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. Methods of assembling and operation are described.

1. A method of using a resealable package, said method comprising steps of: (a) providing a package having a surrounding wall; a resealable mouth; and a resealable closure mechanism with a slider device thereover for opening and resealing the mouth said closure mechanism comprising a locking finger and at least one closure member; the slider device comprising: (i) a top wall; the top wall having first and second opposite ends; (ii) a first sidewall and a second sidewall depending from and integral with the top wall, the first sidewall extending a first distance from the top wall; together, the top wall, first sidewall and second sidewall defining a cavity, the slider device comprising only one cavity; and (iii) an engagement structure depending from and integral with the top wall positioned within the only on cavity; the engagement structure positioned between the first sidewall and the second sidewall, extending a second distance from the top wall, wherein the second distance is less than the first distance, and the engagement structure having a first profile at the first end and a second profile at the second end, the first profile being different from the second profile; and (b) moving the slider device along the rosealable closure mechanism in a first direction to engage the engagement structure at the first end of the slider device with said locking finger of the resealable closure mechanism which engages said at least one closure member without said engagement structure engaging said at least one closure member to close the resealable closure mechanism. 2. The method according to claim 1, wherein: (a) said step of providing a package includes providing a slider device wherein the engagement structure at the first end includes a first protrusion; and (b) said step of moving the slider device in a first direction includes engaging the first protrusion with a locking member on the resealable closure mechanism to urge a lower latching portion of a first closure member to interlock with a second closure member. 3. The method according to claim 1, said method further comprising the step of: (a) moving the slider device along the resealable closure mechanism in a second direction to engage the engagement structure at the second end to open the resealable closure mechanism. 4. The method according to claim 3, wherein: (a) said step of providing a package includes providing a slider device wherein the engagement structure at the second end includes a second protrusion; and (b) said step of moving the slider device in a second direction includes engaging the second protrusion with a locking member on the resealable closure mechanism to disengage a lower latching portion of a first closure member from a second closure member. 5. The method according to claim 1, wherein the step of providing a package includes providing a slider device wherein: (a) the second sidewall extends a third distance from the top wall; and 6. The method according to claim 5, wherein the step of providing a package includes providing a slider device wherein: (a) the first distance is the same as the third distance. 7. The method according to claim 2, wherein the step of providing a package includes providing a slider device wherein: (a) the first protrusion is located about 45 to 55% of a distance between the first sidewall and the second sidewall. 8. The method according to claim 4, wherein the step of providing a package includes providing a slider device wherein: (a) the second protrusion has a width; and (b) the second protrusion is located no more than its width from one of the first sidewall and the second sidewall. 9. The method according to claim 8, wherein the step of providing a package includes providing a slider device wherein: (a) the second protrusion is located about 0.1 to 5 mm from one of the first sidewall and the second sidewall.
