An insert for protecting articles to be stored in a protective case. The insert is generally hollow and formed of a flexible thermoplastic material. The insert may be formed by a blow-molding process. The insert is shaped to fit within a protective case, which is also often formed by a blow-molded process. The material used to form the insert is less dense than that of the material used to form the protective case, and therefore the insert material is less stiff, softer, and more flexible.

1. A case for housing at least one object, comprising: a base portion comprising a first cavity;a lid portion connected by a hinge to the base portion and comprising a second cavity;a hollow insert comprising external walls, wherein the hollow insert is shaped to be receivable in one of the first cavity or the second cavity and at least one external wall has at least one recess shaped to receive the at least one object; andwherein the external walls of the hollow insert have a lower stiffness than the base portion and the lid portion. 2. The case of claim 1, wherein the base portion and the lid portion are formed by blow-molding. 3. The case of claim 1, wherein the hollow insert is formed by blow-molding. 4. The case of claim 1, wherein the hollow insert is a first hollow insert and the case further comprises a second hollow insert that is receivable in the other of the first cavity or the second cavity. 5. The case of claim 4, wherein the second hollow insert is shaped to press against the object when the object is received in the recess of the first hollow insert. 6. The case of claim 1, wherein the base portion, the lid portion, and the hollow insert comprise thermoplastic materials. 7. The case of claim 1, wherein the recess is shaped to correspond to the outline of the at least one object so that the recess secures the at least one object by friction. 8. The case of claim 1, wherein the interior of the hollow insert formed by the external walls is sealed to the environment external to the hollow insert. 9. The case of claim 8, wherein the pressure inside the hollow insert is greater than 1 atmosphere. 10. The case of claim 1, wherein the interior of the hollow insert formed by the external walls is in fluid communication with the environment external to the hollow insert. 11. An insert receivable within a protective case for holding at least one object, the protective case comprising an external shell and said insert comprising: a bottom wall;a plurality of side walls; anda top wall, having at least one recess shaped to correspond to the outline of the at least one object for receiving the at least one object;wherein the bottom wall, side walls, and top wall form a hollow interior of the insert; andwherein the bottom wall, side walls, and top wall are less stiff than the external shell of the case within which the insert is disposed so as to provide cushioning to the object. 12. The insert of claim 11, wherein the interior of the insert is sealed to the environment exterior to the insert. 13. The insert of claim 12, wherein the pressure in the interior of the insert is greater than 1 atmosphere. 14. The insert of claim 11, further comprising an opening such that the interior of the insert is in fluid communication with the environment exterior to the insert. 15. The insert of claim 11, wherein the insert comprises a thermoplastic material. 16. A method for producing a case comprising an external shell and an insert for storing at least one object, comprising the steps of: molding a base portion and a lid portion of the external shell;forming a cavity in one of the base portion or the lid portion of the external shell;molding a hollow insert shaped to be receivable in the cavity, comprising a bottom wall, a plurality of side walls, and a top wall which together form a hollow interior of the insert, such that the bottom wall, side walls, and top wall have a lower stiffness than the external shell;placing the hollow insert in the cavity. 17. The method of claim 16, wherein the step of molding a base portion and a lid portion of an external shell comprises blow-molding the base portion and the lid portion of the external shell using a single mold. 18. The method of claim 16, wherein the step of forming a cavity in one of the base portion or the lid portion of the external shell comprises removing a section of a surface of one of the base portion or the lid portion. 19. The method of claim 16, wherein the step of molding a hollow insert comprises blow-molding. 20. The method of claim 16, wherein the step of molding a base portion and a lid portion of an external shell comprises: blow-molding the base portion using a first mold;blow-molding the lid portion using a second mold; andjoining the base portion and the lid portion by a hinge.
