The blank 10 can be formed into a flat collapsed carton as shown in FIG. 3c by a series of sequential folding operations in a straight line machine so that the carton 90 may not be required to be rotated or inverted to complete its construction. The folding process is not limited to that described below and may be altered according to particular manufacturing requirements.
Turning to the construction of the carton 90 as illustrated in FIGS. 2a to 4, glue G or other adhesive treatment is applied to a portion of an inner surface of the fourth wall panel 18 (see FIG. 2a ). The glue G is applied to a region which underlies the securing panel 58 when the blank is folded about fold line 55. Alternatively, glue G or other adhesive treatment may be applied to an inner surface of the securing panel 58. The blank 10 is folded (as indicated by direction arrow D1) about the fold line 55 such that the lower panel 56 is disposed in overlying relationship with the upper panel 52, the spacer panel 54 and a portion of the fourth wall panel 18. The securing panel 58 is brought into an overlying relationship with the fourth wall panel 18. The securing panel 58 is secured to the fourth wall panel 18.
Glue G or other adhesive treatment is applied to an inner surface of the first side wall 38 a as shown in FIG. 2b . Glue G or other adhesive treatment is applied to an inner surface of the second side wall 38 b as shown in FIG. 2 b.
The first inner side wall 40 a is folded about fold line 41 a to overlie the first side wall 38 a as indicated by direction arrow D2 in FIG. 2c . The first inner side wall 40 a is secured to the first side wall 38 a.
The second inner side wall 40 b is folded about fold line 41 b to overly the second side wall 38 b as indicated by direction arrow D3 in FIG. 2c . The second inner side wall 40 b is secured to the second side wall 38 b.
The second end closure panel 22 b is folded about fold line 23 b, as indicated by direction arrow D4 in FIG. 3a , to overlie the first wall panel 12 and consequently the first securing tab 30 b also overlies the first wall panel 12. The third end closure panel 24 b is folded about fold line 25 b to overlie the second wall panel 14. The fourth end closure panel 26 b is folded about fold line 27 b to overlie the third wall panel 16 and consequently the second securing tab 32 b also overlies the third wall panel 16. The fifth end closure panel 28 b is folded about fold line 29 b to overlie the fourth wall panel 18.
Glue G or other adhesive treatment is applied to an outer surface of the third end closure panel 24 b. Alternatively, glue G or other adhesive treatment may be applied to a corresponding portion of an inner surface of the second end closure panel 22 b. Glue G or other adhesive treatment is applied to an outer surface of the fifth end closure panel 28 b.
Alternatively, glue G or other adhesive treatment may be applied to a corresponding portion of an inner surface of the third end closure panel 26 b.
The blank 10 is folded about the fold line 17, as indicated by direction arrow D5 in FIG. 3b , such that the fourth wall panel 18 is disposed in overlying relationship with the third wall panel 16, and the securing panel 20 is disposed in overlying relationship with the second wall panel 14.
Glue G or other adhesive treatment is applied to an outer surface of the securing panel 20. Alternatively, glue G or other adhesive treatment may be applied to a corresponding portion of an inner surface of the first wall panel 12.
The blank 10 is folded about the fold line 13, as indicated by direction arrow D6 in FIG. 3c , such that the first wall panel 12 is disposed in overlying relationship with the second wall panel 14 and the securing panel 20. The first wall panel 12 is secured to the securing panel 20.
The blank 10 is thus formed into a flat collapsed tubular structure which can be readily shipped or distributed to a convertor plant, at which the flat collapsed tubular structure may be erected into a tubular structure and loaded with articles.
The flat collapsed tubular structure may be erected to form a tubular structure by displacement or translation of the first wall panel 12 relative to the third wall panel 16 such that the first wall panel 12 is spaced apart from the third side panel 16. In some embodiments this may be achieved by unfolding one of the wall panels 12, 14, 16, 18 with respect to one of the adjacent wall panels 12, 14, 16, 18. For example the first wall panel 12 may be unfolded about fold line 13 with respect to the second wall panel 14.
When the flat collapsed tubular structure is erected into the tubular form the second end closure panel 22 b, third end closure panel 24 b, fourth end closure panel 26 b and fifth end closure panel 28 b together form a composite base panel which is automatically erected when the flat collapsed tubular structure is erected. The blank 10 can be erected and assembly completed at the convertor plant without requiring application of glue or other adhesive treatment.
The recloseable end closure C can be erected by folding the first side wall 38 a about fold line 39 a, and hence simultaneously folding the first inner side wall 40 a so as to be substantially perpendicular to the first end closure panel 22 a. The first pair of web panels 42 a, 44 a are folded such that the second web panel 44 a is folded about fold line 47 a.
The second side wall 38 b is folded about fold line 39 b, and hence simultaneously folding the second inner side wall 40 b so as to be substantially perpendicular to the first end closure panel 22 a. The second pair of web panels 42 b, 44 b are folded such that the fourth web panel 44 b is folded about fold line 47 b.
The front wall 34 is folded about fold line 35. In doing so the first web panel 42 a is folded with respect to each of the first side wall 38 a and the second web panel 44 a about fold lines 43 a, 45 a respectively. Simultaneously the third web panel 42 b is folded with respect to each of the second side wall 38 b and the fourth web panel 44 b about fold lines 43 b, 45 b respectively.
Each of the second and fourth web panels 44 a, 44 b is brought into face contacting relationship with the front wall 34. The first web panel 42 a is brought into face contacting relationship with the second web panel 44 a. The third web panel 42 b is brought into face contacting relationship with the fourth web panel 44 b.
The inner front wall 36 is folded about fold line 37 so as to be brought into face contacting relationship with each of the first and third web panels 42 a, 42 b.
As the inner front wall 36 passes the edge of the first and second side walls 38 a, 38 b, defined by fold lines 41 a, 41 b respectively, the first and second locking tabs 46 a, 46 b are folded about the respective one of the fold lines 49 a, 49 b.
As the inner front wall 36 is brought into face contacting relationship with each of the first and third web panels 42 a, 42 b the first and second locking tabs 46 a, 46 b are received in a respective one of the first and second cutaways R1, R2.
The first locking tab 46 a interlocks with the first cutaway R1 and the second locking tab 46 b interlocks with the second cutaway R2 as shown in FIG. 5. In this way the recloseable end closure C is secured in an erected condition.
The carton 90 may be loaded with one or more articles through the open end by relative movement of the carton 90 with respect to the or each article.
Once the carton 90 has been loaded with an article or articles, the open end of the carton 90 is closed.
In some embodiments the article neck receiving structure N is provided. The article neck receiving structure N is erected once an article has been inserted. Article neck receiving structure N is erected by folding upper panel 52 about fold line 53. In doing so the lower panel 56 is folded about fold line 59 and the spacer panel 54 is folded about fold lines 55, 57 so as to be substantially perpendicular with respect to each of the upper and lower panels 52, 56, as shown in FIG. 4. The lower panel 56 may receive a portion (such as, but not limited to, a neck portion) of an article within the aperture A2.
An upper end of the article may be exposed to view through the aperture A1 in the upper panel 52.
The recloseable end closure C can be closed by folding the first end closure panel 22 a about fold line 23 a. Upper end portions of the second, third and fourth wall panels 14, 16, 18 are received in the recloseable end closure C.
The securing tab 50 is folded about fold line 51 when the recloseable end closure C is closed. The securing tab 50 is received in the third cutaway R3 so as to secure or hold the recloseable end closure C in the closed condition as shown in FIG. 6.

The inner front wall 446 is folded about fold line 445 so as to be brought into face contacting relationship with each of the first and second securing tabs 448 a, 448 b. The first and second securing tabs 448 a, 448 b are disposed between the inner front wall 446 and the front wall 442.
As the inner front wall 446 passes the edge of the first and second side walls 452 a, 452 b, defined by fold lines 455 a, 455 b respectively, the first and second locking tabs 456 a, 456 b are folded about the respective one of the fold lines 459 a, 459 b.
As the inner front wall 446 is brought into face contacting relationship with each of the first and second securing tabs 448 a, 448 b the first and second locking tabs 456 a, 456 b are received in a respective one of the first and second cutaways R3, R4.
The first locking tab 456 a interlocks with the first cutaway R3 and the second locking tab 456 b interlocks with the second cutaway R4 as shown in FIG. 15; in this way the recloseable end closure C is secured in an erected condition.
An assembled carton 490 is shown in FIG. 12. The carton 490 comprises a door 414/416 hingedly connected to the first side wall 412/418 by the fold lines 413, 415.
The fifth outer wall panel 440 forms a front wall 440 of the carton 490 extending partially between a lower end of the carton 490 and an upper end of the carton 490. The front wall 440 prevents unintentional egress of an article or articles disposed within the carton 490 when the door 414/416 is open.
The door 414/416 is held in the closed position by the recloseable end closure C. The front wall 440 overlaps with an upper portion of the door 414/416 when closed thereby preventing the door form being opened.
The contents of the carton 490 can be accessed by rotating the recloseable end closure C about the fold line 429 a thereby unfolding the first end closure panel 428 a.
Once the front wall 442 of the cap clears the upper edge of the door 414/416 the door may be opened. A user may then readily gain access to the contents of the carton 490 so as to remove them.
The contents may be replaced in the carton 490 and the carton reclosed by closing the door 414/416 and then the recloseable end closure C.
The recloseable end closure C is secured or held by interaction between the third cutaway R2 and the securing tab 450.
The door 414/416 may be opened to a fully opened position by folding the door 414/416 through 270 degrees such that the outside surface of the first outer wall panel 416 meets the outside surface of the second outer wall panel 418. The door 414/416 may be held in said fully opened position by closing the recloseable end closure C. The carton 490 may be deployed in this way for display purposes allowing consumers to view the contents of the carton 490.
It can be appreciated that various changes may be made within the scope of the present invention. For example, the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape.
It will be recognized that as used herein, directional references such as “top”, “base”, “front”, “back”, “end”, “side”, “inner”, “outer”, “upper” and “lower” do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another. Any reference to “hinged connection” should not be construed as necessarily referring to a single fold line only; indeed it is envisaged that a hinged connection can be formed from one or more of the following: a short slit, a frangible line or a fold line, without departing from the scope of the invention. It can be appreciated that various changes may be made within the scope of the present invention. For example, the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape.
As used herein, the terms “hinged connection” and “fold line” each refers to all manner of lines that define hinge features of the blank or substrate of sheet material, facilitate folding portions of the blank or substrate of sheet material with respect to one another, or otherwise indicate optimal panel folding locations for the blank or substrate of sheet material. Any reference to “hinged connection” should not be construed as necessarily referring to a single fold line only; indeed a hinged connection can be formed from one or more fold lines.
As used herein, the term “fold line” may refer to one of the following: a scored line, an embossed line, a debossed line, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, an interrupted cut line, aligned slits, a line of short scores and any combination of the aforesaid options, without departing from the scope of the invention.
It should be understood that hinged connections, fold lines can each include elements that are formed in the blank or substrate of sheet material, including perforations, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, a cut line, an interrupted cut line, slits, scores, any combination thereof, and the like. The elements can be dimensioned and arranged to provide the desired functionality. For example, a line of perforations can be dimensioned or designed with degrees of weakness to define a fold line and/or a severance line. The line of perforations can be designed to facilitate folding and resist breaking to provide a fold line, to facilitate folding and facilitate breaking with more effort to provide a frangible fold line, or to facilitate breaking with little effort to provide a severance line.
