  • Patent number: 8277940
    Abstract: A scent emitting patch remains securely attached to the skin of a wearer and is appointed for controlled release of scents. The patch is constructed having an external top layer and backing layer with a skin-contacting portion. The skin-contacting segment contains an adhesive. At least one reservoir comprising pockets or microcapsules containing a scent is disposed in at least one portion of the backing layer. These pockets or microcapsules are operative to rupture upon application of pressure or scratching by the patch wearer. Upon rupture, scent is delivered to the skin to emit aroma. Pockets containing the scent are formed in the backing layer. Microcapsules, if present, are preferably incorporated in the adhesive. A plethora of aromas are provided in the form of a perfume or cologne and correlating shapes can be used to form the patch. Scent is released at the skin-contact interface when pressure is applied ruptures the pockets or microcapsules, permitting controlled release at the wearer's election.

  • Patent number: 8267880
    Abstract: The invention relates to an elastic adhesive unidirectional bandage and to a method for the production and the use thereof. The inventive bandage is embodied in the form of a segment, exhibits elastic and adhesive properties and is designed, in particular for supporting joints and preventing and maximally reducing injuries in certain body regions. The bandage segment is held in position during a long time by means of the adhesive properties thereof and supports natural movements by the elasticity thereof without constrictions and folds. Even, when the bandage is carried for a long time, it does not provoke a foreign body feeling. The bandage segment is easily applicable and optimally anatomically adaptable by the specific design of the elastic areas (for example, only the partial areas of the segment are elastic) and by corresponding shape thereof.
