Description

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

  Traditional rice balls with seaweed sold at convenience stores, etc. are packaged with a packaging material containing seaweed between the outer sheet and the inner sheet to prevent the seaweed from getting wet when in contact with the rice balls. By doing so, the rice balls and seaweed were wrapped so that they would not come into direct contact.

  As shown in FIG. 4, the packaging material 50 includes outer sheets 52 and 2 made of a single heat-sealable film (film that can be welded by heating) in order to sandwich and store a sheet-like seaweed 51. An inner sheet 53 composed of a single heat-sealable film is provided. The outer sheet 52 is formed in, for example, a substantially rectangular shape that can wrap a rice ball. The outer sheet 52 has a cut tape 54 attached to the center line in the width direction of the inner side surface (the inner sheet side surface). By pulling the cut tape 54, the outer sheet 52 is torn and divided in the width direction. It is configured to be.

  On the other hand, when the outer sheet 52 and the inner sheet 53 are overlapped, the two films constituting the inner sheet 53 have an inner end of one film and an inner side of the other film on the center line in the width direction of the outer sheet 52. The end portions are overlapped on the inside and outside and are arranged so as to be easily separated in the width direction of the inner sheet 53.

  The outer sheet 52 and the inner sheet 53 are stacked so that the seaweed 51 is sandwiched therebetween, and the peripheral portion excluding the central portion in the width direction is welded by a heat seal 55 or the like to form the packaging material 50. ing.

  As shown in FIG. 5A, the packaging material 50 configured in this way has a rice ball 56 placed on the inner sheet 53 side, and one end of the cut tape 54 is positioned at one corner of the rice ball 56. Thus, the packaging material 50 is folded in half, and folded along with the shape of the rice ball 56 together with the seaweed 51 accommodated therein, thereby packaging the rice ball 56 as shown in FIG. At this time, the rice ball 56 is packaged so that only the inner sheet 53 is interposed between the seaweed 51.

  When the end of the cut tape 54 protruding from the corner on the top side of the rice ball 56 packaged in this way is picked and pulled, the outer sheet 52 of the packaging material 50 that wraps the rice ball 56 is torn and is divided. When the ears 58 and 58 that are folded in two and project from the corners on the bottom side of the rice ball 56 and partially wrapped with the packaging material 50 are pulled in the separation direction, the inner sheet 53 is formed together therewith. The two films are pulled out from between the rice balls 56 and the nori 51 in the above-mentioned separation direction so that the nori 51 wraps the rice balls 56 (a state in which the rice balls 56 and the nori 51 are combined). Will be able to.

JP 2003-128124 A (paragraphs 0031 to 0033)

  By the way, in order to give a high-quality appearance to the package body in which the rice balls 56 are packaged, it is conceivable to provide a paper quality sheet such as Japanese paper on the outer sheet 52. For example, it is conceivable to form the outer sheet 52 by sticking a paper sheet to the outer surface of the heat-sealable film.

  However, since the paper sheet does not have heat sealability, when the outer sheet 52 is configured by sticking the paper sheet to the outer surface of the heat sealable film, the packaging material 50 is folded and the rice balls 56 are packaged. It is impossible to heat seal to keep the state. That is, when the packaging material 50 is bent to the state shown in FIG. 5B, the inner sheet 53 (with heat sealability) and the paper quality sheet (without heat sealability) come into contact with each other, so that heat sealing is performed. However, they cannot be heat sealed because they do not weld.

  Here, in the case of rice balls with seaweed sold at convenience stores, various information such as raw materials, manufacturers, sales prices, etc. are shown on the side of the packaging material 50 folded and overlapped as shown in FIG. 5 (B). Often the label is printed. Therefore, in order to reliably apply the label to the surface, it is desirable to temporarily fix the packaging material 50 by the heat sealing prior to label application. If this temporary fixing cannot be performed, for example, the operator must apply the label while holding the packaging material 50 by hand, so that a label application failure occurs or the efficiency of the application operation decreases.

  Therefore, Patent Document 1 proposes that an outer sheet is formed by sandwiching a paper sheet from outside and inside with a heat-sealable film. By using the outer sheet having this configuration, the heat-sealable film and the inner sheet exposed on the outer surface of the outer sheet can be heat-sealed.

  However, when the paper sheet is sandwiched between the heat-sealable films in this way to form the outer sheet, two heat-sealable films are required, which increases the manufacturing cost of the packaging material.

  Then, this invention makes it a subject to provide the packaging material for cooked rice processed foods which can be heat-sealed even if it provides a paper-type sheet | seat in an outer sheet | seat, and can suppress the raise of manufacturing cost in view of the said problem.

  The packaged food for cooked rice food of the present invention comprises an outer sheet formed so as to be separable in the width direction, and an inner sheet formed so as to be separated in the same direction as the outer sheet, with the sheet-like food being stacked. In the packaged food for cooked rice food, in which the outer sheet and the inner sheet are sealed so as to surround the sheet-like food, the outer sheet has a paper sheet adhered to the outer surface of the base film made of a heat-sealable film. The inner sheet is composed of a heat-sealable film, and the outer sheet is the base film without the paper sheet adhered to the portion that is heat-sealed when packaging cooked rice food Has a sealable portion exposed on the outer surface.

  According to the above configuration, since the base film made of the heat-sealable film is not pasted with a paper sheet and has a sealable part exposed on the outer surface, the outer sheet and the inner sheet are attached to the sealable part. Can be heat sealed. And since the number of constituent points of the outer sheet can be reduced while giving the appearance of the package a high-class appearance, the configuration of the outer sheet can be simplified.

  And the packaging material for cooked rice processed foods of this invention WHEREIN: It is preferable that the said sealable part was provided in one edge part of the longitudinal direction of the said outer sheet | seat.

  Moreover, the said outer sheet shall have the part which the said base film was exposed to the outer side surface in the other edge part of a longitudinal direction other than the said sealable part without the said paper sheet | seat being stuck. Is preferred.

  According to the preferable configuration, the portion where the base film is exposed on the outer surface at the other end in the longitudinal direction is matched with the portion that is the starting point for tearing the outer sheet when eating cooked rice processed food. The starting portion can be made of only the base film, and the outer sheet can be easily torn.

  And the packaging material for cooked rice processed foods of this invention WHEREIN: The said paper quality sheet has a width dimension smaller than the said base film, and the outer sheet has the outer surface of the said base film exposed in the width direction both ends. It is preferable.

  According to the preferable configuration, since only the base film is provided at both ends in the width direction of the outer sheet, each of the outer sheet and the inner sheet is heat-sealed when including the width direction both ends of each sheet. A large difference does not occur in the temperature at which the heat-sealable film of the sheet melts, and deformation (curl) of the packaging material due to the difference in melting temperature is unlikely to occur.

  According to the present invention, by having the sealable portion, heat sealing can be performed even if a paper sheet is provided on the outer sheet. And since the structure of an outer sheet | seat can be simplified, the raise of manufacturing cost can be suppressed.

It is a disassembled perspective view of the packaging material for cooked rice processed food which concerns on one Embodiment of this invention. The packaging material for processed rice foods is shown, (A) is a plan view, and (B) is a bottom view. It is a back view of the state which packed the cooked rice processed food of the packaging material for cooked rice processed foods. It is sectional drawing which showed the conventional packaging material for cooked rice processed foods. (A) (B) is explanatory drawing at the time of packaging a cooked rice processed food with the packaging material for cooked rice processed food of FIG.

  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. In the following description, “packaged food for cooked rice” and “packaged food for processed rice” are simply referred to as “packaging” and “packaging”. In addition, the expression “inside and outside” in the following description is based on a direction determined based on the case where the cooked rice processed food is packaged.

  As shown in FIG. 1, the packaging material 1 includes a substantially rectangular outer sheet 10 having a size capable of enclosing a rice cooked food R that has a triangular shape such as a rice ball in a folded state, and a rice cooked food R. 2, the outer sheet 10 and the inner sheet 20 are sealed so as to surround the sheet-like food 3, and are shown in FIG. 2. It has been made. In addition, as the cooked rice processed food R, rice balls and the like are included in addition to various rice balls. In addition to the sheet-like laver, the sheet-like food 3 includes sheet-like kelp, tatami mats, and the like.

  The outer sheet 10 is composed of two members, a base film 11 and a paper sheet 12 attached to the outer surface of the base film 11. The paper sheet 12 is attached to the base film 11 by a known method such as laminating.

  The base film 11 is made of a heat-sealable film made of polyethylene or polypropylene, and has a shape in which notches 111 are provided at four corners of a rectangular shape in plan view. Then, the base film 11 is provided with an opening gripping portion 112 that functions as a knob 41 (described later) of the package 4, and is cut by a cutting means 113 provided along the longitudinal direction (that is, a pinch). It is configured such that it can be divided in the width direction (by pulling and holding the holding portion 112). The dividing means 113 is provided to define the direction and width in which the base film 11 is divided. Specifically, a cut tape 113a is used.

  The cut tape 113a is affixed to the inner surface of the base film 11 along the longitudinal direction. In addition, one end of the cut tape 113 a is provided at a position corresponding to the grip portion 112. Further, the cut tape 113a has a linear shape or a strip shape so as to extend along the longitudinal direction of the base film 11, and in this embodiment, the two strip tapes 113a, 113a are the center line in the width direction of the base film 11. Are provided in parallel at symmetrical positions. The cut tape 113a is not limited to the one provided in parallel to the center line in the width direction of the base film 11 as in the present embodiment, and may be provided in a curved manner.

  The grip portion 112 is provided on one end side in the longitudinal direction of the base film 11. Specifically, a pair of incisions 112a and 112a extending in the longitudinal direction from the longitudinal end edge 114 are formed in the outer sheet 10 so as to be separated from each other in the width direction, and the pair of incisions 112a and 112a In the meantime, the holding portion 112 is defined. In addition, the pair of cut portions 112a and 112a are formed on the outer side in the width direction with respect to the two cut tapes 113a and 113a in parallel at symmetrical positions across the center line in the width direction of the base film 11.

  As shown in FIG. 1, the paper sheet 12 has a substantially H shape in plan view in which cutout portions 121 are provided at four corners of a rectangle and end cutout portions 122 are further provided. As this paper sheet 12, for example, rayon paper formed in the form of Japanese paper (having a carded pattern) can be used, but the present invention is not limited to this, and various sheet-like materials belonging to paper can be used. Since the paper sheet 12 is exposed to the outside in the state of the package 4, a product name and a cautionary note are printed here.

  In the present embodiment, the end notch portion 122 includes one end side notch portion 122a cut out in the longitudinal direction from one longitudinal edge 123a of the paper sheet 12, and the other cut out in the longitudinal direction from the other longitudinal edge 123b. It is comprised from the end side notch part 122b. The end notches 122 are formed symmetrically with respect to the center line in the width direction of the paper quality sheet 12 and have a substantially rectangular shape in plan view with rounded corners on the inner side of the paper quality sheet 12. Further, the other end side cutout portion 122b is formed to have a larger longitudinal dimension than the one end side cutout portion 122a. Due to the end notches 122, the outer sheet 10 has portions where the paper film 12 is not adhered and the base film 11 is exposed on the outer side surface at both ends in the longitudinal direction.

  The end notch 122 forms a through-hole by punching a die or the like in the material of the paper sheet 12 continuously supplied in the longitudinal direction, and the width of the material is reduced by passing through the through-hole. It is formed by cutting in the direction. The difference in the longitudinal dimension between the one end side cutout portion 122a and the other end side cutout portion 122b can be caused during the cutting.

  By providing the one-end-side cutout portion 122a as described above, as shown in FIG. 2A, an easy-cut portion 10a in which the base film 11 is exposed on the outer surface of the outer sheet 10 is formed. In the easy cut portion 10a, the gripping portion 112 and the cut portions 112a and 112a and a part of the cut tapes 113a and 113a are also exposed on the outer surface. Therefore, the outer sheet 10 can be easily torn with the holding portion 112 (the knob 41 of the package 4). In addition, since the paper sheet 12 is not provided in the easy-cut portion 10a, the easy-cut portion 10a is flexible, and the gripping portion 112 can easily follow the shape of the package 4 as shown in FIG. Moreover, since the holding part 112 is flexible, it is easy to pick the holding part 112.

  On the other hand, by providing the other end side cutout portion 122b, the sealable portion 10b in which the base film 11 is exposed to the outer side surface is formed as in the case of the one end side cutout portion 122a. As shown in FIG. 3, the sealable portion 10 b coincides with a portion (a portion to which the point seal PS is applied) that is heat-sealed when packaging the cooked rice processed food R. Therefore, the heat-sealable films (more specifically, the outer sheet 10 and the inner sheet 20) overlapped at the sealable portion 10b can be heat-sealed. By providing the other end side cutout 122b as described above, the outer sheet is formed outside the outer sheet that is sandwiched between the outer side and the inner side by a heat-sealable film, as in the related art (related to Patent Document 1). The number of constituent members of the sheet 10 can be reduced, and the outer sheet 10 provided with the paper sheet 12 can contribute to the suppression of an increase in manufacturing cost.

  By the way, as shown in FIG. 2A, the paper sheet 12 has a width dimension smaller than that of the base film 11. And when sticking the paper quality sheet 12 to the base film 11 and forming the outer sheet | seat 10, both are overlaid so that each width direction center line may correspond. Thereby, the outer surface of the base film 11 is exposed at both ends in the width direction. That is, only the heat-sealable film is provided at both ends in the width direction of the outer sheet 10. Here, if the paper sheet 12 is provided to both ends in the width direction of the outer sheet 10, the outer sheet 10 and the inner sheet 20 are heat-sealed including both ends in the width direction of the sheets 10 and 20. At this time, there may be a large difference in the temperature at which the heat-sealable films of the outer sheet 10 and the inner sheet 20 are melted. As a result, the packaging material 1 is deformed (curled) and is bulky when the packaging materials 1 are stacked. In addition, since it becomes difficult to stack a plurality of packaging materials 1, it becomes a hindrance when transporting the packaging material 1. In addition, when the cooked rice processed food R is packaged, there may be a problem that the packaging material 1 is difficult to bend. On the other hand, when only the heat-sealable film is provided at both ends in the width direction of the outer sheet 10 as in this embodiment, the outer sheet 10 and the inner sheet 20 are connected to each of the sheets 10 and 20. Even when heat-sealing including both ends in the width direction, since a large difference in the temperature at which each heat-sealable film melts is unlikely to occur, the occurrence of deformation (curl) can be prevented, and the above-described problems are unlikely to occur.

  In the paper sheet 12, a dividing means 124 is provided at a portion overlapping the dividing means 113 (cut tape 113 a) of the base film 11 in plan view. The dividing means 124 is configured so that the paper sheet 12 can also be divided in the width direction when the dividing means 113 of the base film 11 is divided. The dividing means 124 is provided to define the direction and width in which the base film 11 is divided. Specifically, a perforation 124a is used.

  The perforation 124 a is provided along the longitudinal direction of the paper sheet 12. In the present embodiment, as shown in FIG. 2A, the two perforations 124a, 124a are aligned with the widthwise outer ends of the cut tapes 113a, 113a of the base film 11 or cut. The tapes 113a and 113a are wider than the widths of the outer ends of the tapes 113a and 113a, and are formed in parallel at symmetrical positions across the center line in the width direction of the paper sheet 12. In addition, this parting means 124 is not restricted to the perforation 124a, It can implement with various forms, such as a cut tape and a half cut. When the cut tape 113a is provided with a curve, the perforation 124a is also provided with a curve.

  Therefore, the outer sheet 10 formed by attaching the paper sheet 12 provided with the dividing means 124 to the base film 11 provided with the dividing means 113 pulls the holding portion 112 provided on the base film 11 and pulls the base film 11. The dividing means 113 and the dividing means 124 for the paper sheet 12 are divided so as to be divided in the width direction.

  Next, as shown in FIG. 1, the inner sheet 20 is composed of two films 21 and 22 that partially overlap each other. Specifically, it is composed of a heat-sealable film made of polyethylene or polypropylene, and notches 211 and 221 are formed at portions located at the four corners when the films 21 and 22 are overlapped with the outer sheet 10. The provided rectangular shape in plan view. When the outer sheets 10 and the inner sheet 20 are overlapped with each other through the sheet-like food 3, the respective films 21 and 22 have an inner end portion of one film 21 and the other film 22 on the center line in the width direction of the outer sheet 10. The inner end portion of the inner sheet 20 overlaps with the inside and the outside, and is arranged so as to be easily separated in the width direction of the inner sheet 20.

  In addition to the above, the inner sheet 20 may be composed of a single heat-sealable film that can be separated in the width direction. In that case, perforations, half cuts, and the like are formed along the longitudinal direction so that they can be easily separated in the width direction.

  Next, the packaging material 1 is formed by sealing the outer sheet 10 and the inner sheet 20 so as to surround the sheet-like food 3. As shown in FIGS. 2A and 2B, the packaging material 1 has a seal portion S1 that surrounds the sheet-like food 3 and extends along the longitudinal direction, and a seal portion S2 that extends along the width direction. Each seal part S1, S2 is formed by heat sealing the outer sheet 10 and the inner sheet 20. The seal portion S1 is provided with a non-seal portion S1a so as to allow ventilation in the width direction. Of the seal portion S2, the width direction seal portion S2a on the side where the knob 41 is formed (one end in the longitudinal direction) is provided in two rows, and the width direction seal portion on the side where the knob 41 is not present (the other end in the longitudinal direction). S2b is provided in a row. The width-direction seal portion S2 is not overlapped with the dividing means 113 of the base film 11 and the dividing means 124 of the paper sheet 12, so that the separation in the width direction of the packaging material 1 is not hindered. Yes.

  Hereinafter, the package 4 using the packaging material 1 configured as described above will be described. First, as shown in FIG. 1, the triangular cooked rice processed food R is placed on the inner sheet 20 of the packaging material 1. Next, the packaging material 1 is folded in the longitudinal direction, and the back side of the cooked rice processed food R is covered with the left half of the packaging material 1 shown in the figure, and the front side is covered with the right half.

  Here, the cooked rice processed food R has a triangular shape, whereas the packaging material 1 has a substantially rectangular shape. Therefore, both ends of the packaging material 1 in the width direction remain in the folded state. Therefore, this surplus portion is folded back so as to be superimposed on the packaging material 1 covering the back surface of the cooked rice processed food R to obtain the triangular shape shown in FIG.

  In the state shown in FIG. 3, the sealable portion 10 b is located on the back side of the package 4. In this sealable portion 10b, since the paper sheet 12 having no heat sealability is not provided, heat sealing can be performed between the outer sheet 10 and the inner sheet 20. Therefore, as shown, a point seal PS that is a spot-like heat seal can be applied. Thereby, the shape of the packaging body 4 made into the triangular shape can be maintained, and it becomes easy to stick a label on the back side of the packaging body 4. The shape of the point seal PS is not limited to the circular shape as shown in the figure, and may be various shapes such as an oval shape, an oval shape, a polygonal shape, a linear shape, and the point seal PS applied to the back side of the package 4. Also, the number is not limited to two as shown in the figure, but can be three or more, or one large point seal PS can be applied so as to straddle both ends in the width direction of the packaging material 1.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
