Description
La présente invention concerne le domaine technique de l’emballage au sens général et elle vise plus précisément, la protection par un emballage, des équipements d’un récipient au sens général, cette protection s’entendant comme la mise en évidence d’une tentative d’utilisation ou d’accès aux équipements ou comme une barrière vis-à-vis de l’environnement extérieur.The present invention relates to the technical field of packaging in the general sense and it aims more specifically, the protection by packaging, of the equipment of a container in the general sense, this protection being understood as the demonstration of an attempt use or access to equipment or as a barrier to the external environment.
L’objet de l’invention trouve une application particulièrement avantageuse pour protéger les équipements des bouteilles de gaz au sens général c'est-à-dire des récipients ou réservoirs sous pression, de forme cylindrique, plus ou moins allongés, conçus pour contenir un gaz à une pression nettement différente de la pression ambiante. Par exemple, ces bouteilles de gaz sont destinées à contenir de l’oxygène, de l’argon, de l’azote, du propane ou du butane.The object of the invention finds a particularly advantageous application for protecting the equipment of gas cylinders in the general sense, that is to say containers or tanks under pressure, of cylindrical shape, more or less elongated, designed to contain a gas at a pressure significantly different from ambient pressure. For example, these gas cylinders are intended to contain oxygen, argon, nitrogen, propane or butane.
L’objet de l’invention trouve d’autres applications pour protéger les équipements de récipients de types différents tels que des citernes, des cuves ou des canalisations.The object of the invention finds other applications for protecting the equipment of containers of different types such as tanks, vats or pipes.
Dans le domaine d’application des bouteilles de gaz, chaque bouteille de gaz est pourvue à son sommet, de divers équipements pour son utilisation tels qu’un chapeau, un obturateur à commande manuelle, un raccord pour la connexion d’un tuyau, un bouchon de sécurité pour le raccord et un indicateur de pression par exemple. Le chapeau de chaque bouteille de gaz présente la particularité de venir coiffer un ensemble d’équipements pour les protéger. Ce chapeau présente des ouvertures pour permettre l’accès à cet ensemble d’équipements et si besoin la préhension de la bouteille de gaz.In the field of application of gas cylinders, each gas cylinder is provided at its top with various equipment for its use such as a cap, a manually operated shutter, a fitting for connecting a pipe, a safety cap for the connection and a pressure indicator for example. The cap of each gas cylinder has the particularity of covering a set of equipment to protect them. This cap has openings to allow access to this set of equipment and, if necessary, the gripping of the gas bottle.
Les divers équipements des bouteilles de gaz sont à protéger notamment de la poussière et de l’humidité. De plus, l’accès à certains équipements est à protéger pour garantir l’inutilisation du contenu de ces récipients. Typiquement, ces bouteilles sont équipées d’un sceau de garantie afin de garantir leur inviolabilité ou leur inutilisation.The various equipment of the gas cylinders must be protected in particular from dust and humidity. In addition, access to certain equipment must be protected to guarantee that the contents of these containers are not used. Typically, these bottles are equipped with a warranty seal to guarantee their tamper-evident or non-use.
Pour pouvoir montrer une tentative d’utilisation, il est connu d’utiliser des bouchons en matière plastique placés sur les raccords. Dans l’état de la technique, il est également connu d’utiliser un manchon en matière plastique thermo rétractable venant coiffer l’ensemble des équipements de la bouteille comme décrit par exemple par le brevet US 6 123 187. Ce manchon thermo rétractable qui présente l’avantage de protéger correctement l’ensemble des équipements s’avère en pratique difficile et long à mettre en place. De plus, une fois rétracté, ce manchon est rigide, coupant et compliqué à retirer. Enfin, ce manchon thermo rétractable ne peut pas être monté sur les bouteilles de gaz ne pouvant pas être chauffées car la mise en place d’un manchon thermo rétractable nécessite le recours à une source de chaleur.To be able to show an attempt to use it, it is known to use plastic plugs placed on the fittings. In the state of the art, it is also known to use a heat-shrinkable plastic sleeve covering all the equipment of the bottle as described for example by US patent 6,123,187. This heat-shrinkable sleeve which has the advantage of correctly protecting all the equipment turns out to be difficult and time-consuming to set up in practice. In addition, once retracted, this sleeve is rigid, sharp and complicated to remove. Finally, this heat-shrinkable sleeve cannot be mounted on gas cylinders that cannot be heated because the installation of a heat-shrinkable sleeve requires the use of a heat source.
Le brevet FR 3 083 783 décrit un dispositif de protection pour un équipement d’un récipient comportant un sac en matière plastique souple présentant une forme générale cylindrique avec une section de passage configurée afin que le sac puisse être enfilé sur l’équipement. Le sac présente un fond fermé et à l’opposé, une ouverture d’accès au volume interne du sac par laquelle le sac est enfilé sur l’équipement. Le sac est pourvu d’une étiquette adhésive permettant, après retrait de sa bande de protection, d’enserrer l’équipement. Un tel dispositif de protection donne satisfaction en pratique. Cependant, pour certaines applications, il apparait le besoin de pouvoir automatiser l’opération de mise en place du dispositif de protection sur l’équipement.Patent FR 3 083 783 describes a protection device for equipment of a container comprising a flexible plastic bag having a generally cylindrical shape with a passage section configured so that the bag can be slipped over the equipment. The bag has a closed bottom and, on the opposite, an access opening to the internal volume of the bag through which the bag is threaded onto the equipment. The bag is provided with an adhesive label allowing, after removal of its protective strip, to enclose the equipment. Such a protection device is satisfactory in practice. However, for some applications, there appears to be a need to be able to automate the operation of installing the protective device on the equipment.
L’analyse de l’état de la technique conduit à constater qu’il apparait le besoin de disposer d’une solution simple à mettre en œuvre pour garantir l’inviolabilité des équipements de récipients et pour protéger notamment de la poussière et de l’humidité, les divers équipements des récipients, cette solution de protection pouvant par ailleurs si besoin être mise en œuvre de manière automatisée.The analysis of the state of the art leads to the observation that there appears to be a need for a solution that is simple to implement to guarantee the inviolability of receptacle equipment and to protect in particular from dust and humidity, the various equipment of the containers, this protection solution can also be implemented automatically if necessary.
L’objet de l’invention vise donc à satisfaire ce besoin en proposant un dispositif de protection pour au moins un équipement d’un récipient, conçu pour garantir l’inviolabilité des équipements de ces récipients et pour protéger notamment de la poussière et de l’humidité, les divers équipements de ces récipients tout en étant de mise en œuvre simple, manuelle ou automatisée si besoin.The object of the invention therefore aims to satisfy this need by proposing a protective device for at least one item of equipment of a container, designed to guarantee the inviolability of the equipment of these containers and to protect in particular from dust and moisture, the various equipment of these containers while being simple to implement, manual or automated if necessary.
