[0019]
DETAILED DESCRIPTION OF THE INVENTION
One embodiment of the packaged food for cooked rice food according to the present invention will be described with reference to FIGS. The package of cooked rice processed food of the present embodiment is a rectangular outer film 10 having a size capable of storing a lump processed rice cooked food (hereinafter referred to as “rice ball”) 2 like a triangular rice ball, as in the past. The two inner films 20 and 20 in which the inner ends 21 and 21 overlap each other on the line connecting the both ends 11a and 11b of the outer film 10 are sheet-like foods (hereinafter referred to as “nori”). 1), the peripheral edge 12 of the outer film 10 and the peripheral edges 22 and 22 of the inner films 20 and 20 are sealed.
[0020]
The inner ends 21 and 21 of the inner films 20 and 20 are usually overlapped on a center line connecting the center portions of both ends 11a and 11b of the outer film 10, but are overlapped on a line shifted from the center line. Also good.
[0021]
In addition, at both ends 21a and 21b of the inner ends 21 and 21 where the inner films 20 and 20 are overlapped, a notch for allowing separation when the two inner films 20 and 20 are pulled outward. 23, 23 are provided. As will be described later, the notches 23 and 23 are formed at both ends 21a of the inner ends 21 and 21 where the inner films 20 and 20 overlap when the peripheral portions 22 and 22 of the inner films 20 and 20 are sealed in a later step. , 21b and both ends 21a, 21b and the outer film 10 are not integrated so that the two inner films 20, 20 are separated from each other. It does not specify a circular shape.
[0022]
The outer film 10 and the inner films 20 and 20 are not specified as long as they are plastic films for food packaging, but it is preferable to use low-cost polypropylene with low air permeability. In addition, although not illustrated, the inner ends 21 and 21 where the inner films 20 and 20 overlap are folded outward to prevent the rice ball 2 from cracking when the inner films 20 and 20 are pulled outward. It may be.
[0023]
Moreover, the outer film 10 is good also as a composite material which joined and integrated the plastic material arrange | positioned at the inner surface side, and the paper quality material arrange | positioned at the outer surface side. The plastic material and the paper material are preferably bonded by heat, for example, but may be bonded by an adhesive. In any case, the outer paper-based material not only provides a high-class feeling, but also increases rigidity, so that the packaged rice ball 2 can be prevented from being crushed. As described above, polyethylene can be used as the plastic material in addition to polypropylene, and the paper material can be easily and reliably heat-sealed by using rayon paper having heat sealability. It can be carried out.
[0024]
And the package of the cooked rice processed food of this embodiment is provided with a pair of regulating members 13, 13 for regulating the tearing direction from one end 11a of the outer film 10 to the other end 11b, and both ends of the outer film 10 11a and 11b, and notches 14 and 14 are formed between the pair of regulating members 13 and 13, respectively. The notches 14 and 14 must be formed at the edges of both ends 11a and 11b of the outer film 10, but the end portions of the regulating members 13 and 13 are not only edges of both ends 11a and 11b of the outer film 10, but also edges. May be provided slightly inside.
[0025]
The notch 14 is for facilitating the tearing of the outer film 10, and when a force is applied to the outer film 10 in the width direction that separates both corners of the outer film 10, that is, in the direction perpendicular to the line. The outer film 10 is torn from the notch 14 as a starting point. When the notch 14 is formed at only one location at the center of each end 11a, 11b of the outer film 10 as shown in FIG. 1, the outer film 10 is divided into two parts, and each end 11a, 11b as shown in FIG. When two places are formed at a time, the outer film 10 is divided into three parts.
[0026]
Such a notch 14 is formed in the outer film 10 after the inner films 20 and 20 are three-side sealed in a subsequent process without specifying a shape such as a straight cut, a V-shaped cut, or a U-shaped cut. By doing so, it can form easily and reliably in the position which each end 11a, 11b overlapped.
[0027]
When the notch 14 is also formed on the inner film 20, the inner film 20 is also torn from the portion of the notch 14, and when the two inner films 20, 20 are pulled outward, the inner films 20, 20 are turned on. 2 and laver 1 may remain. However, since the notch 23 is provided in the inner film 20, the notch 14 can be formed only in the outer film 10. In other words, both when the notch 14 is formed at one place and when the notches 14 and 14 are formed at two places, the notches 23 and 23 are formed by the inner ends 21 and 21 of the inner films 20 and 20. It is provided over the overlapping width or more.
[0028]
On the other hand, the regulating member 13 for allowing the outer film 10 to be torn in a desired direction from the notch 14 is obtained by sticking a belt-like plastic film having a strength that does not cut even when pulled to the outer film 10. Alternatively, it may be made of uniaxially stretched plastic that does not tear in a certain direction.
[0029]
And when providing the notch 14 in two places, the direction where the intermediate | middle part 15 side by which the intermediate | middle outer film 10 is folded back in three when it is divided | segmented is wide space | interval is easy to grasp. Therefore, as shown in FIG. 2, the two strip-shaped regulating members 13 and 13 are laid out so that the width on each end 11a and 11b side is narrow and the width on the intermediate portion 15 side is wide. The outer film 10 and the inner films 20, 20 are made narrower in the notches 23 provided in the inner films 20, 20 in order to narrow the width on the side of each end 11 a, 11 b of the two regulating members 13, 13. , 23 is sealed, so that the outer film 10 and the inner films 20, 20 are strongly sealed, the notches 23, 23 can be provided as small as possible, and the interval between the notches 14, 14 can be shortened. It is because it is more preferable.
[0030]
However, when the notches 23 and 23 can be formed large in the width direction, the two strip-shaped regulating members 13 and 13 can be laid out in a wide parallel manner over the entire length. Further, in the case where the notches 14 are provided in two places, although not shown in FIGS. 2 to 5, it is preferable to provide another regulating member 13 for each regulating member 13. In this case, each notch 14 is sandwiched between two regulating members 13 and 13 having a narrow interval.
[0031]
In order to wrap the rice ball 2 with the packaged rice cooked food product of the present embodiment configured as described above, the bottom surface of the rice ball 2 is disposed in the middle of the inner films 20 and 20, and the front and back surfaces of the rice ball 2 are arranged. The outer film 10 and the inner films 20, 20 are folded in two so that the outer films 10 and 20 are joined to each other, and the peripheral edges of the inner films 20, 20 excluding the folded portions as shown in FIG. The peripheral portions 12 and 12 of the outer film 10 joined by the portions 22 and 22 and the notches 23 and 23 are joined, and the joined peripheral portions 22, 22, 12, and 12 are sealed by heat, for example.
[0032]
And in order to make it easy to peel off the peripheral parts 12 and 12 of the sealed outer film 10, it is preferable to make it weaker than the sticking force of the peripheral parts of the sealed inner films 20 and 20. For example, the adhesive force can be weakened by applying a part coat or the like to the peripheral portions 12 and 12 to which the outer film 10 is joined. It is sufficient to apply a part coat or the like to the peripheral portions 12 and 12 of the outer films 10 and 10, but for reasons such as manufacturing restrictions, the peripheral portions 22 and 22 of the inner films 20 and 20 that are continuous on both sides. 22 may be applied.
[0033]
And after sealing the peripheral edge parts 12 and 12 of the outer film 10 joined by the three peripheral edge parts 22 and 22 and the notch parts 23 and 23 of the inner films 20 and 20, the outer portions between the pair of regulating members 13 and 13 are sealed. Notches 14 and 14 are formed at both ends 11 a and 11 b of the film 10. Since the notches 23 and 23 are provided at both ends 21a and 21b of the inner ends 21 and 21 of the inner films 20 and 20, as described above, the notches 14 and 14 are formed in the inner films 20 and 20. There is nothing. Further, by forming the notches 14 and 14 at this stage, even if the peripheral portions 22 and 22 of the inner films 20 and 20 are displaced and sealed, the positions where the ends 11a and 11b of the outer films 10 and 10 are overlapped. The notches 14, 14 can be formed in
[0034]
In this way, the rice ball 2 is packaged with sufficient margin in the package, and can maintain a soft and soft feeling. Moreover, since the inner films 20 and 20 are interposed between the rice ball 2 and the laver 1, the laver 1 is transported or displayed without being damp.
[0035]
And in order to eat the rice ball 2, as shown in FIG. 4, the corners A and A of the three-side sealed package are picked and separated in the direction in which the corners A and A are separated. Then, the outer film 10 is torn along the regulating members 13 and 13 from the notches 14 and 14, and is divided into three as shown in FIG. Further, the notches 23 and 23 are provided at both ends 21a and 21b of the inner ends 21 and 21 of the two inner films 20 and 20, and the both ends 21a and 21b are not sealed. , 20 are pulled apart and pulled out from between nori 1 and rice ball 2.
[0036]
And since the notches 14 and 14 are formed only in the outer film 10 and are not formed in the inner films 20 and 20, the inner films 20 and 20 are not torn. Moreover, since both ends 21a and 21b of the inner ends 21 and 21 where the two inner films 20 and 20 overlap are provided with notches 23 and 23 and are not sealed, the two inner films 20 and 20 are laver. It is pulled out without remaining between 1 and Onigiri 2.
[0037]
And the intermediate | middle outer film 10 by which the both ends 11a and 11b side is sealed is the state which enclosed the rice ball 2 wrapped in the laver 1 as shown by the virtual line of FIG. Therefore, the seal is peeled off by inserting a finger into the sealed portion B and flipping it up. Since the part coat etc. are apply | coated to the said part B and the sticking force is weak, a seal | sticker can be peeled off easily. And since the corners of the square nori 1 protrude from the triangular rice ball 2, if necessary, wrap the protruding nori 1 softly and eat the sanitary food while picking the intermediate outer film 10 with one hand can do.
[0038]
The present invention is not limited to the embodiments of the invention, and can be variously modified within the scope of the technical matters described in the claims. In the embodiment of the invention, the outer film 10, the inner films 20, 20 and the laver 1 are formed in a rectangular shape, and the corners of the rectangular laver 1 are superimposed on the triangular rice ball 2. Therefore, in order to save the amount of laver 1 used, the laver 1 may be hexagonal as shown in FIGS.
