## Abstract

The present disclosure relates to a plastic or polymeric container (100) with reclosable zippers or reclosures (10) which make the package child-resistant. In one typical embodiment, this is achieved by a zipper or reclosure (10) including a first profile (12) with a first lower interlocking element (28) and a first upper interlocking element (29), wherein the first profile (12) is severed through the first upper interlocking element (29) to form a lower first profile (12′) and an upper first profile (12″). This severing forms at least one tab (18) extending from an upper edge of the lower first profile (12′) and including a portion of the first upper interlocking element (29′). The second profile (14) includes a second web portion (30) with a second lower interlocking element (44) and a second upper interlocking element (46).

## Claims

### Claim 1

A reclosure (10) for a reclosable package (100), including:
a first profile (12) and a second profile (14);
the first profile (12) including a first web portion (16) with a first lower interlocking element (28) and a first upper interlocking element (29), wherein first profile (12) is severed through the first upper interlocking element (29) to form a lower first profile (12′) and an upper first profile (12″) thereby forming at least one tab (18) extending from an upper edge of the lower first profile (12′) and including a portion of the first upper interlocking element (29′); and
the second profile (14) including a second web portion (30) with a second lower interlocking element (44) and a second upper interlocking element (46).

### Claim 2 (depends on 1)

The reclosure (10) of claim 1 wherein the lower first profile (12′) includes a first lower sealing flange (20) and the upper first profile (12″) includes a first upper sealing flange (21).

### Claim 3 (depends on 1)

The reclosure (10) of claim 1 wherein the second profile (14) includes a second lower sealing flange (32) and a second upper sealing flange (34).

### Claim 4 (depends on 1)

The reclosure (10) of claim 1 wherein the lower first profile (12′) and the upper first profile (12″) are separated by severing the first profile (12).

### Claim 5 (depends on 1)

The reclosure (10) of claim 1 wherein the at least one tab (18) includes a plurality of tabs (18).

### Claim 6 (depends on 5)

The reclosure (10) of claim 5 wherein the plurality of tabs (18) are spaced periodically along the upper edge of the lower first profile (12′).

### Claim 7 (depends on 6)

The reclosure (10) of claim 6 wherein, in an interlocked configuration, the plurality of tabs (18) are interlocked with the second upper interlocking elements (46).

### Claim 8 (depends on 7)

The reclosure (10) of claim 7 wherein the plurality of tabs (18) are pealed from the second upper interlocking elements (46) to open the reclosure (10).

### Claim 9 (depends on 1)

The reclosure (10) of claim 1 wherein, in an interlocked configuration, the first and second upper interlocking elements (29, 46) are interlocked with each other and the first and second lower interlocking elements (28, 44) are interlocked with each other.

### Claim 10 (depends on 1)

The reclosure (10) of claim 1 wherein the first lower and upper interlocking elements (28, 29) and the second lower and upper interlocking elements (44, 46) extend longitudinally along the reclosure (10) in parallel.

### Claim 11 (depends on 1)

The reclosure (10) of claim 1 wherein interior surfaces of a first lower sealing flange (20), a first upper sealing flange (21), a second lower sealing flange (32) and a second upper sealing flange (34) include anti-sealing protrusions (26, 27, 40, 42).

### Claim 12 (depends on 11)

The reclosure (10) of claim 11 wherein the anti-sealing protrusions (26, 27, 40, 42) extend longitudinally along the reclosure (10).

### Claim 13 (depends on 1)
