ABSTRACT:
A package for a folded inner tube for a pneumatic tire, e.g., a bicycle inner tube. The package is formed of a flexible material, and is in the form of a gussetted bag, defining a hollow interior in which the inner tube is located. The package includes plural panels or walls and a mouth which is arranged to be readily peeled open to provide access to the inner tube. When the vacuum is applied, this causes the material forming the package to closely conform to the exterior shape of the inner tube located within the package's hollow interior. This close conformance hardens the package, e.g., makes it resistant to injury. The close conformance of the walls of the package with the inner tube also causes the exterior surface of the package to assume an uneven, e.g., dimpled, state. If a wall of the package has been breached, as could occur by virtue of an impact by a sharp object, so that there is a loss of vacuum within the package, the material forming the walls of the package will tend to naturally assume their normal flat appearance. Thus, the user will be alerted to the possibility of injury to the inner tube by virtue of a smooth appearance of the package's walls.
