下記特許文献１には、水平状態を維持して持ち運ぶことが望まれる、寿司等の食料或いは和菓子等の菓子を収納した折箱を収納するのに適した合成樹脂フィルム製手提袋として、扁平状態において、底壁、この底壁に重なるカバー壁、底壁の両側縁の各々をカバー壁の両側縁の各々に夫々接続する両側壁を含み、両側壁の各々は幅方向内側に横断面においてＷ字形状に折り込まれており、底壁、カバー壁及び両側壁の両端縁は溶着されている手提袋が開示されている。カバー壁を分離されている幅方向中心から夫々幅方向外方に変位せしめて折箱の如き物品を袋内に導入或いは導出するための入口を大きく開口するのを助長するために、底壁及びカバー壁の両端縁の各々の幅方向中央部に略矩形状の切欠を形成することも、当業者には周知である。 In Patent Document 1 below, a synthetic resin film carrier bag suitable for storing food such as sushi or confectionery such as Japanese confectionery, which is desired to be carried in a horizontal state, is described in a flat state. , a bottom wall, a cover wall overlapping the bottom wall, and side walls connecting each side edge of the bottom wall to each side edge of the cover wall, each of the side walls extending inward in the width direction in a W-shaped cross section. Disclosed is a carrier bag that is folded into a shape and the edges of the bottom wall, cover wall and both side walls are welded. A bottom wall and a cover are provided for displacing the cover walls widthwise outward from the widthwise center from which they are separated, thereby facilitating wide opening of the entrance for introducing or withdrawing articles such as folding boxes into or from the bag. It is also well known to those skilled in the art to form a generally rectangular notch in the widthwise center of each of the end edges of the wall.

特公平５－４９４５７号Japanese Patent Publication No. 5-49457

而して、従来の手提袋においては、上記切欠を形成することによって入口を大きく開口することを意図しているが、本発明者等の経験によれば、開口される入口の大きさが未だ充分ではなく、使い勝手を更に向上するためには入口を一層大きく開口することができるようにせしめることが望まれている。 Therefore, in the conventional carrier bag, the notch is formed so that the entrance can be opened widely. This is not sufficient, and in order to further improve usability, it is desired to make the entrance wider.

本発明は、上記事実に鑑みてなされたものであり、その主たる技術的課題は、手提袋全体の寸法を大きくする必要なくして且つ製造コストを増大せしめることなくして、従来の手提袋に比べて入口を一層大きく開口することができる、新規且つ改良された合成樹脂フィルム製手提袋を提供することである。 The present invention has been made in view of the above-mentioned facts, and its main technical problem is to eliminate the need to increase the size of the entire carrier bag and increase the manufacturing cost, compared to conventional carrier bags. To provide a new and improved synthetic resin film carrier bag capable of opening the entrance wider.

本発明者等は、鋭意検討の結果、驚くべきことに底壁及びカバー壁の両端縁の各々の幅方向中央部に形成する切欠を独特な形状にすることによって上記主たる技術的課題を達成することができることを見出した。 As a result of intensive studies, the present inventors surprisingly achieved the above-mentioned main technical object by making the cutouts formed in the central portions in the width direction of each of the both end edges of the bottom wall and the cover wall unique shapes. I found that it can be done.

即ち、本発明によれば、上記主たる技術的課題を達成する合成樹脂フィルム製手提袋として、
扁平状態において、矩形状の底壁、該底壁に重なるカバー壁、該底壁の両側縁の各々を該カバー壁の両側縁の各々に夫々接続する両側壁を含み、該両側壁の各々は幅方向内側に横断面においてＷ字形状に折り込まれており、該底壁、該カバー壁及び該両側壁の両端縁は溶着されており、該カバー壁は幅方向中心において長手方向全体に渡って分離されており、該底壁及び該カバー壁の両端縁の各々の幅方向中央部には切欠が形成されている、合成樹脂フィルム製手提袋において、
該切欠の各々は、幅方向に間隔をおいて該両端縁の各々から長手方向内側に延びる一対の側縁と該両端縁に対して長手方向内側に間隔をおいて幅方向に延びる底縁と、該側縁の各々を該底縁の両端の各々の接続する一対の接続縁によって規定されており、該接続縁の各々は該側縁の各々の長手方向内側端から幅方向外側及び長手方向内側に向かって円弧状に延び、次いで幅方向内側及び長手方向内側に円弧状に延び、しかる後に幅方向内側及び長手方向外側に向かって該底縁の両端の各々まで円弧状に延びる、ことを特徴とする、合成樹脂フィルム製手提袋が提供される。 That is, according to the present invention, as a synthetic resin film carrier bag that achieves the above main technical problems,
In a flat state, it includes a rectangular bottom wall, a cover wall overlapping the bottom wall, and side walls connecting each side edge of the bottom wall to each side edge of the cover wall, each of the side walls The bottom wall, the cover wall, and both side walls are folded inward in the width direction in a W-shape in cross section, and both edges of the bottom wall, the cover wall, and the side walls are welded, and the cover wall extends along the entire longitudinal direction at the center in the width direction. A synthetic resin film carrier bag that is separated and has a notch formed in the center of the width direction of each of both end edges of the bottom wall and the cover wall,
Each of the notches has a pair of side edges extending longitudinally inwardly from each of the end edges and spaced apart in the width direction, and a bottom edge extending in the width direction spaced longitudinally inwardly of the end edges. , each of the side edges is defined by a pair of connecting edges connecting each of the ends of the bottom edge, each of the connecting edges extending laterally outward and longitudinally from the longitudinally inner end of each of the side edges. arcuately extending inwardly, then arcuately extending widthwise inward and longitudinally inward, and then arcuately extending widthwise inward and longitudinally outward to each of the ends of the bottom edge; A synthetic resin film carrier is provided.

好ましくは、 該カバー壁の幅方向中心において分離されている分離縁には、該カバー壁の上面上を幅方向外側に延び次いで幅方向内側に延びる横断面においてＶ字形状の付加壁が接続されている。該カバー壁及び該付加壁には、幅方向中央部且つ長手方向中央部を長手方向に細長く延在する開口が規定されており、該付加壁の各々は該開口の長手方向両側において、幅方向外側に向かって長手方向外側に傾斜して延びる溶着ラインに沿って該カバー壁の上面に溶着されているのが好都合である。 Preferably, the separation edge separated at the widthwise center of the cover wall is connected to an additional wall having a V-shaped cross section extending widthwise outward and then widthwise inward on the upper surface of the cover wall. ing. The cover wall and the additional wall define an opening extending longitudinally at the widthwise central portion and the longitudinally central portion, each of the additional walls extending in the widthwise direction on both sides of the opening in the longitudinal direction. It is expediently welded to the upper surface of the cover wall along a weld line extending longitudinally outwardly obliquely towards the outside.

本発明の合成樹脂フィルム製手提袋においては、底壁及びカバー壁の両端縁の各々の幅方向中央部に形成する切欠が独特な形状にせしめられている故に、手提袋全体の寸法を大きくする必要なくして且つ製造コストを増大せしめることなくして、従来の手提袋に比べて入口を一層大きく開口することができる。 In the synthetic resin film carrier of the present invention, the cutouts formed in the center of the width direction of each of the both ends of the bottom wall and the cover wall have a unique shape, so that the overall size of the carrier is increased. The entrance can be opened wider than conventional handbags without the need and increased manufacturing costs.

以下、添付図面を参照して更に詳細に説明する。 Further details will be described below with reference to the accompanying drawings.

図１及び図２（図２においては、図面の上下方向における壁の重なりを誇張して図示している）には、本発明に従って構成された合成樹脂フィルム製手提袋の好適実施形態が図示されている。全体を番号２で示す手提袋は、底壁４、この底壁４に重なる全体として略矩形状のカバー壁６及び両側壁８を含んでいる。図示の手提袋２は、更に、カバー壁６に接続された付加壁１０を含んでいる。かような手提袋２は、厚さが０．０２乃至０．０８ｍｍ程度のポリエチレンフィルムの如く適宜の合成樹脂製フィルムから形成されているチューブ状合成樹脂製フィルム素材に、それ自体は周知の折り畳み加工、切断加工及び溶着加工を施すことによって好都合に製造することができる。 FIGS. 1 and 2 (in FIG. 2, the overlap of the walls in the vertical direction of the drawing is exaggerated) show a preferred embodiment of a synthetic resin film carrier constructed according to the present invention. ing. A handbag generally indicated by numeral 2 includes a bottom wall 4 , a generally rectangular cover wall 6 overlapping the bottom wall 4 and side walls 8 . The illustrated glove 2 further includes an additional wall 10 connected to the cover wall 6 . Such a carrier bag 2 is made of a synthetic resin film material such as a polyethylene film having a thickness of about 0.02 to 0.08 mm. It can be manufactured conveniently by processing, cutting and welding.

底壁４は矩形状であり、この底壁４に重なるカバー壁６も後述する開口を除いて矩形状である。底壁４の両側縁の各々をカバー壁６の両側縁の各々に夫々接続している両側壁８の各々は、図２を参照することによって理解される如く、扁平状態（即ち底壁、両側壁８、カバー壁４及び付加壁１０を密に重ね合わした状態）においては幅方向（図１において左右方向）内側に折り込まれており、横断面においてＷ字形状である。カバー壁６並びに付加壁１０はチューブ状合成樹脂フィルム素材を長手方向（図１において上下方向）全体に渡って切断することによって、幅方向中心において分離されている。付加壁１０の各々は、カバー壁６の分離されている幅方向に位置する分離縁に続いて、カバー壁６の上面を幅方向外側に延び次いで幅方向内側に延び、横断面においてＶ字形状である。図１を参照することによって理解されるとおり、底壁４、両側壁８、カバー壁６及び付加壁１０は、両端縁（図１において上端縁及び下端縁）に沿って相合に溶着されている。図１においては、便宜上多数の点を施すことによって溶着部１２を示している。 The bottom wall 4 is rectangular, and the cover wall 6 overlapping the bottom wall 4 is also rectangular except for an opening which will be described later. Each of the side walls 8 connecting each of the side edges of the bottom wall 4 to each of the side edges of the cover wall 6, respectively, is in a flattened state (i.e., bottom wall, both sides), as will be appreciated by referring to FIG. When the wall 8, the cover wall 4, and the additional wall 10 are closely overlapped, they are folded inward in the width direction (horizontal direction in FIG. 1) and have a W shape in cross section. The cover wall 6 and the additional wall 10 are separated at the center in the width direction by cutting the tubular synthetic resin film material along the entire longitudinal direction (vertical direction in FIG. 1). Each of the additional walls 10 extends widthwise outward and then widthwise inward on the upper surface of the cover wall 6 following the separation edge located in the width direction where the cover wall 6 is separated, and has a V-shaped cross section. is. 1, the bottom wall 4, side walls 8, cover wall 6 and additional wall 10 are welded together along their opposite edges (top and bottom edges in FIG. 1). . In FIG. 1, the welded portion 12 is indicated by a number of dots for convenience.

図１及び図２を参照して説明を続けると、カバー壁６及び付加壁１０には、幅方向中央部及び長手方向中央部を長手方向に細長く延びる開口１４が規定されている。かかる開口１４はチューブ状合成樹脂フィルム素材の所要部位を切り取ることによって形成することができる。従って、開口１４が形成されている領域においては、付加壁１０はカバー壁６から分離されている。付加壁１０の各々は、開口１４の長手方向両側において、幅方向外側に向かって長手方向外側に傾斜して延びる溶着ライン１６に沿ってカバー壁６に溶着されている。図１においては、便宜上多数の点を施すことによって溶着ライン１６を示している。 Continuing with the description with reference to FIGS. 1 and 2, the cover wall 6 and the additional wall 10 are defined with an opening 14 elongated in the width direction central portion and the longitudinal direction central portion in the longitudinal direction. Such an opening 14 can be formed by cutting a desired portion of the tubular synthetic resin film material. The additional wall 10 is thus separated from the cover wall 6 in the region where the opening 14 is formed. Each of the additional walls 10 is welded to the cover wall 6 on both longitudinal sides of the opening 14 along welding lines 16 that extend outward in the width direction and are inclined longitudinally outward. In FIG. 1, weld lines 16 are indicated by multiple dots for convenience.

底壁４、カバー壁６及び付加壁１０の両端縁の各々の幅方向中央部には切欠１８が形成されている。従来の手提袋においては切欠は略矩形状であったが、本発明に従って構成された手提袋２においては切欠１８は以下に説明するとおりの独特な形状であることが重要である。図１に明確に図示するとおり、切欠１８の各々は、幅方向に間隔をおいて両端縁の各々から長手方向内側に延びる一対の側縁２０と両端縁に対して長手方向内側に間隔をおいて幅方向に、好ましくは両端縁の各々に対して平行に、延びる底縁２２と、側縁２０の各々を底縁２２の両端の各々の接続する一対の接続縁２４によって規定されている。そして、接続縁２４の各々は、側縁２０の長手方向内側端の各々から幅方向外側及び長手方向内側に向かって円弧状に延びる第一の部分２４－１、第一の部分２４－１に続いて幅方向内側及び長手方向内側に円弧状に延びる第二の部分２４－２、及び第二の部分２４－２に続いて幅方向内側及び長手方向外側に向かって底縁２２の両端の各々まで円弧状に延びる第三の部分２４－３から構成されている。 A notch 18 is formed in each widthwise central portion of both end edges of the bottom wall 4 , the cover wall 6 and the additional wall 10 . It is important to note that, whereas in conventional tote bags, the notch is generally rectangular in shape, in tote bag 2 constructed in accordance with the present invention, notch 18 has a unique shape as described below. As best shown in FIG. 1, each of the notches 18 is spaced longitudinally inwardly with respect to a pair of laterally spaced side edges 20 extending longitudinally inwardly from each of the opposite edges. It is defined by a bottom edge 22 extending widthwise, preferably parallel to each of the end edges, and a pair of connecting edges 24 connecting each of the side edges 20 to each of the ends of the bottom edge 22 . Each of the connecting edges 24 has a first portion 24-1 extending in an arc from each of the longitudinally inner ends of the side edges 20 toward the widthwise outer side and the longitudinally inner side. A second portion 24-2 extending inwardly in the widthwise direction and inwardly in the longitudinal direction in an arc, and each end of the bottom edge 22 following the second portion 24-2 and extending inwardly in the widthwise direction and outwardly in the longitudinal direction. It is composed of a third portion 24-3 that extends arcuately to the .

上述した手提袋２内に箱折の如き物品を導入する或いは手提袋２内から物品を導出する際には、付加壁１０における上記溶着ライン１６間に位置する長手方向中央部分を把持して付加壁１０と共に幅方向中心において分離されているカバー壁６の両側部を相互に離隔する方向に変位せしめて入口２６を生成する。然るに、本発明に従って構成された手提袋２においては、切欠１８が上述したとおりの独特な形状である故に、切欠１８が形成されている部位が図３に図示する形状に変形されて幅方向にも充分に大きい入口２６が生成される。箱折の如き物品が収納された手提袋２は、付加壁１０における上記溶着ライン１６間に位置する長手方向中央部分を把持して手提げることができる。これに対して、切欠１１８が略矩形状である従来の手提袋１０２においては、切欠１１８が形成されている部位が図４に図示する形状に変形され、生成される入口１２６の幅方向寸法が比較的小さい値に制限され、充分に大きな入口１２６を生成することができない。 When an article such as a box-folded article is introduced into the above-mentioned carrier bag 2 or when an article is taken out from the carrier bag 2, the longitudinal central portion of the additional wall 10 located between the welding lines 16 is gripped and attached. The sides of the cover wall 6, which are separated at the widthwise center with the wall 10, are displaced away from each other to create the inlet 26. As shown in FIG. However, in the carrier bag 2 constructed according to the present invention, since the notch 18 has the unique shape as described above, the portion where the notch 18 is formed is deformed into the shape shown in FIG. A sufficiently large inlet 26 is created. The carrier bag 2 containing an article such as a folded box can be carried by gripping the longitudinal central portion of the additional wall 10 located between the welding lines 16 . On the other hand, in the conventional carrier bag 102 in which the notch 118 is substantially rectangular, the portion where the notch 118 is formed is deformed into the shape shown in FIG. It is limited to relatively small values and cannot produce a sufficiently large inlet 126 .

以上、図１乃至図３を参照して本発明に従って構成された手提袋の好適実施形態について詳細に説明したが、本発明はかかる実施形態に限定されるものではなく、本発明の範囲を逸脱することなく種々の変形乃至修正が可能であることは多言を要しない。例えば、図示の実施形態においては、カバー壁６に接続された付加壁１０を付設しているが、付加壁１０を省略することもできる。この場合には、周知の如く、別個に形成した２個の帯状片をカバー壁６の幅方向中央部且つ長手方向中央部においてカバー壁６に積層し、２個の帯状片の長手方向両端部をカバー壁６に溶着して手提用把持部を形成することができる。 Although the preferred embodiment of the carrier constructed in accordance with the present invention has been described in detail above with reference to FIGS. It goes without saying that various modifications and modifications can be made without modification. For example, in the illustrated embodiment, an additional wall 10 connected to the cover wall 6 is attached, but the additional wall 10 may be omitted. In this case, as is well known, two separately formed strips are laminated on the cover wall 6 at the central portion in the width direction and the central portion in the longitudinal direction of the cover wall 6, and the two strips are laminated at both ends in the longitudinal direction of the cover wall 6. can be welded to the cover wall 6 to form a hand grip.
