Abstract

Lugs secure the mounting leaf of a plastic hinge within an inwardly offset recess formed in the upper lip portion of a metal container body. Flexible hinge straps are molded integrally with the mounting leaf and support a cover on the body for swinging between open and closed positions. In one embodiment, the cover is made of plastic and is molded integrally with the hinge straps. In a second embodiment, the cover is made of metal and is secured to a second mounting leaf which is molded integrally with the hinge straps.

Claims

1. A container having a body and a cover, said body being made of metal and having an upper lip portion defining an opening of predetermined size and shape, said cover being shaped as an inverted dish and having a top wall of the same general size and shape as said opening, and a peripheral skirt formed integrally with and depending from said top wall and adapted to telescope over the lip portion of said body when said cover is in a closed position, said container being characterized in that an intermediate section of said lip portion is offset inwardly from the adjacent sections of said lip portion so as to define a recess along the outer side of said lip portion, a hinge made of plastic and having a mounting leaf located within said recess, means for securing said leaf to said lip portion, and flexible web means molded integrally with the lower edge of said leaf, connected to the skirt of said cover and supporting said cover to swing upwardly and downwardly between open and closed positions about a hinge axis extending along said recess.

2. A container as defined in claim 1 in which said means for securing said leaf to said lip portion comprise a plurality of holes formed through said lip portion and spaced from one another along said one side of said lip portion, and a plurality of lugs molded integrally with and projecting inwardly from the inner side of said leaf and extending into said holes.

3. A container as defined in claim 1 in which said cover is made of plastic, said web means being molded integrally with the skirt of said cover.

4. A container as defined in claim 1 in which said cover also is made of metal, said hinge having a second flat mounting leaf disposed in face-to-fact relation with the inner surface of said skirt, means for securing said second leaf to said skirt, said web means also being molded integrally with the lower edge of said second leaf.

5. A container having a body made of metal and having a cover made of plastic, said body having an upper lip portion defining an opening of predetermined size and shape, said lip portion having at least one substantially straight side, said cover being shaped as an inverted dish and having a top wall of the same general size and shape as said opening, and a skirt formed integrally with and depending from the periphery of said top wall and adapted to telescope over the lip portion of said body when said cover is in a closed position, said container being characterized in that an intermediate section of said one side of said lip portion is offset inwardly from the end sections of said one side of said lip portion so as to define a recess extending along the exterior of said one side of said lip portion, said recess being located in opposing relation with the inner side of said skirt when said cover is in said closed position, a hinge made of plastic and having a flat mounting leaf located within said recess and disposed in face-to-face relation with said lip portion, means for securing said leaf to said lip portion, and flexible web means molded integrally with said leaf and with said skirt and supporting said cover to swing upwardly and downwardly between open and closed positions about a hinge axis extending along said one side of said lip portion.

6. A container as defined in claim 5 in which said means for securing said leaf to said lip portion comprise a plurality of holes formed through said lip portion and spaced from one another along said one side of said lip portion, and a plurality of lugs molded integrally with and projecting inwardly from the inner side of said leaf and extending into said holes.

7. A container as defined in claim 6 in which said lugs extend inwardly through said holes, and means integral with the inner ends of said lugs and captivating said lugs in said holes.

8. A container as defined in claim 6 in which said web means comprise a plurality of short straps molded integrally with the lower edge of said leaf and with the outer side of the lower edge of said skirt, said straps being spaced from one another along said one side of said lip portion.

9. A container as defined in claim 5 in which said web means comprise a plurality of short straps molded integrally with the lower edge of said leaf and with the outer side of the lower edge of said skirt, said straps being spaced from one another along said one side of said lip portion.

10. A container as defined in claim 9 in which an outwardly projecting bead is formed around the lower margin of said skirt, a plurality of notches formed in and spaced along said bead, the outer end portions of said straps being disposed in said notches.

11. A container having a body and a cover both made of metal, said body having an upper lip portion defining an opening of predetermined size and shape, said lip portion having at least one substantially straight side, said cover being shaped as an inverted dish and having a top wall of the same general size and shape as said opening, and a skirt formed integrally with and depending from the periphery of said top wall and adapted to telescope over the lip portion of said body when said cover is in a closed position, said container being characterized in that an intermediate section of said one side of said lip portion is offset inwardly from the end sections of said one side of said lip portion so as to define a recess extending along the exterior of said one side of said lip portion, said recess being located in opposing relation with the inner side of said skirt when said cover is in said closed position, a hinge made of plastic and having a first flat mounting leaf located within said recess and disposed in face-to-face relation with said lip portion, means for securing said first leaf to said lip portion, said hinge having a second flat mounting leaf disposed in face-to-face relation with the inner surface of said skirt, means for securing said second leaf to said skirt, and flexible web means molded integrally with the lower edges of said first and second leafs and supporting said cover to swing upwardly and downwardly between open and closed positions about a hinge axis extending along said one side of said lip portion.

12. A container as defined in claim 11 in which said means for securing said first leaf to said lip portion comprise a plurality of holes formed through said lip portion and spaced from one another along said one side of said lip portion, and a plurality of lugs molded integrally with and projecting inwardly from the inner side of said first leaf and extending into said holes.

13. A container as defined in claim 12 in which said lugs extend inwardly through said holes, and means integral with the inner ends of said lugs and captivating said lugs in said holes.

14. A container as defined in claim 12 in which said means for securing said second leaf to said skirt comprise a plurality of holes formed through and spaced along said skirt, and a plurality of lugs molded integrally with and projecting outwardly from the outer side of said second leaf and projecting into the latter holes.
