Definitions

  • the invention relates to a refilling device for laboratory containers, which makes it possible to quickly, safely and without spilling the substance from a first to a second container to fill a powdery substance. It is especially intended for applications in the context of Pulverdosier confusen, which have a dosing, which is fed by a working container.
  • the working container can be designed as a container that can be connected to the dosing head or firmly connected to it, or as a hollow space in the interior of the dosing head itself.
  • the substance supply is used up in the working container, it must be replenished, wherein substance is transferred from a reservoir into the working container.
  • This transfer of substance from a first to a second container is a relatively common process in some laboratories and can be done by simply shaking when the vessel to be filled has a sufficiently large opening and / or accidental spillage of substance can be accepted ,
  • Another difficulty also occurs when transferring substances that react with the ambient atmosphere or have a very high readiness for moisture absorption. This problem could be solved by filling the substance in a so-called glove box under a protective gas atmosphere, which is cumbersome and time consuming.
  • Coupling devices with shut-off valves have long been known in the art. They are used in particular, where after a Umglallvorgang should be prevented that the recirculated fluid exits the separate coupling parts.
  • a coupling device with shut-off valves is in the US Pat. No. 1,827,286 A disclosed. It is a coupling unit for railway cars and locomotives. Each of the coupling halves has an individually operable ball valve, which can be closed as needed before disconnecting the coupling halves, so that after disconnection of the coupling the gas pressure in the lines is maintained and the brakes are not blocked.
  • the present invention therefore has for its object to provide a container for refilling laboratory containers, which makes it possible to quickly and safely refill a particular powdered substance from a first to a second container, wherein the substance transfer from the first into the second container is substantially under tight closure so that no substance particles can escape to the outside during the transfer process and after the transfer process, or, if possible, no mixing of the gaseous medium present in the containers with the ambient air can take place.
  • a transfer device comprises a housing, which is either fixed or connected by a coupling means, with a reservoir.
  • the coupling means may for example be a threaded connection, a snap connection but also a simple plug connection.
  • the housing of the transfer device has a passage opening and a closure member movably connected to the housing for closing the passage opening.
  • the closure member has at least one connection point for at least one working container and is rotatable or slidable relative to the housing between at least one open position and at least one closed position. In the closed position, the passage opening is closed by the closure part, and in the open position, the interior of the reservoir is connected via the passage opening with the interior of the working container used in the at least one connection point.
  • the transfer device is suitable for connecting containers in order, in particular, to transfer a powdery substance from a first container, hereinafter referred to as a reservoir, into a second container, hereinafter referred to as a working container. Because the working container can be connected directly to the closure part, the opening of the working container can be guided past the passage opening directly. As a result, no, a dead volume forming, separable connection shafts are necessary, the separation of which there is a risk that substance can enter the environment.
  • the transfer device makes it possible for a reservoir mouth which is closed before the substance transfer to be opened and also closed again while the container mouths are coupled together are.
  • the Umyogllvorgang designed, for example, so that the working container to be filled is coupled with a closed by the Umyogllvortechnik reservoir, which is arranged with its mouth down in a holder.
  • the passage opening is opened by moving or pivoting the closure part, so that substance from the reservoir can flow into the working container to be filled.
  • the substance can pass from the reservoir into the working container, at the same time the gas volume present in the working container is displaced by the inflowing substance and flows as a result of the generated by the effluent substance negative pressure in the reservoir into the reservoir. Any dust development outside the inventive transfer device is thus avoided.
  • the closure part is closed again and the working container is released from the connection point and closed.
  • the possibility provided by the invention to keep a reservoir closed, as long as the container mouths are not coupled, also has the advantage that the contents of such a closed reservoir of each even short-term contact with the ambient atmosphere is completed, creating, for example, a moisture absorption or oxidation the substance contained in the container can be prevented.
  • the inventive refilling device can be designed so that the closure part is opened and closed by actuation of the outside, for example by an operator.
  • at least the working container to be filled consists of a transparent material, so that the operator can observe the material transfer and control it by adjusting the closure part.
  • sealing ring coaxial with the passage opening, which is in constant contact with the closure part.
  • further sealing elements for example a bellows, can be arranged between the closure part and the housing.
  • possibilities of positive locking for securing the connections of the transfer device are provided with the reservoir and the working container.
  • the connection of the working container inserted in the at least one connection point can be secured inextricably when the closure part is in the open position.
  • the closure member may be locked with a closure member lock in the closed position when no working container is connected to the at least one connection point.
  • An embodiment of the transfer device according to the invention with a plurality of connection points formed on the closure part is suitable for applications where a plurality of working containers with the same substance are to be filled from a storage container.
  • the angle of rotation or the displacement distance of the closure part can only be released by the closure part locking to the extent that connection points are equipped with working containers without any gaps, thus preventing the escape of substance through unoccupied connection points.
  • a coupling agent locking may be provided to prevent accidental opening of the reservoir.
  • the coupling means for connecting the transfer device with a storage container and also the connection point for connection to a working container can be designed, for example, as a screw connection, bayonet connection, latching device or insertion device.
  • the coupling agent and the connection point can be distinguished from one another without being confused, so that the coupling agent can only be connected to a storage container and the connection point can only be connected to a working container.
  • the transfer device and the storage container and working container to be connected to it are standardized in such a way that storage containers can be connected directly to the coupling means and working container directly to the connection point.
  • appropriate adapter can be created for storage and working containers that do not meet this standard connection.
  • these adapters preferably remain on the containers and not on the transfer device.
  • the different containers are provided with a standardized interface, by means of which these different containers can also be easily connected to a device with the same standardized interface, for example a dosing device.
  • a refillable chamber for a drying agent or a connection point to a replaceable desiccant cartridge can be formed, wherein the desiccant atmospherically communicates with the interior of the reservoir and optionally absorbs moisture from the substance in the reservoir.
  • At least one gas connection can be arranged on the housing of the transfer device, through which, for example, a protective gas can be supplied.
  • a protective gas can be supplied.
  • this can also be replaced by a gaseous medium present in the storage container or working container.
  • This can have several advantages. For example, can be changed by the supply of a corresponding gas, the flowability of the substance or even the reactivity of the substance can be influenced.
  • the arrangement of multiple gas connections is possible, which are connected to individual areas of the present transfer device and / or with the reservoir and / or with the working container.
  • a closure sealing device and / or a closure device is arranged on the housing of Umphilllvorraum, which serves for applying a lid, sealing plug and / or a sealing adhesive on the filling opening of the working container when the same solved after filling of the connection point becomes.
  • the at least one connection point can have a spring element, by means of which spring element a working container inserted into the connection point can be tensioned against the housing.

  • the connection point 5 and thus the mouth of the working container 6 is offset from the passage opening 10, so that the passage opening 10 is closed by the closure part 7.
  • the design the closure member 7 as a manually movable slider is particularly advantageous in connection with a working container 6 made of transparent material, since the progressive filling of the working container 6 can be observed and controlled and stopped by moving the closure member 7. So that no substance particles can enter the environment, the transfer device 1 has two sealing systems.
  • the first sealing system is arranged coaxially to the passage opening 10, annularly formed sealing ring 9. This sealing ring 9 seals the one hand, the better recognizability because of in the FIG. 1 To large game shown between the housing 2 and the closure member 7 from.
