Description

Airtight container

Technical field

The present invention relates to container, relate in particular to the container of supplying drink for the customer.The present invention also is used in particular for the storage and the supply of soda and other fizz, but also can be used for the beverage or the content of other type.

Background technology

For many years, beverage supply merchant and container manufacturer are devoted to provide practical wide-mouth beverage supply container always, make clients cosily drink drink as use glass or other drinking container, are especially relating to soda for example during beer etc.Although this drinking container can provide very big advantage to beverage supply merchant, container manufacturer and customer etc., can the fine drinking container that satisfies these targets but still do not produce.Therefore, present bottle and the pop can beverage supply container of customer's main use still.This is that an important techniques difficult problem does not overcome because large container exists very, and does not design the practical plan that addresses the above problem as yet.The object of the present invention is to provide a kind of drinking container of practicality, this container can be large container (the present invention can also be applied to the container of other type, comprises for example bottle of those containers with narrow neck opening).

Previous someone once proposes to use the paper tinsel sealing to provide hermetic closed to such container.Multiple proposal has been described in WO2006/000773.It is that joint between paper tinsel sealing and container body has very high shearing strength value that use has in a plurality of problems that paper tinsel leak free closing means (but meaning that it is designed to green phase and container body is rotated and moves) exists one, therefore is difficult to promptly to apply shearing force by twisting action and destroys this joint at joint.

The present invention manages to provide a kind of container with closing means, and described closing means can be resisted elevated pressure in the container for example because the carbonic acid class of storage or contain the liquid of other gas and/or pressure that temperature build-up and/or shock loads cause raises.

The present invention also provides a kind of container, wherein between paper tinsel sealing and the container be bonded on when direction of operating reverses closing means easier to be destroyed.

Summary of the invention

A first aspect of the present invention provides a kind of container with storage soda or other content, the removable closing means that it comprises the container body with the opening that limits axis and is used for closed described opening, thereby this closing means comprises and is suitable for joining to the paillon foil of this container with the closed described opening of air tight manner, this paillon foil also is connected to this closing means or matches with this closing means, make described closing means along open direction relatively the initial rotation of this container body or other move and twist by this way or be out of shape described paillon foil, thereby the further rotation of described closing means or other motion produce the peeling force that is applied to the joint between this paillon foil and this container.

This configuration is preferably allowed closing means in the initial rotation of opening on the direction, and can not destroy the joint between paillon foil and the container body.Yet this initial rotation moves closing means and axially leaves container body, thus when further rotating closing means, apply peeling force but not shearing force to described joint.The multiple mode that realizes above-mentioned purpose has been described.For example, this purpose can be moved by the lifting that the rotational transform of closing means is become act on paillon foil and be realized.

Closing means or lid are preferably paillon foil entity supporting are provided, for example it by restriction because the pressure in the container increases the deformation extent that causes and/or by strengthening the joint between paillon foil and the container.Lid is normally circular, thereby this lid can be placed on the periphery around the paillon foil of the periphery of opening, therefore helps to keep paillon foil to contact with container.In some cases; it is prominent owing to container inner pressure rouses to provide enough obstacles to limit paillon foil; but preferably this lid extends across whole paillon foil; with the especially distortion of paillon foil center of distortion of further obstruction paillon foil, but also the protection paillon foil prevent with may puncture paillon foil and/or slacken its integraty exterior object actual contact and be damaged.Therefore this lid is strengthened and/or keeps connecing between paillon foil and the container to merge into paillon foil providing and puncturing protection.

In a preferred embodiment, the downside at closing means is provided with jut to strengthen the joint between paillon foil and the container body.Jut can comprise the hole sealing, and its extruding paillon foil contacts with the inside face of container body.This also helps and form induction welding between them.

This lid can be made by a series of materials, and preferably for example polypropylene (PP), polyethylene (PE) or polyethylene terephthalate materials such as (PET) are made and can be made by injection moulding by plastics.

Preferably, this lid can releasably be fixed to container body by lid being firmly held in bayonet fitting on the container and/or screw thread (directly or pass through collar), and this lid can green phase rotates container body and removes from this container body.The preferred embodiments of the present invention have the closing means that covers at the collar following formula, and wherein this lid is fixed to container body by collar, thereby container body does not need to be provided with helicitic texture.The closing means on collar of covering of suitable form has been described in WO2006/000774, WO2007/091068 and WO 2008/012539.

Also preferably be provided with exhaust gear, the pressure in the container will covered and/or paillon foil can be released before removing fully.For example can when peeling off, container provide controlled exhaust at paillon foil.

Paillon foil preferably is attached to container around the periphery of opening by high-frequency heating.Preferably, paillon foil to container attached (though intensity is enough to bear the desired pressure level in the container) than a little less than attached between paillon foil and the lid, thereby removing when cover, paillon foil separates with container, but still maintenance is attached to and covers and remove with it.

Preferably, paillon foil is fixed to closing means, thus when closing means by when container body is removed, paillon foil is removed with closing means, thereby can a step open container.Paillon foil should be than its attached closing means that is attached to more firmly to container body, thereby when engaging between paillon foil and the container disconnected, it still kept being attached to closing means.Paillon foil can mechanical fixation or the closing means or be fused to closing means of being adhesively fixed.

Paillon foil mentioned in this article comprises the liquid-tight laminate, its be included as paillon foil provide intensity one or more layers and be used for that upper surface and/or lower surface with paillon foil be attached to another article one or more layers.This class paillon foil is widely used in other field.Under the situation that paillon foil is fixed by high-frequency heating, need conductive layer.This conductive layer is metal level normally, and aluminium lamination the most generally.Conductive layer is by being provided with one or more layers plastic coat, and polyethylene coating for example is when conductive layer is heated described coating fusing when paillon foil being joined to the article that keep being in contact with it.This class paillon foil can be engaged to glass and plastic product.Preferably, paillon foil is so constructed, and makes that it can be by preforming with the assembling that helps closing means and join the container body main body to.

Paillon foil preferably is fixed to container in the mode that can resist high internal pressure.Current application be to comprise laminated foil two-layer or multilayer aluminium, it can resist the pressure (as the pressure that may occur) up to 5-6 crust when carbonated beverage container runs into high temperature.As preventing that gas from overflowing, paillon foil also protects container can not enter gas, thereby helps prevent the beverage pollution and prevent that beverage is rotten.Use this paillon foil, drinking container can have some months resting period, for example four months or longer (time that needs usually as the beer sold in container and other soda)

In certain embodiments, paillon foil is configured to reduce the deflection under given internal pressure.This can realize by the suitable material of for example selecting to be used for laminated foil.Especially, if one deck of laminate then can use the crosswise lamination sheet in one direction such as more pliable and tougher on the vertical direction or more stretch, promptly wherein two such layers along different direction orientations (preferred vertical mutually).

When paillon foil is adhesively secured to when covering, the upper surface of preferred paillon foil constitutes (promptly not having plastic coat) by aluminium and helps form stronger joint.When paillon foil is fixed to when covering by mechanical fixation or welding, thereby wish in certain embodiments to use plastic coat to have different fusing points in the two sides of paillon foil.

Paillon foil also has the start showing function, if promptly paillon foil is intact, then allows customer's trusted products not be stolen or opens in advance or otherwise be exposed to external environment.Made by transparent material as operculum, this function is then further strengthened.

Container body usually by plastic material for example polyethylene terephthalate (PET) make or make by glass.The shape of container can be similar to traditional drinking container, for example is the stein of bottle or some other shape.

The opening of container body is wide-mouth formula opening preferably." wide-mouth formula opening " meaning be meant (at least on its most wide in range meaning) size be fit to people can be as use glass or similar drinking container the opening of beverage from container.That is to say, according to its most wide in range meaning, the wide-mouth formula opening of container (being suitable for a plurality of embodiment with wide-mouth formula opening of the present invention) generally makes container be suitable as drinking container, can drink the beverage (with generally not thinking that the traditional glass vial or the pop can of comfortable drinking container are opposite) of its supply from this container easily.In fact, this requirement is meant that the diameter of the wide-mouth formula opening of container generally needs 40mm at least, preferred 45mm at least, and more preferably 50mm.In addition, wide opening also allows customer's beverage difficulty, so the diameter of wide-mouth formula opening preferably is not more than 150mm, more preferably no more than 100mm, particularly is not more than 80mm.The particularly preferred diameter range of wide-mouth formula opening be 50mm to 80mm, the example of particularly preferred diameter comprises 53mm and 63mm.

The specific embodiment

Fig. 1 show comprise have by antelabium 1B around the container body 1 of wide-mouth formula opening 1A, be applied to the paper tinsel sealing 2 on the whole opening 1A and be and cover 3 and the closing means of collar 4 forms.

Paper tinsel sealing 2 for example is fixed to the top of antelabium 1B by induction soldering along the weld junction 2A shown in Figure 1A.Paper tinsel sealing 2 has such diameter, and promptly its antelabium 1B and part outside it that extends across container body 1 is folded back on himself, shown in Figure 1B subsequently.The revers turn part 2B that is the fold form of paillon foil then is fused to along the weld junction 2C that is positioned at weld junction 2A inner radial and covers on 3 the inside face.

Fig. 1 C shows at the cutaway view of container body 1 loam cake 3 during in make position.When direction (shown in arrow A 1) rotation is opened on lid 3 edges, cause and cover 3 relative collar 4 and container body 1 axial motions, shown in arrow A 2.The revers turn part 2B that is the fold form that should be appreciated that paillon foil 2 allows and covers 3 initial rotation, and can not destroy the junction surface 2A between paillon foil 2 and the container body 1.

When lid 3 risings (be actually and outwarded winding), the revers turn part 2B of paillon foil is tightened up, and therefore covers 3 further rotations and axial motion and by revers turn part 2B junction surface 2A is applied a peeling force, shown in Fig. 1 D.The peeling force that junction surface 2A is applied by revers turn part 2B has upwards and inside two components, and is as shown in arrow 3, thereby paillon foil 2 is peeled off from container lip 1B.

In case paillon foil 2 separates fully from container body 1, then it removes (this paillon foil still welding at the downside of container cover) with container cover 3

The danger that does not join the upper surface of the part that paillon foil extends for the revers turn part 2B with paillon foil on whole opening 1A minimizes, and the upper surface of paillon foil (in the position shown in Figure 1A) can comprise aluminium lamination.

Fig. 2 shows second embodiment, and it has container body 1, replaces the double-deck paillon foil 12 of inflection paillon foil, lid 13 and collar 14.

Paillon foil 12 comprises paillon foil 12A and following paillon foil 12B.Following paillon foil 12B is fused to the top of the antelabium 11A of container body along weld junction 12C.The lower surface of last paillon foil 12A is fused to down the upper surface (referring to Fig. 2 B) of paillon foil 12B along weld junction 12D around its periphery, and its upper surface is fused at the radially inner regional 12E of

weld junction

12C and 12D and covers 13 inside.

Therefore last paillon foil 12A and following paillon foil 12B only are bonded with each other around their periphery, for example are hollow annular tea bag form thereby form hollow pad.For the inside face that prevents paillon foil 12A and following paillon foil 12 is bonded with each other, these inside faces preferably form (except the weld junction 12D zone) by aluminium lamination.

When direction (shown in arrow A 1) rotation was opened on lid 12 edges, lid is rising (shown in arrow A 2) vertically.The core of last paillon foil 12A and following paillon foil 12B separates a little, shown in Fig. 2 C and Fig. 2 D.Last paillon foil 12A also can be distorted in this motion process of lid 13.Be deformed to a certain degree in case go up paillon foil 12A, it is tightened up and knit line 12C is applied a peeling force.This peeling force has component and radially inner component upwards, shown in arrow A 3 among Fig. 2 D.

Fig. 3 shows modification embodiment illustrated in fig. 2.In this example, following paillon foil 12B joins the inside (rather than the top of antelabium or outside) of container body antelabium 11A to.The downside of lid 13 also is provided with jut 13A, and when covering in make position, it provides the joint of reinforcement between following paillon foil 12B and container body 11 by the periphery that presses double-deck paillon foil.In this case, peeling force upwards and outwards act on down joint between paillon foil 12B and the container body 11, promptly the radial inner end in weld portion begins to peel off.Such another embodiment is described with reference to figure 8A to Fig. 8 F hereinafter.

Can expect other configuration, wherein a paper tinsel leak free part is allowed the initial rotation of lid, and can not destroy the knit line of paillon foil and container, thereby can peeling force be applied to this knit line by further rotatable cover subsequently.

Fig. 4 to Fig. 6 shows other embodiment, and wherein this initial motion is by the line of weakness in the paper tinsel sealing or tear and start structure and realize or promote.

As implied above, the paillon foil that uses can stand very high bursting pressure now.Such paillon foil intensity is very high, therefore is difficult to paillon foil is torn or torn, and starts structure (unless described paillon foil is cut or pierced through by sharp-pointed edge or sharp-pointed point) unless point of weakness is set in paillon foil or tears.

Embodiment shown in Figure 4 comprises container body 21, paper tinsel sealing 22, lid 23 and collar 24.Paillon foil 22 is fused to container lip 21A along weld junction 22A and is extended outside this antelabium, shown in Fig. 4 A.The sponson of paillon foil 22 is provided with one or more startup structures of tearing, and for example is the form of slit or otch 22B, and the upper surface 22A of paillon foil is fused to by the part and covers 23 inside by the fusion area 22C on the jut of paillon foil and near otch 22B.

In this case, when direction (shown in arrow A 1) rotation was opened on lid 23 edges, the part of covering 23 downsides that is fused to of paillon foil 22 was subjected to peripheral force, and it is applied to subsequently to tear and starts structure 22B, and paillon foil 22 begins distortion or tears thus, shown in Fig. 4 C.Because along with the rotation of lid 23, it also moves axially (arrow A 2), this part of paillon foil 22 is also mentioned from container 21, so paillon foil begins to peel off (shown in arrow A 3) from container 21.

Fig. 5 shows modification embodiment illustrated in fig. 4.In this example, paillon foil 22 is torn to start structure 22B and tear each that start structure near these and is provided with fusion area 22C and is used for paillon foil 22 joined to and covers 23 inside being provided with a plurality of (in the example that is illustrating being four) in the position that separates at interval around its periphery.

Fig. 6 shows another embodiment, and this embodiment is provided with line of weakness in paillon foil, initially unscrews motion with what allow lid, thereby can subsequently peeling force be applied to paillon foil.

This embodiment comprises container body 31, paillon foil 32, lid 33 and collar 34.Paillon foil 32 is provided with protrusion tab 32A upwards, and this protrusion tab is fixed to by local fusing district 32B and covers 33 inside.Paillon foil 32 also have radius be slightly less than container lip 31A radius circular line of weakness 32C and be positioned at tearing of protrusion tab 32A bottom and start structure 32D.Paillon foil 32 is welded to the upper surface of container lip 31A along weld junction 32E.

When lid 33 when opening direction (arrow A 1) and rotate, protrusion tab 32A circumferentially (and upwards) power of moving and be applied on it starts the tearing notch that structure 32D place begins to form paillon foil 22 tearing.This tearing notch extends internally, and arrives line of weakness 32C until it, and here tearing notch extends (shown in Fig. 6 C) along this line of weakness.Therefore peel off from container the outer ring of paillon foil 32, and separated until whole paillon foil 32, paillon foil is removed (still be attached at and cover 33 inside) thereupon, shown in the arrow A among Fig. 6 D 2.

In a modification (not shown) of the foregoing description, protrusion tab 32A can omit and local fusing district 32B is arranged on paillon foil near tearing on the part that starts structure 32D.Certainly, start the outside that structure 32D should just be arranged on this weld junction although tear, fusion area 32B can follow weld junction 32E unanimity.

Fig. 7 shows an embodiment, although implement in a different manner, by operate similar to the above embodiments.

This embodiment comprises container body 41, the paillon foil 42 on hard relatively substrate 42A, lid 43 and collar 44.

Paillon foil 42 is arranged on the hard relatively sheet 42A that substrate for example made by cardboard or plastic material, and joins container lip 41A to along weld junction 42B.The antelabium 41A of sheet 42A propelling container 41 is outer and place and cover on 43 the 43A of inner projection portion.

In this example, when lid 43 along opening that direction (arrow A 1) is rotated and therefore relative container body 41 upwards (arrow A 2) when moving, paillon foil 42 is by the jut 43A joint of the part of the propelling container antelabium 41A that mentions sheet 42A and upwards mention.Therefore paillon foil 42 is subjected to peeling force, shown in Fig. 7 B.

Be to be understood that this similar and the foregoing description.Except the top that replaces paillon foil is engaged to lid it can be moved up and being raised with lid, paillon foil is raised to weld junction 42A by transmitting this power that makes progress by means of the mechanical engagement of the substrate of substantially rigid and lid.

Fig. 8 A to Fig. 8 F shows the 6th embodiment, and it is the further improvement of the embodiment shown in top Fig. 3.

In this embodiment, preform paillon foil 52 so is mechanically fixed to covers 53 downside, promptly go up and subsequently adapter plate 55 is pressed onto jut 53A and go up, so the core of paillon foil is clipped to and covered 53 downside by the hole 52A in the paillon foil being joined to the jut 53A that covers on 53 downsides.Also can use the mechanical engagement of other form.In case paillon foil 52 is in place, these juts 53A can carry out for example forge hot, thereby enlarges their head, makes paillon foil not remove from it.Also can use adhesive bond or welding (as in the embodiment described above).

Also be provided with annular projection 53B at lid 53 downside, thereby form the hole sealing against the inside of container body ordinatedly.

Paillon foil 52 preferred so preforms make its outer most surrounding hole sealing (jut) 53B assemble and abut against (shown in Fig. 8 B) on the outside face.Therefore, when lid 53 is assembled on the container body 51 (shown in Fig. 8 B), the outside limits of paillon foil 52 is between the inside face 51B of hole sealing 53B and container body.

The antelabium of container body 51 provides the plastic material of big block in the back of surperficial 51B.When joining paillon foil 52 to, this is important as the part on the surface that is easy to fusion.Shown in Fig. 8 A, before engaging, surperficial 51B is convex form, yet behind joint its flat substantially (shown in Fig. 8 B).

Hole sealing 53B applies pressure to paillon foil 52, is resisted against on the surperficial 51B to keep it.Therefore this strengthened the joint between paillon foil 52 and the container body 51.In the make position shown in Fig. 8 B, owing to being added in power on the paillon foil 52, elevated pressure in the container only can be applied to composition plane between paillon foil 52 and the surperficial 51B abreast, promptly as shearing force (rather than as peeling force) to joint.

In assembling process, above-mentioned configuration also is favourable, because hole sealing 53B keeps paillon foil 52 abuts on surface 51B, therefore helps forming joint by induction soldering between them.

Above-mentioned being configured between paillon foil 52 and the container body adopted welding, and with paillon foil 52 weldings, mechanical engagement or bond to and cover 53.If paillon foil is fused to container body and lid simultaneously, the upper surface that the lower surface of paillon foil 52 need join the surperficial 51B of container and paillon foil 52 to is engaged to and covers 53 downside.Yet, should avoid sealing formation joint between the 53B in the upper surface and the hole of paillon foil 52.A kind of mode that addresses this problem be will have a different melting points different materials for example two kinds of different polyethylene layers be pressed onto the two sides of paillon foil 52.Therefore, upper surface can be designed to spend weldings in lower temperature such as 190 such as 210 degree weldings and lower surface in given temperature.Therefore fusion temp between these two temperature values can be used to the lower surface of paillon foil is fused to surperficial 51B, and the upper surface of paillon foil can be fused to hole sealing 53.So higher fusion temp can be used in the downside that the upper surface of paillon foil is fused to lid at regional area (away from hole sealing 53B).

If the paillon foil that uses has plastic coat in its both sides, then above-mentioned feature can be used for avoiding the upper surface of paillon foil to be welded to the hole sealing, and certainly, this paillon foil is attached to and covers.Perhaps, near the sealing of hole, the plastic coat of the upside of paillon foil can omit or remove.

When container will be opened, lid 53 relatively rotating of collar 54 made the relative container body 51 of lid begin to rise, thereby the hole seals 53B and moves up and unclamp the exterior pressure that is applied to paillon foil.Therefore the rotation that is attached to paillon foil 52 cores that cover 53 downsides is applied to the joint between paillon foil and the container body with peeling force (in the mode of describing among the embodiment above-mentioned), shown in Fig. 8 C.

Cover 53 downside although paillon foil 52 remains fixed to, it can not interfered and covers 53 and ressemble container body 51 (in case for example the sealing between paillon foil 52 and the container body 51 destroys, covering the danger that content and/or reduction are overflowed) temporarily.Fig. 8 D shows and covers 53 and ressemble container body 51 by this way.

Fig. 8 E is the enlarged view of Fig. 8 B.Another advantage of shown configuration is that hole hermetically-sealed construction 53B can make by injection moulding, and need not in mould to use the side form core, can be by being arranged on the perforate 53C formation of cover 53 top because cover the recessed feature of the side in 53 skirt sections.The close hole that also shows paillon foil 52 seals the downside of the edge no show lid of 53B.This is important to the edge joint of being avoided paillon foil 52 to lid.

Fig. 8 F shows the view that lid is seen from downside, shows the jut 53A and the annular opening sealing 53B that are used to admit clamping plate 55.

The foregoing description shows such container, and wherein closing means comprises the lid that is enclosed within on the collar, is fixed to container body by the collar lid.Yet, also can use the enclosed construction of other form that does not adopt this collar.Lid for example can be directly mounted to container body and be fixed to container body by exterior band or collar around lid, and for example WO2006/003453 describes.Can use other fastening device to help lid is fixed to container body.Usually, for customer's large container of beverage therefrom, preferably avoid on container body, being provided with screw thread.Yet for example bottleneck is provided with helicitic texture and allows on having than the container body of narrow opening.

Fig. 9 A to Fig. 9 D shows another embodiment, wherein is similar to the sealing relevant with Fig. 8 above-mentioned, adopts single-piece closing means 63 to be applied on the narrow neck opening of container body 61.Closing means 63 is designed to shift onto on the container body 61 vertically, make structure 61C snap fit on the neck of a part and container body 61 of skirt section 63C of lid, but can by cover 63 and container body 61 between the engaging of rotation releasing and these structures.This closing means (not having the paper tinsel sealing) is also described in WO2007/057659 to some extent.

In this embodiment, preform paillon foil 62 is adhesively secured to and covers 63 downside, shown in Fig. 9 B (although also can use the joint of other form).

Annular projection 63B is arranged on and covers 63 downside, to form the hole sealing near the mounted inside of container body 61.

As fwd embodiment, paillon foil 62 is made the outside of paillon foil assemble and lean on (shown in Fig. 9 B) on its outer surface around wound hole sealing 63B by preform like this, and the outside limits of paillon foil 62 is between the inside face 61B of hole sealing 63B and container body.

Paillon foil preferably has plastic coat at its downside and is used to join to surperficial 61B, but side does not have coating thereon, so the metal level of paillon foil can directly be bonded to and covers 63 downside.

Hole sealing 63B applies pressure to paillon foil 62 to keep its abuts on surface 61B.Therefore this strengthened the joint between paillon foil 62 and the container body 61.In the make position shown in Fig. 9 B, owing to being added in power on the paillon foil 62, elevated pressure in the container only can be applied to composition plane between paillon foil 62 and the surperficial 61B abreast, promptly as shearing force (rather than as peeling force) to joint.

When container will be opened, lid 63 relatively rotating of container body 61 made and cover relative container body 61 risings of 63 beginnings, thereby the hole seals 63B and moves up and discharge the exterior pressure that is applied to paillon foil 62.Therefore the rotation that is attached to paillon foil 62 cores that cover 63 downsides is applied to peeling force (in the mode of describing among the embodiment above-mentioned) joint between paillon foil 62 and the container body 61, shown in Fig. 9 C.

Cover 63 downside although paillon foil 62 remains fixed to, it can not interfered and covers 63 and ressemble container body 61 (in case for example the sealing between paillon foil 62 and the container body 61 destroys, being used to cover the danger that content and/or reduction are overflowed) temporarily.Fig. 9 D shows and covers 63 and ressemble container body 61 by this way.

Though will be fixed at closing means under a lot of situations of container body, and need closing means to rotate from container body and remove closing means relative to container body this.In some cases, may need for example lifter motion of motion, curvilinear movement or the lever motion of other form to replace rotating.Such example is also described in WO2006/003453 to some extent.In these cases, closing means still is rotated certain angle, also therefore begins to apply peeling force on paillon foil before closing means is removed by lifter motion, curvilinear movement or lever motion with the distortion paillon foil.In other cases, the effect of peeling off can cause by lifter motion, curvilinear movement or lever motion, and need not any rotation of closing means.Can for example be modified as a plurality of embodiment that illustrate in the drawings, make the effect of peeling off cause by a part that promotes closing means.

Be to be understood that, more than all embodiment paillon foil is separated with engaging of lid with the junction and the paillon foil of container, therefore allow to cover and before the shearing strength value resistance that runs into paillon foil and container joint, begin to rotate and promote, and geometry so disposes, power on the feasible joint that is applied to subsequently between paillon foil and the container is peeling force, therefore paillon foil can be peeled off from container.

Described embodiment makes can use paillon foil, thereby than traditional container cover be sealed into container better sealing is provided, make paillon foil can hold back a large amount of pressure (because of the performance requriements that reduces lid and so cost-cutting) and also provide convenience and opening operation intuitively, thereby remove lid and paillon foil with simple action for the customer.
