Abstract

A container includes a nozzle and body depending therefrom. The body is preferably tubular and defines an interior which retains a product to be dispensed. A cap engages the nozzle to prevent inadvertent release of the product. In order to dispense the product, the cap is removed and pressure is applied to the body and the nozzle allows release of the product. The nozzle releases the product without exposing the remaining product to the external atmosphere, thus the sterility of the interior of the body is maintained and the shelf life of the product is increased. The nozzle includes an inner body, coupled to the tubular body, surrounded by a flexible outer cover. A seam between the inner body and flexible outer cover forms a one-way release valve wherein a portion of the seam remains closed during dispensing the product.

The application is that the application number that proposed on August 13rd, 2003 is PCT/US2003/025487 (national applications number: the dividing an application of patent application 03821754.6).The denomination of invention of original bill application is " be used to store container and valve module with dispensable materials, and associated method ".

The priority application of mutual reference

Present patent application requires the U.S. Provisional Patent Application No.60/403 of submission on August 13rd, 2002 according to 35U.S.C § 119 (e), 396 preceence, its exercise question is " being used to store and the container of dispensable materials and the method for making this container ", the application also requires in the U.S. Provisional Patent Application No.60 of submission on January 27th, 2003,442,924 preceence, its exercise question is " being used to store container and valve module with dispensable materials ", and the full content of these two pieces of documents is contained in this part as the application's disclosure as a reference.

Technical field

The application relates to the container that is used for dispense liquid, cream, paste or similar products, more particularly, but relate to the improved container that comprises check valve and collapsible and/or squeezing tube, its can duplicate allocation be kept at product airtight between matter era and/or aseptic environments in, the invention still further relates to the method for making and using this container and valve module.

Background technology

Flexible hose is used to store various powder, liquid, gel, emulsion and pasty products with different viscosities scope.Usually, this flexible pipe has a lid, can expose a liberation port after this lid is removed.Therefore, need less pressure to extrude content.Unnecessary product seepage and residual through regular meeting's obstruction liberation port.In addition, when opening traditional pipe, content is not only to be exposed in the external environment, and portion of air also can be sucked in the pipe.Therefore, be the technology that food and other products carry out disinfection although adopted, even adopt anti fouling composition, can not avoid the rotten of many kinds of products, therefore carried out assignment constraint the pot-life of product with pipe.Because pipe need carry out repeated dispensing, even if therefore after unlatching, refrigerate the synantexis that also can't avoid product.The pot-life of perishable products is very limited.Consider this point, a kind of be used for less, portable aseptic store method such as family expenses catsup, wasabi and mayonnaise need be provided.

Similarly, many cosmetics, skin disease exterior-applied article, medicine and/or medicine are made up the product product and other material is packaged in distributing box or other container, and these containers are being opened and/or product can be exposed in the air after the allocated product for the first time.Therefore, these products must contain anti fouling composition, and are rotten or in use rotten to prevent the product in the container.In addition, these products generally all must use in the time of opening the relative weak point in back, and are rotten or in use rotten to prevent the product in the container.A shortcoming about anti fouling composition is exactly that it can cause irritated or other bad reaction of user.In addition, anti fouling composition can not prevent a large amount of material aggregation bacteriums in the open container, even grows bacterium in some cases.The distributing box of many prior aries all is exposed to the large-tonnage product that holds in the distributing box in the air after unlatching, just in use and/or after using product is exposed in bacterium, germ and/or other impurity, therefore make that remaining product is contaminated in the distributing box, and in the later use of product, spread germs, germ or impurity.For example, liquid lipstick distributes with the container of prior art with regard to being unsuitable for especially.After liquid lipstick is contaminated,, and finally can't use owing to moisture is lost in airiness, otherwise will before product exhausts, become dangerous.The top is contaminated and become not only dirty but also sticking or harden, and lipstick also can continue to flow when not using simultaneously.

Consider the problems referred to above, worked out several for example containers of the closing appliance of check valve that have.A shortcoming that has the distributing box of check valve in the prior art is exactly that this valve often is designed to use with a mechanical pump or similar actuating device, and these devices can produce higher relatively valve opening pressure.The distributing box example of this type can from the patent No. be RE37047,6032101,5944702,5746728 and publication number be to see the US Patent of US2002/0074362A1, US2002/0017294A1.On the other hand, the distributing box of extruding tubular type can not produce necessary valve opening pressure, and therefore the valve of this prior art can not be applied on the flexible pipe effectively.

Therefore, one of purpose of the present invention is exactly one or more defectives and the shortcoming that overcomes above-mentioned prior art.

Summary of the invention

A preferred embodiment of container of the present invention or distributing box comprises the pipe of a stored prod.This Guan Yuyi mouth of pipe communicates, and this mouth of pipe is used for allocated product from container.This mouth of pipe can be used as a check valve, makes product therefrom to pass through, and prevents that rightabout fluid from passing through.This check valve preferably is made of an inside part and a flexible cover that covers on this inside part, and makes the interface of inside part and flexible cover form a check valve.

Content according to a further aspect in the invention, a kind ofly be used for storing and the therefrom pipe and the valve module of dispensable materials, it comprises a pipe, this pipe has a squeezable body and a head that is positioned on this body one end, limited a storage chamber that is used for holding with stored substance in this body.This head has limited a neck and has extended axially passage with one first that runs through this neck, and this passage communicates with the storage chamber of body, and has determined an axial unobstructive flow channel betwixt.A check valve assembly is installed on the head, it comprises a valve body, this valve body has valve body bottom, its limited one and first extend axially that passage communicates second extend axially passage, thereby form an axial unobstructive flow channel betwixt.This check valve assembly also comprises the valve seat of axially extended a, diameter less than the valve body base diameter, a first roughly taper type or a tapering part that between valve body bottom and valve seat, extends, with a plurality of edges this roughly the taper type section axial extend through the flow export of first, flow export is near valve seat and be in certain angle and arrange at interval.A valve gap is made by a kind of elastomeric material with predetermined elasticity modulus, and comprises a lid bottom that is installed in the valve body bottom, and it is fixed and can not moves axially on the valve body bottom.Cover the diameter of the diameter of bottom, thereby form an interference fit betwixt less than the valve body bottom.A valve portion covers on the valve seat, and has determined an intended radial thickness and the diameter less than valve-seat diameter, thereby forms an interference fit between the two.Valve portion and valve seat have been determined closed usually, annular, an axially extended valve opening betwixt, and valve portion can be radially spaced so that material is being scheduled between the open position of valve opening pressure current downflow mobile at valve portion and valve seat ingear closed contact position and valve portion one section and valve seat.One second roughly taper type or tapering part, it is extending between lid bottom and valve portion, and covers first roughly on the taper type part of valve body, and forms an interference fit betwixt.Can select in these factors of modulus of elasticity of the intended radial thickness of interference degrees, valve portion of valve-seat diameter, valve gap and valve seat and valve gap material at least one come (1) determine one with hand extruding body so that the predetermined valve opening pressure that material is produced when storage chamber flow to the valve opening and (2) thus the gas tight seal valve prevents that in the closed contact position bacterium from entering in the body by valve.

Cap 106 preferably is made of plastics.Preferably, cap 106 can prevent the unexpected seepage of product in the container 100.The person of ordinary skill in the relevant is appreciated that and comprises that also other additional anti-abuse (tamper-evident) feature is to meet the criterion of U.S. food and FAD.Container 100 can also be encapsulated in the box, so that handle and safety.

In order to understand the working process of container 100 best, will introduce the structure and the working process of the mouth of pipe 102 below in detail.Thereby the mouth of pipe 102 discharges this product applying under the situation of a hand pressure on the body 104 with usual manner extruding body, and usual manner is included in and pushes body on the relative two sides in opposite directions, transmits the power of a general radial direction then in body.By the extruding body, the pressure of other material that holds in product or the body increases, and up to the valve opening pressure of this pressure greater than the mouth of pipe 102, just can come product in the dispense container by the mouth of pipe then.The mouth of pipe 102 comprises Outboard Sections or a valve gap 112 and the inside part 114 at far-end or top, and it has the far-end or the top that limit a valve seat, and this valve seat links to each other with Outboard Sections or valve gap 112.This inside part 114 has also limited a near-end that links to each other with body 104.The centre portion of inside part 114 has been determined and cap thread 118 ingear circumferential thread 116.Determined on the proximal part of inside part 114 and body screw thread 115 ingear negative threads 120.

Outboard Sections or valve gap 112 hold inner spout part or end 124, and it has determined the valve seat of inside part 114.As shown in Figure 4, Outboard Sections 112 has been determined a seam 125 with the contact surface of inner spout part 124, its generally be closed (promptly, the inner and outer pipes notch portion is adjacent as shown in the figure), but can be entered and be had enough pressure (promptly in the seam 125, more than or equal to valve opening pressure) product stream wash open, thereby come release products by the mouth of pipe 102.Outboard Sections 112 is preferably molded with the more soft plastic material of a kind of relative inner part 114.Like this, Outboard Sections 112 inner spout part 124 bendings relatively, thus open seam 125, from the mouth of pipe 102 release products.

As shown in Figure 4, inside part 114 has the flange 126 of an annular, and it cooperates with corresponding recess on the Outboard Sections 112, be used for inside part 114 is remained on the Outboard Sections 112, and fixedly Outboard Sections or valve gap can not move in the axial direction.Therefore inside part 114 can be pressed in the Outboard Sections 112, and connects Outboard Sections by this flange 126 is imported corresponding recess.This annular lip 126 can also prevent product unnecessary flowing between annular lip 126 and Outboard Sections 112 basically.As various equivalent modifications can find out, inside part 114 can be integrally molded to the part of body 104.

Shown in Fig. 3 and 4, inside part 114 comprises one first roughly cylindrical side wall 136, and it has mainly determined a hollow shaft that stretches out along container 100 direction of principal axis, and is connected with a joggle with the end of body 104.The proximal part of inside part 114 and centre portion have been determined a first passage 138, and its size shape is designed to align with the outlet 113 of neck 111.The distal portions of inside part 114 has been determined a slightly narrow second channel 142, and itself and first passage 138 are axially aligned.A plurality of liberation ports 140 that are communicated with second channel 142 are arranged on the far-end sidewall of inside part 114, thereby product can therefrom be discharged.In a preferred embodiment, the sectional area of this liberation port 140 is about 60% of this sidewall total cross-sectional area at least; Although the person of ordinary skill in the relevant is appreciated that the liberation port 140 that can also adopt various sizes under the enlightenment of disclosed content, more greatly or smaller, to obtain needed performance.

When process container 100, activate container 100 with hand body 104, product is discharged from the mouth of pipe 102.Therefore, pressure transmits in body 104, first passage 138, second channel 142 and liberation port 140.Pressure helps product to flow to seam 125 from body 104.Therefore, pressurised product flows through liberation port 140, enters seam 125, and the end release that passes the mouth of pipe 102 is then come out.As mentioned above, valve opening pressure is enough low, thereby makes hand extruding body just can produce enough pressure, makes the pressurised product in the container can wash seam 125 open, therefrom distributes.

In case product discharges, and eliminate pressure on the body 104, seam 125 just returns to its closed contact position, anyly is exposed to airborne product stream and gets back in the container 100 preventing fully, and seal this container.Container 100 just is ready to activate once more to discharge the product of another part subsequently.A benefit of this class container 100 is exactly in case discharged a certain amount of product, the seam 125 of the mouth of pipe 102 will be closed, thereby fully prevented to be exposed to airborne product or foreign particle and flowed back to and enter into container 100 through the mouth of pipe 102, this backflow can be polluted the surplus products in the container 100 in some cases.When the reagent combination of the aseptic and/or preservative free that stores many multiple doses, perishables, cosmetics and analogue, above-mentioned advantage is even more important.

With reference now to the embodiment of accompanying drawing 4B,, has an o ring 119 and prevent that product is from unexpected seepage between body 104 and the inside part 114.Preferably, o ring 119 places between container body 104 and the inside part 114, thereby forms a gas tight seal betwixt.Just as can be seen, in this embodiment, the mouth of pipe 102 is that with the difference of the mouth of pipe mentioned above the inside part 114 of valve module comprises one first roughly taper type or bevelled part 127, and it extends between valve body bottom and valve seat 124.In addition, a plurality of flow exports 140 (only showing among the figure) pass this tapering part 127 extensions.Just as can be seen, each flow export 140 is near the valve seat 124 of axial elongation.Valve gap 112 comprises a lid bottom 129, and it is installed on the valve body bottom, and installs regularly and can not relatively move on direction of principal axis by the annular lip 126 of valve body bottom, and this annular lip is contained in the lid bottom and goes up in the corresponding recess.The valve portion 131 of valve gap covers on the valve seat 124.Just as can be seen, valve portion 131 has been determined an intended radial thickness and the diameter less than valve-seat diameter, thereby forms an interference fit between the two.Valve portion 131 and valve seat 124 have been determined a valve opening 125 closed usually, that ring shaped axial extends betwixt.Valve portion 131 can be radially spaced so that material moving radially between the open position of circulating under the predetermined valve opening pressure at the valve portion shown in Fig. 4 B and valve seat ingear closed contact position and one section valve portion and valve seat.Valve gap 112 has also been determined one second roughly taper type part 133, and it extends between valve seat and valve portion 131, and is positioned at first roughly on the taper type part 127, and forms interference fit between the two.

Shown in the dotted arrow 135 of Fig. 4 B, the product that distribute has been determined unobstructive, an axially extended flow channel between body 104 inside and flow export 140.By on the roughly frustum of inside part or tapering part 127, flow export being set, and as shown in the figure by the radially inner side of each opening is set at close or general close axially extended ring-shaped valve seats 124 places, be minimized at the loss in head that produces during 140 allocated product from body inside to flow export, thereby be convenient to produce a relatively low valve opening pressure.Therefore, this container and valve module make product to come easily and swimmingly to distribute from the mouth of pipe by the hand squeezing tube, and this valve module has also guaranteed a gas tight seal, has prevented that fully the intrusion of bacterium or other objectionable impurities from passing valve and entering internal tank.As what hereinafter will further describe, the valve portion 131 of valve gap and taper type part 133 have been determined a taper profile shape, thereby the radial wall thickness that covers these parts is reduced on valve module direction from the inside to surface gradually.As what hereinafter will further describe, in case being exactly product, an advantage of this structure enters sealing or the inner of valve opening 124, the required dynamics of remaining axial part section that continues to open tapering part 133 and valve portion 131 reduces gradually, thereby the material that makes basically all enter the valve opening can distribute by the valve opening, thereby avoids this material residual.Equally as hereinafter further describing, according to currently preferred embodiment of the present invention, basically in any time of carrying out dispensed materials by valve opening 125, each annular section of valve portion 131 and intermeshing of valve seat 124, thus prevent liquid communication between valve outside and the inside.Therefore, valve module preferably can keep the internal tank sealing constantly, even during distribution also can keep sealing, thereby makes container can preserve the product that keeps under aseptic and/or the airtight conditions many multiple doses, necessary, for example prescription of " preservative free ".As described below, with the long enough that extends axially (that is, the sealing surfaces of valve seat) system of valve seat 124, to guarantee realizing this purpose.

Present 5-8 with the aid of pictures shows the embodiment of general another container of the present invention of representing with label 200.This container 200 and previously described container 100 are basic identical, and therefore substituting " 1 " resulting similar label with " 2 " is to be used for referring to similar element in any possible place.Container 200 is that with the key distinction of container 100 inside part 202 and body 104 are an integral body, thereby has eliminated the needs that neck and different inside part are set.

In order to make container 200, baton round is melted when passing extrusion press.Thereby extrusion press can be made the continuous sleeve pipe of a single or multiple lift.This sleeve pipe is cut into required length to form body 204.Should be loaded on the axle by body 204 without a head, this inside part 214 is injected into type, compression molding or weldering thereon on axle, and this is known for the person of ordinary skill in the relevant.Simultaneously, can on the outside face of body, carry out screen printing or overprinting.In body 204, fill selected product then, and Outboard Sections 212 is connected on the inside part 214, to seal this container 200.

For filling containers 200, can provide a charger under the gnotobasis.Can use various types of charger, and a kind of representative type charger is Pack West of 4505 LittleJohn St., Baldwin Park, the liquid-filling machine of CA91706.This product can be expelled in the body 204 before or after the mouth of pipe 202 is in place.After sealing, load onto cap 206 with Outboard Sections 212.Preferably, this cap 206 be used to prevent this product when operation accident extrude.

In an alternative fill method, do not need a gnotobasis, although this product needed is kept in the gnotobasis.Filling process can comprise a kind of pressure is mapped in the container of making by polyethylene terephthalate or by other material that is suitable for sterilization greater than sterilant atmospheric, for example liquid hydroperoxide.In order to remove this bactericidal agent, one hot filtrated air stream can quicken its evaporation process.Then, this sterile product installed to replace hot air in the container, but up to sucking-off part sterile liquid, thereby guarantee that entire content all is aseptic.At this moment, can carry out suitable sealing with the form of the aseptic mouth of pipe.For other adoptable fill method and device, can be according to U.S. Patent No. 6,351,924, U.S. Patent No. 6,351,924 and/or U.S. Patent No. 6,355,216 enlightenment comes this container is filled, this in conjunction with the full content of above-mentioned patent with as a reference.

In another embodiment shown in Fig. 8 B, a container has the inside that a flexible shoulder 290 comes sealed tube body 204, with isolated with outside atmosphere.Just as can be seen, the end of body 204 is radially outward spaced apart with respect to the bottom of inside part 214, thereby between has been determined a charging hole 291 that is generally closure state.This flexibility shoulder 290 has been determined the sealing member 293 of an annular, and it extends inward between the bottom of inside part 214 and the body 204 in the formed space vertically.This flexibility shoulder 290 is preferably made by an elastomeric material, and it closes with adjacent inside part 214 bottom connections under normal condition, thereby between forms seal a fluid or air tight hermetically-sealed construction.In pouring process, a filling element (not shown) moved to or, perhaps moves on in the opening 291 by opening 291, then with product with being pumped into wherein, shown in arrow " a ".Therefore, sealing member 293 is radially bent, break away from the bottom of inside part 214, open inflow entrance 291, make product therefrom flow to the inside of container along the filling element (not shown) or the product stream of arrow " a " direction.After the can, sealing member 293 returns to the closed contact position, seals this inflow entrance 291, thus the product in the airtight container.Just as can be seen, since the far-end of sealing member 293 or medial extremity with respect to its root radially to interior orientation, so the pressure that the sealing part can not produced owing to from the mouth of pipe allocated product time is opened, can in pot-life of this container and use, keep airtight conditions on the contrary always.Shown in the dotted line among Fig. 8 B, after can, a cap or other closure 295 can be fixed on this shoulder 290, thereby prevent that any objectionable impurities unexpectedly is incorporated into inflow entrance 291 and enters internal tank.This closure 295 can adopt multiple different, current known or that in the future learn, the structure that can realize this function, and this closure preferably can prevent abuse, if thereby anyone has destroyed sealing when lid really, this destruction be clearly and this container also scrapped.Those of ordinary skill in the related art can recognize according to the enlightenment of this paper, can also use multiple person of ordinary skill in the relevant filling apparatus and method now known or that learn in the future, and these equipment and method can be used to can various containers of the present invention.

See accompanying drawing 9-12 now, show the embodiment of general another container of the present invention of representing with label 300.This container 300 is basic identical with previously described container 100 and container 200, therefore substitutes " 1 " with numeral " 3 " and is used for referring to similar element in any possible place with " 2 " resulting similar label.Container 300 is that with the key distinction of container 100,200 structure of the mouth of pipe 302 is different.

The mouth of pipe of describing with the front is the same, the mouth of pipe 302 can by be fit to arbitrarily, durable, mouldable certain flexible material makes, for example a kind of plastics, preferably form by a kind of material of the specific products compatibility that fills in special and the container of having found, Connecticut, USA state Fairfield (Fairfield, the VELEX that General Electric company Connecticut) is had for example

Trade mark and LEXAN

Product under the trade mark, the perhaps KRATON that had of Kraton Polymers U.S.LLC

Product under the trade mark.The inside part 314 of the mouth of pipe 302 preferably is molded as a global facility, comprise a body part 313 (Figure 12) that cuts taper type or truncated cone, being a post or valve seat 317 on the one end, is a shoulder or cylindrical wall 336 on the other end.Preferably, this body part 313 to be becoming the direction location smaller or equal to miter angle with respect to the axis of container 300, thus the loss in head minimum when making allocated product.In a preferred embodiment, the angle of this body part 313 is about 30 degree.This shoulder 336 has been determined the axial flow channel 348 of a diameter greater than styletable 317.(not shown) in another embodiment, the diameter of this styletable 317 be greater than the diameter of axial flow channel 348, thereby increase the size of flow export, and correspondingly reduce required valve opening pressure.Those of ordinary skill in the related art can recognize according to the enlightenment of this paper, the diameter of mouth of pipe valve seat disclosed herein (radial dimension or lateral dimension) can be adjusted according to the one or more of following condition: such as the radial wall thickness of the valve portion of the interference degrees between valve gap and the valve seat, valve gap and the modulus of elasticity of valve gap material, thereby can realize a required valve opening pressure.One or more inside that guarantee that valve module can airtight container as described below, as also can to select these variablees, and prevent that bacterium or other objectionable impurities from entering in the pipe from valve.

12A-C with reference to the accompanying drawings, preferably, illustrate as the front, extending axially partly (promptly of valve seat or styletable 317, sealing surface between valve seat and the valve gap) long enough, thereby any time that can be during distribution, the various piece and the valve seat of valve gap are meshing with each other, to prevent to be kept at circulation mutually between product in the container and the ambient atmosphere.This styletable 317 has and is designated as three zones of 1,2,3.First area 1 is the part that valve gap 312 blocks flow export 340.The 3rd zone 3 is zones that material is discharged from container 300.Second area 2 is the zone lines between first area 1 and the 3rd zone 3.Each zone 1,2,3 has related pressure P1, P2, P3 separately.When static, each pressure P 1, P2, P3 equal zero.When squeeze receptacle 300, shown in Figure 12 B, on first area 1, produce certain pressure, leave styletable 317 up to the part of valve gap 312.Material flows in the second area 2, the pressure in second area 2 and the 3rd zone 3 is raise, wherein P1＞P2＞P3.Shown in Figure 12 C, material was introduced into the 3rd zone 3 before amount discharge container 300, and valve gap 312 comes back on the first area 1 of styletable 317, to keep sealing state, prevented containment ingression container 300.Along with the release of material, relative pressure dependence is as follows: P1＜P2＞P3＞0.

The same with other embodiment of valve module disclosed herein, valve gap 312 is preferably determined a section thickness (or radial wall thickness), and this thickness is along reducing gradually from the inside to surface on the axial direction of valve module.Thereby, typically shown in Figure 12 A-12C, valve gap has been determined a bevelled shape of cross section, its axial direction along valve inwardly is tapered in addition from the inside to surface, as described below, the contact surface between valve gap and the valve seat can be determined a radial interference that reduces gradually from the inside to surface along the axial direction of valve module, promptly, the radial interference degree of valve gap and valve seat area 1 is greater than zone 2, and can also determine the radial interference degree of zone on 2 greater than zone 3 on the top of the mouth of pipe.Therefore, turning on the required power of each section of valve gap reduces from the inside to surface gradually along the axial direction of valve.Therefore, in case opened the bottom section 1 of valve, material enters in the seam or valve opening of common closure, and the elastic behavior of valve gap and valve module structure mentioned above will make valve gap self return to the closed contact position gradually, thereby force a certain amount of material axially to pass this seam.In addition, valve gap forces the flow of material outlet spout top in the valve, thereby prevents material aggregation in valve, and avoids producing on later time point residual leak.

As clearly shown in Figure 12, flange 326 and tapering part 313 coaxial settings, and axially stretch out from it.In a preferred embodiment, this tapering part 313 is to cut taper type.This flange 326 helps to keep Outboard Sections 312, and produces a containment surfaces that covers on the flow export 340, thereby reduces and prevent the residual leak of material.An annular recesses place 319 is arranged between tapering part 313 and flange portion 326.Can admit that this tapering part 313 and flange 326 can fashion into an integral body, also can mould respectively.Similarly, inside part 314 also can be integral body or different assemblies with body 304.Tapering part 313 comprises a centre hole 342, and it is by the internal communication of axial flow channel 348 with body 304.These centre hole 342 1 ends have a plurality of liberation ports 340, and product can pass through this liberation port axial flow.Container 300 comprises three liberation ports 340, and it is arranged around the equidistant mutually basically interval of the axis of the mouth of pipe 302, and on cross-sectional plane, liberation port 340 determined areas are greater than the area of residue entity part.Yet those of ordinary skill in the related art can recognize that the mouth of pipe 302 can comprise this liberation port any requirement, any required arrangement according to the enlightenment of this paper, and this depends on application and other needs of distributing box.In a preferred embodiment, the layout of liberation port can be at least 50% of an annulus area, most preferably between about 70% to about 90%.

Lid Outboard Sections 312 can be made by any durable, elastomeric and flexible material, and it has required modulus of elasticity, is for example made by a kind of elastomeric material.Preferably, Outboard Sections lid 312 is formed for example a kind of KRATON by a kind of thermoelastic material

Styrene-butadiene elastic body under the trade mark.Other nonrestrictive Available Material comprises polyvinylchloride, from the APEX FLEXALLOY of Teknor Apex company

Material, from the SANTOPRENE of Advanced Elastomer Systems

Rubber and butyl rubber.In a preferred embodiment, inside part 314 is by KRATON

Material is made, and its modulus of elasticity is about 4.1Mpa, and enclosing cover 312 is by SANTOPRENE

Material is made, and its modulus of elasticity is about 2.6Mpa to 4.1Mpa.Outboard Sections lid 312 comprises a mounting portion 321 and a tapering part 323, and it is with inside part 314 combineds action, to form a leakproof one-way valve.An annular recesses place has been determined in mounting portion 321, with tapering part 313 and flange 326 engagements, thereby connects Outboard Sections lid 312 thereon.Because Outboard Sections covers the elastic behavior of 312 materials, it is bigger that inside part 314 can be made, to form a resilient interference fit.In one embodiment, Outboard Sections lid 312 fashions into identical size with inside part 314, and the demoulding contraction of Outboard Sections lid 312 has formed required interference fit.

The size of valve gap or Outboard Sections 312 be configured as after installing can with inside part 314 Elastic Meshing, thereby make tapering part 323 and styletable or valve seat 317 can between the two, form a check valve that is generally closure state.As mentioned above and illustrate especially in Figure 12, the tranverse sectional thickness of tapering part 323 reduces from the inside to surface gradually along the axial direction at mouth of pipe end or top.Therefore, open the required pressure of valve seat and also reduce gradually, thereby help product is discharged by check valve, can prevent that again air or other gas from passing this check valve the other way around simultaneously.Preferably, general toroidal section of Outboard Sections lid 312 and styletable 317 engagements in whole allocation process, thereby between pipe inside and external environment gas tight seal of formation, shown in Figure 12 A-12C.If desired, also with above-described the same, also can the tapering part 323 of valve gap and the interference degrees between the valve seat 317 be reduced from the inside to surface gradually along the mouth of pipe by the internal diameter that changes Outboard Sections lid 312 and/or inside part 314.Preferably, a cap (not shown) is connected on the screw thread 316 of inside part 314, with sealing orifice 302, prevents that the accident of product from extruding.

With reference now to Figure 13-15,, therefore the mouth of pipe 402 and foregoing Cyrtophorina seemingly substitute " 1 ", " 2 " with digital " 4 ", " 3 " resulting similar label is used for referring to similar element in any possible place.An advantage in the structure shown in

embodiment

300 and 400 is exactly that product can flow along a basic straight flow channel, and this passage is along extending with the direction of container 300,400 parallel axes.This flow channel relatively more directly and smoothly makes product to flow out by the mouth of pipe 302,402, and has less loss in head, and this makes and only need use less power when allocated product, and it is residual in the space to prevent to produce the non-ground that needs of product.

In addition, what the external diameter of valve seat 317 can be provided with is big as far as possible, thereby reduces essential valve opening pressure, and this pressure must produce when extruding body 404, comes allocated product with open valve and by valve.The present inventor recognizes that multiple factor can influence the response pressure of valve, comprises the interference degrees between modulus of elasticity, valve gap 412 and the valve seat 417 of diameter, valve gap 412 of valve seat 417 and the thickness and the shape of valve seat 417.When other factor all equated when all, the volumetric flowrate that material passes valve can become greatly owing to the increase of valve seat 417 diameters, thereby required valve opening pressure can reduce.The inventor recognizes and required is: (1) compares the diameter that increases valve seat 417 with the valve of prior art, with the valve opening pressure that reduces to certainly lead to when the extruding body; (2) compared with prior art reduce the loss in head of product stream when valve; (3) reduce product at the valve of flowing through carrying out the elastic energy that the branch timing is stored in valve, thereby can reduce the residual leak of product in valve.A remarkable advantage of valve shown in Fig. 9-15 and additional embodiment described here is exactly that flow export 440 has been determined a flow channel that is basically parallel to container axis, thus the loss in head minimum that product stream is produced when valve.

Therefore, the person of ordinary skill in the relevant is understood that on the basis of reading this paper disclosure can select valve-seat diameter, the interference degrees of valve gap 312 and valve seat 317, in these factors of modulus of elasticity of the intended radial thickness of the valve portion 323 of valve gap 317 and valve gap 312 materials at least one come (1) determine one with hand extruding body 304 so that the predetermined valve opening pressure that material is produced when storage chamber flow to valve opening 340, (2) thus gas tight seal valve 302 prevents bacterium or other objectionable impurities or impurity on the closed contact position enter in the body 304 by valve 302.

In another embodiment shown in Figure 15 A, valve seat 417 from the mouth of pipe 402 always through the inside of body.Valve body 414 has been determined a plurality of flow exports 440, itself and valve seat 424 angled extensions, and and separately between the angled interval of entity part arrange.In currently preferred embodiment of the present invention, valve body has been determined the flow export 440 of three angled extensions.As implied above, this flow export 440 preferably runs through 60% of its place anchor ring, most preferably runs through about about 70% to 90% of its place anchor ring.Typically shown in Figure 15 A, the lap that the interference degrees of valve gap 412 between valve seat 424 can be by cross-hauling significantly as seen from the figure.Just as can be seen, between valve gap and valve seat, exist largely and interfere, thereby can guarantee on the closed contact position, to produce the required distortion of sealing.In the embodiment of Figure 15 A, as mentioned above, valve seat 424 has been determined a bevelled end, and the valve portion 423 of valve gap has been determined a bevelled cross sectional shape.Those of ordinary skill in the related art can recognize according to the enlightenment of this paper, valve seat can adopt multiple not isomorphism type arbitrarily, comprise that a kind of straight shape or the diameter that passes through are constant, perhaps a kind of pyramidal structure or other distressed structure are to reach some performance standard or to realize other purpose.

The difference that depends on product viscosity can change the structure of the mouth of pipe 402, obtaining required valve opening pressure, and guarantees that it can produce firm distortion to carry out gas tight seal on the closed contact position.For example, enclosing cover 412 can have different interference level and modulus of elasticity, and these character can influence valve opening pressure, promptly at the required stress of circumferencial direction open valve.With reference to figure 15B, it schematically shows the axial component of valve gap 412, comes to determine valve opening pressure according to the following equation:

Δa = \frac{q}{E} \cdot \frac{2 {ab}^{2}}{a^{2} - b^{2}}

Δb = \frac{qb}{E} \cdot \frac{a^{2} + b^{2}}{a^{2} - b^{2}} + v

σ_{2} = \frac{q b^{2} (a^{2} + r^{2})}{r^{2} (a^{2} - b^{2})}

{\max σ}_{2} = q \frac{(a^{2} + b^{2})}{(a^{2} - b^{2})}

Work as r=b

Solve q:

q = \frac{ΔbE}{b \frac{a^{2} + b^{2}}{a^{2} - b^{2}} + v}

The q substitution can be got:

{\max σ}_{2} = \frac{ΔbE (a^{2} + b^{2})}{b \frac{a^{2} + b^{2}}{a^{2} - b^{2}} + v (a^{2} - b^{2})}

Q=unit pressure (power on the per unit area) wherein; The a=outside radius; The b=inside radius; σ ₂Stress on the=circumferencial direction; The E=modulus of elasticity; V=Poisson's ratio (approximate 0.4); The variation of Δ a=radius a; The variation of Δ b=radius b.By these formula being applied to five position A of Figure 15 A, B, C, D on the E, can calculate different parameters.Based on these formula, Table I has provided the example data of Figure 15 A embodiment five position A-E in Figure 15 A.

Material is made.Yet the person of ordinary skill in the relevant can recognize that these hardness numbers are only used for also can changing these hardness as required to satisfy the needs of some performance standard or other situation for example.

In Figure 18, show the embodiment of general another container of the present invention of representing with label 600.This container 600 is basic identical with container 500, therefore is used for referring to similar element in any possible place with the resulting similar label of numeral " 6 " Alternative digital " 1 " to " 5 ".Just as can be seen, container 600 comprises a top area 611, and it has a roughly profile of vertebra platform shape, is used for suitable or suitable substantially contact user's face or other skin area.Those of ordinary skill in the related art can recognize according to the enlightenment of this paper, the shape on mouth of pipe top can adopt current any multiple different shape and/or structure known or that learn in the future, to carry out the function on mouth of pipe top, comprise suitably or the required certain surface areas of alternate manner ground contact.

In Figure 19, show the embodiment of general another container of the present invention of representing with label 700.The mouth of pipe 702 of this container 700 is basic identical with the above-mentioned mouth of pipe, therefore is used for referring to similar element in any possible place with the resulting similar label of numeral " 7 " Alternative digital " 1 " to " 6 ".For the sake of simplicity, hereinafter only the difference of container 700 bodys 704 is described.Body 704 has an elastomeric outer wall 760 and is sealedly connected on outer wall 760 bottom 762 bottom.The cross-sectional plane of outer wall 112 is suitable for the user and grips with hand, and with a kind of elastoplast for example low density polyethylene (LDPE) make, thereby outer wall 112 can be sealed with other assembly of container 700.Those of ordinary skill in the related art are appreciated that molding, extrude or method that other similarly makes container 700 assemblies all can be exchanged, bonding, heat-sealing, interference fit and similarly combined method also can be used for assembling vessel 700.

Bottom 762 is sealedly connected on outer wall 760 bottom.Preferably, the size of bottom 762 and structure are designed to make container 700 to shelve thereon in upright mode.Connection for bbreather pipe 770 is used for being adjusted between the inner and inner bag 764 of outer wall 760 in the formed space 772 airflow flowing back and forth.Deflation hole 774 on the bottom 762 makes extraneous air to enter in the space 772 by connection for bbreather pipe 770 after one is distributed circulation, thereby makes outer wall 760 return to a plurality of stepped serrations shape again.When squeeze receptacle 700, air needs enough just can make slowly space 772 to produce pressure from the discharge process of deflation hole 774, and finishes assigning process before the air of aequum runs off.On the contrary, when unclamping extruded tube, need enough air and enter in the space 772, so that outer wall 760 fast quick-recovery original-shapes by deflation hole 774.A ring 776 is set around the connection for bbreather pipe 770, influences the work of connection for bbreather pipe 770 to prevent inner bag 764.

Flexible inner bag 764 holds product, and is fixed on the upper limb 766 of outer wall 760.In addition, inner bag 764 is affixed to the inboard of outer wall 760 on the point 768 of outer wall 760 about midways location, applies too big power on the outer wall 760 and just can empty inner bag 764 substantially fully to guarantee to not be used in.Preferably, inner bag 764 is made by a kind of material of low elastic modulus, thereby need not to apply too big power when the product that distributes its inner space 765 to be held.

The mouth of pipe 702 optionally and is airtightly opened the inside and the isolate from outer air of inner bag 762.By preventing that air admission is in the inner space 765 of inner bag 764, the mouth of pipe 702 has not only guaranteed the aseptic of inner space 765, also be convenient to carry out the next one and distribute circulation, also not need not to push with strength outer wall 760 and can not produce significant bubbling (appreciable belching) situation.In assigning process, extruding outer wall 760 makes it produce distortion, with the pressure in the increase space 772, thus the pressure in the inside 765 of increase inner bag 764.Although portion of air can be discharged by deflation hole 774, pressure still can overcome the engagement of valve gap 712, thereby the product that makes as indicated above flows out from flow export 740.After removing squeese pressure, assigning process has just stopped.Outer wall 760 begins to return to the preceding original-shape of distortion, thereby produces a vacuum in space 772.This vacuum state forces connection for bbreather pipe 770 to be opened, so that extraneous air enters by deflation hole 774, thereby inner bag is moved to the mouth of pipe 702, makes outer wall 760 recover shapes.Therefore, in the process of next time pushing outer wall 760, the mouth of pipe 702 is opened rapidly once more, with a kind of leak free mode release products once more.repeatedly discharge a certain amount of after, inner bag 764 is crooked near intermediate point 768, all dispenses in 765 internally up to nearly all product.

In another embodiment, outer wall 760 is made by a kind of material of relative rigidity, makes outer wall 760 distortion and/or helps to produce the required power of pressure thereby increased.Therefore, the mouth of pipe 702 can be designed to have bigger response pressure.Those of ordinary skill in the related art can recognize according to the enlightenment of this paper, container 700 can adopt any multiple structure of container at an easy rate, for example a kind of flexible tube that above illustrates and connection for bbreather pipe can be positioned on any a plurality of suitable positions, and these all are nonrestrictive.
