Abstract

Pouches with easy-tear lines of weakness may be faced with difficult tear-initiation and un-controlled tear-propagation. Pouches formed on FFS machines may have mis-aligned lines of weakness as the film is known to shift on the machines. The tear initiation notches may also be mis-aligned with weakened lines. It has been determined that this problem may be solved by having a plurality of at least partly non-linear weakened lines where at least two of the weakened lines converge into a single line. This feature allows for controlled and guided tear-propagation so that a portion of the pouch may be removed easily. Disclosed is a pouch with a continuous edge or plurality of edges, the pouch having plurality of weakened lines starting from the continuous edge or from one of the edges; wherein the plurality of weakened lines are at least partly non-linear and at least two lines converge to form a single weakened line.

Description

Pouch with laser scratch
Technical field
The present invention relates to a kind of pouch for packing, relate more specifically to have line of weakness so that the pouch that pouch can easily be opened.
The present invention is developed to and is mainly used in disincrustant, and will after this describe with reference to this should being used for.Yet, should be understood that, the present invention will be not limited to the use of this specific area.
Background technology
Should not be considered to admit this prior art well-known to any discussion of prior art in this manual or form under the part of public general knowledge in field.
Flexible pouch (also becoming pouch or bag) is used for packing various products.Most of pouches are filled sealing (FFS) machine in moulding and are made and fill.Pouch is made by the film that intensity can resist any damage of transportation, storage and operating period.
Need to open pouch and empty contents.Yet some pouch is difficult to open, because sealing is very strong, perhaps because plastic film is tough and tensile.When pouch or hand are moistening, may more difficultly open.For example, it is very difficult opening the shampoo pouch with wet hand.Usually need pocket knife or scissors.Yet, may not be to obtain at any time pocket knife or scissors.In the situation that there are not them, the user may attempt opening by force pouch.Usually, the inhomogeneous and described pouch of this power is split or contents overflow.This causes easily tearing the development of pouch.
Easily tear pouch and made by the superfine plastics of easily tearing, perhaps they have for what help to tear and tear breach or line of weakness.
Pouch with reduction tear line is known.Laser is widely used in the formation line of weakness, but other modes that weaken such as machinery also are known.
Preferably, in the situation with the pouch of laser scratch line of weakness of line of weakness-especially, it is easy beginning to tear and tearing conduction.Tearing conduction also should be ideally towards the side of pouch, so that the part (normally bight) of the described pouch of can easily tearing.The shortcoming of some laser scratch pouch is to be difficult to begin to tear and to tear conduction uncontrolled.Sometimes, tear in the body that conducts to pouch, but not towards the side of pouch.
US5158499A makes the trial that addresses this problem in (American Can Company, 1992).This application discloses and has approached or a plurality of linearities of contiguous sealing or straight continuous laser score line substantially, and described line extends and crosses the whole width of pouch.We determined linear tear line can not always provide controlled and guided tear conduction.When opening pouch along linear line of weakness, tear to conduct to exceed and limit the path and enter the body of pouch.We also determined the linear laser score line need to weaken-for example the laser scratch in this application becomes the obvious degree of depth.This needs higher laser power and expends more electricity.
WO2009/110398A1 (Hosokawa Yoko Co., Ltd) discloses a kind of for a large amount of contents of easily primary emission and the bag that more easily grasps in use.This application discloses a kind of bag with bag body, and described bag body has the first and second sides and the 3rd side that intersects each other, and described the 3rd side rolls with respect to described first and second tiltedly extends and the restriction opening.The ejection element connection protrudes to the bag body and from the 3rd side.Described ejection unit comprises the slide fastener that is positioned at bag body interior.Described bag body also can comprise the tear portion with the 3rd side superimposed that tilts.Described tear portion can be by the rough surface formation that layer attenuation is formed or it can be gathered by having minute aperture.The U-shaped recessed portion is positioned to away from slide fastener, and forms at least one of the first and second sides that are used for grasping described bag.The document does not have the line of weakness of an open part for tearing bag.
US2010/0226598A1 (Stoeppelmann) discloses pouch, and described pouch has for 3 linear tear lines tearing conduction controlled and that guided.Described 3 line of weakness are spaced apart from each other.Medium line is short more a lot of than other 2 lines.Described medium line is provided with tears the beginning breach.The width of pouch is crossed in described other 2 lines extensions.In use, the user can begin to tear at the medium line place and when the user tears described medium line fully, and any excessive power makes tear line move on to described first or move on to the described second outer line of weakness from described point.Tearing outside described 2 in the line of weakness which bar in the middle of leave after the line of weakness conducts and depends on the direction that acts on tear edge.Therefore, described medium line begins to tear, and conduction is torn in simultaneously outer line of weakness control and guiding.
We are definite, and packaging film has experienced the visibility point change when automatic moulding is filled in the sealer when the online moulding of pouch.The line of weakness that this position changes on the header board that does not always allow pouch is alignd with the corresponding line of weakness on the rear plate.In addition, this position changes and does not always allow to tear the beginning breach and aim at predetermined line of weakness.
If described line is not aimed at, if perhaps the described beginning breach of tearing is not aimed at line of weakness, the purpose of so easily tearing may not can realize.This problem can solve by darker line of weakness, but this may increase cost.Under the effect of the stress that applies when filling the sealer running in moulding, the mechanical strength of the pouch that obtains by punching press will reduce.
Therefore, need a kind of pouch, described pouch can easily begin to tear and tear with larger control and accuracy conduction; Even when forming at the FFS machine and filling described pouch and film also is like this when having a certain amount of position to change.
We have determined can address this problem when in many at least part of non-linear line of weakness and the described line of weakness at least 2 are converged to single line when pouch has.The feature of many non-linear line of weakness of part is convenient to the aliging and begin and tear of corresponding line of weakness on line of weakness and the rear plate on the header board.The feature that in the line of weakness at least 2 are converged to single line allow controlled and guided tear conduction so that the part of described pouch can easily remove.
Summary of the invention
According to first aspect, a kind of pouch with continuous boundary or a plurality of edges is disclosed, described pouch has from many line of weakness of described continuous boundary or a beginning from described a plurality of edges; Thereby wherein said many line of weakness are at least part of nonlinear and at least 2 lines convergence formation single line of weakness.
According to second aspect, the use of the pouch of the first aspect that is used for packing family and personal care product or food is disclosed.
As used herein, term " line of weakness " and " score line " mean to cut fully one or more layers of the film that is used to form pouch, perhaps mean the reduction that the described layer of permission of this layer is cut off along score line.
Describe in detail
In one aspect, disclose a kind of pouch with continuous boundary or a plurality of edges, described pouch has from many line of weakness of described continuous boundary or a beginning from described a plurality of edges; Thereby wherein said many line of weakness are at least part of nonlinear and at least 2 lines convergence formation single line of weakness.
Preferably, described single line of weakness is extended the starting point of leaving described many line of weakness towards described continuous boundary, same edge or neighboring edge.
Many line of weakness
Although described pouch can easily be torn when forming single line of weakness when at least 2 in described many line of weakness convergences; But preferably, from institute's wired all can gathering and form single line of weakness of described continuous boundary or a beginning from described a plurality of edges.This can further improve tears beginning and especially tears conduction, so that the part of described pouch (preferably certain part at edge) can more easily be torn.
Described single line of weakness can be extended towards described continuous boundary, same edge or neighboring edge.In this case, can be directed and control by described single line of weakness because tear conduction, most of pouches can easily be torn.
After easily having torn the overwhelming majority of pouch, can tear remainder by applying certain power, if perhaps opening is enough to easily the access contents and also can stays on the described pouch.If weakening part is torn in expectation fully and so that further reducing effect power and by providing the easier conduction of tearing to the better control of tearing; Preferably, described single line of weakness extends to described continuous boundary, same edge or described neighboring edge.
Although described many line of weakness are at least part of nonlinear; But preferably, every in described many line of weakness is crooked.When comparing with the non-linear profile of other types, this just provides and has better torn conduction control.The radius of curvature of line when their are crooked depends on the size of described pouch/bag.Preferably, every radius of curvature in the described wiggle all at 10mm between the 150mm.
Described single line of weakness can be linear, but preferably crooked.When bending, the radius of curvature of described single line of weakness depends on the size of described pouch/bag.Preferably, the radius of curvature of described single line of weakness at 10mm between the 150mm.
Preferred pouch has at least 3 line of weakness.In this case, further preferably, described second linear distance described first and described the 3rd line are equidistant, until described line is assembled.
The method of reduction
Can produce line of weakness with following method, include but not limited to: cut, perforation, chemical treatment, the preferably combination of laser scratch, laser beam perforation, mechanical mark, machine drilling, method for stamping or these methods.
Described line of weakness preferably formed in described film before film forms pouch, but alternatively, and not so preferably, can not be during the pouch manufacturing or afterwards by be attached to moulding fill sealer the cut device-for example the laser scratch device is introduced described line of weakness.In a preferred method, the material of described pouch weakens in specific location.
This can align with the figure on the material, so that when filling the described material of sealer processing in moulding, described line of weakness appears at the desired locations place.Manufacturing has line of weakness so that the technical personnel in the field of the pouch of opening will be known position how to handle these line of weakness.
Particularly preferably be, every in the line of weakness all is laser scratch, and so line can more easily be torn and they provide tearing beginning and tearing better control and the accuracy of conduction.
In order to use laser, have enough wattages so that the laser beam of the part of evaporating film focuses on the described film.The use of laser technology allows to penetrate into described film complete perforated to the control of the degree of depth or from very trickle cut.Optical maser wavelength can be about 0.2 to the scope of about 40 μ m.
Described laser beam can monotype structure or the use of multi-mode structure.Further, described bundle can be pulse or continuous.Can adopt pulsed beams to form interrupted or discontinuous cut, but when expectation acquisition continuous easily open line of weakness the time preferably use continuous bundle.
Laser output power can have any wattage.For example when sending many bundles, preferably uses expectation laser high wattage.Therefore, laser power can be in up to 500 watts scope, in order to use when for example allowing 5 100 watts bundles or 10 50 watts of bundles.
Can be by any known manner-produce many bundles by the partial reflector beam splitting.Usually, the beam power of use can change according to multiple-structure or processed film or the thickness of lamination and the relative motion between described bundle and the described workpiece.Can use the arbitrary arrangement combination of described bundle.
Alternatives as laser can be used blade.Described blade is installed on the engraving post, and described engraving post is directly installed on the film handling machine in order to finished cutting before forming described pouch.
Can obtain with different blade patterns the line of weakness of different patterns.The pressure that is applied to blade also changes during processing, thereby easily opens so that the size of control cutting and the degree of depth are guaranteed bag.
Impression is another alternatives for line of weakness.Stamping technique comes weakened film in the specific region by pressure, temperature, time and deformable contour.Expected result is to realize by the survey meter and/or the material structure that change impression track place.The infrastructure device that is used for impression comprises the jaw that can push against rear plate.Deformable contour or pattern are fixed to described pawl and are heated.Described film is squeezed between described deformable contour and the described rear plate.Film tension force, rear plate material, rear plate thickness, rear plate temperature, pawl pattern and pawl thickness behind film tension force when the variable of this process of known effect is heating-up temperature, chilling temperature, pressure, time of heat, hardening time, impression, the impression.
Described film can also come mechanical reduction by light punching, light cutting or light punching press.
Described line of weakness can have pattern.Those patterns can be taked the form of continuous lines, dashed line or their combination.Yet most preferred pattern is dashed line, and wherein said dashed line is formed by a plurality of cut sections.The length of every cut section can followingly change: between from 0.12mm to 4.4mm, preferably from 0.3mm to 2mm between, and between most preferably from 0.6mm to 1mm.Distance between the adjacent cut section can followingly change: from 0.4mm to 4mm, and preferably from about 1mm to 3mm, and between most preferably from 1.5mm to 2mm.Scratch depth will according to thickness and the film of film characteristic-especially its intensity changes.The Length Ratio that can have cut section and non-cut section along every line of weakness.This ratio preferably from 1 to 2.In other words, the cut section will be half of length of the non-cut section in centre between each cut part.
Most preferably, get the laser scratch line ready and be made for the laser power with 200 watts of minimums, thereby speed is controlled to 5mm/s and be controlled at 60 μ s pulse widths.
Although can one or more setting in described many line of weakness tear the beginning breach; But alternatively and more preferably, one in described continuous boundary or the described a plurality of edge is jagged.Need to go out from the pouch that forms and tear the beginning breach.Further, these breach need to accurately be aimed at described line of weakness.May be able to not always accurately aim at.Breach causes the loss of membrane material, and therefore, it is the selection that can not continue so.On the other hand, be easier to obtain jagged edge.To this, what all need to be done is to make jaw correspondingly have blade-like.In the situation of jagged edge, solved the problem of accurate control, because in the sawtooth incites somebody to action usually and a registration/alignment in the line of weakness.Preferably, the height of sawtooth is from 4 to 10mm, more preferably for from 5mm to 8mm and be most preferably 5mm.
Pouch
Can have any suitable shape or size according to pouch of the present invention.The large I of described pouch is arranged to shampoo or the toothpaste of packing unit dosage-usually about 10ml.This packing is called pouch better.Described pouch size also can be arranged to pack large-tonnage product-for example 5 or 10kg disincrustant powder.When described pouch had continuous boundary, it can have circle, ellipse or avette shape.In this case, at least 2 convergences from described many line of weakness that described continuous boundary begins form single line of weakness, and described single line of weakness is left towards described continuous boundary extension itself from least one set a distance of the starting point of described many line of weakness.
The height of preferred pouch is from 60mm to 650mm; Preferably from 70mm to 350mm.The width of preferred pouch is from 20mm to 400mm, preferably from 150mm to 200mm.Preferably, the height of top and sealed bottom section is from 10mm to 20mm, more preferably from 12mm to 18mm and most preferably be about 15mm.
On the other hand, when described pouch had a plurality of edge, described pouch can have the substantially shape of rectangle.This pouch also can have square, hexagon, pyramid or have any polygonal shape.With regard to this pouch, described many line of weakness can be since an edge and described single line of weakness can extend towards described same edge or neighboring edge from least one set a distance of the starting point of described many line of weakness and leave.
Described pouch can preferably have linear edge, but alternatively, described one or more of edge can be nonlinear or for example in WO2010136282A1 (NV of Uniliver) or the profile of describing among WO0123271A2 and the EP1631507A1 (all belonging to Cryovac company, 2006).Make the technical personnel in the field of FFS pouch and will know the shape that how to change them.
Described pouch can be that the typical case with 3 sealings rests the head on the formula pouch; Or has a quadrangle bag of more sealings.The quadrangle bag is similar to box and more stable and firm.Pillow formula pouch can have any cross-sectional plane-for example square, oblong, circle or triangle.Technical personnel will be understood that these terms.Described pouch can also be 4 sealing bags.This packing is sold with the curtain form of for example describing in WO06018140A1 (NV of Uniliver) usually.
Described pouch can also be doll pouch (doy pouch).The doll pouch is to have the upright pouch of round base portion and be generally used for backaging liquid materials.
A kind of especially preferred pouch has:
(ⅰ) be attached to the header board of rear plate by top seal section and opposed sealed bottom section, each sealing limits respectively top and the bottom margin of described pouch; And
(ⅱ) with at least one or a plurality of sealing of described top and the intersection of sealed bottom section, top or bottom margin on each from described front and rear panels of wherein said many line of weakness begin, and assemble in order to form single line of weakness at each plate, the edge of described single line of weakness between described top and bottom edge extends from the starting point of described many line of weakness and leaves, and at least one in many line of weakness at least one in many line of weakness on the wherein said header board and the described rear plate are aimed at.
This aligning can provide easier and tear beginning and easierly tear conduction.In the situation without the 3 sealing pouches (it also is called pillow formula pouch) that collapse section, described process control has better accuracy in the time of can allowing many line of weakness on aiming at described front and rear panels, because in this case, described pouch is formed by single width (sheet) film or lamination.Yet, collapse in the situation of 3 sealing pouches of section having side, always having line because collapse that the position of section changes may possibility not aligned with each other, because the described section of collapsing forms with very high pouch that speed is online to be formed.
(it is called pouch substantially in 4 sealing pouches, and be used to shampoo and other cosmetics of packing unit metering) situation in, described line is the possibility mis-aligned also, because in these cases, described pouch is formed by two width of cloth (sheet) film or the lamination that seal each other at predetermined point.Further, it is most preferred that, the single line of weakness on the described header board is aimed at the single line of weakness on the described rear plate.
In the situation of 3 sealing pouches, described the 3rd sealing preferably with described top and described sealed bottom section quadrature.
Pouch very preferably comprises that the opposite side with the inside folding part that is sealed in described top and sealed bottom section place collapses section, and the single line of weakness on the wherein said front or rear panel is extended to cross and describedly collapsed in the section one and intersect with single line of weakness on another plate.This pouch is called and collapses pouch.
The side section of collapsing also can be the pattern that is similar to cartoon larger zone is provided.Further, the side section of collapsing allow described pouch to expand and therefore described pouch can hold more contents.Except or replace side to collapse section, described pouch can have the bottom and collapse section.This section of collapsing allows described pouch upright, and therefore this pouch is known as upright pouch.
Although the single line of weakness that collapses in the section can be nonlinear; But it is most preferred that, described single line of weakness is straight line.Nonlinear line-for example wiggle is so not preferred in the described section of collapsing, because, in the situation that do not wish to be bound by theory, should think, when described line was bending, it stoped the described conduction of tearing that collapses in the section.This thing happens be because the tear edge that is applied by the user usually away from the body of described pouch, so described wiggle resists this power and will tear in the body that is directed to described pouch.
That on the other hand, should think that described straight (linearity) line of weakness that collapses in the section provides body that guiding leaves described pouch easierly tears conduction.This allows to remove fully the part of the big or small pouch that suitably arranges and a part that collapses section.
In further preferred pouch, described many line of weakness begin between the inside folding part of the 3rd sealing of another sealing-namely and described sealing.In this pouch, all line of weakness at described top or sealed bottom section and the inside part (it inwardly collapses the folding part and form because of described) that collapses ear produce.On the other hand, if produce one or more line of weakness described of collapsing in the ear, in fact so this line may not be of great use.
