First embodiment:

Please refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4:

The present embodiment provides a kind of check valves, comprising: pedestal 110, elastic container 120 and fixed ring 130；Shape in pedestal 110 At a cylinder chamber of perforation, the inner wall of cylinder chamber bottom is equipped with block machine 111；It is additionally provided among cylinder chamber bottom and block machine 111 The stem 112 being fixedly connected, and stem 112 is additionally provided with the first opening a being connected to cylinder chamber with the junction of block machine 111；Bullet Property shell 120 be set in cylinder chamber, inside formed half spherical cavity；Hemisphere bottom of chamber portion and top, which are respectively equipped with, to be connected to half spherical cavity Second opening b and third opening c；Stem 112 passes through the second opening b and half spherical cavity, and extends at third opening c, with third Be open c fitting；Extension 121, extension 121 and the block machine 111 are extended outward to form at second opening b of elastic container 120 Contact；Fixed ring 130 is fixedly arranged in cylinder chamber, and is in contact with the extension of elastic container 120 121, for consolidating elastic container 120 Due in pedestal 110.

Specifically, above-mentioned check valve provided by the present embodiment can be applied on a variety of extrudable soft packages used, Such as dentifrice tube, Medical ointment tube, eyedrops and skin care item etc..By the mating bottle mouth position for being set to soft package of the check valve, Soft package is squeezed when use, the internal Material contained can enter half spherical cavity in elastic container 120 along the first opening a It is interior, and the cavity wall for converging to double of spherical cavity at third opening c is formed and is squeezed, and expands the elastic container 120, and then third is open Of short duration channel is formed between c and stem 112, and Material is squeezed out from third opening c.When user discharges to soft After the pressure of packaging, elastic container 120 can restore to the original state and with gynostemium 112 by third opening c sealing, outside preventing Boundary's gas enters in soft package.Therefore, the soft package of the check valve is installed, extraneous sky can be completely cut off when in use Gas prevents its internal Material infection or rotten, and when we use every time is not necessarily to take time to exclude air, can directly squeeze out Material, thus more convenient to use.

In one embodiment, block machine 111 is along the molding cyclic annular block machine of cylindricality cavity wall.Specifically, block machine 111 is not It can be only used for support elastic container 120, additionally it is possible to by the cooperation of the extension 121 with elastic container 120, make to be equipped with this unidirectionally Its inner sealing of the soft package of valve is more preferable.And half spherical cavity will be set as in elastic container 120, it can make in soft package When Material receives pressure, stronger to the mobility at third opening c, user is experienced more preferably.

Specifically, fixed ring 130 is fixedly arranged in the cylinder chamber of pedestal 110, is in contact with the extension 121 of elastic container 120, Elastic container 120 can be tightly pressed against in pedestal 110, be guaranteed in actual use, the stable structure of the check valve.

In one embodiment, the inner wall of cylinder chamber is equipped with internal screw thread, and the outer wall of fixed ring 130 is equipped with and internal screw thread The external screw thread worked in coordination, fixed ring 130 are fixedly arranged in cylinder chamber by internal screw thread and external screw thread.

In another embodiment, axially spaced-apart is equipped with multiple grooves, the outer wall of fixed ring 130 on the inner wall of cylinder chamber Multiple protrusions with matching grooves are equipped with, fixed ring 130 is fixedly arranged in cylinder chamber by protrusion and groove.

It should be strongly noted that above-mentioned fixed ring 130 and the fixed form of the cylindricality cavity wall of pedestal 110 are only this Apply for two kinds in numerous embodiments, and in other embodiments between fixed ring 130 and pedestal 110 can also by Nian Jie, The various ways such as socket are fixedly connected, and the application is not specially limited herein.

In one embodiment, the material for making elastic container 120 includes: plastic cement or thermoplastic elastomer (TPE).Wherein, thermoplasticity Elastomer had both had every excellent properties such as the high resiliency of traditional rubber, ageing-resistant and oil resistivity, while but also with common modeling Expect feature easy to process.

Optionally, in another embodiment, pedestal 110, elastic container 120 and fixed ring 130 are plastic material system At, which is made using plastic material, production cost can not only be reduced, and can recycle, raising resource benefit With rate, the pollution etc. to environment is reduced.

Optionally, in one embodiment, stem 112 and the junction of block machine 111 are equipped with multiple is connected to cylinder chamber First opening a.

Specifically, following the description can refer to for the set-up mode of above-mentioned first opening a: first, it can be to guarantee Material Passability, in a certain range expand first opening a, and reduce first opening a quantity；Second, for guarantee stem 112 with The fastness that block machine 111 connects can suitably reduce the size of the first opening a, and be guaranteed by the way that multiple first opening a are arranged The passability of Material.

Optionally, in one embodiment, above-mentioned stem 112 is taper stem.Specifically, taper stem is more conducive to Material inside soft package avoids third opening c place's blocking along the outer wall olderly flowage of stem 112, cause using It is difficult.

In another embodiment, one conical cavity of recessed formation in upper conical stem.Specifically, increase in taper stem Add a conical cavity, can not only save material to a certain extent, reduces production cost, and can be in specific production process Convenient for demoulding processing.Optionally, in above-mentioned check valve, pedestal 110, block machine 111 and stem 112 are integrally formed structures, this Apply to this equally without limitation.

Second embodiment:

As shown in figure 5, the present embodiment provides a kind of soft packages, comprising: packaging shell 210 and any embodiment as above institute The check valve stated；210 one end of packaging shell is equipped with Material outlet 211, and check valve is fixedly arranged in Material outlet 211.

Specifically, the Material contained in soft package can be fluid or lotion, and packaging shell 210 includes but unlimited In: dentifrice tube, Medical ointment tube, eyedrops bottle and skin care item box etc., it is all by squeezing the soft package used, it can be used Check valve provided herein controls its one-way flow to realize, and guarantees that outside air can be completely cut off when in use, prevents Its internal flow or lotion infection or rotten.Moreover, as described in the application first embodiment, we are every time when in use Without spending over head time to exclude inner air, Material can be directly squeezed out, thus more convenient to use.

It should be strongly noted that the set-up mode that above-mentioned check valve is fixedly arranged in Material outlet 211 is only the application One of numerous embodiments, in fact check valve provided herein can be not only embedded in Material outlet 211, can also With setting outside Material outlet 211, and be such as bonded by other, the fixed form that is spirally connected soft package is fixed, the application is herein It is not specially limited.

The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
