Description
Technical field
The utility model relates to a kind of thermos cup, especially a kind of double-layer vacuum insulation glass refills formula thermos cup with sealing device.
Background technology
The glass refills of double-layer vacuum insulation at present formula thermos cup generally is made up of cup, glass liner, sealing ring and bowl cover, and glass liner is built in the cup.Because the processing technology defective of double-layer vacuum insulation glass refills, the out-of-shape of glass liner, the common out-of-flatness of bottle bag edge, realize that thermos cup is water-tight, usually adopt following two kinds of sealing means: in the built-in cup of a kind of glass liner, the glass liner upper exposed is outside cup, both are in rim of a cup portion plastic seal ring sealing and fixing, plastic seal ring is a hard material, can only play fixation, still can not seal the space of glass liner and cup, having water penetrates in the cup, and, because the glass refills notch portion is exposed at the cup outside, than being easier to fragmentation.Another way is in the whole built-in cups of glass liner, one U-lag is arranged at cup top, top edge and cup contact position cushioning one U-shaped rubber ring at glass liner, the cup base holds the glass liner lower curtate, the glass liner top edge is squeezed in the U-shaped rubber ring in the U-lag of cup top, realize the sealing of out-of-flatness glass liner top edge, need the bigger power of base to realize, and the position that requires base to hold can make glass liner top edge, U-shaped rubber ring and cup three fit just and realize sealing, because the out-of-flatness shape of glass liner can make the difficulty that realizes that sealing becomes.The bowl cover place of dual mode does not all have sealing device, all drainage can occur when thermos cup is arbitrarily placed.
The utility model content
The purpose of this utility model is to provide a kind of double-layer vacuum insulation glass refills formula thermos cup with sealing device, solves glass liner and is exposed to outer and glass liner and cup sealing problem.
Another purpose of the present utility model is to provide a kind of double-layer heat insulation glass refills formula thermos cup with sealing device, further solves the sealing problem between bowl cover and the cup.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of double-layer vacuum insulation glass refills formula thermos cup with sealing device is made up of cup, bowl cover, glass liner, sealing device, and cup is made up of body, loam cake and cup base; Described body top is provided with connecting thread; Be equipped with connecting thread inside and outside the described loam cake, be provided with two boss between internal thread and the top rim of a cup; Glass liner is built in the body, and its top is with a rubber ring; Loam cake is threaded with body, makes the top edge of glass liner hold first boss at rim of a cup just, and rubber ring is squeezed in second boss.
Also have a sealing gasket between the rim of a cup of described cup and the bowl cover, the sealing pad is fixed on the projection of central authorities in the bowl cover.
The inside upper part of above-mentioned body becomes italic.
The surface of above-mentioned sealing gasket is provided with burr.
Above-mentioned burr is a screw-like.
The sealing device of cup provided by the utility model and glass liner, glass liner can be hidden in the loam cake of cup, loam cake utilizes fixedly rubber ring of screw thread, just make the top edge of glass liner hold first boss at rim of a cup, rubber ring is squeezed in second boss, even glass liner shape irregularity, because of rubber ring is a flexible material, can be according to the suffered change shape of pressure, and the inboard one-tenth of cup italic, seal up the space of glass liner and cup after helping rubber ring and being extruded fully, avoid the water in the cup to penetrate in the space of cup, and, hold glass refills on dynamics and position and do not require at the cup base, simultaneously, also solved glass liner and exposed problem, made the easier solution of sealing problem of cup and glass liner; In addition, in utility model, the sealing of bowl cover and cup has been adopted to convex with sealing gasket in the bowl cover, makes better tightness.Realized sealing, the thermos cup temperature retention time increases more than the twice, can reach tens hours usually.
