It had a structure in which it was folded back and closed with adhesive.

(Problem to be solved by the invention) Regular postage is divided into fixed-size mail and non-standard-size mail, and fixed-size mail is more advantageous in terms of cost.
Standard-sized mail items are defined as items with dimensions of 9 x 14 cm or more, 12 x 23.5 cm or less, and a thickness of 1 cm or less. However, a 3.5-inch floppy disk is approximately 90 mm in length and width, and in a packaging case that is sized to fit regular mail, the length in the vertical direction is longer than that of a floppy disk, and the floppy disk stored in the packaging case is There was a problem with the disks floating around and affecting floppy disks.

The present invention was developed in view of the above-mentioned problems.The case is formed to a size that fits standard-sized mail, and the packaged items such as 3.5-inch floppy disks stored in the case do not move around. The purpose is to provide packaging cases for mailing.

[Structure of the idea]

(Means for Solving the Problems) The mailing packaging case of the present invention consists of an elongated rectangular case body made of cardboard, and a notch recess is formed in the back of the case body from the center of the opening edge at one end. A holding piece that can be separated from the inner edge and is folded back inside the case body to hold the stored object is formed in this recessed part, and a holding piece that is folded back to the back side on the front side of one end of the case body on the opening side is formed. The present invention is characterized in that a closing piece that closes the cutout recess together with the opening extends out.

A packaging case for mailing according to claim 2 is characterized in that, in the packaging case for mailing according to claim 1, the circumferential side of the case body is an inclined side surface that narrows from the periphery of the front part to the periphery of the back part. It is something.

(Function) In the mailing packaging case of the present invention, when storing the packaged item in the case body from the opening, the holding piece is folded back in advance from the inner end side of the notch recess inside the case body, so that the holding piece can be held in place. Even a packaged object such as a 3.5-inch floppy disk whose length in the longitudinal direction of the case body is shorter than that of the case body is prevented from moving in the longitudinal direction of the case body. Next, the closing piece is folded back and adhered to the back surface of the case body, thereby closing the notch recess along with the opening of the case body. You can then write the addressee on the front, affix a stamp, and send it as a postal item.

Furthermore, when opening the package, the opening is opened by opening the closing piece and separating the holding piece, and the holding piece is removed, allowing the packaged item to be taken out from the opening.

Further, in the mailing packaging case of claim 2, since the circumferential side of the case body is an inclined surface that narrows from the periphery of the front part to the periphery of the back part, even an object to be packaged that is thinner than the thickness of the case can float in the thickness direction of the case.
