferred on clegasifying a can and the spray can is reversely erected and inserted in the upper cover. |
