Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
159 words
A container means for paints comprising: an optically clear plastic cup-like container; a multi-laminate seal secured to the top of said cup-like container, said seal comprising a first film, a second film continuously joined to said first film, and a third film continuously joined to said second film, said third film forming the outer layer of said seal, said first film and said second film being placed in tension during application to said cup-like container, said third film being applied in a relaxed state to said second film whereby when said multi-laminate seal is slit, said seal will flex inwardly when a brush is inserted therethrough and will return to its original plane when said brush is withdrawn thereby enabling the maintenance of a moisture saturated condition of air above paint contained within said plastic cup-like container; and a top closure member readily attachable and detachable to said cup-like container to provide a further means for protecting container contents.
Claim 2
Dependent Claim
