Abstract
Various systems, devices, and methods for insulated containers with a drawer are provided. In general, an insulated container, such as a portable cooler, includes a drawer. The insulated container includes a main chamber and includes a drawer chamber that is separate from the main chamber and is configured to movably receive the drawer therein. The main chamber is configured to hold a cooling agent that is configured to cool any items in the main chamber and also any items in the drawer. The insulated container can be manufactured using injection molding.
Claims21
A method of manufacturing an insulated container, comprising:
- forming an upper housing of an insulated container with injection molding of polypropylene such that the upper housing is a singular member that has:
- a main chamber therein, the main chamber being configured to receive a cooling agent that is configured to cool one or more first items removably contained in the main chamber,
- an open upper end,
- sidewalls that each has a thickness in a range of about 2.5 to about 3.5 mm, and
- a bottom wall that has a thickness in a range of about 2.5 to about 3.5 mm and that includes a plurality of ribs;
- forming a lower housing of the insulated container with injection molding of polypropylene such that the lower housing is a singular member that has:
- a drawer chamber, the drawer chamber being configured to slidably receive a drawer therein that is configured to removably contain one or more second items therein,
- sidewalls that each has a thickness in a range of about 2.5 to about 3.5 mm, and
- an open upper end;
- and
- fixedly securing the upper and lower housings together such that the bottom wall of the upper housing defines a top wall of the drawer chamber and separates the main chamber from the drawer chamber.
A method of manufacturing an insulated container, comprising:
- forming an upper housing of an insulated container with injection molding of polypropylene such that the upper housing is a singular member that has:
- a main chamber therein, the main chamber being configured to receive a cooling agent that is configured to cool one or more first items removably contained in the main chamber,
- an open upper end, and
- a bottom wall that includes a plurality of ribs;
- forming a lower housing of the insulated container with injection molding of polypropylene such that the lower housing is a singular member that has:
- a drawer chamber therein that is configured to slidably receive a drawer therein that is configured to removably contain one or more second items therein, and
- an open upper end;
- fixedly securing the upper and lower housings together such that the bottom wall of the upper housing defines a top wall of the drawer chamber and separates the main chamber from the drawer chamber;
- coupling a lid to the upper housing such that the lid defines a top wall of the main chamber;
- forming the drawer with injection molding of polypropylene;
- and
- disposing the drawer in the drawer chamber such that, with the drawer fully disposed in the drawer chamber, the drawer chamber is sealed closed;
- wherein the lid is configured to move between a closed configuration, in which the main chamber is sealed closed, and an open configuration, in which the main chamber is not sealed closed and the one or more first items removably contained in the main chamber are accessible to a user;
- with the upper and lower housing fixedly secured together, the drawer is configured to be slid at least partially out of the drawer chamber without breaking the seal of the main chamber;
- and
- with the drawer chamber sealed closed and with the upper and lower housings fixedly secured together, the lid is configured to move from the closed configuration to the open configuration without breaking the seal of the drawer chamber.
