发明名称 Squeeze bulb for liquid extraction device
摘要 A squeeze bulb for use on a liquid extraction device includes a collapsible wall structure formed of a flexible, resilient rubber; the wall structure being shaped and configured to include a main bulbous portion surrounding an interior chamber and an integral neck portion extending from the bulbous portion and terminating at an annular rim surrounding an open end. A passage extends through the neck portion, from the open end to the interior chamber, in fluid communication therebetween and is sized and configured for removable, snug-fitted receipt of a proximal end zone of an elongate tube of the liquid extraction device, in sealed relation therein. Stand-up supports provided at spaced intervals about the annular rim support the squeeze bulb in an upright position on a flat surface, when removed from the elongate tube, so that the annular rim is maintained in spaced relation above the flat surface to define ventilation gaps, permitting liquid to drain from the bulb interior and allowing air flow through the passage of the neck and to the interior chamber, thereby promoting drying of moisture within the squeeze bulb.
