Abstract
The invention relates to a security envelope (20) for an article, the envelope being constituted by a sleeve (21) of heat-shrinkable plastics material that is fitted on its inside face with a holographic element (30) and with a tear strip (22) passing behind said holographic element (30). According to the invention, the holographic element (30) is organized to be transferable onto the facing wall (13) of the article and to adhere to said wall via zones situated on either side of the tear strip (22) so as to hold a portion of said tear strip captive, such that any fraudulent manipulation of the envelope heat-shrunk onto the article has the effect of displacing the tear strip (22) and consequently of automatically and visibly destroying the transferred holographic element (30).
Claims17
A security envelope for an article, in particular a receptacle having a closure device, the envelope being of the type constituted by a sleeve of heat-shrinkable material suitable for closely surrounding a portion of the article, said sleeve being also fitted on its inside face with a holographic element and a tear strip passing behind the holographic element so as to tear said element when the envelope is opened by pulling on said strip, wherein the holographic element is transferable onto the facing wall of the article and can adhere to said wall via adherence zones situated on either side of the tear strip while holding a portion of said tear strip captive, such that any fraudulent manipulation of the envelope once shrunk on the article has the effect of displacing the tear strip and thus visibly destroys the holographic element at said adherence zones thereof.
