It becomes as the abutment 28, in a state of depressing the depressing member 30, the stopper 50, from the unlocked position away from the receiving surface 28, the left and right ends the upper surface of the stopper to the receiving surface 28 for engaging In an aerosol container that can be degassed so that it can maintain the depressed state by being advanced to the lock position ,
Each of the engagement plates 20 has a notch 24 with a lower end opening extending upward from the lower end of the engagement plate 20. The rear portion of the notch 24 extends upward shorter than the front portion of the notch 24. The left and right side portions of the stopper 50 are inserted therein, and the front upper end portion of the notch 24 provided at a low level with respect to the rear upper end portion of the notch 24 is used as the receiving surface 28. .

  In this means, a pair of engaging plates are provided on both the left and right sides of the long pressing member in the front and rear, and the pressing member is locked to the pressing position via a stopper with respect to the engaging plate so as to vent the gas. An aerosol container is proposed.

  The “aerosol container” may be either a type that ejects by vertically pushing down the stem, or a tilt type that ejects aerosol when the stem tilts backward. In the first means, “the state in which the pressing member is pressed down” includes not only the state in which the entire pressing member is pressed down but also the state in which the rear portion of the pressing member is pressed down so that the stem is tilted backward. .

The “ engagement plate” has a function of a presser portion (preferably a presser plate) that holds the pressed member in the pressed state in the pressed position against the original position restoring force via the stopper. In a preferred example described later, both the engagement plates are suspended from the top wall of the cover cylinder fitted to the upper part of the aerosol container body .

As described later, the “receiving surface” may be formed by forming a notch in a part of the engaging plate and forming the upper end surface thereof . If the stopper is installed at the rear part of the upper surface, it is easy to operate.

  The “push-down member” has a function as a push-down head with a nozzle and is formed long in the front-rear direction so that the stopper can slide between the lock position and the non-lock position of the stem. Yes.

Further, this means proposes a cover cylinder for preventing the stopper inserted between the receiving surface of the engaging plate and the pressing member from being detached due to contact with other objects. The cover cylinder is provided with a slit for operating the push-down member by inserting a finger so that the stopper can be slid to the lock position without removing the cover cylinder. Needless to say, the cover cylinder may be removed, the stopper may be set at the lock position, and the cover cylinder may be re-fitted to the upper part of the container body. Such a person can surely set the stopper in the locked position, and it is clear to the user that the degassing operation has been performed.

The second means includes a first means, and between each facing surfaces of the pressing member 30 and the stopper 50, the engagement means for retaining fit the longitudinal slidably the stopper of the stopper 48 , 54 are formed.

  For example, one of these engaging means can be formed as an engaging groove and the other as an engaging convex portion.

The third means has the first means or the second means , and is provided with a mark A relating to the degassing operation on the upper surface portion of the push-down member below the stopper, and when the stopper 50 is moved forward, the third means A sign appears.

  In this means, the both engagement plates are further arranged in a tapered shape so that the rear end side is separated from the upper side, and the push-down member is rearward from the front end side corresponding to the arrangement of both engagement plates. It is good to form so that it may become left-right wide gradually to an edge part. By adopting this configuration, a sufficient space for degassing operation can be taken.

The fourth means includes any one of the first means to the third means, and the side front portion of the push-down member 30 is pivotally attached to the engagement plate 20 and the stopper 50 is pushed down the push-down member 30. After the rear part of the push-down member 30 is pushed down via the stopper 50, the stopper 50 is slid forward as it is to be engaged with the receiving surface 28.

The invention according to the first means has the following effects.
○ After the push-down member 30 is pushed down through the stopper 50 with a finger, the push-down member can be held in a depressed state simply by sliding the stopper 50 forward. The degassing operation can be performed very easily and in a short time.
The operation of the stopper 50 can be performed with a finger from the back, and the liquid is ejected forward at that time, so that it is possible to prevent the aerosol liquid from adhering to the user's body.
○ Since the stopper 50 is slidable in the front-rear direction, it can be easily returned to its original position even if the stopper is moved forward by mistake during normal use.

Moreover , according to the invention which concerns on a 1st means, there exist the following effects.
O Since the cover cylinder 10 is provided in the upper part of the aerosol container body, it is possible to prevent other objects from touching the stopper 50 and releasing the degassing state on the way.
○ Since the cover cylinder 10 has the cut 16, the stopper can be moved to the lock position without removing the cover cylinder.

Further, according to the invention relating to the first means, since the left and right side portions of the stopper 50 are inserted into the extended portion 26 above the notch 24, the left and right width of the stopper 50 can be increased, and the gas When the stopper 50 is moved forward for the removal operation, the engagement with the engagement plate 20 can be ensured .

Further , according to the invention relating to the second means, since the engaging means 48 and 54 are formed between the opposing surfaces of the stopper 50 and the pressing member 30, the stopper 50 is prevented from unexpectedly coming out of the container body. Can be prevented.

According to the invention relating to the third means, the sign A relating to the degassing operation is provided on the upper surface of the pressing member below the stopper so that the sign appears when the stopper 50 is moved forward. For a person, it is possible to prevent forgetting the degassing operation at the time of disposal of the container, and for the garbage collector, the collection work can be performed with confidence.

According to the fourth aspect of the invention, since the aerosol container body 2 is an aerosol container body that ejects aerosol by inclining the stem 8 backward, it is pushed down via the stopper 50. After the rear portion of the member 30 is pushed down with a finger, the stopper 50 can be engaged with the receiving surface 28 by sliding the stopper 50 forward as it is. Can be operated easily.

  The aerosol container according to the present invention includes an aerosol container body 2, a cover cylinder 10, a pressing member 30, and a stopper 50. Each member excluding the container body can be formed of a synthetic resin material.

  The aerosol-type container body 2 has an engagement groove 6 provided around the upper end of the body portion 4, and the stem 8 is erected in an upward biased state from an upper end portion that protrudes from the engagement groove via a shoulder portion.
