Claims
- 1. A method of forming a packaging system with a closure lid in a closed position on a container body, said method comprising the steps of:
- A. integrally molding of container body having an interior compartment for retaining articles therein, a peripheral frame member circumscribing an access opening into the compartment to provide side walls of the closure lid and a flexible web connecting the container body and peripheral frame member to form a hinged connection between the container body and frame member; and
- B. adhering a flexible, moisture impervious sheet to the frame member to form a top wall of the closure lid.
- 2. The method according to claim 1, including the step of adhering the moisture impervious sheet to the container body to provide a moisture impervious seal over the access opening into the interior compartment.
- 3. A method of forming a packaging system with a closure lid in a closed position on a container body, said method comprising the steps of
- A. molding a container body having a bottom wall and peripheral walls extending upwardly from the bottom wall, said peripheral walls terminating in an outwardly extending flange disposed about the periphery of an access opening into an interior compartment of the container body;
- B. cutting the flange intermediate end margins thereof to form a peripheral frame member circumscribing the access opening of the container body to provide side walls of the closure lid:
- leaving a section of the flange uncut to provide a hinge joining the frame member to the container body; and
- C. adhering a flexible, moisture impervious sheet to the frame member to form a top wall of the closure lid.
- 4. The method according to claim 3, including the step of adhering the moisture impervious sheet to the container body to provide a moisture impervious seal over the access opening into the interior compartment.
- 5. A method of forming a moisture impervious packaging system with a closure lid in a closed position, said packaging system including a container body having a bottom wall and peripheral walls extending upwardly therefrom and terminating in an upper surface defining an access opening into an interior compartment of said body, said interior compartment being adapted to receive contents therein, a closure lid having a peripheral frame member and a flexible moisture impervious sheet, and a flexible web connecting a rear peripheral wall of the container body with a rear end of the peripheral frame member to provide a hinged connection between the frame member and container body, said peripheral frame member including a peripheral upper surface defining an open area which is greater than the area of the access opening into the interior compartment of said body, said method including the steps of:
- simultaneously molding the container body, flexible web and peripheral frame member with said frame member circumscribing the container body in the position it assumes when the lid is in a closed position; and
- adhering the flexible, moisture impervious sheet to the frame member to form a top wall of the closure lid and to the upper surface of the container body to provide a moisture impervious seal over the access opening into the interior compartment of said container body.
- 6. A method of forming a moisture impervious packaging system with a closure lid in a closed position, said packaging system including a container body having a bottom wall and peripheral walls extending upwardly therefrom and terminating in an upper surface defining an access opening into an interior compartment of said body, said interior compartment being adapted to receive contents therein, a closure lid having a peripheral frame member and a flexible moisture impervious sheet, and a flexible web connecting a rear peripheral wall of the container body with a rear end of the peripheral frame member to provide a hinged connection between the frame member and the container body, said peripheral frame member including a peripheral upper surface defining an open area which is greater than the area of the access opening into the interior compartment, said method comprising the steps of:
- a. simultaneously molding the container body, flexible web and peripheral frame member with said frame member circumscribing the container body in the position it assumes when the lid is in a closed position;
- b. forming a latching tab extending inwardly from a front end of the peripheral frame member, said latching tab terminating outwardly of a peripheral flange section of a front peripheral wall of said container body;
- c. depressing the front end of the frame member inwardly to position the latching tab into underlying relationship with the peripheral flange section on the front peripheral wall of the container body; and, while maintaining said depressing force,
- d. adhering the flexible, moisture impervious sheet in a taut condition to the frame member and the upper surface of the container body to maintain the latching tab in underlying relationship with the peripheral flange section on the front peripheral wall of the container body after the depressing force has been removed.
- 7. The method according to claim 6, including the step of initially forming the peripheral frame member with the latching tab end thereof radiused outwardly of the peripheral flange section of the front peripheral wall of said container body, and applying said depressing force to said radiused end to force it into a substantially linear shape with the latching tab underlying the peripheral flange section of the front peripheral wall of said container body.
