Microstructure connecting mechanism and plastic storage bag with microstructure closure mechanism

A storage bag comprising:

• a first side surface;
• a second side surface connected to the first side surface, the connected first and second side surfaces forming an interior of the bag with an opening to the interior;
• and
• a first closure strip that is substantially planar and is provided on the first side surface adjacent to the opening of the bag, the first closure strip including a plurality of protrusions extending from a surface of the first strip, the protrusions extending a distance of less than about 500 μm from the surface of the first strip, and the plurality of protrusions defining a plurality of grooves between adjacent protrusions, with a pressure sensitive adhesive provided in at least some of the grooves defined between adjacent protrusions extending from the first strip;
• and
• a second closure strip that is substantially planar and is provided on the second side surface adjacent to the opening of the bag, the second closure strip including a plurality of protrusions extending from a surface of the second strip, the protrusions extending a distance of less than about 500 μm from the surface of the second strip, and the plurality of protrusions defining a plurality of grooves between adjacent protrusions,
• wherein, when the first and second closure strips are connected, the plurality of protrusions extending from the surface of the first strip is configured to be received in the grooves defined by the plurality of protrusions extending from the surface of the second strip, and the plurality of protrusions extending from the surface of the second strip is configured to be received in the grooves defined by the plurality of protrusions extending from the surface of the first strip, with the plurality of protrusions extending from the surface of the second strip contacting the pressure sensitive adhesive to thereby seal the opening of the bag.

A connecting mechanism comprising:

• a first strip that is substantially planar;
• a plurality of protrusions extending from a surface of the first strip, the protrusions extending a distance of less than about 500 μm from the surface of the first strip, and the plurality of protrusions defining a plurality of grooves between adjacent protrusions;
• a pressure sensitive adhesive provided in grooves that are defined by the protrusions extending from the first strip, the pressure sensitive adhesive being provided from a position adjacent to one end of the first strip to a position adjacent to a second end of the first strip;
• a second strip that is substantially planar;
• and
• a plurality of protrusions extending from a surface of the second strip, the protrusions extending a distance of less than about 500 μm from the surface of the second strip, and the plurality of protrusions defining a plurality of grooves between adjacent protrusions,
• wherein the plurality of protrusions extending from the first strip are configured to be received in the grooves defined by the plurality of protrusions extending from the second strip, and
• wherein, when the first and second strips are connected together, the plurality of protrusions extending from the surface of the second strip is received in the grooves defined by the plurality of protrusions extending from the surface of the first strip, with the plurality of protrusions extending from the surface of the second strip contacting the pressure sensitive adhesive.
