As improvement, described swivel nut is working of plastics, and the outer wall middle part hoop of swivel nut is provided with a convex tendon, and the inwall middle part of inner casing forms corresponding annular groove, and swivel nut is pressed in inner casing and is snapped in annular groove fixing by convex tendon by dimensional fits.

As improvement, the upper center of described swivel nut is recessed forms the protruding boss with two step surfaces downwards, on the step surface of boss, is connected to a clasp by supersonic welding, on clasp, be socketed with one with cup on the first sealing ring of offseting of the mouth that drinks water.

Improve, the cross section of described clasp is Z-shaped again, and clasp is welded on the leave from office terrace of boss, and the cross section of the first sealing ring takes the shape of the letter U, and the first sealing ring is socketed in the sealing that offsets of the outer end of clasp and the terrace of appearing on the stage of boss.

Improve, described cup has the vacuum interlayer of thermal and insulating performance again, and the upper end of cup is provided with the external screw thread being threaded with swivel nut, and the mouth that drinks water is fixedly installed in the opening's edge of cup, is lined with the second sealing ring drinking water between mouth and cup.

Compared with prior art, the utility model has the advantage of: cup has vacuum interlayer, the enclosing cover of bowl cover is the stainless steel cover with vacuum interlayer, with cup reasonable coordination, has greatly improved the thermal and insulating performance of thermos cup; Swivel nut is connected in the inner casing of enclosing cover by convex tendon, is not only connected firmly, also for convenience detach, is convenient to daily cleaning, and swivel nut is provided with the mouth good seal that drinks water of sealing ring and cup, has also further improved heat-insulating property. The utlity model has feature rational in infrastructure, easy to use, heat-insulating property is good.
