Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an industrial container for pressurized fluid in the form of an "aerosol". Furthermore, the present invention relates to a discharge device for valve operation of those containers.

To prevent accidental or inadvertent manipulation of the aerosol valve, the ejector is usually capped and the user must remove the cap to operate the ejector. However, the user holds the cap in his hand, puts it on the table,
Alternatively, there is an inconvenience that it must be placed on an appropriate table. In that case, there is a concern that the cap may be damaged or lost. Further, in a certain type of device, the discharging device is rotatably mounted on a supporting member mounted on the container so that the discharging device can be rotated by a predetermined angle. Such a device has the disadvantage that it constantly exposes the discharge nozzle to external sources of contamination, and it also requires the discharge device's mounting operation, especially alignment of the discharge device's nozzle jet with respect to the container during the filling process. If not,
There is a drawback that the operation is complicated.

It is an object of the present invention to eliminate the drawbacks of conventional drainage devices, to protect the nozzle from external contamination and to prevent valve operation until intended for use. Also,
No caps or other parts have to be removed to operate the drainage device and no special care is required when mounting the drainage device on a container with a valve.

That is, the present invention provides a lockable ejection device for an aerosol valve, which has an integral body, a base of the body has means for attaching to an aerosol container, and an upper portion of the body is a wall portion of the body. It is connected to the base in an articulated manner by a flexible tongue formed by a notch provided in the base, a discharge nozzle is provided above the side joint tongue, and the discharge nozzle is for hollow operation discharge of the valve. It communicates with the shaft tube connected to the rod. The ejection device has a ring surrounded at the top of the main body. The ring is rotatable but does not move in the axial direction, and the manual lever extends laterally. Further, the end edge of the ring on the body base side is inclined, the vertical dimension on the lever side of the ring is small, and the large side surface on the opposite side of the lever is close to the shoulder on the outer wall of the base of the body. . Therefore, when the ring is turned, the lever moves to the opposite side of the nozzle so that the articulating tongue below the nozzle can push down the upper part of the body above the base to operate the valve. The ring under the lever is short, so if the lever and nozzle are on the same side, the articulating tongue will be under the lever and the long side of the ring will abut the shoulder on the opposite base of the lever, It cannot be pushed down. Therefore, the ejection device is fixed in this position, and it is possible to prevent inadvertent actuation of the valve.

In order to protect the nozzle, it is desirable to provide a shell-like extension in the front part of the nozzle of the ring and lever in the locking position of the ejector.

Inclining the edge of the ring about 7 degrees with respect to the axis of the ring will allow the valve to operate fully.

In one embodiment of the invention, the axis of the nozzle is tilted about 120 degrees with respect to the axis of the upper body, and the nozzle normally discharges in the frustoconical wall of the upper body.

In order to avoid the need for the user to manually locate the lever, the ring and the upper portion of the main body are provided with complementary positioning means composed of elastic protrusions and notches to position the lever provided on the ring. If the lever is on the same side as the nozzle, it is in the locking position, and if it is on the side opposite to the nozzle, it is in the operating position.

The present invention further relates to an "aerosol" type pressurized container having a lockable ejection device.

The invention will be better understood from the detailed description with reference to the accompanying drawings, which show one embodiment in which there is a suggestion of choosing from numerous embodiments, applications and modifications.

In the drawings: FIG. 1 is a central longitudinal sectional view of the discharge device of the present invention in the locked position; FIG. 2 is a view similar to FIG. 1 in the operating position of the same discharge device; and FIG. 3 is the same discharge. It is a top view of an instrument.

The same members are denoted by the same reference numerals in all drawings. To simplify the drawing, the dimensions and proportions of the components are not necessarily to scale.

The illustrated ejector of the present invention comprises two members, which are molded plastic materials such as polypropylene. One member fits into the other member.
That is, the member 1 is fitted into the member 2.

The body consists of a base 3 and an upper part 4, which is articulated to an annular shoulder 5 above the base 3 via elastic tongues formed by a circumferential cut 6. Above this tongue, a discharge nozzle 7 is provided in the frustoconical wall 8 of the upper part 4. The nozzle 7 communicates with a passage 9 inclined at an angle of approximately 120 ° with respect to the axial tube 10, which is connected to a hollow actuated discharge rod 11 of the valve of the aerosol container 12. The rod 11 is shown in broken lines in FIG. The tube 10 is reinforced by radial fins 13, 13 '. A ring edge 14 and radial fins 15a to 15e are provided inside the base 4, and by fitting them into the outer periphery of the upper portion of the container 12, the main body 1 is fixed to the container (Fig. 2).

The ring 2 is rotatably attached to the upper part 4 of the main body 1, but the inner peripheral rib 16 of the ring is the cylindrical wall of the upper part 4 of the main body 1.
Since it engages with the outer peripheral groove 17 provided in 20, it does not move in the axial direction. The ring 2 has a hand lever 18 extending radially. A recess 19 for hanging the user's finger 30 on the lever 18
Are formed (FIG. 2). The edge 21 of the ring facing the shoulder 5 of the base 3 is inclined about 7 degrees with respect to the axis of the ring, the shorter edge of the ring being under the lever 18 and away from the shoulder 5. There is. Also, the longer edge of the ring is on the opposite side of the lever 18 and is close to the shoulder 5 and forms the juncture. The lever 18 has two side surfaces 22 and an upper surface 23.
In the locked position, it surrounds the nozzle 7 with the wall extending from the rib 16 (FIG. 1) and protects the nozzle from external contamination. The plate 23 has an axial protrusion 24, and the protrusion 24 is
Above the upper part 4 of the body, it engages with two notches 25, 26 provided in radially opposite positions to engage the lever and ring in the locked position (Fig. 1) or in the actuated position (Figs. 2 and 3). (Fig.).
