By the way, according to the hanging bag disclosed in Patent Document 1 and Patent Document 2, when the bag is lowered using the hanging string, the opening of the bag body remains closed, but the bag body does not close. When the bag is placed on a desk or the like, the upper opening of the bag naturally opens because the traction effect of the hanging string is eliminated. For this reason, there is a problem that the packaged item is exposed through the opening and the appearance is spoiled.

Therefore, this invention was made to solve the above-mentioned problems, and it is easy to handle, does not increase costs, and prevents the opening from opening inadvertently and exposing the packaged item. It is an object of the present invention to provide a packaging bag that can be used for packaging purposes and has an excellent appearance and appearance.

Each end of the sealing body is inserted into the first and second communication holes in a state where the sealing body is positioned at the front, thereby attaching the sealing body to the bag body and closing the opening. do.

In this case, in a preferred embodiment, a message card integrated with or separate from the seal is provided in the longitudinal center of the seal, and the message card is attached to the front bag piece of the bag. A front-facing configuration is adopted.

Furthermore, it is preferable to adopt a configuration in which an adhesive is applied to a surface of each end of the sealing body that faces the bag body, so that the sealing body can be stuck to the bag body. can.

According to the above-mentioned packaging bag according to this invention, each end of the rectangular sealing body is inserted into at least the first and second communication holes formed in communication with the front and rear bag pieces, respectively. By inserting the bag pieces from the front side toward the rear side, the front and rear bag pieces are brought into close contact with each other as the sealing body is restored to its flat state. Thereby, the opening of the bag is sealed with one strip-shaped sealing body.
Therefore, by using a somewhat thick and highly rigid paper base material as the sealing body, and by combining it with a paper bag body, we have realized packaging that is plastic-free and has an excellent appearance and appearance without increasing costs. We can provide bags for your use.

In addition, a message card is provided in the longitudinal center of the sealing body, and by attaching a message to celebrate birthdays, entering kindergarten, school entrance, etc. to this card, this message card can be placed at the top of the front of the bag. Become. Therefore, it can contribute to further increasing the value of the bag for packaging gifts and the like.
Furthermore, by applying an adhesive to the surface facing the bag at each end of the seal, the seal can be reliably fixed at a predetermined position on the bag. This makes it possible to provide a packaging bag in which the opening of the bag can be reliably sealed.

The bag body 1 includes a sealing body 2 formed in a rectangular shape for sealing the opening of the bag body 1.

In this bag body 1, front and rear facing bag pieces 1a and 1b are connected at the bottom by a rectangular bottom body 1c, and the front and rear bag pieces 1a and 1b have a side body 1d that can be folded inward. The left and right sides are respectively connected via the cables to form a self-supporting state.
As a result, a rectangular opening 1e for loading and unloading the product is formed in the upper part.
Then, each end of the hanging string 1f is attached to the vicinity of the opening 1e of each of the bag pieces 1a, 1b that face each other in the front and back, corresponding to each bag piece 1a, 1b, so that the hanging string 1f forms a handbag, and thereby the bag body 1 constitutes a handbag.

In addition, the front and rear bag pieces 1a and 1b constituting the bag body 1 are connected to two places on the left and right along the opening 1e when the opening 1e is closed. First communication holes 1a1, 1b1 and second communication holes 1a2, 1b2 are formed, respectively.
The communication holes 1a1, 1b1 and 1a2, 1b2, which overlap in the front and rear, are each formed in the shape of a vertically long slit, and the entire bag 1 is made of paper material.

On the other hand, the sealing body 2 that seals the opening 1e of the bag body 1 is formed into a strip shape having approximately the same dimension width along the longitudinal direction, and this sealing body 2 is made of slightly thick and highly hard paper. A base material is used.
In the illustrated example, an adhesive 2a is applied to one side of both ends of the sealing body 2, and a release paper 2b is attached to cover the adhesive 2a.

2 and 3 show a state in which the opening 1e of the bag 1 is sealed by attaching the sealing body 2 formed into a rectangular shape to the above-mentioned communication holes 1a1, 1b1 and 1a2, 1b2 that overlap in the front and back. It shows.
That is, in order to attach the sealing body 2 to the bag body 1, one (left side) end of the sealing body 2 is attached with the longitudinal center part of the sealing body 2 positioned in front of the front bag piece 1a. are passed through the overlapping first communication holes 1a1 and 1b1, and the other (right side) end of the sealing body 2 is passed through the overlapping second communication holes 1a2 and 1b2.

By placing each end of the sealing body 2 along the back side of the rear bag piece 1b, the sealing body 2 is restored to its flat state, and the opening between the front and rear bag pieces 1a and 1b is The area near 1e is in close contact. Thereby, the opening 1e of the bag 1 can be sealed with a single strip-shaped sealing body 2.
In addition, in FIG. 2, an example is shown in which the sealing body 2 is attached in a meandering state to each of the front and rear bag pieces 1a and 1b shown in a straight line, but as described above, the sealing body 2 is Since the paper base material is slightly thicker and more rigid than each bag piece 1a, 1b, in reality, each bag piece 1a, 1b has a meandering shape with respect to the substantially straight sealing body 2. It will be installed in the same condition.

Further, in the illustrated example, each end of the sealing body 2 is coated with an adhesive 2a facing toward the back side of the rear bag piece 1b. Therefore, after attaching the sealing body 2 to the bag body 1, by peeling off the release paper 2b covering the adhesive 2a and pressing each end of the sealing body 2 toward the back side of the rear bag piece 1b, By using the adhesive 2a applied to each end of the sealing body 2, the sealing body 2 can be reliably attached to the bag body 1.
Note that the rectangular sealing body 2 can be attached to the opening 1e of the bag body 1 without using the adhesive 2a, so when implementing the packaging bag according to this invention, the adhesive Agent 2a is not necessarily required. Therefore, it can be selected as appropriate whether or not to use the sealing body 2 coated with the adhesive 2a.

FIG. 4 shows an example in which a message card 2c is integrally molded in the longitudinal center of a strip-shaped sealing body 2. In FIG. 4, parts corresponding to each part shown in FIG. 3 are shown. They are indicated by the same reference numerals, and their explanation will be omitted.
