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.

Claims

1. An improved closure for electrostatic bags, said closure having a closed position and an open position and comprising:

first and second substantially flat elongate rails which are substantially parallel when said closure is in said closed position;

support means having generally V-shaped configuration attaching said first and second flat elongated rails to a hinge means respectively for permitting said rails to move from said closed position to said open position;

latch means for maintaining said rails in said closed position, said latch means slideable between a first closed position and a second position for opening of said closure whereby said closure operated by the translation of said latch therebetween;

said first and second rails having flat mating areas for clamping said electrostatic bags;

said first rail having at least one elongated protrusion and said second rail having at least one corresponding elongated recess in alignment therewith when said closure is in said closed position; and

said closure being formed of a material having good anti-static properties, and more specifically having a resistivity equal to or less than that of the anti-static range of materials;

said V-shaped support means and said hinge means being formed of a single unitary member having a substantially constant resistivity equal to or less than that of the anti-static range of materials;

said V-shaped support means including two supports each of which has a notch on its outer surface for engagement by said latch means; and

a handle means attached to said V-shaped support means and extending generally transversely therefrom for grasping and holding said closure, and for retaining said latch means as part of the closure assembly.

2. A closure as defined in claim 1 wherein said closure is formed of plastic material having a resistivity equal to or less than that of the anti-static range of materials.
