Abstract

A container having a hinged opening flap having free end portion. The free end portion comes into facing relationship with a free end portion seat. One or more locking tabs connected to the opening flap or the free end portion seat edge are provided. The locking tabs can lock the opening flap into a closed position. The container can be erected from a blank.

Claims

1. A container comprising:

a top panel having a top panel exterior facing surface;

a hinge;

an opening flap connected to said hinge;

two locking tabs connected to one of said opening flap and a free end portion seat having a free end portion seat edge, wherein said free end portion seat is recessed relative to said top panel exterior facing surface; and

a container body engaged with said top panel, wherein said top panel, said opening flap, and said container body together define an interior space;

wherein said opening flap comprises;

a hinged portion having two hinged portion ends;

a free end portion in facing relationship with said free end portion seat; and

two opening flap edges separable from said top panel, each opening flap edge extending from one of said hinged portion ends to said free end portion;

wherein said free end portion overlies said free end portion seat edge between two intersection points separated by a separation distance;

wherein for each opening flap edge, said opening flap edge is in a nonoverlapping relationship with said top panel from said intersection point to along said opening flap edge to a distance of more than about 20% of said separation distance;

wherein said locking tab is closer to said hinge than said free end portion is to said hinge;

wherein said free end portion is between said locking tabs; and

wherein said locking tabs are connected with and extend away from one of said opening flap edge and said free end portion seat edge.

2. The container according to claim 1, wherein said opening flap edges are discontinuous with said top panel and said opening flap and said free end portion seat are operably engaged with one another by said locking tabs.

3. The container according to claim 2 wherein said nonoverlapping relationship is an abutting relationship.

4. The container according to claim 3, wherein said hinge connects said opening flap to said top panel or a rear panel connected to said top panel, said container body further comprising said rear panel.

5. The container according to claim 4, wherein along at least a portion of said opening flap edges from proximal said hinged portion ends towards said locking tab said opening flap overlaps said top panel.

6. The container according to claim 1, wherein said locking tabs are separated from one another by a locking tab spacing and each of said opening flap edges is in a nonoverlapping relationship with said top panel from said locking tabs to along said opening flap edge to a distance of more than about 20% of said locking tab spacing.

7. The container according to claim 6, wherein along at least a portion of said opening flap edges from proximal said hinged portion ends towards said locking tabs said opening flap overlaps said top panel.

8. The container according to claim 7, wherein said locking tabs are integral with said opening flap.

9. The container according to claim 8, wherein between each said locking tab and said free end portion is a slit.

10. The container according to claim 8, wherein said opening flap comprises one or more weakened portions having an end or ends oriented towards said locking tabs.

11. The container according to claim 1, wherein said container body comprises a front panel connected to said top panel, wherein said locking tabs are integral with and extend away from said opening flap edge towards said front panel, wherein said locking tabs have locking tab edges oriented towards said front panel, wherein said locking tab edges are nearer to said front panel than said free end portion seat edge.

12. The container according to claim 1:

wherein said locking tabs are separated from one another by a locking tab spacing;

wherein said opening flap edges are at least partially defined by reverse cuts extending from proximal said hinged portion ends towards said locking tabs; and

wherein at a distance from said locking tabs of more than about 20% of said locking tab spacing said reverse cuts merge.

13. The container according to claim 12,

wherein said top panel has a top panel interior facing surface oriented towards said interior space;

wherein said container body comprises a front panel extending from said free end portion seat and said free end portion seat is in facing relationship with and joined to said top panel interior facing surface;

wherein said container body comprises a rear panel connected to said top panel

wherein said hinge connects said opening flap to said top panel or said rear panel; and

wherein said front panel, said free end portion seat, said top panel, said opening flap, and said rear panel are a one-piece paperboard.

14. The container according to claim 13, wherein said locking tabs are integral with said opening flap.

15. The container according to claim 14, wherein between each said locking tab and said free end portion is a slit.

16. The container according to claim 14, wherein said opening flap comprises one or more lines of weakness having an end or ends oriented towards said locking tabs.

17. A container according to claim 1, wherein said locking tabs are integral with said opening flap and said locking tabs project beyond said free end portion seat edge;

wherein said nonoverlapping relationship is an abutting relationship;

wherein at least a portion of said opening flap edges and said panel are separable from one another by a reverse cut structure; and

wherein said opening flap, said panel, and said container body comprise a one-piece paperboard.

18. A container comprising:

a top panel having a top panel interior facing surface;

a free end portion seat in facing relationship with and joined to said top panel interior facing surface, wherein said free end portion seat has a free end portion seat edge;

a hinge;

an opening flap connected to said hinge;

two locking tabs integral with one of said opening flap and said free end portion seat edge; and

a container body engaged with said top panel, wherein said top panel, said opening flap, and said container body together define an interior space, wherein said container body, said free end portion seat, said locking tab, said top panel, and said opening flap are a one-piece paperboard;

wherein said opening flap comprises;

a hinged portion having two hinged portion ends;

a free end portion in facing relationship with said free end portion seat, wherein said free end portion is between said locking tabs and

wherein said free end portion overlies said free end portion seat edge between two intersection points separated by a separation distance; and

two opening flap edges at least partially defined by reverse cuts extending from proximal said hinged portion ends towards said locking tabs, wherein at a distance from said locking tabs of more than about 20% of said separation distance said reverse cuts merge;

wherein said locking tabs are closer to said hinge than said free end portion is to said hinge; and

wherein said container contains dryer sheets comprising a fabric softening active and perfume.

19. A carton blank comprising:

a free end portion seat having a free end portion seat edge;

a front panel extending from and integral with said free end portion seat across a first fold line, said free end portion seat between said first fold line and said free end portion seat edge;

a bottom panel extending from and integral with said front panel across a second fold line;

a rear panel extending from and integral with said bottom panel across a third fold line;
