Box-shaped containers are suitable for packaging rectangular sandwiches, but in recent years, rectangular sandwiches have become rare, and most sandwiches at convenience stores and the like are becoming right-angled triangle sandwiches. And box-like containers are not suitable for packaging triangular sandwiches.

The sandwich packaging materials made of the plastic sheets described in Patent Documents 1 to 3 have an isosceles trapezoidal food storage portion into which a right triangle sandwich is placed and packaged. It can be neatly wrapped along the shape of a right-angled triangle sandwich with almost no gaps. In addition, since an opening auxiliary member such as a cut tape is provided, it can be easily opened and the sandwich inside can be taken out from the opening. Furthermore, since it is made of a transparent plastic sheet, the inside of the sandwich can be easily observed.

However, plastic containers must be disposed of separately from combustibles after use. In addition, uncollected plastics flow out into the environment, becoming one of the causative substances of marine pollution, and adverse effects on ecosystems have also become a problem.

Fig. 3 is a perspective view showing the oblique side of the wrapped sandwich; Fig. 3 is a perspective view showing the vertical side of the packaged sandwich; FIG. 4 is a rear view showing another example of the sandwich packaging bag; FIG. 11 is a front view showing a second sheet of paper;

A mode 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 rear view thereof, FIG. 3 is a vertical cross-sectional view along AA of the same, and FIG. 4 is a cross-sectional view of the same BB. Although the paper sheet and the transparent sheet that constitute the sandwich packaging bag are thin sheets, the thickness is emphasized in FIGS. 3 and 4 to facilitate the understanding of the structure.

The main body of the sandwich packaging bag 1 is formed by superimposing a first paper sheet 2 and a second paper sheet 3 having substantially the same outer shape. Both the first paper sheet 2 and the second paper sheet 3 are thin paper sheets for food packaging. Here, the inward facing surfaces of the first paper sheet 2 and the second paper sheet 3 are each provided with a waterproof coating. Being a paper sheet, it is opaque.

The sandwich packaging bag 1 has a food storage portion 6 in the shape of an isosceles trapezoid whose upper side is shorter than its lower side. In this food storage portion 6, the first paper sheet 2 and the second paper sheet 3 are connected at the upper side 7 and the oblique side 8 of the side portion. On the other hand, the first paper sheet 2 and the second paper sheet 3 are not connected at the lower edge 9 . Therefore, the food storage portion 6 has a bag shape with only the lower side 9 open, and sandwiches can be stored therein. Therefore, the shape of the food container 6 corresponds to the shape of the sandwich to be contained. This sandwich packaging bag 1 accommodates a right-angled triangular sandwich, and the upper side 7 is approximately the same as or slightly wider than the thickness of the sandwich, and the angle θ of the oblique side 7 with respect to the vertical line is the angle 2θ of the vertex of the sandwich. is half of

Ear portions 10 are provided on the upper portion of the food storage portion 6, and folding portions 11 are provided on the lower portion. Although there are no particular restrictions on the ear portion 10 and the folded portion 11, they are rectangular here so that they can be efficiently cut out from the continuous sheet.

5 is a front view showing the first paper sheet, FIG. 6 is a front view showing the second paper sheet, and FIG. 7 is a front view showing the opening sheet. The first paper sheet 2 and the second paper sheet 3 have substantially the same shape, an isosceles trapezoidal portion forming the food storage portion 6, a rectangular portion forming the ears 10 above it, and a lower portion. It has a rectangular portion forming a fold 11 . The main body is formed by the first paper sheet and the second paper sheet.

A cut-out portion 14 is formed in the first paper sheet 2 . The cut-out portion 12 is provided in the central portion of the isosceles trapezoidal shape, and is particularly contained within a rectangle having the upper side 7 of the isosceles trapezoidal shape as one side. A transparent sheet 4 is attached to the cut-out portion 12 to form a window. The cut-out portion 12 may have a shape that occupies most of a rectangle whose side is the upper side 7 of the isosceles trapezoidal shape, or may be a part thereof. In this example, the cutout 12 has a width greater than 60% of the width of the rectangular portion, but a rectangular shape whose length is considerably less than the length of the rectangular portion. The cut-out portion may be circular, oblong oval, or the like, in addition to the rectangular shape, and may be provided in plurality. Since the inside of the sandwich can be observed through the window formed by the cutout 12, the width should be as wide as possible, preferably to the extent that the ingredients of the sandwich can be seen. In addition, the size of the transparent sheet 4 can be reduced by making it as small as possible. Alternatively, it may be as large as possible, covering substantially the entire surface along the hypotenuse of the sandwich.

The transparent sheet 4 is a transparent food packaging plastic film such as polypropylene or biodegradable plastic. Here, a transparent sheet 4 is attached to the surface of the first paper sheet 2 facing the second paper sheet 3 . Therefore, the transparent sheet 4 is provided inside the sandwich packaging bag 1 .

Preferably, the second paper sheet 3 is provided with an opening assisting member. In particular, it is preferable to provide an unsealing assisting member such as a cut tape or an unsealing sheet inside the rectangular portion having the upper side 7 of the isosceles trapezoidal shape as one side. In this example, a notch 14 is formed in the second paper sheet. The notch 14 is provided in the central portion of the isosceles trapezoidal shape, and particularly, is contained within a rectangle having the upper side 7 of the isosceles trapezoidal shape as one side. Furthermore, this cut portion 14 is formed in a U-shape by a horizontal cut line 15 provided horizontally near the upper side or near the lower side of the rectangular portion and a vertical cut line 16 provided vertically from both ends of the horizontal cut line 15. is configured to

Also, in this example, the second paper sheet is cut along the notch 14 . Therefore, in this example, the horizontal cut line 15, the vertical cut line 16, and the cut portion do not have perforations or half cuts. That is to say, it is a U-shaped notch that is open at the top, and the part enclosed therein is connected to the second paper sheet only near the top edge. The notch 14 is preferably made as large as possible and is wide enough to remove the sandwich contained therein.

The opening sheet 17 has a cover portion 18 for covering the cut portion 14 of the second paper sheet 3 and a grip portion 19 provided therebelow. Cover portion 18 is generally rectangular and is slightly wider than cut portion 14, ie large enough to form a connection outside cut portion 14. As shown in FIG. The knob portion 19 is trapezoidal in this example.

The second paper sheet 3 and the opening sheet 17 are connected by an adhesive or the like. Inside the notch 14, an inner connecting portion 20 is provided to which the second paper sheet 3 and the opening sheet 17 are connected. A non-connecting portion 21 where the second paper sheet 3 and the opening sheet 17 are not connected along the cut portion 14 is provided on the outer side thereof, and the second paper sheet 3 and An outer connecting portion 22 to which the opening sheet 17 is connected is formed. The outer connection part 22 is formed in a rectangular shape so as to surround the cut part 14, thereby closing the circumference of the cut part 14 and preventing air from entering or exiting through the cut part 14. - 特許庁. Also, the grip portion 19 at the bottom of the opening sheet 17 is not connected to the second paper sheet 3 .

Next, how to use this sandwich packaging bag will be explained. Since the lower part of the sandwich packaging bag 1 is open, the sandwich x is inserted from here. Insert from the vertex side of the right-angled triangle of sandwich x and insert it to the back. At this time, the sandwich x is placed in such an orientation that the surface along the oblique side of the sandwich x hits the first paper sheet 2 and the vertical surface hits the second paper sheet 3 . Then, the leftover portion of the lower portion of the sandwich packaging bag is folded like a caramel fold, and sealed with an adhesive tape or a seal to complete packaging with a high degree of airtightness. Figures 8 and 9 are perspective views of the packaged sandwich, showing how the sandwich packaging bag is used. Figure 8 shows the oblique side of the wrapped sandwich and Figure 9 shows the vertical side of the wrapped sandwich.

Triangular sandwiches are made by sandwiching the ingredients between two or more pieces of bread, usually square or rectangular, and then cut diagonally into two halves. In this way, a sandwich is created in which multiple right-angled triangles of bread are stacked on top of each other. The plane along the hypotenuse is the cut plane, and the ingredients sandwiched between the breads are observed. Furthermore, the ingredients can be observed better at the central portion than at the upper and lower ends of the slope. When the package is packaged, the opening support member appears on the vertical surface other than the cut surface, and in the case of this example, it is at the position where the notch 14 and the opening sheet 17 are provided. The notch 14 and the opening sheet 17 of the package are aligned with the vertical plane of the triangular sandwich, and the horizontal slit 16 and tab are aligned near the right angle of the triangular sandwich. The wrapped sandwich is displayed in the store with the side along the hypotenuse facing forward. In this way, by showing the ingredients of the sandwich to the consumer through the transparent sheet 4, it is possible to arouse the willingness to purchase the sandwich. Also, consumers can accurately select the sandwiches they want to eat by looking at the ingredients.

This sandwich packaging bag can be easily opened by pinching the tab portion 19 with fingers and peeling off the opening sheet 17 from the second paper sheet 3. - 特許庁Place the bottom of the sandwich on the palm of one hand and grab the sandwich with that hand. The opening sheet 17 is peeled off from the second paper sheet 3 by picking up the grip portion 19 with the fingers of the other hand and pulling it up. Since the second paper sheet 3 and the opening sheet 17 are only weakly connected with an adhesive or the like, they can be easily peeled off. Since the inner portion of the cut portion 14 of the second paper sheet 3 is connected to the opening sheet 17 by the inner connecting portion 20, the second paper sheet 3 is peeled off from the sandwich packaging bag together with the opening sheet 17.例文帳に追加A large aperture is thus obtained. During this time, the sandwich is grasped from below with one hand so that it does not fly out of the opening during opening. Then, the sandwich inside can be easily taken out from this opening. Although the ingredients of the sandwich cannot be seen from this opening side, the ingredients can be observed through the transparent sheet 4 of the first paper sheet 2. - 特許庁Even when a plurality of sandwiches contain different ingredients, the user can select the sandwich with the ingredients he/she wants to eat by looking at the transparent sheet 4.例文帳に追加

The tab 19 is at the bottom of the packaging sandwich and the connection with the second paper sheet 3 is open downwards. Therefore, even if some foreign matter falls on it during transportation or storage, it will not enter between the grip portion 19 and the second paper sheet 3 . Even if a foreign object blows up from below and enters temporarily, most of it falls naturally and does not remain. Foreign matter hardly sticks to the surface of the packaging bag, and the packaging bag is kept clean.

Although the knob portion 19 is provided downward in the above example, it can also be provided upward. FIG. 10 is a rear view showing another example of the sandwich packaging bag, and FIG. 11 is a front view showing another example of the second paper sheet 3. As shown in FIG. In this example, the horizontal cut line 16 is on the short side (upper side) side of the isosceles trapezoidal food storage portion 6, and the cut portion 14 has a downwardly open U-shape.

The opening sheet 17 may be the same as that shown in FIG. 7, but is attached to the second paper sheet 3 with the tab portion 19 facing upward. At this time, the inner connection portion 20 is provided along the shape of the cut portion 14 .

According to this alternative, the tabs 19 do not project below the wrapped sandwich, but appear on the sides of the ears 10 . When opening the package, grasp the side of the sandwich x with one hand, grasp the knob portion 19 with the other hand, and pull it downward. The opening sheet 17 can thus be pulled away from the second paper sheet 3 to form an opening through which the sandwich x is removed.

Also, in this example as well as in the example shown in FIG. 2, an adhesiveness reducing treatment portion is provided along the notched portion of the second paper sheet, and the opening sheet is opened and resealed with a low-adhesive adhesive. It may possibly be adhered to a second paper sheet. For example, by applying a treatment such as OP agent coating to the area of the outer bonding portion of the second paper sheet 3, the surface can be smoothed and the adhesiveness can be reduced. As a result, the fibers and the like of the second paper sheet 3 are not torn off when unsealing, and the surfaces of the second paper sheet 3 and the opening sheet 17 are maintained in a smooth state, and are reconnected by the adhesive remaining at the connecting portion. be able to. When the entire sandwich cannot be eaten, the unsealing sheet 17 can be reattached to the second paper sheet 3, and a good sealed state can be reproduced. can continue.
