Abstract
The blister pack has a reusable container mounted to a display card in a tamper resistant manner. The reusable container has a tray and a lid with the tray having frangible flanges thereon which are sealed to a presentation side of the display card. The lid has a deep channel which is received frictionally into the tray for securely closing the reusable container. Both the lid and the tray have enlarged finger engageable pull tabs for ease of opening the reusable container.
Claims18
A tamper resistant blister pack having a reusable container, comprising:
- a planar display card having a presentation surface, the presentation surface obviously deforming under stress;
- a reusable container having a tray and a lid;
- a deep channel in the lid for frictionally engaging walls of the tray so that when closed the lid is securely retained in the tray;
- a hinge connecting the lid to the tray so that when closed the lid is held substantially flushly to a rim of the tray;
- a pair of frangible flanges removably coupled to the tray rim, each of the frangible flanges sealed to the presentation surface of the display card;
- an elongated tray pull tab coupled to the tray front wall and extending substantially the width of the tray, the tray pull tab having a finger engageable area;
- means on the finger engageable area of the tray pull tab for assisting engaging the digits of a user;
- a lid pull tab attached to the lid and extending less than the width of the tray, the lid pull tab having a finger engageable area that extends beyond the finger engageable area of the tray pull tab;
- and
- a substantial ridge in the finger engageable area of the lid pull tab.

A reusable plastic container for use on a blister pack, comprising:
- a tray constructed in a generally rectangular shape and having a front wall, a hinge wall, and side walls, the front wall being substantially longer than each side wall;
- a lid constructed to flushly engage a rim of the tray peripheral rim;
- a deep channel in the lid for frictionally engaging walls of the tray so that when closed the lid is securely retained in the tray;
- an offset hinge connecting the lid to the tray so that when closed the lid is held substantially flushly to the tray rim;
- a pair of frangible flanges removably coupled to the tray rim, each of the frangible flanges for sealing to a display card;
- an elongated tray pull tab coupled to the tray front wall and extending substantially the width of the tray, the tray pull tab having a finger engageable area;
- means on the finger engageable area of the tray pull tab for assisting engaging the digits of a user;
- a lid pull tab attached to the lid and extending less than the width of the lid, the tray pull tab having a finger engageable area that extends beyond the finger engageable area of the tray pull tab;
- and
- a substantial ridge in the finger engageable area of the lid pull tab.

A method of making a reusable plastic container for use on a blister pack, comprising:
- constructing a tray in a generally rectangular shape, the tray having a front wall, a hinge wall and side walls, the front wall being substantially longer than each side wall;
- constructing a lid to flushly engage a peripheral rim of the tray;
- forming a deep channel in the lid for frictionally engaging walls of the tray so that when closed the lid is securely retained in the tray;
- offsetting a hinge between the lid and the tray, the hinge for connecting the lid to the tray so that when closed the lid is held substantially flushly to the tray rim;
- perforating a pair of removable frangible flanges on the tray rim, each of the frangible flanges for sealing to a display card;
- forming an elongated tray pull tab, the tray pull tab being coupled to the tray front wall and extending substantially the width of the tray, the tray pull tab having a finger engageable area;
- defining means on the finger engageable area of the tray pull tab for assisting engaging the digits of a user;
- forming a lid pull tab, the lid pull tab being attached to the lid and extending less than the width of the tray, the lid pull tab having a finger engageable area that extends beyond the finger engageable area of the tray pull tab;
- and
- defining a substantial ridge in the finger engageable area of the lid pull tab.
7 more elements
A method of using a blister pack that includes a reusable plastic container and a display card, the reusable container having a lid hinged to a tray, with the tray being sealed to the display card, comprising:
- engaging a lid pull tab, the lid pull tab being attached to the lid of the reusable plastic container and positioned substantially flush with the display card;
- prying, using the lid pull tab, the reusable plastic container from the display card;
- removing a pair of perforated frangible flanges from the tray;
- engaging, with a thumb nail, a nail groove in the lid pull tab;
- pressing a finger on the lid pull tab, the finger positioned opposite the thumb nail so that one hand securely holds the lid pull tab;
- engaging, with another thumb nail, a nail groove in a tray pull tab;
- pressing another finger on the tray pull tab, the another finger positioned opposite the another thumb nail, so that another hand securely holds the tray pull tab;
- and
- pulling the one hand away from the another hand so that the lid is pivotly disengaged from the tray in a smooth manner.
