Description

  The present invention relates to a packaging bag and a packaging body in which a part of an article to be packaged is taken out from a bag made of a plastic film and is deflated and bound on the upper side of the article to be packaged accommodated in the bag. About.

Conventionally, as a packaging form that brings out a high-class feeling in bread, chocolate, candy, cookies, and other various foods, the packaging bag is accommodated in the packaging bag and the opening is closed, and then the packaging bag is placed near the upper side of the packaging object. A wrapping form in which the upper portion of the bag above the bound portion is fanned out is performed (see Patent Documents 1 and 2). This packaging form is not only a packaging form that brings out a high-class feeling, but is a packaging form of an article to be packaged that requires taking out the necessary amount instead of taking out the whole amount and resealing. Therefore, the binding tool is used for resealing. There are various binding tools, for example, there are those shown in Patent Documents 3 and 4. In addition to this, there is one that winds a ribbon with wire, and further there is a binding means that winds and binds a string.

In fact, the binding devices of Patent Documents 1 to 4 cannot be easily re-fitted to the deflated portion of the bag and are difficult to assemble, so that it is very rarely used for resealing. .
The wire ribbon may be lost in the same manner as the plastic chip binding tool, and the string cannot be wound around without being tied around with one hand.
Therefore, after opening the bag package, do not use the removed tying tool, and it is desirable to provide another means of binding that can easily bind the deflated portion of the bag and that can be tied without being tied and lost. It is rare. There is a bag with a zipper as a bag with a reseal function. However, if the zipper is attached, the cost will be considerably increased and the price competitiveness will be significantly reduced, and it is difficult to attach the zipper to a soft film. Insertion for resealing cannot be performed smoothly.

  The present invention has been devised in view of the above points, and when a part of the package is taken out from the bag and needs to be resealed, it is deflated on the upper side of the package to be stored in the bag by the binding means. It is a packaging bag made of plastic film that binds, and does not use a plastic plate binding tool for binding, and it has binding means that can be tied without tying up the deflated portion of the bag, and it is not costly and can be lost It is to provide a packaging bag and a package.

As means for solving the above-mentioned problems, the packaging bag of the present invention is a packaging bag made of a plastic film that needs to be resealed, wherein the plastic film is an unstretched or weakly stretched plastic film, and has a front portion and a rear portion. At the upper end of any one of the surface portions, there is a belt-like portion that can be separated from the easy separation line provided parallel to the upper end, and at least one end is connected to the bag side edge when separated from the easy separation line. It is formed.
The packaging bag of the present invention is preferably a self-supporting packaging bag having a bottom gusset, but may be a bag of another form such as a three-sided seal bag. The easy separation line is a perforation cut or a half cut.
The package of the present invention is characterized in that an article to be packaged is accommodated in the packaging bag having the above configuration.

  According to the above configuration, when it is necessary to open the bag from the upper end of the bag and leave the packaged item in the take-out bag instead of the entire amount in the bag and re-seal it, Separate from the line and make a strip. Since the packaging bag is made of an unstretched or weakly stretched plastic film, this strip is also an unstretched or weakly stretched plastic film and has the property of being stretched and loosened when pulled, but this restoring property is the restoration of rubber. Much smaller than the nature to do. Therefore, using this band-like part, the upper part of the bag is not tied and tied at the upper side of the packaged object accommodated in the bag, but at least one end of the band-like part is not separated from the bag. When the hand is released by winding the swollen portion of the bag with this belt-like part, the inner wrapping part around which the belt-like portion is wound first receives the force to spread the wilted part of the bag. The outer wrapping part wound from the side receives the force that the deflated part of the bag receives no or little force to spread, so the degree of restoration of the inner wrapping part is large and tightly tightened with the part tightened from the outside It can be kept in a state and bound.

  According to the present invention, after opening, a binding tool is not used, only a part of the bag is cut off from the perforation, and one end or both ends of the bag are wound around the deflated portion of the bag as a band-like portion that cannot be cut off. It is possible to provide a universal design that serves as a binding tool that can be easily bundled, and has the advantage that it is not separated from the bag, so there is no risk of accidental ingestion, and there is almost no cost without loss.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a front view of the packaging bag of the present invention. The packaging bag P includes a front surface portion 11, a rear surface portion 12, and a bottom gusset 13. The packaging bag P is made of a single layer film having heat-sealability with unstretched or weakly stretched film such as a polyethylene film or a polypropylene film. This packaging bag P forms a front surface portion 11, a rear surface portion 12, and a bottom gusset 13 by placing a continuous film on a former and folding it so that the cross section perpendicular to the continuous direction is M-shaped. Then, the side seal 14 is applied by a fusing seal cutter and cut by fusing.

  In the packaging bag P, the upper end of the rear surface portion 12 extends, for example, 40 mm higher than the upper end of the front surface portion 11, and two holes 12 b are formed in a portion 12 a extending higher than the upper end of the front surface portion 11 of the rear surface portion 12. It is a winch type bag form.

  The packaging bag P is provided with an easily separating line 15 along the upper end of the front surface portion 11 to the vicinity of the third seals on both sides. This easy separation line 15 is a perforation cut. When this easy separation line 15 is traced and separated, a band-shaped portion 16 is formed at the upper end of the front surface portion 11. Since the belt-like portion 16 is connected to both side edges of the bag, there is no fear that it will be separated and lost. It is desirable that the band-like portion 16 is provided with a notch 17 at one end so that the one end side can be separated from the bag side end so as to become a long string.

  FIG. 2 shows a perspective view of a package body in which the bread B is packaged with the packaging bag P. Since this packaging bag P has the bottom gusset 13 as shown in FIG. In this packaging bag P, the upper part of the front face part 11 and the upper part of the rear face part 12 are opened and the bread B is accommodated, and the upper part of the front face part 11 and the upper part of the rear face part 12 are closed together, and the adhesive strength is weak. Sealed by a seal. This heat sealing is preferably performed while avoiding the belt-like portion 16. After this heat sealing, the upper part of the bag is deflated on the upper side of the bread B and bound with the binding tool K, and the upper part of the bag is fanned out from the binding part. As the binding tool K, for example, binding tools as shown in Patent Documents 2 to 5 can be used.

  In the case of bread wrapping, the form in which the upper part of the bag is deflated and bound with the binding tool K is widely established, and the top seal (weak heat seal) of the packaging bag P is removed and the desired number of sheets is removed. When the bread B is taken out and the whole bread B is not eaten, the remaining bread B is left in the packaging bag P and resealed with the binding tool K. However, once the binding tool K is removed, it is troublesome to deflate the top of the bag again and reattach the binding tool K, and the binding tool K is not actually reused much. The packaging bag P of the present invention may not use the binding tool K that is troublesome to reseal.

FIG. 3 shows a perspective view of the package in a resealed state. The bundling tool K shown in FIG. 2 is not used for this reseal. Instead of the binding tool K, the band-like portion 16 is used.
That is, the binding tool K is removed, and the top seal at the upper end of the packaging bag P is peeled off to be opened. When taking out not only the entire amount of bread B but a desired amount and resealing it from the bag, do not use the binding tool K shown in FIG. 2, and cut the strip 16 from the easy separation line 15 provided on the packaging bag P. Using this band-like portion 16, the deflated portion of the packaging bag P is wound around and bound. Since the strip 16 is made of an unstretched or weakly stretched plastic film, it has a property of restoring when pulled and loosened, but this restoring property is much smaller than the restoring property of rubber. Is connected to the side edge of the bag. For this reason, using this strip | belt-shaped part 16, even if it does not hold down with the finger | toe especially as one end connected to the bag side edge with a finger | toe, it is made to wind around the deflated part of the packaging bag P. Even if you release your hand without tying up against the deflated part of the packaging bag P, the degree to which the inner wrapping part is to be restored is large, and it will be in tight contact with the part tightened from the outside It can be maintained and united.

The present invention is not limited to the above-described embodiments and examples, and includes various design changes that do not depart from the gist.
(1) Although the packaging bag of the said embodiment has a bottom gusset and becomes a packaging form which becomes a preferable square bottom when applied to bread, for example, it is high-grade in chocolate, a candy, a cookie, sugar confectionery etc. It can be applied to packaging forms that create a feeling. It is also applied to packaging of toys other than food, for example.
(2) Although the packaging bag of the said embodiment has a bottom gusset, the bag of other forms, such as a three-side seal bag and a pillow packaging bag, is also included. In order to provide the pillow packaging bag with the belt-like portion 16 that can be separated from the easy separation line 15, a non-sealed portion between the bottom seal of one bag and the top seal of the other bag adjacent to the one bag. The non-sealed portion is positioned closer to the top seal by making the width dimension larger than usual and cutting the non-sealed portion by the bottom seal. The top seal is a weak heat seal. When the non-seal part is close to the top seal, a perforation is provided to form a belt-like part that can be separated from the side edge of the bag. To prevent the perforation from being cut off from the side edge of the bag, a small-diameter round hole should be removed.
(3) Although the packaging bag of the said embodiment showed the winket type bag, the bag with which the upper end of the front part and the upper end of the rear surface part corresponded may be sufficient.
(4) In the above embodiment, the packaging body shown in FIG. 2 is deflated at the upper side of the packaged article accommodated in the bag and bound by the binding tool K, and the upper part of the bag is expanded in a fan shape from the binding part. Although it is in a packaging form, at the stage of an unopened packaging form, the upper part of the bag is not deflated at the upper side of the article to be packaged contained in the bag and is not bound by a binding tool at all. At the stage of taking out the desired amount instead of the total amount and resealing it, the strip 16 is cut off from the easy separation line 15 provided in the packaging bag P, and the packaging bag P is deflated using this strip 16. Including winding the parts around and binding them. This package is environmentally friendly because it is resealed with the same material without using the binding tool K.
(5) The belt-like portion preferably has a structure in which one end is connected to the bag side edge when cut off from the easy separation line 15, but may be a structure in which both ends are connected to the bag side edge.
(6) As in the above embodiment, either one of the front surface portion and the rear surface portion is stretched high, the upper upper end inner surface is overlapped with the lower upper end outer surface, and the overlapping surface is adhered with an adhesive to open the bag opening. It also applies to packaging bags that close
(7) The packaging bag P includes a non-stretched or weakly stretched multilayer film having heat-sealing properties, such as co-extrusion polyethylene film or polypropylene film.
