Description

  The present invention relates to an unauthorized opening discrimination envelope.

  In recent years, unauthorized opening of envelopes has become a problem. For example, if a third party carefully peels off the flap of the envelope, looks at the contents of the envelope, and then glues and seals it again, the person may not notice the tampering. That is, the contents of the envelope may be stolen by a third party without the knowledge of the person.

As means for preventing such unauthorized opening, for example, the following documents are disclosed. Patent Document 1 discloses a package (envelope) capable of discriminating unauthorized opening. This package includes a synthetic resin laminate at a portion where a flap is attached. Then, when the flap is peeled off, the ink layer in the laminated body is destroyed, and a predetermined character appears, so that the tampering can be determined at a glance. Further, Patent Document 2 discloses an envelope that can be confirmed to be tampered with by providing a break slit at a portion where a flap is applied.

  The conventional one has a complicated structure for confirming unauthorized opening, and it has been difficult to manufacture at low cost. In addition, there has been a demand for means capable of discriminating unauthorized opening more simply and more effectively than conventional ones.

  In view of the above, the main object of the present invention is to provide an envelope that can be easily, inexpensively and effectively discriminated from tampering.

  In the present invention, a notch having a predetermined shape is formed on the back surface of the envelope, and the notch provides an unauthorized opening discrimination envelope formed at a position where a part of the notch is covered by the flap when the flap is folded.

  In this envelope, a cut is formed at the above-described position, so that when the envelope is opened (when the flap is peeled off), the cut is broken and the envelope is opened while being adhered to the flap. Therefore, unauthorized opening can be easily identified.

  Further, in this envelope, a part of the cut is formed at a position covered by the flap when the flap is folded back, and the other part of the cut is formed at a position not covered by the flap at the time of sealing. Therefore, it can be confirmed from the appearance that a cut is formed even when sealing (when the flap is folded back). Therefore, unauthorized opening by a third party can be suppressed.

  In addition, the tamper-evident discrimination envelope according to the present invention may be configured such that the uncut portion of the cut is formed at a position that is not covered by the flap when the flap is folded back.

  In this configuration, the uncut portion of the incision is torn at the time of opening, and the trace of opening is clearly left. it can. Further, since unauthorized opening can be easily determined from the appearance, unauthorized opening by a third party can be suppressed.

  In addition, when an envelope is formed by bending a sheet and has an affixed portion in which the sheet is laminated and affixed to the bottom or body portion of the backside of the envelope, a cut with a predetermined shape is formed on the backside of the envelope, and the incision is A part of the sheet inside the portion may be formed so as to protrude from the pasted portion, and the uncut portion of the cut may be provided at a position protruding from the pasted portion.

  With this configuration, even if the pasting part other than the flap is peeled off and the tampering is performed, the tampering can be easily identified from the appearance. Further, since unauthorized opening can be easily determined from the appearance, unauthorized opening by a third party can be suppressed.

  According to the present invention, it is possible to easily determine whether an envelope has been tampered with.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a schematic external view showing an example of an unauthorized opening discrimination envelope according to the present invention.

  In FIG. 1, an unauthorized opening discrimination envelope A includes an envelope body (back surface) 1 and a flap 2 that is folded back when sealed, and a cut 3 having a predetermined shape is formed on the envelope back surface 1. In addition, the code | symbol 11 shows the position where the edge 21 of the flap 2 contacts the envelope back surface 1 when the flap 2 is folded back.

  The cut 3 is formed at a position 12 where a part (reference numeral 31) of the cut 3 is covered by the flap 2 when the flap 2 is folded back. That is, the cut 3 is formed at a position 12 where a part (reference numeral 31) is covered by the flap 2, and is formed at a position 13 protruding from the position 12 where the other part (reference numeral 32) is covered by the flap 2.

  With the above configuration, since the cut remains adhered to the flap even when the flap is opened (when the flap is peeled off) (details will be described later), the unauthorized opening can be easily identified. In addition, as indicated by reference numeral 32 in FIG. 1, it is possible to confirm that a cut is formed from the appearance even when sealing (when the flap is folded back), so that unauthorized opening by a third party can be suppressed.

  In addition, in FIG. 1, the uncut portion 33 of the cut 3 is formed at a position 13 that is not covered by the flap 2 when the flap 2 is folded back. By forming the uncut portion 33 of the cut 3 at this position (symbol 13), the uncut portion 33 is torn at the time of opening, and the opened trace remains clearly. For example, a third party attaches cleanly after unauthorized opening. Even when it is reattached, it is possible to easily identify unauthorized opening from the appearance.

  In addition, the shape of the notch | incision 3 will not be specifically limited if it is a thing of the state which the envelope back surface 1 and a part connected. As the shape of the notch 3, for example, a substantially U shape, a substantially U shape, a substantially V shape, a substantially rectangular shape, a substantially circular shape, a substantially elliptical shape, a substantially triangular shape, a substantially star shape, a substantially trapezoidal shape, etc. Applicable.

  FIG. 2 is a schematic view showing a state where the tampering-determining envelope according to the present invention is tampered with.

  At the time of sealing, the flap 2 of the envelope A is folded back, and the envelope back surface 1 and the flap 2 are bonded with an adhesive such as glue. Therefore, at the time of sealing, the notch 3 and the flap 2 formed in the envelope back surface 1 are also bonded. Therefore, for example, when the flap 2 is peeled off and the tampering is performed (arrow X), as shown in FIG. 2, the notch 3 is torn and opened with the flap 2 adhered (reference numeral 3 ′, arrow). See Y). Therefore, unauthorized opening can be easily identified.

  In addition, as shown in FIG. 2, when the uncut portion 33 of the cut 3 is formed at a position 13 that is not covered by the flap 2 when the flap 2 is folded back, the uncut portion 33 is broken and opened when opened. Since 34 remains clearly, for example, even when a third party reapplys cleanly after tampering, tampering can be easily identified from the appearance.

  FIG. 3 is a schematic external view showing another example of an unauthorized opening discrimination envelope according to the present invention.

  In FIG. 3, the unauthorized opening discrimination envelope A includes an envelope body (back surface) 1, a flap 2 that is folded back at the time of sealing, a bottom pasting portion 15 that is folded back to the bottom 14 of the envelope back surface 1, and a sheet is laminated and pasted. A body sticking portion 17 in which a folded sheet is attached to each portion 16 is provided. The cut 3 is formed at the same location as in FIG. 1 (reference numeral 3A), and a part of the bottom sticking portion 15 and the body sticking portion 17 protrudes from the sticking portion (reference numerals 15, 17). (3B and 3C, respectively).

  By forming cuts (reference numerals 3B and 3C) on the sheet inside the bottom sticking part 15 and / or the trunk sticking part 17, the sticking parts (symbols 15 and 17) other than the flap 2 are peeled off and tampered with. In the case of a tampering, the tampering can be determined.

  Similarly to the above, by providing the uncut portions (reference numerals 33B and 33C) of the cuts (reference numerals 3B and 3C) at positions protruding from the attached portions (reference numerals 15 and 17), the affixed parts other than the flap 2 (reference numerals) Even when 15 and 17) are peeled off and unauthorized opening is performed, the unauthorized opening can be determined from the appearance.

  In addition, the shape and configuration of the cuts (reference numerals 3B and 3C) can be the same as those of the cut 3 shown in FIG. Further, the position and the number of the notches 3 (reference numerals 3A, 3B, 3C, etc.) can be arbitrarily determined according to the purpose, the design of the appearance, etc., as long as they are within the above-mentioned range.

  The unauthorized opening discrimination envelope according to the present invention can be manufactured easily and inexpensively. Therefore, the manufacturing cost can be suppressed. Moreover, there is a possibility that the unauthorized opening of the envelope can be suppressed by the development of the unauthorized opening discrimination envelope according to the present invention.
