Abstract
A delivery device for a sanitary article includes an encapsulating material with a first layer and a second layer, enclosing an additive in a space formed by these layers of encapsulating material. The delivery device also includes a third layer, positioned above the second layer of encapsulating material. The third layer extends beyond and thereby covers substantially all of the edges of the second layer of encapsulating material. The third layer may also extend into and throughout the space formed between the first and second layers of encapsulating material that enclose the additive. The third layer thereby protects the user of a product comprising the delivery device from contact with the edges of the second layer of encapsulating material and also provides a means for attaching the delivery device to an article to keep it in place during transport storage and use. The invention also relates to sanitary articles, such as hygiene tissues and absorbent articles, containing the delivery device.
