Abstract
A seal for use with a container for storing and dispensing consumer products is described. The seal includes a cover layer having pre-formed lines of separation defining one or more releasable portions, an adhesive layer on the cover layer, and one or more patches on the adhesive layer. Each patch is associated with a respective one of the releasable portions 6 and consists of a hot melt polymer. The hot melt polymer can be applied to the adhesive layer using a suitable coating or spraying process.
Claims6
A multi-layer product comprising:
- a first layer having pre-formed lines of separation defining one or more first portions;
- an adhesive layer on the first layer;
- one or more patches on the adhesive layer, each patch being associated with a respective one of the one or more first portions, consisting of a hot melt polymer, and providing moisture-barrier properties;
- a second layer;
- and
- a release layer on the second layer and between the second layer and the adhesive layer including the one or more patches thereon, wherein
- the adhesive layer includes one or more areas with the one or more patches thereon, and one or more areas that are free of patches,
- for the one or more areas of the adhesive layer that include the one or more patches thereon, the multi-layer product consists of five layers, and
- for the one or more areas of the adhesive layer that are free of patches, the multi-layer product consists of four layers.

A multi-layer product comprising:
- a first layer having pre-formed lines of separation defining one or more first portions;
- an adhesive layer on the first layer;
- one or more patches on the adhesive layer, each patch being associated with a respective one of the one or more first portions, consisting of a hot melt polymer, and providing moisture-barrier properties;
- a second layer;
- and
- a release layer;
- wherein
- the one or more first portions comprises an array of first portions, the one or more patches comprises an array of patches, the adhesive layer including the array of patches applied thereon comprises areas of the adhesive layer covered by the patches and areas of the adhesive layer that surround the patches and are not covered by the patches,
- the release layer is disposed on the second layer and between the second layer and the adhesive layer including the array of patches applied thereon,
- the release layer covers and contacts the patches in the areas of the adhesive layer covered by the patches,
- the release layer covers and contacts the areas of the adhesive layer that surround the patches and are not covered by the patches,
- for the one or more areas of the adhesive layer covered by the patches, the multi-layer product consists of five layers, and
- for the one or more areas of the adhesive layer that are not covered by the patches, the multi-layer product consists of four layers, and
- the second layer is configured to be peeled away, with the release layer, to expose the adhesive layer and the array of patches, thus enabling the first layer including the array of patches to be adhered to a generally planar surface at the areas of the adhesive layer that surround the patches and are not covered by the patches.
