Abstract

The two main components (2, 3) are initially connected together by a deliberate weak line (4) at a connecting zone and the module forms a channel or nozzle unit with an opening for guiding the dispensed item when both parts are in the operational position. At least one component forms a shear zone (34) which breaks the weak connection when one of the components is pressed out of its original molded position. An Independent claim is made for a process for injection molding the dispenser module and then separating both parts by shearing at the weak line. Preferred Features: The shear zone comprises shear faces (21, 25) sliding in intimate contact with each other and the connecting weak line links the shear surfaces (21) of one component to a transverse leading face (29) of the other component. The connecting line is at the front end of the moving component (3) in its direction of movement. When the weak line is broken the moving component slides in a play-free guide which starts at the shear zone and permits movement of the moving component in the operational direction only. The guide is open on one side and only when the moving component is in the dispensing position does it cover and guide the front end of the component on all faces.

Description

The invention relates to a dispenser for media or a Process for making a media dispenser. Such Media can be in piece form or flowable media, the gaseous, liquid, pasty, creamy or powdery or are free-flowing. The donor is expediently one-handed to wear and with the carrying hand at the same time for the Press media release. He can only do this for the one-off Media discharge or for any repeatable media discharge be provided. For example, it can by itself return to its starting position after each discharge. Appropriately, the, most or all exist Components of the dispenser made of plastic or injection molding, the is insensitive to the medium.

Interacting and therefore more complicated components of the Donors are usually made separately and then together assembled. This requires a lot of effort. Even if the components are made in one piece, then by separation isolated and only assembled afterwards. Appropriately it is therefore not only to manufacture the components in one piece, but rather towards a separation after production dispense with them directly from their mutual production to transfer into their mutual operating situation. In the operating position, the components can move against each other be, i.e. occupy several operating positions; You can also be rigidly connected. In this manufacture, the Disrupt fragments of the severed connection. You can Guide surfaces or other surfaces with their parting surfaces to damage. The dividing or breaking surfaces can vary depending on Separation behavior have different, such as jagged, shapes and require recording space in the operating position.

The invention has for its object a donor or a method for producing a structural unit for a To create dispensers or the like, in which disadvantages are known Avoid training or the type described or the mentioned advantages can be achieved in a convenient manner. In particular, separable surfaces that can be determined as precisely as possible should be can be created when severing the connection. Furthermore, the dispenser should be easy to manufacture and in Operation be safe.

According to the separable connection between the two components, for example, by shear or one other equivalent separation process solved. By the at Divide the cutting force curve occurring in the connection is a slight plasticization of the connection material and to achieve a crack-free or smooth interface, without particles detaching. The maximum shear stress only the shear yield point of the connecting material to reach. In a state of tension, at to which the higher shear fracture limit is reached, the separating surface, on the other hand, can become grainy and rough. Shear cutting is particularly easy to achieve if the two Components as stamps and cutting bushes analogous to a punch are trained.

The training according to the invention is for numerous components a donor or the like. E.g. can the components two housing parts, such as a main housing and a cover of one Pressure cylinder, a pump, a valve, a piston unit, a discharge head or the like or two valve bodies be. Furthermore, the components can be sections of a line for be the medium. The components can be transverse or parallel divided on its axis or against each other in the operating position be transferable.

The training according to the invention is particularly useful for an outlet or nozzle unit, the nested one inside the other Components or nozzle bodies for single or multiple Serve transverse deflection of the medium. To include the Features and effects in the present invention are based on EP-A-790079.

The connecting link is expediently a projection. He closes in one piece directly on two, at an angle to each other, smooth surfaces of the two components. It extends to the common corner zone of these areas. He connects them Surfaces over an inclined surface. It can be flat, concave or be convexly curved. The projection is therefore in cross section triangular or isosceles. His thighs connect the mentioned pads of the two components.

The link is spaced from one or both surfaces of the respective component facing away from each other. These areas connect to the associated connection area across. So step into this when cutting No broken surfaces. These areas form with the Pad edges, which are similar to a micro-thin Connection directly to the corresponding edges of the other Connect component. This tack connection has over the Link a much lower strength, such as Shear strength. So it can be practically without additional Force is also exerted by shear or shear cutting be separated. It can already be separated if that Link is not yet completely cut. Only a single connecting element is expediently provided. Also can only on two opposite sides opposite links provided be. Such connecting links are missing on the transverse sides, however, the stitches are provided here. The micro-thin stitch can therefore be arched or ring-shaped be closed. Adjacent edges are sufficient of both components directly at each other at a sharp angle. So can the associated inner surface of a component on the associated one Edge joint in cross section straight into the outer surface of the other component.

The largest cross section of the connecting element is expedient under two, one, half or two tenths Millimeter. The length of the connecting leg can e.g. be a tenth of a millimeter. Over its length the connecting link expediently has constant cross sections on. This length is also less than one of the above Values, especially a third millimeter, so they larger than all edge dimensions of the cross section of the connecting link is. Polyethylene is an advantageous material or a material with similar properties.

To secure the components in the operating position are advantageous Locking or snap links provided. You jump in Reaching the operating position spring back in mutual, positive engagement. Before reaching this working or Operating position they push each other back springy. It is only one snap member is resilient, while the other is rigid remains.

In the operating position, the respective component can also Secure the stop on the other component. That attack acts against the locking action of the locking member. The attack one component only comes on a last one small part of the entire displacement path in contact with the other component.

The adjoining corner edges of the two components or the associated microconnection can also not be ring-shaped be. For example, they are angled along one continuous edge interrupted. Accordingly, the as Cross-section of the guide sleeve serving as a cutting sleeve be open to this page. The shape is then the one to be recorded Component on this side on a first part of the Movement path not led at all. Then he kicks in a guide part, which also on this side leads positively. In view this guide page overlaps on the left and on the right. In between, it is exposed. Between the leadership tabs a media outlet is formed. It goes from the opposite Guide surface of the receiving component from and penetrates the recorded component in a straight line. Between The medium flows through these guide surfaces of both components.

The connector is complete after severing only on a single one of the components, in particular on the recorded one Component, provided. The other's interface Component serves as a sliding surface over the entire displacement path for the first named component and secures it Operating situation due to permanent concerns. For this as well as the other mentioned modes of action are the cold flow properties of the material used. From the edge or Width dimensions of the component to be accommodated, which on the Connection zone to be measured perpendicular to the direction of displacement, is the largest under thirty, twenty, ten or five millimeters. The smallest of these dimensions is under five, three, two or a millimeter. The component is therefore a chip and non-destructive, flexible or flexible. In the operating situation is then due to the other component rigidly stiffened. A media channel that this component has a minimum width of less than three, two, a millimeter or a half. The channel is with one Angle less than 5 ° or 2 ° conical. This makes it suitable Passage as atomizer nozzle. It either forms the ins Free opening media outlet or it is upstream in the Distance from it.

According to the invention there is also a method of manufacture proposed by a donor. The components molded in one piece with each other in an injection mold or the like or poured. After that, they remain in without interruption mutual connection. They will be the first Layer, i.e. the shape, in a second layer, i.e. the Operating situation, transferred. Instead of a common one The two components can also be molded in a separate cavity Form cavities or without mutual connection getting produced. Then they will be in the first position first and then transferred to the second position.

All parts according to FIGS. 1 to 6 form a structural unit 1 and are made in one piece. The components 2, 3 are the cap-shaped discharge and actuating head Piston unit of a pump of the type mentioned and in it second component to be recorded 3. That for the respective Component 2 or 3 can also be said for the other component be valid. Part 3 is in the first layer and manufacturing form quasi completely and freely above component 2. The parts 2, 3 are immobile only via a stitch or connection 4 connected. Only after separation or destruction of the Stitch 4, part 3 is displaceable relative to part 2. Then the outermost surfaces of part 3 close flush and without gaps to the corresponding outermost surfaces of the part 2 on. The areas are then continuous continuations.

In part 2, a guide 5 is provided. It is used for Shift and lies immediately after the Stitch 4, which is partially covered by the guide 5. The first and outermost longitudinal section of the guide 5 forms a cutting or perforated sleeve 6 of a punching tool. The immediately as well as the end of the part following it alone 3 forms the associated slide or punch 7. So is already with the beginning of the mutual movement Stitch 4 sheared smooth. The guide 5 is immediately adjacent to the inside of an outermost jacket 8 of the Part 2. Inside the jacket 8 and with a radial distance An inner jacket 9 is coaxial with it in the same direction free before. The jacket 9 stands back from the jacket 8 and is shorter. In the jacket 9, the piston skirt becomes one Piston unit added. It is from one in the coat 9 penetrating outlet channel. The central axis 10 of the Part 2 is then in the central axis of the pump. From the Part 2, the medium emerges outdoors in axis 11, the perpendicular to axis 10.

In the second position, part 3 is parallel to axis 10 in Direction 12 and against flow direction in the jacket 9 postponed. The axis moves from position 11 'to Position 11. In all situations, part 3 on part 2 is in all Directions 13, 14, which are transverse to direction 12, free of play or it is a cross game of at most two or one Provided tenths of a millimeter. This makes the location of the two parts 2, 3 precisely defined over the entire path 15. In the form position, parts 2, 3 of a plane 16 close to each other, which is perpendicular to the direction 12 perpendicular and is parallel to axis 11. The level is 16 Connection 4 in direction 12 only by the specified edge dimension of Connecting links. Level 17 is on level 16 at right angles across or parallel to axis 11 and is one Axial plane of the axis 10, 11 or a plane of symmetry of the Part 2 and 3. Fig. 4 shows dash-dotted parts of Tool 18, 19 or the injection mold or of their Trains. 4 also shows the second layer in broken lines of part 3. Parts 2, 3 are by means of securing means 20 immovably secured against each other.

The guide 5 is flat rectangular in cross section. she is of four at right angles as well as guide surfaces 21 to 24 each lying in one plane limited. The flat plate 7 has one for each of these surfaces Counter surface, namely a sliding or guide surface 25 to 28. Each of these areas is also continuously in one level. Two surfaces facing away from each other are continuous parallel edge surfaces 25, 26. The other two Areas are the large plate areas 27, 28. All areas 25 to 28 adjoin a front or chest surface 29, which points in the direction of 12 and the foremost edge surface of the Stamp 7 is.

The surfaces 21 to 24 form edges in the plane 16, namely a continuous sharp edge. Also the Surfaces 25 to 29 form sharp edges, which in plane 16 with the sharp edges of part 3 via a micro connection 30 are connected in one piece. This stitch has 30 a thickness of less than one or half a tenth Millimeter. In addition to the stitch 30, the connection 4 only two opposite connections in the form of Break down 31. These are at most 1½ tenths of a millimeter over the inner surface 21, 22 or surface 29. The Links 31 connect in one piece to each of these surfaces. At the Stamp 7 form the surfaces 25 to 28 with the surface 29 Edges 32 to 35. Each link 31 forms a continuation one of the edges 25, 26 and is decreasing in the direction 12 via the associated surface 21 or 22. On this surface 21 or 22 includes the link 31 continuously and in one piece a pad 36 on. This closes the surface 29 Link 31 with a correspondingly continuous connection surface 37 on. In this way, connecting legs 36, 37 of the same length are formed. The link 31 is triangular in cross section at right angles. It forms a flat base edge 38, which surfaces 21, 29th or 22, 29 connects directly.

The surface 24 faces the axis 10 and is parallel in view open towards U 13. The area 24 is through a U-shaped projection 39 of part 2 is formed. This will the part 3 with the surface 28 only along edge strips led, which connect to the surfaces 25, 26 and 29. Part 3 is also held in the operating state. For Transfer to the operating position, part 3 has a printing surface 40, which points away from the surface 29. The area 40 is the extreme end of part 3 and of connection 4 away. Excludes breakthroughs and a thickening 41 the part has 7 outer cross-sections that are continuous are constant. The thickening 41 is at the extreme end formed a protrusion 42. It points from the axis 10 in Direction to the outer circumference of part 2 away and forms the much shorter leg of the angle plate 3. The projection 42 only projects over surface 28. He helps its inside a stop 43, which for connection 4 points. Part 2 forms a recessed pocket 44 which lies between the surfaces 21, 22 and on the plane 16 in Direction 12 connects. The pocket 44 takes the protrusion 42 completely on. For this purpose, the side legs of the projection 39 set back in direction 12 relative to level 16. So the free ends of the side legs form the Pocket bottom or for the stop 43 a counter stop 45. In the operating position, surface 40 lies in level 16. Die Pages 25, 26 of the projection 42 then connect without gaps the side surfaces 21, 22 of the pocket 44.

The securing means 20 comprise snap members 46, 47. They are within part 2 when the operating situation is reached sunk and spring back into each other. Then reach behind they are form-fitting. The securing member 46 of the Part 2 is on the inside of the jacket 8, at the end of Guide 5 and following the surface 24 by the axis 10 is further away. The link 46 is separated by an inner or Shoulder surface formed, which is transverse to direction 12 lies. The securing member 47 of part 3 is about Surface 28 increasingly against direction 12. Link 47 adjoins surface 29 or edge 35, but not to the connection 30. The thickest area of the link 47 forms a securing edge for contact with the locking shoulder 46. A link 47 could also protrude over surface 27. The ends of the link 31 have a lateral distance of at least one tenth of a millimeter from the opposite Surface 23 or 24. Between the surfaces 23, 24 has link 31 a length at least two times greater than the length of its legs 36, 37 is.

Level 16 is through the outside of an end wall 48 Are defined. From her the coats 8, 9 are only in the direction 12 one piece free. The outside of the wall 48 forms the Pressure handle for operating the dispenser. The outside of the jacket 9, the inside of the jacket 8 and the inside the end wall 48 are together via a projection 49 connected. It is closer to jacket 8 than jacket 9 penetrated by the guide 5 and takes the in the operating state Part 3 completely. Part 3 is shown in FIG Direction 12 with the links 31, 47 via the crossbar 46, 49 in front. The projection 49 also forms the link 46. Following at the opening 6, which passes through the wall 48, the Projection 49 the longer part of the guide 5. This part is then only from the surfaces 23, 24, but not the Areas 21, 22 limited. The lead in this area 49 a width equal to the distance between the surfaces 25, 26. The latter are in this area Operating state free. In between is link 47. It runs non-contact between the side legs of the projection 39 through. 2 is the projection 49 T-shaped. Its T-crossbar is penetrated by the guide 5. His T-foot connects to the jacket 9.

Part 3 forms the media outlet 50, which is outside opens and with a distance between the side legs of the projection 39 and at a distance between the level 16 and the Cross leg of the projection 39 is. The inside of the coat 9 forms a media channel 51 which is circular in cross section is. The channel 51 goes on the bottom or on the inside of the Wall 48 into a narrowed transverse groove 52. Channel 51 is on to connect the outlet channel of the piston skirt. The groove 52 conducts radially and connects to a transverse channel 53, which is radial to axis 10. The channel 53 penetrates the projection 49 to area 23 and closes in operating position close to the surface 27 or the outlet 50, namely eccentrically to its axis 11 so that it is closer to level 16 lies.

The plate 7 is spaced between the surfaces 25, 26 on the one hand and between the surfaces 29, 43 on the other hand by penetrated a channel 54. It is in or against the flow direction flared. The diameter of the channel 54 is less than a micron or a half. The channel 54 is bounded in one piece by the plate 7 and forms in the Level 17 the nozzle channel of an atomizer nozzle, the one has a sharp end edge. In the surface 27 there is a depression 55 provided that is flat and spherical. In the Surface 28 is a corresponding spherical cap-shaped depression 56 provided the much larger width and has the same depth. Compared to this depth or that Channel 54 is twice or four times longer. Its ends close to the center of each Excavation 55, 56 on.

A guide device for the medium is assigned to the outlet 50, to the upstream end of channel 54 connects. It is a swirl device which is the medium set in a rotational flow about the axis 11 and with this flow leads directly into the channel 54. She points Guide wells 57 to 59, which form channels and only the Surface 23, but possibly only surface 27 or both Enforcing areas. The width or depth of the depressions is under two, one or half a millimeter. she comprise a circular annular groove 57 in the axis 11, inside which a circular bowl 58 and several, in particular at least three evenly around the axis 11 distributed transverse or tangential grooves 59. The channels 59 connect the channel 57 tangentially to the swirl chamber 58. All channels 57 to 59 have a common, continuous flat floor surface. The width of the channels 59 is less than the width or width of the channels 57, 58. The width of the Channel 57 is smaller than the width of chamber 58. The channel 53 opens directly into channel 57, namely with Circumferential distance between two channels 59. The width of the chamber 58 is equal to the width of the recess 55. Both are in Operation identical. The medium therefore flows out of the channel 53 between the surfaces 23, 27 initially in opposite Circumferential directions only in channel 57. Only then does it flow via the channels 59 radially inwards into the chamber 58.

During manufacture, the unit 1 is in the form 18, 19 as Injection molded. Then a tool part 18, the Surface 43 and a subsequent part of surface 28 forms, withdrawn. The remaining tool parts, which the Surfaces 25 to 28 remain in their shape; or you are lifted off the workpiece only briefly and then returned to their shape. At the same time the Tool part, which the guide 5, the surface 29 and the Links 31 forms, retracted and released the guide 5. With a tool stamp, for example with the Tool part for the surface 40, is then in the direction 12 pressed against surface 40. This will make the connection 30 and the legs 36 in the plane of the surfaces 21, 22 through Shear cutting sheared. The U-shaped edge 32 to 34 and the same U-shaped opening edge 6, which in the plane 16th are the cutting edges. The tool part, which the Link 47, the pocket 44 and between the side legs of the Projection 39 forms the gap, can also be slight retracted to undamaged limb 47 let pass. The sheared links 31 remain completely on surface 29. The associated parting surfaces 36 lead the surfaces 25, 26, which do not form a clearance angle, but consistently a cutting edge game tending towards the value 0 determine.

With increasing displacement 15, the tool part also 19 progressively withdrawn in whole or in part. So the protrusion 42 is allowed to pass, but the support and receive guidance on surface 28 before entering the Guide 5 dips. If the link 47 the crossbar of the projection 39 reached, it presses it against its own suspension back. So link 47 runs past and jumps on End of path 15 past surface 46. The edge of the protrusion is curved convex and forms in the view according to FIG. 3 a continuous continuation of the outer circumference of the Part 2. Via path 15, channel 54 runs at the mouth of channel 53 and past channel 57 until it reaches the cover position reached with the chamber 58. The workpiece 1 is then completely removed from the mold or released from the mold 18, 19.

Each of the surfaces 23, 27 alone can have a projection, such as have a bead, which is raised on the counter surface Pressing is present. The bead can be ring-shaped around the axis 11 and within it are channels 53 and 57 to 59 or their openings in surface 23. Are on both surfaces 23, 27 beads provided, their side flanks are expedient with pressure on each other. This is between the Surfaces 23, 27 better sealed.

The jacket 8 has protruding latching or Snap members 61 of a trigger protection. With the limbs 61 is the unit 1 after the axial connector the pump is positively secured against being pulled off. At the The links 61 are attached by means of inclined surfaces pressed on the outside, which run onto the counterparts and because of the self-suspension of the unit 1 are movable. The stop faces the links 61 then spring back behind corresponding counter surfaces. The links 61 are only in an axial plane that is perpendicular to plane 17. Of the Handle or outside of wall 48 is recessed provided that does not reach the guide 5.

All specified properties and effects can be precise or only provided essentially or as described be and depending on the needs stronger of it differ. Starting from an outer diameter of part 2 of at most 30 mm or 20 mm and a larger one Lengths of at most 40 mm or 30 mm are shown Dimensional ratios particularly favorable.
