Abstract

PROBLEM TO BE SOLVED: To prepare a flowerpot enabling the easy processing with simple tools for forming a drain opening to any one even if a container is made of plastic, porcelain or glass and to provide a method for producing it. SOLUTION: For recycling a bottomed container 1 of plastic, porcelain or glass as a flower pot, a drain opening 3 is formed on a part of the bottom face 2 of the bottomed container 1 with a grinding stone. At first a circular arc dent part is formed beforehand at a specified position of the outside of the bottom face 2 of the container with a grinding stone, and then a drain opening 3 is formed with the grinding stone from the inside of the bottom face 2 while hot water or heated oil is being poured into the container. Alternatively, at first a circular arc dent part is formed beforehand at a specified position of the outside of the bottom face 2 of the container with a grinding stone, and then a drain opening 3 is formed with a boring grinding stone while hydrofluoric acid is being added dropwise into the dent part.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flowerpot having a drain hole formed in a bottom of a plastic, ceramic, or glass bottomed container, and a method for producing the same.

[0002]

2. Description of the Related Art Many conventional flower pots, such as ceramics and bricks, are made of clay mixed with sand and baked. The container of the flowerpot is generally a truncated cone having an open top, a bottom at the bottom, and a drain at the bottom in order to hold the plant and the earth and sand. Actually, it may be made of a ceramic, glass, plastic, or other container. However, in order to appreciate the one planted in a flowerpot, it is required to have a certain degree of aesthetic appearance. Therefore, there are various types of pottery, such as those having a square bottom and those having a shallow bottom. Many use commercially available products.

[0003] Containers with bottoms, such as ceramics, glass, and plastic, include vases, ornamental vases, various containers with lids, dishes, and the like. It cannot be used as a flower pot. Therefore, bottomed containers cannot be diverted and are often abandoned when they are no longer needed.

[0004] However, conventional flower pots have the disadvantage that they are expensive because they are pottery. In addition, bottomed containers such as plastic, ceramics or glass, for example,
I want to process vases, tableware, decorative plates, other bottomed containers, bottles, etc. well and use them as flower pots. However, processing such as drainage is difficult, and it can not be easily made by amateur hands. Preparing the apparatus has the drawback that it is expensive and it is difficult to divert another container to a flowerpot.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a plastic, ceramic or glass bottomed container,
An object of the present invention is to provide an inexpensive flower pot which can be easily processed by a simple device, and which can be easily processed for draining water.

[0006]

SUMMARY OF THE INVENTION The present invention provides a flowerpot characterized in that a drainage hole is formed in a part of the bottom surface of the bottomed container with a drilling tool.

The present invention also relates to a method for producing a flowerpot in which a drain hole is formed in the bottom surface of a bottomed container, wherein an arc-shaped concave portion is previously formed at a predetermined position on the outer surface of the bottom surface of the bottomed container with a grindstone. And then forming a drain hole from the inner surface of the bottom surface with the drilling tool while putting hot water or heated oil into the bottomed container.

The present invention also relates to a method for producing a flowerpot in which a drain hole is formed in the bottom surface of a bottomed container, wherein an arc-shaped concave portion is previously formed at a predetermined position on the outer surface of the bottom surface of the bottomed container with a grindstone. A method for producing a flowerpot, wherein a drainage hole is formed by the drilling tool while hydrofluoric acid is added dropwise to the recess.

As described above, plastics, ceramics,
Alternatively, it can be used for a flowerpot by forming a drain hole in the bottom of a glass bottomed container.

Further, since the ceramic or glass container is easily broken, one surface of the bottom surface of the container is cut into a concave shape and a hole is formed from the opposite side, so that cracking due to hole processing can be prevented.

[0011] Further, since the hole is formed with a grindstone while eroding the hole to be formed with hydrofluoric acid, cracks can be prevented.

[0012]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of a flowerpot according to the present invention, in which a drain hole is formed in the bottom of a plastic, ceramic and glass bottomed container;

(Embodiment 1) A flower pot manufactured according to an embodiment of the present invention is a plastic, ceramic or glass container 1 as shown in FIG. The bottom surface 2 of the container 1 is shown with a drain hole 3 formed therein.

Actually, any material may be used as long as it is a bottomed container made of ceramics, glass, plastic, or the like, but a bottomed container having no drain hole 3 is used, so that there is no hole at the bottom. .

FIG. 2 illustrates the drilling of a bottomed container such as ceramic or glass. First, the outer surface of the bottom surface 2 of the container is cut into an arc-shaped concave portion 4 by a grindstone 5. The grinding stone 5 preferably has diamond cutting edges between abrasive grains.

In the cutting process, the bottom surface 2 is cut by the grindstone 5 while rotating the container 1. As for the cutting amount, about 1/4 to 1/3 of the thickness of the bottom surface 2 is cut into the arc-shaped concave portion 4.

Next, hot water or heated oil is poured into the container 1 and the bottom surface 2 is cut from the inner surface of the container 1 with a grinding wheel 6 having a convex tip or a carbide drill. The machine tool used for these processes is not particularly limited, such as a lathe, a milling machine, and a drilling machine. In these cutting processes, it is necessary to inject grinding water or grinding oil into the cut portion.

(Embodiment 2) As shown in FIG. 3, a flower pot made of pottery, glass, or the like manufactured by the present embodiment is obtained by dropping hydrofluoric acid 7 into the arc-shaped concave portion 4 processed in the above-described embodiment 1. A water draining hole is formed with a grinding wheel 6 for drilling while adding water.

Alternatively, as shown in FIG. 4, first, the arc-shaped concave portion 4 of the first embodiment is cut, and then hydrofluoric acid 7 is injected into the container 1, and the bottom surface 2 is removed from the inner surface. Grinding wheel 6
Alternatively, cutting with a carbide drill. In particular, the glass container is easily cut by injecting the hydrofluoric acid 7.

Ceramic containers require more time for cutting than glass. Simply applying pressure to the grindstone only heats the machined portion, but does not increase the cutting efficiency and tends to crack.

The diameter of the drain hole is about 10 mm to 20 mm, although it depends on the size of the container. The drain hole may be provided at one location substantially at the center of the bottom surface. Particular attention should be paid to the cutting process to match the center positions of the cut portions on the front and back surfaces of the bottom surface. If the center of processing is shifted, cracks and cracks are likely to occur.

As described above, a drainage hole can be formed in a bottomed plastic, ceramic, or glass container to be used as a flowerpot.

[0023]

According to the present invention, even if the container is made of plastic, porcelain, or glass, anyone can easily and easily remove the water, without using any expensive equipment, and easily. It is possible to provide an inexpensive flowerpot in which a drainage hole is formed in the bottom of a ceramic or glass container, and a method of manufacturing the same.
