【従来の技術】
厚みと広がりある物品の収納、整理袋には通常、方形シートを重ね縦横辺を封止した袋で、側部に単一ひだを入れ、空袋時には底部を曲げて袋面に重ねる型が多い。この単一ひだ袋は、折りひだが内部に大きく出て、物品を出し入れし難く、底部の折目に物品が残りやすく、収納に融通性が乏しく、充填半ばでは多様に膨らんですわりが悪く、出っ張る底外部は引っ掛かりやすい。例えば、マチ付き封筒（実登３０５４０３８、実開昭６０−１８４８４７、特開２００１−３０１７６１）、底マチ付き封筒（実開平０１−１４１２３０）、ひだ付き紙袋（特開２０００−３５５３３３）等が公知だが、いずれも単一ひだ袋であって収納容量巾の狭い利用に限られ、従って、立て並べ整理に適して柔軟な収納力のある袋は知られていない。
【０００３】
【発明が解決しようとする課題】
本発明は、上の不都合を解決する、収納物の出し入れ容易で、立て並べ整理に適する、柔軟な収納力のある複ひだ袋に関する。
【０００４】
【課題を解決するための手段】
上記目的を達成するために、側底部ひだ袋において、側部の複数縦ひだと、当該ひだに直交する底辺を有して連なる複数の三角形折線で当該側部を折り曲げて作る側部延長底部の複数ひだと、当該屈曲部及び底部ひだに嵌合する、袋面延長底部の複数ひだを構成要素とすることにより、複数の伸縮する浅いひだが収納物の量と形状への対応力に優れ、袋の腰が強くなり立て並べやすく、底部が緊密に嵌合された重層ひだ構造になって強度と形状保持性に優れた複ひだ袋を提案する。
【０００５】
本発明の複ひだ袋は、複数の伸縮する浅いひだと、緊密に嵌合された重層ひだ底を特徴とする。嵌合された重層ひだ底化により、屈曲部の製作が容易になり、袋面延長底部は糊付けしなくてもめくれず、素材の無駄を出さない。製作上乃至取扱い管理上からも、軽くて強靭な方形の紙袋素材、例えばクラフト紙が重用されるが、台形乃至上下異形の各種袋素材も使用できる。周囲どの位置でも糊代部を設けることができるが、側部端にすると、底形成部の最端部と同様に紙厚みを考慮して小幅にすることと併せて、すっきりした側部と底部折り込みを可能にする。ひだ数が多過ぎて畳み難くならないようなひだ幅でひだ数を増やす、異幅の複数側底部ひだで構成する、テープ等で補強する、上縁に蓋乃至折り返しや封緘構造を設ける、持ち手を付ける等、紙袋厚みを含めた寸法等も、目的に応じて総合的に選定できる。
【０００６】
本発明の複ひだ袋の製作方法は、複ひだに折る手間が増えるが、たとえば紙素材の場合、方形紙に予め折線をつけ、或いは型押し等して、折り癖をつけておくことで容易になる。その上で側部延長底部の両側に切り込みを入れ、当該側部を連なる複数の下向き三角形の底辺折線で折り曲げて作る側部延長底部の上に、面延長底部を重ねてから、側部ひだを底部ひだと共折りすることで、嵌合も容易になる。上向き三角形の底辺折線で折ると、側部延長底部のひだが側部に突出する。側部延長底部を袋内表に出すと、製作は容易になるが、用紙の型取りと底手当てで不利になることがある。望ましくは、側部延長底部一対を面延長底部一対の間に挟んでひだ折りする。こうすると、一方の面延長底部ひだの両端の折り込み部を側部屈曲部に強固に嵌合するので、他方の面延長底部まで屈曲部に嵌合する必要はない。必ずしも糊を用いずに嵌合したのち、面糊代を側部ひだに折り重ねて糊付けし、他方の面延長底部ひだを底部ひだに折り重ねて、少なくとも端ひだ部を糊付けする。底部及びその両端が分厚くなることを避けて、あるいは製作の便宜上、一部を切除することもできる。
【０００７】
本発明の複ひだ袋の形状とサイズ及び材質は、上記の特徴を満たして目的に応じて選択できるが、通常紙のほか、ラミネート紙やＰＥ，ＰＰ等ポリオレフィン類のプラスチックフィルム乃至シート、あるいは多孔シート、網状シート等からも製作できる。折線を付けて手折りにより、または部分乃至全体の型押し加工、両面テープやヒートシール等により糊付け製作できる。

BACKGROUND OF THE INVENTION
The present invention relates to a bag used for storage, organization, and the like.
[0002]
[Prior art]
For storing and organizing bags with thickness and spread, there are usually many types of bags that are stacked with rectangular sheets and sealed on the vertical and horizontal sides, with a single pleat on the side, and bent at the bottom to overlap the bag surface when empty. . This single pleat bag has a large fold, but it is difficult to put in and out the article, the article is likely to remain at the bottom fold, the flexibility of storage is poor, and it is inflated variously in the middle of filling. The protruding bottom outside is easy to get caught. For example, envelopes with gussets (Actual 3054038, Japanese Utility Model Application Laid-Open No. 60-184847, Japanese Patent Application Laid-Open No. 2001-301761), envelopes with bottom gussets (Japanese Utility Model Application Laid-Open No. 01-141230), pleated paper bags (Japanese Patent Application Laid-Open No. 2000-355333), etc. These are single pleat bags and are limited to the use with a narrow storage capacity width. Therefore, there is no known bag with a flexible storage capacity suitable for standing arrangement.
[0003]
[Problems to be solved by the invention]
The present invention relates to a double pleat bag having a flexible storage capacity, which solves the above inconvenience, is easy to put in and out stored items, and is suitable for side by side arrangement.
[0004]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, in the side bottom pleat bag, a side extension bottom portion formed by bending the side portion with a plurality of vertical folds on the side portion and a plurality of triangular folding lines having a base perpendicular to the folds. By using multiple pleats and multiple pleats at the bottom of the bag surface that fit into the bent and bottom pleats as components, it is excellent in the ability to handle the amount and shape of multiple foldable shallow folds, We propose a multi-pleat bag that has a multi-layered fold structure in which the bottom of the bag is strong and easy to line up, and the bottom is closely fitted, and has excellent strength and shape retention.
[0005]
The double pleat bag of the present invention is characterized by a plurality of shallow folds that expand and contract and a multilayer pleat bottom that is closely fitted. The bent folds that are fitted together make it easier to produce the bent part, and the bottom part of the bag surface extension does not turn without gluing, and material is not wasted. From the viewpoint of production and handling management, a light and tough rectangular paper bag material, for example, kraft paper is used, but various bag materials of trapezoidal shape and upper and lower shapes can also be used. The margin part can be provided at any position in the surroundings, but when it is at the end of the side, in the same way as the extreme end of the bottom forming part, the paper thickness is taken into consideration and the side and bottom are clean. Allows folding. Increasing the number of pleats with a pleat width that does not make it difficult to fold because there are too many pleats, composed of multiple side bottom pleats of different widths, reinforced with tape, etc., providing a lid or folding or sealing structure on the upper edge, handle The dimensions including the thickness of the paper bag can be selected comprehensively according to the purpose.
[0006]
The method of manufacturing the double pleat bag of the present invention requires more time and effort to fold the double pleats. For example, in the case of a paper material, it is easy to make a crease by making a fold line or embossing the square paper in advance. become. Then, make cuts on both sides of the side extension bottom, and fold the side extension bottom on the side extension bottom made by bending the side part at the bottom fold line of multiple downward triangles. Co-folding with the bottom folds also facilitates fitting. When folded at the bottom fold line of the upward triangle, it protrudes to the fold side of the bottom extended side. If the side extension bottom is put on the front side of the bag, the manufacture becomes easy, but there are cases where it is disadvantageous to mold the paper and cover the bottom. Desirably, the pair of side extended bottom portions is folded between the pair of surface extended bottom portions. In this case, the folded portions at both ends of the one surface extension bottom pleat are firmly fitted to the side bent portion, and therefore it is not necessary to fit the bent portion to the other surface extended bottom portion. After fitting without necessarily using glue, the surface glue margin is folded and glued on the side folds, and the other surface extension bottom fold is folded on the bottom fold, and at least the end folds are glued. A part of the bottom part and both ends thereof can be cut away to avoid thickening or for convenience of manufacturing.
[0007]
The shape, size and material of the double pleat bag of the present invention can be selected according to the purpose while satisfying the above-mentioned characteristics. In addition to normal paper, polyolefin paper such as laminate paper, PE, PP, or porous It can also be manufactured from sheets, mesh sheets, and the like. It can be glued by hand-folding with a fold line or by partial or whole embossing, double-sided tape or heat sealing.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the invention will be described with reference to the drawings.
In FIG. 1, craft paper having a length of 34 cm and a width of 44 cm is provided with four 1.6 cm wide vertical folding lines for the side folds (1) from the left end, 15 cm for the front side (2), and further side folds (3 ), 5 vertical fold lines with a width of 1.6 cm, 15 centimeters for the rear surface (4), and a vertical fold line for paste margin (5) at 1.2 cm from the right end. A horizontal folding line for the bottom is made 6 cm from the lower end, and a cut (6) is made at the three boundaries of the side extended bottom fold (1a) and the front extended bottom fold (2a). A downward-facing triangular fold line (1b, 3b) is attached to the bent portion of the side extended bottom fold (1a, 3a), and a fitting triangular fold line (2b) is attached to both ends of the front extended bottom fold (2a). An extended bottom fold (4a) and a fold line (4b) are also attached to the rear surface (4) and glue margin (5), and both ends are folded. For pleats, a fold line with a width of 1.2 cm is attached from the lower end, and two fold lines with a width of 1.6 cm each are formed thereon. After folding each fold line into a mountain fold (solid line) and a valley fold (dotted line) and attaching a crease, on each side extension bottom (1a, 3a) made by folding at a right angle at the bottom fold line of each two downward triangles, The front extended bottom (2a) is overlaid and the side folds are folded together with the bottom folds and fitted. The margin (5) is glued to the end folds of the side folds (1), the rear extended bottom folds (4a) are overlaid on the side extended folds (1a, 3a), and the end folds are glued.
[0009]
【The invention's effect】
Since the present invention is configured as described above, it is easy to put in and out the stored items, and it is difficult for the stored items to be sandwiched between the shallow folds. Since the bottom portion has a multi-layer structure in which the bottom portions are closely fitted, the bag is excellent in strength and shape retention. Since both empty bags and filled bags are uniform, they can be arranged and arranged and stacked stably. In other words, as a flexible bag with flexible storage capacity, such as shelf-lined envelopes, boxed bags, pharmaceutical dispensing bags, and sachets, it is suitable for organizing, storing, and using a wide range of articles. Convenient.
