In a method for the pressure-tight packaging of articles, in particular tennis balls, in a container, an initially solid or liquid substance which subsequently evolves gas or is converted to the gaseous phase is metered into the respective container, before the tight closure thereof, in a quantity corresponding to the desired internal pressure of the container. This method can be carried out in an extremely simple and problem-free manner and permits a relatively large freedom in respect of the choice of container shape and container material. It is possible for the internal pressure of the container to be controlled in a defined manner without additional outlay on complicated devices which increase the cost of the packaging.
