DOUBLE CAP WITH CHILD LOCK

The invention relates to a double protective cap made of elastic plastic Child safety lock for spray cans, with an outer one sitting on the edge of the can Jacket and an inner jacket, the inwardly curved edge of which engages behind the valve dome, while the inner jacket consists of two segments that are mutually exclusive are diametrically opposed at a mutual distance.

In one of the utility model 77 12 650 known protective cap this You can use the blade of a screwdriver through a window in the outer cap shell into one formed between the segments of the inner cap shell Insert the gap and twist the blade, thereby enlarging the gap and pulling the inwardly curved edge of the segments from the valve dome radially outwards, so that the push-on cap comes free. Young children still don't grasp this kind of thing Handling a screwdriver, and therein is the child safety which prevents unauthorized actuation of the opening valve covered by the protective cap in the valve dome on the top of the spray paint can.

But a screwdriver or similar tool is the authorized user not always at hand, which makes a spray paint can equipped in this way is considerably reduced.

The object of the invention, on the other hand, is to provide a double protective cap of the initially mentioned mentioned genus so that it can be unlocked without tools, anyway but in such a way that small children cannot unlock it.

For this purpose, it is proposed according to the invention that the segments are bridged by them integrally formed roof-shaped pointing towards the outer jacket and preferably contiguous to it along their ridge lines Wedge pieces. If you press the cap on its outer jacket between your thumb and forefinger in the area of the wedge pieces, it deforms outer shell oval, and this movement is transmitted through the wedge pieces of the inner shell to its segments, which are spread apart, the inwardly bent edges of which come free from the edge of the valve dome, so that the cap can be pulled off. A small child is not in that Able to understand these relationships, and neither can the cap diameter Clamp commercially available spray cans between thumb and forefinger, at least not with the force required for deformation. This is what the child safety device according to the invention consists of.

In a further development of the invention, the outer jacket can be retractions or a have reduced wall thickness in the circumferential area of the inner shell parts. This results in a pronounced flat-oval deformation when it is compressed achieved and a correspondingly greater leverage exerted on the wedge pieces on the segments of the inner shell, and these are spread more widely.

Furthermore, the outer jacket can expediently in the circumferential area of the wedge pieces each have a corrugation on the outside. This prevents the user's fingers from sliding off the cap shell when they are pressed together.

The invention may be based on the exemplary embodiment shown schematically in the figures further explained. Show it

attached cap,
FIG. 5 shows the handling of the cap in a perspective view.

The double protective cap is injection-molded in one piece from elastic plastic and consists of an outer jacket 1 and an inner jacket, which is made up of two segments 2, which are diametrically opposed to each other at a mutual distance. They are bridged by pointing towards the outer jacket 1 in a roof shape and wedge pieces 4 connected to it along their ridge lines 3. In the area of the ridge lines 3, the outer surface of the outer casing 1 is corrugated molded, which are therefore diametrically opposite each other.

The double protective cap sits in a manner known per se on one of the figures 4 and 5 partially shown, also known spray can 6. This engages behind the inwardly curved edge 7 of the inner shell parts 2 the valve dome at its connection to the valve disk 9 forming bead 10, as best can be seen from FIG.

If you now press, as shown in Figure 5, between your thumb and forefinger the two corrugations 5 on the outer cap shell 1 against each other, so deformed it is oval, which is favored by the fact that the outer jacket 1 in the circumferential area of the inner shell parts 2, forms indentations 11 at its edge, as can best be seen from FIGS. 1 and 3.
