Tamper indicating containers and seals

DETAILED DESCRIPTION The present invention is a seal comprising a substrate preferably being translucent or transparent to light, having an outer surface and an inner surface.
A transparent masking material is disposed in an indicia-defining pattern on the inner surface of the substrate.
The masking material possesses low adhesion properties to the material of said substrate.
A colorant layer is disposed on the inner surface of the substrate over the transparent masking material and can extend beyond the indicia-defining pattern of the masking material.
An adhesive is disposed over at least the area in which the colorant layer and transparent masking material are disposed.
The present invention also includes an opaque container comprising a body portion and at least one integrated sealable closure flap.
The closure flap has an exposed outer surface and a sealable inner surface.
A window portion is defined within an area of at least one outer closure flap.
The window portion registering with a surface of the container upon closure of said flap.
There is a translucent or transparent panel overlaying the window portion and being affixed across at least a portion of its perimeter to a surface of the closure flap.
The panel has an outer surface and an inner surface and possesses surface dimensions greater than those of the window portion such as to define a perimeter portion extending beyond the edges of the window portion.
A transparent masking material is disposed (i) in an indicia-defining pattern (ii) on the inner surface of the translucent or transparent panel opposite the exposed outer surface of said closure flap and (iii) within an area registering with said window portion.
The masking material possesses low adhesion properties to the material of said translucent or transparent panel.
A colorant layer is disposed on the inner surface of the translucent or transparent panel over the transparent masking material and extending beyond the indicia-defining pattern of the masking material.
An adhesive is disposed over at least the area in which said colorant layer and transparent masking material are disposed
