Definitions

  • the invention relates to a wall part for containers, in particular packaging and storage containers.
  • Containers in particular packaging or the like, are frequently provided with predetermined breaking points at at least one point on the container or packaging wall. By manually exerting force on these predetermined breaking points, the consumer is able to open the container or the packaging. Especially in the field of plastic and cardboard packaging, a perforation of the packaging material is usually provided as the predetermined breaking point.
  • the aim of the present invention is therefore to provide a container wall part with perforation which does not have the disadvantages mentioned above and by which the ingress of liquids or dirt particles can be reliably prevented.
  • this aim is achieved by a wall part for containers or the like, which has at least one perforation and a sealing means for preventing the penetration of liquids, particles or the like through the wall part in the region of the at least one perforation, the sealing means having the at least one Perforation covering is arranged on a first side of the wall part.
  • the wall part can on the one hand be part of the container.
  • the wall part according to the invention is suitable for attachment to gas outlet openings, such as occur in the automotive industry with belt tensioner or airbag modules. In this case too, the penetration of liquids or dirt particles is undesirable, since the function of belt tensioners and airbags would otherwise be impaired or even fail completely, with the consequences being fatal.
  • the wall part according to the invention can also be used as a cover for an ejection opening for an airbag.
  • the wall part is designed as a label. It is particularly advantageous here to make the label self-adhesive. For this purpose, it can further be provided that on the side facing away from the first side of the wall part, at least in sections
  • Adhesive layer is attached. Such a label can then easily be applied to any type of packaging. In addition, it is possible to protect all types of openings from the ingress of dirt, moisture and the like. Existing packaging can be easily retrofitted with "moisture protection”.
  • a lacquer layer is provided as the sealing agent.
  • a layer of lacquer has the advantage that it can be attached to the wall part in a simple manner. For this purpose, it is provided according to an advantageous variant of the invention that the lacquer layer is printed. So can in the mass production of wall parts

  • the sealing means is an easily breakable film.
  • the film can be designed in such a way that it yields and breaks at a certain pressure. This means that the entire wall part becomes permeable in the area of the perforation. This ensures that packaging or the like can be opened by exerting an appropriate force on the sealing means and the perforation underneath.
  • the pressure at which the wall part becomes permeable is particularly critical since the perforations above the openings have to tear open at a defined pressure at the gas outlet openings , so that gas can escape and any remaining pressure can be released after the belt tensioner or airbag has been triggered.

Abstract

La présente invention concerne une partie de paroi (1) destinée à des récipients, en particulier à des emballages et analogue. L'ouverture des emballages est possible grâce à une perforation (3) dans la partie de paroi (1). Les perforations peuvent cependant être à l'origine de la pénétration à l'intérieur de l'emballage, de saleté, de particules de poussière et de liquides susceptibles de s'ajouter au contenu, en particulier aux aliments et aux denrées périssables qui s'y trouvent, et de les altérer. Pour cela, la perforation de la partie de paroi de l'invention est dotée d'un élément de protection (4). La partie de paroi peut être intégrée à un emballage préexistant ou à un récipient. Eventuellement, on utilise une partie de paroi (1) qui se présente sous la forme d'une étiquette que l'on peut coller au moyen d'une couche de colle (2) sur tout type d'ouverture à protéger.
