A vessel includes a body, an intermediate cover, and an upper cover; the intermediate cover is positioned above an upper opening of the body, and has a spout, which forms a liquid outlet of the vessel together with a corresponding spout formed on the body; the upper cover is threadedly joined in the upper end of the body to fix the intermediate cover to the body; the spout of the body has a transverse upwards-sticking first stopping portion, and the spout of the intermediate cover has a transverse downwards-sticking second stopping portion; the first and the second stopping portions are a distance from each other, and the uppermost end of the first stopping portion is higher than the lowermost end of the second stopping portion; thus, the stopping portions together make it difficult for poisonous substance to be added the contents of the body through the outlet.
