Definitions

  • the invention relates to a discharge device for media according to the preamble of claim 1.
  • elastically resilient components can be made of helical springs or helical compression springs in order to achieve the most uniform possible spring characteristic and high elastic resilience even with small dimensions if the spring is always subject to a high preload and / or strong Is exposed to temperature fluctuations. If there are other parts of the device made of plastic, such a spring element is disruptive when it is recycled.
  • springs made of plastic or thermoplastic material with the properties mentioned, in particular very slim spring elements, the largest width or largest diameter of which is less than 20 or 10 mm and / or whose largest spring cross section is less than two or is a millimeter.
  • the invention has for its object to provide a component made of a thermoplastic material or the like.
  • a component made of a thermoplastic material or the like In which disadvantages of known designs or the type described are avoided, which in particular has a high degree of rigidity, such as spring stiffness, and possibly also over the entire spring travel significantly higher temperatures should always have the greatest possible elastic resilience.
  • a metallocene can act as a catalyst in the manufacture of the thermoplastic material. It can be used as a polymerization co-catalyst so that residues of it remain evenly distributed in the material.
  • the metallocene In order for the metallocene to develop the highest possible performance, it is expediently first drawn onto a powdery, insoluble carrier material and fixed thereon. Each powder grain of the carrier material forms a start for the growth of the polymer chains in the subsequent polymerization. Because several active centers on the surface of each grain are identical, all molecular chains grow uniformly over the same length.
  • the catalyst is a transition metal complex with titanium, zirconium or the like as the central atom and cyclopentadienyl analog ligands on the metallocene. Such catalysts can be used to produce an ethylene copolymer with an ⁇ -olefin in which the comonomer is incorporated very uniformly. In addition to titanocene or zirconocene, other catalysts may also be conceivable.
  • the surface structure such as the surface density, but also the elastic resilience are increased. Even after the component has been compressed many times, there is only very little permanent deformation.
  • the discharge device or another device containing the resilient element can only be irradiated after assembly, so that all of its components are exposed to the radiation at the same time.
  • a cobalt 60 source can be used as the radiation source, and an irradiation intensity of at least 85 kGy and at most 120 kGy has proven to be particularly effective.
  • the energy input into the material when irradiating releases electrons from the molecules, creating radicals.
  • a polyethylene with many side chains in the molecule creates relatively stable radicals. These react with each other by combining two reactive polyethylene molecules to form a larger macromolecule, which increases the average molecular weight. This radiation crosslinking is therefore particularly suitable for resilient elements that are permanently pre-stressed or exposed to strong alternating loads.
  • the inventive design also significantly reduces the tendency to stress cracks, so that the component is suitable for always being in contact with the medium despite strong alternating deformations when the medium is being discharged, without the risk that the medium may penetrate or penetrate germs stuck in cracks becomes sterile.
  • the component can also advantageously form sliding surfaces for the operation of the discharge device, for example on a valve body, a displacer or the like.
  • the component can be completely encased and covered on the outside within a housing or a chamber through which the medium flows or is filled with the medium.
  • the component can be arranged in such a way that all of its surfaces, for example the inner and outer circumferential surfaces and the inner and outer end faces, are washed by the medium. Further advantages or improvements of the type mentioned result from the features of the subclaims.
  • the use of a plastic produced in the manner described is proposed for components of discharge devices, in particular for components to be resiliently deformed.
  • the discharge device can be designed in accordance with patent application P 44 41 263.0, which is why reference is made to this patent application in order to include the features and effects in the present application.
  • the discharge device 1 has two units 2, 3 which can be moved manually relative to one another via a working movement, such as a linear stroke, and which thereby form a discharge actuation 4. When actuated, the discharge device is to be held in a single hand and operated with the fingers of the hand in such a way that it is shortened and the medium is thereby placed under a discharge pressure.
  • Each of the units 2, 3 has a separate, one-piece base body 5, 6, which can form the outermost outer surface of the device 1.
  • the elongated base body 5 of the inner unit 2 forms an elongated housing 7, which is to be fastened in a positionally rigid manner with a fastening member 8 on the neck of a store 9 in such a way that it lies within the vessel 9 with most of its length.
  • the components mentioned lie in a central or main axis 10 of the device 1.
  • the unit 3 contains an elongated displacement or piston unit 11 and one outside the base body 5, 6 horizontal discharge or actuation head 12, which forms the base body 6.
  • This base body 6 can be formed in one piece with the unit 11 or be formed by a component separate therefrom.
  • An elongated pressure or pump chamber 13 is provided in the housing 7, which is delimited on its outer circumference and on its inner end by the housing 7 and on the outer end by the unit 11. Outside the inner end of the housing 7, an inlet 14 is provided for the pressure chamber 13, which can be formed by a filling or suction pipe which guides the medium from the bottom region of the reservoir 9 into the housing 7 and the pressure chamber 13 by suction.
  • the housing 7 From the inner end of the housing 7 protrudes into this a projection or socket 16, in which the medium flows from the outer end of the flexible hose 15.

  • the connection between the inlet 14, 17 and the pressure chamber 13 can be valve-free or can be provided with a valve which closes when the pressure builds up in the chamber 13 and opens at a negative pressure in the chamber 13 for the suction of a further media filling.
  • the unit 6, 11 is penetrated by an outlet channel 18 adjoining the chamber 13, via which the medium is supplied under excess pressure to the media outlet 19 provided on the head 12. At the outlet 19, the medium separates from the device 1 into the open.
  • a closure 20, namely an outlet valve, is provided between the chamber 13 and the channel 18, the actuation 4 also forming a closure actuation for the repeated opening and closing of the closure 20.
  • the closure 20 contains only two one-piece closure parts 21, 22, with which a closure channel 23 directly adjoining the channel 8 in a position in the The area of the closing surfaces 24 can be closed in a pressure-tight manner and opened in the other position so that the medium between the closing surfaces 24 flows out of the chamber 13 into the channels 23, 28.
  • the direction of flow 25 of the closure 20 is from the inside to the outside, namely directed as the medium flows through the inlet 14 into the housing 7, out of the chamber 13 and along the channel 18.
  • the actuating movement of the unit 3 is directed in the opposite direction.
  • the closure part 21, which lies completely within the unit 11, is loaded with a spring 26 for the closed position, which spring is mounted or held completely on the unit 11.
  • the unit 11 forms with its inner end a cup-shaped piston 27 with a cylindrical tubular piston jacket 28, the inner end of which is designed as a sealing lip 29 and seals the chamber 13 continuously over its circumference.
  • the piston 27, as the piston crown 31, has an end wall which lies exclusively within the piston jacket 28, forms the outer closure part 22 and is penetrated by the channel 23 in the center.
  • the inner closure part 21 is secured with a sleeve-shaped and rigid support body 32 with respect to the piston 27 in such a way that it can execute axial relative movements with respect to the piston 27.
  • the support body 32 engages in a fixed position at a distance from the closure part 21 into the inner circumference of the piston jacket 28 such that it projects into the chamber 13 via the sealing lip 29.
  • the support body 32 is connected exclusively to the closure part 21 by the spring 26, whereby these components can form a preassembled or one-piece structural unit.
  • a control piston 33 is provided which Expediently formed by the closure part 21 and formed in one piece with it.
  • Delay means 30 are provided for the closure 20, which cause the closure 20 to remain open longer after opening with the closure actuation 4 than would be the case if it were controlled solely by the pressure in the chamber 13 acting on the control piston 33.
  • This pressure usually drops at the latest at the beginning of the return stroke of the unit 11 below the opening pressure of the closure 20, so that the spring 26 would then immediately return the closure 20 to its closed position.
  • This is prevented by the device 20 for a short time so that the closure 20 closes only after part of the return stroke or at the end thereof, the volume of the chamber 13 being reduced with the working stroke and increased from the beginning of the return stroke.
  • the unit 2 has a closure holder 34, which holds the closure part 21 in the open position relative to the base body 5 even when the unit 3 executes relative movements or the return stroke and thereby the closure part 22 moves away from the closure part 21 to the outside.
  • the holder 34 has a holding member 35 on the housing 7 and lying entirely within it, which can be formed by the freely projecting and slightly narrowed end of the connecting piece 16.
  • the pin-shaped or tubular holding member 35 can be closed over the circumference and open at the free end. It lies contact-free inside the chamber 13, to which it does not need to adjoin, but against which it can carry out slight radial movements in all directions due to the bending elasticity of the connector 16.
  • a counter member 36 is used to hold the closure part 21 or control piston 33 in the stated position Provided, which can be formed in one piece with the parts 21, 33 and in the starting position according to FIG. 1 with a free spacing and coaxially protrudes against the holding member 35 away from the closing surface 24 in the opposite direction 25.
  • the links 35, 36 have complementary engagement or friction surfaces 37, 38 which engage with a predetermined friction at the end of the actuation stroke of the actuation 4 when the closure part 21 is open and the spring 26 is under maximum tension.
  • the friction surface 37 of the holding member 35 is formed by an inner circumference and the friction surface 38 by an outer circumference.
  • the friction surface 38 approaches the friction surface 37 from its spaced position until it slides into the holding member 35 via insertion bevels and the friction increases in the further course of this coupling and plug-in movement.
  • the counter-member 36 is fixed in a centered manner by stationary friction with respect to the holding member 35 and the body 5, 7 with the closure 20 still closed.
  • the pressure build-up during the working stroke is usually not sufficient to open the closure part 21 or to open it completely so that this air can escape sufficiently through the closure 20 into the channel 18.
  • the closure part 21 is initially held by the friction surfaces 37, 38 relative to the unit 5, 7, so that the closure part 22 moves away from the closure part 21.
  • the spring 26 loads the closure part 21 in the direction of the closure part 22 or the closed position to an extent which overcomes the static friction.
  • the counter member 36 slides with a decrease in the frictional force along the friction surface 37 until it comes free from it then the closure part 21 is accelerated under the force of the spring 26 and transferred smoothly into the closed position.
  • the closing surfaces 24 then abut one another rigidly, the closing surfaces being able to be formed by complementary conical surfaces and in particular the closing surface of the closure part 21 being an outer cone.
  • the trapped air has sufficient time to expand and thereby escape into the channel 18, which is also promoted by the fact that non-gaseous medium is sucked into the chamber 13 via the inlet 14, 17.
  • This medium can flow out of the end of the holding member 35 against the inside of the piston 33 facing away from the control surface. Since the friction surfaces 37, 38 are still dry when the device 1 is not in use, the friction is initially higher. However, the clamp fit between the friction surfaces 37, 38 is then wetted with the non-gaseous medium by the means mentioned, so that lubrication results in the sense of a reduction in the frictional force by the medium, which facilitates the release by the closure holder 34.
  • friction surfaces 37, 38 can be designed so that they wear out relatively quickly after a few working strokes at least to such an extent that after the venting of the pressure chamber 13, the holding force is reduced to such an extent that the closure 20 at the end of the working stroke or the beginning of the return stroke closes.
  • the pressure-dependent opening path of the closure 20 is substantially smaller than the opening path resulting from the device 30, so that when the opening pressure in the chamber 13 is reached, the closure 20 opens in the manner described before the closure holder 34 comes into engagement.
  • links for centered sliding guidance of the closure part 21, the spring 26 or the piston 33 can be provided, for example guide webs on the inner circumference of the casing 28, a centering projection which only projects into the channel 23 in the closed position

  • a transverse channel leads from the channel 23 into the groove 18, so that the outlet channel from this transverse channel to the entrance of the guide device 54 is delimited by the outer circumference of the unit 52, 65 and by the inner circumference of the head 6, 12.
  • this head In the extension of the nasal prong and at a distance within its outermost casing, this head has an inner sleeve which projects freely in the opposite direction 25 and extends approximately to the bottom 31 and which receives the shaft 65.
  • the depression 58 of the guide device 54 is provided exclusively in the outermost end surface of the shaft 52, 65, so that the channels 63 connect the outer circumference of this shaft to the guide chamber 62.
  • the outer nozzle body is formed here by the end and end walls of the head and nose piece, relative to which the handle 66 is set back in the opposite direction 25 and lies on both sides of the axis 10.
  • a single channel 63 connects the end edge of the body 52 to the chamber 62, and the straight channel 63 to the chamber 62 may be narrowed in width and / or depth.
  • two channels 63 are provided for the chamber 62 which are connected separately to the ring channel 59 and which are located on both sides of the chamber 62 and are each angular.
  • the medium flows from the channel 59 in the opposite direction 25 and in the immediately adjacent angle leg in the circumferential direction to the chamber 62, these angle legs of the two channels 63 opening in opposite directions, but with the same directional swirl effect, opening into the chamber 62.
  • Each of the described components of the discharge device 1 can be made of plastic, in particular by injection molding, which is advantageously provided in addition to the polymer with an addition not made of plastic, in particular a metal-containing or catalytically active addition, namely metallocenes.
  • the catalyst which is only distributed in traces, serves to start or accelerate the polymerization, as a result of which all the molecular chains that are formed become approximately of the same length and a very narrow molar mass distribution results.
  • the cocatalyst, the transition metal complex contained in it or the metal itself can be present in a proportion by weight of less than 1/10000000 or 5/10000000 be contained in the plastic so that the catalyst can remain in the finished component. After the catalyst effect has expired, the catalyst could also be separated from the plastic.
  • the metallic portion of the metallocene can only be titanium or zircon or a mixture thereof if it is a titanocene or zirconocene. This results in particularly good crosslinking during the transition from the monomeric to the polymeric molecular structure or in the chain formation of the molecules.
  • a further improvement can be achieved in that the plastic as a molecular structure instead of a pure polymer is a co-polymer, e.g.
  • the proportion by weight of the ⁇ -olefin expediently being at least 3% and at most 40%, in particular at least 5% and at most 30%.
  • the ⁇ -olefin suitably has two to six carbon atoms.
  • the plastic is very resistant to solvents and chemicals and has high softening temperatures, while containing little extractable components. Furthermore, the plastic is odorless and tasteless. It has a high shock resistance, a good or dense surface quality, a low thermal distortion and a very good stress crack resistance.
  • These properties can be further increased by irradiation of the finished molded component, in particular by gamma radiation.
  • the radiation intensity expediently being at least 85 kGy and at most 120 kGy, in particular about 100 kGy.
  • the crosslinking of the molecular chains or the gel fraction of the plastic can also be significantly increased.
  • the properties mentioned are significantly improved, in particular in comparison with plastics which have been produced using conventional catalyst systems, for example using what are known as Ziegler-Natta or Phillips catalysts.
  • the radiation by an electron beam accelerator or the like can be exposed to the respective component by itself or only after assembly with at least one further component or after ready-to-use assembly of all components of the discharge device 1, so that the radiation can be carried out very easily and has a sterilizing effect.
  • All components of the device 1 are made of plastic, so that they can be fed together for material recycling.
  • the springs 26, 39, 49, the sealing members 29, 46 or the associated structural units 11, 40 while the other components are made of plastic can be made without admixture.
  • the respective spring is designed in the manner of a spiral spring, the windings of which are not only connected to one another along the helical pitch, but are also connected integrally to one another transversely thereto via connecting sections which have a steeper pitch compared to the helical pitch or the axial connections between adjacent ones along the circumference of the spring Form spiral sections.
  • the spring can be designed in the manner of a bellows.
  • the support bodies 32, 41, the valve body 21 or 22, the control piston 33, the counter member 36 and the shaft 65 including the outlet body 52 can consist of the finished plastic.
