Atomizer with a bellows-shaped container body
First Claim
Patent Images
1. An atomizer for containing a liquid, said atomizer comprising:
- a flexible container body including a bellows-shaped surrounding wall having a plurality of foldable layers, a top end, and a bottom end, a bottom wall having an outer periphery that is formed integrally with said bottom end of said surrounding wall so as to define a closed bottom end of said container body, a liquid-containing chamber defined within said surrounding wall and above said bottom wall and adapted to be filled with the liquid, and a mounting member disposed on said top end of said surrounding wall; and
a nozzle head unit attached to said mounting member of said container body and adapted to be operated to discharge the liquid from said chamber therethrough in such a manner that said foldable layers are folded from said bottom end of said surrounding wall to said top end of said surrounding wall;
wherein said foldable layers of said surrounding wall cooperatively define a helical slot in an outer surface of said surrounding wall, and wherein said bottom wall includes an outwardly and upwardly inclined top surface which has a central portion that is formed with a groove, and which is adapted to guide the liquid to flow inward on said inclined top surface and into said groove, said nozzle head unit including a vertical straw that is disposed within said chamber and that is aligned with said groove such that a lower end of said straw can move into said groove when said surrounding wall contracts, said lower end of said straw being disposed adjacent to a lower end of said groove when said surrounding wall contracts completely.

Abstract
An atomizer includes a flexible container body and a nozzle head unit. The container body includes a bellows-shaped surrounding wall, a bottom wall having an outer periphery that is formed integrally with a bottom end of the surrounding wall so as to define a closed bottom end of the container body, and a liquid-containing chamber defined within the surrounding wall and above the bottom wall and adapted to be filled with liquid. The nozzle head unit is attached to a top end of the surrounding wall, and can be operated so as to contract the container body, thereby discharging the liquid from the container body via the nozzle head unit.
