Description

Adapter device for Bβhäiter for kontamiπatioπsfreie removal of their contents

The invention relates to an adapter device for a container and a method for the contamination-free removal of its contents using Adapterer adapter device.

For a number of years, a number of substances that pose a high risk of contamination of the environment when in contact with it, or those working with it and which must have a certain degree of purity for their use or further processing, are used , which may be either starting materials, intermediates or end products are in various containers, such as Barrels or sacks, transported, stored or delivered. In some cases it may be necessary to take a sample of the substances from the appropriate containers. Such sampling will be performed to determine the quality or purity of the starting materials, intermediates or final products. Many industries also carry out such sampling to check the production processes,

As a previous solution for taking samples, cabins are used which have a targeted air flow in which the user opens the corresponding container and takes a sample of the substance, whereby the user himself and the cabin are contaminated with the substance. If the substance to be tested is a hazardous substance, the user must not come into contact with the hazardous substance, thus eliminating the use of a cabin with targeted air flow. In this case, insulators are used in which the user can intervene via glove inserts and remove a sample from the isolator via a slide system. In addition to a sampling, it may also be necessary to take a Teiimenge or the full contents of the container, eg for weighing or for the transfer of the substance in a next stage, in this removal or partial removal are also cabins with targeted air flow to prevent contamination "environment or insulators used to protect the user" Disadvantages of these technologies are that the cabins or insulators need to be cleaned on a different substance than the previous one, which incurs costs, and that a cabin or insulator can be used wherever there are substances must be placed in containers to check or remove.

The object of the invention is to provide an adapter device and a method which / which makes it possible to remove a certain amount of a substance present in a container without endangering the user and without contamination of the environment.

This object is achieved by a device having the features of claim 1 and a method having the features of claim 5.

Advantageous developments of the invention are the subject of the dependent claims.

The basic idea of the invention is to provide an adapter device which has a main body which is connected to the container to be emptied and which has at least one tubular engagement over which the substance present in the container is accessible.

This intervention may further serve as a sluice that functions to engage a portion of the tissue and engage the dressing twice at an arbitrary location and separate between the sites of attachment, thereby rendering the fabric contaminant-free and without endangering the user can be removed. In addition, the main body may have an extended portion into which the container is partially or completely emptied, whereby these withdrawn amounts of the substance in turn can be separated from the container without contamination and without endangering the user by twice setting and separating between the setting sites.

Furthermore, the main body of the device can have a connection, via which the substance present in the container can be fed to a next stage.

Hereinafter, preferred embodiments will be described with reference to the accompanying drawings.

The adapter device is not yet connected to a container 1, which contains a further container 2. With reference to FIG. 2, the base body 5 is fastened to the container 1 via its open section with a fastening device 8, preferably an O-ring. About the interventions 3, the user can open the closure of the container 2, as shown in Fig. 3. As long as container 1 does not contain any further container 2, the adapter device can also be used. In this case, the closure of the container 1 would have to be removed only after the adapter device had been fastened and, after the sample had been removed, removed again before the adapter device was removed. be set. For reasons of practicality, however, it is assumed in further description that the substance is present in a further container 2 in the container 1. The container 2 containing the cloth is also fastened via a fastening device 9, which is applied from the outside around the adapter device (FIG. 3). The substance contained in the container 2 is accessible after attachment of the container 2 via the interventions 3 and 4. As shown in Fig. 4, the user can take one sample from the container 2 via one of the interventions 3, 4, wherein the intervention in Fig. 4 via the intervention 4 and withdraw in άen pulled out of the adapter device engagement 4. In order to separate the taken sample from the container 1 with the adapter device without contamination, the intervention 4 is tied off twice and separated between the tying sites (FIG. 5). After an amount sufficient for a sample has been removed from the container 2, as shown in FIG. 6, the inner container 2 can be closed again via the interventions 3 after removal of the fastening device 9. At this time, the intervention 4 must not have been separated between the Abbindestellen, but this can also be done after closing the container 2, If no further sampling of one of the interventions 3 is desired, the adapter device above the container 1 can also be tied twice and separating them between zones, whereby the container 1 is separated from the adapter device without contamination (Figure 7). If the adapter device has been fastened to a container 1 which has a container 2 after removal of the lid, the remainder of the adapter device (residual foil) which closes the container 1 is not removed again until the next substance removal. Should it be desired to remove the remaining film, for example, to place a closure on the container 1 or to draw a sample, this can likewise, as shown in FIGS. 9a-9d, be carried out without contamination with an adapter. direction can be achieved by the remaining film enclosed by an attached to the container 1 adapter device (Fig. 9a) and the rest of the previous adapter device including attachment as a sample drawn into the engagement 4 and by two times setting and separating between the tying sites of the intervention 4 contamination-free is separated from the container 1 (Fig. 9c and Fig. 9d).
