摘要:
A dispenser for dispensing a substance, such as a liquid lipstick or other cosmetic, pharmaceutical or cosmeceutical product, has a body with a variable-volume storage chamber for storing the product. A dispensing portion is connected with the body and a one-way valve for dispensing amounts of product therethrough. The dispensing portion defines a compression chamber in fluid communication with the storage chamber for receiving product therefrom, and an outlet aperture coupled in fluid communication with the compression chamber. The one-way valve has a valve seat, and a visco-elastic valve cover seated on the valve seat and defining a normally-closed, axially-extending seam therebetween forming a fluid-tight seal between the valve cover and valve seat. The flexible valve cover is movable relative to the valve seat, and the seam is connectable in fluid communication with the outlet aperture to allow the passage of product through the seam and out of the dispenser. An actuator is drivingly connected to the compression chamber for pressurizing product within the compression chamber and dispensing an amount of product within the compression chamber.

A device for storing and dispensing a substance includes a container having a body defining therein a storage chamber for receiving and storing the substance. The container includes a head located at one end of the body and a first passageway that is in fluid communication with the storage chamber of the body and defines a flow path therebetween. The container also includes a pierceable wall located on an opposite side of the passageway relative to the storage chamber, and a first connecting portion for connecting another component thereto. The device also includes a one-way valve assembly that includes a valve body including a body base defining a second passageway and at least one piercing portion engageable with the pierceable wall of the container. The valve assembly includes a second connecting portion that is connectable to the first connecting portion of the container for fixedly securing the valve assembly to the container when the valve assembly and container are located in the second position. The valve assembly includes a valve seat and at least one flow aperture extending through the valve body adjacent to the valve seat and in fluid communication with the second passageway for receiving the substance from the storage chamber therethrough.
