COMBINING MAGICAL EFFECTS (PHB pg 205)

The effects of different spells add together while the durations of those spells overlap. The effects of the same spell cast multiple times don’t combine, however. Instead, the most potent effect—such as the highest bonus—from those castings applies while their durations overlap.

For example, if two clerics cast bless on the same target, that character gains the spell’s benefit only once; he or she doesn’t get to roll two bonus dice.

The second casting of the spell on the chest would replace the first or do nothing, depending on the characters doing the casting and, quite possibly, DM fiat.
