A resealable flap device in the form of a sheet having a base layer 30 of flexible material having an adhesive or glue on its lower side, and an upper layer 40 of stiff material, wherein the sheet is cut (15, fig. 1) through both layers to form a flap portion. There is a hinge region 18 which is not cut through, and the upper stiff layer is not present in the area behind the hinge region. The cut may curve at the hinge to prevent tearing, and may have discontinuities in the form of tie portions, and may define a frame 12 around the flap. Also claimed is a package incorporating such a closure device, a method of making such a closure device including the steps of providing said lower and upper layers, bonding them together and removing a portion of the upper layer in a region behind the hinge region, and cutting through the layers to define the flap portion. Also claimed is a resealable flap device having a second flap portion (14, fig. 5) |
