Description

  The present invention relates to an envelope provided with easy-opening means by perforations, sealing means in an envelope by embossing and heat-welding and pressing, and document movement limiting means.

  Conventionally, as a method of opening a received envelope, a method of opening using a tool such as scissors or a paper knife, and a method of cutting the end of the envelope with a finger are generally used.

  The method of opening with the above tools is troublesome because tools such as scissors and paper knives must be prepared each time the envelope is opened. On the other hand, the method of opening with a finger is to open the envelope opening. Can not be opened in a clean state, and the document enclosed in the envelope moves in the direction of the opening and cuts or tears the edge of the document when opening There was a problem.

  Conventionally, proposals have been made to solve the above problems. For example, a “envelope provided with a perforation” (Patent Document 1) is proposed in which a perforation is provided in an opening on the sealing side of the envelope to facilitate opening.

  However, the proposal of the above-mentioned “envelope provided with a perforation” is that a notch-like continuous hole forming the perforation improves the sealing performance of the envelope by providing a perforation in the opening on the sealing side of the envelope. There is a problem in that the document enclosed inside is damaged by rain or water drops when the perforation is opened in the envelope, and the enclosed document moves to the perforation side in the envelope Therefore, when opening the perforation, there is a problem that the end portion of the document is damaged. The easy-opening means of the envelope as in the present invention, the sealing means in the envelope, and the document It was not an envelope provided with the movement restriction means.

  Conventionally, an “envelope” (Patent Document 2) in which a cutting thread for opening is provided along a folding line of the opening side flap of the envelope has been proposed.

  However, the proposal of the “envelope” requires an opening cutting thread to be provided at the opening side of the envelope, which leads to an increase in the manufacturing cost of the envelope and a complicated manufacturing process. Also, the end of the cutting thread protrudes outside the envelope, which is entangled in an automatic sorting device that sorts mail items, causing a failure of the device and damaging the envelope itself. As described above, there is a problem, and it is not an envelope provided with an easy-opening means for an envelope, a sealing means inside the envelope, and a document movement restricting means.

  In addition, a “simple opening envelope” (Patent Document 3) that provides a saw blade-like cardboard along the perforation to facilitate the opening action has also been proposed.

  However, the proposal of the above “easy opening envelope” is that the opening of the envelope is provided with cardboard in order to facilitate the perforation of the perforation. There is a problem that leads to an increase in the manufacturing cost of the envelope and a problem that it leads to an increase in the cost of manufacturing the envelope, and as mentioned above, it was not an envelope provided with an easy-opening means of the envelope, a sealing means in the envelope, and a document movement restricting means .

  Further, conventionally, an “envelope” (Patent Document 4) has been proposed in which a stopper, an adhesive portion is provided on the envelope lid, a perforation, a perforation, the back of the lid, or the envelope body.

  However, the proposal of the above “envelope” is a structure in which the knob is perforated with a finger and lifted upward, and the perforated cut-out perforation is cut into a V shape and opened. It is mechanically difficult to cut the bellows-like perforated perforation while expanding it into a V-shape by pulling upwards in an upward state (it is possible to cut in the direction of narrowing in a reverse V-shape), and it is somewhat cut off The bellows-like cut-out perforation is difficult to open unless it is cut one-by-side while inserting a finger into the perforation, and it is cumbersome and difficult. There is a problem that the document enclosed by the perforated hole of the paper gets wet with rain or water droplets, and as above, the easy-opening means of the envelope and the sealing hand in the envelope And was not envelope comprises movement limiting means of the document.

  Conventionally, there has been proposed a “cut-perforated envelope” (Patent Document 5) in which a bellows-shaped cut perforation is provided at the folded-back portion on the opening side of the envelope to facilitate the opening of the envelope.

  However, the proposal of the above-mentioned “cut-off perforated envelope” is that the end face of the bellows-like cut perforation to be cut is not attached to the back surface of the envelope, so that the end face of the perforation is an automatic sorting device that sorts mail items. Entangling may damage the envelope itself, and at the time of opening, the bellows-shaped cut perforation may be cut off in the middle to make the opening operation more troublesome. In addition, regarding the sealing performance inside the envelope, the envelope-side flap is simply folded in two, so the enclosed document is not completely sealed with glue or the like, and gets wet with rain or water drops. And the crease part cut off by the perforation remains slightly, so when removing the document from the envelope, the crease part seal must be opened with the fingertips and opened Further, as described above, the envelope is not an envelope provided with an envelope easy-opening means, a sealing means inside the envelope, and a document movement restricting means.

  Further, conventionally, an “envelope” (Patent Document 6) has been proposed in which a bellows-shaped cut perforation is provided on the back side of an envelope, and an outer tongue piece for sealing is covered from above to improve the appearance.

  However, the proposal of the above “envelope” is merely a proposal that simply covers the outer tongue piece for sealing the bellows-shaped cut perforation and improves the appearance of the appearance. As shown in FIG. 1 of Patent Document 6, there is a problem that a part of the accordion-shaped cut perforation protrudes from both ends of the outer tongue piece, so that the sealing performance cannot be secured. As shown in FIG. 2, in order for the outer tongue piece and the bellows-shaped cut perforation to be unsealed, the unsealed state shown in the drawing is not obtained unless the outer perforation line has a perforation line. Further, when taking out the document enclosed in the envelope in the state of FIG. 3 of Patent Document 6, the corner face of the document is caught by the remaining corners on the opening side of the envelope, which makes it difficult to take out the document. I, the same was not the envelope comprises a peelable means of the envelope, the movement limitation means of the sealing means as well as the documents in the envelope.

  Furthermore, an “envelope” (Patent Document 7) in which a releasable adhesive means is provided on the overlapping surface of a sealing piece of an envelope and a corresponding portion facing the sealing piece at the time of sealing has also been proposed.

  However, the above-mentioned “envelope” proposal is merely a proposal that uses a releasable adhesive means on the envelope sealing piece, and is dedicated to making it a one-sided open type against unauthorized opening by others. However, it is difficult to use in general households, and the peelability of the peelable adhesive that sticks the envelope can detect deliberate tampering. It cannot be said that there is an absolute reliability proposal that does not allow unauthorized opening, and as mentioned above, it was not an envelope with easy-opening means for envelopes, sealing means for envelopes, and means for restricting document movement. .

  The applicant of the present invention pays attention to the problems of the sealing properties that are contrary to the easy opening by the perforation applied to the envelope as described above, and the problems of the mobility in the envelope of the document. Under the idea of whether or not the problem can be solved by an easy means, the above-described easy-opening means by perforation, the sealing means in the envelope by the embossing crimping process and the thermal welding crimping process, and the document movement restricting means are provided. Developed an easy-open envelope that solves the problems of sealing performance, which is contrary to easy-openability due to perforations, and the problem of mobility in document envelopes. It is everything.
