Definitions

  • the invention relates to a packaging for pourable or flowable products, having a packaging cover which is positioned in a plane and has an opening, the opening being closed in the packaging cover by a sealing element.
  • the invention also relates to a packaging made of metal that is filled with a carbonated medium and to a use of a sealing element.
  • Packagings of this type are known, for example, as conventional beverage cans.
  • a region is punched out of the cover surface and provided with a handle in such a way that the punched-out cover region can be removed by pulling on the handle. This allows the can to be opened—however, the can may no longer be closed using this opening arrangement.
  • EP 1607341 discloses a packaging cover with a withdrawable sealing element and a closure means which is arranged thereabove and allows the opened packaging cover to be reclosed once the sealing element has been removed.
  • the invention is therefore based on the object of developing a packaging for pourable or flowable products in such a way that it can be manufactured in a simple manner and offers major customer benefit.
  • the sealing element has a sealing frame and a sealing cover which can be at least partially separated from each other for emptying, the sealing frame remaining connected to the packaging cover during emptying, and which are positioned approximately in the plane of the packaging cover.
  • the invention allows a packaging cover provided with a sealing element to be manufactured in a form allowing complex add-ons above the packaging cover to be dispensed with while still combining the seal and closure functions in the cover plane.
  • the new packaging allows individual packagings to be stacked one above another without closure elements on the packaging cover preventing this.
  • the sealing element extends at least partially into the opening.
  • An advantageous embodiment provides for the sealing frame and sealing cover to be embodied in one piece with a predetermined breaking point.
  • This allows the sealing element to be manufactured as a single part, such as for example an injection-molded part made of plastic, in which the sealing frame and sealing cover are separated in a simple manner by a predetermined breaking point prior to the emptying of the packaging.
  • the one-piece embodiment facilitates the manufacture and the connection of the sealing element and packaging cover.
  • a notch be arranged between the sealing frame and sealing cover.
  • Another embodiment provides for a weld line to be arranged between the sealing frame and sealing cover.
  • the sealing cover may be beneficial for the sealing cover to remain connected to the packaging even once the packaging has been opened.
  • This further connecting point can be embodied in a particularly secure manner in order still to obtain a connection between the sealing frame and sealing cover even once the sealing frame and sealing cover have been detached in the region of the predetermined breaking point.
  • the further connection can also be embodied in a particularly brittle manner in order to facilitate commencing, at a specific point, of the breakage between the sealing frame and sealing cover along the predetermined breaking point.
  • sealing frame and sealing cover For production-related reasons, and in particular in the case of a one-piece manufacture of the sealing frame and sealing cover, provision is made to make the sealing frame and sealing cover from the same material, in particular an injection-moldable plastics material. It is therefore proposed, in particular, that the sealing frame be manufactured by injection molding or injection-compression molding.
  • sealing frame sealing cover and if appropriate also a handle must meet different requirements, and also the connecting regions between these parts are intended to satisfy specific requirements, it is proposed that the sealing element be made from different materials.
  • the sealing frame can be made from a different material to the sealing cover.
  • transition regions, fastening regions, such as flanges, or else breaking point regions can also be made from a different material to the materials surrounding this region. This allows, in particular, plastically deformable and resilient materials to be combined with one another in order to combine, for example, a solid sealing frame with a more readily deformable sealing cover.
  • the sealing frame and sealing cover be manufactured in a sandwich injection mold.
  • This allows, for example, the sealing frame to be made from a different material to the sealing cover. It is however also possible to make the region of transition between the sealing frame and sealing cover from a different material or to provide further components, such as for example a handle or the connection to a handle, in a different material.
  • the sandwich injection mold also allows a selection of various colors for different regions of the sealing element.
  • the sealing element has a spout for emptying.
  • This spout is preferably embodied on the sealing frame, so that it remains on the packaging cover during emptying of the sealing cover.
  • the sealing cover may also be embodied as a spout.
  • the sealing element has at least one radially outwardly protruding flange.
  • a flange of this type allows the sealing element to be fixed with this flange to the inside of the packaging cover or the sealing element to be fixed with the flange to the outside of the packaging cover.
  • a particular embodiment provides for the boundary region of the opening in the packaging cover to be received between two flanges of the sealing element. This allows a secure, correctly positioned arrangement of the sealing element relative to the packaging cover.
  • a particular embodiment provides for the sealing element to be connected to the boundary region of the opening via a thread or bayonet. This allows the sealing element, and in particular the sealing frame of the sealing element, to be screwed into an opening in the packaging cover.
  • a particularly advantageous embodiment leads to a reclosable closure.
  • the sealing cover is embodied in such a way that it, once it has been removed from the sealing frame, can be reconnected to the sealing frame as a closure cap.
  • the sealing cover thus has a first function as a seal and is connected to the sealing frame preferably via a predetermined breaking point in order to ensure for the user, in the state in which the packaging is dispatched, that the packaging has not previously been opened by third parties. Once this seal has been removed, the seal is not—as is conventional—thrown away; instead, the seal is embodied in such a way that it can be reconnected to the sealing frame as a closure cap.
  • the sealing cover can, once it has been removed from the sealing frame, be reconnected to the sealing frame in substantially the same position.
  • an advantageous variant embodiment provides for the sealing cover to be embodied in such a way that it, once it has been removed from the sealing frame, can be reconnected with the outwardly pointing inside to the sealing frame.
  • the sealing cover is advantageously made for the sealing cover to be embodied in such a way that it, once it has been removed from the sealing frame, can be reconnected in a locking manner to the sealing frame as a closure cap.
  • this locking connection allows the sealing cover to be reconnected to the sealing frame in a simple manner and, even thereafter, the packaging to be repeatedly reopened and closed in a simple manner.
  • sealing cover to be embodied in such a way that it, once it has been removed from the sealing frame, can be reconnected to the sealing frame as a closure cap by means of adhesive strips.
  • An adhesive strip is particularly suitable specifically with regard to a simple and particularly flat connection between the sealing cover and sealing frame for temporarily sealing the packaging.
  • the sealing cover can be connected to the sealing frame via a thread or a bayonet closure as a closure cap in order to be easily removable and re-placeable.
  • An advantageous embodiment provides for the sealing cover to be embodied in such a way that it, once it has been removed from the sealing frame, can be inserted into a clamping cone of the sealing frame as a closure cap.
  • the clamping cone alone can lead to an adequate connection.
  • the clamping cone can also additionally have a locking arrangement in order to attain optimum positioning of the sealing cover in the sealing frame as a closure cap.
  • a handle of this type can be embodied in manifold ways and manners.
  • a handle is rigidly connected to the sealing element.
  • the handle is designed in one piece with the sealing element. It is advantageous if the handle is molded onto the sealing cover.
  • a first variant embodiment provides for the handle to form a lever or eccentric to facilitate breakage at a predetermined breaking point.
  • the handle has a spike-like design to act on the predetermined breaking point.
  • a particularly advantageous exemplary embodiment provides for the handle to be integrated into a closure cap.
  • One exemplary embodiment provides in this case for the handle to be embodied as a formed part of a closure cap that can be connected to the sealing frame in a locking manner.
  • An alternative provides for the handle to be embodied in such a way that it can be connected to the packaging cover in a locking manner.
  • a second handle be arranged on the side of the sealing cover that opposes a first handle.
  • a second opening which is closed by a second sealing element, be provided in the cover. This allows the packaging to be emptied through the first opening, while air can subsequently flow into the packaging through the second opening.
  • the second opening is formed in a sector substantially opposing the first opening.
  • the described closure mechanism is suitable for a broad range of types of packaging.
  • the type of closure offers particular advantages to a can, as it can be embodied in a particularly simple manner on a can cover without the height of the can significantly increasing as a result.
  • one exemplary embodiment of the invention provides for the packaging to be made from a metal. Particular advantages open up if the packaging has a seamed cover, as this seaming provides a restricted height remaining for the closure in which only specific types of closure can be arranged.
  • the embodiment of the closure opens up a broad field of applications for packagings of this type.
  • the type of the closure allows the packaging to be filled with carbonated liquids which build up a certain internal pressure which the closure must withstand. Therefore, the closure is ideally suited, in addition to a large number of further possible applications, to packagings filled with a lemonade or beer.
  • the invention therefore also leads to a packaging made of metal that is filled with a carbonated medium and has a plastic part embodied as an opening and to a use of a sealing element made of plastic for a packaging made of metal that contains a carbonated medium.
