Fig. 4 provides second embodiment 2000 of container airtight 20.

In Fig. 4, parts 30 are illustrated as basic plane but cover attachments 34 be roll and connect securely or be positioned in the recess 120 of the sleeve 110 that enters lining 100.The cover attachments of rolling 34 forms coiling disc spring (wound coil) union end 306 of parts 30, and it is constructed substantially into coiling disc spring formula laminated spring.The cover attachments of rolling 34 can be reeled or coiling with cw or conter clockwise as required.

It is one that coiling disc spring union end 306 collection is fixed on both functions of cover attachments 34 in the recess 120 and force-applying piece 36, and wherein power is provided by the coiling disc spring.

In addition, coiling disc spring union end 306 also is configured to the lid guide 38 of function unit 30 directions, as hereinafter being described in more detail.

Fig. 5 is the part backplan of the sleeve 110 of lining 100, and it illustrates exemplary parallelepiped recess 120.The parallelepiped shape of recess 120 is configured to coiling disc spring union end 306 (or abbreviating coiling disc spring 306 as) snugly admitted and is positioned wherein and is used for controlling the direction of coiling disc spring union end 306, and the direction of taking this parts 30 also is controlled.

Fig. 5 a is the figure of embodiment 2000 of obturator 20 that the lid 32 of unlatching is shown.In this example, lid 32 is connected in parts 30, even cover 32 integral parts that preferably are embodied as parts.Disc spring 306 of coiling shown in the figure and slit 124 and magnet 80, they have improved 32 the airtight power on opening 12 of covering.

Fig. 6 and Fig. 7 illustrate the exemplary embodiment 3000 that is intended to improve the lid guide function that covers guide 38.With reference to one group of right-handed Cartesian coordinate system, wherein the x axle is drawn along the length of parts 30.The inclination of parts 30, deflection or canting are respectively with respect to the pivot around y axle, z axle and x axle.

The cover attachments 34 that Fig. 6 is illustrated in attached end 302 places of parts 30 ends can be constructed with along two projections 308 that extend laterally coiling disc spring 306.These two projections 308 are configured to parts 30 are connected in supporting member 40, and are used for lid 32 is guided and be directed to opening 12.Not shown supporting member 40 of Fig. 6 and opening 12.

In Fig. 7,, the length of the parallelepiped recess 120 of Fig. 5 extends to form projection recess 122, in order to admit coiling disc spring 306 and two projections 308 therein at two opposition sides thereby here being expressed as by slit 124.Projection recess 122 is the way of realization of supporting member annex 42 thus.Slit 124 is used for holding therein each or a plurality of projection 308 in two projections 308.Projection recess 122 is configured to admit therein and the disc spring 306 and be used for function unit 30 and will cover 32 motion and the directions that are applied on the opening 12 of keeping reeling.Lateral protrusion 308 is improved control to the deflection of parts 30 and tilted orientation to guarantee to cover airtight being engaged on the opening 12 of 32 sealings.

Referring to Fig. 6 and Fig. 7.When lateral protrusion 308 connects (for example passing through flush fit) in slit 124 time regularly, the limit movement of parts 30 and lid 32 is on one degree of freedom only, and this is the displacement on the degree of dip.Flush fit is also referred to as force fit or powerful the cooperation remains on projection 308 in the slit 124 with the plastic deformation by slit, or keeps by other means known in this area.If necessary, coiling disc spring 306 also can remain on the parallelepiped part 120 of projection recess 122 regularly only to allow the displacement of parts 30 degree of dip.Thus, the displacement of parts 30 is confined to only one degree of freedom, i.e. degree of dip, and this is the displacement around the y axle.

Comparatively speaking, when slit 124 was configured to bearing fit or slip hold mode admittance lateral protrusion 308, lateral protrusion 308 can be along slit 124 translation glidings in slit 124.Bearing fit refer to only allow sliding translation but in fact projection 308 without any the motion narrow gap.Thus, parts 30 are not that cantilevered construction is pivoting around single position regularly, but lateral protrusion 308 can " be floated " along the height or the degree of depth of slit 124.This mobile or translation or " floating " along projection recess 122 height allows the displacement of parts 30 along two degree of freedom, promptly tilts and translation in height.Therefore highly here, the translational displacement that refers to lateral protrusion 308, and also be that parts 30 and lid 32 are along slit 124 height of projection recess 122 or the displacement of the degree of depth, therefore along the z axle.

Yet by the slit 124 of appropriate size, the slip of lateral protrusion 308 keeps also allowing its translation and need not to make projection to remain on sustained height or level, also makes two lateral protrusion 308 be positioned at different height or is oblique with respect to sleeve 110 for example.Therefore, elongated member 30 can be around its vertical x axle canting.Parts 30 and then cover 32 slip maintenance or the translation displacement of " floating " allows the displacement of three degree of freedom at this moment, i.e. inclination, canting and along the translation of height.

In addition, when slit 124 is configured to easy fit---having thus than the bigger gap of bearing fit---when admitting lateral protrusion 308, form additional degrees of freedom, this allows parts 30 and then covers 32 along four degree of freedom displacements, i.e. inclination, canting, deflection and edge height translation.Deflection is the pivot around the z axle.

Parts 30 allow to cover 32 and are self-aligned to opening 12 and improve that it is airtight with " floating " with a plurality of degree of freedom attached supporting member 40 of remaining in.Therefore when producing,, do not need very accurately to make parts 30 to guarantee correctly to close opening 12 by lid 32 in alignment with projection recess 122 in the 20 assembling stages of obturator.

The opening that can stop slit by assigning to narrower part prevents that lateral protrusion 308 from deviating from from slit 124.For example, plastic deformation can inserted lateral protrusion 308 the wherein width of back restriction slit 124 on sleeve 110.

Coiling disc spring 306 can be exerted pressure before two projections 308 are fit into projection recess 122 in advance, with to parts 30 and then cover the 32 airtight power of prestrain that are provided on the opening 12.

The parts 30 of embodiment 3000 have still made up lid 32, cover attachments 34, force-applying piece 36 and lid guide 38, but be now coiling disc spring 306 integrated whole three kinds of functions of cover attachments 34, force-applying piece 36 and lid guide 38.Preferably reserve very short in addition the practice in non-existent interlude 301 be connected in cover 32 and cover attachments 34 between section.

Fig. 4 and Fig. 8 provide the example of embodiment 300, and it illustrates how to improve the tight seal that covers 32 pairs of openings 12.

The sealing member 70 that will cover shown in Figure 4 adds to opening 12 sleeve 110 on every side.Lid sealing member 70 may be configured to be placed in the O shape ring (O-Ring, it is a trade mark) in the lid seal channel 126 of coupling.Also can be same purpose and select other sealing member known in the art.Perhaps, the lid sealing member can be connected in and cover 32 sealing up sleeve 110, but lid preferably maintenance is in light weight as far as possible.

Fig. 8 illustrates substituting autoregistration sealing improvement method, and its middle cover 32 has and is configured to mate and the local depression 322 that stretches into opening 12.Depression 322 is strengthened and increases covering 32 rigidity, therefore forms the bending of periphery plate-like, for example the lid limit lip of the forging bending shown in Figure 10 c.

Fig. 8 .1 illustrates another embodiment, and wherein force-applying piece 36 has along the coiling disc spring union end of coiling with Fig. 8 opposite sense 306.

Refer again to Fig. 4, how to improve the example of lining 100 shown in Fig. 4 with respect to the tight seal of container 10.

Fig. 4 illustrates and supporting member sealing member 72 or gasket seal 72 can be added into liner head 128.Gasket seal 72 can be configured to be placed in the O shapes rings (being trade mark) that are arranged in liner head 128 adjacent coupling gasket seal grooves 130 on the liner head surface 132 of container 10.Also can be same purpose and select other known in the industry sealing member.

Even force-applying piece 36 provides the lid Final 32 is tried hard to recommend the sufficient airtight power that is pressed on the opening 12, but also using magnetic force further strengthens airtight power.

In Fig. 4, magnet 80 can be embedded with the coupling magnet receptacle 134 that is held in place regularly on liner head surface 132 in and relative with lid 32, preferably relative with lid free terminal 324.For enhancing power, more magnets 80 can be embedded in liner head surface 132 if want.Be preferably disposed on supporting member 40 or be arranged on one or more magnets 80 on the liner head surface 132 among Fig. 4 and when making, positive attractive force can be applied to and cover on 32, and strengthen covering airtight on opening 12 by ferromagnetic material.

Can't help ferromagnetic material as operculum 32 and make, this material can be attached to lid so.Instead, one or more magnets can be fixed in and cover 32.Equally, if lining 100 can't help ferromagnetic material and make, then can with magnet 80 or even the same way as of one or more magnets this material is attached to liner head surface 132.

---weight that does not therefore have cover attachments 34, force-applying piece 36 and lid guide 38---preferably keeps in light weight as much as possible to note the lid 32 and the non-attachment portion of parts 30.This makes when container 10 and for example drops or the acceleration force that is formed on parts 30 because of during transportation shock and vibration reduces to minimum.The airtight power that is applied by force-applying piece 36 is big as much as possible with respect to the weight of parts 30 non-retaining parts.

For example for the obturator 20 that is configured to normally closed oil drum, the weight of arm 30 can reach about 15 grams and force-applying piece 36 can be on opening 12 application of force, this power is measured as about 450 grams in the central authorities of lid 32.When strengthening by magnet 80, crack force generally reaches about 2 kilograms.It is controlled opening obturator 20 required crack forces, and selects predetermined crack force at the place occasion as required.Therefore lid 32 is normally closed, but when applying predetermined force that priori value selects and push with displacement, lid 32 can be opened.Crack force in this example points to inner IN from the outside EX of container 10, but opposite sense also is fine.

Confirm the seal ability of this device 20 from 3 meters tests that highly repeat to drop into concrete floor.

Embodiment 2000 can jointly work with the fluid-flow control apparatus of for example cock 60 and have cover 50 with 1000 same way as of describing hereinbefore in conjunction with the embodiments.

Fig. 9 illustrates has the 4th embodiment 4000 that cooperates to live the flip-over type lining 101 in aperture 102 from container 10 inner IN.

In Fig. 9, flip-over type lining 101 is illustrated as to be introduced aperture 102 and therefrom protrudes outwards to outside EX, thereby remains on container top 14 by flange 90.Flip-over type lining 101 has the coupling external screw thread 104 of the negative thread 92 that is configured on the mating flanges 90, and the inner passage 106 that externally provides fluid to be communicated with between the EX and inner IN also is provided.If necessary, lining 101 can be fixed in container top 14 and not need flange 90 by those skilled in that art's known devices.
