DETAILED DESCRIPTION OF THE INVENTION A wide-angle injection button for an aerosol container according to an embodiment of the present invention will be described with reference to FIGS. This wide-angle injection button is a valve that protrudes upward from the mounting cup 2 inside the shoulder cover 9 that engages with the outer peripheral recess of the curl portion 2a of the mounting cup 2 mounted on the top of the aerosol container 1. The injection button body 10 is attached to the stem 3 as well.
And the nozzle 20.

The injection button body 10 has an upper surface portion 14b which is pressed down, is connected to the inside of the peripheral surface portion 14 by a plate-shaped rib 14a, and has a valve stem 3 at the base end portion.
A tubular portion 13 having a fitting portion 11 to be formed is formed. Further, the front face portion 19 is set to be a plane orthogonal to the upward rotation center line X of the nozzle 20, and a corresponding circular concave portion on which the circular nozzle base portion 21 is rotatably seated. 19a is formed, and an annular fitting hole 17 that is concentrically engaged with the nozzle 20 so as not to come off the nozzle 20 is formed around the inside thereof. Inside the fitting hole,
The flow path 1 that communicates obliquely upward along the rotation center line X with respect to the vertical flow path 13a that communicates with the valve stem 3.
6 is formed.

The nozzle 20 includes three nozzle members 30 to 32.
The nozzle base 21 is formed on the back surface of the oval pedestal portion 22 while being formed in three columnar shapes for mounting. A concave portion 28 facing the outlet portion 16a of the flow path 16 is formed on the back surface thereof, and an annular engaging portion 29 fitted into the fitting hole 17 is provided around the concave portion 28 and the annular projection 29a is provided with irregularities. It is designed to engage.

The front of the nozzle 20 has three injection ports 39.
Is a normal position aligned in one line in the vertical direction, and is formed as three-divided nozzle front face regions 24b, 24, 24a that are tilted backward by 20 ° from the vertical plane in a side view. That is, the central nozzle front face region 24 is set to be a plane orthogonal to the rotation center line X of the nozzle 20, and the circular concave portion 2 for fitting the nozzle member 30 in the same plane.
5 and an annular engagement hole 2 into which the annular base portion 38 is inserted.
6 is formed, and the annular projection 26a engages with the projections and depressions. Similarly, the nozzle front face regions 24a, 24b
Also, a recess 25 and an engagement hole 26 for fitting the associated nozzle members 31, 32 in the same plane are formed.

As a result, the injection port members 30 to 32 have their front surfaces formed in the same plane in the central portions of the nozzle front surface regions 24a and 24b, and the injection directions of the respective injection ports 39 are
The deflection angle α is set to 20 ° on the upper side and the lower side with respect to the injection direction that coincides with the rotation center line X that is 20 ° upward from the horizontal direction of the injection port 39 in the middle, and the lower angle is set so that wide-angle injection is performed. It gradually changes from the injection port 39.
Engagement holes 26 along the ejection direction of the ejection port members 30 to 32 are partially extended as they are in a channel shape,
As shown in FIG. 2, the inlet portions 27, 2 that open into the recess 28
7a and 27b are formed and face the outlet 16a of the flow path 16 with a gap.

The operation of the wide-angle injection button configured as described above is as follows. In the state shown in FIG. 3, the three injection ports 39 are aligned in the vertical direction, and the injection port 39 on the upper side with respect to the injection angle along the rotation center line X of the middle injection port 39 with the injection direction upwards is on the upper side. 20 ° and the lower injection port 39 is deflected downward by 20 °. When the upper surface portion 14b is pushed down, the contents of the aerosol container 1 are filled with the flow path 13a,
16 and the recess 28, and the inlet portions 27, 27a, 27
Engagement hole 2 which flows into b and engages each base portion 38
It is injected from the associated injection port 39 via the annular gap on the inner peripheral side of 6. The injection direction of the lower injection port 39 is directed horizontally to the front, the injection angle of the middle injection port 39 is deflected upward by 20 °, and the upper injection angle is further deflected upward by 20 °, stepwise in the vertical direction. The wide-angle injection is changed, and the injection pattern is widened in the vertical direction by suppressing the fluctuation of the injection density distribution by combining the injections from three locations.

As shown in FIG. 4, when the nozzle 20 is grasped by hand and is rotated in the lateral direction, the inlet portions 27, 27a, 27 are formed.
In the circular concave portion 28, b rotates in a face-to-face state with respect to the corresponding circular outlet portion 16a, and at the same time, the three injection ports 39 are all aligned with the rotation center line X in a side view and are laterally oriented. Injection is performed symmetrically on both sides with an injection pattern wider than 40 °. Further, the nozzle 20 can be set at an arbitrary rotation position, and wide-angle injection can be obliquely performed at the arbitrary rotation position. At that time, the injection direction of the injection port 39 in the middle is
Since it coincides with the rotation center line X, it does not change regardless of the rotation position.

[0014]

According to the first aspect of the present invention, by the combined injection of the injection directions that change stepwise according to the tilt angle of the nozzle front area divided into a polygon from a plurality of injection ports,
Wide-angle injection is performed while suppressing variations in the density distribution of the injection amount. Due to the tilted shape of the nozzle front part, the injection direction is easy,
And it can be surely confirmed.

According to the second aspect of the present invention, the width direction of the ejection pattern can be changed from the vertical direction to the horizontal direction. Claim 3
According to the invention, the three directions of injection are combined into a wide angle, and when the wide direction of the injection pattern is set to the up and down direction, the injection is from the horizontal direction to the upward direction, and when it is set to the horizontal direction, it is symmetrical on both sides. The injection pattern spreads over the entire area, and the injection direction of the middle injection port is constant at any rotation operation position.
