Abstract
A knock-down folding carton is disclosed having a top closure and a bottom closure, shown with a top tab type closure and an automatic bottom, in which the sides are a plurality of sets of isosceles triangular members, half of which have their bases defining the top closure opening, and half of them having their bases defining the bottom. The top closure is oriented on a diagonal of the bottom closure as a result of the side wall configuration. Optionally, drop flaps can be employed on the top closure so that the only raw edge presented is at the end where the tab is inserted. In addition, a double bottom can be employed. While the configuration shown is primarily square in cross-section, other uniform cross-sections such as hexagonal, and octagonal are shown.
Claims14
A knock down folding carton having a planar top closure oriented diagonally with a planar bottom closure comprising, in combination,
- a planar top closure,
- a planar bottom closure,
- a plurality of sequential isosceles triangular side wall portions each having a base and a vertex,
- said isosceles triangular side wall portions being alternately inverted with relationship to the adjacent isosceles triangular side wall portion thereby forming top and bottom sets,
- the bases of one set of isosceles side wall portions defining the planar bottom closure perimeter and the bases of the other set defining the planar top closure perimeter,
- whereby the opposed triangle bases define a carton with a top and bottom with each diagonally opposed to the other and whereby said carton is free standing on its bottom and top.
A knock down folding carton having a top closure oriented diagonally with the bottom closure comprising, in combination,
- a blank form having not less than 10 even numbered faces,
- a top closure face,
- a bottom closure face,
- a plurality of isosceles triangular side wall face portions each having a base and a vertex,
- said side wall face portions being alternately inverted with relationship to the adjacent side wall face portion thereby forming top and bottom sets,
- the bases of one set of isosceles side wall face portions defining the bottom closure perimeter and the bases of the other set defining the top closure perimeter,
- whereby the opposed triangle bases define a carton with a top and bottom with each diagonally opposed to the other.
A knock down folding carton having a top closure oriented diagonally with the bottom closure comprising, in combination,
- a multi-sided top closure,
- a multi-sided bottom closure
- said top and said bottom having at least four sides, said sides being even in number,
- a plurality of isosceles triangular side wall portions each having a base and a vertex,
- said side wall portions being alternately inverted with relationship to the adjacent side wall portion thereby forming top and bottom sets,
- the bases of one set of isosceles side wall portions defining the bottom closure perimeter and the bases of the other set defining the top closure perimeter,
- whereby the opposed triangle bases define a carton with a top and bottom with each diagonally opposed to the other.
