Description

Child-resistant discharge device

The invention relates to a child-resistant discharge device for media according to the preamble of claim 1.

The invention relates to a child-resistant discharge device which is intended to prevent children from coming into contact with the contents of a discharge device. Opening mechanisms are therefore provided that are not overcome by children. For some media, national and international laws even make mandatory the use of parental controls.

From DE 101 34 796 A1 discloses a discharge device for a medium according to the preamble of claim 1 is known, which prevents unauthorized access to the contents of the medium in a reservoir, especially for children. On the one hand is an unauthorized operation of a dosing head due to a manual detachable locking means excluded. On the other hand, unauthorized removal of the entire discharge of the reservoir is prevented, since a container closure part is blocked by a fuse.

From DE 698 03 036 T2 a discharge device for a medium is known, which comprises a closure device for an exit region of a storage container for the medium. The closure device has a sleeve-shaped closure part provided with an internal thread and can be screwed onto an external thread of the outlet region of the storage container designed as a neck. In order to prevent a renewed unscrewing of the closure device from the outlet region of the storage container and thus to achieve a security for the screwed-on discharge device and for the medium content of the storage container, the closure part is surrounded by a cap-like securing part. This is intended to prevent unauthorized access to the contents of the storage container by simply unscrewing the closure device.

The disadvantage is that the locking of a manually operable pump part by means of the known spring bars is not sufficiently reliable.

From US 4 496 082 A a discharge device is known in which the pump part can be blocked in an upper position and / or a lower position.

The object of the invention is therefore to provide a child-resistant discharge device for media, in which the unauthorized access to the contents of the reservoir is improved.

This object is solved by the features of claim 1.

As a result, a child-resistant discharge device is provided in which the function of spring bars is combined with a rotary movement to move the discharge in and out of a blocking position. Such a combined movement with a pressure and a rotational component causes a complex opening mechanism, which is considered to be child resistant.

The spring webs are inventively formed by wall portions of the discharge portion associated sleeve-shaped actuating handle. The functional points for exerting an external pressure force, which solves a joining position of the blocking position, are so integrable in the actuating handle, which improves the external optical impression of the dispensing device. Also, the functional unit of the discharge is not complicated by the child-resistant training by supplemented external components. It is sufficient to mark the areas of the sleeve-shaped actuating handle, which carry the respective inner, acting as a pawl tongue. For example, fingerpads, corrugations, etc. are suitable for marking. The compressive force to be used is adjustable by a choice of the wall thickness of the sleeve-shaped actuating handle, the provision of stiffeners, such as a cover, or a selection of materials.

In order for an external pressure force to be transmitted as evenly as possible to at least two wall sections on the inner tongues acting as pawls, aligned supports can be provided on a carrier part. Their orientation may be adaptable to a change in shape of the sleeve-shaped actuating handle by pressing the wall sections. In a round sleeve-shaped actuating handle can result in an elliptical deformation by pressing. If the supports are aligned in the direction of the elliptical deformation, the inner wall of the sleeve of the actuating handle can come into contact with the carrier part flatly.

Further embodiments of the invention are described in the following description and the dependent claims. The invention will be explained in more detail with reference to the embodiments illustrated in the accompanying drawings.

FIG. 18 schematically shows a section CC of FIG. 1. The invention relates to a child-resistant discharge device for media with a reservoir 1 and a sealed to the reservoir 1 via a closure element 2 mounted pump part 3 for conveying medium from the reservoir 1. On the pump part 3 is an operable discharge section 4, which at a the Closing element 2 associated carrier part 5 is guided axially displaceable for carrying out a lifting movement for the output of medium. The discharge section 4 is for actuation of the pump part 3 by an actuation path a between a lower actuation position shown in FIG. 10 and an upper rest position shown in FIG. 5 movable. In addition, the discharge section 4 is rotatable relative to the carrier part 5 about a central axis X. For carrying out the translational movement, preferably axially in the X direction, and for carrying out the rotational movement of the discharge section 4 with respect to the carrier part 5, the discharge section 4 is preferably fixed to the carrier part 5 via a snap connection 6 (compare FIGS. 11 to 14). The carrier part 5 itself is fixed to the closure element 2 by a fastening device 7, so that the carrier part 5 assumes a preferably fixed position relative to the container neck 8. The carrier part 5 and the closure element 2 can also be formed in one piece.

The closure element 2 can be provided in a known manner with an internal thread which can be screwed onto an external thread 9 on the container neck 8. A barbed toothing 10 can secure this screwing and prevent unscrewing. Alternatives to the screw cap are, for example, crimp seals or snap closures. The closure element 2 surrounds the container neck 8 preferably like a shell, whereby a withdrawal from the container neck 8 is difficult.

The shape of the discharge section 4 can be selected depending on the application. According to FIGS. 1 to 18, the discharge section 4 is, for example, in the form of a branch for a nasal application. For discharge of eye drops, the discharge section 4 is preferably shown with a shorter nozzle shape than illustrated educated.

To lock the discharge section 4 in the upper rest position, as shown in Fig. 1 to Fig. 5, the discharge section 4 by means of manually operable spring bars 11, 12 in at least one blocking position 13 on the support member 5 can be locked to unauthorized access to prevent the contents of the reservoir 1. The discharge section 4 is not movable in the blocking position 13 in the lower operating position. This is only possible if the spring bars 11, 12 are positioned in an actuating position 14 to the carrier part 5.

The spring webs 11, 12 are formed by wall sections 23 of the discharge section 4 associated sleeve-shaped actuating handle 15. The wall portions 23 each carry an inner, radially inwardly extending tongue 17, which are latched as pawls from a slide-like guide 25 in the support member 5 in the operating position 14 by rotating relative to the support member 5 in the blocking position 13. The support part 5 has supports 18 for end regions 28 of the wall sections 23, which support these as curved bending springs. Under external load, by compressing or pressing together the wall sections 23 in the direction Y (see FIG. This game allows opening of a joining position of the tongues 17 behind a notch 19 in the blocking position 13 and a turning back in the Z direction of the tongues 17 in the slot-like guide 25th

The wall sections 23 are preferably subregions of a sleeve wall of the actuating handle 15, in particular in one piece with the latter. The supports 18 are formed by edges of a cutout 29 in a sleeve-shaped wall 30 of the support part 5. Opposite the sleeve-shaped wall 30 of the support member 5 as an inner sleeve, the sleeve-shaped actuating handle 15 as an outer sleeve axially displaceable in the direction X for carrying out the lifting movement as Fig. 15 shows. The snap connection 6 allows twisting of carrier part 5 and discharge section 4 about the X-axis, which is here preferably the central axis.

The supports 18 formed by the edges are preferably sections of the sleeve-shaped wall 30 of the support part 5, which are aligned after an elliptical bending of the sleeve-shaped actuating handle 15 in the region of the wall sections 23 (see Fig. 3 and Fig. 15) by compressing the wall sections 23rd There is a difference between the diameter of the inner sleeve formed by the wall 30 and the outer sleeve formed by the sleeve-shaped actuating handle 15. This difference can be a measure of an adjustable by bending the wall sections 23 when squeezing the same game that allows release of the joining position between the tongues 17 and the latch 19 from the blocking position 13. By inserting a plate 31 on the head side of the sleeve-shaped actuating handle 15, a stiffening can be generated there. The bending of the wall sections 23 then concentrates on the free end 24 of the sleeve-shaped actuating handle. Deformation by bending due to compression of the wall portions 23 can thereby be made more direct and defined. The sleeve-shaped actuating handle 15 also has a suitable wall thickness and is made of a suitable material, whereby bends can occur during compression of the wall sections 23.

Preferably, two oppositely disposed spring bars 11, 12 are provided with wall portions 23. Instead of two opposite spring bars 11, 12 may also be provided a larger number of spring bars, which are arranged circumferentially distributed.

The cutouts 29 preferably have a vertical position at which the inner tongue 17 holds the discharge section 4 in the upper rest position by contact with a footprint 22. Blocked is thus preferably in the upper rest position against which the backdrop-like guide 25 is a movement of the inner tongues in the operating position 14 allowed in the lower operating position. The tongues 17 can be formed on the sleeve-shaped actuating handle 15 and optionally provided with a stiffening rib 20 to form the respective tongue 17 as a sufficiently rigid pawl.

The closure element 2 preferably has an axially extending, here the sleeve-shaped support member 5 penetrating dome 26 on. The dome 26 engages in an axial guide track 27 of the discharge section 4, whereby an axial support of the discharge section 4 on the closure element 2 during the lifting movement for media discharge and during rotation into the blocking position 13 is improved. A tilting of the discharge section 4, whereby a release of the blocking position 13 could be easier, is avoided.

An actuator 16 may be attached to the discharge section 4. As FIG. 15 shows, finally, a nozzle insert 32 and a fluid path insert 33 can be inserted into the discharge section 4 in known manner. Finally, to protect a nozzle 34 of the discharge section 4, a protective cap 35 can be mounted detachably. As shown in FIG. 13, the discharge portion 4 may have a port 36 for connecting the pump portion 3.

In the area of the wall sections 23, finger pads 40 can be arranged on the outside of the sleeve-shaped actuating handle 15, which make the arrangement of the tongues 17 externally recognizable and can also improve the feel when detecting the dispensing device.

Suitable materials are, in particular for the carrier part 5 and the actuating handle 15 thermoplastic materials, such as polypropylene (PP) or polyethylene (PE), optionally with additives. The reservoir 1 may in contrast also consist of glass. The mode of operation of the child safety device is as follows, as illustrated in FIG. 17 and FIG. 18 by means of the pressure and rotational movement arrows X, Y. By rotating the discharge section 4 and carrier part 5 in the direction Z according to FIG. 17, the respective inner tongues 17 can snap into the blocking position 13 via the respective catch 19 in the upper rest position. In the upper rest position of the discharge section 4 is held by a return spring of the pump part 3. From this locking locking position 13, the inner tongues 17 can only disengage by pressing against each other of the two spring bars 11, 12, ie the local wall sections 23. Under the effect of this pressure movement in the direction Y, the joining position between the respective inner tongue 17 and the associated catch 19 is released and a turning back of the inner tongues 17 in the operating position 14 done. The respective tongue 17 experiences namely an inwardly directed component of movement. This allows the respective inner tongue 17 to be moved back into the actuating position 14.

In the actuation position 14, the inner tongues 17 are arranged in the slide-like guide 25, where a lifting movement of the discharge section 4 is again possible.

Fig. 1 and Fig. 16 illustrate the movements for releasing the blocking position using the labels "turn" (turning), "press" (press) and "pump" (pumps for media output).
