"Flask of the Dragons Breath" Magic Item - how it works ?

[Istar]

Okay just wondering if they had some errata to this to clear it up.
But as it stood when first came out.

A Minor Action to consume it.
And then anytime during the next encounter you could "Breathe" out a mini dragon breath.

Didnt state if this was a standard action, minor action, free action, to "Breathe".
And Dragon Born do it as a minor.

So no stating then we assume this is going to be a no action, just breathe fire ?

The entry in the Compendium says it's a minor action to both drink it and to use the dragon breathing power.
