Patent number: 9198833Abstract: The invention relates to a device for oral application of a composition. The device comprises recess having an outer rim encompassing the recess. Within the recess, a composition is arranged. The composition comprises a gelling agent and an active agent. A cover member is attached to the rim and completely covers the recess. Thus, the cover member, together with the recess, retains the composition within the recess. The cover member has an outer surface opposed to an inner surface adjoining the recess. In order to allow preparation of the composition by adding water without the risk of losing some of the composition during preparation, the cover member comprises one or more openings for providing fluidic connection between the inner surface and the outer surface. Through this opening, water can enter for preparing the composition meanwhile the cover retains all composition within the recess. The invention further relates to a method for manufacturing the device.Type: GrantFiled: January 15, 2010Date of Patent: December 1, 2015Assignee: SANDOZ AGInventors: Franz Xaver Schwarz, Szabolcs Szerdi
