Abstract

A fluid container according to the present invention includes a container body having upper and lower openings, and further having a shoulder member and a side wall which extend between the upper and lower openings. The fluid container also includes a spacer abutting on the shoulder member of the container body, and a slidable valve slidably moving along an inner surface of the side wall of the container body in a hermetically sealed manner. The slidable valve defines a container space for holding fluid, in conjunction with the side wall of the container body. Further, a bottom cover is provided for covering across the lower opening of the container body. The spacer and the slidable valve include a spacer surface and a valve surface, respectively, which oppose to each other and are inclined at tilt angles between 5 and 30 degrees relative to a horizontal surface. Therefore, an airless fluid dispensing system using the fluid container securely prevents a small air bubble from being trapped in the container body when filled in with the fluid, thereby to dispense a constant dosage without requiring undesired pumping actions prior to actual use.
