Description

  The present invention relates to a sheet for preventing shoplifting that can be recycled.

  Usually, in various stores that rent and sell books, CDs (compact discs), etc., products are arranged on display shelves, and customers pick up these products and select and purchase them.

On the other hand, shoplifting has been rampant in recent years, and various shoplifting measures have been taken because various stores have suffered great damage. As a measure against shoplifting, for example, a security camera is installed in the store, or a self-sounding tag described in Patent Document 1 is pasted on each display product, and the tag is peeled off or the product is attached to the store while holding the tag. Crime prevention measures such as a buzzer sounding a warning when going outside are taken.

  However, for example, in a CD, a tag is usually attached to a CD case. However, a clever technique for taking out only the contents CD and shoplifting is increasing. In order to solve such problems, a method for directly attaching a tag to a CD has been proposed. However, once a tag is directly attached to a CD, it is difficult to remove the tag, and even if the tag is removed, the label surface of the CD There are problems such as scratches and loss of value as a product. For this reason, if the adhesive strength for attaching the tag is weakened, the tag is peeled off by a shoplifter, and shoplifting cannot be prevented.

  Further, when the tag is directly attached to the CD, there is a problem that the sensitivity of the tag becomes dull and the buzzer does not sound without reacting to the security gate. Furthermore, there is a problem that sound quality deteriorates (halation) when a CD with a tag attached is directly inserted into a player to listen to music.

  This invention is made | formed in view of the above situations, and this invention aims at providing the sheet | seat for crime prevention which improved the above problems.

  An object of the present invention is to provide a crime prevention sheet that can effectively prevent shoplifting. The present invention is a crime prevention sheet that is directly attached to a product, in which a tag is attached to the product. This is effectively achieved by sticking the material through an adhesive.

  The object of the present invention is that the substrate is polyvinyl chloride, the substrate is paper, or the adhesive is an acrylic adhesive, or The adhesive strength of the adhesive against SUS is more effectively achieved by being 2 to 6 N / cm, or the product being a CD or a book.

  According to the crime prevention sheet of the present invention, it has been found that even if it is directly attached to a CD, for example, music can be listened to as it is and the sound quality is not deteriorated. Thereby, shoplifting can be effectively prevented. Further, since the base material is provided between the CD and the tag, the sensitivity of the tag is dull and it does not react to the crime prevention gate, and shoplifting can be prevented more effectively. Furthermore, since the crime prevention sheet of the present invention can be easily peeled off by using an organic solvent, it can be recycled without damaging the CD. As a result, the damage caused by shoplifting has been reduced, and the budgeting of various stores for shoplifting can be reduced.

  Hereinafter, the present invention will be described in detail with reference to the drawings. For convenience of explanation, a case where the product to which the security sheet of the present invention is attached is a CD will be described.

  The present invention is characterized in that music can be listened to as it is without reducing the sensitivity of the tag even if it is directly attached to the label surface of a CD. Further, by using an organic solvent, the security sheet of the present invention can be easily peeled off from the CD, and can be recycled.

  FIG. 1 is a cross-sectional view showing a state in which the security sheet of the present invention is used. A substrate 3 is stuck on the label surface of the CD 1 via an adhesive layer 2. A tag 4 serving as a security sensor is affixed on the base material 3.

  The adhesive layer 2 plays a role of attaching the label surface of the CD 1 and the substrate 3. As the pressure-sensitive adhesive used in the present invention, it is preferable to use acrylic, ester-based, urethane-based pressure-sensitive adhesives, water-soluble emulsion pressure-sensitive adhesives, etc., and a plurality of these may be used in combination. Moreover, the adhesive which can be peeled again can also be used. In addition, it is preferable to use an acrylic adhesive from the viewpoint of excellent heat resistance, cost, and adhesive strength.

  The adhesive strength of the adhesive layer 2 against SUS is preferably 2 to 6 N / cm. When the adhesive strength against SUS is less than 2 N / cm, the security sheet of the present invention can be easily peeled from the CD 1 and it is difficult to prevent shoplifting. On the other hand, if the adhesive strength against SUS is larger than 6 N / cm, the security sheet of the present invention cannot be peeled from CD1, and CD1 cannot be recycled.

  By sticking the base material 3 between the label surface of the CD 1 and the tag 4, the problem that the sensitivity of the tag 4 becomes dull and the buzzer does not sound can be prevented. Further, even when the CD 1 is inserted into the CD player and the music is listened with the tag 4 attached, the sound quality is prevented from deteriorating. The material of the base material 3 is, for example, known various substances such as polyvinyl chloride, polyethylene, ethylene-vinyl acetate copolymer, (meth) acrylic acid ester copolymer, paper, non-woven fabric, acrylic rubber sheet, These may be used alone or in combination. In the present invention, it is preferable to use polyvinyl chloride from the viewpoint of cost.

  The tag 4 is attached on the base material 3, and the attachment method can take various known methods such as a method of attaching with an adhesive material. As the tag 4 used in the present invention, various known tags such as a sensor tag corresponding to radio waves and a sensor tag using magnetism can be used.

  If, for example, a publisher name, CD name, author name, destination information, etc. are written on the tag 4 by attaching a barcode or the like, product management can be performed simultaneously.

  The crime prevention sheet of the present invention can easily peel off the CD 1 and the substrate 3 by using an organic solvent such as hexane or cyclohexane. For this reason, since the sheet for crime prevention can be peeled off without damaging the CD 1 as in the prior art, the CD 1 can be recycled.

  As mentioned above, although the crime prevention sheet | seat of this invention was demonstrated in detail, this invention is not limited to these. For example, products that can use the security sheet of the present invention are not limited to CDs, and can be used for books, for example. When the security sheet of the present invention is used for a book, it can be installed in various places such as the cover of the book. As described above, for example, if a book classification code or the like is written in the tag 4, an arrangement (display) work in a large bookstore, a library, or the like is facilitated.

It is sectional drawing which showed the state which used the sheet | seat for crime prevention of this invention for CD.
