Sport water bottles have become more popular and environmentally friendly emerging sporting goods. With the rise, development and continuous growth of global outdoor sports, the global sales of sports bottles are expanding year by year.
1. Sports net kettle with filtering function
The portable net kettle is a new sports bottle in the past two years. Its appearance is similar to that of a traditional kettle. However, its internal filter function filter can quickly filter different fresh water such as outdoor river water, stream water and tap water into straight drinking water, which is convenient for outdoor sports conditions. Get safe, safe drinking water anywhere.
2. Ordinary sports bottle
Traditional sports water can only store the drinking water needed for sports.
3. Folding sports bottle
Portable folding kettle, the bottle can be folded after the water is dry, and does not occupy the place.
1. Sports Refers to the kettles used for some more intense sports occasions, such as running, climbing, etc., which is characterized by more emphasis on the quality and sealing function of the buckle.
Silicone folding water bottle
Silicone folding water bottle
2, outdoor use refers to the use of hiking, picnic, tourism and other occasions, characterized by more lightweight, hang buckle multiple forms.
3, students can be said to be similar to the outdoor use of the kettle, but because it is used by children, in the design and production is different from the professional kettle, students use sports water bottles more convenient and easy to use, such as It is possible to use a rotary cover instead of a plug to open the cover.
1, plastic sports bottle
Advantages of plastic: light, heat-conducting, slow-filling hot water is not hot, big mouth, cheap. Disadvantages: not wear-resistant, unqualified materials will have harmful substances.
2, stainless steel sports bottle
Stainless steel advantages: strong, no harmful substances are harmless to people, heat resistance. Disadvantages: The heat conduction of the single layer is fast and not wearable. The double-layer stainless steel container requires high processing precision, and the joint is prone to water leakage and bacteria.
3, aluminum sports bottle
Advantages of aluminum products: light and stylish. Disadvantages: The heat conduction is too fast, the hot water can't be taken, and the cold water can't be taken. Aluminum products are too soft to bump into the pits, and excessive aluminum intake can cause harm to the human body.
4. Silicone sports bottle
Advantages of silica gel: it can be folded, easy to carry, light, heat-conducting, slow-filling hot water is not hot, big mouth, heat-resistant, no harmful substances are harmless to people, resistant to falling.
Disadvantages: The material is too soft, and it takes two hands to drink water when there is less water.
People who have had experience in field activities are probably impressed by the dependence of outdoor sports on water. Water is sufficient to ensure the quality of outdoor life and the most basic conditions for physical health. Simply relying on mountains to eat mountains and relying on water to eat water can not make you solve thirst at any time, but will consume more energy and bring health hazards. So in any book that introduces outdoor life, how to acquire, transport, preserve and properly distribute the use of limited drinking water is an important chapter. Because in many cases there is no water to drink is the key to the success or failure of an event.
When it comes to kettles, you can't help but mention SIGG.
SIGG is the world's first brand of sports bottle in the world. It is made in Switzerland. The processing technology of this kind of kettle is very special. It is extruded and stretched by a piece of aluminum (aerospace aluminum alloy, ultra-light, strong, not cracked). The process is made.
This kettle has a few special features:
First, the kettle has a special round rib at the bottom to prevent the kettle from being severely deformed when it falls.
Second, the kettle realizes the non-equal wall processing process, that is, the wall of the kettle body is the thinnest and gradually increases the thickness to the mouth of the kettle and the bottom of the kettle, so that not only can the weight of the kettle itself be reduced, but also the rigidity is stronger.
Third, another special point in its coating processing technology, SIGG company uses the hot melt spraying method, that is, the coating material is heated and melted and then sprayed on the inner wall of the kettle by electrostatic spraying method, so there is no taste. The coating on the inside of SIGG is not only hygienic and durable, but also can be used for carbonated and fruit acid beverages (because these two beverages are very easy to corrode the kettle), so other kettles can't promise.
The main points of choosing a sports bottle can be summarized into twelve words: durable, safe, reliable and convenient.
1. The key to “sturdy and durable” is the body material and wall thickness.
The material of the sports bottle is pure aluminum. As a big country of aluminum products, China has a complete range of products. In terms of material selection, each manufacturer has its own characteristics. Many domestic kettle 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 kettle, which is generally 0.7 mm thick. Since it is difficult for the average consumer to distinguish the wall thickness of the sports bottle, some manufacturers will opportunistically reduce the thickness of the kettle to save material in order to reduce the cost. Some manufacturers even reduce the wall thickness to 0.5 mm. An intuitive feeling of judging the thickness of the kettle pot wall is that if the contrast is in the hand, the weight of the kettle that thins the wall thickness will be lighter.
If the sports bottle is made of aluminum with low purity or thick wall thickness, it is easy to sag, smash or even burst due to collision or falling. Generally, the higher the purity of the aluminum sports bottle, the higher the wall thickness, the better the strength and toughness of the sports bottle, and the stronger the ability to resist collision and impact. Of course, the better the quality, the higher the cost and price.
2, the key to "safe and reliable" 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 layer of the sports bottle solves the problem of isolation: the water, juice, milk, coffee and other drinks in the sports bottle are separated from the aluminum body. Come.
The composition of the inner layer of the kettle sports bottle is more than 20% resin, about 1% additive, and the rest are solvents. The quality of the sports bottle is good or bad. The most important determinant is whether the inner coating material itself is safe and will not cause harm to human health. In addition, whether the inner coating is sprayed on the inside of the kettle is uniform or sticky. It is firmly attached and reaches the necessary thickness to ensure the reliability of the separation of the beverage from the aluminum body.
Under the pressure of fierce export competition, in order to reduce costs and increase competitiveness, most domestic manufacturers currently use low-cost coating materials, and limited by scale and strength, it is difficult to ensure the inner coating of sports bottles by equipment and technology. The quality of the spray.
The inner coating of the sports bottle must meet the food-grade hygiene requirements, but due to the lack of supervision and testing, the current domestic sports bottle products, in addition to several large-scale manufacturers, are almost all of the inner coatings that are flooding the market with cheap products. There are different levels of problems.
The lid of a general sports bottle is composed of a lid and a washer. In the course of use, the general sports bottle is not too hard because of the quality. The gasket will stick to the spout part because of the tight pressing time, cold or hot temperature factor, and even get out of the lid, which brings troubles. Sometimes it will be lost and affect the reuse of the kettle.
The good sports bottle uses the double injection molding technology to directly integrate the gasket and the lid, which achieves a good sealing effect and fundamentally eliminates the possibility of detachment.
The tightness of the spout portion depends on the degree of fit between the lid and the spout thread. If the degree of coincidence is not high enough, there will be leakage of water during normal use, which will bring a lot of inconvenience to the use. In this regard, many people have had some unpleasant experiences.
In addition, almost all the edges of the sports bottle spout thread are sharp, although the situation of scratching the fingers and lips is not a lot, but it happens occasionally. A good sports bottle will have a more humanized processing and treatment, which is to make the edge of the thread curved, thus completely eliminating the possibility of scratching the fingers and lips even with a minimum probability.
