Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Example 1

As shown in fig. 1 to 3, a bottom structure of a thermos bottle comprises a shell 1 and an inner container 2 arranged in the shell 1, wherein the shell 1 comprises a main body shell 11 and a bottom cover 12 arranged below the main body shell 11, the top of the bottom cover 12 is clamped with the bottom of the main body shell 11, and the bottom cover 12 is arranged below the main body shell 11 in a beating mode during assembly, so that the assembly can be completed. The assembly is more convenient, and the condition of turning into and blocking can not appear.

Specifically, outer wall integrated into one piece in bottom 12 top has joint cooperation portion 121, and joint cooperation portion 121 includes domatic section 1211, circumferential groove section 1212 and vertical section 1213 from the top down, and domatic section 1211 is narrow down wide down, and the bottom 12 of being convenient for assembles into main body shell 11, and the inner wall integrated into one piece in main body shell 11 bottom has the circumferential rib 111 with circumferential groove section 1212 assorted.

The mounting hole 122 has been seted up at bottom 12 middle part, fixedly in the mounting hole 122 being provided with fixed lid 3, be provided with the screw thread on the 3 lateral walls of fixed lid, guarantee the firm of installation, be provided with packing ring 4 between inner bag 2 and the

bottom

12, 4 top surfaces of packing ring and 2 bottom surface looks butt of inner bag, packing ring 4 is the silica gel material, and the setting of packing ring 4 makes the position of inner bag 2 more stable.

In this embodiment, the main body case 11 has an approximately octahedral thin-walled structure.

Example 2

The thermos bottle of embodiment 2 and the thermos bottle of embodiment 1 all adopt the assembly method of joint, the difference lies in that the concrete structure of joint has a difference, in embodiment 2, integrated into one piece has first circumferential protruding muscle 123 on the lateral wall of bottom 12, integrated into one piece has second circumferential protruding muscle 112 on the inner wall of main part shell 11 bottom, the internal diameter of second circumferential protruding muscle 112 is less than the external diameter of first circumferential protruding muscle 123, like this, after bottom 12 blocks into main part shell 11, second circumferential protruding muscle 112 can prevent that first circumferential protruding muscle 123 from deviating from downwards, guarantee bottom 12 and main part shell 11 firm in connection.

The lower surface of the first circumferential rib 123 is a first inclined surface, the upper surface of the second circumferential rib 112 is a second inclined surface, the second inclined surface is abutted to the first inclined surface, and the clamping is more stable due to the matching of the two inclined surfaces.
