The main points of buying a sports bottle can be summarized in twelve words: durable, safe and reliable, and convenient for insurance.
1. The key to "sturdy and durable" is the pot body material and wall thickness
The material of the sports bottle is pure aluminum. As a large country of aluminum products, China has a complete range of products. In terms of material selection, each manufacturer has different materials. Many domestic water bottle brands use pure aluminum with a purity of 99.5%, but the actual situation is not the case. Even most manufacturers use recycled aluminum.
Another factor is the wall thickness of the water bottle, the wall thickness of a general sports bottle is 0.7mm. Since it is difficult for ordinary consumers to distinguish the wall thickness of sports bottles, some manufacturers will speculatively reduce the wall thickness of the kettle to save materials in order to reduce costs. Some manufacturers even reduce the wall thickness to 0.5mm. An intuitive feeling for judging the thickness of the kettle wall is that if you compare it in your hand, the weight of the kettle with a thinner wall will be lighter.
If the sports bottle is made of low-purity aluminum, or the wall thickness is cut corners, it is easy to dent, break or even burst due to collision or fall during use. Generally, the higher the purity of the aluminum material used for sports bottles and the standard wall thickness, the better the strength and toughness of the sports bottle, and the stronger the resistance to collision and impact. Of course, the better the quality, the higher the cost and price.
2. The key to "safety and reliability" is the inner coating of the sports bottle
As we all know, excessive intake of aluminum will cause greater harm to human health. The inner coating of the sports bottle solves the isolation problem: separate the water, juice, milk, coffee and other beverages in the sports bottle from the aluminum body. Come.
The composition of the inner coating of the sports bottle is more than 20% resin, about 1% additives, and the rest are solvents. The quality of the sports bottle is the most important determinant of whether it is safe and reliable. The first is whether the inner coating material itself is safe and will not cause harm to human health. In addition, the spraying quality of the inner coating inside the kettle is uniform and sticky. The attachment is firm and reaches the necessary thickness to ensure the reliability of the isolation between the beverage and the aluminum pot body.
Under the pressure of fierce export competition, in order to reduce costs and increase competitiveness, most domestic manufacturers choose low-priced coating materials, and are limited in scale and strength, and its equipment and technology are difficult to guarantee the inner coating of sports bottles. Spraying quality.
The inner coating of sports bottles must meet food-grade hygiene requirements, but due to lack of supervision and testing, domestic sports bottle products, except for a few large-scale manufacturers, almost all of the inner coatings flooding the market with cheap products exist Problems of varying degrees.
Generally, the lid of a sports bottle is composed of a lid and a gasket. In the process of use, the quality of the general sports bottle is not too hard, the gasket will stick to the spout part due to the tightness of the screw and be squeezed for a long time, cold or hot temperature factors, and even detach from the lid, causing trouble in use , Sometimes it will be lost and affect the reuse of the kettle.
A good sports bottle uses two-shot injection technology to directly integrate the gasket and the lid, which not only achieves a good sealing effect, but also fundamentally eliminates the possibility of separation.
The tightness of the spout depends on the degree of fit between the lid and the threads of the spout. If the degree of anastomosis is not high enough, water leakage may occur during normal use, which will bring a lot of inconvenience to use. Many people must have had some unpleasant experiences in this regard.
In addition, almost all sports water bottle spout threads have sharp edges. Although there are not many scratches on fingers and lips, they still happen occasionally. A good sports bottle will have a more user-friendly processing and treatment, which is to make the edge of the thread into an arc, so as to completely eliminate the possibility of scratching your fingers and lips even with a small probability.
