CN2728367Y - Self-closed thermos bottle stopper for controlling pouring water - Google Patents

Abstract

A self-closed thermos bottle stopper for controlling pouring water relates to articles for daily use and is suitable for controlling pouring water of thermos bottle and closing automatically. It is characterized in that it consists of four parts: a stopper body, a stopper core, a stopper cap and a sealing ring. The stopper body is a circular tube sample piece with large upper part, small lower part and hollow middle part. The upper part is arranged on the bottleneck and used for thermal insulation. One side of the stopper body is provided with a water outlet. The lower part can be inserted in to the bottleneck. The medial retreating bench is provided for locating the stopper core. The stopper cap is a seal closure for the top of the stopper body, and the stopper cap is not only a partition panel against thermal air in the upper part, but also a seal closure after the stopper core being put in to the stopper body. The stopper core is a valve core controlling outlet of water. The top of the stopper core is flat and round and the lower part of the stopper core is a vertical coning balance bar which is used to keep the balance of the stopper core and adjust the stopper hole for self-opening and self-closing. The sealing ring is a circular shaped silicon rubber ring which is arranged at the contacting part of the stopper body and the stopper core, the contacting part of the stopper body and the bottleneck and the lower position of the stopper body. The utility model is provided with well heat-insulating property. There is no need to pull the stopper when the utility model is in use. The utility model is not highly cost and provided with long service life.

Description

Self-closing pouring water and heat preservation plug of thermos

Technical field

The utility model relates to daily necessities, but is a kind of self-closing plug of thermos that vacuum flask need not be taken down the bottle stopper pouring that is used to be incubated.

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 heat-insulating property difference and inconvenient problem with use.The purpose of this utility model is for solving the deficiency of above-mentioned existence, provide a kind of and can be incubated and the new-type easily plug of thermos of pouring, need not pluck plug during pouring, stop to seal automatically behind the pouring, the sealing good heat insulation, and spilling water not, the life-span is long.

Summary of the invention

The utility model is to realize being incubated self-open and self-close with pouring with following technical scheme.

Plug of thermos mainly contains four parts and constitutes: cock body, plug core, gag and sealing ring.As seen from the figure, cock body is the round tube sample body of up big and down small a, hollow, above big part be seated on the bottleneck when using, be used for insulation, one side has an apopore and is used for pouring, below little part be inserted in the bottleneck, the platform place of moving back between up and down is used for putting the plug core; Gag is the seal closure on a cock body top, is the insulation air partition panel of the first half, also is the seal closure after the plug core is put into cock body, spins with the cock body upper end; The plug core is the spool of control water outlet, is seated in to move back platform place, flat above circle in the cock body, can seal the cock body upper and lower cavity is cut off moving back entablature, be a vertical tapered balancing pole below, be used to keep filling in the core balance and fill in opening certainly of core that anti-detent plug core departs from self-closing with adjustment; Sealing ring is circular silica gel circle or plastic tube, places end face and cock body under the seam crossing of cock body the latter half and thermos flask mouth and the plug core to move back the partition place of platform, simultaneously, cock body the latter half lean on the upper/lower positions place, also be with an anticreep sealing ring.The plug of thermos of this structure, its insulation effect are embodied in following two aspects, and the one, cock body that bottleneck is outer and the gag that spins have constituted an air chamber, and heat dispersion is poor, and the 2nd, the contact position sealed air-tight of bottleneck and cock body and cock body and plug core, temperature difference convection current is little.Convenient and the self-closing function of pouring is: need not draw the cork, current will fills in the core top and wash open during pouring, because the gravity effect of vertical conehead bar is arranged, it is an angle that the back is opened on the plug top, and then boiling water can flow out through the cock body apopore along open mouth; Bottle just returns after stopping pouring, and the plug core makes water bottle reach self-closing because of being subjected to the effect of vertical conehead bar also along with just returning and the cock body mesopore being covered completely.The utility model materials are nonpoisonous and tasteless plastics, and the plug wall will have certain rigidity, generally dispatches from the factory with thermos flask is supporting, also can produce listing separately.

Description of drawings

Fig. 1 is general assembly structural representation of the present utility model;

Fig. 2 is three-dimensional signal of the present utility model.

Among the figure, 1 is hollow cock body, and 2 are the plug core, and 3 is gag, and 4 is sealing ring,

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, not only be incubated but also handy, and cost is not high yet long service life.

(1)

The utility model is implemented to adopt nonpoisonous and tasteless engineering plastics to make than being easier to, and except that plug core body curve was more, total mould pattern was quite simple, and the lateral surface silk mouth that spins is only arranged, and is therefore, easy to assembly.

Make, press the accompanying drawing pattern, after cock body 1, plug core 2 and the integrated poured moulding of gag 3 die sinkings, the plug core 2 that will put sealing ring 4 earlier is presented in the cock body, after gag 3 is screwed onto on the cock body 1, other sealing ring 4 being enclosed within the cock body outside again and moving back in the ring recess at platform place and get final product, is the frictional force that increases cock body slippage bottleneck, cock body by descending the position also can install an anticreep sealing ring additional.

Use, by common usage, after thermos flask block taken off, need not extract bottle stopper, the direct pouring of portable thermos flask gets final product, outwards push open under the swash of wave of plug core 2 boiling water in bottle, boiling water flows out along plug core 2, stops behind the pouring thermos flask to be resetted, and plug core 2 cuts off cock body under the deadweight effect of vertical taper bar and reaches self-closing, buckle the thermos flask block, then pouring is finished.The utility model is mainly reflected in when using, and need not take down during pouring, and time saving and energy saving, water outlet is delighted, and automatic shutter is convenient and swift.

Claims (4)

1, a kind of self-closing pouring water and heat preservation plug of thermos is characterized in that: be made of cock body, plug core and gag, wherein, cock body be one up big and down small in the middle of empty round tube sample body, above big part, a side has apopore, below little part can be plugged in the bottleneck, mid portion moves back platform; The plug core is a spool, moving back the platform place and will move back entablature and seal in the middle of being seated in the cock body; Gag is the seal closure on a cock body top, spins with the cock body upper end.
