Abstract
A dispenser package for fluent products such as cosmetics and lotions that includes an integrally molded plastic container having a flexible body with a sidewall, a closed bottom, and a top wall having a dispensing opening offset from the axis of the container body. A closure has a base wall and a peripheral skirt. In some embodiments of the invention, the closure is rotatably mounted on the container body, and has a dispensing opening in the closure base wall for selective registry with the dispensing opening in the top wall of the container body. Detent elements are provided on the closure and container body for selectively locking the closure in open and closed positions. In alternative embodiments, the closure includes a flip-top hinged to the base wall, with a plug extending therefrom for selectively opening and closing the dispensing opening in the container body top wall.
