DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging film for food, for example, for packaging rice balls or for separating them from seaweed.
Also, the present invention relates to a packaged food such as a packaged rice ball.

[0002]

2. Description of the Related Art Conventionally, for example, rice balls and seaweed are packaged in a separated state so that they are hygienic, fresh and the seaweed is fresh. Various types of packaging films and packaged rice balls have been proposed.

[0003] Among them, a laver smaller than the outer shape of the outer film is layered on the inner side of a rectangular outer film, and further, on the inner side, an inner film having a width slightly larger than the width of the outer film divided into two in the longitudinal direction. Using a packaging film in which the sheets are partially overlapped with each other at the center of the outer film, the outer peripheral edge is overlapped with the outer peripheral edge of the outer film, and the inner and outer films are adhered along the outer peripheral edge, and the inner film of the packaging film is used. There is a packaged rice ball on which a rice ball is placed on one half, the other half is folded along the half, and the triangular protruding portions of the inner and outer films are folded, and a label is attached thereon.

Further, an outer film having a perforated shape which is appropriately formed in a conical shape so as to substantially follow the outer shape of a triangular rice ball, and which can be separated from the tip to form a small hole, and an inner film having the same shape as the outer film. There is a packaged rice ball that uses a packaging film in which nori is interposed between the film and rice, and inserts rice balls inside the inner film of the packaging film, folds the opening, and attaches a label.

[0005] In addition, a small nori is appropriately laminated on the inner side of the outer film in which a cutting means such as a cut tape is formed in the longitudinal direction of the central portion of the rectangular body. Two sheets slightly wider than the width divided into two are overlapped with the inner film, the outer film is aligned with the outer edge and the central part is overlapped with each other, and the inner and outer films are heat-sealed along the outer film outer edge with a packaging film. There are packaged rice balls.

[0006] Of the above-mentioned wrapped rice balls, those in which cutting means such as cut tape are formed, when the outer film is cut into the left and right by the cutting means, the inner film becomes a cut form in which two films are polymerized at the center. Because of this, the packaging film is divided into two parts, and one half can be pulled out to the left and right, respectively, and the laver can be combined with the rice. Therefore, compared to the above two forms,
This is suitable in that the operation for obtaining the laver rolled rice ball by opening the packaging film is easy.

[0007]

However, even for a packaging rice ball having a packaging form provided with such a dividing means, the opening operation is a simple operation of dividing the packaging film with a cut tape or the like. There is no play element that allows the user to perform the opening operation while having fun. Therefore, these wrapped rice balls are only capable of providing a seaweed rolled rice ball, and it is difficult to provide pleasure to a meal.

According to the present invention, a food packaging film such as an onigiri, which can enjoy a delicious onigiri by being able to perform an opening operation while having fun by adding a play element to the packaging form having the above-mentioned dividing means, The purpose of the present invention is to provide a packaged food such as a packaged rice ball.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a synthetic resin film capable of packaging food, wherein when the packaging film is a single sheet, a plurality of sheets are polymerized at an intermediate portion thereof. In the case of the state, in the middle of the outer film, a cutting tape is provided or a dividing means capable of dividing the film by providing a cutting direction is provided, and the dividing means is integrated with the dividing means and inside the film. The decorative portion arranged is formed, and in the packaging state, the decorative portion is housed in the film, and is formed so as to be exposed to the outside along with the division by the dividing means, thereby forming a packaging film.

In a synthetic resin film capable of wrapping food, a cutting tape is provided along a longitudinal direction of an intermediate portion of the film, or a separating means capable of dividing the film by providing a tearing direction is provided. It is made into a film, and a small laver is polymerized on the inside of this outer film, and furthermore, two inner films whose width is moderately wider than the half width that divides the width of the outer film in half In a food packaging film having a configuration in which the outer and inner films are polymerized so as to be aligned with the outer peripheral edge of the outer film and their central portions overlap with each other, and the inner and outer films are bonded by heat fusion or the like along the outer peripheral edge of the outer film, A food packaging film characterized by forming a decorative portion integrally and inside the outer film may be formed.

Further, in a synthetic resin film capable of packaging food, the intermediate portion of the film is arranged along a lateral direction of the film.
By providing a cutting tape or by providing a cutting means capable of dividing the film by imparting a tearing direction, etc., an outer film is formed, and a small nori is polymerized inside the outer film, and further, the length of the outer film is further formed inside the outer layer. The two inner films whose widths are appropriately wider than the half-split shape with half the width are polymerized so that they are aligned with the outer edge of the outer film and the central portions overlap each other, and along the outer edge of the outer film. A food packaging film having a configuration in which the inner and outer films are bonded by heat fusion or the like, wherein a decorative portion integrally formed on the dividing means and arranged inside the outer film is formed. You can also

[0012] The inner film is superposed on the outer film so as to form pocket-like portions on both inner portions of the outer film dividing means, and is integrated with the outer film peripheral portion. Interposed, and if necessary, an intermediate film is polymerized between both inner films,

And a food packaging film characterized by the following.

Preferably, any of the above-mentioned packaging films is formed by arranging a plurality of decorative portions along the dividing means, and the film or the outer film is made transparent or translucent. It is more preferable to form an opaque portion of an appropriate width so that the decorative portion is hidden along the dividing means formed in the above, and furthermore, a plurality of decorations representing the shape of a rock-paper-scissor, a choke, and a paper along the dividing means. The parts may be randomly arranged at appropriate intervals. Further, the present invention provides a packaged food by storing a food such as rice or bread in any of the above packaging films and bonding the edges of the packaging film by heat fusion or the like.

[0014]

In the packaging film, since the decorative portion is housed inside the film or the outer film, not only can the decorative portion be hidden at the time of packaging, but also at the time of opening the outer film by a dividing means. By dividing the decorative part, the decorative part is drawn out together with the dividing means, and fun can be obtained by the decorative part that appears.

[0015]

An embodiment of the present invention will be described below with reference to the drawings. Packaging film 1 as one embodiment used in the present invention
As shown in FIG. 1, the outer film 2, the inner film 3,
Nori 5 is interposed between the laver 4 and the laver 4.

The outer film 2 is a transparent or opaque substantially rectangular film made of an arbitrary synthetic resin.
A cut tape 6 (narrow tape for cutting) is provided as an example of a dividing means which is biaxially stretched and can be divided in a longitudinal direction of a central portion of an inner surface thereof, and cut guides 7 are provided at both ends thereof. And further, as shown in FIG.
Along the cut tape 6, both side portions are opaque portions 8 having an appropriate width so that the decorative portion 9 described later is hidden, and the cut tape 6 has a decorative form at regular intervals along its longitudinal direction. For example, a plurality of decorative portions 9 representing the shape of a rock-paper-scissors, a chopstick, and a paper are integrally formed, and are disposed on the inner surface side of the outer film 2 in a free piece state without being adhered.

The decorative portion 9 can be a transparent piece like the inner and outer films 2 or 3 and 4, but can also be colored to be opaque or translucent. This decoration part 9
May be the same material as the cut tape 6 and may be integrally formed therewith, or a separately formed material may be integrally bonded to the cut tape 6. When the outer film 2 itself is made of an opaque or translucent synthetic resin material, the covering effect of the decorative portion 9 can be achieved without providing the opaque portion 8.

The inner films 3 and 4 are made of any synthetic resin, preferably a silicon film obtained by subjecting a polyethylene terephthalate (PET) film to a silicon treatment, or
A film made of a synthetic resin whose surface is processed so that the surface has high slipperiness (to reduce frictional resistance), such as a matte film that has been subjected to matte processing. The width of the short side is appropriately wider than that of the split half-split type.

Using the outer film 2, the inner films 3, 4 and the laver 5, a packaged rice ball 10 can be manufactured as follows. First, the small seaweed 5 is layered on the inside of the outer film 2, that is, on the side where the decorative part 9 is located,
Further, the inner films 3 and 4 are fitted inside the outer films 2 at right and left halves, respectively, to the outer peripheral edge, and the inner films 3 and 4 are overlapped so that the inner side portions of the inner films 3 and 4 overlap each other at the center. As shown in the figure, the inner and outer films 2 and 3 or 4 are adhered along the outer peripheral edge of the outer film 2 by heat fusion or the like, and more preferably, the four corners of the polymerized inner and outer films 2 and 3 or 4 are removed. Forming a cutout portion 11 by diagonally or rectangularly cutout to form a packaging film 1;

Next, as shown in FIG. 3, a triangular rice ball 12 is placed on the inside of one half, that is, on the inner films 3 and 4 so that one side thereof is along the short side of the central portion. As described above, the packaging film 1 is folded in two, and one half portion of the packaging film 1, that is, the inner film 3 side is closely attached so as to be along the side of the rice ball 12, and the inner film 4 side is also along the side surface of the rice ball 12. So that
Then, as shown in FIG. 5, one of the corners is folded so that the notch 11 is substantially positioned on the cut tape 6, and as shown in FIG. The leading end of the folded corner is stopped in the vicinity of the cut tape 6, and each folded portion is folded over the cut tape 6 at the root side portion and the half of the film surface which has already been folded under the cut tape 6. The label 13 may be adhered by heat fusion or the like, and the label 13 may be attached to the outside of both folded corners to form the packaged rice ball 10.

The label 13 is made of an appropriate size of paper or the like covering the folded portion, and a plurality of slits are finely juxtaposed on its lower side (the side on the cut tape 6 starting side of cutting) or upper and lower sides. In addition, it is preferable that the cutting with the cut tape 6 can be performed more smoothly regardless of the displacement due to the sticking. Desired indications such as a product name and a manufacturing date can be given on the surface. Note that the above description does not limit the operation procedure in the manufacturing process, so that the order can be changed in the process design or can be performed simultaneously if the order is possible.

When eating the packaged rice ball 10 having the above structure, first, one end of the cut tape 6 is pulled to start from the triangular surface portion 14 where both corners are not folded, and then to the entire outer film 2 beyond the folded portion. Torn apart. At this time, as the cut tape 6 is pulled out, the decorative portion 9 integrated with the cut tape 6 while being hidden by the opaque portion 8 of the outer film 2 on the side of the triangular surface portion 14 divides the outer film 2. It is pulled out from the part 15 (FIG. 7A).

Therefore, in a simple opening operation of the packaging film 1, when the packaging film 1 is cut by the cut tape 6, the decorative portions 9 appear sequentially. At this time, for example, as shown in FIG. 7 (A), if the decorative portion 9 has the shape of a rock-paper-scissors paperboard, choki, and paper, before the packaging film 1 is divided, It is possible to predict which of the items will be pulled out, and to check the result while pulling out the cut tape 6,
For example, the eater can open the wrapped rice ball while playing a rock, so that the operation of opening the wrapping film 1 can be provided with a game, and the edible rice ball can be enjoyed and enjoyed.

In this case, the decorative portion 9 can be covered with the opaque portion 8 even if the packaging film 1 is transparent, but it is more preferable that the opaque portion 8 be colored to make it opaque or translucent. Alternatively, if the film itself is made of an opaque or translucent synthetic resin material, the decorative portion 9 is completely hidden before opening, and the packaging film 1 is cut by the cut tape 6. The fun is added to the previous expectation, making opening work even more enjoyable.

[0025] Furthermore, if the order of "gu", "choki" and "p" is randomly arranged plurally for each packaging film, or if all of the packaging films are "gull" or "par", the Each time a rice ball is eaten, a different pleasure can be obtained, which is preferable. In addition to this, as another example, as shown in FIG.
The decorative portion 9 may represent the shape of a carp streamer according to the season, or may represent the flags of major countries in the world regardless of the season, as shown in FIG. Further, the decorative portion 9 can be provided with an arbitrary pattern such as a pattern representing a seasonal flower pattern as shown in FIG.

On the other hand, when the cut tape 6 is further pulled out, the cut tape 6 is hardly caught because the cut tape 6 is slightly overlapped with the cut start side because the cutout 11 is formed at the corner where the cut tape 6 is folded downward. Not only that, the tip end does not stop and is a free end, so that the path of the cut tape 6 is not obstructed, the tearing is performed smoothly, and the upper corner is also covered. Despite this, the cutout 6 has very little overlap with the cut tape 6 due to the presence of the cutout 11, and the leading end is a free end.

Further, the central overlapping portions of the inner films 3 and 4 are as follows:
Although not shown, the edge portions of the two films may be folded inwardly (inside of the rice balls) at the overlapping portion, and only the film portion overlapped inside may be folded inwardly. It may be in a form. It is also possible to lightly heat seal the superposed portions of the inner films 3 and 4 so as to easily separate them, but in this case, it is preferable to perform the heat sealing.

In addition, as shown in FIG. 8, the outer film may be an outer film 16, and the outer film 16 is formed along a folded side portion in a folded state.
Cut tape 17 as a dividing means capable of dividing in the transverse direction
Are formed at both ends thereof, and slits 18 are formed for guiding the tearing. Further, along both sides of the cut tape 17, opaque portions 19 having an appropriate width are formed. Of the outer film 16 is integrally formed with the opaque portion 19 of the outer film 16.
Is located inside.

For the outer film 16, see FIG.
(A) As shown in FIG.
Furthermore, two inner films 2 whose inside widths are appropriately wider than the half-split type in which the longitudinal width of the outer film 16 is halved.
1, 22 are superimposed on the outer peripheral edge of the outer film 16 and superposed so that the central portions thereof are overlapped with each other, and the inner and outer films are bonded along the outer peripheral edge of the outer film 16 by heat-sealing or the like to form a packaging film 23. You can also

As shown in FIG. 9B, the outer film 16
The inner films 24 and 25 are respectively polymerized and integrated with the outer peripheral edge of the outer film 16 so that pocket-shaped portions are formed on both inner portions of the dividing means.
The intermediate film 26 is further polymerized between the inner films 24 and 25, and the edge of the intermediate film 26 is fixed to the inner film 24, 25 or the outer film 16 to form a packaging film 27. Can also.

In any of the above embodiments, a film provided with a directionality in the tearing direction can be used as the outer film instead of the outer film provided with the cut tape, or the cut tape and the A film which imparts properties and serves as both can be used as the outer film.

In addition, the shape of the packaging film is not limited to the above, and in the case of an arbitrary synthetic resin film capable of packaging food, when a single film is formed, a plurality of superposed films are provided at an intermediate portion thereof. In the case, in the middle part of the outer film, a cutting tape is provided or a dividing means capable of dividing the film by providing a cutting direction is provided, and the dividing means is integrated with the dividing means and inside the film. The decorative portion arranged is formed, and in the packaging state, the decorative portion is housed in the film and has any configuration as long as it has a configuration formed so as to be exposed to the outside along with the division by the dividing means. good.

Further, in the above embodiment, the onigiri has been described as an example, but the food to be packaged is not limited to onigiri, but may be a sandwich, bread, or other food.

[0034]

As described above, according to the present invention, the wrapping rice ball wrapped with the wrapping film is coated in the outer film, preferably in the opaque portion, by a cutting means such as cut tape in the opening operation when eating. You can pull out the decorated part. Therefore, it is possible to make it unclear what shape the covered decorative part has, so when eating a packaged rice ball, the decoration appears and predicts what will be pulled out, and confirms it in the opening operation In addition to making the opening operation such as doing fun or game-like,
Fun can be provided for meals. Similar effects can also be obtained as sandwich films other than rice balls, bread, and other food packaging films and foods.
