When realizing 40 closures complete sealed, closure 40 of the present invention provides the color indication of high-contrast.This used term " indication of high-contrast color " be used in reference to visual appearance absolute but not the variation of colourity.For example, high-contrast color indication can be from colourless to coloured, from white to black and/or variation from translucent to transparent, rather than the variation of the another kind of color from a kind of color to identical colourity.High-contrast color indication from the one or both sides of sack as seen.
Referring again to Fig. 1, closure 40 provides a kind of like this high-contrast color indication, when user's hand 70 along closure 40 translations, with the opposed member interlocking with mechanical interlocked closure member, its form is for changing to the purple outward appearance that is indicated by Reference numeral 50 from the initially clear/translucent/colorless appearance that is indicated by Reference numeral 60.
Fig. 2 shows similar flexible storage bag 10, and wherein the high-contrast color is designated as from the initial white colored appearance that is indicated by Reference numeral 60 and changes to the appearance of black that is indicated by Reference numeral 50.
Fig. 3 shows the flexible storage bag 10 based on the closure 45 of adhesive agent that utilizes pressure activation, and it provides the high-contrast color indication that changes to the green appearance form that is indicated by Reference numeral 50 from the initially clear/translucent/colorless appearance that is indicated by Reference numeral 60.The suitable closure based on adhesive agent comprises the selectively activated structure that is coated with adhesive agent; it by a plurality of by adhesive kit around compressible, can flatten that bulge is protected in case involuntary contact, and adhesive agent provides the sealed securely sealing when activating.Developed the suitable representational three-dimensional material of the thin layer pressure sensitive adhesives that comprises protected and anti-involuntary contact and the method and apparatus of making this material, and described in detail having in the following patent of commonly-assigned us with the present invention: the title of authorizing Hamilton and McGuire on September 2nd, 1997 is the US Patent 5662758 of " on being pressed in target surface time can be closed to this lip-deep composite material and manufacture method thereof releasedly "; And the title of authorizing Hamilton and McGuire on February 16th, 1999 is the US Patent 5871607 of " having material and manufacture method thereof by the material of deformable bearing protection "; And on November 8th, 1996 having the title of commonly-assigned us with the present invention and be the pending trial U.S. Patent application 08/745339 of " three-dimensional, nested-barrier material sheet and manufacturing method and apparatus thereof " (by) with the application of McGuire, Tweddell and Hamilton name; On November 8th, 1996 with the title of Hamilton and McGuire name application be " improved storage wrap material " 08/745340, all these documents all are incorporated herein by reference.
