USA patent application JMr. 401 582

The invention relates to spray heads, which are protected against unauthorized actuation and provided with a protective device, for Eros oil container.

They are spray heads for aerosol containers with one on the container to be fastened cap and one arranged within the same, having a nozzle and on the pin of the aerosol valve slip-on actuating head known, which is only attached to the cap by destroying or removing one Sehutzelementes is accessible to the consumer.

With known devices of this type (utility model 1 825 089) a protective cap that is open at the top and firmly connected to the aerosol container is provided. Inside this Protective cap is the operating button on the top of which is a depressible button, which is through a I-film attached to the open upper face of the cap is secured against unintentional or unauthorized depressing. This film is the first time the devices are operated torn. This known device makes the use of additional material, namely a plastic polie, in its manufacture necessary. It must also be introduced in the manufacture of the cap additional operations through which cut the sole in the desired shape and size or punched out and then placed in the desired position on the spray head and finally welded to this. In the case of a mass-produced article, such as a spray head for spray cans or the like, the additional manufacturing costs associated therewith fall substantial weight. The security film provided in these devices is also functional Disadvantages for the spray head. The film is not or at least not completely removed from the spray head when it is first activated removed. The remaining polien rests are in the upper opening. the cap and can press the push button located above the actuating button inside the cap jam so that the operating button is prevented from returning to the closed position of the valve.

In other known devices of this type (USA patent 3 133 680) is a safety plate underneath the operating button arranged, the central upwardly curved part by a tear strip from the outer annular The rope can be separated so that the actuating button can then be pressed in. Even with these known devices Remnants of the safety device remain on the spray can or on the actuation button and can lead to malfunctions To give reason.

In contrast, the invention is based on the object of creating a significantly improved guarantee, which prevents the mentioned disadvantages of the known devices of this type and also as an original safety element can be formed particularly cheaply and easily on the actuator cap. The element of the guarantee lock to be removed should be able to be completely removed with certainty and, moreover, no overpressure build-up before it is removed in the cap through any aerosol substance or abrasive escaping from the spray can.

According to the invention, this is achieved in that the protective element is formed by a wall part made of the same material as the rest of the rope of the cap, with the the rest of the cap part is made in one piece and connected to the same by several breakable webs.

In this way it is achieved that the protective element "at first actuation "or before the first actuation can be removed completely without effort and with certainty. The spray head according to the invention can be easily and cheaply molded from plastic with its protective element and also easily and cheaply assemble and attach to the spray can. It is characterized by high operational reliability and offers for the daily use completely adequate security against unintentional actuation.

In a particularly advantageous embodiment of the invention, has the wall part forming the protective element has a port set which is arranged in front of the outlet opening of the nozzle. As a result, the protective element does not only prevent the valve from being operated before the protective element is removed, it also covers the nozzle so that aerosol substance is caught in the event that the valve is damaged by any manufacturing defects or the packaging error should partially open during transport or storage. The nozzle covering process is at the same time an indicator for whether any Substance leaked from the nozzle before the protective element was removed.

For particularly convenient, convenient actuation for removing the wall part forming the protective element, in the frame According to the invention, the wall part has a freely accessible edge which is arranged at a sufficiently large distance from the actuating button in order to break it off with the lingers on diesel to be able to capture free edge.
