Definitions

  • the invention relates to a closure for an evaporation device according to the preamble of patent claim 1.
  • An evaporation device in which a container for volatile active substances can be screwed onto the underside, is known, for example, from the design M 91 07 753.2.
  • a cap is formed on a downward-facing surface, which is provided with an internal thread and serves to screw in a container such as a bottle or the like, which is provided on its bottle neck with a corresponding external thread.
  • the housing of the evaporation device which is constructed in two parts, for example, has locking and receiving devices for, for example, an electrical resistance above the screw cap.
  • the container is equipped with an insert which carries a central opening through which a wick or element extends which is inserted into the container and upwards is extended such that it extends through a corresponding opening within the cap into the housing, where the upper section of the wick-shaped element is surrounded by an electrically operated resistance element or the like.
  • the purpose of this device is to transport volatile active substances contained in the container upward through the wick-shaped element into the evaporation device in order to distribute the active substances there with or without the aid of an electrically effective resistance device.
  • a disadvantage of this device is that the container can be easily unscrewed from the housing when the evaporation device is used, i.e. No safety measures are provided to prevent the container containing the volatile active substances from being unintentionally unscrewed.
  • closures are basically known, ie screw caps, which admittedly allow bottles or the like to be screwed tightly, while opening the bottles can only be achieved if, for example, pressure is exerted, ie when the screw cap is pressed down against the bottle, the cap in Opening direction is rotated.
  • Such closures are constructed in such a way that they consist of an outer receiving part or cap, which is equipped on its bottom facing the bottle with tooth-shaped projections which are arranged at a predetermined radius from the center of the axis. One flank of these projections is chamfered, the other flank runs essentially vertically to the bottom of the receiving part.
  • An internally threaded closure part is inserted into the receiving part, which has star-shaped ribs on its bottom facing the bottom of the receiving part, such that these ribs can be brought into engagement with the projections. If the closure part is thus rotated in a first direction in which the locking ribs come into contact with the oblique flanks of the projections, the closure part being screwed firmly onto the bottle, the bottle can be together with the closure part rotate relative to the receiving part, ie the bottle remains closed, even if there is a relative rotation between the bottle and the receiving part. To open the bottle, on the other hand, it is necessary to press the receiving part in the direction of the closure part and to rotate it in the opposite direction to the above explanation. In this case, there is a locking between the receiving part and the closure part in that the locking ribs come into engagement with the vertical flanks of the projections, which enables the bottle to be opened.
  • the invention is based on the object of providing a closure for an evaporation device of the type mentioned in the introduction, in which an inadvertent removal of the container containing the volatile active substances is avoided.
  • the invention provides a closure for an evaporation device, which enables the container containing the volatile active substances to be removed only if special measures are taken during unscrewing.
  • a device is provided in the receiving part which generates a spring preload in such a way that the receiving part on the one hand and the closure part on the other hand are kept spaced apart.
  • the closure part is circumferential Slats or the like arranged, which are inclined at a predetermined angle relative to the peripheral surface of the closure part, in each case in the same direction, and which are assigned radially arranged and axially extending groove-like recesses in the closure part.
  • the slats slide over the grooves and offer no hold between the closure part and the receiving part and the user knows in this case that he must press the container towards the receiving part before the container can be released from the evaporation device.
  • a part of an evaporation device is shown, namely a lower housing part, which serves to hold a container, not shown, containing the volatile active substances.
  • the housing is designated 1 in Fig. 1 and has on its underside a downward receiving part (cap with screw thread) 2, which contains an internal thread 3, into which an externally threaded bottle neck of a bottle or other container can be screwed.
  • a wick or another element that transfers the active substances in the container upwards a preferably circular recess 4 is provided in the housing part 1, above which means are arranged in order to distribute the active substances transported via the wick-shaped element.
  • the design M 91 07 753.2 is made to the design M 91 07 753.2.
  • the receiving part 2 is of a conventional type, i.e. a screwable bottle into the receiving part 2 is screwed in or released depending on the direction of rotation over the housing 1. Means which prevent unintentional loosening of the container or bottle relative to the receiving part 2 are not provided here.
  • FIG. 2 shows a view of a receiving part 12 which replaces the receiving part 2 shown in FIG. 1 and which, in contrast to the receiving part 2 according to FIG. 1, has no internal thread.
  • the for the implementation of a wick provided circular recess is designated 14 in Fig. 2.
  • a bottom of the receiving part 12, which is numbered 16 has projections 18a, 18b, etc. arranged around the circumference, which are arranged along the circular wall 20 and an oblique flank 21a, 21b, etc., and a flank 22a, which runs essentially perpendicular to the bottom 16 , 22b.
  • the central opening 14 is surrounded by a flange-like extension of all cylinders 24, which points from the bottom 16 in the direction of an opening of the receiving part 12, which opening is designated by 26.
  • Fig. 3 shows a sectional view of the receiving part 12 without showing the other profiles and receiving sections belonging to the relevant housing parts. In this respect, reference is made to FIG. 1.
  • closure part wall 20 At the lower end of the closure part wall 20 there is a circumferential and inwardly facing rib 28 on the inner surface thereof.
  • a closure part 30 is inserted into the receiving part 12, which is shown in partial view and in partial sectional view in FIG. 4 and in plan view in FIG. 5.
  • the closure part 30 has a height which corresponds to the height of the wall 20 from the bottom to the circumferential rib 28. Furthermore, the closure part 30 is provided with a central opening 32 which corresponds to the diameter of the opening 14 of the receiving part 12.
  • the closure part or threaded part 30 has a substantially cylindrical shape and has an annular edge or bottom 34, from which teeth 35a, 35b etc. protrude in the direction of the central opening 32 of the closure part 30.
  • the teeth 35a, 35b are spaced apart and have an approximately conical shape, i.e. they are blunted, but essentially tapering.
  • the teeth 35a, 35b are from the annular edge 34, which is perpendicular to the wall 36 of the closure part 30, in the direction of that facing away from the edge 34 Opening 38, ie bent downwards in FIG. 4.
  • ribs 40a, 40b etc. which run parallel to the axis and can be displaced into engagement with the projections 18a, 18b etc.
  • the closure part 30 has an outer diameter including diametrically opposite ribs 40a, which corresponds to the inner diameter of the receiving part 12, while the radial depth of the projections 18a approximately corresponds to the height of the ribs 40a, 40b etc. relative to the cylindrical or circular wall of the Closure part 30 corresponds. In this way, an engagement between the ribs 40a, 40b etc. on the one hand and the projections 18a, 18b etc. on the other hand is possible.
  • the closure part 30 is inserted into the receiving part 12 so that its opening 32 comes to lie flush with the opening 14.
  • the teeth 35a, 35b rest with their ends facing the opening 32 on the free ring edge of the flange 24.
  • An edge 42 of the closure part 30 which delimits the internal thread comes into contact with the rib 28 as soon as the closure part 30 is inserted into the receiving part 12. A displacement of the closure part 30 out of the receiving part 12 is prevented by the interaction of the edge 42 with the rib 28.
  • the closure part is reduced in diameter from a predetermined height starting from the edge 34 in order to ensure easy assembly by plugging the closure part and the receiving part together.
  • the locking ribs 40a, 40b etc. When the bottle is additionally pushed in towards the bottom of the receiving part 12, the locking ribs 40a, 40b etc. additionally come into engagement with the flank 22a, 22b etc. of the projections 18a, 18b and provide an additional hold.
  • the teeth 35a, 35b basically hold the receiving part 12 and the closure part 30 in connection with the ring flange 24 at a mutual distance, ie without exerting pressure on the bottle, not shown, in the direction of the receiving part 12.
  • the ribs 40a, 40b etc. become one hand On the other hand, kept at a distance from the projections 18a, 18b etc., an inadvertent loosening of the bottle screwed into the closure part 30 is prevented and a rotation of the bottle counterclockwise in FIG. 5 causes the closure part 30 to also rotate.
  • the receiving part 1 according to FIG. 1 is replaced by a cap-like part 12 according to FIGS. 2 and 3 or FIGS. 6 and 7, which has no internal thread, but contains a closure part 30 carrying an internal thread.
  • the screw connection between the bottle neck and the closure part 30 is to be carried out.
  • the cap-like part 12 serves only to hold the closure part 30 and, when pressure is exerted from the receiving part 12 on the closure part 30, or vice versa, to ensure the engagement between the ribs 40a, 40b etc. on the one hand and the projections 18a, 18b etc. on the other hand to enable.
  • FIG. 6 shows a top view of a receiving part 12
  • FIG. 7 shows a partial sectional view of the receiving part according to FIG. 6.
  • FIGS. 8 and 9 show a correspondingly modified modification of the closure part 30 in partial view and partial sectional view, as well as partial top view 9 are the same reference numerals for the same parts as used in connection with FIGS. 2 to 5.
  • the receiving part 12 is circumferentially provided with at least one groove 50 which extends in the axial direction and which, according to FIG. 6, can be provided as an angular bulge or preferably as a rectangular groove.
  • four such grooves or bulges are provided on the inner wall surface of the wall 20, preferably diametrically opposite one another in pairs.
  • FIG. 7 shows the groove or bulge 50 in the region of the wall 20. These bulges or grooves 50, which run in the axial direction, serve to interact with corresponding latching elements, preferably in the form of lamellae 52, 54, which are arranged on the closure part 30.
  • the locking elements or lamellae 52, 54, etc. are formed on the outer wall 36 and inclined relative to the wall 36 in the manner shown in FIG. 9, ie the lamellae 52, 54, etc do not run radially with respect to the center point of the closure part 30, but are at an angle of, for example, 45 ° with respect to the tangent which runs on the outer wall 36 at its shaping point.
  • the slats 52, 54 are directed in a counterclockwise direction to the closure part 30, whereby a rotation of the closure part 30 in the clockwise direction relative to the receiving part 12 is possible, while in the case of a counterclockwise rotation the slats 52, 54 etc. into the recesses 50 engage and the further rotation in the counterclockwise direction with respect to the receiving part 12 is blocked.
  • the lamellae or latching tongues 52, 54 etc. preferably have a width which corresponds to approximately half the height of the closure part 30 and are designed to extend close to the edge 38 or from the edge 38 (FIG. 8).
  • the height of the ring flange 24 is matched in relation to the course of the teeth 35a, 35b, etc.
  • these teeth extend from the ring edge 34 in FIG. 4 so far down that their ends are at a distance from the ring edge or the plane defined by the ring edge 36 adhere to, which is about as large as the height of the ring flange 24.
  • FIG. 10 shows a sectional view of an embodiment of a bottle 60 used in conjunction with the evaporation device.
  • a closure part 63 is inserted, which is conical in sectional view and is provided at its lower end with a central opening 64, which is used to carry out a wick.
  • the closure part 30, shown schematically in FIG. 10 above the bottle neck 62, is configured with regard to its teeth 35a, 35b etc. in such a way that, when the bottle neck 62 is screwed into the closure part 30, there is a sufficient distance between the teeth 35a, 35b etc. on the one hand and that at the top facing surface of the conical closure element 63 is ensured on the other hand, ie the spring action between the ring flange 24 and the teeth 35a, 35b etc. is not impaired by the closure element 63.
