  • Patent number: 8377470
    Abstract: A non-gelatin encapsulation system for liquid filled soft capsules, by nature of the carrier, the cationic-ionic balance of the carrier and the active ingredients, or the concentration of the active ingredients and excipients, are difficult or impossible to commercially encapsulate in gelatin capsules. In particular, the system is adapted for the encapsulation of highly basic, or alkaline, fills. The system provides for a predominantly starch and gelling carrageenan based shell, which displays high resistance to both concentrated fills and to alkaline fills, in particular, to those fills which contain the salt or salts of weak acids and strong bases.
    Type: Grant

  • Patent number: 6099858
    Abstract: Methods for preparing soft gelatin capsules containing fragrances are disclosed. The desired fragrance is dissolved in a solvent system comprising a volatile solvent, a non-volatile cosolvent, or a combination of a volatile solvent and a non-volatile cosolvent or cosolvents. The resulting mixture is then encapsulated between gelatin ribbions prepared with an odor-free gelatin plasticized with a partially dehydrated, hydrogenated glucose syrup.

  • Patent number: 5735105
    Abstract: A continuous solvent free gelatin encapsulation apparatus and process includes an oil roll back assembly (20) for applying a controlled amount of a food-approved lubricant to a first side of the gelatin ribbon and an applicator guide bar assembly (40) for applying a controlled amount of food-approved lubricant to a second side of the gelatin ribbon. Two opposing food-approved lubricant coated gelatin ribbons are then united in a die assembly (50) to form gelatin capsules which are then dried and recovered.

  • Patent number: 5670159
    Abstract: Fragrances in soft gelatin capsules are disclosed. The desired fragrance is dissolved in a solvent system comprising a volatile solvent, a non-volatile cosolvent, or a combination of a volatile solvent and a non-volatile cosolvent or cosolvents. The resulting solution is then encapsulated by soft gelatin shell prepared with an odor-free, glycerol free gelatin plasticized with a partially dehydrated, hydrogenated glucose syrup.

  • Patent number: 5614217
    Abstract: A gelatin capsule that is generally resistant to humidity having a non-hygroscopic plasticizer and an elasticity reducing gelatin extender in the formulation of the gelatin capsule shell. The capsule is capable of being manufactured on conventional rotary die encapsulation devices and can readily hold liquid fill materials. The capsule is breakable with manual pressure.

  • Patent number: 5484598
    Abstract: Knurled surfaces such as raised ribs are provided on the shell of a soft gelatin capsule in order to enhance gripping and manipulation of the capsule. The capsule has a removable tab at one end thereof which may also be provided with a knurled surface. One embodiment of the invention is a capsule used for delivery of medicaments to an external body surface. An alternative embodiment of the capsule is disclosed for insertion into a body orifice. The composition of the capsule includes a starch or starch derivative which gives the capsule a drier feel and increases the coefficient of friction of the surface of the shell, further improving the capsule's handling characteristics.
