Description

  The present invention relates to a packaged food for cooked rice food for packaging cooked rice processed food.

  Conventionally, various food packaging materials for processing cooked rice products that have been processed into chunks of cooked rice have been provided, but in recent years, processed rice food products and sheet food products such as laver and thin-cooked eggs In addition, the processed rice food and the sheet-like food can be integrated and eaten together at the time of opening.

  Such a packaged food for cooked rice food is composed of an outer film that can be divided in the width direction and an outer film that is overlapped with the outer film via a sheet-like food, and can be separated in the same direction as the dividing direction of the outer film. And a film.

  The outer film generally has a linear or strip-shaped cutting auxiliary means (for example, a cut tape) for cutting (dividing) the outer film at the center in the width direction over the entire length in the length direction perpendicular to the width direction. And a gripping portion including the cutting assisting means is formed at least at one end portion in the length direction. The gripping portion is formed by making a cut at one end of the outer film. That is, the outer film has a pair of cuts so as to interpose one end of the cutting assisting means, and a gripping part is formed between the cuts.

  As a result, the outer film is in a state where the end of the cutting assisting means is also held together when the holding part is picked, and the outer film is cut in the length direction by the cutting auxiliary means by pulling the holding part. It can be divided into two in the direction. On the other hand, the inner film is composed of two films arranged in parallel in the width direction of the outer film, and the two films can be separated in the same direction as the outer film.

  The outer film and the inner film are sealed so as to form a linear or belt-like seal line surrounding the sheet-like food interposed between the outer film and the inner film. The packaging material for cooked rice processed food of the above configuration is the length of the outer film in order to avoid that the seal lines on both ends in the length direction intersect the cutting assisting means and the gripping part is sealed by the inner film. A seal line on one end side in the direction is formed so as to be divided into a gripping portion side and a region where sheet-like food is interposed.

  The packaging material for cooked rice processed food of the above configuration heats the ends facing each other by folding in half the length direction with the cooked rice food disposed on the inner film (two films arranged in parallel). By sealing, the cooked rice processed food and the sheet-like food can be packaged in a state separated by an inner film.

The packaged food for cooked rice processed food is separated (separated) from the outer film and the inner film (two films) divided into two parts by cutting the outer film in the length direction and pulling in the width direction. The inner film (two films) is pulled out between the sheet-like food and the cooked rice processed food. Thereby, it will be in the state which can eat a sheet-like food and cooked-rice processed food integrally in connection with opening (for example, refer patent document 1).
JP 2005-095111 A

  However, the packaged food for cooked rice food having the above-described configuration is configured to cut the outer film with a single cutting assisting means having a linear shape or a strip shape. A part will be in the state facing the sheet-like food. For this reason, most of the sheet-like food is sandwiched between the outer film and the inner film, and the sheet-like food may be torn when the divided outer film is pulled in the width direction.

  Also, since the rigidity of the seal line is increased at the site where the outer film and the inner film are sealed (bonded), the seal line intersects with the cutting assisting means when the outer film is cut by pulling the gripping portion. However, there was a case where the outer film could not be smoothly opened because the cutting of the outer film was hindered.

  Then, this invention makes it a subject to provide the packaging material for cooked rice processed foods which can be opened smoothly without tearing a sheet-like foodstuff at the time of opening in view of such a situation.

  The packaged food for cooked rice food according to the present invention is provided with linear or belt-shaped cutting assisting means over the entire length in the length direction orthogonal to the width direction so that the packaging material can be divided in the width direction. An outer film in which a gripping portion including the cutting assisting means is formed at least at one end in the vertical direction is superimposed on the outer film via a sheet-like food, and can be separated in the same direction as the outer film dividing direction. The inner film is sealed so that the outer film and the inner film form a linear or belt-like seal line surrounding the sheet-like food, and the seal lines on both ends in the length direction intersect the cutting assisting means. In the packaging material for cooked rice processed food, wherein the seal line on one end side in the length direction separates the gripping portion side from the region where the sheet-like food is interposed, the outer film is the cutting aid Means is wide Two strips are provided at intervals in the direction, and the gripping portion is formed so as to straddle the two cutting assisting means, and at least one of the outer film and the inner film includes seal lines on both end sides in the length direction. It is characterized in that an easy peel property is imparted to a region between at least two strips of cutting assisting means. Here, “easy peelability” refers to the property that the sealed outer film and the inner film can be easily peeled off. For example, a resin having high peelability (for example, the outer film and the inner film are bonded by heat welding). In the case of sealing, easy peel properties can be imparted by applying a part coat by hot melt) or by roughening the surface to be sealed.

  According to the cooked food packaging material having the above-described configuration, the outer film is formed so that the cutting assisting means is provided in two strips with a gap in the width direction, and the gripping portion straddles the two cutting assisting means. Therefore, when the gripping portion is gripped and pulled in the length direction, the outer film is cut while being guided by the two stripping auxiliary means. And at least any one of the outer film and the inner film is provided with an easy peel property in a region between at least two cutting assisting means in a portion which becomes a seal line on both ends in the length direction. In the site | part corresponding to a seal line, it will cut | disconnect, peeling from an inner film. As a result, the seal line with increased rigidity is formed so as to intersect the cutting assisting means, and the outer film can be smoothly smoothed even if the wide area is cut (removed) by the two cutting assisting means. Can be cut.

  And, when the outer film is cut over the entire length in the length direction with a width corresponding to the interval between the two stripping assisting means, the outer film remains in a state that is divided into two in the width direction, except for the cut portion. Become. The outer film thus bisected is the remaining portion cut out with a width, so that the overlap with the sheet-like food is reduced, and the portion sandwiched between the outer film and the inner film of the sheet-like food Will be reduced.

  In this state, there is little overlap of the outer film with the sheet-like food, so when the outer film and the inner film are pulled in the width direction, the divided outer film and inner film are smoothly separated without causing a large resistance to the sheet-like food. Then, the inner film is pulled out from between the sheet-like food and the cooked rice processed food. Thereby, it will be in the state which can eat the sheet-like food and the cooked rice processed food integrally without breaking the sheet-like food.

  As one aspect of the present invention, the region where the easy peel property is imparted on the other end side in the length direction is formed wider in the width direction than the region where the easy peel property is imparted on the one end side in the length direction. Preferably it is. In this way, even if the cutting direction of the outer film becomes an unspecified direction and the width that is cut off toward the other end becomes wider, the outer film is peeled off from the inner film in the seal line on the other end side. Can be cut.

  Further, as another aspect of the present invention, the two cutting assisting means are formed with an enlarged portion in which at least a part between the seal lines on both end sides in the length direction is separated from each other and the interval is enlarged. The region to which easy peelability is imparted on the other end side in the direction may be formed wider in the width direction than the interval between the two cutting assisting means in the enlarged portion. If it does in this way, since an outer film will be excised more widely in an expansion part, the resistance with respect to a sheet-like foodstuff when pulling an outer film and an inner film to the width direction can be made smaller. When the outer film is cut (removed) as described above, the outer film is cut (removed) at the maximum width at the enlarged portion. Since the tensile force at this time acts in the length direction, the outer film is enlarged. There is a case where it is cut while being wide from the portion toward the other end. However, in this aspect, the outer film is formed such that the region where the easy peel property is imparted on the other end side in the length direction is formed wider in the width direction than the interval between the two cutting assisting means in the enlarged portion. Even if the width of the cut is wider than the enlarged portion, the outer film can be cut while being peeled from the inner film in the seal line on the other end side.

  As described above, according to the packaged food for cooked rice food according to the present invention, it is possible to achieve an excellent effect that the sheet-like food can be opened smoothly without being broken at the time of opening.

  Hereinafter, a packaged food for cooked rice food according to an embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, the packaging material for processed rice food according to the present embodiment includes processed rice foods such as rice balls and sushi (in this embodiment, rice balls) A, sheeted laver, thin-fried eggs, and tatami mushrooms. The sheet-like food (in this embodiment, laver) B is packaged in a separated state, and as shown in FIG. 2, the outer film 10 configured to be split in the width direction, and the sheet-like food B And an inner film 20 that is configured to be separated in the same direction as the division direction of the outer film 10, so that the outer film 10 and the inner film 20 surround the sheet-like food B It is sealed (see FIG. 3) and is configured to wrap the cooked rice processed food A with the inner film 20 inside (see FIG. 1). In each figure, the hatched area is a sealed part or a sealed part.

  The outer film 10 according to the present embodiment is formed in a substantially rectangular shape in plan view, and is configured to be divisible in a short direction (width direction) perpendicular to the longitudinal direction (length direction). More specifically, the outer film 10 is provided with cutting auxiliary means 100a and 100b for cutting the outer film 10 over the entire length in the length direction. The cutting assisting means 100a, 100b are formed in a linear shape or a strip shape so as to extend in the length direction of the outer film 10, and two strips are provided at intervals in the width direction of the outer film 10.

  Each of the cutting assistance means 100a, 100b is continuously provided over the entire length of the outer film 10, and in this embodiment, a strip-shaped cut tape attached to the outer film 10. It consists of

  The two cut tapes 100a and 100b are provided so as to be symmetric with respect to a center line CL extending in the length direction of the outer film 10, and are separated from each other at least in part in the length direction of the outer film 10. Thus, an enlarged portion 101 is formed with an increased interval.

  When packaging the cooked rice processed food A with the inner film 20 on the inner side, the packaging material 1 for cooked rice processed food according to this embodiment includes the outer film 10 and the inner film 20 in a laminated state in the length direction of the outer film 10. The two ends of the cut tape 100a, 100b are formed at the substantially central position in the length direction on the premise of this packaging form. Are provided.

  That is, in the present embodiment, the two cut tapes 100a and 100b are provided so as to have a minimum interval Lmin at both ends in the length direction of the outer film 10, and the length direction of the outer film 10 from the both ends. The interval is gradually enlarged toward the center of the center, and an enlarged portion 101 having a maximum interval Lmax is formed at the central portion in the length direction. The interval (maximum interval) Lmax of the enlarged portion 101 is a width dimension of the sheet-like food B (a dimension in a direction corresponding to the width direction of the outer film 10 in a state of being interposed between the outer film 10 and the inner film 20). ) To 60% to 110%, and more preferably 75% to 95% of the width dimension of the sheet-like food B.

  On the other hand, the interval (minimum interval) Lmin between the two cut tapes 100a, 100b at both ends in the length direction of the outer film 10 is set to 20% to 55% of the width dimension of the sheet-like food B, and more Preferably, it is set to 30% to 50% of the width dimension of the sheet-like food B.

  The outer film 10 according to the present embodiment is provided with a gripping portion 102 straddling the two cut tapes 100a and 100b at one end in the length direction. That is, the outer film 10 is provided with a pair of cut portions 103, 103 so that two strips of tape 100a, 100b are interposed at one end in the length direction, and the pair of cut portions 103, 103. A gripping portion 102 is formed between them. At both ends in the length direction of the outer film 10, the center portion (between the cut portions 103 and 103 on one end side) is cut out to form outer cutout portions 104 and 104. The outer cutouts 104 and 104 are formed by cutting together the laminated outer film 10 when forming the cutout cutouts 201 and 201 to be described later on the inner film 20.

  As described above, the outer film 10 according to the present embodiment is formed by folding the outer film 10 and the inner film 20 in half and sealing the ends facing each other in the center in the length direction of both side ends. The outer notch portions (V cuts) 105 and 105 for folding are formed by cutting out the portions.

  The inner film 20 is formed in a substantially rectangular shape in plan view like the outer film 10 and is set to be approximately the same size as the outer film 10. The inner film 20 is composed of a single film, and is provided with a linear half-cut 200 that extends over the entire length in the longitudinal direction. Thereby, the inner film 20 is separated (divided) in the width direction by being split by the half cut 200. The half cut 200 is formed to extend linearly at a portion thinner than the surrounding thickness in order to weaken the strength locally. In the present embodiment, the half cut 200 extends over the entire length in the length direction of the inner film 20. It is formed in a straight line. The half cut 200 is formed by melting the film in a line or embossing it so as to be in a non-penetrating state.

  The inner film 20 according to the present embodiment is provided with notches for break (notches) 201 and 201 corresponding to the arrangement of the half cuts 200 at both ends in the length direction. The breaking notches 201 and 201 may be formed so as to be recessed inward (center side of the inner film 20) with respect to an edge that extends straight in the width direction of the inner film 20. It is formed in a circular shape.

  And as above-mentioned, also about this inner film 20, the center part of the length direction of a both-sides edge part assumes the packaging form which folds the outer film 10 and the inner film 20, and seals the edge parts which mutually oppose each other. Are notched to form inner notch portions (V cuts) 202, 202 for folding. In the present embodiment, the inner film 20 and the outer film 10 are set to have substantially the same size, and the inner notch portion 202 for folding of the inner film 20 is premised on the assumption that the outer peripheral ends of the inner film 20 overlap each other. , 202 are set in an arrangement and shape corresponding to the outer cutout portions 105, 105 for folding of the outer film 10.

  And the packaging material 1 for cooked rice processed foods concerning this embodiment laminated | stacked the inner film 20 and the outer film 10 via the sheet-like food B, as shown to Fig.3 (a) and FIG.3 (b). Thus, the outer film 10 and the inner film 20 are sealed so as to form a seal line S surrounding the sheet-like food B. The seal line S includes a pair of side seal lines S1 and S2 formed by sealing both end portions in the width direction of the outer film 10 and the inner film 20 with a predetermined width, and the outer film 10 and the inner film 20. It is composed of a pair of end seal lines S3, S4 sealed at both ends in the length direction, and a space for storing the sheet-like food B by these seal lines S1, S2, S3, S4 (hereinafter referred to as storage space) Defined).

  Of the pair of end seal lines S3, S4, one end seal line S3 on one end side in the length direction of the gripping portion 102 is provided with the gripping portion 102 side and the sheet-like food B. It is formed inside the holding part 102 (the pair of cut parts 103, 103) so as to divide the area (accommodating space) to be formed. Accordingly, one end seal line S3 (seal line S) is formed so as to intersect with the two cut tapes 100a and 100b provided over the entire length of the outer film 10 in the length direction.

  In the present embodiment, the other end seal line S4 on the other end side in the length direction is also formed inside the end edge of the outer film 10. The other end seal line S4 is formed so as to be symmetric with respect to the one end seal line S3 with reference to the approximate center in the length direction. Thereby, also about the other edge part seal line S4 (seal line S), it cross | intersects on the other end side with respect to the two strips of cut tape 100a, 100b provided over the full length of the outer film 10 in the length direction. Is formed.

  In the present embodiment, the movement of the sheet-like food B is regulated between the inner film 20 and the outer film 10, and the sheet-like food B corresponds to the arrangement of the two strips of cut tape 100a, 100b (enlarged portion 101). In order to achieve this, a positioning seal portion S5 is formed by partially sealing a region closer to the accommodation space than the side seal lines S1 and S1 so as to be continuous with the side seal lines S1 and S1.

  A plurality of the positioning seal portions S5 are formed at intervals in the length direction, and the sheet-like food B is positioned from both sides in the width direction. That is, the interval between the tips of the positioning seal portions S5 and S5 protruding from the side seal lines S1 and S2 is set slightly wider than the width of the sheet-like food B, and between the positioning seal portions S5 and S5. The sheet-like food B is located in correspondence with the arrangement (enlarged portion 101) of the two cut tapes 100a and 100b.

  The packaged material 1 for processed cooked rice according to the present embodiment is provided with two cut tapes 100a, 100b extending in the length direction at intervals in the width direction, and a seal line intersecting the two cut tapes 100a, 100b. On the premise that the outer film 10 and the inner film 20 are sealed so as to form S (end seal lines S3, S4), at least one end seal line S3 of the outer film 10 and the inner film 20 , S4 is provided with an easy peel property at least in the region between the two cutting assisting means 100a, 100b.

  If demonstrating it more concretely, the packaging material 1 for processed rice food which concerns on this embodiment will contain the area | region between the two cutting | disconnection assistance means 100a, 100b used as the edge part seal lines S3, S4 of the outer film 10 ( Easy peel properties are imparted to the portion to be sealed. That is, the outer film 10 according to the present embodiment includes the two strip assisting means 100a and 100b, and the easy peel regions Ep1 and Ep2 including the portions that become the end seal lines S3 and S4 are both ends in the length direction. Is provided. The easy peel regions Ep1 and Ep2 have width dimensions L1 and L2 set wider than the minimum interval Lmin between the two strip assisting means 100a and 100b, and end seal lines S3 and S4 in the length direction. It is set wider than the sealing width (the width of the outer film 10 to be sealed in the length direction).

  And in this embodiment, since the two strips of cut tapes 100a and 100b form the enlarged portion 101, the easy peel region Ep1 on one end side where the gripping portion 102 is formed has a width dimension 1 in the width direction. While the width L2 of the outer film 10 in the width direction L2 of the outer film 10 is set to be narrower than the interval Lmax between the cut tapes 100a and 100b of the enlarged portion 101, the cut tape in the enlarged portion 101 is set. It is set wider than the interval Lmax between 100a and 100b.

  Each easy peel area Ep1, Ep2 is formed on the surface facing the inner film 20, and in this embodiment, is formed by part coating. That is, each easy peel area Ep1, Ep2 is formed by printing a resin having excellent peelability. In this embodiment, since the outer film 10 and the inner film 20 are sealed by heat welding, they are part-coated with a resin that exhibits heat peelability but exhibits peelability at room temperature.

  Although details will be described later, in the drawing, a wide easy peel region Ep3 is continuously provided on one end side of the outer film 10 with respect to the easy peel region Ep1 on one end side of the outer film 10 including the end seal line S3. Although it is formed, the wide easy peel region Ep3 on one end side cuts a long original fabric printed integrally with the easy peel regions Ep1 and Ep2 on one end side and the other end side of the outer film 10. Thus, when the outer film 10 is produced, the outer film 10 is formed as an allowance (nige) that allows a displacement of the cutting position Cp with respect to the original fabric (see FIG. 4).

  The packaged food 1 for cooked rice food according to this embodiment has the above-described configuration, and is produced by sequentially cutting a plurality of continuous packaging material 1 for cooked rice processed food into predetermined lengths. . Specifically, as shown in FIG. 4, two strips of tape (continuous body of cut tapes 100 a and 100 b) 100 a ′ and 100 b ′ are formed on the long film Fa set to a width corresponding to the width of the outer film 10. It is stuck continuously in the longitudinal direction. At this time, the two long tapes 100a ′ and 100b ′ are attached to the long film Fa moving in the longitudinal direction while moving in the same direction and passing through a predetermined position while being brought into contact with each other. .

  In the present embodiment, as described above, since the easy peel regions Ep1 and Ep2 are formed on both ends of the outer film 10, two tapes are provided on the original fabric 10 '(long film Fa) of the outer film 10. Part coats are applied at intervals in the longitudinal direction so as to include each portion having a minimum interval of 100a ′ and 100b ′. This part coat is applied by printing on the long film Fa. The part coat has a form in which the easy peel regions Ep1 and Ep2 on one end side and the other end side of the outer film 10 are combined. In the present embodiment, the part coat has a form including the allowable allowance Ep3 described above.

  That is, the long film Fa is set to be longer than the minimum interval between the two tapes 100a ′ and 100b ′ and shorter than the maximum interval between the two tapes 100a ′ and 100b ′ in the short direction perpendicular to the longitudinal direction. A substantially rectangular first region Pa having a long side, and a length that is continuously formed on one end side in the longitudinal direction with respect to the first region Pa, and is set longer than the first region Pa in the lateral direction. A plurality of part coat regions P each having a substantially rectangular second region Pb having sides are formed at intervals in the longitudinal direction.

  And 2nd area | region Pb is a long film with respect to the length (length of the length direction of the outer film 10) of the easy peel area | region Ep2 in which the length of a longitudinal direction is formed in the other end side of the outer film 10 It is set to a length including an allowance (Nige) Ep3 that allows displacement of the cutting position Cp when cutting F. The second region Pb is a portion where the first region Pa which becomes the easy peel region Ep1 on one end side of the outer film 10 is the allowable margin Ep3, and the remaining portion excluding the allowable margin Ep3 is, The cutting position Cp is set at the boundary between the portion that becomes the easy peel region Ep2 on the other end side of the outer film 10 and the portion that becomes the easy peel region Ep2 on the other end side and the allowable allowance Ep3.

  As a result, the long film Fa is cut at the cutting position Cp set in the second area Pb (the cutting position Cp indicated by a two-dot chain line in the figure), so that the first area Pa of the part coat area P is removed. The easy peel region Ep1 on one end side of the film 10 is formed, and the portion excluding the allowance Ep3 in the second region Pb of the part coat region P becomes the easy peel region Ep2 on the other end side of the outer film 10. Yes.

  In this way, the two tapes 100a ′ and 100b ′ are attached to the long film Fa and part coating is performed, whereby the outer film original fabric 10 ′ that is a continuous body of the outer film 10 is obtained. Produced. Since the part coat is applied by printing, for example, information related to a product may be printed together when printing on the long film Fa (outer film 10). That is, of course, printing on the long film Fa may be performed in advance before the two tapes 100a 'and 100b are attached.

  Then, as shown in FIG. 5, the inner film original fabric 20 ′ (continuous body of the inner film 20) in which a half cut 200 ′ extending in the longitudinal direction is formed at the approximate center in the width direction with respect to the long film Fb is removed. It overlaps with the film fabric 10 'through the sheet-like food B. That is, the outer film original fabric 10 ′ (continuous body of the outer film 10) and the inner film raw fabric 20 ′ (continuous body of the inner film 20) are supplied in the longitudinal direction to form a rectangular shape in plan view at predetermined intervals. While supplying the sheet-like food B on either the outer film raw fabric 10 'or the inner film raw fabric 20', the outer film raw fabric 10 'and the inner film so as to sandwich the sheet-shaped food B. The film original fabric 20 'is overlaid.

  At this time, the sheet-like food B formed in a rectangular shape in plan view is aligned with the longitudinal direction of the outer film original fabric 10 'and the inner film original fabric 20' (long film Fa, Fb), The outer film raw fabric so that the substantially central position in the longitudinal direction corresponds to the position where the distance between the two tapes 100a ′, 100b ′ is maximized (position where the expanded portion 101 of the cooked rice food packaging material 1 is located). Supplied on either 10 'or the inner film original fabric 20'.

  Then, since the sheet-like food B is interposed at predetermined intervals in the longitudinal direction of the outer film original fabric 10 ′ and the inner film original fabric 20 ′, the outer film is surrounded so as to surround each sheet-like food B. The original fabric 10 'and the inner film original fabric 20' are sealed. That is, both ends in the width direction of the overlapped outer film original fabric 10 ′ and inner film original fabric 20 ′ are sealed with a predetermined width, and regions (part coats) on both sides in the longitudinal direction of the sheet-like food B In the region P), the band-like regions extending in the width direction are sealed. As a result, seal lines S1 ′ and S2 ′ having a predetermined width are formed at both ends extending in the longitudinal direction of the raw film 10 ′ for the outer film and the raw film 20 ′ for the inner film, and a belt-like seal line extending in the width direction. A raw material 1 ′ for packaging material in which two S3 ′ and S4 ′ are formed in the longitudinal direction between the sheet-like foods B is produced. Of the two seal lines S3 ′ and S4 ′ arranged in the length direction between the sheet-like foods B, one seal line S3 ′ passes through the first region Pa, and the other seal line S4 ′ The two regions Pb are formed so as to pass through a portion excluding the allowance Ep3.

  In the present embodiment, the cooked rice food packaging material 1 is continuously produced from the produced packaging material stock 1 '. That is, generally, when a long packaging material 1 'is produced, the packaging material 1' is once wound into a roll, and the packaging material 1 'is drawn from the roll. The packaging material 1 for cooked rice processed food is prepared by appropriately cutting, but in this embodiment, after sealing the outer film original fabric 10 'and the inner film raw fabric 20' (the original packaging material 1 ') After that, the raw material 1 ′ for packaging material is continuously cut between the two seal lines S3 ′ and S4 ′ formed between the sheet-like foods B and B, and the packaging material 1 for cooked rice processed food is obtained. They are made sequentially.

  In the present embodiment, the packaging material web 1 ′ (the outer film web 10 ′ and the inner film web 20) is formed between the two seal lines S3 ′ and S4 ′ (the second area Pb of the part coat area P). When cutting '), the outer cutouts 104 and 104, the outer cutouts 105 and 105 for folding, the cutouts 201 and 201 for breaking, and the inner cutouts 202 and 202 for folding are formed together for processed rice foods. The packaging material 1 is produced sequentially and sequentially. In addition, since the cutting parts 103 and 103 are provided only in the outer film 10 in the packaging material 1 for cooked rice food according to the present embodiment, the cutting parts 103 and 103 are formed of the outer film original fabric 10 '. Before the inner film original fabric 20 ′ is overlaid, it is provided as a cut in the outer film original fabric 10 ′. As with the notches 104, 105, 201, 202, the packaging material original 1 A cut may also be made when cutting ', and the cut portions 103 may be provided in both the outer film 10 and the inner film 20.

  Next, the usage aspect of the packaging material 1 for cooked rice processed foods is demonstrated. In order to wrap the cooked rice processed food A with the packaged food 1 for cooked rice with the above configuration, first, as shown in FIG. 6A, the cooked rice processed food (triangle rice ball in this embodiment) A is formed on the inner film 20. 6 and bake the cooked rice food packaging material 1 (the outer film 10 and the inner film 20) in the length direction as shown in FIG. 6B. In this state, the region corresponding to the enlarged portion 101 (the region between the outer notch portions for folding 105 and 105 and the region between the inner notch portions for folding 202 and 202) stands up corresponding to the thickness of the cooked rice processed food A Then, both sides of the region are in a state of being opposed to each other through the cooked rice processed food A.

  Thereafter, as shown in FIG. 6 (c), the two side ends facing each other in the width direction are folded to the other side by being folded in two, and overlapped with the side end on the other side. The portions are sealed, and seal lines extending in the length direction are formed on both sides in the width direction.

  In this state, both ends in the length direction form an opening, and both ends of the center position in the length direction of the outer film 10 and the inner film 20 (the outer notch portions 105 and 105 for folding and the inner notch portion 202 for folding). , 202 corresponds to a triangular projecting piece by folding the side end. The cooked rice packaging material 1 according to the present embodiment has the outer notch portions 105 and 105 for folding and the inner notch portion 202 for folding at both end portions of the center position in the length direction of the outer film 10 and the inner film 20. , 202 is provided, so that a projecting piece having a good appearance can be formed without performing unnecessary folding on the portion.

  And as shown in FIG.6 (d), the both ends of the length direction of the outer film 10 and the inner film 20 which formed the opening so that the holding part 102 may be held inside the holding part 102 (the cooked rice processed food) A) The opening is closed by sealing in the width direction in the form of a line or a band. Preferably, the regions including the easy peel regions Ep1 and Ep2 of the outer film 10 are sealed, more preferably, the end seal lines S3 and S4 on both ends are sealed. That is, in the case where the opening is closed by thermal welding, not only the ends of the inner film 20 facing each other by folding, but also the outer film 10 and the inner film 20 are heated and welded. It seals so that the part in which easy peel area | region Ep1, Ep2 was formed may be included. Thereby, the state in which the inner film 20 is interposed between the sheet-like food B and the cooked rice processed food A without the outer film 10 and the inner film 20 being sealed at the portion where the easy peel property is not imparted, That is, the sheet-like food B and the cooked rice processed food A are packaged in a separated state.

  Then, in order to open the packaged rice processed food 1 in which the cooked rice processed food A is packaged in the above-described manner, as shown in FIG. 7A, the holding film 102 is held and the outer film 10 is pulled in the length direction. The outer film 10 is cut in the length direction. At this time, the outer film 10 is cut (broken) while being guided by the two cut tapes 100a and 100b. In one end seal line S3 (easy peel region Ep1), the outer film 10 is the inner film. It will be cut while peeling from 20. The same applies to the other seal line S4 (easy peel region Ep2). Thereby, when cut | disconnecting the outer film 10, the cutting | disconnection is cut | disconnected smoothly, without inhibiting. As a result, as shown in FIG. 7B, the central region in the width direction of the outer film 10 is cut out over the entire length in the length direction. That is, the outer film 10 corresponds to the manner in which the cut tapes 100a and 100b are attached, and the part to be cut is enlarged toward the center position side in the length direction (folded part by bi-folding). It opens to the maximum in the corresponding part. Thereby, the part by which the sheet-like food B was pinched | interposed into the outer film 10 and the inner film 20 will be in the state reduced.

  And as shown in FIG.7 (c), when the both sides of the length direction both ends (overlapping both ends) of the outer film 10 and the inner film 20 are pulled in the width direction, the tensile force will be the length of the inner film 20 It acts on the cutout portions 201 and 201 for breaking provided at both ends in the vertical direction, and acts on the half cut 200 that reaches the cutout portions 201 and 201 for breakage. In this case, the half cut 200 forms a groove and stress (force) acts intensively. Further, since the thickness of the portion corresponding to the half cut 200 is thinner than the surrounding thickness and is weak, The pulling force concentrated on the notches 201 and 201 acts on the half cut 200 in a concentrated manner and the portion is torn.

  As a result, when the inner film 20 is cut (broken) over the entire length in the length direction, both the outer film 10 and the inner film 20 are bisected in the width direction, as shown in FIG. Thus, the inner film 20 interposed between the cooked rice processed food A and the sheet food B is pulled out so that the cooked rice processed food A and the sheet food B are integrated.

  In the present embodiment, as described above, the outer film 10 is cut (removed) in the length direction so that the portion where the sheet-like food B is sandwiched between the outer film 10 and the inner film 20 is reduced. Therefore, when the inner film 20 is pulled out, resistance is hardly generated between the outer film 10 and the sheet-like food B, and the sheet-like food B can be opened integrally with the cooked rice A without breaking the sheet-like food B. it can.

  As described above, according to the packaged food 1 for cooked rice food according to the present embodiment, the outer film 10 is provided with two strips of the cut tapes 100a and 100b at intervals in the width direction, and the grip portion 102. Is formed so as to straddle the two strips of tape 100a, 100b, and the regions Ep1, Ep2 between at least the two strips of tape 100a, 100b in the portions that become the seal lines S (S3, S4) on both ends in the lengthwise direction. Since an easy peel property is imparted, there is a seal line S (S3) with increased rigidity, and even if a wide area is cut with two cut tapes 100a, 100b, it can be cut smoothly. it can. Moreover, since the overlap of the outer film 10 divided into two at the time of opening with respect to the sheet-like food B can be reduced, the resistance between the sheet-like food B and the outer film 10 can be reduced, and the sheet-like food B can be smoothly smoothed. And cooked rice processed food A can be integrated.

  In particular, the two cut tapes 100a and 100b according to the present embodiment form the enlarged portion 101 that is spaced apart and enlarged in at least a part of the length direction, so that the outer film 10 is bisected. At this time, the film can be cut wider, and the resistance to the sheet-like food B when the outer film 10 and the inner film 20 are pulled in the width direction can be further reduced.

  Since the region Ep2 to which easy peelability is imparted on the other end side in the length direction is formed longer (wide) in the width direction than the interval Lmax between the two cut tapes 100a and 100b in the enlarged portion 101. Even if the outer film 10 is cut while being widened from the enlarged portion 101 toward the other end side, the outer film 10 can be cut while being peeled from the inner film 20 in the seal line S (S4) on the other end side. it can.

  In addition, the packaging material for cooked rice processed foods of this invention is not limited to the said embodiment, Of course, a various change can be added in the range which does not deviate from the summary of this invention.

  In the above embodiment, the easy peel regions Ep1 and Ep2 are formed on the outer film 10, but the present invention is not limited to this.
