Vacuum bottle with dripless housing

Abstract

The invention discloses a vacuum bottle with a dripless housing, in particular to a water absorbing and removing ring as a newly-added part of a small-opening vacuum bottle. The detachable water absorbing and removing ring (2) covers the outer surface of a vacuum bottle housing shoulder (1) and is made of foam plastic or/and fabric fiber material with good water absorbability or/and sponge. An annular rib and a ring fixing column are arranged on the outer surface of the shell housing. By using the vacuum bottle, under the condition that the main body structure of the traditional vacuum bottle is unchanged, dripped water of the housing can be eliminated, the vacuum bottle housing is kept clean and sanitary, and water pouring and sanitary and clean placement of the vacuum flask are not influenced. The capacity of dripping water by the vacuum bottle is automatically regenerated, and the measure is convenient and the effect is stable and reliable.

Description

(1) Technical field [0001] The invention relates to a thermos bottle, in particular to a newly added part of a small-mouth thermos bottle—a water-absorbing and draining ring. (2) Background technology [0002] The thermos bottle that uses now has the problem of shell dripping, which affects the cleanliness of the thermos bottle body itself because of the dripping of water. Moreover, when the thermos bottle is lifted to pour water, the water dripping from the casing will drop to the place where the water is poured, and when the thermos bottle is put down, the water dripping from the casing will drip to the place where it is placed. Sometimes when the thermos bottle cover is opened, the condensed water on the inner wall of the cover will drop into the shell shoulder and the environment. Although the amount of water dripping from the shell will not be too much, it affects the cleanliness of the thermos bottle itself and the use environment, causing a trouble in using the therm...

[0003] On October 26, 2005, the "leak-proof thermos bottle" with the Chinese patent authorization announcement number CN2735907Y was announced, and on June 27, 2007, the "no-leakage thermos bottle" with the Chinese patent authorization announcement number CN2914973Y was announced, and on May 19, 2010 Announced the "leak-proof water thermos" with the Chinese patent authorization announcement number CN201469057U, their shortcoming is that the problem of hot water dripping inside the shell will occur, which is different from the current national standard GB/T11416-2002 "Daily Insulated Containers". 》4.2.4 The technical requirements of "hot water does not leak into the inside of the shell" are inconsistent

[0004] On April 30, 2008, the "new thermos bottle" with the Chinese patent authorization announcement number CN201052103Y was announced. Its shortcoming is that it cannot solve the problem of water dripping from the inner wall of the shell cover to the shell.
