Description

Detailed Description of the Invention

The present invention relates to a simple buffer packaging method using the Tetra Classic bag making method.

A tetrahedral container manufacturing method called Tetra Pak (now Tetra Classic), invented by Tetra Pak's Ruben Rousing, is known. This manufacturing method is a manufacturing method in which a tetrahedral container is formed by sealing and cutting a sheet processed into a cylindrical shape at regular intervals and making adjacent seal lines orthogonal to each other. It is known that containers can be manufactured very inexpensively.

Currently, many products are packaged, transported and sold. In addition to products, many parts that make up the products are packaged and transported between factories. In order to transport products and parts while protecting them from damage, it is important to package them, and many packaging methods and cushioning materials have been considered.

Such packaging for protecting products, parts, etc. is mainly necessary only during transportation and is often handled as waste after transportation. For example, currently used polystyrene foam needs to be molded for each product and becomes a waste product after transportation, but it is very bulky and is a foam, so its combustion efficiency in incineration facilities is also poor. For this reason, it is desired that packaging for protecting and transporting products be provided at as low a cost as possible, and those with a low environmental impact at the time of disposal are required.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a buffer packaging method which can firstly provide a buffer packaging suitable for an object to be packaged by a simple and inexpensive method, and secondly is not bulky at the time of disposal and has a low environmental load.

In order to solve the above problems, the present invention applies buffer packaging to an article to be packaged by applying a tetraclassic manufacturing method. The tetra-classic manufacturing method is a manufacturing method that can form a tetrahedral container at a very low cost, and a buffer packaging method that applies the manufacturing method can also be provided with a low-cost packaging in the same manner as the tetra-classic manufacturing method.

Specifically, a tetra-classic manufacturing method that forms a tetrahedral container by sealing and cutting a sheet processed into a cylindrical shape at regular intervals and making adjacent seal lines orthogonal to each other. The cylindrical sheet may be in a state where two large and small cylindrical sheets having different diameters are stacked in two layers so as to be concentric. And when only one end is sealed, the article to be packaged is packed in the inner cylindrical sheet, and the other end is sealed.

According to such a packaging method, an air layer is formed between the inner sheet and the outer sheet, and an air buffer packaging can be obtained. In addition, since the sealed and cut ends are narrowed, a large packaged object does not reach the ends, and external force is not transmitted directly. Furthermore, if the size of the article to be packaged is within the inner cylindrical sheet, it can be packaged regardless of the shape of the article to be packaged.

Here, the two large and small cylindrical sheets do not necessarily have to be concentric, do not necessarily have a two-layer structure, and may have a three-layer structure, a four-layer structure, or more. By doing so, it is possible to perform packaging in accordance with an article to be packaged and a transportation situation. By using multiple structures, it is possible to cope with obstacles such as tearing of sheets, and by using different materials for each sheet, it is possible to make a difference in buffer performance.

Furthermore, according to the packaging method of the present invention, a plurality of objects to be packaged can be buffer-wrapped simultaneously. For this purpose, a plurality of separate cylindrical sheets are included in the cylindrical sheet, and a plurality of articles to be packaged are packed in the plurality of independent cylindrical sheets. By doing in this way, many to-be-packaged objects can be included with few packaging materials. In this case, it is not necessary to pack all the objects to be packaged in the independent cylindrical sheet, and there may be a space where nothing is packed for buffering.

Further, the present invention can be packaged for further improving the buffer performance. In the state where one end of the packaging method described so far is sealed, air is optionally injected under pressure, discharged under reduced pressure, or filled with cushioning material in the space divided by the sheet from the other end. By sealing and cutting, the packaged item can be further protected and fixed. For example, in a space packed with packages, the package can be fixed more by discharging air under reduced pressure, and in other spaces, air can be injected under pressure or filled with cushioning material. Further buffering performance can be expected.

Since the simple buffer packaging method described above is basically cushioning by air, the only thing discarded as waste is a cylindrical sheet, the amount of waste discarded is small, and the combustion efficiency in the incineration facility is also low. The environmental impact is small because it is good.

One embodiment of the present invention is shown in FIG. In a tetra-classic manufacturing method in which a tetrahedral container is formed by sealing and cutting a cylindrically processed sheet at regular intervals and making adjacent seal lines orthogonal to each other. The cylindrical sheet may be in a state where the large-diameter cylindrical sheet 1 and the small-diameter cylindrical sheet 2 are stacked in two layers so as to be concentric. And when only one end is sealed, the article to be packaged is packed in the inner cylindrical sheet, and the other end is sealed. In the figure, a perspective view of a tetrahedral cushion packaging in which a package is simplified.

Here, the two large and small cylindrical sheets 1 and 2 do not necessarily have to be concentric, and do not necessarily have a two-layer structure, but may have a three-layer structure in which a cylindrical sheet 3 having a smaller diameter is added. Alternatively, it may be a four-layer structure having a cylindrical sheet having a smaller diameter or more (FIG. 2). By doing so, it is possible to perform packaging in accordance with an article to be packaged and a transportation situation. By using multiple structures, it is possible to cope with obstacles such as tearing of sheets, and by using different materials for each sheet, it is possible to make a difference in buffer performance.

Furthermore, according to the packaging method of the present invention, a plurality of objects to be packaged can be buffer-wrapped simultaneously. For this purpose, as shown in FIG. 3, a plurality of independent cylindrical sheets such as 2A, 2B, and 2C are included in the cylindrical sheet, and a plurality of packages are packed in the independent cylindrical sheets. That's fine. By doing in this way, many to-be-packaged objects can be included with few packaging materials. In this case, it is not necessary to pack all the objects to be packaged in the independent cylindrical sheet, and there may be a space where nothing is packed for buffering.

It is a perspective view which shows 1st embodiment of this invention. It is a perspective view which shows 2nd embodiment of this invention. It is a perspective view in the manufacture process of 3rd embodiment of this invention.
