Description

Thermally insulated container with drawer Cross Reference to Related Applications The present application claims priority from PCT patent application No. PCT/CN2023/119079 filed on 9/15 of 2023, the entire contents of which are incorporated herein by reference. Technical Field The present disclosure relates generally to insulated containers with drawers. Background Portable insulated containers such as coolers allow items such as beverages and foods to remain cold outdoors, in a vehicle, or otherwise outside a refrigerator or freezer. Portable coolers typically have an insulated interior cavity in which a coolant (such as ice or a reusable cooling pack) is placed to assist in cooling the items in the cooler. When the coolant thaws or melts, the coolant itself and/or condensate from the coolant may cause the items in the cooler to become wet. Wetting of the article may result in one or more undesirable effects such as undesirably wetting the article, making the article difficult and/or messy to handle (unless cleaned with towels or other materials), damaging the paper packaging of the article, and the like. Disclosure of Invention Generally, systems, devices, and methods for insulated containers with drawers are provided. In one aspect, an insulated container is provided that in one embodiment includes an upper housing and a lower housing. The upper and lower housings are separated by a horizontal partition wall formed of a material having a thermal conductivity of about 0.3W/m K or less. The horizontal partition wall is integrally formed with the upper housing. The horizontal dividing wall has a plurality of ribs along a bottom surface of the horizontal dividing wall, a thickness between about 7mm and about 11mm, and a maximum deformation factor of 5 or less when the horizontal dividing wall is subjected to a force between about 1kPa and about 2 kPa. The deformation factor is determined by dividing the maximum deformation of the horizontal dividing wall by the thickness. The insulated container may be varied in any number of ways. For example, the horizontal dividing wall may have a total surface area of between about 0.1 square meters and about 0.2 square meters, such as about 0.15 square meters. The horizontal dividing wall may be formed of polypropylene. In another example, the insulated container may include a vertical dividing wall positioned within the lower housing and configured to support a central portion of the horizontal dividing wall. In the first configuration, the vertical dividing wall may support between about 0.25 and about 0.75 of the width of the horizontal dividing wall. In the first configuration, the deformation factor may be 1 or less. In the second configuration, the vertical partition wall may support the entire width of the horizontal partition wall. In the second configuration, the deformation factor may be 1 or less. In another aspect, an insulated container is provided that in one embodiment includes an upper housing and a lower housing. The upper and lower housings are separated by a horizontal partition wall formed of a material having a thermal conductivity of about 0.3W/m K or less. The horizontal partition wall is integrally formed with the upper housing. The horizontal dividing wall has a plurality of hexagonal ribs arranged in a honeycomb pattern along a bottom surface of the dividing wall, a total surface area between about 0.1 square meters and about 0.2 square meters, and a maximum plastic strain value of 190% or less when the horizontal dividing wall is subjected to dynamic forces between about 1kPa and about 2 kPa. The insulated container may be varied in any number of ways. For example, the maximum plastic strain may be less than the elongation at break value. The elongation at break value may be about 200% strain. The horizontal dividing wall may be formed of polypropylene. In another example, the insulated container may include a vertical dividing wall positioned within the lower housing and configured to support a central portion of the horizontal dividing wall. In the first configuration, the vertical dividing wall may support a width of the horizontal dividing wall between about 0.25 and about 0.75. In the second configuration, the vertical partition wall may support the entire width of the horizontal partition wall. In yet another example, the upper and lower housings may be separated from each other. The upper housing may have a plurality of first walls defining a main chamber configured to receive a coolant therein. The lower housing may have a plurality of second walls, the walls defining a drawer chamber configured to receive a drawer therein. In another aspect, an insulated container is provided that in one embodiment includes a housing having a substantially rigid polypropylene horizontal divider that includes a top imperforate surface that may be substantially smooth and a bottom surface having a plurality of ribs defining apertures therebetween, the r
