Description

[Detailed description of the invention] This invention relates to an improved injection lead body for pressurized containers such as aerosols. The object of the present invention is to provide a simple structure that allows the injection conversion operation to be carried out easily.

Below, the drawings showing the embodiments of the present invention will be explained.
Fig. 1 is a plan view of the injection lead body A, Fig. 2 is a vertical cross-sectional view taken along the line ■-■ with the injection lead body attached to the pressurized container B, and Fig. 3 is a half-sectional view taken along the line ■-■. Injected lead object A is an aerosol,
The annular part 1 is fitted into and fixed to the end of the valve component of the other pressurized container B, and the side part 2 is formed integrally with the annular part 1.
A crimping surface 5 that can be fitted onto the outer diameter part of the seaming part 3 on the valve component end side is provided on the circumferential inner surface of one diametrically end side, and the same seaming part 3 is provided on the other diametrical end side. The injection lead body A is provided with a bulging surface 4 that swells outward at a certain distance from the lead body A.
It is possible to fit and fix the crimping surface 5 onto the outer diameter part of the seaming part 3, and to bend and deform the bulging surface 4 into the seaming part 3 by a clamping force from the outside.

The upper surface of the annular portion 1 has an internal hole 6, leaving a flange 1b of a constant width on the outer periphery.

The internal hole 6 is a planar elliptical hole similar to the annular portion 1, and the shape of the hole can be changed by pinching and deforming the bulged surface 4.

the side part 2 is free in the internal bore 6 of said annular part 1;
The flange 1b and a part of the side part 2 are integrally connected with the elastic connecting piece 7, and the valve stem of the pressurized container B is fitted into the socket tube 8 which opens at the center of the lower surface to form an annular shape. It is elastically lifted up on the upper surface of the valve stem 1 and tamped against the elasticity of the valve stem to perform intermittent injection of the pressurized container B.

In addition, a protruding locking piece 9 is provided on the lower edge of the rear end of the side part 2 or other part of the side part 2 so as to protrude outward beyond the internal hole 6, and enters the lower side of the flange 1b to be in the locked state. Create.

From the intermittent injection of the side part 2, the side part 2 is further pushed down, and the pressurized container B forms a continuous injection by forcibly passing over the flange 1b and being lightly locked.

As described above, the internal hole 6 of the annular portion 1 is bent and deformed by pinching and pressing the bulging surface 4, so that the locking piece 9
The state of engagement between the flange and the flange 1b is canceled, and the injection is converted to intermittent injection.

The locking piece 9 may be fixed by providing a concave portion in the flange 1b and fitting the concavities and convex portions, or by providing a window hole in the rear end surface of the added portion 2 on the flange 1b side and having the locking portion 9 modified. Sometimes it is done.

2a is a finger contact surface for pressing down the extension 2, and 2b is a nozzle.

Furthermore, depending on the material of the side body, the inner hole 6 may be deformed by raising the standing portion 1a of the annular portion 1 and pressing the upper end in the diametrical direction without forming a bulging surface on the annular portion. Probably.

As described above, the present invention provides an additional part in the internal hole of the annular part which can be attached and detached to the seam part of the pressurized container, thereby making it possible to perform intermittent injection by appropriately tamping the valve stem. The locking piece of the additional portion is lightly locked to the edge of the internal hole to enable continuous injection, and the annular portion is deflected toward the center to deform the internal hole to change the locked state of the additional portion. Since the configuration eliminates the need for intermittent use of pressurized containers such as aerosols,
Continuous injection can be carried out by appropriately converting the injection, and it can be carried out extremely easily by continuing from intermittent injection by forcibly locking the annular part and releasing it by clamping and pressing the annular part. It has high practical value.
