Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ejection drive device that is set and fixed to an upper end portion of an aerosol container such as a mousse product and operates a stem to discharge the contents.

(Prior art) Since mousse product containers are easy to use, they are often used upside down.
Moreover, the tumbling valve is commonly used. The injection drive device that operates the laid-down valve tilts the injection pipe fitted to the stem to open the valve below at a constant tilt angle. However, since the sideways-over valve generally does not have omnidirectionality, it may not always be able to smoothly cope with a tilted posture, which may be inconvenient. Moreover, in order to secure the omnidirectionality, the injection structure is complicated. Further, it is not always necessary for the mousse product to be laid on its side and a straight down valve which is widely used can be used, which is advantageous in manufacturing, and the product can be diversified.

(Problems to be solved by the present invention) The present invention performs a normal valve that is opened straight down in a tilted posture of the injection pipe to ensure usability such as valve operability and to diversify aerosol products. Especially.

(Means for Solving Problems) The present invention is an injection system in which an injection pipe composed of upper and lower divided parts is spherically coupled, and a stem is pushed down by a lever to straighten down when the injection pipe is tilted. It is a drive device.

Referring to the drawings showing an embodiment, FIG. 1 is a vertical cross-sectional view of an injection driving device showing an inoperative state, and this device A is set and fixed on the valve component end side of an aerosol product container B. The device A is assembled from a fixed holder 1 and an injection pipe 2 which is divided into an upper part and a lower part and which is spherically connected.

The fixed holder 1 has a cap shape having a top wall 3, a window hole 4 is opened in the top wall 3 leaving an outer peripheral edge 3a, and a lower surface opening portion is fitted into a tightening portion 5 at an upper end portion of the container B to be inside. Stem 6
And the locking projection 7 is locked below the tightening part 5 to prevent free disengagement.

The injection pipe 2 is provided with a tilting pipe 8 in an upper part and a fixed cylinder 9 divided into a lower part, a spherical part 10 bulging to the outer periphery of the lower part while leaving an upper end 9a of the fixed cylinder 9, and a lower end of the center hole 11 is provided. It fits on the stem 6 and is fixed upright in the axial direction. The tilting pipe 8 at the upper part of the injection pipe 2 has a predetermined length, an enlarged flange 12 is integrally formed at the lower end, and a spherical recess corresponding to the spherical portion 10 from the connecting shoulder portion 14 to the lower end portion of the central hole 13. 15 are installed in a row. In the tilting tube 8, the spherical portion 10 is fitted into the spherical concave portion 15 to make spherical contact, and the upper end 9a of the fixed cylinder 9 protruding from the outer surface of the spherical body 10 is inserted into the lower end of the central hole 13 to fix the fixed cylinder 9 in place. And the outer edge 12a of the enlarged flange 12 is locked to the lower side of the outer peripheral edge 3a of the fixed holder 1.

(Operation / Effect) As shown in the longitudinal sectional view from the inoperative state of FIG. 1 to the operating state of FIG. 2, when the tilting tube 8 is tilted, a part of the engaging portion between the enlarged flange 12 and the fixed holder 1 is formed. Since the upper end 9a of the fixed cylinder 9 is inserted into the center hole 13, the connecting shoulder 14 pushes down the spherical portion 9, and the stem 6 is straightened down.

In the jet drive device of the present invention, the tilting tube 8 and the fixed tube 9 incorporated in the fixed holder 1 are connected in a spherical contact state, and the upper end 9a of the fixed tube 9 is fitted into the center hole 13 of the tilting tube 8. When the tilting pipe 8 is tilted, the fixed cylinder 9 and the stem 6 are straightened down to open the lower valve and the contents can be jetted. Since it can be applied to general-purpose ordinary valves, it is convenient for manufacturing aerosol products, and it can also be used for commercially available aerosol products for diversification. It is possible to secure a tilted posture that is easy to operate for use and to make the device easy to use.
