Abstract
The present invention is a spray dispenser device for receiving, puncturing and spray dispensing liquid from a sealed container. It includes an upper housing having a top, bottom, side walls, top opening, bottom opening and a vertical central axis of rotation. The top opening is for receiving and holding a spray mechanism, e.g. a pump, and the bottom opening is for a dip tube and piercing element. A lower housing is rotatably connected to and below the upper housing. It has a top, a bottom and side walls and has at least one top orifice. It is adapted to receive a container having a puncturable top seal. A container is placed within the bottom of the lower housing; the upper housing and lower housing are rotated relative to one another from a first position wherein the dip tube and piercing element are located away from the bottom of the lower housing, to a second position wherein they are closer to the bottom of the lower housing, the piercing element punctures the puncturable top seal and the dip tube enters the container through the puncture, for subsequent spray dispensing therefrom.
