Claims
1 A protective article comprising a sheet with a first surface and a first adhesive portion and a second adhesive portion arranged on the first surface, wherein each adhesive portion comprises a water-based acrylic adhesive that allows the sheet to be non-permanently adhered to an object, wherein the sheet is folded such that a first portion of the first surface faces a second portion of the first surface, the first adhesive portion and the second adhesive portion engage each other, the water-based acrylic adhesive being selected such that it is of a type that will allow the first and second adhesive portions to be separated when the sheet is unfolded, in use, and allow the sheet to be adhered to an object, wherein none of the adhesive portions are covered at least partially by a removable cover or backing strip.
2. A protective article comprising a sheet with a first surface and an adhesive portion arranged on the first surface, wherein the adhesive portion comprises a water- based acrylic adhesive that allows the sheet to be non-permanently adhered to an object wherein the sheet is folded such that a first portion of the first surface faces a second portion of the first surface, the adhesive portion arranged on the first portion of the first surface is brought into engagement with the second portion of the first surface at a location absent the adhesive portion, the water-based acrylic adhesive being selected such that it is of a type that will allow the adhesive portion arranged on the first portion of the first surface and the second portion of the first surface to be separated when the sheet is unfolded, in use, and allow the sheet to be adhered to an object, wherein none of the adhesive portions are covered at least partially by a removable cover or backing strip.
3. A protective article according to claim 1 or claim 2, wherein the water-based adhesive comprises at least 40 parts by weight of a water-based acrylic emulsion and/or up to 90 parts by weight of a water-based acrylic emulsion.
4. A protective article according to claim 1, claim 2 or claim 3, wherein the or each adhesive portion is sprayed, rolled, printed or stamped on to the first surface of the sheet.
§. A protective article according to any one of the preceding claims, wherein the or each adhesive portion has a polygonal shape or a curvilinear shape having one or more curved sides, optionally wherein the or each adhesive portion has the form of an elongate strip, optionally wherein at least a portion of the elongate strip is straight, zig-zagged, curved or wavy.
6. A protective article according to any one of the preceding claims, wherein the water-based adhesive is coloured by the addition of one or more colouring agents, dyes and/or pigments.
7. A protective article according to any one of the preceding claims, wherein the sheet is folded prior to application of adhesive.
8. A protective article according to any one of the preceding claims, wherein the sheet is folded more than once.
9. A protective article according to any one of the preceding claims, wherein one or more adhesive portions are arranged on a second surface of the sheet.
10. A protective article according to any one of the preceding claims, wherein the sheet is made from card, cloth, woven fabric, non-woven fabric, plastic, or single or multiple plies of paper.
11. A protective article according to any one of the preceding claims, wherein the protective article comprises a napkin, a dental napkin, a napkin for medical use, a surgical napkin, an apron, a bib, a table cloth, a coaster, a place mat, a furniture cover for indoor or outdoor use or a windscreen cover for a vehicle.
Zz A method of manufacture of a protective article, the method comprising the steps of:
providing a sheet with a first surface; and
applying a first adhesive portion and a second adhesive portion on to the first surface;
wherein the first and second adhesive portions comprise a water-based acrylic adhesive that allows the sheet of material to be non-permanently adhered to an object; and
folding the sheet such that the first adhesive portion is brought into engagement with the second adhesive portion, wherein none of the adhesive portions are covered at least partially by a removable cover or backing strip.
13. A method of manufacture of a protective article, the method comprising the steps of:
providing a sheet with a first surface; and
applying an adhesive portion on to the first surface;
wherein the adhesive portion comprises a water-based acrylic adhesive that allows the sheet of material to be non-permanently adhered to an object; and
folding the sheet such that the adhesive portion is brought into engagement with an adhesive-free portion of the first surface, wherein none of the adhesive portions are covered at least partially by a removable cover or backing strip.
14. A method according to claim 12 or claim 13, wherein the adhesive portion(s) is/are applied on to the first surface from either side of the sheet.
15. A method according to claim 12, claim 13 or claim 14, wherein applying the at least one adhesive portion on to the first surface comprises spraying, rolling, printing or stamping the water-based adhesive.
16. A method according to any one of claims 12 to 15, wherein the water-based adhesive comprises one or more colouring agents, dyes and/or pigments.
17. A method according to any one of claims 12 to 16, the method comprising the step of initially folding the sheet before the application of the adhesive.
18. A method according to any one of claims 12 to 17, wherein the adhesive portion(s) is/are applied to form a strip of adhesive extending a distance along the first surface.
19. A method according to any one of claims 12 to 18 comprising the step of drying the at least one adhesive portion, optionally wherein drying the at least one adhesive portion comprises applying heat from a heat source, optionally wherein the heat source comprises an infra-red heat source.
20. A method according to any one of claims 12 to 19, the method comprising varying the rate of application of the water-based adhesive, optionally the method comprising varying the properties, e.g. chemistry, composition and/or colour, of the water-based adhesive.
