Description

The invention relates to a kit for a cap closure for containers with a threaded neck.

There are known closures which consist of a metal cap which has an internal thread and which can be turned on the corresponding container. There are also closures known that on their have lower edge webs and are connected to a ring via these webs. If such a closure is attached to a container neck, when the metal closure is unscrewed, the webs broken open and the ring remains on the neck of the container. Such a closure is called a pilverproof closure designated. It makes it possible to monitor the first time a container is opened. When the closure is opened for the first time, the breaking of the webs indicates that the container is has already been opened. Such a closure is used for both spirits and soft drinks also used in medicine containers.

There are also child-resistant closures that consist of two interlocking caps. The inner metal cap has an outward-facing knurling on its upper edge, whereas the outer cap its upper inner edge has a knurling.

If the outer cap is rotated, it slides loosely over the inner metal closure and the closed containers will not be opened. However, if you exert pressure on the outer cap so the inner knurling of the outer cap engages with the knurling of the inner cap and the closure will be opened.

In this known closure, the inner cap is made of metal, in particular aluminum. The outer cap is made of an elastic material so that it fits into a Pressure on their top surface can expand and then return to their original shape got back. After prolonged use of this fastener there is a risk that the elasticity the outer cap decreases and thus the knurling of the outer cap always into the knurling of the inner one Cap engages and the closure is therefore no longer childproof.

The object on which the present invention is based is to propose a kit for a cap closure for containers with a threaded neck, that is childproof, that allows you to control the opening of the container for the first time, and the

This object is achieved in that the kit consists of two caps that one Cap has elevations on its top surface, has a circumferential bead and its lower edge over Web is connected to a ring that the other cap on its inner bottom surface facing downwards Has bumps and its lower edge is bent inwards that this cap as an outer cap in such a way over the first cap as an inner cap that the curved lower edge of the outer Cap under the bead of the inner cap engages that the elevations of the outer cap only between the bumps of the inner cap get when a pressure is exerted on the top surface of the outer cap will.

The first cap is placed on the threaded neck of a container and in a manner known per se The thread is rolled on and the lower edge is beaded. • Then the second cap is placed over the first Cap attached so that its curved lower edge engages under the bead of the inner cap and the cap closure is formed.

Due to its special arrangement, this lock enables control over an unwanted one Ensure opening of the container. The one connected to the lower edge of the inner cap via webs The ring remains on the container neck when the closure is opened by breaking the webs. However, this opening of the closure can only take place if the top surface of the outer cap a pressure is exerted and at the same time the shutter is rotated. By securing the Closure, it is ensured to an increased extent that a container cannot be opened by children can. However, it is also possible to control the opening of a container for the first time. at Many liquids, especially in pharmaceuticals, it is desirable that such a multiple Securing the lock is possible in a simple manner. The ring remaining on the neck of the container shows indicates that the lid of this container has already been opened.

If the lock is on a. Container so When the outer cap is rotated, it slides along the inner cap without taking this inner cap with it. Attaches to the top surface of the outer cap

According to a particularly preferred embodiment of the present invention, the elevations are inner or outer cap in an annular area, the elevations are the outer Cap designed as radially extending teeth and each elevation of the inner cap is through a formed upwardly curved edge of a radially extending slot in the top surface of the inner cap.

According to these particularly preferred embodiments the teeth arranged in the outer flap only then grip between the slots on the Inner cap top surface when pressure is applied to the outer cap top surface. It is guaranteed

ensures that, even after prolonged use, the outer cap can only be rotated together with the inner cap when on the top surface of the outer Pressure is exerted on the cap.

The manufacture of the inner cap is particularly simple in this particularly preferred embodiment, because by simply making numerous slots the desired elevations in the top surface of the inner Cap can be generated. One edge of each slot is bent upwards and thus forms the desired elevation.

According to a particularly preferred embodiment and the elevations of the inner cap or the outer cap are arranged in an annular area, the elevations of the outer cap are designed as triangles with a straight or curved base and each elevation of the inner cap is embossed into the top surface of the inner cap and faces towards the bottom surface of the outer cap. The shape of the elevations of both the inner and the outer cap can be designed differently.

According to a preferred embodiment of the present Invention, the bottom surface of the inner cap is covered with a sealing washer that is gas-permeable and is impermeable to liquids. This particularly preferred embodiment enables escape a gas through the sealing washer and the slots in the bottom surface of the inner cap, whereby a further safeguarding of the containers closed with the closure is guaranteed.

Unintentional bursting of the container or puffing up plastic containers as a result of excessive gas development will be avoided as a result.

According to a further particularly preferred embodiment, the inner cap is made of aluminum and the outer cap made of plastic. The outer cap is produced, for example, by injection molding. Here the desired teeth or elevations can be attached to the outer cap in a simple manner and at the same time the desired structure on the inner surface. As a result of the manufacture of the inner cap made of aluminum is a particularly easy way of attaching the upturned edges of the slots in the Top surface of the inner cap possible.
