摘要:
It has for some years been proposed to package chemicals such as herbicides and pesticides in a flexible pouch which is made of a water soluble material such as PVOH. The pouch is disposed within a flexible water-protective bag, and the bag is then given an outer holder, commonly of corrugated board or the like, to provide additional strength and some protection against the likely ambient conditions. Such a triple-layer package is easy and safe to use, but has some disadvantages, namely that the present outer holder does not seem to hold the bag properly, so that if the bag-disposed pouch becomes brittle it is too easily susceptible to damage from mechanical shock. The present invention proposes a solution to this, in which the pouch/bag combination is given an outer holder of a novel form which provides significantly enhanced protection against shock. More specifically the invention suggests the use, as the outer portion of the three-layer package, of a pillow-shaped open-ended sleeve-like holder made from a suitably-shaped and -cut blank (1) that has been folded in such a way as to grip the bag securely and also preferably to provide the holder with cuff-like strengthening and shock-absorbing members (24, 26) around the two end edges of the sleeve. The sleeve is kept closed by a closure flap (18) the corners (20) of which are conveniently inserted into the space between the cuff members (24, 26) and part of the sleeve body (4).

A security label (1) has a bar code (2) printed on the outer surface of an outer layer (6) which is permanently bonded to an inner layer (7). A pull tab (3) defined in the material of the outer and second layers (6 and 7) is joined to a detachable portion (4) extending across the length of the label (1) whereby removal of the pull tab (3) will tear out the detachable portion (4) to prevent recognition of the optically readable pattern.

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.
摘要:
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).

A blank (1) from which may be erected a protective enclosed tamper evident container (2) for the packaging of articles during transportation and storage. The blank (1) has five aligned panels (A, B, C, D, E) that form opposed roof and floor walls of dome shape connected at opposite ends of the container (2) by side walls of concave shape. The centre panel (C) forming the floor wall has opposed closure panels (F, G) that fold over the roof wall to close the open sides of the container (2) and are provided with locking tongues (H) that engage slots (16) in the roof wall to secure the container (2). The tongues (H) and slots (16) provide a tamper evident mechanism for securing the container (2) such that no adhesive is required during the erection process in order to hold the container in its closed position.

This invention relates to a novel package, particularly for use as a skin package which may be readily recycled, and to a process for preparing such a package.
摘要:
This invention relates to the delivery of active ingredients to plants or cut plants and to the repair of damaged, spliced or grafted plants in which both healing materials and mechanical support are brought to the site of the wound, splice or graft by means of a water-soluble or water-dispersible bandage or wound dressing, in particular, but not exclusively, a water-soluble or water-dispersible self adhesive tape or label. The active ingredient or ingredients are transmitted safely and efficaciously to the plant without contaminating the user, the environment, neighbouring plants or crops, and the water-soluble or water-dispersible bandage or wound dressing will, over time, dissolve, become absorbed by the plant, or disperse either whilst still attached to the plant or in a subsequent composting process.

Thermoformed water-soluble packages are known, but some suffer from "shrink-back", which prevents the volume of a formed cavity being fully utilised at the filling stage. To overcome this the present invention proposes a packaging system wherein each individual container (25) of a multiplicity of such containers all joined together in a group side by side in a web comprises an inner water-soluble or dispersible encapsulate (25) enclosed wholly within and thermoformed simultaneously with a protective external water-insoluble casing (19, 11), and each of the encapsulate and the casing is, separately, in the form of a thermoformed hollow body and a lid (23) and is made from two films (15, 12 and 19, 11) bound together by one common seal, so that each encapsulate is in contact only with the inner wall of its casing.

The present invention provides a vented cushion pack 1 which is either biodegradable allowing subsequent composting, or water- soluble/dispersible allowing subsequent repulping, methods of making such packs and the use of such packs to protect packaged goods. The cushion pack (1) has vents (5) to allow air to escape from within the pack to provide pneumatic cushioning when the pack (1) is compressed, and contains a corrugated fibreboard lattice (3) that is resiliency deformable to provide physical cushioning when the pack (1) is compressed and allows the pack (1) to return at least partially to its original shape when the compression is removed.
摘要:
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 the ingredient(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).
