Flip type thermos bottle cork

Abstract

The invention provides a flip type thermos bottle cork. By adopting the flip type thermos bottle cork, the following shortcomings are overcome: the existing thermos bottle corks are poor in heat insulation effect, poor in adaptability and easy to fall out in winter, and can accidentally drop and fall to the ground at any time, etc. In the bottle cork, three air layers playing the heat insulation role are arranged in a cork column of a cork body, and two heat insulation layers are arranged between the outer wall of the cork column and the inner wall of a bottle neck of a bottle liner; the free end of a long plate section 302-2 of a transfer strip 302 is clamped between an auxiliary bayonet and a main bayonet, and symmetrical rotating shafts at the free end of an arch-shaped section 302-1 are respectively clamped into two mutually symmetrical clamping rings in a cork seat; a heat insulation sheet 305 tight fit in a lower cork barrel 202 is clamped between an annular heat insulation sheet ridge of the lower cork barrel 202 and the end of an upper cork barrel; and a seal ring 301 with semi-circular-arc-shaped radial section is arranged around the outer wall of the lower cork barrel 202 through tight fit. By adopting the flip type thermos bottle cork, the heat insulation function of a thermos bottle can be significantly improved, the consumption of raw materials is reduced, and the flip type thermos bottle cork can be matched with the thermos bottles from different manufacturers and is easy to popularize.

Description

technical field [0001] The present invention is a household daily necessities accessory. Background technique [0002] Present glass thermos bottle stopper can be divided into two kinds of cork and plastic cork, and great majority is cork. At present, there is generally no connection between the cork of the thermos bottle and the thermos bottle. The radial elastic deformation of the cork sealing ring of the thermos bottle is small or it is located on the outer end surface of the bottle mouth of the glass liner of the thermos bottle. Barrel cover that snaps onto the neck of the plastic outer shell of a thermos. Contents of the invention [0003] Cork often has a peculiar smell, is easy to decay, and has poor heat preservation. It is easy to fall off in winter and will fall to the ground at any time. Some of the current plastic thermos bottle stoppers do not have sealing rings, and it is difficult to obtain good thermal insulation due to poor sealing; although some have s...
