Description

  The present invention relates to a packaging sheet in which a sheet-shaped food is sandwiched between an inner film and an outer film, and a packaging bar-shaped food in which a rod-shaped food is packaged by the packaging sheet.

Conventionally, a wrapping stick-shaped rice wrapping a wrapping sheet, which is formed by sandwiching a sheet-like seaweed between a rectangular outer film and an inner film and welding the outer peripheral portions of both the inner and outer films around the peripheral surface of the stick-shaped rice, Are known.
The outer film is provided with a severable portion that can be divided into two at a substantially central portion, and the inner film is formed by overlapping the inner ends of two substantially identical film pieces on the severable portion of the outer film. .
The packaging stick-shaped rice is placed on the inner film of the packaging sheet so as to be perpendicular to the overlapping portion of the film pieces, the packaging sheet is wound around the circumferential surface of the stick-shaped rice, and the winding end is stopped with a label.

In order to unwrap the packaging rod-shaped rice, the label is peeled off, the film on one end side of the packaging rod-shaped rice is pulled outward to divide the outer film, and half of the outer film and one film piece of the inner film are pulled out together.
Pull out half of the outer film left on the stick-shaped rice and the remaining film piece to the opposite side. As a result, only the sheet-like seaweed remains on the stick-shaped rice and directly covers the stick-shaped rice.

When the part where the outer film can be cut is a cut tape, if the film is first cut by pulling the cut tape, it takes time to pull the cut tape, but there is no problem in unpacking.
However, in the case where the severable portion of the outer film is an intermittent cut (so-called `` perforation '') made on the film, the outer film can be cut off well when the cut is not on the edge of the outer film. In some cases, stick-shaped rice may lose its shape.
The present invention clarifies a packaging sheet and a packaging bar-shaped rice packaged with the packaging sheet, in which the part of the outer film that can be divided by intermittent cutting can be smoothly divided.

The packaging sheet according to claim 1 has a sheet-like food (4) sandwiched between a rectangular outer film (2) and an inner film (3), and the outer peripheral portions of both the inner and outer films (2) and (3) are welded. The outer film (2) is provided with a severable part (21) that can be divided into two parts at a substantially central part, and the inner film (3) is an inner part of two substantially identical film pieces (31) (31). In the packaging sheet formed by overlapping the ends on the separable portion (21) of the outer film (2) and wrapping the outer peripheral surface of the rod-shaped food (7) in the direction of the separable portion (21),
The severable portion (21) of the outer film (2) is formed by intermittently cutting (22) the film, and a notch is formed at the substantially central portion of the winding start end (23) of the outer film (2). (24) is provided, the notch is expanded from the inner end to the outer side, and the inner end is hooked on the separable portion (21).

  According to a second aspect of the present invention, in the packaging sheet of the first aspect, end face covering pieces (51) and (51) are provided on the inner film (3) so as to cover the end face of the rod-shaped food (7) to be packaged.

The sheet-like food (4) of the example is a sheet-like nori (hereinafter, simply referred to as “nori”) having a length of about 130 m and a width of about 100 mm.
The outer film (2) and the inner film (3) have a rectangular shape slightly larger than the laver (41).
The length and thickness of the stick-shaped food (7) are such that the laver (41) can wind the outer periphery of the stick-shaped food (7) slightly more than one round.
The rod-shaped food (7) is in the form of a roll having a length of about 100 mm and a diameter of about 40 mm, and is a rod-shaped rice (71) in the embodiment.

The outer film (2) has a separable part (21) capable of dividing the outer film (2) into two along the longitudinal direction at the center in the width direction.
The splittable portion (21) is an intermittent cut (22) (so-called “perforation”).
Further, the outer film (2) is provided with a notch (24) at the center of the winding start end (23) around the stick-shaped rice (71).

The notch (24) expands from the inner end to the outer side (the winding start end (23) side), and the narrow portion of the inner end is hooked on the separable portion (21). The cutout (32) of the embodiment has a triangular shape that is sharp so that the inner end is concentrated at one point.
The inner end of the cutout (32) may be located at the connecting portion of the film between the cut and the cut as long as it is on the cut line of the cuttable portion (21).

  On the inner surface of the outer film (2), a strip film (8) covering the intermittent cut (22) and blocking the ventilation is covered over the entire length of the outer film (2), and the outer film (2) is divided. It is welded to the outer film (2) so that there is no problem.

  The inner film (3) is formed by simply overlapping the inner end portions of two substantially identically shaped film pieces (31) (31) with a width of about 10 m.

  The outer peripheral edges of the inner film (3) and the outer film (2) are welded and joined in a linear manner so as not to overlap the overlapping portion (30) of the film pieces (31) and (31). .

The covering film (5) has a long rectangular shape in a direction perpendicular to the outer film (2), straddles the two film pieces (31) and (31) of the inner film (3), and both ends of the inner film (3). It protrudes and approaches the notch (32) of the outer film (2) and covers the inner film (3).
The length of the covering film (5) is a length obtained by adding about four times the diameter of the rod-shaped rice (71) to the length of the rod-shaped rice (71), and is about 260 mm in the embodiment. The width of the covering film (5) is about twice as long as the thickness of the stick-shaped rice (71), and is about 80 mm in the embodiment.
The covering film (5) is about twice as long as the diameter of the rod-shaped rice (71) and protrudes from both ends of the inner film (3).
The covering film (5) is linearly welded to the inner film (3) in the width direction of the covering film (5) between the end covering pieces (51) (51) and the laver (41) (53 ) (53).
The covering film (5) is cut (52) at the center of the length.

Since the packaging sheet (1) of the embodiment opens the notch (24) in the outer film (2) after welding the outer periphery of the outer film (2) and the inner film (3), In the film (3), notches (81) and (32) having the same shape are opened at the same position as the notch (24) of the outer film.
The end of the wrapping sheet (1) on the side of the notches (24), (81) and (32) is the winding start end (12) for the stick-shaped rice (71), and the end on the opposite side is the winding end (13) It becomes.

On the packaging sheet (1), opening marks (11) and (11) are provided at both ends of the inner position by the length of the diameter of the stick-shaped rice (71) from the winding end (13).
As will be described later, the opening mark (11) is a measure of how much the winding end (13) of the packaging sheet (1) should be opened when unwrapping the packaging rod-shaped rice ball.
The opening marks (11) and (11) in the examples are given to the outer film (2) and can be seen through the inner film (3).
In addition, after opening the winding end (13) of the packaging sheet (1) to the packaging sheet (1), when one end of the rod-shaped rice (71) is pulled outward as described later, the rod-shaped rice (71 ) Is provided with a finger position mark (14) indicating the position and direction of the thumb of the finger that holds the other end.
The finger position mark (14) is provided by illustrating the tip of the thumb.
In the embodiment, the finger position mark (14) is for the thumb of the left hand, and as shown in FIG. 4a, the thumb is notched toward the upper left end of the packaging sheet (1) with the notch (24) facing upward. It is shown in the direction of (24).

Further, a label (62) which is a fastening means (6) for fastening the end is attached to the winding end (13) of the packaging sheet (1) of the embodiment.
The label (61) is about the length of the stick-shaped rice (71), and the back surface is an adhesive surface.
The label (61) protrudes from the winding end (13) of the packaging sheet (1) by about 1/2 of its width over the entire length.

  However, in order to wrap the stick-shaped rice (71) with the wrapping sheet (1), as shown in FIG. 1, on the covering film (5) located on the winding start end (12) side of the wrapping sheet (1). The rod-shaped rice (71) is placed, and the end surface covering pieces (51) (51) of the covering film (5) are folded inward so as to cover both end surfaces of the rod-shaped rice (6).

Since the horizontal length of the label (61) is about the same as the length of the stick-shaped rice (71), the winding end (13) can be firmly fixed so that the both end sides are not broken.

  The laver (41) of the packaged stick-shaped rice is sandwiched between the outer film (2) and the inner film (3), is shielded from the outside air and moisture from the stick-shaped rice (71), and does not lose the crispy feeling. The stick-shaped rice (71) is sanitary because the edge-covered pieces (51) (51) are covered not only on the peripheral surface but also on the end face, and the stick-shaped rice (71) is prevented from drying and has a flavor. Will not be damaged. Foreign matter can also be prevented from entering.

To eat the stick-shaped rice (71), as shown in FIG. 4a, the label (61) is peeled off and the winding end (13) of the packaging sheet (1) is opened. What is necessary is just to open so that the opening mark (11) of an above-described packaging sheet (1) can be seen from the inner side of a packaging sheet (1).
It is troublesome to completely remove the label (61) from the packaging sheet (1), and it is better to leave the label (61) on the winding end (13) for the reason described later.

Next, the stick-shaped rice (71) is gripped from the top of the packaging sheet (1) with the left hand, and the film on the opposite side of the stick-shaped rice (71) is pulled outward with the right hand.
Since it is sufficient to support the stick-shaped rice (71) by placing the thumb of the left hand on the finger position mark (14) of the packaging sheet (1), the position where the stick-shaped rice (71) is held is not lost.
When the film is pulled as described above, the outer film (2) is notched (24) (81 (32)) at the center of the winding start end (12) of the packaging sheet (1). The notch expands from the inner end to the end side (23), and the narrow portion of the inner end is hooked on the separable portion (21), so the tensile stress of the film is applied to the inner end of the notch (24). concentrate.

Therefore, even if the inner end of the notch (24) is located at the connecting portion of the film between the notches of the intermittent notches (22) of the severable portion (21), the concentration of the tensile stress causes Easily connected to the incision, and then the intermittent incision (22) is smoothly connected, so that the outer film (2) can be divided, and the outer film (2) and the inner film (3) ) One film piece (31) can be pulled out together.
Since the film pieces (31) and (31) of the inner film (3) are simply overlapped, and the cover film (5) is divided at the center, there is no problem with the division of the outer film (2). There is no.

Grab the stick-shaped rice (71) on the side where the outer film (2) and half of the inner film (3) are pulled out and the seaweed (41) is exposed from the top of the sheet-like food (4), Pull out the other half of 1) by pulling it to the opposite side. As a result, the seaweed (4) is completely exposed, and the operation of unwrapping the packaging directly on the stick-shaped rice (71) is completed.
Since the packaging sheet (1) divided into right and left is connected by the label (61), it is not scattered and easy to clean.
