In recent years, the envelope material is made of a synthetic resin film, and an envelope in which the entire enclosed material or a part of the address information written on the surface of the enclosed material can be visually observed from outside. Many are in circulation. As the form of the envelope, there is a conventional structure in which the outlet on one side is covered with a sealing piece. That is, as in the case of a paper envelope material, two sheets are opposed to each other to form an envelope body with one side serving as a take-out port, and one sheet is provided with a folding section at the take-out port side to close the sheet. The pieces are connected to each other, and the folded sealing piece and the side portion of the other sheet, which faces the sheet, on the take-out port side, which are opposed to each other, are attached to each other via an attaching means.

However, in the above-mentioned wrapping type envelope using a sheet made of a synthetic resin film, one perforation is processed along the sealing portion for opening, but when tearing that portion and opening it, There is a problem that the synthetic resin film, which is the material, stretches and the crevice becomes dirty. On the other hand, in the conventional structure of the envelope in which the envelope material is a sheet made of a synthetic resin film and the sealing piece is provided, the shape of the take-out port for taking in and taking out the enclosed matter does not collapse during opening. However, since the sealing piece is adhered to the other sheet side by the adhering means using an adhesive over the entire width direction, when the sealing piece is rolled up, the adhering means near the take-out port. The adhesive is exposed, and when you take out the enclosure or insert it in the envelope body, it is easy for the enclosure to stick to the adhesive located on the sealing piece side, so be careful when taking out and putting in the enclosure after opening. There is a problem of cost.
Therefore, the present invention uses a synthetic resin film or the like as an envelope material, and in an envelope provided with a closure piece in a one-sided opening type, to prevent the pressure-sensitive adhesive on the closure piece side from being exposed even when the opening is performed at the outlet portion. It is an object of the present invention to eliminate the trouble of putting in and taking out an enclosed matter in an opened envelope and to make it possible to easily take in and out the enclosed matter.

BEST MODE FOR CARRYING OUT THE INVENTION Next, the present invention will be described in detail based on the embodiments shown in FIGS. In the figure, reference numeral 1 denotes an envelope, and the envelope 1 is made of a transparent synthetic resin film as an envelope material. Two envelope walls are formed by folding a continuous synthetic resin film, one side being the front side of the envelope and the other side being the back side of the envelope. 2 and 3 are opposed to each other (see FIG. 1B), and the opposing sides are sealed by heat sealing or the like to form the envelope body 5 having one side as the outlet 4. Then, the sealing piece 7 is connected to the side of the one of the envelope walls 2 on the side of the outlet 4 via the folding portion 6, and the sealing piece 7 is folded from the folding portion 6 and the outlet 4 of the other envelope wall 3 facing the other. The side portion 8 on the side is pasted through the pasting means 9, and the take-out port 4 is sealed while the enclosure A is arranged.

In the envelope 1 having the above structure, the folded portion 6 between the envelope wall 2 and the sealing piece 7 is subjected to strength deterioration treatment such as scoring, perforation, heat deterioration and the like, so that it can be easily torn. It is provided in. Since the folding part 6 can be easily torn in this way, if a trigger for tearing is added from the end of the folding part 6 as will be described later, the tear will easily advance along the folding part 6. .

The outlet 4 of the one envelope wall 2 is also provided.
On the inner surface on the side, along the folding part 6, a strip-shaped reinforcing member 1
0 is attached. The reinforcing member 10 is made of a flexible and rigid film sheet or the like, and the side portion 11 of the reinforcing member 10 on the side of the folded portion 6 is aligned with the folded portion 6 to take out the envelope wall 2. It is attached to the inner surface on the 4 side by an attaching means 12 such as an adhesive, and can be rolled up from the free end side. In this way, the folding part 6
Since the reinforcing member 10 is attached along the side of the envelope wall 2, the rigidity of the portion on the side of the folded portion 6 of the envelope wall 2 has the rigidity of the folded portion 6 of the sealing piece 7.
The rigidity is higher than that of the side part. Therefore, if the end portion of the sealing piece 7 is pulled in the width direction (length direction) of the sealing piece and peeled off, the reinforcing member 10 serves as a guide and cuts while appropriately concentrating stress on the folding portion 6. Will be able to. Further, as described above, since the folded portion 6 itself is provided so as to be easily torn, even when the end portion of the sealing piece 7 is rolled up, tearing at the folded portion 6 is likely to occur, and the entire folded portion 6 is Due to the fact that it is provided so that it can be easily torn and the presence of the above-mentioned reinforcing member 10, the crevice can proceed more properly, and the sealing piece 7 can be easily separated from the envelope wall 2 (see FIG. 3). ). Although the reinforcing member 10 is attached by the double-sided adhesive tape or the like in the above-mentioned embodiment, the attaching means 12 is not limited to this, and a heat seal, a hot melt adhesive or the like may be used. Good.

The sticking means 9 for sticking the sealing piece 7 to the side portion 8 of the envelope wall 3 on the side of the take-out port 4 is located over the entire length in the width direction of the sealing piece 7 as shown in the drawing. The sticking means 9 is not provided between the both end sides of the sealing piece 7 which are orthogonal to the folded part 6 and the facing areas of the both sides of the side part 8 which the sealing piece 7 faces. Opposite via 13. Since the facing areas of the sealing piece 7 and the end of the side portion 8 are not bonded to each other in this manner, it is easy to perform finger hooking when rolling up the sealing piece 7 in its width direction. The end of the sealing piece 7 can be easily grasped and held. Therefore, the operation of peeling off the sealing piece 7 while pulling it from the end portion in the width direction thereof can be easily performed (see FIG. 2).

FIG. 4 shows the state after opening, in which the free end side of the reinforcing member 10 is rolled up, and then the side portion 8 of the envelope wall 3 on the side of the outlet 4 is covered, whereby the outlet 4 is removed. Is bound so that it can be opened and closed. In this way, the reinforcing member 1
Since the take-out port 4 can be closed at 0, it becomes possible to hold the enclosure in the envelope body even after opening the envelope, and the envelope after opening can be reused as a container. In the above embodiment, in which the sealing piece can be properly separated from the folded portion, the folded portion is weakened to facilitate the separation, and the reinforcing member is provided. However, both means are not necessarily required to be used together.

[0010]

According to the present invention described above, since the sealing piece is peeled off at the time of opening, there is no sticking means near the take-out port after opening, so that the inclusion can be easily taken in and out. Further, the sealing piece can be easily peeled off, and the shape of the opening edge does not collapse due to the crevice properly advancing along the folding portion, and the shape after opening is also adjusted. Further, if the reinforcing member is provided along the folding portion, the sealing piece can be more properly peeled off. Then, if the outlet is covered with the reinforcing member,
The opened envelope can be reused as a container for inclusions,
It is highly economical and practically effective.
