Abstract
A top closure arrangement for a container having opposed pairs of major and minor side wall panels forming a tubular structure and including opposed pairs of inner and outer closure flaps joined to upper end edges of the side wall panels with the inner closure flaps each having foldably joined to opposite sides thereof support tabs formed from material cut from adjacent portions of said outer closure flaps and folded downwardly for engagement with adjacent surfaces of related side wall panels to help support the inner closure flaps when they are in a closed position.
Claims6
A top closure arrangement for a container formed from a unitary blank of foldable paperboard and including opposed pairs of major and minor side wall panels foldably joined to each other to form a tubular structure open at the ends, said closure arrangement comprising:
- (a) a pair of inner closure flaps foldably joined to upper ends of respective minor side wall panels and folded inwardly therefrom and normal thereto;
- (b) a pair of outer closure flaps foldably joined to upper ends of respective major side wall panels and folded inwardly therefrom and normal thereto into overlapping relation with said inner closure flaps;
- (c) each of said inner closure flaps having foldably joined to opposite sides thereof support tabs formed from material cut from adjacent portions of said outer closure flaps;
- (d) said support tabs being folded downwardly from said inner flaps and normal thereto for engagement with adjacent surfaces of related major side wall panels to help support said inner closure flaps when said flaps are in a closed position;
- (e) said support tabs being secured against outer surfaces of said related major side wall panels.
A top closure arrangement for a container formed from a unitary blank of foldable paperboard and including opposed pairs of first and second side wall panels foldably joined to each other to form a tubular structure open at the ends, said closure arrangement comprising:
- (a) a pair of inner closure flaps foldably joined to upper ends of respective first side wall panels and folded inwardly therefrom and normal thereto;
- (b) a pair of outer closure flaps foldably joined to upper ends of respective second side wall panels and folded inwardly therefrom and normal thereto into overlapping relation with said inner closure flaps;
- (c) each of said inenr closure flaps having foldably joined to opposite sides thereof support tabs formed from material cut from adjacent portions of said outer closure flaps;
- (d) said support tabs being folded downwardly from said inner flaps and normal thereto for engagement with adjacent surfaces of related second side wall panels to help support said inner closure flaps when said flaps are in a closed position;
- (e) said support tabs being secured against outer surfaces of said related second side wall panels.
