For example, it is molded in the first injection molding stage, and then the part (4) other than the adhesive part is molded on the adhesive part (3). As a result, a welding line is formed between the adhesive portion (3) and the portion (4) other than the adhesive portion. If necessary, at least the bonding surface of the adhesive part (3) is activated by thermal radiation before the actual bonding process. After that, the adhesive molded member is adhesively bonded to the component by being pressed against the component (5) via the adhesive portion (3) facing the component (5).
Description
【発明の詳細な説明】 接着性成形部材及びその製造方法 発明の背景 1.発明の分野 本発明は、射出成形の技術分野に属し、熱可塑性材料の接着性成形部材及びそ の製造方法に関するものである。 2.従来技術の説明 従来、熱可塑性材料が使用され、射出成形によって成形された成形部材と、熱 可塑性材料又は他の材料から成る他の部材とを、特定の用途のために接合するこ とがある。この場合、接合が行われる二つの面(一方の面は成形部材の表面であ る。)の間に接着剤が挿入され、二つの面が互いに押圧される。 そのために、例えば、前記接着剤を液状にして一方の面に散布したり、接着フ ィルム状にして二つの面の間に置いた後、加熱して活性化させたりする。そして 、特性(材質)が極めて異なる二つの面の間において接合を行う場合には、接着 剤として、粘着力又は結合力による接合工程の終了後に十分な接着が行われるよ うな材料を選択する必要がある。 ところが、適切な位置に適切な量の接着剤を投入するのは困難である。特に、 成形部材の表面が極めて複雑な形状を有している場合は、複雑な形状を有する個 々の部分だけを接合しなければならないので、接着剤を正確に、かつ、正しい方 法によって接合部分にだけ塗布することが困難であり、場合によっては、接合後 に余分な接着剤を除去しなければならないこともある。 例えば、EP−Al−546999に記載されるように、紙、厚紙、熱可塑性 被覆材料等から成る飲料用の容器において、前記成形部材を蓋(ふた)部材とし て使用する場合、前述のような問題が生じる。この種の蓋部材は、必ずしも容器 に溶着することができるわけではなく、接着剤を使用して容器に接合することが 多い。例えば、容器の材料が、蓋部材を溶着するのに適さないものである場合、 又は既に充填(てん)が行われた容器に蓋部材を溶着によって取り付けると容器 の中身が損なわれる恐れがある場合に、接着剤が使用される。 発明の概要 本発明は、熱可塑性材料を射出成形することによって接着性成形部材を成形し 、接着性成形部材と他の部品(接合先の部品)とを容易かつ正確に接合すること ができる接着性成形部材及びその製造方法を提供することを目的とする。 本発明の接着性成形部材においては、接着剤としての接着剤部が一体的に形成 され、該接着剤部と接着剤部以外の部分とは溶着線を介して接続され、両者によ って接着性成形部材が形成される。なお、前記溶着線は、連続した二回の射出成 形工程において、接着剤と別の材料とを、それぞれに対応させて選択された成形 条件で成形することによって得ることができる。 この場合、一体的な接着剤部を備えた接着性成形部材は、複数材射出成形方法 によって成形され、該複数材射出成形方法においては、例えば、まず、接着剤に よって接着剤部が成形され、次に、型キャビティが変更され、一つ以上の射出成 形段階において、接着剤部以外の部分が一種類以上の熱可塑性材料によって成形 される。その結果、前記接着剤部の少なくとも一部分が型キャビティに臨むよう になる。 なお、前記接着剤部を構成する接着剤としては、次の条件が必要になる。 ・常温で固体であること。 ・射出成形が可能であること。 ・射出成形によって、接着性成形部材の他の材料との間に安定した溶着線を形成 することができること。 ・必要に応じて、少なくとも表面が所定の方法で活性化された後に、接着性成形 部材が接合される他の面との間で、接着性又は共有性の結合、すなわち、接着接 合を行うことができること。 これらの条件は、特定の用途に応じて選択されるホットメルト接着剤によって 満たされる。 すなわち、ホットメルト接着剤は、対応する特定の活性化温度に加熱されると 、粘着性が高くなる。そして、この状態において、他の面との間で接着接合が行 われ、その後、活性化温度より低温になると安定化する。前記ホットメルト接着 剤は、通常、基本ポリマー及び接着剤から成るが、可塑剤、抗酸化剤、充填剤等 を含むこともできる。前記基本ポリマーは、ホットメルト接着剤の活性化温度を 実質的に決定する。通常、市販されているホットメルト接着剤においては、基本 ポリマーとしてエチレンビニルアセテートコーポリマー(活性化温度90〜14 0〔℃〕)、ポリアミド(活性化温度120〜180〔℃〕)、又はポリエステ ル(活性化温度150〜210〔℃〕)が使用される。なお、ホットメルト接着 剤によって接着接合が行われる他の面には、通常、接着接合によって引き起こさ れる構造上の変化は見られない。 接着性成形部材の面は、実際の接着接合工程の前に活性化(すなわち、活性化 温度に加熱すること)を行うために、熱、赤外線、超音波、炎、放電又はプラズ マによって処理されるが、特定の用途のためには、二つの面を合わせる前又は合 わせた後に活性化を行うこともできる。この活性化は、他の部品と接着剤部との 間の接着接合にだけ影響を与える。そして、接着剤部と接着剤部以外の部分とは 、射出成形工程によって接続されるので、活性化及び接着接合工程より長く作用 し、結果的に活性化工程とは全く独立している。 このことは、接着剤を従来技術に従って使用した場合に必要とされた一つの条 件が、本発明の成形部材の接着剤部においては不要になることを意味する。すな わち、接着剤と両接着面の材料との間で接着性又は共有性の接続が可能でなけれ ばならず、したがって、接着剤と両接着面との間に同じ活性化が行われなければ ならない、という条件が不要になる。 本発明の一体的な接着剤部を備えた接着性成形部材においては、特に、成形部 材に接着剤をスプレーで塗布した場合と比較して、接着剤部を厚い層状に、例え ば、不均一な厚さを持つ層として形成することが可能になる。 すなわち、接着剤部によって、局部的な粗面、凹凸面等に正確に適合する層が 形成される。また、接着剤部を必ずしも層状にする必要はなく、有形体状にする こともできる。この場合、二つの面が合わされる際に、設定された方法で有形体 状の接着剤部を変形させることができる。 接着性成形部材の接着剤部と接着剤部以外の部分との間に半連続的なストリン グ又はコードを周知の方法によって配設することによって、多数の成形部材を連 結することができる。前記ストリング又はコードは、接着接合のときに取り除か れるか切断される。 さらに、特定の多数の成形部材を連結するために、例えば、シリコン被覆紙ス トリップ上に各接着剤部を成形することができる。この場合、各成形部材は接着 接合前にシリコン被覆紙ストリップから引き剥(は)がされる。また、同様の方 法で、接着剤面以外の表面を備えた紙ストリップ上に成形部材を成形することも できる。 図面の簡単な説明 本発明の実施の形態における一体的な接着剤部を備えた接着性成形部材を、以 下の図面を参照しながら詳細に説明する。 第1a図〜第1d図は本発明の実施の形態における接着性成形部材の製造工程 及び接合状態を示す図である。 第2図は本発明の実施の形態における液状製品用容器の蓋部材として形成され た接着性成形部材の接着剤部側から見た平面図である。 第3図は第2図の接着性成形部材の側面図である。 第4図〜第6図は実施の形態における接着剤部とその使用態様の変形例を示す 図である。 適切な実施の形態の説明 第1a図〜第1d図は、本発明の実施の形態における接着性成形部材の製造工 程、及び該接着性成形部材の他の部品への接着接合を模式的に示す。 第1a図は、第1の射出成形段階における二つの部分から成る射出成形用の金 型10、11の型キャビティ1を通る断面図である。この場合、ホットメルト接 着剤Aによって接着剤部が成形される。金型10、11の材料としては、成形さ れたホットメルト接着剤Aが冷却の際に粘着することがないように、ポリテトラ フルオロエチレン(PEFE)、ポリテトラフルオロエチレンが被覆されたニッ ケル、クロム、又はチタンニッケル合金を使用するのが望ましい。 第1b図は、第2の射出成形段階における二つの部分から成る射出用の金型1 0、12の型キャビティ2を通る断面図である。この場合、第1の射出成形段階 で成形された接着剤部3上に、接着剤Bによって接着剤部以外の部分が成形され る。

Field of the invention The present invention belongs to the technical field of injection molding, and relates to an adhesive molded member made of a thermoplastic material and the same. The present invention relates to a manufacturing method of. 2. Description of the prior art Conventionally, thermoplastic materials are used, and molded parts molded by injection molding Joining with other parts made of plastic material or other materials for specific applications There is. In this case, the two surfaces to be joined (one surface being the surface of the molded part) It Between the two) and the two surfaces are pressed together. For that purpose, for example, the adhesive may be liquefied and sprayed on one surface, or It is made into a film and placed between two surfaces and then heated to activate it. And , When bonding between two surfaces with extremely different characteristics (materials), bond As an agent, sufficient adhesion will be achieved after the joining process by adhesive force or bonding force is completed. It is necessary to select such materials. However, it is difficult to put an appropriate amount of adhesive in an appropriate position. Especially, If the surface of the molded part has an extremely complicated shape, Only the different parts have to be joined, so the adhesive must be correct and correct. It is difficult to apply only to the joint part by the method, and in some cases, after joining Sometimes it is necessary to remove excess glue. For example, paper, cardboard, thermoplastic, as described in EP-Al-546999. In a beverage container made of a coating material or the like, the molding member is used as a lid member. When used as described above, the above-mentioned problems occur. This kind of lid member is not always a container It cannot be welded to and can be joined to the container using an adhesive. Many. For example, if the material of the container is not suitable for welding the lid member, Or, if the lid member is attached by welding to a container that has already been filled, Adhesives are used when the contents of the can be damaged. Summary of the invention The present invention forms an adhesive molded member by injection molding a thermoplastic material. , Easy and accurate joining of adhesive molded parts and other parts (parts to be joined) It is an object of the present invention to provide an adhesive molded member that can be manufactured and a method for manufacturing the same. In the adhesive molded member of the present invention, the adhesive portion as an adhesive is integrally formed. The adhesive portion and the portion other than the adhesive portion are connected via a welding line, and Thus, the adhesive molded member is formed. In addition, the welding line is formed by two consecutive injections. In the shaping process, the adhesive and another material are selected corresponding to each other It can be obtained by molding under the conditions. In this case, the adhesive molding member provided with an integral adhesive part is a multi-material injection molding method. In the multi-material injection molding method, for example, first, an adhesive is used. Thus the adhesive part is molded, then the mold cavity is modified and one or more injection moldings In the shaping step, the parts other than the adhesive part are molded with one or more thermoplastic materials To be done. As a result, at least a part of the adhesive part faces the mold cavity. become. The following conditions are required for the adhesive forming the adhesive section. -It should be solid at room temperature. -Injection molding is possible. ・ By injection molding, a stable welding line is formed between the adhesive molding material and other materials What you can do. ・ Adhesive molding, if necessary after at least the surface has been activated by a predetermined method An adhesive or covalent bond, or adhesive bond, with another surface to which the members are joined. That can be combined. These conditions depend on the hot melt adhesive selected for the particular application. It is filled. That is, when the hot melt adhesive is heated to the corresponding specific activation temperature , Becomes more sticky. Then, in this state, adhesive bonding is performed with the other surface. After that, it stabilizes when the temperature becomes lower than the activation temperature. The hot melt adhesion Agents usually consist of basic polymers and adhesives, but plasticizers, antioxidants, fillers, etc. Can also be included. The base polymer has the activation temperature of the hot melt adhesive. Substantially determined. Usually, in hot melt adhesives that are commercially available, As a polymer, ethylene vinyl acetate copolymer (activation temperature 90-14 0 [° C]), polyamide (activating temperature 120 to 180 [° C]), or polyester (Activation temperature 150 to 210 [° C.]) is used. Hot melt adhesion The other side where the adhesive bond is made by the agent is usually caused by the adhesive bond. No structural changes are seen. The surface of the adhesive molded part is activated (ie activated) before the actual adhesive bonding process. Heating to temperature), infrared, ultrasonic, flame, discharge or plasm However, depending on the specific application, before or after mating the two surfaces, After activation, activation can also be performed. This activation of the other parts and the adhesive part It only affects the adhesive bonding between. And the adhesive part and the part other than the adhesive part Since it is connected by injection molding process, it works longer than activation and adhesive bonding process However, as a result, it is completely independent of the activation process. This is one of the strips required when using adhesives according to the prior art. This means that it is unnecessary in the adhesive part of the molded member of the present invention. sand That is, there must be an adhesive or covalent connection between the adhesive and the material of both adhesive surfaces. Must therefore be done between the adhesive and both adhesive surfaces with the same activation. The condition that it does not become unnecessary. In the adhesive molding member having the integral adhesive part of the present invention, in particular, the molding part Compared to the case where the adhesive is applied to the material by spraying, the adhesive part is thick layered, for example. For example, it becomes possible to form a layer having a non-uniform thickness. In other words, the adhesive part provides a layer that exactly matches the rough surface, uneven surface, etc. It is formed. Also, the adhesive part does not necessarily have to be in a layered form, but has a tangible form. You can also. In this case, when the two faces are mated, the tangent It is possible to deform the adhesive portion of the shape. Adhesive molding A semi-continuous string between the adhesive part and the part other than the adhesive part. A number of molded members can be connected by arranging Can be tied. The string or cord should be removed at the time of adhesive bonding. Be disconnected or disconnected. In addition, for example, silicone coated paper strips can be used to connect a specific number of molded parts. Each adhesive part can be molded on the trip. In this case, each molded member is bonded It is peeled off from the silicon coated paper strip prior to bonding. Also, the same person Can also be used to form molded parts on paper strips with surfaces other than the adhesive side. it can.
