Definitions

• the invention relates to a cap for a discharge head of a medium container with a sealed into a container neck metering pump for aspiration from the medium container and donations of medium at a triggerable by operating the discharge head pump stroke according to the preamble of claim 1.
• Such liquid containers with metering pumps especially if their contents represent a certain potential hazard, such as. Medical devices must be lockable for children.
• dosing pumps are used in many different designs with spray head, troubleshooting adapter, throat adapter, etc., to enable the metered removal of liquid medication from containers or bottles.
• the object of the invention is therefore to provide a child-resistant closure, which prevents the removal of medium for children, especially a certain age group, while easy to manufacture, assembly and Operation is.
• a closure in the form of a cap is created, which provides a child-resistant closure and the removal of adults only slightly difficult.
• the closure protects the sensitive actuating head against damage as a protective cap.
• the attachment is possible at any time, even later. There is no need for any special modification or adaptation of the existing metering pumps.
• the cap is an attachment.
• FIG. 1 shows a side view of an upper portion of a medium container with metering pump
• FIG. 3 shows the medium container according to FIG. 1 with attached discharge head according to FIG. 2, FIG.
• FIG. 4 shows a side view of a closure cap according to a first exemplary embodiment in assembly sequence
• FIG. 5 shows a side view of the assembled cap according to FIG. 4, FIG.
• FIGS. 6 to 8 show various sections of FIG. 5,
• FIG. 9 and 10 show views of the closure cap according to FIG. 4 with the lower part mounted and the upper part removed
• FIG. 11 shows a side view of an assembled closure cap according to a second embodiment

• FIG. 14 shows a view of the closure cap according to a third embodiment with mounted lower part and removed upper part
• FIG. 15 shows a view of the closure cap according to a fourth embodiment with mounted lower part and removed upper part
• Fig. 16 shows a view of the cap according to a fifth embodiment with mounted base and removed top.
• Fig. 1 to Fig. 3 show a container 22 for medium, in particular liquid, with a metering pump 21, on the cylinder 3, a discharge head 20 can be placed.
• the discharge head 20 is at the same time actuating head and is here designed with a troubleshooting adapter 24.
• the metering pump 21 shown has a crimp ring 1 made of metal, which is crimped around a retaining edge 46 of the container neck 6.
• the discharge head 20 is usually placed after crimping the metering pump 21 on the cylinder 3.
• the metering pump 21 may alternatively close the container 22 via other types of fastening such as screw or snap closures.
• the metering pump 21 is thus sealed in the container neck 6 used for suction from the medium container 22 and donations of medium at a triggerable by operating the discharge head 20 pump stroke.
• Fig. 3 shows the attached discharge head 20, which is usually held only by a press fit between the cylinder 3 and a receiving bore 2 on the discharge head 20 on the metering pump 21. So it is always possible to withdraw the discharge head 20 with relatively little effort again.
• Fig. 4 shows the cap according to the invention in the order in which it is mounted as a closure.
• the closure cap then comprises a sleeve-like lower part 4, which can be fastened to the container neck 6 and releasably latched to an upper part 5.
• the lower part 4 is insoluble with the container neck 6 and thus with the container 22 and inserted and for example flared metering pump 21 connected.
• the lower part 4 is preferably a on the container neck 6, here the crimp ring 1, schnaufbares component in the form of a broad-ring-like shell, which sits on the crimp ring 1.
• the lower part 4 may also be attached to the container neck 6 in the manner of a clip.
• the lower part 4 for attachment to the container neck 6 at a lower edge slanted jaws 7, which can escape when pushing the lower part 4 on the crimp ring 1 upwards and reaching an end position in their original Able to return. A removal of the lower part 4 is then no longer possible.
• the final position of the lower part 4 can be determined by stops 8. The hemming ring 1 is then clamped between the jaws 7 and the stops 8.
• Fig. 4 shows that the lower part 4 has to lock with the upper part 5 locking edges 9 on the outside.
• a number of locking edges 9 are circumferentially distributed and spaced from one another along an upper edge region of the lower part 4.
• the locking edges 9 are ribs protruding from the outer side, each having a stop 17 at one end. Between the locking edges 9 each gaps 25 are left.
• the lower part 4 also has on an inner side locking lugs 10, which protrude from the inside.
• the locking lugs 10 are distributed circumferentially on the inside, leaving a radial distance to the outer periphery of the metering pump 21.
• the position of the locking edges 9 and the locking lugs 10 is aligned with each other to achieve a locking with locking elements on the upper part 5, as will be described below.
• the lower part 4 preferably has a sliding surface 15 which can be formed by an upper edge of the sleeve-like lower part 4.
• the upper part 5 is designed like a cap and has a widening lower edge region 40, which overlaps the upper edge region of the lower part 4, where the locking edges 9 are arranged.
• the upper part 5 has on a lower edge of the lower edge region 40 inside projecting locking edges 11, which can be brought into engagement with the locking edges 9 of the lower part 4, whereby a removal of the upper part 5 is prevented ,
• the upper part 5 engages with its locking edges 11 under the locking edges 9 of the lower part 4.
• the sliding surface 15 on the lower part 4 is also preferably associated with a Jacobgleit Structure 16 on the upper part 5, as shown in FIG. For locking the upper part 5 is placed so that the locking edges 11 of the upper part 5 through the intermediate spaces 25 of the locking edges 9 of the lower part
• the upper part 5 to slide under the locking edges 9 of the lower part 4 to the stop 17.
• the upper part 5 preferably above above arranged recesses 41 through which the locking edges 9 of the lower part 4 are visible when locking.
• the locking edges 11 of the upper part 5 are preferably ribs with a length which is adapted to the length of the intermediate spaces 25, so that a pushing through the same is possible in a simple manner.
• the upper part 5 has an integrally formed resilient locking arm 12 with an actuating surface 14.
• the locking arm 12 has a locking tooth 42 with a locking edge 13 which, in cooperation with the locking lugs 10 of the lower part 4, prevents a rotational movement required for unlocking.
• the locking tooth 42 is located on a circumferential line on the inside spaced from the circumferential line on which the locking edges 11 are arranged.
• the locking tooth 42 can engage the upper part 5 by engaging with the locking lugs 10 on the inside of the lower part 4. For this purpose, the locking tooth 42 is moved behind a locking lug 10.
• the resilient locking arm 12 of the upper part 5 is preferably pressed against bevels 18 of the locking lugs 10 of the lower part 4 against the spring force inwards.
• the locking edge 13 of the locking arm 12 jumps behind a retaining edge 19 of the locking lug 10.
• the upper part is now in the locked state.
• the actuation or removal of the discharge head 20 is no longer possible.
• the locking edge In order to unlock the upper part again, the locking edge must be brought by means of the actuating surface of the locking arm 12 in the release position and the upper part 5 are simultaneously rotated counterclockwise.
• the lower part 4 which is permanently connected to the container 22 and crimp ring 1, can still rotate freely about its axis. This provides an additional level of difficulty because when unlocking the upper part 5, the lower part 4 must be held with the other hand.
• FIGS. 11 to 13 show a second exemplary embodiment of the closure cap with an integrally formed tab 26, which serves as quality assurance.
