ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to hand filled bakery packages fashioned from paperboard. Generally, such packages or containers are not provided with a tamper evident device. In a typical package of this type a single anchor lock is used to secure the package hinge cover to the carton base after filling. Operators filling the packages sometimes encounter difficulty in engaging the lock. Further, opening the package was sometimes difficult for the consumer.
SUMMARY OF THE INVENTION
According to the present invention, a tamper evident bakery package is formed which requires only a single ripping or tearing action to open it, while also providing a tamper evident construction.
The free edges of two opposite and overlapping side wall panels are each provided with a cohesive coated tab. Each tab is bent out about ninety degrees from its side wall panel, with the two cohesive material coated surfaces placed in contact with each other. This precludes opening of the package. In one embodiment of the invention, the base of each tab carries a tear line, to thereby permit the adhered together tabs to be torn off together, so that the package may be opened. In another embodiment, the tabs are manually pulled apart for opening.
