Claims
- 1. A cap for mounting on an aerosol container having a container body with a top end from which a discharge head is protruding upwardly, said cap comprising:a tubular body member having a lower part which is able to be engaged to an upper part of said container body, a top plate member having a periphery connected to an upper end portion of the tubular body member so as to close a top surface of the tubular body member, said top plate member having an aperture and a lid for closing the aperture, said lid having a fixed end which is connected to a margin of the aperture through a bendable line, such that the lid is able to turn from a first position in which the lid closes the aperture, to a second position in which the lid is protruding into the tubular body member so as to get in touch with a top face of the discharge head that is pressed generally downwardly, said top plate member also having a stopper for fixing the lid in the second position so as to keep the discharge head in such a pressed state, wherein aperture is located generally above the discharge head when the cap is mounted on the container; and the aperture is divided into a pair of adjacent vent holes by a generally belt-like partition plate having a pair of opposite sides; and the lid is formed by a pair of folding plates for covering said vent holes and depressing the discharge head, each said folding plate has the fixed end jointed to either of the opposite sites of the partition plate through the bendable line defined by a hinge, and is connected to a reminder of the margin of the aperture except the opposite sites through a break line, such that the pair of folding plates may turn into the second position to face each other after the break line is broken; and also that a pair of fitting portions are respectively formed on opposed faces of the folding plates for mutual engagement to join the folding plates in the second position, such that either of the folding plates functions as the stopper for immovably fix the other of the folding plates.
- 2. A cap for mounting on an aerosol container according to claim 1, wherein the first and second fitting portions are allowed to be fitted each other only when the pair of folding plates are parallel and vertical to the top plate member.
- 3. A cap for mounting on an aerosol container according to claim 2, wherein each said vent holes also functions as a finger receiving hole having a size enough to insert a finger tip of an user, such that the pair of folding plates may be pressed by the finger tips inserted through the vent holes to turn into the second position without removing the cap from the container, getting the first and second fitting portions to be engaged together; and also each said folding plate has a free end opposite from the fixed end, and a length of the folding plate between the free end and the fixed end is long enough to forcibly depress the discharge head to a discharging position but short enough to allow the free end to ride over a corner of the discharge head between the circumferential surface of the discharge head and a top surface of the same.
- 4. In a combination of an aerosol container and a cap for mounting on the aerosol container according to claim 3, wherein a chamfer is formed at the corner of the discharge head for facilitating the free end of each said folding plate to ride on the corner, when the folding plates are turned from the first position to the second position without removing the cap from the aerosol container.
- 5. A cap for mounting on an aerosol container according to claim 1, wherein the partition plate has a thickness and width sufficient for resisting a shearing stress so as to depress the discharge head by means of the folding plates, in the second position, when a user, griping the cylinder body member, removes the cap from the aerosol container to fit the first and second fitting portions, and fit the cap on the aerosol container.
