A clean room covering or enclosure for a portable computer, wherein the computer has a keyboard portion and a screen portion connected by a hinge foldable between closed and open positions. The enclosure comprises a flexible sleeve for receiving the keyboard portion of the portable computer, with the sleeve having an opening through which the keyboard portion is inserted and removed, a transparent portion for viewing and operating the keyboard and a gas permeable vent portion adapted to restrict flow of contaminant particles. A flexible flap extends from the sleeve portion and is adapted to wrap around and over the screen portion of the portable computer, and has a transparent portion for viewing the screen. The enclosure also includes a reclosable seal for securing the flexible flap around the screen portion. The reclosable seal preferably secures the flexible sleeve opening to restrict flow of contaminant particles.

Thus, having described the invention, what is claimed is: 1. A clean room enclosure for a portable computer, the computer having a keyboard portion and a screen portion connected by a hinge foldable between closed and open positions, the screen portion being disposed in a lid having a front side containing the screen, a back side opposite the screen, a top edge opposite the hinge and side edges between the top edge and the hinge, the enclosure comprising: a flexible sleeve for receiving the keyboard portion of the portable computer, the sleeve having an opening through which the keyboard portion is inserted and removed, a transparent panel portion for viewing and operating the keyboard and a gas permeable vent portion restricting flow of contaminant particles; a flexible flap extending from the flexible sleeve continuously from the hinge, along the lid back side, over the lid top edge and around the lid front side and wrapping around and over the screen portion of the portable computer, the flexible flap having a transparent portion for viewing the screen; and a reclosable seal adjacent a side edge of the lid between the front and back sides for securing the flexible flap around the screen portion whereby the enclosure restricts passage of contaminant particles from the computer. 2. The enclosure of claim 1 wherein the reclosable seal is secured along the back side of the computer lid along the side edges. 3. The enclosure of claim 1 wherein the flexible flap includes edges wrapping around the side edges of the computer lid. 4. The enclosure of claim 1 wherein the gas permeable vent portion and the reclosable seal restrict flow of contaminant particles larger than 0.5 microns in size. 5. The enclosure of claim 1 further including a reclosable seal for securing the flexible sleeve opening to restrict flow of contaminant particles. 6. The enclosure of claim 1 wherein the flexible flap extends from the flexible sleeve adjacent the sleeve opening. 7. The enclosure of claim 1 wherein, except for the transparent panel portion, the gas permeable vent portion comprises a substantial portion of the flexible sleeve. 8. The enclosure of claim 1 wherein, except for the gas permeable vent portion, the flexible sleeve comprises a substantially gas impermeable material. 9. The enclosure of claim 1 wherein the flexible flap includes a gas permeable vent portion restricting flow of contaminant particles. 10. The enclosure of claim 1 wherein the transparent panel portion for viewing and operating the keyboard is non-breathable. 11. The enclosure of claim 10 wherein the reclosable seal is adjacent opposite side edges of the lid between the front and back sides. 12. The enclosure of claim 11 wherein the reclosable seal is secured along the back side of the computer lid along the side edges. 13. The enclosure of claim 11 wherein the flexible flap includes edges wrapping around the side edges of the computer lid. 14. The enclosure of claim 10 wherein the gas permeable vent portion and the reclosable seal restrict flow of contaminant particles larger than 0.5 microns in size. 15. The enclosure of claim 10 further including a reclosable seal for securing the flexible sleeve opening to restrict flow of contaminant particles. 16. The enclosure of claim 10 wherein the flexible flap extends from the flexible sleeve adjacent the sleeve opening. 17. The enclosure of claim 12 wherein, except for the transparent panel portion, the gas permeable vent portion comprises a substantial portion of the flexible sleeve. 18. The enclosure of claim 10 wherein, except for the gas permeable vent portion, the flexible sleeve comprises a substantially gas impermeable material. 19. The enclosure of claim 10 wherein the flexible flap includes a gas permeable vent portion restricting flow of contaminant particles.
