Definitions

  • the invention relates to a bottle discharge head, in particular a spray head or the like. for pharmaceutical preparations, with a manually operable piston pump, which has a circumferential projecting over a pump housing, annular mounting flange for the sealed engagement with a bottle neck or the like. Has formed connection piece.
  • the invention has for its object to provide a bottle discharge head of the type mentioned, which makes it possible in a simple manner, without separate components and compact dimensions to make a secure attachment to the bottle neck.
  • the fastening flange is designed as a snap ring which can be latched into an inner groove of the connecting piece under at least partial radial prestress.
  • the snap ring which can be formed in one piece with the pump housing in a simple manner, is thus secured in a sealed manner directly in the interior of the connecting piece, without any additional component being required for this. This also enables a particularly simple and quick assembly of the discharge head.
  • the training according to the invention is particularly suitable for particularly small active ingredient dispensers. where compact dimensions are important.
  • at least one peripheral surface in particular an approximately cylindrical peripheral surface facing the pump inlet and / or an approximately frustoconical phase surface of the snap ring adjoins the pump outlet radial clamping surfaces for the directly sealing contact are formed on counter surfaces of the inner groove, so that the piston pump is precisely centered and a high sealing pressure is ensured by slight radial elastic expansion of the connecting piece.
  • At least one end surface in particular the end surface which is flat at least in the radially outermost region and / or the chamfered outermost region of the other end surface of the snap ring is located at the radially outermost region up to radially inner boundary of this radial surface are designed as axial clamping surfaces for the direct sealing contact with counter surfaces of the inner groove, the radial extent of the axial clamping surfaces preferably being smaller than the axial extent of the radial clamping surfaces.
  • the piston pump or the snap ring is also precisely fixed in the axial direction and, with a slight elastic expansion of the connecting piece in the area of the inner groove, there are further sealing surfaces which bear against one another with high sealing pressure.
  • a particularly advantageous development of the subject matter of the invention consists in that the peripheral edge of the snap ring lying towards the pump inlet, or the like, when the piston pump is pushed in at an end conical cone at the end. of the connecting piece, the sliding and prestressing edge is formed, an essentially cylindrical inner section being preferably provided between the pointed cone and the inner groove.
  • the inner and / or the outer circumferential surface of the pump housing lying adjacent to the snap ring is contact-free up to the snap ring under the radially inner boundary of an annular gap, the outer annular gap preferably being narrower than the inner one, so that even with possible guaranteed small tilting positions of the piston pump relative to the connection piece is that the snap ring engages tightly in the inner groove.
  • the design according to the invention which does not require any separate sealing element in the area of the snap ring, is also particularly suitable for non-symmetrically designed bottles or for bottles which are produced by the injection blow molding process.
  • the discharge head is further developed in such a way that a discharge and actuation button arranged on the outside of the piston pump is at least in one axial position, in particular in all axial positions, limited in rotation in the direction of rotation in, preferably concealed, engagement with the connecting piece .
  • the actuating button is always immovably aligned with respect to its rotational position about the central axis of the connecting piece or the piston pump.
  • the actuating button is designed as a tongue and groove in engagement with the connecting piece, which is preferably on the inner circumference of a union sleeve inside the cap casing and / or outside of a connecting sleeve fastened to the pump tappet for the connecting piece has at least one, in particular two diametrically opposed spring bars, which engage in axial grooves on the outer circumference of the connecting piece.
  • the axial guide acting as a rotation lock is on the one hand completely inaccessible and invisibly covered and on the other hand it lies on a relatively large diameter, so that a high mechanical strength can be achieved even with thin-walled dimensioning of the actuating button.
  • the union sleeve also prevents dirt from entering the interior of the connection piece and protects the connection piece from damage.
  • the sleeve can be used by the inventive design to limit the stroke of the actuating button when the free end of the sleeve forms a stroke stop surface for the actuating button, which is preferably assigned as a counter surface an annular shoulder that starts from the inner end of the connecting piece and / or is overlapped on the outer circumference by the cap jacket.
  • the stop surfaces are completely covered on the inside inside the actuating button.
  • the outer end face of the pump housing lies approximately in the plane of the free end face of the connecting piece and / or if the cap jacket, like the cap jacket, protrudes freely from and against the cap end wall In the initial position of the actuating button, the cap jacket of the shorter union sleeve only overlaps the connecting piece over a fraction of its length.
  • one counterpart for the latching and / or locking members on the circumference of the section of the connecting piece overlapped by the coupling sleeve in the starting position is one up to the associated one Groove reaching circumferential groove provided in the bottom surface thereof in connection with the associated flank of the groove has a projecting latching cam and on the side facing away from the groove flank forms a locking recess for the spring bar, wherein the locking recess is preferably wider than the groove and / or the R astnocke converging latching flanks having.
  • the lock can be overcome sufficiently smoothly despite a secure hold and, based on the different movement play in the circumferential direction in both locking positions, it can be easily recognized without actuating the actuating button whether the actuating button is in the rotational position required for the actuation or the axially locked rotational position.
  • a bottle discharge head 1 has one with an actuation button 3 provided, in a connecting piece 4 of a bottle 5, a container or the like.
  • Piston pump 2 used.
  • the substantially cylindrical connector 4 is formed by a reduced diameter end portion of the bottle neck 6, which passes over an annular disk-shaped transition wall 7 in the connector 4 and at the other end by appropriate, gradual expansion forms the actual bottle 5 or the storage container for the active ingredient .
  • the piston pump 2 has a substantially axially symmetrical pump housing 8, which is sealed at the end lying within the connecting piece 4 with a housing cap 9, the housing cap 9 being penetrated by a pump plunger 10 which is overlapped by a connecting piece 11 of the actuating button 3 and inside has a discharge channel for the active ingredient, which is connected via the connecting sleeve 11 to a discharge opening 12 of the actuating button 3.
  • the piston pump 2 has a snap ring 13 which protrudes radially about its thickness radially beyond the housing cap 9 and which can be formed in one piece with the main body of the pump housing 8, but preferably in one piece with the housing cap 9 is trained.
  • the massive snap ring 13, which is provided as an annular fastening flange, has a cylindrical circumferential surface 16 which extends over approximately two thirds of its axial extent and which essentially connects with sharp edges to that end face 17 of the snap ring 13 which faces the pump inlet 14 of the piston pump 2 located in the bottle 5 .
  • This circumferential surface 16 merges at its end facing the opposite pump outlet 15 formed by the end of the pump plunger 10 into a frustoconical circumferential surface which is separated by a phase surface 18 with a phase angle is formed by about 45 ° or by a correspondingly rounded phase surface and extends to the other end face 19 of the snap ring 13.
  • the connecting piece 4, which is approximately twice as long as the housing cap 9, has approximately in the middle of its length inside an annular inner groove 20 which is complementary in cross section to the radially outer, the peripheral surface 16 and the phase surface 18 forming the ring edge of the snap ring 13 is adjusted.
  • the greatest depth of the inner groove 20 is equal to the radial extent of the phase surface 18.
  • the associated end face 17 of the snap ring 13 abuts the associated side surface of the inner groove 20 over a radial dimension that is equal to the radial extent of the phase surface 18.
  • the snap ring 13 thus engages in the inner groove 20 in cross-section with three surfaces lying at an angle to one another, all of these surfaces lying against the boundary surfaces of the inner groove 20 with prestress.
  • the inner peripheral surface of the connecting piece 4 forms a cylindrical inner section 21, the inner diameter of which is slightly larger than the outer diameter of the housing cap 9 and larger than the smaller outer diameter of the main body of the pump housing 8 than the housing cap 9.
  • the inner groove 20 is provided approximately in the middle of the length of this inner section 21.
  • an inner pointed cone 22 adjoins the inner section 21, which is expanded to the outer end of the connecting piece 4 and has an inner diameter at this outer end of the connecting piece 4 which is slightly larger than the outer diameter of the snap ring 13 is in the region of the peripheral surface 16.
  • the peripheral edge 23 between this peripheral surface 16 and the end surface 17 of the Snap rings 13 serve as a sliding and prestressing edge when the piston pump 2 is inserted into the connecting piece 4.
  • the piston pump 2 is attached with the peripheral edge 23 to the conical cone 22 constricted in a funnel-like manner and then subjected to an axial load such that the peripheral edge 23 slides along the pointed cone 22 the connecting piece 4 is expanded approximately by the radial extent of the phase surface 18 and / or the snap ring 13 is compressed radially by a sufficient amount until the snap ring 13 slides with its peripheral surface along the inner section 21 and finally jumps into the inner groove 20.
  • the radially inner boundary 24 of the phase surface 18 then lies on the inner diameter of the cylindrical inner section 2.1.
  • the axially inside of the snap ring 13, formed by the main body of the pump housing 8, defines an annular gap 27 in the assembled state, while the axially outer circumferential surface 26, formed by the housing cap 9, delimits the annular gap 28, so that the piston pump 2 is excluded is completely contact-free in the area of the snap ring 13 with respect to the connecting piece 4.
  • the outer end face of the housing cap 9 or the pump housing 8 lies approximately in the plane of the free end face of the connecting piece 4.
  • the actuating button 3 is designed as a cap, which carries three concentric lugs on an outer, approximately flat end wall 29, namely as the innermost lug the connecting piece 11, then a union sleeve 30 surrounding the latter and a cap jacket 31 also surrounding it at a distance.
  • the inner diameter of the union sleeve 30 is adapted for the telescopic overlap to the outer diameter of the connecting piece 4, while the cap jacket 31 is adapted for the corresponding overlap with the outer diameter of the bottle neck 6.
  • the union sleeve 30, which axially protrudes relative to the cap jacket 31, instructs their cylindrical inner circumference on two diametrically opposed, axial web-shaped springs 32, which each engage in an axial groove 33 on the cylindrical outer circumference of the connecting piece 4.
  • grooves 33 extend essentially over the length of the connecting piece 4, that is to say they extend as far as the outer end face of the transition wall 7 forming an annular shoulder-shaped counter surface 34.
  • the free end of the union sleeve 30 only engages over the connecting piece 4 on a fraction of its length.
  • each groove 33 merges at a flank 35 into a circumferential recess 36, which extends over an arc angle that is several times larger than the arc angle of the groove 33.
  • the circumferential recess 36 has, following the groove 33, a locking cam 37 projecting over its bottom surface by less than the depth of the circumferential recess 36, which extends over an arc angle which is larger than the arc angle of the groove 33 and is approximately twice as large in the exemplary embodiment shown, and with a cylindrical peripheral surface is provided.
  • the latching cam 37 is adjoined by a latching recess 38 which is approximately as deep as the groove 33, but is wider than this.
  • the side flank 39 of this groove 38 formed by the locking cam 37 converges with the other flank 35 radially outwards at an acute angle.
  • the other flank 40 of the latching recess 38 which is provided as the end flank of the circumferential recess 36, lies in contrast in an axial plane of the connecting piece 4 and extends to its outer circumferential surface.
  • the groove 33 is approximately trapezoidal in cross section, being widened radially outward at an acute angle and symmetrical to its central plane. If the springs 32 lie in the grooves 33, the actuating button 3 for executing the pump stroke of the piston pump 2 is axially displaceable until the union sleeve 30 completely engages the connecting piece 4 and with its free end face, which forms a stroke stop surface 41, bears against the counter surface 34.
  • the actuating button 3 can be rotated relative to the connecting piece 4 by the fact that the inner ends of the springs 32 are only in the region of the circumferential recesses 36 so that the springs 32 jump into the latching recesses 38 after the latching cam 37 has overrun.
  • a certain locking force must be overcome, since the springs 32 are located slightly further radially inward than the peripheral surface of the locking cam 37.
  • the actuating button 3 is secured against axial displacement, since the end faces 42 of the springs 32 'are blocked by the shoulder face 43 delimiting the peripheral depression 36 on the side of the peripheral depression 36 opposite the free end face 44 of the connecting piece 4.
  • the outer end face of the pump housing 8 is designated 45.
  • the cap jacket 31 overlaps the bottle neck 6 on a section which is only slightly larger than the thickness of the transition wall 7, but the cap jacket 31 lies only with a very small gap distance from the outer circumference of the bottle neck 6. This prevents dirt from entering the interior of the cap shell 31.
