STORAGE BIN ASSEMBLY FOR A REFRIGERATOR
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention pertains to the art of refrigerators and, more
s particularly, to a storage bin assembly for retaining articles on a door of
a
refrigerator.
2. Discussion of the Prior Art
It is well known in the art of refrigerated appliances to form doors
having inner liners that are provided with structure to support storage
to units for retaining various food containers. Typically, the storage units
are in the form of fixed or removable bins that are supported by the door.
The removable bins can be arranged at various positions on the inner liner
to provide adequate spacing for food items and containers having varying
heights.
CA 02484872 2004-10-15
In many cases, the bins are of a unitary construction and typically
injection molded from plastic. In other cases, the bins are formed from
multiple pieces that enable designers to construct creative shapes and/or
tailor the bins to meet particular consumer tastes. Multiple-piece bins
generally take the form of a base portion to which is attached a unique
facade. The facade can either be opaque or transparent and shaped or
formed with various designs that enable the bin to blend or otherwise
compliment aesthetic features present in the refrigerator.
The prior art contains a number of examples of mufti-piece bins, as
io well as methods of attaching a facade to a base portion. Ideally, the base
portion is designed so as to cooperate with a wide range of appliance
platforms and to accept a wide variety of facades. In this manner, a
single base portion can be employed to create a number of different
storage bin configurations for use in various appliance models. The prior
is art contains examples of securing facades to the base portion through use
of adhesives, sonic welding or through a simple snap-in arrangement.
While each method has a particular advantage, the snap-in arrangement
results in lower manufacturing costs.
Despite the existence of mufti-piece storage bins in the prior art,
zo there still exists a need for simple, cost effective and robust mounting
arrangements for securing facades to bases of mufti-piece storage bins.
