Benefits of technology

[0007]The object of the invention is to provide an adapter device and a method which makes it possible to remove a specific quantity of a substance present in a container without endangering the user and without contaminating the environment.
[0015]This intrusion can furthermore serve as a lock which functions in such a manner that some of the substances is drawn into the intrusion and the intrusion is tied off twice at an arbitrary location and then is separated between the tie-off locations, the substance can be removed free from contamination and without endangering the user.
[0016]In addition, the main body can have an extended section into which the container is partially or completely emptied, wherein these removed quantities of the substance can again be separated from the container by tying off twice and separating between the tie-off locations free from contamination and without endangering the user.

Problems solved by technology

For some years, a number of materials have been in use which pose a high risk of contamination to the environment when they come in contact with it or to the persons working with them, and which must have a specific degree of purity for their usage or reprocessing.
Disadvantages of these technologies are that the ventilation cabinets or isolators must be cleaned when a substance is of a different type to the previous one, whereby costs are incurred and that a ventilation cabinet or isolator must be erected at each site at which substances in containers are to be checked or removed.

first embodiment

[0035]FIG. 1 shows the present invention wherein the adapter device comprises a base body 5 having an open section, intrusions 3 and at least one intrusion 4. In FIG. 1, the adapter device is not yet connected to a container 1 which contains another container 2.

[0036]With reference to FIG. 2, the base body 5 is fastened via its open section to the container 1 by means of a fastening apparatus 8, preferably an O-ring. Via the intrusions 3, the user can open the closure of the container 2, as shown in FIG. 3. Should the container I not contain another container 2, the adapter device can likewise be used. In this case, the closure of the container 1 must only be removed after fastening the adapter device and after removing the sample, and must be placed on the container again before removing the adapter device.

[0037]For reasons of practical relevance, however, it is assumed in the further description that the substance is present in another container 2 within the container 1. The conta...

second embodiment

[0042]In FIGS. 15a-15e the invention is used in the same way as in FIGS. 11 to 14 except that the intrusions 3 are not drawn into the interior space, but are tied off to prevent the intrusions 3 being filled up with the substance and the container 1 is emptied completely into the extended section 6 of the base body. The adapter device is likewise separated from the container 1 by tying off twice and separating between the tie-off locations from the extended section 6, wherein the tying off twice can be executed above or below the intrusions 3 as desired.

[0043]Furthermore, both embodiments with reference to FIG. 16a-16f and FIG. 1 can have a connection 7, the second embodiment being shown in FIGS. 16a-16f. This connection 7 can serve as a connection to another stage. After the adapter device has been connected to the container as in the preceding embodiments, the connection 7 can be connected to the next stage 11 (FIG. 16b) to which the substance is to be supplied and after opening t...

Abstract

An adapter device for the contamination-free removal of a material from a container (1), wherein the adapter device has a base body (5) which can be connected to the container (1) in a sealing fashion via an open section while surrounding a closure of the container (1), wherein the base body (5) has two intrusions (3) by way of which the material present in the container (1) can be accessed without coming into contact with the material, and at least one additional intrusion (4) into which the sample taken via the intrusion (3) may be guided, and wherein the adapter device is made of a textile or plastic material, for example, a film that is able to be tied-off and separated.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The invention relates to an adapter device for a container and a method for the contamination-free removal of the content of said container using the adapter device.[0003]2. Description of Related Art[0004]For some years, a number of materials have been in use which pose a high risk of contamination to the environment when they come in contact with it or to the persons working with them, and which must have a specific degree of purity for their usage or reprocessing. Such materials, which can be either starting materials, intermediate products or end products, are transported, stored or delivered in various types of containers such as, for example, barrels or sacks. In some cases, it can be necessary to remove a sample of the substances from the corresponding containers. Such sampling is carried out to determine the quality or the degree of purity of the starting materials, intermediate products or end products. Many branch...
