This invention relates to a refrigerator and
more especially to a refrigerator of the bottle

type for refrigerating bottled beverages wherein
?n coils or other suitable type of coils are dis

terior of the refrigerator as well as along the
top of the refrigerator and wiped by the air cir
culating in the refrigerator, withsuitable doors
provided on the upper portion of the rear wall
10 of the refrigerator.
It is therefore an object of this invention to
provide an elongated refrigerator having a front
wall, and a rear wall of lesser height than the
front wall, with a top disposed thereon and pro

disposed not only on each side of the refrigerator
but also in the top thereof.
