A process for making the capsule of claim 56, wherein the process comprises filling a first envelope mass through a first nozzle into a mold,pressing a chilled shaped body into the first envelope mass in the mold,shaping and cooling the first envelope mass,introducing a filling mass through a second nozzle,applying a second envelope mass through a third nozzle to form an envelope, where the first and third nozzles and the and first and second envelope masses may be identical,sealing the formed envelope and removing a finished capsule from the mold.

77. A process for making the capsule of claim 56, wherein the process comprises forming a mold from an upper half-mold and a lower half-mold, where the upper half-mold has an opening,inserting into the mold, through the opening in the upper half-mold, a twin nozzle which comprises an inner channel concentrically arranged in an outer channel,feeding envelope mass through the outer channel into the mold to form a continuous base of envelope mass,feeding filling mass through the inner channel into the mold, where during the feeding of the envelope mass and the filling mass the nozzle is moved upward out of the mold,stopping the feeding of the filling mass to allow forming of a sealed envelope,separating the two half-molds from one another to release a finished capsule.

78. A process for making the capsule of claim 56, wherein the process comprises providing a half-mold having an open upper surface or an upper opening;inserting into the half-mold, through the open surface or the opening, a twin nozzle which comprises an inner channel concentrically arranged in an outer channel,feeding envelope mass through the outer channel into the half-mold to form a continuous base of envelope mass,feeding a filling mass through the inner channel into the half-mold, where during the feeding of the envelope mass and the filling mass the nozzle is moved upward out of the half-mold,stopping the feeding of the filling mass to allow forming of a sealed envelope,releasing a finished capsule from the half-mold.

79. A method of applying at least one of a cosmetic ingredient and a dermatological ingredient to skin, wherein the method comprises at least one of rubbing and distributing on the skin a capsule of claim 38 which comprises the at least one of a cosmetic ingredient and a dermatological ingredient.

80. The method of claim 79, wherein the at least one of a cosmetic ingredient and a dermatological ingredient is comprised in the envelope.

81. The method of claim 79, wherein the capsule comprises a filling and the at least one of a cosmetic ingredient and a dermatological ingredient is comprised in at least one of the envelope and the filling.

82. The method of claim 80, wherein the at least one of a cosmetic ingredient and a dermatological ingredient is comprised in at least the filling.
