Description

  The present invention relates to a packaged food in which cooked rice processed food such as a triangular rice ball or a round rice ball is packaged in a long package, and further relates to a sheet fixing device and a sheet fixing method for fixing a plurality of overlapping sheets.

  Conventionally, as a packaged food in which cooked rice processed food is packaged in a package, a packaged food in which a triangular rice ball 200 is packaged in a triangle with a rectangular package 201 as shown in FIG. 13 is known ( For example, Patent Document 1). The package 201 has an inner sheet that is separable in the width direction, and an outer sheet that is stacked on the inner sheet via sheet-like food (for example, laver or kelp) and is separable in the same direction as the inner sheet. The inner sheet and the outer sheet are formed to be sealed with each other so as to surround the sheet-like food.

  13A, the front side of the rice ball 200 is covered with the lower half side of the packaging body 201 with the inner sheet inside, and the back side of the rice ball 200 is covered with the upper half side of the packaging body 201. (Arrow J in FIG. 13A). Thereafter, both corners on the lower half side of the package 201 are folded (arrows K and K in FIG. 13A) and overlapped on the upper half side portion covering the back side of the rice ball 200.

Furthermore, since the inner sheet and the outer sheet in the package 201 have heat weldability as a whole, when the overlapping portion where the package 201 overlaps is heated from above, as shown in FIG. Each part is heat-welded (fixed) to form a packaged food. In general, the packaged food is attached with a label 203 for displaying product information so as to cover the portion 202 to be thermally welded, that is, the fixing portion 202.

  However, with respect to the package 201 in which each sheet has heat weldability as a whole, by heating the overlapping portion where each part of the package 201 overlaps from above, the parts of each package 201 are thermally welded. For packages that have a surface that prevents heat welding (parts that do not have heat weldability, that is, parts that are non-heat-weldable) on the surface side, the overlapping part is heated from above. Even in this case, it may not be possible to thermally weld the parts of the package.

  For example, a package provided with a portion (for example, a paper sheet) that inhibits thermal welding on the surface side of the outer sheet is folded in the same manner as in FIG. 13 and overlapped at substantially the same positions as the fixing portions 202 and 202 in FIG. Even if the part is heated from above, the overlapping part is overlapped with the part of the inner sheet having heat-weldability on the part that inhibits the heat-weldability of the outer sheet, that is, the heat-seal of the outer sheet. Since the site | part which inhibits property and the site | part of the inner sheet | seat which has heat welding property are contacting, heat welding cannot be performed between these each site | part. Therefore, it cannot fix by heat welding between each site | part of the package in an overlap part.

  Therefore, in view of such circumstances, the present invention provides an overlapping portion in which the packaging body is folded and overlapped so that one part of the packaging body overlaps with another part of the packaging body provided with a part that inhibits thermal welding on the surface side. Another object of the present invention is to provide a packaged food that can be fixed by heat-sealing each part of the package.

  Furthermore, in view of such circumstances, the present invention provides a sheet fixing device capable of thermally welding and fixing each sheet even in an overlapping portion where at least one sheet overlaps a sheet provided with a portion that inhibits thermal welding on the surface side. It is another object of the present invention to provide a sheet fixing method.

  According to the present invention, at the overlapping portion where the package is folded and overlapped, at least one of the parts of the package is penetrated and heated at the part through which each part of the package is penetrated. The parts having heat weldability in each part of the package are heat welded. Thereby, since each site | part of the package in an overlap part is fixed, cooked rice processed food is packaged with a package. Furthermore, when the pair of sheets that are sealed to each other are separated and removed in the width direction, the sheet-like food interposed between the pair of sheets remains so as to cover the surface of the processed rice food. In addition, the cooked rice processed food and the sheet food can be easily combined.

  Further, in the packaged food according to the present invention, the outer part of the sheet-like food in the package body is one sheet in the package body, and is folded so as to overlap the part where the surface-inhibiting part is provided on the surface side. In order to fix the outer part of the sheet-like food and the one sheet in the rare overlapping portion, at least the outer part of the sheet-like food is penetrated from the outer part of the sheet-like food to the part that inhibits thermal welding on the one sheet.

The protective member protects the sheet-like food when it is penetrated from the outer part of the sheet-like food to one sheet in the folded overlapping portion. For example, even if the sheet-like food is penetrated from the outer part to one sheet, the protective member is not penetrated, so the outer part of the sheet-like food and one sheet are not damaged without damaging the sheet-like food. And can be fixed.

  In the packaged food according to the present invention, when the cooked rice processed food formed in a triangular shape is packaged in the package formed in a rectangular shape with the other sheet inside, the bottom surface of the cooked rice processed food is the package. One side of the triangular shape of the cooked rice processed food is covered with one side in the longitudinal direction of the package, and the other side of the triangular shape of the cooked rice processed food is in the longitudinal direction of the package so that it is disposed at the center in the longitudinal direction. Covered on the other side, and both corners in the overlapping portion formed by folding so that both corners on one side in the longitudinal direction of the package overlap with the other side in the longitudinal direction of the package are sheet-like The outer part of the food and the one sheet may be fixed.
