ABSTRACT:
A pressurizing cap for a conventional tennis ball container includes a sleeve that defines an internal sealing surface shaped to seal against a lip defined by the tennis ball container as the sleeve is moved axially along a stroke when the sleeve is applied to the container. The pressurizing cap includes an end panel sealed to a closed end of the sleeve and the cap defines an annular recess adjacent to the sealing surface near the end panel. This recess is shaped to receive the annular lip and to hold the cap releasably in place on the container. The cap can be placed on the container and then moved axially into position on the container without rotation. The sliding seal created between the lip of the container and the internal sealing surface causes movement of the cap toward the container to pressurize the container.
