Resealable closure mechanism having a slider device and methods
View Patent ↗A slider device having contoured top and sidewalls is disclosed for use with a resealable package. In a first embodiment, the slider device includes an engagement structure for engaging and interlocking first and second closure profiles of a resealable closure mechanism. The engagement structure includes a first protrusion and a second protrusion depending from the top wall of the slider device for engaging first and second closure profiles of a resealable closure mechanism. The first and second protrusions selectively open and close the resealable closure mechanism as the slider device is moved from a first position to a second position. In a second embodiment, a slider device is disclosed having first and second slide channels that engage first and second closure profiles. The first and second slide channels selectively open and close the resealable closure mechanism as the slider device is moved from a first position to a second position.

(iii) said first and second closure profiles being constructed and arranged to interlock; and
(c) a slider device operably mounted on said resealable closure mechanism for selectively closing and opening said resealable closure mechanism by moving said slider device to said resealable closure mechanism in opposite first and second directions; said slider device including;
(i) a top wall; said top wall having first and second opposite ends; and
(ii) an engagement structure depending from and integral with said top wall; said engagement structure being constructed and arranged to engage said locking finger such that said lower latching portion of said first catch interlocks with said second catch of said second closure member when said slider device is selectively moved along said resealable closure mechanism in said first direction; and
(iii) said locking finger is constructed and arranged to engage and interlock with said upper latching portion of said first catch when said engagement structure engages said locking finger.
2. The flexible package according to claim 1 , wherein:
(a) said engagement structure is constructed and arranged to engage said locking finger such that said lower latching portion of said first closure member disengages from said second catch of said second closure member when said slider device is selectively moved along said resealable closure mechanism in said second direction.
3. The flexible package according to claim 1 , wherein said engagement structure includes:
(a) a first protrusion depending from and integral with said first end of said top wall; said first protrusion depending from said top wall substantially near the center of said top wall; said first protrusion being constructed and arranged for engaging and interlocking said closure members when said slider device is operably mounted on said resealable package and moved in said first direction; and
(b) a second protrusion depending from and being integral with said second end of said top wall; said second protrusion being constructed and arranged to engage said locking finger such that said lower latching portion of said first closure member disengages from said second catch of said second closure member when said slider device is selectively moved along said resealable closure mechanism in said second direction.
4. The flexible package according to claim 3 , wherein:
(a) said locking finger has a distal end and a proximal end; said proximal end being attached to said first upper flange;
(b) said second protrusion being constructed and arranged to engage said locking finger substantially near the proximal end of the locking finger.
5. The flexible package according to claim 3 , wherein:
(a) said locking finger is constructed and arranged to engage and interlock with said upper latching portion of said first catch when said first protrusion engages said locking finger.
6. A reclosable closure mechanism, comprising:
(a) a first closure profile; said first closure profile having a first upper flange; a first closure member having a first catch; a locking finger extending from said first upper flange;
(i) said locking finger being constructed and arranged for engaging and interlocking with said first catch;
(ii) said first catch having an upper latching portion and a lower latching portion;
(b) a second closure profile; said second closure profile having a second catch;
i. said first and second closure profiles being constructed and arranged to interlock; and
(c) a slider device operably mounted on said first and second closure profiles for selectively closing and opening said resealable closure mechanism by moving said slider device relative to said resealable closure mechanism in opposite first and second directions; said slider device including:
(i) a top wall; said top wall having first and second opposite ends;
(ii) an engagement structure depending from and integral with said top wall; said engagement structure being constructed and arranged to engage said locking finger such that said lower latching portion of said first catch interlocks with said second catch of said second closure member when said slider device is selectively moved along said resealable closure mechanism in said first direction; and
(iii) said locking finger being constructed and arranged for engaging and interlocking with said upper latching portion of said first catch when said engagement structure engages said locking finger.
7. The reclosable closure mechanism according to claim 6 , wherein:
(a) said engagement structure is constructed and arranged to engage said locking finger such that said lower latching portion of said first closure member disengages from said second catch of said second closure member when said slider device is selectively moved along said resealable closure mechanism in said second direction.
8. The reclosable closure mechanism according to claim 6 , wherein said engagement structure includes:
(a) a first protrusion depending from and integral with said first end of said top wall; said first protrusion depending from said top wall substantially near the center of said top wall; said first protrusion being constructed and arranged for engaging and interlocking said closure members when said slider device is operably mounted on said resealable package and moved in said first direction; and
(b) a second protrusion depending from and being integral with said second end of said top wall; said second protrusion being constructed and arranged to engage said locking finger such that said lower latching portion of said first closure member disengages from said second catch of said second closure member when said slider device is selectively moved along said resealable closure mechanism in said second direction.
9. The reclosable closure mechanism according to claim 8 , wherein:
