Definitions

  • the invention relates to a closure cap for openings in containers, which are used in particular for the storage of cleaning agents, cosmetics or the like, consisting of a cap housing which can be placed on the container opening in a media-tight manner and has at least one metering opening and one which can be pivoted on the cap housing attachable head plate with which the container opening can optionally be tightly closed and opened.
  • Such a closure device is known from German patent application P 195 41 830.
  • the metering opening is released by pressure on one side of the head plate, so that the medium contained in the container can escape.
  • the head plate can be locked in different positions by cams, whereby the metering opening is more or less released, so that the media flow increases or decreases accordingly.
  • unintentional opening of the cap cannot be prevented. This is particularly problematic when the containers are transported and the cap z. B. is inadvertently opened by hitting or abutting objects against the head plate.
  • the invention is based on the object of further developing a generic closure cap in such a way that unintentional opening is not possible and no additional packaging is required for the transport.
  • this object is achieved in that a locking device is provided on the closure cap, with which the head plate can be firmly locked in its closed position.
  • the locking device prevents accidental opening NEN the cap.
  • the locking device visualizes that the closure cap is closed.
  • the closure cap is preferably designed in such a way that the locking device engages in at least one recess which is formed on the head plate or can be placed below the head plate. In this way, a form-fitting, firm locking is achieved.
  • At least two slot-like material recesses which run essentially parallel to the longitudinal axis of the cap housing are formed in the outer surface of the cap housing, so that a locking lever is formed between these material recesses is connected to the cap housing via material bridges.
  • the design of the locking device as a locking lever significantly simplifies the manufacture of the closure cap, since the locking lever does not have to be fastened as an additional component by means of, for example, cams which are located in suitably designed recesses, but rather is attached directly to the cap housing can be shaped.
  • the cap housing can also be provided with incisions subsequently, which run according to the material recesses described above and thus form a locking lever.
  • conventional sealing caps without a locking lever in which no recesses are provided in the injection mold, can also be provided with such a locking lever.
  • the material bridges formed between the locking lever and the cap housing are constructed such that they have a suitable pretension and stability in order to ensure the closure of the closure cap.
  • the cap housing in the area of the locking lever has an outer surface Recess, the lowest point of which is located approximately in the area of the lower edge of the head plate in the closed state.
  • the locking lever can thus easily reach under the lower peripheral edge of the head plate without an additional locking device, such as a groove or the like, having to be provided for the engagement of the locking lever. If the upper front end of the locking lever protrudes somewhat beyond the lower peripheral edge of the head plate, when the locking lever snaps under the head plate it is ensured that the connection is held under tension and the locking lever cannot jump out of its own accord.
  • the outer surface of the cap housing has four material recesses running essentially parallel to the longitudinal axis of the cap housing, two of which run towards one another from the upper end face of the cap housing and two from the lower end face of the cap housing, and that Material bridges are formed between the converging material recesses.
  • the locking lever thus has the shape of a tab formed on the cap housing.
  • Other expedient configurations of the locking lever are possible, for example it can be conical.
  • the closure cap according to the invention is preferably injection molded from plastic. In order to emphasize the locking lever and its position more clearly, it can be designed in a color different from the color of the rest of the cap housing. In the same way, depressions, raster or signal words such as "press" can be formed on the locking lever in order to make its mode of operation clear to the user.
  • the material Takes preferably arranged so that the material bridges are formed at the height of the transverse wall.
  • This internal fastening of the locking lever on the transverse wall increases the durability since, in addition to the material bridges, a further fastening surface is formed.
  • the fastening of the transverse wall to the locking lever can be designed so that it exerts an additional restoring force or tensioning force on the locking lever.
  • At least one latching cam is formed on at least one of the material recesses on the side wall of the cap housing and / or the locking lever.
  • the locking cam acts as a reset lock for the locking lever.
  • a suitable structural design of the locking cam ensures that the locking lever can only be moved from or into its desired position by applying a required minimum restoring force. An accidental release of the locking lever is made impossible. The contact force between the locking cams is then greater than the restoring force exerted on the locking lever.
  • locking cams are formed on the opposite side walls of each material recess, which are in engagement with each other. It is particularly advantageous if the locking ridges face each other.
  • a further manufacturing simplification of the closure cap according to the invention is achieved if the locking cams are integrally formed on the cap housing and / or the locking lever.
  • a locking pocket is formed on the inside of the upper front end of the locking lever, against which at least the outer peripheral side of the closure cap can be placed.
  • this latching pocket ensures that the locking lever of the closure cap is properly seated in the closed position. Besides that, too prevents the locking lever from slipping under the cap due to excessive forces and possibly breaking off due to excessive torsional forces. As a result of this slipping through, the closure cap would also no longer be held in its desired position or closure position.
  • a locking tab can of course also be formed, which engages around the closure cap in the closed state. This tab can then also be designed so that it breaks off when the locking lever is moved from its closed position into the open position. In this way, the locking lever also acts as a tamper-evident closure.
  • the injection molds of the closure cap can be designed so that the locking lever extends transversely to the outer surface of the cap housing. In this way, the biasing force of the locking lever is increased. In addition, it can be ensured in this way that the locking lever always assumes the locking position by itself, without the user having to pretension it. The user must then consciously remove the locking lever each time in order to expose the metering opening of the closure cap.
  • the upper end of the locking lever preferably has at least one cam on the inside, which can be placed below the rocker arm or engages in a recess formed on the rocker arm.
  • the positive connection is achieved even without a recess.
  • a cam is formed on the rocker arm, which engages in a groove formed in a corresponding manner on the rocker arm.
  • the head plate is designed as a head cover.
  • the head cover lies against the entire peripheral edge of the upper end face of the cap housing.
  • the headstock can but also extend only over a certain area of the upper part of the closure cap, so that it forms a strip which is movable within the closure cap surrounding it.
  • closure cap according to the invention is illustrated by way of example in the drawing and described in detail below with reference to the drawings.
  • 1 is a sectional side view of the closure cap according to the invention with the locking lever locked;
  • FIG. 2 shows the view from FIG. 1 with the locking lever released and the head plate open.
  • FIG. 3 shows a side view of the closure cap according to the invention in the direction of arrow III according to FIG. 1,
  • FIG. 4 shows an enlarged illustration of the locking lever in the viewing direction along arrow IV according to FIGS. 1 and
  • FIG. 5 shows an enlarged illustration of the locking lever in the viewing direction along arrow V according to FIG. 2.
  • the closure cap 1 consists of a cap housing 2, to which a head plate 4 is pivotably attached by means of cams which engage in pockets and are not shown in the figures.
  • the closure cap 1 is fastened to the container opening 3 by means of a socket 5 provided with an internal thread.
  • This attachment can be designed to be detachable and non-detachable.
  • the socket 5 can also be fastened to the container opening 3 by means of other suitable methods, for example a snap closure.
  • the socket 5 is on the cap housing 2 with a substantially transverse to the longitudinal Axis of the sealing cap extending transverse wall 6 on the inside of the outer surface of the cap housing 2 is attached.
  • the closure cap is moved from the closure position shown in FIG. 1 to the open position while the head plate 4 is actuated, as illustrated by way of example in FIG. 2, the lower end of the tubular closure element 7 is spaced from the sealing seat 8 and the outlet duct 9 with its end facing the inner wall of the cap housing 2 is pivoted upward and the outlet opening 10 arranged at the end of the outlet duct 9 is arranged above the cap housing edge.
  • the locking lever 11 which engages under the lower edge of the head plate 4, must be brought out of the closed position. This is done by exerting pressure on the lower end of the locking lever 11a by the user. The force thus exerted releases the locking lever 6 from its closed position with the lever arm of the locking lever 6.
  • the fulcrum of the lever arm lies at the material bridges 12, on which a torsional moment is exerted by the lever arm.
  • the material properties of the plastic of the material bridges 12 generate the corresponding restoring force of the locking lever 6.
  • the locking lever 6 can be molded from the outset so that it extends transversely to the outer surface of the cap housing 2, so that the upper end 11b of itself is always arranged in the locking position and can only be guided out of this locking position by deliberate release by pressing on the lower end of the locking lever 11a.
  • the design of the locking lever 6 can be seen in particular from FIG. 3.
  • the outer surface of the cap housing 2 has four material recesses 13, 14 which run essentially parallel to the longitudinal axis of the cap housing 2, two of which run towards one another from the upper end face of the cap housing 15 and two from the lower end face of the cap housing 16, so that the material bridges 12 are formed between them.
  • the material recesses 13 and 14 run parallel to the longitudinal axis of the cap housing 2. Of course, these can also run obliquely to the longitudinal axis of the cap housing 2.
  • the cap housing 2 has in the area of the locking lever 11 on its outer surface a recess 17, the lowest point 17 a of which is located approximately in the area of the lower edge of the head plate 4. In the closed position, the head plate 11 rests on the upper end of the locking lever Ilb and clamps it in, so that the unit is always kept under tension and an independent release of the closing flap is not possible.
  • closure flap can also be designed such that the lowest point of the recess 17a is arranged above the upper end of the locking lever 11b.
  • the locking lever 11 extends transversely to the outer surface of the cap housing 2, so that it is in the transverse position by itself and does not have to be held in this position by the head plate 4.
  • the upper end of the locking lever has a latch pocket 18 on the inside thereof, against which at least the outer circumferential side of the head plate 4 can be placed.
  • the outer circumferential edge of the head plate 4 lies in this locking pocket 18 in the locking position, which ensures that the locking lever 11 is more firmly seated due to the positive locking. At the same time it is prevented that the locking lever is pushed under the head plate 4 during the locking process and thus possibly breaks off.
  • the locking lever 11 can also have an additional tab, not shown, on its inside, which deliberately engages around the lower edge of the head plate 4.
  • the plastic of the closure cap or this tab can then be made up of two Be trained types. On the one hand, it can be such that it releases the head plate when the locking lever is released by applying a certain predefined force, and on the other hand it can be designed such that it breaks off during this release process.
  • the second solution thus also ensures tamper-evident for the closure cap according to the invention
  • detent cams 19 are integrally formed on the side walls of the cap housing and the locking lever 19. These locking cams 19 are arranged so that they face each other and are so large that they cannot slide past one another without external force.
  • the locking lever 11 is shown in its closed position. In order to bring the locking lever 11 into the open position, which is shown in Figure 5, by pressing the locking lever
  • the minimum force to be applied is overcome so that the locking cams 19 are pushed back due to the elasticity of the plastic material and the locking cams can slide past one another in the position shown in FIG.
  • the locking flap can thus only be unlocked by means of the force to be applied at least, whereby an unintentional unlocking is practically impossible.
  • the locking cams 19 also hold the locking lever 11 in its unlocked position, so that the user does not have to actuate the locking lever 11 each time to open the closure cap and to be able to remove the medium from the container.
  • the locking cams are arranged only at the upper end of the locking lever Ilb. Of course, they can also be arranged at other suitable locations along the material recesses 13 or 14, or a plurality of latching cams can be formed, as a result of which the minimum force to be applied accordingly for unlocking the locking lever is correspondingly greater.
  • the material bridges 12 need not be located in the location shown in FIG. 3. These can also be found at the bottom End of the locking lever Ilb or further at the upper end of the locking lever Ila, whereby the minimum force to be applied also changes. They can also be made substantially wider than in FIG. 3, as a result of which the restoring force or the force to be applied for unlocking is changed in accordance with the operating conditions.
  • the locking lever 11 need not necessarily be as long as shown in FIG. 3. It can also be considerably shorter than the rest of the closure cap 2 or protrude beyond the lower end face of the cap housing 16, so that it engages, for example, in a suitable trough formed on the container.
  • the closure cap according to the invention makes it possible to prevent unintentional opening, for example during transport. Due to the material design of the closure cap or the arrangement of locking cams, the force to be released can be designed as desired in accordance with the conditions of use.
  • the manufacture of the closure cap according to the invention is particularly simple, since no further parts for the locking lever have to be attached in separate work steps, but the entire closure cap can be injection-molded in one piece.
  • the lever can be fixed in its locking and opening position by appropriate design of the material bridges and locking cams.
  • the locking lever can be molded onto the cap housing in such a way that it automatically assumes the closed position.
