DETAILED DESCRIPTION OF Tom, P1;IEEED E=OI)I5lEI9TS
As shown in FIGs. 2 and 3, a packaging device with a fake-proof adhesive tape according to c present invention is composed of a body 10 and a cover 11 fanned at an upper end of the body 10 for sealing an open end of He body 10. A fake-
proof adhesive tape is provi.det at the open end of the cover 11, and consist of a substrate 1 made of a plastic Win layer; a ma* layer 2 punted on part of a second surface 1 b of the substrate 1; a colored lays 3 applied over the mark layer and pan of the second surface lb of the substrate 1 uncovered by He mark layer 2 a transparent or semi-sparent viscous film 4 formed over the colored layer 3; a second adhesive layer 5 made of an adhesive applied over He viscous film 4, and a first adhesive layer 6 made of an adhesive formed over He first surface lo of the substrate i.
The substrate 1 is made of a transparent or semi-tnsparent plastic material which allows warning marks or patterns formed on the second surface lb of the substrate 1 to be easily observed when the substrate 1 is removed.
lobe mark layer 2 is made of an adhesive resin material similar in color and transparency to the substrate 1, so as to allow warning marks. patterns or words to be printed on the second space 1 b of the substrate 1 by a conventional printing process.
The colored layer 3 forms the warning marks, patterns or words by using ink of a color that produces considerably strong, contrast to the substrate I and He mark layer 2. l;s allows the warning marks or patterns to appear on the viscous film 4 or the substrate I when the substrate 1 is detached from the fake-proof adhesive tape
after opening or lining The cover 1 I to unseal the open end of Me body IO' so as to intone a designate receiver for the packaging device about unautboiized opening of the body 10 according to appearance of the wag marks or pattems. The colored layer 3 is applied over the second surface lb of the substrate 1. Me mark layer 2 and recessed portions 20 (as shown in FIG. 5) uncovered by the mark layer 2.
lye viscous film 4 is a thin film, allowing part of Me colored layer 3 formed OD. the mark layer 2 to be retained on a top surface of tbe viscous film 4 and show the warnung marlcs and patterns when the substrate 1 is peeled from the fake-proof adhesive tape. The second adhesive layer is applied on a bottom surface of the viscous film 4 to thereby adhere the viscous film 4 to the open end of the body 10.
The second adhesive layer 5 is formed by applying an adhesive oven the bottom surface of the viscous film 4, and used to attach Me fake-proof adhesive tape to the open end ofthe body 10 or the pack device.
As shown in FIG. 3, the fake-proof adhesive tape is used by cutting a piece of the f.ale-proof adhesive tape of an appropriate length and attaching the piece to the open end of Me body I O in a way sLnular to a conventional adhesive tape. The first adhesive layer 6 applied on the substrate lof the fale-proof adhesive tape is used to adhere the substrate 1 to the cover J I or to Me open end of Me body 10. Preferably.
the first adhesive layer 6 of the faire-proof adhesive tape is attached to the cover 1, and the second adhesive layer 5 fanned over the viscous film 4 is affixed to the open.
end of the body I O. malting the body I O in a coeditor of being sealed by the cover 1 1.
Adhesion between component layers of Me fake-proof adhesive layer is detailed as follows. Adhesion between the colored layer 3 and mark layer 2 is larger than that between the colored laver 3 and viscous film 4. Further adhesion between the substrate 1 and mark layer 2 Is larger than that between the viscous film 4 and
- 6 - colored layer 3. Andr adhesion between the colored layer 3 and substrate I is smaller Man hat between the colored layer 3 and viscous layer 4.
As shown in FIG. or 5, if the sealed pack ng device is forcibly or unauthorizedIy opened and We fake-proof adhesive tape is peeled apart, in accordance with Me above adhesion correlation between the component layers of the fake-prQof adhesive tape, Me mark layer 2 and part of the colored layer 3 adb.ered to the mark layer 2 would be detached together win the substrate 1 from the fake-proof adhesive tape in accompany USA lifting or opening the cover 1 1 with respect to the body 10, whereas part of the colored layer 3 corresponding in position to the recessed portions 20 would remain attached to the viscous film 4 that also keeps adhered to the open.
end of the body 10 by means of the second adhesive layer 5.
Consequently, as shown in FIG. 6, Dom a voyeur of the viscous film 4 adhered to the open end of the body 10. the part of the colored layer 3 remaining on the viscous film 4 can be observed and shows Me wanting marks patterns or words.
Therefore. with reveal of Me waming marks, patterns or words, it indicates peeling-
apaTt of ó fake-proof adhesive tape. On the other hand as shown in FIG 7. the part of the colored layer 3 remaking on the mark layer 2 attached to the substrate 1 allows a complementary pattern of the waming marks or words to appear on the second surface lb of Me substrate 1 win respect to Me pattern shown in FIG 6.
After the fake-proof adhesive tape is peeled apart, although the viscous film 4 still Uremic adhered to the open end of the body 10 via the second adhesive layer 5, however the viscous film 4 itself is not adhesive enough to restore adherence to the substrate 1; in otl:er words, once the fake-proof adhesive tape is peeled apart it fails to be re-sealed agauL which allows only one time of sealing between tle body 10 and the cover 11 and thereby provides secmity and fake-proof effects.
Besides, the substrate 1 may also be made of a colored plastic matenal, and the Tnark layer 2 is not particularly limited in respect of its transparency and color. In this case however. the colored layer 3 should have a color in contrast to the viscous film 4 for detecting He warning marks or patterns inticaa.ng unauthorized opening of the pacicaging device once the substrate 1 is peeled off from the fake-proof adhesive tape. The invention has been described using exemplary preferred embodiments.
EIowever, * is to be understood that Me scope of We invention is not [united to the disclosed embodiments. On the contrary' it is intended to cover various modifications and similar amngem.ents. The scope of me claims, therefore, should be accorded the broadest interpretation so as to encompass ail such modifications and similar anangements. )
