The specific embodiment

Fluid product dispensing device according to the present invention mainly comprises three element, i.e. bellows type parts 1, actuating device 2 and a housing or shell 3.

Bellows type parts 1 are monomer members, and it for example is to make with the deformable flexible material of neoprene or thermoplastic elastic thing etc.In the interval that suitably limits, this member has good deformable characteristic.Bellows type parts 1 have a diapire 11 that is essentially rigidity.Described diapire 11 can be accurate plane, but also can be convex shape shown in Figure 3.

From Fig. 3 as seen, diapire 11 has formed a kind of shape that is similar to round dome or inverted cup cap, and normal cup cap is then to upper process.In its outer periphery, formed at least one displacement tab 13 on the diapire 11, it is rigidity basically.In the example shown in the figure, be provided with three such tabs 13.

Also formed a retaining collar 15 that is essentially rigidity on the bellows type parts 1.By way of example, can form the fastening depression 16 of inlay card type of a close no leak in the retaining collar 15, it is used for matching with the complementary member that hereinafter will introduce.Bellows type parts 1 also have a deformable leg 14, and it couples together retaining collar 15 and diapire 11.For example, can become thickness by Thickness Design, and make leg 14 have deformability leg 14 less than diapire 11 or retaining collar 15.Thereby, deform by making leg 14, the mode of diapire 11 with translation can be moved to retaining collar 15.More definite, as can finding out from Fig. 2,3, deformable leg 14 has formed a scrimp, if apply the pressure that is tending towards the collar 15 is shifted to tab 13 on this leg, just can make this scrimp more obvious.Saying definitely, is because this deformable leg 14 makes parts 1 have the bellows type functions of components, just makes parts 1 energy Cheng Qiwei bellows type parts.Certainly, also can consider to form deformable component with other device, for example, available flexible bag replaces bellows type parts 1, and this bag is fixed on the bag strut member, and this strut member can play the effect of retaining collar 15.Diapire 11 can be replaced by a plate, and flexible bag just is landed on this plate.Can utilize the peripheral part of the plate that is supporting flexible bag to form displacement tab 13.It is also contemplated that other embodiment, for example can adopt a piston follower, it is slidably received within the cylinder barrel.

In embodiment shown in the drawings, actuating device 2 comprises one section lining 20, and its inside is shaped on thread, thereby has formed one or more helical or guide groove 21.As can be seen from Figure 3, the displacement tab 13 that is positioned on the bellows type parts is screwed onto with described helical 21.Below the lining 20 that is shaped on screw thread, formed a clamping-action element 23 on the actuating device, the user can grip this element and come rotary actuators.Optionally design is: formed a diapire 22 on the actuating device 2, it preferably is used as a diapire of dispensing device.Be shaped on a plurality of sections 24 of a continuous projection edge strip or a continuous edge strip on the outer wall of helical lining 20, the expanded range of edge strip has covered the whole girth or the part girth of lining 20.Be readily appreciated that: when bellows type parts 1 are maintained fixed motionless state,, tab 13 is moved in the lining 20 that is shaped on helical as rotary actuators 2.

The housing 3 of dispensing device has constituted a kind of containment structure, and the outward appearance of dispensing device depends on described shell to a great extent.Housing 3 is provided with periphery skirt cover 33, and the lining 20 of actuating device 2 is disposed in this skirt cover 33.In embodiment shown in the drawings, the inside of skirt cover 33 is provided with the depression 34 of an annular, and the projection edge strip sections 24 on thread bush 20 outsides is received in this depression 34.The edge strip sections 24 that is engaged in the depression 34 has guaranteed that lining 20 is remained in the skirt cover 33 rotationally.Like this, actuating device 2 just can overlap in 33 at skirt and freely rotate, but can not deviate from from the skirt cover.Because each sections 24 and the depression 34 of edge strip are accurate circular, but not helix line, so can freely rotate.

Above skirt cover 33, formed a plate 31 on the housing 3, on this plate, be shaped on a hole, it is as the dispensing eyelet 32 of dispensing device.Extend a coupling bush 35 from the below of plate 31, it is around dispensing eyelet 32.Coupling bush has constant type exterior feature, and it engages with the sealing and fixing collar 15 on the bellows type parts 1.Thereby, even bellows type parts 1 are connecting when it rotates with housing 3 also fastenedly.The result is exactly, and bellows type parts 1 and housing 3 cooperatively interact and formed the container 12 of a variable volume, and the reason that the volume of this container can change is removable wall 11 can be moved to plate 31 owing to utilize the distortion of leg 14.Accompanying drawing has been represented just to be rotated and situation that 3 whiles of housing are taken place when keeping motionless when actuating device 2.For example, the user holds housing 3 with its left hand, utilizes the right hand to hold actuating device at clamping-action element 23 places simultaneously, comes rotary actuators 2 with this.The effect of this operation is that displacement tab 13 is risen in the interior helical of lining 20.Like this, removable wall 11 just moves up to plate 31, has just reduced the actual displacement of container 12 simultaneously.Thereby the fluid that will be stored in the container 12 transfers out through dispensing eyelet 32, and then, the user just can use the fluid that collects on the plate 31.

In this embodiment, by being assembled into housing 3, bellows type parts 1 constitute container 12.But, also can consider to adopt other embodiment, in these embodiments, container 12 is made by a monomer members, and this monomer spare for example is the bag of a flexibility, and the perforate on this bag has formed dispensing eyelet 32.In the case, plate 31 will be just as an abutment surface and as the receiving surface that is used to collect fluid.

Optionally scheme is: can make a top cover 36 on housing 3, it links into an integrated entity by the remainder of a bridging material 37 with housing 3.Thereby bridging material 37 has constituted a hinge, its make top cover 36 can with respect to skirt overlap 33 and plate 31 pivot.Be shaped on a shutoff pin rod 38 on the bottom surface of top cover 36, it is suitable for being inserted into hermetically in the dispensing eyelet 32, is used for airtightly that it is airtight.When top cover 36 is turned over when being incorporated on the plate 31, just can realize above-mentioned effect downwards.

Utilize dispensing device of the present invention, just can obtain quantitative fluid, the dispensed amounts of fluid is with directly proportional to the degree of rotation of actuating device.
