Description

  The present invention relates to a concealment postcard that makes it possible to ensure the confidentiality of the content described in the entry field of a postcard piece of paper, and is particularly seen by a third party such as a telephone number, address, name, and password. It relates to concealment postcards that can keep confidential information that you do not want to keep.

  Conventionally, as a concealing postcard, a postcard paper piece of the same size and a concealing paper piece are joined together in a foldable manner, an entry field is provided on the inner surface of the postcard paper piece, and a re-peeling adhesive is provided on the inner surface of the concealing paper piece. A concealed postcard having a structure in which a release paper is applied to the surface of the cover is known.

  However, in the concealed postcard with the above configuration, the customer brings back the concealed postcard from a financial institution, etc., fills in a predetermined item in the entry field on the inner surface side of the postcard paper piece, stamps it, and then sticks it on the concealed paper piece. The release paper is peeled off, and the re-peeling adhesive applied to the masking paper piece is attached to the postcard paper piece so as to cover the entry field on the inner side of the postcard paper piece. Because the re-peeling adhesive that has been removed has re-adhesive properties, a third party can peel off the concealed paper piece in the middle of delivering a single postcard, and see the contents entered in the entry field. If the cover sheet piece is pasted again after viewing the contents, it will not be known whether it has been seen by a third party, so there is a concern that confidentiality is not perfect.

  For this reason, as a technical document filed prior to the present invention, a postcard paper piece and a concealing paper piece of the same size are connected so as to be foldable via a fold line, and a predetermined item is entered on the inner surface of the postcard paper piece. An adhesive layer that is provided with a predetermined width along the edge facing the crease line and that cannot be peeled off is formed, and a release paper is laminated to cover the adhesive layer, and the inner surface of the masking paper piece A weak pressure-sensitive adhesive layer that is releasably bonded is formed, and a release paper is attached to cover the weak pressure-sensitive adhesive layer, and only the width of the adhesive layer along the edge facing the crease line of the masking paper piece It consists of a perforation formed at a position close to the inside, and fills in the personal information etc. in the entry field printed on the inner surface of the postcard paper piece, and the cover paper piece covers the entry field of the postcard paper piece By sticking to the inside of the description written in the entry column Postcards with concealed contents can be posted, and there is no risk that the concealed paper pieces will peel off from the postcard paper pieces during handling during delivery. There is a document that discloses a concealment postcard that can be reliably performed (see, for example, Patent Document 1).

In addition, an information entry piece having an information entry field, a concealment piece connected to one side of the information entry piece and concealing at least the information entry field, and the information entry piece and the concealment piece can be re-peeled and reattached A separation structure, a strong adhesion portion that bonds at least one end portion in a normal state with the information entry piece and the concealment piece bonded together, and a separation schedule that separates the strong adhesion portion when opened There is a document that discloses a concealment label sheet that can confirm the fact that concealment information has been skimmed without incurring a large cost (for example, see Patent Document 2).

An opening perforation for opening the concealing postcard is provided in the concealing paper piece at a position close to the inner side by the width of the adhesive layer along the edge facing the crease line of the concealing paper piece. However, the opening perforation disclosed in the above-mentioned Patent Document 1 is provided on the concealment paper piece mainly for the purpose of opening the concealment postcard, so that the perforation for opening other than the portion provided with the perforation for opening No consideration is given to breaking the region. In addition, since the opening perforation is a straight perforation, it is possible to cut the masking paper piece cleanly along the opening perforation, so that a third party other than the recipient can open it. Even if you open the concealed postcard along the eyes, if you return the concealed postcard to the state before opening it, you will recognize by looking at whether or not the concealed postcard was opened along the opening perforation. Will not be able to.

  Moreover, the patent document 2 mentioned above provides the strong adhesion part which adhere | attaches so that at least one end part may not peel in a normal state similarly to the patent document 1 mentioned above, and prevents opening by a third party other than the recipient. In addition, the concealment piece is provided on the concealing piece for separating the strong adhesion portion at the time of opening. However, since the separation planned portion disclosed in Patent Document 2 is provided on the concealing piece mainly for separating the strong adhesion portion at the time of opening, an area other than the portion where the separation planned portion is provided is provided. No consideration is given to breaking. In addition, since the planned separation part is formed with straight micro perforations, the concealment piece can be cut cleanly along the planned separation part, so that a third party other than the recipient can perform the separation planned part. Even if the concealment postcard is opened along the line, if the concealment postcard is returned to the state before opening, it cannot be recognized at a glance whether or not the concealment postcard was opened along the planned separation part. become.

At this time, in the concealing postcard in the present embodiment, at least a part of the concealing paper piece (1) and the postcard paper piece (2) is completely adhered by the strong adhesive layer (10).

  As a result, even if a hidden postcard concealing the entry contents in the entry field (2a) provided on the inner surface of the postcard paper piece (2) is posted, the hidden paper piece (1) and the postcard paper piece (2 ) Can be peeled off, and it is possible to securely maintain the confidentiality of the contents entered in the entry field (2a).

  Further, in the concealment postcard in this embodiment, the opening weakening line (7) for opening the concealment postcard and the breaking weakening line (8) are provided on the concealment paper piece (1). When a third party other than opens the concealment postcard along the opening weakening line (7) for opening the concealment postcard, the breaking weakening line (8) applied to the concealment paper piece (1) The masking paper piece (1) is irregularly broken so as to deviate from the planned opening direction (9) along the opening weakening line (7), and as shown in FIG. 1 (d), the direction other than the planned opening direction (9) A break line (11) is formed in the region, and irregular opening marks are left on the masking paper piece (1) itself. As a result, when the concealment postcard is opened, the concealment piece (1) is destroyed to such an extent that the concealment piece (1) cannot be restored to its original state. It becomes possible to recognize the concealment postcard at a glance and to prevent opening of a third party other than the recipient.

  When the recipient opens the concealed postcard, the recipient opens the concealed postcard along the opening weakening line (7) for unsealing the concealed postcard, and the postcard piece (2) and the concealed piece (1) It is possible to browse the entry contents entered in the entry field (2a) on the inner surface of the postcard paper piece (2). At this time, the masking paper piece (1) is broken by the breaking weak line (8), but there is no problem because it is an authorized recipient.

  Next, the shape of the breaking weakening line (8) and the opening weakening line (7) applied to the masking paper piece (1) will be described with reference to FIGS.

  The shape of the breaking weak line (8) to be applied to the masking paper piece (1) of the present embodiment is such that when opening the masking postcard along the opening weakening line (7) for opening the masking postcard, the masking paper piece The wrapping paper piece (1) is irregularly broken so as to deviate from the planned opening direction (9) along the opening weakening line (7) by the breaking weakening line (8) applied to (1). As shown in (a), if it is a shape that can form a break line (11) in a region other than the planned opening direction (9) and leave irregular opening marks on the masking paper piece (1) itself, It is possible to apply a breaking weak line (8) of any shape to the masking paper piece (1), for example, a wedge shape, a V shape, a U shape, a W shape, a Y shape, a semicircle It is possible to apply a breaking weak line (8) such as shape to the masking paper piece (1).

  As shown in FIG. 2A, the shape of the breaking weak line (8) is a postcard when the cover postcard is opened along the opening weak line (7) for opening the cover postcard. Guided so as to deviate from the expected opening direction (9) along the opening weakening line (7) under the influence of the force (the force in the peeling direction A) when peeling the paper piece (2) and the masking paper piece (1). It is preferable that the shape be That is, it is preferable that the breaking weakening line (8) is provided substantially in parallel with the peeling direction A when peeling the postcard paper piece (2) and the masking paper piece (1). Thereby, since the effect | action with respect to the fracture | rupture direction (B) of the weakening line (8) for a fracture | rupture acts largely, it becomes possible to make it easy to form a fracture line (11) in areas other than the opening direction (9). Become.

  In addition, it is preferable to form the weakening line (8) for a fracture | rupture in the substantially square-shaped shape used as one set by two. That is, as shown in FIG. 2B, the angle θ from the planned opening direction (C) side for opening the concealment postcard to the weakening line for breaking (8) is an obtuse angle (90 <θ <180). It is preferable to do. Thus, not only when opening along the opening weakening line (7), but also when trying to open from the upper right side or lower right side of the masking paper piece (1), the postcard paper piece (2) and the masking paper piece (1 ) And the force (the force in the peeling direction A) is easily affected, and the cover paper piece (1) can be easily broken. Further, the breaking weakening line (8) is not limited to the single breaking weakening line (8) as shown in FIGS. 2 (a) and 2 (b), but the postcard paper piece (2) and the concealing paper piece. If it is a shape that can break the region other than the one provided with the opening weakening line (7) when peeling (1), it is intermittent as shown in FIGS. 2 (c) and 2 (d) It is also possible to apply the broken line for breaking (8) to the masking paper piece (1).

  It should be noted that the weakening line for break (8) shown in FIG. 2 is the same as the postcard piece (2) and the concealment piece (1) even when opening from both the upper right side and the lower right side (scheduled opening direction C) of the concealment postcard. In order to make it easier to be affected by the force (peeling force in the peeling direction A) at the time of peeling, a line-symmetric breaking weakening line (8) (substantially U-shaped) is applied to the masking paper piece (1). However, for example, as shown in FIG. 3 (a), when only the case of opening from the lower right side of the concealed postcard (scheduled opening direction C) is considered, the postcard paper piece (2) and the concealed paper piece (1 ) To the concealed paper piece (1) with the same shape of the weakening line for breaking (8) that is easily affected by the force (the force in the peeling direction A) when peeling from the lower right side of the concealing postcard (scheduled opening direction C) It is also possible to apply. Also, as shown in FIG. 3B, when considering only the case of opening from the upper right side of the concealment postcard (scheduled opening direction C), the postcard paper piece (2) and the concealment paper piece (1) are combined. It is also possible to apply a breaking line (8) having the same shape that is easily affected by a force (a force in the peeling direction A) when peeling from the upper right side (scheduled opening direction C) to the masking paper piece (1). Is possible. Further, the method of applying the breaking weakening line (8) to the masking paper piece (1) may be through-cut, half-cut or stamped. Any method can be used as long as the masking paper piece (1) can be broken. A line (8) can be applied to the masking paper piece (1). In order to ensure the breakage of the masking paper piece (1), it is preferable to apply a breaking weakening line (8) to the masking paper piece (1) with a through-cut.

  Moreover, as the shape of the opening weakening line (7), if it is a shape that leaves a part of the concealment paper piece (1) adhered to the strong adhesive layer (10) in an inseparable manner on the postcard paper piece (2), The opening weakening line (7) can be applied to the masking paper piece (1) in any shape. In addition, as the shape of the opening weakening line (7), as shown in FIG. 2 (a), an equidistant weakening line is applied, or as shown in FIG. 2 (b), a weakening line of different intervals is applied. It is possible to Further, the method of applying the opening weakening line (7) to the masking paper piece (1) may be through-cut, half-cut or stamped, and the postcard paper piece (1) and the masking paper piece (2) are opened. As long as it can be opened along (7), the opening weakening line (7) can be applied to the masking paper piece (1) using any method. In order to facilitate the opening of the postcard paper piece (1) and the masking paper piece (2), it is preferable to apply a weakening line for opening (7) to the masking paper piece (1) by through-cutting.

  Moreover, as shown in FIG. 4, FIG. 5, the force (peeling direction A) at the time of peeling a postcard paper piece (2) and a masking paper piece (1) with respect to at least one edge part of the opening weakening line (7). It is also possible to provide a breaking weakening line (8) that is susceptible to the influence of For example, as shown in FIG. 4A, when considering opening the concealment postcard from the lower right side (scheduled opening direction C) of the concealment postcard, as shown in FIG. Is defined as the lower right side, the crease line (6) that is easily influenced by the force (the force in the peeling direction A) when peeling from the lower right side (scheduled opening direction C) of the concealed postcard. It is preferable that the break weakening line (8) inclined in the upper left direction toward the upper end of the opening is applied to the end of the opening weakening line (7). Thereby, when the concealment postcard is opened from the lower right side of the concealment postcard (scheduled opening direction C), it becomes possible to easily form the break line (11) on the concealment paper piece (1). In the case of the configuration shown in FIG. 4 (a), as shown in FIG. 4 (b), when the cover postcard is opened from the upper right side of the cover postcard (scheduled opening direction C ′), the opening weakening is performed. When peeling progresses along the line (7) and reaches the end of the opening weakening line (7), the force when peeling from the upper right side of the concealment postcard (the opening direction C ′) (force in the peeling direction A) ), A force acts in the direction of “arrow B” in FIG. 4B, and the masking paper piece (1) is peeled off from the expected opening direction (C ′). Then, the peeling that has been deviated from the planned opening direction (C ′) becomes the receiving portion by the breaking weakening line (8), the peeling proceeds along the breaking weakening line (8), corrects the peeling direction, and opens. When the starting end of the weakening line (7) is reached, peeling proceeds along the opening weakening line (7). That is, the breaking weak line (8) corrects the opening direction. Thereby, when the concealment postcard is opened from the upper right side (opening planned direction C ′) of the concealment postcard, it is possible to cleanly peel along the opening weakening line (7). In this way, with the peeling start part as a reference, the breaking weakening line (8) substantially along the peeling direction toward the crease line (6) is provided so as to protrude from the end of the opening weakening line (7). In the case where the concealment postcard is opened from the side defined as the peeling start part, it becomes possible to easily form the break line (11) with respect to the masking paper piece (1), and the side defined as the peeling start part When the concealment postcard is opened from the opposite side, it can be peeled cleanly along the opening weakening line (7).

  In addition, as shown in FIG. 5A, when considering opening the concealment postcard from the upper right side (scheduled opening direction C ′) of the concealment postcard, as shown in FIG. Is defined as the upper right side, the crease line (6) that is easily influenced by the force (the force in the peeling direction A ′) when peeling from the upper right side (scheduled opening direction C ′) of the concealment postcard. It is preferable that the break weakening line (8 ′) tilted in the lower left direction toward the left side is applied to the end of the opening weakening line (7). Thereby, when the concealment postcard is opened from the upper right side of the concealment postcard (scheduled opening direction C ′), it is possible to easily form the break line (11) on the concealment paper piece (1). In the case of the configuration shown in FIG. 5A, when the cover postcard is opened from the lower right side (scheduled opening direction C) of the cover postcard, as shown in FIG. The weak line (8 ′) serves as a receiving portion, and can be peeled cleanly along the opening weak line (7).

  In addition, as shown in FIG. 5B, in consideration of opening the concealment postcard from both the lower right side (scheduled opening direction C) and the upper right side (scheduled opening direction C ′) of the concealed postcard. The weakening line for breaking (8), which is easily affected by the force (the force in the peeling direction A) when peeling from the lower right side of the concealment postcard (scheduled opening direction C), is one of the weakening lines for opening (7). A weakening line for breaking (8 ') that is easily affected by the force (peeling direction A') when peeling the concealment postcard from the upper right side (scheduled opening direction C ') of the concealment postcard. It is preferable that the other end of the opening weakening line (7) is provided. In the case of the configuration shown in FIG. 5B, even if the concealment postcard is opened from both the lower right side (scheduled opening direction C) and the upper right side (scheduled opening direction C ′) of the concealment postcard, It becomes possible to make it easy to form the break line (11) with respect to the paper piece (1).

  Moreover, as shown in FIG. 6, with respect to the end part of the opening weakening line (7), the breaking weakening line (8) described in FIG. 4 and the opening for the opening extending in the opposite direction to the breaking weakening line (8) An auxiliary weakening line (7 ′) may be applied. For example, as shown in FIG. 6 (a), with respect to the end of the opening weakening line (7), the breaking weakening line (8) shown in FIG. 4 (a) and the breaking weakening line (8) In the case of the structure provided with the auxiliary weakening line for opening (7 ') extending in the opposite direction, the postcard paper piece (2) and the masking paper piece (1) are arranged from the lower right side of the masking postcard (scheduled opening direction C). In the case of peeling, the breaking weakening line (8) is easily affected by the force in the peeling direction A, and forms a breaking line (11) with respect to the masking paper piece (1). Irregular opening marks can be left. Conversely, when peeling the postcard piece (2) and the concealment piece (1) from the upper right side of the concealment postcard (opening direction C ′), as shown in FIG. 7) When peeling progresses along the end of the opening weakening line (7), peeling progresses along the auxiliary opening weakening line (7 '), and the opening of the auxiliary opening weakening line (7') When the end is reached, the force (the force in the peeling direction A) is peeled off from the upper right side of the concealment postcard (the opening direction C ′), and the force is applied in the direction of “arrow B” in FIG. It acts and peels away the masking paper piece (1) from the planned opening direction (C ′). Then, the peeling that has been deviated from the planned opening direction (C ′) becomes the receiving portion by the breaking weakening line (8), the peeling proceeds along the breaking weakening line (8), corrects the peeling direction, and opens. When the starting end of the weakening line (7) is reached, peeling proceeds along the opening weakening line (7). That is, the auxiliary opening weakening line (7 ') makes it easier to receive the peeling with the weakening line for breaking (8), and the breaking weakening line (8) corrects the planned opening direction. Thereby, when the concealment postcard is opened from the upper right side (opening planned direction C ′) of the concealment postcard, it is possible to cleanly peel along the opening weakening line (7). For this reason, in the case of the configuration of FIG. 6, when a third party peels off the postcard paper piece (2) and the masking paper piece (1) from the lower right side of the masking postcard (scheduled opening direction C), the masking is performed. Since it becomes possible to leave irregular opening marks on the piece of paper (1) itself, it is possible to recognize whether or not the concealment postcard has been opened by simply looking at the concealment postcard. Further, the recipient side cleans the postcard paper piece (2) and the concealment paper piece (1) from the upper right side of the concealment postcard (scheduled opening direction C ′) along the weakening line for opening (7). Since it can be opened, it is possible to view the contents entered in the entry field (2a) on the inner surface of the postcard paper piece (2) without leaving an opening mark on the masking paper piece (1) itself. .

  Moreover, as shown to Fig.7 (a), with respect to the edge part of the opening weakening line (7), the breaking weakening line (8 ') shown to Fig.5 (a) and its breaking weakening line (8') ) And an auxiliary weakening line for opening (7 ') extending in the opposite direction, the postcard paper piece (2) and the masking paper piece (1) are placed on the upper right side of the masking postcard (opening planned direction C' ), The breaking weakening line (8 ′) is easily affected by the force in the peeling direction A ′, and forms a breaking line (11) with respect to the masking paper piece (1). 1) It becomes possible to leave irregular opening marks in itself. Conversely, when peeling off the postcard piece (2) and the masking paper piece (1) from the lower right side of the masking postcard (scheduled opening direction C), as shown in FIG. The line (7 ′) makes it easier to receive the peeling with the breaking weak line (8), and the breaking weak line (8) corrects the planned opening direction, and the opening weak line (7). Can be opened neatly along. For this reason, in the case of the configuration of FIG. 7A, when a third party peels off the postcard paper piece (2) and the concealment paper piece (1) from the upper right side of the concealment postcard (scheduled opening direction C ′). Since it is possible to leave unseal marks irregularly on the masking paper piece (1) itself, it is possible to recognize whether the masking postcard has been opened or not by simply looking at the masking postcard. Also, the recipient side cleans the postcard paper piece (2) and the concealment paper piece (1) from the lower right side of the concealment postcard (scheduled opening direction C) along the opening weakening line (7).
