If you want to make a simple document holder by folding one piece a in half, stacking one piece a on the other, and gluing pieces a and b together at one side 3 adjacent to the folding line 2, as shown in Figure 4. Adhesive structure is adopted. That is, when both pieces a and b are stacked,
One piece a is made to protrude slightly more than the other piece, the protruding part 4 is bent toward the other piece, and a hot plate 5 is applied to the protruding part 4 according to the usual method, so that both pieces a and b are made. are glued together at part 6. Therefore, the end 7 of the protrusion 4 remains floating, making the bonded area unsightly. Therefore, the end portion 7 is usually cut off using a cutter or the like.
[発明の目的]
本発明は、かかる従来の熱接着方法を改良して、簡易に
上記未接着端部を始末することができ、また熱接着部分
の接着強度を高め得る方法を提供することにある。[Object of the invention] The present invention improves the conventional thermal bonding method to provide a method that can easily dispose of the unbonded ends and increase the adhesive strength of the thermally bonded portion. be.
[発明の構成]
即ち、本発明によれば、2片の熱溶融性プラスチックフ
ィルムを1片が他片より若干突出するように重ね、その
突出部を他片の側に折り曲げ、そしてその突出部におい
て1片を他片に熱接着すると同時に熱溶断ンールするこ
とを特徴とするプラスチックフィルムの熱接着方法が提
供される。[Structure of the Invention] That is, according to the present invention, two pieces of thermofusible plastic film are stacked so that one piece slightly protrudes from the other piece, the protruding part is bent toward the other piece, and the protruding part Provided is a method for thermally adhering plastic films, which comprises thermally adhering one piece to another and simultaneously thermally cutting the film.
[実施例コ
本発明においては、第1図に示す如くプラスチックフィ
ルムlを二つ折りし、その1片aを他片すに重ねた際、
両片a、bを接着する部分(即ち、図示の場合は辺3の
部分)において、1片aが他片すよりら若干突出するよ
うにする。この突出は、1片aが突出するように予め加
工したフィルムlを使用するか、またはフィルムlを重
ねた後に他片すの端部を所定幅切断、除去して形成して
よい。次に第2図に示す如く、1片aの突出部4を他片
すの側に折り曲げ、そしてその部分に15で示す熱板を
適用して、熱接着部6を形成すると同時にその上端を熱
溶断シールしてシール部16を形成する。[Example] In the present invention, when the plastic film l is folded in half as shown in Fig. 1 and one piece a is stacked on the other,
At the part where both pieces a and b are bonded (that is, the side 3 in the illustrated case), one piece a is made to protrude slightly from the other piece. This protrusion may be formed by using a film l that has been processed in advance so that one piece a protrudes, or by cutting and removing the end portion of the other piece a to a predetermined width after overlapping the films l. Next, as shown in FIG. 2, the protrusion 4 of one piece a is bent to the other side, and a hot plate 15 is applied to that part to form a thermally bonded part 6, and at the same time its upper end is bent. A seal portion 16 is formed by heat-sealing.
このようにすることにより、第4図に示す端部7に相当
する部分は手でもって容易に除去されることになり、接
着部分が簡易に美しく仕上がる。By doing so, the portion corresponding to the end portion 7 shown in FIG. 4 can be easily removed by hand, and the bonded portion can be easily and beautifully finished.
なお、使用するプラスチックフィルムとしては、従来と
同様に熱溶融性のプラスチックから形成されているもの
であればよく、該プラスチックとしては例えばポリエチ
レン、ポリプロピレン、ポリ塩化ビニル、ポリエステル
などが挙げられる。The plastic film to be used may be one made of heat-melting plastic as in the past, and examples of such plastics include polyethylene, polypropylene, polyvinyl chloride, and polyester.
[発明の作用、効果]
本発明方法によれば、第2図に示す如く熱接着部分が簡
易に美しく仕上がり、また両片a、bの間に書類を入れ
る際には、両片a、bが大きく広がって、書類を入れる
ことが容易となる。[Operations and Effects of the Invention] According to the method of the present invention, as shown in FIG. It expands widely, making it easy to insert documents.
なお、第2図に示す接着構造を採用している場合、その
部分の接着破損は通常第1図に示す矢印方向(即ち、接
着端部)から生じ易い。特に第3図で示す熱接着部6の
下端部26において生じ易い。In addition, when the adhesive structure shown in FIG. 2 is adopted, the adhesive failure in that part usually tends to occur from the direction of the arrow shown in FIG. 1 (i.e., from the adhesive end). This is particularly likely to occur at the lower end portion 26 of the thermally bonded portion 6 shown in FIG.
かかる事態の発生を防止するには、第3図に示す如く、
接着端部において、熱接着部6の部分に非接着部または
弱接着部36を複数熟成すればよい。To prevent such a situation from occurring, as shown in Figure 3,
At the bonded end portion, a plurality of non-bonded portions or weakly bonded portions 36 may be formed in the thermally bonded portion 6 .
即ち、接着端部が断面凹凸状になるように構成すればよ
い。36の部分によって下端部26の破損が停止される
。このように熱接着するには、熱板15の所定部分をノ
コ切刃状に構成すればよい。That is, the adhesive end may be configured to have an uneven cross section. The portion 36 stops the lower end 26 from breaking. In order to thermally bond in this manner, a predetermined portion of the hot plate 15 may be configured in the shape of a saw blade.
