なお、以下に説明する実施形態はあくまで一例であり、本考案の要旨を逸脱しない範囲で当業者が行う種々の設計的改良も本考案の範囲に含まれる。 The embodiment described below is merely an example, and various design improvements made by those skilled in the art without departing from the gist of the present invention are also included in the scope of the present invention.

（第１実施形態）
図１には本考案の内袋体の全体斜視図を示す。内袋体は袋体１を備えており、袋体１は再生ポリエチレンや再生ポリプロピレン、再生塩化ビニル等を円筒状シートに成形した後、その一端１１（図１では下端）開口を溶着で閉じて、他方（図１では上方）へ開放する開放口１２を有する袋状としたものである。 (First embodiment)
FIG. 1 shows an overall perspective view of the inner bag body of the present invention. The inner bag body is provided with a bag body 1. The bag body 1 is formed by molding recycled polyethylene, recycled polypropylene, recycled vinyl chloride or the like into a cylindrical sheet, and then closing one end 11 (lower end in FIG. 1) by welding. The bag has an opening 12 that opens to the other side (upward in FIG. 1).

袋体１の開放口１２の外周縁には全周に一定間隔をおいて複数の保持部材２が装着されている。これら保持部材２の袋体１への装着は、以下に詳細を説明する保持部材２の一方の側縁２１を、袋体１の外表面に熱融着することによって行われる。 A plurality of holding members 2 are mounted on the outer peripheral edge of the opening 12 of the bag body 1 at regular intervals around the entire circumference. The holding member 2 is attached to the bag body 1 by heat-sealing one side edge 21 of the holding member 2, which will be described in detail below, to the outer surface of the bag body 1.

保持部材２の詳細を図２に示す。保持部材２は樹脂材よりなり、一定長さの基体２１を有している。基体２１は、押し出し成形等によって成形された帯状体を必要長さに切断するか、あるいは射出成形等によって予め所定の長さで成形される。上記保持部材２を構成する合成樹脂材は、再生ポリエチレンや再生ポリプロピレン、再生塩化ビニル等を適宜使用することができる。 Details of the holding member 2 are shown in FIG. The holding member 2 is made of a resin material and has a base 21 having a certain length. The base body 21 is formed by cutting a strip-like body formed by extrusion molding or the like into a required length, or by a predetermined length in advance by injection molding or the like. As the synthetic resin material constituting the holding member 2, recycled polyethylene, recycled polypropylene, recycled vinyl chloride, or the like can be used as appropriate.

保持部材２の基体２１には図２に示すように、一方の側縁２２の端縁に沿って傘状断面に突出する嵌合凸部２４が形成され、他方の側縁２３の端縁にはこれに沿って略逆Ｕ字断面の嵌合凹部２５が形成されている。また、基体２１の中央部２６は薄肉としてある。このような保持部材２は、図２に示す展開状態で中央部２６が略水平に延びるような姿勢で、図３の鎖線で示すように、嵌合凸部２４を形成した側縁２２が下方に位置するようにして当該側縁２２の、嵌合凸部２４が形成されていない裏面が、袋体１の開放口１２外周縁の外表面に熱融着によって固定し装着されている。 As shown in FIG. 2, the base 21 of the holding member 2 is formed with a fitting convex portion 24 protruding in an umbrella-like cross section along the edge of one side edge 22, and on the edge of the other side edge 23. A fitting concave part 25 having a substantially inverted U-shaped cross section is formed along this. The central portion 26 of the base 21 is thin. Such a holding member 2 has a posture in which the central portion 26 extends substantially horizontally in the unfolded state shown in FIG. 2, and the side edge 22 on which the fitting convex portion 24 is formed is downward as shown by a chain line in FIG. The back surface of the side edge 22 on which the fitting convex portion 24 is not formed is fixed and attached to the outer surface of the outer peripheral edge of the opening 12 of the bag body 1 by heat fusion.

この状態で、袋体１の開放口１２の周長よりも長い一本の紐材３を用意して、紐材の中間部を、各保持部材２の外方へ向く中央部２６に沿って位置させ、各保持部材２の側縁２３を薄肉の中央部２６を境に下方へ折り曲げて（鎖線で示す状態から実線で示す状態）嵌合凸部２４を嵌合凹部２５内に進入させる。この時、中央部２６に沿って位置させられた紐材３は両側縁２２，２３間に位置させられて、これらの間に形成された扁平な筒状空間Ｓ内に挿通された状態となる。そして紐材３の両端部３１，３２は図１に示すように、隣り合う保持部材２の対向する端面から外方へ引き出される。 In this state, a single string member 3 longer than the circumferential length of the opening 12 of the bag body 1 is prepared, and an intermediate portion of the string member is arranged along a central portion 26 facing outward of each holding member 2. Then, the side edge 23 of each holding member 2 is bent downward with the thin central portion 26 as a boundary (from the state indicated by the chain line to the state indicated by the solid line), and the fitting convex portion 24 enters the fitting concave portion 25. At this time, the string member 3 positioned along the central portion 26 is positioned between the side edges 22 and 23 and is inserted into the flat cylindrical space S formed therebetween. . As shown in FIG. 1, both end portions 31 and 32 of the cord material 3 are drawn outward from the opposing end surfaces of the adjacent holding members 2.

袋体１の開放口１２を閉じる場合には、紐材３の両端部３１，３２を引いて袋体１の開放口１２を絞る。紐材３の両端部３１，３２は十分に開放口１２を絞った状態で互いに結ばれる。 When closing the opening 12 of the bag body 1, the both ends 31 and 32 of the string member 3 are pulled to narrow the opening 12 of the bag 1. Both end portions 31 and 32 of the cord material 3 are connected to each other with the opening 12 sufficiently narrowed.

なお、紐材３の両端部３１，３２を結ぶのに代えて、図４に示すように、保持部材２を利用して、両端部３１，３２を保持部材２の中央部２６に互いに反対方向から位置させ、嵌合凸部２４（図３参照）と嵌合凹部２５を嵌合させて紐材３の両端部３１，２３２を両側縁２２，２３で挟持固定するようにしても良い。 Instead of tying both end portions 31 and 32 of the cord material 3, as shown in FIG. 4, the holding member 2 is used to connect the both end portions 31 and 32 to the central portion 26 of the holding member 2 in opposite directions. The both ends 31 and 232 of the cord material 3 may be sandwiched and fixed between the side edges 22 and 23 by fitting the fitting convex part 24 (see FIG. 3) and the fitting concave part 25 together.

（第２実施形態）
図５には本考案の他の実施形態を示す。本実施形態では各保持部材２は下方に位置させたその嵌合凸部２４と嵌合凹部２５を嵌合させることによって袋体１の開放口１２の周縁に装着されている。紐材３は開放口１２の周縁の上方に位置する各保持部材２の両側縁２２，２３間に挿通されている。そして、紐材３の両端部３１，３２は隣り合う保持部材２の対向する端面から外方へ引き出されている。 (Second Embodiment)
FIG. 5 shows another embodiment of the present invention. In this embodiment, each holding member 2 is attached to the periphery of the opening 12 of the bag body 1 by fitting the fitting convex portion 24 and the fitting concave portion 25 positioned below. The string member 3 is inserted between both side edges 22 and 23 of each holding member 2 located above the periphery of the opening 12. Then, both end portions 31 and 32 of the string member 3 are drawn outward from the opposing end surfaces of the adjacent holding members 2.

このような構造は以下の手順によって実現される。すなわち、保持部材２の基体２１を展開させた状態で嵌合凹部２５を形成した側縁２３を下方に位置させ、薄肉の中央部２６に沿って紐材３の中間部分を略水平に位置させておく。この状態で中央部２６を境に、嵌合凸部２４を形成した側縁２２を下方に折り曲げて嵌合凸部２４を嵌合凹部２５内に進入させてこれらを嵌合させる（図６）。この際、袋体１の開放口１２の周縁が嵌合凸部２４と嵌合凹部２５の間で深く屈曲させられて挟まれ、このようにして袋体１の開放口１２の周縁に保持部材２が装着される。同時に両側縁２２，２３間に形成された扁平な筒状空間Ｓ内に紐材３が挿通された状態で保持される。 Such a structure is realized by the following procedure. That is, the side edge 23 in which the fitting recess 25 is formed in a state where the base 21 of the holding member 2 is unfolded is positioned downward, and the middle portion of the string member 3 is positioned substantially horizontally along the thin central portion 26. Keep it. In this state, the side edge 22 on which the fitting convex portion 24 is formed is bent downward with the central portion 26 as a boundary, and the fitting convex portion 24 enters the fitting concave portion 25 to fit them (FIG. 6). . At this time, the peripheral edge of the opening 12 of the bag body 1 is deeply bent between the fitting convex part 24 and the fitting concave part 25, and is thus held on the peripheral edge of the opening part 12 of the bag body 1. 2 is installed. At the same time, the string material 3 is held in a flat cylindrical space S formed between the side edges 22 and 23.

本実施形態によっても第１実施形態と同様の作用効果が得られるとともに、保持部材２を袋体１に熱融着する手間が省略できる。 According to the present embodiment, the same effect as that of the first embodiment can be obtained, and the trouble of heat-sealing the holding member 2 to the bag body 1 can be omitted.
