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. Laminate the backside film with the overlapping part between the film pieces at the location located at the position, and join the part 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-mentioned problem, as shown in FIG. 14, the package body is made by a sheet body 50 having a dividing means over the entire length, and the rice ball R is wrapped in the package body. In the first step of folding the sheet body into a U-shape so that it comes into contact with the bottom surface of the rice ball and then the other surface with the one surface in contact, the front portion 51 of the packaging body, Left and right side flanges of the package by the second step of forming the part 52 and the back part 53, and further folding the front part, the bottom collar part, and the back part of the sheet body protruding to the left and right sides of the rice ball and fixing them to the rice ball side. 54, 54 is formed to form a rectangular parallelepiped package, and finally the front and back portions are overlapped and closed at the opening while the side flanges of the package are folded inward by the folds 54A. about More, packaging with molded boiled rice food is closely least the rice balls over three sides of the inner wall surface of the package has been filed (- unpublished at the time of patent document 1 herein). Here, as the sheet body 50, a rectangular front side film comprising a cutting means 55 made of a cut tape 55 is overlapped with a back side film made up of a pair of film pieces divided into two in the short direction, and a sheet of laver or the like inside. What joined the periphery of the front side film and the back side film so that the bag part for accommodating a foodstuff may be used is used.

According to the above-described invention, the package is brought into close contact with the rice ball R and has an effect of being securely fixed in the package.
Japanese Patent Application No. 2003-64706

  By the way, when the above packaging is performed by an automatic packaging apparatus, the sheet edges constituting the left and right side flange portions 54 and 54 are joined to each other as shown in FIG. Occasionally, a defective product in which the protruding portion E1 is formed at the upper portion of the portion occurred. As a result, the front part 51 and the back part 53 of the package are shifted to the left and right, the heights do not match, and the opening is obstructed, and at the same time, the centers of the front part 51 and the back part 53 of the sheet body 50 are also matched. As a result, there arises a problem that the front end side and the rear end side of the cut tape 55 that should be matched deviate from each other.

  Similarly, due to inadequacy in the process, a defective product having the overlapping portion E2 in which the sheet ends constituting the left and right side flange portions 54 and 54 are inadvertently folded is occasionally generated as shown in FIG. In this case, since the number of overlapping sheets in the upper part of the packaging body is increased by the superposition part, a problem that adversely affects the sealing operation when the upper part of the packaging body is closed occurs.

  This invention was created in order to solve the above-mentioned problem, and on the rectangular front side film provided with a dividing means over the entire length, a back side film composed of a pair of film pieces divided into two in the short direction was overlaid, It consists of a package formed by a sheet body in which a part of the front side film and the back side film are joined so as to constitute a bag part for containing sheet-like food inside, and a molded cooked rice food packaged in this, In the first step of bending the sheet body into a U shape so as to contact the bottom surface of the molded cooked rice food and then the other surface in a state where one surface in the front and back of the molded cooked rice food is in contact, Form the front, bottom and back parts of the package while wrapping, and then fold the front, bottom and back parts of the sheet that protrudes from the left and right sides of the shaped cooked rice food into the shaped cooked food side and fix them together. In the second step, the left and right side flanges of the package are formed to form a rectangular parallelepiped package that opens upward, and finally the front and back portions are folded while the side flange of the package is folded inward. The packaged cooked cooked rice food that has been polymerized and closed in the opening is characterized in that notches are provided at the four corners of the sheet body.

  In this invention, since the sheet body is folded in a U-shape while wrapping the shaped cooked rice food, the four corners of the sheet body are positioned at the upper end of the packaging body with the front and rear ends of the sheet body facing each other during packaging. It becomes. Therefore, by cutting out these four corners, even if the sheet ends constituting the left and right side flanges are shifted up and down due to inadequacy in the process, the sheet end is formed on the upper end of the package by the notch. Since no is located, it is prevented that a protrusion part is produced in the upper side of the side collar part (see FIG. 4).

  Similarly, since the sheet end is not located at the upper end of the package due to the notch, it is possible to prevent the overlapped portion in which the sheet end is inadvertently folded back.

  On the other hand, at the upper end of the packaging body due to the cutout portion, the number of overlapping sheet bodies constituting the folding portion 5 having the M-shaped cross section of the side collar portion is not 6-fold (see FIG. 7) but 4-fold (see FIG. 7). (See FIG. 6), the effect of improving the sealing performance is also produced.

  FIG. 2 to FIG. 3 are views showing the relationship between the sheet body and the shaped cooked rice food in the packaged shaped cooked rice food of the present invention. Here, a triangular rice ball is illustrated as the shaped cooked rice food. In the figure, reference numeral 1 denotes a sheet body, and the regions constituting the front portion A, bottom ridge portion B, and rear portion C of the package body with the folds 2B and 2B as the boundary in a state where the rice ball R is in contact with the front is the front of the rice ball. Then, the regions 3 and 3 constituting the side flange portions D and D of the package are folded to the rice ball side with the folds 2A and 2A as a boundary. At that time, the regions 3 and 3 constituting the side flange portions D and D of the package and the region 4 sandwiched between the folds 2A are folded at the folds 2B, 2B and 2C and 2C, and the regions 3 and 3 Polymerized on the back side.

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

  Next, the front portion A and the rear portion C are overlapped at the opening while the side flange portions D and D are folded inward so that the crease 5A protrudes toward the inside of the package while forming the folding section 5 having a M-shaped cross section. (See FIG. 5) By further closing (not shown), a series of packaging is completed.

  FIG. 1 is a diagram showing a configuration of a 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-side film 10 has a rectangular shape, and has a dividing means by strip-shaped cutting for dividing 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. However, as long as the front film 1 can be stripped by being pulled up, 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 at a location excluding the overlapping part between the film pieces of the back side film, and are 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.

  Notches 20, 20, 20, 20 are provided at the four corners of the sheet body 1 described above, and these constitute the characteristic part of the present invention. In this embodiment, the cutout portion 20 is formed by cutting off the four corners of the sheet body into a square in which L and K are combined, but the shape is not limited to this. FIGS. 8 to 13 are diagrams showing examples of the shape of the cutout portion 20.
