Carton structure with seal-assistant ears

Abstract

A carton structure includes a circling peripheral plate providing two opposing open ends, and a plurality of seal plates for covering respective open ends of the peripheral plate. The seal plate includes at least a seal-assistant ear located at one lateral side of the seal plate. When the seal plate covers the respective open end, the seal-assistant ear can be folded toward the peripheral plate so that a correct position of the seal plate for sealing the open end of the peripheral plate can be obtained.

1 . A carton structure comprising: 
 a circling peripheral plate; and    a plurality of seal plates used for covering two open opposing ends of said peripheral plate, wherein said seal plate has two corresponding lateral edges to be aligned with an outer rim of said peripheral plate while said seal plates are covering said open ends of said peripheral plate, characterized in that at least one of said lateral edges of at least one of said seal plates extends a seal-assistant ear to be folded and creased towards said peripheral plate while said seal plates are covering said corresponding open ends of said peripheral plate, thereby aligning said one of said lateral edges with said outer rim of said peripheral plate.    
   
   
       2 . The carton structure of  claim 1 , wherein two said lateral edges of said seal plate have their own said ears, respectively.  
   
   
       3 . The carton structure of  claim 1 , wherein two said lateral edges of every said seal plate have their own said ears, respectively.  
   
   
       4 . The carton structure of  claim 1 , wherein said ear has a sticky strip to be stuck to said circling plate when said ear is folded towards said circling plate.  
   
   
       5 . The carton structure of  claim 1 , wherein said circling plate has a positioning hole at a relevant place to be passed through by corresponding said ear when said ear is folded towards said circling plate.  
   
   
       6 . The carton structure of  claim 1 , wherein said ear is located at an end section of said edge.  
   
   
       7 . The carton structure of  claim 1 , wherein said ear is located at a middle section of said edge.  
   
   
       8 . The carton structure of  claim 1 , wherein said seal plate has at least one dashed line extending along one side of said ear to link two said edges, thereby facilitating to open said carton which has assembled and sealed.
