Description

本考案は食品その他の小物商品を収容するためのネット袋に関する。 The present invention relates to a net bag for storing food and other small goods.

従来、多数のモノフィラメント状の線条を交差して一体化した伸縮自在な網目を構成してなるネット袋がある（例えば、特許文献１参照。）。
然し乍、このようなネット袋の致命的な問題点は、内部に収容する商品の名称等に関する表示、バーコード表示、原材料マーク表示、原産地表示等の各種表示を施す場合、当該袋は網状であるために、このような表示を直接印刷することが不可能とされる点にあった。 2. Description of the Related Art Conventionally, there is a net bag formed of a stretchable mesh formed by crossing and integrating a large number of monofilament-like filaments (see, for example, Patent Document 1).
However, the fatal problem with such net bags is that when the display is related to the names of goods contained in the interior, bar code display, raw material mark display, place of origin display, etc., the bag is reticulated. For this reason, it is impossible to directly print such a display.

このような問題を解消したネット袋として、本考案と同一の発明者・出願人とする実用新案登録出願に係る「ネット袋」がある（特許文献２参照。）。これは、ネット袋主体に対して、当該ネット袋主体内に収容する商品に関する各種表示の印刷を表面に施してなる合成樹脂製フイルム状シート材で形成した表示用シートを熱溶着するように構成したものである。そして、当該表示用シートはネット袋主体を表面全体に形成するように構成する場合も有る。 As a net bag that solves such a problem, there is a “net bag” related to a utility model registration application that is the same inventor and applicant as the present invention (see Patent Document 2). This is configured to heat weld a display sheet formed of a synthetic resin film-like sheet material, which is printed on the surface with various displays relating to products contained in the net bag main body. It is a thing. And the said display sheet may be comprised so that a net bag main body may be formed in the whole surface.

然し乍、このように単なる矩形状の袋であると、商品の収容量が限られ、これを解消する手段としては、本考案と同一の発明者・出願人とする特許出願に係る「ネット袋」のように、側部に内側に折り込んだマチ部を形成し、商品の収容時に当該マチ部分が開いて収容能力の増大化を図るように構成したものがある（特許文献３参照。）。また、このように側部にマチを形成した袋としては紙袋等に多く見られる手段である。 However, if the bag is simply a rectangular bag as described above, the capacity of the product is limited, and as means for solving this, the “net bag” according to the patent application of the same inventor / applicant as the present invention can be used. As shown in FIG. 3, there is a structure in which a gusset portion folded inward is formed on the side portion, and the gusset portion is opened at the time of storing a product to increase the storage capacity (see Patent Document 3). Moreover, as a bag having a gusset on the side as described above, it is a means often found in a paper bag or the like.

そして、上述した特許文献３に示す「ネット袋」は、ネット部分には印刷表示を行うことが出来ないため、ネット材で形成されかつ両側部にマチ部具えた袋の表裏両面に表示用シートを別に重ねて設けるように構成してある。 And since the "net bag" shown in the above-mentioned patent document 3 cannot be printed on the net part, the display sheet is formed on both the front and back sides of the bag formed of the net material and having gussets on both sides. Are provided so as to overlap each other.

すなわち、ネット袋の場合は、側部に形成するマチ部の有無を問わず、商品の商標、品質説明、バーコード表示等を行うための印刷面の形成には、ネット状の素材は印刷には不適当であるから、必然、当該袋に対して印刷表示のための表示用シートを重合させて設ける必要があった。 In other words, in the case of a net bag, the net-like material is used for printing to form a printing surface for displaying the trademark, quality explanation, barcode display, etc. of the product regardless of the presence or absence of a gusset on the side. Therefore, it was necessary to polymerize a display sheet for print display on the bag.

ところで、ネット袋を形成する素材たるネット材は比較的高価であり、特に、延伸したフイルムから製造した割繊網状体を縦・横方向に配列した特殊不織布である「ワリフ（登録商標）」をネット材として用いた場合、高価性が著しいものとされる。 By the way, the net material, which is the material forming the net bag, is relatively expensive. In particular, “Warif (registered trademark)”, which is a special nonwoven fabric in which split fiber nets manufactured from stretched films are arranged in the vertical and horizontal directions, is used. When used as a net material, the cost is considered to be remarkable.

更に、側部に形成するマチ部であるが、紙材等と異なりネット材は弾力性があるため、商品を詰めることに依って当該マチ部が外方に開いた場合、折り目のついた整然たる膨らみとはならず、不規則に膨らんだ形状となってしまうため、袋詰め商品としての見場（ミバ）が悪くなってしまった。本考案はこのような問題点を解消した新規のネット袋の提供を図ったものである。 Furthermore, it is a gusset part that is formed on the side, but unlike paper materials, the net material is elastic, so if the gusset part opens outward by packing products, it will be creased and orderly Since it does not bulge but becomes an irregularly bulging shape, the view as a bag-packed product (Miva) has deteriorated. The present invention is intended to provide a new net bag that solves such problems.

The folding parts 1a, 1a and 2a, 2a are formed, and folding gusset members 3 and 4 formed of a net material are interposed between the front-forming film sheet material 1 and the back-forming film sheet material 2. At the same time, the both side edge portions are joined and connected based on the thermal welding P in a state where they are overlapped with the connecting folding portions 1a, 1a and 2a, 2a, and further, the front-form film sheet 1 and the back surface are formed. Since the upper portion of the film-like sheet material 2 is configured so as to form the closed portion A based on heat welding together with the interleaved gusset members 3 and 4, the manufacturing cost is significantly reduced. , At the time of goods accommodation Expansion of kicking gusseted portion is extremely orderly shape retention.

何故ならば、本考案に係るネット袋は、比較的高価素材であるネット材を、マチ部のみに使用し、正面部及び背面部は比較的廉価なフイルム状シート材で形成するように構成したから、その製造コストを下げることができる。
同時に、上記折込マチ部材３及び４を、当該正面形成用フイルム状シート材１と背面形成用フイルム状シート材２の間に介在させると共に、その両側縁部分を、上記連結用折込部1ａ，1ａ及び2ａ，2ａと重合させた状態で熱溶着Ｐに基づき接合連結するように構成したから、当該溶着Ｐに基づく固化作用、及び連結用折込部1ａ，1ａ及び2ａ，2ａの重合的存在に基づき、ネット袋の両側部は一種の強度補修的作用が奏され、従って、本考案に係る袋内に所要商品を収容してマチ部材３及び４が開いた状態であっても、当該両側部は直線状を保持することとなり、袋詰め商品形態の整然性が保たれる。
そして、当該熱溶着Ｐ部分の存在は、ネット袋の強度的向上性にも貢献することとなる。 This is because the net bag according to the present invention is configured such that the net material, which is a relatively expensive material, is used only for the gusset portion, and the front and back portions are formed of a relatively inexpensive film-like sheet material. Therefore, the manufacturing cost can be reduced.
At the same time, the folding gusset members 3 and 4 are interposed between the front-forming film-like sheet material 1 and the back-forming film-like sheet material 2, and both side edge portions thereof are connected to the connecting folding parts 1a, 1a. And 2a, 2a in a polymerized state based on the thermal welding P, based on the solidification action based on the welding P and the polymerization presence of the connecting folding portions 1a, 1a and 2a, 2a. The both sides of the net bag have a kind of strength repairing action. Therefore, even if the gusset members 3 and 4 are opened in the bag according to the present invention with the necessary goods contained therein, The straight line shape is maintained, and the orderliness of the packaged product form is maintained.
And presence of the said heat welding P part will also contribute to the strength improvement property of a net bag.

本考案は請求項２に記載のような構成、すなわち、熱溶着可能とする材料製の正面形成用フイルム状シート材１と背面形成用フイルム状シート材２との両側部全長に亘って、連結用折込部1ａ，1ａ及び2ａ，2ａを形成すると共に、延伸したフイルムから製造した割繊網状体を縦・横方向に配列した特殊不織布であるワリフ（登録商標）を用いたネット材で形成した折込マチ部材３及び４を、上記正面形成用フイルム状シート材１と背面形成用フイルム状シート材２の間に介在させると共に、その両側縁部分を、上記連結用折込部1ａ，1ａ及び2ａ，2ａと重合させた状態で熱溶着Ｐに基づき接合連結し、更に、上記正面形成用フイルム状シート材１と背面形成用フイルム状シート材２の上方部分は、介在されている折込マチ部材３及び４と一括して熱溶着に基づく閉塞部Ａを形成するように構成したから、上記した請求項１の記載されたものと同様の作用効果を奏することとなる。 The present invention has a structure as described in claim 2, that is, it is connected over the entire length of both sides of the front-form film sheet material 1 and the back-form film sheet material 2 made of heat-weldable material. In addition to forming the folding parts 1a, 1a and 2a, 2a for use, it was formed of a net material using Warif (registered trademark), which is a special nonwoven fabric in which split fiber nets manufactured from stretched films are arranged in the vertical and horizontal directions. Folding gusset members 3 and 4 are interposed between the front forming film sheet material 1 and the back forming film sheet material 2, and both side edge portions thereof are connected to the connecting folding parts 1 a, 1 a and 2 a, 2a is joined and connected based on thermal welding P, and the upper portions of the front-form film-form sheet material 1 and the back-form film-form sheet material 2 are interleaved gusset members 3 and 4 together Because it was configured to form a closed section A based on the heat welding, and thus the same effects as those described in claim 1 described above.

同時に、折込マチ部材３及び４を、延伸したフイルムから製造した割繊網状体を縦・横方向に配列した特殊不織布であるワリフ（登録商標）を用いたネット材で形成するように構成したことにより、網目部分において高い通気性と優れた強度を奏することとなる。そして、そのメッシュ構造に基づき「薄くて軽量、通気性が良い」、「縦・横ともに高強度でバランスがよく、腰が強い」、「目ズレがなく定形性に優れている」、「他素材との組合せなど加工性に優れている」、「滞水、耐薬品性に優れている」と言うような特性が発揮されることとなる。 At the same time, the folding gusset members 3 and 4 are configured to be formed of a net material using Warif (registered trademark), which is a special nonwoven fabric in which split fiber nets manufactured from stretched films are arranged in the vertical and horizontal directions. As a result, high air permeability and excellent strength are exhibited in the mesh portion. And based on its mesh structure, it is “thin, lightweight, and has good ventilation”, “strength in both length and width, well-balanced, strong waist”, “excellent shape and excellent shapeability”, “others” The characteristics such as “excellent processability such as combination with materials” and “excellent water retention and chemical resistance” will be exhibited.

本考案は請求項３に記載のような構成、すなわち、熱溶着可能とする材料製の正面形成用フイルム状シート材１と背面形成用フイルム状シート材２の両方または何れか一方に、内部に収容する商品に関する商品名表示、バーコード表示、原材料マーク表示、原産地表示等の各種表示、並びに装飾的模様表示・地色的色彩表示等を成すための印刷を施すように構成したから、当該表示のための印刷が極めて鮮明に施され、商品購入者に対する詳細なる商品説明を施すことが可能化される。 The present invention has a configuration as claimed in claim 3, that is, a front-form film-form sheet material 1 and / or a back-form film-form sheet material 2 made of a material that can be heat-welded. The product name display, bar code display, raw material mark display, place of origin display, etc. related to the products to be stored, as well as printing to make decorative pattern display, ground color display, etc. Is printed very clearly, making it possible to give detailed product descriptions to product buyers.

本考案は請求項４に記載のような構成、すなわち、溶着可能とする材料製の正面形成用フイルム状シート材１と背面形成用フイルム状シート材２の両方または何れか一方を、透明または半透明のフイルム状シート材で形成することにより、購入者に対して、収容商品の可視的確認が果され、自分の目で見た上での納得のいく商品購入が果される。 The present invention has the structure as described in claim 4, that is, the front-form film-form sheet material 1 and / or the back-form film-form sheet material 2 made of a material that can be welded are transparent or semi-transparent. By forming it with a transparent film-like sheet material, the purchaser can be visually confirmed of the accommodated product, and the product can be purchased with his / her own eyes.

本考案は請求項５に記載のような構成、すなわち、熱溶着に基づく閉塞部Ａを縦方向にやや幅広く形成すると共に、当該閉塞部Ａの所要箇所に、商品の引掛け的展示または携行用持ち手として機能させるための吊り下用孔ａを設けるように構成したから、当該吊り下用穴ａ部分は、閉塞部Ａは正面形成用フイルム状シート材１と背面形成用フイルム状シート材２並びに折込マチ部材３または４の三者の熱溶着に基づく重合部分に穿設されるため、強度的に極めて強靭なものとされ、その穴縁に亀裂が生じるような恐れがない。 The present invention is configured as described in claim 5, that is, a closed portion A based on heat welding is formed slightly wider in the vertical direction, and a product is displayed at a required location of the closed portion A for use in a hook-up display or carrying Since the suspension hole a for functioning as a handle is provided, the suspension hole A includes the front-forming film-like sheet material 1 and the back-forming film-like sheet material 2. In addition, since the overlapped gusset member 3 or 4 is formed in the overlapped portion based on the heat welding of the three members, it is extremely strong in strength, and there is no fear that the hole edge will crack.

図に於いて、１は袋の正面形成用フイルム状シート材、２は同上背面形成用フイルム状シート材であって、夫々熱溶着可能とする合成樹脂性のフイルム状シート材で形成してある。そして、図面に於いては省略してあるが、当該フイルム状シート材の両者または何れか一方には、内部に収容する商品に関する商品名表示、バーコード表示、原材料マーク表示、原産地表示等の各種表示、並びに装飾的模様表示・地色的色彩表示等を成すための印刷が施されるように構成してある。 In the figure, 1 is a film sheet material for forming the front surface of the bag, and 2 is a film sheet material for forming the back surface of the bag, and is formed of a synthetic resin film sheet material that can be heat-welded. . Although omitted in the drawings, both or any one of the film-like sheet materials has various names such as a product name display, a bar code display, a raw material mark display, and a place of origin display regarding the products contained therein. Printing is performed for display, decorative pattern display, ground color display, and the like.

３及び４はネット材で形成した折込マチ部材であって、上記した正面形成用フイルム状シート材１と背面形成用フイルム状シート材２の両側部に内向きＶ字状に介在連設させることによって、マチ付きの袋を形成するためのものである。なお、当該折込マチ部材３，４の深さであるが、これは商品収容量に応じて適宜設定するものとする。 Reference numerals 3 and 4 denote folding gusset members formed of a net material, which are continuously provided in an inward V-shape on both sides of the front-form film sheet material 1 and the back-form film sheet material 2 described above. To form a gusseted bag. In addition, although it is the depth of the said folding gusset members 3 and 4, this shall be suitably set according to goods accommodation amount.

当該折込マチ部材３，４の上記介在連結手段であるが、これは前記正面形成用フイルム状シート材１及び背面形成用フイルム状シート材２の両側縁部分を全長に亘って内側に折り込むことによって、連結用折込部1ａ，1ａ及び2ａ，2ａを形成し、上記した折込マチ部材３及び４の両側縁部分を重ね合わせると共に、熱溶着Ｐに基づき接合連結するように構成してある。 The intervening connecting means of the folding gusset members 3 and 4 is formed by folding the side edge portions of the front forming film sheet material 1 and the back forming film sheet material 2 inward over the entire length. The connecting folding portions 1a, 1a and 2a, 2a are formed, and both side edge portions of the above-described folding gusset members 3 and 4 are overlapped and joined and connected based on the thermal welding P.

そして、このような連結状態においては、上記接合連結部分は熱溶着Ｐに基づく硬化作用と、連結用折込部1ａ，1ａ及び2ａ，2ａの形成に基づき整然たる折畳み形態が保持され、従って、袋内に所要の商品を詰め込んでマチ部材３,４が拡げられた状態にあっても、袋の側縁線は整然たる状態に保たれるように構成されているわけである。 And in such a connection state, the said joint connection part maintains the orderly folding form based on the hardening effect | action based on the heat welding P, and formation of the folding parts 1a, 1a and 2a, 2a for connection, Therefore, a bag Even if the gusset members 3 and 4 are in a state where the required products are packed therein and the gusset members 3 and 4 are expanded, the side edge lines of the bag are maintained in an orderly state.

すなわち、正面形成用フイルム状シート材１と背面形成用フイルム状シート材２は合成樹脂材料で形成されているため、柔軟的弾力性を備えたネット材と異なり、その連結用折込部1ａ，1ａ及び2ａ，2ａの形成は直線状に極めて確りとした折込み状態に保たれることとなる。 That is, since the front-form film sheet 1 and the back-form film sheet 2 are formed of a synthetic resin material, the connecting folding portions 1a and 1a are different from the net material having flexible elasticity. And the formation of 2a and 2a is kept in a folded state which is extremely straight and straight.

ところで、上述した折込マチ部材３，４の形成素材であるが、これは多数のモノフィラメント状の合成樹脂製線条を交差して一体化した伸縮自在な網目を有する網材を用いるものである。 By the way, although it is the formation material of the above-mentioned folding gusset members 3 and 4, this uses the net | network material which has the elastic network which crossed and integrated many monofilament-shaped synthetic resin filaments.

そして、当該折込マチ部材３，４の形成素材としては、上記したような単なる網材で形成する以外、延伸したフイルムから製造した割繊網状体を縦・横方向に配列した特殊不織布である「ワリフ（登録商標）」を用いることができる。すなわち、当該「ワリフ（登録商標）」とは、新日石プラスト社が商標を所有する商品であり、延伸したフイルムから製造した割繊網状体を縦・横方向に配列した特殊不織布で、メッシュ構造で高い通気性と強度を有している。そして、そのメッシュ構造に基づき「薄くて軽量、通気性が良い」、「縦・横ともに高強度でバランスがよく、腰が強い」、「目ズレがなく定形性に優れている」、「他素材との組合せなど加工性に優れている」、「滞水、耐薬品性に優れている」と言うような特性を備えた素材である。従って、このような「ワリフ」を用いることにより、袋として通気性、柔軟性を損なうことなく強靭性を具えたものとされる。本考案はこのようなワリフ（登録商標）を用いて実施する場合もある。 And as a forming material of the said folding gusset members 3 and 4, it is the special nonwoven fabric which arranged the split fiber net body manufactured from the stretched film in the vertical and horizontal direction other than forming with a simple net material as mentioned above. "Warif (registered trademark)" can be used. In other words, “Warif (registered trademark)” is a product owned by Nippon Oil Plastics Co., Ltd., a special non-woven fabric in which split fiber nets manufactured from stretched film are arranged in the vertical and horizontal directions. The structure has high breathability and strength. And based on its mesh structure, it is “thin, lightweight, and has good ventilation”, “strength in both length and width, well-balanced, strong waist”, “excellent shape and excellent shapeability”, “others” It is a material with characteristics such as “Excellent processability such as combination with materials” and “Excellent water retention and chemical resistance”. Therefore, by using such “warif”, the bag has toughness without impairing air permeability and flexibility. The present invention may be carried out using such a Warif (registered trademark).

上記したようにして、正面形成用フイルム状シート材１及び背面形成用フイルム状シート材２と折込マチ部材３，４とで形成されているネット袋は、その上縁部分は熱溶着に基づき一括して閉塞した閉塞部Ａを形成すると共に、その下端部分は開放させた状態が保たれており、この状態でネット袋素材としての販売に供されるものである。 As described above, the upper edge portion of the net bag formed of the front-forming film-like sheet material 1 and the back-forming film-like sheet material 2 and the folding gusset members 3 and 4 is collectively based on thermal welding. Thus, the closed portion A is formed, and the lower end portion thereof is kept open, and is provided for sale as a net bag material in this state.

そして、下縁側開口部に対する閉塞部処理は、ネット袋の購入者が所要の商品を収容した後に独自に施すものである。その閉塞する手段としては、当該部分を熱溶着に基づき閉塞する手段、または、ステイプラー（商標：ホッチキス）により閉塞する手段、或いは、紐により一括して束ねた結束形態に閉塞する手段が挙げられる。 And the closing part process with respect to a lower edge side opening part is uniquely performed after the purchaser of a net bag accommodates required goods. Examples of the closing means include a means for closing the part based on thermal welding, a means for closing with a stapler (trademark: stapler), or a means for closing the part into a bundled form bundled together with a string.

なお、既述した正面形成用フイルム状シート材１及び背面形成用フイルム状シート材２であるが、収容されている商品の正面部または背面部若しくは両方からの透視を図るために、当該フイルム状シート材の両者若しくは何れか一方を透明若しくは半透明のフイルム状シート材で形成することが好ましいが、これは絶対的な要件ではなく、非透明性のフイルム状シート材で形成して実施することも可能である。 In addition, although it is the film-form sheet material 1 for front formation mentioned above and the film-form sheet material 2 for back formation, it is the said film form in order to aim at see-through from the front part or back part, or both of the goods accommodated. It is preferable to form both or one of the sheet materials with a transparent or translucent film-like sheet material, but this is not an absolute requirement and should be carried out with a non-transparent film-like sheet material. Is also possible.

ａは上記した熱溶着部Ａの所要箇所に正面側から背面側に突き抜けるようにＵ字状に溶断またはプレス等に基づき切設したる吊り下用孔であって、商品の引掛け的展示、または、携行用持ち手として機能させるためのものであり、その形成形状は図示のものに限定されるものではなく、単なる穿設孔であっても良い。 a is a hanging hole cut in a U-shape so as to penetrate from a front side to a back side at a required portion of the above-described heat-welded portion A, and is a hanging display of products. Or it is for making it function as a carrying handle, and the formation shape is not limited to the illustrated one, and it may be a simple perforation hole.

本考案に係るネット袋は以上のような構成を有するものであって、図面に示すような形態で包装用袋として販売に供され、実際の商品販売に際しては、これの購入者によりネット袋内に対する商品の収容及び下端側開口部に対する閉塞処理を施した状態で行われるものである。 The net bag according to the present invention has the above-described configuration, and is provided for sale as a packaging bag in the form as shown in the drawings. This is performed in a state where the product is stored and the lower end side opening is closed.
