Vacuum flask with novel case mouth

Abstract

The invention discloses a vacuum flask with a novel case mouth. The vacuum flask is characterized in that the novel case mouth (1) is provided with a waterspout (2); the waterspout (2) is positioned on the side wall of the case mouth (1) over the handle (4) side of a shell body (3); and the height of the bottom of the waterspout (2) is equal to the height of the upper surface of an adjacently connected port ring (5). By using the vacuum flask, remained water which is drained and retained in the groove of the case mouth can be conveniently discharged under the condition that the traditional main structure of the vacuum flask is not changed, thereby improving the temperature and sanitation degree of supplied hot water; and hot water which can be used in the groove of the case mouth can not be discharged, thereby avoiding the waste of hot water which can be used. The use mode of the vacuum flask disclosed by the invention is simple and labor-saving, without additional manpower control.

Description

(1) Technical field [0001] The invention relates to a thermos bottle, in particular to a shell nozzle of a common small-mouth thermos bottle. (2) Background technology [0002] The ordinary small-mouth vacuum flasks that are produced and sold on the market now include bottle liners, bottle stoppers, mouth rings, shell covers, shell shoulders, shell bodies, shell bottoms, handles and shell mouths. There are related standards in the industry standard QB / T3723-1999 "Terminology for Vacuum Bottles". For the mouth of the shell, the standard has such content as "1.11 The mouth of the shell is installed on the shoulder of the shell and is higher than the mouth-shaped part of the bottle mouth". From the standard " figure 1 "Schematic diagram of the structure of a small-mouth thermos bottle", it can be seen that the shell mouth is outside the bottle liner, and there is a mouth ring in the middle to seal it. A nearly ring-shaped shell mouth groove is formed inside the shell mouth, o...

AI Technical Summary

Problems solved by technology

But when the water is poured once, the above-mentioned stored water that is immediately discharged from the bottom of the side wall of the shell mouth is hot water that can be used for the next pour of water in a row, because of its temperature and hygienic cleanliness It will not quickly become unusable in the next pouring, so the solution of this patent to eliminate the water storage in the groove of the shell spout is not enough to save the available hot water of the thermos bottle

Furthermore, after every time the water is poured, the unused water is quickly discharged from the bottom of the side wall of the shell mouth. If there is no reliable corresponding measure to eliminate the dripping of the shell, it will inevitably affect the cleanliness of the pouring environment.
