  • Patent number: 5213214
    Abstract: A confection/gift holding structure for disposition in greeting cards and greeting card envelopes includes a base constructed of a generally planar sheet of material having a plurality of relatively shallow recesses formed in one surface thereof to define open receptacles for receiving and holding confections, where such confections have thicknesses and parametric shapes which generally conform to the depths and shapes of corresponding receptacles. A channel is also formed in said one surface of the sheet of material at a location to circumscribe the recesses, with the channel having facing sidewalls and notches formed in at least one of the sidewalls and spaced apart about the channel. A generally flexible planar lid is also provided, where the perimeter of the lid is formed to overlie the channel when the lid is placed on the base. The lid includes a lip projecting downwardly from the perimeter to fit in the channel and allow the lid to lie flat on the one surface of the base.

  • Patent number: 5052560
    Abstract: A confection holding structure for disposition in greeting cards and greeting card envelopes includes a generally planar sheet of material having a plurality of relatively shallow recesses formed in one surface thereof to define open receptacles for receiving and holding confections, where such confections have thicknesses and parimetric shapes which generally conform to the depths and shapes of corresponding receptacles. The sheet of material also includes downwardly projecting support protuberances located generally adjacent to at least some of the receptacles to thereby provide support for inhibiting the crushing or deformation of the receptacles and confections contained therein when, for example, an envelope containing the holding structure is passed through a stamp cancelling machine.
