Problems solved by technology

Coolers are carried by hand and are difficult to carry over long distances, in crowds, or where having hands free would be an advantage.
The soft cloth-like material generally does not insulate and do not provide adequate protection against damage due to being bumped or crushed from the outside.

Embodiment Construction

[0011] A description of a rigid backpack for use in carrying and storing items that require cooling or are easily damaged, such as food, canned or bottle drinks and so forth, is provided. The rigid backpack includes at least one compartment and can include upper and lower compartments. The compartments are formed from rigid materials such as metal or formable plastics.

[0012] Separable lower and upper compartments of a rigid backpack are shown in FIG. 1. Generally, the compartments are polyhedrals with flat or curved surfaces. Alternatively, the compartments can have other shapes that are more spherical, have special design surfaces that reflect logos, and so forth. The compartments are rigid, and can be formed from either a single layer of material or from multiple layers. Non-rigid layers can be used in combination with other layers of material so long as the overall combination of layers is rigid. For example, to insulate a compartment an outer metal layer that is rigid can be co...

Abstract

A rigid backpack that includes at least one compartment and can include an upper compartment (103) that is attached to a lower compartment (101) is described. A top surface (105) of the lower compartment (101) is complementary to a bottom surface (107) of the upper compartment (103) such that the upper compartment (103) stacks on and attaches to the lower compartment (101). A waist strap (123) is attached to the lower compartment (101). Similarly, a right should strap (127) and a left shoulder strap (129) are attached to upper compartment (103).
