Description

The group of inventions relates to a device presented in the form of a plastic keyfob equipped with an integrated RFID tag, and to a method for manufacturing it.

Plastic trinkets equipped with an RFID tag are known in the art.

For example, such as key rings produced by the Chinese company Set (http://www.cetech.com.hk/en_us/products/detail/4).

Trinkets can be of any shape, including rectangular.

The disadvantage of trinkets manufactured by this company is their fragility and unreliability in use due to the fact that the surface layer is usually made of epoxy coating, which is very fragile, and under UV lighting the material turns yellow, due to this the color of the product fades, losing while the primary appearance. In addition, the surface layer of the key fob is made of toxic material, which poses a danger to health and the environment.

A close analogue of the claimed device is described in patent RU 2629143 (priority 07/21/2016).

The plastic keychain is made with full-color printing and equipped with a built-in RFID tag, it is rectangular in shape and has a through circular hole for the ring. The keyfob angles are rounded, and the three keyfob angles have one radius, and the fourth is different from them. The keychain contains sequentially combined layers of a plastic laminate, a decorative information layer on the front side, a central prelaminate with at least one RFID tag installed, a decorative information layer on the back side, a plastic laminate forming together the base, and an adhesive layer is applied on both sides of the base and composite lenses.

A method of manufacturing a plastic keychain consists in first forming a central prelaminate, then forming a multilayer structure - the basis for which, on both sides of the central prelaminate, they are laid on an information-decorative sheet and a protective laminating layer, then all sheets are interconnected using the thermal compression method, from a multilayer design carve many, for example 24, 48, 72 or more, blanks of trinkets with through round holes each, but the trinkets are held on the main ove.

On all preforms, on top of the base, on both sides they are coated with a liquid material based on polyurethane, then the multilayer sheet with the blanks is dried, and the finished key fobs are removed from the base and packaged.

The technical result of the claimed device and method consists in creating a device that performs the function of a key fob and a contactless smart card, as well as increasing its resistance to physical stress that occurs in everyday use, increasing resistance to changes in temperature of the environment of use, to ultraviolet due to the materials used, included in the device, as well as to improve ergonomics and usability of the device.

However, a device from the closest analogue has a significant drawback. Due to the use of a glue layer to connect the base and the composite lens. Attaching a composite lens with glue to smooth surfaces of the base also does not provide the necessary adhesion, and the design as a whole does not have sufficient strength in this case.

In addition, the use of glue complicates the production and increases the cost of the entire structure.

The problem solved by the claimed group of inventions is to increase the structural strength of the key fob and resistance to physical stress in comparison with the closest analogue, reducing its cost, with reducing the time for its manufacture.

The technical result of the claimed device and method is to increase the structural strength of a plastic keychain in comparison with the closest analogue.
