  • Patent number: 6656303
    Abstract: A process for producing a sheet for sustained release of a volatile drug, characterized by dissolving a resin serving as an adhesive in a volatile drug and using the resultant solution as a coating fluid to bond a film permeable to the volatile drug to another film permeable or impermeable to the volatile drug. No organic solvent or peeling film for process is used, accordingly, unlike the so far known process. Consequently, it is not necessary to provide the drying step for removing an organic solvent as well as any thermal energy. As a result, the number of production steps can be reduced considerably. In addition, since the volatile drug is homogeneously diluted in the adhesive, the volatile drug can be incorporated accurately and evenly even in an amount as small as 1 g/m2 or less. According to the process of the invention, a thinner layer containing a volatile drug can be formed.

  • Patent number: 6511562
    Abstract: A bonding strip that functions as a carrier for a load bearing fabric. The bonding strip includes a pair of bonding strip halves that sandwich the fabric. The bonding strip halves are intersecured by an adhesive that extends through and is intimately interconnected with the fabric. The bonding strip halves each define at least one bonding groove. The adhesive extends into the bonding grooves to mechanically interconnect the adhesive, the bonding strip halves and the fabric.
