DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a perforator for a liquid storage container for an engine oil, a cleaning liquid, a chemical liquid, an edible oil, a beverage and the like, and a liquid supply apparatus.

2. Description of the Related Art Conventionally, for example, in a gas station, there are many cases in which engine oil packed in a one-liter can is used. However, a large number of empty cans are subject to industrial waste, and there has been difficulty in treating them. Therefore, the use of a so-called pail can containing 20 liters, which is divided into small containers and used, has been started to reduce the discharge amount of empty cans. As for the cooking oil used in restaurants, those packed in cans are widely used. At the time of actual use, it is a fact that a product refilled from a can into a small container in advance is used.

In any of the conventional examples, the work of transferring (subdividing) from a large tank to a small container is troublesome, and improvement thereof has been expected. SUMMARY OF THE INVENTION It is an object of the present invention to provide a punch which can easily and quickly punch a hole in the bottom of a liquid storage container. An object of the present invention is to provide a storage container for a liquid such as oil, which can simplify a transfer operation.

According to the present invention, there is provided a punch for a container for storing a liquid such as oil, which comprises a punch main body and mounting means. The punch body has a pointed top and a divergent shape toward the bottom, and the outer surface of the body reaches the bottom along the outer surface from the top side (from the top or top) of the body. A plurality of guide ridges are formed, and a discharge guide passage is formed between adjacent guide ridges, and the width of each discharge guide passage is gradually increased toward the bottom. The storage container for liquids such as oil according to the present invention includes a gantry, a tank provided on the gantry, and a punch for the storage container attached to an inner bottom surface of the tank. The tank is capable of storing a storage container for liquids such as oil, and has a receiving portion for receiving the storage container at the inner bottom and providing a gap between the inner bottom surface and the bottom of the storage container, The storage container is provided with a supply port for discharging the liquid flowing out of the storage container out of the tank. The perforator can be penetrated with the bottom of the storage container facing inward. The gap is provided with a space capable of temporarily storing a liquid such as oil discharged from a storage container stored in the tank.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 5, a liquid supply device (in the illustrated example, a refueling device 1) includes a gantry 2,
The tank includes a tank 3 located on the gantry, and a punch 4 for a storage container for liquids such as oil, which is attached to the inner bottom surface of the tank. As shown in FIGS. 5 and 6, the gantry 2 has pedestals 2a at four corners, and a space is provided inside. The gantry 2 has a tank 3 fixedly mounted on an upper surface thereof. The storage container 5 for liquid can be stored in the tank 3, and in the storage state, a gap 6 is formed between the inner wall of the tank 3 and the outer surface of the storage container 5 for liquid, and the bottom 5 a of the storage container for liquid is connected to the liquid. A gap 6a is provided between the storage container and the bottom of the storage container. The liquid storage container 5 is placed on a receiving portion 7 fixed to the inner bottom surface of the tank 3 so that a stable storage state can be maintained. Liquid storage container 5
Is a gap 6 between the receiving portion 7 and the inner bottom surface of the tank 3.
a is formed. The liquid storage container 5 is filled with liquids such as various oils and liquid detergents. In the illustrated example, the liquid storage container 5 is a pail for engine oil of an automobile. At the bottom of the tank 3, as shown in FIG.
a and the outlet 3b are open. The supply port 3a is connected to the upper end of a liquid supply pipe (oil supply pipe 8 in the figure) disposed below the bottom of the tank 3, that is, above the gantry 2. The L-shaped oil supply pipe 8 is a flexible pipe, and is rotatable around its upper end (rear end). A valve for opening and closing the inside of the oil supply pipe by operating a valve handle 8a is attached to a tip side of the oil supply pipe 8. By opening the valve handle 8a, engine oil can be supplied from the discharge port at the tip of the oil supply pipe 8 to the subdivision container. The supply port 3a may be a lower part of the tank 3, and may be a lower peripheral wall of the tank other than the bottom part. Reference numeral 3c denotes a lid that covers the upper end opening of the tank 3. The perforator 4 of the liquid storage container includes a perforator body 4a and a means 9 for attaching to the tank 3 as shown in FIGS. The punch body 4a is shaped like a sword having a sharp pointed top, and has a shape gradually expanding toward the bottom, and is a pyramid in FIG. Punch body 4
a is assembled in a plane cross shape by a guide ridge 4b composed of four triangular plates arranged radially outward with the vertex as a center. The guide ridge 4b is
The edge part is the blade part 4b1 over the entire length. As shown in FIG. 2, a discharge guide passage 4c is formed between adjacent guide ridges 4b. The width of each discharge guide passage 4c gradually increases from the top to the bottom. A disk-shaped mounting plate 9 serving as mounting means is fixed to a lower portion of the punch body 4a. A mounting hole 9a is formed in the center of the mounting plate 9, and a tap screw is formed on the inner periphery of the mounting hole. A set screw (not shown) is screwed into the mounting hole 9a from below the upper support plate of the gantry 2, and the punch body 4a is fixed to the inner bottom surface of the tank 3. The mutual relationship between the punch 4, the liquid storage container 5, and the receiving portion 7 will be described. The perforator 4 can penetrate from the bottom 5a of the liquid container 5 to the inside using the sharp top and the blade 4b1 of the guide ridge 4b (FIG. 7).
For this purpose, the punch 4 is provided at the bottom 5 of the liquid storage container 5.
The hole 5a1 can be reliably and smoothly opened in the bottom from below the portion a. As shown in FIGS. 2 and 7, when the punch 4 penetrates through the bottom 5a of the liquid container 5, a square hole 5a1 is formed in the bottom, so that the hole 5a as shown in FIG. The liquid in the liquid storage container flows through the discharge guide passage 4c and the gap 6 at the inner bottom of the tank 3.
a. A gap 6a according to the height of the receiving portion 7
Will change in height. In order to increase the outflow amount of the liquid in the liquid storage container, the height of the receiving portion is increased. As described above, the outflow amount can be adjusted by adjusting the height of the receiving portion 7. In FIG. 7, 5a2 is a hole 5a when a hole is formed.
1 These are rising pieces generated around the inside. Next, a method of using the illustrated oil supply device 1 will be described using an engine oil as an example. The storage container 5 filled with the engine oil is previously put into the tank 3 from the upper end opening. At this time, the storage container 5
Align the center of the bottom with the punch 4. The storage container 5 is gradually lowered to the inner bottom of the tank 3 from the position where the alignment has been performed. Eventually, the bottom of the storage container 5 abuts on the top of the punch 4, and due to the weight of the storage container 5, the sharp top of the punch 4 penetrates the bottom and hits the receiving portion 7. In the process of dropping the tank 3 and abutting against the receiving portion 7, the top of the punch body 4a is first skewered, and a hole 5a1 is formed. In the illustrated example, four holes are successively arranged radially. Blade part 4b of part 4b
It is enlarged while being cut at four places in 1 and finally FIG.
It becomes a square as shown by the chain line. As a result, the engine oil flows into the clearance 6a below the bottom of the storage container through the discharge guide passage 4c of the perforator 4 penetrating into the storage container 5, and accumulates in the clearance 6a. 10 (FIG. 6), and a certain amount of engine oil accumulates in the gap 6. Then, transfer is performed. For the transfer, first, the subdivision container is placed below the discharge port at the end of the oil supply pipe 8, and then the valve is opened by turning the valve handle 8a. Then, the engine oil in the tank 3 passes through the oil supply pipe 8 from the supply port 3a at the bottom, is discharged from the discharge port, and is supplied into the subdivision container. When a predetermined amount of engine oil is supplied into the subdivision container, the valve handle 8
The valve is closed by a. By the same operation as described above, the engine oil in the pail 5 is sequentially divided into small containers.
As described above, the storage container 5 is lowered using its own weight, and the blade 4b1 of the guide ridge 4b of the punch 4 is lowered.
As a result, the hole 5a1 formed in the bottom 5a is enlarged as the hole 5a is lowered, so that no labor is required for the hole forming operation. Further, transfer (subdivision) can be easily performed without soiling the hands by the oil supply pipe 8. The outer shape of the perforator is not limited to the one shown in FIG. 1, but may be a cone or a polygonal cone. For example, as shown in FIGS. 8 and 9, in the puncher 14, the guide ridge 14 b composed of four triangular pyramids is assembled in a cross shape to form the main body 14.
a, and the discharge guide passage 14 is provided between adjacent guide ridges.
c is formed. A mounting hole 19a serving as a mounting means is formed inward (upward) from the center bottom surface of the perforator 14. A tap screw is formed on the inner peripheral surface of the mounting hole 19a. The perforator 14 is a screw that is screwed into the mounting hole 19a from the gantry side and fixed in a state of standing on the bottom surface in the tank. Also in this example, when the main body 14a breaks through the bottom 5a of the liquid storage container, the guide protrusions 14b
Since the hole 5a is smoothly opened by the blade portion 14b1, the hole can be easily opened by the weight of the container itself when the liquid storage container is lowered, and a special hole opening work is unnecessary as in the example of FIG. is there. In the punch 24 shown in FIG. 10 and FIG. 11, a sword-shaped main body 24a is formed in a pyramid, and three triangular plates are arranged radially outward with a vertex as a center. It is assembled in a plane Y-shape by the guide ridge 24b. Other configurations are
Since it is substantially the same as that of the punch 4 shown in FIG. 1, a detailed description will be omitted. 24b is a guide ridge, 24
b1 is a blade of the guide ridge. 24c is a discharge guide passage, 19 is a mounting plate, and 19a is a mounting hole.
In this example, a flat triangular hole 5a1 can be formed in the bottom 5a of the liquid storage container. Also in this example, in the process of lowering the liquid storage container, it is possible to easily make a hole by the weight of the container itself, and the same effect as the example of FIG. 1 is produced. In the punch 34 shown in FIGS. 12 and 13, the main body 34a is formed of a conical body, and the discharge guide passage 3 extending from a position slightly below the vertex (upper vertex position) to the bottom surface on the outer peripheral surface.
4c is formed. Similar discharge guide passages 34c are provided at intervals in the circumferential direction. The guide projection 34b has no blade. 39a is a mounting hole. In FIGS. 9, 11 and 13, rising portions substantially the same as the rising portions 5a2 shown in FIG. 2 are provided inside the periphery of the hole 5a1, but these rising portions are omitted in the drawings. Main body 4, 14, 2 shown in FIG. 1, FIG. 8 and FIG.
4, if the guide ridges 4b, 14b, 24b having the blades 4b1, 14b1, 24b1 are provided, the holes are automatically and very easily and quickly pierced by the own weight of the container itself in the process of lowering the liquid container. Becomes possible. The overall shape of the perforator body is not limited to the one shown in the figure, and the vertex may be a sword-shaped cone, and the guide ridge may be a flat cross shape or a Y shape.
Although the shape of the main body is illustrated, for example, five triangular plate bodies or six triangular plate bodies are radially arranged around the vertices outward at equal intervals, and the overall shape of the main body is changed. The shape is appropriate, such as a polygonal pyramid.

According to the perforator of the present invention, it is possible to easily and reliably pierce the bottom of the container for liquids such as oil, and to gradually enter the container for liquids smoothly by the discharge guide passage. Can be spilled. ADVANTAGE OF THE INVENTION According to the liquid supply apparatus of this invention, the transfer operation | work of a liquid can be performed easily and is convenient.
