Figure 20 has schematically shown the free-ended various embodiments of draft tube to Figure 22; And

Figure 23 shows a mode utilizing pump in accordance with the present invention.

Embodiment

Fig. 1 schematically and with perspective fashion has shown that the product that is provided with pump in accordance with the present invention 2 stores and distribution container 1.

In the position that Fig. 1 shows, assembly has to be presented at and is assumed to be vertical locational whole axis X-X '.

Shown in example embodiment in, container 1 comprises bottom 3 with sealing and the cistern that forms the open top end 4 of neck, by for example turn pump 2 is installed on described neck.

For example, container is used to hold cosmetic product or care product.The makeup product will be interpreted as ATSC Advanced Television Systems Committee instruction (Commission Directive) product that 93/35EC limited as on June 14th, 1993.

Yet, if being included in the container 1 or by pump 2, distribute any other fluid, liquid or thickness product, do not constitute and depart from the scope of the present invention.

As can be seen from Figure 1, pump 2 mainly is made up of draft tube 5, draft tube 5 comprises lower end 6 and relative top 8, the product that is included in the container 1 enters in the pipe 5 by described lower end, and described lower end extends in the container towards the closed bottom end 3 of container 1, particularly, lower end 6 contacts with the end wall 7 of container, and container is extended on described relative top and product is assigned with by described top when it leaves pump.

When static, pipe 5 cross sections that advantageously have constant dimensions.This cross section advantageously is circular, but can similarly be polygonal also, especially, and for square or oval.This cross section can have the size between 3mm and 15mm, is diameter especially, more preferably between 8mm and 12mm, in particular for about 10mm.

The lower end 6 of draft tube can extend into the end wall of container and contact, or maximum end wall 10mm away from container.

Pipe 5 can utilize fastening piece to be installed on the container.This fastening piece can relate to pinch plate rail fastening (clip-fastening), screw threads for fastening or crimp rings (crimping ring), to be installed on the neck of container as drive fit.

For example, pipe 5 is provided with threaded collar b in the middle, and described threaded collar is threadably fastened to the neck of container, therefore for example will manage 5 by friction and remain on suitable position.

Container can alternatively be provided with the lid (not shown) on the top that is coupled to pipe.

With reference to Fig. 2, the mode of pump work is mainly based on making the pumping head distortion that forms by the come-at-able part 9 of the hand that extends to the pipe 5 outside the container 1.

Therefore, draft tube 5 is made by deformable material at least in part, is in particular part 9.For example, for the pipe of the external diameter of internal diameter with 10mm and 14mm, utilizing the stiffness constant of the pipe that texturometer (texturometer) axially measures is 4000N/m.Yet, irrelevant with internal diameter and external diameter, the stiffness constant of pipe advantageously at 3000N/m between the 6000N/m, with the adaptability that guarantees pipe with work effectively.

Pipe 5 and part 9 are as a part production.

Advantageously, pipe 5 is made as a part by the extruding flexiplastic.Alternatively, this pipe equally can (for example, roational molding or injection-molded operation be produced by molded operation.

Yet, produce the advantage that pipe also has by extruding and be, allow to produce very long pipe, for example, greater than three centimetres pipe, especially, greater than eight centimetres pipe, even more particularly for greater than 12 centimeter length and have the pipe of constant diameter.

Pipe 5 is a single-walled pipe advantageously also, that is to say there is not the pipe of sleeve pipe or outer wall.Preferably, all parts of pump are all made by a kind of material (for example, one or more plastics) of and same type.

In example embodiment illustrated in figures 1 and 2, by catch pipe 5 in the part 9 that forms the pump housing, to produce distortion with hand, particularly, produce distortion by (for example, between thumb and the forefinger) crimping section 9 between two finger D with (arrow F1) power of applying on radially inner direction.

As can be seen, Fig. 2 has shown the operating principle of pump in Fig. 2, can manually operated regional 9 be that 10 bottom valve and label are that 11 overhead-valve is divided the boundary line by label, this bottom valve and this overhead-valve make it operate on identical direction in the face of locating each other mutually.

Be noted that in this because pipe is made as a part, particularly, because this pipe produces by pushing, so can produce the draft tube in the zone of the elastically deformable that has the boundary line of dividing suction chamber and also assemble valve seat S.

Shown in example in, bottom valve and overhead-valve are formed by for example having the valve of the spherical valve type of the ball of B, when static, ball B rests on the valve seat S.Each described valve all is positioned to manage in 5 in the following manner, described mode is for when being applied on the pipe by the elevated pressure that produces for the power of transverse force in the case, so that cause when causing the local final distortion that reduces of cross section, a valve (promptly, bottom valve 10) closes, and another valve (that is, overhead-valve 11) is opened (arrow F2), and the product of doses distributes by overhead-valve 11 and then arrive pump discharge (arrow F3).

After allocated product, when releasing tube 5, the zone 9 of elastically deformable turns back to its initial position.Final absorption is closed overhead-valve 11, and bottom valve 10 is opened, and finally fills the deformable region 9 of draft tube.

In other words, the elastically deformable of draft tube 5 and can be manually operated regional 9 constitutes the variable capacity suction chamber of axially dividing the boundary line by bottom valve and overhead-valve, this suction chamber can be by partial compression, so that reduce the volume of this suction chamber and make the product of doses obtain to distribute, discharge suction chamber subsequently and make this suction chamber turn back to its initial volume, so that allow product to enter owing to make the elasticity of the wall of pipe.Therefore, the lower end 6 of pipe 5 requires to be the upstream of suction chamber, and top 8 extends to the downstream of suction chamber.

Therefore, those of ordinary skill in the art will be by the made pipe that can easily be out of shape by hand, and particularly, suction chamber can turn back to its initial position in the undesirable actuating that can not allow pump, the product of suction simultaneously, all these is based on the character of the product for the treatment of suction.

As previous demonstration, utilizing extruding to produce pipe is favourable making the production of pipe (production of suction chamber particularly) provide in the scope to the better control of the dosage of allocated product.

In this, can select to have less than the shore hardness of 45D and less than the material of the bending modulus of 200MPa.

As an example, pipe 5 can be made by synthetic rubber (elastomer), and for example, the synthetic rubber of SBR or CR type for example exists

Or The EPDM that sells down of trade (brand) name or the synthetic rubber of EPM type, for example exist

Polysar

Buna

Or

The FPM that sells down of trade (brand) name or the synthetic rubber of FKM type, for example exist

Or

The synthetic rubber of trade (brand) name MQ, MVQ, MPQ, FVMQ or the FMQ type sold down, for example exist

Or

The synthetic rubber of the EVM type sold down of trade (brand) name, for example Levapren,

Synthetic rubber or alternatively be AU or EU type.

Can also adopt by the thermoplasticity synthetic rubber of TPO or TPV type and make, for example,

Or

The synthetic rubber sold down of trade (brand) name or the synthetic rubber of SBC, TPU, PEBA type or based on the synthetic rubber of second propylene (propyleneethylene), for example at Multiflex

Or

The synthetic rubber sold down of trade (brand) name.

Yet, can also similarly adopt by the flexible thermoplastic plastics of EVA or VLDPE type and make, for example,

Escorene

Or The thermoplastic sold down of trade (brand) name.

The layout that has illustrated makes can to produce in fact by inside and is provided with the pump that the draft tube of bottom valve and two valves of overhead-valve is formed; divide the boundary line of suction chamber between two valves; therefore; pump can be used the parts production of lesser amt, and this advantageously has influence to its manufacture cost and environmental protection problem.

In addition, because pump with the parts production of lesser amt, therefore makes with the quantity of the kinds of materials that must the circuit fluid contacts minimizes.In addition, as will describing in detail after a while, in it uses, have the flexibility of broad by with hand draft tube being out of shape to come actuated pump to make, thereby allow various operations to select, and further allow especially quietly operation.

Therefore,, can make the suction chamber distortion in a different manner for one and same pipe, for example, by making this suction chamber elongation, twisting, pass through this suction chamber of friction etc. by making this suction chamber.

Should be noted that in use the product volume of distribution depends on the degree of pipe distortion.Particularly, the dosage of the product that distributes by pump equals the variation of the volume that causes by the mechanically deformation that is applied to flexible pipe.Therefore, can when once using another time use, transmit different dosage according to user's demand, and if be fit to, a large amount of products transmitted.

Yet be further noted that, in described example embodiment, pipe can be installed on the container by fastening piece, alternatively, also mounting pipe in the following manner, described mode is that this pipe is directly contacted with the inwall of neck, makes neck will guarantee by friction and is held in suitable position to obtain the sealing assembling, can omit retaining ring like this.

Should be noted that at last top 8 can be provided with distribution member in order to make the easier use of pump.On this aspect, as shown in Figure 1, the pipe 5 with distributing head 12 can be set, for example, described distributing head is pushed in the top 8 that is coupled to pipe so that distribute easilier, has particularly improved precision.Particularly, distributing head can be included as the conduit of little cross section, perhaps can match with the ozzle that is provided with the whirlpool induction system.

Certainly, alternatively, the applicator of other type or distribution member also can be installed on the top of pipe 5.Type such as porous member, spin can be used in this respect.

Certainly, the present invention is not limited to described embodiment, and other embodiment is presented at Fig. 3 in Figure 23.

Yet among the embodiment of the explanation that formerly sees figures.1.and.2, pipe is out of shape by manual squeezing pipe between two finger D, with reference to Fig. 3, can assemble the pump head with pump actuator.

Yet, should be noted that suction chamber extends to the outside of container at least in part in these different embodiments.In other words, when wanting to operate by hand, the user can easily be placed on his or her finger on the suction chamber of elastically deformable, so that activate this suction chamber with hand.Similarly, when using actuator, this member is installed in the outside of container in the following manner, described mode is for making if fault, then this member can be changed,, then this member can be changed if perhaps have the needs that any change activates the mode of suction chamber.

In the example embodiment shown in this figure, pipe is provided with clip P, and two branches 13 of clip P and 14 local rings are thorny come-at-able regional 9, and can described two branches be close to together so that manage lateral deformation with hand (arrow F4).Clip P can be by avoiding preventing that the material of filling the elastically deformable of suction chamber from making.Alternatively, because the flexibility of pipe, clip can be made with material rigidity, indeformable, and described material has the articulated type connection (articulation) of returning position of rest at the place, release position.

In addition, in the example embodiment that has illustrated, pipe alternatively, can also be designed to by this canal curvature is deformed (arrow F5) as shown in Figure 5 and Figure 6 by extrusion-deformation.

In this embodiment, in fact only different with the embodiment who has illustrated on the mode of actuated pump pressure head, only need the position of rest returned along the axis X-X ' of container in fact from pipe, on the free end 8 of pipe, apply lateral force so that this canal curvature, thereby the part that is created in cross section reduces, and finally causes the volume of suction chamber to reduce.

For example, the free end of pipe then can be provided with the fixed stop of producing with the form of release portion (relief) 15, so that actuated pump pressure head more easily.Yet alternatively, the mouth of container particularly, is divided the inward flange in the boundary line of this nozzle part opening, can be by forming the surface that activates suction chamber in this some place collapsible tubing.

According to Fig. 6 and the 3rd alternative form shown in Figure 7, suction chamber upward is out of shape by it being reversed to apply torsion moment to pipe.Thereby this can be undertaken by warping force being applied to the last volume that also reduces suction chamber of pipe.As can be seen from Figure 6, pump head can then be equipped with protuberance (tab) 16, so that the easier warping force (arrow 6) that applies.

Below with reference to Fig. 8, alternatively, pipe can be by being out of shape its elongation.

In other words, in the time of on pulling force being applied to pipe, final distortion causes reducing along the cross section of suction chamber, and makes product pass through overhead-valve 11 distribution.

On the contrary, when releasing tube, suction chamber turns back to its initial position (arrow F7), thereby causes suction in suction chamber, makes overhead-valve 11 close, and bottom valve 10 is opened (arrow F8), and sucks product by bottom valve 10 (arrow F9).

With reference to Fig. 9, in order to make easier elongation pipe, elongated piece can be arranged on the ring b, this member comprises trigger 17, trigger 17 comprise with hand be generally the first end regions 17a that activates on the direction of laterally (arrow F10), securely be connected to pipe free end 8 the second end regions 17b and against or be connected to the intermediate portion 17c of the pedestal 18 that is fixed to ring B.

In this embodiment, be distributed on the direction of the whole axis X-X ' that is transverse to or favours in fact pipe in fact and carry out, suction chamber constitutes by this way, is inserted in the groove of making in the pedestal 19 and the bend pipe that is directed in described groove so that form.

For example, in this embodiment, the second free end 17b forms fork-shaped portion, shelves the flange of making near the free end of pipe 5 20 in the described fork-shaped portion, particularly, is the surface of the flange on the opposite side of the end that is positioned at pipe 5.As a result, when exerting pressure on the first end regions 17a, the 17b of fork-shaped portion is with lateral force or be generally tilting force and be applied on the flange 20, and the result causes the elongation suction chamber.

This distortion that causes by elongation makes the cross section of pipe reduce, and causes the product of distribution corresponding to the dosage of the size of amount of deformation.

Then discharge, the elasticity of pipe makes suction chamber be filled on the one hand, reorientates trigger in its initial position on the other hand.

As what illustrated, in described various embodiments, suction chamber is divided the boundary line by bottom valve 10 and overhead-valve 11.As can be seen, each all is made up of overhead-valve and bottom valve spherical valve in the embodiment of Fig. 1, Fig. 2 and Fig. 8.

In the case, as shown in figure 10, valve comprises body 22, described body has roughly cylindrical outer periphery surface and is provided with the closed end of one or more passages 23, and the inside of described body comprises the housing that holds ball B, described housing is divided boundary lines by closed end 23 on the one hand, on the other hand by ball B when valve is shown in an open position institute against annular seating 24 division boundary lines.

Yet, replace spherical valve, can use groove valve (Figure 11), the wherein mushroom valve (Figure 12 and Figure 13) of the displacement disc 25 closed product flow orifices that keep of the lateral branching (for example, 26) by elastically deformable or the clack valve (Figure 16) that alternatively uses gate valve (Figure 14), the needle-valve (Figure 15) that gate wherein can translation moves or alternatively use gate wherein to pivot equally.

Yet, should be noted that (for example, make by flexible synthetic rubber by flexible material for valve in Figure 12 and embodiment shown in Figure 13.Have the shortcoming of the limitation of producing although it is so, but can keep producing very simply.

In the embodiment of various designs, make product enter entering in the internal volume that valve 11 can be arranged on container in the chamber, and the delivery valve 10 of allocated product can extend to the outside of container, that is to say, extends to beyond the neck of container.

Should be noted that in this as mentioned above, suction chamber extends to the outside of container at least in part.In other words, draft tube comprise in the internal volume that is inserted in the container and therefore drops on container and extend to the part of mouth and be projected into container with and the outer outer part of container of mouth.This projection can be used to connect actuator.

At least interior section can be at least at more than 50% of its length, preferably at more than 75% of its height, and more preferably on its whole height, do not cover sheath or outer sleeve, make on its height in the pipe that pipe will be inserted into product contacts, can increase to product being kept at the volume in the container.Be also contemplated that to the exterior section of education and correction for juvenile offenders and do not have covering.Pipe can not have covering on its whole height except the height of distributing head attachment portion.This partially or completely do not have covering to make can to avoid with container in the product that contained produce potential physical-chemical and change, particularly, all the more so when this covering is made by metallic material.

To Figure 19, with regard to overhead-valve 11, alternatively, the second end 8 of suction chamber can be with the form production of self-enclosed outer peripheral wall (that is the wall that seals in position of rest (Figure 17 and Figure 18)) with reference to Figure 17.On the contrary, when producing elevated pressure in suction chamber, open naturally so that fluid flows this end.When discharging suction chamber, the end of suction chamber will be closed naturally once more so that product flows in this chamber.

In the various embodiments that are contemplated to shown in Figure 16, preferably to add the form production of part, described interpolation part is inserted in the draft tube 5 and by friction, clamping or press fit and remains in this draft tube valve at Figure 10.The actual advantage that has reducing cost and increase the convenience of use of this embodiment.
