Cellulose fibers are intertwined with each other at the interface with the snap elements formed on the front and back surfaces.
- the snap elements 304 and 302 do not need to be formed over the front and back of the fastener tape 306. Therefore, the snap elements 304 and 302 can be formed only on the front and back surfaces of the fastener tape 306 on the side where the snap elements 304 and 302 face each other, and need not be formed on the opposite side.
- FIG. 7 shows an example in which the paper slide fasteners 402 and 404 according to the present invention are attached to the opening and closing part of the paper bag 400.
- FIG. 8 is a sectional view taken along line Z-Z ′ in FIG. Referring to FIG. 8, a fastener element 412 is attached to one end edge of each fastener tape 410 by pulp injection molding, while a main body of the bag 400 is formed on the surface portion from the vicinity of the center of each fastener tape 410 to the other end edge. 406 is connected by gluing. The gluing area is preferably wide from the viewpoint of securing the adhesive force between the main body 406 of the bag 400 and the fastener tape 410. Therefore, in this embodiment, the fastener tape 410 is wide.
- the fastener tape of a slide fastener usually used for clothes or the like is about 20 mm, while the wide fastener tape 410 is preferably 1.5 to 2 times, that is, 30 to 40 mm.
- a dotted line 408 indicates the slider with a virtual line.
- the slide fastener and snap fastener described above can be used not only for bags but also for clothes.

Abstract
Description
図1には、本発明の第一の実施形態に係るスライドファスナー100の正面図が示されている。スライドファスナー100は、断面視膨大状の芯紐114を有する一対のファスナーテープ112、一対のファスナーエレメント108の列、引手取付部118を備えたスライダー104、引手102、上止具106、及び下止具110によって構成されている。ファスナーエレメント108の列は芯紐114上に射出成形される。本明細書では、スライダーがエレメント列を噛合させるように摺動する向きを上方とし、エレメント列を分離させるように摺動する向きを下方とする。なお、各ファスナーテープ112にファスナーエレメント108の列が取り付けられた状態のものをファスナーストリンガーと呼ぶ。また、各ファスナーストリンガーが対になったものをファスナーチェンと呼ぶ。また、上下方向に垂直でファスナーテープの面に水平な方向を幅方向とする。
また、同じファスナーテープで、ファスナーエレメントにセルロース繊維を70重量%、ポリオレフィン(ポリプロピレン)を30重量%含有する材料を使用した場合には、ファスナーストリンガー全体として、セルロース繊維が83重量%、ポリオレフィンが17重量%含有することになり、紙としてのリサイクル性が向上する。さらに、同じファスナーテープで、ファスナーエレメントにセルロース繊維が35重量%、ポリオレフィン(ポリプロピレン)が65重量%含有する材料を使用した場合には、ファスナーストリンガー全体として、セルロース繊維が64重量%、ポリオレフィンが36重量%含有することになり、紙としてリサイクル可能で、かつ強度のあるファスナーエレメントとできる。
図3には、本発明の第二の実施形態に係るスライドファスナー200の正面図が示されている。スライドファスナー200は一対のファスナーテープ212、そのファスナーテープ212の対向する端縁部に沿って取り付けられる一対のファスナーエレメント208の列、引手取付部218を備えたスライダー204、引手202、上止具206、及び下止具210によって構成されている。
図6には、本発明の第三の実施形態に係るスナップファスナー300の斜視図が示されている。スナップファスナー300は表裏一対のファスナーテープ306、及び各ファスナーテープ306に射出成形された係合素子であるスナップエレメント(雄部材304及び雌部材302)で構成される。雄部材304は、一方のファスナーテープ306上に設けられた円板状の基板304bと、基板304b上に突設され、基板304bよりも小さい直径をもつ同軸円筒状の首部304cと、首部304cの先端に設けられ、首部304cよりも大きい直径をもつ同軸円板状の係合頭部304aとを有する。雌部材302は、他方のファスナー306上に設けられた円板上の基板302cと、基板302cの外周に突設された壁302bと、基板302cの中心に穿設された係合孔部302aとを有する。係合頭部304aと係合孔部302aの嵌合及び脱離によって、スナップファスナーの開閉動作が行われる。
紙糸を使用したファスナーテープ306にスナップエレメント304、302を射出成形するには、射出成形用の上型と下型の間にファスナーテープ306を挟んで、その状態で材料を射出して、ファスナーテープ306の表裏面に射出成形すればよい。表裏面に成形されたスナップエレメント304、302は、織成又は編成の組織の間を通って表裏で連結される。また、紙をそのまま使用したファスナーテープ306にスナップエレメント304、302を射出成形技術にて成形する場合でも、射出成形用の上型と下型の間にファスナーテープ306を挟んで、その状態で材料を射出して、ファスナーテープ306の表裏面に射出成形すればよい。表裏面に成形されたスナップエレメントとの界面には、互いのセルロース繊維が絡み合っている。射出成形の場合には、その界面においてセルロース繊維同士が絡み合うことで、一体化しているので、スナップエレメント304、302はファスナーテープ306の表裏にわたって形成されている必要はない。そのため、ファスナーテープ306の表裏面のうち、スナップエレメント304、302が互いに対面する側のみにスナップエレメントを304、302形成することができ、その反対面側には形成されなくてもよい。
