Abstract

Portable containers suitable for use as disposable contaminated material containers are provided. The containers include a top closure including first and second closure flaps whereby the first closure flap has a central opening for filling the box and a handle member for holding it. The handle member can be inserted into a corresponding aperture of the second closure flap which protects the handle from being contaminated during use. The design also includes using an interior space defined by an internal open-ended container wrapped in a preferred thermoplastic bag. This feature enables the container to resist leakage of contaminated materials and the risk of puncture of the container by sharp objects.

Claims

1. A portable container having a bottom closure and side panels, comprising:

a top closure comprising first and second closure flaps secured to opposite side panels of said container along respective hinge lines so that said flaps can be folded into over-lapping horizontal positions to close the container;

said first closure flap comprising a central opening therein and a handle member comprising a two-ply, folded extension of said first closure flap disposed on an edge of said first closure flap opposite its hinge line;

said handle member further comprising a biasing tab comprising a two-ply, folded extension of said first closure flap disposed to lie against an inner surface of the side panel connected to said second closure flap when said first closure flap is in a horizontal position;

said second closure flap comprising an aperture disposed to receive said handle member.

2. A portable container having a bottom closure and four side panels comprising:

a top closure comprising first and second closure flaps secured to opposite side panels of said container along respective hinge lines so that said flaps can be folded into over-lapping horizontal positions to close the container;

said first closure flap comprising a central opening therein and a handle member disposed on a side of said first closure flap opposite its hinge line; and

said second closure flap comprising an aperture disposed to receive said handle member and a hinged flap portion disposed to cover a portion of said aperture after said handle member is inserted therethrough.

3. The portable container of claim 2 wherein said hinged flap portion comprises an extended tab portion for inserting under said handle member.

4. The portable container of claim 3 wherein second closure flap comprises a locking tab disposed on a non-hinged edge of said second closure flap.

5. The portable container of claim 4 wherein said first closure flap comprises a slot for receiving said locking tab of said second closure flap.

6. The portable container of claim 5 wherein said first closure flap comprises a folding flap portion disposed to cover a portion of said central opening.

7. The portable container of claim 2 further comprising third and fourth closure flaps disposed on a remaining two of said four side panels.

8. The portable container of claim 7 wherein said third and fourth closure flaps comprise cutout portions which correspond to said central opening of said first closure flap when said first, third and fourth closure flaps are disposed into overlapping horizontal positions.

9. The portable container of claim 2 wherein said container further comprises a thin sheet of flexible material disposed to cover an inner surface of said container.

10. The portable container of claim 9 wherein said thin sheet of flexible material comprises a thermoplastic bag.

11. The portable container of claim 10 wherein said thermoplastic bag comprises polyethylene.

12. The portable container of claim 10 further comprising an open-ended container disposed within said thermoplastic bag.

13. The portable container of claim 12 wherein said openended container comprises a bottom and four side panels.

14. The portable container of claim 13 wherein said openended container is disposed with said thermoplastic bag to snugly fit into an inner cavity of said portable container.

15. The portable container of claim 14 wherein said thermoplastic bag comprises an extended open portion for disposing through said central opening of said first closure flap.

16. The portable container of claim 15 wherein said contaminated material is disposed within said open-ended container.

17. A portable contaminated material container formed from a one-sheet blank having a bottom closure and four side panels, comprising:

a top closure comprising four closure flaps secured to each side panel along a hinge line so that the four closure flaps can be folded into overlapping horizontal positions to close the container;

a first flap of said closure flaps comprising a central opening in open communication with an inner cavity of said container and further comprising a handle portion disposed on a side of said first closure flap opposite its hinge line;

a second flap of said closure flaps disposed opposite said first flap and comprising an aperture disposed to receive said handle portion of said first flap whereby said second flap is disposed to lie over substantially all of an exposed side of said handle portion and protect said exposed side of said handle portion from said contaminated material during filling of said container.
