Description

The box that cuts sheet and made by it is especially for the box of cigarette

Technical field

The box that the present invention relates to cut sheet and made by its is used as the packing of cigarette especially as it.

Background technology

Cigarette usually or in rigid pack or in soft box packing, for example in renovating box or in hinge-lid-box, but also so-called rigid-soft-be not with in packing to be devoted on the market with renovating.Also known under the situation of rigid pack, with angle and rib rounding, protect customer's pocket with this.For example DE29 40 797A1 describe hinge-cigarette cases such as lid-type for this purpose like this, and all angles and rib all are slick and sly.Yet the open text of this Germany is not announced how to make this box.

A kind of hinge-lid-type cigarette case has been described, its four level master rib chamferings or rounding in EP0 764 595A1.Also illustrated and cut sheet accordingly in order to make this rib.Ou Zhou open text comprises citation to US2 523 251 (51 to 54 row in EP0 764 595A1 the 4th hurdle) and also comprises the rounding of horizontal rib of EP0 764 595A1 thus and the chamfering of the long rib of chamfering and US2 523 251 makes up in addition.But also lack indication, how to make this special form of implementation.

In fact make box by the independent sheet that cuts, the particularly wherein all angles and the main rib of long rib and level all the cigarette of rounding or chamfering to fold hamper be inconvenient.

Summary of the invention

Therefore the objective of the invention is, the scraps of paper of preparing to make easily that cut are used to make box, the particularly wherein all long ribs and the main rib of level and angle all as much as possible the cigarette of rounding or chamfering fold hamper.

The box of at least 5 face closures that are used to form rectangular parallelepiped shape that the solution of this task is made by Foldable material cut sheet, wherein the just in time relative interarea zone of two formation rectangular parallelepiped is connected the base surface area in interarea zone with one, cutting arrangement one by one point-blank on the sheet, in rectangular parallelepiped shape box to be formed with two just in time relative interarea zones and with each face of bonded assembly bottom surface district, interarea zone adjacency, form by side regions, stretch out on the next door in two interarea zones the side, and the rib in two just in time relative interarea zones in rectangular parallelepiped box to be formed each form by the fold domain.

It is characterized in that,

-two fold domains can be combined in (preferably down) corner in two just in time relative interarea zones in rectangular parallelepiped box to be formed mutually; And

In-the fold domain of joining mutually two (preferably basic right angle), one by about 45 ° to 90 °, best 65 ° to 80 ° arc section, and another constitutes the border by the S-curve, S-curve towards the angle in interarea zone near arc section; And

Preferably respectively by two or many vicinities, substantially parallel fold line forms in-each fold domain.

The sheet that cuts that comprises the first interarea zone of di sopra explanation preferably, the first interarea zone has a left side and right first side regions; Wherein

-base surface area is connected on the last rib in the first interarea zone, and the second interarea zone that has a left side and right second side regions is connected on the last rib of base surface area;

-the scraps of paper that cut have level and vertical folding zone, promptly between the first interarea zone and the base surface area and the base surface area and the second interarea zone between the first and second horizontal folding zones, between between on the left side first side regions and the first interarea zone, between the first interarea zone and first side regions of the right, the left side second side regions and the second interarea zone and the second interarea zone and the right second side regions between first to fourth vertical folding zone;

-the first horizontal folding zone is angle and the junction mutually of first and second vertical foldings zone on the first interarea zone; And

Join mutually in the inferior horn and third and fourth vertical folding zone in the second interarea zone in-the second horizontal folding zone.

The above-mentioned sheet that cuts can be with simple mode by being used to make the machine that cuts sheet and changing accordingly and make existing.Produce rigid pack by common folding and bonding by cutting sheet, this rigid pack only is made up of a cassette portion, can wrap into one group of cigarette within it within the line.Usually, the size of box is determined like this, be contained in the box, and the end of opening on top is outstanding slightly one group of cigarette consolidation, makes the customer can open cigarette case and takes out cigarette.

But box generally speaking also has a lid part except that the box part, so that produce hinge-lid-box.

In order to obtain popular hinge-lid-box, the above-mentioned sheet that cuts has an additional zone, the 3rd interarea zone that promptly has a left side and right the 3rd side regions with second interarea zone bonded assembly, one of them upper zone is connected on the last rib in the 3rd interarea zone, and the 4th an interarea zone that has a left side and right flank zone is connected on the last rib of upper zone; And

-cut sheet and also have other level and vertical folding zone, promptly between the 3rd interarea zone and the upper zone and the third and fourth horizontal folding zone between zone and the 4th interarea zone in the above, between between on the left side the 3rd side regions and the 3rd interarea zone, between the 3rd interarea zone and the right the 3rd side regions, the left side the 4th side regions and the 4th interarea zone and the 4th interarea zone and the right the 4th side regions between the 5th to the 8th vertical folding zone;

-Di three horizontal folding zones on the 3rd interarea zone the angle and the 5th and the straight fold domain of sextuple join mutually; And

Join mutually in the inferior horn and the 7th and the 8th vertical folding zone in the 4th interarea zone in-Di four horizontal folding zones.

Advantageously cut sheet also have except that above-mentioned zone is replenish the left side of a left side and the right second side regions inferior horn and the right second side regions sheet and on a left side and right the 3rd side regions the left and right side the 3rd side regions sheet at angle.These side regions sheets are used to the bottom surface and the lid of the box strengthening finishing.

Being preferably on the last rib in the 4th interarea zone has a reinforced region, and this reinforced region sticks on the inboard of the 4th interarea and plays booster action simultaneously when making box.

As Foldable material, common material can be used to make hinge-lid-box, for example paper or cardboard, and the words that need are carried out coating, and plastics, plastic sheeting or laminated plastic, preferably wide cut-paper or wide cut-cardboard.

Fold line can or groove, perhaps score line preferably, and be preferably on whole length of box and the width and extend.

In order to make groove, the relevant position that cuts sheet is pressed into by the indent body.At corresponding surface the raceway groove of grooving is arranged, the material that cuts sheet can be pressed into wherein.When groove extends in parallel, produce corrugated cross-sectional plane corresponding to said method.This method for example had been described among the US2 523 251, and its result is drawn among Fig. 2.By the finished like this sheet that cuts when folding, then form the rib of packing box (when a plurality of groove) circle or (at two grooves time) chamfering automatically along groove.

But at this disadvantage is arranged also, because the intrinsic rigidity and the screen resilience of packing, the bonding that is used to make packing box is not no problem.This usually occurs in the overlapping region that cuts sheet that forms cassette sidewall.By with rib rounding or chamfering, compare the overlapping region with common for example hinge-lid-box and obviously reduce, can only smear limited amount glue like this.Therefore consequence is, machinery production is slowed down, and is dry well up to the glue of relatively small amount because must wait for for a long time, otherwise the screen resilience of box by material is opened again.

If use wide cut-cardboard or wide cut-paper manufacturing, hinge-lid-box product for example, this problem is outstanding especially.The material that forms product when making paper or cardboard is placed on being with of rapid motion.This causes the long fibre in the material preferably longitudinally to locate.According to cutting sheet is that the long fibre in cutting sheet is arranged transverse to the longitudinal axis that cuts sheet (wide cut) or longitudinally to the longitudinal axis that cuts sheet (in a narrow margin) from vertically or laterally the downcutting of the material web finished.The orientation of fiber vertically causes around the good bending property of transverse axis transverse to wide cut-cut sheet, but around the bad bending property of the longitudinal axis.The bonded assembly screen resilience in side therefore than in a narrow margin-to cut sheet strong, in a narrow margin-cut in the sheet owing to the long fibre conversion in the material position, performance is opposite fully.Preferably use wide cut-cut sheet for folding boxes but then, because the stability of the lid (sealing of can not tilting, lid is not easy to be torn), the rigidity of packing box is passed through in horizontal advantages of higher stability, the straight and even state of packing box, possible small the arching upward of packing box just, wide cut-cut sheet and use in a narrow margin-material is compared all obviously favourable.

By using score line, opposite screen resilience with groove unexpectedly reduces significantly, makes wide cut-material energy be used to make box no problemly and promptly, can be because of going wrong when boning box for the face that uses is too little.

In order to make score line reduces the material that constitutes packing box with scarifying knife thickness.Be placed on usefulness slide mark cutter processing on the level and smooth base for this cuts sheet, make and except that compression, also can remove material.Produce the cross-sectional plane of V-for example or U-shape according to the shape of slide mark cutter.Because base is unlike in the raceway groove that has in the method for making groove on the opposite of scarifying knife, but level and smooth surface reduces thickness, unlike need not to reduce thickness in order to form groove.

The degree that thickness reduces depends on employed material and relevant fold domain.The score line in vertical folding zone is by 10-80%'s, best 30-70%'s, particularly preferably be 40-60%'s, for example about 50% the paper or the thickness of cardboard reduce to form, the score line in horizontal folding zone is by 10-50%'s, best 20-40%, the reducing of for example about 30% paper or cal(l)iper forms.

Score line is also owing to for being had a preference for according to second reason that cuts sheet of the present invention.Be that score line has following advantage, it is in the inboard of the packing box of finishing, and the outside is intact and looks like undressed mistake that therefore for the customer provides a visual appearance preferably, this is impossible fully when using groove.

Number and their mutual spacings by score line can be determined round size and form.Preferably each fold domain has 6 to 8,7 fold lines particularly, and their mutual spacings approximately are 1mm.Produce the box with rounding rib so when folding, radius of a circle is approximately suitable with the cigarette of selling usually.Each fold domain also can preferably be selected two fold lines for use, and their spacing is 6 to 8 millimeters, particularly 7 millimeters.When folding, produce the box of rib so with chamfering.

In order to make box that the visual appearance of a unanimity be arranged, preferably also will all fold domains has the fold line of similar number.

Vertically can lump together in order to make with fold domain level, preferably the end of the end of arc section and S-curve is in the right angle stretching, extension, and parallel with the rib in interarea zone, because in this way can the transition of no problem ground between different fold domains.

Best arc section and the S-curve does not interconnect or only interconnect at the angle point place in interarea zone.Although the connection to small part may be arranged between arc section and S curve in principle, when then being folded to form box, in the transitional region between these two different fold domains extruding and irregular can appear together.

Also will be preferably, at least one fold domain at both ends or define by arc section or by the S-curve, equally preferably, in all two ends meet at right angles the fold domain of meeting with other fold domain substantially, the two ends of this fold domain or by arc section or desire the S-curve and define.At last also preferably, finish separately or with arc section or with the S-curve all fold domains that are parallel to each other.All produce eye impressions preferably at all under these three kinds of situations.

Make in a known manner and cut sheet.That is to say to cut sheet, preferably become wide cut-cut sheet from being stored in cutting on the sheet material web down and printing on the roller by volume.This is one procedure normally, handles cutting sheet therein with scarifying knife or the above-mentioned mode of indent body and function, and punching press simultaneously and/or cut off and impression when needed.By common folding and be bonded at and just mechanically obtained manufactured product on the side, cigarette case for example, it contains one group of cigarette of wrapping up within the line within it usually.Usually also use flange portion commonly used in according to hinge of the present invention-lid-box, flange portion is side-prominent and a groove is arranged in the box fwd slightly in the box of opening, and this groove makes it possible to catch the cigarette in the cigarette case.
