Utility Model Registration No. 3082918 Utility Model Registration No. 32004032

In the envelope type that can be used repeatedly, which is the prior art disclosed in Patent Document 1, a material having a property different from that of the envelope body is used in the portion of the storage portion where the tongue and the tongue are combined. Similarly, the Maggi tape (registered trademark) seal and the maltack seal are also expensive.
Seals that can be peeled over and over can reduce costs, but with repeated use, adhesion becomes weak and loses function.
In the envelope which is the prior art disclosed in Patent Document 2, since the function is integrated with the envelope body, the function cannot be attached to other envelopes. Moreover, the appearance of the hooking nail for insertion is bad and influenced by the design.
An object of the present invention is to provide a fastener that is simple in structure, compact, inexpensive, and excellent in design.

It is a sealing type sealing fastener composed of two combinations of a nail installation part that is attached to the center tip of the envelope and a hanging part that is attached to a position closer to the top of the envelope storage section.
The nail installation part has a substantially square shape and is provided with a claw-side adhesive part with a width of about 1 cm along the edge of the upper end, and a slit that swells in a semicircular shape toward the adhesive part at the center below the adhesive part A claw part is formed to enlarge the adhesion part side of the slit along the outer line of the semicircular arc, and a simple and easy-to-understand silhouette cutout such as an animal or a car is provided. Nail side illustrations and marks that are combined with the silhouette into a single pattern are included in the nail.
The door part is widened so that it is wider than the nail width, and the door side adhesive part is provided, and the door side illustrations and marks are put on the surface. The shape of the hook part with the highest functionality is an elongated strip shape on the left and right. It is also possible to substitute shapes that emphasize appearance, such as circles, squares, character shapes such as bears and cats, and mark shapes. Only in the case of a strip-shaped body, there are provided adhesive portions with a width of about 1 cm at both the left and right ends, a folding line is provided along the inner edge of the adhesive portion on each hook side, and the lower center is A dent that is gently recessed from the outside to the inside is provided.
The nail installation parts are affixed to the center tip of the envelope, and the hook parts are affixed to a position close to the center of the opening on the storage side. When the adhesive part on the hanging part side of the hanging part is pasted on the envelope, there is a gap between the envelope body and the center of the hanging part, and there is an insertion part into which the claw part can be inserted.
It has a structure that prevents the fall of stored items that can fix the tongue by inserting the claw part into the insertion part, and a structure that changes the appearance of the illustration before and after inserting the claw part.
In addition, when the structure of the present invention is incorporated as an integral type with an envelope or a card, the nail installation parts are directly provided with the structure, and the hook parts are directly installed at a position near the top of the storage part on the opening side. The adhesion part of each nail | claw installation part and a hook part can be abbreviate | omitted, the structure which provides a nail | claw installation part directly in a tongue, and provides a linear slit longer than the width | variety of a nail | claw part as an insertion part is preferable.

In the present invention, roughly six effects can be expected.
The first is a fastener that is simple in structure, compact, inexpensive, and excellent in design.
Second, it can be expected to have a function to prevent the items stored inside the envelope from being dropped when the opening side is upside down.
In the state where the tongue is folded, the claw part provided with a slit that swells in a semicircular arc shape or the like facing the direction of the tongue will be wider than the linear slit arranged directly on the main body or the claw width Since the nail | claw part is inserted from the gap | interval of the belt | band | zone which provided the adhesion part and opened the space | gap, a nail | claw part will be caught in a belt | band | zone and it becomes possible to fix a tongue firmly.
Thirdly, by providing an adhesive part for sticking the nail installation part and the hook part to the envelope, it is affixed to the envelope as a seal, and even for envelopes that do not have the function of preventing the fall of the stored item, it is easy to prevent the stored item from falling. It is possible to have this function.
Fourth, when fixing the tongue, it is possible to fix the tongue by using a combination of the nail installation part and the hook part without using seals or adhesives. have.
The fifth is that the weight of the stored item is loaded on the tongue when the unsealed side is upside down, but it can be raised from its ability to withstand that load. This is because the structure used for bags such as telephone cards in the prior art has a structure in which the claw part at the tip of the tongue is inserted into the slit of the storage part, so it has a weight such as coins when the opening side is inverted. Without being able to withstand the weight of the containment, the tongue opens and drops the containment. However, in the present invention, since the claw portion is caught by the insertion portion and the tongue can be firmly fixed, the load on the claw portion and the tongue can be reduced. In addition, the band used for the envelope of the prior art disclosed in Patent Document 2 is wide enough to allow the envelope to be taken in and out, whereas in the present invention, only the width into which the claw portion can be inserted is required. In addition, since the adhesive part is close, the strength can be increased. And if it is the form which opens a space so that it may become wider than a nail width and provides an adhesion part, an insertion part can also provide an adhesion part not only on an adhesion part of both ends, but also on the upper part of a hook part. The load on the parts can be reduced and the strength can be increased.
The sixth is a sheet material such as cardboard and YUPO, which is made of a low-priced material, and can reduce costs.
The seventh is that you can expect the effect to show fashionable and cute patterns, illustrations and marks.
Before inserting the nail, the silhouette cut out, the illustration on the nail, the illustration of the silhouette cut out and the part of the hook that can be seen between the nail are combined to express one shape. When the nail is inserted into the insertion part, the nail is not visible, and when the illustration is viewed from the cutout of the silhouette, the appearance changes and the effect is as if the illustration is changed.
As an example, put a cat face silhouette in the cutout of the silhouette, draw a cat face with rounded eyes on the nail part, and put an illustration of a cat with a laughed expression centering on the overlapping part of the nail part of the insertion part. Then, after inserting the claw part, the cat who had rounded eyes before inserting, the illustration of the nail part entered under the hook part, and the laughing cat of the illustration of the hook part from the cutout of the silhouette It is possible to look into it and make it appear as if the cat laughed.
Also, if you put a cutout silhouette and a claw on a bear, and put a rabbit illustration on the hook part, you will be able to develop a unique and playful design that turns the bear into a rabbit when opened.
Eighth, by cutting out simple and easy-to-understand silhouettes such as animals and cars along the edge of the slit along the outer line of the semicircular arc of the slit of the nail part, the simple appearance of the semicircular arc is improved, and the nail It is possible to show the installation parts in a stylish design.
Ninth, if the same structure fastener is incorporated into a tri-fold card or a card with a double fold, the vision will change and the card can be opened and sealed freely.
The tenth is a thin and compact fastener.
The eleventh part is a part with an adhesive part with a width of about 1 cm along the top edge of the nail installation part, and a slit that swells in a semicircular arc shape to the adhesive part side at the center below the adhesive part. Between the two claws, bend the adhesive part into a valley. If you attach the folded part to the edge of the notebook or file so that the folded valley fits, and paste the hook part so that the space between the bonded parts overlaps the nail part, the file with the notebook or multiple pages Can also be used as a fastener.
The twelfth is the case where the file is turned upside down when the product of the present invention is attached to a storage clear file of the type where the upper side of the pocket file used for the loose leaf file or the two hole file is an opening / closing part. It can also be used as a fastener for preventing the fall of stored items. It is also possible to integrate the fastener with each of the pocket file used for the loose leaf file or the two-hole file.
