Abstract

Abstract A container for sliced meat products or the like has a base including a marginal base flange, a raised pedestal, and a short peripheral sidewall connecting the pedestal to the marginal base flange. A cover is also provided including a marginal cover flange and a cavity, the cavity being formed by a raised top wall and a long peripheral sidewall connecting the marginal cover flange to the top wall. A plurality of concave channels are provided along the interior surface of the long peripheral sidewall. These channels extend from the top wall and terminate at a height above the marginal cover flange which is greater than or equal to the height of the short peripheral sidewall of the base. A plurality of depressions or grooves are also provided in the upper surface of the pedestal. Preferably, the grooves extend substantially perpendicularly to the adjacent portion of the short peripheral sidewall and are equidistantly spaced. In addition, the end of each groove adjacent the short peripheral sidewall is matingly positioned adjacent a corresponding lower end of a respective concave channel.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 295 words
In a container for sliced meat products or the like comprising: (a) a base which is horizontal in use including a marginal base flange, a raised pedestal having a flat support surface upon which the product rests, and a short peripheral sidewall extending vertically from said marginal base flange to said pedestal around the periphery of said pedestal; and (b) a cover which is horizontal in use including a marginal cover flange shaped complementary to said marginal base flange, a raised top wall under which the product is located, and a long peripheral sidewall extending vertically from said marginal base flange to said top wall around the periphery of said top wall and provided with concave channels along the interior surface extending vertically from said marginal cover flange to said top wall; said short peripheral sidewall of said base being snugly received inside said long peripheral sidewall of said cover with said marginal base flange sealingly attached to said marginal cover flange, a space being provided between said pedestal and said top wall in which the product is located; the improvement wherein: said concave channels terminate at a height above said marginal cover flange which is equal to or greater than the height of said short peripheral sidewall of said base such that after said short peripheral sidewall of said base is received inside said long peripheral sidewall of said cover, said concave channels terminate at or above said short peripheral sidewall; and a plurality of depressions are provided in the flat support surface of said pedestal in which free liquids from the product are collected wherein said depressions are grooves which extend longitudinally away from an adjacent portion of said short peripheral sidewall said flat support surface being spaced above said marginal cover flange.
Claim 2
Dependent Claim 295 words
In a container for sliced meat products or the like comprising: (a) a base which is horizontal in use including a marginal base flange, a raised pedestal having a flat support surface upon which the product rests, and a short peripheral sidewall extending vertically from said marginal base flange to said pedestal around the periphery of said pedestal; and (b) a cover which is horizontal in use including a marginal cover flange shaped complementary to said marginal base flange, a raised top wall under which the product is located, and a long peripheral sidewall extending vertically from said marginal base flange to said top wall around the periphery of said top wall and provided with concave channels along the interior surface extending vertically from said marginal cover flange to said top wall; said short peripheral sidewall of said base being snugly received inside said long peripheral sidewall of said cover with said marginal base flange sealingly attached to said marginal cover flange, a space being provided between said pedestal and said top wall in which the product is located; the improvement wherein: said concave channels terminate at a height above said marginal cover flange which is equal to or greater than the height of said short peripheral sidewall of said base such that after said short peripheral sidewall of said base is received inside said long peripheral sidewall of said cover, said concave channels terminate at or above said short peripheral sidewall; and a plurality of depressions are provided in the flat support surface of said pedestal in which free liquids from the product are collected wherein said depressions are grooves which extend longitudinally away from an adjacent portion of said short peripheral sidewall said flat support surface being spaced above said marginal cover flange.
Claim 3
Dependent Claim 15 words
A container as claimed in claim 1 wherein said grooves have a rounded cross section.
Claim 4
Dependent Claim 16 words
A container as claimed in claim 1 wherein said grooves extend to said short peripheral sidewall.
Claim 5
Dependent Claim 18 words
A container as claimed in claim 1 wherein said grooves terminate just prior to said short peripheral sidewall.
Claim 6
Dependent Claim 22 words
A container as claimed in claim 4 wherein said grooves extend substantially perpendicularly to said adjacent portion of said short peripheral sidewall.
Claim 7
Dependent Claim 21 words
A container as claimed in claim 1 wherein said grooves are equidistantly spaced from one another along said short peripheral sidewall.
Claim 8
Dependent Claim 36 words
A container as claimed in claim 1 wherein the end of each said groove adjacent said portion of said short peripheral sidewall is matingly positioned adjacent a corresponding lower end of a respective said concave channel.
Claim 9
Dependent Claim 21 words
A container as claimed in claim 7 wherein said grooves are equidistantly spaced from one another along said short peripheral sidewall.
Claim 10
Dependent Claim 27 words
A container as claimed in claim 1 and further including a central cavity in said pedestal, and wherein a plurality of said grooves open into said cavity.
Claim 11
Dependent Claim 19 words
A container as claimed in claim 1 wherein said pedestal is circularly shaped and said grooves are radially directed.
Claim 12
Dependent Claim 13 words
A container as claimed in claim 1 wherein said pedestal is rectangularly shaped.
Claim 13
Dependent Claim 49 words
A container as claimed in claim 11 wherein there is a corner groove adjacent each corner of said pedestal along each said side, wherein there are intermediate grooves between said corner grooves of each side, and wherein said corner grooves of said pedestal are shorter than said intermediate grooves.
Claim 14
Dependent Claim 33 words
A container as claimed in claim 1 wherein the distance between the height at which said concave channels terminate and the height of said short peripheral sidewall is from 0 to 0.6 cm.
