This aerosol container with an injection needle is provided with a cap 2 on the upper part of a container body 1 that can be grasped by one hand, and has an elongated cylindrical shape as a whole.

The container main body 1 is provided with a storage chamber inside a main body (not shown), in which liquid such as insecticide is stored together with a propellant, and the upper end is covered with a lid 5 as shown in the drawing. U The lid portion 5 is provided with a winding fastening portion 5a on the outer periphery thereof, an outlet of the storage chamber is provided in the central portion, and an ejection valve (not shown) is provided therein. A vertically movable jet pipe 6 is connected to the jet valve. The jet pipe 6 has an upper portion projecting upward from the lid portion 5 of the container body 1 and is provided so that the jet valve, which is normally closed, can be opened during downward movement.

The cap 2 is attached to the top of the container body 1. The cap 2 is made of a plastic material, and the inner tubular portion 2b is double provided inside the outer tubular portion 2a, and the engaging convex portion 2c is provided on the inner periphery of the lower end portion of the inner tubular portion 2a. Then, the inner cylindrical portion 2b is firmly fitted to the winding tightening portion 5a of the lid portion 5 from the outside so as not to rotate, and the engaging convex portion 2c is engaged under the winding tightening portion 5a for removal. It is impossible to install. A notch 2d is provided on the outer circumference of the upper portion of the cap 2 by notching the outer cylinder 2a and the inner cylinder 2b in the radial direction. Further, a lateral hole 2e is provided by penetrating the outer tubular portion 2a and the inner tubular portion 2b in the radial direction. The notch 2d and the lateral hole 2e are arranged in the diameter direction of the cap 2 and communicate with the central hole 2f of the inner cylindrical portion 2b. A window hole 2g is provided below the inner cylindrical portion 2b on the side where the lateral hole 2e is located.

The connecting member 10 is firmly fitted and provided in the lateral hole 2g of the cap 2. The connecting member 10 has a threaded portion 10a protruding in the center of the front surface and an internal passage 10b penetrating from the front end of the threaded portion 10a to the rear surface. A screw member 9 at the base end of the injection needle 8 is screwed onto the threaded portion 10a of the connection member 10 to connect the injection needle 8 and the connection member 10.

On the other hand, one end of the transparent tube 14 is connected to the rear end of the internal passage 10b of the connecting member 10. The transparent tube 14 is a member that forms a jetting path between the jetting tube 6 of the container body 1 and the jetting needle 8, and is provided by being bent in the central hole 2f, and the other end is connected to the button member 15. To do. The button member 15 is tubular and has a flange 15a on the outer periphery of the lower end and an internal passage 15b, and the internal passage 15b and the ejection pipe 6 are connected to each other. The connecting member 10, the transparent tube 14, and the button member 15 are a unitized set product as shown in FIG.

An operating lever 16 for the button member 15 is provided in the lower portion of the cap 2. As shown in FIG. 5, the operating lever 16 is integrally formed with a rear finger hook portion 16a and a front bifurcated piece portion 16b, and locking projections 16c are formed on both sides of the tip portion of the bifurcated piece portion 16b. To provide. Then, the button member 15 is inserted from the side of the cutout portion 2d and clamped by the forked piece portion 16b to engage with the flange portion 15b as shown in FIG. The locking projection 16c is hooked on the edge of the window hole 2g.

Further, as shown in the figure, the cap 2 is provided with a transparent cover 18 also shown in FIG. The transparent cover 18 includes a substantially half-moon shaped upper surface portion 18a, a bent portion 18b perpendicular to the upper surface portion 18a, and an elastic piece 18c protruding below the upper surface portion 18a. Then, the upper surface portion 18a is fitted to the upper end of the center hole 2f of the inner cylindrical portion 2b, the elastic piece 18c is appropriately hooked, the transparent cover 18 is attached to the cap 2, and the transparent cover 18 is used to form a transparent tube. 14 wearing.

When using the aerosol container with the injection needle, the container body 1 is grasped with one hand and laid sideways, and the injection needle 8 is pierced into the tatami surface. In that state, when a finger is put on the finger-holding portion 16a and the operation lever 16 is pushed down, the button member 15 is lowered, and the ejection pipe 6 is pushed down via the button member 15. Then, an ejection valve (not shown) is opened, the liquid in the container body 1 is guided to the ejection passage in the transparent tube 14 through the ejection pipe 6, and ejected from the ejection needle 8 into the tatami mat. At that time, the liquid flowing through the ejection passage in the transparent tube 14 through the transparent cover 18 can be seen from the outside of the cap 2, and the flow state can be visually observed.

In the embodiment described above, the member forming the ejection passage is formed of the transparent tube 14, and the transparent tube 14 is covered with the transparent cover 18 attached to the cap 2. However, although not shown, the member forming the ejection path may be formed of a transparent material other than the transparent tube 14, or the transparent cover 18 may be omitted.

[0019]

Therefore, according to the present invention, when ejecting from the ejection needle by pushing down the ejection pipe, the liquid flowing in the ejection passage can be seen from the outside of the cap, so that the ejection state can be confirmed.

According to the second aspect of the invention, at this time, the transparent tube can be protected from the outside by the transparent cover to prevent the damage.
