Claims

1. A method of manufacturing a non-rigid container, the method including the following steps: coating a surface of a fabric with a water-based adhesive; leaving the product to cure for a predetermined period of time; temporarily adhering a paper to said adhesive surface of said fabric in a heat fusing press; cutting one or more required pattern pieces; stitching said one or more patters pieces together in a desired fashion; and coating said material with a hydrophobic coating.

2. A method as claimed in claim 1, wherein said fabric is provided in the form of a 100% cotton calico 135 gsm or poly-cotton blend, weave or twill.

3. A method as claimed in claim 1, wherein said paper is provided in the form of sack craft paper manufactured from a medium to low refined long fiber kraft pulp, with refining at high and forming a low consistency, granting fiber-to-fiber bonding with a high porosity.

4. A method as claimed in claim 3, wherein said paper is dried with loose draws, allowing it to shrink in the dryer.

5. A method as claimed in claim 3, wherein said paper is provided in the example form of 80 and 85 gsm extensible sack kraft paper, bleached or unbleached.

6. A method as claimed in claim 1, wherein said method includes the step of printing a pattern or design on said paper.

7. A method as claimed in claim 6, wherein said printing includes screen printing, digital flatbed printing or stamping with one or more of the following: an alcohol-based ink, a specialised textile ink, a permanent archival ink or an oil-based ink.

8. A method as claimed in claim 6, wherein said method includes the step of drawing on said paper using a permanent marker such as a Sharpie pen or Artline pen.

9. A method as claimed in claim 6, wherein said method includes the step of painting on said paper using a non-water-based paint such as an Acrylic Drawing Ink.

10. A method as claimed in claim 6, wherein said method includes the step of debossing, embossing and/or foiling said material.

11. A method as claimed in claim 1, wherein said water-based adhesive is provided in the example form of a thermal acrylic polymer water-based adhesive.

12. A method as claimed in claim 1, wherein said step of coating a surface of a fabric includes passing said fabric through a roller process where a pressure of 80 pounds/square inch is applied to the fabric at 100 degrees Celsius.

13. A method as claimed in claim 12, wherein said method includes the step of peeling a plastic sheet of said adhesive surface of said fabric.

14. A method as claimed in claim 1, wherein said heat fusing of said fabric and paper takes place at a pressure of between 1 Bar and 3 Bar.

15. A method as claimed in claim 14, wherein said heat fusing of said fabric and paper takes place at a temperature of between 100 and 120 degrees Celsius.

16. A method as claimed in claim 1, wherein said step of coating said material includes spraying said material with a hydroponic liquid repelling coating, in the example form of Nano Technology Textile Coating or Nano Silicon Dioxide (SiO2).

17. A method as claimed in claim 16, wherein said coating is water-based, free from alcohol and is harmless to the skin and environment in that it contains no harmful substances.

18. A method as claimed in claim 17, wherein said environmental friendly nature of said coating is verified independently in accordance with the Oeko-Tex Standard 100.

19. A method as claimed in claim 18, wherein said step of coating said material includes the step of spraying said coating onto the surface with a high-pressure gun, the nanoparticles form a ultra-thick non-polymer based matrix and bonds with the surface, so as to protect it from oil, water an dirt.

20. A non-rigid container wherein said non-rigid container including one or more of the following: a holder, cover or bag manufactured form a material including a bonded paper and fabric; wherein said holder, cover or bag is manufactured according to a method of manufacturing a non-rigid container, as described with reference to embodiments of this invention.

DESCRIPTION OF PREFERRED EMBODIMENT

[0038] The following description of the invention is provided as an enabling teaching of the invention. Those skilled in the relevant art will recognise that many changes can be made to the embodiment described, while still attaining the beneficial results of the present invention. It will also be apparent that some of the desired benefits of the present invention can be attained by selecting some of the features of the present invention without utilizing other features. Accordingly, those skilled in the art will recognise that modifications and adaptations to the present invention are possible and can even be desirable in certain circumstances and are a part of the present invention. Thus, the following description is provided as illustrative of the principles of the present invention and not a limitation thereof.

[0039] In FIG. 1, a method of manufacturing a non-rigid container, is generally described with reference to numeral 100.

[0040] The method 100 includes the step of coating a surface of a fabric with a water-based adhesive, at block 102. The fabric is then interleaved with plastic film, at block 102.1 and left to cure for 24 hours, at block 102.2.

[0041] At block 104, the method 100 includes the step of adhering a paper to an adhesive surface of fabric using heat.

[0042] At block 106, the method 100 includes the step of cutting the fabric into pattern pieces.

[0043] At block 108, the method 100 includes the step of stitching the fabric together.
