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 a technique in which an outer film and an inner film are sealed so as to surround the seaweed in a state where the sheet and the inner sheet are overlapped (see Patent Document 1).

  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.

JP 2010-215292 A JP 2007-252316 A

  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 prevent 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 splittable in the other direction perpendicular to one direction, and an inner sheet configured of a pair of separation portions that can be separated 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 joint part formed by joining a pair of separation parts so as to be separable at positions closer to the center than both ends in the other direction, and the joint part is a first joint extending in one direction. And a second joint formed so as to taper from the first joint toward the one end side of the inner sheet in the other direction.

  According to such a configuration, since the pair of separation portions constituting the inner sheet are joined by the joining portion at positions closer to the center side than both ends of the inner sheet in the other direction, the moisture of the cooked rice processed food and the inner sheet It is possible to prevent entry into the space between the outer sheets (that is, the space for storing the sheet-like food).

  Specifically, when the inner sheet is composed of a pair of sheet pieces that partially overlap each other as in the past, when the cooked rice processed food is packaged, a gap is generated between the pair of sheet pieces. The moisture of the cooked rice processed food enters the space between the inner sheet and the outer sheet (the space for storing the sheet-like food). However, as in the present invention, the pair of separation portions are joined by the joining portion, so that such a gap does not occur in the joining portion. For this reason, it is possible to prevent the moisture of the cooked rice processed food from entering the space between the inner sheet and the outer sheet (the space for storing the sheet-like food).

  Moreover, a junction part is comprised from the 1st junction part extended in one direction, and the 2nd junction part formed so that it may taper toward the one end side of the inner sheet | seat in another direction from this 1st junction part. Thus, the pair of separation portions can be easily separated, and the separation of the pair of separation portions can be started from an arbitrary position.

  Specifically, by applying a pulling force to the inner sheet in the other direction, such a force is concentrated on the second joint portion rather than the first joint portion. Thereby, since joining of a pair of separation part is released from the 2nd joining part as a starting point, separation of a pair of separation parts (namely, division of an inner sheet) can be performed easily. Moreover, since the force which pulls an inner sheet to another direction concentrates on a 2nd junction part, joining of a pair of isolation | separation part can be released from a 2nd junction part. That is, by arbitrarily setting the position where the second joint portion is provided on the inner sheet, the separation of the pair of separation portions can be started from an arbitrary position (position of the second joint portion).

  It is preferable that the joining portion is formed over the entire area between both ends of the inner sheet in one direction.

  According to such a configuration, the joint portion is formed over the entire area between both ends of the inner sheet in one direction, so that a gap that occurs between the pair of sheet pieces is generated in the inner sheet as in the related art. There is no. For this reason, it can prevent more reliably that the moisture of cooked rice processed food penetrate | invades into the space (space which accommodates a sheet-like foodstuff) between an inner sheet | seat and an outer sheet | seat.

  Preferably, the joint portion includes a pair of first joint portions, and the second joint portion is formed between the pair of first joint portions.

  According to such a configuration, the second joint portion is formed between the pair of first joint portions, so that the pair of separation portions starts from the second joint portion and the pair of first portions starts from the second joint portion. It will be unraveled towards the joint. Thereby, a pair of separation | separation part (namely, division | segmentation of an inner sheet | seat) can be performed more easily.

  It is preferable that the second joint portion is formed such that a tip portion located on one end side of the inner sheet in the other direction forms an acute angle.

  According to such a configuration, when the force that pulls in the other direction is applied to the inner sheet by forming the tip end portion of the second joint portion at an acute angle, the force is applied to the second joint portion. Since it concentrates on the front-end | tip part, joining of a pair of isolation | separation part in a 2nd junction part can be released more easily.

  As described above, according to the present invention, it is possible to prevent the sheet-like food contained between the outer sheet and the inner sheet from getting wet.

  As shown in FIG. 1, the packaging material 1 according to the present embodiment includes an inner sheet 2 in contact with the cooked rice processed food A and an outer sheet 3 superimposed on the inner sheet 2. And the inner sheet | seat 2 and the outer sheet | seat 3 are the end parts sealed so that the sheet-like food B may be enclosed in the state piled up via the sheet-like food B wound around the cooked rice processed food A. As shown in FIG. Thereby, the packaging material 1 can package the cooked rice processed food A in a state where the cooked rice processed food A and the sheet-shaped food B are separated. 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.

  The outer sheet 3 includes an outer sheet main body 3a having a size capable of wrapping the cooked rice processed food A, and a pair of cut tapes 3b and 3b stacked on the outer sheet main body 3a. The outer sheet body 3a is formed so that one direction (hereinafter also referred to as a first direction) is a longitudinal direction (in the present embodiment, in a rectangular shape), and the other direction (hereinafter referred to as a second direction) orthogonal to the first direction. The width direction is also indicated. On the other hand, the cut tape 3b is arranged to extend in the first direction at the center of the outer sheet main body 3a in the second direction.

  The outer sheet 3 includes a pair of cut portions 3c and 3c formed at one end of the outer sheet main body 3a in the first direction so as to extend in the first direction. The pair of cut portions 3c, 3c are formed at intervals in the second direction, and each end portion of the pair of cut tapes 3b, 3b is configured to be positioned between the pair of cut portions 3c, 3c. The Further, the pair of cut portions 3c, 3c are formed such that one end portions thereof are in contact with the edge of the outer sheet main body 3a. Thereby, the area | region between a pair of notch parts 3c and 3c in the outer sheet | seat 3 is isolate | separated from another area | region. Thereby, the knob | pick part 3d which can be picked with a finger | toe etc. in the area | region between a pair of notch parts 3c and 3c is formed.

  And it is possible to cut | disconnect the outer sheet | seat 3 along a 1st direction from each other end part of a pair of notch parts 3c and 3c by picking the knob | pick part 3d and pulling along a 1st direction. Become. And since the strip | belt-shaped area | region between a pair of cutting lines starting from each other end part of a pair of notch parts 3c and 3c is isolate | separated from another area | region by the outer sheet | seat 3 being cut | disconnected, an outer sheet | seat 3 can be divided in the second direction.

  The inner sheet 2 is formed in substantially the same shape as the outer sheet 3 (specifically, a rectangular shape having the first direction as a longitudinal direction). Further, the inner sheet 2 is configured to be divided in the same direction as the outer sheet 3, that is, in the second direction. Specifically, the inner sheet 2 is composed of a pair of separation portions 2a and 2b configured to be separable in the second direction, and is configured to be divided by separating the pair of separation portions 2a and 2b. Is done.

  As shown in FIG. 2, one separation portion (hereinafter, also referred to as a first separation portion) 2 a is formed in a rectangular shape whose first direction is the longitudinal direction. The first separation portion 2a has one end portion in the second direction (hereinafter also referred to as an inner end portion) 2a1 positioned on the center side of the inner sheet 2 in the second direction, and the other end portion in the second direction (hereinafter, 2a2 (also referred to as an outer end) constitutes one end (hereinafter also referred to as an inner sheet first side end) 21 of the inner sheet 2 in the second direction.

  The other separation part (hereinafter also referred to as a second separation part) 2b is formed in a rectangular shape having a first direction as a longitudinal direction. The second separation portion 2b has one end portion in the second direction (hereinafter also referred to as an inner end portion) 2b1 positioned on the center side of the inner sheet 2 in the second direction, and the other end portion in the second direction (hereinafter, The second end 2b2 of the inner sheet 2 in the second direction (hereinafter also referred to as the inner sheet second side end) 22 constitutes the second end 2b2. The second separating portion 2b includes a folded portion 2b3 formed by folding the inner end portion 2b1 toward the outer end portion 2b2 side. The folded portion 2b3 is formed to extend in the first direction (specifically, along). As a result, the region on the outer end 2b2 side with respect to the inner end 2b1 and the inner end 2b1 overlap each other in the second separating portion 2b, and the edge of the second separating portion 2b constituting the inner end 2b1 is the folded portion. It will be located in the outer side edge part 2b2 side rather than 2b3.

  Further, the inner sheet 2 includes a superposed portion 2c formed by overlapping a part of the pair of separating portions 2a and 2b. The overlapping portion 2c is formed so as to extend in the first direction (specifically, along the center) of the inner sheet 2 in the second direction. Further, the overlapping portion 2c is formed between the joint portion 2d and the folded portion 2b3 in the second direction. The joint 2d and the folded portion 2b3 will be described later.

  The overlapping portion 2c is formed by overlapping the inner end portions 2a1, 2b1 of the pair of separating portions 2a, 2b. Specifically, the overlapping portion 2c is formed by the inner end 2a1 of the first separating portion 2a overlapping the folded inner end 2b1 of the second separating portion 2b. That is, in the overlapping portion 2c, one surface of the pair of separating portions 2a and 2b constituting the inner end portions 2a1 and 2b1 faces each other. Moreover, in the superposition | polymerization part 2c, it will be in the state which the edges of a pair of isolation | separation part 2a, 2b which comprise each inner side edge part 2a1, 2b1 overlapped along the 1st direction.

  Further, the pair of separating portions 2a and 2b are joined to be separable at positions closer to the center than both ends of the inner sheet 2 in the second direction. That is, the inner sheet 2 includes a joining portion 2d formed by joining a pair of separating portions 2a and 2b so as to be separable. In the present embodiment, the joint 2d is formed in a linear shape. Specifically, linear joining is performed by joining edges (specifically, edges extending in the first direction) constituting the inner end portions 2a1 and 2b1 of the pair of separating portions 2a and 2b. Part 2d is formed. Moreover, the joining part 2d is formed over the entire region between both ends of the inner sheet 2 in the first direction.

  Further, the joint portion 2d has a first joint portion 2e extending in the first direction, and is tapered from the first joint portion 2e toward the inner sheet first side end portion 21 side (specifically, V It is comprised from the 2nd junction part 2f formed. In the present embodiment, the joint portion 2d includes a pair of first joint portions 2e, and a second joint portion 2f is formed between the pair of first joint portions 2e and 2e. Specifically, the second joint portion 2f is formed at the center portion of the inner sheet 2 in the first direction, and a pair of first joints is formed from the second joint portion 2f toward both end portions of the inner sheet 2 in the first direction. One joint portion 2e, 2e is formed.

  The first joint 2e is formed in a straight line so as to extend in the first direction (specifically along), one end is connected to the second joint 2f, and the other end is in the first direction. It is formed in contact with the edge of the inner sheet 2. The second joint portion 2f projects from the first joint portion 2e to the folded portion 2b3 side of the second separation portion 2b (that is, the outer end portion 2a2 side of the first separation portion 2a) (specifically, 1 junction 2e and folded portion 2b3). The second joining portion 2f is formed such that a tip portion (that is, an end portion on the tapering side) 2g located on the inner sheet first side end portion 21 side forms an acute angle. Moreover, the 2nd junction part 2f connects the 1st junction part 2e to each of the base end parts 2h and 2h located in the inner sheet 2nd side edge part 22 side. Moreover, the 2nd junction part 2f is formed by notching a part (specifically center part) of the superposition | polymerization part 2c.

  The method for forming the inner sheet 2 is not particularly limited. For example, as shown in FIG. 3A, the material sheet 4 for forming the inner sheet 2 is folded in two along the first direction. As shown in FIG. 3 (b), a pair of separation portions 2a and 2b are formed by fusing at a planned position 4a for forming the joint portion 2d, and edges of the pair of separation portions 2a and 2b are formed by fusing. The two are welded together to form the joint 2d. And the inner sheet | seat 2 as shown in FIG. 2 is formed by folding up the 2nd separation part 2b by making the folding line 4b extended in a 1st direction into an axis line.

  Then, by applying a force to the inner sheet 2 in a direction in which the inner sheet first side end 21 and the inner sheet second side end 22 are separated from each other, a force that peels off the joint 2d is applied to the joint 2d. Will join. As a result, the bonding of the bonding portion 2d is released (specifically, the bonding is released from the second bonding portion 2f toward the pair of first bonding portions 2e and 2e), and the pair of separation portions 2a and 2b is The inner sheet 2 is separated in the second direction.

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

  That is, since the pair of separation parts 2a and 2b constituting the inner sheet 2 are joined by the joining part 2d at positions closer to the center than the both end parts 21 and 22 of the inner sheet 2 in the second direction, the cooked rice processed food A Can be prevented from entering the space between the inner sheet 2 and the outer sheet 3 (that is, the space for storing the sheet-like food B).

Specifically, since the pair of separation portions 2a and 2b are joined by the joint portion 2d, no gap is generated between the pair of separation portions 2a and 2b in the joint portion 2d. For this reason, 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 space for storing the sheet-like food B).
Moreover, the 1st junction part 2e extended in a 1st direction, and the 2nd junction part 2f formed so that it may taper toward the one end part 21 side of the inner sheet 2 in this 2nd direction from this 1st junction part 2e, By forming the joining portion 2d from the inner sheet 2, the inner sheet 2 can be easily separated.

  Specifically, by applying a pulling force to the inner sheet 2 in the second direction, the force is concentrated on the second bonding portion 2f rather than the first bonding portion 2e. Thereby, since the joining of the pair of separating portions 2a and 2b is released from the second joining portion 2f, the pair of separating portions 2a and 2b can be easily separated (that is, the inner sheet 2 is divided). .

  Moreover, the joint part 2d is formed over the entire region between both ends of the inner sheet 2 in the first direction, so that the moisture of the cooked rice processed food A is a space between the inner sheet 2 and the outer sheet 3 (sheet-like food). It is possible to more reliably prevent entry into the space (B).

  Further, since the second joint 2f is formed between the pair of first joints 2e and 2e, the pair of separation parts 2a and 2b is joined from the second joint 2f starting from the second joint 2f. It will be solved toward a pair of 1st junction parts 2e and 2e. Thereby, separation of the pair of separation portions 2a and 2b (that is, division of the inner sheet 2) can be performed more easily.

  Moreover, when the force which pulls to a 2nd direction with respect to the inner sheet 2 is added by forming the front-end | tip part of the 2nd junction part 2f at an acute angle, such a force is the 2nd junction part 2f. Since it concentrates on the front-end | tip part, joining of a pair of isolation | separation part 2a, 2b in the 2nd junction part 2f can be more easily released.
