Description

The vapour-pressure type fluid container

Technical field

The relevant a kind of vapour-pressure type fluid container of the utility model, to be intended to provide according to this creation design goal: a kind ofly utilize the flexible container of inside and outside two-layer equation and cooperate upper and lower valve block interworking, can reach quantitatively, completely cut off multiple utility functions such as (anti-oxidation), backflow and internal stability pressure control.

Background technology

Look into general known soft strip fluid container; As: toothpaste, ointment, mildy wash, emulsus glue, chemicals, emulsion agent etc. all are simple structure kenels as shown in Figure 1, mainly by: a cap A1 and a strip container A 2 are formed; Discussed according to kind and to analyse, 2 saw lumbers of this kind strip container A slightly can be divided into: glue goods and thin metal products two big classes; Wherein with glue system strip fluid container, its occupation mode then is to change the container kenel with the extruding action, and content is a cardinal principle in it in the hope of expelling; After removing the extruding action, this glue system fluid container promptly can restore to the original state automatically; So, with the fluid container of this kind glue goods, there is following disappearance for a long time really:

1, with glue system fluid container, owing to present the characteristic that to recover ortho states; Therefore, after contents, outside air will certainly be sucked the content space of being discharged to fill up; When outside air entered in a large number, its content will inevitably cause oxidation qualitative change effect with air, particularly for some as: products such as medical cream, chemicals and emulsion agent then must influence its safety in utilization and durable keeping quality.

2, because glue system fluid container is to adopt the extruding manner of execution to use, quite careful for then needing in the control of the extruding application of force, careless slightly is not to push that too much to cause waste be exactly to push very few quite being difficult to control.

3, when the content of glue system fluid container in the time will using up, internal tank will certainly residually quite be difficult to the inner capacities extruded, makes this kind container cause significant wastage virtually.

Secondly, look into---with thin metal strip fluid container, be its occupation mode equally with the extruding means, different persons only---be that this kind container does not have the former step response of recovery; Therefore, deposit the following disappearance of tool for a long time:

1, with this kind not tool recover the thin metal strip fluid container of ortho states, end from initially using up until at last, be constantly to change its kenel always, to the last squeeze a ball, on using, being difficult to grip and control, also seem quite coarse and crude in appearance and can't bear, the solid food border that very often has the extruding scrimp to break and leak outside.

2, since this kind not tool recover the thin metal strip fluid container of ortho states, though in the use can be because of moment does not suck a large amount of air, make and severe oxidation qualitative change problem take place in the short time; But the lock demand of joining of cap is still and can not gets rid of, in case cap is lost the oxidation qualitative change that content took place partly of its termination, be equally can prolong and and influence content in it, and then produce safety and durability (as: the emulsifiable paste class in the silica gel in the chemicals, Instant cement and the medicament etc.) on using.

3, since this kind not tool recover the thin metal strip fluid container of ortho states, excessive at extruding exertin so that container deformation, the content in it will constantly flow out in a steady stream and cause significant wastage.

4, when the content of the thin metal strip fluid container of this kind will be used up, except that kenel has become one, internal tank can cause the waste of residual equally and be difficult to extrude use again.

From the above mentioned, no matter be for the glue system strip fluid container of commonly using or the commodity of metal strip fluid container two big classes, all have and improve its renewal necessity, also is required discussion of this case and demand major subjects simultaneously.

The utility model content

Aforesaid inside and outside two-layer equation flexible container is made and can load fluid or breast, aqueous content in it with the soft bag of internal layer; And that outer flexible container is similarly nonrigid plastic is made, only should have the revertible high plastic properties of replying in extrusion back; Wherein, the soft bag of internal layer is with opening ring portion suitable length and the mutual bonding configuration state that is one of outer flexible container top inner edge, see through outer flexible container and impose the extruding action, and then the raising internal pressure promptly can make content discharge function in proper order because of interior pressure relation causes.

The aforementioned oppressed and content that goes out on relativeness is and is limited by the open and close running that valve block implements and controls; Wherein: going up valve block is to adopt the valve plug design, this valve plug can be forced into the open end in outer flexible container when initial the use, forms the integrally-built valve block function that goes up, and this function is or to loosen simple motion with the content pressurized, forms the effect of little property open and close; Particularly---when outer flexible container was removed the extruding action, this valve block promptly can make its natural return closely connected in open end, to obtain the use function that tool is isolated from the outside by little property resorption of internal pressure elimination.

When the valve block in the valve plug operated with open and close, the inner set lower disc of outer flexible container was that the counteragent with open and close is responded equally; This lower disc is an inner face of being located at outer flexible container perforate; When the valve block in the valve plug was opening, lower disc was then because of extruding action and closure state, must make to press in the container to improve, and closed the soft bag of internal layer by compeling of carrying out of the lifting of pressing in this, can obtain ideal and discharge rate is controlled in easy extruding.

On the contrary, after the extruding action was removed, the valve block in the valve plug then was closed condition, and lower disc forms opening because of the inner formed little property resorption of outer flexible container, outside air is entered fill up the content space that is expelled; According to this, constantly repeat this steer mode, will make content can reach in proper order gradually to go out till using up, obtain the fluid container of multiple utility functions such as asking a kind of quantitative, isolated (anti-oxidation), backflow and inner voltage stabilizing control.

Edge is, this creation provides a kind of vapour-pressure type fluid container especially, it directly solves impracticable and numerous disappearances of habit person's strip tool that fluid container is produced in the mode of effecting a permanent cure, most important is to give the simplest a kind of bilayer and the design of valve block open and close, make the formed stable interior pressure advantage of internal tank, can provide this creation to reach thorough emptying content, stable extruding control, quantitatively extrude and SELF CL and multiple use function such as isolated, so that this kind fluid container is more attained to being desirably the final design goal of this case.

Therefore, after this case and prior art are compared, its Different Cognitive and progressive are arranged clearly, its advantage usefulness and the effect that can spread out and, will state by following branch:

1, utilizing this case design can effectively get rid of outside air enters and content generation problem of oxidation; Just be that cap is lost, the valve block in its valve plug also tool is closed isolated function, unlikely its interior all content that influence.

2, this case design is after being entered by the bottom with air, fills up the space of the content of extruding; Therefore, whenever outer flexible container all is to deposit the stable interior pressure of tool, can not make content cause serious waste because of continuously outflowing, and utilizes this stable interior relation of pressing simultaneously, can make extruding control more convenient and simple and easy, and then reach the handy advantage of quantitative extruding.

3, utilize this case design decapacitation to remain in outside the advantage attractive in appearance of glue system strip fluid container institute tool recovery ortho states, be directed in the time of to use up content, then because of the be squeezed relation of power of outer flexible container, make the interior pressure of inner air institute shape tool, can directly oppress in the soft bag of internal layer, make content till using up, have preferable use economic benefit and environmental protection notion.

4, prolong by the 3rd described, press in the outer fluid container institute tool because of this case so, no matter so this case be to be squeezed in any position of container, all can extrude content smoothly, till using up.

5, prolong by the 4th described, when this case can be got rid of strip fluid container content and will use up, the fraud that institute causes effort to extrude; Has convenient, laborsaving and practical multiple advantage.

In sum, the demand of this creation structure bright and clear and simple and the expection can reach, though simply but possess high practicality, its novel and progressive dual important document is also deposited, when also thoroughly solving the variety of issue that habit person's strip fluid container is derived to transform habit person's strip fluid container; Your inspector can further understand the feature and the essence usefulness of this case for ease of, special with embodiment and cooperate graphic being described in detail as follows.

The specific embodiment

At first see also shown in Figure 2ly, the whole kenel of this case is similar with known strip fluid container, and only architectural feature is the peculiar structure of valve block that is specified in fluid container and is cooperated; Continuous please the cooperation shown in Fig. 2,6, this case integral structure mainly by: members such as a loam cake 11, soft bag 12, the one outer flexible container 13 of an internal layer and a plug valve 14 are formed; Plug valve 14 wherein is for joining the assembly of plug formula outward, just join in the opening 131 that is inserted in outer flexible container 13 when use is initial, forming a valve structure function; Design except that can simplifying this case manufacturing course with this, more can obtain and ask easy structure and cost; So, this plug valve 14 is as shown in Figure 4, and the top has a retaining edge 141 and can bridge and be positioned 131 of outer flexible container 13 openings; Interior root edge then be a thin type valve block 142 (annotate: this valve block can be cut in advance be simple valve block function or via the content extruding break through all can), outer peripheral edges then are provided with together or above together ring-type tenon 143, via compeling to fill in outer flexible container opening 131, can be fixed with opening 131 interior set endless groove 132 mutual driving fit tenons; Continuous say simply as shown in Figure 3 that after plug valve 14 compeled to fill in outer flexible container opening 131, this plug valve 14 promptly formed as one with 131 ones of the openings of outer flexible container and makes this skin flexible container 13 so have the structure function of last valve block.

Continuous this case double container structure is to be that soft bag 12 kenels present with internal layer, has the not basic feature of cracky as shown in Figure 6, and can load fluid or breast, aqueous content B in it; And outer flexible container 13 is made with nonrigid plastic equally, only should have the revertible high plastic properties of replying in extrusion back, particularly be positioned at container 13 appropriate locations and offer a pore 133, and, fill up to suck forming two effects greatly with the air that carries out open and close tool that kenel is spread out with internal pressure in the be sticked lower disc 134 of a simple type of pore 133 inner faces; Wherein, the soft bag 12 of internal layer is with the mutual bonding configuration state that is one of top inner edge on opening ring portion 121 suitable lengths and the outer flexible container 13, and content B is isolated with outer flexible container 13 with the soft bag 12 of an internal layer; Simultaneously, this bag 12 then can not brought into play toward top offset effect function with outer flexible container 13 bonding parts, goes out phenomenon to cooperate extruding and the interior pressure that outer flexible container 13 is taken place.

When imposing when being squeezed in outer flexible container 13, content B be limited by plug valve valve block 142 and lower disc 134 both, and controlled with the open and close interworking of being implemented, simultaneously also this two valve block can with by content B pressurized with loosen dual-action, form and have little property open and close running function; When pressurized took place, outer flexible container 13 was pressed relation because of interior contents B in being subjected to, and then will inevitably spread in plug valve valve block 142 and be opening, and content B can see through valve block 142 openings and discharge smoothly; After the extrusion action was removed, 142 relations because of inner resorption power of plug valve valve block are carried out the return lid and closed, and were simultaneously also that the content B and the external world is isolated fully.

Secondly, when plug valve valve block 142 presented the open and close operating state because of extruding and loosening up, lower disc 134 was that the counteragent with open and close is cooperated equally; When tool extruding action, because interior pressure relation, lower disc 134 promptly can SELF CL make the interior pressure of depositing the tool direct ratio with its compressive force in the outer flexible container 13, makes lower disc 134 be closed condition; After the extruding action was removed, outer flexible container 13 and interior contents B discharged formed little property suction, can make that promptly lower disc 134 is opening, can make outside air enter thus simultaneously and be filled up the content B space that expels; According to repeating under this operating mode, content B can gradually go out in proper order till using up, reach quantitatively, multiple utility functions such as isolated (anti-oxidation), backflow and internal stability pressure control.

At last, see also shown in Figure 5ly, the plug valve 14 that this case is designed is can be cone-shaped 144 with bottom design, obtains to ask to puncture the set envelope film of outer flexible container opening 131 and be directed in outer flexible container opening 131 dual usefulness fast; As for, thin type valve block 142 of root edge also can be adopted with split type structure for it in it, to reach equal effect.

In sum, though this case from use on the function, viewpoint opinions such as usefulness, progressive and novelty it, all has certain practical and progressive important document, really meet function enhancement and practical important document that novel patent law is emphasized, after sincerely asking your inspector Yu Xiang discretion to be looked into, vouchsafe this early and create due guarantee, the true feeling moral just.
