Description

There is the pouch of laser scratch
Technical field
The present invention relates to a kind of pouch for packaging, relate more specifically to that there is line of weakness so that the pouch that can readily open of pouch.
The present invention is developed to be mainly used in scale remover, and will describe with reference to this should being used for thereafter.It is to be understood, however, that the present invention is not limited to the use of this specific area.
Background technology
Any discussion to prior art is all not construed as being to recognize that this prior art is well-known or forms the part of public general knowledge for art in this manual.
Flexible pouch (also becoming pouch or bag) is used for packing various product.Most of pouches are filled in molding and are made and fill on (FFS) machine of sealing.The film of any damage during pouch can be resisted transport by intensity, be stored and operate is made.
Need to open pouch to empty receiving material.But, some pouch is difficult to open, because sealing very strong, or because plastic foil is tough and tensile.When pouch or hands moisten, may be more difficult to open.Such as, it is extremely difficult for opening shampoo pouch with wet hands.Typically require pocket knife or shears.However, it is possible to be not to obtain pocket knife or shears at any time.In their absence, user may attempt to open by force pouch.Usually, the uneven and described pouch of this power is split or receiving material is overflowed.This development causing easily tearing pouch.
Easily tear pouch is made up of the superfine plastics easily tearing, or they have tear breach or the line of weakness being adapted to assist in tear.
The pouch with reduction tear line is known.Laser is widely used to form line of weakness, but other the most mechanical weakening modes are also known.
Preferably, in the situation with the pouch of laser scratch line of weakness of line of weakness-especially, start tear and tear conduction is easy.Tear conduction also should desirably face the side of pouch, in order to a part (typically corner) for described pouch of can easily tearing.The shortcoming of some laser scratch pouch is difficult to start tear and tears conduction uncontrolled.Sometimes, in tear conduction to the body of pouch, rather than towards the side of pouch.
US5158499A (American Can Company, 1992) makes the trial solving this problem.That application discloses near or adjacent to sealing multiple linearly or the most straight continuous laser score line, and described line extends across the whole width of pouch.We have determined that linear tear line can not always be to provide controlled and guided tear-propagation.When opening pouch along linear line of weakness, tear can be conducted beyond limiting path and entering the body of pouch.We have also determined that linear laser score line needs the laser scratch in reduction-such as this application to become the obvious degree of depth.This needs higher laser power and expends more electricity.
WO2009/110398A1 (Hosokawa Yoko company limited) discloses a kind of for a large amount of receiving material of easily primary emission and be easier to the bag grasped in use.That application discloses a kind of bag with bag body, described bag body has the first and second sides and the 3rd side intersected each other, and described 3rd side rolls relative to described first and second and tiltedly extends and limit opening.Spray unit is connected to bag body and protrudes from the 3rd side.Described spray unit includes the slide fastener being positioned at bag body interior.Described bag body may also include and the tear portion tilting the 3rd side superimposed.Described tear portion can be formed by having the rough surface of minute aperture set by making the thinning formation of layer or it.U-shaped recessed portion is located remotely from slide fastener, and at least one in the first and second sides for grasping described bag and is formed.The document does not disclose the line of weakness of the part for tearing bag.
US2010/0226598A1 (Stoeppelmann) discloses pouch, and described pouch has 3 linear tear lines for controlled and guided tear-propagation.Described 3 line of weakness are spaced apart from each other.Intermediate line is shorter much than other 2 lines.Described intermediate line is provided with tear and starts breach.Other 2 lines described extend across the width of pouch.In use, user can start tear at intermediate line and when user is completely torn apart described intermediate line, the power of any excess makes tear line move on to described first from described point or move on to described second line of weakness.Tear after leaving middle line of weakness in described 2 outer line of weakness, on which bar, conduct the direction depending on acting on tear edge.Therefore, described intermediate line starts tear, and outer line of weakness controls and guides tear conduction simultaneously.
We it has been determined that when automatic moulding is filled in sealer when pouch online molding packaging film experienced by visibility point and change.This position change not always allows the line of weakness on the header board of pouch to align to the corresponding line of weakness in back plate.It is directed at additionally, this position change not always allows tear to start breach with predetermined line of weakness.
If described line is not aligned with, if or described tear start breach and be directed at line of weakness, then the purpose of easily tear is possible will not be realized.This problem can be solved by deeper line of weakness, but this may increase cost.When under the effect of the stress applied when operating on sealer is filled in molding, the mechanical strength of the pouch obtained by punching press will be reduced.
Accordingly, it would be desirable to a kind of pouch, described pouch can easily start tear and conduct tear with bigger control and accuracy;Even when being formed on FFS machine and filling described pouch and film is also such when having a certain amount of position change.
We have determined that when at least 2 during pouch has a plurality of at least part of non-linear line of weakness and described line of weakness are converged to single line can solve this problem.The line of weakness that the feature of the non-linear line of weakness of a plurality of part is easy on header board is alignd to the corresponding line of weakness in back plate and starts tear.In line of weakness at least 2 are converged to the feature of single line and allow controlled and guided tear-propagation so that a part for described pouch can easily remove.
Summary of the invention

A plurality of line of weakness
Although described pouch can easily tear when at least 2 in described a plurality of line of weakness assemble and form single line of weakness;It is preferred that form single line of weakness from described continuous boundary or institute's wired all can gathering of a beginning from the plurality of edge.This can improve tear further and starts and especially tear conduction so that a part (preferably certain part at edge) for described pouch can more easily be torn.
Described single line of weakness can extend towards described continuous boundary, same edge or neighboring edge.In this case because tear conduction can directed by described single line of weakness and control, most of pouches can easily tear.
After easily having torn the overwhelming majority of pouch, can by apply certain power tear remainder, if or opening be enough to easily access receiving material and also can stay in described pouch.If it is desire to tear weakening part completely and to reduce active force further and by providing easier tear conduction to the preferably control of tear;Preferably, described single line of weakness extends to described continuous boundary, same edge or described neighboring edge.
Although described a plurality of line of weakness is the most nonlinear;It is preferred that every in described a plurality of line of weakness is all bending.When compared with other kinds of non-linear profile, which provides preferably tear conduction and control.The line radius of curvature when they bend, depends on the size of described pouch/bag.Preferably, the radius of curvature of every in described sweep is all between 10mm to 150mm.
Described single line of weakness can be linear, it is preferred that bending.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 is between 10mm to 150mm.
Preferably pouch has at least 3 line of weakness.In this case, it is further preferred that, described in described Article 2 linear distance first and described Article 3 line be equidistant, until described line assemble.
The method weakened
Following method can be used to produce line of weakness, include but not limited to: cut, perforation, chemical treatment, preferably the combination of laser scratch, laser beam perforation, mechanical mark, machine drilling, method for stamping or these methods.
Described line of weakness was preferably formed before film is formed as pouch in the film, but alternatively, and the most preferably, can pouch manufacture during or after by be attached to molding fill sealer scoring devices-such as laser scratch device introduce described line of weakness.In a preferred method, the material of described pouch weakens in specific location.
This can align with the figure on material so that when filling and process described material in molding on sealer, described line of weakness occurs at desired locations.Manufacture and there is line of weakness so that the technical staff in field of the pouch opened will appreciate that the position how handling these line of weakness.
It is particularly preferred that every in line of weakness is all laser scratch, so line can more easily tear off and they provide and tear starts and tears preferably controlling and accuracy of conduction.
In order to use laser, there is enough wattages in case the laser beam focus of a part for evaporating film on the membrane.Using of laser technology allows control the degree of depth or penetrate into described film complete perforated from the trickleest cut.Optical maser wavelength can be in the range of about 0.2 to about 40 μm.
Described laser beam can use with monotype structure or multimode architecture.Further, described bundle can be pulse or continuous print.Can use pulsed beams to form interrupted or discontinuous cut, but preferably use continuously bundle when continuous print is easily opened line of weakness when expectation obtains.
Laser output power can have any wattage.Such as preferably use high wattage when expectation laser sends a plurality of bundle.Therefore, laser power can be in the range of up to 500 watts, in order to use while allowing such as 5 100 watts bundles or 10 50 watts bundles.
Can be by any known manner-produce a plurality of bundle by partial reflector beam splitting.Generally, the beam power of use can change according to the relative motion between multiple structure or processed film or the thickness of lamination and described bundle and described workpiece.The arbitrary arrangement that can use described bundle combines.
Alternative as laser can use blade.Described blade is arranged on engraving post, and described engraving post is directly installed on film handling machine to complete cutting before forming described pouch.
Different blade design can be used to obtain the line of weakness of different pattern.The pressure being applied to blade also changes during processing, in order to the size of control cutting and the degree of depth are so that it is guaranteed that bag readily opens.
Impressing is another alternative for line of weakness.Stamping technique carrys out weakened film in specific region by pressure, temperature, time and deformable contour.Expected result be by change impressing track at measuring instrument and/or material structure realize.Infrastructure device for impressing includes the jaw that can press against back plate.Deformable contour or pattern are fixed to described pawl and are heated.Described film is squeezed between described deformable contour and described back plate.The variable of this process of known effect is layer tension, rear panel material, rear plate thickness, rear plate temperature, pawl pattern and the pawl thickness after layer tension when heating-up temperature, chilling temperature, pressure, heat time heating time, cool time, impressing, impressing.

Described line of weakness can have pattern.Those patterns can be to take the form of continuous lines, dashed line or combinations thereof.It is, however, most preferred that pattern be dashed line, wherein said dashed line is formed by multiple cut sections.The length of every cut section can change as follows: between 0.12mm to 4.4mm, preferably between 0.3mm to 2mm, and most preferably between 0.6mm to 1mm.Distance between adjacent cut section can change as follows: from 0.4mm to 4mm, preferably from about 1mm to 3mm, and most preferably between 1.5mm to 2mm.Its intensity of the characteristic of the thickness according to film and film-especially is changed by scratch depth.The length ratio of cut section and non-cut section can be had along every line of weakness.This ratio is preferably from 1 to 2.In other words, cut section will be the half of length of the non-cut section of the centre between each scored portion.
Most preferably, get laser scratch line ready and be made for have the laser power of minimum 200 watts, thus by speed controlling to 5mm/s and control in 60 μ s pulse widths.
Although can in described a plurality of line of weakness one or more on arrange tear start breach;But alternatively and more, one in described continuous boundary or the plurality of edge is jagged.Need to go out tear from the pouch formed and start breach.Further, these breach need accurately to be directed at described line of weakness.May be able to not the most accurately be directed at.Breach causes the loss of membrane material, and therefore, it is the selection that less can continue.On the other hand, it is easier to obtain jagged edge.To this, be there is a need to do is to make jaw correspondingly have blade-like.In the situation of jagged edge, the problem solving accurately control, because in sawtooth is by a registration/alignment generally and in line of weakness.Preferably, the height of sawtooth is to 10mm from 4, is more preferably from 5mm to 8mm and most preferably 5mm.
Pouch
Pouch according to the present invention can have any suitable shape or size.The size of described pouch can be set to shampoo or the toothpaste of packing unit dosage-generally about 10ml.This packaging is preferably referred to as pouch.Described pouch size may also be arranged to pack large-tonnage product-such as 5 or 10kg scale remover powder.When described pouch has continuous boundary, it can have circle, oval or avette shape.In this case, at least 2 convergences from the described a plurality of line of weakness that described continuous boundary starts are to form single line of weakness, and described single line of weakness itself is extended towards described continuous boundary from least certain distance of the starting point of described a plurality of line of weakness.
Preferably the height of pouch is from 60mm to 650mm;Preferably from 70mm to 350mm.Preferably the width of pouch is from 20mm to 400mm, preferably from 150mm to 200mm.Preferably, the height in top and sealed bottom portion is from 10mm to 20mm, more preferably from 12mm to 18mm and the most about 15mm.
On the other hand, when described pouch has multiple edge, described pouch can have the shape of general rectangular.This pouch also can have square, hexagon, pyramid or have any polygonal shape.For this pouch, described a plurality of line of weakness can start from an edge and described single line of weakness can be extended towards described same edge or neighboring edge from least certain distance of the starting point of described a plurality of line of weakness.
Described pouch preferably has linear edge, but alternatively, described one or more of edge can be nonlinear or such as profile in WO2010136282A1 (Uniliver NV) or described in WO0123271A2 and EP1631507A1 (broadly fall into Cryovac company, 2006).The technical staff in the field manufacturing FFS pouch will appreciate how to change their shape.
Described pouch can be the typical pillow formula pouch with 3 sealings;Or there is the tetragon bag of more sealing.Tetragon bag is similar to box and more stable and firm.Pillow formula pouch can have any cross section-such as square, rectangle, circle or triangle.Skilled person will appreciate that these terms.Described pouch can also is that 4 sealing bags.This packaging is generally sold with such as curtain form described in the WO06018140A1 (Uniliver NV).
Described pouch can also is that doll pouch (doy pouch).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:
() is attached to the header board of back plate by top sealing and opposed sealed bottom portion, and each sealing limits top and the bottom margin of described pouch respectively;And
() and described top and at least one or more sealing of sealed bottom portion intersection, from the beginning of top on each from described front and rear panels of wherein said a plurality of line of weakness or bottom margin, and assemble to form single line of weakness on each plate, described single line of weakness is extended towards the edge between described top and bottom edge from the starting point of described a plurality of line of weakness, and at least one in a plurality of line of weakness on wherein said header board is directed at at least one in a plurality of line of weakness in described back plate.
This alignment can provide easier tear to start and easier tear conduction.In nothing collapses the situation of 3 sealing pouches (it is also known as pillow formula pouch) in portion, described process control can allow there is more preferable accuracy when a plurality of line of weakness being directed in described front and rear panels, because in this case, described pouch is formed by single width (sheet) film or lamination.But, in the situation of 3 sealing pouches there is side collapsing portion, always there is line because the probability collapsing the position change in portion and may be the most aligned with each other because described in the portion of collapsing be to form speed with the highest pouch to be formed online.
In 4 sealing pouches, (it is generally known as pouch, and be used for packing unit metering shampoo and other cosmetics) situation in, described line is likely to misalignment, because in these cases, described pouch is formed by two width (sheet) film sealed against one another at predetermined point or lamination.Further, it is much preferred that the single line of weakness on described header board is directed at the single line of weakness in described back plate.
In the situation of 3 sealing pouches, described 3rd sealing is preferably orthogonal with described top and described sealed bottom portion.
Highly preferred pouch includes that the opposite side with the fold inward portion at described top and sealed bottom portion that is sealed in collapses portion, the single line of weakness in wherein said front or rear panel extend across described in collapse in portion one and intersect with the single line of weakness on another plate.This pouch is referred to as collapsing pouch.
The side portion of collapsing can be also that the pattern being similar to cartoon provides bigger region.Further, the side portion of collapsing allows described pouch to expand and the most described pouch can accommodate more receiving material.Except or replace side collapse portion, described pouch can have bottom collapse portion.This portion of collapsing allows described pouch upright, and the most this pouch is known as upright pouch.
Although the single line of weakness on collapse in portion can be nonlinear;But it is highly preferred that, described single line of weakness is straight line.Nonlinear line-such as sweep described collapse in portion be less preferably as, in the case of being not intended to be bound by theory, it should think, when described line be bending time, it stop described in collapse in portion tear conduction.The tear edge that this thing happens is because being applied by user is typically remote from the body of described pouch, so during described sweep resists this power and tear is directed to the body of described pouch.
On the other hand, it should collapse straight (linearly) line of weakness in portion described in thinking and provide the easier tear conduction of the body being channeled out described pouch.This allows remove a part for the pouch suitably sized arranged completely and collapse the part in portion.
In further preferred pouch, described a plurality of line of weakness starts between another sealing-the i.e. the 3rd sealing and the fold inward portion of described sealing.In this pouch, all line of weakness are in described top or sealed bottom portion and collapse that the inward portion (it be because described inwardly collapse folding part and formed) of ear is upper to be produced.On the other hand, if producing one or more line of weakness on described collapsed in ear, then this line is actually not likely to be very useful.

Detailed description of the invention
In the detailed description to accompanying drawing, like reference numerals is used for representing similar characteristics.
Fig. 1 is to have 3 sealings and side collapses the front view that the preferred implementation of sealed pouch is filled in the molding in portion.Described pouch has the header board 1 being attached to back plate (not showing in this view).
Pouch has top sealing 2 and opposed sealed bottom portion 4, and described top sealing 2 has top jagged edge 3, and described sealed bottom portion 4 has the bottom jagged edge 5 of correspondence.Header board 1 is attached to back plate by top sealing 2 and opposed sealed bottom portion 4.
Distance between top jagged edge 3 and bottom jagged edge 5 limits the length of pouch.The width of pouch is to be limited by the distance between edge 6 and opposed edge 7.These sizes can depend on changing the amount of the material being packaged in pouch.Top sealing 2 and sealed bottom portion 4 have seal line (being represented by same numbers 1a).At these seal lines 1a, because the opposite side with fold inward collapses portion and seals at top and sealed bottom portion, 4 tunics are sealed to together.The header board 1 of the partially defined pouch between the top jagged edge 32 sealing lines 1a on top sealing 2 and the common top of back plate (not showing in this view).Similarly, the common base edge of the header board 1 of the partially defined pouch between the bottom jagged edge 5 two sealing lines 1a in sealed bottom portion 4 and back plate.
Adjacent corner in pouch, there is the nonlinear curve 8,9 and 10 of 3 laser scratch that the jagged edge 3 from header board 1 starts, and institute is wired to be focused on header board thus forms single laser cut line of weakness 11, and described single laser cut line of weakness 11 extends to the edge 6 between top and bottom edge.Distance (before they are assembled) between the nonlinear curve 8 and 10 of laser scratch is minimum in the case of tolerable, because this will be easy to beginning and the conduction of tear.Sawtooth on top jagged edge 3 provides the starting point of tear, because in sawtooth will overlap with in line of weakness.
Fig. 2 is the rearview of the embodiment of Fig. 1.Because pouch is 3 resealing pouches, described pouch has the wing sealing 13 orthogonal with top sealing 2 and sealed bottom portion 4.Having seal line (being represented by same numbers 12a) on top sealing 2 and sealed bottom portion 4, these seal lines describe the most in FIG.Just as header board, back plate 12 also has 3 laser scratch lines 14,15 and 16, and described laser scratch line starts from top jagged edge 3 and assembles over the plates thus form single laser cut line of weakness 17.Described single laser cut line of weakness 17 extends to the edge 18 between top and bottom edge.Described pouch also has another edge 19.
The nonlinear curve 8,9,10 of the laser scratch on header board 1 and single laser cut line of weakness 11 laser scratch line corresponding in back plate 12 14,15,16 and single laser cut line of weakness 17 are directed at.
