Patent

CA 2143332

A container system is provided for a liquid which has a viscosity below 1000 mPas. The container system comprises a dis- charge orifice (13) which is sealed by a retractive self seal valve (3). In particular, the invention relates to a standing plastic bottle (1) for dishwashing liquids having a retractive self sealing valve (3) over its disharge orifice (13). When squeezing the bottle (1) to discharge liquid the retractive self sealing valve (3) pops out first (fig. b) before a slit (25) in the top portion of the self sealing valve (3) opens to squirt out liquid (fig. c). Upon releasing pressure from the bottle (1) the slit (25) closes and the valve (3) retracts (fig. a). This provides improved separation between the liquid and the bottle cap such that a less messy discharging operation is achieved.
