BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container, and more particularly to a packaging container provided with a container body formed from sheet-shaped paper.

[0002]

2. Description of the Related Art As a packaging container, there is a container for packaging a gas stove mat which is a metal foil molded product. The packaging container in this case was composed of a container body and a lid, and both used plastic containers which were molded products of vinyl chloride.
In addition, a transparent plastic container was used so that the gas stove mat could be seen from the outside, and a paper label containing instructions for use and the like was inserted between the lid and the gas stove mat.

[0003]

However, plastic containers have a problem in waste incineration. That is, the calorie burned by synthetic resin is extremely high, and in some cases, undesired gas may be generated, which causes incineration problems. In addition, it is necessary to separate and discard flammable items such as paper labels. Therefore, there is also a problem with disposal, which is insufficient from the viewpoint of environmental issues that have been regarded as important.

Also, a paper label different from a plastic container has been used. However, not only is the cost of the label necessary in addition to the cost of the plastic container, but also the operation of inserting the label into the container is required. It was very expensive. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a packaging container having a container main body which can be adapted to environmental problems and can reduce cost.

Can be printed on the front and back of the container body, eliminating the need for labels.

Also, unlike the plastic container body, paper burns with low calories and is easy to burn, and can be incinerated without generating undesirable gas. Furthermore, even if it is formed so as to conform to the shape of the lower surface of the contents, since it is originally a sheet of paper, it can be easily returned to a sheet of paper, and can be folded down to make it smaller. It can be broken into small pieces of paper or rolled into small pieces, regardless of whether or not to return to sheet-like paper. That is, the disposal space at the time of disposal can be made small. In particular, since the sheet-like paper is formed so as to conform to the shape of the lower surface of the contents, many wrinkles are generated, and the paper can be easily broken along the wrinkles into small pieces of paper.

A second aspect of the present invention is characterized in that the paper of the first aspect includes paper having a waste paper layer. By using paper having a waste paper layer in this way, unlike virgin pulp paper-based paper plates, recycling is promoted,
It can save resources and reduce the amount of waste to deal with disposal problems.

A third aspect of the present invention is characterized in that the paper according to the first or second aspect includes paper having a basis weight of 150 to 250 g / m ² . According to such an invention, it is possible to save resources by using a thin plate instead of a thick plate such as a paper plate that emphasizes strength. According to a fourth aspect of the present invention, the content of the first, second or third aspect includes a metal foil molded body having an opening, and an exposed portion of the container body is printed corresponding to the opening, and the lid is transparent. It is characterized by including a special lid.

[0012]

According to the first aspect of the present invention, the use of a paper container body facilitates disposal and incineration, and can be adapted to environmental issues that are now considered important. In particular, assuming that the lid remains the same as before, the remaining items to be incinerated are plastic containers that are difficult to discard in addition to paper labels that can be separated and disposed of. In the present invention, only the container body made of paper is used.

Further, by using a paper container body which is easy to print, items described on the label can be printed on the container body, and the label can be eliminated. As a result, the cost of the container main body can be reduced as compared with the case of the plastic container main body, and further, there is no need for a label fee, no labor for inserting the label is required, and the cost can be greatly reduced.

According to the second aspect of the present invention, by using paper having a waste paper layer, recycling can be promoted, resources can be saved, and the amount of waste can be reduced to deal with the disposal problem. Further, compared to the case of using only virgin pulp, the cost can be reduced by the amount of the waste paper layer. As a result, in addition to the effect of the first aspect of the present invention, the cost can be reduced while being adapted to environmental problems.

According to the third aspect of the present invention, in addition to the effects of the first or second aspect of the present invention, it is possible to save resources by using a thin paper, and to further reduce costs while adapting to environmental problems. Can be reduced. According to a fourth aspect of the present invention, in addition to the effects of the first, second, or third aspect, the metal foil molded body as the content can be visually observed through the transparent lid and corresponds to the opening of the metal foil molded body. You can also see the printing of the part of the container body that is exposed
The label function can be fully exhibited by printing on the front and back of the container body.

According to a fifth aspect of the present invention, the use of an amorphous-polyethylene terephthalate plastic lid, which is easy to mold and is easy to produce as a recycled product, saves resources and reduces the amount of incombustible garbage to solve the waste incineration problem. Cope with it and become more adaptable to environmental issues.

[0017]

FIG. 1 is an exploded perspective view showing a packaging container and contents according to an embodiment of the present invention, and FIG. 2 is a diagram for packaging contents from the direction of arrow II in FIG. FIG. Referring to FIG. 1 and FIG. 2, the content is a metal foil molded body, and a gas stove mat 101 is shown as an example. Gas stove mat 101
Packaged by a packaging container 103, the packaging container 103
A container body 105 and a lid 107 are provided. Container body 1
Reference numeral 05 denotes a sheet-shaped paper formed to conform to the shape of the lower surface of the gas stove mat 101 as described later. The lid 107 forms a pair with the container main body 105 and covers the upper surface side of the gas stove mat 101.

The gas stove mat 101 has a shape in which an opening 109 is formed at a position corresponding to the burner of the gas stove. A printed portion 111 is provided which performs the described label function. On the other hand, the lid 107 has a thickness of 0.15 m / m to 0.25 m / m.
m transparent amorphous-polyethylene terephthalate lid. Here, polyethylene terephthalate is used because it is easily burned even among plastics and is easily made as a recycled product as compared with vinyl chloride. As a result, it is possible to reduce the amount of hardly combustible garbage and to cope with the waste incineration problem while conserving resources. In addition, the reason why amorphous is used is to facilitate molding.

In such a packaging container 103, as shown in FIG. 2, in a state where the gas stove mat 101 is packaged, the gas stove mat 101 can be viewed from the outside and the printed portion 111 can also be viewed. FIG.
FIG. 4 is a diagram illustrating a front surface of a sheet-like paper before being formed as the container body of FIG. 1, and FIG. 4 is a diagram illustrating a back surface of the sheet-like paper.

Referring to FIG. 3, FIG. 4 and FIG.
The sheet-shaped paper 113 formed as 5 will be described. As shown in FIG. 3, the printing portion 111 is provided on the front surface 115 of the paper 113, as described above, and the instructions for use are printed by gravure printing or the like. Further, a concave line 117 is provided on the back surface side so as to easily form the shape along the lower surface of the gas stove mat 101 without forming natural wrinkles. On the other hand, as shown in FIG.
9 has a printed portion 121 on which other instructions for use such as precautions are printed, and a line 122 protruding from the front side corresponding to the line 117 on the surface 115 is provided. Printing may be performed on the entire surface.

As described above, the use of the sheet-shaped paper 113 makes it possible to perform beautiful printing compared to the case of plastic, and to provide the container body 105 itself with a label function. As a result, in addition to reducing costs by making the container body 105 itself of paper, a label is not required, and a label fee and labor required for inserting a label are not required, so that cost can be significantly reduced. In particular, when the opening 109 exists as in the gas stove mat 101, the exposed portion becomes the printing portion 111, and both the front and back of the container body 105 can be provided with a label function.

FIG. 5 is an enlarged partial sectional view taken along line VV of FIG. Next, the base paper configuration of the paper 113 will be described with reference to FIG. The paper 113 is a thin cardboard weighing about 200 g / m ² , and is an inexpensive cardboard or coated cardboard including the waste paper layer 129. The waste paper layer 129 is sandwiched between the virgin pulp layer 127 and the virgin pulp layer 131. And the virgin pulp layer 1
27, a clay coat layer 123 is formed, a print layer 125 corresponding to the print portion 111 is formed on the clay coat layer 123, and a print transparent varnish layer 126 is formed on the print layer 125. I have. On the other hand, a print layer 133 corresponding to the print portion 121 is formed below the virgin pulp layer 131, and a print transparent varnish layer 134 can be further formed below the virgin pulp layer 131.

As described above, the waste paper layer 129 is included.
This is because recycling is promoted as compared with the case of using paper mainly made of virgin pulp such as a paper plate, resource saving is achieved, and the amount of waste is reduced to deal with the disposal problem. As a result, it is possible to meet the environmental issues that are currently considered important. Further, compared with the case where paper mainly made of virgin pulp such as a paper plate is used, the cost is reduced by the use of the waste paper layer, and the cost can be reduced.

The paper is suitably thick (weighing 260 g / m2).
^{2 to} 350 g / m ² ), it is easy to mold into a shape along the lower surface of the gas stove mat 101, but from the viewpoint of saving resources and further adapting to environmental issues and from the viewpoint of cost reduction, the weighing amount is about 200 g / m ² . Thin paper, weighing about 150
The range of about 250 g / m ² is preferred. The point that such thin paper is used is different from a thick paper plate that emphasizes strength.

FIG. 6 is a plan view of the container body 105 as viewed from above, and FIG. 7 is a sectional view taken along the line VII-VII of FIG. When the sheet-like paper 113 shown in FIG. 3 and FIG. 4 is formed so as to conform to the shape of the lower surface of the gas stove 101, it becomes a three-dimensionally shaped container body 105 as shown in FIG. 6 and FIG. . When formed into such a three-dimensional shape, wrinkles 135 are formed based on the streaks 117 of the paper 113.

Since the three-dimensional container body 105 is made of paper instead of plastic, it can be easily returned to the sheet-like paper 113 by crushing.
They can then be folded down and discarded. Also,
Regardless of whether or not to return to the sheet-like paper 113, it can be broken into small pieces of paper or can be rolled into small pieces. In particular, it can be easily broken by breaking along the wrinkles 135 based on the filaments 135 formed in the three-dimensional shape. By using such a paper container body 105, the space for disposal can be reduced.

Further, unlike paper, paper is unlikely to generate undesirable gas, and as shown in Table 1,
Since the calorific value of combustion is about one third or less, there is an advantage in incineration. Also, amorphous-polyethylene terephthalate does not easily generate undesired gas and has relatively low combustion calories (5500 Kcal / K).
g).

[0028]

[Table 1]

From these results, the paper container body is
Compared with the conventional PVC container body,
It is adapted to environmental issues from the viewpoint of waste incineration. In addition, although the gas stove mat was shown as the contents,
Not only gas stove mats for one burner,
A gas stove mat for a system kitchen stove may be used. Further, the contents need not be a molded article, need not be a metal foil molded article, and need not have an opening.

The lid need not be a transparent lid,
It does not need to be made of amorphous-polyethylene terephthalate plastic, but may be another plastic lid such as vinyl chloride. Further, the paper serving as the container body may be a thick paper, or may be a paper made of virgin pulp without a waste paper layer.

Further, when the contents have an opening, both the lid and the container body may have corresponding openings. Furthermore, printing on the container body does not need to be performed on the front and back of the sheet of paper. For example, when the content is a gas stove mat for a system kitchen stove, a label function may be given to printing on a large back surface even if there is an opening.

Further, since the container body is made of paper, it is easy to print, so that it can be made colorful. In addition, a line is printed and drawn in a visible position on the outside when the container is overlaid.
You can also make it easier to count.
