Definitions

  • the invention relates to a container closure made of plastic with a pivotable Lid that has at least one hinge connection from the lid closed position in a Lid opening position pivotable on a lid holder that can be placed on the container or the container itself is articulated, in addition one on the cover on the one hand and the lid holder or the container itself on the other hand engaging spring which is with respect to the lid pivot axis defined by the hinge connection is arranged so that the cover by the bias of the spring Swiveling from its closed position into the open position after passing through one Dead center position is pushed in the opening direction.
  • Such container closures made of plastic, in which the actual lid via a hinge connection, which is preferably formed by at least one film hinge is pivotally articulated on a lid holder mounted on the neck of the container are, due to their inexpensive manufacture, to a large extent as a closure for - e.g. for taking up liquid detergents, household cleaners or the like. certain - Containers spread.
  • the opening position is with these container closures not exactly defined, i.e. the exact angular position in which the lid due to the Spring action in the open position relative to the lid holder is not exact predictable, rather, closures can even be hosed in the same injection mold when using different batches of the plastic starting granulate due to different elastic properties or different cooling speeds etc. turn out differently.
  • exact opening position of a container closure can be very important. If that with the container to be provided automatically in large quantities in appropriate automated systems are to be filled and closed, whereby through the open Lid automatically retracted filling or removal pipettes and again must be withdrawn, it is important that the open lid is a defined one Position.
  • the invention has for its object a container closure of the question here To create type, the lid by a spring arrangement when opening after exceeding a certain opening angle in a precisely defined, predetermined opening position is pivoted.
  • At least one of the approaches is preferably so elastic trained that he when the lid is closed for the first time beyond the intended Open position lying through the position with him interacting approach to the other pivotable part when approaching the Intended opening position is elastically pushed aside and after reaching the open position in its intended stop position with each other in System springs back against the thrust.
  • This makes it possible to close the container cheap to produce by injection molding in an injection mold in which the lid the container closure is sprayed into a position open by 180 °.
  • the Approaches provided stop surfaces during the closing process by elastic deformation at least one of these approaches overlap.
  • the hinge connection is preferably - as in the prior art - of at least a film hinge integrally connecting the lid and the lid holder or the container educated.
  • the configuration is such that at least one of the stop surfaces on the underside of a hook-shaped angling of the Approach or approaches is or are formed.
  • the elastically designed attachment or the attachments provided with the bend is or are then preferably provided on the lid holder or the container itself, so that then the approach provided on the lid are made stiffer can.
  • the approach or the approaches provided with the hook-like bend then point Appropriately on the upper side of the bend opposite the stop surface at least when closing from beyond the intended opening position with the respectively assigned approach on the other of the pivotable relative to each other Divide the area coming into contact with a rounded contour, which is the step away of the stiffer approach over the elastic with the bend Approach and its elastic bending here without any risk of damage that promotes approaches.
  • the stop surface (s) formed on the underside of the bend (s) run or then expediently run essentially at right angles to the bending plane of the associated elastically bendable approach, since this ensures that the stop surfaces on the Approaches in the open position of the pre-tensioning force of the spiral spring none Has force component, which tries to stop by elastic Deformation of the elastic approaches to disengage.
  • the approach protruding from the cover can do so in an alternative embodiment of the invention be shaped so that it has a high bending resistance during that of the lid holder or the projection protruding from the container itself is designed to be elastically bendable, the cooperating stop surfaces formed on the lugs being arranged in this way are that one on the lid in the sense of it over the predetermined lid opening position exercised further to be pivoted in the opening direction Force in the abutting abutment surfaces is essentially perpendicular to the Abruptly creates reaction force. Because this reaction force is normal runs to the stop surfaces, it can not bend the elastic approach cause so that even an accidental pivoting of the lid over the intended Open position is not possible.
  • the approach protruding from the cover is useful with at least one against it Bending stiffening rib and at its end facing away from the cover with a stop surface bearing short projection provided, the of the lid holder or the projection protruding from the container itself in the form of two spaced apart, has rod-shaped sections which can be bent transversely to their longitudinal extension, the free sections of which Ends are connected by a crossbar, on the underside of which the stop surface is formed is.
  • the between the rod-shaped sections of the from the lid holder or the clear distance measured from the container itself is then expedient about the same or slightly larger than the width of the projection of the lid dimensioned approach above.
  • an embodiment is preferred which the one another in the open position in abutment stop surfaces are arranged so that a desired opening angle the lid is adhered to exactly. Opening angles are preferred in which the lid in relation to its fully closed position in the intended Open position at an angle between 80 ° and 100 °, preferably folded up by 90 ° stands.
  • the plug-like approach preferably has the shape of at least on its outer contour in a partial area slightly spherical ring wall, the through opening is formed in an annular wall in the lid holder, the clear inner diameter with respect to the outer diameter of the spherical portion of the plug-like Approach-forming ring wall of the lid is dimensioned with a slight oversize.
  • the spherical ring wall already closes the through opening in the lid holder then to a sufficient extent against evaporation of liquid contained in the container, if the lid is not completely closed, but only folded down onto the lid holder is.
  • the tilting lid Since the lid is pressed onto the lid holder via a spring, in this way a sufficient seal against evaporation can be achieved.
  • Using of containers provided with such tilting lid container closures in The tilting lid becomes an automatic analyzer, for example, during transport between individuals Processing stations only folded down to avoid evaporation of the container contents, the opening force required for the subsequent opening of the cover in a subsequent station keep it as low as possible.
  • the end section facing the cover which is provided on the cover holder Ring wall expediently widens towards its free end for insertion the plug-like approach when closing the lid to facilitate.
  • the clear diameter of the bracket-side ring wall or the through opening is for insertion sufficient from laboratory pipettes and / or elongated tube-like filling organs large sized.
  • the inside diameter should be at least 8 mm, preferably be at least 10 mm.
