Description

  The present invention relates to a food package packaged with a food packaging material.

  Food packaging materials for packaging food such as cooked rice foods such as triangular rice balls and the like whose front shape is triangular (mainly equilateral triangular) or a shape similar thereto and finished in a three-dimensional shape having a predetermined thickness are: A rectangular outer sheet in which a cut tape is provided along a longitudinal direction at a central portion in a width direction, and a pair of inner ends overlapped along the cut tape and overlapped with the outer sheet with a sheet-shaped food therebetween. In general, an outer sheet and an inner sheet are joined so as to surround a sheet-shaped food, and for example, a configuration described in Patent Document 1 is known.

  Such a food packaging material is folded in two in the longitudinal direction with the food in between, and the left and right extra sheet pieces are folded into the center side to form a substantially triangular shape, and the folded portions are point-sealed or affixed with a label. After that, the food is packaged.

  When eating the food in the food package, pull out the cut tape of the outer sheet, cut the outer sheet in the longitudinal direction, and then separate the left and right ear pieces formed at the bottom corners of the food package respectively. By pinching and pulling the pair of divided package pieces to the side, the food can be taken out and eaten in a state of being integrated with the sheet-shaped food.

  However, usually, the lug is formed by superimposing an extra sheet of food packaging material into a flat shape, and since it is the sheet material itself, the grip properties are poor. Rather, the surface of the ear piece may have an oil film derived from food or a manufacturing process, and may even be slippery. Therefore, there is a problem that the operation of pinching the left and right ear pieces and pulling the pair of divided package pieces to the respective sides cannot be performed smoothly, which may take time to open.

  Then, this invention was made in view of such a situation, and makes it a subject to provide the food package which can pinch the ear piece formed in a corner part firmly.

<First embodiment>
Hereinafter, as a first embodiment of the present invention, one embodiment of a food packaging material used for packaging a triangular rice ball and a food package packaged with the food packaging material will be described with reference to FIGS. 1 to 8. Will be explained.

  As shown in FIGS. 1 to 3, the food packaging material 1 according to the present embodiment includes a pair of sheets (an outer sheet 2 and an inner sheet 3) in which one of the directions orthogonal to each other is longer than the other. End pieces 11, 11 at one end and the other end in the longitudinal direction and side pieces 12 at both sides so as to surround the sheet food 4 so as to surround the sheet food 4, such as laver, which is wound on rice balls. , 12 with a main body 10 sealed on all sides. In the following, the one (the vertical direction in FIGS. 2 and 3) is referred to as a “longitudinal direction”, and the other (the horizontal direction in FIGS. 2 and 3) is referred to as a “width direction”.

  The outer sheet 2 is formed of a heat-welding plastic sheet such as polyethylene or polypropylene, and has a rectangular shape or a substantially rectangular shape (a rectangular shape or a substantially rectangular shape) large enough to wrap food in a state of being folded in two in the longitudinal direction. Have.

  The inner sheet 3 is also made of a heat-sealable plastic sheet such as polyethylene or polypropylene, and has a rectangular shape or a substantially rectangular shape large enough to wrap food in a state of being folded in the longitudinal direction. Further, the inner sheet 3 is composed of a pair of inner sheets 3 and 3 whose inner ends are overlapped along the longitudinal direction, and the size of the state where the inner ends are overlapped is the same size as the outer sheet 2. It is. In the present embodiment, the overlapping portion 30 of the inner ends of the inner sheets 3 and 3 is provided at the center or substantially the center in the width direction of the inner sheet 3.

  The end joining portion 11 heat-seals the outer sheet 2 and the inner sheet 3 along one end and the other end of the outer sheet 2 and the inner sheet 3 except for the overlapping portion 30 between the inner ends of the inner sheets 3 and 3. It is formed by doing. The side joint 12 is formed by heat sealing the outer sheet 2 and the inner sheet 3 along the side edges of the outer sheet 2 and the inner sheet 3. In the present embodiment, the side joints 12 are provided with communication portions 12a at appropriate intervals in the longitudinal direction so as to allow ventilation in the width direction, and the side joints 12 are divided into a plurality by the communication portions 12a. It becomes a divided form.

  The inside of the main body 10 configured in this manner serves as a storage portion for the sheet-shaped food 4, and one end of the outer sheet 2 is provided with a pair of cut lines 20, 20 spaced apart from each other with a predetermined interval in the width direction. Is formed. The cut line 20 is formed by a full cut line, a half cut line (half cut), a perforation, and the like. The formation of the cut line 20 forms a knob 21 as an opening start point. The opening guide means 5 is provided from the knob 21 to the other end of the outer sheet 2. The opening guide means 5 is, for example, a cut tape (opening strip) attached to the inner surface of the outer sheet 2, a pair of half cuts, a thread, or the like. Thus, when the knob 21 is pulled down, the opening guide means 5 cuts the outer sheet 2 at a predetermined width, and the outer sheet 2 can be separated in the width direction. In the present embodiment, the opening guide means 5 is provided at the center or substantially the center of the outer sheet 2 in the width direction, and overlaps the overlapping portion 30 at the inner end of the inner sheets 3 and 3.

  Notches 14 are formed at the four corners of the main body 10. The notch 14 is used to wrap the left and right extra sheet pieces toward the center by eliminating a part of the left and right extra sheet pieces when the food is packaged using the food packaging material 1. This is for reducing the overlap of the sheet pieces in forming a substantially triangular shape.

  The food packaging material 1 according to the present embodiment is configured as described above. Next, a food packaging method using the food packaging material 1 will be described.

  First, as shown in FIG. 4A, a triangular rice ball 6 is placed on the inner sheet 3 of the packaging material 1 for food. At this time, the triangular rice ball 6 is evenly placed on the overlapping portion 30 of the inner films 3, 3, and one corner of the triangular rice ball 6 faces the knob 21 on one end side of the food packaging material 1. So that the triangle rice ball 6 is arranged.

  Next, as shown in FIG. 3B, the food packaging material 1 is folded in two in the longitudinal direction so that one end and the other end opposite thereto are joined, and the folded part is a triangular rice ball 6. Fold along the side of the triangle (triangular slope). Thereby, one end half of the food packaging material 1 in the longitudinal direction covers the front of the triangular rice ball 6, the other half covers the rear surface of the triangle rice ball 6, and the left and right sheet pieces 15, Reference numeral 15 indicates a state where the positions of the one end and the other end of the food packaging material 1 are shifted.

  Then, as shown in FIG. 2C, one of the left and right extra sheet pieces 15 is folded and overlapped on the portion of the food packaging material 1 covering the back of the triangular rice ball 6, and the food packaging material 1 is placed thereon. Next, as shown in FIG. 5 (a), the other extra sheet piece 15 is folded and overlapped on the portion of the food packaging material 1 covering the back side of the triangular rice ball 6 to form a substantially triangular shape. .

  At this time, a plurality of sheets (in this embodiment, four sheets of the outer sheet 2 and four sheets of the inner sheet 3, a total of eight sheets) overlap each corner of the substantially triangular shape. Thus, a flat ear piece 16 is formed.

  Then, as shown in FIG. 2B, the portions of the left and right extra sheet pieces 15, 15 which are not overlapped by the cutout portion 14 are covered with the back surface of the triangular rice ball 6 of the food packaging material 1. Then, the food packaging material 1 is fixed in a state in which the triangular rice ball 6 is wrapped around by joining a point seal or the like to the existing portion (joining portion 17). Then, as shown in FIG. 1C, a label 7 is attached thereon. The shape of the joint is not limited to the circular shape as shown in the figure, but may be various shapes such as an ellipse, an ellipse, a polygon, and a line. The number of the joints is not limited to two. Instead, three or more places may be provided, or one large joint that is long in the width direction may be provided.

  As a result, the food package is completed for the time being, but in the present embodiment, the ear pieces 16 at the three corners are subjected to unevenness processing. More specifically, the ear pieces 16 of each of the three corners are formed by simply folding an extra sheet piece around an axis in the projecting direction of the ear pieces 16 and have a smooth surface. In order to increase the resistance in the direction, unevenness is applied to this.

  Various known methods can be used for the method of forming the unevenness. Here, the case of heat sealing using a sealer having an uneven surface will be described. As shown in FIGS. 6A and 6B, the resistance increasing portion 18 of each ear piece 16 of the food package is formed by a pair of sealers 100 and 101. This sealer includes a sealer 100 having a plurality of (three in the present embodiment) convex ridges 100a having a convex cross section at predetermined intervals, and a concave groove 101a having a concave cross section is the same as the convex ridge 100a. And a sealer 101 having a plurality of pitches (three in this embodiment).

  As a result, as shown in FIG. 7C and FIG. 7, each of the ear pieces 16 at the three corners of the food package becomes a ridge on one surface of the ear piece 16, and is opposite to the ear piece 16. A plurality of (three in the present embodiment) resistance increasing portions 18 forming concave grooves with respect to the surface of the ear piece 16 are formed at predetermined intervals in the protruding direction P of the ear piece 16, so that the entire ear piece 16 has an uneven shape. It becomes. In these drawings and in the following drawings, the height of the unevenness of the resistance increasing portion 18 is relatively large in order to easily understand the form of the resistance increasing portion 18. In the present invention, not only such a resistance increasing portion 18 but also one having a height of unevenness smaller than this can naturally be adopted.

  In the food package having the above configuration, when eating the triangular rice ball 6, as shown in FIG. 8 (a), the knob 21 is picked up, the opening guide means 5 is wrapped around, and the outer sheet 2 is lengthened. Split in the direction. At this time, the opening guide means 5 is formed of two cut tapes spaced from each other, so that a wide dividing opening can be formed. Thereby, after the outer sheet 2 is divided, the contact area between the outer sheet 2 and the sheet food 4 is reduced. Then, as shown in FIG. 3B, the pair of cut pieces of the packaging body are pulled sideways, whereby the triangular rice ball 6 can be taken out in a state of being integrated with the sheet-shaped food 6.

  At this time, since the entire ear piece 16 has an uneven shape due to the plurality of resistance increasing portions 18,..., Resistance is provided in the protruding direction of the ear piece 16, and the ear piece 16 is provided with a gripping property (non-slip property). Is done. With this, the left and right ear pieces 16 and 16 located on the bottom side of the food package are respectively picked, and when the pair of divided package pieces are pulled to the side, respectively, the ear pieces 16 and 16 are firmly picked. And opening operability can be improved.

  As described above, the ear pieces 16 at the three corners are folded around the axis in the direction in which the ear pieces 16 protrude, so that basically no openings are formed, but the folding is insufficient. The possibility of opening due to the elasticity of the folded or folded sheet cannot be denied. As a result, the inside and outside of the food package are in communication with each other, leaving room for foreign substances and the like to enter therefrom. However, according to the food package according to the present embodiment, the resistance increasing portion 18 is a seal line (sealing portion) formed in the width direction of the ear piece 16 that intersects with the protruding direction P of the ear piece 16. Since the sealing properties of the ear pieces 16 are improved, and moreover, a plurality of resistance increasing portions 18 are provided on each of the ear pieces 16, the joining strength of the resistance increasing portions caused by the thickness of the ear pieces 16 and mechanical variations. Even if a partial decrease occurs, high sealing performance can be maintained.

  Each of the resistance increasing portions 18 of the left and right ear pieces 16, 16 located on the bottom side of the food package body extends over the entire width of the ear piece 16 in the width direction of the ear piece 16 intersecting with the protruding direction P of the ear piece 16. Formed. Thereby, an extremely high sealing property can be obtained.

  On the other hand, each resistance increasing portion 18 of the lug 16 at the apex corner of the food package is located on the side of the knob 21 and the opening guide means 5 in the width direction of the lug 16 intersecting with the protruding direction P of the lug 16. (The edge of the ear piece 16 on the front side of the food package) is not formed. This is because if the resistance increasing portion 18 is formed extending to this side portion, the sheet near the knob 21 and the vicinity of the opening guide means 5 are integrated by joining, and the function of the knob 21 is impaired. This is because opening may be difficult.

<Second embodiment>
Next, a second embodiment of the present invention will be described with reference to FIGS. The difference from the first embodiment is only the position and the structure of the opening start point, and the other structures are the same, so that the description of the same structure is omitted.

  As shown in FIGS. 9 to 11, a cut line 20 composed of a full cut line is formed on the opening guide means 5 at a position closer to the center in the longitudinal direction than one end of the outer sheet 2. As shown in FIG. 12, the cut line 20 is formed in the width direction of the food packaging material 1 with the first all-in line 20 a intersecting a portion other than the end of the opening guide means 5 and the opening guide means 5 interposed therebetween. And a pair of second cut lines 20b, 20b, each of which is separated from each other at a predetermined interval and intersects with the first all-in line 20a at a portion other than the end portion. As a result, the opening guide means 5 is cut off by the first all-cut line 20a, and the first all-cut line 20a and the pair of second cut lines 20b and 20b are separated from the first all-cut line 20a. A notch piece 21 having the other end side portion of the sheet 2 as an outline is formed as an opening start point. In the present embodiment, the end of the first cut line 20a and the intermediate portion of the second cut line 20b intersect, so that the cut line 20 has an H character shape.

  Since the inside and outside of the outer sheet 2 communicate with each other due to the formation of the score line 20, and there is room for foreign matter and the like to enter therefrom, the score line 20 is covered by the covering sheet 8 arranged on the inner surface of the outer sheet 2, The inside and outside of the outer sheet 2 are shielded. The covering sheet 8 is joined to the inner surface of the outer sheet 2 by heat sealing or the like so as to surround the cut line 20 (joining portion 22), and airtightness is maintained.

  The opening operation piece 9 is arranged on the outer surface of the outer sheet 2 so as to contact at least the cut piece 21. The opening operation piece 9 includes a main body 9a having an adhesive surface or an adhesive surface that is removably adhered or adhered to the outer sheet 2, and a knob 9b extending from the main body. The main body 9 a is attached to the outer surface of the outer sheet 2 so as to cover the cut line 20. The knob 9b extends from the main body 9a to one end of the outer film 2 and is a free end. In the present embodiment, the main body 9a is formed to be sufficiently larger than the cut line 20 in order to provide a region for displaying the product name and product information of the food package and the design related thereto. . Thereby, the opening operation piece 9 also functions as a label.

  As shown in FIG. 13, the cut line 20 and the knob 9b of the opening operation piece 9 are located at or near the vertex of the food package in the state of the food package. And since this opening starting point is not in the ear piece 16 at the apex corner but in the packaging area of the food 6, the ear piece 16 at the apex corner has the front face of the food package as in the first embodiment. It is not necessary to avoid providing the resistance increasing portion 18 at the side edge. Therefore, in the present embodiment, each of the ear pieces 16 at the three corners of the food package is disposed at predetermined intervals in the protruding direction P of the ear pieces 16 (in the present embodiment, three or more pieces are arranged). Are formed over the entire width of the lug 16. Thus, extremely high sealing performance can be obtained in any of the ear pieces 16.

  When eating the triangular rice ball 6 in the food package having the above configuration, as shown in FIG. 14A, the user grips the knob 9b of the unsealing operation piece 9 and draws it around in a vertical direction. Then, since the opening guide means 5 separated by the first all cut line 21a of the cut line 21 is attached to the opening operation piece 9, the opening guide means 5 cuts the outer sheet 2 in the longitudinal direction. become. In this state, a portion where the outer sheet 2 has not yet been divided remains at the top corner of the food package. However, a portion of the second cut line 20b of the cut line 20 closer to one end of the outer sheet 2 than the first all cut line 20a (a portion facing the tip of the vertex corner) remains in the apex corner. This is the opening starting point toward the tip of the vertex. Therefore, as shown in FIG. 3B, the pair of divided pieces of the package are pulled sideways around the top corners of the food package to thereby integrate the triangular rice ball 6 with the sheet-like food 4. It can be taken out in the state of being converted.

  As described above, also in the food package according to the present embodiment, the entire ear piece 16 has an uneven shape due to the plurality of resistance increasing portions 18,. The piece 16 is provided with a gripping property (anti-slip property). With this, the left and right ear pieces 16, 16 located at the bottom side of the food package are respectively picked, and when the pair of divided package pieces are pulled to the respective sides, the ear pieces 16, 16 are firmly picked. And opening operability can be improved.

  Further, according to the food package according to the present embodiment, since the resistance increasing portion 18 is a seal line (sealing portion) formed in the width direction of the ear piece 16 that intersects with the protruding direction P of the ear piece 16. Since the sealing properties of the ear pieces 16 are improved, and moreover, a plurality of resistance increasing portions 18 are provided on each of the ear pieces 16, the joining strength of the resistance increasing portions caused by the thickness of the ear pieces 16 and mechanical variations. Even if a partial decrease occurs, high sealing performance can be maintained. Moreover, the ear piece 16 at the apex corner of the food package also has the resistance increasing portion 18 formed over the entire width of the ear piece 16 like the other ear pieces 16, so that all the ear pieces 16 have the same resistance. High sealing performance can be maintained.

  Note that the food packaging material and the food package according to the present invention are not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.

  For example, in the above embodiment, the three ear pieces 16,... Are provided with the resistance increasing portions 18, respectively, but the present invention is not limited to this. For example, if only the improvement of the openability of the food package is considered, as shown in FIG. 15A, the resistance increasing portion 18 is provided only on the left and right ear pieces 16, 16 located at the bottom of the food package. May be. In addition, the resistance increasing portion 18 provided on the ear piece 16 at the apex of the food package enhances the grip when the ear piece 16 is picked up. It is useful as a holding part when displaying a food package and has no food packaging area, so it is hygienic. However, if only this viewpoint is considered, as shown in FIG. Alternatively, the resistance increasing portion 18 may be provided only on the ear piece 16 at the vertex of the food package.

  Even if only the respective viewpoints are taken into consideration, the sealing performance can be obtained by providing the resistance increasing portions 18 on all the ear pieces 16, so that, for example, as shown in FIG. Although the number is smaller than that of the resistance increasing portions 18 of the left and right ear pieces 16 and 16 located on the left side of FIG. As shown in the figure, although the number is smaller than the resistance increasing portion 18 of the ear piece 16 at the top corner of the food package, the resistance increasing portion 18 is also provided on the left and right ear pieces 16, 16 located at the bottom side of the food package. You may do so.

  Further, in the above-described embodiment, the resistance increasing portion 18 is formed by pressing the unevenness, but the form of the resistance increasing portion 18 is not limited to this. In short, various forms can be adopted for the resistance increasing portion as long as the resistance increasing portion has a resistance portion in which the finger is hooked in the protruding direction P of the ear piece 16. As an example, as shown in FIG. 17A, the ear piece 16 may not only be convex on one surface but also convex on the other surface. As shown in the figure, the ear piece 16 may be embossed so as to form irregularities not only in the protruding direction of the ear piece 16 but also in the width direction, or as shown in FIG. It is also possible to fold a part of the piece 16 and use the end of the folded piece as a resistance increasing portion, or to pick up a part of the ear piece 16 to form a fold and use the fold as a resistance increasing portion. Good.

  Next, still another form of the resistance increasing section 18 will be described. FIG. 18 shows an example. In FIG. 1A, two types of sealing portions 18 are formed: a first sealing portion 18A formed by heat sealing, and a second sealing portion 18B formed by heat sealing in a lattice shape. The first sealing portion 18A is formed on the base end side of the ear piece 16, and the second sealing portion 18B is formed in the protruding direction P of the ear piece 16 across the non-sealing portion, FIG. The second sealing portion 18B is formed in a plurality in the protruding direction P of the ear piece 16 with the non-sealing portion interposed therebetween. FIG. 3C shows the first sealing portion 18A without the non-sealing portion. (D) to (f) corresponding to FIGS. (A) to (c) correspond to FIGS. (A) to (c) in which the lattice of the second sealing portion 18B is formed. (G) to (i) of FIG. 7 (g) to FIG. ) To correspond (c), the second sealing portion 18B is not a lattice form, shows an embodiment comprising a dot shape. In forming the lattice shape or the halftone dot shape of the second sealing portion 18B, the second sealing portion 18B is formed by forming the second sealing portion 18 so that the surface of the ear piece 16 has irregularities. As a mode, it becomes a resistance increase part (with 18 A of 1st sealing parts).

  Further, in the above embodiment, the food was a triangular rice ball (processed cooked rice food), and the sheet food was laver. However, the food may be an onigiri, sushi, sandwich, or the like having a shape other than the triangle as long as it can be packaged with the food packaging material, and the type and shape of the food are not limited. The sheet-like food may be a sheet-like kelp, tatami sardine, or the like as long as it can be accommodated in the planar accommodation portion of the food packaging material, and the type and shape of the sheet-like food are not limited.
