Abstract

<P>PROBLEM TO BE SOLVED: To easily and reliably open a plastic film-made packaging bag which is back-sealed by heat sealing. <P>SOLUTION: A packaging bag is formed of a thermally bonding type plastic film 1, and the plastic film 1 wrapping a content is heat-sealed at a back-sealed part 2 and an end-sealed part 3. A cut line 4 is formed astride the end-sealed part 3 from an end edge of the back-sealed part 2 over a base end line (a). When the back-sealed part 2 is picked and pulled, the plastic film 1 is torn from the cut line 4 from a content storing part, and the content storing part for the content is opened. <P>COPYRIGHT: (C)2008,JPO&INPIT

この発明は、ヒートシールにより背貼封緘したプラスチックフィルム製の包装袋であって、開封を容易にできるようにしたものに関する。  The present invention relates to a plastic film packaging bag back-sealed by heat sealing, which can be easily opened.

一般に、菓子等の包装袋として、図５に示すように、熱融着性を有するプラスチックフィルム５１を材料とし、内容物を包み込んだプラスチックフィルム５１を背貼シール部５２及び端シール部５３でヒートシールして封緘するピロー形式のものが使用されている。  In general, as a packaging bag for confectionery or the like, as shown in FIG. 5, aplastic film 51 having heat-fusibility is used as a material, and theplastic film 51 enclosing the contents is heated by a back-stickingseal portion 52 and anend seal portion 53. A pillow type that seals and seals is used.

このような包装袋は、内容物が多量に封入されている場合、開封に際し、袋の前面と背面とを摘んで端シール部５３を引き剥がそうとしても、袋に摘む余裕がなく、開封するのが難しい場合がある。  When a large amount of contents are enclosed, such a packaging bag is opened with no room for gripping theend seal 53 when the front and back surfaces of the bag are gripped and theend seal portion 53 is peeled off. It can be difficult.

その対策として、背貼シール部５２と端シール部５３の交差部に端縁からＶ字状の切込５４を入れ、図６に示すように、背貼シール部５２を摘んで引っ張ることにより、開封できるようにすることが考えられている（下記特許文献１参照）。  As a countermeasure, by inserting a V-shaped cut 54 from the end edge at the intersection of the backsticker seal portion 52 and theend seal portion 53, as shown in FIG. It has been considered to enable opening (seePatent Document 1 below).

しかしながら、上記のような包装袋では、製袋工程でのプラスチックフィルム５１の蛇行により、Ｖ字状の切込５４の谷が背貼シール部５２側へずれている場合、背貼シール部５２を引っ張って開封しようとしても、背貼シール部５２が千切れるようにプラスチックフィルム５１が裂け、内容物の収納部が開口しないことがある。  However, in the packaging bag as described above, when the valley of the V-shaped cut 54 is shifted to the back stickingseal part 52 side due to the meandering of theplastic film 51 in the bag making process, the back stickingseal part 52 is Even if an attempt is made to open it by pulling, theplastic film 51 may be torn so that the back-stickingseal part 52 is broken, and the contents storage part may not be opened.

そこで、この発明は、ヒートシールにより背貼封緘したプラスチックフィルム製の包装袋を、容易かつ確実に開封できるようにすることを課題とする。  Then, this invention makes it a subject to enable it to open the packaging bag made from a plastic film back-sealed by heat sealing easily and reliably.

上記課題を解決するため、この発明は、熱融着性を有するプラスチックフィルムを材料とし、内容物を包み込んだプラスチックフィルムを背貼シール部及び端シール部でヒートシールした包装袋において、背貼シール部の端縁から基端線を越えて端シール部へ跨るように、切目線を入れたのである。  In order to solve the above problems, the present invention provides a backseal seal in a packaging bag in which a plastic film having heat-fusibility is used as a material, and the plastic film enclosing the contents is heat-sealed at the backseal part and the end seal part. A cut line is made so as to extend from the end edge of the portion to the end seal portion beyond the base end line.

この包装袋では、背貼シール部を摘んで引っ張ると、切目線から内容物の収納部へかけてプラスチックフィルムが裂け、内容物の収納部が開口するので、内容物が多量に封入されていても、容易かつ確実に開封して、内容物を取り出すことができる。  In this packaging bag, when the back sticker seal part is picked and pulled, the plastic film tears from the score line to the content storage part, and the content storage part opens, so the contents are enclosed in large quantities. However, the contents can be taken out easily and reliably.

以下、この発明の実施形態を添付図面に基づいて説明する。  Embodiments of the present invention will be described below with reference to the accompanying drawings.

図１及び図２に示すように、この包装袋は、熱融着性を有するプラスチックフィルム１を材料とするピロー形式のものであり、菓子等の内容物を包み込んだプラスチックフィルム１を、背面の背貼シール部２及び両端縁に沿った端シール部３でヒートシールして封緘されている。  As shown in FIGS. 1 and 2, this packaging bag is a pillow type made of aplastic film 1 having heat-fusibility, and theplastic film 1 wrapped with contents such as confectionery is placed on the back surface. The back-sealedseal portion 2 and theend seal portion 3 along both end edges are heat-sealed and sealed.

そして、この包装袋には、一方の端部において、背貼シール部２の端縁から基端線ａを越えて端シール部３へ跨るように、斜め直線状の切目線４が入れられている。  And in this packaging bag, the diagonalstraight cut line 4 is put in one end part so that it may straddle theend seal part 3 over the base end line a from the edge of the backsticker seal part 2. Yes.

ここで、切目線４は、製袋工程でのプラスチックフィルム１の蛇行が基準位置に対して左右２ｍｍ程度生じる可能性があることから、基端線ａを中心として背貼シール部２と端シール部３とに２ｍｍ以上入る状態を基準として設定するとよい。  Here, since themeander line 4 may meander theplastic film 1 in the bag making process about 2 mm on the left and right with respect to the reference position, the backsticker seal portion 2 and the end seal are centered on the base line a. It is good to set it as a reference | standard for the state which enters into thepart 3 2 mm or more.

上記のような包装袋では、開封する際、図３に示すように、背貼シール部２を起こし、背貼シール部２を摘んで引っ張ると、図４に示すように、斜め直線状の切目線４から内容物の収納部へかけてプラスチックフィルム１が裂け、内容物の収納部が開口する。  When opening the packaging bag as described above, as shown in FIG. 3, when the back-stickingseal portion 2 is raised, and the back-stickingseal portion 2 is picked and pulled, as shown in FIG. Theplastic film 1 is torn from the line ofsight 4 to the content storage portion, and the content storage portion opens.

このため、内容物が多量に封入されていても、容易かつ確実に開封して、内容物を取り出すことができる。  For this reason, even if the content is enclosed in a large amount, it can be easily and reliably opened and the content can be taken out.

また、Ｖ字状の切込を入れた包装袋のように、製袋工程で抜き落とされなかった切滓が内容物の収納時に混入するおそれがなく、食品包装の安全性が向上する。  Moreover, there is no possibility that cutting chips that have not been removed in the bag-making process will be mixed in when the contents are stored, such as a packaging bag with a V-shaped cut, and the safety of food packaging is improved.

なお、上記実施形態では、包装袋の一方の端部にのみ切目線４を入れたが、両方の端部に切目線４を入れるようにしてもよい。  In addition, in the said embodiment, although thecut line 4 was put only in one edge part of a packaging bag, you may make it put thecut line 4 in both edge parts.

また、切目線４は、斜め直線状に入れたが、背貼シール部２を引っ張る際の力の作用方向を考慮して、湾曲した形状に入れてもよい。  Moreover, although thecut line 4 was put in the diagonal straight line shape, you may put it in the curved shape in consideration of the action direction of the force at the time of pulling the backsticker seal part 2.
