Description

  The present invention relates to a packaging member that encloses a sheet-like seaweed to wrap a rice ball body to be packaged, and a packaging rice ball in which the rice ball body is packaged by the packaging member.

  Rice (including cooked rice, etc.) was formed into a suitable shape, and a dried seaweed (hereinafter also referred to as a seaweed) was added to the surface of a rice ball body with appropriate ingredients attached as necessary. Rice balls are on sale. Such rice balls are required to maintain the texture of dried nori when they are eaten.

  Therefore, in Patent Document 1 to be described later for a lunch box store or the like, a container body made of a synthetic resin having a shape corresponding to the shape of the rice ball body is provided to accommodate the rice ball body, and the opening / closing lid of the container body A packaging container is disclosed in which a laver packed with a thin sheet is held in a holding part provided in the part.

  In such a packaging container, the rice ball main body is separated from the seaweed and stored in the container main body, so that the dryness of the seaweed is prevented from being reduced by the moisture evaporated from the rice ball main body, and the seaweed is a thin sheet The seaweed is also prevented from absorbing surrounding moisture. Then, the sales clerk opens the open / close lid at the time of sale, takes out the rice ball main body from the container main body, takes out the seaweed from the holding part and the thin sheet, and then wraps the rice ball main body with the seaweed to make a rice ball to the customer. In order to provide, the customer who eats the rice ball can enjoy the texture of dried nori.

  However, in such a packaging container, the cost required for manufacturing the container main body is high, and there is a problem that the work of holding the laver packed with the thin sheet in the holding portion provided in the lid member is complicated. . On the other hand, when the container body is relatively hard and the nori of a size that wraps the whole rice ball body is held by the holding part provided on the lid member, the nori protrudes from the lid member. There is also a problem that the packaging container holding the container is bulky and inconvenient to carry. Therefore, the following packaging rice balls are commercially available.

  That is, the packaging rice ball has a strip-shaped interior film in which the edges of two films are overlapped at the approximate center in the width direction, and has a width dimension that is substantially the same as the width dimension of the interior film. Triangle is formed by a packaging member in which laver with an area narrower than the area of both films is interposed between the outer film and the outer film formed by extending a cut-off band on the line passing through, and the periphery of the inner film and the outer film is welded. Wrap the rice ball body in a shape so that both ends of the stripping band face each other near the top of the rice ball body, i.e., so that the packaging member is folded in half, and copy the portions near the side edges of the packaging member to the rice ball body. Is folded.

  In such a packaging rice ball, by pulling one end of the separation band to the other end side, the exterior film is separated along the separation band in the direction of both side edges, and then the other two vertices of the onigiri body of the packaging member By pulling the two ears facing each other outward, the two separated parts of the exterior film and the interior film are separated from the line passing through the approximate center in the width direction toward both side edges of the packaging member. The seaweed interposed between the films is pulled out from between the two films, and the rice ball body is discharged from the packaging member into the seaweed, and at the same time as the packaging member is removed, the rice ball body is wrapped with the seaweed to make a rice ball.

  As described above, the packaging member has laver interposed between the exterior film and the interior film, so that the manufacturing cost is low and the packaging member only wraps the rice ball body, so the operation is easy. Moreover, since the outer dimension of the packaged rice ball packaged with such a packaging member is substantially the same as the outer size of the rice ball body, it is not bulky and convenient to carry.
