This invention concerns a hollow polyolefin ball containing an entectic coolant mixture with a screwed- or glued-on sleeve or handle for massage of the skin with a view to obtaining a vasoconstrictor effect in the epidermis. The invention can also be used to sooth local pain. According to Figure 3 the invention is characterized by a polished polyolefin sphere (1) containing an entectic mixture which is introduced through the orifice (3). A shell (5) serving as housing closes the refrigerated ball with a screw-on ring (6) making it possible to grasp the device with maximum effectiveness for massage.

Why it's free to use
- Filed July 3, 1990 and granted January 12, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 3, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 3, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
