Definitions
- the invention relates to a powder tight carton made from board or the like and to a blank for the carton.
- German Offenlegungsschrift No 22 60 766 relates to cartons in which, immediately adjacent the hinge line, one of the two flaps hinged to the side panel is moulded along a portion of its length.

- 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 formed by two at least partly overlapping flaps hinged to side panels of the carton and by two powder flaps, characterised in that one of the two flaps (12, 13) hinged to side panels (2, 3) is formed with a moulding line (14, 15), the powder flaps (16, 17) are formed with moulding lines (20, 21), and the remaining flap (6, 7) terminates at one of said moulding lines (14, 15, 20, 21) and lies between one of the first flaps (12, 13) and one of the powder flaps (16, 17).

- the two flaps hinged to the side panels can be so short as to overlap only minimally and the powder flaps need be only of the shorter type. Also, moulding lines of the type described can be relatively easily applied to the blank.
- the powder flaps are hinged to the corresponding end panel along their entire length, the hinge articulation being obtained about a fold line and an offset moulding line.

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.
-
German Offenlegungsschrift No 22 60 766 relates to cartons in which, 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 formed by two at least partly overlapping flaps hinged to side panels of the carton and by two powder flaps, characterised in that one of the two flaps (12, 13) hinged to side panels (2, 3) is formed with a moulding line (14, 15), the powder flaps (16, 17) are formed with moulding lines (20, 21), and the remaining flap (6, 7) terminates at one of said moulding lines (14, 15, 20, 21) and lies between one of the first flaps (12, 13) and one of the powder flaps (16, 17).
- Preferably, the moulding line in one or both of the two flaps (12, 13) hinged to the side panel is formed so that the free end of the flap is proud of the hinged end. Equally, the corresponding moulding line on the powder flaps (16, 17) is preferred to be formed so that the portion of the flaps lying directly underneath the proud end of flap (12, 13) is depressed into the carton, so that between them one of flaps (12, 13) together with one of flaps (16, 17) sandwich one of the non-moulded flaps (6, 7).
- With this arrangement the two flaps hinged to the side panels can be so short as to overlap only minimally and the powder flaps need be only of the shorter type. Also, moulding lines of the type described can be relatively easily applied to the blank.
- In accordance with a further aspect of the invention, however, it is advantageous for the powder flaps to be hinged to the corresponding end panel along their entire length, the hinge articulation being obtained about a fold line and an offset moulding line. This 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 dust 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 vertically 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.
