ABSTRACT:
A hollow vertical cyliner is open at its lower end. A deck having an opening communicating with the interior of the cylinder seals the upper end of the cylinder. A cap for the top end has essentially the same shape and size as the top end. The cap has a first relatively small section and a second relatively large section. The first section is secured to a corresponding portion of the top end. The two sections have facing edges which are spaced from each other except for a common central region which defines a second integral living hinge. A prong is secured to the second section and is insertable into and removable out of the opening in the deck.
