Abstract: A device for controlled delivery of an active ingredient to a receiving site (1) such as a plant, human or animal. The device comprises a filmic substrate including a water soluble carrier layer (2) disposed between first and second water soluble control layers (3, 4). The second control layer (4) of the filmic substrate is provided with adhesive (5) on the side remote from the carrier layer (2) for attaching the device to the receiving site (1) with the first control layer (3) outermost. The first and second control layers (3, 4) having perforated regions (9, 8) whereby the carrier layer (2) can be dissolved by wetting the first control layer (3) with an aqueous medium that passes through the perforations (9) of the first control layer (3) releasing the active ingredient into solution that passes through the perforations (8) of the second layer (4) to come into contact with the receiving site (1).

Abstract: The invention relates to dosing systems which involve water-soluble or water dispersible products containing ingredients embedded within and/or coated upon a water-soluble film which are released at a prescribed rate into an aqueous environment through one or more perforated less readily soluble water-soluble films. The dosing system can be used for delivering pharmaceutical active ingredients externally or internally to a human or animal body, and can be embodied in the form of a patch that is applied to a site to be treated via a water soluble adhering layer (1) that adheres to the site with ingredients(s) provided by a carrier layer (3) sandwiched between a perforated layer (2) for delivery of the ingredients to the site and a non-perforated protecting layer (4).

Abstract: A product containerisation system created by attaching at least one product (X) to one side of a planar sheet (103) by overlaying a polymeric film (101) over the product and one side of the planar sheet by a skin packing process, and there folding the planar sheet into an erected container or package, in which the polymeric film is selected and arranged such that twisting the product (X) and overlying film about an axis (105) transverse to the planar sheet shears the polymeric film generally around the perimeter (107) of the product adjacent the planar sheet.
