Description

【0001】
【考案が属する技術分野】
本考案は袋口の形状を自由に変形できる袋であり、より詳しくは袋口を閉じたり、全開したり、くちばし状の注ぎ口を設けた形状にしたり、様々に変形でき、その形状を長く保持できると共に、新たに別の形状に変形させることができる袋口の形状を一定に保持できる袋に関する。
【0002】
【従来の技術】
近時、プラスチック袋はその透明性、柔軟性、密封性、印刷適性、加工容易性等、多くの長所を有するため、生活のあらゆる分野で広く使用されている。袋の形状としては、二方シール袋、三方シール袋、ピロー袋、ガセット袋、スタンド袋等を挙げることができる。袋を製造するフィルムも1種類のプラスチックからなる単層フィルムの他、異種プラスチックフィルムを積層したり、紙、アルミニウム層等プラスチック以外の素材を積層した、それぞれの用途に応じて開発された各種ラミネートフィルムが広く使用されている。
【0003】
従来、袋に使用されるプラスチックフィルムは薄く、種々の形状に変化させられるが、その形状を保持することはできない。袋口を円形に広げて、袋を起立させても手を離すと袋は倒れて袋口は横を向いた形になる。一方、針金は各種形状に任意の部位から折曲げることができ、針金を袋口に通すことも考えられる。しかし、廃棄する場合に針金は金属で不燃物ゴミとなり、地球環境保護の上で好ましくない。プラスチックは燃やすことができ、特にポリオレフィンは燃焼の際有害ガスを発生しない。
【0004】
【考案が解決しようとする課題】
例えば、製品を袋詰めする工程等において、袋口が円形に全開した状態であれば作業がはかどる。ゴミ袋などでも袋口が全開していれば、投げ入れることができて便利であり、使用しない時には袋口を閉じることができる金属以外の素材、好ましくはプラスチック素材を袋口に接着又は融着したプラスチック袋が求められていた。
【0005】
【課題を解決するための手段】
本考案は上記課題を解決することを目的とし、その構成は、プラスチック袋の袋口に沿って、好ましくは袋口の外側に、プラスチック製、好ましくはポリオレフィン製の形状保持テープが融着又は接着されており、該形状保持テープは長さ方向に圧延延伸されたプラスチックテープであり、任意の部位を曲げた場合に、任意の角度に容易に曲がり、次に異なる曲げ角度に修正する力が加わるまでは、先の曲げ角度を保持することができる。
【0006】
すなわち、本考案はプラスチック製、特にポリオレフィン製で針金や薄い金属板のように任意の部位で任意の角度に折曲げることができ、この曲げ角度をそのまま保持することができ、他の角度に曲げたい場合には自由に曲がり、且つその角度を維持することができるような素材であり、しかもこの操作を何回でも繰返すことができる素材を、プラスチックの袋の袋口に固着したものである。
【0007】
【考案の実施の形態】
本考案のプラスチック袋は特に限定がない。大きさは一辺が3cm程度の小さいものから一辺が1m以上の大きいものまで使用できる。形状も二方シール袋、三方シール袋、ピロー袋、ガセット袋、スタンド袋等いずれも使用でき、縦、横の長さの比率も自由である。
【0008】
素材はポリエチレン、ポリプロピレン等のポリオレフィン、ポリ塩化ビニル、ポリスチレン、ポリエステル、ナイロン等が使用でき、これらを単層で或いは積層して使用する。或いはアルミニウム蒸着層、アルミニウム箔、紙、繊維等の異種素材を積層することもできる。又、ポバール、ポリ塩化ビニリデン、エバール等の異種プラスチック層を積層することもできる。
【0009】
本考案で使用するプラスチック製の形状保持テープは、ポリエチレン又はポリプロピレン等のポリオレフィンが好ましい。加熱溶融したペレットをTダイから押出し、長さ方向に強く圧延延伸することにより得られるフィルムである。このフィルムを必要な幅に延伸方向に切断したものを使用することができる。このようなフィルムは市販されており、例えばフォルテ(商品名、積水化学社製、ポリエチレン超延伸シート)等を購入することができる。このシートを延伸方向に必要幅に切断し、本考案の形状保持テープを得ることができる。
【0010】
袋口に形状保持テープを固着させるにあたっては、袋素材の外表面のフィルムと融着させることができる。この場合には袋の外表面のフィルムがポリオレフィン等の低い温度で軟化するフィルムである。ポリエステルやナイロン等低い温度で軟化しないフィルムに関しては接着剤を介して接着することができる。形状保持テープは袋の外側に固着させることが多いが、内側でもよく、或いは袋口を2つ折りし、その間に形状保持テープを挟み込み、形状保持テープの両面を接着或いは融着することができる。この場合もフィルムの折り方は外向きでも内向きでもよい。
袋口とは袋の開口部の先端部であるが、正確に先端部である必要はなく先端部近辺であればよい。
【0011】
形状保持テープの厚さは目的に応じて広い範囲で選択できるが、0.1mm〜2.0mmが好ましく、より好ましくは0.3〜1.0mmである。形状保持テープの幅も特に限定しないが1mm〜20mmが好ましく、より好ましくは3〜10mmである。好ましい厚さの形状保持テープを購入し、フィルムの圧延延伸方向と同一方向に、目的とする幅に切断すればよい。
【0012】
【実施例】
図1は袋口を最大に丸く広げた状態の斜視図、図2は本考案の袋の袋口を2つ折りし、更に2つ折りしたもので全体として4つ折り状態の斜視図である。図3は図1の破線で囲んだ部分の拡大断面図である。
【0013】
公演終了後の劇場の掃除において、横70cm、縦90cmの本考案袋2を、図1に示すように用意した。袋2はポリプロピレンの単層フィルムからなる袋であり、形状保持テープ1は厚さ3mmの積水化学社製のポリエチレン超延伸シート、フォルテを、幅1cmに樹脂の延伸方向に切断して得たものを使用した。3はフィルムであり、4は袋口である。形状保持テープ1は袋口4より若干奥に外面から融着した。5は形状保持テープ1と袋3との融着部である。
【0014】
袋口4を図1に示すように大きく開いた状態に保持することができるため、大部分のゴミは投げるだけで袋2内に入った。その後、細かい塵を箒で掃いて袋2内に投入した。次の場所に移動するとき、その距離が長い場合は持ち運びが不便なため、図2に示すように袋口4を4つ折りにして運んだ。勿論、2つ折りでも、8つ折りでもその場に応じて自由である。また、掃除をする場所にきた時には袋口4を再び図1に示すように大きく開いて作業を行った。その結果、作業効率が飛躍的に向上し、作業時間は従来の1/3程度短縮され、作業者の疲労も少なかった。
【0015】
【考案の効果】
袋口に形状保持テープを融着或いは接着する本考案により、袋口がどの部分でもあらゆる角度に変形可能であり、その変成した状態をいつまでも保持することができ、次に他の角度に変形したい場合は何度でも自由に変形することができ、袋の機能が飛躍的に向上した。

[Technical field to which the invention belongs]
The present invention is a bag capable of freely changing the shape of the bag mouth, and more specifically, the bag mouth can be closed, fully opened, a shape provided with a beak-shaped spout, can be variously deformed, and the shape can be lengthened. The present invention relates to a bag that can be held and can hold a shape of a bag mouth that can be newly deformed to another shape.
[0002]
[Prior art]
Recently, plastic bags have been widely used in all fields of life because of their many advantages such as transparency, flexibility, sealability, printability, and ease of processing. Examples of the shape of the bag include a two-side seal bag, a three-side seal bag, a pillow bag, a gusset bag, and a stand bag. The film used to make the bag is a single-layer film made of one kind of plastic, a different kind of plastic film, or a laminate made of non-plastic materials such as paper and aluminum layers. Film is widely used.
[0003]
Conventionally, a plastic film used for a bag is thin and can be changed into various shapes, but the shape cannot be maintained. Even if the bag mouth is spread out in a circular shape and the hand is released even if the bag is raised, the bag collapses and the bag mouth turns sideways. On the other hand, the wire can be bent into an arbitrary shape from an arbitrary portion, and the wire may be passed through a bag mouth. However, when discarded, the wire is made of metal and becomes incombustible garbage, which is not preferable in terms of global environmental protection. Plastics can be burned, especially polyolefins, which do not emit harmful gases when burned.
[0004]
[Problems to be solved by the invention]
For example, in a step of packing a product, the work is accelerated if the bag mouth is fully opened in a circular shape. If the bag mouth is fully open even in a garbage bag, it can be conveniently thrown in. When not in use, the bag mouth can be closed. A material other than metal, preferably a plastic material, is adhered or fused to the bag mouth. Plastic bags were required.
[0005]
[Means for Solving the Problems]
An object of the present invention is to solve the above-described problem, and the configuration is such that a plastic, preferably polyolefin-shaped shape-retaining tape is fused or adhered along a bag mouth of a plastic bag, preferably outside the bag mouth. The shape-retaining tape is a plastic tape that has been rolled and stretched in the longitudinal direction. When an arbitrary portion is bent, it is easily bent to an arbitrary angle, and then a force for correcting to a different bending angle is applied. Up to this point, the bending angle can be maintained.
[0006]
That is, the present invention is made of plastic, especially polyolefin, and can be bent at an arbitrary angle at an arbitrary portion, such as a wire or a thin metal plate, and this bending angle can be maintained as it is, and it can be bent to another angle. A material that can bend freely and maintain the angle when desired, and that can repeat this operation any number of times, is fixed to the opening of the plastic bag.
[0007]
[Embodiment of the invention]
The plastic bag of the present invention is not particularly limited. The size can be as small as about 3 cm on one side to as large as 1 m or more on one side. The shape can be any of a two-sided seal bag, a three-sided seal bag, a pillow bag, a gusset bag, a stand bag, and the like, and the ratio of length to width is free.
[0008]
The material may be a polyolefin such as polyethylene or polypropylene, polyvinyl chloride, polystyrene, polyester, nylon, or the like, and these may be used in a single layer or in a laminate. Alternatively, different kinds of materials such as an aluminum vapor-deposited layer, aluminum foil, paper, and fiber can be laminated. Further, different kinds of plastic layers such as poval, polyvinylidene chloride, and eval can be laminated.
[0009]
The plastic shape retaining tape used in the present invention is preferably a polyolefin such as polyethylene or polypropylene. This is a film obtained by extruding a heat-melted pellet from a T-die and strongly rolling and stretching in the length direction. What cut | disconnected this film to the required width | variety in the extending | stretching direction can be used. Such a film is commercially available, and for example, Forte (trade name, manufactured by Sekisui Chemical Co., Ltd., polyethylene ultra-stretched sheet) and the like can be purchased. This sheet is cut to the required width in the stretching direction to obtain the shape retaining tape of the present invention.
[0010]
In fixing the shape retaining tape to the bag mouth, it can be fused with the film on the outer surface of the bag material. In this case, the film on the outer surface of the bag is a film softened at a low temperature such as polyolefin. Films that do not soften at low temperatures, such as polyester and nylon, can be bonded via an adhesive. The shape-retaining tape is often fixed to the outside of the bag, but it may be inside, or the bag mouth may be folded in two, the shape-retaining tape sandwiched therebetween, and both sides of the shape-retaining tape may be adhered or fused. Also in this case, the film may be folded outward or inward.
The bag mouth is the tip of the opening of the bag, but does not have to be exactly the tip, but may be near the tip.
[0011]
The thickness of the shape retaining tape can be selected in a wide range depending on the purpose, but is preferably 0.1 mm to 2.0 mm, more preferably 0.3 to 1.0 mm. Although the width of the shape maintaining tape is not particularly limited, it is preferably 1 mm to 20 mm, more preferably 3 to 10 mm. What is necessary is to purchase a shape maintaining tape having a preferable thickness, and cut the tape into a desired width in the same direction as the rolling and stretching direction of the film.
[0012]

FIG. 1 is a perspective view showing a state in which the bag mouth is widened to the maximum, and FIG. 2 is a perspective view showing the bag of the present invention in which the bag mouth is folded in two and further folded in a four-fold state as a whole. FIG. 3 is an enlarged sectional view of a portion surrounded by a broken line in FIG.
[0013]
In cleaning the theater after the performance, a bag 2 of the present invention having a width of 70 cm and a length of 90 cm was prepared as shown in FIG. The bag 2 is a bag made of a single-layer film of polypropylene, and the shape-retaining tape 1 is obtained by cutting a 3 mm thick polyethylene ultra-stretched sheet manufactured by Sekisui Chemical Co., Ltd., forte to a width of 1 cm in the resin stretching direction. It was used. 3 is a film, and 4 is a bag mouth. The shape retaining tape 1 was fused from the outer surface slightly behind the bag opening 4. Reference numeral 5 denotes a fused portion between the shape retaining tape 1 and the bag 3.
[0014]
As shown in FIG. 1, the bag mouth 4 can be held in a widely opened state, so that most of the trash entered the bag 2 by simply throwing it. Thereafter, fine dust was swept with a broom and put into the bag 2. When moving to the next place, if the distance is long, it is inconvenient to carry, so as shown in FIG. 2, the bag opening 4 was folded and carried. Of course, folding in two or folding in eight is free depending on the situation. When the user came to the place to be cleaned, the user opened the bag opening 4 again as shown in FIG. As a result, the working efficiency has been dramatically improved, the working time has been reduced by about 1/3 of that of the prior art, and the fatigue of the worker has been reduced.
[0015]
[Effect of the invention]
By fusing or adhering the shape retaining tape to the bag mouth, the bag mouth can be deformed at any angle at any part, and the transformed state can be maintained forever, and then I want to deform it to another angle If the bag can be freely deformed as many times, the function of the bag is dramatically improved.
