Abstract
Abstract A meat keeper compartment includes an adjustable air duct assembly which supplies cold air flow from the evaporator compartment of a top freezer type refrigerator into a meat keeper receptacle slidably mounted on a shelf which may be positioned at different levels or on different sides of the fresh food compartment of the refrigerator. The air duct assembly consists of an air deflector which receives cold air from the freezer through a slot in the partition between the freezer and fresh food compartment, a cold air outlet to deliver cold air into the meat keeper receptacle, an upper air duct having the back wall of the refrigerator form the back wall of the duct, a lower air duct which telescopes with the upper air duct for adjustment of the cold air outlet, and an adjustable air damper for regulation of the amount of cold air flow.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
86 words
A meat keeper compartment in a refrigerator having a freezer compartment and a separate fresh food compartment comprising: a meat keeper receptacle; means for mounting the meat keeper receptacle at different laterally spaced positions within the fresh food compartment; a duct in said fresh food compartment channelling cold air from the freezer compartment into the meat keeper receptacle; and means to mount said air duct at different laterally spaced positions in said fresh food compartment corresponding to said different lateral positions of the meat keeper receptacle.
Claim 2
Dependent Claim
86 words
A meat keeper compartment in a refrigerator having a freezer compartment and a separate fresh food compartment comprising: a meat keeper receptacle; means for mounting the meat keeper receptacle at different laterally spaced positions within the fresh food compartment; a duct in said fresh food compartment channelling cold air from the freezer compartment into the meat keeper receptacle; and means to mount said air duct at different laterally spaced positions in said fresh food compartment corresponding to said different lateral positions of the meat keeper receptacle.
Claim 3
Dependent Claim
31 words
A meat keeper compartment as set forth in claim 1, wherein the duct includes adjustable damper means to regulate the flow of air from the freezer compartment to the storage container.
Claim 4
Dependent Claim
41 words
A meat keeper compartment as set forth in claim 1, wherein the meat keeper receptacle occupies about one half the width of the fresh food compartment and said different laterally spaced positions are on either side of the fresh food compartment.
Claim 5
Dependent Claim
50 words
A meat keeper compartment as set forth in claim 3, wherein the means for mounting the meat keeper receptacle comprises a cantilevered shelf which can be positioned at different vertical levels and at different sides within the fresh food compartment and which forms the cover for the meat keeper receptacle.
Claim 6
Dependent Claim
86 words
A meat keeper compartment as set forth in claim 1, wherein the air flow assembly comprises an air deflector, an upper air duct and a lower air duct, in which the air deflector directs air from the freezer compartment into the upper air duct, the upper air duct directs air into the lower air duct, and the lower air duct directs air through an aperture in the meat keeper receptacle; and where the lower air duct cooperates with the upper air duct in a telescoping manner.
Claim 7
Dependent Claim
57 words
A meat keeper compartment as set forth in claim 4, wherein the air deflector has a central air channel which directs air from the freezer into the fresh food compartment and has side channels whereby air is directed through one side channel into the meat keeper receptacle and through another side channel into the fresh food compartment.
Claim 8
Dependent Claim
36 words
A meat keeper compartment as set forth in claim 4, wherein the back wall of the refrigerator forms at least a portion of the back walls of the upper air duct and the lower air duct.
Claim 9
Dependent Claim
24 words
A meat keeper compartment as set forth in claim 1, wherein the duct is secured within the fresh food compartment by a single fastener.
Claim 10
Dependent Claim
168 words
In a refrigerator having a top freezer compartment separated by a partition from the fresh food compartment, a meat keeper compartment comprising: a meat keeper receptacle of about half the width of the fresh food compartment; a vertically positionable shelf whereby the meat keeper receptacle is mounted from the shelf, the shelf forming the cover of the meat keeper compartment and the meat keeper compartment being mountable on either side of the fresh food compartment; an air deflector which is mounted to the partition which receives cold air from the freezer through an aperture in the partition, the air deflector having a central channel and two side channels; an upper air duct which cooperates with the air deflector and can be mounted from either side of the air deflector and receives air from one of the side channels; a lower air duct which telescopes into the upper air duct; and an adjustable damper means to regulate the flow of air from the freezer compartment to the storage container.
Claim 11
Dependent Claim
168 words
