Abstract
Abstract Squeeze bottle pumpless nozzle dispenser has a first lid, a second lid, a dispensing nozzle, a shut off valve and a dip tube. The first lid, located on the top, has a dispensing orifice upper portion and a venting orifice upper portion. Each of these is located in either a track or a track follower formed in the bottom of the first lid and in alignment therewith. It has means for rotatable attachment to the second lid. The second lid has means for attaching to the squeeze bottle and includes the lower portions of a dispensing orifice and a venting orifice. Each of these is located in either a track or track follower and is located on the top of the second lid in alignment with the counterparts located on the bottom of the first lid. A shut off valve is located within the lower or upper portion of the venting orifice, responsive to pressure. When the bottle is squeezed, the shut off valve will close the vent so that fluid material will only exit through the dispensing orifice and thus through the nozzle. The first lid may be placed in a first position where neither the upper portion of the dispensing orifice nor the upper portion of the venting orifice is in alignment with its lower portion. When the first lid is rotated to a second position, there is simultaneous alignment of the upper and lower portions of both the dispensing orifice and the venting orifice.
