This site will give you a little more detail on
the obviousness rejection.
First let’s look at what has been allowed.
The cup version is OK.

But our most-likely-to-be-used versions were rejected as being
obvious. The dose by weight dropper is where it all began.

Our final permutation is the BSA syringe. (This one is still
in limbo, in CIP 7 which has not been examined yet.)
