The present invention relates to an article packaging method and a package.

[0002]

2. Description of the Related Art Conventionally, as a method of packaging small articles such as cutting tools such as saw blades and drills, hand tools, daily necessities, small articles, stationery and the like, paper coated with an adhesive on one side and blister ( An article was interposed between the films formed by a vinyl chloride system), heat was applied to the blister, the adhesive of the paper was melted, and the paper and the blister were bonded and packaged.

[0003]

[Problems to be Solved by the Invention] In the case of recycling, incineration and disposal, the "paper part" does not have any problem in the regeneration, incineration and disposal. Although it is possible, there is a problem that toxic gas (chlorine gas) is generated at the time of incineration, and a problem that the incinerator is damaged by generating a higher temperature than paper at the time of incineration.

Further, when the blister is discarded, it does not weather like paper (does not return to soil), leaving a problem of environmental pollution.

[0005]

In the article packaging method according to the present invention, a printing ink is applied to at least one of the close contact surfaces of two pieces of paper to be fitted to each other, and the article to be packaged is subjected to the above-mentioned method.
This is a method in which an article is held and packaged between the two pieces of paper by applying heat and pressure in a sandwich state interposed between the close contact surfaces of the two pieces of paper without using an adhesive.

When heating and pressing, only two paper pieces are heated and pressed to avoid an interposed article. Also,
A receiving plate and a heating press plate are used for heating and pressurizing, and further, a recess for escape is formed in the receiving plate at a position corresponding to the interposed article, and two sheets are formed avoiding the interposed article. Heat and press only the pieces of paper.

[0007] Further, the thickness of the two pieces of paper is made different from each other, so that a small thickness piece of paper is made to correspond to the receiving side having the escape recess. The printing ink is weatherable ink that returns to the soil. Alternatively, the printing ink is a non-chlorine resin ink.

A window is opened in one of the two pieces of paper, and packaging is performed so that an intermediate portion of the article to be packaged is exposed from the window.

Next, the package of the present invention has two pieces of paper each having printing ink applied to the mutually contacting contact surfaces, and the article to be packaged W is interposed between the two contact surfaces.
The printing ink is sandwiched and held by integration by heating and pressing without using an adhesive.

[0010] Alternatively, the printing ink is applied to only one of the close contact surfaces having two pieces of paper, and the printing ink is applied by heating and pressing without using an adhesive. An article is held between the two contact surfaces.

Further, the printing ink does not adhere to the article, and the printing ink integrates two pieces of paper with each other in a range excluding the article.

Also, the thickness of the two pieces of paper is made different, one is a flat backing paper, and the other is a surrounding paper in which the position corresponding to the article rises in a convex shape.

Further, it is a weatherable ink in which the printing ink returns to the soil. Alternatively, the printing ink is a non-chlorine resin ink. Then, a window is opened in one of the two pieces of paper, and a middle part of the article to be packaged is exposed.

[0014]

[Action]

A general printing ink can be used by applying heat and pressure without using an adhesive (according to claim 1).
The working environment does not deteriorate. Since the printing ink is used, the reproduction can be performed in the same manner as ordinary paper.
Moreover, when incinerated, no toxic gas such as chlorine gas is generated, and the combustion temperature is not different from that of the paper itself, so that the furnace is not damaged.

According to the second and third aspects, the pressure can be increased strongly, and the two pieces of paper can be firmly integrated. Goods are not damaged.

[0016] According to the third aspect, the packaging can be efficiently performed by raising and lowering the heating press board. In addition, the part corresponding to the article can easily escape, and the other parts can be heated and pressed.

According to the fourth aspect, the article can be packaged more smoothly and efficiently.

According to the fifth or twelfth aspect of the present invention, the waste is returned to natural soil so that the environment is not polluted. (In accordance with claim 6 or 13) When incinerated, it does not emit chlorine gas, does not pollute the atmosphere, and does not damage the incinerator.

According to the seventh or thirteenth aspect, the number of places to be heated and pressed is reduced. In addition, it is convenient to see the articles inside as a package. In addition, both ends of the article are sandwiched and held by two sheets of paper, so that there is no fear of accidental detachment.

Since no adhesive is used (according to claims 8 to 14), it can be handled in the same manner as conventional paper. That is, it can be regenerated, and no toxic gas (chlorine gas) is generated at the time of incineration, and when it is discarded, it is weathered and returned to the soil.

[0021] According to the tenth aspect, since no extra ink adheres to the article, the commercial value is not reduced.
According to claim 11, one can protect the article by preventing it from being bent as a backing, and the other prevents the article from being detached. The other paper can be easily (separately) printed on its front surface such as a product name or a maker name.
