Description
Invention field
The present invention relates to a kind of bag that is used for airtight preservation, this bag especially can be used for the airtight preservation of food, and is used for during cooking blanketing gas and liquid.More particularly, the present invention relates to a kind of bag, this bag comprises that at least one has the composite film material that prevents to be not intended to bonding pressure sensitive adhesive, perhaps comprise a film with at least a portion of forming by this composite film material, when it is exerted pressure, but be sealed in described adhesives release property, for example on another part of same film or the different films, form the inside of bag.
Background of invention
The container that is used for food preservation is well-known, and many kinds of forms are arranged, for example be equipped with the plastic casing of the different shape of deformable lid, as U.S. Tupperware Company sell with " TUPPERWARE " brand name those, with three face sealings, one side is the plastic bag of the opening of zipper form reclosable, as those preservation bags of selling with " ZIPLOC " brand name of U.S. S.C.Johnson Company and Japanese Asahi KaseiCompany.
The food preservation bag that another kind of customer generally uses is the polyethylene " storage bag " that gets a good review, and they are provided free by numerous food product grocery store and food products market.This class bag is also sold with UBE Kitchen Bags trade name by Japanese UBE FilmCompany (Onoda City, Yamaguchi Prefecture).This class bag is generally by directly fastening the free terminal of bag mutually, perhaps seals by using certain type metal or plastics to fasten thing.But the customer is frequent this class bag of blowing-by before they are put into refrigerator.
In addition, the various membrane materials that adhere to plate or other vessel surface by static also were used for food preservation in the past.The membrane material of these types provides with the package form usually, catches the free edge of film to be expanded to Len req by the user, and usefulness is deposited the subsidiary blade cuts in the packing of this volume then; Film with institute's Cutting Length is placed on the food of storage again, and adheres to by static on the surface of the plate that wherein is placed with food or container.This class film also can be directly used in packing or preserved food products; In these cases, be different from the adhesion to plate or other container, packing is that self adheres to.The embodiment of this class commercial membrane is sell with " SARAN WRAP " brand name and those films with the sale of " KRE WRAP " brand name KurehaKagaku Company of Asahi Kasei Company.The two is Japanese firm.
But the preservation bag and the film of this class routine are not immaculate.Common problem is its aeroseal and accordingly can not be fresh-keeping.For consumers, the comfort feature of use also is a problem.The film of rolling is difficult to control and uses, because they often cling prematurely, and usually is difficult to find out the free edge of film.As for preformed preservation bag, be difficult to firmly and the zipper end of sealing bag fully; Because opening is less relatively, also is difficult to and treats that preserve foods puts into bag.
Known use be called can steam the bag flexible pouch or capsule heat various food prepared therefroms again.For example can buy in the sealed plastic bag of packing into, be suitable for heating again some edible food prepared therefrom of back.Sealing bag is put into boiling water, and the heat of boiling water heats food again, and boiling water can not infiltrate in the bag.The user only need cut bag open then, takes out food.The common embodiment of this series products has, for example Japanese HouseShokuhin, S﹠amp; The curry food of B Shokuhin and Ajinomoto Companies.
Yet, can adopt this mode pack and again the heating food variety be limited.In addition, this class can steam the bag can not be used for actual culinary art fresh provisions; They only can be used for heating again and have processed the food of crossing with anti-corrosion treatment.
General food preservation bag discussed above both had been unsuitable in hot water heat preservation food again, also was unsuitable for cooking fresh provisions, because when sealing or during heating or culinary art again, do not have a kind of practical approach to can be used to guarantee the sealing of air and liquid.In addition, this class bag may not have heat that tolerance boiling water heat or micro-wave oven produce and the stay-in-grade material character.Even suppose this class material self be air seal or hydraulic seal, sealing or to seal the practical approach of this class bag more also very limited.
Therefore, still exist as can be seen and be used for airtight food preservation and the demand of the sack class container on air-tightness or the close property of liquid leak free convenient multi-purpose way during fresh provisions culinary art a kind of.Have whole advantage of the present invention and benefit without any prior art.

A preferred scheme of bag of the present invention is comprised of at least two overlapping membrane materials, and described membrane material has at least that its edge of overlapping is permanent seal. For example, in the embodiment of the bag 10 shown in the accompanying drawing 1a-1c, overlapping membrane material 20 and 30 is along at least one overlapping edge permanent seal. For example, first film 20 has edge 22,24,26,28. Second film 30 has edge 32,34,36 and 38. In this embodiment, having a pair of overlapping edge at least is permanent seal, for example the edge in the accompanying drawing 1a embodiment 22 and edge 32, edge 24 and edge 34, edge 26 and edge 36 or edge 28 and edge 38; Edge 23 in the accompanying drawing 1c embodiment can be permanent seal with edge 37 or edge 29 with edge 39 with edge 33, edge 27. For example, can shown in the reference number 13 among the reference number 12a among accompanying drawing 1a and the 1c and 12b and the accompanying drawing 1b, form permanent seal.
Should be clear, the permanent seal part at edge needn't extend to the length of whole overlapping edge, and is such in the preferred embodiment as shown in Figure 1. Can carry out permanent seal to the overlapping edge of any Len req in any part.
" permanent seal " used herein referred between the operating period of bag 10, and these edges are not expected to be opened by the consumer; They are can not the sealing of release property ground. Can use the known any method of this field professional, heated sealant for example forms the permanent seal part of the overlapping edge of bag of the present invention.
If bag is square or rectangular shown in accompanying drawing 1a, it is desirable to two overlapping edge permanent seals, for example with the edge 36 of the edge 26 of first film 20 and second film 30 along permanent seal line 12a permanent seal; And with the edge 38 of the edge 28 of first film 20 and second film 30 along permanent seal line 12a permanent seal. Accompanying drawing 1c shows the bag of the accompanying drawing 1a that is in a fully open position, and the below will describe its advantage in further detail.
Again mention accompanying drawing 1a, in the preferred embodiment with two permanent seal edges, the edge of two permanent seals is preferably adjacent, two crossing edges of rectangle or square bag for example, and they are perpendicular to one another, such as edge 26,36 and 28,38. But, also can select two relative non-crossing edges, for example 22,32 and 26,36; Perhaps 24,34 and 28,38 as the permanent seal edge.
Accompanying drawing 1b shows another embodiment, and wherein bag is 10 triangular in shape, its have a pair of overlapping edge 23,33 along permanent seal line 13 by permanent seal. Moreover, should be clear, the permanent seal at edge part needn't extend to the whole length of overlapping edge, and can carry out permanent seal to the overlapping edge of any Len req in any part.
Should be clear, the present invention is limited to any given shape or configuration with bag 10 or film 20,30. In addition, the size of film needn't be identical or similar, and its shape also needn't be identical. And the preferred embodiments of the invention are not limited to comprise the bag of one or two membrane material. Comprise the bag of two above films also within the scope of the invention.
Again mention accompanying drawing 1a-c, at least one in the film 20,30 is to have the composite membrane that prevents from being not intended to bonding contact adhesive. Phrase " bonding unintentionally " refers to the film of adhesive can permanently not be bonded in target surface, such as another part or any other surface of another film, same film before the user of bag is by activated adhesive that film is exerted pressure. When it is exerted pressure, but with the film release property of adhesive be sealed in the periphery (showing in the accompanying drawing 1, referring to accompanying drawing 2c and 7) that another film or the another part of himself form sealing. Be described in more detail below composite film material itself.
Therefore, when the consumer exerts pressure to film, form the periphery of sealing in selected position. Can select any position, should notice that simultaneously the periphery that seals needn't be consistent with the edge of membrane material.
If film 70 is square or rectangulars, can be at or about free edge arranged side by side (for example, 82 and 92,84 and 94 and 86 and 96, shown in accompanying drawing 2b) but form the release property hermetic unit of seal perimeter, make bag have a maximum internal area. But as implied above, the position of wanting of can in officely what is the need for forms seal perimeter.
Another preferred embodiment of bag of the present invention (not showing in the accompanying drawings) is similar to the embodiment shown in the accompanying drawing 1a-c; But in this preferred embodiment, there are not the edge of permanent seal or the edge of part permanent seal. In this preferred embodiment, at least one film is composite film material as described below, and when they are exerted pressure, but with the film release property of adhesive be sealed in another film and form seal perimeter. The sealing periphery forms the inside of bag.
Another preferred embodiment of bag of the present invention is shown in accompanying drawing 2a-b. In this embodiment, as described in detail below, bag 10 comprises single film 70. Film 70 has first 80, second portion 90 and is usually located at engaging zones 75 between the first and second parts 80,90. In accompanying drawing 2a, engaging zones 75 is represented by dotted lines, and does not have zone or the position of accurately determining to indicate it. In addition, it can be divided into arbitrarily the separately zone of size and shape with first 80 and second portion 90; The size of these parts or shape needn't be identical or roughly the same.
Should notice that the rectangle film 70 shown in the accompanying drawing 2a is not a kind of restricted shape. The same with the preferred embodiment shown in the accompanying drawing 1, the film 70 of any shape all within the scope of the present invention, for example circle, ellipse, triangle, amorphous, decorative shape.
First is limited by the free edge of at least one section first.In the embodiment shown in the accompanying drawing 2a, first's free edge is by reference number 82,84 and 86 indications.Second portion is limited by the free edge of at least one section second portion.The second portion free edge is by reference number 92,94 and 96 indications.Moreover, should notice that this scheme is not limited to have the free edge of given number.For example,, one section continuous first's free edge will be arranged then if film 70 is oval, rather than three sections shown in the accompanying drawing 2a.
In a preferred embodiment, at least one in first 80 or the second portion 90 prevents that by having the composite material that is not intended to bonding pressure sensitive adhesive from forming.In a further preferred embodiment, first 80 and second portion 90 all prevent that by having the composite material that is not intended to bonding pressure sensitive adhesive from forming.In a further preferred embodiment, engaging zones 75 also prevents that by having the composite material that is not intended to bonding pressure sensitive adhesive from forming.
In another preferred scheme, film is to have one whole the composite material film that prevents to be not intended to bonding pressure sensitive adhesive; In other words, first 80, second portion 90 and engaging zones 75 are present on the same monolithic film membrane as the specific region, form bag thus.
By the film 70 following bags 10 that form, referring to accompanying drawing 2b.First 80 in engaging zones 75 or its folded around, so is covered on the second portion 90 usually.By forming seal perimeter 85 to exerting pressure facing to one in the first of another part or the second portion in desired location.Therefore, the inside of bag 10 forms in seal perimeter 85.If consumer wants, the formation of encapsulation boundary can be irrelevant fully with engaging zones 75, and example as shown in Figure 7.Perhaps, shown in accompanying drawing 2c, the inside of bag also can be included in the engaging zones and encapsulation boundary 85 in.
In another preferred embodiment of the bag of accompanying drawing 2 shown types, as mentioned above and to be similar to the mode shown in the accompanying drawing 1a, it is desirable to provide at least one section in first or the second portion free edge with band opening cue mark.This opening cue mark preferably forms visual contrast with first or the second portion free edge that other does not have the opening cue mark.
In above-mentioned each embodiment, in the embodiment that relevant accompanying drawing 1 is described, in the film 20 or 30 at least one, or film 70, or in the scheme that relevant accompanying drawing 2 is described, in first 80 or the second portion 90 at least one is made up of composite material, those materials of describing in for example following document: the US Patent the 5th of the Hamilton that on September 2nd, 1997 announced etc., 662, No. 758, " Composite Material Releasably Sealable to A Target Surface WhenPressed Thereagainst and Method of Making " (but when it is exerted pressure, being sealed in composite material of target surface and preparation method thereof) release property; The US Patent the 5th of the Hamilton that on February 16th, 1999 announced etc., 871, No. 607, " Material Having A SubstanceProtected By Deformable Standoffs And Method of Making " (having material of the material of using the deformable balanced protection and preparation method thereof); The US Patent the 5th of the McGuire that on October 12nd, 1999 announced etc., 965, No. 235, " Three-Dimensional; Amorphous-Patterned, Nesting-Resistant Sheet Materials and Methodand Apparatus for Making Same " (three-dimensional, amorphous pattern, anti-intussusception membraneous material and preparation method thereof and device); US Patent the 5th with the Hamilton that announced on October 19th, 1999 etc., 968, No. 633, " Selectively-Activatible Sheet Material ForDispensing And Dispersing a Substance Onto A Target Surface " (be used to provide and deliver and material is distributed to the membraneous material that the alternative of target surface activates).
This composite material is that this adhesives is used for being sealed in target surface releasedly and preventing to be bonded in too early target surface with the flexible membrane of pressure sensitive adhesive dressing.Especially, this composite material is to have the outstanding flexible membrane that forms in binder side.Described giving prominence to is used to separate pressure sensitive adhesive and target surface, until film is exerted pressure.According to the present invention, " target surface " is another film 20 or 30 in the embodiment shown in the accompanying drawing 1, perhaps another part of the same film 70 in the embodiment shown in the accompanying drawing 2 at this.
Though disclose composite material of the present invention in the top referenced patent, the present invention still succinctly describes once more comprehensively.An embodiment of complex film is represented with 100 as shown in Figure 3 usually.Complex film 100 generally comprises has outstanding 140 flexible membrane 120 and the pressure sensitive adhesive layer 160 between outstanding 140.In the scheme of the film shown in the accompanying drawing 3 100, outstanding 140 by butt or outermost end 180 are dome-shaped taper shapes.Outstanding 140 is equally spaced equilateral triangles, and all is outstanding all towards identical direction.The spacing of their Center-to-Centers is approximately two outstanding diameters.Outstanding 140 height preferably is lower than its diameter, so when they subsided, they subsided along the axle that is substantially perpendicular to film 120 planes.This mode of subsiding has avoided outstanding 140 to fold and hinder contacting of adhesives and target surface.
Accompanying drawing 4 display-object surfaces 200, according to the present invention, the surface 200 is another films, this film comprise bag 10 or with the film that forms this bag be another part of same film.This film and pressure-sensitive adhesive layer 160 are highlighted 140 outermost end 180 separations.Accompanying drawing 5 is presented under the pressure that non-adhesive side to flexible membrane 120 applies strength F as shown, and after outstanding 140 self partial inversion, target surface 200 contacts with pressure-sensitive adhesive layer 160.
In the embodiment of the film 100 shown in the accompanying drawing 3 to 5, the base diameter of cone outstanding 140 is about 0.015 inch (0.381 a millimeter) to about 0.03 inch (0.762 millimeter).Their Center-to-Center spacing is about 0.03 inch (0.762 a millimeter) to about 0.06 inch (1.524 millimeters), and outstanding height is about 0.004 inch (0.102 a millimeter) to about 0.012 inch (0.305 millimeter).Membrane material can be made by resin of the same race or its compound.Single or multiple lift in the membrane structure can be coextrusion, extrude that film, lamination or obtain in conjunction with other any means known.The determinant attribute of membrane material is that its deformable produces outstanding and depression.Useful resin comprises polyethylene, polypropylene, PET, PVC, PVDC, latex structures thing, nylon etc.Preferred membrane material is about 0.01 to about 0.02 millimeter, is more preferably about 0.012 polyethylene to about 0.015 millimeter nominal thickness.Preferred membrane material is the 100% HDPE film that derives from U.S. Tredegar Co., thick about 0.012 millimeter.This class film also can derive from U.S. Exxon Co..
Pressure-sensitive adhesive layer 160 preferably thickness is about 0.025 millimeter hot-melt adhesive.This class hot-melt adhesive is applicable to the present invention, for example derive from U.S. Findley Co. as specification be ATOFindley 2630.07,2630.08 and 2630.09 those and what derive from Minn. H.B.Fuller Co. is those of HB Fuller HL-2115X, HB Fuller HL 1711-XZP and HB Fuller HL 1717-X as specification.Perhaps, other adhesives that comprises latex also can be used for bonding coat 160.
Optimize outstanding size and spacing, so that the continuous bonding approach of hydraulic seal to be provided, but do not form the film that is easy to extend.The film that extends produces the residual strength parallel with the adhesives contact level, and this strength causes weak bonding connection cracking.
Complex film of the present invention is more preferably three-dimensional composite film material, and this material has the anti-foldable layer performance of intussusception (described in No. the 5th, 965,235, the US Patent of above mentioned McGuire etc.) each other.
For the advantage of this anti-intussusception is provided, give prominence to a plurality of different two-dimentional geometrical shape that forms amorphous pattern in a side of composite film material; Form corresponding to outstanding a plurality of separations, three-dimensional hollow depression in a relative side, like this outstanding is hollow.Implication when the term " unbodied " that the present invention uses generally uses usually with it is identical, and promptly it constitutes the pattern that cell list reveals the tissue, rule or the direction that are difficult for discovering.In this pattern, the direction that the unit is adjacent the unit does not have foreseeable relation with the direction and the arrangement of arranging for ensuing continuous unit on the limit.
In preferred amorphous pattern, outstanding size, shape, grid direction and preferably inconsistent with the spacing at adjacent outstanding center.Accompanying drawing 6 is planar views of representative three-dimensional of the present invention, anti-intussusception membrane material 200.Outstanding with reference number 240 expressions, spacing is with reference number 220 expressions.Accompanying drawing 6 is also indicated size A.A represents the width of spacing 220.This width measurements be the distance of perpendicular between the substantially parallel wall of adjacent protruding bottom.In a preferred embodiment, the width of all outstanding spacings 220 is preferably constant basically.
In the amorphous pattern of arranging, use to have the structure that the polygon that limits the limit number is better than adopting circle or approaching circle with occluding relation.Some patterns, for example with the pattern of circle arrangement, for the non-circular area between the adjacent circle, but the amount of circle footprint area is restricted.More particularly, though adjacent therein circle under the pattern of point of contact contact, a certain amount of quilt " besieging " gap is located still to exist in " corner " between the point of contact continuously.Therefore, even circular amorphous pattern also is subjected to how little non-circular area being designed into the restriction in the structure.On the contrary, can design and have the interlock polygon (that is, not having curved side) that limits the limit number,, and in a limited sense, can so arrange so that adjacent polygonal adjacent edge can be along its total length contact so that it closely is arranged in together.Like this, between the angle, there is not the free clearance of " besieging ", referring to accompanying drawing 6.As US Patent the 5th, 965, described in No. 235, amorphous pattern of the present invention has the randomness of control degree on the statistics.
It is believed that single outstanding 3D shape works in single outstanding physical property of decision and whole grid character.It is believed that the present invention is highly useful for outstanding use interlock polygon basic schema.This polygon Mode preferably includes the convex polygon of interlock, and each polygon has the limit of the substantial linear that limits quantity, and adjacent polygonal relative edge is parallel basically.But should be clear, in fact any 3D shape can form outstanding.
For make outstanding between hollow volume minimize, reduce the amount of the adhesives between outstanding thus, the average headway of outstanding 240 Center-to-Centers preferably approximately is the diameter of two protruding bottoms or littler.Preferably, outstanding height is less than its diameter, like this when they be out of shapes, their take place basically along spool counter-rotating and/or overwhelm distortion, described is substantially perpendicular to material plane.Should outstanding shape make outstandingly can on the direction parallel, not fold, so that outstandingly can not hinder contacting of adhesives and target surface in caving between outstanding with material plane with deformation pattern.
Preferred adhesive of the present invention is the hot-melt pressure sensitive adhesive of about 0.025 millimeters thick.This class hotmelt is applicable to the present invention, for example derive from U.S. Findley Co. as specification be ATOFindley 2630.07,2630.08 and 2630.09 those and what derive from Minn. H.B.Fuller Co. company is those of HB Fuller HL-2115X, HB Fuller HL 1711-XZP and HB Fuller HL 1717-X as specification.Perhaps, other adhesives that comprises latex also can be used for bonding coat 160.
Membrane material can be made by homopolymerization resin or its compound.Single or multiple lift in the membrane structure can be coextrusion, extruding coating, lamination or obtain in conjunction with other any means known.The determinant attribute of membrane material is that its deformable produces outstanding and depression.Useful resin of the present invention comprises polyethylene, polypropylene, PET, PVC, PVDC, latex structures thing, nylon etc.The preferable material specification is about 0.0025 millimeter to about 0.25 millimeter.Preferred membrane material is the 100% HDPE film that derives from U.S. Tredegar Co., thick about 0.012 millimeter.This class film also can derive from U.S. Exxon Co..Can pass through mechanical stamping, heating in vacuum moulding, hydroforming or its combined method moulding, and by other known method moulding of this area professional.
Preferably present amorphous pattern though it should be noted that the whole surface of film, in some cases, it also is desirable that the part surface of this class film presents this pattern.For example, the part of film can present the highlight mode of certain rule, perhaps in fact can be not outstanding, be rendered as general plane like this.
In addition, the designer can be with the non-amorphous pattern of regularity or basic not outstanding " blank zone territory or separate amorphous domain in conjunction with this dual mode.Also can further customize the shape and the size of amorphous domain.
As previously described, in embodiment shown in the accompanying drawing 1, comprise at least one in bag 10 the film 20 or 30, perhaps the part for the film of the embodiment made from single film is aforesaid composite film material.Other membraneous material or its part can be same or similar composite materials; Perhaps, other film or its part can the compound membraneous materials of right and wrong, and described non-compound membraneous material is the known any conventional membrane material of this field professional, for example high density polyethylene (HDPE) or low density polyethylene (LDPE).In embodiment shown in the accompanying drawing 2, at least a portion that forms the film 70 of bag 10 is aforesaid composite film material.Therefore, the user of bag 10 can seal this bag releasedly by following process: exerted pressure in the position of any other hope simply, activate the adhesives of laminated film, make it closely be sealed in aimed thin film or target part in seal perimeter.
For having aesthstic attractive force, it also is desirable providing ornamental stamp to membraneous material of the present invention or its any part or many parts.This stamp can provide with any pattern, color, pattern, design etc.
For example, the food 40 of accompanying drawing 7 display packings in preferred embodiment bag 10, wherein seal perimeter 45 by the user generally in the formation of on " S1 " and " S2 " direction of the arrow mark of food periphery, exerting pressure.Bag 10 like this can be made up of any embodiment that the present invention describes.
Accompanying drawing 8 illustrates another embodiment that bag 10 is used.Promptly can divide several object storing district independently in a bag, no matter these stored articles are same types or dissimilar.Can be by form separate airtight or closed perimeter 45a-d that liquid is close around the independent article 50 at desired zone compacting film.Be that an independent bag is inner in each closed perimeter 45a-d.Perhaps, can bag be compressed simply to produce four according to the indication of arrow S1-S4 and be used for 4 sealed compartments of leak free.Bag 10 like this can be made up of any embodiment of the present invention.
Of course it is to be understood that that show in the accompanying drawing only is embodiment.Fig. 7 and 8 is not restrictive, can use the different embodiments of bag of the present invention with multitude of different ways, and all within the scope of the present invention.
Accompanying drawing 1c has shown the bag of the accompanying drawing 1a that is in full open position, and it illustrates one of advantage of the present invention.Shown in accompanying drawing 1c, because this bag has two impermanency leak free overlapping edges, therefore bag 10 has the bigger zone of inserting and take out.For example, the representative dimensions of bag of the present invention is about 29.2 to 30.0 centimetres and multiply by 30.0 centimetres.For the bag with such size, inserting/take out aperture area is about 1040 sq cms, and this is to calculate by the open area being defined as complete circle.
Usually be convenient to other non-limiting size that family uses and comprise that about 15.0 centimetres multiply by about 15.0 centimetres and about 60.0 centimetres and multiply by about 60.0 centimetres.
On the contrary, for example zipper form bag or storage bag can not provide such advantage only to have a conventional bag that can be used for inserting and taking out.In commercially available zipper form bag, opening in fact may be than the bag narrow dimension of reality, and this is because must be used in conjunction with the zone of zipper material and sealing institute extremely.Therefore, for big or article in irregular shape, such zipper form bag may be inconvenience or impossible.For example, commercially available ZIPLOC vegetables preservation bag has about 26.8 centimetres of sizes that multiply by 27.9 centimetres.Yet it is inserted/takes out aperture area and only is about 223 sq cms, and this is to calculate by the open area being defined as complete circle.
Therefore as can be seen, when being in full open position, the sack size of the open area of the embodiment of bag shown in accompanying drawing 1a of the present invention and the 1c is than other commercially available preservation bag size about at least 50% of storage bag and zippered bag for example.
Though people like square or rectangular to give bigger utilized interior zone, and may have two impermanent leak free edges being convenient to insert and take out, but also can be other shape and they all are included in the scope of the present invention, oval or the circular bag that is made of the described composite material of one deck at least for example, it has the open area of the releasably sealable that is used to put into and take out food.
In addition, do not have the bag and same convenient use of the bag at the edge with permanent seal at permanent seal edge, the former is more convenient for using sometimes.The type that is suitable for most the bag of application target depends on the purposes of needs, will put into the size and the shape of the article of bag, and user's hobby.
Therefore as can be seen, can easily will need preservation or food cooked to insert and take out in the bag 10 of the preferred embodiment of the invention, because this bag can hold the food of multiple different size and shape.
Except its wieldy advantage, bag of the present invention also has the fresh-keeping effect of improvement for preserved food.It is believed that this advantage is the super air-tightness that comes from bag of the present invention.In an embodiment of the present invention this advantage will be described in more detail.
