I've been carrying a Camel-Bak sport bottle with me to and from work
every day for the past 2 months because I'm cutting back on my soda
consumption. I've been drinking almost nothing but water this whole
time, and have lost a lot of weight as a result.
The issue I'm attempting to resolve
this idea is the tendency of
the lid of said sport bottle to become inadvertently loosened while
twisting the spout open/closed, and dumping large amounts of the
contents down my shirt when I attempt to take a sip. I don't believe I
can the only person to have had this problem.
So my idea is for a line of sport bottle and Thermos-like products with
lids that have pressure sensors on the underside, and either a spring-
loaded pop-up post or an LED indicator that signals when it is screwed
on all the way. The LED might be be better because it could be used to
turn red when its not sealed, and green when it is. Not sure if there's a
mechanical equivalent for that function. I'm not attached to either
specific method, but the idea of any reliable indicator is what I'm going
||[Ian] yes, but I wonder if your solution could deliver a proportionally stronger
temperature-response signal depending on the variable integrity of the seal?
||Man oh man... Ian, you have my vote, altered temperature sensitivity and all.
||Ya know, I just *knew* someone was going to say that, Ian.
||The sensor should also account for a cover that's screwed on really tightly at an angle.
|| How about a valve system plus pressure sensor that detects whether the bottle can be pressurized?
||I had thought about that, but would make the bottle too bulky.
