Abstract

Cette invention se rapporte à un récipient à réactif tenant dans un bouchon pour des réactifs d'analyse, qui permet d'analyser de façon simple la qualité d'une eau. Un des problèmes techniques de cette invention est de réaliser un récipient à réactif tenant dans un bouchon pour des réactifs d'analyse, qui permet à un opérateur d'analyser la qualité d'une eau de façon sûre et précise en une seule opération, même sans avoir de connaissances en chimie. Une solution à un premier problème technique de cette invention est de réaliser un corps de récipient transparent permettant d'injecter une quantité prédéterminée d'eau à tester depuis une ouverture du récipient, un corps de bouchon pouvant être monté par serrage sur un côté de l'ouverture du corps du récipient, un récipient renfermant le réactif monté dans le corps du bouchon et renfermant un réactif prédéterminé, ainsi qu'une lame conçue pour être poussée à l'intérieur du corps du bouchon selon une force avec laquelle le corps du bouchon est serré sur le corps du récipient, afin de rompre le récipient renfermant le réactif monté dans le corps du bouchon, pour que le réactif puisse se déverser dans le corps du récipient, comme décrit dans la revendication 1. Grâce à cette solution, lorsque le corps du bouchon dans lequel tient le récipient renfermant un réactif prédéterminé, est monté sur l'ouverture du corps du récipient de façon serrée, après qu'une quantité prédéterminée de l'eau à tester a été injectée dans le corps du récipient transparent, la lame est déplacée selon une certaine force de serrage, pour que le récipient renfermant le réactif soit rompu, permettant ainsi au réactif contenu dans le récipient renfermant le réactif de se déverser dans le corps du récipient transparent. Ainsi, lorsqu'il s'agit de procéder à une analyse de l'eau à tester, le fait de serrer le corps du bouchon sur le corps du récipient transparent, dans lequel a été injectée l'eau à tester, permet de mélanger le réactif avec l'eau à tester, pour qu'un opérateur puisse effectuer une analyse de la qualité de l'eau de façon sûre et précise en une seule opération, même sans avoir de connaissances en chimie.
