摘要:
A water soluble film useful in unit-dose chemical packaging is disclosed. The film may include: a water soluble saccharide and a polyvinyl alcohol copolymer consisting essentially of: (a) from 80 to 99 mole percent of vinyl alcohol and vinyl ester monomer; and (b) from 1 to 20 mole percent of a pyrrolidone comonomer. Such compositions may be used to provide a water-soluble film simultaneously satisfying requirements in regard to water solubility, biodegradability, and physical properties, even when used for packaging of harsh, oxidizing chemicals.
摘要:
A pouch for containing a product is formed of water dispersible or water dissolvable paper on the exterior and a water dissolvable adhesive on the interior. The method of manufacturing includes folding a sheet of paper about a central fold line such that adhesive applied thereto is on the interior and engages adhesive on the opposite side of the fold line. The adhesive adjacent the side edges is sealed to form seams at such side edges. After filling, the top edge may be sealed to form the completed pouch.

摘要:
A detergent multi-compartment pouch having a plurality of water-soluble films forming a plurality of compartments the pouch comprising two side -by-side compartments superposed onto another compartment wherein at least two different compartments contain two different compositions.
摘要:
This invention relates to container containing a dose of a liquid cleaning composition for use in a ware washing machine, wherein said container is adapted to be disposed in a ware washing machine in a predetermined orientation and wherein said container comprises a low-level opening for permitting egress of the cleaning composition from the container (when disposed in said predetermined orientation), and wherein the container is of a water-insoluble plastics material and wherein the low-level opening is closed by water-soluble plastics closure member. The dosage element and chamber are particularly useful in the context of forming part of a multi-dosing cleaning composition delivery device and/or a refill for such a device.
摘要:
A dosage element of a type to be consumed in use in a ware washing machine comprises an outer casing (10) formed during a preliminary manufacturing process, whereby said outer casing is provided with two compartments respectively containing first and second substances, the two compartments being separated by an insert (20) which forms one or more internal separation walls.
摘要:
This invention concerns dosage elements for a ware washing machine and a method of manufacturing such dosage elements. In embodiments of the invention a dosage element comprises first (10) and second (20) joined parts, wherein the first part (10) is a part which, prior to joining with the second part (20), comprised an open receptacle and wherein the second part (20) comprises a substrate carrying a plurality of mutually separated substances A, B, C arranged in side by side relation. The second part (20) is joined to said first part (10) so as to close said receptacle and enclose said substances within it. Dosage elements produced in the inventive method are pleasant to handle, whilst being surprisingly resistant to. damage in handling or transit.
摘要:
A water-soluble substrate (10), and more particularly a water-soluble substrate that is resistant to contact with small amounts of water, and methods of making the same are disclosed. At least one of the substrate's surfaces (12, 14) comprises first discrete zones (20) having a water- solubility which is less than the water-solubility of said water-soluble substrate. The first discrete zones (20) represent from 10% to 90% of the surface area of said first or second surface.
