Abstract: A connecting device for attaching a lid to an insulated container. The connecting device has a barb arranged and configured to be inserted into a socket and to engage the walls of the socket upon rotation. The barb may engage the walls of the socket by displacing material or engaging receptors, such as threads, in the socket. The geometry of the barb is such that, after rotation, the barb remains connected to the body and lid without the aid of screws, rivets, or other means. The connecting device may also have a sliding or other connector for connecting the connecting device to the lid. The connector may be in the shape of a dovetail and the lid may have a recess configured to receive the dovetail.

Abstract: A personal air conditioning system that may be used, for example, to cool a tent. The personal air conditioning system includes a cooling lid that fits over a typical insulated cooler. The cooling lid includes a heat transfer tower that is configured to transfer heat from a cold medium, such as ice, that is located within the cooler to an area within the cooling lid. A heat sink is provided at the top of the heat transfer tower and at least partially within the cooling lid. A fan is configured to draw air into the cooling lid, across the heat sink, and out of the cooling lid. The cooled air may then be used for cooling of a tent or other compartment, for example, or may be directed to blow on an individual.

Abstract: A portable frozen drink machine that utilizes ice shaving technology for producing ice particles for a frozen drink. An ice hopper utilizing the ice shaving technology is connected by a common shaft to a mixer. The mixer is positioned below the ice hopper and extends into a beverage container. Ingredients for the frozen drink are put in the beverage container, and the ice particles fall downward from the ice hopper into the beverage container. The mixer stirs the ingredients, forming a well-mixed frozen drink.
