I first encountered Lock & Lock through the baunan (food container) of an officemate. I noted the cover's appendages on the sides and she told me those were to keep the baunan spill-proof, even if you turn it over. When I asked, she told me she got it from Lock & Lock.
It would take me much later to buy a baunan, but I was fascinated by the spill-proof feature in general. At that time our family was juicing fruits and vegetables and putting them in the freezer. I read in a book that their containers should be kept airtight to preserve the nutrients.
One day, while I was walking around ATC, I stumbled upon Lock & Lock, and many products were on sale. I immediately bought spill-proof plastic bottles for our fruit and vegetable juices. I remember them costing less than P150 each. And, for less than P200, I also bought a big water bottle for myself which I could bring with me to the office - later, I used it on my travels.
I found out from a sales staff that they use high-grade plastic, and the plastic in the water bottles I bought was BPA-free, therefore environment-friendly and not harmful to the health.
There's some kind of rubber lining in the bottle and baunan covers, and as long as this is intact, I believe the container will remain spill-proof. The rubber came off my travel water bottle after some years, and it was no longer spill-proof. read more
