Definitions

  • the present invention relates to an aerosol container with a cap or cover, particularly a container for facilitating safe and easy release of a pressurized gas contained in such an aerosol container for discharging the same.
  • an aerosol container is widely used for discharging various kind of agent such as a paint, a cleaner, a hair-conditioner, an aromatic, and an insecticide.
  • a container is used for not only an effective ingredient of the paint etc., but also a pressurized gas or an evaporable solvent for discharging the ingredient as a mist out of the container.
  • pressurized gas and the evaporated solvent may still remain in the container after the container is discarded as an out-of-use or unnecessary article.
  • the container with its content remaining therein should not be burned to discard, since it may be exploded.
  • the above-mentioned ingredient may be harmful to human body. Accordingly, it is desirable that the contents such as the gas are released before the container is discarded.
  • the gas or effective ingredient When the used out or unnecessary container is discarded, several methods are taken for releasing the gas or effective ingredient in the prior art.
  • One of the method is to bore a hole on a body of the container by using a nail, drill, etc., by hand.
  • the other one is to use a special boring device for making a perforation from which the gas or the ingredient is discharged.
  • the former method may cause a problem in view of safety or sanitation, since the discharged content such as the gas may fall on a person who execute the boring operation. It may also causes an another problem that contents such paint may be discharged together with the gas and soil the person or the place therearound.
  • the latter method is not suitable for a personal or a home use, since it needs a place or cost for installing the device.
  • Japanese Patent Application Laid Open 10 (1998)-53289 (which is referred to as document 1) discloses an aerosol container shown in Fig. 18(A) comprising a container body 103 with a mounting cup 104 from which a rod-shaped discharge head 102 is standing upwardly, and a cap 101 with a top wall having a fitting recess 105 which is contoured to be generally complementary to the container body's profile from the mounting cup to the rod-shaped discharge head, such that the cap is reversed to fit the periphery of the fitting recess 105 on the outer circumference of the mounting cup as shown in Fig. 18(B) such that the rod-shaped discharge head (102) is depressed by striking against the fitting recess so as to release gas outside through a gas release hole (106) formed at a portion of the fitting recess (105).
  • Japanese Utility Model Registration No. 3,056,237 (which is referred to as document 2) proposes an aerosol container shown in Fig. 19 comprising a cap with a slant top wall, a portion of the top wall is formed into a push button 110 by cutting its perimeter except for its lower side 110a such that the button is elastically bendable at the lower side so as to depress a discharge head 111 by its lower surface.
  • Japanese Patent Laid-Open No. 11 (1999)-70986 proposes a tilt-type aerosol container comprising a discharge head standing from the container body and being capable of tilting forward for discharging contents, and a cap for fitting on an upper portion of the container.
  • Said cap has a rear wall, a portion of which is cut at its upper and lower margins to form an elastic band therebetween which is adapted to turnover inwardly against its elasticity so as to tilt the discharge head forwardly due to the turnover of the elastic band.
  • Japanese Patent Laid Open No. 2001-19067 (which is referred to as document 4) proposes an aerosol container comprising a cap with a top wall, a center portion of which is formed into a convex portion protruding upward, while a depression piece is protruding downwards from the convex portion, such that the discharge head is depressed by means of the depression piece by turning over the convex portion.
  • US 3,137,414 discloses an aerosol can assembly and an activating cap for completely dispensing the container.
  • the cap comprises an actuator which actuates the lever and the valve on the spray container to put the valve in open position.
  • the actuator will continue to hold the lever in depressed position and the contents of the pressurized container will be discharged as an aerosol spray. Pressure of an individual's finger upon the lever is not required to produce a spray, tiring of a person's fingers is eliminated.
  • the container in document 1 is apt to be dirty since its fitting recess is easily soiled with dust.
  • the method according to the document 3 is only applied to the container with a tilt type discharge head.
  • the gas release may start or stop unintentionally when the elastic band contacts with something else to elastically turn over from or to an inverted position in normal use or upon gas-releasing.
  • the present applicant proposed an aerosol container with a cap, a portion of its top wall being formed into a folding plate which is capable of bending inwardly to open a gas-release aperture, such that the folding plate is fixed within the cap to maintain the depression state of the discharge head (Japanese Patent Laid Open 2000-191062 ).
  • the present invention proposes an improvement or alteration of the previous container for providing a comfortable use
  • Primary purpose of the present invention is to provide an useful aerosol container with cap allowing to perform two operations continuously with the same finger.
  • One of the operations is to open an aperture by folding a portion of the top wall or peripheral wall of the cap, and the other operation is to engage the folding plate defined by the portion with a stopper provided within the cap.
