Abstract
A process for making a water-soluble detergent pouch containing a solid component is provided, where the process employs a scraper and a vacuum. The process includes deforming a first water-soluble film into a cavity and over a surrounding edge to form an open recess and a film-covered surrounding edge, filling the open recess with a solid component, passing a scraper over the top of the filled recess to remove some of the solid component, applying a vacuum to remove some of the solid component, and positioning a second water-soluble film to close the filled recess by sealing the second water-soluble film to the first water-soluble film.
Claims15
A process for making a water-soluble detergent pouch, the process comprising the steps of:
- (a) placing a first water-soluble film over a mold having a cavity and a surrounding edge;
- (b) deforming the first water-soluble film into the cavity and over the surrounding edge to form an open recess and a film-covered surrounding edge;
- (c) filling the open recess with a solid component of a detergent composition to form a filled recess, wherein some of the solid component also spills onto the film-covered surrounding edge;
- (d) passing a scraper over a top of the filled recess and a top of the film-covered surrounding edge to remove some of the solid component from the film-covered surrounding edge to form a scraped film-covered surrounding edge, wherein the first water-soluble film is free from contact with any scraper during the process;
- (e) applying a vacuum to the scraped film-covered surrounding edge to remove some of the solid component from the scraped film-covered surrounding edge to form a vacuumed film-covered surrounding edge;
- and
- (f) positioning a second water-soluble film over the filled recess and vacuumed film-covered surround edge, and closing the filled recess by sealing the second water-soluble film to the first water-soluble film present in the vacuumed film-covered surrounding edge, to form the water-soluble detergent pouch,
- wherein the water-soluble detergent pouch comprises the detergent composition having the solid component that is enclosed by the first water-soluble film and the second water-soluble film.
