A container ensemble for food packaging comprising a substantially planar lid member formed of a polymeric material which has a plurality of substantially planar lids which are integrally formed and separably joined to each other, each of the lids including a sealing channel around its perimeter and a skirt extending outwardly therefrom. The lid member is provided with tearable portions to facilitate separation. The other component of the ensemble is a cup member formed of a polymeric material defining a plurality of cups which are integrally formed and also separably joined to each other, the cups including a bottom, a sidewall, and a brim about an upper opening of each cup. Each cup has a skirt extending outwardly from its brim provided with tearable portions to facilitate separation. The sealing channels of the lids of the lid member are adapted to mate with the brims of the cups to provide a plurality of separably joined sealed containers when the lid member and cup member are joined in sealing engagement; the ensemble being thereby adapted for sequentially: (i) receiving serving portions of food in a plurality of cups; (ii) lidding the cups to provide sealed containers containing individual portions; (iii) separating the sealed containers; and (iv) distributing the portions.

What is claimed is: 1. A container ensemble, comprising: an array comprising a plurality of substantially planar lids, each lid having a sealing channel and a skirt extending outwardly therefrom and completely thereabout, wherein the lids are integrally formed and tearably joined to each other, and an array comprising a plurality of cups, each cup having a brim and a skirt extending outwardly therefrom, wherein the cups are integrally formed and tearably joined to each other; wherein the sealing channel and the brim are adapted to cooperate to form an assembled container having a substantially liquid proof seal, and wherein both the cup and lid arrays consist essentially of thermoformed polymeric material and are fabricated from different sheets of polymeric material. 2. The container ensemble of claim 1, wherein each lid and each cup comprises a plurality of rounded corners disposed about a periphery thereof. 3. The container ensemble of claim 2, further comprising a sealing bead centrally disposed on a wall of the sealing channel or a wall of the brim between each set of adjoining corners, wherein the sealing bead projects away from the wall of the channel or the wall of the brim and has a maximum distance of projection at a center thereof that tapers toward the wall as the sealing bead approaches each corner. 4. The container ensemble of claim 3, wherein a surface of an outer wall of the sealing channel is flat, wherein the sealing bead is disposed on an outer wall of the brim, and wherein the sealing bead is adapted to sealingly engage the flat surface of the sealing channel. 5. The container ensemble of claim 3, wherein a surface of an outer wall of the brim is flat, wherein the sealing bead is disposed on an outer wall of the sealing channel, and wherein the sealing bead is adapted to sealingly engage the flat surface of the brim. 6. The container ensemble of claim 3, wherein each sealing bead has an arched profile. 7. The container of claim 3, wherein each sealing bead has a semi-circular profile. 8. The container ensemble of claim 1, wherein the brim and the sealing channel have a U-shaped profile and are adapted to matingly engage one another. 9. A container assembly, comprising: a first array comprising a plurality of substantially planar lids, each lid having a sealing channel and a skirt extending outwardly therefrom and completely thereabout, wherein at least four corners are disposed about the lid, and wherein the lids are integrally formed and tearably joined to each other; and a second array comprising a plurality of cups, each cup having a brim and a skirt extending outwardly therefrom, wherein at least four corners are disposed about the cup, and wherein the cups are integrally formed and tearably joined to each other, wherein the sealing channel and the brim are adapted to cooperate to form an assembled container having a substantially liquid proof seal, and wherein the brim comprises an inner wall and an outer wall; and a sealing bead centrally disposed on the outer wall of the brim between each set of adjoining corners, wherein the sealing bead projects away from the outer wall and has a maximum distance of projection at a center thereof that tapers toward the wall as the sealing bead approaches each corner. 10. The container assembly of claim 9, further comprising a sealing bead centrally disposed on the inner wall of the brim between each set of adjoining corners, wherein the sealing bead projects away from the inner wall into a volume of the cup and has a maximum distance of projection at a center thereof that tapers toward the inner wall as the sealing bead approaches each corner. 11. The container assembly of claim 9, wherein the sealing channel comprises an inner wall and an outer wall, wherein a sealing bead is centrally disposed on the outer wall of the sealing channel between each set of adjoining corners, wherein the sealing bead projects away from the outer wall and has a maximum distance of projection at a center thereof that tapers toward the outer wall of the sealing channel as the sealing bead approaches each corner. 12. The container assembly of claim 9, wherein the sealing channel comprises an inner wall and an outer wall, wherein a sealing bead is centrally disposed on the inner wall of the sealing channel between each set of adjoining corners, wherein the sealing bead projects away from the inner wall and has a maximum distance of projection at a center thereof that tapers toward the inner wall of the sealing channel as the sealing bead approaches each corner. 13. The container assembly of claim 9, wherein both the cup and lid arrays consist essentially of thermoformed polymeric material and are fabricated from different sheets of polymeric material. 14. A container assembly, comprising an array of cups and an array of lids; wherein each lid comprises: at least three rounded lid corners; a lateral lid wall extending between two adjacent rounded lid corners; and a sealing channel and a skirt extending outwardly therefrom and completely thereabout, wherein the lids are integrally formed and tearably joined to each other; wherein each cup comprises: at least three rounded brim corners; a lateral brim wall extending between adjacent rounded brim corners; and wherein the cups are integrally formed and tearably joined to each other, wherein the lateral lid walls are configured to engage the brim walls of a corresponding cup; and a sealing bead centrally disposed on each lateral lid wall or each lateral brim wall, wherein each sealing bead projects away from the lateral wall having a maximum distance at a central portion thereof and tapers downwardly to the lateral wall as the sealing bead approaches each adjacent corner. 15. The container assembly of claim 14, wherein the sealing bead continuously tapers downwardly from the maximum distance to the lateral wall as the sealing bead approaches each adjacent corner. 16. The container assembly of claim 14, wherein each lateral lid wall and each lateral brim wall have a sealing bead disposed thereon. 17. The container assembly of claim 14, wherein each lateral lid wall comprises a channel having an inner wall and an outer wall, and wherein the inner wall, the outer wall or both have a sealing bead disposed thereon. 18. The container assembly of claim 14, wherein each lateral brim wall comprises an inner wall and an outer wall, and wherein the inner wall, the outer wall, or both have a sealing bead disposed thereon. 19.
