State of the art

Many utensils and / or massage devices are available and sold. Their applications differ from each other and may relate, for example, to muscle relaxation, for example for use by physiotherapists, osteopaths, etc.

There are also massage devices to improve the appearance of the skin. It can be for example a device for the treatment of cellulite and / or the orange peel appearance. The known and commonly used devices are based on the principle of a massage by vibration and / or by "palpate rolling". Examples of devices marketed include the Ardes ARD and the M240Solac ME7711. The usual devices are electrical devices requiring a current source for their uses. In addition, these devices are complex and expensive, thus limiting their accessibility and use. In addition, these devices are bulky and bulky.

There is therefore a real need to find a new massage device overcoming these faults, drawbacks and obstacles of the prior art, in particular a simple device, not requiring a source of energy, in particular electric, capable of being used. without restraint.

There are also in the prior art massage devices, for example manual massage suction cups, for example as described in patent application EP2853250, based on a suction phenomenon. However, known massage devices require the application of the device and therefore manual massage for a minimum time, for example 5 minutes, in order to be efficient.
