Abstract
Abstract A cosmetic sampler has a thin dry layer of discrete fragrance enhanced powder particles removable by light finger pressure as a dry free-flowing powder. The fragrance powder layer is originally applied as a liquid slurry which is dried after application, the individual powder particles being coated and having enhanced fragrance and are readily separable from each other after removal from the substrate to which they have been applied.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
168 words
A fragrance particle sampler, comprising: (a) a substrate having a smooth surface, (b) a layer of readily removable dry adhesively held fragranced powder particles disposed on and lightly adherent to the smooth surface of the substrate, (c) the particles being mixed with a large amount of fragrance oil and surface-coated with a heavy molecular weight oil/wax for sealing in the fragrance and promoting adhesion/cohesion between adjacent particles in the layer binding the particles together, (d) the powder particles being held temporarily in fixed position with respect to each other by the set taken by the coating on the particles binding them together, (e) the coating on the particles and the binding material taking a set within the layer as a residual dried layer after evaporation of the volatile liquid suspension medium originally mixed with the applied layer, whereby the particles lightly adhere to the substrate surface, and on application of light finger pressure are removable therefrom as discrete free-flowing separate particles, having the property of a fragranced powder.
Claim 2
Dependent Claim
168 words
A fragrance particle sampler, comprising: (a) a substrate having a smooth surface, (b) a layer of readily removable dry adhesively held fragranced powder particles disposed on and lightly adherent to the smooth surface of the substrate, (c) the particles being mixed with a large amount of fragrance oil and surface-coated with a heavy molecular weight oil/wax for sealing in the fragrance and promoting adhesion/cohesion between adjacent particles in the layer binding the particles together, (d) the powder particles being held temporarily in fixed position with respect to each other by the set taken by the coating on the particles binding them together, (e) the coating on the particles and the binding material taking a set within the layer as a residual dried layer after evaporation of the volatile liquid suspension medium originally mixed with the applied layer, whereby the particles lightly adhere to the substrate surface, and on application of light finger pressure are removable therefrom as discrete free-flowing separate particles, having the property of a fragranced powder.
Claim 3
Dependent Claim
35 words
The fragranced particle sampler as set forth in claim 1, wherein: (a) the percentage by weight of the binder and oils to the weight of the particles is in the range of 10 to 30%.
Claim 4
Dependent Claim
32 words
The fragranced particle sampler as set forth in claim 1, wherein: (a) the layer contains an emollient substance in the amount of up to 10% by weight of the particles of powder.
Claim 5
Dependent Claim
58 words
The fragranced particle sampler s set forth in claim 1, wherein: (a) the fragrance powder makes up approximately 80% by weight of the overall layer composition, (b) the coating and fragrance oils make up approximately 16% by weight of the overall layer composition, and (c) the binder materials constitute approximately 4% by weight of the overall layer composition.
Claim 6
Dependent Claim
32 words
A fragranced particle sampler as set forth in claim 1, wherein: (a) a coating of a suitable polymeric resin directly beneath the fragranced powder layer to aid in sealing in the fragrance.
Claim 7
Dependent Claim
92 words
A printable liquid ink composition to be applied to a smooth surface substrate, comprising: (a) a fragranced powder having been enhanced by fragrance oil sealed by a high molecular weight oil/wax, the powder being approximately 30 to 50% by weight of the mixture, (b) a liquid volatizing agent constituting by weight of from 40 to 85% of the mixture for providing a liquid suspension medium prior to application of the ink and drying thereof, and (c) binder and emollient material forming by weight from 0.25 to 7% by weight of the mixture.
Claim 8
Dependent Claim
92 words
A printable liquid ink composition to be applied to a smooth surface substrate, comprising: (a) a fragranced powder having been enhanced by fragrance oil sealed by a high molecular weight oil/wax, the powder being approximately 30 to 50% by weight of the mixture, (b) a liquid volatizing agent constituting by weight of from 40 to 85% of the mixture for providing a liquid suspension medium prior to application of the ink and drying thereof, and (c) binder and emollient material forming by weight from 0.25 to 7% by weight of the mixture.
Claim 9
Dependent Claim
27 words
The fragrance particle sampler of claim 1, wherein: (a) the adhesion/cohesion promoting substance is selected from the group consisting of fatty esters, fatty alcohol, and fatty acids.
Claim 10
Dependent Claim
39 words
The fragrance particle sampler of claim 1, wherein: (a) the discrete free-flowing separate particles are equivalent in size when removed from the substrate surface by light finger pressure as they were prior to being mixed with the binding material.
Claim 11
Independent Claim
126 words
The method of producing a thin, flat fragrance sampler having a thin removable dry powder layer, comprising the steps of: (a) coating a fragrance powder with a high molecular weight sealing oil/wax constituting a percentage by weight which is very substantially less than that of the fragranced powder, (b) mixing the coated fragrance powder with a liquid volatizing agent which constitutes a greater percent by weight of the mixture than the weight of the coated powder, (c) applying the mixture in volatile liquid form to form a substrate having a coated surface, and (d) drying the fragranced powder layer applied to the substrate to obtain a dry readily removable layer of discrete fragrance powder particles equivalent in size to the fragrance powder particles prior to coating.
Claim 12
Independent Claim
