Abstract: The invention is to provide a balloon cap structure that permits automatic inflation of a balloon with gas; a balloon that is provided with the cap structure and can be prevented from flying away after being inflated with gas for buoyancy; a balloon storage box for storing such balloons; and a balloon vending machine from which the balloons can be automatically dispensed one by one for distribution or for sale.

Abstract: A cotton candy making machine has a rotary pot having a rotation axis associated with a driving means, where a heater is included to heat sugar provided as a raw material and release the heated sugar in the form of floss-like threaded sugar from the rotary pot to the outside by rotating the rotary pot around the rotation axis by a rotary motion of the driving means; a basin to be rotated together with the rotary pot, in which the rotary pot is concentrically arranged; a raw material supplying means for supplying the sugar into the rotary pot; and a floss taking-up means that rotates around its rotation axis in a predetermined direction to take up floss-like threaded sugar released from the rotary pot. The rotation axis of the rotary pot and the rotation axis of the floss taking-up means form an intersection with each other at a predetermined angle.

Abstract: Disclosed is a cap plug for a balloon which includes a body mounted on a mouth portion of a balloon, an attachment connected to the body through a detachable connecting means and a yarn for connecting the body and the attachment. The connecting means has four outwardly directed engaging pawls provided on the body and an engaging groove provided in the attachment and engageable with the engaging pawls. The desired connection is achieved by moving each of the engaging pawls into the corresponding engaging groove, and relatively rotating the attachment and the body to bring the engaging pawl into firm engagement with the engaging groove. The engagement between the body and the attachment is released by rotation thereof in a direction opposite to that when they are connected.
