Abstract A hollow vertical cylinder is open at its lower end. A deck having an open communicating with the interior of the cylinder seals the upper end of the cylinder. A cap for the upper 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 along a portion of its periphery to a corresponding portion of the upper end periphery by an integral living hinge. The two sections have adjacent edges disposed along a curved line which extends across the deck, these edges being secured to each other at opposite ends of the line and being otherwise unsecured to each other. The secured edges at each end of the line each constitute a separate integral living hinge. The first section is secured to the top end in a region spaced from both hinges. A prong is secured to the second section and is insertable into and removable out of the opening in the deck.
A plastic device adapted to engage and close the open neck of a container and comprising: a vertical hollow cylinder open at its lower end; a deck sealing the upper end of the cylinder, the deck having an opening communicating with the interior of the cylinder; a cap for the upper end, the cap having essentially the same shape and area as the upper end, the cap consisting of a first relatively small section and a second relatively large section, the first section being secured along a portion of its periphery to a corresponding portion of the periphery of the upper end by an integral living hinge, the two sections having adjacent edges disposed along a curved line which extends across the deck, these edges being secured to each other at opposite ends of the line and being otherwise unsecured to each other, the secured edges at each end of the line each constituting a separate living hinge; interconnecting means on said deck and said first section, spaced from all of the living hinges, securing the first section to said deck; and a prong secured to the second section and extending at right angles thereto, the prong being insertable into and removable out of the opening in the deck.
