Description

This invention relates to a packaging bag for packaging foods such as rice balls.

BACKGROUND ART As a packaging material for foods such as rice balls, a bag is used which is formed by stacking two sheets one on top of the other, leaving a portion of the periphery unconnected to form an opening, and connecting the other portions.

Patent Document 1 discloses that the bag is made by heat-sealing a front sheet made of a uniaxially stretched film and a back sheet made of a strong biaxially stretched film, the peripheral edges of which are heat-sealed except for the upper side. The backing sheet is made of 200% polyester, which increases the bonding strength of the fused peripheral edges of the front and back sheets, and when the rice balls are stored inside, the upper half of the main body of the bag is folded and automatically packaged, the opening form of the main body of the bag is It is described that folding and packaging can be carried out reliably and efficiently by holding with a strong backing sheet.

Cited Document 2 discloses that two packaging films are polymerized, their peripheral edges are joined together, a rice ball storage chamber is formed between both packaging films, and a protrusion is integrally provided on each packaging film. , it is described that the peripheral edges of both protrusions are joined except for the tips, and that the protrusions constitute an opening means.

Cited document 3 discloses a bag body having an opening on the wide edge side by overlapping trapezoidal front and back films and heat-sealing the narrow edge portion and both inclined edge portions in a removable manner. A pair of opening protrusions extend from the narrow end piece, and the upper end of the backing film extends from the opening end to form a sealing piece wider than the bag body. When folded over the front film and attached with the adhesive layer, both ends of the sealing piece protrude outward from both sloped edges of the bag body and are folded onto both sloped edges of the bag body. It is described that it is formed at the sealed end.

Cited Document 4 describes a packaging bag for rice balls. In the approximately isosceles trapezoidal sheet, a sheet that overlaps on the opening side and a sheet that overlaps on the opposite side of the opening are connected along the sides of the approximately isosceles trapezoidal sheet. The package is opened by pinching the central part of the sheet that overlaps on the opposite side of the sheet and pulling up the part indicated by the words "pull upwards" and the triangular shape near it.

In the invention of Patent Document 1, in order to expose the rice balls packaged by the bag main body and eat them, the upper and lower parts of the tabs protruding from one side edge of the lower half of the bag main body are connected to each other. By pulling in the direction of separation, the straight stripes for tearing provided on the backing sheet are torn from the notches formed in the tabs. Here, in order to tear along the straight stripes for tearing, the front sheet and the back sheet must be torn at the same time, which requires strong force. Moreover, since the front sheet and the back sheet are in contact with the highly adhesive surface of the rice ball, resistance is generated that prevents the sheets from moving on the surface of the rice ball.

In the inventions of Patent Document 2 and Patent Document 3, the seal is opened by peeling off two connected sheets. A starting point for peeling is provided in the center on the opposite side of the opening, and opening is started from here. Peeling of the two sheets begins from the center and progresses to the left and right sides. That is, it is necessary to pull with a strong force in order to cause the peeling to proceed at two locations simultaneously. Furthermore, as the unpacking progresses, the area where the sheet is pinched with one's fingers and the area where peeling progresses become farther apart, making it difficult for the force applied by pulling to separate the two sheets. Furthermore, since the sheet is grabbed and pulled with each hand, it is impossible to hold the rice ball, and there is a possibility that the rice ball may fall when the package is opened.

In the rice ball packaging bag of Patent Document 4, the bag is opened by pinching a designated area near the front center of the packaged rice ball and pulling upward to peel off the sheet provided on the opposite side of the opening. In this case as well, strong force is required because the joints on both sides of the sheet are torn off at the same time.

The purpose of this invention is to provide a food packaging bag that can be easily opened without requiring strong force.

In order to solve the above-mentioned problems, the food packaging bag of this invention has a second sheet, a third sheet, which is a front sheet, and a first sheet, which is a back sheet, which are overlapped, and a connection part and an opening are formed in the periphery. The second sheet is provided on the opening side, a first connecting portion connected to the first sheet is formed along both sides of the second sheet, and a third sheet is partially connected to the first sheet. A second connecting portion is formed on the side facing the opening while overlapping the two sheets, and is easily connected to the third sheet and the first sheet along the periphery of the first sheet, At least one of both ends of the second connection part is provided with an unsealing start part display indicating that it is an unsealing start part. The opening start section display may be provided at both ends of the second connection section.

Furthermore, the packaged rice ball of this invention is a rice ball packaged in the above-mentioned food packaging bag, and the opening side of the food packaging bag is folded and sealed so that the fold does not extend to the opening start part display. .

The food packaging bag of this invention has an opening start part set at the end of the connection part, and the separation of the sheets at the connection part proceeds at one point, so it can be opened easily without applying strong force. I can do it.

It is a front view showing a food packaging bag. It is a rear view of the same. It is a left side view of the same. FIG. 3 is a front view showing the first sheet. It is a front view which shows a 2nd sheet|seat. FIG. 7 is a front view showing the third sheet. FIG. 3 is a front view schematically showing a bending line. It is a front view showing a packaged rice ball. It is a rear view of the same.

A form for implementing the present invention will be described in detail based on the drawings. FIG. 1 is a front view of a food packaging bag, FIG. 2 is a rear view thereof, and FIG. 3 is a left side view thereof. Although the members constituting this food packaging bag are thin sheets, the thickness is emphasized in FIG. 3 to make the structure easier to understand.

The front sheets 3 and 4 and the back sheet 2 are stacked, and a part of the periphery is an opening that is not connected to each other, and the other peripheral area is a bag body where the front sheet and the back sheet are connected. It has become. Here, one first sheet 2 is a back sheet, and a front sheet is a combination of a second sheet 3 and a third sheet 4.

FIG. 4 is a front view of the first seat, FIG. 5 is a front view of the second seat, and FIG. 6 is a front view of the third seat. These sheets are fine as long as they can safely store food. For example, if it is a paper sheet, it is preferable to use a sheet that is laminated on at least one side and can be heat-sealed. In this example, a transparent plastic film is used that is heat sealable.

The first sheet 2 has a side article accommodating portion 5 having a generally isosceles trapezoidal shape as its main part, and is narrow at the upper side where it is connected to the third sheet 4 and widens toward the lower long side where it becomes the opening 6. It has a wide shape. The upper portion may be rounded near both end portions as shown in FIG. Alternatively, the upper part may be formed of a continuous curve without a straight part. Further, in this example, a folding area 7 is provided following the long side 6.

The second sheet 3 overlaps the lower portion of the first sheet 2 and the opening 6 side. In this example, it has an isosceles trapezoid shape, with both sides overlapping the sides 8 of the isosceles trapezoid on the first sheet, and the lower side overlapping the lower side (long side 6) of the isosceles trapezoid on the first sheet. . A first connecting portion 9 is formed along both sides 8, in which the first sheet 2 and the second sheet 3 are connected. On the other hand, the lower part is not connected and forms an opening 6. Further, the upper side of the second sheet 3 is not connected to the first sheet 2.

The third sheet 4 overlaps the upper part of the first sheet 2, that is, the side facing the opening 6. Both sides 8 overlap the side sides 8 of the substantially isosceles trapezoid 5 of the first sheet 2, and the upper part overlaps the upper part of the first sheet 2. The lower part does not extend to the long side 6 of the isosceles trapezoid 5 of the first sheet 2.

A back sheet is formed by the combination of the second sheet 3 and the third sheet 4, and has the same shape as the food storage section 5 of the first sheet 2, but the second sheet 3 and the third sheet 4 overlap near the boundary. There is an overlapping area. Here, the third sheet 4 is in contact with the upper surface of the second sheet 3, that is, the surface opposite to the surface in contact with the first sheet 2. In the center of this region, the second sheet 3 and the third sheet 4 are not connected or are weakly connected. Here, the third connecting part 11 is formed with a weaker connection than the first connecting part 9 and the second connecting part 10, but the vicinity of the lower end of the third sheet 4 is not connected, and the second sheet 3 and the second connecting part 10 are not connected. 3. It is possible to insert a finger between the sheets 4.

Both sides of the overlapping area of the second sheet 3 and the third sheet 4 have an easy-to-open connection, which means that they will not peel off due to external force unexpectedly applied during packaging work or movement, but will not peel off when trying to open the package. The second connection portion 10 is formed with a connection that can be easily peeled off. Such an easy-to-open connection is also called an easy-peel connection and is already in widespread use.

Also in the overlapped portion of the first sheet 3 and the third sheet 4, a second connecting portion 10 is formed along the periphery thereof by an easily openable connection. The second connecting portion 10 is formed like a single band along the outer periphery from one side edge 12a to the other side edge 12b of the second sheet 3. An unsealing start section display 13 is provided on at least one of both ends 12a and 12b of the second connecting section 10 to indicate that it is an unsealing start section. For example, a small triangle or the like is displayed at the end 12 of the second connecting portion 10, and an arrow pointing from there toward the upper side is further displayed. This allows the consumer to be shown where they should pinch the bag when opening it and in which direction to pull it up.

The first connecting portion 9 and the second connecting portion 10 can be formed by, for example, fusing, heat sealing, or the like.

Next, a food packaging method will be explained. The food packaging bag 1 is a bag body having connection parts 9, 10 and an opening 6 formed along its periphery. Open the opening 6 and put the food x in there. The opening 6 side of the food packaging bag 1 is folded so that the crease does not extend to the opening start part display 13, and the end of the folded part is sealed with adhesive tape, a seal, or the like.

Various foods can be selected as the food to be packaged, such as disc-shaped or triangular rice balls, cooked bread, sweet bread, and side dishes. Here, an example of packaging triangular rice balls will be explained. FIG. 7 is a front view schematically showing the bending line.

In FIG. 7, the front sheet composed of the second sheet 3 and the third sheet 4 is shown facing forward. Insert the triangular rice ball x with the vertex facing the opening 6, that is, toward the upper side in FIG. Then, it is folded in the back direction along the first fold line 14 and the second fold line 15. The first fold line and the second fold line each extend from directly below the end of the second connecting portion toward the center of the lower end of the first sheet. Then, fold the triangular rice ball x toward the back side along the third fold line 16 along the bottom side. The folded sheet end overlaps with the back side, and an adhesive tape or a sticker 17 is pasted thereon to fix it. In this way, the bag is sealed and the packaged rice ball 20 is obtained.

FIG. 8 is a front view of the packaged rice ball, and FIG. 9 is a rear view thereof. In the front view, the end portions 12 of the second connecting portion 10 are exposed on both sides of the lower portion. An unsealing start part display 13 is displayed on one or both of the ends 12.

The opening of the packaged rice ball 20 will be explained. Hold the rice ball x with one hand, and pinch near the end 12 of the second connection part 10 with the other hand and pull it up. In this example, since the opening start part display 13 is provided at both ends 12a and 12b, the package can be opened from either side. For example, if you are right-handed, pick up the rice ball x with your left hand, pick the opening start section display 13 on the left side with your right hand, and pull it up. The opposite is true for left-handed people.

Since the opening start section display 13 indicates the position where the bag should be pinched and the direction in which it should be pulled up, the consumer can open the bag according to the instructions without any special instructions.

Since the opening start part display 13 is located near the end 12 of the second connection part 10 which is the opening start position, the pulling force acts directly on the opening start position and the peeling starts from the end 12 of the second connection part 10. starts. Starting from there, the peeling progresses along the second connecting portion 10 toward the other end 12b. At this point, no peeling occurs yet on the other end 12b side. Therefore, since the peeling progresses in one place, all the lifting force is concentrated in this one place. Thereby, the second connecting portion 10 can be easily peeled off without pulling with strong force. When the peeling progresses to near the other end 12b, a large opening is formed, the upper part of the rice ball is exposed, and the rice ball x can be eaten. The third sheet can be peeled off with one hand, and the package can be opened in one operation without changing hands. During this time, the rice ball x is firmly held in one hand, so there is no risk that the rice ball will fall during opening.
