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.
A sanitary article comprising a delivery device for delivery of an additive, said delivery device comprising a first layer and a second layer of encapsulating material, said first layer being defined by first edges and said second layer being defined by second edges, said first layer being placed on a user facing side of the delivery device in relation to the second layer, said first layer and second layer of encapsulating material forming a space enclosing said additive, wherein the delivery device further comprises a third layer positioned on a user facing side of the second layer of encapsulating material, said third layer extending beyond and thereby covering at least substantially all of the second edges of the second layer of encapsulating material without covering all of the first layer of encapsulating material.
A sanitary article comprising a delivery device for delivery of an additive, said delivery device comprising a first layer and a second layer of encapsulating material, said first layer being defined by first edges and said second layer being defined by second edges, said first layer being placed on a user facing side of the delivery device in relation to the second layer, said first layer and second layer of encapsulating material forming a space enclosing said additive, wherein the delivery device further comprises a third layer positioned on a user facing side of the second layer of encapsulating material, said third layer extending beyond and thereby covering at least substantially all of the second edges of the second layer of encapsulating material, wherein the absorbent article comprises a top sheet, said delivery device being placed on said top sheet.
