ABSTRACT:
A container and dispenser for adhesives and sealants such as silicon rubber is disclosed. The device comprises a thin-walled tubular member formed of plastic or other material which is non-permeable to air or water vapor. The tubular member has a typical diameter in the range of 1/8 to 1/2 inch. The tubular member is open at each end thereof. The portion of the sealant adjacent each open cures from its exposure to the air, forming a seal or plug at each end of the tubular member. The sealant or adhesive is dispensed by cutting open the tubular member in the area intermediate the sealed ends, and squeezing the tubular member. Any unused portion will seal itself for later use.
