Abstract
A tray for supporting linear lamps in large cartons may be made to nest in one orientation and on rotation by 180 degrees may stack to form a latched array of lamp cradles. The cradle walls are formed along their lengths with alternating lengths and gaps. The alternating wall sections of the cradle walls are asymmetric right to left along the cradle axis. The walls forming the rows of cradles are arranged to be paired with a non-nesting wall on rotation by 180 degrees. In this way, at least one point along the length of each wall is supported in the non-nesting orientation. By forming latching features at the support points, the trays can be locked together as a rigid array of lamp cradles.
Claims20
A packing tray to cradle a linear lamp comprising:
- a molded sheet of plastic resin having a first side and a second side defining an axis extending from the first side to the second side, the first side of the tray being formed with projections defining at least one horizontal cradle extending across a width of the packing tray wherein a first projection and a second projection are substantially parallel along the entire length of the first projection and the second projection and provide the cradle with a cross-sectional shape and the cross-sectional shape extends along the entire width of the molded sheet bound by the first projection and the second projection, the second side of the tray being formed with recesses symmetrically corresponding to the projections, whereby a first side of a first tray may be substantially nested into a second side of a similarly formed second tray when similarly oriented, and some or all of the projections and the corresponding recesses are not symmetrically formed with respect to a 180 degree rotation of the tray around the axis, whereby the first side of a first tray may be stacked on a second side of a similarly formed second tray when rotated 180 degrees around the axis without substantial nesting of the first tray into the second tray.
A packing tray to cradle a linear lamp comprising:
- a molded sheet having a first side and a second side;
- the first side having a first wall extending in an axial direction having a first height, the first wall defining a cradle extending across a width of the packing tray, a second wall extending in the axial direction and having the same height as the first wall;
- the first wall being segmented into at least a first upstanding portion and a second upstanding portion, the first upstanding portion and the second upstanding portion being divided by a notch region, the first upstanding portion and the second upstanding portion having the same height, being the height of the wall, and the notch region having a lower height than the wall height;
- the second wall portion also being similarly segmented into at least a similar first upstanding portion and a similar second upstanding portion, the first upstanding portion and the second upstanding portion also being divided by a similar notch region wherein the first wall and the second wall are substantially parallel and provide the cradle with a cross-sectional shape and the cross-section shape extends along the entire length of the first wall and the second wall;
- the second side being formed in a region extending parallel to the first wall with a first recess extending into the first upstanding portion and a second recess extending into the second upstanding portion;
- the second side being further formed along a region extending parallel to the second wall with a similar first recess extending into the first upstanding portion of the second wall and a second recess extending into the second upstanding portion of the second wall, the respective walls and recesses being sized and shaped so that when similarly oriented the recesses of a first tray may receive on insertion the respective upstanding portions of a second tray by inserted into the respective recesses of the first tray, to closely nest the respective trays;
- and
- the respective first wall's first upstanding portion, second upstanding portion and notch region and the second wall's first upstanding portion, second upstanding portion and notch region arranged complimentarily so that at least one notch region along the first wall abuts at least one region along the second wall and at least one region along the first wall abuts at least one notch region along second wall when a first tray is rotated 180 degrees in the plane of the tray.

A packing tray to cradle a linear lamp comprising:
- a formed sheet having a first side and a second side defining an axis extending from the first side to the second side, the first side of the tray being formed with projections defining at least one horizontal cradle extending across a width of the packing tray wherein a first projection and a second projection are substantially parallel along an entire width of the molded sheet and provide the cradle with a cross-sectional shape defined by the first projection and the second projection and both a first edge and an opposite second edge of the first projection and the second projection have the cross-sectional shape, the second side of the tray being formed with recesses corresponding to the projections, whereby a first side of a first tray may be substantially nested into a second side of a similarly formed second tray when similarly oriented, and some or all of the projections and the corresponding recesses are not symmetrically formed with respect to a 180 degree rotation of the tray around the axis, whereby the first side of a first tray may be stacked on a second side of a similarly formed second tray when rotated 180 degrees around the axis without substantial nesting of the first tray into the second tray.
