Definitions

  • the invention relates to a container closure according to the preamble of claim 1.
  • container closures which have a lid arranged in an articulated manner on a retaining ring, whereby the lid is also held captive on the container.
  • This folding function of the lid is particularly important for food containers, since the lid does not have to be stored separately and can therefore neither become dirty nor lost.
  • the cover can be pivoted around the hinge from a closed position into an oven position. It is known that the lid can be locked in the open position on the retaining ring. For this purpose, a first extension formed on the cover can latch in a second extension formed on the retaining ring in the open position of the cover. This prevents the lid from accidentally falling into the pouring stream of the filling material while the container is in use.
  • the locking can be released and the lid can be pivoted from the open position into the closed position in order to close the pouring opening.
  • the lid has to be pivoted through a large pivoting range of approximately 200 degrees, which is impractical for the user.
  • the disadvantages of the described prior art result in the object of improving a container closure with a pivotable lid.
  • the aim of the invention is to improve the user-friendliness of the container closure for the end consumer as well as for the industrial filler. description
  • the invention is preferably characterized in that the sealing element has a height and has formed a retaining tongue in that the height of the sealing element in the area of the joint is higher than on the rest of the circumference of the sealing element, and that the cover can be pivoted into a second open position, in which the retaining tongue can rest against the open edge of the pouring opening or the upper edge of the retaining ring.
  • the user can therefore choose individually between two open positions of the cover.
  • the first or the second open position can be advantageous. If the contents of the product are small, the container must be more inclined for pouring. In this case, the cover is advantageous in the first open position, in which it is opened further, since the cover is further away from the pouring stream.
  • the retaining tongue has a tongue tip that corresponds to the highest point of the sealing ring.
  • the tongue-like shape with a raised tongue tip enables the sealing ring to be easily removed from and inserted into the pouring opening when opening or closing. It is advantageous if the holding tongue can be elastically deformed when it is pressed against the open edge of the pouring opening.
  • the increase in height is stepless on both sides of the tongue tip.
  • the retaining tongue can slide into and out of the pouring opening without getting caught on the open edge of the pouring opening.
  • the holding tongue along the circumference of the sealing ring has a length which is defined in that the holding tongue includes an opening angle with the center point of the cover which is between 90 and 40 degrees, preferably between 80 and 50 degrees particularly preferably between 70 and 60 degrees.
  • the claimed length of the retaining tongue enables the retaining tongue to be sufficiently stable so that it does not move in the second open position. ben.
  • the holding tongue is sufficiently flexible that it can be moved in and out of the pouring opening with little effort when the lid is pivoted around the joint.
  • the invention is preferably characterized in that the retaining ring and the lid in the first open position enclose a first angle of inclination between 180 and 220 degrees and preferably between 190 and 210 degrees and that the retaining ring and the lid in the second open position have a second angle of inclination between 70 and 90 degrees and preferably between 75 and 95 degrees.
  • the cover can be fixed at angles of inclination which differ significantly from one another. This allows the hinged lid to be adapted to the current level of the container. This significantly simplifies the handling of the container, in particular when pouring out.
  • the sealing element is a cover surface with a shoulder offset in the direction of the retaining ring. Due to the inwardly offset cover surface, the shoulder forms a stable sealing surface which remains stable in the event of a radial contact pressure from the inner wall of the container neck and forms a defined sealing surface. As a result, the pouring opening can be closed particularly tightly by the cover.
  • the sealing element can also be a sealing ring oriented in the direction of the retaining ring. This embodiment is suitable for applications which place less stringent requirements on the tightness of the container closure.
  • At least one driver element is formed on the cover in the direction of the retaining ring and is received in a corresponding recess provided on the retaining ring when the cover is in the closed position.
  • the interaction of the driver element with the recess causes a reliable Verrehsi assurance of the cover against the retaining ring.
  • the guarantee bars are reliably protected from being accidentally torn off during the initial rotating connection of the container closure to the container.
  • the driver element expediently has a ramp shape and has a step side and an inclined side. This sawtooth-like configuration of the driver element has the effect that the anti-twist device acts in the direction of the first opening of the container closure. If twisted in the opposite direction, the guarantee bars break.
  • the first extension is realized by a groove formed on the retaining ring
  • the second extension is realized by a vorsprin ing lid edge and the lid edge latches in the first Offenpositi on in the groove.
  • the first and second extensions enable secure locking in the first open position.
  • the extensions can be molded with little effort using the injection molding process and are easy to demold. It is preferred if the Hal teb suitable are biased in the second open position. As a result, the cover can be held in the groove on the edge of the cover without wobbling, without the cover folding back from the first open position.
  • the first extension has a gap with an indentation
  • the second extension has a transverse bar and the transverse bar engages in the indentation in the first open position.
  • the crossbar comes to rest on the indentation when the first extension is locked in the second extension. Since the crossbar has to be pressed over the indentation when it is engaged and disengaged, the cover is kept particularly stable in the first open position in this embodiment.
  • the hinge is formed by a first and a second hinge band and the first extension is formed between the first and the second hinge band.
  • the stability of the joint can thereby be improved and the retaining straps can be pretensioned in the first and / or in the second open position.
  • At least one tearable guarantee web connects the upper edge with the lid before the first opening on the circumference of the upper edge of the retaining ring. This means that it can be seen immediately whether the container closure is originally closed or has already been opened.
  • the container closure can be pushed onto a container neck of the container.
  • the container closure can therefore be connected to the bottle neck mechanically and accordingly quickly on a conveyor belt. Because the container closure is manufactured in one piece, the container closure can be mass-produced quickly and inexpensively in an injection mold.
  • the container closure is advantageously made from polypropylene. As a result, the retaining tongue can be elastically deformed when it is pivoted from the second open position into the closed position.
  • the retaining ring has slots distributed over the circumference with an upper edge and a lower edge, the upper edge being formed by an arcuate section of the retaining ring and the lower edge being formed by a wall section inclined inward in the radial direction and the lower edge of each slot forms projections, whereby engagement means are formed for a positive engagement with an annular projection on the outside of the container neck. Since the engaging means in the form of the inwardly inclined wall sections are not fully available on the retaining ring and there are also slots, the shape of which further reduces the use of material, the material requirement for plastic can be significantly reduced by up to 5%.
  • the wall section cannot be moved inward in the radial direction, as a result of which the retaining ring is held on the annular projection and can only be pulled over it when the retaining ring is stretched along its circumference.
  • the retaining ring is held so firmly on the annular projection by the wall sections that the predetermined breaking elements tear safely before the retaining of the wall sections is overcome.
  • the wall sections are flexible or movable. As a result, the wall sections can be removed from the injection mold or the injection molding tool with little effort.
  • the application force for bouncing on the closure cap is significantly reduced compared to the prior art.
  • An expansion of the guarantee ring which can lead to permanent damage to the closure cap, is largely prevented during demoulding and bouncing.
  • the wall sections therefore act in the manner of barbs.
