Description

The present invention relates to a bag having a security function in which when a seal is unsealed, the fact is displayed in an opening, thereby preventing unauthorized opening.

At present, security packaging for preventing theft of important documents, opening / unpacking, and falsification is regarded as important. For this reason, products called security seal labels or security tapes have been developed. As shown in FIG. 8, when attached to an opening of an envelope or cardboard box and peeled off, characters such as “0PEND” and “opened” are transferred and remained in the opening. is there.

Based on the above transcription display, the fact that the opening fact has been checked / detected has been confirmed, and even if it has been opened illegally, the fact remains so that the facts such as removal of the contents, tampering, illegal reading, etc. It is intended to confirm and prevent such criminal acts.

When using a security tape as described above for an envelope, as shown in FIG. 8, after folding the flap along the fold line, it is hung on the flap and the envelope body from above, and the required security tape is applied. Adhere. As a result, when it is opened, characters such as “0PEND” and “opened” remain on the envelope body side, and the fact of opening is confirmed. However, the security tape is normally disabled from reversible attachment at the same time as it is easily confirmed by the misalignment of the transferred residual characters.

Conventionally, the use of security tape for bags, envelopes and the like has been performed as described above.

However, due to its transferability, that is, the peelability of the printed part on the surface, the security tape has a difficulty in its adhesive strength compared to ordinary adhesive tape, and a strong sealing property cannot be expected so much. . Furthermore, when opening after sealing, the character part peelability may change depending on the time, pressure, material, environment, etc. from the time of sealing, which may cause defects in character transfer.

The present invention is intended to provide a new product called a “bag having a security function” that solves the above problems.

In the present invention, as described in claim 1, the existing security tape 3 is attached to the front end of the inner surface of the flap 2, and the security tape 3 is attached to the bag body 1 near the upper edge of the opening. This relates to a bag having a security function in which the belt-like bonding surface 4 is formed.

According to the present invention, the first belt-like bonding surface 5 and the second belt-like bonding surface 6 are arranged in two steps in parallel in the vicinity of the upper edge of the opening of the bag body 1 as described in claim 2. The transfer display portion is used as a security tape 7 that is attached to the front end of the inner surface of the flap 2 and is collectively bonded to both the first and second belt-like bonding surfaces. Alternatively, the present invention relates to a bag having a security function using a material formed close to the lower half side.

As described in claim 3, the present invention uses a security tape 7 that is attached to the inner front end of the flap 2 and has a transfer display portion formed on the upper half side or the lower half side, The present invention relates to a bag having a security function in which a wide belt-like bonding surface that can be superposed on the entire security tape 7 is provided near the upper edge of the opening of the bag body 1.

According to the present invention, instead of the security tape attached to the flap side, the transfer display target portion that functions in the security tape is directly formed on the flap by the printing means. A bag having the security function according to any one of Items 1 to 3 is an embodiment.

Since the present invention adopts the structure as described in claim 1, it is remarkably stronger than a conventional security tape that is attached so as to be hung and sealed on the flap and the envelope body. Stable security tape can be used. That is, the conventional security tape is attached in a sealed shape as shown in FIG. 8, and therefore, it cannot exhibit a strong sealing action, and is also contaminated by the adhesion of dust or the like to the envelope surface. As a result, problems such as flaws in the transfer that should be clear and unexpected peeling occurred.

On the other hand, in the present invention, the security tape 3 is attached to the front end of the inner surface of the flap 2 and is attached to the belt-like adhesive surface 4 attached to the upper edge of the opening of the bag body 1 by polymerization. Therefore, since the security tape itself is not exposed to the outer surface, when opening after sealing like conventional security tape, the character part will be peeled off due to time, pressure, material, environment, etc. from the time of sealing. There will be no change in character and no worries about character transfer.

Further, at the time of sealing, both the adhesiveness of the security tape 3 itself and the adhesiveness of the band-like bonding surface 4 combine to provide a strong sealing action. Based on the force (adhesive force) in the direction in which the surface 4 is left behind, a strong adhesion stabilizing action is applied to the remaining portion for transfer (display portion of characters, etc.), and the clarity and stability of the display is improved. Greatly contributes to securing.

By adopting the configuration as described in claim 2, the present invention exhibits a good transfer display effect and a strong sealing effect. That is, in the case of Claim 1, since it is a system that relies on both transferability and adhesiveness with respect to the security tape, the adhesiveness for sealing is as described above compared to the conventional system. Although it is carried out strongly, there is a peeling part for transfer, so that this peeling may be a negative factor in adhesion.

Therefore, in the invention of claim 2, the first belt-like bonding surface 5 and the second belt-like bonding surface 6 are formed in two stages in parallel. Accordingly, the portion where the transfer portion of the security tape is present and the portion where the transfer portion is absent are polymerized and attached to the separate adhesive surfaces, so that the portion where the transfer portion exists is peeled off for transfer. However, even if the transfer portion does not exist, a uniform adhesive force is ensured over the entire length.

In other words, it is possible to obtain a suitable adhesive force based on the adoption of the two-stage divisional adhesive method, and to obtain a strong sealing force comprehensively. Then, by using the first belt-like adhesive surface 5 and the second belt-like adhesive surface 6 having suitable adhesive strengths, for example, by making the transfer portion have a weak adhesive force, it becomes sensitive to illegal activities. It is possible to make fine adjustments, such as taking measures and allowing the sealed portion to exert a strong adhesive force.

In addition, although it is a point which makes a transcription | transfer part the upper or lower surface for adhesion | attachment, any may be sufficient as this. However, in order to leave a trace by opening the flap a little, it is preferable to form a transfer surface on the lower side. However, the present invention is not limited to this.

The present invention adopts the structure as described in claim 3, that is, as a security tape 7 that is attached to the inner surface near the front end of the flap 2, it is brought close to the upper half side or the lower half side to display for transfer. A belt-shaped bonding surface is formed by using a part formed with a wide band-shaped bonding surface that can be polymerized with the entire security tape, close to the upper edge of the opening of the bag body 1. Since the formation of suffices only once, the speed of manufacturing and the cost of the product can be reduced.

  According to the present invention, by adopting the configuration as described in claim 4, that is, instead of the security tape attached to the flap side, the transfer display target portion that functions in the security tape is made into a flap by the printing means. On the other hand, by forming directly, it is possible to reduce the manufacturing cost and speed up the manufacturing industry.

It is an expanded sectional view showing the use process of 2nd Example same as the above, (A) is the state before sealing, (B) is the sealing state, (C) is the opening state. It is a perspective view showing the 3rd example of the present invention. It is a surface figure showing an example of a security tape. It is a surface view showing an example of a wide security tape. It is a perspective view for explanation showing the example of general use of the conventional security tape.

1 and 2 show a first embodiment of the present invention. In the figure, 1 is a bag body made of paper material or synthetic resin, 2 is a flap of the bag body 1, and the present invention provides a security function to the sealed portion of the bag body 1 and the flap 2. It is characterized by this.

Reference numeral 3 denotes a security tape attached to the front end of the inner surface of the flap 2 by heat welding or glue, etc. The security tape itself has an adhesive action and is “opened” or “0PEND” by peeling off. And the like belong to an existing security tape in which the transfer is left to be transferred. Therefore, the surface has a form with adhesiveness.

4 is a band-like bonding surface formed near the upper edge of the opening of the bag body 1, which is formed by adhering a double-sided tape or applying hot melt so that the surface functions as an adhesive surface. It is configured.

In the state shown in FIG. 2A, the security tape 3 is attached to the belt-like adhesive surface 4 on the bag body 1 side by folding the flap 2 inward as shown in FIG. Wear and keep sealed. And it uses for transportation in this state.

At the time of opening, the flap 2 is peeled off. At this time, the display characters of the security tape 3 are displayed as the remaining transfer portion a on the surface of the belt-like adhesive surface 4 as shown in FIG. Prove that it was opened for the first time. However, if the tampering has been performed in advance, the transfer is duplicated into an improper one and an appropriate one, so that fact is clearly displayed. Of course, when the tampering is opened and the restoration sealing is not performed, the fact of the tampering is made clear based on the fact.

FIG. 3 shows a second embodiment of the present invention. This is because the belt-like adhesive surface formed near the upper edge of the opening of the bag body 1 is a first belt-like adhesive surface 5 and a second belt-like adhesive surface formed by applying double-sided tape or applying hot melt. 6 is configured to be applied in two stages in a parallel state.

In the case of the second embodiment, as the security tape 7 attached to the flap 2 side, a transfer display is formed in the lower half, and the upper half is configured such that there is no transfer display. Use.

Thereby, in the sealed state, for example, the transfer display portion of the security tape 7 is positioned on the lower first strip-shaped adhesive surface 5 portion, and the portion of the security tape 7 without the transfer display is positioned on the upper second strip-shaped adhesive surface 6. Affix with the part positioned. That is, in the second embodiment, sealing and unsealing are performed as shown in FIGS. 4 (a), (b) and (c), but when opened, as shown in FIG. Display is made on the surface of the first belt-like bonding surface 5 as the remaining transfer portion a. The upper second band-like adhesive surface 6 functions exclusively as a sealing adhesive surface, and does not cause the peeling action of the display portion due to transfer, so that the adhesion functions exclusively as a strong sealing adhesive surface.

In other words, the important point in the second embodiment is that it is divided into an adhesive surface for sealing and an adhesive surface for security character transfer. This is because when the character is transferred, the transfer display portion must be peeled off, resulting in a decrease in adhesive strength for sealing. In the second embodiment, a sealing portion that also serves as a transfer and a portion that is exclusively used for sealing are divided so that a strong sealing force can be obtained without deteriorating the transfer action.

In the second embodiment, the belt-like bonding surfaces are formed in two upper and lower rows. However, as in the third embodiment shown in FIG. It can also be configured to be 8. Furthermore, the transfer portion is usually set to the lower first band-like bonding surface 5 side, because this facilitates the transfer confirmation. However, the transfer may be generated on the upper side of the second belt-like bonding surface 6 and the lower side of the first belt-like bonding surface 5 may be used exclusively as a sealing adhesive surface. This is determined depending on whether the display for transferring the security tape is formed on the upper half side or the lower half side. The present invention may be implemented in any of such forms.

Furthermore, the security tape is attached to the flap 2 in the first, second, and third embodiments described above. This is because the print surface (transfer display target portion) having the same function is attached to the flap. It can also be formed directly based on printing means. The present invention may be implemented in such a form.
