Abstract

A method of manufacturing a custom sized plastic tote lighter in weight than heretofore known custom sized plastic totes is provided. The method comprises separating an injection molded tote into upper and lower portions by cutting the injection molded tote. A sleeve or middle portion of plastic material is secured to the upper and lower portions of the injection molded tote to create a custom sized plastic tote of a desired height. Alternatively, portions of different injection molded totes may be used to create a custom sized plastic tote. The sleeve may be made from different materials and may be made of multiple pieces.

First claim

The invention claimed is:

1. A method of manufacturing a custom sized plastic tote comprising:
cutting an injection molded tote having sidewalls, an upper lip, a lower lip and a floor to create a rail including the upper lip of the injection molded tote and a tray including the lower lip and floor of the injection molded tote;
separating the rail and tray of the cut injection molded tote;
securing a four-sided sleeve made of corrugated plastic to sidewalls of the rail and tray with mechanical fasteners to form a custom sized plastic tote having an upper portion, a lower portion and a sleeve extending therebetween.

2. The method of claim 1 wherein said sleeve is riveted to said upper and lower portions of the custom sized plastic tote.

3. The method of claim 1 wherein the corrugations of said sleeve are vertically oriented.

4. The method of claim 1 wherein the sleeve is made of one piece of material having opposed side edges joined together.

5. The method of claim 1 wherein said sleeve is made from multiple pieces of material.

6. The method of claim 5 wherein said sleeve is made from two pieces of material.

7. The method of claim 1 wherein the upper portion of the custom sized plastic tote has handles.

8. The method of claim 1 further comprising removing exterior protrusions of the injection molded tote.

9. The method of claim 1 wherein said sleeve is made of polyethylene.

10. A method of manufacturing a custom sized plastic tote comprising:
cutting an injection molded tote having sidewalls, an upper lip, a lower lip and a floor to create a rail including the upper lip of the injection molded tote and a tray including the lower lip and floor of the injection molded tote;
separating the rail from the tray of the cut injection molded tote;
securing a four-sided sleeve made of a trilaminate material to sidewalls of the rail and tray of said cut injection molded tote to form a custom sized plastic tote having an upper portion, a lower portion and a sleeve extending therebetween.

11. The method of claim 10 wherein the upper portion of the custom sized plastic tote has handles.

12. The method of claim 10 further comprising removing exterior protrusions of the injection molded tote.

13. The method of claim 10 wherein the sleeve is made of a pair of face plies and a middle ply having a plurality of dimples.

14. The method of claim 10 wherein the sleeve is made of one piece of material having opposed side edges joined together.

15. The method of claim 10 wherein said sleeve is made from multiple pieces of material.

16. The method of claim 10 wherein said sleeve is secured to the upper and lower portions of the custom sized plastic tote with mechanical fasteners.

17. The method of claim 10 wherein said sleeve is made of polypropylene.

18. A method of manufacturing a custom sized plastic tote comprising:
cutting a first injection molded tote having sidewalls, an upper lip, a lower lip and a floor to create a rail including the upper lip of the injection molded tote and a tray including the lower lip and floor of the injection molded tote;
separating the rail from the tray of the cut injection molded tote;
securing a four-sided sleeve of corrugated plastic to sidewalls of the rail and tray of said cut injection molded tote to form a custom sized plastic tote having an upper portion, a lower portion and a sleeve extending therebetween.

19. The method of claim 18 wherein said sleeve is riveted to said upper and lower portions of the custom sized plastic tote.

20. The method of claim 18 wherein the corrugations of said sleeve are vertically oriented.

21. The method of claim 18 wherein the sleeve is made of one piece of material having opposed side edges joined together.

22. The method of claim 18 wherein said sleeve is made from multiple pieces of material.

23. The method of claim 18 wherein said sleeve is secured to the upper and lower portions of the custom sized plastic tote with mechanical fasteners.

24. The method of claim 18 wherein the upper portion of the custom sized plastic tote has handles.

25. The method of claim 18 further comprising removing exterior protrusions of the injection molded tote.

26. The method of claim 18 wherein said sleeve is made of polyethylene.
