Then, when checking the contents at the store, the delivery bag is cut and opened with scissors or the like (step S13), and the bag is discarded. Next, after the contents are confirmed (step S14) and procedures such as purchase are performed (step S15), the clerk wraps the product in a new packaging bag (step S16), and the purchaser The newly wrapped product is brought back (step S17). For this reason, at the time of receiving a store for buying and selling goods via the Internet, when a purchaser checks the contents, at least two bags, a delivery bag and a packaging bag, are consumed.

  The present invention has been made in view of such circumstances, and in a case where a bag in which an article is stored is opened and then resealed, the amount of garbage to be discarded is reduced, which has an adverse effect on the environment. It is an object of the present invention to provide a synthetic resin bag which can reduce the number of pieces and which can be quickly and easily opened without damaging the article, and a method for using the same.

In order to solve the above problems, the synthetic resin bag of the present invention and the method of using the same employ the following means.
That is, the synthetic resin bag according to the present invention has an opening formed at one end side in the length direction, and a storage portion capable of storing articles inside through the opening, A flap extending from the storage portion and extending in a width direction perpendicular to the length direction, and a handle connected to the storage portion on a side opposite to the opening portion, wherein the flap includes the flap, An opening portion in which two perforations are formed along the width direction; a first sealing portion provided along the opening portion on the tip side of the flap than the opening portion; A second sealing portion provided along the opening portion on the opening side, and the opening portion penetrates between the two perforations at a widthwise intermediate portion of the flap. A part is formed.

  According to this configuration, in the flap, the opening portion, the first sealing portion, and the second sealing portion are formed along the width direction of the storage portion. The first sealing portion is provided closer to the tip of the flap than the unsealing portion, and is used when the opening is sealed for the first time. Further, since two parallel perforations are formed on the flap by the opening portion, the space between the two parallel perforations can be removed. The storage section sealed by the first sealing section is opened by removing a space between two parallel perforations. The second sealing portion is provided closer to the opening than the opening portion, and is used when the opening is sealed again after the opening is opened by the opening portion.

  Furthermore, since the penetrating portion is formed at the center in the width direction of the opening portion, the opening portion can be easily removed starting from the penetrating portion. Further, since the handle portion is provided at the end of the storage section, it is easy to carry the stored articles.

In the above invention, the length of the penetrating portion in the length direction may be equal to or larger than the interval between the two perforations.
According to this configuration, since the penetrating portion is provided on the two perforations, it is easy to open when opening with the penetrating portion as a starting point.

In the above invention, the through portion may be a through hole formed to open in the width direction.
According to this configuration, since the through-hole that opens in the width direction is formed, it becomes easy to catch a finger or the like at the time of opening, and it becomes easy to open.

  In the above invention, in the perforation, a plurality of cut portions penetrating the flap are arranged at intervals from each other, and the cut portion is separated from the width direction end portion of the flap or the through hole. It may be formed at a different position.

  According to this configuration, the perforations are formed by arranging the plurality of cut portions penetrating through the flap at an interval from each other, and the cut portions of the perforations are formed in the width direction ends of the flaps or through holes. It is formed at a position apart from. Therefore, compared to the case where the cut portion is formed at the end in the width direction of the flap or at the position in contact with the through hole, the opening portion is less likely to be removed starting from the cut portion with a simple force.

  In the above invention, in the perforation, a plurality of cut portions penetrating the flap are arranged at intervals from each other, and the plurality of cut portions are in the vicinity of the width direction end of the flap, or In the area near the through hole, the interval may be wider than in other areas.

  According to this configuration, the perforations are formed by arranging the plurality of cut portions penetrating through the flap at an interval from each other, and the plurality of cut portions of the perforation are formed in the vicinity of the width direction end of the flap. Alternatively, in the region near the through hole, the interval is wider than in other regions. Therefore, in the region near the widthwise end of the flap or in the region near the through hole, the unsealing portion is less likely to be removed than in the region where the interval between the plurality of cut portions is narrower.

  The method of using a synthetic resin bag according to the present invention is the method of using a synthetic resin bag described above, wherein the step of sealing the opening using only the first sealing portion includes the steps of: Removing the opening between the two perforations of the unsealing portion as a starting point to open the opening sealed by the first sealing portion; and, after the unsealing portion is removed, Sealing the opening using two sealing portions.

Hereinafter, a delivery and packaging bag 1 according to an embodiment of the present invention will be described with reference to the drawings.
The delivery and packaging bag 1 according to the present embodiment is an example of a synthetic resin bag, and includes a storage section 2, a flap 3, and a handle section 4, as shown in FIGS. The delivery and packaging bag 1 is made of, for example, a single-layer sheet or a multi-layer sheet made of polyethylene (for example, LDPE). The delivery and packaging bag 1 can be formed in various sizes and shapes and, unlike an envelope, can accommodate a relatively large and heavy object.

  The storage section 2 is, for example, rectangular, and has an opening 5 formed only on one side, and three sides are closed. The storage section 2 can store therein an article 20 such as a product inside. The article 20 is put in and taken out of the storage section 2 through the opening 5 in the longitudinal direction.

  An opening 5 is formed at one longitudinal end of the housing 2, and a handle 4 is formed at the other longitudinal end of the housing 2.

  The flap 3 extends from the storage section 2 on the opening 5 side, and is long in the width direction perpendicular to the length direction of the storage section 2. The opening 5 is sealed by folding the flap 3 and bonding the folded flap 3 to the outside of the storage section 2.

  The handle part 4 is connected to the storage part 2 on the side opposite to the opening part 5 with respect to the storage part 2, and is long in the width direction perpendicular to the length direction of the storage part 2. The handle portion 4 has a long through hole 6 formed in the width direction at the center in the width direction. By passing the hand through the through-hole 6, the delivery and packaging bag 1 can be carried hanging from the hand. In addition, this embodiment is not limited to the case where the through-hole 6 is formed in the handle part 4, for example, three cuts are formed in at least three directions (two in the length direction and one in the width direction). This may allow the hand to pass through.

  In the delivery and packaging bag 1, the storage section 2, the flap 3 and the handle section 4 are integrally formed. For example, a sheet made of polyethylene is folded with a portion serving as an end of the handle portion 4 as a folding line. The delivery / packing bag 1 is cut and welded while being cut to form both ends in the width direction. Are welded to each other. Thereby, the two sides facing each other are closed. The front sheet and the back sheet are thermally welded between the storage section 2 and the flap 3 in a straight line in the width direction. Thereby, one side facing the opening 5 is closed.

  In the flap 3, an opening portion 7, a first sealing portion 8, and a second sealing portion 9 are formed along the width direction of the storage portion 2, for example, parallel to the width direction of the storage portion 2. ing.

  The opening portion 7 has two parallel perforations 10 and a through hole 11 formed between the two perforations 10. In the perforation 10, for example, a plurality of cut portions 16 penetrating the flap 3 are arranged at intervals from each other. Since the two parallel perforations 10 are formed in the flap 3, the space between the two parallel perforations 10 can be removed. The storage section 2 sealed by the first sealing section 8 is opened by removing a space between two parallel perforations 10.

  The through-hole 11 is an example of a through-hole, and is formed at the middle portion in the width direction of the flap 3, and the space between the two perforations 10 of the opening 7 can be removed from the through-hole 11 as a starting point.

The first sealing portion 8 and the second sealing portion 9 have glues 12 and 14 and release papers 13 and 15 (see FIGS. 6 and 10), respectively. Glue the outside of 2 The release paper 13 is a paper for protecting the glue 12 and is peeled off when bonding with the glue 12 is performed.
The first sealing portion 8 is provided on the tip side of the flap 3 with respect to the opening portion 7. The first sealing portion 8 is used when the opening 5 is sealed for the first time.
The second sealing portion 9 is provided closer to the opening 5 than the unsealing portion 7. The second sealing portion 9 is used when the opening 5 is opened by the opening portion 7 and then the opening 5 is sealed again.

  The length of the through hole 11 in the length direction is, for example, equal to or larger than the interval between two perforations 10. Thereby, since the through-hole 11 is provided on the two perforations 10, it becomes easy to open when opening the through-hole 11 as a starting point.

  The through hole 11 is formed to have a predetermined length in the width direction and to be opened. This makes it easier for a finger or the like to be hooked at the time of opening, and it becomes easier to open. In addition, the penetrating part according to the present invention is not limited to the above-described through hole 11. The penetrating part may not have, for example, a hole shape, and may have only one or a plurality of cuts parallel to the length direction of the delivery and packaging bag 1. Further, the length in the length direction of the penetrating portion may be shorter than the interval between the two perforations 10.

  The cut portion 16 of the perforation 10 may be formed at the widthwise end of the flap 3 or at a position separated from the through hole 11. Thereby, compared with the case where the cut portion 16 is formed at the end in the width direction of the flap 3 or at the position in contact with the through hole 11, the opening portion 7 is opened with the cut portion 16 as a starting point with a simple force. It is difficult to remove. Therefore, at the time of delivery or the like, the storage portion is not easily opened.

  The plurality of cut portions 16 of the perforation 10 may be arranged with a larger interval in a region near the end in the width direction of the flap 3 or in a region near the through hole 11 than other regions. As a result, in the region near the widthwise end of the flap 3 or in the region near the through hole 11, the unsealing portion 7 is less likely to be removed than in the region where the interval between the plurality of cut portions 16 is narrower. . Therefore, at the time of delivery or the like, the storage portion is not easily opened.

Next, a method of using the delivery and packaging bag 1 according to the present embodiment will be described with reference to FIGS.
The delivery and packaging bag 1 is used, for example, in the purchase and sale of goods via the Internet, when the sales company wraps and ships the goods for each order, and the purchaser receives the goods at the physical store.
