DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a desired surface on an outer surface of a cylindrical container made of a steel material or an aluminum material by using an organic heat-shrinkable film. The present invention relates to a method for mounting a container suitable for recycling a container of a stock or a waste.

[0002]

2. Description of the Related Art Conventionally, on the front side of a cylindrical container, various characters, symbols, pictures, signs and the like are directly printed on a can body. In addition, when selling a stock in addition to a new cylindrical container, it is necessary to reproduce the printing on the front surface. Also, when recycling a waste container, it is necessary to re-form a desired print on the can body. FIG. 8 shows an example of a conventional method for mounting a new cylindrical container.

[0003] First, a raw steel plate 15 is cut into a predetermined size, and a coating material 16 is applied to the outer surface thereof. next,
A predetermined picture 17 or the like is printed by offset printing. In this example, a printing member 17 is shown in which the same picture is printed on one steel plate 15 on 30 sides. Next, a varnish 18 for surface coating is applied to the surface of the printing member 17, and 30 pictures are cut by a slitter. The cut one-side printed steel plate 18a is rolled as a predetermined cylindrical container,
9 is created. The above pattern is displayed on the surface of the can body 19. Next, the lower lid is attached to the inside of the can body 19, and the contents are put in.
By attaching the upper lid 20, a predetermined printed tubular container 8b is completed.

[0004]

As described above, in the prior art, there is no particular problem in the case of a new container, but in the case of this mounting method, the pattern or the like printed on the surface of the cylindrical container is not. It becomes fixed and cannot be changed without permission. Further, in the case of a stock product, if the stock period is long, the printing on the front side is faded (blurred), and the appearance quality as a new product cannot be maintained. However, the prior art does not allow for easy processing in that case. If forced to do so, the printing on the surface of the container would be removed by some means, such as a solvent, and the cans would be crushed and the metal would be used for another purpose, but this would be expensive and ultimately the regeneration would not be possible. Can not. Therefore, the conventional method is extremely uneconomical.

On the other hand, in the case of recycling waste products, first, as shown in FIG. 9, the printed matter on the surface of the printed cylindrical container 8b is removed by using an expensive technique or the like, and the printed material is removed into a plain can body. After that, the can body has to be disassembled and divided into a steel part 22 and an aluminum part 23 (upper lid 23a, lower lid 23b) and each of them is sent to a reuse process. These are used for low-level recycled products. It's just

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and enables a printed material such as a desired pattern to be efficiently and closely attached to the surface of a can body. It is an object of the present invention to provide a method of mounting a container on which the stock is extremely easy to recycle, and the waste can be easily regenerated at low cost, and the cost can be reduced.

[0007]

The present invention, in order to achieve the above object, comprises means having the following technology. First, a tubular container is covered with an organic heat-shrinkable film subjected to plateless printing or gravure printing from the back side, and the film is shrinked and fitted into the tubular container. Further, in this mounting method, the cylindrical container is a cylindrical body or a polygonal cylindrical body. Next, the organic heat-shrinkable film is a film of an organic thin film of polyethylene and / or vinyl chloride. Thus, the organic heat-shrinkable film is printed from the back side with the necessary characters, symbols, patterns, and markers, and if necessary, is coated with an opaque ink or opaque film on the back side. It is. Still further, the opaque ink may be formed on the back surface of the film in order of white, white, and silver. Further, the organic heat-shrinkable film to which the opaque ink is applied is used for regenerating a new or stock can and the discarded cylindrical container.
Alternatively, instead of applying the opaque ink to the back surface, an opaque film may be attached.

[0008] The organic heat-shrinkable film printed by using a computer is cut one by one and formed into a tubular shape that can be inserted into a can body. After loosely inserting this tubular organic heat-shrinkable film into the completed plain tubular container (can body),
These are put into a shrink device. The organic heat-shrinkable film is shrunk and previously fitted and integrated on the surface of the can body. As described above, a cylindrical container on which a desired pattern or the like is mounted is completed. For stock items, a printed tubular organic heat-shrinkable film is loosely inserted into a cylindrical container having a shrink-wrapped outer cover, and shrink processing is performed. Further, by applying opaque ink to the backing of the organic heat-shrinkable film, the appearance of existing prints can be completely eliminated from the surface, so that the appearance quality can be improved. Further, the shrinkable film is efficiently separated from the can body by applying heat to the cylindrical container that has become waste, and the time required for the regeneration treatment of the can body can be greatly reduced.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the method for mounting a container of the present invention will be described in detail with reference to the drawings. As shown in the flow chart of FIG. 3, first, using a computer 1 (personal computer) (FIG. 1), a design such as a desired character, symbol, picture, design, or sign is edited and converted into data (step 10).
0). Next, as shown in FIG. 1 and FIG. 2, the data design is printed on an organic heat-shrinkable film 2 (hereinafter, referred to as a shrink film 2) (step 101). Note that, as the shrink film 2, a film of an organic thin film such as polyethylene or vinyl chloride is used. Although there are various types of printing, omnias printing and gravure printing are employed as shown in FIG. As described above, a predetermined design is printed on the shrink film 2. In this way, printing is performed using the computer 1 and the gravure (step 102). In this example, as shown in FIG. 2, the printed film 3 is formed continuously. next,
The continuously formed printed film 3 is cut into a predetermined size (step 103), and a single printed film 3a is manufactured as shown. Next, the printed film 3a is formed into a tubular shape to form a tubular body 4 (step 104). A desired design is displayed on the surface of the cylinder 4. The inner diameter of the cylindrical body 4 is larger than the outer diameter of the completed plain cylindrical container 5. For example, if the outer peripheral length of the cylindrical container 5 is a, the inner peripheral length of the cylindrical body 4 Is 1.01 times to 1.
It consists of about 06 times. 1.01 to 1.06
Corresponds to the contraction rate of the cylindrical body 4 and is appropriately set according to the size of the cylindrical container 5, the material of the shrink film 2, and the like.

Next, as shown in FIG. 2, the cylindrical body 4 is loosely inserted into the cylindrical container 5 (step 105). Next, the cylindrical container 5
The container with the cylindrical body 4 loosely inserted therein is put into the shrink device 6, for example, by a conveyor 7 or the like (step 10).
6) The cylindrical body 4 is heated at 80 to 170 ° C. for 5 to 60 seconds to be thermally contracted (step 107). From the above,
The cylindrical body 4 is fitted on the outer surface of the cylindrical container 5 (step 10).
8) The printed container 8 of the final product is completed (step 109). By setting the dimensions of the cylindrical body 4 in accordance with the shrinkage ratio, the cylindrical body 4 is tightly integrated with the outer periphery of the cylindrical container 5 and printed as shown in FIGS. The container 8 is completed.

FIG. 4 is a block diagram showing an outline of a process of performing omnious printing using the computer 1. First, in this example, a Macintosh personal computer (MAC) 9a having a Macintosh personal computer (MAC) 9 and a magnet optical disk drive 10 (MO drive) is used as the computer 1. These are via a hardware HUB 11 having a plurality of ports for connecting an Internet cable to the MAU 1.
2 The MAU 12 is hardware used for high-end equipment such as omnias printing, and switches the network system. Through the digital process by the computer 1, a design such as a desired pattern is converted into data. As shown in FIG. 4, the omnias printing 13 is performed based on the digitized design. Also, gravure printing 14 is performed via plate making. As shown, a color copy 25 is connected to the HUB 11 via an interface 24 (IF), so that a color copy of a desired design can be obtained.

In the above embodiment, as shown in FIG. 5, a cylindrical body 4 having a predetermined design printed thereon is shrunk and fitted on the outer surface of a completed cylindrical container 5.
On the other hand, if the printed container 8 fitted with the cylindrical body 4 having a predetermined design is stocked for a long period of time, the printed portion will be discolored, and the appearance quality as a new product cannot be maintained. In order to maintain the appearance quality, it is necessary to perform extremely complicated work in the conventional technology as described above. However, in the present invention, the new cylinder 4 is inserted into the stocked printed container 8 and shrink-treated in the same manner as described above, so that the cylinder 4 can be regenerated with high efficiency and low cost. In addition, when a request is made during printing to change to a printed sheet with a different design, a cylindrical body 4 with a different design is created, and this is loosely inserted into the printed container 8 of the stock, and shrink treatment is performed. This makes it easy to respond.

However, when another cylinder 4 is loosely inserted into a stock or the like to perform a shrinking treatment, a design that has already been printed may be seen from the surface. In order to prevent this, use is made of a cylinder body 4 having a back surface coated with opaque ink or the like. In this example, a shrink film printed with opaque ink is used to correspond to opaque coating. That is, in this case, a computer edits a Sakai-type undersolution (SUS) size design and converts it into data. By providing the opaque lining, the original printed matter of the existing printed container 8 is shielded and cannot be seen from the outside. As described above, it is possible to prevent the quality from being deteriorated due to the fading of the printing of the stock. In addition, the S.P. U. Since the method using the S size is an original method by the inventor Sakai that is actually used by Shrink, the S.S. U. Abbreviated as S method.

FIG. 6 shows a case where the opaque cylindrical body 14 is first fitted into the cylindrical container 5 by shrinking treatment, and then the cylindrical body 4 having a desired design is fitted thereon by shrinking treatment. As shown in FIG. 7, opaque printing (white, white, silver) is applied to the back surface of the shrink film on which the desired design is printed on the back surface to form a cylindrical body 4 a, which is loosely inserted into the cylindrical container 5 to shrink. Needless to say, it is also possible to perform treatment and fitting. Further, in the above description, a cylindrical body is used as the cylindrical container, but a polygonal cylindrical body can be used to obtain a printed cylindrical container of the same quality. Further, as an actual example, a list of shrink sizes is as shown in Table 1.
