A water dispenser is provided in which proliferation of bacteria is less likely to occur in a gap between a guiding cylindrical portion of a cap attached to a raw water container and a joint portion. In the above mentioned water dispenser, the cap (45) includes an inner tube (46) protruding into the interior of the raw water container (4) and defining a water outlet port (14) of the raw water container; and a plug (47); wherein the inner tube (46) is provided with a stepped portion (48) having a smaller diameter at its portion closer to the interior of the raw water container (4), and a fastening belt portion (49) formed contiguous to the stepped portion (48) on the smaller diameter side thereof. The plug (47) includes a bottomed cylindrical portion (51) configured to be fitted to the inner tube (46), a fitting surface (52) configured to be fitted to the fastening belt portion (49) with an interference fit, and an engaging portion (53) configured to engage with the stepped portion (48). The joint portion (15) comprises a cylindrical member including a straight portion (73) configured to be fitted to the fastening belt portion (49) with an interference fit, and a tip portion (74) configured to be fitted inside the bottomed cylindrical portion (51). The straight portion (73) is provided with a water flow hole (75) configured to open to the interior of the raw water container (4) at a position away from the inner tube (46). The water flow hole (75) is formed in a size so as not to cover the entire axial width of the fastening belt portion (49) while the straight portion (73) is being inserted into the fastening belt portion (49). |
