AI Technical Summary

Benefits of technology

The patent is about a method for packaging a chemical compound that requires special labeling. The method involves using a rigid package and a flexible package. The flexible package is filled with the chemical compound and then placed on the adhering layer of the rigid package. The two packages are then closed. The technical effect of this method is that it provides a safe and secure way to package chemical compounds that require special labeling.

Problems solved by technology

These goods may require certifications e.g. for the reason that they are dangerous goods.

The box disclosed in WO 2017 / 135927 A1 is not suitable for packaging certified goods, in particular if the certified goods represent particulate materials, pastes or gels.

In case a package was provided with an access port in accordance with this state of the art package and in case this access port is punctured, the certified goods have air and moisture contact which is detrimental to certified goods or which may even be infringing legal requirements.

A package of this kind is not suitable for packaging certified goods.

However, that's an unattractive job that requires employees being able to understand the label and the link with the product.
