Abstract
A dispensing bulb having a squeezable body portion and integral squeezable neck portion having a pair of diametrically disposed vent holes. An adaptor is mounted in the neck portion and is provided with a cylindrical portion extending into the bulb neck portion beyond the vent holes and spaced radially inwardly therefrom. A dispensing tube is connected to the adaptor and communicates with the interior of the bulb. The neck portion of the bulb is squeezed to draw liquid into the tube, and the cylindrical portion of the adaptor limits the squeezing of the neck portion to prevent liquid from being drawn through the tube into the body portion of the bulb.
