Claim 1
Independent Claim
109 words
A multilayered structure for sampling cosmetic compositions containing at least 5% by weight of emollients or waxes, said structure comprising a carrier sheet, a window sheet and a cover sheet, said carrier sheet having a portion of at least one surface thereof with a coating of said cosmetic composition thereon, said window sheet having a hole therein which exposes at least a portion of said coating of cosmetic composition, and said cover sheet covering said hole in said window sheet wherein said carrier sheet, window sheet and cover sheet are portions of the same sheet formed by two folds of said same sheet to form a Z cross section.
Claim 2
Dependent Claim
109 words
A multilayered structure for sampling cosmetic compositions containing at least 5% by weight of emollients or waxes, said structure comprising a carrier sheet, a window sheet and a cover sheet, said carrier sheet having a portion of at least one surface thereof with a coating of said cosmetic composition thereon, said window sheet having a hole therein which exposes at least a portion of said coating of cosmetic composition, and said cover sheet covering said hole in said window sheet wherein said carrier sheet, window sheet and cover sheet are portions of the same sheet formed by two folds of said same sheet to form a Z cross section.
