Definitions

  • the invention relates to a container closure made of plastic with a pivotable lid, which is articulated via at least one hinge connection from the lid closed position into a lid open position on a lid holder that can be placed on the container or the container itself, one additionally on the lid on the one hand and the Lid holder or the container itself, on the other hand, engaging spring is provided, which is arranged with respect to the lid pivot axis defined by the hinge connection so that the lid by the bias of the spring when pivoting from its closed position into the open position after passing through a dead center position in the opening direction is pushed.
  • Such container closures made of plastic, in which the actual lid is pivotally articulated via a hinge connection, which is preferably formed by at least one film hinge, to a lid holder mounted on the neck of the container, are, because of their inexpensive manufacture, to a large extent as a closure for - for example for receiving of liquid detergents, household cleaners or the like. certain - containers spread.
  • the opening position of these container closures is not exactly defined, i.e. the exact angular position in which the lid is relative to the lid holder due to the spring action in the open position cannot be exactly predicted, but rather closures sprayed off in the same injection mold if different batches of the plastic starting granulate are used, they turn out differently due to different elastic properties or different cooling speeds etc.
  • the exact opening position of a container closure can be very important. If the container to be provided with the closure is to be automatically filled and closed in large quantities in corresponding automated systems, filling or dispensing pipettes automatically having to be inserted and withdrawn again through the opened lid, it is important that the opened lid is a has a defined position.
  • the invention has for its object to provide a container closure of the type in question, the lid of which is pivoted by a spring arrangement when opening after exceeding a certain opening angle in a precisely defined, predetermined opening position.
  • this object is achieved according to the invention in that at least one integrally attached stop element in the form of at least one each of the cover on the one hand and one associated therewith, each on the pivotable cover and on the cover holder or the container itself the lug holder or the container itself, on the other hand, is provided with the protruding projection which, in a predetermined lid opening position, has abutment surfaces which come into contact with one another and are pressed against one another by the spring acting on the lid Closing the cover from an open position lying beyond the intended open position by the respective cooperating approach on the other pivotable part when approaching the intended open position g is elastically pushed aside and, after reaching the open position, springs back into its intended stop position with the abutment surfaces pressed against each other.
  • the hinge connection is preferably formed by at least one film hinge integrally connecting the lid and the lid holder or the container.
  • the spring is an integrally attached spiral spring on at least one of the parts of the container closure pivotally connected to one another via the hinge connection.
  • the configuration is such that at least one of the stop surfaces is or are formed on the underside of a hook-shaped angled portion of the extension or the extensions.
  • 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 the attachment provided on the lid can then be made stiffer.
  • the lug provided with the hook-like bend or the lugs then expediently have an area on the upper side of the bend opposite the stop surface, at least in the area which comes into contact with the associated lug on the other of the parts which can be pivoted relative to one another when closing from the beyond the intended opening position with the respectively assigned lug rounded contour, which promotes the stepping away of the stiffer extension over the elastic with the angled extension and its elastic bending without risk of damage to the extensions.
  • the lug or the lugs not provided with the bend can also have a rounded contour in their position when the cover is closed from the position beyond the intended open position with the respectively assigned end section coming into contact with the bend provided.
  • the stop surface (s) formed on the underside of the bend (s) expediently then run essentially at right angles to the bending plane of the associated elastically bendable extension, since this ensures that the stop surfaces pressing against one another in the open position Preload force of the spiral spring has no force component that tries to disengage the stop surfaces by elastic deformation of the elastic lugs.
  • the projection protruding from the lid can be shaped so that it has a high bending resistance, while the projection protruding from the lid holder or the container itself is designed to be elastically bendable, the cooperating stop surfaces formed on the projections being arranged in this way that a force exerted on the cover in the sense of a force that is to be pivoted further in the opening direction beyond the predetermined cover opening position in the abutting abutment surfaces is essentially perpendicular to the Abruptly creates reaction force. Since this reaction force is normal to the stop surfaces, it cannot cause the elastic attachment to bend, so that even an inadvertent pivoting of the cover beyond the intended opening position is not possible.
  • the projection protruding from the lid is expediently provided with at least one rib stiffening it against bending and at its end facing away from the lid with a short projection supporting the stop surface, the projection protruding from the lid holder or the container itself being in the form of two spaced apart, transverse has to its longitudinal extension bendable rod-shaped sections, the free ends of which are connected by a crosspiece, on the underside of which the stop surface is formed.
  • the clear distance measured between the rod-shaped sections of the projection projecting from the cover holder or the container itself is then expediently dimensioned approximately the same or slightly larger than the width of the projection of the projection projecting from the cover.
  • the stop surfaces held against one another in the open position are arranged such that a desired opening angle the lid is adhered to exactly. Opening angles are preferred in which the cover is folded up in relation to its fully closed position in the intended opening position by an angle between 80 ° and 100 °, preferably by 90 °.
  • the stopper-like extension preferably has the shape of an annular wall which is of slightly spherical design on its outer contour, at least in a partial region, the through opening being formed in an annular wall in the cover holder, the inside diameter of which is clear with respect to the outer diameter of the spherical partial region of the annular wall forming the stopper-like extension the cover is dimensioned with a slight oversize. In the closed position of the cover, a hermetic closure of the through opening in the cover holder is thus ensured by the plug-like extension.
  • the spherical ring wall closes the passage opening in the lid holder to a sufficient extent against evaporation of liquid contained in the container when the lid is not completely closed, but is only folded down onto the lid holder. Since the lid is pressed onto the lid holder via a spring, an adequate closure against evaporation can be achieved in this way.
  • the tilting lid is only folded down, for example during transport between individual processing stations, in order to avoid evaporation of the container contents, while keeping the opening force required for the subsequent opening of the lid in a subsequent station as low as possible .
  • the end section of the ring wall provided on the cover holder facing the cover expediently widens in the direction of its free end in order to facilitate the insertion of the plug-like extension when the cover is closed.
  • the clear diameter of the holder-side ring wall or the passage opening is dimensioned sufficiently large for the insertion of laboratory pipettes and / or elongated tube-like filling elements.
  • the inside diameter should be at least 8 mm, preferably at least 10 mm.
  • Polyethylene, polypropylene, polyoxymethylene, polyethylene terephthalate, polybutylene terephthalate and styrene-butadiene copolymers come into consideration as thermoplastic plastics for the production of the container closure according to the invention, with the use of polypropylene being currently preferred.
  • the spiral spring in the after solidification in the Associated injection mold in the unstressed state the shape of an arcuate leaf spring, one end of which is integrally molded on the lid and the other end of which is integrally molded on the lid holder or the container itself, the leaf spring preferably extending over an arc of approximately 180 ° in the unstressed state .
  • the arc of the leaf spring is directed with respect to the lid pivot axis so that a lid pivoting movement in the lid closing direction reduces the curvature of the arc at least in a first section of the closing movement.
  • the leaf spring then strives to bend back into the arcuate shape, whereby the cover is urged into the intended opening position until the stop elements abut against one another.
  • spiral spring instead of a spiral spring, it can also be divided into two laterally spaced spiral springs which are arranged at the same distance on opposite sides of a vertical plane of symmetry through the container closure at right angles to the lid pivot axis.
  • the leaf spring (s) has an average radius of approximately 1.2 mm, a thickness of approximately 0.4 mm and a width of has a total of about 3 mm.
  • the spiral spring is in the form of an angle piece made of two substantially planar, integrally connected angle arms which are integrally connected to one another along a common edge, the free edges of which lie opposite the common integral edge, each integrally on the lid or on the lid via a film hinge Lid holder or the container itself are injection molded.
  • the exemplary embodiment of a container closure according to the invention shown in its entirety with 10 in FIGS. 1 to 6, is an integral injection molded part made of plastic, which consists of two interconnected main components, namely a lid holder 12 which can be tightly attached to an associated container (not shown) and which can be pivoted assembled on the lid holder 12 hinged lid 14.
  • the container closure 10 is intended for containers which are approximately square in horizontal section and which taper on the top side like a bottle to a cylindrical mouth opening via a transition section which is reduced in their external dimensions for snapping on the lid holder 12.
  • the square cross section of the actual container was chosen in a special case in order to be able to assemble or assemble the containers into larger containers in a space-saving and immovable manner, whereby due to the flat contact of the container walls that adjoin one another laterally and in rows, there is also a defined distance between them adjacent or front and rear adjoining container openings is given in the assembled containers.
  • the special design of the container is not the subject of the present invention, which is why the description of the design of the container in the present context can be dispensed with.
  • the lid holder 12 which is open on the underside for placement on the reduced area of an associated container, has essentially vertical side walls 16, 18, a rear wall 20 and a front wall 22, which are closed on the top by an essentially flat top wall 24 .
  • a ring wall 26 which is circular in plan view and which forms a stopper which is open on the underside and which is pressed into the mouth opening of the lid holder on the associated container.
  • ribs 28 appearing at the lower end of the container guide the cover holder 12 during assembly on the associated container so that the ring wall 26 is automatically aligned with the container mouth when it is attached and after assembly, the lid holder 12 is secured against horizontal displacement on the container.
  • a further, essentially cylindrical ring wall 32 projects from the top of the top wall 24, the diameter of which is smaller than the diameter of the ring wall 26 to be mounted in the mouth of the container.
  • the top wall is interrupted, i.e. the annular wall 32 now represents the continuous mouth of the container provided with the container closure 10 for the introduction of pipettes or nozzles.
  • the essentially cylindrical inner surface of the ring wall 32 widens conically at 34 and thus an entry slope for a ring wall 36 - which will be described later on from the cover 14 and engages in the clear interior of the ring wall 32 trained plug approach of the lid 14 forms.
  • the cover 14 has a flat cover wall 38 which is essentially delimited correspondingly to the cover wall 24 of the cover holder 12, the edges of which are assigned to the side walls 16, 18 and the front wall 22 of the cover holder 12 in strip form Wall sections 40, 42 and 44 step towards the lid holder, the free edges of which sit in the closed position of the lid 14 (FIGS. 4 and 5) on the top wall 24 of the lid holder 12 and thus form stop surfaces for the lid closed position.
  • the cover wall 38 protrudes slightly beyond the wall section 44 in a central area.
  • the protruding flap 38a formed in this way serves as a handle for opening the cover 14.
  • the ring wall 36 forming the sealing plug engages in the ring wall 32 of the cover holder 12.
  • a part of the ring wall 36 which is slightly spherical in its outer contour rests against the ring wall 32 under elastic prestress and thus seals the inside of the ring walls 32 when the cover 14 is completely closed and 26 of the lid holder 12 formed passage into the interior of the container hermetically against leakage of the container contents from the sealed container. If, on the other hand, the lid 14 is only folded down onto the lid holder 12, a seal which sufficiently prevents the evaporation of liquid contained in the container is still obtained.
  • film hinges 50 are formed from the plastic material of the container closure in the region of the rear wall 20 between projections 46 emerging from the top wall 24 of the lid holder 38 and from the underside of the lid wall 38, which pivot the Lids 14 from the position illustrated in FIGS. 3 and 4, in which they are formed when sprayed in the injection mold, enable the closed position shown in FIGS. 4 and 5.
  • the lid 14 and the lid holder 12 are thus connected to form an integral unit via the film hinges 50.
  • there is a further integral connection by means of two laterally spaced, laterally spaced bending springs 52, which are also injection molded in the rear wall area of the lid holder 12 and the associated edge of the lid wall 38.
  • These bending springs 52 are formed in the injection mold, the wall thickness of which is significantly greater than that of the very thin ones Film hinges 50 is, in the approximately semicircular curved shape shown in Fig. 3.
  • the arc and the position of the spiral springs 52 is selected with respect to the position of the film hinges so that the spiral springs 52 are bent when they are swiveled up from the position shown in FIG. 3 and thereby stretch and then assume an extended position in an intermediate position. Due to the elastic bending, the spiral springs 52 develop a restoring force which tries to push the cover back into the starting position.
  • the arrangement of the film hinges 50 and the spiral spring 52 is also selected so that the restoring force generated by the spiral spring when closing is in the closed position of the cover is minimized, or that - after pivoting the cover through a dead center position - the restoring force acts on a lever arm with respect to the cover pivot axis formed by the film hinges, which generates a moment acting in the closing direction.
  • the cover is then held in the closed position not only by the friction of the plug-like ring wall 36 in the ring wall 32, but also by an additional closing moment.
  • the lid 14 After assembly of the container closure 10 on the associated container, the lid 14 should - for the reasons described at the outset - be held in an intended opening position when opened, which is the position shown in the exemplary embodiment shown in FIGS. 1 and 6c, relative to the closed position by 90 ° may be swung up position.
  • This is achieved in the closure according to the invention in that cooperating stop elements are provided on the lid holder 12 and the lid 14, which admittedly allow the lid 14 to be pivoted out of its production position into the closed position, but are then effective in the intended open position when pivoting back again from the closed position become.
  • Both lugs 54 and 56 are functional parts integrally molded from the material of the container closure, preferably at least one of the lugs 54, 56 being dimensioned such that it can be elastically bent.
  • the surface of the bend opposite the actual stop surface 60 is rounded in such a way that the free end of the extension 54 slides on this rounded upper side like on a cam surface and can also bend the extension 56.
  • the free end of the extension 54 is also rounded accordingly.
  • the position of the stop surface 60 and the stop surface 62 formed on the flat side opposite the rounding of the extension 54 is now selected such that the cover 14 after spraying in the shape of the shape shown in FIG 6a can be pivoted upwards, whereby it comes to rest against the rounded upper side of the bend 58 before the intended opening position is reached (FIG. 6b).
  • FIGS. 7 to 10 basically corresponds in construction and function to the container closure 10 described above, so that it is sufficient to describe only the modifications and further developments made below, while for the corresponding configurations Reference can be made to the preceding description of the container closure, especially since functionally identical components of both container closures in the drawings are assigned the same reference numerals, each of which is preceded by a "1" in the container closure 110.
  • the front surface 122 of the lid holder 112 which is no longer flat on the front, but rather - in the plan view of the top wall 124 - is limited to a circular arc, which merely represents an adaptation to another shape of the associated container (not shown)
  • the mouth 132 in the cover wall 124 of the cover holder 112 is not in one of the projecting annular wall 32 Ring wall, but formed as a flush opening in the top wall 124 into which the ring wall 136 forming the sealing plug engages on the underside of the top wall 138.
  • a tube extension 137 which surrounds the mouth 132 and projects into the interior of the container and which therefore immerses in the liquid filled in the container and thus reduces the surface area of the container filling which is exposed to the ambient air when the lid 114 is open, thereby reducing the possibility of chemical changes to the container filling due to oxidation or the like.
  • a spiral spring 152 is provided in the container 110, which is arranged centrally between the film hinges 150 and which, instead of the circularly arched spiral spring 52 in the untensioned state arising in the injection mold (FIGS. 9 and 10), has the shape of one of two has at an angle to each other extending angle arms 152a, 152b composite angle piece.
  • the free ends of the angle arms 152a, 152b are not rigid, but are integrally connected to the cover wall 138 or the rear wall 120 of the cover holder 112 by means of film hinges 152c, 152d. It has been shown that opening and closing forces can be generated with a bending spring designed in this way in the form of an angle piece, which ensure that the cover 114 is secured in the desired closing or opening position.
  • FIGS. 11 and 12 show a third exemplary embodiment of a container closure 210 which has been modified with respect to the described container closures 10 and 110 with regard to the design of the approaches which secure the lid in the intended lid opening position against further opening, of which only the changes made are described below , while reference can be made to the preceding description with regard to the configuration corresponding to the exemplary embodiments already described, especially since functionally the same parts in the drawing figures 11 and 12 are assigned the same reference numerals as the first exemplary embodiment, which are only preceded by a "2".
  • the projection 254 protruding from the cover wall 238 of the cover 214 is stiffened by two oblique ribs 254a, 254b molded onto its edge area in such a way that it is practically rigid.
  • the stop surface corresponding to the stop surface 60 of the extension 54 of the container closure 10 is formed here on a projection 259 which is reduced in width and which protrudes from the boundary edge of the extension 254 facing away from the cover.
  • the elastically bendable extension 256 which corresponds functionally to the extension 56 of the first exemplary embodiment, here has two laterally spaced sections 256a, 256b projecting from the top wall 224, on the free ends of which are connected by a transverse web 258, which thus replaces the hook-like angled portion 58 of the first exemplary embodiment , and on the underside of which the associated stop surface is formed.
  • the tops of the projections 254 or of the crosspiece 258 opposite the stop surfaces are rounded off, so that again the effect already described occurs that when the cover 214 is pivoted out of the injection mold into the closed position, the rounded surfaces mentioned come into contact with one another and then a component the closing force exerted on the cover 214 arises, which bends the rod-shaped sections 256a and 256b, so that the crossbar dodges and the projection 259 can pass over the crossbar 258.
  • the rod-shaped sections 256a, 256b spring back and the abutment surfaces mentioned on the two lugs come into contact with one another.
  • the - preferably provided - film hinges could also be dispensed with if such a defined pivot axis is created by designing other functional components articulating the cover part on a defined pivot axis on the cover holder.
  • swivel pins molded onto the cover or the cover holder would be conceivable, which, after spraying, are snapped into associated pin receptacles in the other part.
  • this design requires an additional assembly step for locking the pins in the associated recesses, the use of film hinges is preferred.
