Definitions

  • the invention relates to a dispenser for dispensing flowable, for example liquid or pasty, masses, according to the features of the preamble of claim 1.
  • a dispenser with a modular and exchangeable design of the dispenser pump is, for example, from the EP 1 015 340 B1 This design provides a compact dispenser pump that can be used with a variety of dispensers that can be freely configured in their head piece and storage container.
  • a dispenser in which the pump chamber has a pot part that is connected to an inner wall of a storage container.
  • mass is pressed into an outlet channel, which at the same time elastically pushes back a valve that closes a dispensing opening of the outlet channel, with a free space being assigned to the valve on the side facing away from the mass.
  • an air path is provided from the free space into the interior formed by the pot part and the piston part, which in turn has an air path to the outside.
  • the piston part is guided directly on a wall part which also forms an outer surface of the pot part.
  • a dispenser for dispensing flowable masses is known in which a circumferential, single locking bead is formed in the pot part, which is comparatively long in an insertion direction and which initially has a lower surface pointing obliquely outwards, then a middle surface running parallel to the axis and again an upper surface running obliquely inwards.
  • a dispenser which has two locking beads arranged one above the other in a longitudinal section, in which the upper locking bead is longer and the lower one is shorter. They each have a lower leg running at an acute angle to a longitudinal axis, which each merges into an axially parallel section. The axially parallel section in turn merges directly into a horizontally running contact surface.
  • the object of the invention is to design a dispenser of the type in question advantageously with regard to fastening.
  • each locking bead is initially provided with a leg which encloses an acute angle with an axis parallel to a longitudinal axis of approximately 30° to 45°, which extends opposite to the insertion direction and rises radially outwards, that the leg merges at the end into an insertion rounding, which in turn runs into the contact surface which, with reference to the longitudinal axis, runs approximately at right angles to the axis in the longitudinal cross section and which is correspondingly directed transversely to the insertion direction, and that, viewed in the direction of extension of a longitudinal axis, a height (a) of each locking bead corresponds to approximately one third to two thirds of the material thickness of the chamber wall, wherein the height dimension is
  • the dispenser pump can easily be combined with a variety of different storage containers during assembly during production. However, when a combination is made and the dispenser pump is locked into the storage container, a reliable, practically indetachable connection is created.
  • the dispenser pump can be connected to any storage container that is designed to suit the connection, while the connection formations on the dispenser pump and the storage container are still comparatively simple. In terms of manufacture, there is therefore still great freedom to choose between different dispenser pumps or different storage containers until the dispenser pump is actually joined to the storage container.
  • the reinforced locking connection between the dispenser pump and the storage container is secured by the two locking beads that are spaced apart from one another in a vertical direction and protrude radially outwards, with an insertion curve on the storage container side and a horizontal contact surface on the head piece side.
  • the reinforcement is further preferably selected such that, compared to the known locking connection, in particular the known locking connection from the aforementioned prior art, at least 1.5 times up to 3 or 5 times the force is required to release the locking connection.
  • the locking connection is preferably selected in such a way that it cannot be removed by normal manual force, i.e. without the use of tools and without causing any damage.
  • the locking beads can extend in a ring shape in relation to the longitudinal axis, corresponding to the full circumference of the part of the dispenser pump or storage container that has the locking bead.
  • the counter-locking part, corresponding to the storage container or the dispenser pump, preferably has locking grooves that are designed accordingly and adapted to the cross sections. These can also extend, as is preferred, over the full circumference.
  • the locking beads may extend only over a partial section of the circumference, whereby, viewed further over the circumference, a plurality of locking beads and locking grooves may be provided.
  • the spacing of the locking beads viewed in an axial direction preferably corresponds to 1 to 5 times, more preferably 1.5 to 2 times, the extent of a locking bead viewed in the same direction.
  • the two locking beads have identical cross-sections, both in terms of their geometric design and their axial and radial dimensions.
  • the rounded insertion area which is formed on the locking beads on the storage container side, has a supporting effect when attaching the dispenser pump to the storage container.
  • an edge surrounding the container opening as well as the locking groove initially formed in the insertion direction are advantageously overrun.
  • the contact surface on the headpiece side of both locking beads which is provided so as to run essentially horizontally with respect to the longitudinal cross-section, interacts in the locked fixing position of the dispenser pump on the storage container with a counter-contact surface of the locking groove, which preferably runs in the same direction, accordingly also essentially horizontally.
  • the locking beads are shaped like barbs, which supports the insertion and movement of the dispenser pump into the locking position on the storage container, but prevents the locking from being released.
  • the piston which is slidably accommodated in the pot part, serves to achieve a pumping stroke, with a return spring acting between a piston part connected to the piston and the pot base.
  • the piston part has a contact cover against which the return spring rests, which is supported on the pot base, and together with the pot part forms a first interior space, the volume of which changes when the pump is actuated, with the first interior space also being surrounded by a second interior space which is formed between the head piece, the pot part and the piston part.
  • the proposed air path can prevent an air cushion that may form between the pot part and the piston part when the dispenser pump is activated, particularly when the pump chamber volume is reduced.
  • the resulting pressure build-up would lead to an increase in the actuation force for moving the head piece in addition to the restoring force of the restoring device.
  • This problem is avoided by the air path provided.
  • the interior space that forms between the pot part and the piston part is exposed to the ambient air pressure via the air path, regardless of the position of the head piece relative to the dispenser pump.
  • the second interior space which surrounds the first interior space, is connected to the ambient air due to a gap that is usually present between the head piece and the pot part and is therefore under the same pressure. Air flowing from the first interior space into the second interior space during operation, in order to avoid excess pressure in the first interior space, can thus easily escape into the environment without a significant build-up of pressure in the second interior space.
  • the air path can be provided in a kind of bore in the upper end wall of the piston part.
  • the end wall outside of the structurally required areas for holding, for example, a piston part wall and a connection to the outlet channel can be almost completely open, so that a correspondingly enlarged air path is created.
  • the end wall of the piston part can also be designed like a spoke, for example in relation to a top view in which the longitudinal axis is shown as a point, with the air paths being formed between the spokes.
  • a dispenser 1 for arrangement on a storage container 2.
  • the storage container 2 is designed as a substantially cylindrical body with a central longitudinal axis x, which in the corresponding assignment position also passes through the dispenser 1, preferably in the form of a rotation axis.
  • the storage container 2 has a storage chamber 3 for receiving a mass M to be dispensed. This storage chamber 3 is limited at the bottom by a follow-up piston 4.
  • the dispenser 1 is inserted into the opening of the storage container 2, which opening points upwards when the storage container 2 is in its normal position, and is fastened to the storage container 2.
  • the dispenser 1 essentially consists of a head piece 5 and a dispenser pump 6.
  • the dispenser pump 6 initially has a piston body 7 with a piston 8 and a pot part 9 with a pot bottom 28 and a cylinder section 10.
  • the piston 8 is received in the cylinder section 10 so as to be slidable along the longitudinal axis x, a pump chamber 11 being formed between the piston 8 and the cylinder section 10 and further delimited by the pot bottom 28 of the pot part 9.
  • the pot part 9 is designed to be interchangeable in order to adapt to different storage containers 2, in particular different opening diameters and/or cross sections of the storage container 2.
  • the pump chamber 11 connects an inlet channel 12 and an outlet channel 13, wherein both channels can be separated from the pump chamber 11 by an inlet-side valve 14 and an outlet-side valve 15.
  • the two valves 14 and 15, which are designed as check valves, are preferably installed in such a way that they open in the same direction, i.e. in the dispensing direction.
  • a return device 16 here in the form of a cylinder spring, is arranged between the piston part 7 and the cylinder section 10.
  • This can usually be a metal cylinder spring.
  • a spring made of a suitably elastically resilient plastic material can also be provided here to create an all-plastic dispenser.
  • the return device 16 is further arranged such that it is supported at one end on the pot base 28 in a preferably concentric arrangement to the longitudinal axis x and at the other end acts against an upper end wall of the piston part 7, such that the head piece 5 with the piston part 7 and the piston 8 is acted upon in the direction of a pump chamber enlargement in order to refill the pump chamber 11 after a pump stroke has taken place, during which the pump chamber volume is reduced.
  • the piston part 7 and the pot part 9 are each essentially pot-shaped. They engage with each other and together limit the dispenser pump 6 outwards, so that a capsule-like housing is formed.
  • At least one fastening projection 28 can be provided on a radial pot wall 17 of the pot part 9, which can also be designed as a ring projection, for example. This fastening projection 18 serves to fix the position of the dispenser pump 6 in the installed state between the head piece 5 and the storage container 2.
  • valves 14 and 15 are designed as so-called annular gap valves with a ring-like valve body, which each covers an annular gap 19 or 20 of the inlet or outlet channel 12, 13.
  • the radially symmetrical design of the dispenser pump 6 results in homogeneous dispensing behavior.
  • the dispenser pump is not limited to radially symmetrical designs, but can also have any cross-section, for example square or polygonal.
  • other known check valves for example flap valves, can also be used.
  • piston 8 can be formed in one piece with the piston part 7.
  • a kinematic reversal of the dispenser pump 6 with a reversal of the opening direction of the check valves is also possible.
  • the head piece 5 is connected to the dispenser pump 3 and has a dome-like actuating part 21 with a dispensing channel 22 and a dispensing mouth 23, as well as an actuating surface 24 formed on the upper side, preferably transversely to the longitudinal axis x, and an actuating part wall 25 which may be concentric with the longitudinal axis x.
  • the actuating part 21 is guided, preferably circumferentially on the outside of the wall, via its actuating part wall 25 through the pot wall 17 of the pot part 9 in the axial direction.
  • the dispensing channel 22 which in the illustrated embodiment initially receives the longitudinal axis x in the middle of its longitudinal extension, is with reference to a cross-sectional view in which the longitudinal axis x is shown as a line, for example according to Figure 1 with a preferably obtuse angle to the longitudinal axis x and opens into the dispensing outlet 23.
  • the dispensing channel 22 is inserted in a sealing manner into the outlet channel 13, whereby in the use position the piston 8, the piston part 7 and the dispensing channel 22 together with the actuating part 21 cooperate for joint movement along the longitudinal axis x. Accordingly, the entire head piece 5 with the piston 8 fixed to it is supported via the return device 16.
  • the dispenser pump 6 or the dispenser 1 as a whole When the dispenser pump 6 or the dispenser 1 as a whole is inserted into the storage container 2, a lower edge 28 of the dispenser pump 6 with its inlet channel 12 dips so deeply into the storage container 2 and thus into the mass M stored there that there is direct contact with the mass M to be dispensed.
  • the dispenser 1 When the dispenser 1 is placed on the storage container 2, the mass M can thus spread out into the pump chamber 11 for the first filling thereof, preferably through the inlet valve 14 which opens during the exposure to pressure.
  • the dispenser 1, in particular the head piece 5, can be covered by a cap 26 in the non-use position. In this case, this is in the area of the pot wall 17, optionally, as further preferred, with axial support on the fastening projection 18.
  • a limiting device 27 is provided to limit the axial displacement of the head piece 5 together with the piston 8, in particular in a position at a distance from the pot part 9. This limiting position shown is the position of maximum filling of the pump chamber 11.
  • the dispenser pump 6 is fixed to the storage container 2 by a locking connection 30. This is provided in an area substantially directly below the fastening projection 18 of the pot part 9, which is supported on the wall of the storage container 2.
  • two locking beads 31, 32 are provided which are spaced apart from one another with respect to the longitudinal axis x and which each project radially outward beyond an otherwise given circumferential outer surface 33 of the pot wall 17.
  • the outer surface 33 of this pot wall 17 rests against the facing inner surface 34 of the chamber wall 35 in the locking position.
  • the two locking beads 31, 32 are in the illustrated embodiment with respect to a cross section according to the illustration in Figure 2 designed the same.
  • each locking bead 31, 32 is initially provided with an acute angle ⁇ with a
  • the leg 36 is provided with an axis parallel y of approximately 30 to 45 degrees to the longitudinal axis x and extends radially outward in a direction opposite to the insertion direction r.
  • This leg 36 merges at the end into an insertion curve 37, which in turn runs into a contact surface 38 which, with respect to the longitudinal axis x, runs approximately at right angles to the axis in the longitudinal cross section.
  • the contact surface 38 is accordingly directed opposite and transverse to the insertion direction r.
  • a height a of each locking bead 31, 32 results, which can correspond to approximately 1/3 to 2/3, for example approximately 1/2 of the material thickness of the chamber wall 35.
  • the height dimension a is measured between the root areas of the locking beads 31, 32, in which they run into the outer surface 33 of the pot part 9 (compare Figure 2 ).
  • the distance b between the locking beads 31, 32, also considered in the direction of extension of the longitudinal axis x, can correspond to approximately 1.5 to 3 times, further approximately 2 times the locking bead height a.
  • the radial extension c considered transversely to the height a, which in the locking position corresponds to the entry dimension of the locking beads 31, 32 into the chamber wall 35, can correspond to approximately 0.3 to 0.8 times, furthermore approximately 0.5 times the bead height a.
  • the locking beads 31, 32 are in the locking position according to Figure 2 in correspondingly arranged and cross-sectionally adapted locking grooves 39 of the chamber wall 35. These locking grooves open accordingly towards the inner surface 34 of the chamber wall 35, whereby to reinforce the locking position, the contact surfaces 38 of the locking beads 31, 32 are assigned correspondingly aligned counter-contact surfaces 41 that completely cover them.
  • the locking beads 31, 32 are in a rear grip position with respect to the counter contact surfaces 41 of the locking grooves 39, 40.
  • the locking position can be found in a favorable manner.
  • the free upper edge of the chamber wall 35 as well as the locking groove 49 initially provided in the insertion direction r are overrun in a favorable manner.
  • the legs 36 and the lead-in rounding 37 support this effect.
  • a withdrawal of the dispenser pump 6 from the locking position against the insertion direction r is prevented by the possible full-surface contact of the contact surfaces 38 on the counter-contact surfaces 41.
  • a first interior space 43 is formed between the cylinder section 10 of the pot part 9 and a piston part wall 42 comprising this cylinder section 10 and the reset device 16.
