Abstract

A self-closed simple thermos flask stopper utility model is a self-closed and capable of pouring water simple thermos flask stopper which is suitable for thermos flask. It consists of a stopper body, a stopper cap, a hinged shaft and a sealing ring. It is characterized in that the stopper body is a hollow rivet shaped circular plastic cycle. The upper of the stopper body is arranged on the bottleneck when it is in use, and the lower part of the stopper body is inserted into the bottleneck and the hollow part is for pouring water. The stopper cap is arranged at the top of the stopper body and hinged with the stopper body. The size of the stopper cap is consistent with that of the upper end of the stopper body. The stopper cap is provided with two forms, one is a circular flat body and another one is a semi-embedding body. That is to say the retreating bench part on the lower part of the cap can be inserted into the port of the stopper body and all hinged with the stopper body by the hinge shaft 4. The sealing ring is shrunk on the joint of the stopper cap and the stopper body and the joint of the stopper body and the bottleneck, which not only has effect as partition against convection of hot gas, but also enlarges the force of friction for the stopper out of the bottleneck. The most significant advantage is that it saves money without losing prior function and directly pours water and is self-closed so that the trouble of pulling and inputting the stopper is avoided.

Description

The simple and easy plug of thermos of self-closing

Technical field

The utility model relates to daily necessities, is a kind of simple and easy plug of thermos of self-closing that the insulation vacuum flask is used that is matched in.

Background technology

Traditional plug of thermos is a cork solid plug, will draw the cork during pouring, capping plug, and total life-span is short, the difficulty of drawing the cork during water swelling, the time spent again can drying shrinkage for a long time, though the back is substituted by hollow plastic products gradually, but using method not to become, and also will draw the cork and capping plug, always feels some trouble.Along with the raising day by day of living standard, though some so-called hygiene-types are arranged, gag is one-piece type or the case type bottle stopper of buckle closure occurs in succession or scheme is open, but still have inconvenient and the high problem of expense used.The purpose of this utility model is for solving above-mentioned existence deficiency, provides a kind of not only pouring convenient but also need not move the simple and easy plug of thermos of plug, can seal automatically after having fallen, and handy not spilling water, cost is low, long service life.

Summary of the invention

The utility model is to realize pouring and self-closing with following technical scheme.

Plug of thermos mainly is made of four parts: cock body, gag, jointed shaft and sealing ring.By accompanying drawing as seen, cock body is the round plastic circle of a tubular rivet sample, and upper part is seated on the bottleneck when using, and lower part is inserted in the bottleneck, and hollow is used for water flowing; Gag is that the seal closure and the cock body on a cock body top is hinged, and size is consistent with the upper port of cock body, a kind of form is a tabular, directly falls to being placed on the cock body mouth along last, and a kind of form is half embedding shape, the platform that moves back of gag is partially embedded in the cock body mouth, can improve heat insulating ability; Jointed shaft combines gag and cock body; Sealing ring be enclosed within on the cock body and the thermos flask mouth patch on place and the gag and the junction of cock body, can cut off the aqueous vapor convection current, play insulation effect, increase friction simultaneously and guarantee that stopper can not come off when pouring.The plug of thermos of this structure, time spent need not be drawn the cork and can be made the inside and outside temperature difference convection current of bottle little, has the convenient and self-closing function of pouring, need not draw the cork, the impulsive force during by pouring backs down gag, makes gag that one subtended angle be arranged, then boiling water can flow out along open angle, fallen that bottle just returns behind the water, the gag nature is tight with the cock body flap along with just returning, and makes water bottle reach self-closing.The utility model materials are nonpoisonous and tasteless plastics, and the cock body wall will have certain rigidity, and as the double wall that is made into hollow easy to process, then heat insulating ability is better, generally are that supporting thermos flask dispatches from the factory together, also can make sale separately.Great advantage of the present utility model is not lose saving money and directly water flowing and self-closing under the original function, the trouble with connector of not drawing the cork.

Description of drawings

Accompanying drawing 1 is general assembly structural representation of the present utility model;

Accompanying drawing 2 is flat gag combination signal;

Accompanying drawing 3 is the gag combination signal of half built-in.

Among the figure, 1 is cock body, and 2 is gag, and 3 is sealing ring, and 4 is jointed shaft.

The specific embodiment

The utility model generally is that supporting thermos flask dispatches from the factory together, has included standardization in because of producing, so also can go on the market separately, both handy, cheap again, service life is also long, is suitable for general family and uses.

The utility model is implemented to adopt nonpoisonous and tasteless engineering plastics to make than being easier to, and the mould pattern is simple, only has a cover plate pin joint to bother slightly, but easy to assembly.

(1)

Make, press the accompanying drawing pattern, fixed with jointed shaft 4 strings after cock body 1, the integrated poured moulding of gag 2 die sinkings, sealing ring 3 is set to the design attitude place gets final product.

In embodiment 1, the utility model, described gag form is one certain thickness circular platysome, directly falls to being placed on the cock body mouth along last by twisted axis 4 is hinged.

Embodiment 2, the utility model, described gag form is one and half embedded bodies, lid moving back the platform part and can be embedded in the cock body mouth down is hinged by twisted axis 4 and cock body.

Use, press common usage, after the thermos flask block is taken off, need not extract bottle stopper, the direct pouring of portable thermos flask gets final product, gag 2 swash of wave of boiling water in bottle subtended angle that has a down dip, and boiling water flows out along subtended angle, fallen and thermos flask is resetted behind the water, gag 2 covers cock body under self-gravity action, and pouring is finished.

Claims (5)

1, the simple and easy plug of thermos of a kind of self-closing is made up of cock body and gag, it is characterized in that: cock body is the round plastic circle of a tubular rivet sample, and upper part is seated on the bottleneck when using, and lower part is inserted in the bottleneck, but the hollow water flowing; It is hinged that gag is put the top and the cock body of cock body, and size is consistent with the upper port of cock body.
