When the position of the water bottle is lowered, it is not necessary to lift the water bottle high when setting a full water bottle having a considerable weight to the water server, so that the water bottle can be easily replaced.
- the water bottle When the water bottle is arranged in the lower part of the water server, the height of the water bottle relative to the cold water tank is lowered, so that it becomes difficult to supply the drinking water filled in the water bottle to the cold water tank due to gravity drop. Therefore, in order to be able to supply drinking water from the water bottle to the cold water tank, it is necessary to provide a pump for pumping drinking water from the water bottle in the water server.
- the inventor of the present invention adopts a water bottle that contracts as the amount of remaining water decreases, and if the water server is provided with a pump that draws drinking water from the water bottle, Since it is not necessary to place the water outlet at the lowest position of the water bottle as it is dropped, the water bottle is placed sideways when the water bottle is set in the water server (i.e., the neck of the water bottle is oriented horizontally). We focused on the point where it was possible to
- the degree of freedom in designing the water server increases.

- the drinking water inside the water bottle decreases and the water bottle contracts, there is a problem that the drinking water tends to remain in the region along the mounting surface of the water bottle and the remaining water amount increases when the water bottle is replaced. I found out. This will be described below.
- the problem to be solved by the present invention is to provide a water server that can draw out the drinking water inside the water bottle as far as possible with the neck of the water bottle oriented horizontally.

- Raw water pumping pipe connected to the water outlet of the water bottle;
- the water server has a configuration in which a convex portion is provided on the upper surface of the bottle mounting plate for inducing that the portion of the body of the water bottle that contacts the bottle mounting plate is folded inward when the water bottle contracts. It was.
- a protrusion formed so as to extend across the center of the body of the water bottle can be employed as the protrusion.
- a slope that descends from the top of the convex portion to the water outlet side of the water bottle and a slope that descends from the top of the convex portion to the side opposite to the water outlet of the water bottle are formed, and the convex portion It is preferable to adopt a configuration in which the inclination angle of the slope that descends from the top of the water bottle to the opposite side of the water outlet of the water bottle is set to 30 ° or less. In this way, when the drinking water inside the water bottle is pumped out from the water outlet and the water bottle contracts, the situation where the deformed water bottle is caught on the convex portion and prevents the water bottle from contracting is prevented. Can do.
- PET polyethylene terephthalate resin
- the portion of the body of the water bottle that contacts the bottle placing plate is bent by the convex portion, and is stretched. Absent. Therefore, when the drinking water inside the water bottle is pumped out by the pump, the portion of the body portion of the water bottle that contacts the bottle mounting plate is deformed so as to be folded inward by the reduced pressure inside the water bottle. Therefore, when the water bottle contracts, it becomes difficult for the drinking water to remain in the area along the bottle mounting plate, and the drinking water inside the water bottle can be pumped out to the end as much as possible.
