Description

  The present invention relates to a packaged rice ball, and more particularly, to a packaged rice ball that is wrapped while laver is wrapped in an isolated state, and the laver is wrapped around the surface of the rice ball at the same time that the package is opened and removed.

  A rectangular front side film having a size capable of encapsulating a rice ball and having a cutting means for cutting in two in the short side direction, and a pair of film pieces divided into two in the short side direction. The back side film with the overlapping part of the film pieces is overlapped at the position located at the dividing means of the front side film, and the peripheral edges of the front side film and the back side film are joined except the overlapping part of the film pieces of the back side film. By doing so, a food packaging body in which a pocket portion for accommodating laver or the like is contained is known (Patent Documents 1 and 2).

This package is for packaging rice balls with the back film side in contact with the rice ball side.Specifically, the bottom of the rice ball is positioned near the center of the front and rear of the package, and the After covering the back, cover the front with the front half. In this case, since the rice balls are triangular, the package is rectangular, so left and right margins on the short sides of the front of the package remain on the left and right sides of the package. Folded over the back half of the package covering the back of the package and partially bonded by spot welding with a pair of heat seals made of a circular shape, and then the label is adhered on it to fix the packaging state (Patent Documents 3 to 5). When opening the package, pull the cut tape applied to the front film from the front side of the rice ball to divide the front film into the left and right one after the other, and then fold it over the path of the cut tape. The part (margin part) is also divided. In this case, since the back film has already been divided into left and right by a pair of film pieces, the package will eventually be divided into left and right, and packaged by leaving the nori contained in the pocket part by pulling left and right The body is removed and only the seaweed remains wrapped on the surface of the rice balls.

  By the way, in order to make the package easier to open, it is desired to adopt a wide dividing means. For that purpose, the width of the cut tape is widened, or a pair of cut tapes with a gap are used. .

  FIG. 7 is a view showing an example in which such a package P1 is used for the triangular rice ball R1, but as is clear from the figure, when a wide dividing means is adopted, the cut tapes C and C are spot welded portions H1, It will be close to H1. In this case, the spot welded part is performed at the final stage of packaging the rice balls, but due to packaging variations, the cut tape is shifted to the spot welded part and welded up to the cut tape, making it impossible to cut by the cut tape. Problems were likely to occur.

  In order to avoid the above problems, it is possible to envisage a method in which the spot welded portions H1 and H1 are separated from the cut tapes C and C, that is, the space between the spot welded portions H1 and H1 is widened. Is welded at a position retracted inward from the end, and there is a possibility that sufficient packaging strength cannot be secured.

  The present invention has been created for the purpose of providing a packaged rice ball that solves the above-described problems of the prior art. That is, the packaged rice ball of the present invention is divided into two in the short direction into a substantially rectangular front side film having a size capable of encapsulating the rice ball while having a cutting means for cutting in two in the short direction. The front side film is formed by covering the front side film with a pair of film pieces and overlapping the back side film provided with the overlapping part of the film side at the position located in the dividing means of the front side film, and excluding the overlapping part between the film pieces of the back side film. It consists of a package that forms a pocket for accommodating seaweed inside by joining the edges of the backside film and the triangle rice balls wrapped in this, and the bottom of the rice ball is near the center before and after the package And cover the back of the rice ball with the rear half of the package, then cover the front with the front half and leave the left and right margins of the package. In a rice ball with packaging that is folded and overlaid on the package that covers the back of the rice ball and fixed on the package by spot welding, the shape of the spot welded part is a vertically long shape with the full length direction of the cut tape as the long side. It is characterized by that.

  According to this invention, the shape of the spot welded portion is a vertically long shape with the full length direction of the cut tape as the long side, thereby reducing the overall width while ensuring an area equivalent to the circular spot welded portion of the prior art. It becomes possible. As a result, there is less risk of accidental overlap with the cut tape without spreading the spot welded portion, and the packaged rice ball with a wide dividing means that makes it easy to open the package without damaging the packaging strength. realizable.

  Specific embodiments of the present invention will be described below with reference to the accompanying drawings. 1-6 is a figure which shows the Example of the rice ball with packaging of this invention, FIG. 1 shows a package body, FIG. 2 shows the decomposition | disassembly state. The package P used in the present invention has a structure in which the front film 1 and the back films 4A and 4B are polymerized so as to form a pocket portion for accommodating laver inside. The front film 1 is made of a rectangle having a size capable of encapsulating the rice ball R, and has a cutting tape as a dividing means by strip-shaped cutting for dividing it into two in the short direction. In this embodiment, the cut tape employs a pair of cut tapes 2 and 2 fixed to the back side of the front film 1 as a dividing means. However, it is of course possible to use a single wide cut tape. It is. Further, here, in order to facilitate tearing of the front film 1 at the start of pulling up of the cut tapes 2 and 2, a pair of cuts 3 and 3 are provided on the left and right sides of the start portion of the dividing means at one end of the front film.

  Back film 4A, 4B is a film of the side which touches the surface of rice ball R at the time of packaging, and is comprised by a pair of film piece 4A and 4B divided into 2 in the transversal direction in the shape which covers the front side film 1, These film pieces are An overlapping portion is formed that partially overlaps at a position located in the front-side film dividing means.

  The front side film 1 and the back side films 4A and 4B are polymerized by providing joint portions (not shown) by means such as heat sealing on the four peripheral edges excluding the overlapping portion 5 between the film pieces of the back side film. Thus, a pocket portion for accommodating the laver S is formed inside. Here, a pair of L-shaped cut-off portions 10 and 10 are provided at both front corners of the package P in the longitudinal direction.

  3-5 is a figure which shows the process of the packaging of the rice ball with packaging of this invention. First, the bottom of the triangular rice ball R is positioned near the center of the front and rear of the package containing the seaweed S in the pocket, and the back of the rice ball is covered with the rear half of the package (see FIG. 3). Next, the front half of the package body is covered with the front half of the package body. In this case, the rice ball is triangular, whereas the package body is rectangular, so the corners in front of the package body are the apexes on the left and right sides of the package body. Margins A and A remain. Therefore, the margins A and A are folded over and stacked on the rear half of the package covering the back of the rice ball R and fixed on the package by spot welding, and a label L is further adhered thereon. By doing so, the packaging state is fixed (see FIGS. 4 and 5).

  Reference numerals 11 and 11 in the figure denote the spot welded portions. In this invention, the spot welded portion has a vertically long shape with the full length direction of the cut tape as the long side. In this embodiment, an oval shape is adopted as such a shape. However, as long as it is a vertically long shape, for example, a rectangle as shown in FIG. 6 or other shapes may be used.
