Stackable portable cooler system

Abstract

A portable cooler stacking system is provided, where portable coolers of different shapes and sizes can be optimally and stably stacked. The cooler system can include a first cooler having a first size and a second cooler having a second size, where the first and second sizes are different. A pair of second coolers can be stacked on the first cooler, where the second coolers are positioned widthwise along the length of the lid of the first cooler. In this manner, an inner length of the top surface of the lid of the first cooler is slightly greater then the width of a lower portion the second coolers and the inner width of the top surface of the lid of the first cooler is greater then two times the width of the lower portion of the second coolers. As such, two second cooler can be positioned widthwise along the length of the lid of the first cooler. The adjacent position of the second coolers and the interlocking surfaces substantially limit the horizontal movement of the pair of second coolers on the lid of the first cooler.

Description

FIELD OF THE INVENTIONThe present disclosure relates to a portable insulated container, namely, a portable cooler, and more particularly to a system for stacking a plurality of portable coolers.BACKGROUND OF THE INVENTIONA portable cooler typically has an insulated body presenting an open interior space in which ice and one or more articles to be cooled are stored. A lid, which can be hinged, and is also formed of insulative material, is provided on the cooler for closing the interior space in order to maintain the temperature of the articles in the cooler. Handles are usually secured to or formed in the cooler for facilitating transportation thereof, and a drain may be fitted in the body for draining water and other liquids from the cooler without opening the cover. The lid is provided with a flat top surface.During transport and storage portable coolers can be stacked on top of one another. However, as these coolers are available is a variety of shapes and sizes, it can be difficu...

AI Technical Summary

Benefits of technology

The present disclosure provides a portable cooler stacking system, where portable coolers of different shapes and sizes can be optimally and stably stacked. The cooler system can include a first cooler having a first size and a second cooler having a second size, where the first and second sizes are different.

The edge of the lower portion of the insulated body of the second cooler can have a curved shape, which is substantially opposite to the curved surface extending between the raised outer edge and the top surface of the lid of the first cooler. When the insulated body of a first second cooler is stacked, positioned, on top of the insulated lid of the first cooler, these surfaces mate, interlock, to substantially limit the widthwise horizontal movement of the second cooler on the lid of the first cooler. When a second insulated body of a second second cooler is stacked, positioned, on top of the insulated lid of the first cooler, adjacent to the first second cooler, the adjacent position of the second coolers and the interlocking surfaces substantially limit the lengthwise horizontal movement of the pair of second cooler on the lid of the first cooler.

Problems solved by technology

However, as these coolers are available is a variety of shapes and sizes, it can be difficult to optimally stack different shape and size coolers in a stable arrangement.

The height and physical structure of conventional coolers also makes it difficult to stack such coolers in a stable arrangement.
