COSMETIC DISPENSER HOUSING AND METHOD |
摘要 |
<p>Doses of cosmetic fluid dispensed from a roll-on dispenser can fluctuate significantly between successive applications. This problem can be alleviated by perturbing flow within the roll-on housing (3), such as air flow, by forming flow perturbators on the interior side-wall (11) of the housing (3). These perturbators can alternatively or additionally comprise lateral beads (20) or notching an interior sealing ring (17). The dispenser housing (3) preferably also includes a spider (4) normally located between the roller and the bottle interior, and preferably a resilient spider (4) having an facing surface parallel with the roller that can control the depth of liquid film adhering to the roller, which when the roller is a ball means a concave upper face of similar radius of curvature to that of the ball.</p> |
