Abstract: A retainer assembly for preventing tall food containers placed on a shelf of a refrigerator door liner from falling off the shelf when the refrigerator door is abruptly opened or closed includes a retainer member in the form of an elongated rod or bar that includes an intermediate portion and bent end sections and a retainer element. Each of the bent end sections includes an out-turned terminal end that is pivotally connected to the dike portion of the inner liner. The retainer element preferably comprises a block that defines various spaced grooves or recesses. The retainer element is attached to a sidewall of the dike portion with the various grooves being spaced vertically.
