The fresh-keeping box is the fist product of Lock-Lock, and its thermos cup is not as well-known as the fresh-keeping box, but it also occupies a place in the Chinese market. From 2013 to 2017, Lock & Loco's thermos cup products won the championship of China's brand power index for four consecutive years.
 
The thermos cup of Lock and Lock is decent, not as good as the professional insulation ware brand in vacuum technology, the thermal insulation performance is average, the boiling water is in a warm state after 6 hours, the price is mostly between 100 and 200 yuan, and the cost performance is average. The products are mainly rotated to open the lid, the appearance design is more beautiful, most of them are equipped with detachable plastic PP filters, and they are also used as anti-scald drinking outlets.
 
Its one-key opening of the lid thermos cup is the same as the Tiger brand, the safety lock and the opening key are integrated, in addition, the lock and lock is also developing towards lightweight, the LHC3220 capacity of the one-key lid is 500mL, and the net weight of 230g is difficult to compare with the Tiger, but it is still lighter than the general thermos cup. Durability is also a problem with Lock & Lock, and the bouncing lid of the one-button open cup is easy to damage, so it is more recommended to choose the Lock & Lock Lock screw cap cup.
 
Lock's Black Wave series of wave-like undulating cups have a unique shape, and have also launched a top-pressed water-type coffee cup shaped thermos cup and a one-button pop-up lid cup, but the product design pays too much attention to the shape and the insulation effect is average.
 
LHC1435 is a children's thermos cup launched by Lock and Lock, the appearance is similar to Tiger's cartoon animal thermos cup, the price of 182 yuan is much cheaper, but the overall performance is worse than Tiger. This thermos cup is also equipped with two kinds of lids, which can be drunk directly with a straw cup, and can be replaced with an inner cup lid if you want to ensure the heat preservation effect.
