As a daily necessities, stainless steel cups can be seen in supermarkets or small commodity stores, and are popular. Stainless steel cups are actually divided into many categories. The following editor will introduce the classification, advantages and disadvantages of stainless steel cups, hoping to help everyone.
1. Bachelor Cup
Straight tube shape, the lower part of the appearance is small, the top is slightly larger, the cover is smooth, the cover is convex when reversed, the cover is about 4-6cm thick, and there is a deep groove in the cover. , is conducive to heat resistance, so the thermal insulation performance is better, up to 8-10 hours in place.
The disadvantage is that it is difficult to clean the inside of the cover, and it is easy to produce scale and breed bacteria, which is not conducive to hygiene. The common capacity of bachelor cup is 350ml-500ml.
Second, the bullet
The appearance is elongated and the upper end is arc-shaped. The whole looks like a bullet. Unscrew the lid. The lid can be used as a mouth cup. There is a plug inside for switching the water. The heat function is better than the bachelor cup, which can reach more than 10 hours.
Disadvantages: The bullets are low-priced thermos cups, made in China. Almost none of them use food-grade 304 stainless steel. They are all 201 and 202 steels. What’s more, they use fake 200 series stainless steel. The hygiene problems are serious and heavy metals are used. Exceed the standard, lead exceeds the standard, other materials are also used materials, and the switch water plug is difficult to remove and wash, it is more likely to produce scale, breed bacteria and odor, and the hygiene is not up to standard.
Most of the consumers who use bullet thermos cups are people who have no concept of consumption of thermos cups. They only know that they can keep warm and the price is good.
Three, straight cup
As the name suggests, it is a straight tube with the same size up and down. Except for the shape, the difference from the bachelor cup is that the inner cover does not have a thick plug, which is normally concave. The material used is better, using food grade 304 steel, and some plastic parts also use food grade PC material. For example, the Jinyi vacuum flask series are made of food-grade 304 steel and food-grade PC materials, so the hygiene is more guaranteed.
Disadvantages: The holding time is not as long as the bachelor cup and the bullet, and the holding time is slightly shorter by 1-2 hours, about 7-9 hours to the standard temperature.
4. Mug
It is suitable for use in fixed places, or work places, or families, and units. Similar to a straight cup, but with an extra handle, it is more convenient and comfortable to use, but it is not suitable for carrying out. Compared with ordinary cups, the cup has a large opening and is comfortable to drink water, but it dissipates heat faster, so the heat preservation time is usually a little shorter than that of a straight cup. The common capacity is 350-500ml.
5. Function Cup
It refers to a thermos cup with certain functions, such as magnetization function, structural patent function, or energy weak alkalization, far infrared, nanometer, small molecular group, antibacterial and other energy health function cups. This type of cup is a matter of opinion, but it is good to choose some powerful production factories and brands with quality inspection reports from national departments.
Six, travel pot
It is also called a wide-mouth pot, which has a large capacity. The common low capacity is 750ml, and the large one is 2000ml or more. It has an elastic handle and a strap, which is convenient for many people to share when going out. Unscrew the lid, the lid can be used as a mouth cup, there is a plug inside for switching the water, the height is about 7cm, and part of the plug depth is in the cup body, so the heat resistance performance is good, which is more conducive to heat preservation. With the same structure, the larger the capacity, the longer the heat preservation time, and the heat preservation performance with good structure and large capacity can reach more than 20 hours.
The disadvantage is that it is bulky and inconvenient to carry. Women are more opinionated, so it is more suitable for men who like to do heavy work.
There are also many styles of travel pots. It is necessary to consider whether the material is food-grade 304 stainless steel, and whether the structure is easy to clean and other hygienic issues.
Seven, the kettle
Also known as coffee pot, commonly known as kettle. Stainless steel double-layer vacuum, large capacity, different from the travel pot in that the handle is fixed, the bottom is large and the mouth is small, the belly can accommodate, the bottle mouth opens and closes the water stopper, there is a button or button handle, press down to get the water, the thermal insulation cup Excellent. It is suitable to be fixed in the family or unit, and it is not conducive to carry it out. When purchasing, consider good material, no water leakage, fine workmanship and easy cleaning.
Stainless steel thermos cups are not suitable for making tea and coffee. Because the tea leaves are soaked in warm water in a thermos cup for a long time, just like a mild fried egg, the tea polyphenols, tannins and other substances contained in the tea leaves will be leached out in large quantities. In addition, because the water in the thermos cup will always maintain a high water temperature, the aromatic oil in the tea will volatilize quickly, which also reduces the fragrance of the tea.
