The methods can include thermoforming the polymer composition in a mold, or injection molding the polymer composition in a molten form in a mold.

TRANSPARENT CONDUCTIVE SUBSTRATE STRUCTURE USED FOR THERMOFORMING PROCESS

A transparent conductive substrate structure used for a thermoforming process includes a transparent cover plate and a touch sensing layer structure. The transparent cover plate includes a toughening layer on one side thereof. The touch sensing layer structure arranged on one surface of the toughening layer, and includes a first transparent conductive layer, a dielectric layer, a barrier layer, a second transparent conductive layer, and a buffer protective layer. Each transparent conductive layer is directly applied to the transparent cover plate, so that the thickness between the transparent conductive layers is below 1 μm. The thickness between layers may be reduced to increase the sensitivity of the touch sensing layer structure. To prevent each transparent conductive layer and an electrode wire layer from breaking during the thermoforming process, the transparent conductive substrate structure is combined with the buffer protective layer to strengthen the structure of each transparent conductive layer.

Tamper evident plastic food container
11479389 · 2022-10-25 · ·

The tamper evident container includes a base with a base hinge panel and a lid with a lid hinge panel. A hinge connects the panels. A frangible line extends from an edge of the lid hinge panel to a first point on the panel and then outwardly to the hinge. The frangible line crosses the hinge and extends inwardly to a second point on the base hinge panel. From the second point the frangible line extends to an edge of the base hinge panel. When the container is initially sealed, the frangible line separates upon the application of an upwardly directed force to a first portion of the lid hinge panel while a second portion of the lid hinge panel is held in a fixed position or moved downwardly. The separation of the frangible line creates two grasping portions that can be used to pull the lid from the base.
