Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a film for packaging sushi, and is used in the field of selling sushi to take home.

(Purpose of the invention) The purpose of this invention is to prevent sushi rice for take-out sushi from drying out.

(Prior art) Since sushi sold for take-out is usually eaten after a certain period of time has passed after production, the parts of the sushi that come into contact with the outside air, especially the exposed sushi rice, may dry out. However, there was a problem with the taste being bad.

Therefore, packaging films with protrusions that cover the exposed edges of sushi rice have been proposed (for example, Jikkosho
No. 55-38854), there is no known method that can reasonably cover the end surface of conically shaped sushi.

(Structure of the invention) The sushi packaging film of this invention has a rectangular film body that covers the sides of the conically shaped sushi, and a tongue piece that covers the end surface of the sushi that overlaps one side of the rectangular film body that covers the side surface of the sushi. Two edges are fixed to two adjacent edges of the film body.

Preferably, the film body has a bag-shaped glue storage section on one side. Further, the tongue piece is square, each corner is a right angle, the opposing angle is an acute angle, and the two edges sandwiching the right angle corner are:
Adhering to the two edges of the film body (for example, by heat welding)
With this structure, the tip of the tongue can be neatly wrapped around the film body.

(Function of the device) In this device, the film body has the function of covering the sides of the sushi, and the tongue pieces have the function of covering the end surfaces of the sushi, and as a whole, they cut off contact between the sushi and the outside air and prevent drying. It has the effect of slowing progression.

(Example) An example of this invention will be described below based on the drawings.

A tongue piece 2 is superimposed on one corner of a rectangular film body 1. The tongue piece 2 has a rectangular shape with one corner 3 at a right angle, and two edges 2a and 2b sandwiching the right angle corner 3 are welded to the long edge 1a and the short edge 1b of the film body (2a and 2b). is equal length).
An opposite angle 4 of the right angle corner 3 on the tongue piece 2 is an acute angle.

One side of the film body 1 is double-layered and has a bag-shaped glue storage section 5 formed therein. The length of the short edge of the film body 1 is approximately equal to the generatrix length of the conical sushi 6 to be packaged. In the figure, 7 is a notch for air vent. Incidentally, a synthetic resin film is suitable as the material for the film body 1 and the tongue piece 2.

The method of using the packaging film shown in the above example is as follows.

At the same time as storing the seaweed 8 in the seaweed storage part 5, the tongue piece 2 is turned upward, the end surface 6a of the sushi 6 is brought into contact with the inner surface of the tongue piece 2, and then the tip side of the tongue piece 2 is placed on the sushi 6. After aligning it along the side surface 6b, the film body 1 wraps the film 6 and the tip end of the tongue piece 2, and the ends are fixed with a seal 9.

In the above, when the tongue piece 2 is turned upward, a force acts on the tongue piece 2 to return downward, so
The tongue piece 2 can be automatically brought into contact with the end surface 6a of the sushi 6.

According to the above embodiment, the tongue piece 2 is square,
Since the tip angle is an acute angle, the part of the tongue piece 2 that is rolled up into the film body forms an acute triangle, so that it can easily come into contact with the side of the sushi 6 and wrap it in an orderly manner, but the shape of the tongue piece is not limited to this example.

It should be noted that the corner 3 does not necessarily have to be a right angle, but may be of the same size as the corner angle of the film body 1. Therefore, if the corners of the film body are rounded, the corners 3 will also be rounded.

Further, in the above embodiment, a cutout 7 for air venting is provided, but the cutout 7 is not an essential requirement.

(Effects of the invention) In other words, according to this invention, the tongue piece that covers the end surface of the sushi is connected to the film body that covers the side surface of the conical sushi. can be completely covered. Furthermore, since the tongue piece is provided so as to overlap the film body, the tongue piece can automatically come into contact with the end surface of the sushi, and since the two side edges of the tongue piece are fixed to the two side edges of the film body, the sushi When the end surface of the film is brought into contact with the tongue piece, the sushi will inevitably form a predetermined angle with the side edge of the film body, making positioning of the sushi extremely easy. Therefore, sushi can be efficiently packaged without requiring any skill.

However, since the contact between the sushi surface and the outside air is cut off, the progress of surface drying is delayed, which not only makes it possible to provide delicious sushi to take home, but also allows manufacturers to make it in advance. Productivity improves. In addition, since the sushi does not come into contact with the outside air, it is advantageous in terms of hygiene management.
