The specific embodiment
Now, the present invention will be described with reference to above-mentioned accompanying drawing.Beautification product, gel or cream type article that having moderate tack to the flowing product of high viscosity for example needs secluding air to preserve are stored in the variable volume liquid reserve tank, and this variable volume is corresponding to the amount of stored goods.United States Patent (USP) 5 152 434 has been described this type of liquid reserve tank in the distributor for example, and this distributor comprises by liquid reserve tank to be supplied with and by the pump chamber of moveable piston restriction, this liquid reserve tank is arranged in cylinder.
In unrestriced mode, moveable piston (20) is supplied with the relative arrangement of opening (21) with liquid and is slided in cylinder (22), and cylinder (22) and piston (20) have defined liquid reserve tank (2).Liquid reserve tank (2) is supplied with pump chamber (3) by the supply opening (21) with check-valves.This check-valves prevents that flowing product from flowing to liquid reserve tank (2) from pump chamber (3), and makes flowing product flow to pump chamber (3) from liquid reserve tank (2).In unrestriced mode, piston (20) comprises the lower screwed hole (23) that is used to fill liquid reserve tank (2).Screwed hole (23) is sealed by stopper (24) then.When liquid reserve tank (2) was sky, screwed hole (23) can be used as suspension hook, is used for piston (20) is pulled out outside the cylinder (22).The substrate of cylinder (22) will for example be placed the top and will be extended by the element (25) that receives pump with respect to liquid reserve tank (2).Supplying with opening (21) for example is formed in pump chamber (3) and the shared dividing plate of the substrate of the cylinder (22) of liquid reserve tank (2).
In unrestriced mode, described non-return supply valve comprises removable dish (41), and this dish is arranged in pump chamber (3) and the close opening (21) of supplying with.In the process that pressure increases in pump chamber (3), remain near the dish (41) of liquid supply opening and move and be placed in immediately on the supply inlet (21) with the liquid that flows to liquid reserve tank (2) now.So just, prevented the circulation of liquid to liquid reserve tank (2).In unrestriced mode, described removable dish is soft and comprises arm (421,422) in its outer rim, and described arm has definite width and thickness having elasticity, thereby permission dish (41) is close to and is supplied with opening (21) and settle.Static dish (41) keeps and supplies with between opening that minimum distance is arranged.In unrestriced mode, the arm of described dish (421,422) is straight as shown in Figure 9, or is serpentine as shown in figure 10.
According to another example, there is the resilient disc of slit to be placed in the pump chamber, and is supported on the support that is arranged in supply opening (21), wherein there is the each several part of the resilient disc of slit to move away described support, pass through to allow the fluid pump.This has the dish of slit for example to be positioned in the extension of wall of pump chamber, and this wall is by making with dividing plate shared at the bottom of the casing base, and this dividing plate comprises supplies with opening (21).There is the thickness of the dish of slit to determine for example its resilient property.
Pump chamber (3) is partly formed by the member with elastic diaphragm, and this elastic diaphragm is molded to single part.This diaphragm element comprises the mid portion of for example being made by the deformability plastic material (44), collapsible/accordion shape that this mid portion is made into.This mid portion (44) (being also referred to as barrier film) for example is compressed under user's action and owing to its resilient property is returned to non-compression position.This intermediate elastic portion (44) for example prolongs on a side by the support cylinder ring (43) of being close to cylinder (22) substrate.This cylinder ring (43) is for example around supplying with in the cylinder/cylinder shape groove (housing) (26) of cylinder (22) that opening (21) is embedded in liquid reserve tank.In unrestriced mode, as shown in Figure 2, collapsible/accordion type is being widened and become to cylinder ring (43) with mid portion (44) joint, and this collapsible/accordion type has formed soft membrane, is used for the insertion force of diaphragm element is applied to the groove of liquid reserve tank cylinder (22).
In unrestriced mode, be used for sealing the single part that the removable dish (41) of supplying with opening (21) is made into to have diaphragm element by its resilient support arms (421,422).Support the elastic arm (421,422) of removable dish (41) for example to be connected to the inwall of cylinder ring (43), this cylinder ring is inserted in the groove (26) around supplying with opening (21).
The elasticity mid portion (44) that forms barrier film with collapsible/accordion shape for example is lengthened to and the relative opposite side of liquid reserve tank (2) by the reception ring (45,46) of elastic valve, and this will describe after a while.The ring (45,46) that receives elastic valve comprises the cylinder (45) that for example is implemented in the radial support on this valve.Cylinder (45) for example is extended by the flat crown (46) (flat crown) of determining thickness, and described thickness is limited by the excircle that belongs to this cylinder (45).Flat crown (46) is subjected to being formed for discharging the inner periphery restriction of the outlet of liquid.Elasticity mid portion (44) for example reconnects the reception ring (45,46) of valve on the level of its crown (46).Crown (46) allows the cross-brace of valve.This valve for example is supported on the wall that receives ring, and the wall of this reception ring forms shell in the mode of sealing.In unrestriced mode, the reception ring (45,46) that cylinder in the groove (26) of the cylinder of liquid reserve tank (22) inserts ring (43), elasticity mid portion (44) and valve is made into by the rotation around the central axis of diaphragm element.
The example of elastic valve only is presented among Fig. 5, Fig. 6 and Fig. 7 in unrestriced mode.The valve that is placed in the exit of pump chamber comprises towards pump chamber (3) the dome part (51) that slit is arranged in addition.In infinite mode, dome part (51) comprise be used to make viscous liquid passes through one or more than a slit (F).For example, two slits (F) intersect at the place, summit of dome part (51).
Advantageously, the dome shape of these parts (51) of outlet valve is sealed this pump chamber by the suction that prevention enters in the pump chamber (3) in aspiration procedure.Suction in the pump chamber (3) clamps to have the part of slit and it is close to each other, and dome part (51) suffers restraints also by tightly closed.On the other hand, in the process that pressure increases in pump chamber, owing to be applied on the dome part (51) towards the thrust outside the pump chamber (3), the dome part (51) that slit is arranged of outlet valve is opened.Described slit has for example produced the be clamped together different piece of (sealing) of outwards disengaging movement or maintenance.When static, the elasticity of outlet valve is tended to again the closed dome part that slit is arranged.In unrestriced mode, dome part (51) has camber profile or annulus section shape as shown in Figure 5 and Figure 6, or have as shown in Figure 7 a bell profile.
In unrestriced mode, dome part (51) is extended by locating ring (52) at its outer rim place, perhaps be extended by the neck region, and this neck region further is extended by locating ring (52).
For example shown in Figure 6, neck region (59) comprise two gradually narrowing portion branches, and these two gradually narrowing portions branches close by the side edge of its minimum diameter.This neck region is connected with dome part (51) in a side, and is connected with locating ring (52) at opposite side.This neck region (59) with definite thickness that is connected to dome part (51) has determined for example elasticity of outlet valve.
Have the dome part (51) of slit to be connected to locating ring (52), this locating ring receives in the ring (45,46) by supported being clamped in of its outer rim.In the pressure increase process, dome part (51) is opened in pump chamber (3), and locating ring (52) is clamped by the reception ring of diaphragm element afterwards.In aspiration procedure, locating ring radially and laterally is supported in the groove of diaphragm element.
Keep closely at the locating ring of diaphragm element and the abutment that receives between the ring.Locating ring (52) prolongs to the direction relative with pump chamber (3) by the sleeve (534,535,536) that inserts in the dispensing head, thus the sealing between the outlet opening of the outlet of generation pump chamber (3) and dispensing head.
In unrestriced mode, as shown in Figure 5, locating ring (52) radially prolongs by the arm (58) that supports a bar (57), and this bar (57) is disposed in the pump chamber (3) and towards the removable closure disc (41) of supply opening (21).The arm (58) that supports described bar (57) and be disposed in the pump chamber (3) for example distributes around this bar (57), is furnished with between the wherein continuous arm (58) to be used to interval that liquid is passed through.When barrier film was compressed, bar (57) produced and for example makes removable dish (41) be close to the support of supplying with opening (21).Like this, at the end of stroke, the closure of supplying with opening (21) is by being arranged in the barrier film and the bar (57) under dome part (51) is guaranteed.In unrestriced mode, distributor comprises the blocking element that is in compression position, keeps embedded dispensing head to allow the user to unclamp by blocking element.Afterwards, bar (57) is supported on the removable dish (41), the closed thus opening (21) of supplying with.The blocking element that is in compression position will be described hereinafter.
The outer wall that the sleeve (534,535,536) of prolongation locating ring 52 is close to the tube portion (65) that belongs to dispensing head (6) by its inwall is supported.Sleeve (534,535,536) for example extends thick end (54,56) or bent back ends (56), to guarantee the sealing between sleeve (534,535,536) and the tube portion (65).This tube portion partly is connected with the outlet of formation pump chamber (3) with dome part (51) in a side, and is connected with outlet (61) at opposite side by outlet opening (612).This dispensing head comprises for example outer cylinder (63), and this outer cylinder is positioned near the tube portion (65) and with the radial distance of determining and removes, to hold the sleeve between outer cylinder (63) and the tube portion (65).In unrestriced mode, the spatial accommodation of this sleeve narrows down at its end, with the end (54,55) of closing sleeve.The end of this sleeve for example is gradually narrow and widens outside sleeve towards its end.The reinforcement (64) that is arranged in the sleeve shell along the outer cylinder (63) of dispensing head for example forms the neck region in the end of the spatial accommodation of sleeve.Thus, the end of sleeve (54,55) is clamped in its shell, and the inner surface of sleeve is arranged to the outer surface of the tube portion (65) of being close to dispensing head.
According to another example, as shown in Figure 7, sleeve (534,535,536) comprises the end (56) to the sleeve inner bending.This end (56) for example is made very meticulous, so that extension also clamps this tube portion (65) tightly near tube portion (65).
In unrestriced mode, as Fig. 4 and shown in Figure 11, dome part (51) is arranged near outlet opening (612).The summit of dome part (51) for example is positioned in and the terminal identical level place of sleeve (537,537) and the inwall of close dividing plate, stayed surface (S6) outside the top of formation dispensing head.The volume of the inner space of the distributor between outlet of pump chamber (F) and the outlet opening (611) is minimized thus.
In unrestriced mode, the end of sleeve is broadened and surpasses the height of determining, with by its terminal this sleeve of strengthening, goes up applied force thereby transmit by the user at dispensing head top (S6).This sleeve with this force transmission to the locating ring (52) that is supported on the diaphragm element that bears compression stress.Similarly, when the user unclamped dispensing head, diaphragm element was by elastic dilatation and rely on locating ring (52) and sleeve with the dispensing head pushed home.In unrestriced mode, the dispensing head of being supported by its outer rim (62) is static by the position of mild compression at barrier film and sealing wheel rim.
According to another example, the outer cylinder of dispensing head (63) comprises the interior shoulder (66) that directly is supported on the diaphragm element.As shown in Figure 1, shoulder (66) is supported on the end of the reception ring of valve (45,46) for example.Afterwards, sleeve is sealed on tube portion (65), and need not at non-compression position transmission compression and restoring force.
For example, outlet (61) stops outside dispensing head by dispensing orifice (611).Outlet (61) is by stopping on the side of outlet opening (612) in dispensing head that is centered on by tube portion (65).In unrestriced mode, dispensing head is by cylinder dividing plate (25) transverse guidance, and this dividing plate has extended the substrate of the cylinder (22) of liquid reserve tank.The end of the outer cylinder of dispensing head (63) comprises the wheel rim (62) that for example points to outside the dispensing head, and this wheel rim points to that inner wheel rim (251) is relative to form locking with going up at the cylinder dividing plate (25) of the cylinder (22) that extends liquid reserve tank (2).
In unrestriced mode, comprise on the external component of dispensing head in being directed into guiding cylinder (25) being used at one of the compression position locking or more than a latching.This dispensing head for example is rotated so that described latching is placed in respectively in the L shaped groove, and guiding cylinder (25) was set at compression position with the height corresponding to the latching position in this L shaped groove was close to.
The user for example is supported on the upper surface of dispensing head (S6) and goes up to push barrier film.Afterwards, pump chamber (3) is compressed.Be closed with the check-valves of supplying with the relative arrangement of opening (21).Pressure in the pump chamber (3) increases, and has the dome part (51) of slit to open, and passes through with the flowing product that allows to be assigned with.The decline of dispensing head causes flowing product to pass through dispensing orifice, flowing pipe part (65) and passes through outlet (61) and discharge.
Afterwards, to its resting position, barrier film arrives extended position by elastic recovery to this distributing equipment by elastic recovery, thereby forms the suction in the pump chamber (3).The each several part of dome part (51) gathers together near slit or a plurality of slit, thus valve is positioned at the exit of pump chamber (3), promptly is in the close position.The dome shape helps to stop better the each several part of the dome part (51) that closely supports mutually.Removable dish (41) is pushed back from supplying with opening (21), thereby the flowing product that allows to derive from liquid reserve tank (2) is sucked in the pump chamber (3).In unrestriced mode, the piston (20) of liquid reserve tank (2) is close supplies with opening (21), thereby reduces the volume of liquid reserve tank (2).
Advantageously, the valve that is arranged to pump chamber outlet is made into single molded parts, with as diaphragm element.Pumping and sealing guaranteed, this be because these two parts are mounted together and with dispensing head and liquid reserve tank acting in conjunction.The different piece of the parts that identical molds is molded for example will have the elasticity by its thickness determined.For example, locating ring will have than the bigger portion's section of dome part, thereby more firm.The material that is used to molding will comprise for example plastic material or polymer or rubber.In unrestriced mode, the closing lid of outlet is provided, it is fixed by clamping or tightening on the dispensing head.
Will it is evident that for a person skilled in the art the present invention allows the embodiment of numerous other particular forms, and not deviate from the application of the present invention for required protection.Therefore, it is a kind of illustrating that current embodiment only should be considered as, but can be changed in the field of the scope defined of the claim of enclosing, and the present invention and nonessentially be limited to above given details.
