Definitions
- the invention relates to a metering pen for dispensing flowable masses according to the preamble of claim 1.
- Flowable masses in particular those which are only flowable under pressure due to their viscosity or because of their pasty character, overcome an increased flow resistance in the capillary with the aid of a piston.
- Clearing order elements such as brushes, wick or sponge.
- the filling can only take place by means of a narrow cannula, since not the entire diameter of the storage container is available, as in the present invention.
- An embodiment variant provides that the nut provided for actuation is exposed laterally, but the disadvantage arises that when the piston is screwed in, the grip area of the nut becomes ever smaller and unwieldy. In the present invention, the operating area remains unchanged.
- the piston must be secured against rotation in order to transmit the propulsion. This is done in the present case in that the container wall receiving the piston is not round but octagonal. A reliable seal is not possible.
- the assembly is complex because the piston must first be screwed onto the threaded spindle.
- the invention is based on the object of supplying flowable masses from a storage container to an application element, the flow resistance occurring thereby being overcome.
- the operation should be handy and offer a reproducible measure for the dosage.
- the number of individual parts should be a minimum to fulfill the task and their design and arrangement should enable machine-appropriate assembly with little effort.
- the threaded rod is a symmetrical structure and is therefore easy to sort and assemble.
- the arrangement enables easy assembly and filling from one side, which makes the assembly devices simple. If the order element is changed, all other components remain unaffected.
- the actuating element can be reached and rotated by the operating fingers through side windows. Such an arrangement has the advantage that unintentional actuation and thus leakage is avoided when carried in clothes or bags.
- the movement thread of the actuating element is followed by a centering diameter, the length of which represents a multiple of the movement thread. This leads to an additional guidance of the threaded rod, which makes it particularly easy to move.
- this is provided with a toothing, as a result of which an axial and radial fixation in the storage container is achieved.
- the actuating element has, on the end facing the floor, radially arranged pawls which engage in corresponding counter pawls on the floor. It is thereby achieved that the reaction force of the piston expelling the mass creates a locking mechanism without additional parts, which prevents reset, on the other hand provides the user with an acoustic measure of the actuation path.
- a simple axial fixing of the actuating element is achieved on the one hand by the stop surface of the guide bush and on the other hand by the bottom of the storage container. (Fig.1)
- FIG. 2 Another embodiment of the axial fixing of the actuating element is shown in FIG. 2.
- the actuating element is located within the stop surface and the undercut of resilient segments.
- a guide bushing has already been described, which is secured against the storage container in such a way that a payment located on the guide bushing and on the storage container results in an axial and radial fixation.
- Another disadvantage is that the attachment of the teeth in the reservoir, a reinforcement of the wall in the region of the actuating element is necessary in order to be able to carry out a demolding in the injection molding process. This reduces the diameter of the actuating element and thus increases the actuating force to be applied. In addition, there is a greater depth for the access to the actuating element, which makes the actuation less user-friendly.
- a guide bushing is diametrically two has arranged segments which are separated by longitudinal slots and that the resilient end of the segments has a rotation stop which comes to rest radially on a web and a longitudinal stop which bears axially on a window edge.
- the mounting plunger on the end of the guide bush resiliently generates friction, so that when the actuating element is rotated, the guide bush is rotated until its segments can spring open in the web-free zone and come to rest radially on the web and axially on the window edge .
- the guide bush is fixed radially and axially, the radial stop corresponding to the direction of rotation of the actuating element, which moves the piston forward.
- FIG. 6 shows a longitudinal section through the metering pin with the actuating element protruding from the end of the container.
- FIG. 7 shows a cross section through the actuating element and threaded rod of FIG. 6
- FIG. 8 shows a partial longitudinal section and partial view of the guide bush with resilient segments.
- FIG. 9 shows a view of the guide bush of FIG. 8 in the axial direction.
- Fig. 10 partial longitudinal section of a modified
- Fig. 11 partial longitudinal section as above, after assembly and rotation of the guide bush.
- Fig. 14 View of the guide bush in the direction of the piston.
- a storage space 2 is provided, in which the flowable mass, not shown, is located.
- the actuating element 3 is rotatably mounted in the guide bush 4 and with its outer diameter 5 in the storage container 1.
- the actuating element 3 At the front end of the actuating element 3 there is the movement thread 6, to which the centering diameter 7 connects.
- the actuating element 3 is axially fixed within the stop surface 8 and the base 9. Molded inwards on the bottom 9, there are the radially arranged pawls 11, which correspond to the counter pawls 10 on the actuating element 3.
- the actuating element 3 can be reached and rotated through the windows 12.
- the flattened threaded rod 13 is screwed into the movement thread 6 and is additionally guided in the centering diameter 7.
- the threaded rod 13 protrudes through the passage 14, which corresponds to the contour of the threaded rod 13. This creates an anti-rotation device with simultaneous longitudinal movement of the threaded rod 13.
- the guide bush 4 has a toothing 15 which has its counterpart in the reservoir 1 and is used for the radial and longitudinal fixation of the guide bush 4.
- the threaded rod 13 is supported on the piston 15, which seals and transports the flowable mass located in the storage container 1.
- the mounting side 17 of the storage container 1 is closed by the fastening thread 18 with the application element 19.
- the latter can have a different design. In the present case, it is equipped with a brush 23. Execution Fig. 6 to 9
- the structure of the rotary metering pin according to FIGS. 5 to 9 represents a variant within the inventive concept.
- the actuating element 3 ' protrudes freely from the end of the storage container 1'.
- a storage container 1 with storage space 2 is shown in the area of an actuating element 3.1.
- a guide sleeve 4.1 which has four slots 4.2, adjoins this via a stop surface 8.
- the segments 4.4 form at their resilient end a twist stop 4.5, which comes to rest on a web 12.1, and a longitudinal stop 4.5, which rests on a window edge 12.2 (FIG. 11).
- the segments 4.3 have non-stop edges 4.7 at their resilient end.
- An outer diameter 5.1 of the actuating element 3.1 is rotatably mounted in the storage container 1.
- the actuating element 3.1 contains a movement thread 6, into which the threaded rod 13 is screwed. This leads on the one hand in the centering diameter 7, on the other hand in the passage 14 of the guide bush 4.1.
- the actuating element 3.1 lies in the installed state on the floor 9.1. (Fig.11).
- the storage container 1 has two opposite windows 12 on the side, which represent cutouts from the cylinder jacket of the storage container 1 and from which two webs 12.1 are retained.
- the actuating element 3.1 is axially fixed between the floor 9.1 and the stop surface 8. It is thereby achieved that on the one hand the reaction forces of the piston 16 are supported on the bottom 9.1, on the other hand the actuating element 3.1 cannot be inadvertently shifted to the piston side, thereby avoiding overdosing.
- the anti-rotation device is achieved in that when the actuating element 3.1 is rotated, the guide bushing 4.1 also rotates until the rotation stop 4.5 has reached the web 12.1.
- the friction which is required for the rotating entrainment of the guide bush 4.1, is generated in the stop surface 8 by means of the axial shaft of the assembly plunger, which rests resiliently on the guide bush 4.1.
- the segments 4.4 can only spring open if the guide bush 4.1 is rotated such that the longitudinal stops 4.6 reach the area of the window 12 or the window edge 12.2.
- the longitudinal movement of the threaded rod 13 is transferred to the piston 16, which in turn exerts pressure on the flowable mass located in the storage space 2.
- the capillary spaces of the application element 19 fill up, making it possible to dispense the flowable mass.
- the pawl 10 which is axially loaded during the rotation of the actuating element 3, snaps audibly. noticeable in the counter pawl 11 of the bottom 9. The effect of this locking mechanism gives the user a measure of the dispensed quantity. In addition, the pawl 10/11 prevents rotation against the conveying direction.
- the mode of operation of the dosing rotary pin according to FIG. 6 is the same as the aforementioned. In contrast to Fig. 1, operation is carried out using an exposed rotary knob. In addition, this version eliminates the pawl with the locking effect.
