Description
本発明は、肌触りが良く繰り返し塑性変形可能な線状部材と、この線状部材を使用したマスク用保護部材と、繰り返し塑性変形可能な線状部材の製造方法に関する。 The present invention relates to a linear member that is soft to the touch and can be repeatedly plastically deformed, a protective member for a mask using the linear member, and a method for manufacturing the linear member that can be repeatedly plastically deformed.
繰り返し塑性変形させることができる線状部材（針金等）は袋の開口部の結束や植物の支柱への固定等の様々な分野で使用されている。線状部材は芯材として使用している金属を塑性変形させる。しかし、金属は錆が発生する、軽量化が難しい、廃棄に手間がかかる、安全性の観点から食品・医療用製品には使用し辛い、端部の切断面が鋭利になり使用者が怪我するおそれがある等の種々の問題を有する。 Linear members (wires, etc.) that can be repeatedly plastically deformed are used in various fields such as bundling bag openings and fixing plants to struts. The linear member plastically deforms the metal used as the core material. However, metal causes rust, it is difficult to reduce the weight, it takes time to dispose of it, it is difficult to use it for food and medical products from the viewpoint of safety, and the cut surface at the end becomes sharp and the user is injured. It has various problems such as risk.
そこで、近年合成樹脂製の線状部材が開発されている（特許文献1及び2）。この線状部材は上記問題を解消できるだけでなく、様々な分野での使用が想定される。
例えば、マスクを長時間着用していると耳に掛けているゴム紐（耳輪）が耳に食い込んだり擦れたりして痛みが生じることがある。そこで例えば従来シリコーンゴム等の軟質ゴムを筒状に形成して螺旋状に切り込んだり、螺旋状に加工したりしたマスク用保護部材が知られている（特許文献3及び4）。このマスク用保護部材を耳輪に取り付けることで、耳輪が耳に直接触れることがなくなるので痛みを軽減できる。上述した合成樹脂製の線状部材を螺旋状に形成すれば軟質ゴム製のマスク用保護部材の代替品となる可能性がある。
Therefore, in recent years, linear members made of synthetic resin have been developed (
For example, if the mask is worn for a long time, the rubber cord (helix) hanging on the ear may bite or rub against the ear, causing pain. Therefore, for example, conventionally, a protective member for a mask in which soft rubber such as silicone rubber is formed into a tubular shape and cut into a spiral shape or processed into a spiral shape is known (
しかし、上記合成樹脂製の線状部材をマスク用保護部材のようなヒトの肌に直接触れる使い方をする場合には肌触りをよくするために何らかの加工を施すのが好ましい。 However, when the linear member made of the synthetic resin is used such as a protective member for a mask that directly touches human skin, it is preferable to perform some processing to improve the touch.
本発明は、上記のような問題を考慮して、肌触りが良く繰り返し塑性変形可能な線状部材と、この線状部材を使用したマスク用保護部材と、繰り返し塑性変形可能な線状部材の製造方法を提供することを課題とする。 In consideration of the above problems, the present invention manufactures a linear member that is soft to the touch and can be repeatedly plastically deformed, a protective member for a mask using this linear member, and a linear member that can be repeatedly plastically deformed. The challenge is to provide a method.
本発明の繰り返し塑性変形可能な線状部材は、繰り返し塑性変形可能な合成樹脂製の線状の芯材と、前記芯材の周囲を覆う熱融着糸と、前記熱融着糸の周囲を覆うウーリー加工糸とを備えており、前記ウーリー加工糸は前記熱融着糸の接着力によって前記芯材に固定されていることを特徴とする。
本発明のマスク用保護部材は、上記繰り返し塑性変形可能な線状部材が螺旋状に形成されて成ることを特徴とする。
本発明の繰り返し塑性変形可能な線状部材の製造方法は、繰り返し塑性変形可能な合成樹脂製の線状の芯材の周囲を熱融着糸で覆うステップと、加熱しながら前記熱融着糸の周囲をウーリー加工糸で覆うステップと、前記加熱により生じる前記熱融着糸の接着力によって前記ウーリー加工糸を前記芯材に固定するステップを少なくとも備えることを特徴とする。
The repetitively plastically deformable linear member of the present invention includes a linear core material made of synthetic resin that can be repeatedly plastically deformed, a heat-sealed yarn that covers the periphery of the core material, and a perimeter of the heat-fused yarn. The woolly processed yarn is provided to cover the woolly processed yarn, and the woolly processed yarn is fixed to the core material by the adhesive force of the heat-sealed yarn.
The protective member for a mask of the present invention is characterized in that the linear member that can be repeatedly plastically deformed is formed in a spiral shape.
The method for producing a linear member that can be repeatedly plastically deformed according to the present invention includes a step of covering a linear core material made of a synthetic resin that is repeatedly plastically deformable with a heat-sealing yarn, and the heat-sealing yarn while heating. It is characterized by including at least a step of covering the periphery of the woolly processed yarn with the woolly processed yarn and a step of fixing the woolly processed yarn to the core material by the adhesive force of the heat-sealed yarn generated by the heating.
本発明では繰り返し塑性変形可能な合成樹脂製の線状の芯材の周囲をウーリー加工糸で覆い、熱融着糸の接着性を利用してウーリー加工糸を芯材に固定する。仮に熱融着糸を用いずに芯材の周囲をウーリー加工糸で覆っただけの構造の場合、ウーリー加工糸が芯材の表面を滑ってしまい、ウーリー加工糸の位置ずれが生じたり芯材の端部から抜けてしまったりするおそれがある。本発明では熱融着糸でウーリー加工糸を芯材に接着して固定するので位置ずれ等の問題が生じず、繰り返し洗濯することもできる。
芯材として塑性変形可能な線状の部材を使用するので使用者が自在に変形させることができる。
芯材の材料として合成樹脂を使用するので、金属を使用する場合と比較して錆が発生しない、軽量化できる、廃棄が容易、安全性の観点から食品・医療用製品に適している、端部の切断面が鋭利になりにくいという効果も得られる。
最表面がウーリー加工糸で覆われているので肌触りが良いという効果も得られる。
In the present invention, a linear core material made of synthetic resin that can be repeatedly plastically deformed is covered with a woolly processed yarn, and the woolly processed yarn is fixed to the core material by utilizing the adhesiveness of the heat-sealed yarn. If the structure is such that the core material is simply covered with woolly processed yarn without using heat-sealing yarn, the woolly processed yarn slips on the surface of the core material, causing misalignment of the woolly processed yarn or the core material. There is a risk that it will come off from the end of the. In the present invention, since the woolly processed yarn is adhered and fixed to the core material by the heat-sealing yarn, problems such as misalignment do not occur, and the woolly processed yarn can be washed repeatedly.
Since a linear member that can be plastically deformed is used as the core material, the user can freely deform it.
Since synthetic resin is used as the core material, it does not rust compared to when metal is used, it can be made lighter, it is easy to dispose of, and it is suitable for food and medical products from the viewpoint of safety. It is also possible to obtain the effect that the cut surface of the portion is less likely to be sharpened.
Since the outermost surface is covered with woolly processed yarn, the effect of being soft to the touch can be obtained.
繰り返し塑性変形可能な線状部材を螺旋状に形成してマスクの耳輪に取り付けることでマスク用保護部材として使用することができる。使用者が線状部材を伸ばした状態や縮めた状態で保持することができるので使用者の耳の大きさに合わせて調整することが可能になる。
また、従来のようにマスク用保護部材の材料を軟質ゴムにする場合と比較して本発明ではウーリー加工糸が汗を吸収するので耳が蒸れる事態を防止でき、また、ウーリー加工糸が耳の皮膚に柔らかく接触するので使い心地を良好にすることができる。
By forming a linear member that can be repeatedly plastically deformed into a spiral shape and attaching it to the helix of the mask, it can be used as a protective member for a mask. Since the user can hold the linear member in an extended state or a contracted state, it can be adjusted according to the size of the user's ear.
Further, as compared with the case where the material of the protective member for the mask is made of soft rubber as in the conventional case, in the present invention, the woolly processed yarn absorbs sweat, so that the situation where the ear gets stuffy can be prevented, and the woolly processed yarn is used for the ear. Since it comes into soft contact with the skin, it can be used comfortably.
