Abstract
A fluid product reservoir, for a dispensing system, is made of a walled container having an aperture formed at one end thereof. A reservoir cap seals the aperture from exposure to the atmosphere. A pump integrated into the reservoir cap allows fluid product to be dispensed from a dispensing system. A venting mechanism is installed at the interface between the aperture and the reservoir cap to allow air from the atmosphere to displace fluid product as it is being dispensed. The venting mechanism includes a one-way valve, which permits air to flow into the reservoir but prevents fluid product from leaking out from the interface between the aperture in the reservoir cap.
