A liquid bag with double ziplock closures having a bag body is provided. An upper part of the bag body is provided with a first ziplock closure and a second ziplock closure. The first ziplock closure is positioned above the second ziplock closure. The liquid bag has a simple structure and a reasonable design. It can be used together with a urinary device so that female users may urinate at any time in a standing position and therefore no longer suffer from withholding urine. After using the urinary device to urinate, the liquid bag is first sealed by the first ziplock closure since some splashes of urine may be left between the two ziplock closures during urination, subsequent sealing of the liquid bag by using the second ziplock closure can prevent contact between users hands and the splashes of urine, and can achieve tighter locking effect so that liquid inside the bag will not leak out. The liquid bag used together with the urinary device minimizes the undesirable physical and psychological impact caused by withholding urine and relieves the psychological stress of users caused by their realization of the need to withhold urine, thereby promoting the health of the users.
