Sports bottle is made of aluminum, aluminum products a big country as China, complete range of products, in material selection, various vendors have different, many domestic brands kettle marked a purity of 99.5% pure aluminum, but the reality is not so, most manufacturers are even using recycled aluminum.
Another factor is the wall thickness of the kettle, the kettle wall thickness of the general movement of 0.7mm. Since the average consumer is difficult to distinguish sports bottle wall thickness, and some manufacturers to reduce costs, will be opportunistic in order to save water bottle wall thinning materials, and some manufacturers even thinning wall thickness to 0.5mm. Analyzing wall thickness of a kettle pot intuitive feeling is that if in the hands contrast, thinning the wall thickness will be lighter weight kettle.
If the sports bottle selection is not high purity aluminum, or wall thickness cut corners, in use, it is easy because of collision or falling and depression, wrecked or even burst. Usually the higher purity aluminum sports bottle selection, wall thickness standard, sports bottle the better the strength and toughness, resistance to impact and shock are also stronger. Of course the better the quality, the cost and the price will be increased accordingly.
As we all know, excessive intake of aluminum, harmful to human health hazards caused by relatively large, sports bottle inner coating is to isolate the problem to solve: the movement of water within the kettle, juice, milk, coffee and other beverages with aluminum pot body to isolate Come.
Kettle sports bottle coating composition is more than 20% of the resin, about 1% of the additive, the rest are solvent. Sports bottle good or bad quality, safety and reliability whether most important determinant of whether the first is an inner coating material itself is safe and will not harm to human health, in addition to that in the inner coating spray quality whether spray evenly inside the kettle, sticky firmly attached, and to achieve the necessary thickness, and aluminum beverage to ensure the reliability of the pot body isolation.
Intense competitive pressures forced the export, in order to reduce costs and increase competitiveness, domestic manufacturers use most are inexpensive coating materials, and limited size and strength, its equipment and technology are difficult to ensure within the sports bottle coating coating quality.
Sports bottle inner coating of food grade must meet health requirements, but due to lack of supervision and inspection, domestic sports bottle products, in addition to several large manufacturers, a large number of other cheap products flooding the market, the inner coating almost all There are different degrees of problems.
Usually the lid sports bottle lid and gasket is composed of two parts. During use, the general sports water bottles because of the quality, but hard, because the washer is screwed a long time extrusion, cold or hot temperature factors in the spout tight by the sticky part, even from the lid, bring trouble to use , and sometimes loss of influence of the kettle again.
Good sports bottle using secondary injection technology, the lid gasket and direct integration, both reached a good seal, and from fundamentally eliminate the possibility of detachment.
Sealing spout part depends on the degree of fit between the lid and the spout thread. If the fit is not high enough, there will be during normal use may produce leakage of water seepage phenomenon, and will use the inconvenience, this area must have a lot of people have had some unpleasant experiences.
In addition, almost all of the sports water bottle spout thread edges are sharp, although the case of injuries to fingers and lips are not many, but still occasionally occur. This will be a good sport bottle processing and more humane treatment of the thread is made of curved edges, so eliminate even the possibility of a very small probability of injuries to fingers and lips.
