Claims20
A lens box blank for folding into a lens box comprises:
- a base segment;
- a stem segment extending from a bottom side of the base segment, the stem segment comprising a first securing flap, a top panel, and a front panel;
- a first cross-bar segment extending from a first side of the base segment, the first cross-bar segment comprising a first lens securing panel, a first lens support frame panel, a first support frame top panel, and a first side panel, wherein an intersection of the first support frame top panel and the first side panel comprises first side panel tabs;
- and
- a second cross-bar segment extending from a second side of the base segment, the second cross-bar segment comprising a second lens securing panel, a second lens support frame panel, a second support frame top panel, and a second side panel, wherein an intersection of the second support frame top panel and the second side panel comprises second side panel tabs;
- and,
- wherein the base segment, the stem segment, the first cross-bar segment, and the second cross-bar segment are configured to be folded to form a lens box.
A lens box for storing ophthalmic lenses, comprising:
- a base panel;
- a top panel;
- a pair of side panels extending between the base panel and the top panel, the pair of side panels including a first side panel comprising first side panel tabs and a second side panel comprising second side panel tabs;
- a front panel extending between the base panel and the top panel;
- a first lens holder for holding a first lens, the first lens holder extending from the first side panel to form a first cavity for receiving the first lens;
- and
- a second lens holder for holding a second lens, the second lens holder extending from the second side panel to form a second cavity for receiving the second lens;
- wherein the first side panel tabs and the second side panel tabs are configured to push the first lens holder and the second lens holder further interior for a secure fit of the first lens and the second lens.
A method of storing lenses in a lens box, the lens box comprising a first lens holder having a first lens support opening and first side panel tabs extending outward and a second lens holder having a second lens support opening and second side panel tabs extending outward, comprising the steps of:
- inserting a first lens in the first lens support opening of the first lens holder of the lens box such that a first outer edge of the first lens engages with a first inner edge of the first lens support opening;
- inserting a second lens in the second lens support opening of the second lens holder of the lens box such that a second outer edge of the second lens engages with a second inner edge of the second lens support opening;
- and
- securing the first and second lenses in the first and second lens holders by pushing the first and second side panel tabs inward such that the first and second lens holders are being pushed further interior for a tighter fit of the first and second lenses.
