  Then, this invention makes it a subject to provide the food packaging body which enabled it to open without pressing a foodstuff, maintaining a sealing performance.

  In order to solve the above problems, the present invention takes the following technical means.

  The food packaging body of the present invention is a food packaging body in which a food 4 is housed in a bag 3 composed of a film 2 in which a cutting tape 1 for opening is bonded to the inner surface by a first surface 1a. Crosses the adhesive part 5 between the films 2 formed by heat sealing, and the second surface 1b of the cut tape 1 at the intersection A is the side facing by the heat sealing when the adhesive part 5 is formed. The bag 3 is releasably adhered to the inner surface of the bag 3 so that the sealing performance is maintained.

  Further, the cut tape 1 is provided so as to extend in the front-rear direction of the film 2, and the left end portion 20 and the right end portion 21 of the film 2 are bonded to form a cylinder, and the front end and the rear end thereof are opposed to each other between the left and right ends. Thus, the bag 3 can be formed by providing the bonding portions 5, 7, and 8 to which the inner surfaces are bonded, and the cut tape 1 can intersect with at least one of the bonding portions 5, 7, and 8.

  Alternatively, the cut tape 1 is provided so as to extend in the left-right direction of the film 2, and the left end portion 20 and the right end portion 21 of the film 2 are bonded to the inner surfaces of the film 2 that cross the cut tape 1 and face each other across the front and rear ends. The film 2 is formed into a cylindrical shape by providing 5, and the bag 3 is configured by providing adhesive portions 9 and 10 in which the inner surfaces facing each other across the left and right ends are bonded to the vicinity of the front end and the vicinity of the rear end, respectively. can do.

  The food packaging body of the present invention has the above-described configuration, and the adhesive portion 5 between the films 2 formed by heat sealing and the cut tape 1 intersect, but the cut tape 1 at the intersection A The second surface 1b is also adhered to the inner surface of the film 2 on the opposite side by heat sealing, so that the hermeticity is maintained, and the food 2 is not compressed by tearing the film 2 with the cut tape 1. It can be opened easily.

  Preferred embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a plan view of a film 2 with a cut tape used for the food packaging body according to the first embodiment of the present invention, and FIG. 2 shows a case where the food 4 is put inside the film 2 to form a cylinder. 3 is a rear view of the food packaging body, FIG. 4 is a front view of the food packaging body, FIG. 5 is an explanatory view showing the state of opening the food packaging body, and FIG.

  This food packaging body is a food packaging body in which a food 4 is housed in a bag 3 composed of a film 2 in which a cutting tape 1 for opening is bonded to the inner surface by the first surface 1a, and the cutting tape 1 is heated. Crossing the adhesive part 5 between the films 2 formed by the seal, and the second surface 1b of the cut tape 1 at the intersection A is a bag on the opposite side by heat sealing at the time of forming the adhesive part 5. It is assumed that the inner surface of 3 is releasably bonded so that the sealing performance is maintained.

  In the first embodiment of the food packaging body, the cut tape 1 is provided so as to extend in the front-rear direction of the film 2, and the left end portion 20 and the right end portion 21 (portion outside the broken line in FIG. 1) are bonded. Then, a bag 3 is formed by providing a bonding portion 5 in which the inner surfaces facing each other across both the left and right ends are bonded to the vicinity of the front end and the vicinity of the rear end, respectively, and the cut tape 1 is attached to the bonding portion 5. It is assumed that it intersects with at least one. For convenience of explanation, the front-rear direction is the vertical direction in FIG. 1, and the front end of the film 2 is the upper end of the film 2 in FIG.

  This food packaging bag 3 is formed from a single film 2 with a cut tape as shown in FIG. The film 2 is made of OPP (biaxially oriented polypropylene) with a thickness of 30 μm and has a rectangular shape with a width of about 310 mm and a length of about 270 mm. The film 2 has at least an inner surface having heat sealability. Specifically, it may have a copoly (copolymer) type seal layer on the inner surface side and a homotype (homopolymer) layer on the outer surface side.

  The cut tape 1 has a width of about 5 mm and is a thin strip extending across the front and rear ends of the film 2. Moreover, as for the cut tape 1, both surfaces (1st surface 1a and 2nd surface 1b) shall have heat-sealing property. Specifically, as shown in FIG. 6, two sheets of OPP having a thickness of 30 μm composed of two layers of a copoly type sealing layer 10 capable of heat sealing and a homotype layer 11 having no heat sealing property. The tape may be formed by bonding the homo-type layers 11 with the adhesive 12 so that the copoly-type seal layer 10 appears on the front and back sides as the first surface 1a and the second surface 1b.

  The cut tape 1 is bonded by heat sealing the first surface 1 a to the inner surface of the film 2. The position of the cut tape 1 can be changed as appropriate, and is not limited to the center position of the film 2 as shown in FIG. Moreover, the cut tape 1 and the film 2 may be transparent, or may be appropriately colored or provided with characters or designs.

  The film 2 with the cut tape can be easily mass-produced by first forming a long film in the front-rear direction and then cutting it in the transverse direction at a predetermined interval to form the above dimensions. . In this case, the film 2 before cutting may be wound in a roll shape.

  The film 2 is provided with an opening operation piece 6 by forming a vertically U-shaped cut across the cut tape 1 at an interval of about 1 cm from the center front edge. The cut penetrates the film 2 and the cut tape 1.

  In order to form the bag 3 with the film 2, as shown in FIG. 2, the left and right ends 20, 21 of the film 2 are bent so that the inner surfaces of the ends 20, 21 are bonded together by heat sealing. And make it cylindrical. Before bonding the left and right ends 20 and 21 of the film 2, the food 4 may be stored as shown in the figure, but the food 4 may be stored after the bonding.

  And the adhesion part 5,7,8 which the mutual inner surface which opposes between both right-and-left both ends adhere | attached on each of the front end vicinity of the cylindrical film 2 and rear end vicinity, and the foodstuff 4 is accommodated between front and back both ends. By forming the sealed portion, the bag 3 as shown in FIGS. 3 and 4 is formed. FIG. 3 is a view showing a state in which the inner surfaces of the left and right end portions 20 and 21 of the film 2 are heat-sealed, and the surface on which the operation piece 6 for opening is provided is on the front side. It is a figure which shows the state which carried out. In this embodiment, the side shown in FIG. 4 is the front side of the bag 3, and the side shown in FIG. 3 is the back side of the bag 3. However, either side may be the front side or the back side.

  In addition, the right end part 21 of the film 2 is bent so that the left end part 20 overlapping thereover appears as shown in FIG.

  In this embodiment, two adhesive portions 5 and 7 are provided in parallel near the front end of the bag 3, and one adhesive portion 5 intersects the cut tape 1 in a cross shape slightly inside the front end edge of the bag 3. The other adhesive portion 7 is located at the front end edge of the bag 3. The adhesive portions 5 and 7 in the vicinity of the front end each have a width of about 2 mm, and the opening operation piece 6 is positioned with an interval of about 10 mm between the adhesive portions 5 and 7. .

  The one adhesive portion 5 is formed by adhering the inner surfaces of the film 2 on the front side and the back side of the bag 3 by heat sealing, but at the location A that intersects the cut tape 1, the front side and the back side of the bag 3. The inner surfaces of the films 2 are not directly bonded to each other. However, since the second surface 1b (the surface not bonded to the inner surface of the film 2 on the front side) of the cut tape 1 has a heat sealing property, it intersects with the bonding portion 5 during the heat sealing process. The 2nd surface 1b in the location A adhere | attaches the inner surface of the film 2 of the back side of the bag 3 which opposes.

  Therefore, even if there exists the location A which cross | intersects the cut tape 1, the adhesion part 5 will be in the state heat-sealed continuously between the right-and-left both ends of the bag 3, and high sealing performance will be acquired.

  The other adhesive portion 7 is overlapped with the cut tape 1 in a T-shape, but, like the one adhesive portion 5, is continuously heat sealed across the left and right ends of the bag 3. Note that the front end side of the cut tape 1 is formed short so that the cut tape 1 does not overlap with the other adhesive portion 7, and the other adhesive portion 7 is formed between the left and right ends of the bag 3 so as to achieve higher sealing. You may make it get sex.

  Further, the adhesive strength of the other adhesive portion 7 may be stronger than that of the one adhesive portion 5. In this case, a high sealing strength is obtained by the strong adhesive strength of the other adhesive portion 7 and the adhesive strength of the one adhesive portion 5 is weak, so that the film on the back side of the bag 3 is cut with a relatively small force. Since it is made to peel from the inner surface of 2, the opening becomes very easy. It is also possible to omit the other adhesive part 7 and carry out.

  The bonding portion 8 near the rear end of the bag 3 has a width of about 15 mm at the rear end edge. In addition, you may make it accommodate the foodstuff 4 inside the bag 3 just before forming the adhesion part 8 near this rear end.

  When opening the food package, the opening operation piece 6 is pinched with a finger and pulled to tear the film 2 from the front end side toward the rear end side as shown in FIG. The cut tape 1 is bonded to the inner surface of the film 2 on the back side of the bag 3 at the intersection A with the bonding portion 5, but is peeled off at the time of tearing so as not to hinder the opening operation. When storing relatively long confectionery breads, sushi rolls, etc., tear the film 2 halfway to expose only the portion to be eaten to the outside of the bag 3 and not to expose the remaining portion. it can.

  Since the opening operation piece 6 is located outside the sealed portion between the bonding portion 5 and the bonding portion 8 in the bag 3, the opening operation piece 6 impairs the sealing performance of the bag 3 before opening. There is nothing.

  FIG. 7 is a front view of a food packaging body according to a second embodiment of the present invention. This food packaging body is provided with one adhesive portion 5 that intersects with the cut tape 1 near the front end and the rear end of the bag 3, and at the front and rear outer sides of the adhesive portions 5 of the film 2 on the front side of the bag 3, The opening operation piece 6 is formed by providing two cuts on the left and right sides of the front and rear ends of the cut tape 1. Other configurations can be the same as those in the first embodiment. The food package of the second embodiment can be opened from either the front end side or the rear end side of the bag 3.

  FIG. 8 is a front view of a food packaging body according to a third embodiment of the present invention, FIG. 9 is a rear view thereof, and FIG. 10 is a cross-sectional view in the vicinity of an intersection A between the cut tape 1 and the film 2. This food packaging body according to the third embodiment is provided with the cut tape 1 extending in the left-right direction of the film 2 and intersects the left end 20 and the right end 21 of the film 2 across the cut tape 1 and across both front and rear ends. The film 2 is formed into a cylindrical shape by providing an adhesive portion 5 to which the inner surfaces are bonded, and adhesive portions 9 and 10 that are bonded to each other between the left and right ends are provided in the vicinity of the front end and the vicinity of the rear end. Thus, the bag 3 is configured.

  The right end portion 21 of the film 2 is bent so that the left end portion 20 overlaps with it as shown in FIG. In FIG. 10, the left end 20 and the right end 21 of the film 2 are shown raised.

  The cut tape 1 is provided in a circumferential direction in the vicinity of the center in the front-rear direction of the bag 3, and two films 2 are provided on both sides of one end of the cut tape 1 outside the adhesive portion 5. The opening operation piece 6 is formed by providing a slit. As shown in FIG. 9, when the left end portion 20 of the film 2 overlaps the right end portion 21, the opening operation piece 6 may be provided on the left end portion 20. Since the left end 20 and the right end 21 of the film 2 are not bonded at the location where the opening operation piece 6 is provided, the film 2 can be easily torn from the opening operation piece 6.

  This food packaging body according to the third embodiment can be opened so as to divide the bag 3 back and forth by tearing the cut tape 1 in the left-right direction. The material, structure, etc. of the film 2 and the cut tape 1 can be the same as those in the first embodiment.

  The above is a preferred embodiment of the present invention, but the present invention is not limited to the configuration of the above-described embodiment, and can be implemented by appropriately changing the material, shape, dimensions, and the like.
