Abstract

A container for frangible articles comprising a tray molded in a sheet of polymeric material having a hinge portion separating a bottom portion from a cover portion with the cover portion being pivotable into engagement with the bottom portion to conceal the frangible articles in the container. The bottom portion comprises rows of cavities with each cavity adapted to support a frangible article. The cavities have lugs projecting inwardly and from bottom to top from a main surface of the cavity to support the frangible article while maintaining air gaps between the frangible article and the main surface. Corner cavities are positioned at opposite leading corners of the bottom portion and each have a protective rib oriented toward its respective leading corner and projecting outwardly from the main surface and from bottom to top to provide structural integrity to the opposite leading corners of the container.

Claims (26)

1. A container comprising a tray, the tray comprising:

an upper wall member defining a longitudinal axis and having a longitudinal edge parallel to the longitudinal axis and an end edge transverse to the longitudinal edge, the longitudinal edge and the end edge defining a corner of the tray;

a plurality of item-receiving cavities, each cavity having a bottom, an upper end, a frustoconical wall portion between the bottom and the upper end, and a cylindrical wall portion proximate the upper end, the plurality of cavities including a corner cavity disposed proximate the corner of the tray; and

the corner cavity having a protective rib projecting outwardly at an angle relative to the longitudinal axis toward the corner, the protective rib extending from the bottom to the upper end and having a trapezoidal shape disposed on the cylindrical wall portion.

2. The container of claim 1 , wherein the protective rib has a uniform depth and a uniform cross-sectional radius along at least the frustoconical wall portion.

3. The container of claim 1 , wherein each cavity has a plurality of inwardly projecting lugs to support an article within the cavity.

4. The container of claim 3 , wherein the plurality of lugs are disposed proximate the frustoconical wall portion, each lug having a width increasing toward the cylindrical wall portion.

5. The container of claim 3 , wherein the protective rib is disposed between a pair of the plurality of lugs.

6. The container of claim 1 , wherein each cavity has a further cylindrical wall portion extending upwardly from the bottom.

7. The container of claim 1 , the tray further comprising a fastener to receive a cover, the fastener disposed proximate the protective rib.

8. The container of claim 1 , further comprising a cover and a hinge extending from a side of the upper wall member, the hinge joining the tray and the cover, the corner cavity disposed proximate the corner of the upper wall opposite the hinge.

9. The container of claim 8 , further comprising an opposing corner cavity disposed proximate an opposing corner of the upper wall opposite the hinge, the opposing corner cavity having a further protective rib.

10. The container of claim 1 , wherein the tray is formed of a sheet of polymeric material.

11. A container comprising a tray, the tray comprising:

an upper wall member defining a longitudinal axis and having a longitudinal edge parallel to the longitudinal axis and an end edge transverse to the longitudinal edge, the longitudinal edge and the end edge defining a corner of the tray;

a plurality of item-receiving cavities, each cavity having a bottom, an upper end, and a frustoconical wall portion therebetween, the plurality of cavities including a corner cavity disposed proximate the corner of the tray; and

the corner cavity having a protective rib projecting outwardly at an angle relative to the longitudinal axis toward the corner, the protective an outer edge of the bottom to a corner edge of the upper end and having a uniform depth and a uniform cross-sectional radius along at least the frustoconical wall portion.

12. The container of claim 11 , wherein each cavity has a cylindrical wall portion proximate the upper end.

13. The container of claim 11 , wherein each cavity has a plurality of inwardly projecting lugs to support an article within the cavity.

14. The container of claim 13 , wherein the plurality of lugs are disposed proximate the frustoconical wall portion, each lug having a width increasing toward the cylindrical wall portion.

15. The container of claim 13 , wherein the protective rib is disposed between a pair of the plurality of lugs.

16. The container of claim 11 , wherein each cavity has a cylindrical wall portion extending upwardly from the bottom.

17. The container of claim 11 , the tray further comprising a fastener to receive a cover, the fastener disposed proximate the protective rib.

18. The container of claim 11 , further comprising a cover and a hinge extending from a side of the upper wall member, the hinge joining the tray and the cover, the corner cavity disposed proximate the corner of the upper wall opposite the hinge.

19. The container of claim 18 , further comprising an opposing corner cavity disposed proximate an opposing corner of the upper wall opposite the hinge, the opposing corner cavity having a further protective rib.

20. The container of claim 11 , wherein the tray is formed of a sheet of polymeric material.
