Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field of a spray gun which can be reused as a liquid spray container by being attached to a used PET bottle in a general household or the like.

[0002]

2. Description of the Related Art At present, the so-called PET bottles that are discharged in large quantities from ordinary households have a recycling recovery rate of only 20 to 30%, and most of them are discarded as dust, and the municipality Currently, it is difficult to process.

[0003] Further, generally, the collected PET bottles are cut into chips and processed into fuel and other processed products, but the cost of this recycling is high and it is not profitable.

By the way, PET bottles are usually formed by blow molding polyethylene terephthalate (PET),
It is a very good liquid container with high internal pressure strength and lightness. The size and shape of the mouthpiece is common to most plastic bottles regardless of volume and shape.

Focusing on the above characteristics, liquids such as detergents and disinfectants are filled in PET bottles that have been used in ordinary households, and commercial spray guns or spray guns attached to other spray type containers are used as PET bottles. The idea of putting it on the base and using it is already recognized.

For example, as shown in FIG. 5, the existing spray gun 10 has a cap-shaped mounting portion 5 provided with an internal thread 4 and a manual pump (not shown) which is operated by the reciprocating movement of a lever 7 to form a soft plastic material. Made lip tube 6
And a spray gun body 9 configured to suck up the liquid L from the container (PET bottle 1) and spray it from the nozzle 8 at the tip, and the mounting unit 5 is attached to the male screw 3 of the base 2 of the PET bottle 1. It is used by screwing on.

[0007]

However, the conventional spray gun 10 described above has a structure including only the mounting portion 5 and the spray gun main body portion 11.
When it was attached to the mouthpiece 2, the space for grasping the lever 7 with the finger was small, and the gripping condition was not so good.

The plastic bottle 1 has various capacities from a small capacity of about 250 ml to 0.5 liter, 1 liter, 1.5 liter, 2.0 liter, and the height and shape of the container are also generally different. So Figure 5
The length of the lip tube 6 does not reach the bottom like the liquid L
It may happen that the product cannot be sucked up until the problem disappears.

Further, the base of the plastic bottle 1 has a radius of 10
Since the diameter is as small as about mm, there is a great risk of spilling when the liquid L is injected, and workability is poor. In this respect, it is easy to use a funnel, but it is not always the case that ordinary households have a funnel, and it is not feasible to use a funnel used for foods for injecting liquid detergent or the like.

The present invention provides a spray gun suitable for reusing a PET bottle as a spray container and a grip handle of the spray gun which solves the above problems.
