The specific embodiment

Be noted that in the whole description and claims below that naming plate for " median plate " or " side plate " is in order to explain the accompanying drawing that is convenient for reference when of the present invention.Using this class term is not to be not intended to these plate added limitations yet.

Referring to Fig. 1 and 2, carton 10 is by

side plate

12,14,

end plate

13,15,16,18, and median plate 20 forms with base plate 22.Carton 10 is equipped with laterally but not belt handle 24 longitudinally.Belt handle 24 is oriented, and the user replaces between end plate 13/16 and 15/18 being able to catch this handle by hand in

side plate

12 and 14 extensions by finger is reached.As shown in the figure, carton 10 is equipped with 12 beverage bottle A, forms 12 packing in this example.In this embodiment, can or other products that is packaged in the carton is parallel to laterally being provided with of handle by its longitudinal axis.When mentioning by horizontal belt handle 24, the hoisting force that handle 24 is provided just direct into

side plate

12 and 14 rather than as traditional vertical belt handle be directed to median plate 20 or end plate 13/16 and 15/18 or the angle of carton on.The thickness that need not strengthen carton material so this hoisting force just is distributed on the broad zone holds load or prevents to tear.Many critical otch allow the hand that handle 24 is elevated to is enough to insert the user with folding, so that the user catches handle and lifts carton.

Fig. 2 shows the blank 26 that is used for forming carton 10.Blank 26 preferably forms with the from one piece that limits end plate and median plate by being provided with fold line 28 and 30.Median plate 20 comprises central median plate 20 and end.Similarly,

side plate

12 and 14 comprises central board and

end plate portion

13,15 and 16,18.Median plate 20 connects side plate 12 along fold line 32 and connects side plate 14 along fold line 34 simultaneously.Side plate 14 connects base plate 22a base plate 22b along fold line 36 and then connects side plate 12 along broken line 38.

Blank 26 is by the end plate cut of interrupted line of cut 40,42 along side plate and attachment, is able to remove material from these boards and forms the distributing box of can.Base plate 22 is comprising the score line that forms little set square 44,46.They are bent so that change otherwise will become the shape in square bight.Such bending provides the bight of topping of side plate 14.Base plate 22 also can comprise the score line that defines

removable plate

48 and 50.

Thereby plate 14 has the bight of topping gives this plate 14 octagon configurations.Blank all has otch in each bight of plate 14, but by be connected to

median plate

20 and 22 connecting panel along fold line the end of plate 14 and plate 20 is connected with 22 adjacent end portion, and is connected with the

end plate

16,18 of plate 14 by score line.So just can be when this carton of body plan that end plate is folding compactly.This octagon plate will suppose that the dihedral plate is more attractive in appearance pleasing, thereby can be used as Graphic Panel.It is not the space of always definite foursquare shelf that octagonal bight also often can compensate to a certain extent.

The master tape portion of belt handle 24 is defined between two otch in the median plate 20.

Handle fin

52,54 connects handle 24 along score line, with the thickness that increases band so that form more comfortable hand hole in the carton that causes assembling.Whole handle assemblies is passed median plate 20 and is extended on side plate 12 and 14.Like this, this handle assemblies is passed

fold line

32 and 34 extensions, and terminates in the plate 12 along fold line 56.The end of the middle body of fold line 56 bends towards plate 12.So just make fold line 56 be spill or fall " C " word configuration that the end of this " C " font ends at or the line of cut 58 and 60 of adjacent top and bottom.Line of cut 58 is tilted to down and extends then towards fold line 32 that on even keel advances to plate 20.Similarly, line of cut 60 be tilted to by plate 12 to fold line 32 then on even keel by plate 20.In order to prevent to tear and hoisting force is directly directed on the major part of

plate

20 and 22, line of

cut

58 and 60 end preferably are J-shaped, and the back of this J-shaped is relative mutually, so as the end of J-shaped in plate 12 mutually away from bending.Also can adopt the shape that differs from J-shaped, as long as this shape can be crooked in case tear and permission power is distributed on the major part of this plate away from the stressed zone.Line of

cut

58 and 60 preferably is not a complete line of cut but zigzag, so that carton assembles the back easily separately.

In the top of plate 20 hand hole otch and plate 20, have connecting panel 62 between the horizontal component of line of cut 58.Plate 62 is to be limited by orthogonal fold line and horizontal cut line.When along fold line when folding, the plane that main handle portion 24 can slave plate 20 upwards puts forward.So just can produce the space that allows hand to insert and promote carton.Similarly, the bottom along handle 24 can be with 64 folding connections of second connecting panel, with consistent with the operation of connecting panel 62.Plate 64 extends along the horizontal part of the line of cut in the plate 20 60.

Plate

14 and 20 is as one man operated around handle, forms the orthogonal fold line of guiding stress and the mirror image of line of cut.So orthogonal fold line 66 is the mirror image of orthogonal fold line 56, and be used for hoisting force is directed on the major part of plate 14 in case plate is torn when promoting carton.The top of orthogonal fold line 66 ends at or is adjacent to the top line of cut, and its bottom ends at or adjacent bottom line of cut 70.

Fold line

56,66 preferably can keep at a certain distance away with

relevant corner edge

32,34, so that when carton for example is equipped with the product A of can with shoulder B and so on, this part that can make that carton covers on the shoulder can meet the ramp shaped of shoulder when promoting carton.Because these characteristics, can or other goods with shoulder just can not hinder stress to be folded the mode of line 55,56 guidings.Line of cut 68 is mirror images of line of cut 58, and line of cut 70 is mirror images of line of cut 60.The top connecting panel 72 that is associated with line of cut 68 is mirror images of connecting panel 62, and the connecting panel 74 that is associated with line of cut 70 then is the mirror image of connecting panel 64.When blank 26 was assembled into carton, the hoisting force that handle 24 produces just also distributed by base plate 22 along

plate

12 and 14.

Median plate 20 also comprises similar and play the

set square

76 and 78 of similar functions with set square 44 and 46.In addition, these set squares the time have compensated the can of distortion or to the damage of carton in delivery to a certain extent.They have considered that carton slightly expands or swells and the globality of structural damage not.In addition, during along crosswise fixed, this hoisting force just directs into any otch, fold line, angle or the thin spot place that does not directly point to carton in most of paper material with handle.This hoisting force is directed to and makes their cloth scatter to provide required intensity so that carried and do not rely on special architectural feature by most of material.

Referring to Fig. 3, wherein show another embodiment of horizontal belt handle with the blank form that forms carton.

Fig. 3 illustrates the blank 126 that can form the carton that is similar to carton 210 shown in Figure 4.Blank 126 is similar to above-mentioned blank 26 and will be in the blank of discussing later 226.Blank 26 has formed the carton that can adorn goods (can) A 12 Packing Units, these goods A is parallel to handle band 24 and is provided with, blank 126 then forms the carton of 6 Packing Units, and goods wherein such as can are arranged in the packing chest of blank 126 formation, the top of goods or base abuts median plate 120.Blank 126 is divided into end plate and median plate by fold line 128 and 130.Median plate 120 is divided into median plate 120 and end 116 and 118 by fold line 128,130.Side plate 112 and 114 are divided into central board and end plate portion.Median plate 120 is connected also with side plate 112 along fold line 132 and is connected with side plate 114 along fold line 134.Base plate 122a is connected with side plate 112 along fold line 138 and is connected with base plate fin 122b along fold line 136 simultaneously.

The score line of the little set square 144,146 of the formation that side plate 122 includes, these little set square bendings are to change the shape that not so will become accurate square angle.Similarly, side plate 112 includes the score line that forms little set square 176 and 178.

Plate 120 has the bight of topping so that provide the octagon configuration.Each angle at plate 120 in this blank has otch, and the end of palette 120 then by being connected with 122 adjacent end portion along fold line and plate 112 and 114 bonded assembly connecting panels and plate 120, is connected with the end plate 116,118 of plate 120 by score line simultaneously.

Laterally the master tape portion of handle band 124 is defined between two otch in the median plate 120.Handle fin 152,154 connects handle 124 collapsibly along score line, increasing the thickness of band, thereby forms more comfortable hand hole in the carton that assembles.Whole handle assemblies extend through median plate 120 is on side plate 112 and 114.Like this, this handle assemblies is passed fold line 132 and 134 extensions, and ends at plate 112 places along fold line 156.The end of the vertical middle body of fold line 156 bends towards side plate 112.So just make fold line 156 be spill or fall " C " word configuration that the end of " C " font ends at or the line of cut 158 and 160 of adjacent top and bottom.Line of cut 158 is tilted to down and extends then towards fold line 132 that on even keel advances to plate 120.Similarly, line of cut 160 be tilted to by plate 112 to fold line 132 then on even keel by plate 120.In order to prevent to tear and hoisting force is directly directed on most of material of plate 112, line of cut 158 and 160 end preferably are J-shaped, the back of this J-shaped mutually relatively in case the J-shaped end on plate 112 mutually away from bending.

In the top of plate 120 hand hole otch and plate 120, have connecting panel 162 between the horizontal component of line of cut 158.Plate 162 is limited by orthogonal fold line and horizontal cut line.When along fold line when folding, the plane that main handle portion 124 can slave plate 120 upwards puts forward.Promote carton with regard to producing the space that can allow hand to insert like this.Similarly, second connecting panel 164 can be connected collapsibly along the bottom of handle 124, with consistent with the operation of connecting panel 162.Plate 164 extends along the horizontal part of the line of cut in the plate 120 160.

Plate 112 and 114 is as one man operated around handle, forms the orthogonal fold line of guiding stress and the mirror image of line of cut.So orthogonal fold line 166 is the mirror image of orthogonal fold line 156, and be used for hoisting force is directed on most of material of plate 114, in case plate is torn when promoting carton.The top of fold line 166 ends at or is adjacent to top line of cut 168 and its bottom ends at or adjacent bottom line of cut 170.Line of cut 168 is mirror images of line of cut 158, and line of cut 170 is mirror images of line of cut 160.The top connecting panel 172 relevant with line of cut 168 is mirror images of connecting panel 162, and the connecting panel 174 relevant with line of cut 170 then is the mirror image of connecting panel 164.When blank 126 was assembled into carton, the hoisting force that handle 124 produced just distributed and by base plate 122 and no-go end plate 116,118 along plate 112 and 114.

Along crosswise fixed, this hoisting force is directed in most of material and does not directly point to any otch, fold line, angle or the thin spot place of carton with handle.This hoisting force is directed to and makes them be distributed, and is carried by most of material and the special architectural feature that do not rely on such as the bight provides required intensity.

Referring to Fig. 4, in its shown horizontal handle assemblies, handle band 224 is formed among the median plate part of the median plate 214 that is orientated carton 210 in the carton that assembles rather than this carton.As mentioned above, the plate of plate being named for " side plate " or " median plate " or other titles is for the ease of discussing rather than be used for limiting irrelevantly the present invention.The orientation of carton 210 shown in Figure 4 is according to the location situation of the assigned characteristics shown in Fig. 5 blank.Fig. 5 illustrates the blank 226 that is used for forming carton 210.Blank 226 is preferably formed by from one piece, is divided into end plate and median plate by fold line 228 and 230.Side plate 220 is divided into side plate 220 and end 216 and 218.Base plate 212 is divided into central board and end plate portion with 214 of median plates.Median plate 120 is connected with base plate 212 along fold line 232, is connected with median plate 214 along fold line 234 simultaneously.Median plate 214 connects side plate 222a along broken line 236, and side plate 222b is connected with base plate 212 along orthogonal fold line 238.

Laterally handle band 224 has the master tape portion that is defined between 214 liang of otch of side plate.Handle fin 252,254 is connected with handle 224 to strengthen the thickness of this band, for use in form more comfortable hand hole in the carton that assembles along score line.Whole handle assemblies is passed side plate 214 and is stretched on side plate 220 and the base plate 222.So

passing fold line

234 and 236, this handle assemblies extends.This handle assemblies ends on the side plate 220 along the fold line 256 that ends at or approach top and bottom line of cut 258 and 260.Line of cut 258 by side plate 220 along horizontal-extending to fold line 234, on even keel arrives plate 224 then.Line of cut 259 starts from the termination of line of cut 258 and continues on even keel towards main handle portion, but is positioned than line of cut 258 more contiguous handles, forms a discontinuities between line of cut 258 and 259.Similarly, towards fold line 234, on even keel extends on the median plate 214 line of cut 260 then along level process side plate 220.Line of cut 261 starts from the termination of line of cut 260, continues on even keel towards main handle portion but be positioned than line of cut 260 more near this handle place formation one discontinuities between line of cut 260 and 261.In order to prevent to tear and hoisting force is further imported on the major part of side plate 220 and 222, line of

cut

258 and 260 end be J-shaped preferably, the back of this J-shaped relatively so that the end of this J-shaped mutually away from bending.

Have a connecting panel 262 between line of

cut

258 and 259, the connecting panel 263 that links to each other extends between line of cut 259 and the top hand hole otch in median plate 214.

Plate

262 and 263 is to be limited by orthogonal fold line and horizontal cut line.Along fold line when folding, main handle part 224 can upwards put forward from the plane of this median plate 214.Produced like this and inserted the space of hand so that mention this carton.Similarly, along the base section of handle 224, connecting panel 264 is connected with 265 collapsibly so that as one man operate with connecting panel 262 and 263.Connecting panel 264 exists between line of

cut

260 and 261, extends between the bottom hand hole otch of plate 265 in line of cut 261 and median plate 214 that links to each other.

Median plate 214 and side plate 220 are as one man operated around handle, form the orthogonal fold line of guiding stress and the mirror image of line of cut.So orthogonal fold line 266 is the mirror image of orthogonal fold line 256, and be used for hoisting force is directed on the major part of plate 222 in case plate is torn when promoting carton.The top of orthogonal fold line 266 ends at or is adjacent to top line of cut 268 and its bottom ends at or adjacent bottom line of cut 270.Situation as fold line in above-mentioned Fig. 1 and 2 56,66, fold line 256 preferably can be opened certain distance in 234,236 minutes with relevant corner edge with 266, so that the product A of can with shoulder B and so on for example to be housed at carton, this part that can make that carton covers on the shoulder can meet the ramp shaped of shoulder when promoting carton.Because these characteristics, can or other goods with shoulder just can not hinder stress to be folded the mode of line 256,266 guidings.Line of cut 268 is mirror images of line of cut 258, and line of cut 269 is mirror images of line of cut 259, and line of cut 270 is mirror images of line of cut 260, and line of cut 271 is mirror images of line of cut 261.The top connecting panel 272 that is associated with line of cut 268 is mirror images of connecting panel 262 and connecting panel 273 is mirror images of connecting panel 263, and the connecting panel 274 that is associated with line of cut 270 is mirror images of connecting panel 264, and connecting panel 275 then is the mirror image of connecting panel 265.When blank 226 combined carton, the hoisting force that handle 224 produces just distributed along side plate 220 and 222.

Referring to Fig. 6, wherein show the another kind of blank 326 of the horizontal belt handle carton of 12 bottle packing amounts.Handle is similar shown in the blank of this horizontal belt handle and Fig. 2 and 5, except orthogonal fold line is straight.Laterally the master tape portion of handle band 324 determines in median plate 320 between two otch.Handle fin 352,354 is connected with handle 324 along line.Whole handle assemblies extend through median plate 320 on

side plate

312 and 314, thereby extends through broken line 332 and 334.This handle assemblies ends on the side plate 312 along fold line 356 and ends at side plate 314 places along fold line 366 simultaneously.Fold line 366 ends at or adjacent top and bottom line of cut 358 and 360.Fold line 356 preferably separates certain distance with relevant corner edge with 366, with the based article of bottle of this carton carrier tape shoulder of box lunch (in the bottle situation, this shoulder is lower than the shoulder of can) time, the part of this shoulder of covering of carton can meet the slope of this kind shoulder when carton is raised.Because these characteristics have the bottle of shoulder or other goods just can not hinder the mode that is folded line 356,366 guiding stress.Line of cut 358 is tilted to down the distance of extending one section weak point towards fold line 332, enters on the plate 320 along horizontal line then.Similarly, 360 of lines of cut are tilted to the distance of extending one section weak point by plate 312 towards orthogonal fold line 332, and on even keel is by plate 320 then.Line of

cut

358 and 360 end preferably are J-shaped, so that the back of J-shaped in opposite directions and the end is remotely crooked mutually in plate 312.

In the top of plate 320 hand hole otch and plate 320, have connecting panel 362 between the horizontal component of line of cut 358.Plate 362 is limited by orthogonal fold line and horizontal cut line.When along fold line when folding, handle 324 can upwards put forward from the plane of median plate 320.So just can produce the space that allows hand to insert and promote carton.Similarly, the bottom along handle can be with 364 folding connections of second connecting panel, with consistent with the operation of connecting panel 362.Plate 364 extends along the horizontal part of the line of cut in the plate 320 360.

Plate

314 and 320 forms the orthogonal fold line of guiding stress and the mirror image of line of cut around the handle coherency operation.So orthogonal fold line 366 is the mirror image of orthogonal fold line 356.The top of orthogonal fold line 366 ends at or is adjacent to top line of cut 368, and its bottom ends at or adjacent bottom line of cut 370.Line of cut 368 axis of pitch by this handle and line of cut 358 be mirror image each other, and simultaneously by longitudinal axis and line of cut 370 mirror image each other, line of cut 370 then and line of cut 360 mirror image each other.With the relevant top connecting panel 372 of line of cut 368 and connecting panel 362 mirror image each other; And the connecting panel 374 that links to each other with line of cut 370 and connecting panel 364 mirror image each other.When blank 326 is assembled into carton, the power that produces when promoting by handle is just along
