  • Pharmaceutical products
    Patent number: 5888540
    Abstract: A pharmaceutical product in the form of a gelatin capsule with a fill comprises a hydrogel material, a gas generator and an oil-based or hydrophilic based liquid vehicle, wherein upon contact with acidic aqueous medium the gelatin capsule breaks up, disperses or dissolves and the fill reacts to form a foam.
    Type: Grant
    Filed: July 3, 1997

    Inventors: Keith Sugden, Keith Graeme Hutchison
  • Method of making water based beverages
    Patent number: 5871798
    Abstract: A method is disclosed of preparing a beverage in the form of a dilute aqueous solution, suspension or dispersion of an encapsulated product. The capsule is added to a potable liquid, and the capsule material breaks down when submerged in the liquid to release its contents and itself dissolve. A primary advantage of providing the product in this way is that it can be confined within the capsule in liquid form, and can therefore disperse or dissolve in water more readily. Additionally, the capsule would normally sink to the bottom of the body of water before releasing its contents, thereby ensuring that the contents are released within the body of water, and not at the surface thereof.
