Description

  The present invention is configured to be able to be packaged in a state in which a sheet-like food such as sheet-like seaweed and a cooked rice processed food such as a triangular rice ball are separated from each other. The present invention relates to a packaged food for cooked rice food that can be combined and eaten.

  Rice balls sold at convenience stores and the like are packaged by a packaging material containing sheet-like seaweed between an outer sheet and an inner sheet. Specifically, the packaging material includes an outer sheet that can be divided in one direction and an inner sheet that can be divided in the same direction as the outer sheet. There is known one formed by sealing an outer film and an inner film so as to surround the seaweed in a state where the sheet and the inner sheet are overlapped (see Patent Documents 1 and 2).

  The outer sheet includes an outer sheet main body formed in a substantially rectangular shape having a size capable of wrapping a rice ball, and a cut tape disposed in the central portion of the outer sheet main body so as to extend in the longitudinal direction. . The outer sheet includes a pair of cuts (hereinafter also referred to as cuts) extending in the longitudinal direction at one longitudinal end of the outer sheet main body, and each one end of the pair of cuts is an end of the outer sheet. It is formed in contact with the edge. Thereby, since the area | region between a pair of notch parts is isolate | separated from another area | region, the knob | pick part which can be pinched with a finger etc. between a pair of notch parts is formed. On the other hand, the cut tape is configured such that one end portion is positioned between the pair of cut portions. That is, the one end part of the cut tape is located inside the knob part.

  The inner sheet is formed to have substantially the same shape as the outer sheet. The inner sheet is composed of a pair of sheet pieces separable in the width direction. The pair of sheet pieces are configured such that ends positioned on the center side in the width direction of the inner sheet (hereinafter also referred to as inner end portions) overlap in one direction at positions where the cut sheets of the outer sheet overlap. ing. Then, the inner sheet is divided by separating the pair of sheet pieces in the width direction of the inner sheet.

  When packaging rice balls using such a packaging material, the rice balls are packaged so that the inner sheet is interposed between the rice balls and the laver. Thereby, since a rice ball and a laver do not contact directly, it is suppressed that a laver gets wet with the moisture from a rice ball.

  In addition, when eating a rice ball packaged using such a packaging material, by picking the knob and pulling it along the longitudinal direction of the outer sheet, each other end of the pair of notches is the starting point. The outer sheet is cut along the cut tape. Thereby, the area between the pair of cutting lines extending in the longitudinal direction starting from each other end of the pair of cut portions is separated from the other areas, and the outer sheet is divided in the width direction. And by pulling together with the inner sheet so that the outer sheet divided into two is separated in the width direction, a pair of sheet pieces constituting the inner sheet is separated, the inner sheet is divided, and the seaweed and rice balls It is pulled out from between. Thereby, it becomes possible to eat rice balls in a state where the seaweed and rice balls are integrated.

  However, when packaging rice balls using the packaging material as described above, the moisture of the rice balls passes between the inner ends of the pair of sheet pieces in the region where the inner ends of the pair of sheet pieces overlap. The seaweed enters the space between the outer sheet and the inner sheet (that is, the space in which the seaweed is accommodated), so that the seaweed may become wet.

  Then, this invention makes it a subject to provide the packaging material for cooked rice processed foods which can suppress that the sheet-like food accommodated between the outer sheet | seat and the inner sheet | seat gets wet.

  The packaged food for cooked rice food according to the present invention includes an outer sheet configured to be split in one direction perpendicular to one direction, and an inner sheet configured from a pair of sheet pieces separable in the same direction as the outer sheet. In the packaging material for cooked rice foods formed by sealing the outer sheet and the inner sheet so as to surround the sheet-like food in a state where the outer sheet and the inner sheet are overlapped via the sheet-like food The inner sheet is provided with a polymerization region formed by overlapping the ends of a pair of sheet pieces in a region between both ends in the other direction, and the interval between both ends of the polymerization region in the other direction is: A region on the center side is configured to be wider than a region on both ends of the inner sheet in one direction.

  According to such a configuration, an interval between both ends of the overlapping region in the other direction (hereinafter, also referred to as a polymerization interval) is such that the region on the center side is wider than the region on both ends of the inner sheet in one direction. Therefore, when packaging processed cooked food, the moisture of the cooked cooked food is prevented from entering the space between the inner sheet and the outer sheet (hereinafter also referred to as a sheet-shaped food storage space). be able to.

  Specifically, in the polymerization region, since the ends of the pair of sheet pieces (hereinafter also referred to as inner ends) overlap each other, the cooked rice processed food is packaged using the cooked rice processed food packaging material according to the present invention. When this is done, there is a gap formed between the inner end portions of the space that contacts one surface of the inner sheet (space on the cooked rice side) and the space that contacts the other surface (storage space for the sheet-like food). It is easy to be in a state of communication through the network. In such a state, the moisture of the cooked rice processed food easily enters the accommodation space for the sheet-shaped food through the inner ends. In particular, such intrusion of moisture is likely to occur in a region closer to the center than both ends of the inner sheet in one direction.

  On the other hand, by being configured so that the polymerization interval is wider in the region on the center side than the both ends of the inner sheet in one direction, in the region where the polymerization interval is wide, the cooked rice processing that has entered between the inner end portions A path (hereinafter also referred to as a moisture flow path) until the moisture of the food reaches the accommodation space for the sheet-like food becomes longer. Moreover, in the area | region where a superposition | polymerization space | interval is wide, between inner side edge parts, the space (space on the cooked rice processed food side) which touches one surface of an inner sheet, and the space (housing space for sheet-like food) which touches the other surface It is difficult to form a gap (that is, a moisture flow path) that communicates with each other. For this reason, it can suppress that the moisture of cooked rice processed food penetrate | invades into accommodation space.

  The polymerization region is preferably composed of a first polymerization region extending in one direction and a second polymerization region formed so as to protrude in the other direction from the first polymerization region.

  According to such a configuration, the polymerization region is composed of the first polymerization region extending in one direction and the second polymerization region formed so as to protrude in the other direction from the first polymerization region. In the polymerization region, the polymerization interval is wider than that in the first polymerization region. For this reason, in the 2nd superposition | polymerization area | region, the flow path of the moisture which reaches the accommodation space of a sheet-like food becomes long. Further, in the second polymerization region, a space in contact with one surface of the inner sheet (space on the cooked rice processed food side) and a space in contact with the other surface (storage space for the sheet-like food) are provided between the inner end portions. It is difficult to form a gap (that is, a moisture channel) that allows communication. For this reason, it can suppress that the moisture of cooked rice processed food penetrate | invades into accommodation space. Moreover, the inflow of moisture at a desired position can be effectively suppressed by providing the second polymerization region at a position where it is desired to suppress the inflow of moisture into the accommodation space.

  Each end of the pair of sheet pieces forming the overlapping region has a first end extending in one direction, and at least one end of each end of the pair of sheet pieces forming the overlapping region is It is preferable that a second end portion formed so as to protrude in the other direction from the first end portion is provided.

  According to such a structure, each edge part (each inner edge part) of a pair of sheet piece which forms a superposition | polymerization area | region is equipped with the 1st end part extended in one direction, and a pair of sheet piece which forms a superposition | polymerization area | region At least one of the end portions of each of the first and second end portions includes a second end portion formed so as to protrude in the other direction from the first end portion, thereby overlapping each inner end portion to form a polymerization region. In this case, the first polymerization region is formed by the portion including the first end portion, and the second polymerization region is formed by the portion including the second end portion. For this reason, the inflow of moisture at a desired position can be effectively suppressed by providing the second end portion at a position where it is desired to suppress the inflow of moisture into the accommodation space.

  When packaging the cooked rice processed food, it is preferable to provide the second polymerization region in a region arranged below the cooked rice processed food in the inner sheet.

  According to such a configuration, when the cooked rice processed food is packaged with the packaging material for cooked rice processed food according to the present invention, the cooked rice is disposed in a region (hereinafter also referred to as a lower region) disposed below the cooked rice processed food in the inner sheet. The weight of processed food is added (becomes in close contact). For this reason, when packaging cooked rice food so that at least a part of the polymerization region becomes the lower region, the moisture of the cooked rice food from the portion located below the cooked rice food in the polymerization region accommodates the sheet-like food. It becomes easy to enter the space.

  On the other hand, by providing the second polymerization region in the lower region, the moisture flow path in the lower region becomes longer, and the space in contact with one surface of the inner sheet between the inner end portions in the lower region ( It is difficult to form a gap (that is, a moisture flow path) that allows communication between the cooked rice processed food space and the space in contact with the other surface (sheet food storage space). For this reason, the penetration | invasion of moisture to the accommodation space of the sheet-like foodstuff in a lower area | region can be suppressed effectively.

  As mentioned above, according to this invention, it can suppress that the sheet-like food accommodated between the outer sheet | seat and the inner sheet | seat gets wet.

  Further, the inner sheet 2 includes a superposed region 2c formed by overlapping inner end portions 2a1 and 2b1 of the pair of sheet pieces 2a and 2b in a region between both end portions 21 and 22 in the second direction. The overlapping region 2c is formed so as to extend in the first direction (specifically, in a belt shape) at the central portion of the inner sheet 2 in the second direction. Moreover, the superposition | polymerization area | region 2c is formed over the whole region between the both ends of the inner sheet 2 in a 1st direction. Further, the overlapping region 2c is formed such that the distance between both end portions in the second direction (hereinafter also referred to as a polymerization interval) is wider in the central region than the region on both end sides of the inner sheet 2 in the first direction. The The overlapping region 2c includes a first overlapping region 2c1 formed by overlapping the first end portions 2a3 and 2b3 of the pair of sheet pieces 2a and 2b, and a second end portion of the pair of sheet pieces 2a and 2b. 2a4 and 2b4 are composed of a second polymerization region 2c2 formed by overlapping each other.

  Specifically, the overlapping region 2c includes two first overlapping regions 2c1 (specifically, strip-shaped) extending in the first direction.

That is, the polymerization interval W2 of the second polymerization region 2c2 is configured to be wider than the polymerization interval W1 of the first polymerization region 2c1. Further, the second polymerization region 2c2 is continuously widened as the polymerization interval W2 increases from the both end portions of the second polymerization region 2c2 in the first direction toward the central portion (that is, widest in the central portion in the first direction). Formed).

  As described above, the packaged food for cooked rice food according to the present invention can prevent the sheet-like food contained between the outer sheet and the inner sheet from getting wet.

  That is, the interval between the two end portions of the overlapping region 2c (the overlapping interval) in the second direction is configured so that the region on the center side is wider than the region on both end sides of the inner sheet 2 in the first direction. When the cooked rice processed food A is packaged, the moisture of the cooked rice processed food A can be prevented from entering the space between the inner sheet 2 and the outer sheet 3 (the storage space for the sheet-like food B).

  Specifically, in the superposition | polymerization area | region 2c, since the edge part (inner edge part) 2a1, 2b1 of a pair of sheet piece 2a, 2b has overlapped, the cooked rice processed food A using the packaging material 1 which concerns on this embodiment. When the food is packaged, a space that contacts one surface of the inner sheet 2 (space on the processed rice A side) and a space that contacts the other surface (the storage space for the sheet-like food B) are the inner end portions 2a1 and 2b1. It is easy to be in a state of communication through a gap formed between the two. In such a state, the moisture of the cooked rice processed food A easily enters the accommodation space for the sheet-like food B through the space between the inner ends 2a1 and 2b1. In particular, such intrusion of moisture is likely to occur in a region closer to the center than both ends of the inner sheet 2 in the first direction.

  On the other hand, by being configured so that the polymerization interval is wider in the region on the center side than the both ends of the inner sheet 2 in the first direction, the region between the inner end portions 2a1 and 2b1 is wide in the region where the polymerization interval is wide. A path (hereinafter also referred to as a moisture flow path) until the moisture of the processed rice cooked food A reaches the accommodation space for the sheet-like food B becomes longer. Moreover, in the area | region where a superposition | polymerization space | interval is wide, between inner side edge part 2a1, 2b1, the space (space on the rice processed food A side) which touches one surface of the inner sheet 2, and the space (sheet-like foodstuff) which contact | connect the other surface It is difficult to form a gap (that is, a moisture flow path) that communicates with the B storage space. For this reason, it can suppress that the moisture of cooked rice processed food A penetrate | invades into accommodation space.

  In addition, since the polymerization region 2c includes a first polymerization region 2c1 extending in the first direction and a second polymerization region 2c2 formed so as to protrude from the first polymerization region 2c1 in the second direction, In the double polymerization region 2c2, the polymerization interval is wider than that in the first polymerization region 2c1. For this reason, in the 2nd superposition | polymerization area | region 2c2, the flow path of the moisture which reaches the storage space of the sheet-like food B becomes long. Moreover, in 2nd superposition | polymerization area | region 2c2, between inner side edge part 2a1, 2b1, the space (space on the rice processed food A side) which touches one surface of the inner sheet 2, and the space (sheet-like foodstuff) which contact | connects the other surface It is difficult to form a gap (that is, a moisture flow path) that communicates with the B storage space. For this reason, it can suppress that the moisture of cooked rice processed food A penetrate | invades into accommodation space. Further, by providing the second polymerization region 2c2 at a position where it is desired to suppress the inflow of moisture into the accommodation space, the inflow of moisture at a desired position can be effectively suppressed.

  Moreover, each edge part (each inner edge part) 2a1, 2b1 of a pair of sheet piece 2a, 2b which forms the superposition | polymerization area | region 2c is provided with 1st end part 2a3, 2b3 extended in a 1st direction, and superposition | polymerization area | region 2c is provided. At least one inner end 2a1 (or the other inner end 2b1) of each end (each inner end) 2a1, 2b1 of the pair of sheet pieces 2a, 2b to be formed is the first end 2a3 (or The second end 2a4 (or the second end 2b4) is formed so as to protrude in the second direction from the first end 2b3), so that the inner ends 2a1 and 2b1 are overlapped with each other. When the polymerization region 2c is formed, the first polymerization region 2c1 is formed by the portion including the first end portions 2a3 and 2b3, and the second polymerization is performed by the portion including the second end portion 2a4 (or the second end portion 2b4). Region 2c2 is formed. For this reason, by providing the second end 2a4 (or the second end 2b4) at a position where it is desired to suppress the inflow of moisture into the accommodation space, the inflow of moisture at a desired position can be effectively suppressed. .

  Moreover, when the cooked rice processed food A is packaged with the packaging material 1 according to the present invention, the weight of the cooked rice processed food A in a region (hereinafter also referred to as a lower region) disposed below the cooked rice processed food A in the inner sheet 2. Will be added (becomes in close contact). For this reason, when packaging the cooked rice processed food A so that at least a part of the polymerization region 2c becomes the lower region, the moisture of the cooked rice processed food A from the portion located below the cooked rice processed food A in the polymerization region 2c. It becomes easy to enter the accommodation space for the sheet-like food B.

  On the other hand, by providing the second polymerization region 2c2 in the lower region, the moisture flow path in the lower region becomes longer, and between the inner ends 2a1, 2b1 in the lower region, one of the inner sheets 2 It is difficult to form a gap (that is, a moisture flow path) that communicates the space in contact with the surface (space on the cooked rice A) and the space in contact with the other surface (the storage space for the sheet-like food B). For this reason, the penetration | invasion of the moisture to the accommodation space of the sheet-like food B in a lower area | region can be suppressed effectively.

  Moreover, in the 2nd superposition | polymerization area | region 2c2, since the weight of the cooked rice processed food A is added and a superposition | polymerization space | interval becomes wide, when it applies force in the direction isolate | separated with respect to a pair of sheet piece 2a, 2b, it arises in the superposition | polymerization area | region 2c. The resistance (the resistance generated between the inner end portions 2a1 and 2b1) is larger in the second polymerization region 2c2 than in the first polymerization region 2c1. Thereby, separation | separation of a pair of sheet piece 2a, 2b is performed smoothly more than needed, and it can prevent that the cooked rice processed food A falls out from the packaging material 1.
