Definitions

  • the invention relates to a resealable closure for a container, in particular a beverage can, with a lid which closes an opening in the container or releases it for removal of the contents of the container, according to the features of the preamble of claim 1.
  • Containers especially beverage cans for carbonated drinks, are known. These are usually made of a deep-drawn light metal, the side walls, the bottom and the upper part of the container form a space for receiving the content, in particular a liquid.
  • the upper part is provided with a punched, which forms a cover. When the lid is removed, an opening in the container for removal of the contents of the container is released. This has long been known and works basically satisfactory, but has the disadvantage that the opening that has been released once from the lid can not or only insufficiently be closed again.
  • the invention has for its object to provide a resealable closure for a container, which is improved over the prior art, in particular with regard to its production and function on the one hand a reliable and permanent closure of the container, in particular for carbonated contents, forms before the lid has opened the opening in the container for the first time and which, after the first release, allows the once released opening to reliably close again.
  • the closure has a frame on which the lid is movably mounted, and a seal surrounding the opening, with which the frame is sealed relative to the container.
  • the geometry of the frame and its associated around the opening of the container circumferential seal can be optimally adapted to the opening in the container.
  • the container can be filled with its contents, in particular sterile filled, before the frame is placed with its lid and thus the container is completely closed.
  • the cover which is movably mounted on the frame, can be adapted to the geometry of the frame in the sense that in the preassembled position (first position) of the lid, the opening formed by the frame , durable and reliable, especially before outgassing, closes and only then releases the opening for removal of the content from the ratio when it is brought by a user from the first (closure) position to the second position, that is, the position releasing the opening in the container.
  • the geometries of the frame and lid are coordinated so that they can optimally achieve their functions in the two positions. It is particularly important that in the first position, a seal of the interior of the container is ensured against its external environment and then, when the lid is in the second, opening position, the contents of the container for the user is the best possible accessible.
  • the frame has at least one web pointing in the direction of the interior of the container, with which the frame can be fixed in the opening in the container. If there is a single web, it is advantageously designed to be completely radially encircling and has one Geometry, which allows the frame is inserted with the pointing in the direction of the interior of the container web in the opening in the container and fixed there after insertion of the web. This is done in an advantageous manner by a catch, an undercut, a gluing, caulking or the like. Alternatively, it is conceivable that not a radially encircling web, but several, located on a circumference webs are present, which allow the same as with the one circumferential web.
  • the frame and the peripheral seal around the opening are formed as a two-component component.
  • the frame and the circumferential seal around the opening are formed as separate parts and the seal fixed by means of positive engagement with the frame.
  • This provides the advantage that the two parts (frame and seal) can be manufactured separately from one another from different materials in the same or different manufacturing processes. After both components have been produced, they are fixed to one another by means of positive locking, so that the component prepared in this way can be inserted and fixed in the opening in the container as described above.
  • the frame is also manufactured in a plastic injection molding process, while the peripheral seal is for example an O-ring, which is fixed by means of positive engagement with the frame, which has a corresponding receiving geometry for the seal.
  • the cover itself is formed by a frame and a cover held by the frame, wherein the cover closes the opening in the container.
  • the lid is not, as previously described, integrally formed, but in this case in two parts.
  • more than two parts for forming the lid are also conceivable.
  • This two- or multi-part design of the lid has the advantage that it can be optimally designed in terms of its function.
  • the cover has the task that it can be handled by the user without any problems.
  • the frame is necessary, which gives the movable lid stability.
  • the frame for example, also made of plastic and hergesteilt in a plastic injection molding process.
  • the cover held by the frame has another function, namely to close the opening in the container and, above all, to seal it, so that neither outgassing outside the interior of the container, outside, external influences, in particular contamination, can not penetrate from the outside into the interior of the container. Therefore, the cover is designed to perform the above function. For this purpose, it also consists, for example, of a plastic material, which can also be processed again in a plastic injection molding process. While the frame gives the lid the required stability and is made of a strong plastic material, the cover held by the frame is also made of a plastic material, especially for hygienic reasons, but softer to the hard plastic material of the frame.
  • the frame of the lid and the cover held by the frame are formed as separate components and the cover is fixed by means of positive engagement with the frame of the lid.
  • these two components can be produced optimally in terms of material and manufacturing process by their separate production and are assembled together only after their preparation. This is done in an advantageous manner by means of positive locking, to which the geometries of the frame and cover are coordinated.
  • the cover is simply pressed into the corresponding recess of the frame.
  • caulking, welding, gluing, latching and the like are conceivable.
  • the frame is made of hard plastic material, opposite the cover of a softer plastic material.
  • the frame of the lid and the cover held by the frame are advantageously designed as a two-component component.
  • the frame and the cover by means of a Kunststoffstöffspril gussvelfalirens made in a tool dääüTclT; that the frame from the first, in particular hard Kunststoffmateriai, and then the cover, in particular from the softer plastic material, injected.
  • Ansteife of which also the frame of the lid can first be produced in a plastic injection molding process in a corresponding tool and this frame thus produced are used in a second tool, where then the cover of another plastic material is molded onto the frame.
  • the lid has a valve.
  • a valve has the advantage that between the interior of the container and the external environment, if necessary, a pressure equalization can take place.
  • the valve is designed in a particularly advantageous manner to the effect that only a pressure equalization can take place from the interior of the container in the direction of the external environment.
  • a pressure equalization of the external environment in the direction of the interior of the container should be prevented. This makes it possible in an advantageous manner, to prevent or reduce a resulting inside the container pressure, in particular a harmful or even dangerous pressure.
  • the valve is designed so that it allows only a gaseous pressure equalization (venting), but at the same time prevents this liquid from escaping from the inside of the container.
  • valve is arranged in the cover, which is arranged in the frame of the lid.
  • the lid is either pivotally or displaceably arranged on the frame, which is inserted into the opening of the container. This results in terms of handling for closing or for releasing the opening in the container different options, which in particular meet the desire of the user for different ways to operate the lid.
  • the lid may be formed one or more parts.
  • a frame 1 is shown, which can be used according to its geometry in an opening not shown here in a container, also not shown and permanently and sealingly fixed in this opening by appropriate measures.
  • the frame 1 also forms an opening, wherein the opening formed by the frame 1 is at least equal to or smaller than the opening area of the opening in the container.
  • a lid 2 is provided for closing or releasing this opening.
  • the frame 1 has a seal 3.
  • Frame 1 and seal 3 are either separate from each other and feumblebare by positive engagement Components are barren as a one-piece component, in particular made ⁇ 'by a two-component injection molding of plastic. The determination of the frame 1 by means of a web.
  • the web is either one piece, radially around the opening in the container around circumferentially formed (not shown here) or consists of a plurality of webs 4, wherein the plurality of webs 4 are arranged like a circle.
  • the geometry of the plurality of webs 4 is chosen so that with them the frame 1 is fixed to the container when the frame is inserted into the opening, in this case, the plurality of webs 4 has a corresponding undercut.
  • the frame 1 can also be fixed to the container in a different manner. If the frame 1 is fixed by means of the webs 4 to the container, the underside of the seal 3 rests on the surface of the container, so that thereby the sealing function of the frame 1 is realized with respect to the container.
  • FIG. 2 shows that the cover 2 has at least one joint 5, here two joints 5.
  • the lid 2 is pivotally fixed to the frame 1.
  • the frame 1 has corresponding counter means for receiving the joints 5 of the lid 2.
  • the cover 2 has at least one latching element, here two latching elements 6, with which the cover 2 is held in its closed position on the frame 1.
  • the cover 2 in this embodiment has a frame (no reference numeral), this frame accommodating a cover 7.
  • the frame and the cover 7 of the cover 2 are either two components manufactured separately from one another or they are produced in a production process, in particular in a two-component plastic injection molding process.
  • the cover 7 is designed in terms of their geometry so that it closes the opening formed by the frame 1, or after the pivoting of the lid. 2 releases.
  • the cover 7 is made of a material which is softer against the material of the frame 1 and the frame of the Deckenis 2. This ensures on the one hand that with the cover 7, the opening in the container, formed by the frame 1, is effectively closed, but can be released gieichzeitig after pivoting the lid 2, so that the contents of the container can be removed.
