The invention relates to the technical field of medical instruments, in particular to a container for containing a thermometer. The container comprises a box (1), wherein a cover (2) is arranged on the top of the box (1); the depth of the box (1) is greater than the length of the thermometer; the box (1) is divided into a plurality of units by catches (3); the height of each catch (3) is smaller than the depth of the box (1); the bottom of the cover (2) is connected with an occupying block (4); the occupying block (4) is located inside the box (1); the size of the occupying block (4) is 1/10-1/2 of the volume of the box (1); an overflow gap (5) is formed in the position, close to the upper edge, of the occupying block (4); when the cover (2) covers the box (1), the overflow gap (5) is lower than the upper edge of the box (1). The operation steps of using a pair of forceps to clamp the thermometer and throwing the thermometer forcedly are omitted, the probability that the thermometer creeps down and is broken is reduced, the simplicity and convenience of operation are increased, and the working efficiency of doctors is improved.
