Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening and closing of a valve in a state in which a discharge device provided with a valve is attached to a discharge port of a container such as a pail can, a can, a plastic can, etc. The present invention relates to a tool for subdividing a liquid packed in a can or a container by performing an operation.

[0002]

2. Description of the Related Art Conventionally, tools for subdividing liquids packed in containers such as pail cans, cans, plastic cans and the like include a discharge tool attached to a discharge port of the can and a pump. The type of liquid in the can is oil,
A wide variety of chemicals, solvents, detergents, paints, etc., and the properties and viscosities of each liquid also vary. The materials and shapes of the cans are various, and the shapes of the discharge ports are also dozens. The number of cans and liquids that can use the conventional discharge tools and pumps is extremely limited. Therefore, most of the subdivision work from cans, even if a small amount is used, lift the heavy can with both hands each time, lean down and tilt the can to discharge it from the discharge port, or take out the cock. At present, a tank is prepared for subdivision with such components, and liquid is bothersomely transferred from a pail or a one-ton can, and then subdivided.

[0003]

The weight of the liquid in the can is as much as 18 kg to 25 kg, and lifting it is very hard work and many workers suffer from back pain. In addition, during the discharge work by lifting the can, the liquid scatters and stains the surroundings, adheres to clothing and skin, the can gets dirty with the liquid dripping slowly, the floor gets dirty, and cleaning is also difficult. is there. In addition, since spilled liquid cannot be used, it wastes a lot of time and supplies, and there are many liquids that are harmful to humans and the environment. Improvement is required. Accordingly, the problem is to easily take out a small amount of liquid in the can without spilling or soiling without having to carry a heavy can each time in each subdivision.

[0004] As described above, there are several shapes of the discharge port of the can. However, the present invention is directed to a can having a screw structure in which a cap for sealing the can is tightened. is there. The discharge device equipped with a valve is tightened and fixed to the discharge port of the can by turning the screw, the can is laid on its side, the valve is opened and closed, and the liquid packed in the can is taken out. Naturally, the discharge port of the can is downward, and the discharge port of the valve is also downward.
The outlet of the pail, one can, and plastic can is not integrally molded with the can body, but is attached to the can canopy, so the screw entry is not a fixed position but different for each can . Furthermore, in the case where the valve is attached and fixed to the cap of the discharge port of the can, the entrance of the screw of the lid and the direction of the valve vary, so even if such a thing is attached to the discharge port of the can and fixed, Each time, the discharge port of the valve is directed upward or sideways, or it is not known at all which direction 360 degrees will stop, so it cannot be used as a discharge tool. Therefore, the screw fastening method of the cap that seals the can is a screw, and the discharge port of the valve can be fixed with the discharge port facing downward, regardless of the size of the cap, if it is attached to any can. It is intended to provide. The present invention has been made to solve these problems.

[0005]

For the reasons described above, the discharge tool main body provided with the valve has a structure in which it can rotate freely 360 degrees separately from the tightening ring until it is fixed to the can discharge port. Then, regardless of the position of the screw, regardless of the position of the screw, when the can is laid on its side, with the discharge port of the valve facing downward, tighten the tightening ring to the discharge port of the can by turning the screw, and The body can be fixed. Lay the can on its side and place it on a dedicated shelf so that the liquid ejector attached to the can is downward, and then simply open and close the valve, and anyone can always use the required amount of liquid. It can be easily subdivided without thinking, spilling, and not getting dirty. Depending on the liquid to be used, the supply of air to prevent the inside of the can from being in a vacuum state may be performed by using an air introduction pipe provided in the discharge device main body, or by providing an air hole in the can without providing an air introduction pipe. You may open it.
