ABSTRACT:
The present invention relates to an improved apparatus for retaining a valve body in secure engagement with the valve neck of a pressurized container. The apparatus assembly of the present invention incorporates a unique design which makes the retaining arrangement tamperproof since the retaining ring or rings which keep the valve body in place within the valve neck cannot be removed through the use of any ordinary tool. It will take a special tool designed especially to remove the retaining ring or rings in order to accomplish the removal process. As a result, product safety is assured with a significant reduction in product liability.
