SHOCK-ABSORBING LOWER STRUCTURE OF AN AIRLESS TYPE DISPENSER

Document Type and Number:

WIPO Patent Application WO/2014/021505

Kind Code:

A1

Abstract:

The present invention relates to a shock-absorbing lower structure of an airless type dispenser, in which a support member made of elastic material is arranged in a lower portion of a piston to provide a cushioning function so as to support the lower end of the piston in the main body of the dispenser. Thus, when the piston is lowered to press a base by the shock applied from an external source, the base is prevented from escaping from the main body of the dispenser. Further, the base or a pumping member is prevented from escaping and the pumping member is prevented from being damaged when the volume of the content expands at a low temperature state.
