The present invention relates to a smart device case.

Recently, various smart devices such as smart phones and tablets are widely used. Since these smart devices are mostly expensive products and are easily damaged, many users are using a case for protecting the smart devices.

As a case for a smart device conventionally introduced, a case to which an epoxy material is applied is exemplified. The case with the epoxy material can prevent scratches on the surface of the smart device, protect the smart device from external impact, apply various printing patterns according to the user's preference, and have good moldability and thin thickness It has various advantages of maintaining the unique design of smart device.

On the other hand, as a means for generating an adhesive force between a case to which an epoxy material is applied and a smart device, a technique of including a silicone adhesive or an acrylic adhesive in a case to which an epoxy material is applied has been introduced. However, the silicone adhesive agent or the acrylic adhesive agent is basically not high in adhesive strength, and may cause a problem that the adhesive agent remains on the surface of the smart device (i.e., transferred) when the adhesive force is excessively increased, Have.

It is an object of the present invention to solve all the problems described above.

The present invention also relates to a smart device comprising a polyurethane pressure-sensitive adhesive layer, a base monolayer formed on the polyurethane pressure-sensitive adhesive layer, and an epoxy layer formed on the base monolayer, It is another object to provide a case for a smart device in which the pressure-sensitive adhesive layer is adhered to the surface of the smart device.

In order to accomplish the above object, a representative structure of the present invention is as follows.

In addition, another smart device case for implementing the present invention is further provided.

According to the present invention, since a polyurethane pressure-sensitive adhesive layer which is superior in adhesiveness and can be reused and can be formed to have a thick thickness of 100 μm or more is used as compared with the conventional acrylic pressure sensitive adhesive or silicone pressure sensitive adhesive, The effect of facilitating the attachment to the smart device (i.e., improving the ease of attachment) is achieved.

In addition, according to the present invention, it is possible to prevent the occurrence of air bubbles or voids between the smart device case and the smart device due to foreign matter such as dust or irregularities (that is, increase the dust responsiveness).

Further, according to the present invention, the effect that the design and logo that the smart device inherently has can be maintained is achieved.
