Description

本発明は、容易に引き裂いて開封することができ、引き裂いて開封した際の引裂き開封線が美麗であると共に引裂き開封線の位置が異なることにより、手指で容易に開口することができる包装袋に関するものである。   The present invention relates to a packaging bag that can be easily torn and opened, and that can be opened easily with fingers by tearing and opening when the tear opening line is beautiful and the position of the tear opening line is different. Is.

従来から、色々な形態の包装袋に種々の内容物が収容されて販売されている。そして、包装袋には、通常、挟み等の道具を使うことなく、手指で引き裂いて内容物を取り出すことができるように開封開始手段および/ないし開封手段が施されている。開封開始手段としては、包装袋の熱接着部外縁に設けられた、例えば、I字状やV字状、U字状、亀甲状等の切欠、あるいは、傷痕群等を挙げることができ、開封手段としては、包装袋を構成する積層体の少なくとも一つの層を残していずれかの層ないし複数の層に設けられた、たとえば、切目やミシン目、あるいは、包装袋を構成する積層体のいずれかの層に一軸延伸フィルムを設けたもの等を挙げることができる。   Conventionally, various contents are packaged and sold in various forms of packaging bags. The packaging bag is usually provided with an opening start means and / or an opening means so that the contents can be taken out by fingers without using a tool such as a pinch. Examples of the opening start means include notches such as I-shape, V-shape, U-shape, and turtle shell-shape provided on the outer edge of the heat-bonding portion of the packaging bag, or scars, etc. As a means, for example, either a cut line or a perforation provided in any layer or a plurality of layers leaving at least one layer of the laminate constituting the packaging bag, or any of the laminates constituting the packaging bag Examples of such a layer include a uniaxially stretched film.

たとえば、上記した開封開始手段を設けた四方シールタイプ包装袋は、開封開始は容易であるが、引裂きを続行すると包装袋を構成する積層体を無理に引き裂くことになり、結構強い力で引き裂かねばならないために、開封操作が煩雑であるという問題、あるいは、引き裂いた際の引裂き開封線が一定の形状ではなくて成り行きとなるために開封口が見苦しいという問題がある。   For example, a four-side-seal type packaging bag provided with the above-described opening start means is easy to start opening, but if tearing is continued, the laminate constituting the packaging bag will be forcibly torn and must be torn with a fairly strong force. Therefore, there is a problem that the opening operation is complicated, or there is a problem that the tear opening line is not a constant shape when it is torn and the opening is unsightly.

また、たとえば、上記した開封手段あるいは開封開始手段と開封手段を設けた四方シールタイプ包装袋は、開封開始手段から容易に引き裂くことができると共に開封手段により包装袋を構成する一方の積層体と他方の積層体の引裂き開封線がほぼ面一の状態で開封されるために開封口が美麗である反面、内容物を取り出す際に包装袋を構成する前記一方と他方の積層体を摘むことが結構煩雑となり、開口し難いという問題がある。   Further, for example, the four-side seal type packaging bag provided with the opening means or the opening start means and the opening means can be easily torn from the opening start means, and one laminated body constituting the packaging bag by the opening means and the other Since the tear opening line of the laminate is opened in a substantially flush state, the opening is beautiful, but when taking out the contents, the one and the other laminate constituting the packaging bag can be grasped. There is a problem that it becomes complicated and difficult to open.

そこで、容易に引裂き開封することができると共に、内容物を取り出す際に包装袋を構成する前記一方の積層体と他方の積層体を容易に摘むことができて容易に開口することができる包装袋が提案されている(たとえば、特許文献1参照)。この特許文献1に開示された技術は、包装袋を開封開始端から引き裂くと、包装袋を構成する一方の積層体と他方の積層体の面が引裂き方向に沿って互いに引裂き開封線が乖離する方向に引き裂かれるように構成した包装袋であり、前記一方と他方の積層体を容易に摘むことができ、内容物を取り出す際の開口を容易にするものである。   Therefore, a packaging bag that can be easily torn and opened, and can be easily opened by easily picking up the one laminate and the other laminate constituting the packaging bag when taking out the contents. Has been proposed (see, for example, Patent Document 1). In the technique disclosed in Patent Document 1, when the packaging bag is torn from the opening start end, the surface of one laminated body and the other laminated body constituting the packaging bag is torn apart from each other along the tearing direction and the unsealing line is separated. The packaging bag is configured to be torn in the direction, and the one and the other laminated body can be easily picked, and the opening for taking out the contents is facilitated.

しかしながら、特許文献1の包装袋は、不連続な切れ目を多数配置した構成からなるものであり、引裂き開封線が常に一定の形状には成り難く、また、引裂き開封線がジグザグ(zigzag)に形成されるために、開封口が見苦しいという問題や、たとえば、包装袋が剛性を有する積層体からなる場合、前記一方と他方の積層体を手指で摘む際、あるいは、開口から手指を入れて内容物を取り出す際等に、ジグザグ(zigzag)に形成された引裂き開封線の先端で痛みを覚えたり、あるいは、傷を負う虞がある。
WO01−062616号公報
However, the packaging bag of Patent Document 1 has a configuration in which a large number of discontinuous cuts are arranged, and the tear opening line is not always formed into a constant shape, and the tear opening line is formed in a zigzag shape. For example, if the packaging bag is made of a rigid laminate, the contents may be put in the fingers when the one and the other laminate are picked with fingers, or through the opening. When taking out, etc., there is a risk that the tip of the tear opening formed in a zigzag may be painful or injured.
WO01-0662616
