Description
Technical field
The present invention relates to a kind of self-closing valve that is used to export flowable products.
Background technology
Typical case's application for self-closing valve is a kind of like this container, in described container, and can be by the extrusion container with flowable inclusion output.For this, the so-called squeeze bottle that is used for the body care agent is exactly an example.The internal capacity that the user reduces squeeze bottle just will improve the pressure in squeeze bottle, make contained product (for example liquid soap) to be output via valve.Even if no longer rely on its action of gravity on the output area of valve even work as container, also will stop inclusion under the situation that does not have pressure to raise, undesirably to be discharged owing to the self closing effect of valve by seal bootr sealing and product.
By the known a kind of self-closing valve of DE 102 18 363 A1, be used for dispensing liquid product or pasty product.This valve comprises valve film, this valve film towards the line of production protruding moulding.Valve film constitutes to have to push at edge side seals the retaining ring of shaping.Valve film is reinforced with plate shape parts, is used for the a/s output of product.Plate shape parts keep by spring arm again, make the infrastructure cost of valve be enhanced thus.Another shortcoming of this solution is, has especially hindered compensated with air by plate shape parts, makes container must have very big reset force.
By the known a kind of self-closing device of DE 196 13 130 A1, be used for exporting the liquid fill of compressible container with sealing diaphragm.The sealing diaphragm has and keeps down edge and last closing cap under not operated installing condition, on this closing cap substantially along outbound course recessed extension.In common course of conveying, from the pressure determined reliably and approximately suddenly open in the aperture slots of sealing in the diaphragm.Container resets when course of conveying finishes, and makes the sealing diaphragm return to the initial condition of spill.At this, the breach of aperture slots is towards inside, makes the air resorption.For improving the resorption of air, lead-ingroove between diaphragm and its support portion can sealed.The shortcoming of this solution is, limited leak tightness and big, for the essential low pressure of resorption.For realizing powerful resorption effect, container must be constituted as has corresponding action of the spring.This is that the high material input with container is a condition, and thus, manufacturing cost is soaring.
By the known a kind of self-closing valve of EP 0 388 828 A1 with disc valve diaphragm.This valve film has transport openings placed in the middle, and this transport openings is placed on the supporting disk and sealing thus.This solution does not have the possibility of air resorption.
By the known a kind of self closing closing appliance that is used for container or pipe of DE 43 29 808 C2, in this closing appliance, the outlet opening in closing cap is by the sealing plug closes.When pressure raise, the sealing stopper should make outlet opening be released towards internal motion, and product just can be discharged by outlet opening.Yet the air in the sealed hollow under the sealing stopper is certain to be compressed for this reason, and this is because described air can not appear towards the outside.Therefore for making the sealing stopper discharge outlet opening, need very large pressure, so that this valve almost can not be employed.In addition, this solution does not have the possibility of air resorption, so that this solution after all is only applicable to certain products.
By the known a kind of self-closing valve of DE 195 80 254 B4 with the valve film that arches upward towards inside.This valve film still has transport openings placed in the middle, and this transport openings is placed on the supporting disk and is sealed thus.Valve film keeps towards the top by keeping wheel rim, valve film radially outer in the zone from below be resisted against on the maintenance flange plate.Stopper can be configured on the supporting disk, and this stopper is in detent position is taken in transport openings and realize effective seal.The side direction of valve film can be implemented like this against the zone, that is, under the low pressure situation, valve film is towards internal modification, and thus, the air path that is used for resorption is released.But such distortion is a prerequisite with big low pressure, so that wall of a container must correspondingly impose big reset force.
Summary of the invention
Therefore task of the present invention is, a kind of self-closing valve that is used to export flowable products is provided, and this self-closing valve can be made very simply and at an easy rate, and only needs little low pressure to be used for the air resorption.In addition, the excellent sealing effect of expectation valve is even if so that avoid the leakage of undesirable a spot of flowable products reliably.
Solve this task by self-closing valve according to claims 1.In described self-closing valve, valve film switches to transfer position for output products from detent position.At detent position, the transport openings of valve film is sealed by backstop.At transfer position, transport openings is lifted away from and is released from backstop.The neighboring of valve film constitutes around seamed edge, and this seamed edge seals backstop at transfer position.Between around seamed edge and side direction guide portion, be provided with the gap, by this gap, when the container that loosens by valve closure, can the resorption air.
A special advantage of the present invention is, can obtain version of simplifying very much and the air resorption that obviously improves simultaneously.Valve film can be made by simple synthetic material disc, and the synthetic material disc can be produced with being dirt cheap.The container that has according to valve of the present invention needn't have big reset force.Therefore wall of a container can approach, and makes by using according to valve of the present invention, make economical with materials and cheap container products become possibility.

The specific embodiment
Fig. 1 illustrates the section drawing of self-closing valve 01 according to the present invention at the four-stage when detent position carries out the transition to transfer position.The illustration of Fig. 1 a) is illustrated in the valve 01 of detent position.Transition to transfer position the illustration b of Fig. 1) and c) is shown, and the illustration d of Fig. 1) be illustrated in the valve 01 of transfer position.Usually, for understanding accompanying drawing explanation, valve is designed to be assemblied in (not shown) on the container, for example by being encased in the neck of squeeze bottle.
Valve 01 comprises the valve film 02 of annular, and valve film 02 has the transport openings placed in the middle 03 of annular.The shape of the disk-shaped substantially spring of valve film 02, and also show relative spring performance.The illustration of Fig. 1 a) in, when valve 01 was closed, valve film 02 illustrated a kind of position.At detent position, valve film 02 places on the stop tab 04 with its transport openings 03.Areal of support that constitute thus, circular 06 sealing transport openings 03 on stop tab 04.In addition, the seal lip 07 of valve film 02 places on the stopper 08 of stop tab 04 with having clearance, and this is because stopper 08 protrudes in the transport openings 03.The shell of stopper 08 is in truncated cone shape and the guidance field 09 corresponding to seal lip 07 inside face.Shown in detent position, arch upward in the shape orientation inside of valve film 02, and if take off seal lip 07, then valve film 02 has the shape of truncated cone shape housing.
Valve film 02 elastically deformable wherein produces pretension by truncated cone shape and seal lip 07 extruding, and this pretension is determined degree of deformation.The neighboring of valve film 02 is by constituting around seamed edge 11.(illustration a) is resisted against on the baffle ring 12 at detent position around seamed edge 11.By baffle ring 12 from top hold-off valve diaphragm 02.The sideway movement of valve film 02 limits by side direction guide portion 13.In the embodiment shown, baffle ring 12 and side direction guide portion 13 combine together mutually, make thus simply to create possibility.Baffle ring 12 and side direction guide portion 13 also can be implemented by minute two parts.In the embodiment shown, side direction guide portion 13 and stop tab 04 are divided two parts to implement.Side direction guide portion 13 and stop tab 04 also can combine together mutually.Side direction guide portion 13 is implemented in the embodiment shown ringwise.But also can implement the side direction guide portion like this, i.e. this guide portion pilot valve diaphragm 02 on several points of periphery or sections only.In the embodiment shown, baffle ring 12 has angled section.But baffle ring 12 also may be implemented as perpendicular to side direction guide portion 13.Valve film 02 be resisted against the below of baffle ring 12 around seamed edge 11, make valve film 02 with respect to baffle ring 12 sealings.Can be by the opening in stop tab 04 14 so that in the product of container (not shown) storage inside or air flow to zone below valve film 02 along direction 16.
Valve film 02 preferably have main body identical materials intensity with valve film 02 around seamed edge 11.Be not enhanced around seamed edge 11, and do not have the F-SP that for example passes through the additional seal lip.Valve film 02 around seamed edge 11 simultaneously with acting on the last backstop and the side backstop of valve film 02.Side direction guide portion 13 and valve film 02 around seamed edge 11 between be provided with gap 15.Gap 15 is in the embodiment shown around distribution.If valve film 02 is for example only guided by side direction at some points, then can in other embodiment, dispose the gap in sectional type ground.
Self-closing valve 01 is particularly suitable for so-called squeeze bottle, and in squeeze bottle, flowable product is output by squeeze bottle manually.For this reason, valve 01 is arranged in being used to export of bottle and in the opening that is provided with.To this, the embodiment according to valve of the present invention shown in Figure 1 has circular fixed mount 21 is arranged, and fixed mount 21 can be loaded in the opening of bottle.But also may be implemented as the integrated constituent elements of container according to valve of the present invention.
Illustration b at Fig. 1) shown in when the pressure at internal tank slightly improves the state of valve 01.This appears at implements manual extrusion process and comes product when squeeze bottle is exported.When masterpiece being used on the bottle by periphery by bottle and not wished output products, also can obtain the slight pressure that improves.By the internal pressure of slight raising, power affacts on the valve film 02 along direction 16.Valve film 02 slight deformation thus.Seal lip 07 since the distortion of valve film 02 and with truncated cone shape stopper 08 wedging in guidance field 09, thereby guaranteed positiver sealing between stopper 08 and seal lip 07.By the distortion of valve film 02, the supporting power of the valve film 02 on baffle ring 12 improves simultaneously, and thus, the sealing effectiveness with respect to baffle ring 12 of valve film 02 is enhanced.Therefore, valve 01 according to the present invention has following advantage, and promptly little pressure improves can not cause product output.For example when opening and sealing the squeeze bottle that has seal bootr, squeeze bottle is steadily held.At this, the internal pressure in bottle is improved slightly, yet does not wish that product flows out.In addition, by the initial deformation of valve film, valve film 02 is enhanced with respect to the sealing of stopper 08, and this is because seal lip 07 is squeezed on the stopper 08 strongly.The cross section of valve film 02 is extended extended by the distortion of valve film 02, thus still remain on stopper 08 back seal against.Even diaphragm should be lifted away from from areal of support 06, under the situation that only has little pressure to improve, in the central area of valve film 02, seal and to keep.
The illustration c of Fig. 1) is illustrated in valve 01 when improving internal pressure once more in the container.Valve 01 just switches to transfer position from detent position before this soon.The internal pressure power that improves causes valve film 02 to be out of shape by this way, and promptly truncated cone shape obviously flattens.This especially is condition with as described below, and promptly owing to the internal pressure that improves, power affacts on the valve film below the seal lip 07 02 along direction 17, and described power is obviously raised valve film 02 in this zone.And stopper 08 still is a leak free with respect to seal lip 07.
The illustration d of Fig. 1) illustrates when internal pressure changes to and make valve 01 switch to the valve 01 of transfer position when so big.Except seal lip 07, valve film 02 obtains approximate flat shape.In the embodiment shown, valve film 02 is very flat truncated cone shape, wherein, this truncated cone shape with point on the contrary in the truncated cone shape of detent position.Also can implement valve 01 by this way, promptly have truncated cone shape at transfer position valve film 02, this truncated cone shape is corresponding to the truncated cone shape of opposite detent position, but has obviously little gradient.Therefore, when detent position switched to transfer position, valve film 02 overturn at valve film 02.The structure of valve film 02 causes, and must overcome the power that affacts the maximum on the valve film 02 in this switching process.Not only can be felt and also can be heard in peaked surmounting of power in when upset by the user.This has improved character of operation, has especially improved being equipped with the operation according to the sense of touch of the squeeze bottle of valve of the present invention.In case valve film 02 switches to the truncated cone shape of reversing, even application force diminishes once more, valve film 02 still keeps the truncated cone shape of this reversing.If power drops under definite threshold value, valve film 02 switches the truncated cone shape that turns back to detent position suddenly.Obtain the sealing moment that limits thus, the liquid beam that this sealing moment causes extruding is cut off neatly, thereby has greatly avoided seepage.
At illustration d) shown in transfer position, seal lip 07 is obviously raised with respect to stopper 08, so that form big opening between seal lip 07 and stopper 08.Product is passed in the opening 14 in the stop tab 04 and passes transport openings 03 output.Directional arrow 18 shows the flow direction of product.The diameter of stopper 08 determines the diameter of transport openings 03, and determines the circulation and the velocity of liquid assets of product thus.
In the embodiment shown, the switching from the detent position to the transfer position is carried out suddenly.This result who causes is that in case the overvoltage that brings by extrusion is disengaged, the squeeze bottle with this class valve 01 is just loosened suddenly in this process.In this moment, with the product of output some.Can determine the size of valve 01 and squeeze bottle like this, so that suddenly Shu Chu product quantity meets the typical consumption of product.User's typical consumption of output products intuitively like this.If wish more output, can be after valve 01 switches to transfer position squeeze bottle once more.Be overcome because be used to switch to the power of transfer position, so only need seldom strength just can export the product of greater number.
Fig. 2 is illustrated in the section drawing at the self-closing valve shown in Fig. 1 01 the three phases when detent position carries out the transition to the resorption position.The illustration of Fig. 2 a) is illustrated in the valve 01 of detent position.The illustration b of Fig. 2) transition to the resorption position is shown, and the illustration c of Fig. 2) be illustrated in the valve 01 of resorption position.
After output products finishes, enter at the illustration of Fig. 2 detent position shown in a).Under this state, the internal pressure of raising is eliminated by output products.At this moment, valve film 02 just occupies its original shape and initial position again.This for example is so, and the user recalls the power of bottle extruding so that product is no longer exported, yet this power is still big like this, makes the distortion of bottle also keep.In this state, the volume of this bottle is less than the volume of undeformable bottle.Recalled fully if be used for the power of bottle distortion, the then elastomeric power of resiling influences wall.Because the volume of bottle is reduced in a flash at this, therefore in bottle, produce low pressure.
Illustration b at Fig. 2) first effect of low pressure shown in.Because valve film 02 is still to the areal of support on the stop tab 04 06 and to baffle ring 12 sealings, slight deformation also cannot take place by leaked-in air compensation and valve film 02 in low pressure.Therefore, valve film 02 has very slight the arching upward towards inside.This arches upward under low pressure increase situation constant big, and this is because the peripheral edge region of valve film 02 is yielded to internal pressure.
The illustration c of Fig. 2) valve 01 of peripheral edge region after low pressure is submitted in inside of valve film 02 is shown.Because the peripheral edge region of valve film 02 is not supported and pass through to reinforce or similar structure is strengthened, so only need very little power for this reason.Therefore, by valve 01 according to the present invention, even under very little low pressure situation, also can realize the air resorption.In this resorption position, valve film 02 is lifted away from from baffle ring 12, makes valve film 02 no longer to baffle ring 12 sealings.Therefore, air passes the opening that produced towards internal flow from the outside.This air flows is not interrupted, this be because between valve film 02 and side direction guide portion 13, be provided with around gap 15.Air can be almost unblockedly from the outside to internal flow and remove the low pressure that the there exists.Directional arrow 19 shows air flows.In case low pressure is eliminated fully, squeeze bottle is in its original shape once more.Even the sections in gap 15 still by product to be exported stay partially enclosed, by around gap 15 also can guarantee enough air resorptions.And by resorption, the described part of product is also inner to bottle by resorption.This is equally applicable to the portioned product that stays in the outside of valve film 02, and this is because the there has resorption.
Valve according to the present invention only is made up of two parts in the embodiment that further illustrates before.This has realized simple and the fast speed assembling, and this is because have only valve film to be pressed in the fixed mount by punch.Diaphragm can preferably be made up of silicone resin or similar soft elastic synthesis material, and can be made by harder synthetic material as the fixed mount of injection molding part.
Fig. 3 illustrates the see-through view of the change embodiment of fixed mount 21.For the feature of fixed mount better being shown, not shown valve film.A plurality of support connecting plates 22 are fixed on the stop tab 04, and in the embodiment shown here, support connecting plate 22 is from radially extending the inboard until fixed mount 21 in the stopper 08 of center arrangement.Support connecting plate 22 Priority Service are in the attitude stabilization of valve film, valve film the detent position sectional type of valve place on the support connecting plate 22.In addition, support connecting plate 22 has improved the stability that whole valve is arranged.
Fig. 4 illustrates the change embodiment of fixed mount 21.Be that with the key distinction of embodiment shown in Figure 3 use a plurality of supporting pins 23 and replace support connecting plates, supporting pin 23 is fixed on the stop tab 04.Supporting pin 23 is realized the same function of support connecting plate as described above, promptly at the attitude stabilization of the valve film of valve closure position.Can certainly there be type in other inside of fixed mount, with the attitude of control cock diaphragm and during closed state the attitude of sutaining valve diaphragm.Embodiment and self rigidity according to valve film are provided with many Support Positions for this reason discriminatively.
In the earthquake embodiment, fixed mount, comprise that side direction guide portion and stop tab can constitute integratedly with squeeze bottle or similar containers.
Fig. 5 illustrates the detailed view of embodiment of the distortion of valve film 02.For specific material/medium (it should be discharged from storage container via self-closing valve),, then be favourable if the rigidity of valve film and/or the deformation type under the opening of valves situation can be adaptive.For this reason, reinforcing member 24 is set in the plane domain of valve film 02, reinforcing member 24 for example radially extends and is evenly distributed in the valve film periphery.In the earthquake embodiment, also can be provided with the material weak point, be beneficial to the distortion of diaphragm in corresponding position.
Fig. 6 illustrates the details see-through view of another distortion possibility of valve film 02.At this, profile drip molding 25 is set, in all the other still open cross sections that profile shaped structure 25 protrudes into transport openings 03 or be arranged in the interior wall in the zone of transport openings 03 in the zone of transport openings 03.When discharging medium, be embodied as a burst shaping by profile drip molding 25 by self-closing valve.The profile drip molding that many cooperations are shaped can be set distinctively.Profile drip molding 25 be preferably placed at transport openings 03 on seamed edge outer on the flow direction.And in the earthquake embodiment, the profile drip molding also can further shift to inside on flow direction, and for example interior moulding or the sectional type ground by wall cracks.In addition, this cracking provides following advantage, and promptly diaphragm is easier carries out the transition to transfer position from detent position, and this is because in the fringe region of transport openings 03 alternation of cross-section can take place.
Suitable is, valve is closed cover and hides when withdraw from use, and seal bootr is installed on the squeeze bottle in a known way.
