Title: Tamper-proof package and method

Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     This invention relates to a tamper-proof package to indicate to the purchaser whether or not the package has been tampered with and hence to warn the purchaser that the contents, such as medicine has been tampered with as well. 
     2. Background 
     The problem in the art to which this invention apertains is the need for a tamper-proof package that will provide multiple successive indications to the purchaser whether or not the package has been tampered with in gaining ultimate access to the contents. 
     SUMMARY OF THE INVENTION 
     Accordingly, the object of the invention is to contribute to the solution of the discussed problem of the art by providing a tamper-proof package comprising a first container that is end-flap sealed and in which the contents, such as medicine, is enclosed. The first container is sealed by a celophane wrap that can be opened along its tear strip band. The cellophane-wrapped first container is enclosed within a second container that has a heat sealed top cover, a horizontal advertising band and a vertical octopus leg tear strip. The second container is enclosed by a pouch whose ends are closed and heat and/or pressure sealed, and may be opened by tearing same across the ends. Opening the pouch provides two initial indications of tampering; opening the heat-sealed top cover of the second container, tearing the horizontal advertising band and separating the second container by tearing the vertical tear strip provide three additional indications of tampering; tearing apart the cellophane wrapper via its tear strip provides the sixth indication of tampering; and opening the closed end sealed end-flap of the first container would provide the seventh indication of tampering.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     In FIG. 1 of the drawings, reference numeral 1 generally refers to the invention of the tamper-proof package comprising a pouch 3 whose top and bottom ends 5 and 7 are closed and heat and/or pressure sealed. 
     Pouch 3 is made of lightweight flexible material such as paper, regenerated cellulose, etc. Enclosed in pouch 3 is a second container 9 of suitable semi-rigid material such as lightweight plastic, paper and the like. Second container 9 has a heat-sealed top cover 11 which may be torn off and thereby indicate tampering. Second container 9 has a verticle octopus leg tear strip 13 which can be torn open by appropriate manipulative grasping of its tab 15. A horizontal advertising band 17 overlies tear strip 13. Grasping tab 15 and separating container 9 by means of its tear strip 13 will first tear apart the advertising band 17 to thereby indicate tampering; and then separating the second container 9, as shown in FIG. 4, to thereby indicate further tampering. 
     The contents, article or medicine that is to be protected against tampering is enclosed in a first container 19 that has its end flap 21 adhesively sealed. Container 19 is made of suitable material such as plastic or the like. Tearing open the end flap 21 would thereby indicate tampering. Container 19 is sealed by cellophane wrapping 23 that can be opened along its tear strip 25 by appropriate manipulative grasping of its tear tab 27. Tearing open the cellophane wrapping 23 would indicate tampering. The cellophane-wrapped first container 19 is enclosed within the second container 9. 
     The tamper-proof oackaging 1 provides seven separate and distinct prior indications to the purchaser that the contents, article or medicine within the first container 19 may have been subjected to tampering. 
     Two indications of tampering are provided when the top and bottom ends 5 and 7 of the pouch 3 are torn across. Tearing off the top cover 11 of the second container 9, tearing apart the advertising band 17 and tearing open the second container 9 via its octopus leg tear strip 13 would provide three additional indications of tampering. Tearing open the cellophane wrap 23 via its tear strip 25 would provide an additional indication of tampering. Tearing open the adhesively sealed end flap 21 of the first container 19 would be as additional indication of package tampering. 
     A person who intends to tamper with the contents, article or medicine contained within the first container 19 would not provide and warn a prospective purchaser of seven successive positive indications of package tampering to gain access for purposes of tampering with the packaged contents, article or medicine. Any indications that the package 1 had been tampered with would warn the prospective purchaser not to buy the package; and, if unsuspectingly bought, would warn the purchaser not to use the contents, article or medicine. Hence, the package 1 would be tamper-proof.
