摘要：
A fluid container according to the presentinvention includes a container body having upper and loweropenings, and further having a shoulder member and a sidewall which extend between the upper and lower openings. Thefluid container also includes a spacer abutting on theshoulder member of the container body, and a slidable valveslidably moving along an inner surface of the side wall ofthe container body in a hermetically sealed manner. Theslidable 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 thelower opening of the container body. Thespacer and theslidable valve include a spacer surface and a valve surface,respectively, opposed to each other and which are inclined attilt angles between 5 and 30 degrees relative to a horizontalsurface. Therefore, an airless fluid dispensing system usingthe fluid container securely prevents a small air bubble frombeing trapped in the container body when filled in with thefluid, thereby to dispense a constant dosage withoutrequiring undesired pumping actions prior to actual use.
