Lid with tube reinforced skirt

Abstract

A lid for a container is disclosed. The lid has a paperboard tube that surrounds a plastic resin skirt. The skirt is attached to the perimeter of a central panel, which may also be formed of paperboard. The tube may have a projecting portion that is deformed toward the central panel. The tube provides an outwardly facing surface for the display of high quality graphics. A method of making the lid is also disclosed. The method includes placing the tube within a mold and injecting plastic resin into the mold to form the skirt. The central panel may also be placed in the mold prior to molding. Engagement of the mold with the tube may be used to deform the projecting portion of the tube.

1 . A lid for a container, said lid comprising: 
 a panel;    a skirt surrounding said panel and extending transversely to the plane thereof, said skirt being formed from a plastic resin and attached to said panel; and    a tube surrounding said skirt and attached thereto, said tube being formed of paperboard.    
   
   
       2 . A lid according to  claim 1 , wherein said panel is formed of paperboard.  
   
   
       3 . A lid according to  claim 1 , wherein said panel is formed of plastic resin.  
   
   
       4 . A lid according to  claim 3 , wherein said panel is transparent.  
   
   
       5 . A lid according to  claim 1 , wherein said tube comprises a spiral wound tube.  
   
   
       6 . A lid according to  claim 1 , wherein said tube is formed by joining ends of a paperboard substrate using a butt joint.  
   
   
       7 . A lid according to  claim 1 , wherein said tube is formed by joining ends of a paperboard substrate using an overlap joint.  
   
   
       8 . A lid according to  claim 1 , wherein said tube is formed by joining ends of a paperboard substrate using a scarf joint.  
   
   
       9 . A lid according to  claim 1 , wherein said tube comprises a first portion attached to said skirt and a second portion that projects beyond said skirt and is curved inwardly toward said panel.  
   
   
       10 . A lid for a container, said lid comprising: 
 a paperboard tube having an inwardly facing surface;    a plastic resin skirt attached to said inwardly facing surface and extending around said tube; and    a panel having an outer perimeter attached to said skirt.    
   
   
       11 . A lid according to  claim 10 , wherein said panel is formed of paperboard.  
   
   
       12 . A lid according to  claim 10 , wherein said tube comprises a first portion attached to said skirt and a second portion that projects beyond said skirt and is deformed inwardly toward said panel.  
   
   
       13 . A lid according to  claim 10 , wherein said tube has a round cross-sectional shape.  
   
   
       14 . In combination, a container and a lid, said container comprising: 
 a bottom;    a sidewall surrounding said bottom;    an opening defined by a rim positioned on said sidewall opposite to said bottom, wherein;    said lid comprises: 
 a paperboard tube having an inwardly facing surface;  
 a plastic resin skirt attached to said inwardly facing surface and extending around said tube, said skirt being adapted to receive said rim; and  
 a panel having an outer perimeter attached to said skirt.  
   
   
   
       15 . A lid according to  claim 14 , wherein said panel is formed of paperboard.  
   
   
       16 . A lid according to  claim 14 , wherein said tube comprises a first portion attached to said skirt and a second portion that projects beyond said skirt and is deformed inwardly toward said panel.  
   
   
       17 . A method of making a lid for a container, said lid having a panel attached to a skirt of plastic resin, said skirt being surrounded by a paperboard tube, said method comprising: 
 providing a mold;    opening said mold;    positioning said tube within said mold;    closing said mold; and    injecting a plastic resin into said mold to form said skirt surrounding said panel, said skirt adhering to an inwardly facing surface of said tube, said tube and said skirt being oriented transverse to said panel.    
   
   
       18 . A method according to  claim 17 , further comprising positioning a paperboard substrate within said mold, said paperboard substrate comprising said panel, said skirt adhering to said panel.  
   
   
       19 . A method according to  claim 17 , further comprising engaging a portion of said tube with said mold upon said closing thereof to deform a portion of said tube inwardly toward said panel.
