Description
Technical Field
The utility model relates to the field of daily-life household utensils containers, in particular to a flanging sealed double-layer heat-preservation cup cover.
Background
The vacuum cup is a common drinking tool in daily life, generally adopts a container made of ceramic or stainless steel and a vacuum heat insulation layer for containing water, is provided with a cup cover at the top, is tightly sealed, and is carried; the vacuum heat insulation layer can delay the heat exchange between the liquid such as water and the like in the vacuum heat insulation layer and the air so as to achieve the purpose of heat insulation. However, the traditional thermos cup has the limitations of cost and process, the double-layer vacuum structure is only realized on the cup body, and the cup cover is often of a single-layer structure. When the heat is radiated upwards, the cup cover does not preserve heat, so that the heat preservation effect of the whole vacuum cup is greatly influenced; some thermos cups are in order to solve the heat preservation problem, set up sandwich structure on the bowl cover, place the foam heat preservation layer in the intermediate layer, but its structure is complicated, and the heat preservation effect is unsatisfactory. Meanwhile, the traditional upper cover plastic is in direct contact with water in the cup by adopting a PC or PE material, so that peculiar smell is generated, the drinking water quality is reduced, and toxic substances can be generated when high temperature in the cup is met.
Through improving, three kinds of double-deck heat preservation bowl cover structures have appeared on the market, the first kind is the plastic base member of adopting opaque material preparation, the plastic base member material of bowl cover is various, the big situation based on environmental protection and resource recycle more adds the inherent demand of trade company's reduce cost, it has been very common to adopt the reprocessing of recovery plastics to make the bowl cover base member, nevertheless is nontoxic tasteless plastics, it also has the decomposition of molecule or the ageing of plastics etc. under the high temperature direct contact of boiling water for a long time, this has just formed certain health risk.
The second heat preservation bowl cover structure summarizes and concludes a structure that produces after having concluded above-mentioned structural defect, adopts double-deck metal lid body structure, and toxicity and the fragile asynchronous scheduling problem that is heated of plastics have been avoided to this kind of structure, have also solved composite construction's disjointed, the easy fungus defect of living of seam, have both guaranteed the heat preservation effect of bowl cover, possess good structural strength again, but still have certain defect along with long-term the use: in practical use, a structure of a stainless steel inner cover and other alloy outer covers or a double-layer stainless steel structure is generally adopted, in the prior art, a double-layer vacuum vessel is manufactured by combining titanium and stainless steel, however, because titanium has high strength, small density, good mechanical property, toughness and corrosion resistance, in practical use, the titanium is mostly combined in the modes of screw locking, gluing, riveting and the like, the mechanical combination mode can cause a gap between the two metals, and energy is mostly transmitted through screws or rivets, so that the energy transmission distribution is uneven; the gluing has temperature resistance, and the bonding firmness and airtightness are affected by embrittlement or softening phenomena usually caused by the temperature exceeding 180 ℃. Titanium and stainless steel belong to the dissimilar metal material, and both nature differences are too big to the unable alloyed combination effect that reaches of mechanical bonding mode, can make two kinds of metals produce the clearance, influence the firm in connection nature and the gas tightness of structure. The double-layer stainless steel is connected and sealed by fusion welding, the solder cannot meet the requirement of food grade, other metal elements are easy to separate out and generate peculiar smell, and hidden danger is caused to human bodies; the edge of the cup cover frequently rubs with the mouth of the cup body for a long time, so that abnormal friction sound exists, surface scratches can occur, metal chips fall off, and the cup cover is still harmful to the human body.
The third heat-preservation cup cover structure is a composite sandwich structure formed by plastic and stainless steel, a stainless steel outer cover is wrapped outside a plastic cover body or a stainless steel lining layer is arranged in the plastic cover, plastic parts PP, PC or PES plastic are wrapped outside the plastic cover body, and the heat-preservation cup cover of the structure solves the problems of heat preservation and non-toxicity in the using process and has the following problems: the two parts need to be adhered by glue which is harmful to human body; the thermal deformation coefficients of the two parts are inconsistent and are easy to disjoint, and the joint between the two parts is easy to feed water and ash when drinking water or cleaning the cup cover, so that bacteria are bred for a long time, and the heat preservation effect of the cup cover is also influenced.
