Abstract
Abstract A device for mounting an independently formed closure upon an open-topped container wherein the container is stabilized by contents to constitute a stationary die, and with a forming die provided above said container for reciprocal movement toward and away from same. Said forming die contains a flat under surface for directing a flat closure upon the open upper end of said container and retaining same against inadvertent displacement; there being roller elements carried on said forming die for travel beneath the normally lower end thereof to direct marginal portions of the closure against said container and to hold same in such position to permit previously applied adhesive material to set.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
197 words
A device for mounting independently formed lids upon containers comprising means supporting a normally open top container in stationary position, means presenting a lid for closurewise disposition upon said container open top in elevated relationship thereto, a forming die provided above said lid, means effecting vertical reciprocal travel of said forming die toward and away from said container, whereby upon downward travel of said die said lid is moved into closurewise disposition upon said container open top with said container serving as a stationary die, said forming die comprising a platen guide having a flat bottom surface engageable with said lid upon downward travel of said forming die directing same onto said container, said platen guide having upstanding flanges from the marginal portions of said bottom surface, means interengaging upper portions of opposed flanges of said platen guide, a platen disposed within said platen guide beneath said flange interengaging means, resilient means interconnecting said platen and said means interengaging said flanges whereby said platen guide is urged downwardly of said platen, and forming members carried upon said platen for travel therewith, said forming members being disposed outwardly of said platen guide engaging marginal portions of said lid.
Claim 2
Independent Claim
197 words
A device for mounting independently formed lids upon containers comprising means supporting a normally open top container in stationary position, means presenting a lid for closurewise disposition upon said container open top in elevated relationship thereto, a forming die provided above said lid, means effecting vertical reciprocal travel of said forming die toward and away from said container, whereby upon downward travel of said die said lid is moved into closurewise disposition upon said container open top with said container serving as a stationary die, said forming die comprising a platen guide having a flat bottom surface engageable with said lid upon downward travel of said forming die directing same onto said container, said platen guide having upstanding flanges from the marginal portions of said bottom surface, means interengaging upper portions of opposed flanges of said platen guide, a platen disposed within said platen guide beneath said flange interengaging means, resilient means interconnecting said platen and said means interengaging said flanges whereby said platen guide is urged downwardly of said platen, and forming members carried upon said platen for travel therewith, said forming members being disposed outwardly of said platen guide engaging marginal portions of said lid.
Claim 3
Dependent Claim
59 words
A device as defined in claim 1 and further characterized by said means for effecting vertical reciprocal travel of said die comprising means connected directly to said platen whereby upon termination of downward travel of said platen guide, said platen will continue its travel against the bias of said resilient means into disposition upon said platen guide flat bottom.
Claim 4
Dependent Claim
81 words
A device as defined in claim 1 and further characterized by said lid being of greater area than said container open top and being scored spacedly from its edges to define foldable marginal portions, said forming die flat bottom surface being of substantially similar dimensions as said lid within the area bounded by said lid scores, said forming members engaging the marginal portions of said lid outwardly of said scores effecting bending of the same from the plane of said lid.
Claim 5
Dependent Claim
21 words
A device as defined in claim 3 and further characterized by said means engaging said lid marginal portions being elongated rollers.
Claim 6
Dependent Claim
59 words
A device as defined in claim 4 and further characterized by spaced apart support arms fixed upon said platen extending beyond the margins thereof and outwardly beyond the adjacent guide flanges, pivot arms swingably mounted upon said support arms for rockable movement within a vertical plane, said elongated rollers being carried at the lower ends of said pivot arms.
Claim 7
Dependent Claim
42 words
A device as defined in claim 5 and further characterized by said platen being quadrilateral, a roller presented outwardly of each side of said platen, resilient means urging said pivot arms laterally outwardly at their upper ends thereby biasing said rollers inwardly.
