Definitions
- This invention relates to crash-bottom cartons and blanks therefor.
- Crash-bottom cartons comprise an array of four wall panels hinged one to the next, the ends of the array being joined together to form a flattenable tubular arrangement of the wall panels with two panels on one side and two panels on the opposite side of the flattened tube, bottom-forming panels being hinged to the wall panels and arranged so that when the wall panels are moved from the flattened configuration to the rectangular tubular configuration the bottom-forming panels automatically move into a co-planar configuration at the bottom of the erected carton.
- subsidiary panels on the edges of the bottom-forming panels, which subsidiary panels provide partitions within the carton.
- With previously known crash-bottom cartons it has only been possible to provide square compartments by such partitions, if the carton is to be erectable from its flattened condition automatically.
- Cartons are known in which rectangular compartments are provided, but such cartons cannot easily be erected by machine.
- Cartons according to the present invention may have rectangular compartments and are easier to erect.
- a crash-bottom carton in which first and second bottom-forming panels have hinged thereto ; respectively first and second partition-forming panels, at least one of the partition-forming panels being shaped to provide a notch or slot to receive the other crosswise on erection of the carton from the flattened condition, the first partition-forming panel having a portion which on erection passes over that edge of the second partition-forming panel which is remote from its bottom-forming panel to bring the partition-forming panels in the crosswise configuration.
- the distance from the hinge between the second wall-forming panel and the second bottom-forming panel to said edge of the second partition-forming panel is preferably less than or equal to the distance from the corresponding hinge of the first bottom-forming panel to the closest edge of said portion of the first partition-forming panel, which passes over said edge of the second partition-forming panel.
- said portion is hingeable to enable it to pass over said edge.
- each partition-forming panel has a notch or slot, the notches or slots co-operating with each other.
- the said edges of the two partition-forming panels have lead-in portions to the slots which are shaped to direct the partition-forming panels into the crosswise configuration.
- the invention also encompasses a blank of foldable sheet material for such a carton.
- the blank for first carton is cut and scored from foldable board material and has four side wall-forming panels 10, 12, 14 26. These panels are arranged in a longitudinal row. At one end of the row, the panel 16 has a tab 18 which, on forming the carton into the flattened condition shown Fig.2, is adhered to the panel 10 at the other end of the row, so that the flattened carton of Fig.2 is essentially tubular. All the panels 10,12,14,16 are rectangular, being hinged together by their shorter edges.
- the panel 10 has a lid-forming panel 20 hinged to one of its longer edges, the panel 20 having a tuck-in flap 22 hinged to its edge opposite the panel 10.
- the panels 12,16 also have flaps 24 hinged to their longer edges on the same side as the lid 20.
- each of the panels 10,12,14,16 has a bottom-forming panel 26,28.
- the panels 28 hinged to the side wall-forming panels 12,16 are roughly rectangular, and to their edges remote from the side wall-forming panels are hinged respective partition-forming panels 30.
- the bottom-forming panels 26 are hinged at 40 to the side wall-forming panels 10,14 and are of approximately the same depth (measured away from the hinge 40) as the panels 28 and 30 taken together.
- One edge 32 of the panel 26 tapers diagonally, and in the carton when erected this edge 32 lies on a diagonal of one of the rectangular compartments.
- the opposite edge of the panel 26 has a flap 34 connected thereto by a hinge line 36 which is at 45 to the hinge line between the panels 26 and 10 or 14.
- This hinge line 36 is scored and perforated such that the flap 34 hinges downwardly from the panel 26 (that is, in the opposite sense to all the other hinge and fold lines of the blank).
- the edge 38 of the panel 26 is nearly perpendicular to the hinge line 40.
- the edge 38 extends as a small cut 42 in the blank between the flap 34 and panel 26, to meet the hinge line 36.
- each panel 26 is hinged to a partition-forming panel 46.
- the panel 46 has a laterally extending portion 48, and a notch 50 is formed which partially divides the portion 48 from the rest of the panel 46.
- the notch 50 extends from the edge 52 of the portion 48 which is closest to the hinge 40.
- the edge 52 has a cam-shaped recess 54 which provides a lead-in to the notch 50.
- Each partition-forming panel 30 has a notch 56 which co-operates with the notch 50 when the carton is erected.
- the panel 30 has an upper edge which is cam-shaped at 58 to lead in to the notch 56.
- Each panel 30 also has a C-shaped cut 60 leading into the panel 30 from the hinge 62 between the panels 30 and 28, to form a ledge 64 extending out of the panel 28.
- the blank is folded into the collapsed, flat carton of Fig.2 by folding the bottom-forming panels 26,28 over their respective wall-forming panels 10,12,14,16, folding back the flaps 34, folding the panels 10 and 16 (with their associated paneis; over the panels 12 and 14, and adhering the tab 18 or the inside of the panel 10 and the flaps 34 to tha undersides of the panels 28.
- the flattened collapsed carton shown in Fig.2 can then be erected, for example by a macchine of the type disclosed in our German OLS No.2807968,
- the carton is erected by pushing the two ends 72,74 towards each other. This causes the side walls 10,12,14,16 to assume a rectangular configuration. and as this happens the bottom-forming panels 26,28 are pulled downwardly to form the bottom of the carton by the flaps 34 which are hinged about their 45 0 hinge lines 30,36 and adhered to the panels 28, As the panels 26,28 are pulled downwardly, the partition-forming panels 30,46 are taken inwaraly, and the recess 54 meets the upper edge 59 of the half 70 of the panel 30.
- the cam shapes of the recess 54 and edge 59 guide the two notches 50,56 into engagemen with the partitions crosswise. This is seen particularly in Fig.3, and the finally erected carton is seen in Fig.4.
- the edge 38 causes the half 68 of the other partition-forming panel to flex. Obviously, if the halves 70 flexed with the halves 68 they would hinder the proper engagement of the partitions. It is for this reason that the fire or weakening 66 is provided so that the half 70 does not tend to flex with the half 68.
- the erected carton thus has partitions defining six (i.e. 2 x 3) rectangular compartments into which goods can be packed.
- the compartments can be almost any rectangular shape, and for example could be square if desired.
- the carton could have a different number of compartments if desired; for example a carton with four compartments (2 x 2) could be made by providing only one each of the panels 30 and 46. In the carton just described, the partitions 46 are higher than the partitions 30.
- the depth of the panel 26 (measured from the hinge 40) is approximately the same as or greater than the corresponding depth of the panels 28 and 30 taken together, since this helps to ensure that the edge 52 passes over the edge 59 so that the notches 50,56 are brought into engagement.
- Figs. 5 to 8 the second carton works on the same principle as the first, and in the drawings similar parts have like reference numbers, although their dimensions may be a little different.
- the flaps 24 have been separately identified as 24a and 24b.
- the major differences between the first carton and the second arise in the partition-forming panels.
- the second carton when erected has partiticns which form compartments which are more nearly square than in the carton of Figs. 1 to 4; in fact the compartments of the second carton are only a few millimetres out of square.
- the bottom-forming panels 28 have partition-forming panels 72.
- the panels 72 have an upper edge 74 having a notch 76.
- the notch 76 is barb-like and has an abutment edge 78 and a lead-in edge 80.
- the lead-in edge 80 is cam-shaped, like the cam-shaped edge 58 in Figs. 1 to 4 and functioning in a similar manner.
- the cut 60 and line of weakening 66 of Figs. 1 to 4 are nor provided in the present embodiment.
- the bottom-forming panels 26 have partition-forming panels 82 in place of the partition-forming panels 46 of Figs. 1 to 4. These panels 82 have laterally extending portions 84, and the portions 84 are provided with flaps 86 which are hinged to the portions 84 about hinge lines 88 which are generall, parallel to the hinge lines 40. The flap 86 is on that side of the line 88 closest to the hinge line . The flap 86 defines a notch or slot 90 with the adge 92 of the panel 82. The opposite edge 94 of the panel 82 has a projecting portion 96.
- the flaps 86 have laterally extending tahs 98,100 respectively, the function of which will be described later.
- the tab 100 is flexible in relation to its flap 86, by reason of a line of weakenign 10.
- the carton is erected from the blank of Fig.5 to the flattened condition shown in Fig.6 in the sand manner as before, the flaps 34 being adhered to the bottom-forming panels 28 as before.
- the tab 98 is flicked so that it lies on the other side of the panel 24a.
- the tab 100 lies behind che flap 24b, but there is no need for a special slicking operation to achieve this since the tab 100 will already be in place under the flap 24b when the tab 18 is adhered to the side wall-forming panel 10.
- the carton is erected from the flattened condition in the same way as the carton of Figs.l to 4. It will be appreciated that initially the tabs 98,100 are caught behind the flaps 24a,24b as the side walls 10,12,14,16 begin to assume a rectangular configuration. The purpose of this is to ensure that each flap 86 catches behind the edge of the corresponding panel 72, since otherwise the carton would tend not to erect properly. This is particularly true of the tab 98, since the corresponding panel 72 necessarily has a cut out portion 104 (see Fig.5) corresponding to the tab 98. However, because the tab 100 occurs at the end of the blank there is no such cut out portion on the other panel 72.
- each notch 76 is close to a corresponding projecting portion 96.
- each projecting portoon 96 catches in its notch 76, and the abutment edge 78 bears against the projecting portion 96.
- the flaps 86 are thus pushed over the upper edge 74 of the panel 72, down the cam shaped edge 80, and finally the flap 86 drops over the panel 72 to lock the partitions in place in the configuration seen in Fig.8.
- the slot or notch 90 engages with the notch 76, and because the partitions are locked the entire carton is strong and secure.
- cartons are supplied in the flat condition shown in Fig.2 or Fig.6 to the packer, who erects the carton (which only requires one stroke and can be done automatically by a machine such as that described in our German OLS No. 2807968). He then inserts the goods (e.g. glasses, which can go on their sides and are > therefore presented in a more attractive display) into the compartments.
- the flaps 24 or 24a and 24b are then folded in, and the lid closed by tucking the flap 22 into the carton next tp the side wall 14.
- the 5 partitions 30 or 72 are a little higher than half the diameter of a glass.
Abstract
A crash-bottom carton is erected from a flattened tubular condition to a generally rectangular condition. At the same time, bottom-forming panels (26, 28) hinged to its wall-forming panels (10, 12, 14, 16) are automatically brought down into a co-planar configuration at the bottom of the carton, and a pair of first partition-forming panels' (46, 82) pass over a pair of second partition-forming panels (30, 72). The partition-forming panels have co-operating slots or notches (56, 50, 76, 90) which enable them to receive each other in a crosswise configuration after they have passed over each other; this happens automatically as the carton is brought into the rectangular configuration.
Description
- This invention relates to crash-bottom cartons and blanks therefor.
- Crash-bottom cartons comprise an array of four wall panels hinged one to the next, the ends of the array being joined together to form a flattenable tubular arrangement of the wall panels with two panels on one side and two panels on the opposite side of the flattened tube, bottom-forming panels being hinged to the wall panels and arranged so that when the wall panels are moved from the flattened configuration to the rectangular tubular configuration the bottom-forming panels automatically move into a co-planar configuration at the bottom of the erected carton. It is known to provide subsidiary panels on the edges of the bottom-forming panels, which subsidiary panels provide partitions within the carton. With previously known crash-bottom cartons, it has only been possible to provide square compartments by such partitions, if the carton is to be erectable from its flattened condition automatically. Cartons are known in which rectangular compartments are provided, but such cartons cannot easily be erected by machine. Cartons according to the present invention may have rectangular compartments and are easier to erect.
- According to the present invention there is provided a crash-bottom carton in which first and second bottom-forming panels have hinged thereto ; respectively first and second partition-forming panels, at least one of the partition-forming panels being shaped to provide a notch or slot to receive the other crosswise on erection of the carton from the flattened condition, the first partition-forming panel having a portion which on erection passes over that edge of the second partition-forming panel which is remote from its bottom-forming panel to bring the partition-forming panels in the crosswise configuration.
- In one form, the distance from the hinge between the second wall-forming panel and the second bottom-forming panel to said edge of the second partition-forming panel is preferably less than or equal to the distance from the corresponding hinge of the first bottom-forming panel to the closest edge of said portion of the first partition-forming panel, which passes over said edge of the second partition-forming panel. In other form, said portion is hingeable to enable it to pass over said edge. Preferably each partition-forming panel has a notch or slot, the notches or slots co-operating with each other. Preferably the said edges of the two partition-forming panels have lead-in portions to the slots which are shaped to direct the partition-forming panels into the crosswise configuration.
- The invention also encompasses a blank of foldable sheet material for such a carton.
- Two preferred embodiments of the invention will now be described by way of example, with reference to the accompanying drawings, wherein:
- Fig.1 is a plan of a blank for forming a first carton,
- Fig. 2 shows the carton in a flattened condition prior to erection,
- Fig.3 is a view of part of the interior the carton during erection,.
- Fig.4 shows the erected carton,
- Fig.5 is a plan of a blank for forming a second carton,
- Fig.6 shows the second carton in a flatter. condition prior to erection,
- Fig.7 is a view of part of the interior of the second carton during erection, and
- Fig. 8 shows the second carton when erected
- Referring firstly to Fig.1, the blank for first carton is cut and scored from foldable board material and has four side wall-forming
panels panel 16 has atab 18 which, on forming the carton into the flattened condition shown Fig.2, is adhered to thepanel 10 at the other end of the row, so that the flattened carton of Fig.2 is essentially tubular. All thepanels panel 10 has a lid-formingpanel 20 hinged to one of its longer edges, thepanel 20 having a tuck-inflap 22 hinged to its edge opposite thepanel 10. Thepanels flaps 24 hinged to their longer edges on the same side as thelid 20. - On their longer edges opposite the
lid 20 andflaps 24, each of thepanels panel panels 28 hinged to the side wall-formingpanels panels 30. The bottom-formingpanels 26 are hinged at 40 to the side wall-formingpanels panels edge 32 of thepanel 26 tapers diagonally, and in the carton when erected thisedge 32 lies on a diagonal of one of the rectangular compartments. The opposite edge of thepanel 26 has aflap 34 connected thereto by ahinge line 36 which is at 45 to the hinge line between thepanels hinge line 36 is scored and perforated such that theflap 34 hinges downwardly from the panel 26 (that is, in the opposite sense to all the other hinge and fold lines of the blank). At the outer end of thehinge line 36, theedge 38 of thepanel 26 is nearly perpendicular to thehinge line 40. Theedge 38 extends as asmall cut 42 in the blank between theflap 34 andpanel 26, to meet thehinge line 36. - At its
edge 44 remote from thehinge 40, eachpanel 26 is hinged to a partition-formingpanel 46. Thepanel 46 has a laterally extendingportion 48, and anotch 50 is formed which partially divides theportion 48 from the rest of thepanel 46. Thenotch 50 extends from theedge 52 of theportion 48 which is closest to thehinge 40. Theedge 52 has a cam-shaped recess 54 which provides a lead-in to thenotch 50. - Each partition-forming
panel 30 has anotch 56 which co-operates with thenotch 50 when the carton is erected. Thepanel 30 has an upper edge which is cam-shaped at 58 to lead in to thenotch 56. Eachpanel 30 also has a C-shaped cut 60 leading into thepanel 30 from thehinge 62 between thepanels ledge 64 extending out of thepanel 28. There is also a line of weakening 66 extending at an angle between thenotch 56 and thecut 60 so that onehalf 68 of thepanel 30 can flex to a limited extent , with respect to theother half 70. - The blank is folded into the collapsed, flat carton of Fig.2 by folding the bottom-forming
panels panels flaps 34, folding thepanels 10 and 16 (with their associated paneis; over thepanels tab 18 or the inside of thepanel 10 and theflaps 34 to tha undersides of thepanels 28. - The flattened collapsed carton shown in Fig.2 can then be erected, for example by a macchine of the type disclosed in our German OLS No.2807968, The carton is erected by pushing the two
ends side walls panels flaps 34 which are hinged about their 450hinge lines panels 28, As thepanels panels recess 54 meets theupper edge 59 of thehalf 70 of thepanel 30. The cam shapes of therecess 54 andedge 59 guide the twonotches recess 54 follows thecam shape 58 of one partition-forming panel, theedge 38 causes thehalf 68 of the other partition-forming panel to flex. Obviously, if thehalves 70 flexed with thehalves 68 they would hinder the proper engagement of the partitions. It is for this reason that the lire or weakening 66 is provided so that thehalf 70 does not tend to flex with thehalf 68. - When the carton is completely erected, the
edge 38 of thepanel 26 rests on theledge 64 of thepanel 28. In addition, the ledge 64 slots into thecut 42 as thepanels panel notches - The erected carton thus has partitions defining six (i.e. 2 x 3) rectangular compartments into which goods can be packed. By suitable design of the blank, the compartments can be almost any rectangular shape, and for example could be square if desired. The carton could have a different number of compartments if desired; for example a carton with four compartments (2 x 2) could be made by providing only one each of the
panels partitions 46 are higher than thepartitions 30. This is not essential, though it is desirable that the depth of the panel 26 (measured from the hinge 40) is approximately the same as or greater than the corresponding depth of thepanels edge 52 passes over theedge 59 so that thenotches - Referring now to Figs. 5 to 8; the second carton works on the same principle as the first, and in the drawings similar parts have like reference numbers, although their dimensions may be a little different. The
flaps 24 have been separately identified as 24a and 24b. The major differences between the first carton and the second arise in the partition-forming panels. The second carton when erected has partiticns which form compartments which are more nearly square than in the carton of Figs. 1 to 4; in fact the compartments of the second carton are only a few millimetres out of square. - Instead of partition-forcing
panels 30, the bottom-formingpanels 28 have partition-formingpanels 72. Thepanels 72 have anupper edge 74 having anotch 76. Thenotch 76 is barb-like and has anabutment edge 78 and a lead-inedge 80. The lead-inedge 80 is cam-shaped, like the cam-shapededge 58 in Figs. 1 to 4 and functioning in a similar manner. Thecut 60 and line of weakening 66 of Figs. 1 to 4 are nor provided in the present embodiment. - The bottom-forming
panels 26 have partition-formingpanels 82 in place of the partition-formingpanels 46 of Figs. 1 to 4. Thesepanels 82 have laterally extendingportions 84, and theportions 84 are provided withflaps 86 which are hinged to theportions 84 abouthinge lines 88 which are generall, parallel to the hinge lines 40. Theflap 86 is on that side of theline 88 closest to the hinge line . Theflap 86 defines a notch or slot 90 with theadge 92 of thepanel 82. Theopposite edge 94 of thepanel 82 has a projectingportion 96. - The
flaps 86 have laterally extending tahs 98,100 respectively, the function of which will be described later. Thetab 100 is flexible in relation to itsflap 86, by reason of a line ofweakenign 10. These tabs 98,100 and their function are novel in themselves, and may have application in other carrcns than crash-bottom cartons. - The carton is erected from the blank of Fig.5 to the flattened condition shown in Fig.6 in the sand manner as before, the
flaps 34 being adhered to the bottom-formingpanels 28 as before. In addition, thetab 98 is flicked so that it lies on the other side of thepanel 24a. Similarly, thetab 100 lies behind che flap 24b, but there is no need for a special slicking operation to achieve this since thetab 100 will already be in place under the flap 24b when thetab 18 is adhered to the side wall-formingpanel 10. - The carton is erected from the flattened condition in the same way as the carton of Figs.l to 4. It will be appreciated that initially the tabs 98,100 are caught behind the
flaps 24a,24b as theside walls flap 86 catches behind the edge of thecorresponding panel 72, since otherwise the carton would tend not to erect properly. This is particularly true of thetab 98, since the correspondingpanel 72 necessarily has a cut out portion 104 (see Fig.5) corresponding to thetab 98. However, because thetab 100 occurs at the end of the blank there is no such cut out portion on theother panel 72. It follows that it is not strictly necessary for thetab 100 to be hooked behind the flap 24b, but it is easier to make the carton into the flattened condition of Fig.6 if this is so. The line of weakening 102 assists in disengaging thetab 100 from behind the flap 24b, this being more necessary than in the case of thetab 98 because of the presence of theadjacent lid panel 20. - It will be seen from Fig.6 that each
notch 76 is close to a corresponding projectingportion 96. As seen in Fig.7, when theside wall panels portoon 96 catches in itsnotch 76, and theabutment edge 78 bears against the projectingportion 96. This ensures that thepanel 82 is pushed so that theflap 86 hinges upwardly and passes over theopposite panel 72. Theflaps 86 are thus pushed over theupper edge 74 of thepanel 72, down the cam shapededge 80, and finally theflap 86 drops over thepanel 72 to lock the partitions in place in the configuration seen in Fig.8. In this erected configuration, the slot or notch 90 engages with thenotch 76, and because the partitions are locked the entire carton is strong and secure. - In use, cartons are supplied in the flat condition shown in Fig.2 or Fig.6 to the packer, who erects the carton (which only requires one stroke and can be done automatically by a machine such as that described in our German OLS No. 2807968). He then inserts the goods (e.g. glasses, which can go on their sides and are > therefore presented in a more attractive display) into the compartments. The
flaps flap 22 into the carton next tp theside wall 14. Where glasses are being packed, preferably the 5partitions

A crash-bottom carton according to any one of claims 6,7 or 8 characterised in that the portion (84,86) of the first partition-forming panel which passes over said edge (74) of the second partition-forming panel has a laterally projecting tab (98,100) which engages behind the second partition-forming panel during erection to ensure that said portion (84,86) passes over said edge (74).
10. A crash-bottom carton according to claim 9 characterised in that as the carton is erected from the flattened tubular condition, said tab (98,100) is first engaged behind a portion (24a, 24b) of the carton other than the partition-forming panels to cause it then to engage behind the second partition-forming panel.
11. A crash-bottom carton according to claim 10 characterised in that said tab (100) has a line of weakening (102) to enable it to disengage from behind said other portion (24a,24b) during erection.
12. A crash-bottom carton according to any one of the preceding claims characterised in that one of the bottom-forming panels (28) has a portion extending beyond the hinge line (62) with the corresponding partition-forming panel (30) to form a ledge (64), which ledge supports another of the bottom-forming panels (26) when the carton is in the erected condition.
13. A blank for forming a crash-bottom carton comprising an array of four wall panels hinged one to the next, means for joining the ends of the array together to form a flattenable tubular arrangement of the wall panels with two panels on one side and two panels on the opposite side of the flattened tube, bottom-forming panels being hinged to the wall panels and being attachable to each other so that when the wall panels are moved from the flattened configuration to the rectangular tubular configuration the bottom-forming panels automatically move into a co-planar configuration at the bottom of the erected carton, first and second said bottom-forming panels having hinged thereto respectively first and second partition-forming panels, characterised in that at least one of the partition-forming panels (30,46,72, 82) is shaped to provide a notch or slot (56,50,76,90) to receive the other crosswise on erection of the carton from the flattened condition, the first partition-forming, panel (46,82) having a portion (48,84,86) which on erection passes over that edge (59,74) of the second partition-forming panel which is remote from its bottom-forming panel (28) to bring the partition-forming panels into the crosswise configuration.
