Abstract
A two-part package includes a sleeve for receiving a tray. One surface of the sleeve has openings formed therein for receiving dimpled detents formed in the tray. As the tray is fully positioned in the sleeve, the detents engage the openings and retain the tray thereby inhibiting unwanted opening of the package and release of contents. Upon exertion of sufficient manual force on the sides of the sleeve, detent action is overcome and the package is opened as desired.
Claims8
A package comprising:
- a tray constructed from panels articulating from one another;
- a sleeve for receiving said tray;
- said tray including tapered side panels;
- detent means formed in a bottom panel of said tray;
- means formed in a bottom of said sleeve for receiving said detent means when said tray is inserted to a predetermined position within said sleeve thereby locking said tray in said sleeve;
- said sleeve having side walls cooperating with said tapered side panels of said tray so as to create voids between respective side panels and side walls when said tray is inserted in said sleeve;
- and
- said bottom wall of said sleeve being deformable and cooperating with said side walls of said sleeve so as to release said detent means from engagement with said receiving means upon the exertion of sufficient forces against said side walls of said sleeve thereby allowing said tray to be displaced from said sleeve.
A method for acheiving locking closure of a first package member within a second package member and unlocking thereof, comprising the steps of:
- providing the first member with tapered side panels and dimpled projections on a bottom panel;
- providing the second member with side walls and a deformable bottom wall having openings, each of said side walls cooperating with a respective one of said tapered side panels so as to form voids therebetween and said openings receiving said projections when said first and second members are brought into package-closing relationship with each other;
- moving said first member into said second member so as to bring the same into package-closing relationship with each other and to permit engagement between said projections and said openings thus acheiving locking closure;
- and
- deforming said bottom wall of said second member by exerting force upon said side walls of said second member adjacent the voids to disengage said projections from said openings thus unlocking said first and second members.
