本発明は、固形ホットメルト接着剤の真空パックおよび
その製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a vacuum pack of a solid hot melt adhesive and a method for producing the same.
ホットメルト接着剤は、加熱して軟化または溶融させた
状態で被着体間に塗布して圧着し、冷却することにより
両被着体を固着させる接着剤であり、接着作業の高速化
と無公害化に最も適した接着剤として、包装、製本、合
板、木工、製靴等において幅広く用いられている。Hot-melt adhesives are adhesives that are heated, softened or melted, applied between adherends, pressed together, and then cooled to bond the two adherends together. As the most suitable adhesive for reducing pollution, it is widely used in packaging, bookbinding, plywood, woodworking, shoemaking, etc.
ホットメルト接着剤としては、フィルム状、棒状、ひも

販売されている。Hot melt adhesives come in various forms, such as film, rod, string, block, powder, strip, and pellet shapes, but block hot melt adhesives are particularly important. Those that are sticky at room temperature are
It is necessary to prevent it from becoming difficult to take out due to adhesion to the inner surface of the container.For this reason, conventionally, it has been stored in a paper box container with a release-treated inner surface and transported in a solid state, or
It's on sale.
第４図は、かかる従来の紙箱容器による包装形態を示す
。FIG. 4 shows a packaging form using such a conventional paper box container.

得るように、シリコーン離型剤が塗布されている。In the figure, a paper box container 41 is made of a substantially rectangular parallelepiped paper box, and a box lid 41b is provided in an opening 41a so as to be openable and closable. Moreover, a silicone mold release agent is applied to the inner surface of the paper box container 41 so that the adhesive rectangular parallelepiped-shaped hot melt adhesive A can be easily taken out.
紙箱容器４１を構成する祇同士の接合はホッチキス等の
止め具や、粘着テープを用いてなされている。The pieces constituting the paper box container 41 are joined together using a fastener such as a stapler or an adhesive tape.
しかしながら、上記従来の包装形態では破損し易い紙を

は所定の接着性能が発揮されないという問題かあ −
った。However, since the above conventional packaging forms use paper, which is easily damaged, as the packaging material, if the paper box is accidentally damaged during opening, scattered paper fragments may adhere to the hot melt adhesive. Or, due to an unforeseen accident such as falling during transportation, the paper box may be damaged and dust on the floor may adhere to the hot melt adhesive, impairing the cleanliness of the hot melt adhesive and causing the coating to deteriorate. Foreign matter may enter the IIN, resulting in poor quality of the final product, or in particularly severe cases.
Is there a problem that the specified adhesion performance is not achieved?
It was.
かかる場合に、ホットメルト接着剤の本来の要求性能を
維持して使用に供するためには、付着した紙片を除去せ
ねばならないが、この除去作業ば長時間を要し、また煩
雑でもあった。In such cases, in order to maintain the originally required performance of the hot melt adhesive and use it, the adhered paper pieces must be removed, but this removal process takes a long time and is also complicated.
また、粘着テープや、ホッチキスを用いて祇同士を接合
する方法では、接合部に多少の間隙が生じることは避け

じてあってはならないことである。In addition, when using adhesive tape or a stapler to join the pieces together, it is inevitable that some gaps will be created at the joint, and dust from the surrounding environment will enter through these gaps and the hot melt adhesive that is the contents will could become contaminated. In particular, when hot-melt adhesives are used in applications where the contents of the package are required to be clean, for example, when used as an adhesive for the sealing part of packaging materials such as food, the adhesive itself is also required to be clean. Therefore, such contamination must never occur.
さらに、従来の包装形態では、内容物と包装容器との間
に隙間があるので、包装体が嵩高になり、保管する上で
広いスペースが必要になる。Furthermore, in conventional packaging forms, there is a gap between the contents and the packaging container, making the packaging bulky and requiring a large space for storage.
さらにまた、前記隙間があるため、運搬時に内容物が包
装容器内で移動し、前記嵩高であることと相まって運搬
が容易でないとともに、破損し易い紙箱容器が包装材料
として用いられているため、内容物の容器内面への衝突
により、容器が破壊されてしまうことすらあった。Furthermore, due to the gaps, the contents move within the packaging container during transportation, and combined with the bulkiness mentioned above, transportation is not easy, and paper boxes, which are easily damaged, are used as packaging materials. In some cases, objects collided with the inside of the container, causing it to be destroyed.

に優れたフィルムを用いることが好ましく、また内容物
の種類および状態を外部から視認し得るようにするため
には透明性に優れたフィルムを用いることが好ましい。The synthetic resin film 12 is not particularly limited in the present invention as long as the inner surface has excellent thermocompression bonding properties and is hard to break. It is also possible to use liM films such as layer laminate films or trilayer laminate films consisting of polyethylene terephthalate (outer layer)/aluminum (middle 31)/polyethylene (inner layer). In addition, in order to prevent the hot melt adhesive from deteriorating, it is preferable to use a film that has excellent oxygen shielding properties, heat resistance, moisture proofing properties, and light blocking properties, and also allows the type and condition of the contents to be visually confirmed from the outside. In order to achieve this, it is preferable to use a film with excellent transparency.
また、用いる合成樹脂フィルム１２の厚みも本発明にお

機械的強度のものを用いることができるが、通常２０〜
３０Ｇ＃ｍの厚さのものが好適である。２０ｐｍ未満の
場合、機械的強度が不足する傾向があるからであり、ま
た３００ａｍを越えた場合、取扱性が劣るからである。Further, the thickness of the synthetic resin film 12 used is not particularly limited in the present invention, and a material with appropriate mechanical strength can be used depending on the weight of the contents, etc., but it is usually 20 to 20.
A thickness of 30G#m is suitable. This is because if it is less than 20 pm, the mechanical strength tends to be insufficient, and if it exceeds 300 am, the handleability is poor.
上記真空引きによる真空パックの真空度は、必ずしも高
い真空度を要求されるものではなく、嵩ばらず、しかも
合成樹脂フィルム１２が外部から圧力を受けた場合に、
パック内の空気の存在に起因して、容易に破裂しない程
度の真空度であればよい。The degree of vacuum of the vacuum pack by the above-mentioned evacuation does not necessarily require a high degree of vacuum, is not bulky, and moreover, when the synthetic resin film 12 receives pressure from the outside,
It is sufficient that the degree of vacuum is such that the pack does not easily burst due to the presence of air within the pack.

り汚染され難く、しかも包装体として嵩ばらない。As explained in detail above, if the vacuum pack according to the present invention is used, the solid hot melt adhesive can be transported in a vacuum-sealed state, so that the solid hot melt adhesive is less likely to be contaminated by dust, etc. The body is not bulky.
″また、合成樹脂製のフィルムにて真空パック詰めした
ので、容器が破損し難いとともに、開封の際に散乱する
包装部材の破片が接着剤に付着することもない。``Furthermore, since the container is vacuum-packed with a synthetic resin film, the container is less likely to be damaged, and fragments of the packaging member scattered when the package is opened will not adhere to the adhesive.
さらに、本発明に係る製造方法によれば、上述の如き効
果を有する真空パックを容易に製造することができる。Furthermore, according to the manufacturing method of the present invention, a vacuum pack having the above-mentioned effects can be easily manufactured.
以上の如く、本発明は優れた特有の効果を奏する。As described above, the present invention has excellent and unique effects.
