薄肉化を図った収納容器に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage container in which a plastic container body is covered with a paper sleeve, and the thickness of the plastic container is reduced.
【０００２】[0002]
【従来の技術】従来から、収納容器として市販されてい

クフィルムが貼られたものが知られている。2. Description of the Related Art Conventionally, it is known that a plastic bottle commercially available as a storage container has a paper label or a shrink film attached to its periphery.

形し易く持ちにくいなどの不都合がある。However, recently, from the viewpoint of environmental protection, it has been proposed to reduce the amount of plastics used, and as an attempt to reduce the amount of plastics, research has been carried out to reduce the thickness of plastic bottles. Further, in the case of a thin plastic bottle, there is a disadvantage that it is easily deformed and difficult to hold just by pasting a paper label or a shrink film.
【０００４】そこで，プラスチックボトルの胴部を薄肉
にして周りを紙スリーブで覆ったり，箱型パックの中に
プラスチック容器を格納したものなどが研究開発されて
いる。Therefore, researches and developments have been made on a plastic bottle in which the body portion is made thin and the circumference is covered with a paper sleeve, or a plastic container is housed in a box-shaped pack.

紙スリーブの突起とを嵌合させることにより，両者が固
定されている。For example, in Europe, there is a plastic bottle having a square cross section covered with a paper sleeve.
In this plastic bottle, a recess is formed on the ridge of the box shape, and a projection protruding inside the cylinder is formed on the ridge of the paper sleeve. The paper sleeve and the plastic bottle are fitted together, and By fitting the recess of the plastic bottle and the projection of the paper sleeve, both are fixed.

端部をはめ込んで紙スリーブとプラスチックボトルとを
固定しているものもある。For fixing the paper sleeve to the plastic bottle, a fitting groove extending laterally is formed on the peripheral surface of the body of the plastic bottle, the upper end of the paper sleeve is bent inside the cylinder, and the paper groove is inserted into the fitting groove. In some cases, the folded end of the sleeve is fitted to fix the paper sleeve and the plastic bottle.

く，スリーブとプラスチックボトルとが密着しにくいと
いう問題がある。However, in such a conventional storage container, when a method of forming a recess or a fitting groove in a plastic bottle is adopted, since polyethylene terephthalate is relatively hard, it is formed by blow molding of a heating preform. In this case, it is difficult to form a recess having a small area and a large depth on the peripheral surface of the plastic bottle, and there is a problem that the sleeve and the plastic bottle are difficult to adhere to each other.

および紙片が付着したままになるのでその剥離処理が大
変であるという問題がある。Therefore, it is conceivable that the paper sleeve and the plastic bottle may be glued and bonded together, or hot-melt bonding may be performed, without forming a recess for fixing the sleeve on the peripheral surface of the plastic bottle. However, when the paper sleeve and the plastic bottle are glued and bonded, there is a problem in that the peeling process is difficult because the glue and the paper piece remain attached during recycling.

る。Further, in the case of hot melt, since an adhesive or a thermoplastic resin must be provided inside the paper sleeve, the manufacturing cost of the paper sleeve becomes high, and the heater and temperature for hot melt are increased. Since a control device etc. is required, there is a problem that the equipment becomes large-scale.

適用可能な収納容器を提供することを目的とする。The present invention focuses on such a problem, and makes a container body made of thin-walled plastic to have a certain hardness by means of a paper sleeve, thereby making it easy to hold the entire container and at the same time making the sleeve and the container. It is an object of the present invention to provide a storage container that can reduce the manufacturing time by not using an adhesive for fixing to the main body, and can be applied not only to a circular cross section but also to a rectangular cross section or the like.

る。According to the storage container 1 shown in FIG.
Both ends 4a and 4b of the cardboard 4 are connected by a shrink film 5, and the shrinkage of the shrink film 5 by heat shrinks the thick paper part 4
Since the container body 2 is clamped by the container body 2, even if the body portion 2 of the container body 2 is thin and easily deformed, the rigidity of the cardboard portion 3 makes the storage container 1 itself difficult to deform and easy to hold.

The periphery of the connection part with the b side and the bottom part extends in the horizontal direction, and in addition to having strength against the deformation force from the side, the sleeve 3 has a portion from the top to the bottom of the body part 2a. Since they are held in close contact with each other, the strength of the storage container 1 as a whole is improved, and it is difficult for it to deform. After the liquid as the content is poured, the container body 1 can be separated from the sleeve 3 by deforming the container body 1 from the outside.

い。According to the storage container of claim 2 of the present invention, in addition to the function of the storage container of claim 1, the ridge line portion of the container body of the box-shaped container is stronger than the flat surface portion, and the paper sleeve Since both ends are strongly pulled due to heat shrinkage of the shrink film, the entire storage container is not easily deformed even if the shrink film is located at the ridge. Further, since the flat surface portion of the container body is supported by the paper sleeve and the shape of the entire storage container is stably maintained, it is easy to hold.

Cut the sleeve structure to a desired length with respect to the length of the container body, position the container body inside the sleeve structure, and fill the container body with liquid or gas to heat-shrink the sleeve structure. Then, the periphery of the container body is held and reinforced by the sleeve structure, so that the storage container has a stable shape and is easy to hold. Moreover, since the reinforcement of the container body is completed only by heat shrinkage, the work is easy. Furthermore, since shrink film is only partially used, the amount of plastic used is small. When there are two or more shrink films,
Folding of the sleeve structure is easy.
