The 9 series shows an enlarged view of the CC portion of the bag for sandwich packaging. The rear view is presented the same as the front view, and the left view is presented symmetrically with the right view.

The sandwich packaging bag 1 is formed by laminating a first sheet 2 and a second sheet 3 having substantially the same outer shape, and a third sheet 4 is mounted on the second sheet 3. The first sheet 2, the second sheet 3, and the third sheet 4 are all thin and transparent plastic films, and as long as the sandwich packaging bag 1 is not printed, the whole is transparent.

The sandwich packaging bag 1 has an isosceles trapezoid-shaped food container 6 having an upper side shorter than a lower side. In the food storage portion 6, the first sheet 2 and the second sheet 3 are connected to the upper side 7 and the hypotenuse 8 on the side. On the other hand, in the lower side 9, the first sheet 2 and the second sheet 3 are not connected. Therefore, the food container 6 has a bag shape with only the lower side 9 open, and can hold sandwiches inside. Therefore, the shape of the food storage portion 6 corresponds to the shape of the sandwiches to be stored. Although a sandwich of a right-angled triangle is contained in the sandwich packaging bag, the top 7 is approximately the same thickness or slightly wider than the sandwich, and the angle θ with respect to the vertical line of the hypotenuse 8 is the angle of the apex of the sandwich half.

An ear portion 10 is provided on the upper portion of the food storage portion 6, and a folded portion 11 is provided on the lower portion. The ear portion 10 and the folded portion 11 are not particularly limited. Here, the ear portion 10 is formed in a rectangular shape and is efficiently cut out from a continuous sheet.

FIG. 10 shows a front view of the first piece, FIG. 11 shows a front view of the second piece, and FIG. 12 shows a front view of the third piece. The first sheet and the second sheet are substantially the same shape and have: an isosceles ladder-shaped portion to form a food storage portion; a rectangular portion to form an ear portion above the isosceles-shaped portion; and a rectangular shape The part is a folded portion below the isosceles ladder-shaped part. A body portion is formed by the first sheet and the second sheet. A cutout portion 12 is formed in the second sheet. The cutout portion 12 is provided at the central portion of the isosceles ladder shape, and is particularly housed in a rectangular interior having the isosceles ladder-shaped upper side 7 as one side. It should be noted that the cutout portion 12 is constituted by a cutout line 12a parallel to the upper side 7 and two cutout lines 12b perpendicular to the cutout line 12a. In the present invention, in the cutout portion and the cutout line, the second sheet is cut along the line. Therefore, perforation and half cut are not included. The cut line 12a parallel to the upper side 7 is provided near the upper side 7 and is not provided near the lower side. Therefore, a sloping incision that is open on the lower side is formed, and the portion surrounded by it is connected to the second piece near the lower side. The cutout portion 12 is preferably formed as large as possible, and has a sufficient width so as to be able to take out the sandwiches stored therein.

The third sheet 4 has: a covering portion 13 for covering the second sheet 3 The notch portion 12 and the grasping portion 14 are provided above the covering portion 13. The covering portion 13 is substantially rectangular, and is slightly wider than the cutout portion 12, that is, has a size capable of forming a connection portion on the outside of the cutout portion 12. The gripping portion 14 is trapezoidal in this example.

The second sheet 3 and the third sheet 4 are connected by thermal fusion or the like. An inner connecting portion 15 is provided on the inner side of the cutout portion 12. The inner connecting portion 15 is connected to the second sheet 3 and the third sheet 4. In addition, a non-connecting portion 16 is provided on the outside of the cutout portion 12, and the non-connecting portion 16 is not connected to the second sheet 3 and the third sheet 4 along the cutout portion 12; There is an outer connecting portion 17 which connects the second sheet 3 and the third sheet 4. The outer connecting portion 17 is formed in a rectangular shape so as to surround the cutout portion 12, so that the periphery of the cutout portion 12 is closed, and air cannot pass through the cutout portion 12. In addition, the upper grip portion 14 of the third sheet 4 is not connected to the second sheet 3.

Next, a first method of using the bag for sandwich packaging will be described. Since the lower part of the bag for sandwich packing is open, sandwich x is inserted from here. Insert from the vertex side of the right triangle of sandwich x, and enter the interior. At this time, the surface along the hypotenuse of the sandwich x enters in a direction abutting the second sheet 3. Next, the excess portion of the lower portion of the sandwich packaging bag is folded at an angle, and fixed with an adhesive tape or a seal to complete the packaging. FIG. 13 is a perspective view showing a first use state of the bag for sandwich packaging.

Triangular sandwiches are usually made by sandwiching ingredients between two or more square or rectangular pieces of bread and cutting them into two along a diagonal. In this way, a right-angled triangle sandwich is made. The surface along the hypotenuse is the cut surface, and the material of the sandwich can be clearly seen in this surface. At the time of packaging, this cut surface appears at the position where the third sheet 4 is provided. In addition, since the second sheet 3 and the third sheet 4 are transparent, the materials can be clearly observed from the outside when the package is displayed in a store.

This sandwich packaging bag can be easily opened by grasping the grasping portion 14 with a finger and peeling the third sheet 4 from the second sheet 3. Since the second sheet 3 and the third sheet 4 are connected only by thermal fusion or the like, they can be easily peeled off. In addition, since the inner portion of the cutout portion 12 of the second sheet 3 is connected to the third sheet 4 by the inner connecting portion 15, it is peeled from the sandwich packaging bag together with the third sheet 4. In this way, a large opening can be obtained. The inner sandwich can be easily taken out from this opening.

A second method of using the bag for sandwich packaging will be described. Fig. 14 is a perspective view showing a second use state of the bag for sandwich packaging. Although the sandwich x is inserted from the lower portion of the sandwich packaging bag, in this example, the vertical surface of the sandwich x enters in a direction abutting the second sheet 3. The excess portion of the lower portion of the sandwich packaging bag is folded in a folded manner, and fixed with an adhesive tape or a seal to complete the packaging. It is possible to open the seal by grasping the grasping portion 14 with a finger and peeling the third sheet 4 from the second sheet 3. In this example, since the The three pieces 4 need only have a sufficient size to cover the vertical surface of the sandwich x, and are smaller than the first use example. The sandwich x is taken out from the vertical surface side.
