ーブの構成を改良することにより、該チューブの扱いを
簡便化するなどを目的に考案されたものである。[Detailed description of the invention] This invention relates to a plastic tube that shrinks when heated, especially a heat-shrinkable plastic tube that covers the entire connection part of a pipe, etc. By improving the structure of the plastic tube, It was devised for the purpose of simplifying the handling of the tube.
近年、ガス管あるいは石油管などパイプの接続部に防食
材として、外周面に熱収縮性プラスチック層、内周面に
接着剤層を有する熱収縮性プラスチックチューブを被覆
することが行なわれる。In recent years, connecting portions of pipes such as gas pipes or oil pipes have been coated with heat-shrinkable plastic tubes having a heat-shrinkable plastic layer on the outer circumferential surface and an adhesive layer on the inner circumferential surface as corrosion protection.
この熱収縮性プラスチックチューブは接着剤層を保護す
るために筒形の離形紙が仮着されており、これを使用す
るには、当然なこととして離形紙を剥がすこととなるが
、このチューブを被着パイプに外挿する前に剥がすと挿
通中に接着剤層が被着パイプに接着するなどしてチュー
ブを所定位置に外挿できないなどの問題がある。This heat-shrinkable plastic tube has a cylindrical release paper temporarily attached to it to protect the adhesive layer, and to use it, the release paper must be peeled off. If the tube is peeled off before being inserted into the adhered pipe, there will be problems such as the adhesive layer adhering to the adhered pipe during insertion, making it impossible to extrapolate the tube to a predetermined position.
このため、外挿後に剥すことも行なわれているが、従来
の離形紙はチューブの内周面長さと同一寸法となってお
り、チューブとパイプとの間隙もわずかであるため、そ
の剥離作業は非常にむずかしいものとなっている。For this reason, peeling is also performed after extrapolation, but conventional release paper has the same dimensions as the inner peripheral surface length of the tube, and the gap between the tube and pipe is small, so the peeling process is difficult. has become extremely difficult.
この考案は、以上の点に留意し、外挿したのちにおいて
も離形紙を円滑に剥離し得る熱収縮性プラスチックチュ
ーブを提供することを目的とする。With the above points in mind, this invention aims to provide a heat-shrinkable plastic tube from which the release paper can be smoothly peeled off even after extrapolation.
以下、この考案をその実施例を示した添付図面に基づい
て説明する。Hereinafter, this invention will be explained based on the accompanying drawings showing examples thereof.

形成したものである。As shown in FIG. 1, the tube A of this invention consists of the inner periphery of a heat-shrinkable plastic tube body 1 made of polyethylene, polyvinyl chloride, polyester, silicone rubber, ethylene, propylene copolymer rubber, etc. An adhesive layer 2 such as a pressure-sensitive adhesive, a heat-activated adhesive, or a mastic adhesive is provided on the surface, and a release paper 3 in the shape of a longitudinal cylinder is temporarily provided on the inner peripheral surface of the adhesive layer 2. One end of the release paper is slightly protruded from the open end 4 of the heat-shrinkable plastic tube body 1, and a take-out portion 5 is formed around the entire circumference of the open end 4.
取り出し部5は一端部のみでなく、両端部に形成しても
よい。The take-out portion 5 may be formed not only at one end but also at both ends.
このチューブAによりパイプ接続部を被覆するには、ま
ず、第1図に示すように、被着パイプPの接続部近くま
でチューブAを外挿し、第2図実線のごとく接着テープ
又は接着剤などで取り出し部5を被着パイプPに固着し
たのち、さらに、同図鎖線のごとくチューブAをa矢印
の方向に移動すると、離形紙3は折曲しながら剥れる。To cover the pipe connection part with this tube A, first, as shown in Fig. 1, extend the tube A close to the connection part of the pipe P to be coated, and use adhesive tape or adhesive as shown in the solid line in Fig. 2. After fixing the take-out part 5 to the adhered pipe P, when the tube A is further moved in the direction of the arrow a as shown by the chain line in the figure, the release paper 3 is peeled off while being bent.
この作用時、取り出し部5が開口4全周に亘って形成さ
れているため、第3図のごとく一部にしか取り出し部が
ない場合のように離形紙3が円滑に折曲せずに剥れない
ということがない。During this operation, since the take-out part 5 is formed around the entire circumference of the opening 4, the release paper 3 does not bend smoothly as in the case where the take-out part is only partially provided as shown in Fig. 3. It never comes off.
この様に離形紙3を剥離すると、接着剤層2は被着パイ
プPの外周面と相対することになり、この状態で熱収縮
性プラスチックチューブ体1を加熱すると、当該チュー
ブは熱収縮し接着剤層2を介して被着パイプPの外周を
完全に被覆する。When the release paper 3 is peeled off in this way, the adhesive layer 2 comes to face the outer peripheral surface of the adhered pipe P, and when the heat-shrinkable plastic tube body 1 is heated in this state, the tube will heat-shrink. The outer periphery of the adhered pipe P is completely covered with the adhesive layer 2.
以上のように、この考案のチューブは、離形紙の端部を
プラスチックチューブ体の開口端から突出させて離形紙
の取り出し部を前記開口端全周に亘って設けた構造とし
たので、チューブを被着パイプに外挿した後でも離形紙
を簡単に剥離することができ、チューブの被着作業が円
滑になる効果がある。As described above, the tube of this invention has a structure in which the end of the release paper protrudes from the open end of the plastic tube body and the release paper take-out part is provided around the entire circumference of the open end. The release paper can be easily peeled off even after the tube is inserted into the adhered pipe, which has the effect of making the work of adhering the tube smoother.
