DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for filling a hollow container with a liquid such as paint or thinner without scattering or dripping to the outside.

[0002]

2. Description of the Related Art As a method for filling a hollow container such as an oil can with a liquid such as paint or thinner, for example, a tip of a cylindrical nozzle communicating with a liquid storage unit is inserted into an opening of a canopy of the container. For this purpose, these liquids are pumped and filled into containers. However, this method has various drawbacks such that the liquid pumped into the container hits the bottom wall or the like and rebounds and scatters outside, or the liquid easily flows out of the opening and sags.

SUMMARY OF THE INVENTION The present invention has an object to solve the above-mentioned defect in filling a liquid into a container.
As a result of intensive research, by using specific nozzles,
The present inventors have found that the object can be achieved, and completed the present invention.

That is, according to the present invention, a nozzle having a plurality of through-holes and a part of the through-holes being inclined when filling the inside of the hollow container with the liquid from the opening of the canopy. The present invention relates to a method for filling a hollow container with a liquid, characterized by filling the inside of the container with a liquid via a liquid.

The method for filling a hollow container with a liquid according to the present invention will be specifically described below.

[0006] The container to which the method of the present invention can be applied is not particularly limited. Specifically, a rectangular or cylindrical metal or plastic container having a capacity of about 18 to 20 liters, preferably 18 liters, is used. Particularly suitable. These containers are sealed by a canopy, and a part of the container is provided with an opening for taking in and out of a liquid. The opening is preferably circular and has a diameter of about 40-60 mm, especially 4 mm.
0-50 mm is suitable.

In the present invention, the liquid is filled into the container through the opening through a “specific nozzle”. The specific nozzle has a plurality of through holes, and a part of the through holes is formed. It is necessary to use one in which the direction of the hole is inclined.

[0008] The shape of the nozzle is preferably disk-shaped, and its diameter is preferably the same as or close to the opening of the container canopy. And the surface has a plurality of through holes. The through-hole penetrates from the front surface to the back surface of the nozzle and has a diameter of about 1.5 to 3 mm, particularly 2 to 3.
2.5 mm is suitable. This through-hole has a plurality of concentric nozzles of a disk-shaped nozzle, and has 2 to 10 rows, particularly 3 to
Five rows are suitable. As a specific example, one from the center,
Although there are six, twelve, and eighteen through holes provided concentrically, the present invention is not limited to this.

In the present invention, it is necessary to incline a part of the through hole. Place the disk-shaped nozzle horizontally, perpendicular to it (vertical direction) (vertical hole),
10 to 30 degrees with respect to this perpendicular direction, preferably 13 to 30 degrees
Two types of through holes coexist in a direction inclined at 18 degrees (inclined holes). The ratio and position of the two types of through-holes are not particularly limited, but the ratio is 20 to 25% for vertical holes, and particularly 2% for vertical holes.
3-25%, inclined hole 80-75%, especially 77-75%
Is suitable. Regarding the position, the vertical hole is 1/3 to 2/3 of the outermost circumference of the disk-shaped nozzle,
Columns are suitable. When the opening of the canopy of the container is located at a corner, the vertical hole is preferably located at the center of the container. That is, it is suitable that the direction of the inclined hole into the container is oriented toward the center of the bottom. It is preferable that the inclined holes are provided so as to be uniformly distributed in portions other than the vertical holes of the disk-shaped nozzle, and that the directions thereof are provided so as to cross the vertical holes inside the container.

These nozzles can be attached to the opening of the container in advance, or can be attached to the tip of a cylinder for liquid pressure feeding, and either nozzle can be used.

In the method of the present invention, when a liquid such as paint or thinner is filled in a container such as an oil can, for example,
This is performed by mounting the nozzle having the above two types of through holes at the tip of the cylindrical nozzle communicating with the liquid storage unit or the opening of the canopy of the container, and then feeding the liquid under pressure to fill the container. The goal is achieved.

[0012]

According to the present invention, when filling a container such as a petroleum can with a liquid such as paint or thinner, by using the nozzle having the above two types of through holes, the liquid filled in the container can be removed from the bottom wall or the like. No bouncing occurred, and sagging outside the opening was also prevented.

[0013]

EXAMPLES Examples and comparative examples according to the present invention will be described. Example 1 A nozzle (note 1) was attached to an opening (diameter 40 mm) at the corner of a canister (capacity: 16 liters, square can). The paint was pumped from the paint tank and filled into a petroleum can via a nozzle (Note 1). As a result, the liquid did not splash off the bottom wall or the like and scattered outside, and dripping was prevented outside the opening. Note 1: A nozzle with a diameter of 40 mm and a thickness of 2 mm. A vertical hole with an inner diameter of 2.5 mm is provided on one half of the outermost circumference (eight pieces), and the other is inclined by 15 degrees and has an inner diameter of 2.5 mm. , One, six, twelve, nine (from the center) to the remaining (the outermost peripheral portion). Comparative Example 1 A nozzle (Note 2) was attached to an opening (diameter: 40 mm) at the corner of a petroleum can (capacity: 16 liters, square can) canopy. The paint was pumped from the paint tank and filled into a petroleum can via a nozzle (Note 2). As a result, the liquid rebounded from the bottom wall or the like and scattered outside, and dripping occurred outside the opening. Note 2: A nozzle with a diameter of 40 mm and a thickness of 2 mm. A vertical hole with an inner diameter of 2.5 mm is 1, 6 or 12 from the center.
, 18 pieces (the remaining portion of the outermost circumference).
