Description

  The present invention relates to shaped cooked rice foods such as rice balls and sushi, and more particularly to shaped cooked cooked rice foods with packaging.

  A packaged cooked rice food in which a rice ball is housed in a package body in which a sheet body is formed into a rectangular parallelepiped opening upward is known. In the above-mentioned prior art, rice balls are stored in a pre-packaged package, so if the package is made larger than the rice balls and there is no gap between them, the stickiness of the rice will stick to the inner wall of the package. As a result, the rice balls could not be stored well in the package.

  For this reason, there have been problems in that the rice balls move and lose their shape in the package, and the ingredients of the rice balls adhere to the wall of the package. Further, the front film is covered with a pair of film pieces divided into two in the short direction and the front film is divided into a rectangular front film having a cutting means by strip-like cutting for dividing the sheet into two in the short direction. Overlap the backside film with the overlapping part between the film pieces at the location located at the position, and join the peripheral edge of the front side film and the backside film excluding the overlapping part between the film pieces of the backside film, etc. In the case of using a product provided with a bag portion for containing a sheet-like food, there was a problem that the rice balls rolled down from the package as soon as the sheet was divided by the dividing means when the package was opened.

  In order to solve the above problem, as shown in FIGS. 10 to 12, the package includes a package body formed by a sheet body 50 having a dividing means 53 over the entire length, and a rice ball R packaged in the package body. The sheet body is made into a rectangular parallelepiped with the upper side opened, so that at least three of the inner wall surfaces of the package body are brought into close contact with the rice ball, and a pair of side walls 51, 51 opposed to the package body. The ridges 52, 52 from which the fold line 52A protrudes inward are formed, and the ridges increase in ridge depth toward the opening of the package so that the fold line is tapered and is in close contact with both side walls of the rice ball. A packaged cooked cooked rice food was filed as Patent Document 1 (not known at the time of this application). In addition, as shown in FIG. 12, here, a pair of film pieces 61 and 62 divided into two in the short direction are formed into a rectangular front side 60 film having a dividing means 53 for dividing the sheet 50 into two in the short direction. The front side film and the back side film excluding the overlapping part between the film pieces of the back side film are overlapped with each other by covering the front side film and overlapping the film side of the film on the part located at the dividing means of the front side film. The thing which provided the bag part for accommodating the sheet-like foodstuffs N, such as seaweed, is used by joining each other.

According to the invention described above, the package is brought into intimate contact with the rice ball R, and the folding line 52A of the hooks 52 and 52 is in intimate contact with the rice ball as shown in FIG. Arise.
Japanese Patent Application No. 2003-64706

  However, when the opening end 54 of the package is folded back for sealing to seal the opening (see FIG. 11), as shown in FIG. 52 and 52 are positioned and the four sheet bodies are overlapped, and in addition to this, the opening end 54 is folded back so that the eight sheet bodies are stacked and the two sheets are welded simultaneously. The problem is that it is difficult to do.

  This invention is an improved invention of Japanese Patent Application No. 2003-64706 created to solve the above-mentioned problems, and a package body made by a sheet body provided with a dividing means over the entire length, and molded cooked rice packaged therein It is made of food, and the sheet body is made into a rectangular parallelepiped with the molded rice food placed on the upper side, thereby bringing at least three of the inner wall surfaces of the package into close contact with the molded rice food. Formed on the pair of side walls facing each other is a ridge that protrudes inwardly, and the ridge is tapered toward the opening of the package so that the fold line is tapered and close to both side walls of the formed cooked rice food. In molded cooked rice foods with increased depth, a flap piece with a width matching the opening width is protruded from the end of the sheet body at the position located at the opening at the time of bag making, and the flap piece is polymerized at the time of bag making To be The opening is folded back to the other end of the bets body characterized by being welded to both ends of the sheet edge as well as the lid.

  According to the present invention, when the sheet body is folded and the opening of the package body is covered, the number of sheet bodies is reduced by using the flap piece, so that an effect of facilitating welding can be obtained.

  FIG. 1 and FIGS. 2 to 6 are views showing a production process of the first embodiment of the packaged cooked cooked rice food according to the present invention. Here, the cooked cooked rice food is exemplified by a triangular rice ball, and a sheet body at the time of bag making The dividing means is continuous in the vertical direction so as to divide the package into left and right. Reference numeral 1 in the figure denotes a sheet body, and the regions constituting the front wall and the back wall of the packaging body are in close contact with the front and back surfaces of the rice ball by the broken lines 2B and 2B provided in the longitudinal direction with the rice ball R placed thereon. At the same time, the regions 3 and 3 constituting the side wall of the package body are bent by the folding lines 2A and 2A so as to be in close contact with the lower ends of both side walls of the rice ball. At that time, the regions 3 and 3 constituting the side walls of the package and the region 4 sandwiched between the polygonal lines 2A are folded by the polygonal lines 2B, 2B and 2C and 2C, and are superposed on the back surfaces of the regions 3 and 3 (see FIG. 2 to 3).

  Through the above process, a packaging body made of a rectangular parallelepiped opening upward is obtained, and the region 4 that is folded with the regions 3 and 3 constituting the side wall and polymerized on the back surface thereof is simultaneously welded at the welding location S2, and the region 3 3 are also welded together (see FIG. 4).

  Next, the ridge part which consists of the eaves walls 5 and 5 by the broken lines 5B and 5B arranged so that it may incline toward the opening on the front wall and back wall of a package body, and the broken line 5A arranged in the side wall center of a package body. A polygonal line 5A is formed so as to protrude inward of the package and in close contact with the upper side walls of the rice ball R (see FIG. 5).

  The packaging body whose upper portion is narrowed by the flange portion is such that the front wall and the rear wall are superposed in the vicinity of the opening, and the flap piece F having a width matching the opening width protruding from the upper end of the rear wall is the front wall. It is folded back to cover the opening and is welded together with the front wall and the back wall at the welding location S3 (see FIGS. 6 and 1).

  7 to 9 are views showing the configuration of the sheet body 1 used in the above embodiment. This sheet body 1 has a structure in which the front film 10 and the back films 13 and 14 are polymerized so as to form a bag portion for containing a sheet-like food therein. The front film 10 has an overhang 10F projecting at one end to constitute a flap piece F having a width matching the opening width projecting from a location (in this embodiment, the short side end) located at the opening during bag making. It has a rectangular shape, and has a cutting means by strip-shaped cutting for dividing it into two in the short direction. In this embodiment, two narrow cut tapes T1 and T2 fixed to the front film 10 are used as the dividing means. Of course, the dividing means is not limited to a cut tape. Further, in order to facilitate tearing at the start of lifting of the dividing means (cut tape), means such as a pair of cuts may be provided on the left and right of the starting position of the dividing means at one end of the front film.

  The back film is a film that contacts the rice ball R at the time of packaging, and is composed of a pair of film pieces 13 and 14 that are divided into two in the short direction to cover the front film 10, and these film pieces are means for dividing the front film. An overlapping portion is formed that partially overlaps at a position located in the area.

  The front side film 10 and the back side films 13 and 14 are provided with a welded part S1 on the periphery excluding the overlapping part of the film pieces of the back side film and polymerized to form a bag part for containing the sheet-like food N therein. Constitute. In this embodiment, nori is assumed as the sheet-like food N, but the sheet-like food is not limited to nori.

  In this case, in this embodiment, the back side film does not cover the entire surface of the front side film, and the width direction corresponds to the region 4 which is folded with the regions 3 and 3 constituting the side walls during bag making and is polymerized on the back surface. Only the portions other than the left and right regions 11 and 11 are covered (see FIG. 8). By doing so, when the regions 3, 3 and region 4 are welded at the time of consent at the time of bag making, the film constituting the sheet body of that portion becomes only the back side film, and the number of sheets is halved, so that welding is facilitated. An effect is obtained. Of course, the back film may cover the entire surface of the front film without adopting the above configuration.

  Further, at the overlapping portion of the pair of film pieces 13 and 14 of the back side film, a band-like piece 15 is fixed to the end of the film piece 14 so that one end is opened and constitutes a gap 16, and the end of the film piece 13 is placed in the gap. Is inserted (see FIG. 9). By doing so, the effect of preventing the steam generated from the rice balls R during packaging from passing through the sheet body and moistening the sheet-like food N can be obtained. Of course, the strip-shaped piece 15 may not be provided at the end of the film piece 14 without adopting the above-described configuration.

  FIG.15 and FIG.16 is a figure which shows 2nd Example of the molded cooked rice food of this invention. In this embodiment, the sheet body dividing means is continuous in the horizontal direction so as to divide the packaging up and down during bag making. That is, in this embodiment, the regions constituting the front wall, the back wall, and the side wall of the package are formed by the broken lines 31A, 31A, 31A, 31A provided in the short direction with the rice ball R placed on the sheet body 30. It is bent so as to be in close contact with the front and back surfaces, and at the same time, the regions 35, 35 constituting the bottom plate of the package body are bent so as to be in close contact with the bottom of the rice ball by the fold lines 34A, 34A. At this time, the regions 35 and 35 constituting the bottom plate of the package and the region 34 sandwiched between the broken lines 34D are folded by the folded lines 34B, 34B and 34C and 34C, and are superposed on the back surfaces of the regions 35 and 35. Are welded to form the bottom plate of the package (see FIG. 16).

  Next, the ridge part which consists of the eaves walls 31 and 31 by the broken lines 32 and 32 arranged so that it may incline toward an opening on the front wall and back wall of a package, and the broken line 32A arranged in the side wall center of a package may be carried out. A broken line 32A protrudes inward of the package and is formed so as to be in close contact with the upper side walls of the rice ball R (see FIG. 15).

  In the second embodiment, the basic structure of the sheet body 30 is the same as that of the first embodiment, but the position located at the opening at the time of bag making is not the short side end but the long side end. The overhang for constituting the piece F is projected on the longitudinal side of the sheet body 30 (see FIG. 17).
