Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an aerosol-type ejection container.
[0002]
[Prior art]
As an aerosol-type ejection container that is generally used, an annular protrusion is provided around the upper end of the peripheral wall, and the central part of the top wall is penetrated so that the ejection stem is urged upward to stand up. An aerosol can body fitted with a push-down head with a nozzle and an inward flange attached to the upper end of the peripheral wall fitted to the outer surface of the annular protrusion are placed on the upper surface of the annular protrusion, and inside the inward flange What formed with the cyclic | annular member which raises a cap fitting cylinder from the periphery is known.
[0003]
[Problems to be solved by the invention]
Since the aerosol-type ejection container does not have a locking means that makes it impossible to depress the depression head, there is a risk that liquid may be ejected due to a child's mischief or the like.
[0004]
The aerosol-type ejection container according to claim 1 and 2 is provided with a stopper member that engages with an engagement plate protruding from the outer peripheral wall of the push-down head with nozzle and disables the push-down head with nozzle. Unless the stopper member is positioned at a position where the stopper member is not engaged with the engagement plate, the ejection is prevented from being ejected for purposes other than the original purpose due to a child's mischief or the like.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of an aerosol-type ejection container according to the present invention will be described with reference to the drawings.
A is an aerosol can. From the upper end of the peripheral wall 1, the annular protrusion 2 having a larger outer diameter than the upper end of the peripheral wall is wound up together with the outer periphery of the top wall 3, and the lower outer surface of the annular protrusion 2 and the peripheral wall are raised. (1) A groove 4 is provided around the outer surface of the upper end portion, and a stem guide tube 5 having a closed top surface is projected from the central portion of the top wall 3 and the stem guide tube top wall is penetrated so as to urge upward. In the state, the ejection stem 6 is erected.
[0008]
B is a push-down head with a nozzle, and a stem fitting tube 7 fitted to the upper end of the ejection stem 6 is suspended from the central portion of the top wall, and the outer peripheral wall 8 is suspended from the outer periphery of the top wall, and further, the rear portion of the top wall The engagement plate 9 is projected rearward.
[0009]
C is a base member, and the lower part of the inner cylinder 10a is tightly fitted to the inner peripheral surface of the annular protrusion 2, and the lower part of the outer cylinder 10b is closely fitted to the outer peripheral surface of the annular protrusion 2. The protrusion on the inner surface of the lower end is fitted into the groove 4 of the peripheral wall 1 of the aerosol can. The top surface between the inner and outer cylinders is closed with a top plate 11 and the rear portion of the top surface of the top plate is cut long in the circumferential direction to form a guide recess 12 in the circumferential direction of both front and rear openings.
The reinforcing plate 11a that connects the outer surface of the upper end of the inner cylinder 10a and the inner surface of the upper end of the outer cylinder 10b is suspended from the lower surface of the top wall 11, and the lower end of the reinforcing plate 11a is engaged with the upper surface of the annular protrusion 2. A plurality of reinforcing plates 11a are provided at predetermined intervals in the circumferential direction.
[0010]
The left and right ends of the guide recess 12 form contact step portions 13 on which a stopper member D described later can freely contact.
Further, an engaging step 14 is formed on the outer peripheral edge of the guide recess 12.
As described in claim 2, the lower end front portion of the pressing head outer peripheral wall 8 and the upper end portion of the inner cylinder 10a are connected via the elastic piece 15, thereby positioning the pressing head B with the nozzle during assembly. To make it easier.
[0011]
D is a stopper member, and the lower half of the base cylinder part 16 is fitted to the outer surface of the stem guide cylinder 5 so as not to be able to be pulled out and pivoted, and the upper end of the upright plate 17 raised from the rear part of the lower half of the base cylinder part is moved backward. Bend horizontally and bring the bent portion into contact with the lower surface of the engagement plate 9 and also hang down the left and right side plates and the front plate from the left and right side ends and the front side end of the bent portion, respectively. The lower end of the front plate is slidably engaged with the engaging step 14 while being slidably mounted on the bottom surface of the guide recess 12. On the other hand, the lower end portion of the upright plate 17 is slidably engaged with the inner surface of the rear portion of the inner cylinder 10a.
[0012]
Furthermore, the lower surface of the first engaging protrusion 18 formed on the upper outer surface of the upper half of the base cylinder portion 16 is slidably engaged with the upper surface of the second engaging protrusion 19 formed on the inner surface of the lower end of the pressing head outer peripheral wall 8. .
The lower surface of the inward flange 20 provided on the inner surface of the intermediate portion in the vertical direction of the base tube portion 16 is slidably engaged with the upper surface of the stem guide tube 5.
[0013]
Next, the operation of this embodiment will be described.
In order to eject liquid or the like in the aerosol can A, as shown in FIG. 1, the stopper member D is moved in the circumferential direction to disengage the upper end of the upright plate 17 from the engagement plate 9, and then the push-down head B with nozzle is used. May be pushed down against the upward biasing force of the ejection stem 6, and liquid or the like is ejected from the nozzle. Normally, the stopper member D is moved until it comes into contact with the contact step 13 and is detached from the engagement plate 9.
[0014]
After the ejection, as shown in FIGS. 2 and 3, the stopper member D is moved in the direction opposite to the above, and the upper end of the upright plate 17 is engaged with the lower surface of the engagement plate 9, so that Depressing can be disabled.
In the above description, the engaging plate 9 is engaged or disengaged by moving the stopper member D. However, since the ejection stem 6 is generally rotatable, the pressing head B with the nozzle is rotated. Therefore, it is possible to keep the stopper member D in a fixed state at the same time and rotate the push-down head B so that the engagement plate 9 is engaged or disengaged. . However, in this case, the elastic piece 15 is not provided, and therefore the pressing head outer peripheral wall 8 and the inner cylinder 10a are not connected to each other.
[0015]
【The invention's effect】
Since the aerosol-type ejection container according to claim 1 and 2 is provided with a stopper member that engages with an engagement plate protruding from the outer peripheral wall of the push-down head with nozzle and disables the push-down head with nozzle. Unless the stopper member is positioned at the non-engagement position, the push-down head with the nozzle cannot be pushed down. Therefore, it is possible to prevent ejection due to a child's mischief or the like.
