Description
【考案の詳細な説明】 〔産業上の利用分野〕 この考案は包装袋に関し、特に、サンドイッチを収納
するのに適した包装袋に関するものである。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a packaging bag, and more particularly to a packaging bag suitable for storing sandwiches.
一般に、サンドイッチ等の包装袋として種々のものが
提案されており、それらのほとんどは良好なる開封性を
得るようにしたものであり、そして、それらは2枚のフ
ィルムを用いて下底を開口部にするとともに、下底以外
の3辺をシールして台形状の袋としたものである。In general, various types of packaging bags for sandwiches and the like have been proposed, most of which are designed to obtain good opening properties, and they use two films to form an opening at the bottom. In addition, the three sides other than the lower bottom are sealed to form a trapezoidal bag.
しかしながら、サンドイッチ等に用いる包装袋は、薄
くて柔らかいフィルムのものがフィルム越しにサンドイ
ッチ等を掴んだ場合に柔軟性があるので一般には好まれ
てはいるが、逆に袋詰めが行い難く、かつ、輸送時に包
装袋の角に当たる部分のサンドイッチ等の内容物が潰れ
易いという問題点を有していた。However, a packaging bag used for sandwiches or the like is generally preferred because a thin and soft film is flexible when gripping the sandwich or the like through the film, but conversely it is difficult to carry out bagging, and However, there is a problem in that the contents such as sandwiches at the corners of the packaging bag are easily crushed during transportation.
この考案の目的はサンドイッチ等の柔らかい内容物を
収納できるとともに、収納物の角部が潰れたりするのを
防止することのできる包装袋を提供することである。An object of the present invention is to provide a packaging bag that can store soft contents such as sandwiches and can prevent the corners of the stored items from being crushed.

他端との間を溶断シールして、下底を開口部に形成し、
収納したサンドイッチの角部が両折り返し部に位置する
ように構成したものであり、前記折り返し部は、その幅
を20mm以下としたものである。In order to achieve the above-mentioned object, the present invention folds two long films having a heat-sealing property with a predetermined interval and with a predetermined width, and heat-seals the folded-back portion. A pair of strip-shaped folded portions are formed, and two films thus formed are polymerized in a state where the folded portions are aligned with each other, and when both films are melt-cut into a trapezoidal shape, both ends are respectively separated from the folded portions. Assuming a lower bottom located outside and matching one side edge of the long film, and an upper bottom parallel to this lower base and having both ends serving as folded portions, the upper base, the upper A fusion seal is formed between one end of the bottom and one end of the bottom bottom, and between the other end of the top bottom and the other end of the bottom bottom to form the bottom bottom in the opening,
The sandwiched corners of the stored sandwich are positioned at both folded portions, and the folded portion has a width of 20 mm or less.
この考案は上記の手段を採用したことにより、折り返
されてヒートシールされている折り返し部の強度が高め
られ、内部に収納されるサンドイッチは、一番潰れ易
く、また崩れ易い角部が折り返し部に当接した状態とな
るので輸送等の途中で潰れたり崩れたりするのが防止さ
れるものである。This invention adopts the above-mentioned means, so that the strength of the folded-back portion that is folded back and heat-sealed is enhanced, and the sandwich that is stored inside has the most easily crushable and fragile corners at the folded-back portion. Since they are in contact with each other, they are prevented from being crushed or collapsed during transportation or the like.
以下、図面に示すこの考案の実施例について説明す
る。An embodiment of the present invention shown in the drawings will be described below.
第2図にはこの考案による包装袋を製造するためのフ
ィルムの状態が示されている。FIG. 2 shows a state of a film for manufacturing the packaging bag according to the present invention.
このフィルムは長尺であるとともに、ヒートシール性
を有する、たとえば、ポリオレフィンフィルム(共押出
しの場合も含む)1を用い、このポリオレフィンフィル
ム1の2ヶ所を所定の幅で折り返し、この折り返した部
分をヒートシール3、3して一対の折り返し部2、2を
形成し、このようにして所定の間隔をおいて所定幅の一
対の折り返し部2、2が形成されたフィルムを作る。This film is long and has a heat-sealing property. For example, a polyolefin film (including a case of co-extrusion) 1 is used, two portions of the polyolefin film 1 are folded back with a predetermined width, and the folded portion is A pair of folded-back portions 2 and 2 is formed by heat-sealing 3 and 3, and a film in which a pair of folded-back portions 2 and 2 having a predetermined width is formed at a predetermined interval in this manner is produced.
なお、上記のヒートシール3する2ヶ所の折り返し部
2の幅はそれぞれ20mm以下が好ましいものであり、製造
の都合によっては折り返し部2の先端を切断することに
より幅を決定しても良い。It is preferable that the widths of the two folded portions 2 that form the heat seal 3 are 20 mm or less, and the width may be determined by cutting the tip of the folded portions 2 depending on the manufacturing convenience.
そして、上記のようにして形成したフィルム1、1を
2枚用いて互いに折り返し部2、2の間に位置する部分
4、4が外側に位置するようにして重合するとともに、
この重合した状態で第3図の鎖線で示すように両折り返
し部2、2間が上底となるような台形状に溶断シール5
する。」を「第3図の鎖線で示すように、両端が各折り
返し部2、2よりもそれぞれ外方に位置するとともに、
長尺のフィルムの一側縁に合致する下底と、この下底と
平行であるとともに、両端が各折り返し部2、2となる
上底とを想定する。Then, using the two films 1 and 1 formed as described above, the portions 4 and 4 located between the folded portions 2 and 2 are polymerized so that the portions 4 and 4 are located outside, and
In this superposed state, as shown by the chain line in FIG. 3, the fusing seal 5 has a trapezoidal shape with the upper bottom between the two folded portions 2.
To do. "As shown by the chain line in FIG. 3, both ends are located outside the respective folded-back portions 2 and 2, and
It is assumed that there is a lower bottom that matches one side edge of the long film and an upper bottom that is parallel to the lower bottom and has both ends serving as the folded portions 2 and 2.
つぎに、前記上底、上底の一端と下底の一端との間、
および上底の他端と下底の他端との間を溶断シール5し
て台形状に形成する。Next, between the upper bottom, one end of the upper bottom and one end of the lower bottom,
A fusing seal 5 is formed between the other end of the upper bottom and the other end of the lower bottom to form a trapezoidal shape.
したがって、この台形状に溶断シールした状態にあっ
ては、下底のみがシールされない状態であり、この下底
が開口部に形成されることとなる。Therefore, when the trapezoidal shape is fusion-sealed, only the lower bottom is not sealed, and the lower bottom is formed in the opening.
上記のようにした形成した包装袋にあっては、サンド
イッチを収納した場合には第1図に示すように広げら
れ、これによってサンドイッチの4つの角部にはヒート
シール3した前記折り返し部2が位置している。In the packaging bag formed as described above, when the sandwich is stored, it is unfolded as shown in FIG. 1, whereby the four folded portions 2 which are heat-sealed 3 are provided at the four corners of the sandwich. positioned.
したがって、上記のような状態にあっては、サンドイ
ッチのうちの潰れやすい角部が前記折り返し部で保護さ
れているので輸送時に潰れる恐れがないものである。Therefore, in the above-mentioned state, since the crushable corner portion of the sandwich is protected by the folded-back portion, there is no risk of crushing during transportation.
なお、前記実施例においては、折り返し部2、2間に
位置する部分4が互いに外側に位置するようにして2枚
のフィルム1、1を重合した場合について説明したが、
これに限定することなく、折り返し部2、2間に位置す
る部分4を内側に位置しても良く、フィルム1、1の重
合状態は問わないものである。In addition, in the said Example, although the part 4 located between the folding | returning part 2 and 2 was located outside mutually, the case where two films 1 and 1 were superposed | polymerized was demonstrated,
Without being limited to this, the portion 4 located between the folded-back portions 2 and 2 may be located inside, and the superposed state of the films 1 and 1 does not matter.
この考案は前記のように構成したことにより以下のよ
うな効果を有する。This device has the following effects by being configured as described above.
内部にサンドイッチを収納した際にはサンドイッチ
のうちの最も崩れやすい角部にフィルムを折り返して強
度を高く形成した折り返し部が当接するようにしたの
で、輸送等の途中でサンドイッチが崩れる恐れが無くな
った。When the sandwich was stored inside, the film was folded back at the corners of the sandwich that were most prone to collapse, so that the folded portion formed with high strength came into contact, so there was no risk of the sandwich collapsing during transportation. .
また、長尺のフィルムを所定の間隔を置いて折り返
して折り返し部を形成し、このようなフィルムを2枚重
合し、3辺を溶断シールすることで形成できるので、連
続的に次々と製造することができて作業効率が良好であ
る。Further, since a long film can be folded back at a predetermined interval to form a folded-back portion, two such films can be polymerized, and three sides can be fused and sealed, so that they can be continuously manufactured one after another. The work efficiency is good.
さらに、上底を長尺のフィルムの一方の側縁部とす
れば、フィルムの全幅を用いることができ、しかも、上
底と下底とをフィルムの流れ方向に対して交互に形成す
るようにすれば、フィルムを全く無駄にすることなく包
装袋を製造することも可能となり製造コストを著しく低
減することができる。Further, if the upper bottom is one side edge of the long film, the entire width of the film can be used, and furthermore, the upper bottom and the lower bottom are alternately formed in the film flow direction. Then, it is possible to manufacture a packaging bag without wasting the film at all, and the manufacturing cost can be significantly reduced.
