Abstract

The utility model discloses a thermos bottle plug capable of being automatically opened and closed. It is composed of fixed part and movable part to perform switching function. It is based on the dead weight of the movable plug to complete the sealing in vertical position and the opening in inclined position. The bottle stopper not only can well insulate heat and preserve heat, but also can save the trouble of pulling the bottle stopper and the bottle stopper when pouring water, and has the advantages of sanitation and convenience.

Description

Vacuum bottle plug capable of automatic opening and closing

The utility model relates to a kind of hot water thermal insulating bottle stopper, and the particularly a kind of hot water thermal insulating bottle stopper that can open automatically and close automatically is applicable to all family expenses ordinary hot thermos bottles.

The hot water thermal insulating bottle of using in living now, the intake-outlet of its upper end all uses a cork or hollow plastic plug to clog, and its objective is to preventing that heat scatters and disappears.But the disadvantage of this bottle stopper is, from vacuum flask outside when falling hot water, all will earlier it be extracted with hand at every turn, fallen behind the water, more beyond the Great Wall with it, so unusual inconvenience.

The purpose of this utility model provides a kind of novel hot water thermal insulating bottle stopper, and it is heat-insulation and heat-preservation well not only, more can open and close automatically bottleneck when each pouring, has saved the trouble with hand-lifting plug and capping plug.

In order to realize above purpose, the utility model is made such, it is that fixed cover and movable part are that motion stops two parts are formed by standing part, the fixed cover outside dimension matches with the internal diameter of insulation bottleneck, make fixed cover can install in the bottleneck, the contact portion of motion stops and fixed cover can be coincide well.One guide rod and balancing weight are arranged, scope of activities that can the restraint plug below the motion stops.The motion stops upper end can add dustproof skirt, can prevent that dust from falling into bottleneck.The utility model insulation bottleneck of packing into is when needs outwards during pouring, are picked up vacuum flask from vacuum flask, the aligning water tumbler is toppled over, because the deadweight of motion stops, it will be moved bottleneck is opened, water just flows out, vacuum flask is recovered erectility, because the deadweight of motion stops, it is depressed again, with the fixed cover tight connecting, close bottleneck, reached heat insulation purpose again, greatly facilitated pouring like this.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Accompanying drawing is that the utility model is installed in the profile in the vacuum flask.

In the accompanying drawing, fixed cover (1) is filled in the vacuum flask (6), and motion stops (2) is in the top of fixed cover (1), and a guide rod (3) and balancing weight (5) being arranged below the motion stops (2) is restraint plug scope of activities.The upper end of motion stops (2) has dustproof skirt (4) can prevent that dust from falling into bottleneck.When vacuum flask (6) is upright, motion stops (2) is because deadweight, be pressed on the fixed cover (1), played good sealing function, when inclination vacuum flask (6), because the deadweight of motion stops (2), it will break away from and the coincideing of fixed cover (1), and water is flowed out, and vacuum flask (6) is upright, just get back to the state that motion stops (2) is pushed down fixed cover (1) again, promptly sealed keeping warm mode.

When injecting hot water in the thermotropism thermos bottle (6), motion stops (2) taken out getting final product.

Claims

1, a kind of hot water thermal insulating bottle stopper that can open and close automatically is characterized in that: it is made of fixed cover (1) and motion stops (2) two parts.

2, by the described hot water thermal insulating bottle stopper of claim 1, its feature also is: a guide rod (3) is arranged at motion stops (2) bottom.
