Abstract: A dispenser system for dispensing a fluid product comprises: an elongated container containing the fluid product to be dispensed, a pump assembly coupled with the elongate container from the distal end, a piston which is slidably positioned in the container at the closed proximal end and contacting with the fluid product, and a standing cap. The standing cap has an opening for engaging the pump assembly, and has a supporting structure opposite to the opening, wherein the supporting structure comprises one or more supporting sections that define a supporting plane, wherein the dispenser system, when in a main standing position, stands upon the supporting structure of the standing cap, with the closed proximal end of the elongated container is on the topmost. Further the supporting structure of the standing cap has a projected area on the supporting plane which is larger than the largest cross-sectional area of the elongated container.
