  • Patent number: 5465900
    Abstract: A self-contained container assembly which may be quickly and easily formed into a three-dimensional container without the need for additional components or tools which includes a container blank and a tape structure. The container blank includes (i) a plurality of laterally interconnected panels, and (ii) a set of closure flaps hingedly connected to the longitudinal ends of the panels at one end.

  • Patent number: 5129519
    Abstract: A protective packaging container for encasing an article therein has air impermeable inner and outer walls. The inner wall defines a pouch for reception of the article, and the inner and outer walls are bonded together to define a hermetic chamber therebetween. Within the chamber, a mass of resilient compressible material is disposed, assuming a first compressed state when a reduced atmospheric pressure is maintained in the chamber. The resilient material assumes a second expanded state when the material is exposed to atmospheric pressure, when the chamber hermetic seal is breached. Upon expansion, the resilient material urges the inner wall about the article and provides an impact-absorbing cushion about the article. In one embodiment, a relatively inflexible protective panel member is provided on each side of the packaging container within the chamber between the resilient compressible material and the outer wall.

  • Patent number: 4883553
    Abstract: A method for forming pads of pressure sensitive adhesive coated sheets with similar discontinuities (e.g., printed indicia or openings) on the sheets substantially aligned. A strip of pressure sensitive adhesive coated material is helically wound around the periphery of a roller to form a roll comprising a multiplicity of overlying layers of the strip by rotating the roller about its axis to pull the strip along a predetermined path onto the roller. Discontinuities are formed on the strip along the predetermined path at locations that are progressively increasingly spaced apart to compensate for the increasing circumference of the roll and which result in at least one set of discontinuities being located along the periphery of the roller in substantial alignment radially outwardly of the roller; and pads containing such aligned discontinuities are then cut from the roll.
