[summary of the invention]
The present invention relates generally to but is not limited to a kind of packaging bag that is referred to as the child-resistant packaging bag, this packaging bag is made by the multilayer chip thing, and this multilayer chip thing has at least one outer plastic layer and at least one interior aluminium lamination in the face of article of mainly being made of polyethylene terephthalate (PET).For clarity, hereinafter will always mention pet layer.Yet, also can be without pet layer, and be to use ply of paper, oriented polypropylene (OPP) layer or oriented polyamide (OPA) layer.
In practice, these multilayer chip things are actual has constituted a lot of layers.Aluminium lamination inside almost always is placed with polyethylene layer separately and exclusively.And externally, similar multi-sheet printed material is arranged on described pet layer top usually, until be used for the protective clear layer of printed images.But these features are not that to solve this packaging bag of problem of the present invention-promptly more easily open necessary, therefore will its detailed description is omitted.
The packaging bag of being made by these flaps is widely used in drug products.Wherein, aluminium matter flap can be used for resisting external action owing to self stronger protective effect (as protective cover), and the PET flap then is utilized owing to self higher mechanical strength.When these packaging bags were designed to have protection of the child characteristic, if necessary, they also can be used for making full-refined " protection of the child " packaging bag.The manufacturing of protection of the child packaging bag has various prescriptive rules or by the special standard or the defined rule of reaching an agreement on.Under any circumstance, because said structure, be not difficult to open the package under the situation of subsidiary having, therefore, taked various ways in the prior art, so as under the situation of not losing protection of the child function as far as possible easier opening the package.
Therefore, need be with reference to U.S. Patent Application Publication the 2008/0038415th A1 number.Under the situation of the bar type of making by this multilayer chip thing, the packaging bag of this patent application provides a kind of easy-torn line, and this easy-torn line does not extend to the edge, therefore when opening the package, must fold the bar type in the easy-torn line zone, open the package along easy-torn line then.Therefore because think that children will can not fold bar type,, also this packaging bag is regarded as and had protection of the child function although have easy-torn line.Because only folding in " in the easy-torn line zone ", therefore the adult also usually is not easy to open this packaging bag.
About term " bar type ", should be understood to comprise the packaging bag of tubulose.In this tubular packaging bag, flap edge sealing has along the longitudinal formed body, and at predetermined position body is divided into independent space by horizontal edge sealing.In this case, usually vertical edge sealing roughly is arranged on the middle part of horizontal edge sealing length direction, thereby with vertical edge sealing facing surfaces on form to observe the surface, simultaneously owing to there is horizontal edge sealing, two usually very smooth and trend towards the clear-cut margin that becomes by the side margins that the bending of body material is formed in horizontal edge sealing zone, because these side margins weld mutually in the zone of horizontal edge sealing.Therefore the user would rather attempt opening the package in one of them horizontal edge sealing zone from the horizontal edge sealing that one of them side margins begins.The vertical and horizontal edge sealing should be interpreted as bonding or sealing band, with air-tight manner the body flap be joined together in gap area certainly whereby.
US Patent the 3rd; disclose a kind of packaging bag that is similar to sack or mat for 608, No. 815, this packaging bag has the vertical and horizontal edge sealing; but the subsidiary of opening of this packaging bag is arranged on the position that children see easily, and therefore this packaging bag does not have protection of the child function.US Patent the 6th, 102 discloses the special packaging bag of a kind of pattern No. 571, and this packaging bag has and is arranged in vertical edge sealing zone another and easily tears the zone, and purpose is to open the package for easier, and wherein flap is three-decker and is difficult to cracking.European patent also discloses a kind of bar type No. 1152947, and this patent has also been considered the problem in vertical edge sealing zone.The document of being quoted is by reference in conjunction with in this application, such as at when the U. S. application patent.
Except bar type, the packaging bag (being also referred to as mat) that is applied is especially arranged still in medical domain.This packaging bag comprises two common identical and symmetrically arranged flaps.These flaps are connected to each other (sealing usually) along the periphery of packaging bag.In a kind of structure, can be along a side margins folding of sheet thing, and then form a kind of packaging bag, when this packaging bag when being square, have the sealed type edge sealing on three sidepieces of this packaging bag, and on the 4th sidepiece the folding of sheet thing.A kind of structure in back is near bar type, but under the bar type situation, and vertically edge sealing always is positioned at one of them middle part of two outside faces; And under the mat situation, then formed the sidepiece edge sealing, and consider and to distinguish mutually with horizontal edge sealing from technical standpoint.
The objective of the invention is to tear subsidiary, therefore do not make and auxiliaryly tear performance and protection of the child performance is affected for bar type and mat provide.
According to the present invention, above-mentioned purpose realizes by the described technical scheme of claim 1.
Therefore, the present invention be in essence be provided with at least one surface of packaging bag with bar type edge or mat edge between have two easy-torn lines that intersect of certain distance.Every easy-torn line preferably extends with the form of straight line, and wherein the angle at the intersection point place is 60 ° to 90 ° between two easy-torn lines.
Therefore, at bar type and especially under situation according to the bar type of above-mentioned U.S. Patent Application Publication 2008/0038415A number, can more easily open bar type, because packing can be torn bar type along easy-torn line easily along an easy-torn line and also accurately folding in the zone of another easy-torn line.Therefore, should be noted that: because article may accident spill, therefore as above-mentioned document, it is inappropriate that easy-torn line is arranged on the bar type surface.Other document of above mentioning does not belong to same type.Especially No. the 4th, 762,514, the US Patent mentioned of beginning, although it has similar structures, still need to redesign afterwards.
Under the bar type situation, especially under the mat situation (from essence, than more being difficult to catch and fold one of them packing material surface under the situation of bar type), these easy-torn lines are aligned with each other, and are formed on two surfaces of packing material.Especially, in this modification, this is favourable: be provided as the tear line of two or greater number form at least, promptly provide parallel to each other and separate two or more easy-torn lines of segment distance each other, because behind folding two packing material surfaces, tear line is not alignment accurately usually.Under the situation of wrapper and shrink film, the distance that needs to keep is in fact less than the distance between the easy-torn line of above mentioning, and yes for its purpose in order to form mechanical strength bar preferably between easy-torn line.Preferably, this distance is less than 1mm, more preferably less than 0.5mm, particularly preferably less than 0.1mm.
Although when folding, can be offset by occurrence positions usually, always increasing of easy-torn line quantity guaranteed that tear line in fact aligned with each other exists.After suitably revising, this situation also is applicable to fold line.Hereinafter, for simplicity's sake, only mention an easy-torn line, unless when explaining many easy-torn lines.Under the various situation of this easy-torn line quantity, term " intersection point " has become cross facet, yet because its size is less, therefore when with respect to some description cross facet, the characteristic of intersection point also is applicable to cross facet.
In first modification, wherein easy-torn line neighboring edge of being parallel to packaging bag extends, and another easy-torn line then extends perpendicular to the neighboring edge of packaging bag in fact.In the case, both intersection points preferably and spaced apart between the nearest corner of packaging bag.In this modification, the easy-torn line that is parallel to the neighboring edge extension is generally fold line, and the easy-torn line that extends perpendicular to described neighboring edge then is a tear line.In the case, be parallel to fold line and the distance between the latter that neighboring edge extends and be preferably between the 3-20mm, more preferably between 10-15mm, thus easier extracting and bending.
In another embodiment, intersection point seals outside the edge sealing zone but be positioned near one of them corner of packaging bag; Article two, easy-torn line has then rotated about 45 ° with respect to the packaging bag edge.In this modification, in order to tear whole packaging bag, the easy-torn line that the corner is cut away is preferably fold line, and the easy-torn line that extends in the corner then is preferably tear line.Iff wanting to open osculum, then can replace the function of above-mentioned line.This can show at an easy rate by corresponding label.
Article two, or the intersection point between many easy-torn lines preferably transfer in the corner, thereby can cosily grasp packaging bag, and then packaging bag is opened.In each case, it is long that the fold line on the intersection point both sides should be at least 15mm, and it is long to be preferably 20-25mm.Easy-torn line then can be shorter, and this easy-torn line allows folding easier, and guarantees to fold in the tram.Have in packaging bag under the situation of rectangle or square profile, this means that intersection point is positioned on the angular bisector, and far away with the corner 15-25mm of being separated by.
The use of packaging bag is described below.
User's wherein folding bag pack in two easy-torn lines, another in two easy-torn lines opens the package then.In first modification, the user tears packaging bag then along being parallel to that easy-torn line folding bag pack that extend adjacent corner on the direction perpendicular to this corner.Under the situation of rectangle or square packaging bag, the user is along the easy-torn line folding bag pack of in fact cutting away the corner, in fact begins packaging bag is torn from corner areas along the direction of angular bisector (45 °) then.
As can be seen from the above description: two easy-torn lines are arranged on one of them outside face of packaging bag, and allow these easy-torn lines align with similar easy-torn line on being arranged on the opposite side of packaging bag, this is favourable, make that so in fact the easy-torn line of tearing for the user has formed two easy-torn lines, reason is that easy-torn line is present in equably with in avulsed two panel region.
Describe the present invention in detail below in conjunction with accompanying drawing.
[description of drawings]
Fig. 1 has showed the plan view of first embodiment;
Fig. 2 has showed the plan view with similar second embodiment of Fig. 1; And
Fig. 3 has showed a variant embodiment.
[specific embodiment]
Fig. 1 has showed the packaging bag of shape of cushion.This packaging bag is formed by two preferably identical flaps 7,7 '.The packaging bag 1 that is essentially rectangle forms by four sealing edge sealing 2,3 are combined.In the case, two sealing edge sealing 2 extend parallel to each other, the extension also parallel to each other similarly of two other sealing edge sealing 3, but but perpendicular to sealing edge sealing 2.
The last figure of Fig. 1 has showed that along the schematic sectional view of line A-A this figure has omitted article and has been positioned at the sealing edge sealing 3 of cross-wise direction, so that show major part.In last figure, can see sealing edge sealing 2, also can be clear that two flaps 7,7 ' that constituted described packaging bag 1.It should be noted that: the cross section perpendicular to the A-A line is exactly the cross section of being seen in last figure.
According to the present invention, the subsidiary of tearing with two easy-torn lines, 4,5 forms is arranged in one of them the zone of sealing edge sealing 2,3.In the case, easy-torn line 4 is parallel to neighboring edge 2 and extends, and easy-torn line 5 extends perpendicular to neighboring edge 2 in fact.These two easy-torn lines not only are arranged on can be from the top flap 7 that Fig. 1 sees, and is set in place on the flap 7 ' of bottom.Therefore.The user uses easy-torn line 4 as wiggle, the result is that easy-torn line 5 (packaging bag 1 is torn along this easy-torn line 5) extends to by in the present wiggle 4 formed fringe regions, though and the thickness of this fringe region to become twice thick, now still can be easily packaging bag be torn along easy-torn line 5.
The structure of easy- torn line 4,5 and length depend on the article in the size, packaging bag 1 of packaging bag 1, depend on whether plan packaging bag is divided into two parts at least simultaneously, perhaps whether packaging bag to have an opening that can be removed just enough.
Usually in field of medicaments, transfer to pill, sugar-tablet, contact lenses, powdery or particulate material in another container with planning from packaging bag, other gel or the viscous material of perhaps planning to allow the user occupy are packaged in these packaging bags.Give an example as can be seen from above-mentioned: can have multiple multi-form removal selection scheme, thereby can form the subsidiary of tearing according to various ways of the present invention.Be used under the situation of other article, under the situation such as the less but expensive assembly of the volume that is used for spices, electron trade or cosmetic industry, the opening of the packaging bag of these mats or bar type shape even need meet more conditions.
Fig. 2 has showed a variant embodiment.In the figure, easy- torn line 4,5 is moved in one of them corner of packaging bag 1, and easy- torn line 4,5 perhaps extends perpendicular to article one easy-torn line in fact along the angular bisector extension of sealing edge sealing 2,3.In the case, can be along easy-torn line 4 bends package bags, tear packaging bag along easy-torn line 5 (promptly in fact along the diagonal of packaging bag) then.As can be seen: can under open configuration, form big opening, not have the danger that causes Individual Items to run out or lose simultaneously such as the contact lenses accident.
Therefore, also can tear packaging bag along easy-torn line 4 then along easy-torn line 5 bends package bags, the result is: have at easy-torn line 4 under the situation of suitable length, the corner of packaging bag has been disconnected.When planning scrappy material or fluent material taken out from packaging bag 1, this is particularly useful.
Fig. 2 has also showed a variant embodiment of packaging bag 1, the especially only packaging bag of being made up of a flap 7.This flap 7 is 6 folding along the edge, and is closed by sealing edge sealing 2,3 along remaining three edges.This sees too clearly in the last figure of Fig. 2, and this figure has also showed along the schematic cross-sectional of A-A direction.Certainly, at this, also can provide the subsidiary of tearing that is similar to Fig. 1.Easily open the package if desired, then the described subsidiary of tearing can be arranged in the zone of folded edge 6, because, do not need to tear wherein sealing edge sealing when along the easy-torn line bends package bag that is parallel to edge 6 and when opening the package subsequently.
Fig. 3 has showed the plan sketch of the variant embodiment of bar type packaging bag of the present invention.In the case as can be seen: have two folded edges 6,, and formed vertical edge sealing 2 ' in this position because cooresponding sealing edge sealing 2 has moved to one of them surperficial midway location.In the exemplary embodiment of being showed, showed to be used to the easy-torn line 5 that is parallel to the easy-torn line 4 of vertical edge sealing bending and is used for tearing packaging bag perpendicular to this longitudinal edge.
Obviously: can change the angle between two easy-torn lines 4,5.If yet low-angle between the two become less than 60 °, when tearing, can go wrong, preferably as far as possible two easy-torn lines are arranged to the right angle state for this reason.Whether image pattern 2 is such, allows two easy-torn lines be parallel to one of them side margins, perhaps with respect to the bisector symmetry of the angle between two edges in the corner, depends on above-mentioned various situation.
Easy- torn line 4,5 is arranged in the pet layer, because this layer determined the mechanical tear intensity of the lid of packaging bag 1.Simultaneously, also provide first visual subsidiary, opened a little so that find.Preferably, strengthened this direction subsidiary by printing corresponding pattern in packaging bag 1.Can make easy- torn line 4,5 by any any means known, make such as mechanical means or high power-beam, the means that are preferably laser.Wavelength of Laser and power are adjusted into the materials used adaptation with institute, unquestionable for those skilled in the art.Also be out of question with respect to flap guiding laser.Therefore, do not need it is gone through.
Own about easy- torn line 4,5, should be noted that: they needn't extend with the form of straight line, but also can be waveform or curved shape.The mode that these easy-torn lines can be same as the easy-torn line of institute's schematic presentation anything but forms.These easy-torn lines can be for the pet layer tender or even the part pet layer removed the easy-torn line that the back forms.These easy-torn lines can maybe can be dotted line or dash line for the continuous lines bar.Manufacturing and well-known, and widely record to the effect of opening.Knowing under the situation of the present invention, also can make it have needed value by several simple tests.
At last, as described in, can be arranged to the easy-torn line of two or greater number form, such as fold line (flap of packaging bag is along the fold line bending), so that make bending easier.
As known easy-torn line and tear subsidiary, the most basic is: the defencive function of packaging bag in easy- torn line 4,5 zones (being aluminium lamination) cannot be destroyed.
Packaging bag needn't one be decided to be square or rectangle.Also can use the packaging bag or the profile packaging bag of local bending at least of polygonal profile.Therefore, term " be parallel to " and " perpendicular to " refer to the tangent line or the secant at this position.
