Description
Technical field
The present invention relates to boiler check valve and have the liquid accommodating container of boiler check valve.
Technical background
Open clear 60-89143 communique, real opening in the flat 2-83257 communique in fact in Japan, disclosed boiler check valve or bolt structure.This boiler check valve or bolt structure, be elastic body to be set in vessel port, on this elastic body, the slit is set, the liquid that is extruded by pressing in the container that container is applied the external pressure generation etc. opens the slit and opening, when cancelling the external pressure that vessel is applied after liquid etc. has been discharged, above-mentioned elastic body is closed the slit by the recuperability of self.
In last communique, be to form bolt with elasticity or flexible material, the outward appearance of this bolt is a shell shape, inside has vaulted cavity, has at least 1 slit at its front end.
In one communique of back, be to form with elastomeric material to cave in into circular-arc lamellar wainscot, portion has the slit in the central.
But, in above-mentioned prior art, expose outside as valve system key elastic portion portion, that have the slit, so, can meet this elastic portion because of carelessness sometimes.
This elastic portion must have the corresponding elastic force that can prevent slot leakage, if but elastic force is too high, then is not easy to discharge, and the convenience of container reduces.For this reason, do not give its excessive elastic force, still,, except this elastomeric elastic force, do not utilize other any measure for airtight slit, so, make the slit continue to keep being adjacent to, it is not enough only depending on elastic force.Therefore, as shown in figure 13, when on elastic body, having applied any external force, its easy deformation, thus remove being adjacent to of slit, like this, leak of liquid or air in the container are inhaled in the container.
More particularly, present most of tubular container is made with laminated material, owing to itself be elastic body, so the recuperability of vessel is strong.That is, being made by the recuperability of vessel becomes negative pressure in the vessel, and the content material that is expressed into the ozzle peristome is returned in the container again.But, in the above-mentioned last communique,,, but do not take any measure for how preventing the elastic portion contraction though there is measure to make elastic portion not because of pressing over expansion in the container.Therefore, as shown in figure 14, elastic body towards cylindrical portion be crushed, with the open directive effect in slit.
In one communique of above-mentioned back, also produce same situation.That is, when becoming negative pressure in the container, the wainscot in the arc-shaped that caves in becomes and the diametical situation of above-mentioned the former technology, and open easily in the slit.
The said two devices technology is under such situation, and the shortcoming of its aspirated air is more serious than the shortcoming of content leaks.
Like this, in the technology that the slit is used as simple and easy valve before, only be to accomplish in container, to press to allow discharge when high, when interior drops, stop to discharge, and do not prevent that air is inhaled into the technological thought in the container.Therefore, be very simply to construct as valve system, and can not be used for splendid attire food, cosmetics, pharmaceutical chemicals etc. and do not wish to produce and contact with air and the container of oxidized material.
On the other hand, need the liquid of metering, medicine, cosmetics, coating, washer solvent etc. are arranged.
Under the situation that is medicine etc., be mostly that measure certain amount from bottle with jigger uses.In addition, the liquid container of the washer solvent that ampoule is Duoed than medicine, majority are the synthetic resin bottles that bottle cap is used or adopts the pump formula as jigger.The former takes off use with jigger from vessel, though the amount that needs of the First Astronautic Research Institute for Measurement and Test freely is not suitable for measuring accurately.Latter's peristome above plastic vessel is provided with the pump of hand push type, pushes this pump with hand when needing, and discharges content.Like this, the amount of being discharged by a push action of hand almost is certain.
But, have the container of jigger, be content is poured out from vessel to be used facing to being located at scale on the jigger, so, be unsuitable for measuring accurately, and, can overflow because of carelessness when pouring out.In addition, because pouring spout is frequent opening, so, when the content of counting cup meter is used tricks in distribution, can from vessel, flow out the material of unnecessary amount.In addition, do not tighten as operculum, just in case the container overturning, content just leaks out.
In pump formula bottle, the restoring spring of pump is metal, so container is not to be made by the mono-material, promptly enables to constitute with the mono-material, because the cost height also is unpractical.And, particularly improve in the whole society environmental protection consciousness now, can not ignore the problem of garbage disposal.
For this reason, the present invention provides the container that can bring into play the boiler check valve of function conscientiously and have this boiler check valve in order to solve the problem in the above-mentioned technology before, to its objective is.
In addition, container with liquid meter function of the present invention, can solve the problem of above-mentioned technology before, and available mono-material constitutes, simple structure not only, and can prevent unexpected discharge with boiler check valve, and can measure accurately, prevent that the liquid of the above amount of metering liquid from flowing out from vessel.

The specific embodiment
Below, with reference to description of drawings example of the present invention.
Fig. 1 is the stereoscopic figure of expression the present invention the 1st embodiment.In Fig. 1, the 1st, boiler check valve body, the 2nd, discharge orifice, the 3rd, vessel.Fig. 2 be boiler check valve body periphery want portion's skiagraph.
Shown in the (a) and (b) of Fig. 3, (c), boiler check valve 2 is made of cylindrical body 4, valve body 5, crust body 6 and over cap 7 shown in Figure 2.As shown in Figures 2 and 3, cylindrical body 4 forms taper, so that reduce the fluid resistance of vessel side end 8.Cylindrical body 4 also has the function that keeps valve body 5 shapes, and the material of the most handy hardness that is not easy to be out of shape is made.
Shown in Fig. 3 (b), valve body 5 becomes the shell shape of hollow, is provided with slit 9 at its front end.Valve body 5 is formed by the elastic body of rubber etc., and slit 9 is airtight by the elastic force (recuperability) of valve body 5 self under normal conditions.But, when vessel 3 being applied external force with hand squeeze receptacle body 3 grades, container deformation under this external force effect, airtight can easily releasing the in slit 9 under the effect of in container, pressing and become peristome.
Shown in Fig. 3 (c), also has the crust body 6 that covers this valve body 5.Crust body 6 has the function of limiting valve body 5 dilatational straiies.Crust body 6 shapes and valve body 5 but at its front end, are provided with the discharge orifice 2 of normal opening much at one.Crust body 6 the most handy more or less elastomeric materials are made.Discharge orifice 2 cooperates with projection 12 on the lid 11 shown in Figure 2, by both closed contacts, can prevent that the contents (liquid, semi-fluid mass etc.) that remain in the discharge orifice path 20 from contacting and oxidation with air.
Be provided with flange 13 in the outside of crust body 6, as shown in Figure 2, this flange 13 is chimeric with the front end of the cylindrical portion 14 of vessel 3, and is fixed by over cap 7.Over cap 7 screws togather with the screw thread that is located at cylindrical portion 14 outsides of vessel 3.
If be not such structure, but when not having the structure of cylindrical body as shown in Figure 14, because elasticity (recovery) power of vessel 3 makes when pressing to negative pressure in the container, valve body 5 inwards is out of shape, open in slit 9, produce the gap between valve body and crust body, air can flow in the vessel.In addition, if when not having the structure of crust body 6 as shown in Figure 15, valve body just expands, and open hardly in slit 9.Therefore, as shown in the present, 3 functions of cylindrical body 4, valve body 5 and crust body 6 are organically combined.
As shown in Figure 3 and Figure 4, between the medial surface 16 of the front end 15 of cylindrical body 4 and valve body 5 and between valve body front end 17 and crust body medial surface 18, be respectively equipped with space A, B.Space A is the content stagnant area of the path 19 by cylindrical body 4 in the vessel, and its volume is big more, more with power extruding valve body 5 medial surfaces 16 that disperse.The amount of movement of space B decision valve body 5.The above-below direction height C of this space B is big more, and valve body 5 expands greatly more, and the peristome that formation is opened in slit 9 is also big more.These spaces A, B are with path bore D, the discharge orifice bore E of cylindrical body 4 shown in Figure 5, can suitably change according to the viscosity of content, so that carry out discharge rate and discharge the adjusting of easy degree (being applied to the size of the external pressure on the vessel for discharge).
The boiler check valve of the present invention 2 of above-mentioned structure, it acts on as shown in Figure 6.
That is, when giving external pressure to vessel 3 with hand squeeze receptacle body 3 grades, this external pressure make container in press liter, content is extruded towards discharge orifice 2 shown in long arrow among the figure.The content that is extruded enters among the A of space by the path 19 of cylindrical body 4.So the pressure in the A of space rises, the inner face 16 of valve body 5 front ends is pushed outwardly, so, while being dwindled, space B expands, contact with the inner face 18 of crust body 6 up to valve body front end 17.Meanwhile, open in the slit 9 that is located at valve body 5 front ends, and content flows out, and discharges from the discharge orifice 2 of crust body 6 front ends.
When having cancelled the external pressure of vessel 3, slit 9 is by elasticity (recovery) power of valve body 5 and closure, and discharge stops and since valve system especially valve body 5 be closed under the state that is being flooded by content, so air can not enter vessel 3 sides from valve body 5.
When not using, as shown in Figure 7, when closing cap 11, be located at the projection 12 and discharge orifice 2 front end closed contacts of covering 11 centers, blocking-up contacts with air.By making such structure, A has living space in the inboard of valve body 5, even valve body 5 is out of shape towards vessel 3 sides easily, owing to make the equilibrium of pressure between space A, the B that is separated by valve body 5 as far as possible, even in case towards vessel 3 sides be drawn into, slit 9 opens, as long as keep balance, also can get back to normality, slit 9 keeps airtight.Lid 11 itself also can be the with gemel form do not shown of figure, spiral etc. all forms, but no matter be which kind of form except inserted type shown in Figure 7, all must be to be provided with the structure that projection 12 is blocked discharge orifice 2 at the center.
As mentioned above,, the content of discharging from discharge orifice 2 is flowed out continuously from drop by drop dripping, can freely control its discharge mode by regulating bore D, the bore E of discharge orifice, space A, the B of cylindrical body 4.
Fig. 8 (a) to (c) represents to be located at the slit 9 of valve body 5 front ends respectively.(a) be front elevation when being provided with a slit 9.(b) be its birds-eye view.(c) be the skiagraph of slit open configuration.
Fig. 9 (a) is the birds-eye view in the slit 9 of various forms to (e).
In addition, the opening that is located on the valve body 5 is not limited to slit 9, so long as have since press in the container rise opening, the mechanism of the effect of SELF CL when in interior device, press eliminating all can, also can be open pore as described later.
Figure 10 to Figure 12 is that boiler check valve 2 of the present invention is applied in the example on the various vessels 3.Figure 10 is the example that is applied on the plastic bottle, and this plastic bottle is usually used in splendid attire shampoo etc., its vessel 3 deformable under external pressure.Figure 11 is the example that is applied on the wedge shape bag.Figure 12 is the example that is applied on the vertical pouch.Figure 11 and Figure 12 represent bag-like container.Like this, make applying external pressure and to press in producing in the vessel, make on the container of form of ownership of content discharge and all can adopt boiler check valve of the present invention with hand squeeze receptacle body 3.Otherwise, resemble container glass bottle etc., that vessel can not be out of shape because of external pressure, can not adopt the present invention.
Figure 16 to Figure 20 is other example of expression boiler check valve 2 of the present invention.
Figure 16 is that expression has 2 slits.Figure 17 is the structure that expression forms as one cylindrical body 4 and valve body 5.At this moment, can will all form as one with the elastomeric material of rubber etc., also can form cylindrical body 4 with the hard material of plastics etc., the elastomeric material with valve body 5 covers cylindrical body 4 again.Even all form,, just can suppress distortion inwards to cylindrical body part 21 as long as do enough thickly with flexible material, but, preferably cylindrical body part 21 is harder, has the top of peristome if can guarantee to close the needed abundant elastic force of peristome, and then still soft is better.
Each figure expression of Figure 18 extends to the path 19 of cylindrical body 4 and valve body 5 contacted tops, and is branched into 2 strands.At this moment, the peristome obstruction of path 19 is lived at the top 15 of cylindrical body 4 and inboard 16 closed contacts of the leading section of valve body 5.Therefore, as valve system, the slit 9 that is located on the valve body 5 by this partial sum forms the secondary structure.Promptly, shown in arrow among Figure 18 (b), be extruded and the content of path 19 by cylindrical body 4 from vessel 3, valve body 5 is pushed to, between cylindrical body front end 15 and valve body leading section inboard 16, form space A, with should in press valve body 5 and push away and make its expansion on further, slit 9 is expanded, then, discharge from the discharge orifice 2 of crust body 6.Certainly, if having only the former also can give full play to the function of valve, so being located on the valve body 5 also can not be slit 9 but open pore, can be according to the viscosity decision of used liquid.
Figure 19 and Figure 20 are the structures that the expression band is discharged regulatory function.That is, during when opening, along with the rising of pressing in the container, discharge rate changes at valve and discharge orifice, but when make because of carelessness vessel 3 in press when liter waiting, content can penetrate from discharge orifice 2.Therefore, in order to prevent this point, be provided with anti-locking mechanism.Figure 19 (a) is the skiagraph of normality, (b) is the birds-eye view of valve body.Figure 20 (a) is the skiagraph of discharge state, (b) is the skiagraph of closed condition.Arrow is all represented the flow direction of content (liquid, semifluid etc.).
That is, on valve body 5, be provided with the projection 23 that cooperates with the peristome 22 of cylindrical body 4 front ends towards the inboard, when the normality shown in Figure 19 (a), the front opening 22 of cylindrical body 4 cooperates closed contact with the projection 23 of valve body 5, and peristome 22 obstructions of path 19 are lived.Because of press in the vessel 3 rise be extruded and content by path 19 shown in Figure 20 (a), the projection 23 of valve body 5 is pushed to, remove the closed contact of the two.So open in the gap, from flowing out here, the opening 24 around the projection 23 that is located at valve body 5 flows out, and discharges from the discharge orifice 2 of crust body 6 again.
But when pressing further rising in the vessel, shown in Figure 20 (b), the projection 23 of valve body 5 is further pushed to, and is that the front end 17 of valve body 5 contacts with the lower end 25 of the discharge orifice 2 of crust body 6 above it, and discharge orifice 2 is blocked.
By this structure, when only pressing in certain vessel, content discharges.That is, pushed vessel 3 in an unguarded moment and when vessel 3 applied unexpected external pressure, content can not discharged.Therefore, this structure is very suitable when oozing for the needs content, can prevent to discharge continuously.
In addition, the setting that is applied to the pressure amplitude on the vessel 3 that content can be discharged, except the bore E of the discharge orifice 2 of the peristome bore of the bore D of the path 19 of regulating cylindrical body 4 shown in Figure 5 as previously mentioned, valve body 5 and crust body 6, elastic force intensity that can also regulation valve body 5, from the upper end of valve body 5 to the distance of the discharge orifice lower end of crust body 6.At this moment, if must guarantee the volume of space B between valve body 5 and the crust body 6 time, also can projection be set at the top of valve body 5.
Figure 21 and Figure 22 are that expression is located at that the projection 26 at cylindrical body 4 tops cooperates with open pore 27 on being located at valve body 5 and the valve system that forms.The skiagraph of Figure 21 (a) when being normality (b) is the birds-eye view of cylindrical body 4.Figure 22 is the skiagraph of discharge state.
Around the projection 26 of cylindrical body 4, be provided with open pore 22.Be to be provided with 4 open pores in the drawings, but also can be provided with individual arbitrarily.
As shown in figure 22, the content that is extruded in the vessel 3 that do not show of figure, through the path 19 of cylindrical body 4 from the inboard pushing inaccessible the valve body 5 of open pore 22.So the open pore 27 of the valve body of with projection 26 closed contacts of cylindrical body 45 is brought to, the two produces the gap, and content is discharged from the discharge orifice 2 of crust body 6.
Figure 23 to Figure 25 represents different examples.
In the two, valve body 5 all can move in the space B between cylindrical body 4 and the crust body 6.In this example, be provided with spring 28 between valve body 5 and crust body 6, under normal conditions, valve body 5 with cylindrical body 4 closed contacts.
The essential structure of valve system with aforementioned respectively construct identical.That is, Figure 23 represents to be located at front end opening 22 closed contacts of projection 23 and cylindrical body 4 on the valve body 5.Figure 25 represents the projection 26 of cylindrical body 4 front ends and open pore 27 closed contacts of valve body 5.
