For solving above-mentioned task, the solution that the present invention takes on the plug of thermal bottle bottleneck, lid is: plug (2) and lid (6) are making or the disjunctor plug, the lid that connect as one.

Has the outstanding tabula (3) of several elastic rings on above-mentioned utensil and the position that vessel port contacts.

Above-mentioned utensil has seal cavity (5), and the air pressure in the seal cavity (5) is lower than ambient atmosphere pressure.

The reflex-reflective material or the device that have counter radiation in the above-mentioned utensil.

For solving above-mentioned task, the solution that the utility model is taked on the plug of vacuum heat-insulating container vessel port, lid is: plug (2) and lid (6) are disjunctor plug, the lids of making or connecting as one, with the position of vessel port (1) contact on have with several elastic rings that the vessel port transverse plane is similar to parallel or same trend and give prominence to tabula (3).

The position that above-mentioned utensil clogs vessel port has groove structure (4), is used to hinder the transmission of heat on the vessel port.

Thereby reach easy to use, only need open and two actions of gag, do not jump plug, fried courage makes easy to carry, the spilling water not of container, and is attractive in appearance, the good purpose of insulation timeliness.With five pounds of thermal bottle is example, is 20 degree Celsius in ambient temperature, and injecting water temperature is 99 degree Celsius, uses plug of the present utility model, lid, and water temperature is reduced to 80 degree Celsius after 24 hours, and uses former stopper to add upper cover, then reduces to 69 degree Celsius.With 2 pound half, bore is that the insulation jar of 100MM is an example, is 20 degree Celsius in ambient temperature, and injecting water temperature is 99 degree Celsius, uses plug of the present utility model, lid, and water temperature is reduced to 93 degree Celsius after 4 hours, uses former lid then to reduce to 71 degree Celsius.So this utensil makes vacuum heat-insulating container can generally utilize boiling water or high temperature liquid slaking meat, beans, eggs, cereal, potato class or the like food.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the longitudinal diagram of the utility model plug, lid embodiment on the thermal bottle bottleneck.

Fig. 2, Fig. 3 are the utility model plug, lid other two the embodiment longitudinal diagrams on the thermal bottle bottleneck.

Fig. 4 is the longitudinal diagram of the utility model plug, lid embodiment on the vessel port of safe thermos jar, incubation canteen, refrigerating bottle, thermos cup, insulation jar or the like.

Fig. 5 be with groove structure vertically to cuing open, slice off half after, chock plug side schematic top plan view.

In the concrete structure of Fig. 1 to Fig. 4, this utensil is mainly formed by plug (2) and lid (6) two most of socket disjunctors, and lid (6) is enclosed within plug (2) outside.Have seal cavity (5) on this utensil, have the reflex-reflective material or the device of counter radiation in it, the air pressure in the seal cavity is lower than ambient atmosphere pressure.Thereby hinder conduction, convection current and the radiation of heat energy effectively.Lid on lid (6) and the former various vacuum heat-insulating containers is in moulding, structure, and function aspects is similar, and caping is all arranged, and lid surrounding edge wall all has and shell of tank bonded assembly screw socket or the corresponding bindiny mechanism of socket or spinner or the like in limit wall bottom.And fill in (2) is hollow, can directly and cover (6) socket, also can be connected with lid with groove structure (4) disjunctor again.Plug (2) and groove structure (4) constitute the piston part.Shown in figure one, figure four, with the plug face of vessel port (1) contact and groove trough wall surface on the outstanding tabula (3) of several elastic rings that is similar to parallel or same trend with the vessel port transverse plane is arranged.Plug (2) plug face all around, the cell wall of groove structure (4) all with vessel port around wall almost parallel, thereby this utensil on container except being earlier the plug bonnet, filling in the degree of depth of vessel port can regulate, after all filling in, for screw socket or screw fastening type plug, lid, can it be connected on the cell therefor shell swivelling cover subdivision securely; For eye-splice-type or socket type plug, lid, all fill in stopper, even also lid eye-splice or socket are in the corresponding bindiny mechanism of shell of tank.As shown in Figure 1, the piston part of the utility model utensil is for the trapezoidal cork of thermal bottle, and the area at the position of jam-pack vessel port is 3 to 4 times of cork.When chock plug was filled in vessel port, the periphery of vessel port (1) also was filled in groove, becomes two-way clogging because groove structure! Thereby both clogged material in the vessel port, and vessel port is wrapped in this plug, the lid, hinder the heat transmission on the vessel port (1) effectively.And the outstanding tabula of annular makes this utensil and vessel port (1) resilient tight fit, and is airtight to reach; Owing to have elasticity, screw or fastening again, promptly under chock plug (2) and groove position (4) the jam-pack vessel port state, if excessive pressure is arranged, can release in the container by tabula at this utensil; Otherwise, then can leak into.So, also solve the problem of jumping plug, exploding courage, can not pulling out stopper.These tabulas have not only reduced the heat conduction contact surface of this utensil and vessel port, and make the liquid of vessel port periphery of inner wall or gas tabula in cell from level to level, hinder the convection current of heat.

Lid (6) portion of this plug, lid and plug (2) portion can be respectively with plastics or rubber-plastics material compactings, and inside has reinforced rib or makes plug, lid disjunctor have very firm structure after making.It is for example silver-plated or coat reflecting coating to plate reflective metal layer on the inner face of plug, lid, or load onto for example aluminium foil or the like of reflecting metal paper tinsel, to fill in then, cover hot pressing and connect as one, air themperature when making hot pressing is higher as much as possible, acrylic plastering for example, can be up to 160 degree Celsius, and make the cooling rapidly of part surface, so that profile and firm degree adhere to specification.Like this, the air pressure in the middle seal cavity (5) that forms at this plug, when lid reaches 100, still is lower than ambient atmosphere pressure.Thereby when on cool-bags such as thermal bottle, using, can hinder the conduction and the convection current of heat energy effectively.
