No. 7-52025

  Then, this invention makes it a subject to provide the triangular food packaging body which can open a bag large at the time of opening and can take out triangular food easily.

  In order to solve the above problems, the present invention takes the following technical means.

  The triangular food packaging body of the present invention is a triangular food packaging body in which a triangular food product 4 is accommodated in a bag 3 composed of a front film 1 and a back film 2 having a shape in which the lower part is widened from the upper part. It has a heat seal portion 5 between the front film 1 and the back film 2 at the top, and has fusing seal portions 6 and 7 between the front film 1 and the back film 2 at the left and right edges, and the front film 1 is triangular. One surface 4a of the food 4 is covered, and when the upper end 1a of the front film 1 is pulled at the time of opening, the front film 1 and the back film 2 of the heat seal part 5 are peeled off, and the left and right fusing seal parts 6 7 are torn downward.

  Furthermore, the heat seal part 5 can be formed in a corrugated shape.

  Moreover, the heat seal part 5 can also be formed in the mountain shape where a top part is located in the approximate center of the width direction.

  The triangular food packaging body of the present invention has the above-described configuration. When the front film 1 and the back film 2 are torn by the fusing seal portions 6 and 7 on the left and right sides, the front food film 1 is covered with the front film 1. Since the opening is larger than the left and right widths of the surface 4a of the triangular food 4, the triangular food 4 can be easily taken out.

  Preferred embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an explanatory view of a triangular food packaging bag 3 according to an embodiment of the present invention, FIG. 2 is a perspective view of the triangular food packaging body, and FIG. 3 is a perspective view showing a state of opening the triangular food packaging body. It is.

  This triangular food packaging body is a triangular food packaging body in which a triangular food product 4 is accommodated in a bag 3 composed of a front film 1 and a back film 2 having a shape in which the lower part is expanded from the upper part. It has the heat seal part 5 of the front film 1 and the back film 2, and shall have the fusing seal parts 6 and 7 of the front film 1 and the back film 2 on the left and right edges, and the front film 1 is a triangular food 4 When the upper end 1a of the front film 1 is pulled at the time of opening, the front film 1 and the back film 2 of the heat seal part 5 are peeled off, and the left and right fusing seal parts 6, 7 are covered. Is torn downward.

  The front film 1 is a film that is pulled away from the triangular food 4 when the upper end of the front film 1 is opened, and is not necessarily located on the front side of the package that is displayed as a product. The relationship is not limited to the illustrated embodiment. In this embodiment, one surface of the triangular food 4 that covers the entire surface film 1 is configured to be an inclined surface 4 a that holds the longest two sides of the triangular food 4 on both the left and right sides. It may be a surface.

  Both the front film 1 and the back film 2 are made of OPP (biaxially oriented polypropylene) with a thickness of 30 μm, and the inner surfaces of each film can be heat-sealed and have an easy-open property that can be easily peeled off from the heat-sealed state. It is said. In order to prevent someone from opening the bag 3 and mixing in foreign matter without permission, it is desirable that the film be whitened when the seal portion is peeled off. As a film satisfying such conditions, for example, “ES1” which is an easy-open seal film of Gunze Co., Ltd. can be used.

  Moreover, the front film 1 and the back film 2 can be printed with appropriate characters and patterns.

  Both the front film 1 and the back film 2 have an acute isosceles triangle that is long in the vertical direction as a basic shape, and a hexagon that is formed by cutting out the upper end and the left and right ends. However, the front film 1 has a slightly shorter vertical dimension than the back film 2 so that the back film 2 is exposed at the upper and lower ends of the bag 3.

  The bag 3 is formed by fusing the front film 1 and the back film 2 and thermally fusing to form the fusing seal portions 6 and 7 at the left and right edges, and the front film 1 and the back film 2 are slightly below the upper edge. It is comprised by forming the heat seal part 5 which the inner surface of adhered.

  The fusing seal portions 6 and 7 extend between both ends of the upper end portion of the front film 1 and the left and right ends, and the heat seal portion 5 extends between the left and right edges of the front film 1 and the back film 2. It is said. Moreover, the heat seal part 5 is assumed to be formed in a wave shape in which a plurality of peaks and valleys are continuous, as shown in an enlarged view in FIG.

  The bag 3 before accommodating the triangular food 4 has an opening at the lower end, from which the triangular food 4 is accommodated, and the front film 1 and the back film 2 at the lower end are folded and overlapped, and a label or tape The triangular food packaging body is completed by stopping with etc. The front film 1 and the back film 2 are creased as shown so as to follow the outer shape of the triangular food 4.

  Note that the triangular food 4 is a commonly used triangular sandwich, that is, a food such as vegetables, eggs, and ham sandwiched between a plurality of breads and cut so that the left and right surfaces are right triangles. However, as long as the outer shape is formed in a triangular sandwich shape, it may be made of cooked rice or the like, and the material and size are not particularly limited.

  The front film 1 covers the entire slope 4a (cut surface) of the triangular food 4 and is bent so that the left and right side portions thereof overlap with the left and right triangular surfaces of the triangular food product 4, respectively, and the lower end is triangular. The shaped food 4 is bent so as to overlap the front side of the bottom surface. The back film 2 covers the entire rear surface of the triangular food 4, and the left and right sides thereof are folded so as to overlap the left and right triangular surfaces of the triangular food 4, and the lower end is the bottom of the triangular food 4. It is bent so as to overlap the rear side.

  In the triangular food package thus completed, the left and right fusing seal portions 6 and 7 pass from the vicinity of the left and right tops of the triangular food 4 to the center of the bottom surface through the left and right triangular surfaces, respectively. It is located all the way.

  The heat seal portion 5 is located slightly above the top of the triangular food 4. The upper end portion of the bag 3 above the heat seal portion 5 protrudes above the triangular food 4 so that the front film 1 and the back film 2 overlap each other.

  When opening the triangular food package, first, the upper end 1a of the front film 1 of the bag 3 is picked with fingers. At the upper end of the bag 3, the front film 1 and the back film 2 are overlapped, but their upper end edges are not aligned, so that the upper end 1a of the front film 1 can be easily picked.

  And if the upper end part 1a of the surface film 1 is picked and the surface film 1 is pulled away from the triangular food 4, the left and right fusing seal parts 6 and 7 near the upper end part 1a are torn downward. Go. At this time, the upper end of the back film 2 may be picked and supported by the finger of the other hand. When the left and right fusing seal portions 6 and 7 are torn to the position of the heat seal portion 5, the front film 1 and the back film 2 in the heat seal portion 5 are peeled, and then the remaining fusing seal portions 6 and 7 are directed downward. Torn.

  As described above, the heat seal portion 5 has a corrugated shape, and since the front film 1 and the back film 2 are partially peeled from the top of each mountain, the heat seal portion 5 is linearly formed. It is possible to open with less force.

  Moreover, since the left and right fusing seal portions 6 and 7 are formed on the left and right sides of the front film 1 and the back film 2 having a shape in which the lower portion is wider than the upper portion, the interval between the fusing seal portions 6 and 7 is The upper end portion is the narrowest, and if the upper end portion 1a of the front film 1 is picked and pulled, it can be easily started to tear, and can be smoothly torn downward as it is.

  When the left and right fusing seal portions 6 and 7 are torn in this way, the bag 3 opens larger than the left and right widths of the slope 4a of the triangular food 4 covered with the surface film 1 and exposes the entire slope 4a. It is also possible to take out the triangular food 4 easily.

  In addition, as shown in FIG. 4, the heat seal part 5 is good also as what was formed in the mountain shape where a top part is located in the approximate center of the width direction (left-right direction). In this case, the heat seal portion 5 has a single chevron shape, but since it is torn downward from the top to the left and right respectively, it can be opened with a relatively small force.

  The above is a preferred embodiment of the present invention, but the present invention is not limited to the configuration of the above-described embodiment, and can be implemented by appropriately changing the material, shape, dimensions, and the like.

It is explanatory drawing of the bag of the triangular food packaging body of embodiment of this invention. It is a perspective view of the triangular food packaging body of embodiment of this invention. It is a perspective view which shows a mode that the triangular food packaging body of embodiment of this invention is opened. It is a front view which shows the heat seal part vicinity of the triangular food packaging body of other embodiment of this invention.
