In a nutshell, the plastic (called polyethylene terephthalate or PET) used in these bottles contains a potentially carcinogenic element(something called diethylhydroxylamine or DEHA). The bottles are safe for one-time use only; if you must keep them longer, it should be or no more than a few days, a week max, and keep them away from heat as well. Repeated washing and rinsing can cause the plastic to break down and the carcinogens (cancer-causing chemical agents) can leak into the water that YOU are drinking.
Better to invest in water bottles that are really meant for multiple uses.
This is not something we should be skimping on. Those of you with family - do please advise them, especially children.

Although they company might have cautioned us by priting - 'Crush after use', none of them follow it. In India, almost all people use it for ages, say one year.
I myself don't lend my ears to those cautions and I will use them for a long time. Shame on me. I will try my best to change myself now-onwards.
SAFETY & HEALTH: Safety
Plastics: Cancer & Chemicals

Soft plastics are more hazardous than hard plastics. The reason is that soft plastics are chemically unstable – they outgas into the air, whereas hard plastics are chemically inert.
microwave + plastic = carcinogen
an area of controversy!
There is some controversy over this issue of microwaving plastic. Since heat is know to release substances (remember we leach iron into our food from cooking in an iron skillet), I would personally opt on the side of caution. It may just be safer to use tempered glass, Corning Ware, etc.
