Container seal with integral promotional token and method
View Patent ↗A container seal having a releasable, integral promotional token attached thereto comprises a sealing sheet bound to a promotional token by a releasable adhesive. The sealant sheet has a tacking surface and a sealing surface. The promotional token has a tacking surface and an obverse surface. At least one surface of the promotional token has promotional indicia visible thereon. The tacking surface of the promotional token is bound to the tacking surface of the sealant sheet by a releasable adhesive, so that the promotional token is peelably removable from the sealant sheet when the sealant sheet is bound to the finish of a container. In a preferred embodiment, the obverse surface of the promotional token is bound to a compressible liner by a second layer of releasable adhesive, the liner being separable from the promotional token without separating the promotional token from the sealing sheet. Preferably, the promotional indicia are in the form of a redeemable coupon, a proof-of-purchase indicator, or a game token.
1. A container seal having a releasable, integral promotional token, the container seal comprising:
