Abstract

PURPOSE:To strongly bond and fix counter part molding without causing damage to the molding by a method in which a hot-melt adhesive film is formed on the face to be fitted into each other of the counter part molding by double extrusion, both the moldings are fitted with each other, and the adhesive layer is melted by heating. CONSTITUTION:A shaft material 1 is molded by a double extrusion molding, and a hot-melt adhesive layer 3 (e.g., of maleic acid-modified polypropylene, etc.) of a thickness of 20-50mum is formed on the inner surface of the shaft material 1. A pen tip 2 is fitted into the shaft material 1 and heated from outside so that the temperature of the hot melt adhesive layer 3 becomes 150-160 deg.C. When the film 3 is melted and cooled for solidification, the shaft material 1 and the pen tip 2 are strongly bonded and fixed. Since the film 3 of the double extrusion molding 1 is melted and bonded with the counter part 2, strong bonding and fixation of both the counter parts can be attained without causing any damage to the parts.

部材１４を絞めて固定している。(Prior art and object and structure of the present invention) Conventionally, in the manufacture of ballpoint pens, etc., in order to fix a plastic mating member to a continuously extruded plastic member, the plastic mating member is press-fitted to the plastic extrusion member. ing. (Former) When the mating member is metal, the metallic mating member 14 is tightened and fixed as shown in FIG.

（後者） 前者の場合は、外側の部材の内径を内側σ）部材の外径
より多少小さくして圧入するに必要な強度を得ている。(Latter) In the former case, the inner diameter of the outer member is made somewhat smaller than the outer diameter of the inner member σ) to obtain the strength necessary for press-fitting.

しかし、この場合は材質の劣化なＩどとともに、圧入強
度が緩み、往々にして外側部材が抜けてしまうことがあ
り、必要な嵌合強度を得ることは困難である。However, in this case, along with the deterioration of the material, the press-fitting strength becomes loose, and the outer member often comes off, making it difficult to obtain the necessary fitting strength.

後者の場合は、外側の相手部材を強く絞めすぎると、第
６図のように内側のプラスチックペンチツブ１２のイン
キ流通孔１１が基かれてしまうなどの問題点を生ずる。In the latter case, if the outer mating member is squeezed too strongly, problems such as the ink flow hole 11 of the inner plastic pliers tip 12 being blocked as shown in FIG. 6 will occur.

また、通常の接着剤を用いてプラスチック押出部材に相
手部材を接着する場合もあるが、いづれかの部材が通常

。Further, although a mating member may be bonded to a plastic extruded member using a normal adhesive, this method cannot be used if any of the members cannot be bonded with a normal adhesive.

本発明は以上のような従来のこの種、押出成型物に相手
部材を固定する製品の製造方法の問題点を解決しようと
するものである。すなわち本発明は以下述べるように、

融せしめて、両者を固着する構成を有するものである。The present invention aims to solve the above-mentioned problems of the conventional method of manufacturing a product in which a mating member is fixed to an extrusion molded product. That is, the present invention, as described below,
A double extrusion molded product 1 for fitting and fixing the mating member 2 is used, and a film 3 of Hola 1-melt adhesive is formed on the surface of the double extrusion molding 1 on which the mating member 2 is to be fitted and fixed. Then, after combining the two, the film 1 and the non-melt adhesive film 3 are heated and melted to fix the two.

このような構成により本発明は必要な接着強度が容易に
得られ各々の部材に損傷を与えることなく、かつ、大量
生産の可ｉ４Ｂな二重押出成型物に相手部材を嵌合固定
する製品の製造方法を提供しようとするものである。With such a configuration, the present invention can easily obtain the necessary adhesive strength without damaging each member, and can also be used for a product that fits and fixes a mating member to a mass-produced, easy-to-use double extrusion molded product. The purpose is to provide a manufacturing method.

以下図面に記載された本発明方法の実施例について説明
