Definitions

  • the present invention relates to a device for expressing a liquid and / or gelatinous and / or pasty substance from a deformable tube, comprising a push-out element with two opposite Ausdschreibschenkeln for gripping the tube to be expressed and pushing out the substance from the tube, and a housing for receiving the Ausdschreibelements.
  • Such ejection devices are known from the prior art. With the aid of these devices is a controlled release of substances from deformable tubes, that is, metal or plastic tubes, which can be compressed to allow the substance from a dispensing orifice.
  • a device which comprises a squeezing element, consisting of a pair of expressing arms connected to one another in a rotary joint for receiving the tube body, and a housing which contains this squeezing element.
  • DE 699 05 163 describes a device with a push-out element whose Ausd Wegschenkel are attached at one end to a support and connected by this. Furthermore, the said device comprises a housing having both an opening at a base end and at an upper end.
  • the Ausdschreibschenkel at a lower end are pivotally connected to each other or with a carrier.
  • the tube to be expressed When inserting a tube to be expressed into the ejection element, the tube to be expressed must be introduced from above, that is to say from the direction of the unconnected ends of the ejector legs into the ejection element.
  • the prior art ejectors have the disadvantage that the thickness of the tubes to be ejected is limited. Further, integrating the tubes and assembling the individual components is often not easy in the prior art ejectors.
  • the present invention has for its object to provide an alternative Ausd Wegvorraumsch available, which overcomes the disadvantages of the prior art.
  • One goal is to allow easy insertion of a tube to be expressed in the squeezing.
  • Another goal is, for example, to reduce the effort required to express.
  • a device for extruding a liquid and / or pasty and / or gelatinous substance from a deformable tube comprising a push-out element with two opposite Ausdschreibschenkeln for gripping the tube to be expressed and pushing out the substance from the tube and a housing for receiving the Ausdschreibelements, wherein the Ausdschreibschenkel the Ausdschreibelements at a lower, the opening of the tube to be expressed opposite end are free.
  • the device according to the invention can be used to deliver any substance be used with the behavior of a fluid, gel or pasty substance.
  • the device according to the invention is suitable for use in dispensing adhesives. It is not easy to dispense sticky substances or glue solely by manipulating a deformable tube containing it, since it is virtually impossible to apply a controlled amount of the substance to the exact point desired.
  • the Ausdschreibschenkel the Ausdschreibelements are held in the assembled state, at least in the region of the lower end by means of the housing in position.
  • This in-position holding of the Ausdschreibschenkel through the housing replaces a direct articulated connection of the two Ausdschreibschenkel, as is known in the prior art.
  • the holding of the Ausdschreibschenkel through the housing can be done for example by snap, snap or clamp connections. By these usually releasable connections can also be achieved that the entire Ausdschreibelement is held in the housing.
  • the Ausdschreibschenkel are arranged at least in a rest position in the form of a V, the Ausdschreibschenkel at the top of the V (lower end) are not, in particular not insoluble, interconnected.
  • the legs touch at the top of the V, but this does not mean that the legs are connected to each other.
  • the tip of the V is held together by the above-mentioned means of the housing. This point where the thighs at the top of the V held together by the housing usually functions as a hinge in compressing the legs.
  • the Ausdschreibschenkel in particular in the region of the lower end, on devices which cooperate with means of the housing to hold the Ausdschreibschenkel, in particular in the region of the lower end in position.
  • the facilities of Ausdschreibschenkel ribs and / or lugs and / or grooves.
  • the expressing element comprises actuators, in particular wings, which are connected to the ejector legs, preferably in an upper area, e.g. connected by webs, in particular film hinges, connected, preferably articulated.
  • actuators preferably act as levers, with a force exerted on the actuators being potentiated and transmitted via the ejector legs to the tube to be expressed.
  • webs ensure that the ejector legs are moved toward and simultaneously upwardly (in the direction of the tube opening) to slide under the tube shoulder to completely empty the tube. This arrangement significantly expands the force applied to the actuators.
  • the ejection element has in an upper region a holding device with an opening for receiving and holding the tube to be expressed.
  • This holding device is usually also hingedly connected to the above-mentioned actuators.
  • Such a hinged connection is preferably achieved via thin, flexible connecting strips, which connect the holding device with the actuators.
  • the housing may be integrally formed. In particular, however, due to a simpler manufacturability, it is preferred that the housing is formed in two pieces. Overall, the device according to the invention is preferably formed in three pieces, wherein the Ausdrückelement preferably in one piece and the housing is preferably formed in two pieces.
  • the device according to the invention is usually made of plastic.
  • the device according to the invention is produced by injection molding. This allows a simple and inexpensive production.
  • housing elements are integrated in the ejection element. This embodiment will be explained in more detail below (figure description).
  • FIG. 1 Fig. 3 illustrates an exploded view of a squeezing device 1 according to the invention as it would be assembled for use.
  • Device 1 comprises a squeezing element 2 and a housing 3, wherein the housing 3 is composed of a first housing part 4 and a second housing part 5.
  • the ejection element 2 has two opposite Ausdschreibschenkel 6a, 6b for gripping a tube to be expressed and pushing the substance out of the tube. In the present representation, no tube has yet been integrated into the ejection element 2.
  • Expressing element 2 also has oppositely arranged squeezing wings 7a, 7b, which are connected via webs 8a, 8b hingedly connected to the Ausdschreibschenkeln 6a and 6b.
  • the webs 8a, 8b ensure that the squeezing legs 6a, 6b are moved towards and towards the top at the same time (in the direction of the tube opening) in order to push under the tube shoulder for complete emptying of the tube.
  • the ejection element 2 further comprises a holding region 9.
  • the holding region 9 is pivotally connected to the squeezing wings 7a, 7b. Further, the holding portion 9 has an opening 11 through which a nozzle 10 extends in the present case. This nozzle 10 has, not shown here, thread for receiving a discharge opening of a tube.
  • the housing 3 consists of a first housing part 4 and a second housing part 5. Both housing parts have mutually engaging structures in order to hold the two housing parts 4 and 5 together.
  • the housing part 5 ribs for receiving in corresponding grooves in the housing part 4.
  • the housing part 4 has ribs 13. These ribs 13 hold the V-shaped arranged Ausdschreibschenkel 6a and 6b in the assembled state together. By this clamping of the Ausdschreibschenkel 6a and 6b by the ribs 13 is achieved that the Ausdschreibschenkel 6a, 6b are held in a V-shaped position.
  • the procedure is as follows. First, a tube to be expressed with the opening in front from below, that is, from the top of the V, between the Ausdschreibschenkel 6 a and 6 b pushed, which are previously pressed apart. The tube is then inserted with the opening first through the opening 11 in the holding area 9 to the stop and screwed to the nozzle 10. Now, the expression is pushed with the tube integrated therein in the first housing part 4 until the Ausdschreibschenkel 6a and 6b engage with the ribs 13 and clamped. Finally, the second housing part 5 is pushed over the first housing part 4 such that the ribs 12 in the housing part 5 are in engagement with the grooves in the housing part 4.
  • the Ausdschreibschenkel 25a, 25b are arranged in a V-shape, wherein the Ausdschreibschenkel 25a and 25b are not connected to each other at the top of the V.
  • the Ausdschreibschenkel 25a, 25b press apart in this area, that is, move away from each other to accommodate the expressing tube 29 between the legs 25a and 25b can.
  • ribs 31 are provided in the lower region of the Ausdschreibschenkel 25a, 25b, that is at the top of the V.
  • the ribs 31 are arranged to cooperate with ribs 32 in the housing 22 by the ribs 32 of the housing 22, which are arranged one above the other, clamp the Ausdschreibschenkel 25 a, 25 b in the region of the ribs 31 between them and hold in position. This ensures that the V of the legs 25a, 25b can only be opened or closed upwards.
  • At the top of the V is formed by the clamping together by the ribs 32 in the housing a joint.
  • the squeezing wings 26a, 26b are arranged in the upper region of the tube 29 to be expressed. This is the area where the tube is most developed, so most of the effort is needed at that point.
  • the webs 27a, 27b cause the squeezing legs 25a, 25b to move towards and towards the top of each other (towards the tube opening) to push under the tube shoulder to completely empty the tube.
  • the housing parts 43 and 44 have superimposed ribs 49, which serve to clamp the Ausschschenkel 45a, 45b in the lower region (top of the V).
  • the Ausdschreibschenkel 45 a, 45 b at its lower end curved elements 50 a, 50 b, which are integrally connected thereto, on.
  • the bent elements 50a, 50b are clamped in the assembly of the device 40 between the ribs 49, which in turn the Ausdschreibschenkel 45a, 45b are held in position in the lower region.
  • the housing parts 43 and 44 have pins 51 and ribs 52 for insertion into channels 53 or grooves 54 in the ejection element 41. By means of said elements, a simple plugging together of the parts is possible.
  • the housing parts 43 and 44 are formed identically, which simplifies the manufacture of the entire device.
  • FIG. 3A shows a side view of the Ausdschreibelements 41 FIG. 3 ,
  • the V-shaped arranged Ausdschreibschenkel 45a and 45b are clearly visible.
  • the legs 45a and 45b in the lower region, that is, at the top of the V are not connected to each other. However, in this area, the legs of this embodiment transition into bent portions 50a, 50b. These bent portions 50a and 50b progress in turn into upwardly extending housing forming portions 55a and 55b.
  • These housing forming members 55a and 55b are largely loaded with reinforcements 56a, 56b.
  • the squeezing wings 46a, 46b are arranged overlying.
  • the staggered arrangement of the upper portions of the housing forming members 55a, 55b prevents the wings 46a, 46b from colliding prematurely with the housing forming members upon compression.
  • the ejection wings 46a and 46b are also connected in this embodiment via connecting webs 57 with the Ausdschreibschenkeln 45a, 45b, wherein the connecting webs 57 act as hinges.
