Definitions

  • the invention relates to a container with a safety closure, in particular for holding pharmaceutical preparations or chemicals, certain containers made of glass, metal or plastic, which optionally can be pressed through a closure plug which can be pressed into the interior of the mouth of the tubular container neck and which has a handle plate which limits the insertion path and serves to grip the closure plug can be closed or opened to remove the filling material.
  • Containers with safety closures are used in particular to hold potential harmful or toxic substances, ie chemicals, cleaning agents, cosmetics, pharmaceuticals and the like, which must be kept away from children.
  • the containers are therefore not only intended to properly store the fillers, but also preventively prevent small children from opening the container and being able to suffer damage to health by enjoying or touching the contents of the container.
  • the removal of the container contents must be authorized and carried out via the
  • the function of the safety lock should be easily and quickly possible for the person who is informed, so that the lock is actually used and is not put aside after first use or replaced by a simple, manageable ordinary lock. Since the safety locks are essentially used to protect children, they are also referred to as "child-proof locks" (KgV).
  • screw closures for pharmaceutical bottles
  • the screw closure consists of the actual screw cap and a rotary cap that overlaps the screw cap, which is forced into a position by resilient elements in which it has no engagement with the screw cap when it is rotated in the opening direction , ie turns empty, so that the bottle remains closed by the screw cap.
  • the rotary cap can be pressed against the action of the spring elements mentioned in a position coupled to the screw cap, so that then rotation of the cap in this pressed position also allows unscrewing the actual screw cap.
  • closures with non-positively held plugs have already been designed to be childproof in that the closure plug inserted into the container is designed in this way was that it can not be grasped directly by hand, an insertion opening being provided in its head plate for a tool suitable for extraction.
  • This tool is integrally molded on a locking ring molded onto the sealing plug and connected to it by easily breakable webs, which in this case also represents a so-called tamper-evident device (DE-PS 20 35 747).
  • This closure has proven itself in its security function. It is perceived as a disadvantage, however, that the locking ring with the molded tool is no longer connected to the closure after the container has been opened for the first time and can therefore be lost.
  • the invention is therefore based on the object of providing a container with a safety closure designed as a stopper closure, which can be opened and closed without difficulty by a person who is informed about the closure function, without the need for a separate tool, the usual, previously unsecured closure of, for example Stopper serving tablet tubes should continue to be applicable.
  • this object is achieved according to the invention in that a cylindrical securing sleeve projecting over the end face of the container neck is arranged on the outside of the container neck, the projecting region of which surrounds the peripheral surface of the handle plate of the sealing plug in the container closed position, the bottom of the handle plate facing the container mouth resting on an annularly closed radial surface of the securing sleeve, that the securing sleeve and the container mouth are in complementary thread engagement with one another over a limited path in the opening direction of the sealing plug and then secured against axial separation from one another and that the securing sleeve has at least one protrusion directed radially inwards from the inner surface, which is latched to the outer surface of the container neck via a first annular bead which is directed radially outward in front of it in the opening direction.
  • the protruding area of the securing sleeve thus prevents the grip plate of the sealing plug from gripping, so that it is first secured against being pulled out of the container mouth.
  • the locking sleeve When the locking sleeve is turned in the screwing-on direction, it is initially moved in the opening direction of the sealing plug by the existing thread engagement and the sealing plug is taken along.
  • the handle plate of the sealing plug is still inside the securing sleeve and is therefore not accessible, so that the sealing plug can still not be gripped. Only when the locking sleeve is now deliberately screwed back in the direction of rotation, does the grip plate of the sealing plug emerge from the locking sleeve and the sealing plug can then be removed.
  • a second radially outwardly directed annular bead is provided at a distance from the first annular bead to the mouth of the container neck which is at least equal to the axial thickness of the grip plate and on which the radially inward projection of the securing sleeve is provided after snapping away over the first ring bead comes to rest when the locking sleeve is turned in the unscrewing direction.
  • the radially inward projection of the securing sleeve is also expediently designed as a circumferential, closed annular bead.
  • the design is expediently such that the radially inward projection of the securing sleeve in the container-side end region of the securing sleeve opposite the container mouth and the threaded sections of the securing sleeve and the container neck which are in complementary thread engagement are offset in the axial direction of the container mouth on the outside of the container neck or . are provided on the inside of the securing sleeve.
  • the second annular bead on the container neck has a cross-section which is increasingly wedge-shaped from the container mouth towards the actual container and which has a substantially radially extending edge on its side facing away from the container mouth is limited. If the radially inward projection of the securing sleeve has a cross-section which is complementary to the second annular bead of the container neck, then the wedge surfaces of the annular beads can slide on one another during the first assembly and step over one another with elastic expansion of the securing sleeve, during an axial disassembly of the securing sleeve the radial surfaces of the ring beads that come into contact with one another are then no longer possible.
  • the securing sleeve is therefore expediently made of an elastically expandable material, and preferably - like the sealing plug - by injection molding from plastic.
  • the threaded sections of the securing sleeve and the container neck are preferably provided with multi-start complementary threads, which can then have a relatively strong thread pitch.
  • the rotation required to generate the required opening stroke of the securing sleeve can thereby be limited to approximately half a turn of the securing sleeve.
  • the axial extent of the threaded sections of the securing sleeve and the container neck and the distance of the second radially outwardly directed annular bead provided on the container neck from the first 'annular bead can be dimensioned such that the threaded section of the securing sleeve when turning in the screwing direction can be screwed in front of the threaded section of the container neck and then freely rotated on the container neck.
  • the locking ring can thus be turned freely in the fully screwed-up position in both directions, the handle plate of the sealing plug still being received in the locking sleeve, ie not being grasped.
  • the part of the sealing plug which engages in the container mouth can either be designed as a sealing olive which is dimensioned with an oversize in relation to the clear cross section of the container mouth, or it becomes a cylindrical one which is dimensioned with respect to the clear cross section of the container mouth with an undersize Plug part formed, which then seals with molded radially projecting sealing lamellae in the container mouth.
  • the sealing plug can also be provided in a manner known per se with a hold-down device which can be compressed in the axial direction or also with a drying insert.
  • the peripheral surface of the handle plate and / or the peripheral surface of the securing sleeve, which is used to open and close the sealing plug, is or are expedient with knurled ribs or the like. provided that can be injection molded in one piece with the manufacture of plastic by injection molding.
  • the securing sleeve In order to facilitate the manipulation of the securing sleeve even by people with reduced hand forces, for example due to gout or rheumatism, it is advisable to provide the securing sleeve with an outer circumferential surface that preferably has a circular shape that deviates from the circular shape along its longitudinal central axis has a polygonal or polygon-like boundary. Due to the polygonal design, the locking ring is easy to grip and the lever arm, on which the torque acts, is enlarged in the area of the polygon corners compared to a cylindrical locking sleeve, ie o with the same torque, a higher or. a lower torque generates the same opening torque.
  • polygonal securing sleeve can also be held with aids - for example by clamping it in a drawer gap - and the opening force can be exerted on the container, which, with the appropriate shape and size, is even easier to grip and can be rotated relative to the securing sleeve with lower forces.
  • the stopper part of the closure has a cylindrical circumferential surface or the shape of a sealing olive
  • the ring bead on the stopper part has the task of sealing the inside of the container against the ingress of ambient air.
  • This seal is further improved if the inside diameter of the container neck is dimensioned somewhat smaller in the area adjoining the annular bead in the direction of the inside of the container with an area located in comparison to the inside diameter of the area in front of the annular bead on the mouth side.
  • the embodiment shown in the drawing figures of the container according to the invention, designated in its entirety by 10, with a safety closure is a tablet tube 12, which is closed by a customary stopper 14, which is pressed into the open mouth of the tablet tube.
  • the sealing plug 14 has the shape of an olive-shaped plug part 18 provided with a knurled or longitudinally ribbed grip plate 16, from the hollow interior of which protrudes a hold-down element 12 which can be elastically pushed back in the axial direction.
  • the tablet tube 12 is provided at its closure-side end with a neck portion 22 somewhat drawn in relative to the remaining tube outer diameter, on which a securing sleeve 24 molded from plastic and longitudinally ribbed on its cylindrical outer surface is placed, the outer diameter of which corresponds approximately to the outer diameter of the tablet tube 12.
  • the neck section 22 of the tablet tube 12 carries, in its area immediately adjacent to the mouth, a threaded section 26 provided with a multi-start thread, to which a complementary threaded section 28 in the interior of the securing sleeve 24 corresponds.
  • the securing sleeve 24 protrudes by the measure of the thickness of the grip plate 16 of the closure plug 14 over the mouth of the neck portion 22, whereby it fits the circumferential surface of the grip plate 16 so that the grip plate circumference cannot be grasped by hand.
  • the rear surface of the handle plate facing the tube mouth lies in its outer edge region on a circumferential radial ring surface 30 in the securing sleeve, so that the handle plate l6 and thus the plug 14 are positively entrained when the locking ring is axially displaced away from the tube mouth, while at an inevitable displacement of the securing sleeve does not result in such inevitable taking.
  • the neck section 22 is axially with two Provided at a distance from one another are provided circumferential annular beads 32, 34, of which the first annular bead 32 lies just above the steps of the neck portion formed at the transition from the neck section to the full diameter of the tablet tube, while the second annular bead 34 corresponds to at least the measure of the thickness of the grip plate 16 Distance above the first annular bead 32 is arranged.
  • An annular bead 36 protruding radially inward from the inner surface of the securing sleeve 24 from under the inner surface engages under the first annular bead 32 of the neck portion 22 when the tablet tube is closed.
  • the securing sleeve 24 can be screwed axially upward as a result of the engaged threaded sections 26, 28, but some force is required at the beginning of the screwing-on process to elastically widen the lower end of the securing sleeve over the first annular bead 32 To snap neck portion 22 away.
  • the screwing-on process can then be continued until the ring bead 36 abuts the second ring bead 34 on the neck section 22, only the force holding the stopper part 18 in the mouth of the tablet tube, which is considerably less than the aforementioned unlatching force, having to be overcome.
  • the sealing plug 14 When turning the securing sleeve in the screwing-on direction, the sealing plug 14 is taken along on the handle plate 16 and the plug part 18 is at least partially pulled out of the container mouth. Then the locking sleeve is in again Screwed in the opposite direction until its ring bead 36 is locked behind the ring bead 32, the sealing plug remains in the pulled-out position and the then exposed handle plate can be gripped and the sealing plug can be pulled out completely. No unusual manipulations are then required to close the tablet tube, but the sealing plug is simply pressed into the open end of the securing ring and thus into the mouth of the tablet tube in the usual way.
  • the safety function of the safety lock designed in the manner according to the invention is therefore based on the fact that the sealing plug, which is normally inaccessible because of the concealed position in the safety sleeve, has to be brought into a position in which its grip plate is accessible by means of two opposite screwing operations of the safety sleeve At the beginning of the first screwing process, an unlatching force, which is not usual with screw caps, has to be exerted on the securing sleeve, which is at least not exerted by small children if they are not clear about the locking function.
  • the second annular bead 34 provided on the neck portion 22 of the tablet tube 12 and the annular bead 36 of the securing sleeve 24 are expediently designed with a complementary wedge-shaped cross section (FIG. 4) in such a way that the wedge surfaces during the screwing-in process - while expanding the securing sleeve - slide on one another, while during the screwing-on process, radially running end faces of the ring beads come to rest against one another, which prevent the securing sleeve from being completely unscrewed over the second ring bead 34.
  • the cross-section of the first annular bead 32 is expediently chosen such that the securing ring can be unscrewed, even if only with a correspondingly increased release resistance.
  • the surface of the first annular bead 32 which is intended to prevent the disengagement of the annular bead 36 when the securing sleeve is unscrewed is therefore advantageously not designed to be radially, but rather inclined or rounded at an angle in the direction of rotation.
  • the securing effect can be increased further if the axial length of the threaded sections 28, 26 on the securing sleeve 24 or on the container neck 22 is relatively short and the distance of the second radially outwardly directed annular bead 34 provided on the container neck from the first annular bead 32 is measured somewhat longer , since the threaded section 28 of the securing sleeve 24 can then be screwed when rotating in the screwing-on direction up to the threaded section 26 of the container neck and can then be freely rotated on the container neck without the sleeve being given an axial movement component.
  • the handle plate 16 is still countersunk in the securing sleeve 24, ie the sealing plug cannot be gripped either.
  • the modified container 110 shown in FIGS. 5 to 7 largely corresponds to the container 10 described above with regard to the function of the safety lock and the same parts are identified by the same reference numerals with the prefix "1". To avoid unnecessary repetition, it is therefore sufficient to describe only the changes made here, while reference can be made to the preceding description for the corresponding design features.
  • the container 110 is designed as a square vial, for example made in a blow molding process from plastic, which may serve to hold medication.
  • the securing sleeve 124 as can best be seen in FIG.
  • the distance R from the longitudinal central axis of the securing sleeve to the Corners of the triangle is greater than the distance r from the longitudinal central axis to the center of one of the triangular sides, that is, the torque exerted by a user when the securing sleeve 124 is screwed onto a corner of the securing sleeve acts on the comparatively longer lever arm R, that is to say with the same torque achieved a larger torque.
  • the plug part 118 of the sealing plug 114 is - in contrast to the plug part 18 designed as a sealing olive for the container 10 - cylindrical and has a radially circumferential annular bead 140 as the sealing element.
  • a radial annular bead 142 is assigned to the annular bead 140 in the interior of the container neck 122, via which the annular bead 140 snaps away when the sealing plug 114 is fully pressed in in the prescribed manner when it is pressed into the container neck 122.
  • the resulting snap noise also indicates when the closed position has been reached.
  • the area of the clear neck opening below, ie in the direction of the inside of the container at the ring bead 142 has a somewhat smaller diameter than the area lying in front of the ring bead, so that the ring bead 140 of the stopper part with higher tension in the fully depressed position of the stopper bears on the inner wall of the container neck and seals, as in a press-in position, in which it is still above the annular bead 142, where the tension is only so great that the Stopfenteilll4 just with little friction in Container neck 122 is held and therefore does not accidentally fall out when the container 110 is turned upside down.
