Abstract
The present invention relates to a shock-absorbing lower structure of an airless type dispenser, wherein a support member made of elastic material is arranged in a lower part of a piston to provide a cushioning function so as to support the lower end of the piston in the housing of the dispenser. Thus, when the piston descends and presses a housing support by the shock applied from an external source, the housing support is prevented from being separated from the housing of the dispenser. Furthermore, when content expand in volume at a low temperature, not only is a housing support or a pumping member prevented from being separated, but also the pumping member is prevented from being damaged.
