Patent number: 5535885Abstract: The invention is a fragrance sample container comprised of a central cosmetic-containing portion substantially surrounded by a peripheral portion having thickened edges. The entire container is preferably made of soft-gelatin. The thickened edges of the peripheral portion, made of solid gelatin, serve to distribute and absorb the planar force of a weight applied to the container, in order to prevent the central cosmetic-containing portion from rupturing under the pressure of the weight. The invention is particularly useful in the distribution to potential customers of sample unit doses of fragrances or other cosmetics through the mails or in magazines.Type: GrantFiled: March 15, 1994Date of Patent: July 16, 1996Assignee: R.P.

Patent number: 5378827Abstract: A process for the production of cellulose carbamate from cellulose and urea through the conversion of the cellulose with excess urea in an inert liquid organic reaction carrier at a temperature in the range of 130 .degree. to 160.degree. C., separation of the reaction carrier from the reaction mixture and washing of the reaction mixture with water. The cellulose is intimately mixed with an aqueous urea solution. Then the water in the solution is replaced with the organic reaction carrier, and the reaction of urea and cellulose is carried out in the presence of an inert gaseous carrier to remove the by-product ammonia. Thereafter, the organic reaction carrier remaining in the reaction product is replaced with an aqueous urea solution and the resulting suspension of cellulose carbamate in the urea solution is filtered and washed free of urea with water. No liquid ammonia is required in this process.Type: GrantFiled: September 16, 1993Date of Patent: January 3, 1995Assignee: Zimmer AktiengesellschaftInventors: Gerhard Keunecke, Adolf Arnold, Sabine Butzke
