Definitions
- Discharge device for media
- the invention relates to a discharge device for a single medium or a plurality of media, which can be gaseous, liquid, pasty, powdered or powdered or the like. And / or a mixture of such customary media to be discharged, and a method for their production and for filling .
- a replacement medium which is not or not primarily intended for discharge.
- This can be, for example, a medium which does not chemically react with the customary medium and / or does not dissolve physically in the customary medium, so that the two media are clearly separated from one another, at least in the low-flow, calm state, despite their direct abutment.
- the replacement medium may contain impurities such as dirt, germs or other components which react with the custom medium, which then spoils the custom medium for its predetermined medical, cosmetic or other purposes.
- preservatives, stabilizers or similar substances can be added to the service or replacement medium, but these are often undesirable because of medical side effects, for reasons of cost or the like.
- the invention has for its object to provide a discharge device and a method of the type mentioned, in which disadvantages of known designs or the type mentioned are avoided and in which undesired contamination of the customary medium, in particular, substantially reduced to avoided can be provided as long as this medium is not discharged but is still stored externally.
- a single or at least one compensating and / or a receiving container for receiving a single replacement medium or a plurality of different replacement media, the receiving space of which can be essentially closed at least in one operating state with respect to one or the associated container space. Is the receptacle only partially or not with the
- the service medium In contact with the service medium, it can be filled, for example, with a replacement medium free of the contaminants, or hermetically sealed against the ingress of contaminants to the outside, and the replacement medium, depending on requirements, to the areas of the service medium free from the service medium deliver the container space via one or more pipe connections. It is particularly expedient, however, if a receptacle with a container wall or the like is directly adjacent to the service medium or partially or largely or almost completely fills the space areas of the container space that are free of the service medium, essentially independently of this with which variable degree of filling or to which Percentage the custom medium just fills the container space. In contrast to a trailing or climbing piston or the like, no large-area and tight sliding seats are required, which in turn can hardly be sealed against the ingress of impurities.
- the volume of space occupied by the customary medium can be approximately limited to the volume of the filling with the customary medium, regardless of the total volume of the container space, so that there is always an at least approximately full filling of this area only with the custom Medium results.
- this custom filling can essentially only adjoin the position-changing container wall of the receptacle, so that the design according to the invention is only suitable for this purpose instead of the effects mentioned to protect the custom filling against shaking movements.
- the receptacle adjacent to the custom filling can also be provided for influencing the pressure of the custom filling or in the container space by changing the position of a container wall or the like, for example in order to create a vacuum or for suction Discharge of the custom medium to generate an overpressure or to cause its damping in the case of pressure changes caused differently.
- a container wall of a receptacle in at least one operating state, can be biased and / or lifted against the inside of a vessel wall and, if necessary, thereby elastically support it.
- a receptacle can also be provided alone for substantially completely displacing the stored service medium from the container space and / or the external shape of a container Obtain vessel essentially independent of the degree of emptying, because, for example, the receptacle, after bulging, may reset the walls of the vessel via the medium lying between it and the wall.
- a receptacle for a medium separate from the customary medium is almost suitable for any discharge devices or vessels, e.g. for bottles, tubes, pumping or cylinder rooms of thrust piston pumps or the like, bag bundles, canisters, tanks, etc. If the service medium is volatile or easily flammable, can be used with a receptacle or Substitute medium dangerous gas mixtures are essentially completely expelled from the container space.
- a receptacle for the named or other purposes is expediently not designed as a bellows, the wall of which forms pre-folded articulated zones over the largest areas of its extension, but the wall can assume any desired folds and is advantageously so flexible that the receptacle forms a sagging bladder in the emptied state, the opposite wall areas of which can be placed against one another with their inner sides without any particular effort.
- the receptacle can thereby be reduced to a room volume that is significantly less than half, a quarter or a tenth to at least a fiftieth of its room volume in the maximally filled operating state.
- a valve For filling or emptying a receptacle and / or a container space, a valve can be provided which is controlled as a function of flow or pressure instead of by mechanical actuation, in particular in such a way that it essentially can only be flowed through in one direction, while in the other direction its flow cross-section is narrowed or completely closed in the case of currents in the other direction.
- the discharge device provided in the area of an outlet, which can also be formed by a pump unit separate from the vessel or a thrust piston pump, a bellows pump or the like, and through which the service medium flows when it is discharged, can control the passage of the receptacle influence or effect.
- the passage of the receptacle can be closed or opened essentially before, during and / or after the outflow of the custom medium.
- the control is provided in such a way that the replacement medium or the receiving container is exposed to an attractive effect essentially only due to a vacuum created by the discharge of a batch of the custom medium in the container space, which leads to its spreading into those areas of the container space which have become free through the discharge of the custom medium.
- the respective receptacle can by a
- Area of an emptying opening provided or formed by this emptying opening partially or completely inserted into the container space and this opening may also be used as a mounting opening for positionally anchoring the receptacle within the container space.
- a mounting opening further away or separate from this is expediently used, which e.g. penetrates a wall opposite the discharge zone of the container space or a bottom wall of the vessel.
- Anchoring an associated section of the receptacle can advantageously be considerably more rigid due to profiling or the like than in particular to be connected transversely thereto.
- This or another assembly wall can also be reinforced by a type of cross-sectional thickening, which e.g. is formed by a separate body, such as a holder, a flange, a closure for the assembly opening, a valve housing or the like.
- a type of cross-sectional thickening which e.g. is formed by a separate body, such as a holder, a flange, a closure for the assembly opening, a valve housing or the like.
- the vessel space can also be filled with the service medium through an assembly opening, after which the associated receptacle can then only be inserted and assembled and the assembly opening can thereby be closed.
- the receptacle including the closure, can form a preassembled structural unit, which is expediently to be inserted into the mounting opening in a manner that is limited in terms of the stops so that its sections which may be on the outside of the vessel or the discharge device are completely recessed in a recess on this outside.
- the expansion tank or the like can also consist of the same or a material with the same properties as the other limitations of the tank space, for example in order not to bring the service medium into contact with different materials or to ensure that the material is reused To facilitate container materials without cumbersome previous sorting.
- the inside of the outer container can be provided partially or completely or in all areas coming into contact with the medium with a film-thin or similar lining or coating made of the corresponding material, which expediently integrally with the volume-adjustable compensation - Or filler is formed.
- This filler body can advantageously be turned inside out by an opening formed in one piece with it and / or delimited by the outer container by turning the inside to the outside, as a result of which it moves from an outer position into an inner position in the outer container - 7 -
- the opening can be narrower or approximately the same width as the largest or middle width of the respective container, depending on how flexible the walls of the slip-on container are.
- the filling body can be inserted or introduced into the outer container mechanically or additionally or exclusively by at least one driving fluid which also has a negative pressure constricting or sucking in the filling body in the outer container and / or an overpressure which promotes the filling body in the outer container causes.
- the lining or the substantially maximally expanded filler lies on the inside of the outer container essentially without any wrinkles over the entire circumference as well as on the end faces and, if appropriate, in the area of the container openings or nozzles, so that the container space is completely emptied without remaining any cavity is possible.
- the outer container is designed as a mold for the lining or the filler. If the container body or the filler body is produced from a blank, for example a hollow, cup, sleeve or hose, while reducing the wall thickness by stretching, the lining or the filler body can be brought into its finished form after the outer container has been completed or then are, while also the outer container is subjected to the mentioned shaping.
- the respective outer, lining or filling container if appropriate at a suitable elevated temperature, can be subjected to a fluid pressure inside and / or exposed to a vacuum on the outer circumference and thereby shaped against a tool which is only a negative shape of the outer shape forms. It is therefore possible to produce by the extrusion or blowing process. Irrespective of the designs described, two containers which adjoin one another and, if appropriate, delimit separate spaces can also be produced approximately in one work step together and / or at least partially to substantially or completely in one piece. At least parts of the wall of the two containers can have very different wall thicknesses corresponding to 5, 10 or 15 times, these values being able to represent minimum or maximum limits.
- the walls of one container can be inherently rigid and those of the other can be of considerably lower strength, so that it can be bent or folded like a film.
- the two containers can be prefabricated in a mutual outer layer, after which the less rigid container is expediently at least partially transferred into the more rigid container.
- the designs according to the invention are also suitable for so-called squeeze bottles, from which medium is discharged by manually squeezing the squeeze container and thereby in it. located medium is subjected to an excess or discharge pressure.
- medium can be discharged from two containers holding one another, using the same manual discharge actuating pressure simultaneously, successively or overlapping in time, from both containers and separate outlet openings, a common outlet opening and / or or can be fed to an application point outside the respective discharge opening if the discharge device is in a constant position.
- the inner container can be exposed to an excess pressure via the fluid contained therein, through which the medium contained in it is discharged.
- the compensation space of the inner container is then refilled by a volume equal to that from it - 9 -
- volume discharged corresponds to the volume which has been discharged from the outer or media container. If, as is also conceivable, no medium is to be drawn into the expansion tank from the outlet opening of the discharge device or the media tank, a suction opening separate from the outlet opening of the expansion tank can be provided, which e.g. associated with the atmosphere.
- a corresponding valve control can be provided, optionally with valves opening and closing alternately or offset, which operate in a pressure-dependent and / or path-dependent or mechanically controlled manner.
- the invention also relates to a method for producing a discharge device, which can be configured as described or differently.
- a discharge device which can be configured as described or differently.
- at least two containers which may have substantially different or approximately the same, in particular not inherently rigid, wall thicknesses, are produced or shaped in a mutual material connection, after which they are transferred from this shape position into a different operational or initial functional position the.
- This enables very simple production, e.g. a one-piece production, a production in heat and / or a production in a single operation, unless the shaping of the two containers is provided completely or at least partially in such a time sequence that after the one container has been finished molded the other is subjected to further shaping.
- the invention relates to a method for filling a discharge device of the type described or another type, in particular for filling with one of the media mentioned or fluids.
- the container space to be filled is expediently narrowed to a substantially to completely void-free volume and then filled with the medium in such a way that it is only expanded by the volume of the medium introduced in each case until it has taken up its predetermined filling quantity.
- the ingress of foreign medium or air into the filling space can be completely ruled out and the discharge device can be filled without bubbles in the filled initial state.
- the filling can take place under overpressure, which works against the internal pressure of the expansion tank and leads to its simultaneous emptying or reduction, and / or the expansion tank can be placed under a vacuum by evacuation , which leads to the medium being sucked into the container space.
- the respective container e.g. the expansion tank is so narrowed during emptying by means of a random folding with wrinkling or the like of its walls that opposite walls are placed against one another with their insides essentially without gaps or the
- Container is even substantially to completely free of voids and only occupies a volume that corresponds to the simple or at most 4 to 5 times the material volume of its walls.
- the inner container on the outside expediently has at least one or spaced apart projections, such as folds, ribs or similar spacers, which take place the latter, or in addition, can also be provided on the inside of the outer container and through which passage gaps for the medium remain free even when the inner container lies against the inside of the outer container Has. In this way it can also be avoided that the inner container divides the outer container into two tightly separated container spaces.

- FIG. 2 shows the discharge device according to FIG. 1 in a partial enlargement
- FIG. 8 shows a further embodiment in a representation corresponding to FIG. 5,
- FIG. 11 shows two further embodiments in representations and 12 lungs corresponding to FIG. 1.
- the discharge device 1 has an elongated bottle-shaped vessel 2 in the form of a thin-walled hollow vessel body made of flexible plastic, which delimits a container space 3 of appropriate shape and can be almost completely gripped with one hand.
- the vessel body 2 is essentially formed by vessel walls 4 to 6 of approximately constant thickness throughout, the thickness of which is less than 5 or 2 mm and can be of the order of 1 mm.
- An approximately cylindrical vessel jacket 4 integrally connects at one end to a bottom wall 5, which may be in the form of an annular disk, and at the other end in the region of a discharge zone 7 to an end wall 6, through which the service medium flows through a vessel Neck 8 is to be discharged out of the vessel 2 to the outside, the bottom wall 5 and / or the end wall 6 being essentially stable in shape in contrast to the vessel jacket 4.
- a discharge device 9 On or in the neck 8, which in one piece only protrudes from the end wall 6 and is also dimensionally stable, is a discharge device 9 with a The basic body is used essentially in a fixed position and centered, through which the customary medium is to be discharged.
- At least one filling leveling device 10 is provided for such or another discharge device 1 in order to partially or completely fill the space area 13 of the container space 3 free of the customary medium 11 in such a way that the space area 13 is flush with the surface of the medium directly 11 occupied space area 12 adjoins.
- the two spatial areas 12, 13 are complementarily deformable, e.g. so that when the position of the vessel 2 changes, the specifically lighter space 13 always has a tendency to rise upwards relative to the space 12.
- the room area 13 is therefore stretched towards the discharge zone 7 by buoyancy, while it rises towards the bottom wall 5 when the head is upside down.
- the area 13 is essentially completely occupied by a compensating or supplementary medium 14, which is sealed off from the area 12 and enclosed in a receptacle 15, which here is essentially completely encapsulated within the container space 3 and how its
- the container wall 16 is essentially freely movable in relation to this container space 3 or the space area 12 over most of its extent in the direction of one, two or three spatial axes.
- the continuously one-piece and approximately constant thick container wall 16 is essentially limp, but is self-resilient and / or permanently deformable by tensile strain without tearing. It can be folded equally at any point without any damage and therefore the receptacle 15 can also be crumpled so that the recording space enclosed by it is reduced to a zero volume.
- the receptacle 15 By filling with the medium 14, the receptacle 15 can be continuously converted into all intermediate sizes up to its maximum volume size with unfolding, sections of the receptacle 15 or the container wall 16 adjoining each other in the longitudinal and / or transverse direction being substantially independent of one another in these directions and / or are deformed or moved transversely to their surface and can therefore adapt to any distribution of the medium 11 in the container space 3 or space area 12.
- the receptacle 15 can fill the container space 3 almost completely or at least 80 to 90%.
- the receptacle 15 is fixed with respect to the container space 3 with a holder 18 only at a single point 19 located close to the boundary of the space 3, while all other areas of the receptacle 15 up to the flat abutment on the vessel walls 4 to 6 are freely movable relative to the container space 3 in each of the directions mentioned.
- the receptacle 15 forms with the bracket 18 or one or two bracket bodies 21, 22 a pre-assembled unit 20 separately from the vessel 2, which can be mounted on the vessel 2 even with the discharge zone 7 tightly closed so that the bracket bodies 21, 22 are in their predetermined Functional position are connected to the receptacle 15.
- This structural unit 20, which could possibly also be inserted through the neck 8, is then inserted from the outside of an associated vessel wall 5 with most of its extent into the container space 3 and is fixed with respect to this vessel wall 5 by the holder 18.
- a holder body 21 lies essentially over the entire surface on the inside or on the inner circumference of the container neck 17, and the other holder body 22 lies on the outside or on the outer circumference of approximately the same longitudinal section of the container neck 17.
- the clamping surfaces of the clamping seat 23 are self-locking, acute-angled to conical with approximately the same cone angle and narrowed towards the outer end of the container neck 17, so that the inner holder body 21, which forms its holder surface on the outer circumference, extends from the inside of the receiving container 15 into the outer Bracket body 22 is to be used.
- the clamping gap of the clamping seat 23, which extends to the outside of the vessel 2, can only be sealed by the container neck 17 lying in it and / or thereby both against the customary medium 11 and against the compensating medium 14, that between the container neck 17 and the
- a respective direct sealing or adhesive connection is provided for each clamping or mounting surface, which can be a fusion connection, an adhesive connection or the like.
- a seal 24, for example an annular seal, can also be provided to seal a mounting gap.
- the holding tion body 21 are pre-assembled with the receptacle 15 so that the container neck 17 is fixed in its longitudinal direction with respect to the holder body 21.
- a holding and / or tensioning member is provided, which tensions the container neck 17 against the outer circumference of the holder body 21 and / or secures it by cross-sectional deformation.
- the holding member can be formed by the seal 24 and engages in a circumferential groove in the holding surface of the holding member 21 with radial prestressing such that it stretches the container neck 17 in this area over the entire surface against the bottom surface of the circumferential groove or depression.
- the container neck 17 together with the holder body 21 and the holding member 24 can be inserted axially into the holder body 22 up to the stop, a snap connection engaging at the end of the plug-in movement, the snap member of which can also be formed by the seal 24.
- the mounting surface of the mounting body 22 also has a recess or circumferential groove or a similar snap counterpart, which is adapted to the snap member 24 and into which the seal 24 projecting outward beyond the mounting surface of the mounting body 21 snaps in under a prestressed manner.
- the receptacle 15 is highly flexible in connection with the container neck 17, its container wall 16 for mounting the holder body 21 can be placed on its rear end face in the plugging direction and, with the help of the container wall 16, the holder body 21 can be pressed into its mounting position.
- the end face of the holder body 21 expediently protrudes slightly beyond the associated end face of the holder body 22, the clamp seat 23 expediently extending approximately to the latter end face.
- the support body 22 which is essentially dimensionally stable like the support body 21, forms with its end facing the container space 3 a centering section 25 which projects freely into the space area 12, which at the outer end integrally merges into a ring flange-shaped support flange 26 which projects beyond its outer circumference and closely to the vessel wall 5 penetrating mounting opening 27 is adapted.
- This assembly opening 27 is narrower than the inner width of the container space 3 or the vessel wall 4 following the vessel wall 5, so that the container neck 17 and the centering section 25 have a radial distance from the inside of the vessel wall 4.
- the centering section 25 With a small axial distance from the inner, annular end face or support surface of the support flange 26, the centering section 25 carries in an annular groove an annular seal 28 which, like the seal 24, is made of elastically resilient material and can be elastically deformed in cross section by squeezing.
- the spatial area 12 in the area of the assembly opening 27 is sealed to the outside with this seal 28.
- the seal 28 and / or another member can also form a snap member of a snap connection 29, with which the holder body 22 is secured in a form-fitting manner with respect to the vessel wall 5 essentially without axial play by axial bracing and frictionally secured against rotation.
- the seal 28 When the holder body 22 preassembled with the seal 28 is inserted into the mounting opening 27, the seal 28 is initially radially narrowed by sliding along the inner circumference of the mounting opening 27 and then overlaps both the inside of the vessel wall 5 and the inner circumference of the mounting opening 27 so that the support surface of the support flange 26 bears against the outer surface of the vessel wall 5 under the prestressing of the seal 28.
- the receptacle 15 then extends freely from the inner end or end surface of the holding body 21 or 22 into the container space 3.
- the receptacle 15 possibly also as an untied, free-floating bubble in the container space 3, to be completely hermetically sealed and, for example, to fill it with a medium, such as a reagent, which adapts itself, before it can be opened only by destruction the emptying of the room area 12 expands.
