1Standard on average improves about 10 ℃.It by cork 1, mould spacer ring 2 and mould bowl cover 3 (perhaps by moulding matrix 12, mould substrate cover 13 and moulding handle 14, mould spacer ring 2,2 ', mould bowl cover 3) constitute.
Description
The present invention relates to the plug for vacuum bottle of vacuum flask, particularly a kind of efficient thermos plug.Past people is placed on the emphasis point that improves the vacuum flask thermal property all the time and improves glass liner qualitatively, as gas clean-up, improve silver coating, change prescription etc., 1 ℃ of the every raising of result all will be paid expensive cost, hardly realize with the supporting bottle stopper of glass liner also be a key factor that influences thermal property.Because vacuum flask bottleneck shape differs, scale error is bigger, ordinary bottle plug matches with it and is difficult to form sealing condition, so that there are heat convection and bigger heat conduction inside and outside the glass liner, thereby extraneoas loss a part of heat, so with the vacuum flask of ordinary bottle plug store boiling water after 24 hours reality be difficult to make tea, make coffee etc.
The objective of the invention is to improve the tightness of bottle stopper and bottleneck, thereby reach the reduction thermal loss, prolong the effect of temperature retention time by the shape and the structure of redesign bottle stopper.
The present invention finishes in the following manner: increase the plastic sealing ring that several can thermal deformation, stop the inside and outside thermal convection current of glass liner, change heat conduction gradient.The present invention of Zhi Zuoing can be with the day warming index present relatively international iso standard and the light industry QB promulgated by the ministries or commissions of the Central Government of vacuum flask in such a way, and 8 ,-8, standard on average improves about 10 ℃.
Below in conjunction with accompanying drawing two embodiment of the present invention are elaborated.
Accompanying drawing 1 is plastics of the present invention-cork combined shaped and structure chart.
Accompanying drawing 2 is all-plastic combined shaped of the present invention and structure chart.
Embodiment one:
See Fig. 1, the present invention is by cork, and 1, its height is moulded spacer ring 2 and is moulded bowl cover 3 and constitute between 15～50 millimeters.Wherein cork 1 has a funnel-form through hole 11, moulding spacer ring 2 is the hub-like of an end closure, and there is soft ring 8 together in its outer garden on week, and there is the β angle of a chamfering between 15～90 ° at its edge, there is a through hole 9 at the middle part, moulds spacer ring 2 single injection-moldeds.Moulding bowl cover 3 has bowl-shape ring 6, its inclined angle alpha between 15 °-75 °, wheel hub 5 and garden post 10 single injection-moldeds.
Pass the funnel-form through hole 11 that passes cork 1 behind the through hole 9 of moulding spacer ring 2 again with moulding garden post 10 on the bowl cover 3, the 10 top moulding of hot pressing garden post can be in aggregates cork 1, spacer ring 2 and 3 hot rivetings of bowl cover, and 4,7 are respectively the air heat-insulation layer that rivet hot forms.
Embodiment two: the component structure of present embodiment and embodiment one is basic identical.
See Fig. 2, the present invention by mould spacer ring 2,2 ', mould bowl cover 3, mould matrix 12, mould substrate cover 13 and mould handle 14 and form, and mould spacer ring 2,2 ' on have respectively together soft ring 8,8 ', with mould garden post 10 on the bowl cover 3 pass mould spacer ring 2,2 ', mould matrix 12, mould substrate cover 13 and mould the garden cylindrical hole of handle and hot riveting is in aggregates.4,7,7 ', 15 be respectively the air heat-insulation layer that forms after the hot riveting.The outer garden of moulding matrix 12 is of a size of 30～150 millimeters of φ, 25～100 millimeters of conical section upper end diameter φ.
See Fig. 1, Fig. 2, hand cork 1 upper end or mould handle 14, the present invention is vertically inserted in the insulation bottleneck, at this moment bowl-shape ring 6, soft ring 8(or soft ring 8.8 ') can be heated and follow the bottleneck inner wall deformation, thereby with cork 1 or mould matrix 12 and form three or four road sealing rings, strengthened tightness, changed hot conduction gradient, realize the reduction thermal loss, reached the purpose that prolongs temperature retention time.
The spacer ring 2 of moulding of the present invention is moulded bowl cover 3, moulds matrix 12 and moulds substrate cover 13 usefulness polyethylene or other non-toxic thermoplastic plastic's injection molded.
The present invention has the reduction thermal loss, prolongs the effect of temperature retention time.
