Patent number: 7464519Abstract: A process for the production of water-soluble pouches. The process comprises the steps of drawing a first film into a mould to form a first compartment, adding composition to the first compartment, drawing a second film into the mould to form a second compartment which comprises a composition and, preferably, sealing. The first film is perforated and the second film is drawn into the mould by means of suction applied through the first film. This eliminates the need to align separately formed pouches or containers. This also reduces the total amount of film needed to produce a multi-compartment pouch. Furthermore, it is very easy to vary the film material used according to what properties are desired. Since the different compartments may require different properties this adds flexibility to the process. Process particularly suited for the production of water soluble pouches such as cleaning or fabric care pouches.Type: GrantFiled: December 21, 2005Date of Patent: December 16, 2008Assignee: The Procter & Gamble CompanyInventors: Wayne Robert Fisher, Gregory Martin Gressel

Publication number: 20020123444Abstract: The present invention relates to a container comprising one or more sheets of pouches which are water-soluble, typically the sheet as a whole being water-soluble, the pouches comprising compositions to be delivered to water, typically cleaning compositions and/or fabric enhancing compositions. This provides an easy, efficient and cheap way to pack the pouches in orderly manner and moreover, by immobilizing the pouches in this manner, the pouches are protected against physical forces, without the need of expensive, complex packaging to protect the pouches.Type: ApplicationFiled: November 14, 2001Publication date: September 5, 2002Inventors: Wayne Robert Fisher, Gregory Martin Gressel
