[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual pump type liquid ejecting apparatus for ejecting an aqueous solution or an emulsion in a water column or mist.

[0002]

2. Description of the Related Art A large number of injection apparatuses of this kind have been proposed in the past and are very well known. Japanese Utility Model Application No. 2-81653 is an example of an apparatus for injecting a water-soluble liquid into a water column.

As can be seen from this example, this type of injection device has a manually operated pump-type injector main body attached to the mouth of a container with a screw cap.

That is, a press-down head with a nozzle tube is connected and fixed to the upper end of a stem rising upward and outward from a vertical cylinder provided in the mouth of a container body, and the press-down head is pressed down against a return spring. In this manner, the liquid in the cylinder is pressurized by the cylindrical piston at the lower end of the stem, and the pressurized liquid is discharged from the nozzle pipe to the outside by opening the discharge valve of the stem by itself.

[0005] When the liquid injection is completed, the movable parts of the cylindrical piston, the stem, and the push-down head are returned upward by a return spring. The suction valve is opened to draw liquid from the container into the cylinder and prepare for the next injection.

[0006]

Problems to be Solved by the Invention In recent years, containers of this kind, especially those for rinsing and shampooing, have become large in size and are difficult to grasp with one hand.

On the other hand, since a liquid is ejected when this kind of container is inadvertently pushed down, a lock mechanism for locking the push down is adopted. For this reason, some means have conventionally been provided. As is well known as a typical one, the press-down head is pressed down to the lower limit position, and the press-down head is screwed to the screw member of the screw cap at this position. Each of them has a single function of the lock.

An object of the present invention is to provide a liquid ejecting apparatus equipped with an auxiliary member having both a handle for carrying and a lock piece for locking the pushing down of the pushing down head.

An embodiment will be described below with reference to the drawings.

The injector body 2 including the container 1 and the screw cap 3 is not only a well-known matter, but is not directly related to the gist of the present invention, and is described in the section of the prior art. Let me explain it very briefly.

The injector body 2 has a suction pipe communicating with a vertical opening through a bottom opening of the vertical cylinder, a suction section provided with a suction valve at the bottom opening, and a stem 10 having a discharge valve rising upward from the cylinder to the outside. A push head 9 with a nozzle tube 11 at the upper end of the stem 10 and a movable part with a cylindrical piston fixedly connected to the lower end of the stem 10 in the cylinder. It is configured to be pushed up to the position, and the fixing part is the container 1
It is attached to the mouth of the container body 1 by a screw cap 3 as shown in FIG.

Therefore, when the movable part is pushed down through the push-down head 9 at the top against the return spring, the liquid stored in the cylinder is pressurized, passes through the stem 10, and is discharged from the nozzle tube 11 of the push-down head 9 to the outside. Can be injected at
The movable portion is pushed upward by a return spring, and at this time, the inside of the cylinder is made negative pressure, so that the container 1
The liquid is sucked up from.

Incidentally, there is usually a mounting gap a between the screw cap 3 and the upper end of the shoulder of the container body 1 as shown in FIG.

The auxiliary member 8 is made of a synthetic resin material. The auxiliary member 8 is a part having a shape in which a push-down lock piece 6 is erected from the upper end of the holder 4 and a handle 7 is projected outward and outward.
Although the upper end portion of the embrace 4 is substantially semi-cylindrical, it gradually increases in size toward the lower portion and exceeds the half-cylindrical shape. In addition, an inward flange 12 is formed at the upper end, and engaging projections 13, 13 are formed on both sides near the tip of the inner surface at the lower end, and are formed to have a strong elasticity by making the thickness appropriate. I have.

The push-down lock piece 6 is connected to the push-down head 9.
Those of the semi-cylindrical lower surface diameter of, are erected upwardly through the broken piece 5 from the inner edge of the inward flange 12, also handle 7,抱着body in the form of a longitudinal troublesome L-shaped 4. Projected outward from the outer surface of the upper end.

The broken piece 5 may be one obtained by cutting a thin line into a broken line, or may be a discrete piece of several breakable connecting pieces. In addition, although the inverted L-shaped handle is shown as the handle 7, the shape of the handle 7 may be arbitrarily determined.
Needless to say, it can be made into a shape that does not protrude outward so as not to be bulky in a package or packed in a box.

As shown in FIG. 1, the auxiliary member 8 forcibly pushes the holding member 4 into the outer surface of the screw cap 3 from the side to elastically hold the holding member 4. At this time, the holding member 4 The engaging projections 13 at the lower end are engaged with the gap a, which is the lower end surface of the screw cap 3, and the inward flange 12 at the upper end is hung on the upper surface of the screw cap 3 to strongly embrace the outer surface of the screw cap 3. At the same time, the upper and lower surfaces are clamped and fixedly attached, and the push-down lock piece 6 is inserted between the upper surface of the screw cap 3 and the lower surface of the push-down head 9 along the outer surface of the stem 10.

Therefore, according to this embodiment, even a large container can be easily carried by the handle 7, and the push-down lock piece 6 can prevent an inadvertent push-down during distribution. In addition, when used, it is sufficient to break the broken pieces 5 and remove the lock pieces 6, and there is no trouble.

The liquid ejecting apparatus according to the present invention does not require any processing on the main body side, and therefore has an advantage that it can be applied to existing products.

It is needless to say that the liquid ejecting apparatus of the present invention is not limited to the method described in the above embodiment.

Further, if the holding member 4 is partially welded to the screw cap 3 by ultrasonic means after the auxiliary member 8 is attached, for example, the virgin seal function can be given to the push-down lock piece 6. Become.
