Problems solved by technology

[0002] Most of the existing thermos bottles all adopt wooden conical structure as the cork of the thermos mouth; when the cork of this structure is in use, after the thermos bottle is filled with hot water, the cork is immediately covered. It is easy to cause the bottle stopper to fall off due to the increase of air pressure in the thermos bottle. At this time, if it is not found in time, the hot water in the thermos bottle will quickly turn into cold water, thus losing the heat preservation effect

Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] as attached figure 1 The shown bottle stopper of the present invention comprises a plug body 1 and a plug cap 2; the plug body 1 is conical; the plug cap 2 is arranged on the upper end of the race body 1; An annular groove 3 is provided at the joint of the plug body 1 ; a vent hole 4 is provided on the plug body 1 and the plug cap 2 ; a plug 5 is provided at the outlet of the vent hole 4 .

[0013] When in use, the plug body 1 is inserted into the mouth of the thermos bottle to seal the thermos bottle; the annular groove 3 is stuck on the outer edge of the mouth of the thermos bottle; Stopper 5 flows out, and the high air pressure in the thermos bottle can be released from the air hole, so the bottle stopper of the present invention will not come off from the thermos bottle mouth; , because the air vent 4 is relatively small,...

Abstract

The invention discloses a bottle stopper. The bottle stopper comprises a cone-shaped stopper body and a stopper cap arranged at the upper end of the stopper body. The stopper body and the stopper cap are provided with ventilating holes. Plugs are arranged on outlets of the ventilating holes. When the bottle stopper is used, if the air pressure in a hot water bottle is too high, high-pressure airflow will rush out of the ventilating holes, make the plugs separated and flow outwards to release high air pressure in the hot water bottle through the ventilating holes, and the bottle stopper will not drop from an opening of the hot water bottle. Meanwhile, even if it is not recognized that the plugs are opened through rushing, because the ventilating holes are small, heat dissipation is slow, and the phenomenon that hot water in the hot water bottle turns cold very quickly will not happen.

Description

technical field [0001] The invention relates to a bottle stopper, in particular to a bottle stopper which can prevent falling off from the mouth of a thermos bottle due to high pressure inside the bottle. Background technique [0002] Most of the existing thermos bottles all adopt wooden conical structure as the cork of the thermos mouth; when the cork of this structure is in use, after the thermos bottle is filled with hot water, the cork is immediately covered. It is easy to cause the bottle stopper to fall off due to the increase of air pressure in the thermos bottle. At this time, if it cannot be found in time, the hot water in the thermos bottle will quickly become cold water, thus losing the heat preservation effect. For this reason, we have developed a cork that prevents the bottle from falling off the mouth of the thermos due to the high pressure inside the bottle. Contents of the invention [0003] The purpose of the present invention is to provide a bottle stopp...
