Clamshell packaging with built-in CD case that secures the CD by a formed plastic button

Disclosed is a design for clamshell packaging with a built-in CD case that secures the CD by a formed/plastic button. Benefits include improved packaging that provides ESD and physical protection and enables automated loading. Environmental benefits result from the discontinuance of conventional ESD bags.

A thermoformed clamshell provides protective packing for an adapter card. The exterior of the clamshell has a place on its exterior when the CD that accompanies the card can be seated into a protected area (see Figure 1). When in place, the CD is held by a unique thermoformed button. One side of the CD is protected by the clamshell. The unprotected side of the CD rests just a fraction of an inch beneath the surface of the clamshell (see Figure 2). When the clamshell (with the CD attached) is fitted into the shipping carton, the CD is protected. The artwork on the surface of the CD is shielded from rubbing or scratching because the CD is not in contact with the side of the box.

The clamshell is manufactured by thermoforming a polymer that is coated with an ESD protective chemical. The ESD-protective chemical does not adversely affect any of the properties of the plastic. The clamshell with the ESD-protective coating passes all compliance regulations and is completely recyclable.

A thermoformed gripping button holds the CD in place. The button has a unique shape that enables the CD to be cleanly seated into the clamshell and firmly fastens the CD until the package is opened and the button is affirmatively pushed to release the CD. The novel shape of the channel that is thermoformed into the button (see Figures 3-5) provides this functionality. The button continuously holds the CD until the button is pushed down. Then, the CD easily releases from the thermoformed clamshell.

Conventionally, many clamshells have been designed to protect electronic components from ESD during shipping. However, none has a feature like the protected area for a CD incorporated into an adapter clamshell, and none has a gripping button. These two features make the clamshell a dual-purpose package that is unique.

An ESD bag is another conventional way to provide ESD protection. When bagged adapter cards are packed into a larger box, cushioning protection is also required. Dividers are inserted to separate the adapter cards to keep them from hitting each other. Foam pads are placed on the top and bottom of the shipping box so that the boards do not hit the bottom of the box and get damaged. The disclosed clamshell eliminates the requirement for the ESD bag and the cushioning protection. Approximately 20 clamshells may be placed in a row in a shipping carton and enclosed. Because of the effectiveness of the packaging, the procedure of loading the board into the clamshell, closing the clamshell, and placing the clamshells into a box for shipping may be automated.
