[0002]

[Prior art]

 Conventionally, sandwiches in which vegetables, ham, eggs, tuna, and the like are sandwiched between sliced breads have been widely sold at convenience stores and grocery stores. This sandwich is cut and cut into an appropriate shape such as a triangle, and is distributed and sold in a state where several sets are packaged in a food packaging bag made of a transparent plastic film.

As shown in FIG. 5 and FIG. 6, a conventional food packaging bag 21 such as a sandwich used for the above-mentioned application has a vertically long trapezoidal shape formed by laminating two plastic films, a front film 22 and a back film 23. It is punched into a shape, and the bottom side of the trapezoid is opened as an opening 24 and three sides excluding the bottom side are heat-welded to form side-side seal portions 25 and 26 and an upper-side seal portion 27 to form a bag. The upper side seal portion 27 is provided slightly inside the upper side end of the trapezoidal bag. Further, in order to facilitate opening of the bag, a narrow opening tape 31 is laminated from the upper end to the lower end at the center in the width direction on the back side of the back film 23, and is disposed above the upper side seal portion 27. In the back film 23, an opening cut line 28 is provided along both ends of the opening tape 31 to form a narrow photographing piece 30, and the surface film 22 above the upper side seal portion 27 is The whole is formed as a wide photographing piece 29. Since the conventional food packaging bag 21 is configured as described above, if the photographing piece 29 and the photographing piece 30 are taken and pulled, the back film 23 is cut open along both ends of the opening tape 31. It was possible to take out food such as sandwich.

On the other hand, in order to open the food package packaged using the conventional food packaging bag 21 such as a sandwich and to take out the sandwich or the like, the photographing piece 30 is provided by pulling the photographing piece 30. After tearing the center of the film surface in the width direction, the sandwich or the like could not be taken out unless the film surface was opened right and left. In other words, removing a sandwich from a conventional food packaging bag requires three steps of tearing the film surface, opening the film surface to the left and right, and removing the sandwich, etc. He was still crippled in point.

Further, since the photographed piece 30 of the conventional food packaging bag 21 is small and inconspicuous, it is troublesome to find the photographed piece 30. Further, in order to open the conventional food packaging 21, the photographing piece 29 and the photographing piece 30 must be carefully photographed before they can be opened. That is, since the photographing piece 30 of the conventional food packaging 21 is formed of a film having a small width, the food such as a sandwich is grasped with one hand, and the photographing piece 30 is photographed with the other hand and opened. There is a disadvantage that the taking piece 30 is cut off when sealed, and there is a risk that the food may be damaged if the opening is forcibly opened.
