[Detailed description of the device]

[0001]

[Industrial field of application] The present invention is designed so that a wrapping material such as seaweed and a food main body such as nigiri rice can be packaged in a separated state, and the packaging material can be divided and removed so that they can be combined and eaten as they are. Regarding food packaging.

[0002]

2. Description of the Related Art In the packaging of seaweed rolled nigiri rice, it is possible to store the seaweed and the nigiri rice in a separate state so that the seaweed does not get damp, and to cover them in a substantially sealed state for hygiene, and to provide a food packaging device that is easy to manufacture. Required. As a packaging tool of this kind, a sheet-like structure in which both are wound in a separated state, a bag-like structure in which both are separated and stored in an inner and outer double bag, a combined structure in which a bag and a sheet are combined, a divisible double sheet There is known a split-type sheet-like structure or the like in which both are packaged in a separated state.

[0003] Among these packaging tools, the seaweed and the nigiri rice can be reliably separated from each other, the packaging work is performed by simple winding, and the union and the removal of the both at the time of eating are performed by simple division. As a split type sheet-like structure that is most convenient to manufacture and use
No. 61-103377, No. 61-194658,
No. 63-86085 and the like are disclosed.

[0004]

[Problems to be Solved by the Invention] However, in all of these, the inner side portions of two inner films are polymerized and used,
When viewed in a laminated state of the inner and outer films, it is devised as a three-layer structure, so that there is a problem in that it is not sufficient in terms of manufacturing simplicity.

The present invention focuses on this problem, can further simplify the manufacturing work, makes the wrapping such as seaweed and the like sufficiently isolated, and easily matches the wrapping with food mainly such as nigiri rice, The object of the present invention is to provide a food packaging tool in which the ease of eating is sufficiently maintained.

[0006]

In order to solve the above-mentioned problems, the present invention provides an outer film in which a tear line such as a perforation is formed in the stretching direction near the center of a substantially rectangular uniaxially stretched film. And an inner film having substantially the same shape and a broken line having substantially the same structure, and a winding tool such as seaweed is interposed between both films to polymerize both films and integrally bond the peripheral portions thereof. The present invention is characterized in that it is a food packaging tool having the following structure.

[0007]

[Function] A food packaging can be manufactured by polymerizing two films inside and outside, and at the time of eating, the inner and outer films can be pulled to the side by pulling sideways by pinching near the central end of the inner and outer films. Can be divided at the same time, and can be easily divided into two parts according to the orientation of the film and then extracted at the same time.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1A shows the outer film 1, which has a rectangular shape in the drawing, but may have a shape obtained by cutting off the upper two corners or squares, or another shape, and stretches in one direction, that is, the longitudinal direction. It is formed, and a perforation 2 as a breaking line is formed in the central portion in the stretching direction.

The film may be any material having a softness suitable for packaging such as a polypropylene film or a laminated film. In addition to the perforations 2, the breaking line may be an interrupted or continuous cutting groove streak, weakening streak, etc. The perforation-free surface 3 is formed near both edges in the extending direction, and the perforation 2 is It is formed only near the center.

FIG. 1B shows the inner film 4,
A sewing machine as a breaking line along the stretching direction in the vicinity of the central portion like the outer film 1, which is a film having substantially the same shape as the outer film 1 or a material having substantially the same shape, which is thinner or softer, and which is preferably a film having good slidability. Eyes 5 are formed, and perforations are formed in the vicinity of both edges as a perforation-free surface 6.

As shown in FIGS. 2 and 3, both films 1 and 4 are polymerized with a seaweed 8 having a size suitable for wrapping a nigiri rice 9 between the films, and the peripheral portions are fused and hot-melted. A sheet-shaped food packaging tool in which seaweed 8 is hermetically accommodated inside by laminating 7 by melt-adhesion or other adhering means.

The perforations 2, 5 of both films 1, 4
A cut line for cutting may be formed at the edge of the adhesive 7 on the extension line of the above. Further, the both films 1 and 4 are preferably adhered on the entire four sides, but intermittent adhesion or three-sided adhesion may be adopted.

Thus, in order to wrap the rice ball 9 (the shape and the manufacturing method are not limited, but it will be described as a triangular rice ball shape in the following) with the above food packaging tool, as shown in FIGS. Nigiri rice 9 in the short side direction of the central part of film 4
The nigiri rice 9 may be placed so that the bottom portions of the triangles are aligned with each other, the halves of the food wrapping tool may be sequentially wrapped, and a label or the like may be attached to the outer joining portion for fastening.

In order to eat the nigiri rice 9, as shown in FIG. 6, first, in the above-mentioned packaging state (either the label may be peeled off or the label may be peeled off), the left and right ends of the center two-fold portion of the inner and outer films 1 and 4 may be removed. If you pull near one part and pull one end to one side L or both ends to both sides L and R, the perforations 2 and 5 are in the center part in a direction substantially orthogonal to the pulling direction. As it is formed, the tear direction of the film is given in the same direction,
The central part of the inner and outer films 1 and 4 can be easily divided and the opening 1
0, the opening 10 continues to reach the edge, and the inner and outer films 1 and 4 are divided into two. If it is further pulled as it is, the divided inner and outer films 1 and 4 are simultaneously pulled out while leaving the state in which the seaweed 8 is wrapped around the nigiri rice 9 as it is.

In this way, the seaweed 8 is directly mixed with the nigiri rice 9, and the seaweed rolled rice ball can be obtained as it is. The above-mentioned food packaging excluding seaweed may be divided into both the left and right sides at the same time, or may be extracted into only one side, and the procedure is arbitrary.

The seaweed 7 can be used as an optional wrapping material, and the nigiri rice 8 can be used as an optional food such as bread.

[0017]

According to the above construction, both the outer film 1 and the inner film 4 are perforated only near the center.
It is a single-layered film with break lines such as
Just by interposing a winding tool such as
After that, since the food wrapping can be formed by adhering the peripheral portion thereof, the polymerization work of the inner and outer films with the wrapping material such as seaweed 8 interposed can be easily and easily performed. The manufacturing work (process) is extremely simplified, and an efficient food packaging tool can be manufactured.

[0018] To package food-based products such as nigiri rice 9,
Since the inner and outer films 1 and 4 both have a single film surface, the packaging work is stable and simple, and the side edges are lateral to remove the film portion of the food packaging tool when eating. The inner and outer films 1 and 4 can be easily and accurately divided by simply pulling on the seaweed, and can be easily pulled out.
It is possible to directly eat the both without damaging the wrapping tool such as the above and the food main body such as the nigiri rice 9 and the like.

The break lines of the inner and outer films 1 and 4 do not need to be formed over the entire length, and can be provided as a food packaging tool in which a winding tool such as seaweed 8 is packaged in an isolated and hermetically sealed state, and is broken when not eating. It is possible to maintain the packaging state without the risk of the wire being partially broken, and to maintain hygiene and freshness.
