ABSTRACT:
An improved synthetic resin dunnage element (10) for use in packaging and shipping of fluorescent tubes (76,78) is provided which is specifically designed to be of minimum fore and aft length while still providing maximum protection against tube breakage. The support (10) is of integral, thermoformed construction and advantageously includes alternating upwarding and downwardly opening and diverging wall sections (68,70,70a) with the fowardmost downwardly opening section (70a) being of lesser width, greater radius and vertically lower in position than the associated rearward sections (70). In this fashion the forwardmost sections (79a) engage the fluorescent tube end caps (82) whereas the sections 70 engage the glass tube body. Provision of such specialized, different downwardly opening wall sections (70,70a) allows the support (10) to be manufactured using substantially less starting sheet material as compared with prior supports.
