A mascara case includes a vial for storing mascara, and a cap mountable on the vial for closing a passage of the vial. The passage is of oblong shape to accommodate insertion and removal of the transverse brush of a T-shaped wand carried by the cap. The cap also carries an oblong sealing ridge engageable with a sealing surface of the vial to surround an inlet of the passage. The cap carries a rotary knob which includes a projection positioned to engage a locking post disposed on the vial, in response to manual rotation of the knob. Engagement between the projection and locking post causes the cap and vial to be drawn together so that the sealing ridge forms an air-tight seal around the vial passage.
