Definitions

• the present invention relates to an opening device for packaging containers, in particular for a liquid packaging produced from a material web or a material sheet, according to the preamble of patent claim 1, and a cover element for such a device according to patent claim 21.
• Such opening devices for packaging containers are known, for example, from EP 0 658 480 AI or EP 95 920 224.3, according to which at least one basic element is provided on a packaging, in particular made of a material web or a material sheet, which has an opening, for example in the form of a hole or a hole display is attached in the region of this opening of the container. Furthermore, these known opening devices have at least one cover element for closing the opening, the cover element being attachable to the base element in such a way that the opening can be both closed and opened.
• the preferred type of packaging made from a laminate made from a cardboard or paper core with thermal plastic layers and possibly aluminum foil can be produced from a continuous material web or from individual blanks.
• This type of packaging is often provided with an opening device consisting of a so-called tear strip which is torn off when the package is opened.
• an outer thermoplastic structure which surrounds this strip.
• This thermoplastic structure can be provided with a casting element and a cover element, which can be folded over one another by means of a hinge function and can interlock rigidly in terms of design.
• the strip which is usually located under this thermoplastic structure, often has a part that is unsealed and folded over the sealed section of the strip. This makes it easy to grip the strip when opening the package and tear it off to open the hole or the hole display.
• a packaging container which is formed from a web of packaging material, which consists mainly of paper or plastic material, with a film-shaped film or a tear-open flap made of synthetic resin or tightly seal a plastic bottle.
• the film or the tear-open tab is torn off or the film is pierced with a drinking straw.
• the tear tab can be connected to the innermost layer of the laminate of the container in order to meet the aseptic requirements during the filling of the container. This layer is torn when opening and then removed with the tab in the opening area.
• an opening device for opening the seal of a packaging container at a position for the opening such that an opening section is provided for opening the seal of a sealing part, an actuating section for actuating the opening section and a support section for Supporting the actuating section in such a way that the device for opening the seal is securely attached to the packaging container.
• the opening section can e.g. hinge-like inwards can be used to pierce the pre-perforated opening.
• the aforementioned opening devices all have a thermoplastic structure attached to the opening of the packaging container, which is attached to the surface of the container in the opening region by means of a hot-melt adhesive.
• the disadvantage of these conventional opening devices is, in particular, that the application of these thermoplastic structures is usually made more difficult by expensive positioning devices and that the thermoplastic structure cannot always be reliably detached during transport.
• the material edges of the opening of the packaging container are also not sealed by a thermoplastic structure applied to the surface of the packaging container, so that when the contents of the packaging are poured out, the packaging material softens at the edges of the opening. It is also difficult to reliably disinfect or sterilize such opening arrangements before the packaging is shaped and filled.

• the cover element advantageously has a closure part which serves to close the packaging and which, for example. can be connected to the base part of the cover element by means of a snap, snap, clamp, hinge or screw connection.
• the cover element can be manufactured and assembled separately and, depending on the application, can be shaped differently and perform different tasks. While the packaging with the basic element is completely filled, folded and manufactured ready for packaging or distribution can, the cover element is advantageously attached only in a second manufacturing step.
• the cover element can include a closure part for reclosing the opening, a protective part for protecting the base element from damage caused by the transport of the packaging or, for example. also have a guarantee seal which can be irreversibly changed or destroyed when the packaging container is opened for the first time, so that it can be clearly established whether third parties have already opened the packaging.

It is thus possible to produce opening devices which are equipped with a uniform basic element, while, depending on the embodiment of the packaging or area of application, different covering elements can be implemented by the customer of the packaging, which can be connected to one and the same basic element by means of a standardized connection. The container is thus closed and sealed by the base element and can be opened for the first time using the opening element of the base element. Depending on the type of application, the packaging can then be reclosed by means of a screw closure, by means of a cover, by means of a bayonet closure or, for example, also by a cover element designed as a hinged closure.
