All of these designs are way too "dainty" What I do is to transfer the oil to a bottle with a good sprayer. (i.e. I can't believe it's not butter container) Put a TRIGGER on the cap to spray or flow (like a kitchen cleaner sprayer) This will give a nice even coat of spray over the food. When I bake chicken breast or fish fillets, the tops don't dry out in the oven. Also, with a trigger spray container or cap, you don't have to be concerned about vacuum draw or clogging. Get the job done with a trigger spraying device. It's quick and easy! -Jack Fleming

It will gum up quickly.

This looks like the only one of the designs that would not create a mess.

I think this would work the best.

Terrible and complicated

Hi, I have a comment that applies to the fundamentals of this project, so I'll paste it on each idea. I'm sorry to do this but unfortunately, there's no other way.

Any comestible oil, air and plastic do not (actually, never) go well together - contact with oxygen triggers a chemical reaction, some of the compounds of the plastic may be absorbed by the oil - it gets rancid. And when (not if) that happens, unless you can thoroughly clean the device, there's not much you can do but throw it away.

That is why good quality oils are always sold in glass or metal containers. Even then, you need to wash the containers from time to time if you don't want your oil to get rancid.

On all the projects presented there is, if not a difficulty, an impossibility to clean the devices and that's a big design flaw.

- material should be glass or metal - not plastic
- the device has to be "air tight" when not measuring
- we have to be able to clean "inside" from time to time (and just pumping soap doesn't cut it, it has to soak as well for a few hours)

Lock In Amount could work if,
- it has a cap
- it's made of metal (even the plunger)
- instead of choosing between 1 TSP or 1 TBS, it were between "continuous flow" (Eric Gibbons is right!) and a TBS - the open position would help to clean it

I am sure that there would be problems with priming the pump. What I mean is that the measurement would not be accurate until all the air is expelled from the pump and I think issue would occur every time the bottle is left standing. So the first few pumps would have to be wasted

2nd place for me!
I like the other pump option better. This idea is pretty good too but the other one seems easier to use. Great job in coming up with a different look for this too! This is very creative.

Too restrictive I think. What if you just want to pour some over a salad or in a pan...

This one is a little too confusing for me, particularly because of a lack of explanation of how the "selected" amount is actually chosen/limited, I see a few possible flaws with it.
