Abstract

A display box comprises a base tray 3 and lid 4, the lid 4 being connected to the base tray 3 by a hinge element 5 formed integrally with the lid 4. The hinge element 5 includes a formed flexible hinge portion 11 having inner and outer webs 16,17 extending between the lid 4 and base tray 3 across an offset 23 between their rear walls 15,20. It also includes a rigid hinge portion 12 that lies adjacent to the inner face of the base tray'"'"'s rear wall 20, and is attached to a tray insert 6 via a tab 13. The arrangement is such that, at closure, the lid 4 sits flush on the base tray 3, and such that the lid 4 can remain in an open position inclined to the vertical, with the flexible hinge portion 11 taut and the lower end of the lid rear wall 15 abutting the outer face of the base tray rear wall 20. This allows an item to be displayed in the box in an attractive and pleasing manner.

Claims

1. A display box including:

a base tray having a rear wall, a lid having a rear wall, and a hinge element for connecting the lid with the base tray;

wherein the hinge element extends along at least a part of an inner lower edge of the lid rear wall, and includes a flexible portion that is attached to the lid and a rigid portion that is mounted within the base tray and lies adjacent the rear wall of the base tray;

the arrangement being such that when the lid is hinged open, the flexible hinge portion extends over an upper end of the base tray rear wall, and, on becoming taut, limits the degree of opening of the lid and holds the lid in place, at an angle to the vertical.

2. The display box of claim 1, wherein the rigid hinge portion is mounted within the base tray such that it may move vertically parallel to the base tray'"'"'s rear wall.

3. The display box of claim 1, wherein the box includes an insert for holding an item to be packaged.

4. The display box of claim 3, wherein the rigid hinge element is attached to the insert.

8. The display box of claim 1, wherein when the box is closed, the base tray rear wall and lid rear wall are vertically offset from one another.

9. The display box of claim 1, wherein the base tray and lid are made from card blanks.

10. The display box of claim 1, wherein the flexible hinge portion is formed along its length, such that when the box is closed, the lid is able to lie on the base tray with the rear walls of the lid and base tray lying flush with one another.

11. The display box of claim 1, wherein the lid and hinge element are formed integrally with one another.

12. The display box of claim 11, wherein the lid and hinge element are formed integrally with one another from a blank, the rigid hinge portion being connected to the lid by a liner sheet and the flexible hinge portion being formed from a portion of the liner sheet extending between the lid and the rigid hinge portion.

13. The display box of claim 12, wherein the lid and hinge element are covered with a wrap, the flexible hinge portion being formed from a portion of the liner sheet and a portion of the wrap.

5. The display box of claim 5, wherein the insert is a tray insert.

6. The display box of claim 5, wherein the rigid hinge portion has a lower end along at least a portion of which is provided a tab portion, the tab portion being attached to the tray insert.

7. The display box of claim 6, wherein the tab portion is connected to a base portion of the tray insert.

14. A display box including a base tray, an insert within the base tray for holding an item for display, a lid, and a hinge element integrally formed with the lid for mounting the lid to the base tray, wherein:

the base tray includes a rear wall having an upper end;

the lid includes a rear wall having a lower inner edge from which the hinge element extends; and

the hinge element includes a flexible portion that extends from the lower inner edge of the lid rear wall to a rigid portion lying within the base tray adjacent the base tray'"'"'s rear wall, the rigid portion being attached to the insert;

the arrangement being such that when the lid is hinged open, the flexible hinge portion extends over the upper end of the base tray rear wall, and, on becoming taut, pulls against the insert via the rigid hinge portion to limit the degree of opening of the lid and hold the lid in place, at an angle to the vertical.

15. A method of making a display box, the method including the steps of:

forming a base tray from a blank, the base tray having a rear wall;

forming a lid from a blank, the lid having a rear wall and a hinge element; and

connecting the lid to the base tray through the hinge element;

wherein the hinge element includes a flexible portion that extends from an inner lower edge of the lid rear wall, and a rigid portion that is mounted within the base tray and lies adjacent the rear wall of the base tray;

the arrangement being such that when the lid is hinged open, the flexible hinge portion extends over an upper end of the base tray rear wall, and, on becoming taut, limits the degree of opening of the lid and holds the lid in place, at an angle to the vertical.

16. A method of making a display box, the method including the steps of:

forming a base tray from a blank;

forming a lid and hinge element from a blank, including the steps of forming a slot in a blank sheet, providing a liner sheet at least across the slot on the side of the sheet that will be the inside of the box, and cutting a blank from the blank sheet such that the perimeter of the cut intersects the slot towards the ends of the slot so as to define a lid wall flap and a rigid hinge element that are connected together by a flexible hinge element formed from the paper liner that extended across the slot;

and mounting the rigid hinge portion inside the base tray adjacent a rear wall of the base tray;

the arrangement being such that when the lid is hinged open, the flexible hinge portion extends over an upper end of the base tray rear wall, and, on becoming taut, limits the degree of opening of the lid and holds the lid in place, at an angle to the vertical.

17. The method of claim 16, including the step of forming an insert for the base tray, and attaching the rigid hinge portion to the insert.

18. The method of claim 17, wherein a wrap is provided about the lid and hinge element, and wherein a portion of the wrap is formed to extend from an edge of the rigid hinge portion to form a tab portion, and wherein the tab portion is attached to the insert.

19. The method of claim 16, wherein the flexible hinge portion is formed along its length, such that when the lid is placed on the base tray, the lid and base tray rear walls lie flush with one another.

20. A display box including:

a base tray having a rear wall;

a lid including a rear wall; and

a hinge element having a flexible hinge portion that extends from a lower inner edge of the lid rear wall to an inwardly facing surface of a rigid hinge portion, the rigid hinge portion lying within the base tray adjacent the base tray'"'"'s rear wall and the flexible hinge portion being shaped along its length such that it forms a dog leg across its width,

the arrangement being such that when the display box is closed the lid and base tray lie flush with respect to one another, and such that when the lid is hinged open, the flexible hinge portion extends over an upper end of the base tray rear wall, and, on becoming taut, limits the degree of opening of the lid and holds the lid in place at an angle to the vertical.

21. A method of making a display box, the method Including the steps of:

forming a base tray from a blank, the base tray having a rear wall;

forming an integral lid and hinge element, the lid having a rear wall and the hinge element having a flexible portion that extends from an inner lower edge of the lid rear wall and a rigid portion that extends from the flexible portion;

shaping the flexible portion so as to take up a dog leg across its width; and

connecting the lid to the base tray through the hinge element such that the rigid portion is mounted within the base tray and lies adjacent the rear wall of the base tray;

the arrangement being such that when the display box is dosed the lid and base tray lie flush with respect to one another, and such that when the lid is hinged open, the flexible hinge portion extends over an upper end of the base tray rear wall, and, on becoming taut, limits the degree of opening of the lid and holds the lid in place, at an angle to the vertical.
