CN2552445Y - Thermos bottle stopper - Google Patents

Abstract

The utility model discloses an underground stream thermal bottle stopper, used for double-layer thermal bottle with stainless steel in general, which aims to overcome the deficiency of prior thermal bottle stopper with high cost of the product and high failure rate in use for the complex mechanical structure. The utility model is characterized in that: an outside cover is arranged on the top of the body, the end of the outside cover extends out of the lateral face of the body, the body forms shrinks and forms a neck and a shoulder at the connecting part of the outside cover, and a sealing ring is sleeved on the body and is closely to the lower part of the edge of the outside cover, the sealing ring is positioned in the upper part of the shoulder, a plurality of longitudinal channels are arrayed along the lateral face of the body, the upper ends of the longitudinal channels are communicated with the lower part of the sealing ring in shoulder part, while the opening of the lower ends of the longitudinal channels are communicated with the inner part of the thermal bottle on the bottom of the body, the liquid in the bottle can flow outside from the longitudinal channels. The utility model has the advantages of convenient use-the required function can be realized only by winding up or winding down the thermal bottle stopper, low cost and long service life.

Description

Underground stream formula plug for vacuum bottle

Affiliated technical field

The utility model relates to the plug for vacuum bottle that a kind of daily life is used.

Background technology

The plug for vacuum bottle of commonly using at present is a lot, and the bottle stopper that is used for the double-layer stainless steel vacuum bottle is push button mostly, and this push button bottle stopper inside is provided with spring and a series of associated mechanical structure, makes manufacturing cost height, assembling also complicated.Again because complex structure makes that fault rate is also higher when using.

Summary of the invention

Thereby the higher deficiency of fault rate when causing cost of product height and use owing to complicated in mechanical structure in order to overcome existing plug for vacuum bottle.The utility model provides a kind of underground stream formula plug for vacuum bottle, and this bottle stopper is simple in structure, easy to use and service life is longer.

The utility model for the technical scheme that solves its technical matters and adopt is: bodies top is provided with enclosing cover, the enclosing cover edge stretches out the body side, body dwindles in the position with the enclosing cover joint and forms neck and shoulder, again, sheathed one seal ring that is right after the enclosing cover edge lower part on the body, seal ring is in the shoulder top, several vertical passages are arranged along the body side, the vertical passage upper end open is in the seal ring below in shoulder and communicates with the external world, and the vertical passage lower ending opening communicates with vacuum bottle inside in the body bottom.

The body lower external face is provided with screw thread.

The beneficial effects of the utility model are: when depositing at ordinary times, the utility model is tightened in the insulation bottleneck, and the seal ring one side on the body is close to another side with enclosing cover and mouth cylindrical part is close to, and like this, vacuum bottle seals fully, and the liquid that can not accident is reserved in the bottle; When drinking, unscrew the utility model, seal ring is away from bottleneck, and the vertical passage and the external world communicate, the inclination bottle, and liquid can flow out from vertical passage in the bottle.Therefore people use easily, only need screw or unscrew the utility model and can realize required function.

The specific embodiment

Embodiment 1: referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of underground stream formula plug for vacuum bottle, body 1 is hollow form, enclosing cover 20 is shell-like, enclosing cover 20 is sleeved on body 1 top, enclosing cover 20 edges stretch out body 1 side, body 1 is dwindling formation neck 10 and shoulder 11 with enclosing cover 20 joints, seal ring 30 is sheathed on neck 10 tops and is close to enclosing cover 20 edge lower part, be provided with several are circumferential arrangement along body 1 sidewall vertical passage 40 again, vertical passage 40 lower ending openings communicate with vacuum bottle 90 inside in body 1 bottom surface, vertical passage 40 upper end open are in seal ring 30 belows and the external world communicates in the shoulder 11 of body 1, and body 1 lower external face is provided with the outside thread that is complementary with 90 mouthfuls of negative threads of vacuum bottle.

Referring to Fig. 6, use of the present utility model is: the utility model is tightened in vacuum bottle 90, promptly not understanding outer outflow of liquid in the bottle 90, in order to fall liquid better, can make vacuum bottle tubaeform for 90 mouthfuls, the utility model is sealed in the horn opening bottom, and a duckbill current deflecting device 91 is set in the horn opening somewhere, all flows out from duckbill current deflecting device 91 from the bottle 90 interior liquid that flow out like this; When drinking, unscrew the utility model, bottle 90 bodies tilt, under duckbill current deflecting device 91 placed, liquid can flow to duckbill current deflecting device 91 by vertical passage 40 (or vertical passage 40 and interconnection 50) in the bottle 90, flows to the container that sets from duckbill current deflecting device 91 then;

Can find out that therefrom structure of the present utility model is very simple, can not break down substantially during use, and easy to use, only need screw or unscrew the utility model.Generally speaking, the utility model manufacturing is simple, cost of product is low, easy to use and long service life.
