Abstract

A two piece thermoformed container comprising a tray and a lid for holding large and small objects is provided. The container is portable, recloseable and provides easy access to the contents. The tray includes a front wall, rear wall and opposing side walls. Each side wall defines an elongated rib. The lid comprises a rear covering portion, a recessed front covering portion and side walls. The lid side walls form grooves which receive the tray ribs. The lid is moveable in a sliding fashion between a fully closed position in which the lid front portion abuts the tray front wall and a fully opened position in which lid backstops abut the tray rear wall. The lid and tray may remain engaged at all times.

First claim

The invention claimed is:

1. A recloseable container comprising:
a thermoformed tray comprising a bottom wall, side walls, a front wall and a rear wall, the bottom wall having a periphery, the side walls, front wall and rear wall each extending upward from the periphery and terminating in a rim that defines an opening, the tray further comprising a flange extending outwardly from the rim, the tray including an elongated rib extending inwardly from each side wall; and
a thermoformed lid comprising a cover portion that covers the opening and a lid flange that extends outward from a periphery of the cover portion and has a rear edge, the cover portion comprising a rear cover portion defining a plane and a front cover portion, the front cover portion comprising a recessed back wall extending downward from the rear cover portion, a recessed front wall and recessed side walls extending downward from the top wall periphery, and a recessed cover portion extending between the recessed front wall, recessed back wall and recessed side walls, each recessed side wall defining a groove configured to receive one of the elongated ribs in the tray to secure the lid to the tray in sliding fashion; wherein
the lid is moveable in a sliding fashion between a fully closed position in which the recessed front wall of the lid abuts the tray front wall, and a fully opened position in which the recessed back wall abuts the tray rear wall.

2. The recloseable container of claim 1 wherein:
the lid is engaged to the tray in both the fully closed and fully opened positions.

3. The recloseable container of claim 1 wherein:
when the lid is in the fully opened position the tray ribs at least partially engage the grooves on either side of the lid.

4. The recloseable container of claim 1 wherein:
the distance between the forward end of each groove and the recessed back wall exceeds the distance between the rear end of each rib and the tray rear wall.

5. The recloseable container of claim 1 wherein:
as the lid moves with respect to the tray, the lid flange slides across and remains in contact with the tray flange.

6. The recloseable container of claim 1 wherein:
the lid further comprises one or more backstops integrally formed in the recessed back wall.

7. The recloseable container of claim 1 wherein:
each sidewall comprises a lower section extending upward from the bottom wall periphery to an inner edge, a ledge extending outward from the inner edge and terminating in an outer edge, and an upper section extending upward from the outer edge and terminating at the rim; and
the elongated rib extends inwardly from the upper section.

8. The recloseable container of claim 7 wherein:
the tray further comprises one or more dimple stops extending upward from the ledge near the front wall; and
the recessed cover portion includes one or more dimples configured to receive and mate with the one or more dimple stops to lock the lid in the closed position before and after each use.

9. The recloseable container of claim 1 wherein:
the recessed cover portion comprises an upwardly extending ridge that defines a thumb depression.

10. The recloseable container of claim 1 wherein:
the tray further comprises a tray tab extending rearward from the tray flange; and
the lid further comprises a lid tab extending rearward from the rear edge of the lid;
the tray tab and lid tab having complementary shapes so they fit together in close engagement.

11. The recloseable container of claim 10 wherein:
the tray tab is attached to the tray along a hinge line; and
the lid tab is attached to the lid along a hinge line.

12. The recloseable container of claim 11 wherein:
the tray hinge line and the lid hinge line are each perforated to allow the tray tab and the lid tab to break off before use.

13. The recloseable container of claim 1 wherein:
the rear cover portion includes a downward extending ridge located near and parallel to the lid rear edge, the ridge configured to abut the rear wall of the tray when the container is in the closed position.

14. The recloseable container of claim 13 wherein:
the ridge rides over the tray rear wall as the lid is moved from the fully closed position to the fully open position.

15. A recloseable container comprising:
a thermoformed tray comprising a bottom wall, side walls, a front wall and a rear wall, the bottom wall having a periphery, the side walls, front wall and rear wall each extending upward from the periphery and terminating in a rim that defines an opening, the tray further comprising a flange extending outwardly from the rim, each sidewall comprising a lower section extending upward from the bottom wall periphery to an inner edge, a ledge extending outward from the inner edge and terminating in an outer edge, and an upper section extending upward from the outer edge and terminating at the rim, the upper section including an elongated rib extending inwardly from each side wall above and substantially parallel to the ledge, the tray further comprising one or more dimple stops extending upward from the ledge near the front wall; and
a thermoformed lid comprising a cover portion that covers the opening and a lid flange that extends outward from a periphery of the cover portion and is in sliding contact with the tray flange, the cover portion comprising a rear cover portion defining a plane and a front cover portion, the front cover portion comprising a recessed back wall extending downward from the rear cover portion, a recessed front wall and recessed side walls extending downward from the top wall periphery, and a recessed cover portion extending between the recessed front wall, recessed back wall and recessed side walls, the recessed cover portion including one or more dimples configured to receive and mate with the one or more dimple stops to lock the lid in the closed position before and after each use, each recessed side wall defining a groove configured to receive one of the elongated ribs in the tray to secure the lid to the tray in sliding fashion, the lid further comprising one or more backstops integrally formed in the recessed back wall; wherein
the lid is moveable in a sliding fashion between a fully closed position in which the recessed front wall of the lid abuts the tray front wall, and a fully opened position in which the one or more backstops abut the tray rear wall; and
the lid is engaged to the tray in both the fully closed and fully opened positions.

16. The recloseable container of claim 15 wherein:
the recessed cover portion comprises an upwardly extending ridge that defines a thumb depression.

17. The recloseable container of claim 16 wherein:
the tray further comprises a tray tab extending rearward from the tray flange; and
the lid further comprises a lid tab extending rearward from the rear edge of the lid;
the tray tab and lid tab having complementary shapes so they fit together in close engagement.

18. The recloseable container of claim 17 wherein:
the tray tab is attached to the tray along a hinge line; and
the lid tab is attached to the lid along a hinge line.

19. The recloseable container of claim 18 wherein:
the rear cover portion includes a downward extending ridge located near and parallel to the lid rear edge, the ridge configured to abut the rear wall of the tray when the container is in the closed position.

20. A recloseable container comprising:
a thermoformed tray comprising a bottom wall, side walls, a front wall and a rear wall, the bo
