Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an envelope.

[0002]

2. Description of the Related Art A conventional envelope is sealed by bonding a lid to the envelope body 1 using glue or a double-sided adhesive tape.

[0003] As described above, when sealing with glue or double-sided adhesive tape, there is a problem that it is difficult to open, and when opening, the paper on the bonding surface is torn or the bonding surface of the opening mark becomes dirty. And so on.

Therefore, for example, when it is desired to use the envelope as a direct mail envelope, that is, when it is desired to print the envelope surface and use it as a notice surface, there is a complaint that the adhesive surface cannot be used as a notice space. Was.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention provides an easy-to-open seal even when sealed, and does not break the paper on the adhesive surface when opening, and furthermore, the opening mark on the adhesive surface is not stained. An object of the present invention is to provide an envelope suitable for direct mail or the like, since it is possible to print the adhesive surface and use it as a notice space.

[0006]

In order to solve the above-mentioned problems, an envelope according to the present invention comprises two films 3 and 4 adhered to a cover 2 and an envelope body 1, respectively. The film 3 and 4 are sealed with each other, and the two films 3 and 4 are peeled off to be opened.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. First, FIG. 3 shows a state before sealing. A transparent plastic film 3 is adhered to the inner surface of the lid 2 integrally formed with the paper envelope body 1 via an adhesive 5, and the transparent film 3 is similarly transparent to the outside of the film 3 via an adhesive 6. A plastic film 4 is bonded, and a release paper 8 is bonded to the outside of the film 4 via an adhesive 7.

The films 3, 4 and the adhesive 5,
6, 7 and the release paper 8 may be provided on the envelope main body 1 instead of the lid 2.

Further, as shown in FIG. 4, the two films 3 and 4 may be separated in advance and adhered to the lid 2 and the envelope body 1 respectively. That is, the film 4 is adhered to the envelope body 1 via the adhesive 7, the film 3 is adhered to the lid 2 via the adhesive 5, and the adhesive 3 is applied to the outside of the film 3 via the adhesive 6. The release paper 8 may be bonded and placed. Note that the release paper 8 and the layer of the adhesive 6
Instead, it may be provided outside the film 4 bonded to the envelope body 1.

Next, FIG. 5 shows a sealed state. When the cover 2 is folded back and superimposed on the envelope main body 1 after removing the release paper 8, if the state before sealing is as shown in FIG.
If the state before sealing is as shown in FIG. 4, the film 3 is bonded to the film 4 by the adhesive 6, and each of the films 3 is sealed.

Next, FIGS. 1 and 2 show the opened state. That is, when opened, the two films 3 and 4 are separated from each other, and one film 3 maintains the state of being adhered to the lid 2 and the other film 4 maintains the state of being adhered to the envelope body 1.

As described above, the two films 3 and 4 are separated from each other without separating the films 3 and 4 from the lid 2 and the envelope main body 1 because the paper lid 2 and the envelope main body 1 are separated from each other.
This is because the adhesive force between the plastic films 3 and 4 is weaker than the adhesive force between the plastic films 3 and 4.

In order to make the two films 3 and 4 easy to separate from each other and to surely prevent the films 3 and 4 from separating from the lid 2 and the envelope body 1, the two films 3 and 4 are used. An adhesive 6 having a low adhesive strength is used as the adhesive 6 for bonding the two, and a strong adhesive is used as the adhesives 5 and 7 for bonding the films 3 and 4 to the lid 2 and the envelope body 1, respectively. It is preferred to use.

The two films 3 and 4 are preferably V-shaped as shown in FIG. When the films 3 and 4 are V-shaped as described above, there is an advantage that the film is easily peeled and the opening property is improved as compared with the case where the film is in the form of a linear tape.

[0015]

The envelope of the present invention is as described above, and the envelope main body 1 and the lid 2 are bonded and sealed via the two films 3 and 4, so that the envelope can be easily opened. ,
Further, there is an advantage that the paper is not torn at the time of opening, and the opening trace is also hard to be stained and is beautiful. If the films 3 and 4 are made transparent, characters and the like can be printed as shown in FIG. 1 on the cover 2 and the place where the films 3 and 4 are bonded on the envelope body 1 and used as a notification space. Very suitable for direct mail. It should be noted that opening the films 3 and 4 in a V-shape as in the above embodiment has the effect of further improving the openability.
