Packaging device with fake-proof adhesive tape

Abstract

A packaging device with a fake-proof adhesive tape is proposed, including a body; a cover integrally formed with the body, for sealing an open end of the body; a fake-proof adhesive tape containing a thin sheet of substrate, and attached to the cover for adhering the cover to the body; a first adhesive layer applied over a first surface of the substrate, for attaching the fake-proof adhesive tape onto the cover; a fake-proof mark layer printed on a second surface of the substrate, and being adherent with the substrate; a colored layer for covering the mark layer and the second surface of the substrate; a transparent or semi-transparent viscous film applied over the colored layer; and a second adhesive layer formed on the viscous film, for adhering the fake-proof adhesive tape to the body.

What is claimed is:  
     
         1 . A packaging device with a fake-proof adhesive tape, comprising: a body, a cover connected to the body for sealing an open end of the body, and the fake-proof adhesive tape for adhering the cover to the body, the fake-proof adhesive tape comprising: 
 a substrate having a first surface and a second surface;    a mark layer made of an adherent material and applied on part of the second surface of the substrate;    a colored layer made of colored inks, and applied over the mark layer and part of the second surface of the substrate uncovered by the mark layer;    a viscous film attached to the colored layer;    a first adhesive layer applied over the first surface of the substrate for adhering the fake-proof adhesive tape to the cover; and    a second adhesive layer formed on the viscous film for adhering the fake-proof adhesive tape to the body;    wherein adhesion between the colored layer and mark layer is lager than that between the colored layer and viscous film, adhesion between the substrate and mark layer is larger than that between the viscous film and colored layer, and adhesion between the colored layer and substrate is smaller than that between the colored layer and viscous film.    
     
     
         2 . The packaging device with a fake-proof adhesive tape of  claim 1 , wherein the colored layer is of a color having sufficient contrast to the substrate or mark layer.  
     
     
         3 . The packaging device with a fake-proof adhesive tape of  claim 1 , wherein the colored layer is of a color having sufficient contrast to the viscous film.  
     
     
         4 . The packaging device with a fake-proof adhesive tape of  claim 1 , wherein the cover is integrally formed with the body.  
     
     
         5 . The packaging device with a fake-proof adhesive tape of  claim 1 , wherein the substrate is a thin plastic layer.  
     
     
         6 . The packaging device with a fake-proof adhesive tape of  claim 1 , wherein the substrate is transparent or semi-transparent.  
     
     
         7 . The packaging device with a fake-proof adhesive tape of  claim 6 , wherein the mark layer is similar in color and transparency to the substrate.  
     
     
         8 . The packaging device with a fake-proof adhesive tape of  claim 1 , wherein the viscous film is transparent or semi-transparent.  
     
     
         9 . The packaging device with a fake-proof adhesive tape of  claim 1 , wherein with the fake-proof adhesive tape being peeled apart, the colored layer is split to allow part of the colored layer on the mark layer to remain together with the substrate, and part of colored layer corresponding in position to area on the substrate uncovered by the mark layer to remain attached to the viscous film.  
     
     
         10 . A packaging device with a fake-proof adhesive tape, comprising: a body, a cover connected to the body for sealing an open end of the body, and the fake-proof adhesive tape for adhering the cover to the body, the fake-proof adhesive tape comprising: 
 a substrate having a first surface and a second surface;    a mark layer made of an adherent material and applied on part of the second surface of the substrate;    a colored layer made of colored inks, and applied over the mark layer and part of the second surface of the substrate uncovered by the mark layer;    a viscous film attached to the colored layer;    a first adhesive layer applied over the first surface of the substrate for adhering the fake-proof adhesive tape to the body; and    a second adhesive layer formed on the viscous film for adhering the fake-proof adhesive tape to the cover;    wherein adhesion between the colored layer and mark layer is lager than that between the colored layer and viscous film, adhesion between the substrate and mark layer is larger than that between the viscous film and colored layer, and adhesion between the colored layer and substrate is smaller than that between the colored layer and viscous film.    
     
     
         11 . The packaging device with a fake-proof adhesive tape of  claim 10 , wherein the colored layer is of a color having sufficient contrast to the substrate or mark layer.  
     
     
         12 . The packaging device with a fake-proof adhesive tape of  claim 10 , wherein the colored layer is of a color having sufficient contrast to the viscous film.  
     
     
         13 . The packaging device with a fake-proof adhesive tape of  claim 10 , wherein the cover is integrally formed with the body.  
     
     
         14 . The packaging device with a fake-proof adhesive tape of  claim 10 , wherein the substrate is a thin plastic layer.  
     
     
         15 . The packaging device with a fake-proof adhesive tape of  claim 10 , wherein the substrate is transparent or semi-transparent.  
     
     
         16 . The packaging device with a fake-proof adhesive tape of  claim 15 , wherein the mark layer is similar in color and transparency to the substrate.
