DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for producing a packaging container,
The present invention relates to an aerosol product using the same and a method of manufacturing and selling the product.

[0002]

2. Description of the Related Art Generally, printing on the surface of a metal can is performed at the time of can making. In other words, metal slag is squeezed into the shape of a can.
Ironing is performed, an inner coat is applied, a base layer is printed on the surface, and characters and figures are provided thereon by offset printing. In this case, a plate is created based on a predetermined design, and the plate is used to perform high-speed printing with an offset printing press for metal cans. Also, the metal sheet before forming is subjected to offset printing in advance, and then
In some cases, the can is formed by welding or winding.

[0003] In addition, when designing the surface of an aerosol product by an individual, the design is created using a personal computer for home use, printed on a sticker or paper with a printer, and attached to a metal can with an adhesive or the like. Sometimes.

[0004]

The offset printing is a suitable means for producing a large number of packaging containers, but it is costly for a small number of containers. In addition, when changing the size of the can, it is necessary to prepare a plate corresponding to the size, which is troublesome and costly. In particular, in the case of aerosol products, even if the size of the can is the same, the required design differs depending on the contents, so that further labor and cost are required. On the other hand, when a printed sticker is attached to a can, the print is faded or the sticker is peeled off when it comes into contact with water or when it is left for a long time. In particular, in the case of aerosol products, the user may use the packaging container by hand, or the sprayed liquid may hang on the surface of the packaging container, so that it is more easily peeled off and faded.

An object of the present invention is to provide a method for easily providing a surface design which does not peel off and does not fade easily on one or a small number of metal cans. Further, it is a technical object of the present invention to provide an aerosol product and a manufacturing and selling method which are easy to change in design and suitable for small-quantity production.

[0006]

According to a method for manufacturing a packaging container of the present invention, characters or graphics are printed on a medium using sublimable ink based on digital data, and the printed medium is printed on a metal surface. The method is characterized in that the ink is sublimated from the medium by heating and heating the metal can and the medium, and the ink is solidified and fixed on the surface of the metal can by overlapping the metal can with the metal can. (Claim 1).

In such a manufacturing method, it is preferable that the printed medium is tightly fixed to the surface of the metal can by winding the printed medium around a metal can and fixing the end with a heat-resistant heat-shrinkable tape. (Claim 2). Further, it is preferable to maintain the temperature of 100 to 180 ° C. for 5 to 15 minutes when heating the metal can and the medium (claim 3).

[0008] The aerosol product of the present invention is characterized in that a valve is attached to the packaging container obtained by any of the above-mentioned production methods, and the packaging container is filled with a stock solution and a propellant.

The method of manufacturing and selling an aerosol product according to the present invention prints a character or a figure by any one of the above manufacturing methods based on digital data created or selected by a customer.
A valve is attached to the obtained packaging container, and a stock solution and a propellant selected by a customer are filled and delivered to the customer (claim 5).

[0010]

The production method of the present invention (Claim 1)
According to the method, a design to be printed is created by digital data and printed on a medium such as paper using a sublimable ink. When printing on a medium, the sublimable ink adheres to the surface of the medium, and a part of the ink penetrates into the medium depending on the material of the medium. However, the ink adhering to the surface of the medium subsequently sublimates as can be seen from the fact that the ink fades when left for a long time. Therefore, when the printing surface of the medium is heated by applying the printing surface of the medium to the surface of the metal can, most or at least a portion of the sublimable ink is sublimated, solidified on the can surface, and fixed on the surface. In the present application, “solidification” means that the ink sublimates into a gas, which is once liquefied on the surface of the metal can to be solid, and that the ink is directly solid. In the case of a metal can with a base layer on the surface,
This is a concept that includes an ink in which a sublimated ink is impregnated in a base layer.

As described above, in the manufacturing method of the present invention, since a medium once printed is fixed on a metal can, a plate as in the case of offset printing is unnecessary, and equipment such as an offset printing machine for a metal can is also unnecessary. It is. Therefore, the design can be easily changed, and a small number of packaging containers having various designs can be efficiently produced. Furthermore, since the sublimable ink fixed on the surface of the can is directly fixed to the surface of the metal can, it has higher durability than the case where a seal is attached to the surface of the can, and can be peeled off over a long period of use. And the fading progresses slowly.

When fixing a printed medium to a metal can,
When a medium such as paper is wound around a metal can and fixed with a heat-resistant heat-shrinkable tape (claim 2), the tape shrinks due to heat at an early stage of the subsequent heating, and the medium and the can surface are firmly adhered. Therefore, when fixing the sublimable ink, bleeding or blurring hardly occurs.

In the case where the heat treatment is performed at a temperature of 100 to 180 ° C. for 5 to 15 minutes (claim 3), even if the metal can is provided with an inner surface coat, the inner surface coat is not affected, and the metal can is not affected. Fixation to the surface is performed firmly.

The aerosol product of the present invention (claim 4)
It is easy to manufacture and suitable for small-lot production of various designs. In particular, for aerosol products, even if the type of metal can is the same, there are many types of stock solutions and propellants. For this reason, it is indispensable to improve the discriminability of characters and figures on the surface of the can. In the aerosol product of the present invention, various appearance designs can be adopted according to the type of the content to be filled, and the design does not peel off and does not easily fade.

In the case of aerosol products, an inner surface coat of an epoxy resin, phenol resin, polyamide, polyethylene terephthalate or the like is provided on the inner surface of the metal can in order to prevent corrosion by the undiluted solution.
Minute heating has little effect on the inner coat.

According to the method of manufacturing and selling an aerosol product of the present invention (claim 5), a container design can be individually created according to a design created or selected by a customer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a method for manufacturing a packaging container, an aerosol product and a method for manufacturing and selling the same according to the present invention will be described with reference to the drawings. FIG. 1 is a process chart showing a method for producing an aerosol product of the present invention, FIG. 2 is a sectional view of a main part of the aerosol product of the present invention, and FIG. 3 is a flowchart showing an example of a manufacturing and selling method of the present invention.

In the manufacturing method shown in FIG. 1, first, a metal can 10 is manufactured (canning step S1). The metal can 10 may be the same as that used for conventional aerosol products.
For example, a metal slag such as aluminum or tin is formed into a cylindrical shape with a bottom by drawing and ironing, and the upper portion is formed by drawing and forming the shoulder portion 11, and the upper end thereof is formed by curling and forming the bead portion 12. Are used. Metal can 1
A top coat (reference numeral 22 in FIG. 2) is previously applied to the 0 surface.
May be provided. The material of the top coat may be a conventionally used material such as a resin. Further, if necessary, an inner coat (reference numeral 24 in FIG. 2) is provided by spray coating or laminating coating of an epoxy resin, a phenol resin, a polyamide, polyethylene terephthalate, or the like. Usually, a certain number of metal cans 10 are kept in stock.

Next, a design of the can surface is created by, for example, a personal computer (hereinafter, referred to as a personal computer) 15 and printed out by a printer 16 (image creation / printing).
Printing step S2). In order to create an image, the image is created directly using image creation software on the personal computer 15, and digital data of an image captured by a digital camera or the like or an image obtained by a scanner is imported to the personal computer 15 and processed. They may be combined. The image is created in the form of a mirror image for fixing. The created design is printed on a sheet-like medium such as paper by ejecting fine particles of ink using a so-called inkjet printer 16 or a laser printer that represents a predetermined image. Thereby, the printed medium 17 is obtained. The image data may be stored in an electronic storage medium and recalled at the next use.

The sublimable ink used in the printer 16 includes various dyes such as disperse dyes, anionic dyes,
Of the cationic dyes, oil-soluble dyes, chelate dyes, etc., those that sublime are used. The medium 17 is not particularly limited. For example, paper, cloth, plastic film, or the like can be used. However, in order to reduce bleeding, it is preferable to use a medium (including a surface-treated medium) suitable for sublimable ink. .

Next, the printed medium 17 is wound around the surface of the metal can 10 so that the printing surface 17a is in contact with the can surface, and fixed (paper winding step S3). At this time, one end of the medium 17 wound around the surface of the metal can 10 is attached to the other end using an adhesive tape 18 having a heat-resistant heat-shrinkable tape as a base material (adhesion step S4). In this state,
The adhesion between the medium 17 and the surface of the can is still low.

Next, the metal can 10 is housed in a heating machine such as an oven 20, an autoclave, or a drier, and
Heat at a temperature of 0 ° C. for about 5 to 15 minutes (heating step S

When the heating further proceeds, as shown in FIG.
The sublimable ink 21 on the surface of the medium 17 sublimates into a gas and adheres to the surface of the metal can. At this time, the gaseous ink solidifies and is fixed on the surface of the metal can 10. The fixed ink 21 is integrated with the surface of the metal can 10 and does not easily come off. In addition, the code | symbol 23 of FIG. 2 is a metal sheet, and the code | symbol 24 is an inner surface coat.

Next, when the metal can 10 is taken out of the oven 20 and the medium 17 is removed, a printed metal can (packaging container) 25 is obtained (paper removing step S6). Packaging container 25
Is lowered, the aerosol composition comprising the undiluted solution and the propellant is filled into the packaging container 25 by a conventional filling method, and the valve 26 is attached (filling step S7). After filling the undiluted solution into the packaging container 25, the valve 26 is attached,
A propellant may be filled. The valve 26 may be a known one, and the mounting cup is crimped and attached to the bead portion (the reference numeral 12 of the can-making process S1) of the packaging container 25. Thereby, an aerosol product 27 is obtained.
