Description

  The present invention relates to a packaging sheet for packaging a rice cake formed by sandwiching a sheet-like food between an inner film and an outer film, and a packaging rice cake in which the rice cake is packaged by the packaging sheet.

  So-called packaged rice chunks in which rice chunks such as triangular rice balls are wrapped with a packaging sheet are sold at convenience stores and the like. As a packaging sheet, there is a triple sheet having a sheet-like nori sandwiched between an outer film and an inner film. For example, in Patent Document 1, the outer film is formed by intermittently forming incisions such as perforations crossing in the width direction at the center in the longitudinal direction, and these incisions are covered with a strip-shaped cover film piece from the inside. The inner film has two inner film pieces stacked on the cut of the outer film. And an outer film and an inner film are heat-welded along the periphery vicinity of a sheet-like nori.

Japanese Patent No. 5890116

  Since the intermittent cuts of the outer film are exposed to the outside, if the cuts are all broken and connected, there is a possibility that the packaging of the packaged rice lump will be unwound.

  The present invention clarifies a packaging sheet and a packaged rice lump in which intermittent cuts of the outer film are not exposed to the outside.

The packaging sheet of the present invention is
An outer film having a plurality of intermittent cuts extending in the width direction at a substantially central portion in the longitudinal direction;
An inner film that can be divided at a position substantially opposite to the intermittent cut of the outer film;
A sheet-like food disposed between the outer film and the inner film;
With
The outer film and the inner film are joined by a heat welding part on the outer peripheral side of the sheet-like food,
A packaging sheet,
On the outer surface of the outer film, there is a peeling sheet that covers the intermittent cuts from the outside,
The peeling sheet has a zipper portion between a pair of cutting lines formed substantially parallel to the intermittent cuts of the outer film, and has a sticking portion on both sides of the zipper portion,
The zipper portion is opposed to the intermittent cuts in the outer film;
The sticking part is bonded to the outer film.

  The cutting line may be an intermittent cut.

  It is desirable that the zipper portion has a display indicating an opening direction.

The packaged rice lump of the present invention is
A packaged rice cake in which a flat shaped rice cake is packaged with the packaging sheet described above,
The zipper part is opposed to the peripheral surface of the rice lump.

  Since the packaging sheet of the present invention peels off intermittent cuts of the outer film and covers them from the outside with the sheet as described above, the cuts are not exposed to the outside. Moreover, even if the cut of the outer film is connected, the cut is blocked from the outside, so that intrusion of moisture or the like can be prevented. Therefore, also about the packaged rice lump which packaged the rice lump with the packaging sheet of this invention, penetration | invasion of moisture etc. can be prevented with a peeling sheet, and the dry state of a sheet-like foodstuff can be maintained. In addition, the packaged rice lump of the present invention is removed by pulling the zipper part of the peeled sheet, and then the intermittent cut of the exposed outer film is directed downward, and the upper part of the packaged rice lump is picked to bring the rice lump downward. By extruding, the outer film is cut by connecting the cuts, and the lump falls in a state of being wrapped in the sheet-like food by its own weight, so that the packaging can be easily unwound.

FIG. 1 is an exploded perspective view of a packaging sheet according to an embodiment of the present invention. FIG. 2 is a cross-sectional view along the longitudinal direction of the packaging sheet. FIG. 3 is a plan view of the packaging sheet as seen from the outside. FIG. 4 is a back view of the peeled sheet as viewed from the outer film side. FIG. 5 is a perspective view of a packaged rice cake in which the rice cake is packaged with the packaging sheet of the present invention. FIG. 6 is a perspective view in the middle of pulling out the zipper portion from the peeling sheet. FIG. 7 shows a state where the rice cake is falling from the packaging sheet. FIG. 8 is a perspective view of a packaged rice cake obtained by packaging the rice cake in a bag shape.

  Hereinafter, the packaging sheet 10 and the packaged rice lump 70 of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 1 and 2, the packaging sheet 10 is formed by sandwiching a sheet-like food 40 between a rectangular transparent outer film 20 and an inner film 30. In FIG. 2, the outer film 20, the inner film 30, and the sheet-like food 40 are drawn so that only the line and the peeled sheet 50 have a thickness, but this is for easy understanding of the invention. Moreover, although the zipper part 53 shown with the code | symbol 53 of the peeling sheet 50 is drawn away from the outer film 20, this exaggeratesly shows that the zipper part 53 is not adhere | attached on the outer film 20. In practice, the zipper portion 53 and the outer film 20 are in contact with each other.

  The outer film 20 is a vertically long film in this embodiment, and a plurality of intermittent cuts 23 and 23 extending in the width direction are formed in a perforated shape at a substantially central portion in the longitudinal direction. And as will be described later, the outer film 20 receives a force in a direction substantially orthogonal to the cuts 23 and 23, so that the connection portion between the cuts 23 and 23 is broken and the cuts 23 and 23 are connected and cut. It has become. The outer film 20 can have a length in the longitudinal direction of about 24 cm and a length in the width direction of about 14 cm. In the illustrated embodiment, the outer film 20 has chamfered corners, but may have a rectangular shape or the like.

  The inner film 30 is composed of two inner film pieces 31 and 31 having the same shape, and the inner edges of the inner film 30 overlap each other by about 1 cm at positions facing the notches 23 and 23 of the outer film 20. The inner film pieces 31, 31 are formed so as to have substantially the same shape as the outer film 20 when they are stacked as described above. That is, in the drawing, the corners of the inner film pieces 31 and 31 are chamfered. The inner film 30 can also be formed of a single film as long as the inner film 30 can be divided at a position substantially opposite to the notches 23 and 23 of the outer film 20. For example, like the outer film 20, an intermittent cut may be formed, and the cut may be blocked with a strip-shaped cover film from the inner surface side. Moreover, it is good also as forming a linear dent in the inner film 30, and being able to parting.

  As the inner film 30, it is desirable to use a film made of a material to which rice grains do not easily adhere. For example, as the inner film 30 (inner film pieces 31, 31), an embossed film in which concave portions and convex portions are uniformly distributed can be used. By using the embossed film, the detachability from the rice lump 60 can be enhanced, and the rice grains can be prevented from adhering to the inner film 30.

  In the embodiment, the sheet-like food 40 is a sheet-like seaweed. In addition, the sheet-like food 40 will not be specifically limited if it is thin foods, such as what formed the rag tangle in the sheet form, and the thinly stretched rice cake. The sheet-like food 40 can have a length of about 19 cm in the longitudinal direction and a length of about 9 cm in the width direction. The sheet-like food 40 may have a substantially rectangular shape, but as shown in the figure, a rectangular shape with chamfered corners or a shape with a rounded chamfered end in the longitudinal direction is used. By using a thing, the rice lump 60 can be easily dropped from the packaging sheet 10 as described later.

  Then, the sheet-like food 40 is placed at a substantially central position of the outer film 20, and the inner film pieces 31, 31 constituting the inner film 30 are placed thereon, and the outer film 20 is surrounded so as to surround the sheet-like food 40. The outer film 20 and the inner film 30 are linearly heat-welded 11 along the periphery. In addition, heat welding is not given to the overlapping part of the inner film pieces 31 and 31.

  Moreover, it is desirable to apply the thermal welding 12 that prevents the sheet-like food 40 from being displaced near one end or both ends in the longitudinal direction of the sheet-like food 40.

  As shown in FIGS. 2 and 3, a peeling sheet 50 is attached to the outer surface of the outer film 20. FIG. 4 is a view of the peeling sheet 50 as viewed from the back side that is the outer film 20 side. The peeling sheet 50 is attached so as to cover the intermittent cuts 23 and 23 of the outer film 20 from the outside. The peeling sheet 50 can be made of, for example, paper such as art paper, foil paper, Japanese paper, high-quality paper, mirror-coated paper, a resin film, synthetic paper, or the like. The maximum width of the peeling sheet 50 is approximately the same as that of the rice lump 60 and the maximum length is the width of the outer film 20. In the illustrated embodiment, the corner of the peeling sheet 50 is chamfered, but it may be substantially rectangular.

  In more detail, the peeling sheet 50 has a pair of intermittent cutting lines 51 and 51 at intervals substantially parallel to the cuts 23 and 23. For example, the cutting lines 51 and 51 can exemplify intermittent cutting. The cut may be linear as shown, or may be tilted so that the cut angles are symmetrical to each other. Moreover, these combinations may be sufficient. Note that the cutting lines 51 and 51 may have, for example, a configuration in which the wall thickness is reduced as long as the cutting lines 51 and 51 can be cut when the zipper portion 53 is pulled.

  The portion sandwiched between the cutting lines 51 and 51 constitutes a zipper portion 53 that is gripped when unpacking the packaged rice lump 70. The both sides of the zipper part 53 are sticking parts 55 and 55. Adhesive portions 55, 55 are provided with adhesive layers 56, 56 indicated by hatching in FIG. The zipper part 53 does not need to be provided with an adhesive layer, but may be provided with an extremely weak adhesive layer. In order to make the zipper part 53 easy to grasp, it is preferable that the cutting lines 51 and 51 be about 7 mm to 12 mm.

  As shown in FIGS. 2 and 3, the peeling sheet 50 is bonded to the outer film 20 by attaching the bonding portions 55 and 55 so that the zipper portion 53 faces the cuts 23 and 23 of the outer film 20. Attached to. Thereby, the notches 23 and 23 of the outer film 20 are covered with the zipper part 53, and are hidden without being exposed to the outside.

  In addition, as shown in FIG. 3, it is desirable to print the display 58 like the arrow which shows an opening direction on the zipper part 53 of the peeling sheet 50 etc. FIG. If the cutting lines 51 and 51 can cut the zipper part 53 from both directions, the display 58 is one or both ends of the zipper part 53, and if the cutting lines 51 and 51 can cut the zipper part 53 from only one direction, The display 58 may be printed only on one end of the zipper portion 53.

  The peeling sheet 50 may be attached to the outer film 20 before packaging the mass of rice 60, but it is of course possible to adhere to the outer film 20 after packaging the mass of rice 60.

  As shown in FIG. 5, the lump 60 is packaged by the packaging sheet 10 having the above configuration. The rice lump 60 is a lump that is flattened by hardening white rice or rice. Preferably, both side surfaces are substantially parallel, and the both side surfaces are connected to each other by a flat or curved peripheral surface. The rice lump 60 may be partially or entirely sprinkled with sprinkled food such as sesame, placed with ingredients, or sandwiched with ingredients.

  The illustrated rice lump 60 is a triangular rice ball having a height of about 7 cm and a width of about 4 cm, but can also be a round rice ball or a rectangular rice ball. In order to make the rice cake 60 slide well from the inner film 30 and drop it, it is desirable that the sides and corners of the rice cake 60 be chamfered. The chamfering can be exemplified by round chamfering. R is preferably 5 mm or more, and more preferably approximately 8 mm.

  The rice lump 60 having the above configuration is placed on the packaging sheet 10 with the inner film 30 side facing upward. In the case of a triangular rice ball, the rice lump 60 is one surface of the peripheral surface, in the figure (the bottom surface is the intermittent cuts 23 and 23 of the outer film 20 when the packaging sheet 10 is folded, that is, the inner film piece. 31 and 31 are placed so as to face each other.

  Note that the packaging sheet 10 may be folded in advance in a U shape to sandwich the rice lump 60.

  The packaged rice cake 70 can be obtained by placing the rice cake 60 on the packaging sheet 10, wrapping the rice cake 60, and sealing the end of the packaging sheet 10 with fastening means (not shown). The fastening means can be a tape or a heat-welded label, or a label that describes the date of manufacture or contents.

  In the resulting packaged rice lump 70, intermittent cuts 23 and 23 of the outer film 20 are peeled off from the outside and blocked by the sheet 50, so that moisture or the like can enter the interior of the packaging sheet 10 from the cuts 23 and 23. Therefore, the sheet-like food 40 can be kept in a crisp state. Moreover, by making the peeling sheet 50 substantially coincide with the width of the packaged rice lump 70, the packaged rice lump 70 can be sat satisfactorily when the peeled sheet 50 is displayed with the bottom surface as the bottom surface.

  Moreover, since the cuts 23 and 23 are not exposed, the packaged rice lump 70 of the present invention can prevent intrusion of moisture or the like due to the presence of the outer peeling sheet 50 even if the cuts are broken and connected.

  The packaged rice lump having the above configuration can be unpacked in the following manner.

  First, as shown in FIG. 6, one end of the zipper part 53 of the peeling sheet 50 is grasped and pulled in the arrow A direction. Thereby, as for the peeling sheet 50, the cutting lines 51 and 51 are cut | disconnected, and the zipper part 53 and the sticking parts 55 and 55 are cut | disconnected separately. And after removing the zipper part 53, the cuts 23 and 23 of the exposed outer film 20 are turned downward, and the top of the packaged rice lump 70 is lightly picked, so that the lump 60 is moved downward as shown in FIG. When moved, the cuts 23 and 23 are connected, the outer film 20 is cut, and the outer film 20 is opened 25.

  By keeping the opening 25 facing down as it is, the rice lump 60 falls in the direction of the arrow B while pulling out the sheet-like food 40 from between the outer film 20 and the inner film 30 due to its own weight. As the lump 60 is dropped, the inner film 30 also opens when the inner film pieces 31 and 31 are overlapped.

  At this time, if the rice lump 60 does not fall smoothly due to its own weight, the finger holding the top end of the packaged rice lump is lowered as it is so that the rice lump 60 moves downward, and the lump 60 is pushed down. Just shake gently downward.

  When the lump 60 is completely detached from the packaging sheet 10, the lump 60 is taken out from the packaging sheet 10 with the sheet-like food 40 directly covered.

  The lump 60 that has been unwrapped and covered with the sheet-like food 40 can be eaten by winding the end of the sheet-like food 40 around the lump 60.

  In addition, as mentioned above, by chamfering the sides and corners of the lump 60, the contact resistance with the inner film 30 can be reduced, and the lump 60 can be smoothly dropped without being out of shape. be able to.

  Furthermore, as above-mentioned, the corner | angular part of the sheet-like food 40 is pinched | interposed into the folded part of the outer film 20 and the inner film 30 by chamfering the corner | angular part of the sheet-like food 40, or chamfering the edge part roundly. Therefore, the sheet-like food 40 can be smoothly pulled out from between the outer film 20 and the inner film 30 without being torn.

  In the above description, dimensions and desirable shapes are illustrated as appropriate for easy understanding of the description, but it is obvious that the present invention is not limited to the above dimensions and shapes. For example, what is necessary is just to produce the magnitude | size of the packaging sheet 10 according to the magnitude | size of the rice lump 60. FIG.

  FIG. 8 shows an embodiment in which the lump 60 is packaged by forming the packaging sheet 10 into a bag shape. In this case as well, the packaging can be opened in the same manner.

  The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. In addition, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope described in the claims.
