Description

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 packaging 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。  Conventionally, as a technology for obtaining a package by wrapping an article to be wrapped with a shrink wrapping material made of a heat-shrinkable film, for example, in Patent Document 1, an upper film portion and a lower film portion of a heat-shrinkable film that are drawn out in a double-folded band 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 shrink film and the position of the orthogonal side composed of the melted side orthogonal to the folded portion. A dot is 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。  And in this patent document 1, it opens between the upper film part and the lower film part from the edge | side side except the folding part and orthogonal side of a shrink wrapping material, arrange | positions a mount and a to-be-packaged object in the meantime, and an upper film While welding the open part of the part and the lower film part along the side of the mount using a linear heat sealer, fusing excess shrink wrapping material at a position along this welded part, The mount and the package are covered with an unshrinked shrink wrapping material. Furthermore, the packaging body is obtained by passing the base sheet and the article to be packaged with an unshrinked shrink wrapping material through a heater, and the shrink wrapping material is thermally contracted.

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。  Further, Patent Documents 2, 3, and 4 disclose a technique for obtaining a package using a packaging sheet that wraps an article to be packaged and having a cushioning function. 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 bubbles. And the technique which is made to heat-shrink a heat-shrinkable synthetic resin sheet after wrapping an article to be packaged with this packaging material is shown.

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。  Moreover, in patent document 5, while collecting the board | plate material for construction with the shrink wrapping material heat-shrinked in the body wind, in order to protect the processing part of the wooden edge of the board | plate material for construction, the inside of the shrink wrapping material, A technique for positioning an air cushion along the length of a building board 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 irregularities are overlapped to form a flat heat-shrinkable film on the periphery of the convex portion of the non-shrinkable irregular film. It is shown that a shrink wrapping material is provided by welding, and a flat heat-shrinkable film is thermally contracted by covering the article to be packaged with the shrink wrapping material and applying heat from the outside.

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。  Moreover, in patent document 7, the reticulated plastic foam which has a fine bubble inside and a heat-shrinkable plastic film are bonded together, a shrink wrapping material is comprised, and the said reticulated plastic foam is made with this shrink wrapping body. It is shown that heating is performed after the object to be packaged is wrapped in such a manner that the heat shrinkable plastic film is heat shrunk 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。  In the technique of Patent Document 7, a reticulated plastic foam is positioned between the packaged article and the shrink wrapping material, so that a closed air layer is formed between the packaged article and the shrink wrapping material, and a buffering effect is achieved. Has been increased.

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 bubbles as shown in Patent Documents 2, 3, and 4 mentioned above, and a flat plate shown in Patent Document 6 Packaging material in which a non-shrinkable concavo-convex film is integrally bonded to a thin heat-shrinkable film, and packaging in which a heat-shrinkable plastic film is bonded to a reticulated plastic foam disclosed in Patent Document 7 The packaging material is wrapped with these packaging materials, and the heat-shrinkable film part is heat-shrinked by heating, forming an air layer around the packaged material and providing cushioning. Try to get a 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 packaging material so that the shrink packaging material (heat-shrinkable film) is located on the outermost surface side, for example, when connecting the outer sides of the packaging material as shown in Patent Document 1, It must be welded in a state where the non-shrinkable film and the reticulated plastic foam described in Patent Document 7 are interposed, and it is very difficult to connect the outer sides 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 bulge portion in advance, if the wrapping material is blown according to the size of the packaged object, the air from many bulge portions. There is a problem that it comes out.

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。  Moreover, in the technique shown by patent document 5, since an air buffer part is located partially, there exists a problem that a buffering effect cannot be obtained in the whole outer surface of a 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, the member having the cushioning function and the heat shrink film are not integrated, and the article to be packaged is wrapped with the member having the cushioning function, and then covered entirely with the shrink wrapping material, We focused on the fact that the side portions of the shrink wrapping material can be welded and bonded together as in the prior 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。  Therefore, in view of the above circumstances, the present invention has an object of forming a portion having a cushioning function inside by welding the sides of the shrink wrapping material with the outermost surface of the package being a shrink wrapping material, and heat shrinking. An object of the present invention is to obtain a package that is wrapped in a shrink wrapping material and has a buffer function.

（包装体）
つぎに本発明を図示の実施の形態に基づいて詳細に説明する。図中１は包装体で、該包装体１は図１に示されているように被包装物２と、この被包装物２を包み込む空気緩衝材３と、空気緩衝材３によって前記被包装物２を包み込んだ形態のものをさらに包み込むシュリンク包装材４とを備えてなるものである。(Packaging body)
Next, the present invention will be described in detail based on the illustrated embodiment. In FIG. 1, reference numeral 1 denotes a package, and the package 1 is to be packaged 2 as shown in FIG. 2 and a shrink wrapping material 4 for further wrapping the wrapping material 2.

空気緩衝材３は、図２に示されているように被包装物２の外面を覆うようにして被包装物２を包み込んでおり、空気緩衝材３によって被包装物２の外面を覆うように被包装物２を包み込むことによって、この被包装物２の全ての外面の周りに空気層が存在する包装前形態物５を形成している。  As shown in FIG. 2, the air cushioning material 3 wraps the packaging object 2 so as to cover the outer surface of the packaging object 2, and the air cushioning material 3 covers the outer surface of the packaging object 2. By wrapping the article 2 to be packaged, a pre-packaging form 5 is formed in which an air layer exists around all outer surfaces of the article 2 to be packaged.

空気緩衝材３自体は、柔軟な二枚のフィルムの間に空気を封入した畝状空気緩衝部６が、該畝状空気緩衝部６の長さ方向と直交する方向に複数にして並び設けられているものである。そして、被包装物２の外形状に応じて空気緩衝材３が簡単に折れ曲がるように畝状空気緩衝部６それぞれに封入される空気量が調整されており、この畝状空気緩衝部６自体もこの畝状空気緩衝部６の長さ方向に折れ曲がりすることが容易とされている。  In the air cushioning material 3 itself, a plurality of bowl-shaped air cushioning sections 6 in which air is sealed between two flexible films are provided side by side in a direction perpendicular to the length direction of the bowl-shaped air cushioning section 6. It is what. And the air quantity enclosed by each bowl-shaped air buffer part 6 is adjusted so that the air buffer material 3 can be easily bent according to the outer shape of the article 2 to be packaged. It is easy to bend in the length direction of the bowl-shaped air buffer portion 6.

シュリンク包装材４は、加熱により熱収縮する合成樹脂製の熱収縮フィルムからなるものである。そして包装体１にあっては、シュリンク包装材４が加熱によって熱収縮した状態とされており、前記熱収縮によって包装前形態物５の外面全面を覆うようにしてこの包装前形態物５を包み込んでいるものである。  The shrink wrapping material 4 is made of a heat-shrinkable film made of a synthetic resin that heat-shrinks when heated. In the package 1, the shrink wrapping material 4 is in a heat-shrinked state by heating, and the pre-packaging form 5 is wrapped so as to cover the entire outer surface of the pre-packaging form 5 by the heat shrinkage. It is what is.

包装体１でのシュリンク包装材４は、上述したように熱収縮して包装前形態物５の全体を締め付けた状態で包み込んでいる。そして、シュリンク包装材４が包装前形態物５を締め付けた状態で覆っているので、上記空気緩衝材３が被包装物２を包み込んでいる形態が崩れず、空気緩衝材３による緩衝機能が損なわれない。  As described above, the shrink wrapping material 4 in the wrapping body 1 is wrapped in a state in which the whole of the pre-packaging form 5 is tightened by heat shrinkage. Since the shrink wrapping material 4 covers the pre-packaging form 5 in a tightened state, the form in which the air cushioning material 3 wraps the article 2 to be packaged does not collapse, and the cushioning function by the air cushioning material 3 is impaired. I can't.

図において符号７は空気抜き孔を指している。この空気抜き孔７は、シュリンク包装材４が熱収縮するときにこのシュリンク包装材４で囲まれた内部空間から空気を逃がして収縮し易くするための開孔である。  In the figure, reference numeral 7 denotes an air vent hole. The air vent 7 is an opening for allowing the air to escape from the internal space surrounded by the shrink wrapping material 4 when the shrink wrapping material 4 is thermally contracted so that the shrink wrap material 4 is easily contracted.

（包装体の製造方法）
上記構造の包装体１を製造するにあたっては、まず、帯状の空気緩衝材３で被包装物２を包み込む。上述したように空気緩衝材３は、畝状空気緩衝部６がこの畝状空気緩衝部６の長さ方向と直交する方向に複数にして並び設けられている。そして、畝状空気緩衝部６は柔軟な二枚のフィルムの間に空気を封入してなるものであり、前記二枚のフィルムが重ね合わされていて、畝状空気緩衝部６の形成部分及びこの畝状空気緩衝部６の形成部分への空気送り込み部分以外の部分について二枚のフィルムが事前に溶着されている帯状のシートを用い、図示しない空気吹き込み機から空気吹き込み部分を通じて畝状空気緩衝部６の形成部分に空気を送り込みながら空気送り込み部分を溶着にて閉鎖して畝状空気緩衝部６それぞれを封止しているものである。(Method for manufacturing packaging)
In manufacturing the package 1 having the above-described structure, first, the packaged object 2 is wrapped with a band-shaped air cushioning material 3. As described above, the air cushioning material 3 is provided with a plurality of bowl-shaped air cushioning sections 6 arranged in a direction orthogonal to the length direction of the bowl-shaped air cushioning section 6. And the bowl-shaped air buffer part 6 is formed by enclosing air between two flexible films, and the two films are overlapped to form a part of the bowl-shaped air buffer part 6 and this Using a belt-like sheet in which two films are pre-welded with respect to the portions other than the air feeding portion to the forming portion of the saddle-shaped air cushioning portion 6, the saddle-shaped air cushioning portion passes through an air blowing portion (not shown) through an air blowing portion. While the air is fed into the forming portion 6, the air feeding portion is closed by welding to seal each of the bowl-shaped air buffer portions 6.

なお、図示の空気緩衝材３の畝状空気緩衝部６それぞれの形状は太部６ａと細部６ｂとが交互に並んだものを示しているが、空気緩衝材３は一例を示しているものであり、畝状空気緩衝部６は、図示のものに限定されない。  In addition, although each shape of the bowl-shaped air cushioning part 6 of the air cushioning material 3 shown in the figure shows the thick parts 6a and the details 6b alternately arranged, the air cushioning material 3 shows an example. Yes, the bowl-shaped air buffer 6 is not limited to the illustrated one.
