1. A product dispenser, comprising:
a. a reservoir for a product, having a cap fastening mechanism,
b. a cap comprising:
i. a first assembly comprising:
1. a housing for a sealing element;
2. a chamber volume controlling mechanism; and
3. a button configured to dispense the product through a lower end orifice of a pipette, when the button is actuated;
ii. a second assembly comprising:
1. the pipette having an upper end orifice and the lower end orifice, and rigidly connected and in fluidic communication with a chamber;
2. the sealing element configured to seal relative to the housing, and to slide between a high position and a low position in the housing; a corresponding fastening mechanism to the cap fastening mechanism of the reservoir;
3. the chamber configured to change the chamber volume depending on movement of the first assembly relative to the second assembly and movement of the button;
wherein when the cap is in a closed position, the sealing element is located at a higher position relative to the housing,
wherein a movement of the cap in a direction of opening the product dispenser causes the housing to move up relatively to the sealing element via the chamber volume controlling mechanism, so that the sealing element slides from the higher to the lower position in the housing and the volume of the chamber increases,
wherein the increase of the chamber volume causes a suction of the product in the pipette,
wherein when the sealing element reaches to the lower position in the housing, a further movement of the cap in the direction of opening causes the corresponding fastening mechanism of the cap to disengage from the cap fastening mechanism of the reservoir,
wherein when the button is actuated, the volume of the chamber decreases by which the product is dispensed from the pipette.
