[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a packaging sheet for wrapped food used for packing so-called wrapped foods such as nigiri rice, nigiri sushi, rolled sushi, sandwiches, various confectioneries, or hamburger steaks.
[0002]
[Prior art]
Conventionally, there is known a packaging sheet 100 for packaging niboshi R0, which is a kind of encapsulated food as shown in FIG. As shown in FIG. 7A, the packaging sheet 100 has an outer film 110 formed of a thin transparent film made of a synthetic resin, having a rectangular shape in a developed state, with each corner being cut out. It has a basic configuration composed of the outer film 110 and the inner film 120 made of the same material, which are laminated on the outer film 110.
[0003]
The outer film 110 has a cut tape 111 attached to the inner surface side (the upper surface side in FIG. 7A) in the center in the width direction and extending over the entire length in the longitudinal direction. Also, a pair of cuts 112 are provided on both sides of the cut tape 111 at one short edge of the outer film 110, thereby forming a gripping piece 113 between the cuts 112 that can be gripped by a finger.
[0004]
The inner film 120 has a pair of width-wise half-split inner films 121 and 122 (a left half-split inner film 121 and a right-half split inner film 121) having a superposed portion 123 superposed along the cut tape 111 at a portion corresponding to the holding piece 113. It is composed of a half-split inner film 122).
[0005]
Then, in a state in which the inner film 120 composed of the half-split inner films 121 and 122 is laminated on the inner surface side of the outer film 110, these edges are welded in a ring shape while leaving the holding pieces 113, and the welding portion 130 (displayed in stippling). 7), a packaging sheet 100 as shown in FIG. 7A can be obtained.
[0006]
In a state where the sheet laver 140 is inserted into the packaging sheet 100 from the gap in the overlapping portion 123 of the left half inner film 121 and the right half inner film 122 of the packaging sheet 100, the lamination 140 is located at the center position on the inner film 120 side. As shown by the two-dot chain line in FIG. 7 (a), the rice noodles R0 are laid transversely in the width direction, the longitudinal ends of the packaging sheet 100 are folded to wrap the rice noodles R0, and stopped by spot welding. As shown in (b) of FIG. 7, the packaged food R1 with the sheet-like laver 140 in which the nigiri rice R0 is packaged by the packaging sheet 100 is completed.
[0007]
According to the packaged food R1, if the holding piece 113 is picked with a finger and the holding piece 113 is pulled in the direction of the arrow in FIG. Is cut such that the cut 112 is elongated, whereby the nigiri R0 is wrapped by the bisected outer film 110 and the originally split inner films 121 and 122. Then, if each of the bisected outer film 110 and each half-split inner film 121, 122 is opened and divided into left and right portions, the rice-like rice R0 in a state where the sheet-like laver 140 remains and is covered with laver is obtained.
[0008]
[Problems to be solved by the invention]
By the way, in the above-mentioned conventional packaging sheet 100, since the transparent film made of a synthetic resin is adopted as the outer film 110, the wrapped food inside (in the example of FIG. 7 the sheet laver 140) is used. Is seen through as it is, which presents a disadvantage that the packaged food R1 looks cheap.
[0009]
In order to solve such inconvenience, it is conceivable to use a material such as Japanese paper for the outer film 110. In this way, the nigiri rice R0 wrapped by the wrapping sheet is not directly visible from the outside, but since the paper material such as Japanese paper is strong, in order to enable one-touch unpacking using the cut tape 111, It is necessary to form perforations along the cut tape 111. However, if perforations are provided in the outer film 110, new problems such as moisture in and out of the package moistening the sheet-like laver N and unsanitary due to invasion of microorganisms are presented.
[0010]
The present invention has been made in order to solve the above-mentioned problems, and it is possible to effectively suppress the deterioration of the encapsulated food after giving the packaged food a luxurious feeling, and further facilitate the division. It is intended to provide a packaging sheet for encapsulated food.
[0011]
[Means for Solving the Problems]
The invention according to claim 1 is a wrapping sheet for wrapped food used for wrapping wrapped food, comprising a sheet body for wrapping wrapped food provided with a breaking means, The sheet body is formed by a pair of paper-like sheets including a paper material and a synthetic resin band-shaped film interposed between the pair of paper-like sheets, and the breaking means extends in a longitudinal direction of the film. As described above, the film is integrally laminated on the film.
[0012]
In the present invention, the breaking means is for assisting the separation of the sheet body, and is, for example, laminated on the back side of the sheet body in a band shape across the sheet body, and the tensile stress is larger than that of the sheet body. Generally, a tape made of a synthetic resin is used. By the presence of such a rupture means, by pulling the rupture means outward in a state in which the wrapped food is wrapped by the sheet body, both side portions of the rupture means in the sheet body are broken and rolled up in a band shape, thereby the sheet body And the packaged food can be easily taken out.
[0013]
In the present invention, the concept of a paper-like sheet body containing a paper material includes, of course, natural paper itself such as Japanese paper and so-called synthetic paper itself made of a cellulose derivative such as acetylcellulose. It also includes those obtained by laminating ordinary synthetic resin films on natural paper or synthetic paper.
[0014]
According to the present invention, the wrapped food packaged by the sheet body is covered with an opaque paper-like sheet on the outer surface, so that when the sheet body is transparent, the wrapped food is transparent and unsightly. In addition, the inconvenience of making the product look cheap is not only eliminated, but also the luxury is given, thereby increasing the commercial value of the packaged food.
[0015]
Moreover, a band-like film is interposed between the pair of paper-like sheet bodies, and the breaking means is integrally laminated on the band-like film. Therefore, the breaking means is guided outward by pulling the breaking means outward. Since it is divided, the pair of paper-like sheet members is easily divided right and left.
[0016]
According to a second aspect of the present invention, in the first aspect of the present invention, the sheet body is covered with an outer sheet made of the paper-like sheet and an inner surface laminated on the outer sheet being in direct contact with the outer sheet. A synthetic resin inner sheet body for wrapping the packaged food, wherein the inner sheet body is formed by a pair of inner sheet pieces separated so that their opposing edges overlap each other at the position of the breaking means. Is characterized in that the peripheral edge except the opposing edge is integrally connected to the peripheral edge of the outer sheet body.
[0017]
According to the present invention, the wrapped food is packaged in the packaging sheet so as to be in contact with the inner sheet body, so that the wrapped food is double wrapped by the inner sheet body and the sheet body, In addition to being hygienic, the invasion of microorganisms into the film is effectively suppressed, and the outside is covered with a transparent paper-like sheet, giving a sense of quality and increasing the commercial value.
[0018]
Then, in a state in which the sheet-shaped food is loaded between the inner sheet body and the outer sheet body, the outer sheet body is cut by the pulling operation of the breaking means, and then the cut pieces are separated right and left to separate the sheet. The packaged food is removed from the packaging sheet while being wrapped in the sheet food.
[0019]
Note that the packaging sheet of the present invention may be used in such a manner as to be packaged with an encapsulated food between the inner sheet body and the outer sheet body. When such a packaging method is adopted, the packaged food as a product may be displayed such that the outer sheet body is positioned on the upper side. By doing so, the outer sheet body can be made more conspicuous, so that the sense of quality of the packaged food is not impaired.
[0020]
According to a third aspect of the present invention, in the first or second aspect, the paper-like sheet body is made of a synthetic resin-made first film on the inner surface side and a paper material laminated on the first film. It is characterized by having a three-layer structure of an intermediate sheet body and a synthetic resin-made second film on the outer surface side laminated on the intermediate sheet body.
[0021]
According to the present invention, by overlapping the intermediate sheet made of paper material between the first film and the second film made of synthetic resin in close contact with each other while wrapping the wrapped food in the packaging sheet Can be subjected to a temporary fixing welding process, thereby facilitating the packaging process.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a partially cutaway perspective view showing a first embodiment of a packaging sheet 10 according to the present invention, and FIG. 2 is a sectional view taken along line AA. The packaging sheet 10 of this embodiment is for nigiri rice R0.
[0023]
First, as shown in FIG. 1, the packaging sheet 10 is formed in an octagonal shape by obliquely cutting out four corners of a rectangular shape in plan view. The wrapping sheet 10 includes an outer sheet body 20 positioned on the outer surface side in a state of wrapping the rice cake R0, and an inner film (inner sheet body) 30 laminated on the inner surface side (upper side in FIG. 1) of the outer sheet body 20. And a cut tape (breaking means) 40 laminated on the inner surface side of the outer sheet member 20 so as to extend in the longitudinal direction at the center portion in the width direction of the outer sheet member 20.
[0024]
The outer sheet member 20 includes a left sheet member 20a, a right sheet member 20b, and a band-shaped film 50 interposed between the sheet members 20a, 20b, each having a width slightly smaller than １ ／ of the width of the packaging sheet 10. It consists of Then, the band-shaped film 50 is subjected to welding or bonding in a state of being stretched between the inner surfaces (upper surfaces in FIGS. 1 and 2) of the opposing edges of the respective sheets 20a and 20b, so that the outer sheets 20 are formed. Is formed.
[0025]
At both ends of the band-shaped film 50, a pair of cut portions 24 in the width direction formed by cutting a predetermined size from the outer edge are provided, and a knob which can be picked by a finger between these cut portions 24. 25 are formed.
[0026]
In the present embodiment, each of the sheet bodies 20a and 20b is laminated by a predetermined coating process on the inner side of the first film 21 and the outer surface side (the lower side of FIGS. 1 and 2) of the first film 21. An intermediate sheet (paper-like sheet) 22 and a second film 23 laminated on the outer surface of the intermediate sheet 22 by a coating process.
[0027]
The first film 21, the second film 23, and the strip film 50 are formed of a thin film of a normal thermoplastic synthetic resin such as polyethylene or polypropylene, while the intermediate sheet body 22 is formed in a Japanese paper shape. In this case, a so-called rayon paper is used, and a woven pattern such as Japanese paper is formed on the front and back surfaces of the intermediate sheet body 22. This woven pattern can be seen through the second film 23 so that the packaging sheet 10 But to be rich.
[0028]
The reason that the intermediate sheet body 22 is sandwiched between the first film 21 and the second film 23 made of a usual thermoplastic synthetic resin is as follows. That is, when the wrapped rice R0 is wrapped in the wrapping sheet 10, as shown in FIG. 3, the front and back sides of the wrapping sheet 10 overlap each other (in an overlapping mode, the inner side of the outer sheet body 20 and the inner film 30 overlap, And there is an overlap between the outer surface side of the outer sheet member 20 and the inner film 30). Therefore, in order to prevent the package from being unraveled in such an overlapped state, it is necessary to perform spot welding on the overlapped portion. This is because it is necessary to laminate the first film 21 and the second film 23 made of a synthetic resin material that can be easily welded on the front and back of the intermediate sheet body 22 that is difficult to perform a typical welding process.
[0029]
Further, the second film 23 is subjected to a matting process on the surface side, and is made translucent by the matting process. As a result, the pattern on the surface of the intermediate sheet body 22 is visually recognized through the translucent second film 23, and a dim feeling is brought out, whereby the packaging sheet 10 becomes more luxurious. Become.
[0030]
The cut tape 40 is formed of a predetermined synthetic resin material that has been uniaxially stretched in the longitudinal direction, so that the tensile stress in the longitudinal direction is greater than the tensile stress in the width direction and is less likely to be torn. . The cut tape 40 is welded or bonded over the entire length in the longitudinal direction at the center position in the width direction on the inner surface side (the upper surface side in FIGS. 1 and 2) of the strip-shaped film 50.
[0031]
Therefore, the strip-shaped film 50 is guided by the cut tape 40 and the portions corresponding to the opposing edges of the left and right sheet bodies 20a and 20b are pulled by the finger and the cut piece 25 together with the cut tape 40. The outer sheet member 20 is broken and divided right and left.
[0032]
The inner film 30 is constituted by a pair of inner film pieces (inner sheet pieces) 30a and 30b (left inner film piece 30a and right inner film piece 30b) formed symmetrically to the left and right. Each of the inner film pieces 30a and 30b is set to have a width slightly larger than 幅 of the width of the outer sheet body 20, whereby the inner film pieces 30a and 30b are connected to the first film 21 of the outer sheet body 20. In a state of being overlapped on the side, an overlapping portion 31 extending in the longitudinal direction is formed at the center in the width direction.
[0033]
In a state where such an inner film 30 is laminated on the first film 21 side of the outer sheet body 20 provided with the cut tape 40 and the band-shaped film 50, these peripheral edges are subjected to a welding process, whereby FIG. And the packaging sheet 10 in which the welding zone 32 was formed in the peripheral part as shown in FIG. 2 is formed. In a state where the packaging sheet 10 is formed, a storage space 33 is formed between the outer sheet body 20 and the inner film 30, the periphery of which is closed by the welding band 32, and which has an opening in the overlapping portion 31. ing.
[0034]
In the present embodiment, the storage space 33 is loaded with sheet laver N as a sheet food. The sheet laver N is placed on the first film 21 in advance in the manufacturing process of the packaging sheet 10, and is subjected to the forming process of the welding zone 32 in this state so as to be loaded into the storage space 33. I have. However, instead of this, the laminating portion 31 may be opened after only the packaging sheet 10 is formed, and the sheet laver N may be inserted into the storage space 33 from here.
[0035]
The first film 21, the second film 23, the inner film 30, and the belt-like film 50 are formed of a thermoplastic synthetic resin having a relatively low softening point. Examples of the thermoplastic synthetic resin include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyamide (PA), polyvinylidene chloride (PVDC), and ethylene vinyl acetate prepared to have a predetermined softening point. A copolymer (EVA) or the like is preferably used.
[0036]
Further, as the intermediate sheet body 22, a synthetic resin commonly called rayon paper made of a so-called cellulose derivative such as acetylcellulose, acetic acid / cellulose nitrate, methylcellulose, ethylcellulose or carboxymethylcellulose is preferably used. In the manufacturing process of the intermediate sheet body 22 made of such a cellulose derivative, a predetermined treatment for imparting a drawing pattern is performed, so that the intermediate sheet body 22 can have a high-class feel.
[0037]
As the mat treatment, a sand blast method in which sand is sprayed on the surface of the second film 23, an etching mat method in which the surface of the second film 23 is etched with an alkali saponifying solution or an organic solvent, and a matting agent coated on the surface to form a mat. A matting agent coating method or a matting roll method in which the second film 23 is passed through a roll having a matte surface such as a matte pattern or a woven pattern can be used.
[0038]
In this embodiment, a mat roll method is employed. Specifically, the raw material of the second film 23 in the molten state is supplied to the surface of the intermediate sheet body 22 moving in the stretched state via a predetermined supply roll, and the material is laminated on the surface of the intermediate sheet body 22. Before the coating layer having a uniform thickness is solidified, the matte pattern on the surface of the mud roll is transferred to the second film 23 by a press treatment by dipping the coating layer into a rotating mud roll.
[0039]
FIG. 3 is a perspective view showing a state in which the nigiri rice R0 is wrapped by the wrapping sheet 10. As shown in this figure, the packaged food R1 formed by packing the rice stuffed rice R0 with the packaging sheet 10 has the matted second film 23 on the outermost side and the lower side thereof. Since the second film 23 formed with a woven pattern such as Japanese paper is present, it is less uncomfortable than the conventional packaging sheet 100 (FIG. 7) in which the contents can be seen through, and is blurred through the first film 21. As a result, the pattern of the intermediate sheet 22 is visually recognized, thereby providing an elegant and luxurious feeling.
[0040]
In addition, in the state where the rice nibble R0 is wrapped by the packaging sheet 10, there is a portion where the first film 21 and the second film 23 of the heat-weldable outer sheet body 20 overlap with the inner film 30. The overlapped portions are spot-welded to each other at appropriate places. By doing so, the inconvenience of unwrapping the packaging sheet 10 once wrapped with the rice noodles R0 is avoided.
[0041]
Further, as shown in FIG. 1, the left and right sheet members 20a and 20b are formed at the ends of the band-shaped film 50 because their opposed edges are connected by the band-shaped film 50 over the entire length in the longitudinal direction. By pulling the cut piece 25 and pulling the cut tape 40 outward, as shown by the two-dot chain line in FIG. The sheet 10 is divided into right and left.
[0042]
Then, by separating the left and right halves of the packaging sheet 10 in opposite directions in a state where the packaging sheet 10 is divided into right and left, the left inner film piece 30a originally composed of the two inner film pieces 30a and 30b and The right inner film piece 30b is also divided into left and right parts, and the packaging sheet 10 is pulled apart to the left and right, so that the inside rice cake R0 can be taken out.

(2) In the above-described first embodiment, the packaging sheet 10 is constituted by the outer sheet body 20 and the inner film 30 so that the dried sheet-like laver N is mounted, and a storage space 33 is formed therebetween. By loading the sheet-shaped laver N into the storage space 33, the moisture of the rice grind R0 is prevented from transferring to the sheet-like laver N, but from the beginning, the seaweed is rolled around the rice grip R0 and the seaweed becomes wet. When the seaweed is used to wrap wet-type rice cakes, the storage space 33 for storing the sheet-like seaweed N is unnecessary, so the inner film 30 is not particularly necessary. You may comprise a sheet.
[0056]
(3) In the above-described embodiment, a normal transparent synthetic resin film is used as the inner film 30 and the lower film 70, but instead of this, the inner film 30 (inner sheet body) and the lower film are used. A film using the same material as the outer sheet body 20 may be adopted as the film 70. By doing so, the packaging sheet gives the impression that it is entirely made of Japanese paper, and the luxury of the packaged foods R1 and R3 can be further enhanced.
[0057]
(4) In the above embodiment, the left and right sheet bodies 60a and 60b forming the upper sheet body 60 are divided into right and left over the entire length of the packaging sheet 11, but the present invention is applied to each sheet body 60a. , 60b is not limited to being divided into left and right as a whole, but a bifurcated shape in which the left and right intermediate sheet bodies 62 and the second film 63 are connected to each other via a bridging portion on the tip side of the transverse welding zone 72. It may be.
[0058]
【The invention's effect】
According to the first aspect of the present invention, the sheet main body has a pair of paper-like sheets including a paper material and a length substantially the same as the length of the paper-like sheets provided between the pair of paper-like sheets. Since it is configured with a synthetic resin band-shaped film having, the wrapped food packaged by the sheet body is in a state where most of the outer surface is covered by an opaque paper-like sheet, and the sheet body is entirely transparent. In such a case, all of the encapsulated food is transparent and unsightly, and the inconvenience of making the product look cheap is not only eliminated, but also the luxury is imparted, whereby the commercial value of the packaged food can be increased.
[0059]
Moreover, a band-like film is interposed between the pair of paper-like sheet bodies, and the breaking means is integrally laminated on the band-like film. Therefore, the breaking means is guided outward by pulling the breaking means outward. It is broken, and the pair of paper-like sheets can be easily divided right and left.
[0060]
According to the invention described in claim 2, the wrapped food is double-wrapped by the inner sheet body and the outer sheet body by being packaged with the packaging sheet so as to be in contact with the inner sheet body. As a result, hygiene is achieved in which the invasion of microorganisms into the packaging film is effectively suppressed, and the outside is covered with a paper-like sheet body, giving a sense of quality and increasing the commercial value.
[0061]
Then, in a state in which the sheet-shaped food is loaded between the inner sheet body and the sheet body, the outer sheet body is cut by the pulling operation of the breaking means, and then the broken pieces are separated to the right and left, thereby separating the sheet shape. The encapsulated food in a state of being wrapped in the food can be easily taken out of the packaging sheet.
[0062]
According to the third aspect of the present invention, the paper-like sheet body is laminated on the intermediate sheet body, the first synthetic resin resin film on the inner surface side laminated on the intermediate sheet body, and the intermediate sheet body. Because it was composed of a three-layer structure with a synthetic resin second film on the outer surface side, the packaging was achieved by tightly sandwiching a paper material intermediate sheet between the synthetic resin first film and the second film. In a state where the wrapped food is wrapped in the sheet, it is possible to perform a temporary fixing welding process on the overlapping portions, thereby facilitating the packaging process.
