DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging sheet formed by sandwiching a sheet-like food such as a sheet of seaweed between an outer film and an inner film, and a package of conical rice wrapped by the packaging sheet. It is.

[0002]

2. Description of the Related Art Onigiri rice is wrapped in a wrapping sheet having a sheet of laver sandwiched between an outer film and an inner film to prevent moisture from the laver,
2. Description of the Related Art A packaging sheet and a packaged onigiri that allow a user to remove an outer film and an inner film when eating a rice ball and directly apply a dried sheet of seaweed to the rice ball are widely known.

[0003] Also, mass production of packaged conical rice chunks in which substantially conical rice chunks are wrapped with a packaging sheet has been performed by mechanical force. As shown in FIG. 8, a conventional wrapping sheet used for wrapping conical rice blocks has an outer film (1) and an inner film.
(2) sandwich the sheet laver (31) and the outer film (1)
And the outer periphery of the inner film (2) is thermally welded.
The inner film (2) consists of two large and small rectangular film pieces (23) (2).
4) is overlapped on the inner edge of each other.
(20) is orthogonal to the longitudinal direction of the inner film (2). The substantially conical rice block (5) is placed in a state where the tapered tip thereof is located substantially at the center in the longitudinal direction of the inner film (2), and the packaging sheet is wound around the conical surface of the rice block.

In order to eat the rice block, the package is once unwrapped as shown in FIG. 9A, and while the conical rice block (5) is placed on the large film piece (23), the small film piece (24) is put on the outer film. Remove from (1) and expose the sheet laver (31). Next, as shown in FIG. 9B, the rice block (5) is rolled to expose the exposed sheet-like laver (31).
Put on top. The outer film (1) and the large film piece (23) are pulled to expose the whole sheet laver (31) as shown in FIG. 9C, and the conical surface of the rice block (5) is exposed by the sheet laver (31). Wrap.

[0005] When the rice block (5) is covered with the sheet-shaped laver (31), the conical rice block is spread once, and the rice block (5) is moved on the sheet to perform the above operation. It was time-consuming and time-consuming, and sometimes the rice block (5) slipped off the sheet. Further, as shown in FIG. 9A, since the small film piece (24) of the inner film (2) has to be peeled from the outer film (1), the outer peripheral edge of the small film piece (24) and the outer film piece (1) is removed. Heat welding must be weakened. Since the heat welding of the film pieces (23) and (24) to the outer film (1) is performed by a common heat pressing roller on the same welding line, the welding force of the large film (23) to the outer film (1) is inevitable. Weakened. That is, the inner film (2) is welded to the outer film (1) in a state where it is easily peeled off.

Therefore, at the time when the packaging sheets are bundled and set in the automatic winding device, either one of the large and small film pieces (23) and (24) of the inner film (2) or both film pieces are replaced with the outer film ( In some cases, it was peeled off from 1), causing troubles in the packaging device, or incompletely packaging the rice block (5). The present invention is to clarify a packaged conical rice block and its packaging sheet that can solve the above problems.

[0007]

According to the present invention, there is provided a packaging sheet in which an outer film and an inner film are overlapped, the outer peripheral edge is thermally welded, and a sheet-like food (3) is stored between the outer film and the inner film. The both ends of the packaging sheet (4) are tapered, and the outer film (1) has a separable portion (11) at a substantially central portion in the width direction along the longitudinal direction of the film, and the inner film (2) Consists of two film pieces (21) and (21) whose inner edges overlap on the separable part (11), and two pieces cut in accordance with the cut shape of the end of the packaging sheet (4) Sheet of food
(3) (3) is accommodated at both ends of the wrapping sheet, and two sheets of food (3) are provided at the center in the longitudinal direction of the wrapping sheet.
(3) The interval is characterized by an interval corresponding to the enlarged portion of the substantially conical rice block (5) to be packed.

The packaged conical rice block of the present invention comprises a substantially conical rice block (5) substantially at the center of the inner film (2) of the packaging sheet (4).
Of the packaging sheet (4), and fold the both ends of the packaging sheet (4) so that they overlap with the tapered portion of the conical rice block (5).
(41) Wrap both ends of (42) so as to cover the conical surface of the substantially conical rice block (5), and pass through the outer film (1) between the two sheets of food (3) (3). Shows the enlarged end face of the substantially conical rice block (5).

[0009]

[Operation and Effect] At the end of the wrapping sheet (4) located at the tapered portion of the wrapped conical rice block, the outer film (1) is torn to the left and right from the separable portion (11) to divide it into two parts. Inner film (2)
Is the inner edge of the two film pieces (21) and (21)
The outer film (1) is separated from the beginning only because it is overlapped on the separable part (11) of (1). The heat-sealed film pieces (21) and (21) are also pulled out together and
(3) Only (3) remains and directly covers the conical rice block (5).

Since both ends of the packaging sheet (4) are tapered, when the conical rice block (5) is wrapped so that the tapered portion of the sheet corresponds to the tapered portion of the rice block, the separable portion ( The outer film (1) can be smoothly divided into two from the separable portion (11) without covering both sides of the sheet end portion on (11).

The sheet foods (3) and (3) are moved to both sides of the packaging sheet (4), and the sheet foods (3) and (3) are put on a conical rice block (5).
Since the space W is present corresponding to the large-diameter end face, the large-diameter end face of the conical rice block (5) can be seen through the outer film (1), so that the display effect can be enhanced. Also, conical rice block
(5) The whole can be wrapped in the wrapping sheet (4), which is hygienic.

Further, a film piece (21) of the outer and inner film (2)
(21) and the film (1) are pulled out together when unpacking, so that the outer film (1) and the film pieces (21) and (21) can be strongly heat-welded so as not to peel off. Can be prevented from being caused by poor welding.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The outer film (1) and the inner film (2) are both formed by cutting both ends of a rectangular transparent film having a length of about 290 mm and a width of about 120 mm into isosceles triangles. The cut length is about 60 mm in the longitudinal direction of the film and about 5 in the width direction.
0 mm.

The outer film (1) has a separable portion (11) formed at the center in the width direction over the entire length in the longitudinal direction. The separable part (11) of the embodiment is a so-called cut tape (12) in which a strip-shaped tape called "cut tape (12)" is adhered to the film. When one end of the cut tape (12) is pulled, the film is torn at the tape part for 2 minutes. it can.

The inner film (2) is a film piece (2) of the same shape.
1) (21) is formed by overlapping the longitudinal inner edges of each other so as to overlap the cut tape (12) of the outer film (1), and the overlapping portion (20) of the film pieces (21) and (21) is Alternatively, they may be simply overlapped, or may be weakly spot-welded so as to be easily peeled off.

The inner film (2) and the outer film (1) are welded by heat welding at the outer edges except for the vicinity of the overlapping portion (20) of the inner film (2) and the separable portion (11) of the outer film (1). Are joined.

Two sheets of food (3) (3) are accommodated between the outer film (1) and the inner film (2). The sheet food (3) of the embodiment is a sheet of seaweed. Sheet food
(3) is cut in accordance with the cut shape of the ends of both the inner and outer films (2) and (1), and is positioned close to the ends of the inner and outer films (2) and (1). I have.

Between the sheet-like foods (3) and (3), the large-diameter end surface of the substantially conical rice block (5) to be packaged at the center in the longitudinal direction of both the inner and outer films (2) and (1). The interval W is open corresponding to the diameter of.

A substantially conical rice block (5) is formed on the packaging sheet (4).
The procedure for wrapping is described. As shown in FIG.
At the approximate center of the inner film (2) of (4), the enlarged distal end surface of the conical rice block (5) is placed, and as shown in FIG. 4, both ends of the packaging sheet (4) are placed on the conical rice block (5). Fold it up so that it overlaps with the tapered part, and furthermore, as shown in FIGS. 5 and 6, both ends of both folds (41) and (42)
(41a), (41a), (42a), and (42a) are wrapped so as to cover the conical surface of the substantially conical rice block (5).

As shown in FIG. 6, the sheet ear sides (43) projecting from both sides of the large-diameter end face of the substantially conical rice block (5) are directed toward the conical surface of the substantially conical rice block (5). Then, as shown in FIG. 7, it is stopped by heat welding, a seal (44) or the like.

Since both ends of the packaging sheet (4) are tapered, when the conical rice block (5) is wrapped so that the tapered portion of the sheet corresponds to the tapered portion of the rice block, the separable portion ( 11) The sides of the sheet end are not covered.

However, the outer film (1) is torn right and left at the separable portion (11) at the end of the packaging sheet (4) located at the tapered portion of the packaging cone-shaped rice block, and is divided into two parts. Inner film
In (2), since the inner edges of the two film pieces (21) and (21) are merely overlapped on the separable portion (11) of the outer film (1) and are separated from the beginning, 2 When the separated outer film (1) is pulled outward, the film pieces (21) and (21) are also pulled out together, leaving only the sheet foods (3) and (3) and the conical rice block (5).
Cover directly.

The sheet-shaped foods (3) and (3) lean toward both sides of the packaging sheet (4), and a conical rice block is provided between the sheet-shaped foods (3) and (3).
Since there is a gap W corresponding to the large-diameter end face of (5), the large-diameter end face of the substantially conical rice block (5) can be seen through the outer film (1), thereby enhancing the display effect. Can be.

The whole conical rice block (5) is wrapped in a wrapping sheet (4) and is sanitary. As another example of the separable part (11), a directional film which is easily torn only in the longitudinal direction is used for the outer film (1), and two cuts are made close to each other at the center of the end of the outer film. Alternatively, the film may be cut in the longitudinal direction by cutting between the cuts to divide the film into two.

Further, the outer film (1) may be provided with intermittent cuts (perforations) over the entire length in the longitudinal direction at the center of the width thereof to form the separable portion (11). Sheet food (3)
In addition to the sheet-like laver, any edible sheet-like material such as a sheet-like kelp may be used. The conical rice block (5) may be mixed with cooked rice, or the cooked rice may be placed on the large-diameter end. In the packaging state of FIG. 7, if the winding end of the sheet is likely to be rolled up, the portion may be stopped by heat welding, sealing, or the like.

The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the claims.
