Abstract: A tree decorating system has a hanger device for a plurality of hanger elements which may be used for attachment to a plurality of elongated decorations. The hanger device has a plurality of hook elements spaced circumferentially from one another about an exterior side of a rigid annular body of the hanger device. Gripping elements with radial slots for tree branches extend inward from an interior side of the rigid annular body and form a central opening through which the top portion of a main stem of the tree stem may pass. The hanger elements have living hinges enabling formation of a respective pair of flaps thereon to move between open and closed positions relative to one another. The pairs of flaps have sets of complementary ribs thereon enabling the fastening of the flaps at the closed position and clamping of an end portion of an elongated decoration therebetween.

Abstract: An insert assembly for use in changing the temperature of a quantity of liquid contained in a bottle includes an end cap securable to the bottle, an elongated hollow insert member connected to the end cap and filled with a material provided at a temperature different from the quantity of liquid and adapted to extend downward from the end cap and into the quantity of liquid when the end cap is secured on the bottle, and a removable protective cover which encloses at least the insert member when the end cap is removed from the bottle to protect it from contamination. In one embodiment, the protective cover is an elongated protective sleeve removably fittable over the insert member and onto the end cap when the end cap is removed from the bottle so as to enclosed the insert member. In another embodiment, the protective cover includes a carton having a body open at one end and a lid for opening and closing the open end of the carton body.
