Adhering to the edge of the outer film 2 so as to be substantially parallel to the direction, sandwiching the sheet-like food material 6 between the outer film 2 and the inner films 4 and 5, and providing a notch 7 for triggering a tear. Strip film 8
Is mounted on the outer film 2 in a direction perpendicular to the tearing direction of the outer film 2 to form sleeve portions 9 protruding from both sides of the outer film 2.

FIGS. 1 to 5 show a first embodiment of a food packaging material according to the present invention. FIG. 1 is a front view (a view with the inner films 4 and 5 turned up), and FIG. FIG. 3 is a perspective view showing a disassembled state, FIG. 4 is a view showing a used state, and FIG. 5 is an explanatory view showing a state of opening. The first embodiment is for use in laver winding.

The outer film 2 is a transparent rectangular synthetic resin film having a tearing direction in the longitudinal direction.

The inner films 4, 5 are a pair of rectangular synthetic resin films, each of which is folded substantially at the center in the width direction of the outer film 2, and the folded portions 3 of the inner films 4, 5 overlap. It is arranged like this. The surface of each of the inner films 4 and 5 that overlaps with the outer film is adhered to the outer peripheral edge of the outer film 2 and the outer film 2 and the inner films 4 and 5
And a bag-like material is constituted.

The sheet-like food material 6 is accommodated between the outer film 2 and the inner films 4 and 5 in an area inside the outer peripheral edge. As the sheet-like food material 6, for example, in addition to grilled laver, bonito flakes, kelp and the like can be formed in a sheet shape.

The adhesive used for bonding the outer film 2 and the inner films 4 and 5 is of a weak bonding type which can be peeled off after bonding. It is desirable to use a low-temperature adhesive and to softly bond at a low temperature so that the folded portions of the inner films 4 and 5 do not adhere to each other.

The belt-like film 8 is a transparent rectangular synthetic resin film, which is provided on the outer film 2 by bonding, and is orthogonal to the tearing direction of the outer film 2 and protrudes from both ends at both ends. It has a sleeve 9. The sleeve 9 is used to cover the end surface of the inner food material 10 placed on the inner films 4 and 5.

An opening operation piece 1 is formed substantially at the center of one short side end of the outer film 2. This opening operation piece 1
Can be formed by two notches.

The band-shaped film 8 has a notch 7 formed at one end at the same interval as the opening operation piece 1, and a fragile portion 11 formed at the other end along the tearing direction. . The fragile portion 11 can be constituted by perforations. The opening operation piece 1 is provided at one end and the other end.
Notches having the same intervals as those described above may be formed.

The inside food 10 is placed on the packaging material constructed as described above, the end face of the inside food material 10 is covered with the sleeve 9 of the belt-shaped film 8, and the end of the packaging material is wound. When stopped by a tape or a seal (not shown) or the like, the state shown in FIG. 4 is obtained, and in this state, it is sold at various stores such as a convenience store.

The inner food 10 can be, for example, a rice cooked in a column shape with rice cooked in the center, a kneaded product formed in a column shape, or the like.

When the user holds the food in the state shown in FIG. 4 and pulls the opening operation piece 1 of the outer film 2, the outer film 2
Is made of a film having a tearing direction, so that the film is torn cleanly and parallel to the same width as the opening operation piece 1 to be in a divided state.

At this time, the belt-like film 8 attached on the outer film 2 is also torn at the same time, and is in a divided state. In addition, the inner films 4 and 5 are separated from the beginning.

Then, one of the divided outer films 2 is pulled outward in the axial direction of the food and removed. When pulling the outer film 2, the inner film 4 of the outer film 2,
It is preferable to have an outer peripheral edge portion which is a portion to be bonded to 5. When the outer film 2 is pulled, the sheet-like food 6 is placed on the inner food 10.
Is wound (see FIG. 5). FIG. 5 shows a state where the outer film 2 on the right side in the figure has been removed. In addition, the inner film 5 on the right side in the drawing has shown a state in which the folded portion 3 has disappeared.

Since the inner films 4 and 5 have the outer peripheral edge of one surface formed by being folded back adhered to the outer film 2, the outer film 2 can be pulled outward only by grasping the adhered portion and pulling the outer film 2 outward. It can be removed together with the film 2. In addition, since the inner films 4 and 5 have only the other surfaces that are folded back in contact with the inner food material 10, even if the surfaces are stuck to the inner food material 10, the outer film 2 and the inner film 4, 5 When the portion bonded to the food is pulled in the outward direction of the food, it can be easily peeled off and easily pulled out.

Further, the strip-shaped member in the divided state is also removed together with the outer film 2.

Next, FIG. 6 is a diagram showing a second embodiment of the present invention, and FIG. 7 is a diagram showing a third embodiment of the present invention. 2nd Embodiment, 3rd Embodiment are outer film 2, inner film 4,
5. The dimensions of the belt-shaped film 8 are different from those of the first embodiment, and show that the present invention can be used for onigiri and other foods of various shapes and sizes other than laver rolls.

The packaging method and opening procedure of the second and third embodiments are the same as those of the first embodiment. In addition,
The band-shaped film 8 may be provided so as to be orthogonal to the tearing direction of the outer film 2, but needs to be sufficiently wide according to the size of the end face of the inner food material 10.

[0031]

According to the food packaging material of the present invention, when the opening piece 1 of the outer film 2 is pulled, the strip film 8 is torn together with the outer film 2 when the opening operation piece 1 of the outer film 2 is pulled. When 2 is removed, the inner films 4, 5 and the strip film 8 are also removed at the same time.
It can be opened very easily.

Further, since the inner films 4 and 5 have only one side of the folded film in contact with the inner food material 10, the inner films 4 and 5 can be easily peeled off even if they are attached to the inner food material 10, and can be easily pulled out.

Therefore, even if the inner foodstuff 10 and the sheet-like foodstuff 6 are packaged in a separated state, they can be easily unpacked and eaten.
