US Classification:

Abstract:

The Trash Bag Separator, as the name implies is an apparatus to aid in the initial opening of plastic bags such as grocery bags and trash bags. The Trash Bag Separator resembles a plastic credit card folded in half, with adhesive edge paper on each of the inner sides, with the sticky strip on the outer edge. To use the invention, the user places the “book” over the open end of the bag and closes it. The spring nature of the binding causes the “book” to open when released. The sticky paper then separates the two halves of the bag allowing it to be open with ease. The bag can then be removed from the Trash Bag Separator, and the invention is ready to reuse on the next bag.

Abstract:

A radio or telephone handset configured with the usual transmitter and receiver ends and connecting handle is designed to have physical characteristics well adapted in its acoustic characteristics to complement noise cancellation circuitry. The receiver speaker is mounted in the receiver cap, and the cap is built with a domed, apertured earpiece extending from the exterior surface of said receiver cap. The dome fits into a user's outer ear, thereby to aid in positioning said handset on a user's ear. Openings radially placed on said receiver cap exterior surface and surrounding said earpiece, define an acoustic grill through which signal from said receiver speaker is passed substantially directly to said user's ear canal. Noise absorbing material is placed at strategic locations within the handset interior.
