An inconvenient situation occurs in which the bottom side of the envelope body 52 is unsealed and the bottom side of the envelope body 52 is unsealed.

  As a result, a person other than the legitimate addressee (illegal person) extracts the letter paper 57 from the opened bottom side of the envelope body 52 and interprets it, then returns the letter paper 57 into the envelope body 52, and the bottom sealing piece By pasting 55 so as to be in the original state, it is possible to restore the postal matter 58 before opening.

  And even if a legitimate addressee opens the restored postal matter 58, it is difficult to determine that it has already been opened by an unauthorized person.

  That is, the conventional general envelope 51 includes a problem that an unauthorized act of unauthorized opening by an unauthorized person is easily performed or is actually performed.

  In addition, regarding envelopes used as postal items, it is conventionally desired that the envelopes used as envelopes be reusable rather than used up only once, from the viewpoint of resource saving of paper sheets used as envelopes.

  Patent Document 1 discloses an envelope configured to cause breakage or deformation of a container when a third party tries to open it by using a material that is provided with a cut or is significantly stretched at a sealing part in the container opening. A form of storage is disclosed.

  However, in the case of the storage body of this Patent Document 1, it has been necessary to add a special element such as providing a notch in the sealing portion or using a material that extends significantly.

  In Patent Document 2, a field for sending a credit address is provided at the top of the cover, and a perforation line extending over the entire length in the width direction is provided on the cover below the field, and the back line corresponds to the above-mentioned slit line. In addition, a perforated cutout line that can form a sticking tongue piece is provided over the entire length in the width direction, and on the back paper surface below the cutout line, a sending address at the time of reply, which is a sender at the time of outgoing communication, is printed. When sending and receiving, the destination is written above the line on the cover, and when replying, the top and bottom are cut along the line to make a small reply envelope consisting only of the bottom. A postal envelope is disclosed that can be sent and received with an envelope.

  However, in the case of the envelope for the mail of this patent document 2, although it is possible to send and return with a single envelope, the form of the envelope itself changes greatly between the time of outgoing and the time of reply. It was.
