Document Type and Number:
Japanese Patent JP2004534671
Kind Code:
A
Abstract:
A substance encapsulation system capable of being apertured under a tensioning force comprises a first web and a second web. A powdered, granular, particulate, or gel substance can be disposed between the first and second webs. Upon application of a sufficient force having a vector component parallel to the transverse axis, the bond site fractures to form a corresponding aperture to facilitate exposure of the substance. Alternatively, a central layer may be disposed between at least a portion of the first and second webs. The central layer may carry a substance to be exposed or the central layer may be a dissimilar material from the first and second webs. In a preferred embodiment, the system has a plurality of bond sites.
