Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rice ball packaging sheet in which sheet-like food such as seaweed is sandwiched between a plurality of films, and a packaged rice ball packaged with the packaging sheet.

[0002]

[Prior art]

 As such a wrapping sheet, a rectangular wrapping sheet (7) shown in FIGS. 4 and 5 has been previously proposed (Jitsuko 63-40152). The packaging sheet (7) has a sheet-shaped food product (8) sandwiched between two films, an outer film (1) and an inner film (2), and the outer film (1) has a central portion in the width direction. One perforation (91) is provided over the entire length in the longitudinal direction, and the inner film (2) has two film pieces (21) (21) facing each other at approximately the center in the width direction of the packaging sheet. The outer film (1) and the inner film (2) are formed by overlapping sides, and both longitudinal edges of the outer film (1) and the inner film (2) are heat-welded.

As shown in FIG. 5, the packaging sheet (7) has one side of the triangular rice ball rice (4) placed on the inner surface of the sheet at approximately the center in the longitudinal direction, and the sheet is formed on both sides of the triangular rice ball rice (4). Cover.

The overlapping ears (71) (71) of the sheets are folded back to the back surface of the triangular rice ball rice (4), and as shown in FIG. 7, a seal piece (70) is provided between the folded back ears (71) (71). Stop with.

Since the inner film (2) is interposed between the rice ball rice (4) and the sheet food product (3), the sheet food product (8) does not contact the rice ball food (4) and The moisture of the sheet prevents the sheet food from getting damp.

When eating rice ball (4), the seal piece (70) is peeled off and the end portion (13) of the outer film (1) is pulled outward as indicated by the arrow. Since the outer film (1) is provided with perforations (91) at the center thereof, the outer film (1) is separated from the perforations to the left and right.

When the outer film (1) is divided into left and right parts, the respective film pieces (21) (21) of the inner film (2) joined to the outer film (1) are separated from each other. ), It is pulled out from between the sheet-shaped food (8) and the rice ball rice (4) and separated from the rice ball rice (4), whereby the sheet food (8) becomes rice ball ( It is said that 4) is directly covered.

[0008]

[Problems to be solved by the device]

 However, the rice ball wrapped with the above packaging film must first peel off the seal piece (70), and if the seal piece (70) is peeled off, the packaging will be unmelted and the next film drawing operation will not work well. .

At the top of the triangular rice ball where the perforations (91) of the outer film (1) are located, the film is piled up and the rice balls are tightened, and the pulling resistance of the film becomes large and smooth. There is a risk that the rice ball may not be pulled out and the rice ball may be cracked at the center due to excessive force.

In particular, a rice ball with an ingredient such as umeboshi in the center part is easily cracked at the center part, and therefore most of the onigiri parts are cracked when the film is drawn out. Also, even if the film does not crack at the center of the rice ball, when the film is pulled outward as described above, the film is centered around the top of the rice ball with a large drawing resistance, as shown by arrow A in FIG. The force acts in an arc shape, and at that time, there is a problem that the bottom end of the rice ball is caught by the film and cracks.

Further, there is a problem that outside air penetrates through the perforations (91) of the outer film (1) to moisten the sheet-shaped food product. As described above, the conventional packaging film has many problems and has not been put into practical use. The present invention clarifies a packaging film and a rice ball packaged with the packaging film, which can solve the above problems all at once.

[0012]

[Means for solving the problem]

 The packaging sheet of the present invention has an intermediate film (3) disposed between the outer film (1) and the inner film (2), and the sheet-shaped food (8) is provided between the intermediate film (3) and the inner film (2). ), The intermediate film (3) and the inner film (2) are rectangular film pieces (31) (31), (21) (21) in the width direction of the packaging sheet. The outer film (1) has two perforations (91) (91) along the entire length in the longitudinal direction of the packaging sheet, and the perforations (91) (91) are made to face each other at the center. A strip-shaped portion (9) for separation is formed in the middle of the packaging sheet in the widthwise direction, and the outer peripheral portion of the film excluding both ends of the strip-shaped portion is heat-welded in three layers.

In the rice balls wrapped with the above packaging sheet, the intermediate film (3) and the inner film (2) are rectangular film pieces (31), (31), (21) and (21) in the width direction of the packaging sheet. The outer film (1) is provided with two perforations (91) (91) over the entire length in the longitudinal direction of the packaging sheet, and the outer film (1) is perforated (91) (91). ), A strip-shaped portion (9) for separation is formed at a substantially central portion in the width direction of the packaging sheet, and the outer peripheral portion of the film excluding both ends of the strip-shaped portion is heat-welded in three layers, The base of the triangular rice ball rice (4) is oriented in the width direction of the film approximately above the center of the inner film (2) in the longitudinal direction, and the strip-shaped portion (9) for separating the outer film is the triangular rice ball rice (4). It is wrapped from the top toward the center of the opposite side, and the ears (71) at the four corners of the wrapping sheet are folded back on top of the back of the rice ball, and the folded ears (7 1) is joined to the outside of the separating strip (9) of the outer film (1).

[0014]

[Action and effect]

 Since the perforations (91) of the outer film (1) are closed from the inside by the intermediate film (3), outside air is prevented from entering the film through the intermittent slits of the perforations (91), and the sheet It is possible to prevent the food product from getting damp as much as possible.

In addition, when eating the packaging rice ball, it is not necessary to peel off the seal piece (70) that joins the folded back ears (71) of the packaging sheet (7) as in the conventional case, and the next opening operation can be performed smoothly. You can go to

From the top of the rice ball, take the tip of the strip (9) for separating the outer film (1), pull it to the bottom side of the rice ball, rotate it from the bottom to the back side of the rice ball, and pull it to the top side to pull the strip. Separate (9).

Next, the bottom end (13) of the rice ball is pulled outward. As described above, the outer film (1) is stripped off in the central portion in the width direction over the entire length in the longitudinal direction, and the number of overlapping outer films is reduced at the top of the rice ball. The pull-out resistance of the film is small, and the film can be pulled out smoothly without cracking the rice ball.

Further, by peeling the outer film (1) substantially in the widthwise central portion into a strip shape, the film can be drawn out substantially right next to the outer edge of the rice ball. It is possible to prevent scratching and cracking.
