ABSTRACT:
The present invention provides an improved closure for ESD bags which provides an effective closure without causing the generation of additional charges nor blocking of the visibility of the component in the bag. More significantly, the present invention provides an effective yet easy to use closure which does not cause injury or irritation to the fingertips or fingernails of the ESD worker. The invention includes a pair of elongate rails which are substantially parallel when in a closed position. Support means are provided between the rails and a hinge for permitting the rails to move from the closed position to an open position. A latch slideable between a first closed position and a second open position maintains the rails in close relation when the invention is in use. The sliding motion of the latch obviates the necessity to pry open a snap as was necessary with the snap-stick of the prior art. In a particular embodiment, the supports are notched to assist in the maintenance of the closure. Further provided in a specific embodiment is an elongated ridge on one rail and a corresponding groove or trough on the other which assist in the closure of the bag. A yet more specific embodiment includes a handle for grasping or holding the closure.
