Definitions
- the invention relates to a powder tight carton made from board or the like and to a blank for the carton.
- US 2501852 discloses a blank and a carton made therefrom having an end closure comprising two overlapping side flaps hinged to side panels of the carton and two non-overlapping powder flaps hinged to end panels, a first of the two side flaps being formed with a line of deformation in the form of a number of score lines spaced from its side panel hinge and extending in the same direction as the side flap hinge, a further line of deformation, also in the form of score lines, in each powder flap extending away from said powder flap hinge to lie adjacent to the side flap line of deformation, the arrangement being such that the second side flap terminates adjacent said side flap line of deformation and said further lines of deformation and lies between the first side flap and the respective powder flaps at each end of said second side flap.
- a disadvantage of this is that not all the flaps can lie entirely flat in the direction parallel to their hinges, so that the efficiency of sealing is compromised thereby.
- German Offenlegungsschrift No 22 60 766 relates to cartons in which, to obtain powder- tightness, immediately adjacent the hinge line, one of the two flaps hinged to the side panel is moulded along a portion of its length.
- the moulding which has to be made in an enclosed area, is similar to a deep-drawing and can be effected only with difficulty in particular with the more rigid grades of board.
- the two powder flaps which fold on to this first flap must then be cut away in the area of the moulding which is wasteful.
- the outer flap must also be provided with a further moulding corresponding to the first but made in the opposite direction which adds to the complexity of the process.
- the present invention provides a powder tight carton having a closure comprising two overlapping side flaps hinged to side panels of the carton and two non-overlapping powder flaps hinged to end panels, a first of the two side flaps and the powder flaps being formed with a line of deformation spaced from its side panel hinge, a further line of deformation in each powder flap extending away from said powder flap hinges to lie adjacent to the side flap line of deformation, the arrangement being such that the second side flap terminates adjacent said side flap line of deformation and said further lines of deformation and at each end lies between the first side flap and one of the powder flaps, characterised in that the lines of deformation are mould lines, that only part of the length of the hinge of each powder flap nearer the first side flap hinge is formed by a fold line and another part is formed by a moulding line offset from the fold line.
- the two flaps hinged to the side panels can be so short as to overlap only minimally and the powder flaps need by only of the shorter type.
- moulding lines of the type described can be relatively easily applied to the blank. The offset between the fold line and the moulding line ensures that the two flaps lie flat one on the other and on the powder flap.

The outer portion of flaps (12 and 13) remote from fold line (10 or 11) is moulded in the rearward direction.
- the two end panels (4 and 5) are each. provided with two powder flaps (16, 17) and (26, 27). These powder flaps are hinged to the corresponding end panels through fold lines (18, 19) and (28, 29) of which fold lines (18 and 28) are extensions of fold line (10), and fold lines (19 and 29) are extensions of fold line (11).

Abstract
Description
- The invention relates to a powder tight carton made from board or the like and to a blank for the carton.
- US 2501852 discloses a blank and a carton made therefrom having an end closure comprising two overlapping side flaps hinged to side panels of the carton and two non-overlapping powder flaps hinged to end panels, a first of the two side flaps being formed with a line of deformation in the form of a number of score lines spaced from its side panel hinge and extending in the same direction as the side flap hinge, a further line of deformation, also in the form of score lines, in each powder flap extending away from said powder flap hinge to lie adjacent to the side flap line of deformation, the arrangement being such that the second side flap terminates adjacent said side flap line of deformation and said further lines of deformation and lies between the first side flap and the respective powder flaps at each end of said second side flap. A disadvantage of this is that not all the flaps can lie entirely flat in the direction parallel to their hinges, so that the efficiency of sealing is compromised thereby.

German Offenlegungsschrift No 22 60 766 relates to cartons in which, to obtain powder- tightness, immediately adjacent the hinge line, one of the two flaps hinged to the side panel is moulded along a portion of its length. The moulding, which has to be made in an enclosed area, is similar to a deep-drawing and can be effected only with difficulty in particular with the more rigid grades of board. The two powder flaps which fold on to this first flap must then be cut away in the area of the moulding which is wasteful. The outer flap must also be provided with a further moulding corresponding to the first but made in the opposite direction which adds to the complexity of the process. - We have now discovered how to construct a folding carton which is at least equal in powder tightness to the carton described in German Offenlegungsschrift 22 60 766, but which is more economical in material.
- Accordingly, the present invention provides a powder tight carton having a closure comprising two overlapping side flaps hinged to side panels of the carton and two non-overlapping powder flaps hinged to end panels, a first of the two side flaps and the powder flaps being formed with a line of deformation spaced from its side panel hinge, a further line of deformation in each powder flap extending away from said powder flap hinges to lie adjacent to the side flap line of deformation, the arrangement being such that the second side flap terminates adjacent said side flap line of deformation and said further lines of deformation and at each end lies between the first side flap and one of the powder flaps, characterised in that the lines of deformation are mould lines, that only part of the length of the hinge of each powder flap nearer the first side flap hinge is formed by a fold line and another part is formed by a moulding line offset from the fold line.
- The two flaps hinged to the side panels can be so short as to overlap only minimally and the powder flaps need by only of the shorter type. Also, moulding lines of the type described can be relatively easily applied to the blank. The offset between the fold line and the moulding line ensures that the two flaps lie flat one on the other and on the powder flap.
- The invention will be further described with reference to the accompanying drawings in which: .
- Figure 1 shows a blank from which the powder tight carton is obtained, and
- Figure 2 is a vertical section through an erected carton.
- In Figure 1, (1) refers to a folding carton blank having two side panels (2 and 3), and two end panels (4 and 5). At the top and bottom, flaps (6, 7) are hinged to side panel (2) about fold lines (8, 9). About fold lines (10, 11) there are hinged to side panel (3) two flaps (12, 13) which are moulded along moulding lines (14,15). The outer portion of flaps (12 and 13) remote from fold line (10 or 11) is moulded in the rearward direction.
- The two end panels (4 and 5) are each. provided with two powder flaps (16, 17) and (26, 27). These powder flaps are hinged to the corresponding end panels through fold lines (18, 19) and (28, 29) of which fold lines (18 and 28) are extensions of fold line (10), and fold lines (19 and 29) are extensions of fold line (11).
- The aforesaid fold lines (18, 19, 28, 29) each terminate at mould lines (20, 21, 30, 31) extending from the outside edges of the powder flap (16, 17, 26, 27) approximately in the centre of the powder flaps perpendicular to the fold line. These moulding lines (20, 21, 30, 31) extend slightly beyond each fold line and continue as additional moulding lines (22, 23, 32, 33) extending to the other end of the powder flap in the same direction as the corresponding fold line but somewhat offset therefrom. The end panel (5) is hinged with a glue flap (34) which allows connection with the side panel (2).
- Figure 2 is a section through a fully erected and closed carton, the section being taken ver- - tically through the two side panels (2 and 3). The closure of the carton is formed as follows:
- The innermost layer is formed by tucking in powder flaps (16, 17) at the top and bottom. The non-moulded flaps (6, 7) then lie on the more deeply moulded portions of powder flaps (16,17) along moulding lines (20, 22) and (21, 23), the depth of the moulding being such as to accommodate about one-half the thickness of the aforesaid non-moulded flap. The remaining flaps (12, 13) are then folded on to the non-moulded portion of the powder flaps (6, 7), the portion moulded along line (14, 15) lying on the non-moulded flaps (6, 7) and slightly overlapping them.
- This design of blank results in an erected carton which is substantially powder tight.
