초록 ▼

A package is provided which incorporates a peel seal area or areas that provide readily detectable evidence that the package has been opened or tampered with. Message indicia are provided at or near the peel seal, and the appearance of the message indicia changes when the peel seal area, which has a contact clarity condition when sealed, is broken resulting in the onset of an opacity condition in a background area but not in an indicia area in order to inform a consumer or potential purchaser that the peel seal has been broken. The peel seal area is provided by impressing onto the package a heat seal bar having message indicia engraved thereinto.

In an improved tamper-evident package for hermetically sealing products between generally opposing front and rear panels having a peelable seal securing the generally opposing panels together at a peelable seal area, the peelable seal being openable with digital forces and not reclosable, the improvement comprising: tamper-evidence means for indicating that the generally opposing panels have been separated at a peelable seal, said tamper-evidence means being substantially within an area defined by the peelable seal; a background component of said tamper-evidence means within said peelable seal area, said background component being defined as areas where said generally opposing panels are peelably sealed together; an internal message component of said tamper-evidence means within said peelable seal area, said internal message component having indicia means for informing of seal disruption, said indicia means being unsealed areas bounded by and defined within said background component of the peelable seal, said internal message component being between said generally opposing panels; said tamper-evidence means has a contact clarity condition such that the internal message component and the background component are substantially the same in appearance, and said peelable seal area including said internal message component, background component and front panel is substantially transparent, when the generally opposing panels are in a sealed state at the peelable seal area; said background component of the tamper-evidence means has an opacity condition which develops initially upon and persists after disruption of the sealed state of the generally opposing panels at the peelable seal area, which opacity condition does not develop at said internal message component, whereby said internal message component remains substantially transparent, and said opacity condition causes a change in said peelable seal which changes the background component to have an appearance which is no longer substantially transparent and allows detectability of said substantially transparent internal message component of the tamper-evidence means; said generally opposing panels are flexible films that are sealed together by said peelable seal and by edge seals to form a pouch for hermetically sealing product within the pouch; and said background component and said internal message component of the tamper-evidence means are formed by a heat sealing bar having indicia areas engraved thereinto, which indicia areas are recessed portions that generally correspond to and form said unsealed area indicia means.
