Abstract
In order to fit a box lid to a box tray a pair of opposed plates are used. Each plate is pivotably mounted intermediately of its upper and lower edges such that upper edges of the opposed plates may pivot toward and away from each other. Each plate is biased to an inclined position whereat the upper edges of the opposed plates are more proximate than the lower edges of the plates. With this arrangement, a lid may be placed with respect to the pair of opposed plates such that opposed lower edges of the lid are positioned below the upper edges of said plates and at an outward side of said plates. A box tray may then be raised between the plates such that the box tray urges each of the plates away from its inclined position.
Claims13
A box-lid applicator, comprising:
- a pair of opposed plates, each plate pivotably mounted intermediately of its upper and lower edges such that upper edges of said opposed plates may pivot toward and away from each other, each plate biased to an inclined position whereat the upper edges of the opposed plates are more proximate than the lower edges of the plates;
- a raisable box tray support having a lowered position below said plates and a raised position between said plates such tat a box tray supporting surface of said box way support is at or above said upper edges;
- and
- a lid stop above said plates.
A method of applying a flexible lid to a flexible container, comprising:
- placing a lid with respect to a pair of opposed plates, each plate pivotably mounted intermediately of its upper and lower edges such that upper edges of said opposed plates may pivot toward and away from each other, each plate biased to an inclined position whereat the upper edges of the opposed plates are more proximate tan the lower edges of the plates such that opposed lower edges of said lid are positioned below said upper edges of said plates and at an outward side of said plates;
- raising a container between said plates such that said container urges each of said plates away from its inclined position;
- continuing to raise said container between said plates until said container is raised to a raised position which is at or above said upper edges of said plates;
- and
- stopping said lid with means for stopping said lid while said container is raised to said raised position such that said container pushes into said lid and said lid is fitted onto said container as said container is raised toward said raised position.
