A packaging unit comprises a package box having an openable portion for breaking and removing a seal of a lid by a push-in operation, and a film for sealing and packing the package box, wherein the film includes a fragile portion formed in or adjacent a position corresponding to the openable portion of the package box, the fragile portion being tearable by a push-in operation on the openable portion effected from outside the film. The packaging unit provides a quick and easy seal removing operation while restraining tear and damage of the film in time of distributing and displaying products to enhance tamper-proof efficiency by sealing and packing the package box with the film through a push-in operation to be effected on the openable portion of the package box.

The invention claimed is: 1. A packaging unit, comprising a package box having: an openable portion for breaking and removing a seal of a lid by a push-in operation, and a film for sealing and packing said package box, wherein said film includes a fragile portion formed in or adjacent a position corresponding to said openable portion of said package box, said fragile portion being tearable by the push-in operation effected on said openable portion from outside said film, and wherein said openable portion of said package box comprises a punch-out portion consisting of a part of the package body overlapping an insert piece of said lid in a closed position, said punch-out portion having a portion adhered to said insert piece and defined by tear-aiding perforations. 2. The packaging unit as defined in claim 1, wherein a tensile force is exerted on said film for facilitating tearing of the film when said openable portion is pushed in. 3. The packaging unit as defined in claim 1, wherein said fragile portion includes perforations formed in or adjacent a position corresponding to an edge of said openable portion, said edge is displaced to a maximum extent when the push-in operation is effected. 4. The packaging unit as defined in claim 1, wherein said fragile portion includes first perforations formed in or adjacent a position corresponding to an edge of said openable portion, said edge is displaced to a maximum extent when the push-in operation is effected, and second perforations formed in a position displaced proximally from the edge of said openable portion and extending along a direction intersecting opposite lateral edges of said openable portion. 5. The packaging unit as defined in claim 4, wherein said second perforations are formed in a right and left pair to traverse the lateral edges of said openable portion and wherein each of said second perforations extends to protrude laterally outwardly of an end of said first perforations. 6. The packaging unit as defined in claim 1, wherein said fragile portion formed in said film has a length equal or approximate to a width of said openable portion of the package box. 7. The packaging unit as defined in claim 1, wherein indication prints for the push-in operation are provided on said film in or adjacent the position where said fragile portion is formed and on said openable portion of said package body. 8. The packaging unit as defined in claim 1, wherein said film comprises a heat shrinkable film.
