1. A reconfigurable container-closure system that comprises:
a first container (10) that has a first reservoir (10e) with a first flowable product (20) located therein;
a second container (110);
a first closure (12) that is able to form a fluid tight seal with the first container (10) and with the second container (110);
a second closure (112) that is sized to engage the second container (110), as well as form a fluid tight seal with the first container (10);
a second reservoir (114e) removably attached to the second closure (112) and having a second flowable product (120) located therein;
wherein:
when the second closure (112) forms a fluid tight seal with the first container (10), then the second reservoir is opened; and
when the second closure (112) is removed from the first container (10), then the second reservoir (114e) detaches from the second closure and remains attached to the first container.
