CHILD-SAFE TURNING CLOSURE

The invention relates to a child-resistant rotary closure according to the preamble of claim 1.

The document EP 1092643 B1 discloses a childproof pressure-twist closure for bottles. This screw cap has the disadvantage that it is relatively easy to open.

It is an object of the present invention to provide a child-proof rotary closure for containers, which is difficult for children and easy to open for adults and thus has a higher security.

This object is achieved with a child-resistant rotary closure having the features of claim 1. The dependent claims 2 to 17 relate to further, advantageously designed screw caps.

The object is achieved in particular with a child-resistant rotary closure for a container, comprising a locking part and a closure cap, wherein the closure cap is rotatably mounted on the locking part about a common axis of rotation, and wherein the locking part has an end face with at least one outlet opening, and wherein the locking part a the end face opposite end portion comprising a circumferentially extending, radially to the axis of rotation D resilient, externally accessible locking member, and wherein a radially projecting latching lug is connected to the locking element, and wherein the closure cap on the inside a over a portion in the circumferential direction extending recess with a stop edge _ _

and wherein the recess is arranged with respect to the latching nose such that, when the closure cap is completely rotated in the closing direction and is thus in a closed position, the latching nose resiliently abuts in the recess and a mutual rotation of

Closure cap and locking member thereby prevents the latching lug abuts against the stop edge, and that the latching lug and the stop edge are configured so adapted to each other that the latching lug by pressing the locking element in the direction of the axis of rotation out of the

Is raised recess so that the closure cap with respect to the locking member in an opening direction is rotatable, and thereby the cap releases the outlet opening.

The inventive container closure has the advantage that it can be opened only by pressing on the locking element and a simultaneous rotation of the closure cap, wherein the locking element is also arranged relatively inconspicuous.

In a preferred embodiment, the locking element is designed rather small and with respect to its shape preferably also the geometric shape of the container closure modeled so that the locking element rather inconspicuous but still easily accessible is arranged on the surface of the container closure.

In a further advantageous embodiment, the container closure comprises at least two locking elements arranged spaced apart in the circumferential direction. Preferably, both locking elements are operated simultaneously to open the container closure. However, it is also possible to provide only one of the locking elements with a locking effect, whereas the other or the rest Locking elements serve as dummies, without their being able to open the container closure.

The container closure can be designed with a closure cap which can be removed and screwed on again. Of the

However, container closure can also be designed such that upon rotation of the closure cap an outlet opening is released, which can be closed again by turning back the closure cap, without the cap is completely removed.

In a particularly advantageous embodiment, the locking part is rotatably mounted with respect to the container. As long as the cap is locked with the locking part can thus be constantly rotated on the cap without them being opened, this arrangement has the particular advantage that the closure can not be opened even with an extraordinarily large acting force, for example, in contrast to the disclosed in said document EP 1092643 Bl closure, which can be opened with a sufficiently large force application. In a further advantageous embodiment, the closure has a locking device which limits the maximum possible rotation of the closure and bottle. In an advantageous embodiment, this locking device is designed such that it acts only when closing the rotary closure, whereas this achieved when opening the rotary closure or when turning the mutually locked closure cap and locking part no effect. Such a closure is particularly difficult for children to open, whereas this is very easily possible for adults. The container closure according to the invention can in particular also be easily opened by elderly and / or motor-impaired people. _ _

The inventive container closure is particularly suitable for containers containing bulk materials or liquids.

The container closure can be connected to a wide variety of containers, in particular bottles or flat packages, in particular cardboard packaging.

The invention will be explained in more detail below with reference to embodiments, wherein the same reference numerals relate to the same objects. The figures show:

FIG. 1 shows a child-resistant rotary closure 1 for a container 5. The rotary closure 1 comprises a neck part 2, a locking part 3 and a closure cap 4, the neck part 2 not being visible in the illustrated view. The neck part 2 forms part of the container 5. The rotary closure 1 has an axis of rotation D, wherein the closure cap 4 can be unscrewed and removed from the locking part 3 by turning in the direction D 1, and be placed on the locking part 3 again by turning in direction D 2 can. However, the closure cap 4 can, as explained in detail below, only be rotated by pressing on the locking element 3e relative to the locking part 3 and thereby released from the locking part 3. In one possible embodiment of the rotary closure 1, the locking part 3 is rotatable relative to the container 5. When you open the

Rotary closure 1 is therefore preferably held with one hand both the apron 3d of the locking part 3 and the locking element 3e pressed inward to turn the cap 4 in the opening direction D 1 with the other hand.

The height of the locking element 3e may be, for example, between 2 mm and 2 cm, as required, and the length in the circumferential direction may also be between 2 mm and 2 cm. In addition to the surface of the locking elements 3c, the spring force required for opening or the required spring travel can also be configured in such a way that it is difficult for children to open. - -

To open the cap 4 is rotated in the direction of rotation D 1 about the rotation axis D until the cap 4 can be removed and completely removed.

FIG. 2 shows a neck part 2, which is firmly connected to a container 5 designed as a bottle. The neck part 2 comprises a cylindrical wall 2a, in the circumferential direction of which a projecting bead 2b extends. The neck part 2 also comprises a shoulder 2d, with a plurality of circumferentially spaced triangular webs 2c. It would also be possible to arrange only a single web 2c.

The neck part 2 could also, as shown in Figure 2a, have a circumferential flange 2e, which can be glued, for example, with a flat package to connect the neck part 2 fixed to the package.

The outlet 2a could also, as shown in Figure 2b, not only have a cylindrically shaped outlet, but also a different shape such as the illustrated kegeis truncated shape.

FIG. 3 shows a locking part 3, comprising an end face 3a and a skirt 3d surrounding the opposite end thereof, which has a locking element 3e with a latching nose 3f, wherein the locking element 3e is resiliently movable in the direction F or radially to the rotation axis D. The locking part 3 comprises a cylindrical attachment 3b and an external thread 3c extending along the attachment 3b.

As shown in FIG. 3 a, a circumferential flange 3 n could also be arranged on the skirt 3 d, which flange can be fixedly connected to a two-dimensional pack. In this embodiment, the cylindrical cap 3b extends under the apron 3d to the _ _

Flange 3n, and is sealed to this fluid. This ensures that the fluid flowing out from the container 5 via the attachment 3b can not flow out of the locking element 3e. The adjustment element 3e is movably mounted in the direction F as described in FIG. 3, in order thereby to release or lock the closure cap 4.

The locking part 3 could also have an attachment, which does not have a cylindrical configuration, but has a different design, such as shown in Figure 2b a frustoconical design.

Figure 4 shows a bottom view of the locking member 3 shown in Figure 3, wherein on this locking part 3, a cap 4 is placed. The locking part 3 comprises a plurality of circumferentially projecting ribs 3g, which serve to rotatably connect the locking part 3 to the bead 2b of the neck part with the neck part 2. The locking member 3 comprises in the illustrated embodiment, two protruding, resilient tabs 3i, which cooperate with the triangular webs 2c of the neck portion 2 such that the locking member 3 is rotatable in directions of rotation D 1, whereas the rotational path in the opposite direction of closure D2 is limited by the resilient tabs 3i get into abutment with the triangular web 2c, so that the locking part 3 can no longer be rotated in the direction of rotation D2.

The locking element 3e is resiliently connected to the rest of the locking part 3 via a narrow web. The closure cap 4 comprises a marking 4a, the inside of which has a depression 4e. In the closed state, the locking element 3e is located with latching lug 3f in the recess 4e, wherein the latching lug 3f also bears against the stop 4b in order to prevent a mutual rotation of the locking part 3 and the closure cap 4. Figure 5 shows a longitudinal section through a container 5, which is provided with the neck portion 2 shown in Figure 2 and on which neck portion 2, the locking member 3 shown in Figure 3 is placed. The locking part 3 is rotatably mounted on the bead 2b of the neck part 2 via the ribs 3g. In the illustrated embodiment, the resilient tab 3i is applied to the triangular web 2c, so that the locking member 3 can be rotated only in the direction of rotation D 1. One or more outlet openings 3h may be arranged on the front side 3a, depending on the requirement of the medium in the container 5. It may prove advantageous to arrange a circumferential sealing lip 3k projecting against the apron 3d on the front side 3a in order to seal the neck part 2 with respect to the locking part 3, so that the medium located in the container 5 is the container 5 only via the outlet openings 3h can leave. The rotary closure 1 is suitable in this embodiment for both solid means, such as powdery means, as well as liquid agents.

FIG. 6 shows a section along the section line AA according to FIG. 5. This shows, in particular, the interaction of the triangular webs 2c with the resilient tabs 3i. These two means 2c, 3i form a rotation limiting unit or a locking device and prevent rotation in the direction of rotation D2 as soon as the two means 2c, 3i reach the mutual stop. In contrast, a rotation in the direction of rotation D 1 is always possible because the tab 3i springs can move over the web 2c. This allows when screwing the cap 4 completely screw this with the locking part 3, so that in the fully closed state, the latching lug 3f comes to lie in the recess 4e and abuts the stop 4b. In contrast, the locking part 3 or the cap 4 placed thereon can be rotated continuously in the direction of rotation D 1 without the Remove cap 4, as long as the locking element 3e is not pressed. This causes a particularly high security against unintentional opening of the rotary closure 1. Instead of a web 2c could also be a recess, such as a groove formed, which acts together with the tab 3i as a locking device 2c, 3i.

Figure 7 shows a perspective view of the cap with marking 4a, on the inside of which a recess 4e and the stopper 4b is located. In addition, the closure cap 4 has an internal thread 4c. On the outside, the closure cap ribs 4d for easier holding and turning the cap 4. The closure cap 4 may have only a single marking 4a with a recess 4e and stop 4b or a plurality of circumferentially distributed

Markers 4a, for example two, three or even more. In addition, it is also possible, for example, for only one or two of the markings 4a to have a depression 4e with stop 4b, whereas the remaining markings 4a do not have a depression 4e with stop 4b, so that these latter marks 4a do not engage with the respective locking element 3e with snap-in nose 3f can interact.

FIG. 8 shows a longitudinal section of a child-resistant rotary closure 1 comprising a container 5, the upper part of which opens into a neck part 2. The locking member 3 is slipped over the neck portion 2 and thus, as described in Figures 1 to 7, rotatably connected to the neck portion 2. In addition, the cap 4 is screwed onto the locking part 3, so that the latching lug 3f engages in the recess 4e and rests against the stop 4b, so that the cap 4 is rotatably connected to the locking part 3. The closure cap 4 also covers the outlet openings 3h, so that the medium located in the container 5 can not escape via the outlet openings 3h. - -

Figure 9 shows a locking part 3, which is particularly suitable for a container 5, which contains a liquid. In contrast to the locking part shown in Figure 3, this locking part 3 has no external thread, but a circumferentially extending bead 31. In addition, a single outlet opening 3h is arranged on the end face 3a, which is also arranged at the end of a projecting nose 3m. Otherwise, the locking part shown in FIG. 9 is configured identically to the locking part shown in FIG.

FIG. 10 shows a longitudinal section through the locking part 3 shown in FIG. 9. The locking part 3 comprises an end face 3 a with protruding nose 3 m and outlet opening 3 h. In addition, the locking part 3 comprises a cylindrical attachment 3b with bead 31 and sealing lip 3k. In addition, the locking member 3 comprises circumferentially extending ribs 3g, a skirt 3d, a locking element 3e and a resilient tab 3i.

11 shows a longitudinal section through a closure cap 4, with a recess 4e, stop edge 4b, ribs 4g and a cover 4f for an outlet opening.

FIG. 12 shows a child-resistant rotary closure 1, the closure cap 4 of which is designed so that the closure cap 4 is not completely detachable, but after the locking element 3e has been actuated in the direction of rotation D 1 relative to the locking part 3 is rotatably supported mutually. In the direction of rotation D2 locking part 3 and cap 4 are mutually rotatable only until a lock takes place.

FIG. 12 shows the rotary closure 1 in the closed state in that the closure cap is arranged with respect to the nose 3m or the outlet opening 3h in such a way that the - -

Cap 4 covered by the cover 4f the outlet opening 3h and simultaneously closes. If, for now, the locking element 3e is pressed in towards the rotation axis D and the closure cap 4 is then rotated in the direction of rotation D 1, the circular segment-shaped recess 4h slides along the nose 3m, the cover 4f moving away from the outlet opening 3h and thus the outlet opening 3h and the Nose is released 3m. The medium located inside the container 5, in particular a liquid, can now be poured out via the outlet opening 3h.

In contrast to the embodiment shown in FIGS. 9 to 12, the locking part 3 may also have a plurality of outlet openings 3h which are covered by a common cover 4f or a plurality of individual covers 4f. In a further embodiment, the lugs 3m with outlet openings 3h can also be arranged at different locations on the front side 3a, that is to say distributed in the circumferential direction and / or in the radial direction, wherein the covers 4f and the recesses 4h are arranged to extend in such a way that open and close, in particular a simultaneous opening and closing of all outlet openings 3h is possible. A plurality of outlet openings 3h and covers 4f may also be arranged such that the outlet openings 3h function of the angle of rotation of the

Cap 4 are opened sequentially, so that, for example, first only a single outlet opening 3h is open, and in a further rotation of the cap 4 two outlet openings 3h are open, etc. The cap 4 may also have a latching device to the cap 4 in to hold the respective rotational position. Thus, the number of the opened outlet ports 3h can be adjusted. In contrast to the embodiments described in the present paragraph could in a further embodiment, the - -

Cap 4 are designed to be removable, for example, as shown in Figures 3 and 7, the cap 4 and the locking member 3 are provided with a thread 3c, 4d.

In the embodiment illustrated in FIGS. 9 to 12, the size of the outlet opening 3h is determined by the locking part 3. However, the size of the externally accessible outlet opening could also be determined by the mutual position of locking part 3 and rotatable cap 4, for example by the locking part 3 has a circular segment-shaped outlet opening 3h, with a segment angle of, for example, 45 degrees, and by this outlet opening 3h through the rotatable cap 4, depending on the angle of rotation, either not at all or partially covered completely, so that in addition to a fully open and closed outlet opening 3h the externally accessible portion of the outlet opening 3h, depending on the angle of rotation between cap 4 and locking part 3, have different sizes can.
