Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an envelope, and particularly to an improvement in the structure of the opening portion of the envelope.

[Prior Art] Usually, an envelope 100 has an opening 101 at one end, as shown in FIG.
It is designed to be sealed by folding it back and sealing it.

[Problems to be Solved by the Invention] However, in the envelope 100 having such a structure, it is not uncommon for the contents 103 to move within the envelope 100 and collect in the opening 101 at the end during mailing or the like. For this reason, there is a drawback that there is a risk of accidentally cutting the contents 103 when cutting the seal using scissors or the like.

In order to solve this problem, an auxiliary seal is attached to the inside of the envelope at a distance from the opening, and this auxiliary seal keeps the contents at a distance from the opening. Publication No. 56-32050)
However, with this type of envelope, it is complicated to put in and take out the contents.

For example, when taking the contents in or out of the envelope, it is necessary to fold down or raise the auxiliary seal inside the envelope so as to cover the opening side of the contents. The operation becomes extremely troublesome. Moreover, this operation must be performed in addition to the operation of inserting and removing the contents from the envelope, making the operation of inserting and removing the contents extremely troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to provide an envelope that has a simple structure, allows the contents to be enclosed reliably away from the opening, and allows the contents to be easily taken in and taken out.

[Means for Solving the Problems] The present invention for achieving the above object provides that, in an envelope having an opening through which contents are taken in and taken out, a groove having a width approximately equal to the width of the opening is provided near the opening on the inner surface of the envelope. A long band is arranged, one end of the band in the longitudinal direction is stuck to one surface of the inner surface of the envelope, and the other end of the band is stuck to the other surface of the inner surface of the envelope. It is an envelope with

[Function] In the present invention configured as described above, when the contents are sealed in the envelope, the band placed near the opening on the inner surface of the envelope obliquely closes the opening. The band acts as a stopper material and reliably prevents the contents from moving toward the opening side.

In addition, when inserting or removing contents into an envelope, since only both longitudinal ends of the band are attached to the inner surface of the envelope, the opening can be opened by simply moving the band to one of the inner surfaces of the envelope. can be secured without interfering with or interfering with the loading and unloading of contents.

[Example] Hereinafter, an example according to the present invention will be described in detail based on the drawings.

Fig. 1 is a partially cutaway perspective view of an envelope according to an embodiment of the present invention, Fig. 2 a and b are sectional views taken along the - line in Fig. 1, and Fig. 2 a shows the sealed state. FIG. 2b is a cross-sectional view showing an unsealed state, and FIG. 3 is a rear view showing the back side of the same embodiment.

As shown in FIGS. 1 and 3, this envelope 1 has an opening 2 through which contents 4 such as stationery are inserted and removed.
and a seal 5 that folds back and seals the opening 2.

Particularly in this embodiment, a band 3 is provided near the opening 2 on the inner surface of the envelope 1.

This band 3 functions as a stopper to prevent the contents 4 from moving to the corner of the envelope 1, and has the same length l as the width L of the opening 2 and a predetermined band width w. There is. One end of the longitudinal direction is attached to the front surface (one side) 1f of the envelope 1, and the other end is attached to the back surface (other side) 1b.
It is provided so as to obliquely close the opening 2. The band 3 is usually made of thin paper of the same quality as the envelope 1, but it is also possible to use plastic film, paper thicker than the envelope 1, corrugated paper, metal foil, or composite materials thereof. In general, it is preferable to use paper or plastic film, which is inexpensive and easy to cut, and the material, thickness, size, etc. are selected as appropriate depending on the use of the envelope 1.

The band 3 is preferably provided as close to the end of the opening 2 as possible, that is, to the fold line 6 of the seal 5, in order not to restrict the actual space inside the envelope 1; It is also possible to set the cut point on the outside of the band 3 by placing it closer to the band 3, which is relatively hard.
This is suitable when adopting. The length of this band 3 is preferably approximately the same as the width of the envelope 1, but this length may be set as long as it can secure a practical opening area that does not hinder the insertion of the contents 4. but not limited to. Additionally, adhesive is normally used to bond the envelope 1 and the band 3, but if the envelope 1 and the band 3 are made of plastic film or are used as part of the plastic film, it may be possible to bond the envelope 1 and the band 3 by heat welding. be.

Next, the action will be explained.

In this embodiment configured as described above, when the contents 3 are sealed in the envelope 1, the band 3 disposed near the opening 2 on the inner surface of the envelope 1 closes the opening 2, as shown in FIG. 2a. Since the part 2 is obliquely closed, this band 3 acts as a stopper material to prevent the contents 4.
This will reliably prevent the movement of the material toward the opening 2 side.

This prevents the contents 4 from being accidentally cut if the bag is opened at a location where the band 3 is present or at a location closer to the opening 2 than the band 3.

On the other hand, when loading and unloading the contents 4 into the envelope 1, as shown in FIG. The opening 2 can be secured by simply moving the envelope 1 to either one of the inner surfaces, for example, the back surface 1b, and the contents 4 can be easily taken in and taken out without being obstructed or obstructed.

To bring this band 3 to either side of the inner surface of the envelope 1, use your finger or the like to bring the band 3 to either side of the inner surface of the envelope 1, or to move the band 3 to either side of the inner surface of the envelope 1.
The envelope 1 may also be deformed together with the envelope 1.
In this way, loading and unloading the contents 4 from the envelope 1 is almost the same as normal loading and unloading operations, and the envelope can be handled in the same way as a normal envelope.

Therefore, in this embodiment, with the simple structure of arranging the band 3 near the opening on the inner surface of the envelope 1, the contents 4 can be reliably sealed away from the opening 2, and, This means that the contents 4 can be taken in and out easily.

In the above-mentioned embodiment, the band 3 is provided on the sealing portion, but the band 3 is not limited to this, and it is also possible to provide it on the side of the bottom opening 2b that has been closed in advance, or on both sides. Both end openings 2, 2
When the band 3 is provided on b, the envelope can be reliably opened without cutting the contents 4 no matter which side of the envelope is opened. Moreover, the envelope 1 can be implemented either vertically or horizontally.

[Effects of the invention] As described above, according to the invention, a band having approximately the same length as the width of the opening is arranged near the opening on the inner surface of the envelope, and one end in the longitudinal direction of this band is Since it is attached to one side of the inner surface of the envelope and the other end of the band is attached to the other side of the inner surface of the envelope, it is possible to reliably prevent the contents from moving toward the opening side with a simple structure. be able to. Therefore, as long as the package is opened at the location where the band is present or at a location closer to the edge, there is no chance of accidentally cutting the contents.

Furthermore, since only the ends of the envelope band are attached to the inner surface of the envelope, an opening can be secured by placing the band on either side of the envelope, preventing the contents from being taken in or taken out. It can be done easily without having to do anything.
