Abstract

The present invention relates to a shipping container for rolled goods, particularly relatively heavy and rigid rolled products such as high count rolls of trash bags. In at least one embodiment, the shipping container may be used for shipping a product enclosure containing a pair of rolled trash bags. The shipping container can include a pair of opposing side reinforcing trays to prevent damage to the shipping container when in transit. The invention can conserve the amount of materials used and reduce the shipping weight of the container. The shipping container can further include a flexible overwrap to maintain the reinforcement trays on the opposing side ends of the product enclosure and to provide for additional reinforcement to the shipping container.

First claim

I claim:

1. A shipping container comprising:
a product enclosure, the product enclosure comprising opposing vertical first and second side panels, opposing vertical front and rear panels, and opposing horizontal top and bottom panels,
at least a first rolled good within the product enclosure, a top of the first rolled good supporting the top panel and a bottom of the first rolled good resting on the bottom panel,
a first reinforcing tray, the first reinforcing tray comprising:
opposing horizontal top and bottom walls,
opposing vertical front and rear walls,
a vertical outer wall extending between first ends of the top, bottom, front, and rear walls, and
an opening extending between opposing second ends of the top, bottom, front, and rear walls, and

the first reinforcing tray receiving a first side end of the product enclosure, wherein the first side end comprises the first side panel and a first partial width of the top and bottom panels of the product enclosure.

2. The shipping container of claim 1 , wherein:
a flexible outer wrap is placed around an outer surface of the first reinforcing tray such that it encapsulates the product enclosure and the first reinforcing tray.

3. The shipping container of claim 2 , wherein:
the first reinforcing tray comprises a rectangular vessel and the product enclosure comprises a rectangular prism.

4. The shipping container of claim 3 , wherein:
the top and bottom of the at least one rolled good are generally flat, and
the flexible outer wrap is a single continuous web of polymeric film.

5. The shipping container of claim 4 , wherein:
the flexible outer wrap comprises shrink wrap film and the shrink wrap film is in intimate contact with the first reinforcing tray and the product enclosure.

6. The shipping container of claim 5 further comprising:
a second reinforcing tray, the second reinforcing tray comprising:
opposing horizontal top and bottom walls,
opposing vertical front and rear walls,
a vertical outer wall extending between first ends of the top, bottom, front, and rear walls, and
an opening extending between opposing second ends of the top, bottom, front, and rear walls,

the second reinforcing tray receiving a second side end of the product enclosure, the second side end opposite from the first side end, wherein the second side end comprises the second side panel and a second partial width of the front and rear panels and a second partial width of the top and bottom panels of the product enclosure.

7. The shipping container of claim 6 further comprising:
the flexible outer wrap placed around an outer surface of the second reinforcing tray and encapsulating the second reinforcing tray with the first reinforcing tray and the product enclosure.

8. The shipping container of claim 7 further comprising:
a second rolled good within the product enclosure, the second rolled good oriented about a second vertical axis and having a generally cylindrical shape, a generally flat top of the second rolled good supporting the top panel and a generally flat bottom of the second rolled good resting on the bottom panel.

9. The shipping container of claim 8 wherein:
the product enclosure comprises corrugated cardboard.

10. The shipping container of claim 9 wherein:
the first and second reinforcement trays comprise corrugated cardboard of equal or greater thickness than the corrugated cardboard of the product enclosure.

11. A shipping container comprising:
a product enclosure, the product enclosure comprising opposing vertical first and second side panels, opposing vertical front and rear panels, and opposing horizontal top and bottom panels,
at least a pair of rolled goods with corresponding outer walls proximate to each other within the product enclosure, the rolled goods oriented about first and second vertical axes, each rolled good having top and bottom surfaces,
the top surfaces of the pair of rolled goods supporting the top panel and the bottom surfaces of the pair of rolled goods resting on the bottom panel,
a first reinforcing tray, the first reinforcing tray comprising:
opposing horizontal top and bottom walls,
opposing vertical front and rear walls,
a vertical outer wall extending between first ends of the top, bottom, front, and rear walls, and
an opening extending between opposing second ends of the top, bottom, front, and rear walls,

the first reinforcing tray receiving a first side end of the product enclosure, wherein the first side end comprises the first side panel and a first partial width of the front and rear panels of the product enclosure.

12. The shipping container of claim 11 wherein:
the product enclosure comprises a rectangular prism and the first reinforcing tray comprises a rectangular vessel.

13. The shipping container of claim 12 wherein:
a flexible outer wrap is placed around an outer surface of the first reinforcing tray such that it encapsulates the product enclosure and the first reinforcing tray.

14. The shipping container of claim 13 wherein:
the flexible outer wrap is a single continuous web of polymeric film.

15. The shipping container of claim 14 wherein:
the flexible outer wrap comprises shrink wrap film, the shrink wrap film in intimate contact with the first reinforcing tray and the product enclosure.

16. The shipping container of claim 15 further comprising:
a second reinforcing tray, the second reinforcing tray comprising:
opposing horizontal top and bottom walls,
opposing vertical front and rear walls,
a vertical outer wall extending between first ends of the top, bottom, front, and rear walls, and
an opening extending between opposing second ends of the top, bottom, front, and rear walls,

the second reinforcing tray receiving a second side end of the product enclosure, the second side end opposite from the first side end, wherein the second side end comprises the second side panel and a second partial width of the front and rear panels and a second partial width of the top and bottom panels of the product enclosure.

17. The shipping container of claim 16 further comprising:
the flexible outer wrap placed around an outer surface of the second reinforcing tray and encapsulating the second reinforcing tray with the first reinforcing tray and the product enclosure.

18. The shipping container of claim 17 wherein:
the product enclosure comprises corrugated cardboard.

19. The shipping container of claim 18 wherein:
the first and second reinforcement trays comprise corrugated cardboard.

20. The shipping container of claim 17 wherein:
the first and second reinforcement trays comprise a generally rigid polymeric material.
