Hidden display case with offset center seam glue joint

A display case formed from a blank comprising a first panel, a second panel, a third panel and a fourth panel connected in series at respective first, second and third vertical fold lines, the second panel including a tear-away section defining a first portion of the second panel separated from a second portion of the second panel by a separation line, and the fourth panel including a main body and a secondary section connected to the main body at a fourth vertical fold line, the display case comprising:

• a front wall defined by the second portion of the second panel;
• a back wall defined by the fourth panel main body parallel to the front wall;
• a first side wall defined by the first panel and the secondary section;
• a second side wall defined by the third panel, wherein the first and second side walls connect the front and back walls;
• a first manufacturer's joint strip engaged between the first panel and the first portion of the second panel to attach the first portion of the second panel to the first panel;
• and
• a second manufacturer's joint strip engaged between the first panel and the secondary section of the fourth panel at a location along the first side wall intermediate the front and back walls.

A method of forming a display case from a one-piece blank comprising a first panel, a second panel, a third panel and a fourth panel connected in series at respective first, second and third vertical fold lines, the second panel including a tear-away section defining a first portion of the second panel separated from a second portion of the second panel by a separation line, and the fourth panel including a main body and a secondary section connected to the main body at a fourth vertical fold line, the method comprising:

• applying a first manufacturer's joint strip to the first panel;
• folding the first panel about the first fold line to engage the first panel on the tear-away section of the second panel;
• applying a second manufacturer's joint strip to the fourth panel;
• folding the fourth panel about the third fold line to engage the fourth panel on the first panel;
• and
• pivoting the first and third panels to a position perpendicular to the main body of the fourth panel, wherein the tear-away section moves with the first panel to separate from the second portion of the second panel along the at least one separation line and forms an erected case with a display window.
