包装体と包装体の製造方法Package and manufacturing method of package

　本発明は被包装物を空気緩衝材とシュリンク包装材とで包み込んだ包装体と、この包装体の製造方法に関するものである。 The present invention relates to a package in which an object to be packaged is wrapped with an air cushioning material and a shrink wrapping material, and a method for manufacturing the package.

　従来から熱収縮フィルムからなるシュリンク包装材で被包装物を包み込んで包装体を得る技術としては、例えば特許文献１では、二つ折りの帯状にして繰り出される熱収縮フィルムの上フィルム部と下フィルム部とが重ね合わされて、熱収縮フィルムの折り部の位置とこの折り部に直交する溶断辺からなる直交辺の位置とで上フィルム部と下フィルム部とが連続するシュリンク包装材を用いるようにした点が示されている。 2. Description of the Related Art Conventionally, as a technique for wrapping an object to be packaged with a shrink wrapping material made of a heat shrinkable film to obtain a package, for example, in Patent Document 1, an upper film portion and a lower film portion of a heat-shrinkable film fed out in a two-fold band shape are disclosed. Are superimposed, and the shrink wrapping material is used in which the upper film portion and the lower film portion are continuous at the position of the folded portion of the heat-shrinkable film and the position of the orthogonal side composed of the fusing side orthogonal to the folded portion. Points are shown.

　そして、この特許文献１では、シュリンク包装材の折り部と直交辺との除く辺側から上フィルム部と下フィルム部との間を開いて、その間に台紙と被包装物を配置し、上フィルム部と下フィルム部での開放されている部分を、線状のヒートシーラーを用いて台紙の辺に沿って溶着するとともに、この溶着部分に沿った位置で余剰のシュリンク包装材を溶断して、台紙及び被包装物を未収縮のシュリンク包装材で覆うようにしている。さらに未収縮のシュリンク包装材で台紙及び被包装物を覆ったものをヒーターに通して、シュリンク包装材が熱収縮することで包装体が得られるものである。 In this Patent Document 1, the space between the upper film portion and the lower film portion is opened from the side other than the folded portion and the orthogonal side of the shrink wrapping material, and the mount and the object to be packaged are arranged therebetween. The part and the open part of the lower film part are welded along the side of the mount using a linear heat sealer, and the excess shrink wrapping material is blown off at the position along this welded part, The mount and the article to be packaged are covered with an unshrinkable shrink wrapping material. Furthermore, the package body is obtained by passing the uncovered shrink wrapping material covering the mount and the article to be packaged through a heater and thermally shrinking the shrink wrapping material.

　また、被包装物を包み込む包装シート自体に緩衝機能を有するものを用いて包装体を得るようにする工夫が、特許文献２、３、４に示されている。これら文献では、独立した多数の気泡を有する合成樹脂製シートの平坦面側に熱収縮性合成樹脂シートを貼り合わせてなる包装材を用いている。そして、この包装材で被包装物を包んだ後に加熱して熱収縮性合成樹脂シートを熱収縮させるようにしている技術が示されている。 工 Further, Patent Documents 2, 3, and 4 disclose devices for obtaining a package using a packaging sheet itself that has a buffering function for wrapping an article to be packaged. In these documents, a packaging material is used in which a heat-shrinkable synthetic resin sheet is bonded to the flat surface side of a synthetic resin sheet having a large number of independent air bubbles. Then, there is disclosed a technique in which the object to be packaged is wrapped with the wrapping material and then heated to thermally shrink the heat-shrinkable synthetic resin sheet.

　また、特許文献５にあっては、建築用板材を胴巻き風に熱収縮したシュリンク包装材によって取りまとめるとともに、建築用板材の木端の加工部分を保護するために、シュリンク包装材の内側に、その建築用板材の長さ方向に沿った空気緩衝部を位置させる技術が示されている。 Also, in Patent Document 5, the building plate material is gathered by a shrink wrapping material that has been thermally shrunk in a trunk wind, and the shrink wrapping material is provided inside the shrink wrapping material in order to protect a processed portion of a wooden end of the building plate material. A technique for positioning an air buffer along the length of a building plate is shown.

　また、特許文献６には、平板状の熱収縮性フィルムと多数の凹凸を有する非収縮性凹凸フィルムとを重ね合わせて非収縮性凹凸フィルムの凸部の周縁部を平板状の熱収縮性フィルムに溶着してシュリンク包装材を設け、このシュリンク包装材で被包装物を覆って外部から熱を加えることにより平板状の熱収縮性フィルムを熱収縮させる点が示されている。 Further, in Patent Document 6, a flat heat-shrinkable film and a non-shrinkable uneven film having a large number of unevenness are superimposed on each other to form a flat heat-shrinkable film on the periphery of the convex portion of the non-shrinkable unevenness film. In this case, a flattened heat-shrinkable film is thermally shrunk by applying a heat from the outside by covering the object to be packaged with the shrink-wrapping material.

　また、特許文献７にあっては、細かな気泡を内側に備える網状プラスチック発泡体と熱収縮性プラスチックフィルムとを貼り合わせてシュリンク包装材を構成し、このシュリンク包装体で前記網状プラスチック発泡体が内側となるようにして被包装物を包み込んでから加熱をし、この加熱によって熱収縮性プラスチックフィルムを熱収縮させる点が示されている。 Further, in Patent Literature 7, a shrink wrapping material is formed by laminating a reticulated plastic foam having fine bubbles inside and a heat-shrinkable plastic film, and the reticulated plastic foam is formed by the shrink wrapping body. It is shown that the object to be packaged is wrapped so as to be on the inside and then heated, and the heat shrinks the heat-shrinkable plastic film by this heating.

　この特許文献７の技術では、被包装物とシュリンク包装材との間に網状プラスチック発泡体が位置することで、被包装物とシュリンク包装材との間に閉じた空気層ができて、緩衝効果が高められるようにしている。 According to the technique of Patent Document 7, since the reticulated plastic foam is located between the object to be packaged and the shrink wrapping material, a closed air layer is formed between the object to be packaged and the shrink wrapping material. Is to be enhanced.

　上述した特許文献２、３、４に示されているような多数の気泡を有する合成樹脂シートに熱収縮性のシートを貼り合わせて一体とした包装材、また特許文献６に示されている平板状の熱収縮性フィルムに非収縮性凹凸フィルムを貼り合わせにより一体にした包装材、そして特許文献７に示されている網状プラスチック発泡体に熱収縮性プラスチックフィルムを貼り合わせして一体とした包装材は、これらの包装材を用いて被包装物を包み込みし、加熱することで熱収縮性フィルムの部分が熱収縮して、被包装物の周りに空気層を形成して緩衝性を備える包装体を得ようとするものである。 A packaging material in which a heat-shrinkable sheet is bonded to a synthetic resin sheet having a large number of cells as shown in Patent Documents 2, 3, and 4 described above, and a flat plate shown in Patent Document 6 Packaging material in which a non-shrinkable uneven film is integrated by laminating a heat-shrinkable film in a shape, and a heat-shrinkable plastic film is integrally bonded to a reticulated plastic foam disclosed in Patent Document 7 The material wraps the object to be packaged using these packaging materials, and heat-shrinks the heat-shrinkable film portion by heating, forming an air layer around the object to be packaged and providing a cushioning property. It is to get the body.

　しかしながら、最外表面側にシュリンク包装材（熱収縮性フィルム）が位置するように上記包装材で包んだ後に、例えば特許文献１で示したように前記包装材の外辺同士を繋ぎ合わせる際、非収縮性フィルムや特許文献７での網状プラスチック発泡体を介在させた状態で溶着しなければならず、包装材の外辺同士の繋ぎ合わせが非常に困難である。 However, after wrapping with the above-mentioned wrapping material so that the shrink wrapping material (heat-shrinkable film) is located on the outermost surface side, for example, when joining the outer sides of the wrapping material as shown in Patent Document 1, Welding must be performed with a non-shrinkable film or a reticulated plastic foam in Patent Document 7 interposed, and it is very difficult to join the outer edges of the packaging material.

　また、特許文献６に示された技術では、包装材が予め直状の膨らみ部分を備えたものであるので、被包装物の大きさに応じてその包装材を溶断すると多くの膨らみ部分から空気が抜け出てしまうという不具合がある。 Further, in the technique disclosed in Patent Document 6, since the packaging material is provided with a straight bulging portion in advance, if the wrapping material is blown off according to the size of the article to be packaged, air will flow from many bulging portions. There is a problem that it comes off.

　また、特許文献５に示された技術では、部分的に空気緩衝部を位置させるものであるので、包装体の外面全面で緩衝作用を得ることができないという問題がある。 技術 Further, in the technique disclosed in Patent Document 5, since the air buffer is partially located, there is a problem that the buffer function cannot be obtained on the entire outer surface of the package.

　本発明者にあっては、緩衝機能を有する部材と熱収縮フィルムとを一体にせず、被包装物を緩衝機能を有する部材で包み込んでから、シュリンク包装材で全体を覆うようにすることで、従来のようにシュリンク包装材の辺部を溶着して貼り合わせが可能となり、加熱を行なってそのシュリンク包装材を熱収縮させることが可能となる点に着目した。 In the present inventor, without integrating the member having a buffer function and the heat shrinkable film, and wrapping the article to be packaged in a member having a buffer function, by covering the whole with a shrink wrapping material, The inventors focused on the point that the sides of the shrink wrapping material can be welded and bonded as in the related art, and the shrink wrapping material can be thermally contracted by heating.

　そこで、本発明は上記事情に鑑み、包装体の最外表面をシュリンク包装材とし、シュリンク包装材の辺部を溶着して内部に緩衝機能を有する部分を形成することを課題とし、熱収縮したシュリンク包装材で包まれていて緩衝機能を有する包装体を得ることを目的とする。 In view of the above circumstances, the present invention has been made to provide a shrink wrapping material for the outermost surface of a package, to form a portion having a buffer function inside by welding the sides of the shrink wrapping material, and to perform heat shrinkage. An object of the present invention is to obtain a package that is wrapped with a shrink wrapping material and has a buffer function.
