  However, rice balls sold on the market are stored separately in the packaging film as described above, with dried seaweed and rice balls made of cooked rice. Since it is necessary to take out the seaweed, change the hand and wrap the seaweed around the rice ball, the user is required to perform a cumbersome operation, and if the seaweed cannot be removed due to an operational error, In particular, when the user is a handicapped person or the like, there is a problem that a case where the seaweed cannot be successfully wrapped around the rice ball by the above operation is likely to occur. In addition, the rice ball itself is usually firmly held to prevent the rice balls from collapsing, and there is a problem that the texture when the user eats is not good.

  Similarly, it is difficult to take out seaweed even if it is wrapped in advance or a rice ball without seaweed is used.

  Therefore, the present invention solves the problems of the above-mentioned conventional rice balls, so that anyone can take out the rice balls without failure by simple operation, and at the same time take out the seaweed and roll the rice balls with rice. It is an object of the present invention to provide a rice ball packaging film and a rice ball that can obtain a rice ball that is easy to eat without being firmly gripped.

  In order to achieve the above object, the present invention accommodates laver in a hollow portion formed between a pair of separable exterior films and a pair of separably polymerized interior films. The present invention basically provides a rice ball packaging film in which the outer peripheral edge portions of the film and the interior film are integrally joined, and finger insertion holes are formed in the outer peripheral edge portion. The pair of exterior films and the pair of interior films are each polymerized so as to be peelable at the center, and the finger insertion hole is formed to be a through hole when a rice ball is packaged.

  Also, a pair of exterior films that are formed in a rectangular shape in plan view and polymerized so as to be peelable at the central portion, and a pair of interior films that are formed in a rectangular shape in plan view and polymerized so as to be peelable in the central portion The laver is housed in a hollow portion formed between them, and the outer peripheral edge of the exterior film and the interior film are joined together, and the longitudinal center along the outer periphery of the exterior film and the interior film joined together is integrated. There is provided a rice ball packaging film in which a recess is formed at a position, and a finger insertion hole is formed at a symmetrical position between the outer peripheral edge of the exterior film and the interior film across the recess. The finger insertion holes are formed on both left and right sides in the longitudinal direction of the outer peripheral edge, and the overlapped portion of the exterior film and the overlapped portion of the interior film are each detachably joined by an adhesive layer or have adhesive strength. The outer peripheral edge of the exterior film and the outer peripheral edge of the interior film are joined together by a plurality of different adhesive layers, or the entire periphery of the outer peripheral edge is joined, or the polymerized portion of the exterior film and the interior film It is joined except for the overlapping part. And the force which opens a pair of exterior film and a pair of interior film is transmitted via a finger penetration hole.

  And the rice ball which mounted and packaged the rice ball on the interior film of the above-mentioned film for packaging rice balls is provided. Specifically, a rice ball is placed on the interior film of the above-described rice ball packaging film, and the lower portion of the rice ball packaging film is folded upward and fixed to wrap the rice ball, or the rice ball packaging. The rice ball is packaged by folding the lower portion of the film for use upward and then bending the both upper edge portions of the rice ball packaging film inward to fix it to the exterior film. And when eating, it pulls in the left-right direction through a finger insertion hole, removes an exterior film and an interior film, and uses for the edible by winding the appearing seaweed around a rice ball.

  Also provided is a rice ball packaging film in which a finger insertion hole is formed in the outer peripheral edge of a pair of films polymerized in a separable manner. The pair of films are polymerized so as to be peelable at the central portion, and the concave portion is formed at a substantially central position in the longitudinal direction along the outer peripheral edge of the film formed in a rectangular shape in plan view so as to be peelable at the central portion. The finger insertion hole is formed in the symmetrical position of the film with the concave portion interposed therebetween. The finger insertion holes are formed so as to be through holes when the rice balls are packaged, and the finger insertion holes are formed on both the left and right sides of the outer peripheral edge in the longitudinal direction. The superposed portions of the pair of films are bonded to each other by an adhesive layer so as to be peeled off, and are bonded by a plurality of adhesive layers having different adhesive forces. And the force which opens a pair of film is transmitted via a finger penetration hole.

  Furthermore, the rice ball packaged by placing the rice ball on the interior film of the above-mentioned rice ball packaging film, placing the rice ball on the rice ball packaging film, and bending the lower part of the rice ball packaging film upward The rice balls are wrapped or fixed on the rice ball packaging film, and the lower portions of the rice ball packaging film are bent upward, and then the upper edge portions of the rice ball packaging film. A rice ball packaged with rice balls is provided by folding and fixing the inside. And when eating, the rice ball packaging film is removed by pulling in the left-right direction through the finger insertion hole, and the onigiri that appears is used for food. Rice balls are pre-wrapped with nori.

  According to the rice ball packaging film and rice ball according to the present invention, the user puts a fingertip into a finger insertion hole formed in the outer peripheral edge of the packaging film and pulls the outer peripheral edge by a certain length in the left-right direction. Since the overlapped portion of the film and the interior film peels left and right, and the seaweed is exposed in a state of covering the whole surface of the rice ball together with the rice ball, the user can wrap the seaweed that appears on the rice ball and use it for food. Alternatively, when the user puts a fingertip into a finger insertion hole formed in the outer peripheral edge of the packaging film and pulls the outer peripheral edge by a certain length in the left-right direction, the overlapping portion of the rice ball packaging film peels left and right The rice balls wrapped with nori can be exposed and removed. Therefore, no cumbersome operation is required for the user, and even if it is an infant, the elderly, or a handicapped person, the rice ball can be easily taken out without failure, and the seaweed can be wrapped around at the same time as taking it out. Since rice balls made of cooked rice do not need to be held firmly, the onigiri itself has a high texture and can be used for eating out to obtain a rice ball that is easy to eat.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a rice ball packaging film and a rice ball according to the present invention will be described below with reference to the drawings. 1 is an internal view showing a first embodiment of a rice ball packaging film 1 according to the present invention, FIG. 2 is an external view of the exterior film, and FIG. 3 is an internal view showing a state where the rice ball 11 is placed in FIG. 4 is a cross-sectional view taken along line AA in FIG. In the figure, 1 is a film for packaging rice balls according to the present invention, and 2 shown in FIG. 2 is an exterior film formed in a rectangular shape in plan view. The exterior film 2 is polymerized with a constant width so that the open ends of the pair of rectangular films 2a and 2b can be separated at the center in the longitudinal direction. 2c is an overlapping portion of the rectangular films 2a and 2b. As shown in FIG. 4, the open end of one rectangular film 2a is bent inward with a predetermined width, and the other rectangular film 2b The bent portion is overlaid on the open end.

  The overlapping portion 2c is bonded by the adhesive layer 7a over the entire length in the longitudinal direction, and the open end portion side is partially bonded by the adhesive layer 8a. The adhesive layer 7a has a relatively weak adhesive force and does not require a strong force for peeling, whereas the adhesive layer 8a has a relatively strong adhesive force and requires a strong force for peeling. That is, the adhesive force between the two is in the relationship of adhesive layer 7a <adhesive layer 8a. This is to prevent the adhesive layer 7a from peeling even when a strong force is applied during carrying or handling by the adhesive layer 8a, and the adhesive layer 7a facilitates peeling. Therefore, it is appropriate to form the adhesive layer 8a at the open end of the overlapping portion 2c that faces a finger insertion hole 5a described later.

  And the recessed part 4a is formed in the longitudinal direction approximate center position of the both ends of the left-right direction of the exterior film 2. As shown in FIG. Finger insertion holes 5a into which the user's fingertips can be inserted are formed at symmetrical positions of the outer peripheral edge portions 6a on the left and right in the longitudinal direction of the exterior film 2 with the recess 4a interposed therebetween. In the illustrated example, four finger insertion holes 5a are formed in total, four on the outer peripheral edge 6a on the left and right in the longitudinal direction. The finger insertion hole 5a may have any shape as long as the fingertip of the user can be inserted and pulled, and the size is not limited.

  Reference numeral 3 shown in FIG. 1 is an interior film formed in a rectangular shape in plan view, and has the same shape as the exterior film 2. The interior film 3 is polymerized with a constant width so that the open ends of the pair of rectangular films 3a and 3b can be separated at the center in the longitudinal direction. 3c is an overlapping portion of the rectangular films 3a and 3b. As shown in FIG. 4, the open end of one rectangular film 3a is bent inward with a predetermined width, and the other rectangular film 3b The bent portion is overlaid on the open end.

  The overlapping portion 3c is bonded by the adhesive layer 7b over the entire length in the longitudinal direction, and is partially bonded by the adhesive layer 8b. The adhesive layer 7b has a relatively weak adhesive force and does not require a strong force for peeling, whereas the adhesive layer 8b has a relatively strong adhesive force and requires a strong force for peeling. That is, the adhesive force between the two is in the relationship of adhesive layer 7b <adhesive layer 8b. This is to prevent the adhesive layer 7b from peeling even when a strong force is applied during carrying or handling by the adhesive layer 8b, and the adhesive layer 7b facilitates peeling. Therefore, it is appropriate to form the adhesive layer 8b at the open end of the overlapping portion 3c that faces a finger insertion hole 5b described later.

  And the recessed part 4b is formed in the longitudinal direction approximate center position of the both ends of the left-right direction of the interior film 3. FIG. Finger insertion holes 5b into which the user's fingertips can be inserted are formed at symmetrical positions of the outer peripheral edge portions 6b on the left and right in the longitudinal direction of the interior film 3 with the recess 4b interposed therebetween. In the illustrated example, four finger insertion holes 5b are formed in total, four on the outer peripheral edge 6b on the left and right in the longitudinal direction. The finger insertion hole 5b may have any shape as long as the user's fingertip can be inserted and pulled, and the size is not limited. Therefore, the exterior film 2 and the interior film 3 have the same outer shape.

  After placing the rectangular laver 10 on the exterior film 2, the interior film 3 is overlapped, and the laver 10 is stored in the hollow portion 9 formed between the exterior film 2 and the interior film 3. Thus, the outer peripheral edge 6a of the exterior film 2 and the outer peripheral edge 6b of the inner film 3 are integrally bonded and fixed using means such as heat sealing. 1 and 3, the hatched portion of the cross is shown as a heat-sealed portion. Thereby, the outer periphery 6 of the rice ball packaging film 1 is formed (the outer periphery 6a + the outer periphery 6b = the outer periphery 6). And the recessed part 4a of the exterior film 2 and the recessed part 4b of the interior film 3 overlap in the approximate center position of the left-right direction of the longitudinal direction, and the recessed part 4 of the rice ball packaging film 1 is formed (recessed part 4a + recessed part 4b = recessed part 4). ). Further, the finger insertion hole 5a of the exterior film 2 and the finger insertion hole 5b of the interior film 3 are overlapped at a symmetrical position with the center line O sandwiched between the outer peripheral edge portion 6 and the fingertip of the user can be inserted. A finger insertion hole 5 is formed in the rice ball packaging film 1 (finger insertion hole 5a + finger insertion hole 5b = finger insertion hole 5). In the illustrated example, a total of eight finger insertion holes 5 are formed with four left and right finger insertion holes 5 symmetrically in the vertical and horizontal directions across the center line O. The force for opening the pair of exterior films 2 and the pair of interior films 3 can be transmitted through the finger insertion holes 5.

  The procedure for packaging rice balls using the rice ball packaging film 1 will be described below. First, as shown in FIG. 3, the rice ball packaging film 1 is placed vertically on a base, and a triangular rice ball is used with the center line O as a reference. 11 is placed, and the lower part of the rice ball packaging film 1 is folded upward with the center line O as a folding line to cover the entire surface of the rice ball 11. At this time, the laver 10 previously stored in the hollow portion 9 formed between the exterior film 2 and the interior film 3 is set at a position that covers the entire front and back of the rice ball 11. The rice balls are not limited to a triangular shape, and may be any shape such as a quadrangular shape or a bowl shape. FIG. 5 is a plan view showing a state where the lower part of the rice ball packaging film 1 is folded upward and the open ends on the left and right sides and the upper side are overlapped, and the lower part of the rice ball packaging film 1 is superimposed on the upper part. As a result, a downward projecting piece 1c is generated by the inner part of the recess 4 formed at a substantially central position on the left and right in the longitudinal direction of the rice ball packaging film 1. Therefore, the projecting piece 1c is folded outward and appropriately applied to the exterior film 2. Glue by means of.

  Next, as shown in FIG. 6, with the lower part of the rice ball packaging film 1 overlapped with the upper part, the left and right and upper three open ends are overlapped and joined and fixed by appropriate means such as heat sealing. Next, the upper end and the lower end of the onigiri packaging film 1 superposed on each other are bent inward according to the shape of the rice ball 11 and temporarily fixed to the exterior film 2 by the heat seal portion 12. As will be described in detail later, the strength of the heat seal portion 12 is set so that it can be easily detached from the exterior film 2 when the user grasps the outer peripheral edge portion 6 and gently pulls it on both sides. 7 is a bottom view when the rice ball 11 is packaged in the rice ball packaging film 1, and FIG. 8 is a central longitudinal sectional view of FIG. In this illustrated example, the rice ball 11 is packaged so that the lower end 1b and the upper end 1a of the rice ball packaging film overlap. Note that folding the upper end 1a and the lower end 1b of the overlaid rice ball packaging film 1 in accordance with the shape of the rice ball 11 may be omitted, and the lower portion of the rice ball packaging film 1 may be It may be omitted that the right and left and upper three open ends are overlapped and bonded and fixed by appropriate means such as heat sealing in a state of being bent into two, and appropriate portions may be bonded and fixed partially. .
