not sure if this is exactly what you mean but as an example:
Let a,b be sets.
Maybe you could call these things with the * operation "boxes". And the binary aggregation operator (I guess you're thinking of operators that are analogous to the union operator for sets?) is kind of like the act of putting the second "box" inside the first.
Perhaps "objects" could be thought of like this. To "union" two objects you could put the second inside the first. (As opposed to creating a new third object that contained the first two).
