Definitions

  • the invention relates to a closing and opening device for opening and closing a beverage container according to the preamble of claim 1.
  • Such a generic closure and opening device is known from DE 10 2005 015 505 A1.
  • this type of closing and opening device allows its operation with only one hand and with a relatively small amount of force.
  • the special feature of this closure is its lid, which can reversibly change its geometry.
  • the lid in the closed state has the geometry of a spherical section.
  • a subsequent action of a second force on the edge of the lid leads to a reverse deformation of the same in its initial geometry, in which the lid again closes and seals the liquid container.
  • the described operation is achieved in this known closing and opening device by a arranged below the cover multi-armed support and spring structure which is connected to the lid and supports it in its deformation.
  • the invention has the object, a generically designed closing and opening device for beverage containers educate so that it is completely gas-tight and liquid-tight in the closed state and after their initial opening.
  • the attachment of this closing and opening device on the beverage container should be designed so that it is gas-tight and liquid-tight at each actuation state.
  • the invention is based on the finding that the closing and opening devices known from DE 10 2005 015 505 A1 and DE 10 2007 035 728 A1 must be equipped with additional gas-tight and liquid-tight sealing means in order to achieve improved tightness. In this case, much higher requirements are directed to the tightness before the first opening of the device than to the sealing properties after the initial opening of the same.
  • the arranged below the cover multi-armed support and spring structure is changed in their construction.
  • the invention is therefore based on a closure and opening device for a beverage container having a fastening portion for attachment to the open end of the beverage container and a lid, with which the device can be opened and closed by exerting a compressive force on the same, by exercising a first pressing force F1 from the outside to a central region of the lid opens the device and closes by the exertion of a second compressive force F2 from the outside to the radial edge of the lid, the device in which the attachment portion and the lid with a multi-arm, elastic support and spring structure are connected, which is arranged radially inside the mounting portion and axially below the lid, and that sealing means are present on the closing and opening device, which seal the same in the closed state.
  • a protective film on the closing and opening device is gas- or liquid-tight formed or attached, which is arranged such that these at a first time exercise of a force acting on the lid F1 to open the same components of the support and spring structure or is destroyed by a separate, connected to the support structure and spring separation device.
  • the integration of a protective film in the closing and opening device allows notwithstanding the previously known generic devices that such equipped beverage containers can now also accept carbonated drinks without having to be expected before the first use with a leakage of carbon dioxide or the drink.
  • the closing and opening device according to the invention is therefore ideal for beverage cans made of metal or plastic, in which, for example, mineral water, lemonade or beer should be kept. After the first opening of the closing and opening device to the beverage container, this can be closed again with the known closing mechanism so far that a liquid and gas outlet is at least greatly inhibited. In any case, this closing and opening device prevents the unwanted intrusion of animals or foreign matter into the beverage container.
  • the inventive design or coupling of the support and spring structure of the closing and opening device with a separator that automatically destroys the protective film when first pressed the same that the drink can be removed from the beverage container allows a very practical use of the same.
  • the closing and opening device according to the features of the main claim is provided that by the fixing portion and the multi-arm, elastic support and spring structure of the closing and opening device referred to as a cover base component is formed, which has on its cover remote and therefore close to the drink side the protective film, and to which the lid is fastened.
  • a cover base component is formed, which has on its cover remote and therefore close to the drink side the protective film, and to which the lid is fastened.
  • the production of the lid in a separate manufacturing process appears to be appropriate because of the comparatively complicated structure of the lid base, but it is also possible to produce the lid together with the lid base in a plastic injection molding process in a common tool, the lid base and the lid over a plastic -Filmschamier are initially connected to each other captive, but separated from each other for their final assembly at this point and are connected to one another for the later functions meaningful other place again.
  • the separating device can also be provided that it is connected to the radially inner ends of the arms of the support and spring structure and therefore arranged in the center of the closing and opening device.
  • the separating device has in a preferred embodiment of individual, knife-like cutting, which are arranged aligned in the direction of the protective film. Although these cutting the separator consist of relatively thin plastic parts, these are due to the small thickness of the protective film and the need for a single use very well suited for destroying the protective film.
  • the cutting of the separation device in the center of the lid base are connected to each other by means of a preferably round connector, on which the lid is fastened.
  • the cover located in the closed position is curved so that it can easily lift the cutting of the separator and keep safe from the first use of the protective film.
  • the said connecting piece, on which the cutting edges of the separating device are fastened has a receiving opening on its side facing the cover, into which a pin protruding axially from the center of the lid can be inserted or removed in a captive manner. is latched.
  • the pin on the lid preferably has a blind hole centrally or coaxially with respect to its longitudinal axis, so that its deformability with respect to the Einfäddeins is improved in the receiving opening of the connector of the lid base compared to a solid design of the pin.
  • the receiving opening is cup-shaped on the connecting piece and has on its inner wall an annular groove into which an annular web of the pin can be latched.
  • the connecting piece is formed thorn-shaped.
  • the connector has, for example, a conical outer geometry, which tapers towards the undestroyed protective film.
