Description

TECHNICAL FIELD

The present application and the resultant patent relate generally to a refrigerated storage case and more particularly relate to a refrigerated storage case with a number of consumer accessible compartments sized for storing grocery orders and the like.

BACKGROUND OF THE INVENTION

Retail stores such as supermarkets and the like generally have a number of display cases such as refrigerated display cases with food and/or beverages displayed therein. A consumer may enter the store, select the desired items from the display cases or elsewhere, and proceed to checkout. An increasing trend in supermarket sales, however, is the use of online shopping for groceries and other items. Instead of entering the store in person to select his or her items, the consumer may select the desired items online and then supermarket personnel may retrieve the items and package them for later pickup or delivery. Other types of remote ordering devices and methods also may be in use.
While waiting on pickup or delivery, supermarket personnel generally either use large coolers to store the prepackaged items or they simply may leave the items on a countertop or other store location at an ambient temperature. The use of the large coolers is generally not energy efficient and may not be convenient for the consumer to find his or her package. Further, leaving the items at ambient temperatures may create freshness issues and may allow any frozen items to thaw if the pick up or the delivery is delayed.
There is thus a desire for an improved refrigerated storage case for prepackaged groceries orders and the like. Preferably such an improved refrigerated storage case may maintain the items therein in a refrigerated or frozen state while also being energy efficient, easy for store personnel to load items therein, and easy for consumers to remove items therefrom.

SUMMARY OF THE INVENTION

The present application and the resultant patent thus provide a refrigerated storage case for storing pre-selected items. The refrigerated storage case may include a number of compartments, a user interface configured to receive an access code and to unlock a predetermined compartment with the pre-selected items therein, and an evaporator coil configured to maintain the compartments at a chilled and/or a frozen temperature.
The present application and the resultant patent further provide a method for providing remote shopping or selection of one or more items. The method may include the steps of receiving an order for the one or more items, providing an access code for access to a compartment in a refrigerated storage case, placing the one or more items in the compartment of the refrigerated storage case, locking the compartment in the refrigerated storage case, receiving the access code, and unlocking the compartment in the refrigerated storage case to provide access to the one or more items.
The present application and the resultant patent further provide a refrigerated storage case for storing one or more pre-selected items. The refrigerated storage case may include a number of compartments with a first door and a second door, a user interface configured to receive an access code and to unlock a predetermined compartment with the pre-selected items therein, and a refrigeration system configured to maintain the compartments at a chilled and/or a frozen temperature.
These and other features and improvements of the present application and the resultant patent will become apparent to one of ordinary skill in the art upon review of the following detailed description when taken in conjunction with the several drawings and the appended claims.
