## Background
RELATED APPLICATIONS
The present invention was first described in and claims the benefit of U.S. Provisional Application No. 61/928,633, filed Jan. 17, 2014, the entire disclosures of which are incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates generally to a wheeled transportation device particularly suited for transporting a slow cooker type of food container.
BACKGROUND OF THE INVENTION
Slow cookers or CROCK-POTS® as they are commonly called, are frequently used to make a wide variety of dishes such as stews, chilis, soups, pot roasts, and the like. While these foods are perfect for meals at home, they also find a high percentage of use at picnics, tail gate parties, office functions, and pot luck dinners. These occasions mean that the slow cooker must be transported to a remote location where the cooking process continues, or for keeping the food warm for long periods of time. However, these slow cookers can weigh up to twenty-five pounds (25 lbs.) when filled with food. While they can be easily lifted and carried for a few feet, transport through large parking lots, or carrying into a large building becomes very difficult for even those in the best of physical shape. Those who may be elderly, of a small physical stature, or those suffering from an injury or disability find moving heavy slow cookers impossible. Accordingly, there exists a need for a means by which slow cookers can be easily moved and transported, without the disadvantages as described above.
SUMMARY OF THE INVENTION
The disadvantages of the prior art are overcome by the present invention in providing a wheeled transport for a cooking container having a lower enclosure adapted to accept and retain the container and an upper enclosure hingedly affixed to the lower enclosure and adapted to close upon and seal the lower enclosure. The invention includes a handle assembly selectively movable between a deployed position and stowed position and a pair of wheels operatively attached to the bottom surface of the lower enclosure. The use of the present invention provides a means of moving and transporting heavy, filled, slow cookers, in a manner that is not only quick, easy, and effective, but unique, safe, and secure as well.

The aforementioned lower enclosure assembly 20 provides an open top box-like rigid structure having a first side panel 22a, a second side panel 22b, a front panel 23, a rear panel 24, and a bottom panel 25. The panel portions 22a, 22b, 23, 24, 25 provide a single piece construction of flat plastic or metal panels arranged at right angles, and being covered along all interior surfaces by an insulation layer 28 such as polystyrene or equivalent durable lightweight insulating material envisioned to be adhesively bonded to the panes 22a, 22b, 23, 24, 25. The lower enclosure assembly 20 further includes a pair of hinges 36 along a rear upper edge, and a first zipper 80a which extends along side and front edges which provide respective hinged attachment and closure with specs to the upper enclosure assembly 40. The lower enclosure assembly 20 is envisioned to be introduced in several sizes having lower enclosure inner cavities 21 which facilitate correspondingly sized slow cookers 100, and as such should not be interpreted as a limiting factor of the apparatus 10.
The lower enclosure assembly 20 also includes a louver-type vent 35 and a pouch 30 both built into the rear panel 24. The vent 35 enables escape of expanding gases, steam, and the like, emitted from the slow cooker 100. The rectangular transparent pouch 30 provides a low profile envelope structure having a third zipper 80c along a top edge and is envisioned to be affixed along an outer surface portion of the rear panel 24 using methods such as radio frequency (RF) welding, heat sealing, adhesive bonding, and the like. The pouch 30 is to be suitable in size to contain and display a rectangular document 32 such as a recipe sheet, a menu, or an instruction sheet, as well as different advertisement displays providing various indicia 33.
The lower enclosure assembly 20 provides equipment to enable easy transportation of the apparatus 10 in the slow cooker 100 along a ground/floor surface 210 including a pair of casters 26, a pair of legs 27, and a pull-handle assembly 50. The casters 26 are affixed at front corner portions of the bottom panel 25, and the legs 27 at rear corner portions of the bottom panel 25. The casters 26 and legs 27 are envisioned to have similar vertical heights, thereby enabling the lower enclosure assembly 20 to assume a stable level position upon a ground/floor surface 210 when in an upright position.
The upper enclosure assembly 40 provides a rectangular semi-rigid textile enclosure material 42 affixed to a rigid upper enclosure base 43 that defines a inner cavity 41. The preferred embodiment of the upper enclosure assembly 40 has a similar width and length as the subjacent lower enclosure assembly 20 and is approximately six inches (6 in.) in height. The upper enclosure assembly 40 also provides an upper enclosure flap 44 that is a portion of the enclosure material 42 and operatively opens by a second zipper 80b. Stored beneath the upper enclosure flap 44 within the inner cavity 41 is a utensil tray 45. The zipper 80b allows the flap 44 to be opened across the top of the upper enclosure assembly 40 and along its front face, thereby allowing convenient horizontal extraction of the utensil tray 45 (see FIG. 4). The upper enclosure assembly 40 is hingedly attached to the lower enclosure assembly 20 by the hinges 36.
The handle assembly 50 provides a top horizontal pull-handle portion 56 disposed between two (2) telescoping members each having an upper and lower member that collapse within a handle case 62.
