Description

  The present invention relates to a food packaging bag suitable for packaging foods such as handmade sandwiches, waffles, rice balls, etc., in particular, so that it can be sealed in an inflated state by filling the inside with air so that external force is not easily transmitted to the contained food. It relates to technology.

  The packing bags for sandwiches and confectionery breads sold as products at stores are filled with air to inflate the sandwiches and confectionery breads that are contained in the products to prevent external force from being applied during product transportation. In the state, the outer edge is heat-sealed and sealed.

  In a factory that manufactures such foods, the film, which is the material for the packaging bags, is formed into a bag shape while being sent out with a roller, the food is contained inside, heat-sealed around it, cut out individually, and shipped In the heat sealing process, the bag is filled with air or the like and inflated and sealed.

  However, when a sandwich is made at home, for example, it cannot be wrapped with a heat-sealing machine like a product, and it can be understood that it is made at home, so it may be embarrassing to eat in public.

  Moreover, it is possible to divert a bag with a zipper as a bag which can package food while being filled with air at home. The bag with a fastener is disclosed by the following patent document 1, for example.

JP-A-2005-271968

  However, when a zippered bag is used, it is necessary to open the zipper and put food in, close the zipper, leaving a part of the zipper, and feed air from the slightly opened part. is there. Also, such a zippered bag is premised on reuse and is made of strong and soft polyethylene, so the bag unit price is high, and it cannot be opened by tearing from the end like a commercially available bag.

  The present invention solves this problem and is a packaging bag that contains foods such as sandwiches, bread, waffles, and rice balls made at home, and it swells by filling the interior with air without using special equipment. An object of the present invention is to provide a food packaging bag that can be sealed in a state, can be easily opened, and can be manufactured at low cost.

In order to achieve the above object, a food packaging bag according to claim 1 of the present invention comprises:
A bag body (21) made of a film material, the outer periphery of which is closed except for one side (21a) serving as an opening for receiving food inside,
The opening has a predetermined width and is substantially equal to the one side that becomes the opening, and is spaced parallel to the one side that becomes the opening and at least twice the predetermined width from the one side that becomes the opening. A double-sided adhesive tape (22) having one surface attached to the surface of the bag body,
After the food is received from the opening of the bag body, the double-sided adhesive tape is obtained by folding a plurality of portions from the one side to the double-sided adhesive tape from one side to the double-sided adhesive tape after the food is received. By adhering to the surface, the air can be sealed in a state where the air on the opening side is moved to the inside of the bag body.

The food packaging bag according to claim 2 of the present invention is the food packaging bag according to claim 1,
The bag body is formed of a film material having a structure that can be torn inwardly from the outer periphery.

The food packaging bag according to claim 3 of the present invention is the food packaging bag according to claim 1 or 2,
Folding marks (23, 24) are displayed in a region from the one side that becomes the opening to the double-sided adhesive tape.

  Since the food packaging bag according to claim 1 of the present invention is configured as described above, food such as sandwiches and rice balls made at home is put into the bag body from the opening, and the opening It is possible to seal food with air filled inside by folding it multiple times in the direction of double-sided adhesive tape from one side, and taking it out with the same feeling as a commercially available sandwich or rice ball etc. can do.

  Further, in the food packaging bag according to claim 2 of the present invention, since the bag body is formed of a film material having a structure that can be torn inwardly from the outer periphery, the contained food can be easily taken out in the same manner as a commercially available product. You can eat.

  Moreover, in the food packaging bag according to claim 3 of the present invention, since the mark for folding is displayed in the region from the one side portion serving as the opening to the double-sided adhesive tape, the bag is sealed in a state where the inside is filled with air. Work can be easily and reliably performed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a food packaging bag 20 to which the present invention is applied.

  The food packaging bag 20 includes a bag body 21 formed in a bag shape with a film material and a double-sided adhesive tape 22 attached to the bag body 21.

  The bag main body 21 is an opening for accommodating an article among the upper side portion 21a, the left and right side portions 21b and 21c, and the lower side portion 21d constituting the four sides of the two rectangular sheets. It has a structure in which the other outer periphery is closed except for the upper side portion 21a which is one side portion.

  The bag body 21 is formed by, for example, thermocompressing both ends of a rectangular film made of polypropylene (PP) to form a cylindrical shape with both upper and lower ends opened, and further pressing the whole thinly while thermocompressing the lower end side. It can comprise so that an upper side part side may become an opening part.

  Further, the structure of the bag body 21 is not limited to the above example, and a rectangular film material is folded in half at the center line, and both side edges thereof are thermocompression bonded, or two film materials having the same outer shape are formed. In an overlapped state, the entire outer peripheral edge may be thermocompression-bonded, leaving only the upper side portion serving as an opening for receiving.

  On one side of the bag body 21, a double-sided adhesive tape 22 having a predetermined width W and a length L substantially equal to the upper side part 21a of the bag body 21 is parallel to the upper side part 21a and at least a predetermined width W from the upper side part 21a. Is pasted with a gap G of at least twice (three times in this example). One side of the double-sided adhesive tape 22 is bonded to the bag body 21, and the opposite side (front side) is covered with a release paper 22a.

  In addition, on the surface of the bag body 21, a plurality of (two in this example) lines 23 and 24 serving as marks for folding are formed in the region from the double-sided adhesive tape 22 to the upper side portion 21a of the bag body 21 with the tape width W. They are displayed in parallel at approximately equal intervals.

  Moreover, the film material which comprises the bag main body 21 is a structure which can be torn from the outer periphery to the inside by hand, that is, a uniaxially stretched film which is made of polypropylene (PP) and can be torn in a uniaxial direction, or can be torn in a biaxial direction. The biaxially stretched film is formed, and incisions 27 and 27 are provided in a part of the outer periphery (in this example, the lower side portion 21d of the mating portion subjected to thermocompression bonding) so that the film can be easily cut.

  When food such as a handmade sandwich or rice ball is stored in the food storage bag 20 configured as described above, the opening of the upper side portion 21a is opened as shown in FIG. 2 and folded at the position of the line 23 (at this time, the end of the upper side portion 21a overlaps the line 24).

  Next, as shown in FIG. 2C, the folded portion (single folded portion) is further folded inward at the position of the line 24. At this time, the end of the folded portion (double folded portion) is close to the upper edge of the double-sided adhesive tape 22.

  Finally, in a state where the release paper 22a of the double-sided adhesive tape 22 is peeled off (may be peeled off first), as shown in FIG. 2 (d), the double folded portion is further folded to the double-sided adhesive tape 22 side. The adhesive tape 22 is superposed on the adhesive surface and adhered.

  In this way, by folding a plurality of times from the upper side portion 21a with the opening closed toward the inside, the air E in the upper side portion 21a moves to the inside of the bag body 21, and the bag E is filled with the air E, and The inside of the air is difficult to escape by being folded three times, and the folded portion is adhered to the double-sided adhesive tape 22 so that the inside can be sealed in a state of being filled with air. Can prevent crushing.

  And when eating this food F, as shown in FIG. 3, if the notch 27 on the outer periphery of the bag body 21 is torn by hand, the bag is broken and the food F can be taken out.

  Thus, if the food storage bag 20 of the embodiment is used, the food can be sealed in a state filled with air without using a special instrument and at a low cost, with almost the same feeling as a commercially available product. Can be handled. Further, if a film material having a structure capable of tearing the bag body from the outer peripheral edge is used, the contents can be taken out by a simple operation close to a commercially available product.

  Moreover, as long as the mark of folding is displayed between the upper side part 21a used as an opening part and the double-sided adhesive tape 22 like the said Example, anyone can seal in the state filled with air reliably.

  In the above-described embodiment, the outer shape of the bag main body 21 is an example of a rectangle, but the outer shape of the bag main body 21 can be variously modified according to the outer shape of the food to be stored.

  For example, when accommodating a triangular food F such as a rice ball, as shown in FIG. 4 (a), an external pentagon (base type) having a triangular part necessary for accommodation and a rectangular part necessary for folding. ), The food F is inserted from the upper side 21a which becomes the opening of the bag main body 21 to the triangular portion, and the rectangular portion is folded from the upper side 21a side with the lines 23 and 24 as marks as described above. By adhering to the double-sided adhesive tape 22, the food F can be sealed in a state where the triangular bag as a whole is filled with air as shown in FIG. 4B.

  When a semicircular food F is to be accommodated, as shown in FIG. 5 (a), a semi-oval bag body 21 having a semicircular portion necessary for the accommodation and a rectangular portion necessary for folding is provided. The food F is inserted from the upper side 21a serving as the opening of the bag main body 21 to the semicircular portion, and the rectangular portion is folded from the upper side 21a with the lines 23 and 24 as marks, as shown in FIG. As shown in (b), the food F can be sealed in a state where the semicircular bag is filled with air as a whole.

  The notch 27 provided in the above-described embodiment is provided, for example, at the overlapping portion of the outer edge of the bag body 21 that is thermocompression bonded. However, since the bag body 21 itself has a tearable structure, Even if the notch 27 is not present, the inner food F can be taken out from the outer edge.

  Further, the folding marks may be indicated not only by the lines as described above but also by marks or the like, or may be distinguished by bands of different colors or patterns.

  Further, the gap G from the upper side portion 21a of the bag body 21 to the double-sided adhesive tape 22 may be two times or more than five times the tape width W, but it is three times 4 in consideration of the certainty of sealing and the size of the bag. Double is desirable.
