US Patent 7527844 Wrapping provided with an inside coupon

A wrapping is formed around at least one pack by wrapping film, and the pack has a receiving face against which a coupon is placed. The coupon is also positioned against an inner surface of the film between the pack and the film. Opening of the wrapping film is achieved by a tear strip which separates the film into two portions and which is situated, before tearing, disposed between the coupon and the film. The wrapping is characterized in that the coupon is fixed locally against the inner face of the film in such a way that, after opening of the film by the tear strip, the coupon remains attached to a single one of the first portion of the film, the second portion of film and the tear strip of the film.
