Childproof lock

The invention relates to a childproof lock of the type mentioned in the preamble of claim 1.

Closures for containers, especially bottles, are mass-produced items, which have to be produced at low cost. The object of the present invention is to to design such closures with hardly any appreciable increase in production costs so that they, accordingly the expected regulations, cannot be opened by children. This task is carried out with the one mentioned at the beginning Closure achieved by the features of claim 1.

Claim 1 speaks of diameters and an oval deformation. These expressions were used for linguistic simplification and also chosen because a main field of application of the invention is circular closures. It should but also closures are included, which are already from the house have an oval or a polygonal shape.

The fact that during the opening process of the closure An oval deformation is required, the contents of the container become inaccessible to children, once because forces to the oval deformation

In the case of closures with a joint, an advantageous further development be provided according to claim 9. Here then the force on the oval to be deformed closure part is not exercised more along one diameter than along two motorcycle radii which form an obtuse angle 2o ( lock in. This results in a resulting force component that is directed away from the joint and thus In addition to the oval shape, it makes opening easier.

In an advantageous embodiment according to claim 10, the f oval deformation can be facilitated by the one closure part, that the wall thickness is thicker at the ends of the motor diameter or force radii than at locations transversely thereto.

Two exemplary embodiments of the invention emerge from the following description with reference to the drawing.

FIG. 1 is a vertical longitudinal section through an embodiment of the closure.

Figure 2 is a plan view of the base of this closure.

Figure 3 is a plan view of the lid of this closure.

FIG. 4 is a side view of the lid of this closure seen from the right or left in FIG.

Figures 5 and 7 are side views of other embodiments of child resistant fasteners.

Figure 6 is a plan view of part of the opened

• Closure according to Figure "5, with one in the lid looks inside.

The lower part 3 of the closure is on the neck 1 of a bottle attached. This can be done in a number of ways., for example by gluing, welding, screwing, etc. A bounce connection is shown here. The lower part has a pouring spout 5 and on two each other opposite points of its circumference each have a hook 7 with an outwardly directed nose.

The lid 9 has a sealing ring 11 which fits into the outer end of the pouring spout 5 in a sealing manner. To each other eyelets 13 are provided on opposite points of the cover (Figures 3 and 4). ' The lid is used to form the eyelets two projections 15 in the manner of radial flange parts which, in the top view of Figure 3, have an opening 17. In addition, the deodorant has (Figure 4) in its side wall 19 above both projections 15 each have an opening The two openings 17 and 21 merge into one another. The cover of Figure 1 is placed on the lower part, wherein the two hooks 7 engage in the two eyelets 13.

For the cover, the straight line 23 denotes the detent diameter j, because at its ends are the locking parts, namely here the eyelets 13. The dashed line 24 denotes the force diameter, which here runs at right angles to the detent diameter. Are with the lid closed from the outside with Thumb and forefinger along the force diameter 24 inwardly directed forces exerted, so the lid takes a oval shape, as shown by dashed lines in FIG. The cover stretches along the locking diameter 23 * so that the two Eyes 13 wander outwards, release the hooks 7 and the Lid can be lifted off.

On the cover there are protruding grooved finger rests 26 or the like, which make it clear where the button is pressed got to.

The closure can also be opened in other ways, namely by deformations on the lower part. For example can the hooks 7 together with the immediately adjacent part of the lower part 3 opposite the lower part bottom 27 and its Seal 28 can be arranged with respect to the bottle neck 1 in such a way that they press against one another elastically in the radial direction permit. The force diameter and the detent diameter then fall together. Both are labeled 25.

FIGS. 5 and 6 show a closure according to the invention with a film hinge 30 by which the lid is held in an articulated manner. Identical or similar parts are provided here with the same or apostrophized reference symbols. The same applies to a closure according to FIG. 7, which however has a spring hinge 36, 37, that is to say a hinge which ^{holds the cover 9 1} in its open position or in its closed position under spring force. These closures have only one hook 7 and one eyelet I3. Otherwise, however, these closures can be opened in the same way as was described. The finger rests 26 'are not arranged here exactly at the ends of a diameter, but rather more towards the joint, as FIG. 6 shows particularly clearly. The center of the finger rest with a radius running through the eyelet forms a central angle o ( which is greater than 90 °. The area within which the finger rest is located can preferably be between angles o \ of 100 ° and 120 °.

In these embodiments, one can no longer speak of a force diameter. It therefore becomes the expression "Kraftradien" introduced. The resulting motorcycle radii are denoted by 24 'in FIG. The ones from the fingers Forces exerted act inwardly along the motorcycle radii 24 ' and generate a force component in the direction of arrow 34. The counterforce to this force component is applied by the hand resting on the lower part 3 'of the closure via the film hinge 30 exercised. In this embodiment, the deformation thus acts almost exclusively in the direction of arrow 34 and thereby allows particularly problem-free actuation. A

oval-shaped cover is shown in dashed lines in FIG.

The oval deformation of the cover 9 'can be facilitated by the fact that the side wall 19 of the cover is made weaker in the area of the ends of the detent diameter 23 than in the area of the outer ends of the motorcycle radii (FIG. 6). The same applies to the cover 9 according to FIG. 3, where the greatest thickness of the side wall 19 is then provided in the area of the outer ends of the force diameter 2H- .

Instead of the illustrated embodiments with one or two outwardly directed hooks, which are arranged on the lower part inwardly pointing hooks on the lower part and inwardly or outwardly pointing hooks on the lid can also be used. The illustrated embodiments with outwardly directed hooks on the lower part and associated eyelets on the cover However, because of the possibility ^ are simply designed injection molds to use, particularly advantageous. You also get a good aesthetic impression.

The lower part J5 or 3 'can also be made in one piece with the container 1 be trained.

The protection extends to other embodiments as well of the invention than that presented, provided they fall under the scope of the claims, in particular to embodiments with locking parts that are designed differently but fulfill their purpose within the scope of the invention without one part could be called an eyelet and the other a hook.
