Definitions

  • the invention relates to a socket for cylindrical containers of the type mentioned in the preamble of claim 1.
  • Plug-in bases of this type are known, for example, from the publications US Pat. No. 2,918,188 A1 and US Pat. No. 3,028,702 A1. These known plug-in bases serve to improve the stability of the cylindrical or at least essentially cylindrical containers inserted or plugged into them.
  • the plug-in base known from the publication US Pat. No. 2,918,188 A1 has radially exciting and essentially axially extending spring elements which enclose and hold the inserted cylindrical container. If the springs become fatigued or permanently deformed, a reliable mounting of the cylindrical container in the plug-in base can no longer be guaranteed.
  • a bottle coaster or drip catcher in the manner of a plug-in base is known from the document FR 908 049 A1.
  • this plug-in base does not serve to hold the cylindrical container, namely to improve the stability of the bottle inserted into the plug-in base, but merely fulfills the task of holding itself at the bottom of the bottle.
  • plug-in base known from this document is constructed analogously to the plug-in base known from US Pat. No. 3,028,702 and has essentially the same disadvantages as this.
  • the invention has for its object to provide a plug-in base for cylindrical containers to improve the stability of these containers, which has a long service life even with very frequent insertion and removal of the cylindrical container, which then also secure the cylindrical containers Stability gives, if they are only inserted into the socket with a fraction of their total height and which nevertheless allows the cylindrical container to be inserted with relatively low insertion forces, thus only radially loads the inserted cylindrical container to a relatively small extent, even if the inserted cylindrical one Container does not exactly have a predetermined nominal diameter, but in individual cases has a diameter that lies within a quite large tolerance range for the nominal diameter or nominal diameter.
  • the basic idea of the invention lies in a combination of standing substantially radially and axially extending guide - rip or F EADERSHIP laminate with axially extending and radially exciting clamping springs. Thanks to the synergistic effect of both mounting and guiding elements, a permanent, firm stand can be guaranteed even for high cylindrical containers despite low insertion forces.
  • the spring bars arranged in the interior of the plug-in base ensure that the lower part of the cylindrical container is held securely against axial displacement.
  • the female connectors absorb or compensate for small fluctuations in the outer diameter of the cylinder vessel.
  • the cylindrical containers used in the plug-in base can be pulled out of the plug-in base without difficulty, despite the secure mounting, without spilling any liquid in the container.
  • the cylindrical containers to be inserted into the plug-in base can very often be replaced without the stable holder and the secure, precisely fitting guidance of the container in the plug-in base being impaired.
  • the plug-in base consists of a base plate which is connected in one piece or detachably to a cylindrical, open-ended socket. At least two female connectors are arranged in the interior of the socket, parallel to the inner wall of the socket, which hold the vessel to be inserted in the base steadily and serve to insert the vessel into the base.
  • the inner wall of the socket is preferably equipped with 2 or 5 female connectors. However, it is also possible to arrange 4 and more than 5 female connectors inside the socket.
  • the female connectors are preferably L-shaped and fastened in one piece with the short leg at the upper end of the connecting piece, while the lower end of the female connector is resiliently movable inwards and outwards.
  • the web which connects the upper edge of the female connector with the upper edge of the socket, is solid and dimensionally stable.
  • a thin stiffening web is arranged between the upper part of the female connector and the inner wall of the connector, which supports the pretensioning of the lower part of the female connector.
  • This stiffening bar also serves as a shape stability of the upper part of the female connector. Another advantage of this stiffening web is that it prevents the spring bar from breaking off when the cylindrical container is inserted if the spring bar is relatively thin.
  • the female connector preferably extends over the entire height of the connecting piece, the lower part of the female connector preferably projecting into an opening in the base plate.
  • the lower part of the female connector is thus resiliently displaceable inwards and outwards in the opening of the base plate.
  • the opening in the base plate extends from the inner wall of the socket to the inner part of the base plate.
  • the openings in the base plate also serve to clean the plug-in base when liquid flows out over the edge of the cylindrical container used and thus reaches the inside of the socket.
  • the plug-in base according to the invention can thus be easily cleaned by rinsing or rinsing.
  • the surface of the female connector directed into the interior of the base is preferably equipped with a bulge that corresponds to the curvature of the surface of the cylindrical container inserted into the base. This guarantees particularly good guidance and stable mounting of the cylindrical container.
  • the dimensions of the female connector depend on the size of the respective socket; i.e. The larger the cylindrical container to be used, the wider the spring slats are designed to guarantee a secure, stable mounting.
  • the respective female connector With a plug-in base for a glass cylinder with a volume of 100 ml, the respective female connector is about 4 to 8, in particular 6 mm wide and extends over the entire height of the socket.
  • the female connectors are preferably arranged on the inner wall of the socket so that the lower part is directed slightly inwards relative to the upper part of the female connector.
  • the edge of the female connector facing the inside of the socket is slightly shifted inwards relative to the vertical, i.e. that the lower part of the female connector is further inwards than the upper one.
  • the female connector is preferably under an inward bias. This bias is ensured by the connecting web between the female connector and the upper edge of the connector. So that the connecting web does not relax too early due to the constant or repeated replacement of the cylindrical containers, e.g. between the inner wall of the upper edge of the socket and the female connector, a stiffening web, which extends downwards in a wedge shape, is arranged.
  • the wedge-shaped stiffening web is preferably arranged at the upper end of the connecting piece for manufacturing reasons. In addition, the greatest flexibility of the female connector is achieved by this arrangement.
  • the cone-shaped inward bias of the female connector is primarily used to hold cylindrical containers stable, in which the diameter is at the lower tolerance limit, or the dimensional inaccuracies in the circumferential line.
  • the socket of the plug-in base is equipped with a continuous slot.
  • This slot has e.g. the advantage that you can observe the part of the cylindrical container from the outside, which is inserted into the socket of the socket. This is e.g. then of advantage if the container used is a measuring cylinder, in which the lower dimension may be hidden by the nozzle.
  • the connection piece can also be perforated with openings of any design, arranged one above the other, which enable observation of the lower part of the cylindrical container.
  • the plug-in socket is equipped with additional guide ribs in addition to the female connectors, which are also arranged on the inner wall of the socket.
  • the number of guide ribs is arbitrary.
  • the nozzle is preferably equipped with at least 2 or 3 guide ribs. More than 3 guide ribs can also be provided if this proves to be particularly advantageous in special cases.
  • the guide ribs are narrow but torsionally rigid. They preferably extend over the entire length of the socket in a vertical arrangement, the distance from the inner wall being at most as large as the distance between the uppermost edge of the female connector and the inner wall of the socket.
  • the guide ribs primarily take over the guidance of the cylindrical containers, and in particular the containers whose diameter is in the upper tolerance range.
  • the guide ribs ensure that the containers, which are resiliently held by the spring strips at some points on the circumference, are additionally guided and held so that the containers do not wobble.
  • the additional guide ribs are particularly advantageous if only a few female connectors are arranged on the inner wall of the connecting piece.
  • a particularly advantageous and stable mounting of the cylindrical container in the socket is achieved in a socket with 3 female connectors and 3 guide ribs arranged in between.
  • the guide ribs can also be arranged as circular sections on the inner wall of the connecting piece between the spring strips, a circular guide rib already being sufficient.
  • the vertical arrangement of the guide ribs is preferred over the circular arrangement.
  • the female connector is preferably integrally connected to the upper edge of the socket.
  • the female connector can also consist of two ribs arranged next to one another, which are connected in a dimensionally stable manner to the upper edge of the connecting piece via a common web.
  • the surface of the female connector facing the outer wall of the cylindrical container can be smooth, corrugated or equipped with knobs. It is only important that a slip-free mounting of the lower part of the cylindrical container is ensured via the female connectors and, if necessary, the additionally arranged guide ribs.
  • the base plate of the plug-in base according to the invention is circular, oval or angular and is connected in one piece or detachably to the cylindrical, open-ended socket. For certain applications, it is advantageous to clip, insert or screw the connector into the base plate. In this way, plug-in bases with different heights can be produced in a particularly simple manner and particularly cheaply.
  • the height of the nozzle depends on the size or the height of the cylindrical container inserted into the plug-in base.
  • the height of the base is approximately 10 to 40 mm, in particular 10 to 25 mm.
  • the height of the socket of the plug-in base is preferably approximately 25 mm.
  • the plug-in bases according to the invention are in particular for holding cylindrical containers, in particular in the laboratory glasses with a volume of 5 to 2000 ml are suitable, whereby a separate plug-in base is generally provided for each volume unit.
  • an insertion base is used for two cylindrical containers with different volume units.
  • the cylindrical vessel to be inserted into the base is equipped with the same outside diameter, but is of different heights.
  • the plug-in bases according to the invention are particularly suitable for cylindrical laboratory glasses with 5 10, 25, 50, 100, 250, 500, 1000 and 2000 ml.
  • the plug-in bases according to the invention can be made from any materials, as long as the materials have a corresponding dimensional stability and the female connectors are resiliently movable.
  • the preferred material is plastic, e.g. Polypropylene, polyethylene, polystyrene, polyamide and copolymers using polypropylene, polyethylene, polystyrene, polyamide.
  • plastics and materials can also be used if the shape stability and rigidity of the material is guaranteed.
  • the plug-in base has a base plate 1 which is connected to a cylindrical connecting piece 2.
  • the base plate 1 can be designed in a wide variety of shapes, for example hexagonal, round, oval, etc.
  • the base plate. of the plug-in base according to Figure 1 is equipped with support knobs 3, which guarantee a firm and secure support of the plug-in base, even if the base is not completely flat.
  • the cylindrical nozzle 2 is open at the top and smaller in diameter size than the B o-denplatte.
  • spring strips 4 are arranged, which are connected via connecting webs 5 to the upper edge of the cylindrical connector.
  • the connecting web 5 is designed so firmly that the female connector 4 is directed slightly inwards with a prestress, so that the inner edge of the female connector tapers conically downwards inwards.
  • a wedge-shaped stiffening web 6 is arranged on the upper edge, which supports the pretensioning of the female connector.
  • the base plate 1 is equipped with openings 7 inside the cylindrical socket, into which the ends of the female strips protrude in the event that the female strips extend over the entire length of the inner wall of the socket, i.e. from the top to the bottom plate. It is also possible to make the female connectors a little shorter, the end of the female connector not being in contact with the base plate.
  • the recesses 7 in the base plate extend from the inner wall of the cylindrical connecting piece 2 so far inwards that the spring strip extending into the recess 7 can move resiliently inwards and outwards in this recess.
  • the inner wall of the cylindrical connecting piece 2 has guide ribs 8, which are preferably arranged between the spring strips 4.
  • the guide ribs 8 are parallel and perpendicular to the inner wall arranges.
  • the inward edge of the guide rib is not conical inward.
  • the cylindrical connection piece 2 can be equipped with a vertical, continuous opening 9, as shown in FIG. If the stability of the material permits, the cylindrical connection piece 2 can also be equipped with several such openings.
  • FIG. 4 shows the perspective view of the plug-in base with three guide ribs 8 and three female connectors 5.
  • a measuring cylinder 10 is inserted into the plug-in base, which in the present case is designed so that the outer surface of the measuring cylinder has both the outer edge of the guide ribs and the outer edge touches the female connector 4.
  • FIG. 4 clearly shows that the female connector is arranged parallel to the inner wall of the cylindrical connecting piece in this case, since the outer surface of the cylindrical container presses the lower part of the female connector under prestress outwards.
  • the plug-in base shown in FIG. 4 with three female connectors and three guide ribs is only a preferred embodiment.
  • the inner wall of the cylindrical connector 2 can also be equipped with more than two or three female connectors and / or guide ribs.
  • the inner edge of the female connector is preferably curved so that the cylindrical containers are better guided and held with a larger contact surface.
  • the inner edge of the female connector is marked with 11.
