Vessel including a unitary or two-part vessel base having an intermediate wall portion, upper and lower wall portions on opposite sides of the intermediate wall portion, and upper and lower seal rims adjacent the respective upper and lower wall portions. The upper and intermediate wall portions define an upper chamber space including at least one upper chamber. The lower and intermediate wall portions define a lower chamber space including at least one lower chamber. The seal rims include edges configured to provide suction when pressed against a flat surface, preferably when these rims are wet. Lids engage with upper and lower lid-receiving portions, respectively, defined by the vessel base to selectively close the upper or lower chamber space. The two-part vessel base has a mating structure to facilitate selective attachment and separation. |
