Definitions

  • the invention relates to closures for bottles or the like, according to the preamble of claims 1 and 2.
  • a closure according to the preamble of claim 1 is known from FR-PS 1 343 505.
  • the walls of the cap forming the storage areas are formed by a shaft which is open at the top and is closed all round.
  • the storage areas must be displaced by a considerable amount when installing the rocker arm. This requires relatively soft, resilient material.
  • the stub axles of the rocker arm are chamfered on the face to the stub foot.
  • the bevel extends only over a partial cross section of the end face, thus leaving a crescent-like residual surface of the basically cylindrical stub body unslanted. As a result, a full lateral surface remains on the circumferential side in a partial jacket region, but this then continuously decreases rapidly.
  • the area-reduced lateral surface parts of the stub axles do not come into a critical support area in which, for example, the wedging end zone of the run-up slope would have to bear the bearing load, which in the worst case would result in the rocker arm falling out of its storage.
  • the low rocker arm folding angle is disadvantageous; the rocker arm cannot be moved into a hiding position; rather, it maintains an exposed location. This can be caused by unintentional opening, for example by accidental touching causes drying of the medium in the bottle or container.
  • the mouth of the passage opening of the rocker arm on the container side is located in a jacket zone of the rocker arm that runs concentrically to the rocker arm axis.
  • the corresponding outlet opening in the cap base forms a lip sliding over it.
  • the entire cap base is designed as a spring zone, which has a certain preload, so that there is contact pressure in the assembled state.
  • the cap base has a considerable thickness, so that in this regard, too, very soft, flexible material has to be used, which, however, can lead to immediate wear, so that the desired sealing becomes problematic. Since, moreover, the edge part of the cap base is already part of a connection piece, the movement forces are transmitted into the piece body with the disadvantage of a risk of leakage even between the piece and the container.
  • DE-PS 26 58 590 on a closure also in accordance with the preamble of claim 1 suggests that the resilient system pressure should not be obtained from the pretensioned cap base, as described, but from the material of the rocker arm.
  • This rocker arm which can even be moved into a hiding position in the closed position, forms a wall section that runs concentrically to the tilt axis and has a cavity in its back.
  • the relevant wall part which closes the lip of the outlet opening in the closed position, acts differently, depending on the rotary position of the rocker arm, i.e.
  • the axle stubs that are also formed on the rocker arm are under load when the rocker arm is closed in the opposite direction to the cap-side outlet opening, that is, in the direction of the open ends, the cap-side plug-in slots are located on the transverse side to the spout channel, the minimum clear width of which is slightly less than the diameter of the cylindrical axle stub .
  • the rocker arm can slip out at high clamping pressure.
  • the support surface for absorbing the bearing pressure is very small. Tolerance deviations can also lead to impairment of the waxing and thus to the tightness.
  • the depth of the insertion slots measured in the direction of the rocker arm axis corresponds to the axial length of the axle stub. However, the unity and stability of the storage area is lost due to the insertion slots.
  • Plug-in slots are also provided here, however, which are of a smaller axial depth than in the case of the second runner discussed.
  • the open entrance of the plug-in slots has a bevel which interacts with a corresponding bevel at the front ends of the stub axles.
  • this bevel does not wedge out at the foot of the stub axle, so it leaves a still, albeit narrow, supporting jacket wall section.
  • the insertion slots are located here at the end of the rocker arm facing away from the grommet opening.
  • the stub axles are supported on their rear by a stiffening wall.
  • the object of the present invention is to improve a generic closure with regard to the assembly of the rocker arm, while optimizing the sealing conditions of this closure.
  • the outlet opening is designed as a mouth collar, which is molded onto the cap base via a transition region with a cross-sectional cross-section in its root region.
  • a muzzle collar behaves as it were floating, but without stepping into a constellation caused by friction, for example.
  • the muzzle collar is assigned in one piece like sitting on a membrane.
  • the height of the mouth collar corresponds approximately to the inside diameter thereof, the wall thickness corresponding to approximately half of the inner diameter.
  • the portal columns or webs it has proven to be advantageous for the portal columns or webs to have an extension in cross section pointing in the direction of the stub axle.
  • the invention also proposes that the rocker arm have groove-like shapes adjacent to the stub axles in its cylindrical bearing area and that, associated with these, webs are formed in the cap. They are also limited in length to the top of the rocker arm. When the rocker arm is upright, the ends of the formations cooperate with the ends of the webs in order to ensure a defined upright position of the rocker arm and thus a precise alignment of the passage opening and the outlet opening in the open position.
  • Part of the closure 1 is a cap 2 with a rocker arm 3 stored therein.
  • the closure 1 sits on a housing designed as a standing vessel, for example a bottle 4, which contains the substance 5 to be dispensed, such as liquid soap.
  • a housing designed as a standing vessel, for example a bottle 4, which contains the substance 5 to be dispensed, such as liquid soap.
  • the bottle is placed in a tilted position or finally held upside down.
  • a so-called bottle neck emerges from a neck 7 projecting from this ceiling 6, into which a connecting piece 8 of the cap 2 engages in a sealing manner.
  • the cap 2 is in a plug-in / snap-in connection with the stepped portion of the ceiling 6.
  • the snap-in zone bears the reference number 9.
  • the cap 2 forms a recess 10 which is open at the top. This is formed, essentially in accordance with the outline of the rocker arm, by deep-drawing the cover 11 of the cap 2.
  • the top of the rocker arm 3 is essentially level with the top of the above-mentioned ceiling 11 (see FIG. 4).
  • Only the free end of the rocker arm 3 protrudes laterally slightly over the oval or elliptical cross section of the ceiling and serves as a gripping bottle 12. Below the gripping bottle 12, the narrow bend of the cap wall there forms a slight depression 13 in order to be able to grasp the gripping bottle 12, which protrudes only slightly, nevertheless comfortably.
  • a suspension hook 14 is formed in the area of the opposite, narrow bend of the cap wall, for example for assigning the usual carrying cord.
  • the rocker arm 3 designed as an output spout, correspondingly having a through-channel 15, swings about a horizontal axis x-x lying in the plane of the shorter ellipse axis of the cap 2.
  • the corresponding bearing areas are formed within the depression 10.
  • These are two bearing portals 16 which are transverse to the axis xx.
  • Their parallel columns 17 are rooted in or on the side wall 18 near the bottom of the depression 10.
  • Their free-standing assignment is particularly clear from the Perspective Fig. 9. Almost the entire height of the two parallel side walls 18 is used to form the bearing portals 16.
  • the bearing portals 16 sit on the outside of said side walls 18; Extends in the form of vertical strips 19 pointing only in the direction of the depression 10 lie in the cross-sectional area of the walls 18.
  • the strips 19 are arranged in pairs. They give the columns 17 practically a rectangular or T-shaped cross section. The bottom ends of the strips 19 are rooted in a parapet 20, but do not exceed the transverse width of the depression 10 with their inward-facing narrow edges.
  • the strips 19 are rounded transversely at the top.
  • the strips 19 form a type of guide shaft 21 for the stub axles 22 to be connected to the bearing portals 16 and formed on both sides of the rocker arm 3 in the area of the axis xx.
  • the stub axles are cylindrical in shape. Your forehead surface can be flat. The edge may have a chamfer.
  • the cover 11 of the cap 2 accordingly has pockets 23 which also prove to be advantageous in terms of shape.
  • the pockets 23 are open towards the interior of the depression 10, design-wise capture the walls 18 and, as already indicated, a partial area of the ceiling 11.
  • the side walls 18 as well as the bearing gantries 16 take a slightly diverging upward path, that is to say a mold which is favorable for demolding.
  • the pillars 17 of the bearing portals 16 are cut back to the parapet 20 lying just above the bottom 24 of the recess 10 and moreover provided with an outer lateral pillar reinforcement 17 '.
  • this type of complete three-sided free cut F is not selected. There, the free cut F ends approximately halfway up the pillars 17.
  • the reinforcement 17 ' runs back to the height of the portal lintel 25 and is rooted in the ceiling 11.
  • the portal lintel faces the tapered stub axles 22.
  • the portal lintel 25 of both bearing portals 16 forms on the inside a run-up slope 26 for the axle stub 22.
  • the inclination is approximately 45 degrees and favors the deflection of the bearing portals 16 springing back into the basic position.
  • the bearing portals 16 Under the portal lintel 25, the bearing portals 16 form an arcuate surface 27 corresponding to the cylindrical contour the stub axle 22, the outer surface of which is overlapped in half over the entire axial length. This wide overlap is retained in every angular position of the rocker arm 3.
  • the coupling allocation level lies in the vertical V. The desired uncoupling is effected by deflecting the bearing portals 16 while pivoting about their column feet.
  • the articulation area of the rocker arm 3 is designed in a circular arc shape between the two axle stubs 22 over an area of more than 260 degrees in the swivel plane concentric to the x-x axis. This area forms a sealing surface 28.
  • the inverse, somewhat reduced cross-sectional area of the through channel 15 opens into the latter. This end area thus forms a through opening 29 for the substance 5 and is designed as a longitudinal slot. Its direction of extension is parallel to the axis x-x.
  • the passage opening 29 can thus be appropriately closed by pivoting the rocker arm 3 or in congruent alignment with an outlet opening 30 of the housing or bottle 4 arranged in the area of the connecting piece 8.
  • the latter opening is longer than the passage opening 29 and from a box-shaped mouth collar 31 circumscribed. It is rooted in the bottom 24 of the depression 10. It projects beyond the bottom in the direction of the axis xx and is connected to the bottom wall via a web-like transition area 32.
  • the web-like transition area 32 which extends around the mouth collar 31 without interruption, has only a fraction of the thickness of the base and is therefore flexible in the manner of a membrane.
  • the lip edge of the muzzle collar 31, which is tapered on the rocker arm side, thus lies tightly against the sealing surface 28.
  • the related type of floating connection contributes to the desired sealing, so that neither losses occur nor unsightly incrustation occurs in the rocker arm area. Deformation forces also do not continue into the floor 24 and the walls or vice versa.
  • the height of the muzzle collar 31 corresponds approximately to the inside diameter (measured in the transverse direction of the elongated outlet opening 30) of the muzzle collar. About half of this dimension is accounted for by the wall thickness of the mouth collar 31.
  • the formations 33 are open to the end faces of the sealing surface. They are also limited in length to the top of the rocker arm 3.
  • the ends 50 of the formations 33 there cooperate with the rocker arm 3 erected with the ends of the webs 35 in order to ensure a defined upright position of the rocker arm 3 and thus a precise alignment of the passage opening 29 and the outlet opening 30 in the open position.
  • a cap-side latching projection 37 snaps into its grommet 36. This latching can only be overcome by swiveling the rocker arm 3 in a manner that is emphasized, so that there is no fear of self-loosening when the dispenser is carried in a pocket.
  • the flexible, cut-free material section forming the locking cavity can carry the axle stub 22, whereas the corresponding bearing cavity is realized on the rocker arm.
  • the stub axles are appropriately seated on spaced webs extending from the parapet 20, approximately corresponding to the columns 17.
  • the functional difference is that in the exemplary embodiment described above the bearing pressure acts on the upper jacket half of the axle stub 22 facing away from the parapet 20 and, in the variant not shown, on the jacket half facing the parapet 20.
  • the portal-like clearance in the coupling direction creates in addition to the material savings mentioned, a certain allocation clearance comparable to an elongated hole.
