A packaging material for a sandwich described in Patent Document 1 or Patent Document 2 has an isosceles trapezoidal food container, and a right-angled sandwich is put in and wrapped therein. Then, the plane along the slope of the sandwich appears on the front of the package. Since a cut tape is provided on the front side, it is opened by pulling the cut tape, and the sandwich inside can be taken out from the opening.

However, the width that can be opened by the cut tape is limited, and it is impossible to simply take out a thick sandwich. So, although it is conceivable to provide a plurality of cut tapes in parallel, it is impossible to pull out such a cut tape at one time, and it is necessary to perform an opening operation several times in order to obtain a wide opening. In the sandwich packaging bag of Patent Document 2, a large number of heat seals are provided so as to cover the entire surface along the inclined side of the triangular sandwich, and furthermore, it is said that it can be opened widely and easily. However, the structure is complicated and the manufacturing time and cost are inevitably increased.

An object of the present invention is to provide a packaging bag that is large and can be easily opened and can easily take out a sandwich.

In order to solve the above problems, the sandwich packaging bag of the present invention has a body portion formed by overlapping a first sheet and a second sheet, which are two plastic sheets having an approximately isosceles trapezoid-shaped food container, and provided on the second sheet It has a cut-out portion and a third sheet, which is a plastic sheet, provided on top of the cut-out portion, and the cut-out portion is provided in the inside of a rectangle having an upper side as one side of an isosceles trapezoid, which is a food container, and the cut-out portion is one cutout parallel to the upper side. It is composed of an entry line and two cutting lines perpendicular to it. In addition, the third sheet has a cover portion connected to the second sheet so as to cover the cut-out portion, and a handle portion not connected to the second seat adjacent to the cover portion, and the second sheet and the third sheet are connected to the inside of the cut-out portion It is preferable that the inner connection portion, the non-connection portion where the second sheet and the third sheet are not connected along the cutout, and the outer connection portion in which the second sheet and the third sheet are connected outside the cutout are formed.

In the sandwich packaging bag of the present invention, by pulling off the third sheet, it is possible to obtain a large opening along the cutout portion, and it is possible to easily take out the sandwich inside.

Modes for carrying out the present invention will be described in detail based on the drawings. 1 is a front view showing a sandwich packaging bag, FIG. 2 is a right side view, FIG. 3 is a plan view, and FIG. 4 is a bottom view. Fig. 5 is an enlarged plan view, Fig. 6 is an enlarged bottom view, Fig. 7 is a sectional view A-A, Fig. 8 is a sectional view B-B, and Fig. 9 is an enlarged view of section C-C. The rear view appears the same as the front view, and the left view appears symmetrical with the right view.

A sandwich packaging bag (1) is formed by overlapping a first sheet (2) and a second sheet (3) having substantially the same outer appearance, and a third sheet (4) is attached on top of 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 the sandwich packaging bag 1 is entirely transparent unless printed.

The bag for sandwich packaging (1) has a food container (6) in the shape of an isosceles trapezoid with an upper side shorter than a lower side. In this food container 6, the first sheet 2 and the second sheet 3 are connected to the upper side 7 and the inclined side 8 of the side. Meanwhile, the first sheet 2 and the second sheet 3 are not connected to the lower side 9 . Therefore, the food container 6 has a bag shape with only the lower side 9 open, and sandwiches can be accommodated therein. Therefore, the shape of the food container 6 corresponds to the sandwich shape to be accommodated. A right-angled triangle sandwich is accommodated in this sandwich packaging bag, but the upper side 7 is almost the same as or slightly wider than the thickness of the sandwich, and the angle θ of the inclined side 8 to the vertical line is half the angle of the sandwich vertex. .

An ear part 10 is provided on the upper part of the food container 6, and a folding part 11 is provided on the lower part. Although there is no particular restriction on the ear portion 10 and the folding portion 11, here, they are cut out efficiently from a continuous sheet in a rectangular shape.

10 is a front view of a first sheet, FIG. 11 is a front view of a second sheet, and FIG. 12 is a front view of a third sheet. The first sheet and the second sheet have substantially the same shape, and have an isosceles trapezoidal portion forming a food containment portion, a rectangular portion forming an ear portion above it, and a rectangular portion forming a folding portion below it. . The body portion is formed by the first sheet and the second sheet. And, the second sheet has a cutout 12 is formed. This cutout 12 is provided in the central portion of the isosceles trapezoid, and is housed in the inside of a rectangle having, in particular, the upper side 7 of the isosceles trapezoid as one side. In addition, this cut part 12 is comprised by one cut line 12a parallel to the upper side 7, and two cut lines 12b perpendicular to this. In the cut-out portion and the cut-line in the present invention, the second sheet along the line is cut. Therefore, dotted lines or half cuts are not included. And, the cutting line 12a parallel to the upper side 7 is provided at a position close to the upper side 7, on the other hand, it is not provided at a portion close to the lower side. Therefore, it becomes a V-shaped incision with the lower side open, and the part surrounded by the inside is connected to the second sheet in the vicinity of the lower side. It is preferable to form this cutout 12 as large as possible, and it is wide enough to take out the sandwich accommodated inside.

The third seat 4 has a cover portion 13 for covering the cut-out portion 12 of the second seat 3 and a handle portion 14 provided thereon. The cover portion 13 is substantially rectangular and slightly wider than the cut-out portion 12 , that is, has a size large enough to form a connecting portion outside the cut-out portion 12 . And the handle part 14 is trapezoidal in this example.

The second sheet 3 and the third sheet 4 are connected by thermal fusion or the like. On the inside of the cut-out portion 12, the second sheet 3 and the third sheet 4 are connected to the inner connection portion 15 is provided. And, along the outside of the cut-out portion 12, the second sheet 3 and the third sheet 4 are not connected non-connection portion 16 is provided, and furthermore, on the outside of the cut-out portion 12, the first An outer connection portion 17 is formed to which the two sheets 3 and the third sheet 4 are connected. This outer connecting portion 17 is formed in a rectangular shape so as to surround the cut-out portion 12, thereby closing the periphery of the cut-out portion 12 and preventing air from entering or exiting through the cut-out portion 12. has been In addition, the handle part 14 on the upper part of the third seat 4 is not connected to the second seat 3.

Next, the first usage method of this sandwich packaging bag will be described. Since the bottom of the sandwich bag is open, insert the sandwich (x) into it. Insert from the side of the vertex of the right triangle of the sandwich (x) and insert it deep. At this time, the surface along the inclined side of the sandwich (x) is inserted in a direction exposed to the second sheet (3). Then, if the remaining portion of the lower part of the sandwich packaging bag is closed with a folding adhesive tape or seal like caramel folding, the packaging is completed. Fig. 13 is a perspective view showing a first state of use of the sandwich packaging bag.

A triangular sandwich is usually made by sandwiching a filling between two or more square or rectangular slices of bread, then cut in two along a diagonal line. In this way, a right-angled triangle sandwich is made. The plane along the slope becomes the cutting plane, and the sandwich ingredients are clearly visible on this plane. At the time of packaging, this cut surface appears at the position where the third sheet 4 is provided. And since the second sheet 3 and the third sheet 4 are transparent, the ingredients can be easily observed from the outside when the package is displayed in a store.

This sandwich packaging bag can be opened simply by holding the handle portion 14 with a finger and pulling the third sheet 4 from the second sheet 3. Since the second sheet 3 and the third sheet 4 are only connected by thermal fusion or the like, they can be easily pulled. And, since the inner portion of the cutout 12 of the second sheet 3 is connected to the third sheet 4 by the inner connecting portion 15, it is pulled out of the sandwich packaging bag together with the third sheet 4. . A large opening is thus obtained. It is possible to easily take out the sandwich inside from this opening.

A second method of using this sandwich packaging bag will be described. 14 is a perspective view showing a second state of use of the sandwich packaging bag. The sandwich (x) is inserted into the lower part of the sandwich packaging bag, but in this example, the sandwich (x) is inserted in a direction in which the vertical side is exposed to the second sheet (3). The packaging is completed by covering the remaining part of the lower part of the sandwich packaging bag with a folding adhesive tape or seal, such as caramel folding. It can be opened by holding the handle part 14 with a finger and pulling the third sheet 4 from the second sheet 3. In this example, the third sheet 4 may be smaller than that in the first use example, since it is sufficient to have a size sufficient to cover the vertical surface of the sandwich x. The sandwich (x) is taken out to the vertical plane side.
