Definitions

  • the present invention relates to a device and a method for producing filled containers such as US 9,643,746 B1 is known.
  • Numerous devices and methods of this type are known from the prior art.
  • a container is usually first filled with a liquid and then closed with a closure.
  • Methods are known in the prior art in which an inert gas is filled into the headspace of containers that have not yet been closed, in order to extend the shelf life of the beverage in question. This procedure is known in particular in so-called hot-fill processes, in which a heated liquid is filled into the containers.
  • methods have also become known in which the containers are first closed, for example with a plastic closure, then this plastic closure is pierced again and the inert gas is filled through the opening thus created into the head space of the container. The opening created is then closed again.
  • the present invention is therefore based on the object of making such devices known from the prior art ready for series production.
  • a device according to the invention for producing filled containers has a transport device which is suitable and intended for transporting containers filled with a liquid and closed with a closure.
  • the device has a penetration device which is suitable and intended to create an opening in at least one area of the closure and/or the container and an application device which fills an interior of the container with a flowable and in particular gaseous medium through this opening applied (or this interior supplies the gaseous medium).
  • closures are preferably closures that have been manufactured using a compression molding process.
  • Another preferred device is closures that have a continuous or substantially continuous wall thickness.
  • closures to be used that were produced in an injection molding process.
  • the closure is designed in one layer.
  • the closure preferably has no so-called liner on its inside.
  • the device has a closing device which closes the opening again (and which closes the opening again in particular after the interior space has been acted upon by the gaseous medium).
  • the device has a sterilization device which sterilizes at least one area of the closure and/or the container.
  • account is taken of the fact that the creation of the opening and the subsequent opening of the container can lead to contamination or contamination of the beverage.
  • this first measure also allows corresponding systems to be ready for series production since, as explained in more detail below, a series or industrial production of containers is also made possible.
  • the containers are filled with a heated liquid and in particular with a heated beverage.
  • the liquid preferably has a temperature which is greater than 30°, preferably greater than 40°, preferably greater than 50° and particularly preferably greater than 70°.
  • the closing device has an ultrasound generating device.
  • Closing devices are known from the internal state of the art of the applicant, which reheat the region of the opening of the lid, for example by heating. In this case, however, only a specific area of the lid is heated and welded in this way.
  • Ultrasonic welding also prevents the formation of toxic gases as in the case of heat smelting. In addition, no melted material can drip from the lid into the container.
  • the device has at least one inspection device which monitors at least one device of the device and/or the device has at least one monitoring device which monitors at least one parameter that is characteristic of the production of the filled containers.
  • the operational safety or the process safety of the containers produced in this way is ultimately increased.
  • this measure also contributes to the fact that the containers are manufactured in ongoing production.

  • the cleaning and/or sterilization device may clean or sterilize other elements of the device, such as the penetration device or the closing device.
  • the application device enables the container to be subjected to a first pressure and a second pressure, which differs from the first pressure. This approach is fundamental proposed that the medium is supplied with different pressures through the opening.
  • containers and in particular hot-filled containers are generally pierced through the closure after recooling and pressurized with a gaseous medium, in particular an inert gas and in particular nitrogen.
  • a gaseous medium in particular an inert gas and in particular nitrogen.

  • the ultrasound generating device has a processing head that can be advanced onto the closure and/or the opening, which in turn has a surface that can be turned towards the opening and is designed in such a way that it is suitable for urging molten material in the direction of the opening.
  • a sonotrode is used for ultrasonic welding, for example of a hole pierced in the lid. As mentioned above, this is placed on the cover in order to close the hole there again by melting the material using ultrasound.
  • the Applicant has found that with certain shapes of this sonotrode, although a nice weld is obtained, due to a specific shape of the sonotrode, for example a round shape, the tip cannot always be guaranteed to weld the existing hole. This is because certain sonotrode shapes melt the material but carry the melted material away from the pierced hole.

  • the surface that can be turned towards the opening is understood to mean that component or in particular that end face of the sonotrode which is arranged closest to or at the smallest distance from the opening during the working process. It is suggested, that this surface is designed in such a way that it urges molten material towards the opening.
  • this surface is concavely curved. As will be described in more detail below, this curved surface achieves an urging of the melted material towards the opening. Instead of a curved configuration, however, an angular configuration would also be possible, for example in the shape of a cone or the like.

Therefore, according to the invention, the concave embodiment described here is present on several sides, namely on both sides of the sonotrode. In this way, a symmetry of the sonotrode can be achieved.
  • the melt is carried over the hole to be closed by the concave head and in particular the concave tip during welding, so that there is always a certain layer thickness over the hole to be closed.
  • a more reliable welding and/or reclosing of the hole in the container, or its closure can be guaranteed, in particular by a concave shape of the sonotrode, since edge material is carried and/or pushed directly over the hole with each weld.
  • the surface of the sonotrode which contacts the cover is particularly preferably symmetrical and, in particular, circular in cross section.
  • the ultrasound generating device can be advanced onto the opening in such a way that a longitudinal direction of the ultrasound generating device encloses an angle that is greater than five degrees, preferably greater than ten degrees, preferably greater than 15 degrees, relative to a direction standing on a surface of the closure and preferably greater than 17 degrees.
