Description

MEDIUM DISPENSER DESCRIPTION OF THE INVENTION The present invention relates to a spout as a discharge unit for means in the form of powder and / or liquids in the form of a gaseous or thick gel, especially pressurized, which in the region of an outlet from the medium, they preferably leave the spout finely pulverized and thus remain free. The means can be provided for a technical, cosmetic or medication application for example for the treatment of the nose, eyes, skin breath or the like. The media that is used is often easily decomposable especially by contamination with bacteria, spores or the like or by contact with atmospheric air so that in the interest of being able to keep them in storage as long as possible, preservative substances must be added to the distribution unit already full The invention proposes the task of creating a dispenser for certain media in which the disadvantages of the known constructions or the described technique disappear and in which a contact of the medium in rest state found in the unloading unit with the atmospheric air, guaranteeing also a simple assembly. According to the invention, a closing or valve unit is placed in an outlet support in the current direction. The shaping in accordance with the present invention is suitable for a flattened bottle wherein the feeding chamber for the medium is compressed by grasping it by hand in a volumetric manner. Means are provided by which the feeding chamber independently of the filling state is always full, for example in such a way that the volume of the feeding chamber decreases in size proportional to the emptying that occurs. An exit support can be fixed on one or two axial planes that are perpendicular to each other in a direction opposite to a front wall so that these pressure surfaces by the action of the fingers on both sides, serve for the axial operation and the shortening of the download device or distributor. The spout may have one or more drive pumps, such as plunger balls. In its pumping space or narrow pressure can suck half during its return stroke the pump that is simultaneously operated manually from the pressure space can drive a dispersion gas and the other pumping space simultaneously bring the non-gaseous medium to for example, spraying a highly viscous medium. The two closures can open or close with respect to each other with a delay in time. The pressure or pumping space can also contain the entire volume of stored medium of the distributor device and be provided instead of the above with an inlet valve opposite the plunger having the floor of the pressure chamber as a permanent closure.

These and other features are set apart from the claims also from the description and the drawings where each of the individual or several characteristics may be presented in the form of sub-combinations in one embodiment of the invention as well as being carried out in other fields of application, all of which is claimed here as the protection that is requested. Examples of embodiments of the invention are shown in the drawings and will be explained in more detail below. In the drawing shows: Figure 1 a spout partially in section; FIG. 2 shows a mounting unit of the dispenser according to FIG. 1 in an alternative embodiment; Figure 3 another embodiment in one corresponding to Figure 2; 4 shows a section of FIG. 1, but in an alternative embodiment; Figure 5 shows another embodiment of a dispenser in a representation corresponding to figure 1; Figure 6 shows a section of figure 5 in a sectional view and substantially enlarged; 7 shows another embodiment partially in partial section. The dispenser 1 presents, according to FIG. 1 or FIG. 5, a rigid or elastic base body 2 that serves as the outermost box, it is composed of a container 3 and a cover 4 essentially shorter but having an axial view the same external shape, between the box parts 3, 4 is disposed a fully encapsulated carrier unit 5, which is axially tensioned with respect to the box part 3 or 4 and fixedly fixed radially being like that of rigid form . If a fixed plunger shape is provided with its pumping box with respect to the box part 3, it would be the case part 4, possibly axially displaceable with the unit 5 with respect to the box part 3 to drive the pump and then carry the plunger of the pump. On the outer side of the cover 4 an axial support 6 suitable for insertion into a nose opening, on its end surface of the outlet 7 for the medium or a single outlet opening 8 having a diameter of less than 1 mm or less, protrudes. 5mm. At less than a distance of 2. 1, or 0. 5mm from the opening 8 is active a closure or valve 10 that closes hermetically, at pressure, inside the box 2, in the resting state of the unit 1, against the outside atmosphere and only opens during the medium distribution. The arrangements 6, 8 and 10 are on an axis 9 which is offset laterally with respect to the central axis of the box 2. Inside the box 2 there are provided two first and second feeding chambers 11 and 12, in the state of rest, sealed between them and closed with respect to the external atmosphere. The feed chamber 12 is completely inside the chamber 11. The box 2, 3 presents from an enclosed floor 14 to an interrupted cover wall 15 an external jacket 13, which in an axial view is deformable by stretching longitudinally or on one surface oval and elastically. The volume of the chamber 11 or 12 decreases due to the radial compression of the jacket 13. From the front wall 15, two neighboring supports 16 and 17 project parallel to the axis proper for a special filling or emptying of the chambers 11, 12. support 16 a control unit 18 has been provided. In the support 17 a hollow neck 19 of the chamber 12 is arranged. The units 18, 19 limit as the free end surface of the support 16 together with the inner side of a plate 20 of the unit 5, with which an end link of the neck 19 is sealed with tension against the support 17. From the plate 20 two safety members 21, 22 project inwardly in the form of a sleeve one of them grasps radially between the support 16 and the unit 18. The other one grabs in a widened section of the inner periphery of the neck 19 and radially tensioned against the support 17 the projection 6 has an outer jacket 16 which is attached in one part to the box 2, 4 and has a length of at least twice as much as its external width of size. At the free end the sleeve 23 changes, being a piece, to a front wall 24 in the form of an annular disc. It limits the nozzle channel 8 that passes through it. This channel can at the inner end form a closing seat or conically widened valve of the valve 10, inside the support box 23 that opens towards the container 3 there is a fixed central sleeve 25 and in this other displaceable core 26 rod. axially. Directly adjacent to the front wall 24 the sleeve 25 has an annular disc-shaped front wall forming a pre-spray nozzle 27 at its free end. From this nozzle only the medium comes out from the chamber 11 under spraying, the nozzle channel travels in its current and when it is released from the edge of the opening 8 and from the spout 1 it is finely pulverized again. An outlet channel 28 having an annular shape in its cross section or which is divided into axial channels is limited by the outer periphery of the rod 26 and the sleeve 25., channel 28 joining the chamber 11 with the openings 8, 27 and closing with the valve 10. By the sleeve 25 and the internal surface of the box 23, 24 another second outlet channel 29 surrounding the channel 28 is limited. , which joins the chamber 12 with the nozzles 8, 27 and opens into the opening 27 and the inner end of the nozzle channel 8 directed against the axis 9 between the front surfaces of the front walls. In this mixing zone, the medium leaving the nozzle 7 is mixed as a half-second in the form of gas or air for a finer spray. The radial sections of the outlet channel 29 can form a turning device, by means of which the gas is rotated about the axis of the nozzle and thus fed to the nozzles. The sleeve 25 is a constituent part, in one piece, of fixed seat of the carrier 5 or of the plate 20 on which it only projects outwards. Only through the inner side of the body 20 and in the supports 16 is a free protruding special carrier 30 of the plate 20 belonging to the unit 18. At a certain radial distance inside the box 30 is a control box 31, whose sleeve 34 and the floor 35 are constructed in one piece with the shirt 33 and the floor of the box 30, as well as being joined together to form a fixed seat. The walls 33, 35, 34 are formed by a component part dependent on the members 20, 21, 26, which is fixed in the member 21. The sleeve 34 is hermetically sealed permanently at its outer end open and directed towards the opening 8 with a lid that grips with a retaining section 36 fixedly in the sleeve 34. The front wall of the hood-shaped lid forms as valve spring an elastic intermediate section 37, axially movable with which it is attached in one piece the internal end of the rod 26 within the members 26, 21, 33, in the immediate vicinity to the internal side of the plate 20. The constant width crossing the rod 26 is basically less than that of the section 37 which is everywhere fitted outwards, sealing tightly the control space 32 and for the opening of the valve 10 moves axially towards the center of the space 32. Between the boxes 30, 31 there is a connecting channel 38 of the exit channel 28 that starts from the floor 35. This channel 38 leaves the openings - junctions 39, which cross the floor 35 between the liners 33, 34 around the axis 9 of the boxes 30, 31. The channel 38 forms a pressure space that essentially widens with respect to the channel 28 in the cross section of flow passage. If the medium from the chamber 11 is pressed to that pressure space 38, then the section 37 acts as plunger, which with its axis or rod 26 moves towards the floor 35 against its own spring force, and for that same force spring recovers its closed position again. The output channel 28 or 29 that passes through is a capillary channel, in relation to which the flow section of channel 38, 39, is several times greater. In its narrowing, an increase in pressure occurs in the dry space 32, whereby the recoil spring force is also caused and the same is adjusted. The opening movement of the parts 26, 37 is in the opposite direction to the current direction 40 in the channels 28, 29 or to the openings 8, 27. The cover 4 has an external front wall 41 and of this only a sleeve 42 projecting towards the chamber 11, which sleeve grasps a narrow end section of the container 3 approximately to the front wall 15, so in which the supports 16, 17o, 19, 21, 22, the plate 20 and the boxes 30, 31 are completely left. The outer side of the plate 20 is tensioned against the internal side of the wall 41 and forms with it a junction plate 20, 41. The carrier body 5, 20 can be fixedly mounted on the container 3 or on the lid 4 before placing this, then, but before the chamber 12 with the neck 19 has been put through the supports 17. The preassembled unit of the boxes 30, 31 and the rod 26 may be before or after the assembly of the carrier body 20 fixed to the cover 4. Preferably for the purpose pursued first put the camera 12, then the carrier 5 and then the lid 4. The chamber 12 is connected by conduit with the a outer surface through an inlet valve 43, which is supported on the inner side of the wall 41 within the member 22. The wall 41 has an inlet opening 44, which is lockable and openable with a valve body movable depending on the pressure. The valve body 45 in the shape of a hinge forms a part with the carrier body 5, and is hingedly movable to open against spring force. The valve body 45 remains in the plane of the plate 20. The chamber 12 is limited by a blower or a screen 46 of a highly flexible, foldable and icro-thin sheet, which without damage to its material volume can be placed on the neck 19 and in this way easily in the container 3. The neck has a much greater thickness of wall with respect to the sheet and can be constructed in one piece with the screen 46. From the support 22 branches in the vicinity of the valve 43 a channel of junction 47 towards the inlet end of the channel 29. The channel 47 is limited by the parts 20, 41. Also this channel 47 is several times wider in the passage cross section than the channel 29.

The free end of the rod 26 forms a valve body 50 in a conical tip closure member. It remains in the closed position in the valve seat 51 forming the opening 27. If the container 3 without deformation of the cover 4 is compressed and the chamber 11, 12 is pressurized, the valve 43 will be secured in its position of closing. From the chamber 12 the medium flows successively through the arrangement, 19, 22, 47, 29 inwards, from the end of the nozzle channel 8 not closed by the closing member 50, and by the channel 8 along the length of the outer periphery of the closure member 50, outwardly, since the closure member 50 penetrates a part of the length of the channel, in that nozzle channel with its tip. Simultaneously, the medium flows from the chamber 11 through the opening 39 to the pressure space 38 which is still closed by the valve 10. The pressure causes the opening movement of the body 50. The medium can flow from the pressure space 38. through the channel 28 to the opening 27, mix there with the air that is already flowing and then exit through the nozzle 8. In the open position the body 50 with the valve seat 51 forms an annular nozzle or nozzle opening 27. Its maximum width reaches when more than that of opening 8.

As soon as the manual pressure is removed from the container 3, and the pressure in the chambers 11, 12, 38 is reduced, the valve 10 will close, while the medium can still flow from the chamber 11 through the opening 8, being able to clean. As soon as the valve 43 opens depending on the pressure, the air is sucked into the chamber 12. The chamber 11 can always be free of bubble, filled with medium and completely emptied, properly up to the screen 46 of the box 2, 3 The unit 5 is fixed by a snap connection 48 to the part 4. The outer edge of the plate 20 forms a snap-in member, which seizes on a counter-member at the inner periphery of the lid. The cover 4 is fixed in such a way to the container 3 with a corresponding fitting connection that the plate 20 and the neck 19 are tensioned between the end surfaces of the supports 16, 17 and the wall 41. With a snap connection it grasps the member 21 on the inner periphery of the support 16. All the described constructional parts consist of synthetic material and are up to the rigid part 46. The dispenser 1 may consist solely of synthetic material. The arrangements 16, 18, 30, 31 remain on the axis 9. The chamber 11 can be filled through the support 16. According to FIG. 1, the sleeve 36 of the section 37 projects only inwards. According to FIG. 2, it does not protrude over the spherically curved internal side of the section 37. The unit 30 forms, by fitting into the member 21, a constituent part of the unit 5. According to FIG. 3 it grasps the sleeve 36 at the top. to the jacket 34, also at the outer periphery with its sleeve section, which is radially tensioned between the jackets 33, 34. According to FIGS. 2 and 3, it reaches the section 37 outwards as far as the outer front surface of the sleeve. cuff 36. According to FIG. 4 is the cross section of constant passage of the channel 28 substantially greater than that of the channel 29. the sleeve 33 abuts an annular projection in a shoulder of the support 16. The body 50 also closes the inner end of the nozzle channel 8 and the internal ends of the radial section of the channel 29. The empty distance between the support 16, 17 is basically smaller than its individual widths. The space 32 is limited by a foldable shirt or bellows 37 in the form of a bowl, which is inside the jacket 34. Its open end forms the sleeve 36 that can be detachably supported on the floor 35. The other end is transformed forming a piece in a plunger 52 in the form of a circular disk, from which the rod needle 26 starts, and which slides with a sealing lip on the sleeve 34. In this way, another annular space, the boundary between the jackets 27, 34, is limited. which is always hermetically blocked with respect to the middle of the chambers 11, 12.

According to Figures 5 and 6, not only is the core 25, but also the sleeve 33 a constituent part in a unit part 5, 20. The engaging part 33 takes the functions of the member 21 according to the Figure 1. It is fixed by a snap connection in the support 16. Its width is essentially smaller than that of the support 17. Channel 28 is narrowed at an acute angle in the direction of current and over most of the length of the sleeves 33, 25 of approximately the same width is limited only by these or by the carrier body 20. The valve shaft 26 is provided with the installation 18, completely within the support 6, and only penetrates a part of its length. the box 31 is formed by a part of a special piece. This is fixed to the outer end of the rod 25, reduced in width, by the engagement against the direction 40 and contains the sections 36, 36, 52 as well as another valve body 53 for the channel 29. The sleeve 36 is fixed on the reduced section of the rod 25, and closes directly to the bellows 37. Its sealing lip 53 in the form of a sleeve slides hermetically on the sleeve 23, with the lip the rod 26 protrudes in the direction 40. It is surrounded by the member 53 as well as in this of a sleeve protrusion of the front wall 24 directed upstream. An even smaller end section of the rod 25 protrudes freely in the sleeve 37, approximately up to the front wall of the plunger 52. The channel 28 opens into the chamber 32, which surrounds that final projection. The front wall of the plunger 52 is crossed by an intermediate channel 54. Which joins the chamber 32 with the chamber 38, which is limited by the interior of the piston 52, of the aforementioned sleeve protrusion and of the rod 26. The channel 54 is in the form of a groove along the rod 26. If medium flows under pressure through the channel 28 to the chamber 32, then it comes from there through the channel 54 to the chamber 38, for which the control plunger 52 moves against the direction 40 towards the support 6 and the rod 25 moves by tensioning the spring 37. With this it slides to the sealing lip 53 in the area of the depressions or grooves 27 adjacent to the internal periphery of the sleeve 23, so that the duct junction between channel 29 and chamber 38 is opened. The gas flows through the openings 27 in the chamber 38 and draws the medium into the open body 50, so that it emerges as a mixed medium-air stream. The opening of the valve 10 can take place a little before the opening of the valves 27, 53. The member 50 always protrudes in the direction 40 more than the member 53. After it is free of the manual actuation force they return simultaneously the members 50, 53 to their closed position thanks to the force of the spring 37. The head 6 and / or the inlet 44 can be covered with a protective body or cap in the form of hood 55 removable. This has a cover sleeve 56 fitted exactly to the support 6, which closes the opening 8. In the region of its free end it is fitted through an elastic connection in the support 6 in an axial manner, being secured there. Especially of the closure body 56 and at a certain distance thereof protrudes from the inner side of the same cover wall, another closure body 57 for the inlet 44, which grips in this opening 44. The needle 57 may keep the valve slightly open. 43 for the pressure equalization of the chambers 11, 12. According to FIG. 7, the core part 25 controls the flow of medium towards the opening 8. The sleeve 25 consists of a soft elastic material compared to the rest of the material. Under a medium pressure, guide with the seat 51 against the base body 2, 4 or the member 50 in the direction 40, an opening movement of the closure 10. This can only take place by a longitudinal stretch of the spring return core 25, or when the core 25 is loaded by a movable spring. A carrier 58 of the core 25 has a circular disk shape that is in plane or at a right angle transversely to the axis 9, forming a part with the core 25 as it will be formed in one piece by the unit 5 or the carrier 20. This takes on a collapse to the carrier 58 of the corresponding unit 60, which ensures a snap connection or bayonet. the carrier 58 is formed as a spring spring in the direction of the axis 9. The outer end 27 of the core 25 is also constructed on the outer periphery as a truncated cone. This conical end section is supported with a certain distance in an inner cone complementary to the wall 24. This internal cone connects with its narrowest position directly to the end channel 8. The seat 51 and the member 50 have the same size or conical angle similar sharpening, in its axial movement the seat 51 separates from the member 50. Thus it abuts the end wall of the part 25 in the wall 24. An axial channel 59, joins the channel 29 with the recess between the end or end walls. The channel 59 can exclusively be formed by at least one groove in the inner periphery of the sleeve 23, and along the open longitudinal side of the groove is limited by the outer periphery of the reduced, stepped end section of the core 25. In this way an acceleration or whirling of the medium occurs. The core 26 can here be rigidly mounted, for example by a one-piece connection with the unit 5, 20. This connection can also have in the elastic section 37 the shape of a tongue, membrane or the like, and be approximately in the plane of the plate 20. the section 37 forms within the member 21 a front wall with a passage for the medium. The carrier 58 is axially tensioned between that front wall and the wall 41. The channel 28 is narrowed in the direction of the conical flow to the seat 51. The return spring of the valve seat 51 towards the closed position can also be provided, so that at the beginning of the supply drive, first a lot of air flows in the opening 8, then by a simultaneous reduction of that air stream, the middle current starts and in connection with its termination the air current is increased again. All the embodiments according to figures from 1 to 7, can be combined with each other. All the properties explained can be provided exactly as described or approximately this is essentially, where the functions explained each time can also be caused by other means. The members constructed in one piece could also be separate parts, which are joined together in a fixed manner.
