发明名称 PROTECTED SCREEN VENT
摘要 <p>A protected screen vent apparatus including an inverted cup with a downwardly extending side wall and a bottom opening. A tapped member extends between portions of the side wall to engage a nipple which extends downwardly through the bottom opening to the container or other structure being vented. The tapped member is spaced from other portions of the side wall to form ventilation passages therebetween extending from above the tapped member to the bottom opening. A perforate screen is vertically mounted in each passage to prevent insects and other foreign material from entering the container through the vent. The screen faces inwardly toward the downwardly extending nipple. The screen is securely snapped into place against opposed side wall grooves by bending the screen outwardly from inside the cup. The presence of the nipple within the cup shields the screen from mechanical damage.</p>
