Definitions

  • the present invention relates to a dispenser for pasty materials in particular according to the preamble of claim 1.
  • Dispensers for pasty masses in which the same amount of output should always be achieved by actuating a print head, are already known in numerous embodiments.
  • the force for dispensing the mass to be dispensed is generated exclusively by a hand-applied pressure force, so that no propellant gases are required to expel the mass.
  • the dispenser according to DE-OS 32 26 835 has a number of disadvantages.
  • the closure cap When the closure cap is lifted off, the dispensing channel is formed continuously from the dispensing mouth to the inside, so that in the open state there is the possibility that pasty masses which flow more easily by themselves, for example when the dispenser falls over can leak.
  • annular collar is provided in the dispenser according to DE-OS 32 26 835 on the closure cap, which is put over the dispensing channel and brought into sealing contact.
  • the sealing effect must be particularly good in order to generate the vacuum required to move the trailing piston when unscrewing the dispenser button inside the container. Since there are no other sealants between the discharge channel and the sealing collar, high dimensional accuracy must be maintained during production. However, it is not visible from the outside due to the structural design whether the appropriate sealing of the dispensing mouth of the dispensing channel is achieved.
  • position securing elements in the form of leaf springs with corresponding spring tongues are provided, which prevent the trailing piston from moving against the dispensing direction.
  • leaf spring tongues or leaf spring rings are made of appropriate steel in order to generate the necessary position securing.
  • the present invention is therefore based on the object of creating a dispenser for pasty masses in particular, in which a constant dispensing quantity is ensured and which can be recycled.
  • a valve is provided in the dispensing channel, which opens only in the dispensing direction, it is achieved that a secure sealing with a correspondingly constructive expenditure of the dispensing mouth is not required, which results in correspondingly low manufacturing costs. Furthermore, the dispenser is recyclable, which makes a corresponding contribution to environmental protection.
  • the check valve between the intermediate chamber and the dispenser housing ensures that the pressure applied via the dispenser button only acts on the mass located in the intermediate chamber, which also represents a clearly defined volume. Thus, no pressure is applied to the inside of the container.
  • the dispenser is advantageously formed from a single recyclable material, the dispenser can be completely shredded after use and the shredded material can be used again.
  • the volume of the dispenser is greatly reduced by just a few shredding steps, which means that smaller volumes are possible during transport.
  • the recyclable material is preferably polyolefin.
  • the dispenser in such a way that a cylinder insert connected to its housing is provided, which has an annular intermediate chamber, along which the dispenser button can be moved up and down, particularly good guidance of the dispenser button is achieved, which in turn entangles or jams at one prevents rapid pressing of the dispenser button.
  • a rotation limiting device between the cylinder insert and the dispenser button ensures that the dispenser button is not moved when the rotating element is moved, so that the dispenser button is reliably moved back into the starting position after the pasty mass has been dispensed from the dispenser.
  • the rotation limiting device is designed such that a projection is arranged in a longitudinal groove.
  • the closure cap of the dispenser can form the rotary element.
  • the rotary element can be designed as an axially fixed rotary ring through which the dispenser button extends.
  • the dispenser 1 and 2 show a first embodiment of a dispenser 1 according to the invention.
  • the dispenser 1 has a housing 3 and a dispenser head 5 which is designed as a dispenser button 7.
  • a trailing piston 13 is arranged in the housing 3 of the dispenser 1, which is sealingly fitted into the housing 3.
  • the housing 3 has an upper partition 15, so that there is space for the pasty mass between this and the trailing piston 13.
  • FIG 3 shows the initial position of the dispenser button 7 in the upper left half and the end position of the dispenser button 7 in the upper right half.
  • the dispenser head 5 has a cylinder insert 23 which forms a circular intermediate space 25.
  • a hollow piston 27 connected to the dispenser button 7, the central opening 29 of which is connected to the dispensing channel 19 via a valve 31.
  • annular projection 33 is provided with notches 35 which engage with corresponding notches 39 of an outer wall 37, the outer wall 37 being formed on the cylinder insert 23. Further inward is a circular intermediate wall 41 which, together with the outer wall 37, forms a slot 43 into which the projection 33 comes to rest.
  • a support wall 45 is also provided, which has a projection 49 provided with a nose 47, which is also of circular design.
  • the annular nose 47 serves as a stop for an annular nose 51, which is formed on the outer lower edge of the dispenser button. In the initial position in the left half of the picture, the two nose projections 47 and 51 are in engagement with one another.
  • the dispenser button 7 has an upper button area 53 which is provided with projecting curved ribs 54 in order to prevent the finger or fingers from slipping off when the dispenser button 7 is pressed.
  • a groove 59 formed by projections 58 which run in the longitudinal direction of the dispenser is provided on the inner wall 57 of the septa button 7, into which a groove 59 formed on the cylinder insert 23 is provided Protrusion 60 engages.
  • the dispenser button 7 is mounted in a rotationally fixed manner, since the cylinder insert 23 is itself connected to the housing 3 of the dispenser 1 in a rotationally fixed manner.
  • the dispenser button 7 has reached its end position, i.e. the piston 27 almost touches the upper partition 15 of the container 3 and the lower edge 52 of the dispenser button 7 is in abutment against a radial region 61 of the cylinder insert 23.
  • the dispenser button 7 has frusto-conical areas 63 and 64, which allow the closure cap 21 to be easily placed over the dispenser head.
  • the threaded pieces 11 come into engagement with corresponding threaded projections 12 which are formed on the inner wall of the closure cap 21, these also extending helically at an angle, so that by further turning due to the closure cap 21 striking the cylinder insert 23 the dispenser button 7 can be moved out of the end position again into the starting position according to the left half of FIG. 3.
  • the opening 9 of the dispenser button 7 seals in the end position on the cap 21.
  • the dispenser 101 has an essentially similar structure to the dispenser 1 according to FIGS. 1 to 4, but there are some essential differences.
  • a follower piston 113 is formed in a housing 103, which, together with an upper partition 115 of the container 103, forms a receiving space for the pasty product.
  • a check valve 117 is provided, which connects the interior of the container to an intermediate space 125, which in turn is connected to an outlet channel 119 via a valve 131.
  • a cylinder insert 123 is provided, which, similar to the dispenser 1, is connected to the upper partition wall 115 via an annular projection 133.
  • the dispenser button 107 is arranged to be movable in the longitudinal direction, being surrounded by a rotating ring 108.
  • the discharge mouth 109 of the discharge channel 119 is closed with a suitable plug 110 in this embodiment.
  • FIGS. 7 and 8 in which the trailing piston 113 is shown in its uppermost position, that is to say the dispenser 101 has been emptied, the various positions of the dispenser button 107 are illustrated.
  • the dispenser button 107 is in its starting position in the left half of the picture, while it is in its end position in the right half of the picture.
  • FIG. 8 shows a view from the left of FIG. 7, the dispenser button 107 being in a central position between the start position and the end position.
  • annular bead-like projection 122 and 124 which serve as a stop, whereby, as can clearly be seen from the left half of FIG bead-like protrusions 122 and 124 are engaged with each other to define the upper start position of the dispenser button 107.
  • the dispenser button 107 likewise has a projection 126 which comes into engagement with a shoulder 128 which is formed on the inside of the rotary ring 108.
  • a rotation locking device 130 is provided which prevents the dispenser button 107 from rotating relative to the cylinder insert 123.
  • the dispenser button 107 can be turned back to the starting position according to the left half of FIG. 7.
  • FIG. 9 also shows a curve with details of the rotation angle that has already been passed through.
  • the dispenser 1 or 101 according to the invention is only assembled from parts which do not have to generate any particular compressive or spring forces, so that they need not be made of metal.
  • This enables the entire donor to be made to produce a material, for example a polyolefin, so that a complete recycling possibility is created by fragmentation or comminution.
  • a very high percentage of the shredded granulate can also be reused for the production of new donors.
  • the dispenser 101 has a separate closure cap 140 which can be put over the dispenser head 105.
  • a dispenser can also be created in which the valves 17, 117 and 31, 131 are omitted and a piston with a locking spring is used. Such a dispenser is then used as a strip dispenser.
