Abstract

A packaged oral care implement ( 1000 ) and method of opening the same. In one embodiment, the package ( 2000 ) includes a tab ( 106 ) on a first panel ( 100 ) of the package that is strategically located so that the oral care implement itself ( 1000 ) acts as a foundation or barrier adjacent to the tab that assists with shearing the first panel to release the tab.

First claim

What is claimed is:

1. A packaged oral care implement comprising:
a first panel and a second panel, a cavity formed between the first and second panels;
the first panel comprising at least one pre-weakened line that defines a tear-away portion and a base portion, the base portion coupled to the second panel;
the base portion comprising a tab that protrudes into the tear-away portion, an edge of the tab defined by a first portion of the pre-weakened line;
an oral care implement positioned within the cavity so that a portion of the oral care implement lies beneath a first portion of the tear-away portion adjacent the tab, the tab located above an unoccupied portion of the cavity; and
the tab alterable, in response to a downward force applied to the tab, from: (1) a closed state in which the first portion of the pre-weakened line is intact; and (2) an open state in which the first portion of the pre-weakened line is sheared, the tab is deflected into the unoccupied portion to a depth below an upper surface of the portion of the oral care implement, and an opening is defined in the first panel for grasping the tear-away portion and at least partially separating the tear-away portion from the base portion to provide access to the oral care implement.

2. The packaged oral care implement according to claim 1 wherein upon the downward force being applied to the tab, the first portion of the tear-away portion contacts the portion of the oral care implement, thereby causing the first portion of the pre-weakened line to shear to release the tab.

3. The packaged oral care implement according to claim 1 wherein the cavity extends along a longitudinal axis, and wherein the tab deflects about a flexure axis that extends substantially parallel to the longitudinal axis.

4. The packaged oral care implement according to claim 1 wherein the cavity extends along a longitudinal axis, and wherein the tab deflects about a flexure axis that extends oblique to the longitudinal axis.

5. The packaged oral care implement according to claim 1 wherein a distal portion of the edge travelling along a path when the tab is moved from the closed state to the open state, wherein the path does not intersect the oral care implement.

6. The packaged oral care implement according to claim 5 wherein the edge of the tab comprises first and second inside corners at a base of the tab and only one outside corner along the distal portion of the edge.

7. The packaged oral care implement according to claim 5 wherein the edge of the tab comprises first and second inside corners at a base of the tab and at least two outside corners along the distal portion of the edge.

8. The packaged oral care implement according to claim 1 wherein the pre-weakened line comprises a second portion, and wherein the first portion of the pre-weakened line has a first pre-weakening pattern having a first non-zero shear strength and the second portion of the pre-weakened line has a second pre-weakening pattern having a second non-zero shear strength that is greater than the first non-zero shear strength.

9. The packaged oral care implement according to claim 8 wherein the first portion is disposed between two sections of the second portion.

10. The packaged oral care implement according to claim 1 further comprising a retaining element that maintains the oral care implement in a substantially fixed position in the cavity.

11. The packaged oral care implement according to claim 10 further comprising a third panel, the third panel comprising the retaining element and positioned between the first and second panels to form a floor of the cavity.

12. The packaged oral care implement according to claim 11 further comprising a fourth panel positioned between the third and second panels, the fourth panel comprising product indicia.

13. The packaged oral care implement according to claim 1 wherein the first panel is substantially planar when the downward force is not applied.

14. The packaged oral care implement according to claim 13 wherein no portion of the oral care implement is located beneath the tab, as measured in a direction substantially perpendicular to a plane in which the first panel is located.

15. The packaged oral care implement according to claim 1 wherein a lower surface of the first panel that forms an upper bound of the cavity is free of any protuberances.

16. The packaged oral care implement according to claim 1 wherein the first panel is formed of a clarified PVC and the second panel is formed of an opaque PVC.

17. The packaged oral care implement according to claim 1 wherein the base portion forms a perimeter portion of the first panel that surrounds the tear-away portion.

18. A packaged oral care implement comprising:
a first panel and a second panel, a cavity formed between the first and second panels;
the first panel comprising at least one pre-weakened line that defines a tear-away portion and a base portion, the base portion coupled to the second panel;
the base portion comprising a tab that protrudes into the tear-away portion, an edge of the tab defined by a first portion of the pre-weakened line; and
an oral care implement positioned within the cavity so that a portion of the oral care implement lies beneath a first portion of the tear-away portion adjacent the tab, the tab located above an unoccupied portion of the cavity,
wherein upon a downward force being applied to the tab, the first portion of the tear-away portion contacts the portion of the oral care implement, thereby causing the first portion of the pre-weakened line to shear and release the tab to allow the tab to deflect into the unoccupied portion to a depth below an upper surface of the portion of the oral care implement, such that an opening is defined in the first panel for grasping the tear-away portion and at least partially separating the tear-away portion from the base portion.

19. The packaged oral care implement according to claim 18 wherein the cavity extends along a longitudinal axis, and wherein the tab deflects about a flexure axis that extends substantially parallel to the longitudinal axis.

20. The packaged oral care implement according to claim 18 wherein the cavity extends along a longitudinal axis, and wherein the tab deflects about a flexure axis that extends substantially perpendicular to the longitudinal axis.

21. The packaged oral care implement according to claim 18 wherein the cavity extends along a longitudinal axis, and wherein the tab deflects about a flexure axis that extends oblique to the longitudinal axis.

22. The packaged oral care implement according to claim 18 wherein the edge of the tab comprises first and second inside corners at a base of the tab and only one outside corner along a distal portion of the edge.

23. The packaged oral care implement according to claim 18 wherein the edge of the tab comprises first and second inside corners at a base of the tab and at least two outside corners along a distal portion of the edge.

24. The packaged oral care implement according to claim 18 wherein the edge of the tab comprises a distal portion, the distal portion of the tab travelling along a path when the tab is moved from the closed state to the open state, wherein the path does not intersect the oral care implement.

25. The packaged oral care implement according to claim 18 wherein the pre-weakened line comprises a second portion, and wherein the first
