Description

  The present invention relates to a cutting tool for cutting a bottle container in which a liquid material such as paint, adhesive, ink, oil or the like is stored, and more particularly to a cutting tool capable of cutting a bottle container by rotating the cutting tool itself. .

For example, low viscosity ink such as screen printing ink may be stored in a 1 liter bottle made of vinyl chloride. This bottle container includes a bottomed cylindrical bottle main body and a cap that covers the upper end of the bottle main body. The upper end of the bottle main body is formed in a male screw shape, and the cap is threaded on the upper end. It is composed of a combination. In addition, since the ink contains almost no organic solvent and often needs to be shielded from light, opaque bottles are often used.
The bottle container having the above-described configuration is generally widespread because it is inexpensive and lightweight, but when discarding the bottle container, not only taking out the ink stored therein, but also on the inner surface of the bottle body. It is necessary to remove adhering ink neatly. Therefore, when disposing of the bottle container, the long sticker or the like is used to clean off the ink adhering to the inner surface of the bottle container. However, in such a bottle container, there is a problem that it is difficult to scrape ink in the bottle container. Also, many bottle containers are vertically long, and in this case, there is a problem that it is difficult to scrape off ink adhering to the bottom of the bottle container.
In view of the difficulty of scraping off the ink adhering to the inner surface of the bottle container as described above, conventionally, an operator uses a blade such as a commercially available cutter in a direction (circumferential direction) perpendicular to the axial direction of the bottle container. The container is cut to divide the bottle container into two, and the ink adhering to the inner surface of the bottle container is scraped cleanly.

  On the other hand, conventionally, an apparatus for extracting a liquid content contained in a can such as an 18-liter can has been proposed. This extraction device is provided with a vertically long box body having an upper opening through which a can body is inserted and dropped, and a stopper for receiving the can body is mounted on the inner surface of the middle portion of the vertically long box body, and is directed upward at one corner of the stopper. The cutter is configured to be provided with a cutter that pierces the bottom surface of the can body that is projected and falls and incises the bottom surface of the can body, and a pushing and bending tool that pushes and bends the open section cut by the cutter into the can body. According to the extraction device having such a configuration, the bottom of the can body is opened by the cutter and the pushing / bending tool by the weight of the can body by dropping the can body from the opening at the top of the vertically long box body, The content liquid flows out to the bottom of the vertically long box, and thus the content liquid in the can can be taken out (see, for example, Patent Document 1).

  Conventionally, a can opening device that cuts and opens a can top has been proposed. This can opening device has a configuration provided with a lift that can be raised and lowered, a cutter projecting downward from the lift and a drive mechanism that raises and lowers the lift. According to the can opening device having such a configuration, the lifting platform is raised to the upper limit position, the can body is disposed below the cutter, and the lifting platform is lowered by the driving mechanism, so that the cutter is placed on the top plate of the can body. The top plate can be cut and opened (see, for example, Patent Document 2).

Conventionally, a can opening device for cutting the upper portion of the drum can to open the drum can has been proposed. In this can opening device, a rotator is rotatably attached to the lower side of the ceiling of a frame assembled in a box shape, and a cutter horizontally disposed on the rotator is provided to be movable in the horizontal direction. The mounting plate is provided with a mounting plate. According to the can opening device having such a configuration, the drum can is placed on the placing plate, the cutter is moved inward, the blade edge is inserted into the upper portion of the drum can, and the rotator is rotated. The upper part of the drum can can be incised by rotating the cutter (see, for example, Patent Document 3).

However, in the method of cutting a bottle container using a cutter such as the above-described conventional cutter, there is a problem that an operator needs to be careful so as not to be injured by the cutter and the cutting operation is complicated. .
In addition, when the bottle container is cut using the extraction device described in Patent Document 1 described above, in the case of a bottle container made of a soft material, the bottle container may be pressed and crushed by the cutter, and may not be cut cleanly. There's a problem. Also, even if the incision is successful, the bottom of the bottle container is incised and the ink remaining in the bottle container flows out, but the ink adhering to the inner surface of the bottle container cannot be taken out, and Is bent inward, and the incision is made difficult by removing the ink adhering to the inner surface of the bottle container from the incised portion. Therefore, the extraction device described in Patent Document 1 has a problem that it is difficult to cleanly remove even the ink adhering to the inner surface of the bottle container.

Moreover, in the can opening apparatus described in the above-mentioned Patent Document 2, since the cutter is lowered and the top plate of the object is pushed out, a bottle container made of a soft material such as vinyl chloride is used by using the can opening apparatus. When trying to cut, there is a problem that the bottle container is crushed by the descending cutter and cannot be incised cleanly. In addition, there is a problem that the bottle container must be positioned below the cutter, and the cutting work is troublesome.
In addition, when trying to cut a bottle container using the can opening device described in Patent Document 3 described above, there is a problem that it is necessary to arrange the bottle container at a position immediately below the rotator, which is troublesome.

  The present invention takes the above-described conventional problems into consideration, is easy to work by hand, does not require the trouble of positioning the bottle container, and can easily perform the cutting operation, and can be safely operated. It aims at providing the cutting tool of the bottle container which can improve property. It is another object of the present invention to provide a bottle container cutting tool that can cleanly clean a bottle container made of a soft material and that can cut the bottle container into a shape that facilitates removal of the ink inside.

  In order to solve the above problems, a cutting tool for a bottle container according to the present invention is provided with an exterior part that is rotatably packaged in a circumferential direction with respect to the bottle container, and is provided in the exterior part, incising a side wall of the bottle container And a cutter portion having a cutting blade.

  With such a feature, by attaching the exterior part to the bottle container and rotating the cutting tool and the bottle container relatively, the cutter part turns around the bottle container, and the blade of the cutter part is the wall surface of the bottle container. , The side wall of the bottle container is cut and the bottle container is cut in the circumferential direction. At this time, since the cutter part is provided in the exterior part, the exterior part and the cutter part move integrally, and the cutter part reliably swivels around the bottle container and swivels along the circumferential direction of the bottle container. There will be no departure from the line.

  According to the bottle container cutting tool of the present invention, the bottle container is cut in the circumferential direction simply by attaching the exterior part to the bottle container and relatively rotating the cutting tool and the bottle container. Since it is easy to work and there is no need to align the bottle container, the cutting work can be easily performed. In addition, since the exterior part and the cutter part move together and the cutter part does not come off the swivel line along the circumferential direction of the bottle container, an operator accidentally injured by the blade of the cutter part during the cutting operation. The safety of cutting work can be improved. Moreover, since the wall of the bottle container is incised by moving the blade of the cutter unit along the wall surface of the bottle container, even a bottle container made of a soft material can be cut cleanly. Since the bottle container is cut in the circumferential direction, the cut bottle container has a shape that makes it easy to scrape off the adhering material adhering to the inner surface of the bottle container, and the adhering material adhering to the inner surface of the bottle container is removed. It can be removed easily and cleanly.

  The bottle container cutting tool according to the present invention includes an exterior part that is externally rotatably mounted on the bottle container in a circumferential direction, and a cutter part that is provided on the exterior part and has a blade that cuts out the side wall of the bottle container.
