Description
Invention field
The present invention relates to roll-on applicator.Roll-on applicator of the present invention makes can ventilate between described applicator inside and outside.
Background of invention
Roll-on applicator in the known this technology.Above-mentioned these applicators are container normally, and this container comprises the fixed support of hollow body, ball and the fixing above-mentioned ball of holding liquid.These roll-on applicators generally can spread upon the liquid film in the hollow body on the selected surface.The common problem of these applicators is to prevent that above-mentioned roll-on applicator is in the seepage of the liquid of adorning or overflow between the operating period not.Prior art solves this problem by being used a lid.In fact, as disclosed in U.S. Patent No. 3 036 328,4 221 494,4 221 495,4 475 837 and 5 051 017, when container during by cover closing, ball is stressed and cooperate with the sealing surfaces of said fixing supporting member and be pressed against on this surface.If but the said fixing supporting member that has ball is positioned at the liquid level below of the liquid of adorning, then this solution seepage or the method for overflowing are inconvenient.In fact, seepage or overflow and to occur in the operating period of backing out lid.For this reason, the applicator of prior art often makes the fixed support of ball only be contained in the top of corresponding container, when said vesse is in stand up position and stores, be positioned at inclusion above.
Another shortcoming of prior art roll-on applicator is the dispersion volume that can not increase liquid.On the contrary, prior art can only reduce above-mentioned dispersion volume.In fact, the rolling application device described in the prior art above-mentioned can force the sealing surfaces of ball engagement said fixing supporting member and be pressed against on this surface, thereby reduces or termination inclusion flowing on ball.Opposite process is till the ass ascends the ladder.On the contrary, particularly increasing dispersion volume during the stain on pretreating fabrics is of great use.In fact, in order more effectively to carry out preliminary treatment, various stains may need more cleaning solution.For example, the stain that is formed by some component may need more washing agent to obtain more effectively preliminary treatment.The cleaning solution that also needs more amount for the scope that covers stain itself simply.
The problems referred to above are resolved by the roll-on applicator described in the common unsettled european patent application No.94870179.2.Above-mentioned roll-on applicator comprises and is suitable for packing into and the container of a kind of goods of providing and delivering.Said vesse comprises the flexible resilient supporting member of hollow body, dispensing mouth, ball and above-mentioned ball.Above-mentioned flexible resilient supporting member presses against above-mentioned ball on the above-mentioned dispensing mouth, thereby forms non-leakage joint between above-mentioned ball and above-mentioned dispensing mouth.Elastic deformation can take place when masterpiece is used on the above-mentioned ball outside in above-mentioned flexible resilient supporting member, and throw off the above-mentioned non-leakage bonding part that forms between above-mentioned ball and above-mentioned dispensing mouth thus, make the goods of adorning can spread out by above-mentioned ball.In fact, above-mentioned flexibility and elastic supporting piece and above-mentioned ball play the effect of a valve jointly, and this valve is opened when depressing above-mentioned ball.
We find, utilize above-mentioned flexibility and elastic supporting piece that above-mentioned ball is pressed against on the above-mentioned dispensing mouth and also can reach airtight joint.Below " airtight joint " speech be meant do not have gas can pass bonding part between the inside and outside portion of container fully.Perhaps " airtight joint " speech also refers to be discharged into the speed (hereinafter being called " rate of pressure release ") of container outside less than the speed that produces pressure in said vesse by this bonding part.Therefore in said vesse, form pressure, because the gas flow that can escape into the said vesse outside is with respect to the pressure that forms and Yan Taixiao in said vesse.
There are many possible factors to cause and produce pressure in the said vesse, for example Feng Zhuan inclusion may be chemically unstable, gas perhaps easy and that this packaging part head space partly exists reacts, and perhaps may react with packaging material itself under some particular case.Any chemical reaction that relates to fluid contents generally can produce gas, thereby causes the excess pressure in the packaging part.During external temperature when the temperature of topping up and airtight container significantly is different from loading, transportation and stores, the pressure in the said vesse also can increase.Even when the atmospheric pressure of container topping up is different from another atmospheric pressure at diverse geographic location, also can the build-up of pressure difference.
We find, when the pressure in said vesse increases, can further increase the air-tightness between above-mentioned ball and the above-mentioned opening or further reduce rate of pressure release.In fact, internal pressure will make above-mentioned ball further be pressed against on the above-mentioned dispensing mouth, thereby further reduce rate of pressure release.Rate of pressure release can drop to and almost completely not discharge any pressure.
We find that also in common unsettled european patent application No.94870179.2, goods may overflow outward when the pressure in the described roll-on applicator has raise.For the goods that comprise are coated on the ball, must be inverted said vesse, so that said products is sent on the above-mentioned ball.If above-mentioned ball and above-mentioned flexible resilient supporting member always are positioned under the injection liquid level of said products together, then do not need to reverse container.Yet in both cases, when depressing above-mentioned ball, just between above-mentioned ball and above-mentioned dispensing mouth, form a clear passage.Therefore the gas that accumulates in the said vesse tends to promptly overflow by above-mentioned passage as having the hiccups.Thereby the goods between above-mentioned trapped gas and above-mentioned clear passage also eject in the uncontrollable mode that is exceedingly fast.The goods of this quick discharge cause dirty and messy and waste.In fact, the goods of discharge can also be coated on other zone that the user do not wish to cover.In addition, the product amount of discharge possibly can't control greater than requirement.
Therefore the purpose of this invention is to provide a kind of non-leakage container, this container comprises roll-on applicator, but this applicator can be ventilated, thereby can prevent goods to discharge in said vesse because of the driving that is subjected to the pressure that forms in the container, avoids the pollution and the waste of the goods of adorning thus.
Summary of the invention

Detailed Description Of The Invention
Fig. 1 a and 1b illustrate the cross-sectional view of the embodiment of container of the present invention (10).The invention provides a kind of container (10) (Fig. 1 a only part illustrates) that is suitable for splendid attire and dispensing goods." container " speech comprises the container of any form and/or kind, and this container comprises hollow body (1) and dispensing mouthful (2).For example bottle, pipe, metering device and/or dispenser all are containers that the present invention defines.The hollow body 1 of container can be made of hard, soft or flexible material.The most handy soft or flexible material, so that hollow body itself can be pushed, thereby further control is by the dispenser of opening, specifically for metering and/or dispenser, the material of the most handy water-fast temperature to 95 of above-mentioned hollow body ℃ is made.Above-mentioned dispensing mouth is positioned at the top of said vesse.Hereinafter, " top of said vesse " is meant when container is positioned at stand up position, from the part of above-mentioned dispensing mouth down to the said vesse of the high liquid level (HLL) of dress goods, perhaps when said vesse for example is bottle, is meant its neck.In addition, " axis of container " is meant the direction perpendicular to base, and said vesse is positioned at its erectility on this base.
Particularly, above-mentioned metering and/or dispenser are suitable for pretreating fabrics, for example resemble described in WO92/09 736 and/or the WO92/09736 and install.Be suitable for carrying out pretreated above-mentioned metering and/or dispenser and generally include another opening, this opening is used to make liquid to inject this device.When this device was in fabric is placed on washing machine, above-mentioned inlet also allowed inclusion is dispensed in the wash liquid of washing machine during washing operation.When above-mentioned metering and/or dispenser were positioned at stand up position, inlet was usually located at the top of this device.
Preferably select partially or completely transparent hollow body (1),, and be convenient to measure and measure with metering and/or dispenser so that the user can see the amount of the goods of adorning.As another preferred scheme, said vesse has the top of the other parts inclination of above-mentioned relatively hollow body, and promptly above-mentioned dispensing mouth is not on the axle of said vesse.Can reduce like this by the dispensing of above-mentioned dispensing mouth the needed inclination angle of the goods of adorning.As another preferred scheme, above-mentioned hollow body also comprises at least one metering line (Fig. 4 11) on its outer surface and/or inner surface.The most handy plastics of said vesse for example polypropylene, polyethylene, polyurethane or polyvinyl chloride are made.
Container (10) is suitable for the carrying liquid material.Said products preferably liquid washing agent.According to the present invention, liquid detergent can comprise any composition known in this technology.These compositions comprise surfactant, foam inhibitor, bleaching agent, chelating agent, builder, enzyme, filler and perfume.
Essential feature of the present invention is ball (3).Above-mentioned ball locates to be positioned at partly above-mentioned hollow body (1) at above-mentioned dispensing mouth (2), and promptly above-mentioned ball to small part protrudes from above-mentioned dispensing mouth, and promptly above-mentioned ball is arranged in the top of said vesse.The size of above-mentioned ball and above-mentioned dispensing mouth is fitted to each other, and makes ball can not deviate from the outside to above-mentioned hollow body usually from above-mentioned dispensing mouth.During use by the inclusion in the above-mentioned ball dispensing said vesse, because above-mentioned ball always contacts with goods in the said vesse (10).In use, a part of above-mentioned inclusion contacts with above-mentioned ball, and the rotation by ball just is applied to these goods on the surface of said vesse outside then.
Above-mentioned ball (3) can be hollow or solid, and has general smooth outer surface or have the outer surface of certain roughness.Above-mentioned ball can be made of perforate or hole-closing structure.Above-mentioned ball is rigidity preferably.Use spherical ball to allow unoriented diffusion, if can not rotate equivalently in any direction because spherical ball is not fixed on the axle.Can utilize the ball of other shape, for example cylindrical or elliposoidal.But its effect of this ball is restricted, because the ball of this shape can only rotate around an axis substantially.The present invention preferably adopts the spheroidal ball so that carry out omnidirectional diffusion.We find, for during pre-processing no matter the shape of stain how and can be accurately and dispensing liquid washing agent easily, this feature is of great use.On the contrary, rotate if ball is only limited to along axis, then user's hand must carry out for example wristlock etc. of complicated motion.The ball that adopts omnirange to rotate can be better controlled when spreading.Thereby can avoid the waste of washing agent, only on limited stain zone, spread because be easy to.
Specifically for metering and/or dispenser, the material of the most handy water-fast temperature to 95 of above-mentioned ball ℃ is made, and for example can use plastics, as polyethylene, polypropylene, polyurethane or polyvinyl chloride making.
Ball (3) separates manufacturing with hollow body (1).Then ball was pushed away simply the antelabium (9) of above-mentioned dispensing mouth and be inserted in the above-mentioned flexible resilient supporting member through above-mentioned dispensing mouth.This is possible, because the above-mentioned antelabium (9) of above-mentioned dispensing mouth is soft to the elastic deformation that is enough to produce slightly, because above-mentioned antelabium preferably adopts plastic production as the part of hollow body or flexible resilient supporting member.Container (10) also can comprise more than one ball (3), they separately be fixed in the different dispensing mouths (2) or common dispensing mouth in.
The flexible resilient supporting member (4) that is used to support above-mentioned ball is another essential feature of the present invention, and above-mentioned flexible resilient supporting member is pushed against ball (3) on the above-mentioned dispensing mouth (2), thereby forms non-leakage sealed engagement between above-mentioned ball and above-mentioned dispensing mouth.Therefore above-mentioned flexible resilient supporting member cooperates with above-mentioned ball and closes above-mentioned dispensing mouth.This supporting member is positioned at the top of container.In a preferred embodiment, above-mentioned flexible resilient supporting member is pressed against on the outer most edge or antelabium (9) of above-mentioned dispensing mouth above-mentioned ball.We find, the non-leakage basically liquid of joint that forms between above-mentioned opening (2) and the above-mentioned ball by above-mentioned flexible resilient supporting member pushing.Hereinafter, " non-leakage basically liquid " means when unique power of destroying sealed engagement between above-mentioned ball and the above-mentioned opening on acting on said products only is made of hydrostatic pressure, and above-mentioned sealed engagement can stop goods to flow.Therefore in the time spent of doing that does not add upper cover, can avoid do not use said vesse (10) during big seepage takes place or overflow.
As preferred version, the above-mentioned antelabium (9) of above-mentioned flexible resilient supporting member is flexibility or deformable.Therefore flexible or deformable antelabium can mate and/or compensate any defective of above-mentioned ball shape, for example when ball has unfavorable ball shape.For reaching this point, antelabium above-mentioned flexibility or deformable can be made of independent material, and this material can be fixed on the outer peripheral edges of dispensing mouth.The above-mentioned flexibility of above-mentioned flexible resilient supporting member or deformable antelabium also can be made by common injection moulding, be about to form the flexibility of above-mentioned antelabium or deformable material for example rubber carry out the while injection moulding with the more hard material that forms above-mentioned flexible resilient supporting member remainder.Flexible or deformable antelabium does not influence the intensity and/or the structure of above-mentioned flexible resilient supporting member.
The external force that acts on the above-mentioned ball (3) can make above-mentioned flexible resilient supporting member (4) produce strain.When therefore above-mentioned ball being pushed away in above-mentioned container, the non-leakage basically sealed engagement between above-mentioned ball and dispensing mouthful (2) just can break away from cooperation.Thereby above-mentioned ball can freely rotate and scatter inclusion, and this is because the clear passage between above-mentioned antelabium (9) and the above-mentioned ball makes inclusion be connected with the projection of above-mentioned ball.Clear passage between above-mentioned antelabium (9) and above-mentioned ball is called " goods flow channel " hereinafter.Stop above-mentioned ball is pushed away in above-mentioned container in case work as external force, then non-leakage basically sealed engagement just forms at once automatically.Close the goods flow channel subsequently, cut off goods flowing from said vesse inside.The above-mentioned ball that is pressed against on the above-mentioned dispensing mouth forms sealed engagement, and this sealed engagement makes said vesse that seepage not take place when not using basically.
Flexible resilient supporting member of the present invention (4) is suitable for making said products to flow out from said vesse inside.In fact, user's change acts on the size that the external force on the above-mentioned ball just can be regulated passage between above-mentioned antelabium (9) and the above-mentioned ball (3).Therefore, just can control the product amount that flows out in the said vesse by the size that changes above-mentioned passage.Particularly, further just can obtain bigger goods to the internal tank pressure ball flows.In addition, above-mentioned flexible resilient supporting member combine with flexible container by push above-mentioned ball and the above-mentioned flexible container of extruding can also be directly with dispenser or be injected on the surface.
Fig. 1 a illustrates one embodiment of the present of invention, and above-mentioned flexible resilient supporting member (4) comprises the spring (5) that is positioned at below the above-mentioned ball (3).Above-mentioned spring is pressed against on the above-mentioned dispensing mouth (2) above-mentioned ball (3), thereby reaches above-mentioned non-leakage substantially sealed engagement during not using said vesse.When at the power F that applies on the above-mentioned ball towards said vesse inside, above-mentioned spring generation elastic deformation also forms required goods flow channel, shown in Fig. 1 b.Above-mentioned spring can be fixed on above-mentioned hollow body (1) separately and go up or form its integral part.In addition, above-mentioned spring can be with any possible material for example metal or plastic production, and above-mentioned spring can have any possible shape, for example is disc spring or cylinder spring.
As another preferred embodiment of the present invention, above-mentioned flexible resilient supporting member comprises the arm (6) of at least one elastically deformable in the zone with respect to above-mentioned dispensing mouth, this arm is pressed against on the above-mentioned dispensing mouth (2) above-mentioned ball, thereby forms above-mentioned non-leakage sealed engagement.Above-mentioned arm (6) can bend to angle [alpha] (Fig. 2 a), to obtain above-mentioned elastic deformation performance.Angle [alpha] is preferably between 0～90 ° of angle.Above-mentioned flexible resilient supporting member preferably includes shell (4a), and this shell is contained on the container and forms above-mentioned dispensing mouth on the one end, shown in Fig. 2 b.The assembling of above-mentioned shell and said vesse must be non-leakage, but above-mentioned assembling can be to be screwed on the said vesse or to be buckled on the said vesse by screw thread.Above-mentioned shell and said vesse can easily be re-introduced into goods in the said vesse with the advantage person of being to use who is threaded.Therefore above-mentioned flexible resilient supporting member (4) can be made of shell hard or flexibility, above-mentioned spring of above-mentioned outer casing supporting (5) or above-mentioned flexible arm (6), and this supporting member can be inserted in the above-mentioned dispensing mouth (2).
As the preferred embodiment of the present invention, above-mentioned flexible resilient supporting member (4) comprises more than one above-mentioned elastic deformation arm (6), shown in Fig. 2 b, as the most preferred embodiment of the present invention, all above-mentioned arms link together with described ball at a contact ring or a single contact point (Fig. 2 b, 7).With the contacted unique contact point of above-mentioned ball (7) preferably be positioned on this ball just relative with above-mentioned dispensing mouth (2) a bit.
As another scheme more preferably, above-mentioned flexible resilient supporting member (4) its facing to above-mentioned minute raw edge (2) the zone comprise interrupted edge (among Fig. 3,8), when applying external force, above-mentioned ball (3) is pressed against on this interrupted edge.This means that above-mentioned interrupted edge can prevent that above-mentioned ball further is pulled in the said vesse.But because above-mentioned edge is interrupted, promptly above-mentioned edge has a nonvolatil unlimited inclusion passage at least, so can guarantee the passage of goods circulation.Therefore above-mentioned interrupted edge forms the maximum goods flow channel that is allowed by above-mentioned flexible resilient supporting member.In addition, above-mentioned interrupted edge can be prevented above-mentioned ball further inwardly to be pushed away and damage the danger of the spring of above-mentioned flexible resilient supporting member.
Above-mentioned flexible resilient supporting member (4) can be the integral part or the unitary part of said vesse (10).Above-mentioned flexible resilient supporting member can be made by elastomeric polymers (for example polyurethane rubber, isoprene rubber, butadiene-styrene rubber) such as casting resin (for example polypropylene, polyethylene, polyamide, polyformaldehyde) or thermoplastic elastomer (TPE) or its composition.In addition, can form the flexible resilient supporting member by two stages or multistage injected plastics material, this supporting member has the elastomeric spring that for example has the feature that is rigidly connected.
Above-mentioned lid (20) is another essential feature of the present invention.Fig. 4 a illustrates the above-mentioned lid that is engaged on the said vesse (10).Above-mentioned lid comprises roof (21) and substantially perpendicular to the skirt section (22) of above-mentioned roof.The geared assembly (30) that above-mentioned lid is engaged on the said vesse is a part of above-mentioned skirt section.Said vesse comprises the flexible resilient supporting member (4) shown in above-mentioned Fig. 2 b.But also can use other flexible resilient supporting member (4) among aforesaid for example Fig. 1 a and the 2b.Above-mentioned lid is protected above-mentioned ball, makes it avoid suffering damage when not using.When the above-mentioned lid of engagement fully was in resting position, wherein above-mentioned capping did not all contact this ball facing to the surface (" downside surface " that be called lid later on) of above-mentioned ball in any position.Above-mentioned ball is still up pushed away by the pressure that forms at internal tank, runs into and is pressed at last on the downside surface of above-mentioned lid up to above-mentioned ball.Therefore above-mentioned lid helps to prevent that the pressure that forms from releasing said vesse with ball in said vesse.According to the present invention, when only throwing off when the engagement of above-mentioned lid and this container or with this container, above-mentioned lid just is pressed on the above-mentioned ball, makes and forms clear passage (shown in Fig. 1 b) between above-mentioned ball and the above-mentioned dispensing mouth.Above-mentioned lid engagement or throw off is meant that above-mentioned lid is towards above-mentioned resting position or leave this position motion.
As mentioned above, clear passage just appears when above-mentioned lid is pressed on the above-mentioned ball.This clear passage just appears when above-mentioned lid engagement or disengagement said vesse.This means that carrying out this kind operating period, said vesse is in its stand up position, and head space partly is arranged in the top of said vesse, on said vesse is adorned the goods liquid level." head space part " is the gas volume that fills between the antelabium (9) of the high liquid level (HLL) that is positioned at said products that remains in behind the material in the container and above-mentioned dispensing mouth (2).The gas of above-mentioned subsequently head space part is overflowed by above-mentioned clear passage and can not discharged goods.Therefore said vesse be ventilation and can not take place to pollute and waste.
Utilize above-mentioned clear passage to be confined in the quite short time.In fact, this utilization only is confined to that above-mentioned lid (20) is engaged on said vesse (10) and goes up and throw off this container in the needed time.But we find that this section period is enough to be released at least a portion pressure that forms in the said vesse, thereby have reduced the pressure reduction between the inside and outside portion of said vesse significantly.We find further that also the amount of pressure that reduces by this way is enough to avoid being positioned at above-mentioned ball goods on every side and discharges with pressure release in uncontrollable mode.Therefore the pollution and the waste of the goods of discharging have been avoided basically.The overvoltage that exists in said vesse is defined in the pressure reduction between the pressure of said vesse pressure inside and said vesse outside.When above-mentioned lid was engaged on the said vesse or throws off this container and form clear passage, excess pressure just reduced, and reduced approximately 10% at least, more preferably reduced approximately 50% at least, most preferably reduced about 90% at least.Particularly, we find, when about 250 millibars of the pressure that forms in the said vesse, this pressure are dropped to below 50 millibars to avoid providing and delivering significantly defective.When the gas in the said vesse during the dispensing goods was discharged in above-mentioned mode of having the hiccups, the dispensing defective mainly was to pollute and waste.
Fig. 4 a illustrates the above-mentioned lid (20) that is in resting position.No one contacts above-mentioned ball (3) above-mentioned lid.Particularly, gap (24) separate the outer surface of above-mentioned ball and the inner surface of above-mentioned lid (31).Therefore close above-mentioned dispensing mouth with being pressed against above-mentioned ball air hermetic on the above-mentioned dispensing mouth (2).Hereinafter, " airtight " is meant without any gas and can passes junction surface between the inside and outside portion of container.Perhaps by another kind of saying, " airtight " is meant that pressure is discharged into the speed (to call rate of pressure release in the following text) of external container less than the speed that produces pressure in said vesse by this junction surface.Thereby in said vesse, form pressure gradually, because the gas flow that can be discharged into the said vesse outside is with respect to the pressure that forms in said vesse and Yan Taixiao.Fig. 4 b is a zoomed-in view, above-mentioned lid is shown throws off the state in a flash that above-mentioned lid during the said vesse is depressed above-mentioned ball.The same moment of depressing ball also takes place under the reverse situation when being engaged on above-mentioned lid on the said vesse.During taking off lid, just make bigger air-flow by flowing to the container outside through above-mentioned clear passage (23) shown in the arrow like this.
As mentioned above, when above-mentioned lid engagement said vesse (10) or disengagement said vesse, above-mentioned lid (20) is all depressed above-mentioned ball (3).The method that reaches this point is that geared assembly (30) is set between above-mentioned lid and said vesse, and this geared assembly just guides the roof of above-mentioned lid to shift to above-mentioned ball and be pressed on this ball in engagement with when throwing off lid.We think that possible embodiment should have above-mentioned geared assembly, and this device comprises the screw thread (30 among Fig. 4 c) of inclination.Go up the formation screw thread in the skirt section (22) of above-mentioned lid, on the outer surface of above-mentioned hollow body (1), form other screw thread simultaneously in the below of opening (2).We find that the screw thread on above-mentioned hollow body outer surface should be inclined to and make the roof of above-mentioned lid contact with above-mentioned ball, thereby is pressed on the above-mentioned ball.Above-mentioned screw thread can be the part of the outer surface of the part of said vesse outer surface or above-mentioned flexible resilient supporting member (4).
An embodiment is shown in Fig. 4 c.Above-mentioned screw thread comprises two ribs (32,32 '), forms groove (33) in the middle of them.Make the size of above-mentioned groove can hold respective threaded on the above-mentioned lid fully.One end (33a) of above-mentioned groove opens wide, and its opposite end is sealed by wall (34).Above-mentioned wall (34) preferably makes above-mentioned two ribs (32,32 ') fuse.Therefore for making above-mentioned lid engagement said vesse, the screw thread of above-mentioned lid must enter this groove from its openend.When said vesse was in stand up position, the open end of above-mentioned groove (33) was in the low position of this blind end.This means to press downwards and state lid and can enter above-mentioned groove until its screw thread.
As scheme more preferably, the rib (32) of the most close above-mentioned opening (2) on above-mentioned groove (33) also comprises a sloping portion (35).Above-mentioned sloping portion tilts to above-mentioned opening (2), shown in Fig. 4 d.This inclination helps in the above-mentioned groove of being threadedly engaged to of above-mentioned lid (33).In fact, above-mentioned sloping portion (35) guides the screw thread of above-mentioned lid (20) to get back in the above-mentioned groove when closing said vesse again.Be easy to subsequently rotate, make above-mentioned lid (20) not need down to push lid with above-mentioned geared assembly (30) engagement.As another scheme more preferably, the rib (32 ') that leaves above-mentioned opening below above-mentioned groove (33) also comprises second sloping portion (36), and above-mentioned second sloping portion also tilts to above-mentioned opening (2), shown in Fig. 4 d.This second sloping portion (36) is particularly conducive to the screw thread that makes above-mentioned lid and deviates from above-mentioned groove (33).In fact, above-mentioned sloping portion (36) forces above-mentioned lid upwards, thereby helps the above-mentioned lid of lifting when above-mentioned lid is thrown off said vesse.
Hereinafter, plane P (P among Fig. 2 b) is container and tangent plane of peak of above-mentioned ball when being in stand up position.In addition, dt is the above-mentioned screw thread of above-mentioned lid and the distance between the above-mentioned roof on the above-mentioned lower lid surface (31 among Fig. 2 b), and dc is the distance between above-mentioned open end (33a among Fig. 4 c) and above-mentioned plane (P).Therefore above-mentioned roof is pressed on the above-mentioned ball in the time just can guaranteeing that apart from dt screw thread at above-mentioned lid enters the openend of above-mentioned groove during less than dc.Difference Δ=(dc-dt) can be less than or equal to the maximum displacement that above-mentioned ball is produced by above-mentioned flexible resilient supporting member in said vesse.The above-mentioned lid that further turns left then, until the screw thread of above-mentioned lid by above-mentioned wall (34 among Fig. 4 c) bumping post.The above-mentioned cover closing said vesse in this position.When making above-mentioned lid throw off said vesse, above-mentioned lid also is pressed on the above-mentioned ball.In fact the lid that turns right, above-mentioned lid just moves to openend from the blind end of above-mentioned groove, and promptly above-mentioned lid moves down when above-mentioned blind end forwards above-mentioned openend to.Therefore above-mentioned lid is pressed in again on the above-mentioned ball, thereby opens the clear passage between the inside and outside portion of said vesse.
Above-mentioned lid (20) can comprise the feature to child safety, and this is the another kind of method that forms clear passage when making above-mentioned lid engagement or throwing off said vesse.One embodiment is shown in Fig. 6.In this case, must be at first the screw thread (41) of above-mentioned lid be pushed downwards the above-mentioned groove (33) from space 42, thereby make the screw thread (41) of above-mentioned lid can reach openend (33a), make above-mentioned lid break away from engagement with said vesse.Not toward pressing down, then wall 42 can be prevented the further rotation of above-mentioned screw thread (41) if only rotate the screw thread (41) of above-mentioned lid.
Hereinafter, " airtight lid " is meant a kind of lid, and this lid can prevent basically that gas from flowing to the outside of said vesse.If above-mentioned lid (20) is not airtight, for example flow directly to outside atmosphere by threaded portion just then pass the gas of above-mentioned clear passage.Flow to the outside of said vesse for ease of gas, be preferably formed as at least one pore on the above-mentioned lid.Above-mentioned pore is the hole of passing above-mentioned lid thickness.When above-mentioned lid (20) when closing said vesse with air tight manner, situation is just inequality.In this case, must predict the mode that gas may be overflowed through above-mentioned clear passage (23).Preferably, when the above-mentioned joint between above-mentioned ball (3) and the above-mentioned opening (2) can the low speed release pressure, above-mentioned airtight lid was of great use.In fact, we find, the gas by junction surface between above-mentioned ball and the above-mentioned opening also can outwards extrude a certain amount of flowing product of adorning.Thereby above-mentioned airtight lid can avoid polluting waste.
The simplest method is that gas is escaped first in the free volume between above-mentioned lid and the said vesse (A among Fig. 4 b).Subsequently, after throwing off fully, above-mentioned lid just can discharge these gases in this volume (A among Fig. 4 b) fully.When this volume (A among Fig. 4 b) did not provide enough space for the gas that flows out said vesse, this was not a desirable solution.
For example shown in Fig. 5 a and the 5b as the another kind of airtight lid (20 ') of embodiment.Above-mentioned lid (20 ') preferably also comprises sealing ring (25).Above-mentioned sealing ring is a continuous wall, and this wall stretches out and is in substantially parallel relationship to above-mentioned skirt section (22) from the inner surface of above-mentioned roof (21).Above-mentioned sealing ring surrounds the outer surface of the above-mentioned hollow body (1) in the said vesse top fully.Preferably, above-mentioned sealing ring surrounds above-mentioned hollow body and is positioned at outer surface under the antelabium (9).More preferably, above-mentioned sealing ring surrounds above-mentioned shell (4a) and is positioned at outer surface under the above-mentioned antelabium (9).When above-mentioned lid was in above-mentioned resting position, above-mentioned sealing ring formed non-leakage the connection with the outer surface of above-mentioned hollow body.As mentioned above, when above-mentioned lid broke away from cooperation, above-mentioned lid moved downward and is pressed on the above-mentioned ball.Like this, above-mentioned sealing ring just is depressed on the position on the above-mentioned hollow body outer surface, and above-mentioned sealing ring no longer forms airtight joint in this position, and the above-mentioned gas that therefore flows through above-mentioned passage (23) escapes into the outside of said vesse at last.Provide at least one to work as the pore that is positioned at when said vesse is in stand up position below the above-mentioned sealing ring and help this ventilation.
The embodiment that reaches above-mentioned ventilating mechanism is shown in Fig. 5 a.The top of said vesse also comprises at least one groove (27).When above-mentioned lid during with its resting position sealing said vesse, above-mentioned groove is positioned on the outer surface of the sealing ring in above-mentioned lid (20 ') (25) below of above-mentioned hollow body (1).Above-mentioned groove can be whole succeeding vat around above-mentioned hollow body outer surface.It also is feasible forming the more than one groove that is separated from each other along the outer surface of above-mentioned hollow body.The fluted sustained height that preferably is positioned at.Above-mentioned groove can form by the thickness that reduces between the inside and outside surface of above-mentioned hollow body.Perhaps, when when the outside of said vesse is watched, above-mentioned groove can be the recessed sweep of above-mentioned hollow body wall.
Above-mentioned groove (27) makes and leads to the outside of said vesse from the inner escaping gas of said vesse.In fact, when above-mentioned lid (20 ') when said vesse is thrown off, above-mentioned sealing ring is just down pushed this groove to.In case when pressing against on the above-mentioned groove, above-mentioned sealing ring just no longer guarantees to form airtight joint with the top of said vesse, forms the gap of free space between above-mentioned groove and above-mentioned sealing ring that is:.Subsequently, when above-mentioned lid was depressed above-mentioned ball, the gas that passes above-mentioned clear passage (23) just this gap between above-mentioned groove and above-mentioned sealing ring escaped into the outside of said vesse.When making above-mentioned lid be engaged on the said vesse, same process also takes place.
Another may be shown in Fig. 5 b by embodiment the ventilating mechanism identical with mechanism shown in Fig. 5 a.In this case, above-mentioned groove (27) is replaced by at least one protuberance (28), this means, when above-mentioned lid sealed said vesse with its resting position, above-mentioned protuberance (28) was positioned at being in of above-mentioned hollow body (1) and states on the above-mentioned lid (20 ') on the outer surface of sealing ring (25) below.It also is feasible forming more than one protuberance independent of each other along the outer surface of above-mentioned hollow body.All protuberances preferably are positioned on the sustained height.Above-mentioned protuberance does not connect each other, otherwise just can not form any venting channels.Above-mentioned protuberance can form by the thickness that increases between the inside and outside surface of above-mentioned hollow body, and perhaps, when when the outside of said vesse is watched, above-mentioned protuberance can be the convexly curved part of above-mentioned hollow body wall.
As the preceding explanation that above-mentioned groove (27) is done, above-mentioned protuberance (28) can make gas escape into the outside of said vesse from the inside of said vesse.In fact, when above-mentioned lid (20 ') when said vesse is thrown off, above-mentioned sealing ring just is pushed downwards to above-mentioned protuberance.In case when shifting onto on the above-mentioned protuberance, above-mentioned sealing ring just no longer forms airtight joint with the top of said vesse, that is: form the gap of free space between around being right after of above-mentioned sealing ring and above-mentioned protuberance.In fact, above-mentioned sealing ring is raised partly by above-mentioned protuberance at least, shown in Fig. 5 c.When having more than one above-mentioned protuberance, above-mentioned sealing ring is just raised fully, thereby just flows through the above-mentioned separately free space between the protuberance from the internal tank escaping gas.Thereby when above-mentioned ball was depressed by above-mentioned lid, the gas that flows through above-mentioned clear passage (23) the just free space between above-mentioned protuberance and above-mentioned sealing ring escaped into the outside of said vesse.When above-mentioned lid was engaged on the said vesse, same process also took place.
