Claim Text:
1. A container for being interlockingly stackable and self-sealing, comprising: a) a body; b) an upper interlock component; c) a lower interlock component; and d) a circumferential shoulder; wherein said upper interlock component extends outwardly from said body; wherein said lower interlock component extends inwardly from said body; and wherein said lower interlock component replaceably receives said upper interlock component of a next lower container so as to allow said container to be interlockingly stacked and self-sealed; wherein said body has a lowermost end; wherein said body has a circumferential wall; wherein said lowermost end of said body has a recess; wherein said recess of said lowermost end of said body is partially defined by a lowermost circumferential ring; wherein said lowermost circumferential ring of said recess of said lowermost end of said body is spaced radially inwardly and concentrically from said circumferential wall of said body so as to form an open-topped circumferential ring therebetween that has a generally U-shaped cross section having a pair of radially spaced-apart circumferential walls defining an open-topped gap therebetween and a curved lowermost portion that connects said pair of radially spaced-apart circumferential walls to each other and which is disposed at said lowermost end of said body; wherein said pair of circumferential walls comprise an inner circumferential wall and an outer circumferential wall; wherein said inner circumferential wall has a straight vertical component; wherein said open topped gap is partially disposed between said straight vertical component and said outer circumferential wall; wherein said lower interlock component is disposed on said straight vertical component; wherein said circumferential shoulder extends upwardly from said upper interlock component; wherein said curved lowermost portion of said open-topped circumferential ring is entirely radially curved, and as such, has no straight portions; wherein said open topped gap has a radial cross section; wherein said open topped gap has an entire circumferential expanse therearound; and wherein said radial cross section of said open topped gap is unchanged along said entire circumferential expanse thereof.
