Document Type and Number:
WIPO Patent Application WO2006041701
Kind Code:
A3
Abstract:
A dispenser has a barrel (12) which is closed at one end by a base and has a plurality of apertures (28) at the other end through which a viscous material such as a gel or lotion is dispensed. A thermoplastic seal unit (30) closes the plurality of apertures. The seal unit is comprised of an elongated section with a plurality of projections (32) depending from the substantially planar section, the plurality of projections aligned with and closing the plurality of apertures. The seal unit can be removable and usually not replaceable after each use of the dispenser. The thermoplastic seal unit, which preferably is a thermoplastic elastomer, is molded onto the top surface of the barrel after the barrel top surface has been formed. It is molded into the apertures to thereby close the apertures. The seal unit can have pull tabs for the easy removal of the seal unit. This seal unit provides a positive seal for the lotion or gel substance that is to be dispensed from the barrel.
