Storage bag having a slider with ridges that presses together and separates interlocking profiles of fastener strips

A storage bag comprising:

• a first side surface;
• a second side surface connected to the first side surface so as to define an interior of the bag with an opening thereto;
• a first fastener strip positioned adjacent to the opening of the bag, the first fastener strip including at least one interlocking profile;
• a second fastener strip positioned adjacent to the opening of the bag, the second fastener strip including at least one interlocking profile configured to interlock with the interlocking profile of the first fastener strip;
• and
• a slider including a first sidewall, a second sidewall, and a top wall connecting the first sidewall and the second sidewall, the slider being configured (a) to press together the interlocking profiles of the first and second fastener strips as the slider moves from a first end to a second end of the bag, and (b) to separate the interlocking profiles of the first and second fastener strips as the slider moves from the second end to the first end of the bag, wherein the slider includes (i) a plurality of ridges extending from the first sidewall, the plurality of ridges extending further from the first sidewall at the ends of the slider than at a position at the center of the length of the slider, and (ii) a plurality of ridges extending from the second sidewall, the plurality of ridges extending further from the second sidewall at the ends of the slider than at a position at the center of the length of the slider,
• wherein a first end-stop is formed by the first and second fastener strips adjacent to the first end of the bag, and a second end-stop is formed by the first and second fastener strips adjacent to the second end of the bag, and
• wherein the first end-stop can be received between the first and second sidewalls of the slider to a point that is substantially at the center of the length of the slider.
