Does the round storage container seal tightly so liquid does not leak when the lid is closed?

Instead of interlocking tightly to lock, the lid lightly rests on top without packing^[1], and the opening of the body drops smoothly without any inward-rolled gaps^[2]. The official materials provide three structural characteristics for this container: a packing-free silicone lid, a rim without curling, and a cautionary note that liquids may leak^[3][4][5].

The lid material is silicone rubber that withstands from -20℃ to 120℃^[6]. Because there is no encircling rubber packing, it can be washed conveniently without worrying about water stains or mold getting caught in gaps, and the rim of the body also has no rolled curves, so food does not get stuck and it can be wiped clean in every corner^[7]. However, because it is not an airtight product that tightly compresses gaps, if you store soups with lots of broth or juicy foods and tilt it, liquid may seep out^[8]. Rather than carrying it in a bag, it is suitable for storage in the refrigerator to hold dry side dishes or prepped vegetables that you take out and eat often.
