Spline joints and container having same

A container defining a cargo receiving interior defined by a plurality of panels, the container comprising:

• a first panel having a first edge, the first edge having a first protrusion with a first contoured profile, the first contoured profile having at least one projection;
• a second panel having a second edge, the second edge having a second protrusion with a second contoured profile, the contoured profile having at least one projection;
• and
• a spline including first and second separate channels, the channels defining respective interior profiles, wherein the first channel receives the first protrusion of the first panel such that the first contoured profile is complementary to a portion of the interior profile of the first channel, and wherein the second channel receives the second protrusion of the second panel such that the second contoured profile is complementary to a portion of the interior profile of the second channel,
• wherein the interior profiles of the first and second channels include respective male projections extending into the respective first and second channels, each male projection having both a flat side and a curved side opposite the flat side.

A container defining a cargo receiving interior defined by a plurality of panels, the container comprising:

• a first panel having a first edge, the first edge having a first protrusion with a first contoured profile, the first contoured profile having at least one projection, wherein the first panel further includes a mid-section extending from the first edge;
• a second panel having a second edge, the second edge having a second protrusion with a second contoured profile, the contoured profile having at least one projection, wherein the second panel further includes a mid-section extending from the second edge;
• and
• a spline including first and second separate channels, the channels defining respective interior profiles, wherein the first channel receives the first protrusion of the first panel, and wherein the second channel receives the second protrusion of the second panel,
• wherein the first channel has an opening that opens in a direction perpendicular to the mid-section of the first panel, and the second channel has an opening that opens in a direction perpendicular to the mid-section of the second panel,
• wherein the first protrusion of the first panel is oversized with respect to the opening of the first channel to preclude passage of the first protrusion through the opening of the first channel, and the second protrusion of the second panel is oversized with respect to the opening of the second channel to preclude passage of the second protrusion through the opening of the second channel.
