Non-return leakage-proof bottle cap and container

The utility model relates to a retaining leakproof bottle cap and a container, the retaining leakproof bottle cap comprises a metering cap and a base, the metering cap is connected with the base through a first thread assembly, a disposable first retaining assembly is arranged between the metering cap and the base, and the first retaining assembly comprises a clamping block arranged on the metering cap and a retaining block arranged on the base; after the metering cover and the base are screwed together, the clamping block is limited to the retaining face side of the retaining block, and the clamping block removes the retaining block from the base until the metering cover is subjected to unscrewing force larger than a preset value. By the adoption of the retaining leakage-proof bottle cap and the container, the phenomenon that the metering cap retreats due to external force in the transportation process can be effectively avoided, liquid in the container is prevented from leaking, meanwhile, due to the fact t
