Definitions

  • the invention relates to a filter dispenser for receiving and releasing individual flat Filter cuts that are available in a variety in the filter dispenser.
  • Filter dispensers are used in laboratories, preferably in biotechnology, medicine, Pharmaceutical, food and beverage industry and environmental analysis used especially for filtration tasks under sterile conditions, such as microbiological and analytical work.
  • Filter dispensers are known.
  • DE-OS 31 28 547 A1 describes a filter dispenser for sterilized, disposable items of flat dimensions that can be used in medicine and in the laboratory. It is characterized by a magazine for holding a spiral-shaped or leporello-shaped, tubular, two-part band, which divides the disposable items, such as filters or nutrient cardboard discs, into sections on the inside.
  • the exit of the magazine has at least one opening width which allows the band with the enclosed disposable articles to be passed through.
  • pairs of transport rollers are attached, each of which grips a section of the two opposite parts of the belt.
  • EP 0 585 145 B1 discloses a filter dispenser in which the sections of the two parts of an analog tubular band are wound up to separate and release the filters from two rolls, which are differentiated by a third party in terms of their step sizes and circulation speeds by means of control and regulating devices are driven.
  • a disadvantage of these filter dispensers is the large number of components that make up the Filter dispensers exist and their unfavorable arrangement, which means inserting a new one hose-like tape makes the operator unfriendly.
  • the invention is therefore based on the object of being user-friendly To create filter dispensers that consist of a smaller number and less expensive Components exist than is the case with filter dispensers of the prior art.
  • a filter dispenser which consists of a magazine with a slot-shaped outlet for a hose-like band and adjacent tabs for the passage of the band parts.
  • the hose-like band is formed from two parts which are joined together via continuous edge and cross connections which can be released under tension, forming pockets in which the filter cuts are located.
  • One end of the tape deposited in the magazine is passed through the slot-shaped magazine exit and spread into its upper and lower sub-tape.
  • the sub-tapes are guided through tabs adjacent to the magazine exit in such a way that when the tape parts are simultaneously pulled through the tabs, the connections of the tape in the area between the tabs and the magazine exit are released and the enclosed flat filter cuts are released for removal.
  • the slot-shaped outlet has an opening width that lies between the thickness of the band in the area of the pockets filled with the filter cuts and an additional dimension of up to about 1 cm, preferably the width of the cross connection between the band parts, ensures that when pulling the tape parts through the tabs, the tape can only be opened in the part that is outside the magazine, ie above the slot-shaped magazine exit. Since this state can be recognized manually, no further aids, such as stepping motors or sensors and the like, are required to open the band and expose the filter cuts for removal. In the simplest case, the band parts are pulled under the tabs by hand until the filter cut can be removed. The band below the slot-shaped magazine exit remains closed.
  • the magazine can consist, for example, of a folding box with a hinged lid with slot-shaped outlets located in the side surfaces or the edges.
  • the tabs can be made of the same material and are firmly connected to the magazine, for example glued on. Advantageously, they end approximately with the slot edge.
  • there is a rotatable roller for winding up one of the spread tape parts tension being exerted on the tape during the winding up and when the other tape part is pulled synchronously by a second tab in such a way that the connections of the tape in The area between the tabs and the magazine exit is released and the enclosed flat filter cuts are released for removal.
  • the connections of the band in the region between the tabs and the magazine outlet being released by tensile stress during winding and the enclosed flat filter cuts being released for removal. It is advantageous if the two rollers can be rotated in opposite directions and synchronously with one another.
  • the tubular band assembled from two parts can be produced from all band materials familiar to the person skilled in the art, which can be joined together in such a way that the connections can be loosened from one another under tension, for example from medical paper.
  • At least one part of the band advantageously consists of a film of an organic polymer.
  • the tapes are made so that the flat filter cuts in the pockets are sterile. So that a large number of filter cuts can be accommodated in the magazine of the filter dispenser, it is appropriate that the tubular band is rolled up in a spiral, laid in a leporello shape or folded.
  • the magazine is intended to accommodate a plurality of hose-like bands, with an outlet having an opening width permitting the band being provided for each band. This is useful when filter cuts of different sizes are used or different filter types are used, such as sterile porous filters for collecting microorganisms and sterile nutrient cardboard discs which are used to incubate the collected microorganisms.
  • the filter dispenser 1 consists of a magazine 2 in the form of a folding box.
  • the magazine 2 has a slot-shaped outlet 3, which is located in an edge of the folding box. Adjacent to the slot-shaped exit 3 are a first 4 and a second 5 tab, which end with the slot edges of the exit 3 .
  • the magazine takes up a hose-like band 6 , which is assembled from two parts 7 , 8 by continuous and releasable under tension edge (partially shown by hatching 9 ) and cross connections 10 to form pockets 12 receiving the filter cuts 11 .
  • the lower part 7 of the band 6 which consists for example of medical paper, is passed through the flap 4 and the upper part 8 of the band 6 , which consists for example of a polycarbonate film, is passed through the flap 5 .
  • the ends of the spread band are grasped and pulled through the tabs simultaneously and as evenly as possible.
  • the edge 9 and cross connections 10 of the band 6 are released when passing the slot-shaped magazine outlet 3 in the area between the tabs 4, 5 and the magazine outlet 3 and the enclosed filter cuts 11 are released for removal.
  • FIG. 2 shows the filter dispenser 1, in which a rotatable roller 13 , 14 is arranged after the tabs 4 and 5 for winding up the spread band parts 7 and 8 .
  • the roller 13 is equipped with a handle 15 for manual turning.
  • the roller 14 is connected to the roller 13 via a transmission. By rotating the roller 13 in the direction indicated by the arrow, the spread ends 7 , 8 are wound up, the filter cuts 11 being released for removal.
