76results about "Envelope openers" patented technology

There is provided a portable letter opener that is capable of transitioning between an open and a closed position. The letter opener includes a first housing section, a second housing section, a blade, and a pin forming a pivot hinge so that the first housing section and second housing section can move between the open and closed positions. The first housing section defines a slot such that the blade is at least partially positioned within the slot of the first housing section when the portable letter opener is in the closed position. The first housing section may also define an aperture for connecting with a key chain. Both the first housing section and the second housing section may define a pair of tab with a hole therein for receiving the pin. The blade, connected to the second housing section, is at least partially exposed when the portable letter opener is in the open position, and the blade has a sharpened edge capable of slicing open a sealed envelope flap. The first housing section and second housing section may have complementary stop surfaces and rest surfaces whereby contact between the stop surface and rest surface limit movement of the letter opener past the open position. Similarly, the first and housing section have complementary surfaces which come into contact when the letter opener is closed. The blade is preferably positioned well within the opening of the letter opener for safety reasons and is set at a slant for easily slicing open envelopes.
