Thermoformed packaging intended to deliver a liquid or pasty substance, said packaging comprising: a rigid shell, which is deformed under the action of a pressure exerted by a user, said shell forming a reservoir, said reservoir containing said liquid or pasty substance; a breakage area that can be torn, broken or cut, intended to release an applicator for ejecting the liquid or pasty substance from said packaging; and a gripping area comprising an escape path for said liquid or pasty substance, said packaging being non-resealable, characterised in that the escape path is formed from a narrow contact area that is not sealed between a bottom complex of a first thermoformable rigid film and a sealing complex of a second flexible film, said first and second films forming two different materials, said contact area being delimited by a sealed area of said first and second complexes, in such a way that: said escape path is naturally closed in the absence of a pressure exerted by the user in such a way as to block the exiting of said liquid or pasty substance after opening of the packaging, the deformation of the reservoir under the action of the pressure exerted by the user flushes the liquid or pasty substance towards the applicator through the escape path; and said escape path is opened by deformation of the flexible portion of the escape path allowing for the escaping of said liquid or pasty substance. a rigid shell, which is deformed under the action of a pressure exerted by a user, said shell forming a reservoir, said reservoir containing said liquid or pasty substance; a breakage area that can be torn, broken or cut, intended to release an applicator for ejecting the liquid or pasty substance from said packaging; and a gripping area comprising an escape path for said liquid or pasty substance, said packaging being non-resealable, characterised in that the escape path is formed from a narrow contact area that is not sealed between a bottom complex of a first thermoformable rigid film and a sealing complex of a second flexible film, said first and second films forming two different materials, said contact area being delimited by a sealed area of said first and second complexes, in such a way that: said escape path is naturally closed in the absence of a pressure exerted by the user in such a way as to block the exiting of said liquid or pasty substance after opening of the packaging, the deformation of the reservoir under the action of the pressure exerted by the user flushes the liquid or pasty substance towards the applicator through the escape path; and said escape path is opened by deformation of the flexible portion of the escape path allowing for the escaping of said liquid or pasty substance. said escape path is naturally closed in the absence of a pressure exerted by the user in such a way as to block the exiting of said liquid or pasty substance after opening of the packaging, the deformation of the reservoir under the action of the pressure exerted by the user flushes the liquid or pasty substance towards the applicator through the escape path; and said escape path is opened by deformation of the flexible portion of the escape path allowing for the escaping of said liquid or pasty substance.
