Ok, the potential scenario is this:
Enemy has portable hole that he carries various things that can jump out and get instant reinforcements.
Can someone using, say a wand of dispel magic, stay invisible and use it to disable the portable hole after it is thrown, but still prior to it being opened and remain invisible?
Assuming that the wand user is able to act between when the hole is opened and when the creatures jump out of it, I'd say yes.

Right. In this case he'd have a readied action for just that event.
That only lasts 1d4 rounds, and needs a dispel check to succeed.
Better to use a Create Pit spell. Most casters who can cast dispel magic ate at least 5th level. At that level, the pit lasts 6 rounds. As an extra-dimensional space, it disallows access to the space in the portable hole.
As a 2nd level spell, it cost less for the caster, and is available sooner. It is also useful on its own. It does not need a dispel check. Instead, the item gets a reflex check, but that is going to be difficult for the hole with its -5 Dex penalty.
Another factor is how long the creatures are in the hole, as there is limited air.

Cevah,
A couple problems off the bat (although I like where you are coming from -- it's a very inventive use of the spell)
1) The AoE of the spell is likely to include the portable hole's prior owner, which would break the invisibility. Secrecy is of utmost importance in this case.
2) The creatures in the hole are undead (shadows/juju zombies, etc), so air isn't much of a concern.
I'd like to simply teleport the unattended object right out of mid-air, but there doesn't seem to be any way of doing that.
"Actions directed at unattended objects do not break the spell." So if the readied action is set up to wait till the hole is unattended then it would not break invisibility.
Alternatively, do you have a bag of holding and an unseen servant? Because you could give the bag of holding to the unseen servant and direct it to drop it into the portable hole.
"If a bag of holding is placed within a portable hole, a rift to the Astral Plane is torn in that place. Both the bag and the cloth are sucked into the void and forever lost."
Since the unseen servant is the one doing the dropping, that wouldn't break invisibility either. And it would really mess up the bad guy's day. The only downside is it also blows up your treasure. But you can't make an omelette without ripping a rift to the Astral Plane and destroying over 20 large in loot, as Quibblegramma used to say.
