Abstract
This invention relates to a method of creating a seal for a container with a transparent film. This method has particular application to the use of thin films with rings that form the top of a can. Embodiments of the invention that incorporate a gas indicator into the seal are also discussed.
Description
Technical field
The present invention relates to seal of vessel.
Background of invention
Briefly, in specification sheets of the present invention, will relate to container from start to finish, jar for example, the improved content of leak free.Yet, can imagine that the present invention also can be used for other and use.
For clear, this specification sheets will be limited to from start to finish and be used for foodstuff storing and other corrosion-prone article jar.Yet, also having, the present invention can be used in the analogue beyond this area, and the container that is used to store other material.
What can re-use after design-calculated is opened usually is annulus-lid-film (RLF) type jar.In new zealand patent 218651, disclosed a kind of such jar, it uses the hole of this jar of a kind of opaque thin slice foil sealing.Usually, this jar has an interchangeable lid, in case thin slice is removed, it can be used in this container of sealing.
The typical method of making leak free RLF jar is that continuous aluminium foil is passed through a ring/lid arrangement.A model pushes aluminium foil in each groove of ring cowling device.The characteristics of aluminium foil are, in case be bent in these holes, it can keep its shape, and with respect to the position of ring.
This packaging technology also comprises: sealed mixture is joined in the groove of ring.
The above-mentioned ring cowling and the processing of film assembly when being packaged into material in the sealable tank, are one of the slowest steps.Therefore, process a large amount of this assemblies in advance usually, deposit then, up to the technology of the package of using it for subsequently.
Subsequently, the limit of tank body is placed on the sealed mixture.Huan outer edge folded roll is reduced on the limit of jar subsequently, forms gas tight seal.
Subsequently, material is put into tank body.If material is a milk powder, will improve pack environment so usually.
As final step, the bottom of jar is placed on the tank body, will vacuumize in the jar and jar be sealed up.
Unfortunately, above-described jar has some problems usually.
A problem is that beginning needs to cut or draw back the film that is sealed on the jar in order to obtain being stored in the product in the jar.Doing like this through regular meeting causes the fractionlet of film to pollute food in the jar.
With this problem association be the sharp edge (because cutting action produce) of film, it can hurt the customer that its content is got in the interior flood of jar.
Another problem of jar commonly used is before film is removed, to can't see the content in the jar.
Whether this is to be worth being concerned about because can not detect jar whether swindleness is arranged, perhaps enough fresh in to be used for consumption.
In order to overcome these shortcomings, to improve, method is that the transparent plastic material of a bed thickness is installed on jar, seals jar below lid.Usually these thin layers are made with polyvinylchloride (PVC), and it is shaped as hard disk, about 340 microns of thickness.
Unfortunately, this improvement has occurred other problem again when having overcome some shortcomings relevant with the opaque foil sealing of use.
By making the method for disk (injection moulding), with to compare cost by the method for using continuous aluminum foil film higher.
Another subject matter relevant with using transparent disc appears in the actual process of using disk in annulus and cover means.
At first, if the injection mould that is not ready for is annotated, the shape of plastic material must well cutting.Because the rigidity characteristics of disk, disk must be thermally processed into the profile of annulus.At last, annulus must be installed to the top of ring/lid arrangement.
It is duplicate that the rapid method of this multistep is compared with the method for using aluminium foil, therefore is a kind of slow and more expensive method.
Another problem of thick transparent membrane is that the content difficulty in the access jar is because thick film is difficult to open for consumers.
Use thick film to also have another shortcoming, film is crimped onto on its position by mechanical means.Make that like this circular ring cover device can not be with the method installation same with the RLF device that uses aluminium foil.Therefore, the circular ring cover device for disc can only make this method significantly slack-off as a part of jar manufacturing process like this.Can be sure of that when most of jars were made, this technology be hand-manipulated, efficient is very low and expense is very high like this.
Therefore, need provide a kind of method that seals jar, the visuality of transparent membrane and the processability advantages of chemistry advantage and aluminium foil can be got up.
An object of the present invention is, overcome the fwd problem, or be at least the public a useful selection is provided.
The advantage of others of the present invention will be clearly by the specific descriptions of example.
Summary of the invention
According to one aspect of the present invention, provide a kind of encapsulating method that is used for container at this, sealing comprises a fexible film with certain visual diaphaneity, the characteristics of this method are to comprise the steps:
A) annulus is placed on the fexible film, and
B) make the external form of film consistent with the part surface of annulus at least,
Wherein film and annulus are by the sealing of the clot bond between them.
According to related aspect of the present invention, provide a kind of sealing that is used for container at this, described sealing comprises an annulus and a fexible film, fexible film sticks on the annulus by the clot bond between annulus and the film.
According to another aspect of the present invention, provide a kind of jar at this, it comprises a kind of cardinal principle such as above-mentioned described sealing.
As a jar, this container will be mentioned in this manual from start to finish.Yet, should be understood that principle of the present invention can be used in and use always the container that jar has different structure.For example, container can be box-like structure, perhaps makes with other material except that steel commonly used.
Can see that in a preferred embodiment, the annulus structure compared that annulus and jar device commonly used use is with less.Yet, should be understood that this annulus should be and has some devices that are used to make the hole that the content of jar enters with jar bonded assembly mechanism and some.
In a preferred embodiment of the invention, this annulus provides a lid for film, and is identical with the position of RLF device commonly used.Yet, should be understood that in some embodiments of the invention, in this step, perhaps in some other steps, do not need to provide lid.For example, may only need a film-type sealing rather than an additional lid that re-uses.
This film can be for having any film of above-mentioned character.This film preferably has enough flexibilities, so that can roll, thereby can enough methods identical with using aluminium foil use.Common this film is more thinner than previously used thick transparent membrane.
The film of Shi Yonging is made with plastic material in a preferred embodiment, and is optional in this case, and is understood that principle of the present invention can be used in the film that other material with required character is made.
If film is made with plastic material, can know that because this film has needed flexibility of sealing and durability, the thickness of this film should be at about 100 microns.Certainly can use the film of other thickness.Typical range is the 20-200 micron.
According to builder's different needs, the visual diaphaneity of film can be different.Although in a preferred embodiment, film is that full impregnated is bright, and this is not essential.For example, film can have zone of opacity and transparent region " window ".This can be that cause in the zone with different materials, and/or dyeing or printing process cause.
In other embodiments, film can have opacity to a certain degree for translucent.
Important feature is, film provides a kind of means, and whereby, the content of jar can see through film and see.
Some surfaces of film and annulus are met.
In one embodiment, can the profile of film and annulus be met by using a model, the profile of this model is made the profile that the suitable part of film can be pressed into annulus.
In other embodiments of the invention, can obtain, for example, use D.I. or common air pressure by pressure forming.
In other embodiment of the present invention, the profile of film and lid meets and can obtain by vacuum forming, for example by use vacuum below the RLF device.
Vacuum forming and pressure forming can access an advantage, promptly film can with combining that lid acquires a certain degree.
If enter high height above sea level from low height above sea level, the gas in the jar will expand.This will make the sealing film of jar upwards push away, and make lid open or make film breaks under situation about having.Obviously this will cause serious problems.
Yet if film and lid stick to a certain degree, it still is bonded together lid and annulus, thereby it can not be turned down lid from jar.
Another advantage that film has some clot bonds to stick on the lid is that film has only surf zone seldom to allow oxygen to enter.Minimum permission inlet means can use more cheap prevention material.It is when if the present invention is used for packing ratio milk powder and article that coffee-for example coffee bean is cheap, significant.
As can recognizing, the physical property of film is different with aluminium foil, and it does not have enough rigidity to hold it on the outline position.Therefore, the present invention need add clot bond between annulus and film.Unless this film remains on the circle ring device by some means, piling up of annulus RLF device can not obtain, and this means that advantages more of the present invention will lose.
Unfortunately, plastic material and metallic material are difficult to combination, and be not different with combining of plastics with plastics or film as plastics.
Consider the RLF device tight connection that annulus should have a good surface to be used for and use subsequently, with film fastening be well another major reason.Model itself should have many shapes, or different characteristic, to help mounting process.
For example, model should have an area of heating, and it can help film and annulus to meet (having only seldom wrinkle usually) or cohere.
To annulus Heat forming film, can produce force fit by model, this helps cohering of film and annulus.
Material according to making film should provide release surface, to guarantee that film does not stick on the model.In addition, release surface should have suitable material or shape.In application more of the present invention, on the release surface, polytetrafluoroethylene (Teflon is arranged perhaps
TM), silastic material is perhaps arranged, it has heat conductivity preferably.
Model can also provide a kind of means, and whereby, film can be cut moulding.And can reach in many ways.
For example, around the annulus that film stretches out, cutter can be arranged.Cut film subsequently and shrink, no matter mechanical means is provided or passes through method of heating, film is coupled on the annulus.
In one embodiment, model is hot drift, and a sharp outer edge is arranged.Blade is used to cut film, and hot surface can help film is met on the annulus.If model moving enough soon on the RLF device, rapid movement just may be finished the needed cutting of film and meet so.
In another embodiment, for model provides an external blade, it has a cutting edge.This external blade is installed by this way, promptly can be cut after film meets preceding or meets as required.
In some embodiments of the invention, film is met on the annulus, pass through a vacuum chamber at this this device by a traditional vacuum film covering method.
Clot bond can be any material that film can be remained on the annulus.
In one embodiment of the invention, clot bond can be layered on the annulus before film is placed on the annulus.Certainly this is a logical embodiment of the present invention's row, and mounting process has increased a step really like this.As can seeing, compare the present invention with the thick film encapsulating method and eliminated many unnecessary steps.Therefore, in an embodiment of the present invention, should be noted that and avoid some additional steps as far as possible, to guarantee the efficient of this technology.
Therefore, in a preferred embodiment of the invention, film is used for combining with glue layer in structure, and gluing layer can make film and annulus cohere.
Should be understood that film can occur with any form of needed effect that can provide.In one embodiment, film has at least one gas trapping layer (to guarantee the life-span of jar content) and a glue layer.
In most preferred embodiment of the present invention, film is a five-layer structure, and it comprises a gas trapping layer, a structure enhancement Layer and a glue layer, and these three layers combine by two binding layers.
Increase Structural layer and can guarantee that film keeps it complete in seal process and operation subsequently, prepare to open the content that film wants to take out jar up to the customer.
Each layer can be formed with different materials.
The applicant has been found that membrane structure given below can very well play a role in the present invention:
| Layer | Material | Thickness |
| Structure | Ionomer | 65 microns |
| In conjunction with | The | 5 microns |
| Gas stops | EVOH32-44% ethene | 10 microns |
| In conjunction with | The | 5 microns |
| Clot bond | Ethene-vinyl acetate copolymer (EVA) 28 | 15 microns |
What provide above is an example of preferred film, is understood that and can uses other thickness and composition.Five layers is not essential requirement in addition, can use other the number of plies according to applicable cases of the present invention.
Other material that is used for each layer provides as follows:
| Layer | Material |
| Structure | Polyethylene, nylon, EVOH |
| In conjunction with | The bond material of any standard |
| Gas stops | With the mutual EVOH of ethylene component, nylon, high density polyethylene (HDPE), Vingon |
By using heat and/or pressure, the EVA clot bond can stick to film on the metal at an easy rate.
After the RLF device has just formed or in the jar installation process, should join the RLF device to sealed compound.Sealed compound can be any suitable compound, in one embodiment, is rubber.
Can think that the present invention can use less sealed compound.This is possible, because compare with aluminium or thick film, thin film has flexibility.
A less advantage of sealed compound is that RLF device productive costs is low.
Another less advantage of sealed compound is when annulus is connected on the tank body, to have less combination of compounds in linking circle front.
Know that in the present invention, the amount that is used for annulus outside plastic sheeting is compared still less than aluminium foil technology." amount of film " can represent with volume-be face area multiply by thickness.
Particularly, the applicant has been found that to compare with aluminium foil needs less plastic material.If use too many plastic material, when jar used, film can be sheared slippage from the outside of annulus.Can cause film externally to seal like this and form volume and form " loose linking ".Such linking can not provide better seal, and seems concerning the customer and can not accept.
Sometimes, only can not fully determine the whether contaminated or cheating of jar by the content of transparent membrane visual inspection jar.For example, have a microcosmic leak, make air admission in jar.Airborne oxygen makes the content degradation of jar make them be not suitable for consumption.Yet, the variation that this degradation may cause the physical change of jar content or be not easy to be seen by the customer.In addition, the saboteur can by syringe with injection of chemicals in jar.
In addition, the somebody may practise fraud to the content of jar, and does not provide the demonstration of directly seeing to content.For example, under the upper surface of powder, foreign matter is arranged.
According to another aspect of the present invention, this provide a kind of can the leak free container, this container comprises the visible indicator of at least one parameter in container.
With reference to so far, should have an identical form with previously described according to the container of this specification sheets manufacturing.
Sight indicator can be converted to non-visual parameters visible any indicator for any.
These parameters comprise but are not that restriction is as follows:
● basicity/acidity
● all gases
● chemical substance
● toxin
● pressure
● electromagnetic radiation
● moisture and steam
With reference to so far, the parameter of this specification sheets is a gas.
In one embodiment of the invention, indicator can detect the increase of oxygen level.If the content of jar is packaged in the rotten gas of low oxygen content, usually this situation can appear.If crackle appears in the sealing that jar is complete, enter the oxygen of jar and atmosphere and can be instructed to agent and detect.
In another embodiment, indicator can detect carbon-dioxide residual quantity.Usually have higher carbon dioxide content in the rotten gas, and in the air, carbon-dioxide content is 0.03%.Therefore, gas on every side enters jar (it is packed usually) leak free crackle and will dilute concentration of carbon dioxide in the jar under vacuum.Carbon dioxide in the jar can just be overflowed by the sealing in crack in addition.
Sometimes rotten itself can the generation of product variously can be instructed to the detected gas of agent.
In certain embodiments, sight indicator is installed in the inwall of jar and can sees through transparent sealing and sees.
In a preferred embodiment of the invention, in fact indicator merges in the film of sealing jar.
Here it is preferred embodiment because the packing indicator is the part of existing packaging step, rather than reduces the additional step of work efficiency.
The character of sight indicator can be any suitable form.For example, sight indicator can only change color.In other embodiments, indicator can become opaque or transparent.In other application, the intensity of indicator color can change.
The present invention uses be used to detect carbon-dioxide suitable indicator can be for having the anionic salt of indicator, and organic season of lipophilic cation.
Suitable indicator cation can be azo dyes (comprising orange alpha-naphthol), nitrophenolic dye (comprising m-nitrophenol and paranitrophenol), phthalein dye (comprising alpha-Naphthol phthaleins and orthoresol phthaleins), sulphur phenolphthalein class dyestuff (comprises m-cresol purple, metacresol is red, bromothymol blue and alpha-Naphthol sulphur phenolphthalein), kiton colors (comprising rosolic acid) and indophenol dye (comprising indophenols and 1-naphthols base 2-sulfonic acid indophenols).
Suitable season, cationic example was:
Ammonium cation (comprises the benzyl trimethyl ammonium ion, tricaprylmethylammonium ion, three CEPRYL ylmethyl ammonium ions, the TBuA ion, tetrahexyl ammonium ion and four octyl ammonium ions) and phosphorus cation (comprising the tetraphenylphosphonium ion, trioctylphosphine phosphonium ion and cetyl tributyl phosphonium ion).Preferred quaternary ammonium cation is the TBuA ion.
These indicator have carried out very detailed discussion in International Patent Application PCT/GB90/01501 number.
Suitable contain oxygen indicator and can be indophenols type dye, for example 2-6 dichloroindophenol.This dyestuff and deoxidation compound, the alcholye agent, the steam retention agent, bond, solvent and water mix can be used as ink.Very detailed discussion has been carried out in the use of this dyestuff in Japanese patent application JP06034619-A number.
An answer can be provided in some embodiments of the invention, indicator can with its relatively, provide information according to the customer that is designated as of indicator.
If indicator is the part of film, indicator can be a lot of different shapes, and for example, indicator can extrude jointly for strip shape and film.
In other embodiments, indicator can be the whole film of sealable tank.
In another embodiment, indicator can be discontinuous pattern on the film.
Indicator can form the part of multilayer film, each of film layer preferably should make container gas be penetrated into indicator easily, to produce appreciable variation.Film preferably also assembles, so that the skin of film can not allow air penetration to arrive indicator.
Indicator may increase an additional thickness to film, and it may influence sealing technology.
In order to adapt to this situation, can do some improvement (for example, changing the elasticity that is connected volume) to sealing technology, can think that this improvement can mark by making the indicator that is present in the film be discontinuous mark.These marks on the film are represented with the RLF device, so that make pure film (not having indicator) be positioned at diaphragm seal to the position of annulus.
Can see that the present invention had compared many advantages with former technology.
Provide an effective method to seal jar at this with transparent membrane.Whether whether can make the customer can say the content of jar at a glance so fresh and/or contaminated.
Can use thin film, it can cut easily and enter in the jar and do not produce sharp limit.
Some fragments of film that may drop into the content of jar are not produce chemical reaction, do not have detrimental effect though may cause making it to pass human body, do not resemble the film fragments of normally used jar.
It is an important advantage that a kind of indicator that can make the customer understand jar content freshness can be provided.
At last, the present invention can be used in the actv. processing technology.
The cutline of accompanying drawing
Others of the present invention will become clear by description with reference to the accompanying drawings subsequently, only describe to provide by example, wherein:

Implement best mode of the present invention
Fig. 1 shows RLF device commonly used, and it is briefly represented with arrow 1.
Device 1 comprises an annulus of briefly representing with arrow 2, lid 3 and aluminium foil form film 4.
Annulus 2 has three main portions.First 5 is a flange or passage, above aluminium foil is crushed on.Flange 5 folds and is crimped onto on the canister wall, and RLF device 1 is sealed on the jar 31.This is clearly show that in Fig. 4.
The centre portion 6 of annulus provides a space between annulus 2 and lid 3, it can make the people easily lid 3 be taken off from jar.
3 supporting roles of 7 pairs of lids of the third part of annulus.
The character of aluminium foil 4 is that it can be pressed into 2 one-tenth needed shapes of annulus.This can see from the flat that is compressed against aluminium foil 4 on the centre portion 6.Should be noted that aluminium foil 4 almost extends around flange 5.
Fig. 2 shows a RLF device according to one embodiment of the present of invention, and it is briefly represented with arrow 11.
In this embodiment, the annulus 2 of annulus 12 and lid 13 and existing technology is identical with lid 3 shapes.
With annulus 12 bonded assembly films 14 be multilayer plastic film, this film is a previously described type in the patent specification.
Compare with the RLF device of prior art, among the present invention, the amount of the plastic material in the flange 15 of annulus 12 is crucial.Too many plastic material 14 can cause that film externally seals 30 places wrinkling (this clearly show that) in Fig. 4.This wrinkle can cause empty linking, thereby causes that leak tightness is bad.
If the film that uses very little, possible film can not provide desired seal.
In one embodiment of the invention, the flat surfaces of flange 15 is 3.32 micron number magnitudes.The scope that the limit that has been found that plastic material 14 can be installed in flange 15 at the edge of flat to the centre of about flat.This is shown in Figure 2 and can avoid problem discussed above.
Existing apparatus shown in Fig. 1 is expressed the part of aluminium foil 4, and this partial parallel is in the flat 6 of annulus.When the thing of jar dress needed application of vacuum, this feature normally needed.
Similarly the amount of moulding is the scope of jar builder consideration, and reduces the space that produces between annulus, lid and the film by the amount of regulating moulding.Can not reduce the space and may cause difficulty in vacuum, because may be abundant at the amount of air that the space comprised, pressure makes lid 8 partly or entirely can not mesh with annulus 2.
Employed plastic sheeting is regulated by content and employed filling process that the jar builder will adorn according to jar equally.Film will with Fig. 2 in zone 16 identical modes cover this zone.
Fig. 2 does not illustrate the parallel zone between above-described 16 and 14, and in this form, annulus, lid and paper tinsel device will be used to gasless product.
Fig. 3 has described a kind of method, and film 14 can be connected on the annulus cover means of representing with arrow 11 by this method.
The length of film 14 covers annulus 12 and lid 13.The heated model 20 that has outside cutting sheath 21 is put on the film 14.The installation of sheath 21 and model 20 makes film 14 be cut in flakes before heating model 20 is pushed into groove 15 with film 14.
The effect of heating model 15 is that the gluing layer of film 14 is sticked to film 14 on the annulus 12.
Although film 14 is in the cutting of the outside of annulus 12, model is to be placed in the groove 15 in the permissible range that the outside cutting edge of film 14 is discussed in front the benefit that film echos on annulus/cover means.
After the moulding of RLF device, packing element (not shown) be placed on film 14 in the groove 15 above.
Subsequently final RLF device is deposited, up to being applied to final packaging technology.
Fig. 4 has described and how arrow 11 represented RLF devices commonly used has been fixed on the jar 31.Can see that paper tinsel 14 folds on the wall of flange 15 and jar 31, form a sealing, it is totally with arrow 30 expressions.
Fig. 5 is the top view that removes the jar 31 of lid, shows may arranging of film 14 and indicator 32,33 and 34.
In this embodiment, indicator 32,33 and 34 extrudes on film 14.Different parameters changes colour in the jar 31 that each indicator is sensed according to them.For example, indicator 32 can detect steam, and indicator 33 can detect CO2, and indicator 34 can detect O2.
Various aspects of the present invention only are described by example, but only should be understood that otherwise the scope that departs from appended claims can be improved and increase.
