The combination of a portable musical instrument and a thermally insulating case defining a storage space within which at least a majority of a volume of the portable musical instrument resides with the musical instrument in a stored state. The thermally insulating case has a wall with an inside and an outside and that bounds at least a part of the storage space. The wall has at least: a) an inside layer; b) an outside layer; and c) an insulating region between the inside and outside layers. The wall has a flexible shape allowing the wall to be readily reconfigured.

An insulating device can include a body assembly and a lid assembly where an insulating layer is connected to both the body assembly and the lid assembly. An aperture with a closure is formed between the body assembly and lid assembly to form a storage compartment. An insulating tab may be formed from a portion of the insulating layer and an inner liner of the body assembly to help insulate the closure region. In addition, a first magnetic element may be secured within the insulating tab that may engage a second magnetic element secured within the lid assembly.

An insulating device can include an aperture having a waterproof closure which allows access to the chamber within the insulating device. The closure can help prevent any fluid leakage into and out of the insulating device if the insulating device is overturned or in any configuration other than upright. The closure may also prevent any fluid from permeating into the chamber if the insulating device is exposed to precipitation, other fluid, or submersed under water. The insulating device may include a back panel support structure and shoulder straps allowing the device to be worn as a backpack. This construction results in an insulating chamber that is substantially impervious to water and other liquids when the closure is sealed.

An insulated bag reduces heat exchange between temperature-sensitive items and ambient surroundings. The insulated bag has a bag body which can be covered by a bag lid. The bag lid is provided with a first portion of a securing element. The insulated bag is suitable for insertion into an item space of a mobile delivery robot. The mobile robot has a robot lid provided with a complementary second portion of the securing element. After the insulated bag is inserted into the item space, the two portions of the securing element are connected. Thereafter, when the robot lid is opened, the bag lid is also opened, permitting access to its contents.

A thermal bag includes a thermal bag main body and an upper cover. A side shaping board is interlaid between the fabrics around the thermal bag main body. The upper cover includes a pair of half covers. An opening assembly is connected between the two half covers. Atop shaping board is interlaid between the fabrics of each of the half covers. A hinge assembly is connected between the side shaping board and the top shaping board located at the same side of the opening assembly. The hinge assembly drives the half covers to open/close the opening of the thermal bag quickly.

Molded foam articles are provided. The molded foam articles have at least one surface having at least a portion that has been skin-formed for improving the thermal and mechanical properties of the molded foam articles without the need for material, density, or foam particle size changes.
