Non-resealable thermoformed packaging for liquid or pasty substances

Abstract

The invention relates to a packaging comprising: a rigid shell that can be deformed by having a user apply pressure, said shell forming a storage space (1) containing a liquid or pasty substance; a breakage area (6) for releasing an applicator (3) for ejecting the liquid or pasty substance from said packaging; and a gripping area (5) including an escape path (7) for said liquid or pasty substance, the escape path being naturally closed when the user applies no pressure such that the liquid or pasty substance is prevented from being discharged after opening the packaging

AI Technical Summary

Benefits of technology

The patent is aimed at providing a non-resealable packaging that ensures safety and is practical to use. The packaging should be leak-resistant, allow contents to flow out homogeneously, and prevent any scratching or injury to the administration site on the subject being treated or fed. The stability of the contents depends on the quality of the packaging material and its interactions with the contents. The patent also aims to address the importance of the dead volume and transparency in affecting the stability of the contents.

Problems solved by technology

A further drawback of currently marketed packaging items, which represent the technical state-of-the-art of the invention, is related to their opening system.

Indeed, after being opened, during application at the site to be treated or fed of a subject, some types of rigid packaging can produce small scratches, for example on the skin or mucosa, due to the presence of sharp edges which appear close to the applicator during opening of the packaging.
