DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings. The following example is applied to a mail envelope as an example.
[Example 1]
A multi-use envelope according to a first embodiment of the present invention is shown in FIGS.
As shown in FIGS. 1 and 2, the multipurpose envelope of the present embodiment is provided with a sealing flap portion 20 at the upper front end of the bag body 10, and further provided with a sealing extension flap portion 30 on the sealing flap portion 20. Is.
In the first use, as shown in FIG. 2, the sealing extension flap 30 is folded inside the sealing flap 20 and the sealing flap 20 is folded. As shown in FIG. The flap part 30 is stuck on the bag body 10 and sealed.
That is, the sealing flap portion 20 and the sealing extension flap portion 30 are folded in a double state.
[0009]
At this stage, as shown in FIG. 4, the sealing extension flap portion 30 is glued and the sealing flap portion 20 is not glued, so that a cavity 50 is formed between the sealing flap portion 20 and the bag body 10. In the drawing, the cavity 50 is exaggerated.
When opening, a paper knife or the like is inserted into the cavity 50 between the sealing flap part 20 and the bag body 10 and pulled down, so that the sealing extension flap part 30 and the sealing flap part 20 are Separate.
Then, at the time of the 2nd use, it seals by sticking the flap part 20 for sealing to the bag main body 10 as usual.
[0010]
As described above, when the first use is performed, sealing is performed by the sealing extension flap portion 30, and when the second use is performed, the sealing flap portion 20 can be sealed, and reuse as an envelope becomes possible.
However, if the sealing flap part 20 is separated from the bag body 10 and opened after the first use, the second use cannot be used as an envelope.
For this reason, in the first sealed state, the bag body 10 has a cautionary note 40 that “it can be easily opened by inserting a paper knife or the like from the side of the top cover of the envelope” so that it can be seen below the sealing flap 20. It is good to display in.
In order to clarify the opening location, it is also effective to put a mark or display a broken line with a mark at the lower portion of the sealing extension flap 30.
[0011]
Further, in order to facilitate the opening, a perforation for opening or an opening string can be provided between the sealing flap part 20 and the sealing extension flap part 30.
Further, since the surface of the sealing extension flap portion 30 shown in FIG. 1A is a glue surface, glue may be attached in advance, or a double-sided tape may be attached.
Similarly, since the back surface of the sealing flap 20 shown in FIG. 1B is a glue surface, glue may be attached in advance, or a double-sided tape may be attached.
[0012]
Another example of use of the multipurpose envelope of this embodiment is shown in FIG.
This example is applied when a strict document is sent, and the sealing flap part 20 and the sealing extension flap part 30 are glued to the back surface of the bag body 10 at the same time.
In this way, the envelope is limited to one-time use and cannot be reused. However, since the sizing area is doubled compared to a general envelope, the possibility that the sizing part is peeled off during mailing is reduced.
In addition, since reuse as an envelope is not performed in this way, when opening, it is performed by separating the sealing flap portion 20 from the bag body 10.
[0013]
[Example 2]
A multi-use envelope according to a second embodiment of the present invention is shown in FIGS.
As shown in FIG. 6, the multi-purpose envelope according to the present embodiment further includes a sealing extension flap portion 20 in the sealing flap portion 20 in the envelope in which the sealing flap portion 20 is provided at the upper front end of the bag body 10. In addition, a sub-flap portion 60 is provided at the upper end of the back surface of the bag body 10.

In this embodiment, since the sealing flap 20 and the sub-flap 60 are overlapped to form two sheets, it is difficult to separate the sealing flap 20 from the bag body 10 with a paper knife or the like. The flap part 30 and the sealing flap part 20 are urged to be separated and opened.
Therefore, according to the present embodiment, there is an advantage that it can be reused as an envelope more reliably.
[0015]
Moreover, at the time of the 2nd use, as usual, the flap part 20 for sealing is stuck on the bag main body 10 and the sub flap part 60, and is sealed.
Furthermore, when sending a strict document, etc., the same function as the envelope for cash registered mail is exhibited by gluing the extension flap part 30 for sealing, the flap part 20 for sealing, and the sub-flap part 60 folded together. It is also possible to make it.
In this way, the envelope is limited to one-time use and cannot be reused. However, since it is glued in triplicate compared to a general envelope, there is less possibility that the glued part will be peeled off during mailing.
[0016]
In addition, since reuse as an envelope is not performed in this way, when opening, it is performed by separating the sealing flap portion 20 from the bag body 10.
Also in the present embodiment, as in the above-described embodiment, in order to facilitate opening, a perforation for opening or an opening string is provided between the sealing flap portion 20 and the sealing extension flap portion 30. You can also.

[0021]
[Comparative Example]
As a comparative example of the present invention, firstly, Japanese Patent Application No. 10-94360 (Application A) is mentioned.
The former application is a double flap mail envelope described in the following claims 1 and 2, and each claim has respective requirements.
[0022]
[Claim 1]
(A) The flap has a double structure, and the first part is used as the first address field and the peelable sealing field, so that the first mail can be sent.
(B) Next, the recipient peels off the first flap and separates it with a perforation made in advance,
(C) If the contents are taken out, the remaining envelope can be used again as a mail envelope if sealed by the second flap.
[0023]
[Claim 2]
(D) A cut perforation is made on the first flap so that the two parts 1-1 and 1-2 can be separated;
(E) Applying weak adhesive to the back of the first flap and the corresponding part of the bag, enclosing the contents, then weakly pressing the weak adhesive together, and simultaneously sealing the second flap and mailing The delivery person stamps the recipient's signature or seal on the 1-1 part, which is cut off from the perforation and used as a registered mail receipt.
[0024]
According to the description of the detailed description of the invention of the specification of this application, the application is intended to obtain a double-flap mail envelope that can be used twice round-trip and is useful for saving resources and reducing waste. Therefore, it is clear that the flap has a double structure, and the above-mentioned object is achieved by separating the first flap portion and the second flap portion.
[0025]
In addition, when the description of the embodiment in the detailed description of the invention (the above publication, page 2, right column, line 1 to line 35), in Examples 1 and 2, the flaps are 1-1 and 1-2. A weak adhesive layer 4-1 is applied to the long side of the flap 1-1, and a second sealing adhesive (for example, rewet) 5 is also applied to the flap 1-2. The envelope recipient peels off the flap 1-1, cuts out the flap 1-1 with the sewing machine 2, takes out the contents, and then uses this for further reply to the remaining flap 1-2. It is described that sealing may be performed with the applied adhesive 5.
[0026]
In addition, when the description of the embodiment in the detailed description of the invention (see the above publication, page 2, right column, line 36 to page 3, left column, line 1), in Example 3, a double flap was used. A registered mail envelope is described, and after the contents are put, not only the flap 1-1 is pressure-bonded to the weak adhesive layers 4-1 and 4-2, but also the flap 1-2 is re-wetted by the rewet adhesive 5. And thus, if the recipient's seal is imprinted or signed on the flap 1-2, the flap 1-2 can be cut out and used as a delivery certificate for registered mail.
[0027]
According to the description of the specification of such an application A, the invention according to claims 1 and 2 includes the following aspects.
One aspect thereof relates to the first aspect, wherein the first flap 1-1 and the second flap 1-2 can be separated by the perforation 2, and the first flap 1- is used at the first use. It is understood that the first flap 1-1 is cut by the perforation 2 and opened and then sealed with the second flap 1-2.
Another aspect relates to claim 2, wherein the first flap 1-1 and the second flap 1-2 are separable at the perforation 2, and are sealed by the first flaps 1-1 and 1-2. The first flap 1-1 is cut by the perforation 2 to be a receipt of registered mail.
[0028]
In addition, the specification of the first application does not describe an aspect in which the first flap 1-1 and the second flap 1-2 are folded twice, and the adhesive layers 4-1 and 4-2 are also described. They are on the same plane.
In particular, the specification of the application A only describes that the perforation 2 is used for cutting, and no consideration is given to opening using a paper knife or the like.
Therefore, “double flap” in the former application does not mean that the flap is folded twice as seen in the above two aspects, and the two flaps can be cut through the perforation. It must be understood that it has only been extended.
[0029]
As described above, when the inventions according to claims 1 and 2 of the application A are compared with the invention of the present application, the following conclusions are obtained.
First, the requirement (a) of claim 1 relating to the first application is common in that there are a plurality of flaps, but in the first application, the first flap is not folded with respect to the second flap. On the other hand, the present invention is different in that the sealing extension flap part is double-folded with respect to the sealing flap part at the first use.
Next, with regard to requirement (b) of claim 1 relating to the first application, the first application requires a perforation as an essential constituent requirement, whereas in the present invention, it is not always necessary in consideration of separation with a paper knife or the like. It is different in that it does not.
[0030]
Further, the requirement (c) of claim 1 relating to the former application is common in that it is used as a normal envelope at the second use.
Further, with respect to requirement (d) of claim 2 relating to the former application, while the former application makes the perforation an indispensable constituent requirement, it is not always necessary in the present invention in consideration of separation with a paper knife or the like. It is different in that it is not.
In addition, regarding the requirement (e) of claim 2 relating to the first application, the first application seals the first and second flaps at the same time, whereas in the present invention, for the purpose of reuse, two flap portions are used. Are different in that they have different gluing surfaces and are not glued at the same time.
[0031]
As described above, although the invention according to the former application and the present invention are common in the configuration requirement (c), the configuration requirements (a), (b), (d), and (e) are different from each other. However, the present invention does not belong to the technical scope described in the claims of application A.
Furthermore, the present invention has an advantage that it is wider and easier to use for general people than the former application in that the gap portion is formed by folding the flap portion twice in order to facilitate opening with a paper knife or the like. .
[0032]
On the other hand, as another comparative example, Japanese Patent Application No. Hei 5-9764 (hereinafter referred to as “Application B”) can be cited.
As in the case of the former application, this second application describes that two parallel glues are provided on the envelope sealing part, and a scissor cut is provided in the middle of the parallel glue. It can be used to save money and save paper.
However, unlike the present invention, this second application does not take into account the double folding of the sealing part or the opening using a paper knife or the like.
[0033]
Furthermore, as another comparative example, Japanese Utility Model Application No. 10-6979 (hereinafter referred to as “Tsubaki Application”) can be cited.
In this bag application, as in the case of the above-mentioned application A, a display tongue portion further extended through a cut perforation is integrally formed on the end portion of the folded sealing tongue provided in the document loading / unloading opening portion. It describes that an envelope can be used twice.
However, unlike the present invention, this second application does not take into account the double folding of the sealing portion or the opening using a paper knife or the like.
[0034]
Furthermore, as another comparative example, there is Japanese Patent Application No. 63-34878 (hereinafter referred to as the “Ding application”).
In this Ding application, a section piece is provided at the center, and the envelope is made of a synthetic resin as a whole. However, the multipurpose envelope according to the present invention is not provided with a section piece, There is no reason to use resin.
Further, this application does not describe how to fold the sealing portion and does not consider reuse as an envelope.
[0035]
Even if the description related to the second, second, and second applications is combined with the description of the first application, there is no suggestion about a multi-purpose envelope similar to the present invention, and the multi-purpose envelope of the present invention is a paper. There is a significant advantage not described in the former application that it is easy to open using a knife or the like.
[0036]
【The invention's effect】
As specifically described above based on the embodiments, the present invention has the following effects.
(1) To fold the sealing extension flap inside the sealing flap and to fold the sealing flap, that is, to fold the flap twice, a cavity is formed between the bag body and Easy to open by inserting a paper knife into the cavity.
(2) Even after the sealing extension flap and the sealing flap are separated and opened, they can be reused if they are glued to the bag body with the sealing flap.
(3) If a sub-flap part is provided at the upper end of the back of the bag body, the sub-flap part and the sealing flap part overlap each other, resulting in a double stack. Can be opened by the extension flap.
(4) When the side flap portion is provided, the cavity formed between the flap portion and the bag body is covered with the side flap portion, so that foreign matter is not easily infiltrated from the outside, and fine contents do not jump out.
