| 摘要 |
The present invention relates to an improved gravity dispenser for dispensing, inter alia, a concentrate to be mixed with a diluent. The present invention includes a feature for reducing spray caused by closing of a flow control valve. A projection or ridge on a surface of one of the parts of the flow control valve, which projection or ridge can include bevelling or chamfering, sweeps across the area above the dispensing orifice, thereby directing a fluid shock wave away from the dispensing orifice. As a result, the fluid shock wave does not reach the dispensing orifice, thereby reducing or eliminating potential spray through the dispensing orifice.
