Abstract
According to this process for inclusion of a thin electronic label (1) with a flat face, at a predetermined depth in the wall of a molded item made of plastic material (15) at a predetermined temperature and pressure, the flat face of the label (1) is first attached to a support (5) made of a plastic material, with a thickness essentially equal to the desired inclusion depth, the support (5) is attached to the wall (13) of the mold, then the plastic molding material (15) is brought into the mold (13, 14) at said pressure and temperature so that an intimate bond is formed by melting in the region of contact (8, 9, 10, 16) between the two plastic materials at the time of molding.
Claims16
A process for including a thin electronic label with a flat face, at a predetermined depth in a wall of a molded object made of plastic material at predetermined temperature and pressure, comprising:
- providing a support made of plastic material having a first side, a second side and a thickness essentially equal to the desired inclusion depth;
- attaching the flat face of said electronic label to the first side of said support by directly adhering the flat face of said label to the first side of said support;
- fixing the second side of the support to the wall of the mold;
- then
- introducing the plastic molding material into the mold at said pressure and temperature, wherein said plastic molding material directly contacts said electronic label;
- said plastic label support having a composition and thickness capable of both supporting said electronic label and forming an autogenous weld with said plastic molding material in the contact region between the support and the molding material at the time of molding.
A preparatory device for inclusion of a thin electronic label with a flat face, at a predetermined depth in the wall of a plastic molded item made from plastic molding material at a predetermined temperature and pressure and at a selectable location relative to the wall of a mold for said molded item, said preparatory device comprising said electronic label, and a support made of plastic material having a first side, a second side and a thickness essentially equal to the desired inclusion depth;
- the first side of said support being adhered to the flat face of said label, the second side of said support having a relatively weak adhesive adapted to removeably adhere said preparatory device to the wall of said mold;
- wherein said plastic label support has a composition and thickness capable of both supporting said electronic label and forming an autogenous weld with said plastic molding material in the contact region between the support and the molding material at the time of molding;
- wherein said electronic label includes an electrical circuit forming an antenna printed on an insulating substratum and connected to an integrated circuit having a memory;
- and
- wherein said electronic label is adapted to directly contact said molding material.
