Abstract
Process for the manufacture of methylcellulose capsules, characterized in that said manufacture of the capsules is carried out according to a process comprising the steps of applying a film of an aqueous solution of methylcellulose ether to capsule-forming members, heating above the gelatinization point of said solution, causing the thermogelatinization of the methylcellulose film on said members, and the maintenance of said film and said members at the suitable temperature from the moment of starting the thermogelatinization until the film retains itself the form, the methylcellulose which is used to make these new capsules, is of a type which has a very low intrinsic viscosity, advantageously in the field of 7 to 15 centipoises of intrinsic viscosity, with a methoxyl content of about 30. % and in its dissolution in distilled water at a concentration of one 2%, giving a solution having an intrinsic viscosity around 9 c.p., at 20º c.
