<p>Groceries ordered over the Internet by a particular time in the early evening may be delivered by the next morning to a location within a 5-6 hour delivery radius of a warehouse. The grocery order is filled at the warehouse, where the groceries are placed in a tote for delivery. If perishable groceries are to be delivered, a frozen insert is placed in the tote to maintain the groceries at a desired temperature. The filled tote is placed on a rack, which is removable with the tote on it. The racks have shelves that are pitched such that when a first tote is removed a second tote behind the first tote falls into the space previously occupied by the first tote. In the early evening, after the cutoff time for placing orders, the rack and totes on the rack are transferred to a first vehicle, typically a large trailer, that transports the rack and totes to a transfer point where the rack and the accompanying bill of lading are transferred to a second smaller vehicle, such as a van. The van delivers the totes to customers along a pre-established route. Upon reaching a delivery destination (usually a customer's home) by early the next morning, the van driver removes the tote for that customer from the van and secures it in a locked expandable bag, such as a mesh net or insulated bag, that may be locked in two places and that is itself secured to a grocery box. The grocery box, which is supplied to the customer by the business selling the groceries, is secured outside the delivery destination. The customer removes the tote from the bag, removes the groceries from the tote, and returns the used tote to the bag for later pickup by the van.</p> |
