Bistable pull-snap hold open mechanism and method

A method of using a tape feed hold open mechanism comprising:

• providing a tape feed hold open mechanism comprising a flexible first flat strip comprised of a polyolefin material having:
• a first end;
• a second end opposite the first end;
• an inner mating surface;
• an outer bonding surface opposite the inner mating surface;
• a flexible second flat strip positioned relative to the first flat strip, the second flat strip comprised of a polyolefin having:
• a first end;
• a second end opposite the first end;
• an inner mating surface;
• an outer bonding surface opposite the inner mating surface;
• one or more pivot members and one or more flexures integrated into the second flat strip separating the second flat strip into a side seal portion and an operable portion, the side seal portion coupled to the operable portion,
• mounting the tape feed hold open mechanism proximate the opening of a package on the inside walls of the package,
• applying a separating pressure between the first flat strip and second flat strip;
• sliding the one or more flexures from a first flat configuration to a second bent configuration, holding the first flat strip separate from the second flat strip allowing easy access to the contents of the package;
• applying a compressive pressure between the first flat strip and second flat strip;
• and
• sliding the one or more flexures from a second bent configuration to a first flat configuration thus closing and mating the first flat strip relative to the second flat strip.

A fitment bistable hold open mechanism, comprising:

• a flexible first flat strip comprised of a polyolefin material having:
• an inner mating surface;
• an outer bonding surface opposite the inner mating surface;
• a flexible second flat strip positioned relative to the first flat strip, the second flat stripe comprised of a polyolefin having:
• an inner mating surface;
• an outer bonding surface opposite the inner mating surface;
• one or more pivot members pivotally coupling the first flat strip to the second flat strip;
• and
• one or more primary flexures proximate the one or more pivot members, and
• wherein the fitment bistable hold open mechanism is applied proximate the opening of a package on the inside walls of the package.

• mounting the fitment bistable hold open mechanism proximate the opening of a package on the inside walls of the package,
• applying a separating pressure between the first flat strip and second flat strip;
• sliding the one or more flexures from a first closed and disengaged configuration to a second open and engaged configuration, holding the first flat strip separate from the second flat strip allowing easy access to the contents of the package;
• applying a compressive pressure between the first and second flat strip;
• and sliding the one or more flexures from a second open and disengaged configuration to a first closed and disengaged configuration thus closing and mating the first flat strip relative to the second flat strip.
