An example portable container is described. The example portable container includes a body, a handle, a pair of wheels, a wheel lock, and an authenticator. The body includes walls that form an inner chamber configured and dimensioned to receive one or more items. The handle is mounted to the body, and the pair of wheels is mounted to the body. The wheel lock is configured to selectively engage and disengage at least one wheel of the pair of wheels. Engagement of the at least one wheel with the wheel lock restricts rotation of the wheel. The authenticator is configured to authenticate a user for transporting the portable container. If the authenticator fails to authenticate the user, the wheel lock is actuated to engage the at least one wheel of the pair of wheels to restrict rotation of the wheel.

A wheeled kitchen apparatus with a collapsible work surface includes a wheeled cabinet with a cabinet top and four cabinet sides. The cabinet top has a surface with an opening accommodating a basin, and also has a heating unit. The cabinet has four extensions located at the four cabinet sides. The four extensions are configurable between at least two positions including a first position that laterally extends the surface of the top of the cabinet and a second position in which the extensions fold down along the sides of the cabinet. The unit can include running water, including hot and cold water, and can also include an oven. The collapsible work surface permits the apparatus to fit through classroom doors and therefore usable in every school environment. The shape of the extensions, when configured in the upward position, safely moves school-age children away from the potentially dangerous heating unit and other equipment that may pose harm if within reach of the children.

A mechanism for raising and lowering a cooking surface within a recessed combustion chamber is provided.

A modular preparation station system and method are provided. The modular preparation station system includes a base element with a perimeter track and a plurality of modular sidewall units which are engageable with the perimetral track to create an interior cavity with a variety of compartments such as to be adaptable to a wide range of commercial kitchen environments. The tracking is configured in a way to enable quick and accurate assembly of the modular preparation station internal cavity as well as to provide sufficient rigidity support and insulation to meet the needs of the commercial application. The preparation station system further includes a top element or working surface element with an adjustable cooling compartment. The top element secures to the interior cavity by way of one or more track allowing for efficient assembly and modification of the modular preparations station system.
