  In the above-mentioned packaging rice ball, the sealing part (7) of the packaging bag (1) overlaps the inner ends of the film pieces (41) and (42) of the inner film (4) located at the center of the bag opening (13). Since it is formed by welding except the portion, the central portion of the bag opening (13) remains open even after sealing. This moistens the sheet-like food and causes problems such as contamination by foreign matter and inflow of outside air, resulting in unsanitary conditions.

When the bag opening (13) is sealed over its entire length, the outer film (3) is cut off well because the welding for sealing becomes an obstacle at the start of the cutting of the severable part (31) of the outer film (3). If the four overlapping parts of the inner ends of the film pieces (41) and (42) of the inner film (4) are welded, and the bag is finally divided into two left and right, the welded part will The rice balls need to be shredded, and the rice balls falling slipped, causing the rice balls to fall out of shape or become dirty, making them impossible to eat.
This invention clarifies the packaged rice lump which solved the said problem.

The packaged rice lump according to claim 1 is a packaged rice lump in which the rice lump (6) is accommodated in the packaging bag (1), and the sheet body (2) forming the packaging bag (1) has an outer film (3). The inner and outer films (4) and (3) are sandwiched between the inner and outer films (4) and the inner and outer films (4) and (3). Consisting of
The outer film (3) has a section (31) that can be divided over the entire length in the longitudinal direction at the center in the width direction, and the inner film (4) is one of the two film pieces (41) (42). The overlapping portions (43) overlap the severable portion (31) of the outer film (3).
After placing the rice cake (6) on the longitudinal center of the sheet body (2) on the inner film (4), both ends in the longitudinal direction of the sheet body (2) are the same across the rice cake (6). Fold it to face the direction,
The side edge portions on both sides of the sheet body (2) are folded and the overlapping portions are welded to form the collar portion (12), and the packaging bag (2) is open at both ends in the longitudinal direction. 1),
After the bag opening (13) side of both collar parts (12) (12) is folded inward, the sealing part (7) is formed by welding over the entire length of the bag opening (13),

The weakly welded portion (71) is applied to both ends of the weakly welded portion (71) , and is applied corresponding to the portion other than the weakly welded portion (71) , and the strongly welded portion (72) (72) that does not easily peel off even when pulled .
Consists of.

  Claim 2 is the packaged rice lump according to claim 1, wherein the rice lump (6) is in the shape of a round bar and is housed in a collapsed state in the bag so as to be parallel to the sealing part () of the packaging bag, The sheet body (2) constituting the packaging bag is folded in a U-shape with two corners so as to sandwich the lump of rice (6) at the bottom of the packaging bag.

In the packaged rice lump of claim 1, since the bag opening (13) is welded and sealed over the entire length, it is possible to prevent the inflow of outside air and the mixing of foreign substances, thereby preventing the moisture of the sheet-like food, It can be protected hygienically.
In addition, the welded seal at the bag opening is weakly welded in the vicinity of the splitting start end of the outer film (3), so there is no hindrance to the splitting of the outer film, and four pieces of the inner film are overlapped. Since the welding of the film is weak, when the outer film (3) is divided and the bag is divided into left and right parts, the welding of the overlapping part (43) of the film pieces (41) (42) is also easily peeled off and is clean. You can make a bag for 2 minutes.

  In addition to the effect of claim 1, the packaged rice lump of claim 2 is not stable as the bottom of the packaging bag (1) is like a round bar-shaped rice lump (6) with the contents in the bag lying sideways. Even if it exists, it can be stored well and can be displayed stably when displaying the packaged food.

FIG. 4 shows a procedure in which the rice cake (6) is placed on the sheet body (2) and the packaging bag is formed while wrapping the rice cake (6) with the sheet body (2).
As shown in FIG. 4a, the rice chunk (6) of the example has a short round bar shape with a diameter of about 4 cm and a length of about 10 cm.

  As shown in FIG. 3, the sheet body (2) is formed by sandwiching a rectangular sheet-like food (5) between the transparent outer film (3) and the transparent inner film (4).

  The outer film (3) has a length of about 20 cm and a width of about 16 cm. The length is about 5 times the diameter of the rice chunks (6) and (6), and the width and length are the same as those of the rice chunks (6). The length is about 1.5 times the diameter of the lump (6).

The outer film (3) has a separable portion (31) that can split the film in the length direction over the entire length at the center in the width direction.
The severable portion (31) of the example is a directional film in which the outer film (3) is easily torn in the longitudinal direction, and two cuts ( 32 ) ( 32 ) are provided at the center of the end of the film. It is configured by applying.
In the embodiment, the interval between the cuts ( 32 ) ( 32 ) is 1.5 cm.

  The inner film (4) has a size that overlaps with the outer film (3) so that the contours coincide with each other, and the two rectangular film pieces (41) and (42) having the same shape are connected to the inner edge along the longitudinal direction of each other. Are overlapped with an overlap width of about 1.5 cm.

In the embodiment, the sheet-like food (5) is a sheet-like seaweed (5a).
The sheet-like seaweed (5a) has a length of about 14 cm and a width of about 10 cm. The length is slightly more than three times the diameter of the rice cake (6), that is, a little more than one round on the outer circumference of the rice cake (6). The winding length and the width are about the same as the length of the rice chunk (6).

As shown in FIGS. 1 and 2, the sheet body (2) has a sheet-like seaweed (5a) between the outer film (3) and the inner film (4). ) And (3) are aligned and centered, and are formed by welding the inner and outer films (4) and (3) linearly so as to surround the sheet-like seaweed (5a). The
The welds (22) and (22) extending along the short side of the sheet body (2) are divided into two film pieces (41) and (42) of the separable portion (31) of the outer film (3) and the inner film (4). ) Is not hung on the overlapping portion (43).

  As shown in FIG. 4a, the rice lump (6) is placed on the inner film (4) of the sheet body (2) in a tilted state. At this time, the rice lump (6) is located at the center of the length of the sheet body (2) and faces in the width direction of the sheet body (2), and the center of the length of the rice lump (6) is the width center of the sheet body. Place it so that it is roughly aligned. In this state, both ends of the rice lump (6) do not protrude from both ends in the width direction of the sheet-like laver (5a) in the sheet body (2).

  As shown in FIG. 4b, the sheet body (2) is folded on the peripheral surface of the rice lump (6) so that both end edges in the length direction of the sheet body (2) are aligned. At this time, the sheet body (2) is not folded into a rounded U shape along the circumferential surface of the rice lump (6), but at two points with a spacing W corresponding to the diameter of the lump (6). It is folded into a U shape having square portions (21) and (21) at substantially right angles.

Next, as shown in FIG. 4c, both side edges along the longitudinal direction of the sheet body (2) are folded on the end face of the rice lump (6) and stopped by welding (11) to form the collar portion (12). .
Thereby, the packaging bag (1) in which both ends of the sheet body (2) are opened (13) is formed.

  Finally, as shown in FIG. 4d, the bag opening (13) side of the heel part (12) on both sides of the packaging bag (1) is folded inward, and the bag opening (13) is closed by high frequency welding, heat welding or the like. A sealing portion (7) is formed.

The sealing portion (7) is not welded with a uniform welding strength over the entire length of the bag opening (13), but the film piece (4) of the inner film (4) of the sealing portion (7). 41) In the range of the overlapping part (43) between the inner ends of (42), it is applied corresponding to the weakly welded part (71) weakly welded to the extent that it can be easily peeled off by hand and the other parts. It consists of strong welds (72) and (72) that do not peel easily even when pulled.
In the sealing part (11), there is no room for outside air or foreign matter to enter the bag.

  In the case of the example, the sealing portion (11) is welded in two stages. First, weak welding is applied in a thin line within a range slightly exceeding the range of the overlapping portion (43) between the inner ends of the film pieces (41) and (42) of the inner film (4), and then, at both ends of the weak welding line. A thick line is strongly welded so that it does not hook on the overlapping part of the four pieces of the inner ends of the film pieces (41) and (42). The welding procedure may be reversed.

To unwrap the packaged rice cake (6), with one hand, lightly grab the rice cake (6) from one side of the packaging bag (1) around the separable part (31). Hold. With the other hand, the separation start end (31a) of the separable portion (31) is picked and pulled to the other end side along the longitudinal direction of the separable portion (31). As shown in FIG. 6, the severable portion (31) is separated from the packaging bag (1) in a band shape, and the outer film (3) is divided into two.
At this time, the four overlapping portions of the inner ends of the film pieces (41) and (42) of the inner film (4) are welded, and the separable portion (31) of the outer film (3) is the weakly welded portion ( 71 ). When it passes and is divided, it may peel off by the impact, but it may not peel off. Even if it is not peeled off, by pulling the half of the divided outer film (3) and the inner film piece together, the weakly welded portion (71 ) Easily peels off.
As a result, half of the sheet-like seaweed (5a) is exposed.

Hold the rice cake (6) from above the exposed sheet-like seaweed (5a) with the hand that pulled one side of the packaging bag (1), and pick the other half of the packaging bag with the other hand and pull it outward. .
The packaging bag (1) is completely removed from the packaged rice cake, leaving the rice cake (6) and the sheet-like seaweed (5a), and the sheet-like seaweed (5a) directly covers the rice cake (6).
You can eat the rice cake (6) covered with fresh sheet-like seaweed (5a).
