| 20110233099 | SHOCK-PROTECTING PACKAGING - A thermoformed packaging case has four wall-flanges which abut in ridge-within-groove nesting for interlocking and shock-absorbing closure of the case. Each edge has a pattern of ridges and grooves, and nesting of the edges of the flanges is enabled by a lateral shift in its ridge-groove pattern. Articles contained within the case are cushioned from shock by projections which protrude inwardly from inner surfaces of the walls to resiliently bear against the articles. Each buffer has a top surface surrounded by a valley and hump to provide shock-absorbing resilience. Locking of the case involves a flap hinged to a side-wall. To close a top-wall of the case onto the side-wall, projections of the top-wall enter recesses of the side-wall, and by folding the flap over to insert the projections into reverse recesses of the projections. The projections are snapped into recesses to effect triple-locking of the flap. | 09-29-2011 |
| 20110220541 | SHOCK-PROTECTING PACKAGING - A one-piece thermoformed packaging cap for article shock-protection which has two elongate wings integrally hinged and have upstanding shoulders which define a channel that receives part of the article. Ridges and grooves run along the shoulders of each wing such that when the wings are folded abut each other, the ridges and grooves of one wing nest within those of the other wing and provide cushioning and lateral interlocking between the wings. Caps can have four wings and wrap the entire perimeter of the article and may incorporate a locking tab to secure the wrap. Alternatively, an assembly of partial wrap-components can be locked via flap-tabs. For locking, a projection of one wing enters into a recess of another wing, and a locking flap of the latter wing is folded and a projection of the flap is snapped into the reverse recess of the thermoformed projection. | 09-15-2011 |
