Description

本発明は、開口が容易にできる食品用包装袋に関する。    The present invention relates to a food packaging bag that can be easily opened.

平成１５年１１月５日付で同出願人による、開口が容易にできる食品用包装袋の特許出願があり、その出願のおいては、ミシン目の一辺が迂曲した形状、その迂曲が複数の形状、三角形状、四角形状などのミシン目を入れた開口が容易にできる食品用包装袋となっている。    On November 5, 2003, the applicant filed a patent application for a food packaging bag that can be opened easily. In that application, the shape of one side of the perforation is curved, and the curved shape is a plurality of shapes. It is a food packaging bag that can be easily opened with a perforation such as a triangular shape or a rectangular shape.

従来の食品を密封収容する包装袋は、開口縁に直線のミシン目とチャック部を設けていた為、袋を閉じると密着状態となり開口部が開け難い問題があった。    The conventional packaging bag for hermetically storing food has a straight perforation and a chuck portion at the opening edge. Therefore, when the bag is closed, the packaging bag is brought into a close contact state and it is difficult to open the opening portion.

本発明は、食品を密封収容する包装袋の開口縁となるミシン目において、袋本体の開口部にチャック部を設け、チャック部に近接した上部でミシン目を弓形に設け、開口時にミシン目を引裂によって袋本体の開口縁となり、ミシン目が湾出し対称となる開口縁を形成し、密着状態の開口部を開け易くし、開口が容易にできる食品用包装袋の提供を目的とするものである。    The present invention provides a perforation which is an opening edge of a packaging bag for hermetically containing food, and a chuck portion is provided at the opening of the bag body, and a perforation is provided in a bow shape at an upper portion adjacent to the chuck portion. It is intended to provide a food packaging bag that can be easily opened by forming an opening edge of the bag body by tearing, forming an opening edge in which the perforation is stubborn and symmetric, making the opening in a close contact state easy to open is there.

前記の課題を達成するため、食品を密封収容する包装袋において、熱接着性合成樹脂フィルムを用いて袋本体を形成し、その袋本体の開口部にチャック部を設け、チャック部に近接した上部でミシン目を弓形に設け、開口時にミシン目を引裂によって袋本体の開口縁となり、ミシン目が湾出し対称となる開口縁を形成した手段を講ずる。    In order to achieve the above-mentioned problem, in a packaging bag for containing food in a hermetically sealed manner, a bag body is formed using a heat-adhesive synthetic resin film, a chuck portion is provided in the opening of the bag body, and an upper portion close to the chuck portion. At the time of opening, a perforation is formed in the bag body by tearing the perforation at the time of opening, and a means of forming an opening edge in which the perforation is squeezed symmetrically is taken.

また、袋本体の開口縁となる弓形のミシン目が、開口時にミシン目を引裂によって形成される弓形の頂点部位が任意で対称となるようにしている。    Further, the arcuate perforation serving as the opening edge of the bag main body is configured such that the arcuate apex portion formed by tearing the perforation when opening is arbitrarily symmetrical.

本発明の、開口が容易にできる食品用包装袋により、密着状態の開口部を開け易くしたとともに、スムーズな開閉により袋内に収容された食品の鮮度の保持にも有用なものである。    The food packaging bag according to the present invention that can be easily opened makes it easy to open the opening in a close contact state, and is useful for maintaining the freshness of the food contained in the bag by smooth opening and closing.

発明の実施するための最良の形態を実施例にもとづき図面を参照して説明する。図１で示す実施例では、食品を密封収容する包装袋において、熱接着性合成樹脂フィルム１を用いて袋本体２を形成し、その袋本体２の開口部３にチャック部４を設け、チャック部４に近接した上部でミシン目５を弓形６に設け、開口時にミシン目５を引裂によって袋本体２の開口縁７となり、ミシン目２が湾出８し対称となる開口縁７を形成している。    The best mode for carrying out the invention will be described with reference to the drawings based on the embodiments. In the embodiment shown in FIG. 1, a bag body 2 is formed by using a heat-adhesive synthetic resin film 1 in a packaging bag for hermetically containing food, and a chuck portion 4 is provided in an opening 3 of the bag body 2. A perforation 5 is provided in an arcuate shape 6 at an upper portion close to the portion 4, and the perforation 5 is torn to become an opening edge 7 of the bag body 2 at the time of opening, and the perforation 2 protrudes 8 to form a symmetrical opening edge 7. ing.

また、図２で示す実施例では、袋本体２の開口縁７となる弓形６のミシン目５が、開口時にミシン目５を引裂によって形成される弓形６の頂点部位９が任意で対称となるようにしている。    Further, in the embodiment shown in FIG. 2, the perforation 5 of the arc 6 that becomes the opening edge 7 of the bag body 2 is arbitrarily symmetrical with the apex portion 9 of the arc 6 formed by tearing the perforation 5 when opening. Like that.

上記のような構成により、袋本体２のミシン目５が引裂によって開口縁７となり、その開口縁７で対称となる頂点部位９を、開口時にそれぞれ指で摘み左右に引くだけで容易に開口ができるものである。    With the configuration as described above, the perforation 5 of the bag body 2 becomes an opening edge 7 by tearing, and the opening 9 can be easily opened by simply picking the vertices 9 which are symmetric at the opening edge 7 with each finger at the time of opening and pulling left and right. It can be done.
