PRODUCTION OF SANDWICHED ARTICLE AND SANDWICHED ARTICLE THUS MADE Russian patent published in 2014 - IPC B65D85/00 

FIELD: process engineering.

SUBSTANCE: invention relates to laminar articles based on, for example, cardboard. Laminar article, particularly, sandwiched sensor package comprises at least three plies of paper and/or cardboard, and/or leather, and/or metal, and/or polymer, and/or glass, and/or plastic. Proposed method comprises step-by-step production of liner, its processing by varnishing and/or lamination, and/or embossing, and/or creasing. Mid carcass ply is made from dense cardboard in thickness making at least 3 mm with recesses for wiring the electronic multimedia components. Patterns can be applied to said liner by offset and silk-screen processes, hot embossing, relief stamping or making the raised elements. The article thus produced has the case with built-in display and/or loudspeaker, power supply, control and electronic P.C.B. interconnected in common circuit. Power supply can be composed by storage battery or solar battery. The case outer surface can be equipped with exposed or concealed USB-port connected with electronic p.c.b. and power supply to charging and adding data to electronic p.c.b. memory while control element is composed by sensor of opening, and/or motion transducer and/or control button.

EFFECT: perfected method.
