ABSTRACT:
A container or the like for cleaning preparations comprising a fused closure which consists of a stopper disposed in a closure hole of the container and made of a material which melts at a predetermined temperature and which releases the closure hole for the exit of product packaged in the container. A ring of which the thickness increases radially inwards towards the axis of the hole is integrally formed with the inner peripheral surface of the closure hole. The position and shape of the stopper are stabilized by a film applied by sealing to the outside of the closure hole. The walls of the container are flexible to accomodate changes in pressure inside the container.
