Description

  The present invention is configured so that, for example, a sheet-like food such as sheet-like seaweed and a cooked rice food such as a triangular rice ball can be packaged in a separated state, while being eaten, they are packaged in a separated state. It is related with the packaging material for cooked rice processed food comprised so that it can eat in the state which opened both and united.

  Rice balls with seaweed sold at convenience stores and the like are packaged with a packaged rice cooked food (hereinafter also referred to as “packaging material”) containing seaweed between an outer sheet and an inner sheet. In this way, since the seaweed is stored between the outer sheet and the inner sheet, the rice ball and the seaweed are not in direct contact with each other, so it is possible to prevent the seaweed from getting wet. Yes.

  The outer sheet is formed in, for example, a substantially rectangular shape that can wrap a rice ball. In addition, the outer sheet has a cut tape attached to the inner (inner sheet side) surface on a center line that connects the center portions of both ends in the length direction. For this reason, by pulling the cut tape, the outer sheet is cut along the cut tape and divided in the width direction.

  The inner sheet is composed of two sheet bodies. When the two sheets are superposed on each other, the inner end of one sheet and the inner end of the other sheet are vertically moved on the center line of the outer sheet. It is configured to overlap. Thereby, it is comprised so that it can divide | segment easily in the width direction (same direction as an outer sheet | seat) of an inner sheet | seat.

  When eating a rice ball packaged using the packaging material having such a configuration, the outer sheet is cut and divided by picking and pulling the end of the cut tape. And the inner sheet is also divided | segmented by pulling the outer sheet | seat divided | segmented into two with the inner sheet | seat in the direction which separates. Thereby, an inner sheet | seat is pulled out from between nori and a rice ball, a nori and a rice ball become united, and it becomes possible to eat a rice ball (refer patent documents 1 and 2).

  In the packaging material as described above, the outer sheet is cut along the cut tape. Specifically, when a strip-shaped cut tape is disposed along the cutting direction of the outer sheet, the outer sheet is cut along a pair of outer edges extending in the longitudinal direction. For this reason, when forming the area where the outer sheet is to be cut partially wide, use a cut tape whose outer edge is partially enlarged, or cut the tape along the shape of the area where the outer sheet is cut. It is necessary to arrange the sheet or to attach another sheet having a width wider than the width of the cut tape to the cut tape.

  However, when the shape of the area where the outer sheet is cut differs from product to product, a cut tape corresponding to each product is produced, or a cut tape is arranged along the shape of the area where the outer sheet is cut for each product. This requires labor and cost. Moreover, when attaching another sheet wider than the width of the cut tape to the cut tape, as described above, it takes time and cost, and the thickness of the area where the other sheet is attached to the outer sheet is larger than that of the other area. Also thicken. For this reason, when a long outer sheet is wound into a roll shape, meandering may occur, or the wound state may collapse.

  Then, this invention provides the packaging material for cooked rice processed foods which can prevent the thickness of an outer sheet from increasing partially, and can easily expand the area | region where an outer sheet | seat is cut | disconnected. Is an issue.

  The packaged food for cooked rice food according to the present invention is formed so as to be divided in the width direction by being cut along a pair of virtual lines extending in the longitudinal direction, and to be divided in the same direction as the outer sheet. A packaged food for cooked rice products, wherein the outer sheet and the inner sheet are sealed 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 outer sheet includes a cut portion formed by cutting in a line shape so that a region inside the outer peripheral portion intersects with one imaginary line, and the outer sheet includes the cut portion and one imaginary line. The region on the one end side in the longitudinal direction from the crossing position is configured to be cut on one imaginary line, and the end of the cut portion located outside the pair of imaginary lines has one imaginary line and the cut portion Formed on the other end in the longitudinal direction of the outer sheet, And wherein the Rukoto.

  According to such a configuration, the outer sheet is cut in the longitudinal direction on one imaginary line in the region on the one end side in the longitudinal direction from the intersection position of the cut portion and one imaginary line in the outer sheet, and the other The outer sheet is cut in the longitudinal direction along the imaginary line. Thereby, the area | region (henceforth 1st isolation | separation part) between the part cut | disconnected on one virtual line and the part cut | disconnected along the other virtual line is isolate | separated from another area | region.

  At this time, a portion cut on one imaginary line in the outer sheet and a portion cut by the cut portion are connected. In addition, by pulling the first separation portion to the other end side of the outer sheet, the outer sheet extends in the longitudinal direction along a region corresponding to the cut portion in the other imaginary line (hereinafter also referred to as a cut portion corresponding portion). Disconnected. Thereby, the area | region (henceforth a 2nd separation part) between the part cut | disconnected along the notch part corresponding | compatible part of the other virtual line, and a notch part, and the 1st separation part are united and others. Separated from the area.

  And the first separation part and the second separation part are integrated and further pulled to the other end side in the longitudinal direction of the outer sheet, so that the end part of the cut part located outside the pair of imaginary lines (hereinafter, The region on the other end side in the longitudinal direction in the outer sheet (hereinafter also referred to as the other end region in the longitudinal direction) than the outer end portion) is based on the outer end portion of the cut portion (that is, a pair of outer sheet portions). In the longitudinal direction (at the area outside the imaginary line), such area is cut along the other imaginary line.

  Thereby, in the other end side region in the longitudinal direction of the outer sheet, the region between the portion cut from the outer end of the cut portion as a base point and the portion cut along the other imaginary line (hereinafter referred to as the first) Are also separated from other regions integrally with the first separation part and the second separation part.

  Such a third separation portion is formed wider in the width direction of the outer sheet than the first separation portion because the outer end portion of the cut portion is located outside the pair of virtual lines. Thereby, the exposed area of a sheet-like foodstuff becomes larger in the 3rd separation part in an outer sheet than the 1st separation part in an outer sheet. That is, the area | region where an outer sheet | seat is cut | disconnected can be expanded easily, without using the other sheet | seat body which increases the thickness of an outer sheet | seat partially like the past.

  The same applies to the following, but “intersection” means that the end opposite to the end of the notch located outside the virtual line (outside the pair of virtual lines) penetrates the virtual line. It is a concept that includes both a form located inside the imaginary line (inside a pair of imaginary lines) and a form in which the opposite end stops or touches the imaginary line without penetrating the imaginary line.

  The outer sheet further includes a cut portion formed by being cut in a linear shape so that a region inside the outer peripheral portion intersects with the other virtual line, and the outer sheet and the other virtual line The region on the one end side in the longitudinal direction from the crossing position is configured to be cut on the other virtual line, and the end of the cut portion located outside the pair of virtual lines has the other virtual line and the cut portion It is preferable to be formed on the other end side in the longitudinal direction of the outer sheet rather than the crossing position.

  According to such a configuration, the outer sheet includes a pair of cut portions, and is configured such that one cut portion intersects with one virtual line and the other cut portion intersects with the other virtual line. The And in the area | region of the one end side of a longitudinal direction rather than the crossing position of a pair of notch part and a pair of virtual line in an outer sheet | seat, an outer sheet | seat is cut | disconnected in a longitudinal direction on a pair of virtual line. Thereby, the area | region (henceforth 1st isolation | separation part) between a pair of virtual lines is isolate | separated from another area | region. At this time, a portion cut by the pair of imaginary lines in the outer sheet and a portion cut by the pair of cut portions are continuous. Thereby, the area | region (henceforth a 2nd separation part) between a pair of notch parts, and a 1st separation part are united, and it isolate | separates from another area | region.

  And each end part of a pair of notch part located in the outer side of a pair of imaginary lines because the 1st separation part and the 2nd separation part are united, and are further pulled to the other end side of the longitudinal direction of an outer sheet A region on the other end side in the longitudinal direction in the outer sheet (hereinafter also referred to as the other end side region in the longitudinal direction) than the outer end portion (hereinafter also referred to as the outer end portion) is based on each outer end portion of the pair of cut portions (ie, , In the longitudinal direction (in the region outside the pair of imaginary lines in the outer sheet). Thereby, in the other end side region in the longitudinal direction of the outer sheet, the region between the portions cut from the respective outer end portions of the pair of cut portions (hereinafter also referred to as a third separation portion) is first separated. It is separated from other regions as a unit with the second part and the second separation part.

  Such a third separation portion is formed wider in the width direction of the outer sheet than the first separation portion because the outer end portions of the pair of cut portions are located outside the pair of imaginary lines. . Thereby, the exposed area of a sheet-like foodstuff becomes larger in the 3rd separation part in an outer sheet than the 1st separation part in an outer sheet. That is, the area | region where an outer sheet | seat is cut | disconnected can be expanded easily, without using the other sheet | seat body which increases the thickness of an outer sheet | seat partially like the past.

  It is preferable that the pair of cut portions are formed at spaced positions, and a space is formed between the end portions located inside the pair of virtual lines.

  According to such a structure, a pair of notch part does not cross | intersect because a pair of notch part is formed in the space | interval position. And the space | interval between the edge parts (henceforth an inner edge part) of the notch part located inside a pair of virtual lines forms the area | region between the inner edge parts of a pair of notch part Are continuous along the longitudinal direction of the outer sheet between the pair of virtual lines. For this reason, the first separation portion can be pulled along the longitudinal direction of the outer sheet, and the outer sheet can be easily cut.

  The incision portion includes a first incision portion that intersects the longitudinal direction of the outer sheet, and a pair of incision portions that are connected to both end portions of the first incision portion and are formed along the longitudinal direction of the outer sheet. It is preferably composed of two parts.

  According to such a configuration, when a tension is applied along the longitudinal direction with respect to the outer sheet, the outer sheet is prevented from being unintentionally broken with both ends of the cut portion serving as a base point. be able to. Specifically, when the cut portion is formed only by the first cut portion, when a tension is applied along the longitudinal direction with respect to the outer sheet, a force that tears the outer sheet in the width direction is cut. Since the outer sheet is added to the outer sheet with the end of the portion as a base point, the outer sheet is easily broken.

  On the other hand, the second cut portion is formed at both ends of the first cut portion, and the cut portion is configured so that tension is applied along the longitudinal direction with respect to the outer sheet. A force that breaks the outer sheet in the width direction is not applied to both ends of the cut portion. For this reason, it can prevent that an outer sheet | seat will fracture | rupture unintentionally in the width direction.

  The outer sheet includes a strip-shaped cut tape extending along a pair of imaginary lines, and the cut tape is preferably arranged so as to intersect with the cut portion inside the pair of imaginary lines.

  According to such a configuration, since the outer sheet includes the cut tape, the outer sheet is cut along the cut tape, so that it is easy to cut the outer sheet along the imaginary line. Moreover, when an outer sheet | seat is cut | disconnected along a cut tape on a virtual line because a cut tape cross | intersects a cut part, a cutting direction can be reliably guide | induced to a cut part. For this reason, it is possible to reliably enlarge the cutting area of the outer sheet with the outer end portion of the cut portion as a base point.

  As described above, according to the present invention, it is possible to prevent the thickness of the outer sheet from partially increasing, and it is possible to easily enlarge the area where the outer sheet is cut.

And the area | regions 2S and 3S surrounding the sheet-like food B are sealed in the state in which the inner sheet 2 and the outer sheet 3 were overlapped via the sheet-like food B such as seaweed wrapped around the cooked rice processed food A. Is.

  The cooked rice processed food A includes various rice balls held in a triangular shape or barrel shape, as well as rice cakes. Further, the sheet-like food B includes tatami rice cake in addition to sheet-like seaweed. In principle, the longitudinal direction and the width direction are determined based on the inner sheet 2, the outer sheet 3, and the sheet-like food B. However, if it is considered confusing, the packaging material 1 (or the inner sheet 2, The longitudinal direction of the outer sheet 3 and the sheet-like food B) may be expressed as the vertical direction and the width direction as the horizontal direction.

  The inner sheet 2 is formed so that one direction is a longitudinal direction (in the present embodiment, in a rectangular shape). Further, the inner sheet 2 is configured so as to be divided in the width direction orthogonal to one direction. Specifically, the inner sheet 2 includes a pair of inner sheet pieces 2a and 2b. The pair of inner sheet pieces 2a and 2b is arranged at the substantially central portion of the inner sheet 2 so as to overlap along the longitudinal direction of the inner sheet 2 (that is, the overlapping region of the pair of inner sheet pieces 2a and 2b is the inner portion). Formed along the longitudinal direction of the sheet 2). Thereby, the inner sheet 2 is configured to be divided in the width direction.

  The outer sheet 3 is formed so that one direction is a longitudinal direction (in the present embodiment, in a rectangular shape). And the outer sheet | seat 3 is piled up on the inner sheet | seat 2 in the state which made the inner sheet 2 and longitudinal directions parallel. Further, the outer sheet 3 is configured to be divisible in the width direction orthogonal to one direction. Specifically, the outer sheet 3 is configured to be divided in the width direction by being cut in the longitudinal direction. That is, the outer sheet 3 is configured to be divided in the same direction as the inner sheet 2.

  The outer sheet 3 will be described in more detail. As shown in FIG. 2, the outer sheet 3 is formed so that one direction is long (in the present embodiment, in a rectangular shape) (specifically, the inner sheet 3 A pair of cut tapes 3b that include an outer sheet main body 3a (formed in a sheet shape that is substantially the same shape as the sheet 2) and that define the direction and width in which the outer sheet 3 (specifically, the outer sheet main body 3a) is divided. , 3c, and thickness adjusting tapes 3d, 3e having substantially the same thickness as the pair of cut tapes 3b, 3c. A pair of cut tapes 3b, 3c and thickness adjusting tapes 3d, 3e are disposed on one surface of the outer sheet body 3a (one surface side of the outer sheet 3), and the other surface of the outer sheet body 3a. On the other surface side of the outer sheet 3, a seal member S is attached so as to cover a pair of cut portions C1 and C2 described later.

  The outer sheet 3 (specifically, the outer sheet main body 3a) is configured to be cut along a pair of virtual lines L1 and L2 extending in the longitudinal direction. The pair of imaginary lines L1 and L2 extends along the longitudinal direction at a substantially central portion in the width direction of the outer sheet 3 (specifically, the outer sheet main body 3a). Further, a predetermined interval is formed between the pair of virtual lines L1 and L2.

  Further, the outer sheet 3 (specifically, the outer sheet main body 3a) has a pair of cut portions formed by cutting a region inside the outer peripheral portion into a linear shape (in the present embodiment, a straight shape). C1 and C2 are provided. The pair of cut portions C1 and C2 is a region on one end side in the longitudinal direction with respect to the central portion in the longitudinal direction of the outer sheet 3 (specifically, the outer sheet main body 3a) (more specifically, the outer portion in the region). It is formed on the center side of the sheet body 3a.

  Further, the pair of cut portions C1 and C2 are formed with an interval in the width direction of the outer sheet 3 (specifically, the outer sheet main body 3a). And a pair of notch part C1, C2 is the space | interval (end of outer sheet main body 3a) between each edge part C1a and C2a located in the one end side of the longitudinal direction of outer sheet 3 (specifically outer sheet main body 3a). The distance along the width direction) is the distance between the end portions C1b and C2b located on the other end side in the longitudinal direction of the outer sheet 3 (specifically, the outer sheet body 3a) (in the width direction of the outer sheet body 3a). It is formed so as to be narrower than (interval along). That is, the pair of cut portions C1 and C2 are formed in a square shape. Below, each edge part (each edge part by the side of a narrow space | interval) of a pair of notch parts C1 and C2 located in the longitudinal direction one end side of the outer sheet | seat 3 (specifically outer sheet | seat main body 3a) is made into inner side. Also referred to as ends C1a and C2a. Further, the ends (the ends on the wide side) of the pair of cut portions C1 and C2 located on the other end side in the longitudinal direction of the outer sheet 3 (specifically, the outer sheet main body 3a) are outside. Also referred to as ends C1b and C2b.

  Further, the pair of cut portions C1 and C2 are formed so as to intersect with the pair of virtual lines L1 and L2. Specifically, one cut portion C1 is formed so as to intersect with one virtual line L1, and the other cut portion C2 is formed so as to intersect with the other virtual line L2. And the area | region of the one end side of the longitudinal direction of the outer sheet | seat 3 can be cut | disconnected on a pair of virtual line L1, L2 rather than crossing position C1c, C2c of a pair of virtual line L1, L2 and a pair of notch part C1, C2 Configured. The pair of notches C1 and C2 has inner end portions C1a and C2a positioned inside the pair of virtual lines L1 and L2, and outer end portions C1b and C2b outside the pair of virtual lines L1 and L2. It is formed so that it may be located in.

  In addition, the pair of cut portions C1 and C2 are arranged such that the outer end portions C1b and C2b are located on the outer sheet 3 (specifically, the outer sheet main body 3a) with respect to the intersection positions C1c and C2c with the pair of virtual lines L1 and L2. ) To be located on the other end side in the longitudinal direction. Further, the outer end portions C1b and C2b are formed so that the interval between the pair of virtual lines L1 and L2 (the interval along the width direction of the outer sheet main body 3a) is wider than the inner end portions C1a and C2a. The In other words, the outer end portions C1b and C2b are spaced apart from the pair of virtual lines L1 and L2 in the width direction of the outer sheet 3 (specifically, the outer sheet main body 3a) than the inner end portions C1a and C2a. Formed.

  In addition, the outer sheet 3 (specifically, the outer sheet main body 3a) is a pick for opening that functions as a knob when the cooked rice A is packaged using the packaging material 1 (when the package is formed). Part 3f is formed. The opening knob 3f is formed by cutting a part of the outer sheet main body 3a (specifically, one end in the longitudinal direction) with an interval in the width direction of the outer sheet main body 3a. In the present embodiment, a knob portion 3f is formed between a pair of opening cuts C3 and C4 formed by cutting one end portion of the outer sheet body 3a in the longitudinal direction on the pair of virtual lines L1 and L2. The

  As shown in FIG. 3, the pair of cut tapes 3 b and 3 c are disposed over substantially the entire region between both ends in the longitudinal direction of the outer sheet 3 (specifically, the outer sheet main body 3 a). Further, the pair of cut tapes 3b and 3c are arranged with a gap in the width direction of the outer sheet 3 (specifically, the outer sheet main body 3a). Further, the pair of cut tapes 3b and 3c are disposed inside the pair of virtual lines L1 and L2. And a pair of cut tapes 3b and 3c are arrange | positioned so that a pair of cut part C1, C2 may be crossed. Specifically, it is arranged such that one cut tape 3b intersects one cut portion C1 and the other cut tape 3c intersects the other cut portion C2. That is, the pair of cut tapes 3b and 3c are arranged along the longitudinal direction of the outer sheet 3 without being cut at the intersection positions with the pair of cut portions C1 and C2. The inner end portions C1a and C2a of the pair of cut portions C1 and C2 are positioned inside the pair of cut tapes 3b and 3c, and the pair of cut tapes 3b and 3c are disposed outside the pair of cut tapes 3b and 3c. The outer end portions C1b and C2b of the insertion portions C1 and C2 are located.

  The pair of thickness adjusting tapes 3d and 3e are arranged along the longitudinal direction of the outer sheet 3 (specifically, the outer sheet main body 3a). Further, the pair of thickness adjusting tapes 3d, 3e are arranged outside the pair of cut tapes 3b, 3c (specifically, near the both end portions in the width direction of the outer sheet main body 3a). Further, the pair of thickness adjusting tapes 3d and 3e are arranged along the pair of cut tapes 3b and 3c. As a result, the outer sheet 3 has a central portion in the width direction (region where the pair of cut tapes 3b and 3c is disposed) and both end portions in the width direction (region where the pair of thickness adjusting tapes 3d and 3e are disposed). And the thickness are substantially the same. For this reason, when the outer sheet 3 is formed in a long shape in the longitudinal direction and wound in a roll shape along the longitudinal direction, winding meandering or collapse caused by a difference in thickness in the width direction is prevented, and winding is performed. Defects can be prevented.

  As shown in FIG. 4, the seal member S is configured to be cut together with the outer sheet 3 when attached to the outer sheet 3 (specifically, the outer sheet main body 3 a). Specifically, the seal member S includes a pair of cutting auxiliary lines S1 and S2 configured by perforations, half cuts, and the like. The pair of auxiliary cutting lines S1 and S2 includes the first auxiliary lines S1a and S2a that overlap with the pair of virtual lines L1 and L2 and the pair of cut portions C1 when the seal member S is attached to the outer sheet 3. , C2 and the second auxiliary lines S1b, S2b and the outer end portions C1b, C2b of the pair of cut portions C1, C2 along the longitudinal direction of the outer sheet 3 (that is, the pair of virtual lines L1, L2). The third auxiliary lines S1c and S2c are formed.

  The outer sheet 3 having the above configuration has a pair of imaginary lines in a region on one end side in the longitudinal direction from the intersection positions C1c and C2c between the pair of cut portions C1 and C2 and the pair of imaginary lines L1 and L2. The outer sheet 3 is cut in the longitudinal direction on L1 and L2. Specifically, the outer sheet 3 is picked up on the pair of imaginary lines L1 and L2 by picking the knob 3f and pulling it to the other end side in the longitudinal direction of the outer sheet 3 on the pair of opening cuts C3 and C4. Is cut in the longitudinal direction. Thereby, the area | region (henceforth 1st isolation | separation part R1) between a pair of virtual lines L1, L2 is isolate | separated from another area | region.

  Under the present circumstances, a space | interval is formed between inner side edge part C1a, C2a because a pair of notch part C1, C2 is formed in the position which left | separated. Thereby, the area | region between inner side edge part C1a, C2a is continued along the longitudinal direction of the outer sheet | seat 3 between a pair of virtual lines L1, L2. For this reason, the first separation portion R1 can be pulled along the longitudinal direction together with the pair of cut tapes 3b and 3c, and the outer sheet 3 can be easily cut.

  When the pair of cut tapes 3b and 3c intersect the pair of cut portions C1 and C2, the outer sheet is cut along the pair of cut tapes 3b and 3c on the pair of virtual lines L1 and L2. The cutting direction can be reliably guided to the pair of cut portions C1 and C2.

  Thereby, the part cut | disconnected by a pair of virtual line L1, L2 in the outer sheet | seat 3 and the part cut | disconnected by a pair of cut part C1, C2 continue, and the area | region (henceforth, hereinafter) between a pair of cut part The second separation portion R2) and the first separation portion R1 are integrally separated from other regions.

  And the 1st separation part R1 and the 2nd separation part R2 are united, and are further pulled to the other end side of the longitudinal direction of outer sheet 3, each outside end part C1b of a pair of cut parts C1 and C2, A region on the other end side in the longitudinal direction in the outer sheet with respect to C2b (hereinafter also referred to as a region on the other end in the longitudinal direction) is based on the outer end portions C1b and C2b (that is, outside the pair of virtual lines in the outer sheet). In the longitudinal direction). Thereby, in the other end side region in the longitudinal direction of the outer sheet 3, a region (hereinafter referred to as a third separating portion) between portions cut from the outer end portions C1b and C2b of the pair of cut portions C1 and C2 as base points. R3) is integrated with the first separation portion R1 and the second separation portion R2 and separated from other regions.

  The third separation portion R3 is configured such that the outer end portions C1b and C2b of the pair of cut portions C1 and C2 are positioned outside the pair of virtual lines L1 and L2, and thus the outer sheet 3 is more than the first separation portion R1. It is formed wide in the width direction. Thereby, the area | region where the outer sheet | seat 3 is cut | disconnected can be expanded easily, without using the other sheet | seat body which increases the thickness of an outer sheet | seat partially like the past.

  When the outer sheet 3 is cut as described above, the sealing member S is also cut in a shape corresponding to the outer sheet 3. Specifically, a region between the first auxiliary lines S1a and S2a is cut corresponding to the first separation portion R1 and separated from other regions. Further, the region between the second auxiliary lines S1b and S2b is cut corresponding to the second separation portion R2 and separated from other regions. The region between the third auxiliary lines S1c and S2c is cut corresponding to the third separation portion R3 and separated from the other regions.

  As described above, according to the packaged food for cooked rice food according to the present invention, the thickness of the outer sheet can be prevented from partially increasing, and the region where the outer sheet is cut can be easily expanded. be able to.

  The packaged food for cooked rice food according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention. Further, the configurations and methods of the plurality of embodiments described above may be arbitrarily adopted and combined (even if the configurations and methods according to one embodiment are applied to the configurations and methods according to other embodiments). Of course, it is of course possible to arbitrarily select configurations, methods, and the like according to various modifications described below and employ them in the configurations, methods, and the like according to the above-described embodiments.

  For example, in the said embodiment, although the outer sheet | seat 3 is equipped with a pair of notch part C1, C2, it is not limited to this, As shown to Fig.5 (a), one notch part C1 May be provided. According to such a configuration, in the region on the one end side in the longitudinal direction from the intersection position C1c between the cut portion C1 and the one virtual line L1 in the outer sheet 3, the outer sheet 3 is longitudinal in the longitudinal direction on the one virtual line L1. And the outer sheet is cut in the longitudinal direction along the other virtual line L2. Thereby, the area | region (namely, 1st isolation | separation part R1) between the part cut | disconnected along one virtual line L1 and the part cut | disconnected along the other virtual line L2 is isolate | separated from another area | region. At this time, a portion cut on one imaginary line L1 in the outer sheet 3 and a portion cut by the cut portion C1 are connected.

  Further, by pulling the first separation portion R1 toward the other end side of the outer sheet 3, the first separation portion R1 is removed along a region corresponding to the cut portion C1 in the other virtual line L2 (hereinafter also referred to as a cut portion corresponding portion). The sheet 3 is cut in the longitudinal direction. Thereby, the area | region (henceforth 2nd separation part R4) between the part cut | disconnected along the notch part corresponding | compatible part of the other virtual line L2, and a notch part, and 1st separation part R1 are united. Separated from other areas.

  And the 1st separation part R1 and the 2nd separation part R4 are united and are pulled further to the other end side of the longitudinal direction of outer sheet 3, and it is an outer sheet rather than the outside edge part C1b of one notch part C1. 3 is a region on the other end side in the longitudinal direction (hereinafter also referred to as a region on the other end side in the longitudinal direction) based on the outer end C1b (that is, a region outside the pair of virtual lines L1 and L2 in the outer sheet 3). And) in the longitudinal direction and such a region is cut along the other virtual line L2. Thereby, in the longitudinal direction other end side area | region of the outer sheet | seat 3, the area | region between the part cut | disconnected from the outer side edge part C1b of the notch part C1, and the part cut | disconnected along the other virtual line L2 (Hereinafter also referred to as a third separation portion R5) is separated from other regions integrally with the first separation portion R1 and the second separation portion R2.

  The third separation portion R5 is formed wider in the width direction of the outer sheet 3 than the first separation portion R1 because the outer end C1b of the cut portion C1 is located outside the pair of virtual lines L1 and L2. Will be. Thereby, the exposed area of the sheet-like food B becomes larger in the third separation portion R5 in the outer sheet 3 than in the first separation portion R1 in the outer sheet 3. That is, the area | region where the outer sheet | seat 3 is cut | disconnected can be expanded easily, without using the other sheet | seat body which increases the thickness of an outer sheet | seat partially like the past.

  Moreover, in the said embodiment, although the outer sheet | seat 3 is equipped with a pair of cut tapes 3b and 3c, it is not limited to this, As shown in FIG.5 (b), a pair of cut part C1, You may comprise so that the one cut tape 3g may be provided so that both of C2 may be crossed (specifically so that each inner side edge part C1a and C2a may be covered).

  Moreover, in the said embodiment, although a pair of cut part C1, C2 is formed in the width direction of the outer sheet | seat 3 at intervals, it is not limited to this, As shown to Fig.6 (a) In addition, they may be formed at intervals in the longitudinal direction.

  Moreover, in the said embodiment, although a pair of cut part C1, C2 is formed in linear form, as shown in FIG.6 (b), it is not limited to this, The longitudinal direction of the outer sheet | seat 3 (Specifically, the first cut portions C5d and C6d intersecting the pair of virtual lines L1 and L2) and the longitudinal direction of the outer sheet 3 connected to both ends of the first cut portions C5d and C6d ( Specifically, the cut portions C5 and C6 may be configured by a pair of cut second portions C5e and C6e formed along a pair of virtual lines L1 and L2).

  According to such a configuration, when tension is applied to the outer sheet 3 along the longitudinal direction, the outer sheet 3 is prevented from being easily broken by using both end portions of the cut portions C5 and C6 as the base points. can do. Specifically, when the cut portion is formed only by the first cut portions C5d and C6d, when tension is applied along the longitudinal direction with respect to the outer sheet 3, the outer sheet 3 is torn in the width direction. Since a strong force is applied to the outer sheet 3 starting from the end of the cut portion, the outer sheet 3 is easily broken.

  On the other hand, the cut second portions C5e, C6e are connected to both ends of the cut first portions C5d, C6d to form the cut portions C5, C6. Even when a tension is applied along, the force that breaks the outer sheet 3 in the width direction is not applied to both end portions of the cut portions C5 and C6. For this reason, it is possible to prevent the outer sheet 3 from being unintentionally broken in the width direction.

  Moreover, as shown in FIG.6 (c), you may comprise a pair of cut part C7, C8 by several cut part piece C7a, C8a. A plurality of incision pieces C7a, C8a are arranged at intervals in the longitudinal direction of the outer sheet 3, and each of the incision piece pieces C7a, C8a is in the width direction as it goes to the other end side in the longitudinal direction of the outer sheet 3. Are formed at different positions, and the end portion located on the other end side in the longitudinal direction of the outer sheet 3 in one cut piece C7a, C8a is the width direction of the other cut piece C7a, C8a and the outer sheet 3 You may form so that it may overlap.

  Moreover, in the said embodiment, although a pair of cut part C1, C2 is formed in linear form, it is not limited to this, For example, you may form in circular arc shape, or a dogleg shape. It may be formed in a shape.
