Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of DGT overcoats of high leakproofness, as shown in Figure 1 and Figure 2, including base 1 and the sealing that is hinged with the one end of base 1
Lid 2, base 1 is provided with the first groove 3, and the periphery of the first groove 3 is provided with one annular groove 4；Closure 2 is provided with and the first groove
3 corresponding and sizes are additionally provided with the sealing projection matched with annular groove 4 less than the through hole 5 of the first groove 3 on closure 2
6。
Base 1 is provided with locking device with the side relevant position of closure 2.Locking device is favorably improved the sealing of device
Property.
Locking device includes the second groove on base 1 and the buckle on closure 2.
Locking device is hasp.
