The specific embodiment

Be used for illustrating embodiments of the invention, distributor of fluid product comprises a driving gas holder 10 that is formed by a container 1, the bottle that be shaped as a substantially flat of container 1 in Fig. 1-4, it is the

apparent surface

12 and 13 on plane substantially that this bottle forms two, and

surface

12 and 13 is connected to each other for circular periphery 11 substantially by one.Bottle 1 comprises that in addition forms a neck 15, and neck 15 forms the interior pipe 16 that holder 10 is in communication with the outside.Neck 15 comprises an annular upper limb 150 and an inwall of emptying 151.Holder 10 is used to adorn a kind of gas, for example air.But can imagine the gas of other type according to the fluid product that hope distributes.

This special shape of the holder 10 that obtains from a bottle 1 is not unique, in fact, can realize driving gas holder 10 with other shape, and shown in Fig. 5-8, these illustrate a pyriform holder that can push.

In Fig. 1-4, one or best two

plane surfaces

12 and 13 are elastically deformable substantially, therefore can push with two fingers, make them adjacent to each other, for example reduce the volume of holder 10.Therefore, give the gas boosting that is contained in the holder, the effect of doing like this is to make gas pass the pipe 16 that forms a unexpected constriction, and gas inside is quickened.Two arrow P indicate to be applied to the direction of the power on the

startup wall

12 and 13 of holder 10.Certainly imagination reduces other device of holder 10 volumes, for example the piston that can move in the cylindricality that forms holder.

In all embodiments, the

distribution termination

2,2 ', 2 in driving gas holder and the neck 15 that is installed in bottle 1 " be connected.Or rather, the distribution end capitiform becomes the fixed sleeving 24 of a sealed engagement in neck 15.In order to keep the termination well, sleeve pipe 24 forms a raised profile or fixing rib 241, is used for being arranged in the groove 151 that the inwall of neck 15 forms.The termination forms a stop flange 23 on its sleeve pipe 24, stop flange 23 inside radial projection, and contact is blocked on the upper end 150 of neck 15.Termination 2 forms a

cylinder

22,22 ', 22 on this flange 23 ", 22 , the free end of cylinder distributes partly shutoff of antetheca 20 by one, distributes in the antetheca 20 to be drilled with a dispensing orifice 21.Several dispensing orifices 21 also can be set.Distribute the inside of termination to form a groove 25,25 ' that extends in sleeve pipe 24, flange 23 and the cylinder.Groove 25 is unlimited greatly at the free end of sleeve pipe 24, and by the partly shutoff of distribution antetheca 20 that is drilled with dispensing orifice 21.

Distributing box comprises a holder 3 that a kind of liquid or Powdered fluid product are housed.In Fig. 1-4, fluid product holder 3 is formed by a pipe 31 that is bonded in the groove 25, and a wherein end of pipe 31 is by 32 or stopper 32 ' shutoff at the bottom of, and the other end is by the partly shutoff of distribution antetheca 20 that is drilled with dispensing orifice 21.Therefore we can say that the main portion of fluid product holder is made of with the termination 2 that has its distribution antetheca 20 pipe 31 of bottom shutoff.Here holder 3 be shaped as tubular from pipe 31, certainly imagine the holder of other shape.But holder 3 advantageously is tubular, at least in order to be enclosed within the groove 25.In addition, the tubular in shape of holder 3 can form a cylindricality ring 16 in neck 15.Holder 3 also advantageously extends in the neck 15, as seeing among Fig. 1-4, preferably extends in the holder 10 always.Annular 16 forms an annular constriction, is quickened greatly in this annular constriction from the gas-pressurized of holder 10.

In Fig. 1 and 2, bottom 32 can be used with pipe 31 identical materials and form a single component.In Fig. 3,4, a stopper 32 ' is attached on the pipe 31, pipe 31 can be a pipe completely.

Holder 3 can permeate and the impermeable dividing plate of fluid product in the holder 3 at its pipe 31 and/or 32 places, the bottom gas that forms a holder 10.Therefore, the liquid or the Powdered fluid product that are stored in the holder 3 can not be seeped in the holder 10, and be contained in porous or the permeable separator that the gas in the holder 10 can pass holder 3, be driven in the holder 3, therefore drive fluid product and pass dispensing orifice 21, the mode of sentencing two-phase at dispensing orifice 21 atomizes then.In Fig. 1,2 embodiment, can enter into pipe 31 places of holder 3 at pipe 31 places from the gas-pressurized of holder 10, also can enter into holder 3 in 32 places in the bottom.In Fig. 3,4 modification, additional stopper 32 ' is impervious to gas fully, so the gas of holder 10 must pass dividing plate 31 and enter in the holder 3 ', and dividing plate 31 is most of and preferably all be positioned at necks 15.Therefore, force whole gas-pressurizeds to enter in the annular 16, gas quickens in annular 16 greatly.Gas enters into holder 3 with good pressure or power by this way.

With reference to Fig. 5, distributing box that has a container 1 shown in the figure, the global shape of container 1 is a pyriform, its wall 12 places can be out of shape.The inside of this container forms a gas reservoir 10.This container forms a big neck 15, and neck 15 forms a big opening.Unit design and fwd embodiment similarly accept termination 2 ' and are bonded in the neck 15 by its sleeve pipe 24, and are positioned on the neck by its flange 23.This termination 2 ' also forms a dispensing orifice 21 at its antetheca 20 places.Antetheca 20 is that bevelled cylinder 22 ' is connected with flange 23 by a part.Termination 21 ' forms an inside groove 25 '.A convection cell product (liquid or powder) sealing and dividing plate 31 ' that gas can permeate is bonded in the groove is for example snapping in groove 220 places.Dividing plate 31 ' is divided into two compartments to groove, and it is the part of gas reservoir 10 that first compartment forms fluid product holder 3, the second compartments.Therefore dividing plate 31 ' forms an object that extends laterally in the groove 25 ', is used for the support fluid product.

In the 3rd embodiment, the termination forms a diameter or the bigger inside groove of cross-sectional plane.The dividing plate 31 ' that can advantageously show as a simple breaker plate is vertical with the flow direction of gas-pressurized.Therefore, gas more directly passes dividing plate, therefore only runs into seldom load loss and resistance; Therefore the speed of gas at the dividing plate place of holder 3 is enough to the fluid product band to make two phase fluid concentrate the taper of the cylinder 22 ' that points to dispensing orifice also to help this point to dispensing orifice 21 greatly.

The content of describing with reference to Fig. 6-8 below the embodiment of Fig. 1-5 does not relate to of the present invention.But these embodiment comprise the favorable characteristics that can implement with the present invention.

Referring now to Fig. 7 that fourth embodiment of the invention is shown.The container that forms holder 10 can be one with Fig. 5,6 similar or identical designs, promptly be shaped as the pyriform that can push.Holder 10 also forms 15, one of necks and distributes termination 2 " be bonded in the neck 15.This termination also form one be bonded on sleeve pipe 24 in the neck 15, radial flange that is positioned at neck 15 upper ends 23, one be the cylinder 22 of cylindricality substantially ", an antetheca 20 and a dispensing orifice 21.Here cylinder 22 " and the termination 2 that forms of antetheca 20 and sleeve pipe 24 and flange 23 " other parts separate.But it is contemplated that a same embodiment who realizes the termination with the form of monolithic with fwd embodiment.Therefore, cylinder 22 here " and antetheca 20 be shaped as a flowerpot, hole at dispensing orifice 21 places in the flowerpot bottom.This flowerpot is by cylinder 22 " free-ended edge be enclosed within a fixed muffle 220 that substantially in the extended line of sleeve pipe 24, forms around with termination 2 " other parts be connected.The edge contact of cylinder abuts on the radial flange 23.

In this embodiment, distribute termination 2 " comprise that also an inwardly outstanding footpath inwardly encircles limit 26.This radial loop limit 26 is as the supporting mechanism of a spring 33.Spring 33 is used to promote one and is bonded on cylinder 22 " interior piston-follow-up mechanism or scraper plate 32 ".Piston-scraper plate 32 " can permeate and the impermeable material of fluid product is made by a kind of driving gas.But in the embodiment shown in fig. 7, piston-scraper plate 32 ' also can be that driving gas is impermeable, but can permeate and the impermeable dividing plate 31 of fluid product as driving gas " support.Therefore when holder 10 was extruded, the gas that is expelled from holder 10 was forced to pass dividing plate 31 " so that arrive in the fluid product holder 3.Therefore, fluid product holder 3 is by cylinder 22 ', the antetheca 20 that is drilled with dispensing orifice 21 and supporting clapboard 31 " piston-scraper plate 32 " form.Because piston-scraper plate 32 " by spring 33 resiliency urged, the fluid product 3 in the holder 3 is pushed to dispensing orifice 21.Therefore guarantee that dispensing orifice 21 places have fluid product all the time, this is very favourable to the good distribution quality that guarantees dispensing orifice 21 places.Here, piston 32 " and its dividing plate 31 " move to the direction of dispensing orifice 21.But, it is contemplated that piston to another direction, for example laterally act on, but guarantee to provide for dispensing orifice 21 continuously the embodiment of fluid product simultaneously.In fact, piston 32 ", the purpose of a removable wall is the existence that guarantees the fluid product at dispensing orifice 21 places more in a broad sense.Certainly this also can realize by alternate manner.

With reference to Fig. 8, this illustrates the 5th embodiment at last, and this embodiment is the modification of Fig. 7 embodiment.In fact, driving gas holder 10 can be identical, promptly is shaped as the pyriform that can push.One is distributed shape and Fig. 7 termination of termination 2 basic identical.In fact, termination 2 comprise sleeve pipe 24, radial flange that abuts in neck 15 upper ends 23, cylinder 22 , the antetheca 20 that is drilled with a dispensing orifice 21 in the neck 15 that is bonded on holder.Here distribute termination 2 as a whole.

With the same among the embodiment of Fig. 7, the fluid product that is stored in the holder 3 also is pushed to dispensing orifice 21, to guarantee continuously to provide fluid product to dispensing orifice.In order to guarantee thisly continuously to provide, be provided with film 32 of an elastically deformable here, film 32 constitute a part of the removable wall of fluid product holder 3.Film 32 remain on its periphery by a retaining ring 26 ' that is bonded among cylinder 22 .Or rather, the neighboring of film 32 is stuck on the antetheca 20 by ring 26 '.Film 32 can permeate and the impermeable material of fluid product is made with a kind of driving gas, but film 32 preferably as the support of dividing plate 31 , dividing plate 31 can be advantageously located at the center of film 32 .Film 32 have prestressedly, make it can return its dead position naturally.Therefore, the fluid product in the holder 3 bears the pressure that film 32 apply.Fluid product 3 is pushed to dispensing orifice 21 continuously.Be readily appreciated that by Fig. 8 film 32 will turn back to its recline substantially position of antetheca 20.Can expect that film 32 have the plane or smooth form in its dead position.

In the 6th embodiment shown in Figure 6, the shape of distributing box is similar substantially to Fig. 7, has therefore used same reference number.Be with the main difference of Fig. 7, support permeable separator 31 " piston 32 " do not promote by a spring.During beginning, when holder 3 was full of, piston can rest on the sleeve 220.Then, along with the emptying of holder, piston is drifted moving by forced air, and forced air promotes piston, and passes dividing plate.In addition, cylinder 22 " inwall 221 can form a tooth bar that has some otch so that stop piston to return backward.Here the thrust unit of the removable wall of the fluid product holder air that quilt is driven by holder 10 fragmentations guarantees.

In Fig. 6,7, three embodiment of 8, permeable separator 31 ", 31 with can the device that the dispensing orifice 21 of fluid product in holder 3 promoted and shifted onto dispensing orifice 21 places be linked to each other.But it is contemplated that permeable barrier is not to be connected to, to be fixed to the device that fluid product can be sent to dispensing orifice 21, or constitute by this device.But dividing plate preferably moves to the direction of dispensing orifice 21, makes use along with distributing box, driving gas in the fluid product holder through a shorter distance.

Be used for that gas can permeate and the material of the impermeable dividing plate of fluid product can have the structure of a kind of porous, grid, sieve or grenadine according to the fluid product that will distribute.

By the present invention, obtained that a kind of design is very simple, cost is very cheap and the two-phase distributing box of easy-to-use gas/liquid or gas/powder.
