Protective structure of disc packaging

Abstract

A “protective structure of disc packaging” of the invention is composed of an upper lid, a lower lid and a casing that are formed on the top and the bottom sides and the perimeters of a pile of discs, and a heat-shrinkable film covers the protective body and said discs together to retaining the disc quality during the disc packaging and delivery processes. The characteristic of the invention lies in: the upper lid and the lower lid are respectively composed of at least two interlaced disc-shaped plates, which possess wavy buffer portions that are made of corrugated paper or plastic corrugated sheet. When the upper and the lower disc-shaped plates are disposed, the undulating buffer portions of the disc-shaped plates are vertically stacked up, in addition, the sizes of the disc-shaped plates are larger than the sizes of the discs and the casing being shaped as a roll.

Description

BACKGROUND OF INVENTION [0001] I. Field of the Invention [0002] This invention relating to the “protective structure of disc packaging” presents a simple form of disc protecting structure where placing the upper and lower layers of protection on the top and bottom of the discs with the added wrapping of the heat-shrinkable film and casing will prevent the deformation to the discs due to direct contact with the heat-shrinkable film. [0003] II. Description of the Prior Art [0004] There are an increasing number of consumer electronic products on the market that requires disc storage (such as CD, CD-R, CD-RW, DVD, DVD-R, DVD+R and DVD-RW, etc.); generally, a great quantity of blank discs are used either, by a computer disc burner or a VCD / DVD+R / RW recorder and the packaging of those blank discs are encased by some proper protective structures during the packaging and delivery processes. Nevertheless, sensing that the mounting hub manufactured for holding the disc media is 0.3 mm thicker...

Benefits of technology

[0008] The primary objective of the present invention is to provide a simplified protective structure with complete protection effect for retaining the disc quality during the disc packaging and transporting processes. In addition, this also meets the requirement of environmental protection and effectively reducing the disc packaging costs.

[0009] To achieve the above objective, the “protective structure of disc packaging” of the present invention primarily comprises of an upper lid, a lower lid and a casing, that are disposed on the top and bottom sides of the perimeters round the pile of discs. The upper lid and the lower lid are respectively composed of at least two interlaced disc-shaped plates, which possess wavy buffer portions that are made of corrugated paper or plastic corrugated sheet. When the upper and the lower disc-shaped plates are disposed, the undulating buffer portions of the disc-shaped plates are vertically stacked up, in addition, the sizes of the disc-shaped plates are larger than the sizes of the discs causing the casing to be shaped in a roll.

[0010] Upon the disc packaging, first of all, the invention enables the discs to be piled up, where the lower lid of the invention is placed on the bottom side of the pile of discs, and the casing sleeves over the perimeters of the discs as well as the upper lid being placed on the upper side of the

Problems solved by technology

Extra box packing process is not required, so as to reduce conventional use of packing boxes and partition plates where the discs containe
