Definitions

  • the present invention relates to a container closure for fastening to a mouth of a container and a container comprising a container closure according to the preamble of the independent claims.
  • a container closure consists of a cap which is screwed onto a mouth of a container and accordingly closes the contents of the container from its surroundings.
  • the containers are typically made of a plastic such as PET and are designed to hold a beverage.
  • the beverages to be consumed are essentially in two forms, on the one hand in a carbonized form, on the other hand in an uncarbonized form. In other words, this means that the drinks are either mixed with carbon dioxide or not. Certain drinks are not artificially mixed with carbon dioxide, but get this through fermentation, such as beer.
  • Container closures of the last-mentioned type are known, inter alia, as so-called flip-top closures. These are container closures that have no thread but are applied le diglich by pressure on a corresponding opening of a Benzol age or a base body.
  • flip-top closures have a closure cap which is attached to the container or to a corresponding base body with a hinge so that they can easily be folded away from a pouring opening. By folding it away, the pouring opening is released and a drink, which is located inside the container, can be dispensed.
  • Such closures are also known under the term sports cap, because they are used in particular when practicing different sports, since such closures can be used with one hand.
  • a container closure is to be created which is easy to use and in particular enables one-handed operation and is preferably suitable for sealing containers with a carbonated drink tightly and, in particular, securely.
  • a container closure according to the invention for fastening to a mouth of a container, in particular for closing an opening of a container comprises a base body for fastening to the container.
  • the main body has a discharge opening.
  • the container closure also comprises a closure cap for closing the discharge opening, the closure cap being connected to the base body in a rotationally fixed manner.
  • the container closure has a locking element for pressing the closure cap against the discharge opening.
  • the locking element is rotatably arranged on the container closure. In front- preferably the locking element is rotatably arranged on the base body.
  • a non-rotatable connection of the closure cap enables it to be removed from the discharge opening to open the container by means of a tilting or folding movement, in the sense of a flip-top closure, and thus to release the discharge opening with one hand.
  • a locking element for pressing the closure cap against the discharge opening makes it possible to also use this container closure to close containers which contain a carbonated beverage.
  • the locking element prevents gas from escaping and the unintentional opening of the container closure due to overpressure in the container.
  • the rotatable connection of the locking element enables it to be rotated into several different positions and in particular to rotate from a locking position in which the closure cap is pressed onto the discharge opening into a release position in which the closure cap can be opened.
  • container closures are typically arranged at an essentially upper end of a container.
  • a container typically has a longitudinal axis that extends through both the container and the corresponding container closure.
  • a container closure accordingly has, along this longitudinal axis, an area or an end that faces the container and an area or an end that faces away from the container.
  • the direction from the inside of the container in the direction of the container closure is the exit direction, that is to say essentially the direction in which a liquid to be dispensed, that is to say the contents of the container, is dispensed.
  • the locking element is preferably designed as a sleeve and has at least one projection for engaging behind an end of the base body on the container side.
  • the projection engages around a container-side end of the base body against the exit direction.
  • the projection is preferably circumferential along an edge of the sleeve.
  • the design as a sleeve enables the locking element to fully engage around the base body along its circumference.
  • the sleeve is preferably designed in such a way that it glides on the base body with an inner surface of its wall and in particular is in contact with it at least in some areas.
  • a projection for engaging behind an end of the base body on the container side enables a force that acts on the locking element to be transmitted to the base body against the exit direction.
  • a circumferential protrusion enables the force to be evenly introduced into the end of the base body on the container side.
  • a force for pressing the closure cap against the discharge opening can be applied and transmitted by the locking element to the base body, in particular to an end of the base body on the container side.
  • the closure cap can have at least two projections for interacting with the locking element.
  • the projections allow the closure cap to be easily pressed against the discharge opening. Due to the interaction between the locking element and the closure cap, forces that act on the closure cap can be transmitted specifically to the locking element. Such forces can arise when there is overpressure inside the container and / or when, for example, a sealing lip is or is to be pressed or pressed against a sealing surface.
  • the sealing lip can be located on the closure cap and the sealing surface on the discharge opening. A reverse arrangement is also conceivable.
  • the locking element can have retaining elements, a retaining element of the locking element being assigned to each projection of the closure cap.
  • the holding elements enable simple interaction with the projections of the closure cap. A simple transfer of the forces is made possible. This in turn enables simple and effective pressing of the closure cap onto the discharge opening.
  • the holding elements are preferably arranged in such a way that they engage behind the projections of the closure cap. It goes without saying that this concerns at least the locking position.
  • the projections are arranged in the locking position after the holding elements, so that a movement of the projections in the exit direction is prevented by the holding elements.
  • the projections of the closure cap and the retaining elements are arranged one after the other in the circumferential direction around the axis, so that the projections slide past the retaining elements or are moved past the retaining elements when the closure cap is opened.
  • the locking element and the closure cap preferably have sliding surfaces which are essentially complementary to one another.
  • the sliding surfaces preferably have an inclination along a direction of movement of the locking element.
  • the sliding surfaces are arranged in particular on the projections of the locking cap and / or on the holding elements of the locking element.
  • the direction of movement of the locking element corresponds to a circular movement in the circumferential direction around the longitudinal axis of the container or around the longitudinal axis of the combination of the container and the container closure as defined here. In other words, the movement is circular.
  • An inclination of a sliding surface along a direction of movement thus corresponds comparatively to the inclination of a thread around the aforementioned axis.
  • the sliding surfaces can be designed according to a flat thread and thus be oriented essentially at right angles to the axis or designed according to a pointed thread and oriented at an angle of more or less than 90 ° to the axis.
  • the inclination of the sliding surfaces also makes it possible that when the closure cap is opened, i.e. when the locking element is rotated from the locking position into the release position, this releases the cap only slowly so that the pressure inside the container can slowly be reduced. A jerky or sudden pressure equalization is thus prevented.
  • a film hinge can be formed on the closure cap.
  • the base body, the closure cap and the film hinge are preferably designed in one piece.
  • a film hinge on the closure cap enables a specific movement of the closure cap when it is opened.
  • the formation of a film hinge enables simple production.
  • the one-piece design of the closure cap together with the base body and the film hinge enables simple production.
  • the container closure as described here is preferably designed in such a way that one of the two projections of the closure cap is formed on the film hinge.
  • the closure cap is pressed or held in the area of the film hinge in the direction of the interior of the container when the locking element is in the locking position.
  • the influence of any residual stresses caused by the film hinge can be reduced.
  • a nose for opening the closure cap can be formed on the closure cap.
  • a tear-off bar can be formed on the closure cap.
  • the tear-off web can have an opening.
  • a pin for a handle can be formed in this opening.
  • the opening and the pin are designed in particular such that when the container closure is in the closed state, the pin engages the opening. It can be provided that the pin is designed, for example, with a mushroom head or that the pin is welded to the tear-off bar when the container closure is closed for the first time.
  • At least one stop can be arranged on the base body.
  • knobs and depressions can be provided on the closure cap and / or on the base body and on the locking element in order to generate haptic feedback about the end position, i.e. the locking position and / or the release position.
  • Such knobs and / or recesses can for example be formed on the projections and on the Hal teiatan and preferably form part of the sliding surfaces.
  • Such feedback can also be achieved, for example, if the sliding surfaces are formed out with a contour in the sense of a cam or a link control.
  • the sliding surfaces can have different gradients. Sealing surfaces which are essentially complementary to one another can be arranged on the closure cap and on the base body.
  • the sealing surfaces can, as described here, have a sealing surface and a sealing lip.
  • the locking element can have a rough surface structure.
  • the rough surface structure is designed in particular as a corrugation.
  • Rotation of the locking element by the user is simplified by a rough surface structure and in particular by a corrugation.
  • the container closure is preferably manufactured using an injection molding process.
  • Polyolefins in particular polyethylene or polypropylene, can be used for production.
  • Another aspect of the invention relates to a container comprising a container closure as described herein.
  • the container and the container closure can thus be matched to one another and, in particular, be offered as a unit.
