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 on ent = talking container could be rotated. There are also known closures that have webs on their lower edge have and are connected to a ring via these webs. When such a closure is attached to a container neck is, the webs will break open when you unscrew the metal fastener and the ring remains on the container neck. Such a closure is commonly called a pilfer-proof closure designated. Such a closure makes it possible to control the opening of a container for the first time. When the closure is opened for the first time, the breaking open of the webs indicates that the container has already been opened v / orden is. Such a closure is used both for spirits and soft drinks and for pharmaceutical containers used.

There are also child-resistant closures that consist of two interlocking caps. The inner metal cap has an outward-pointing knurling on its upper edge, whereas the outer cap has a knurling on its upper inner edge Has knurling. If the outer cap is rotated, it slides

Bie loosely over the inner metal seal and the sealed container will not open. But if you practice one Pressure on the outer cap, the inner knurling of the outer cap engages with the knurling of the inner one Cap and the sealed cap is opened.

The object of the present invention is to provide a kit for a cap closure for containers with a threaded neck propose one that is child safe and that allows ί to control the opening of the container for the first time. ■

This object is achieved in that the kit consists of two caps, that a cap on its upper edge has an outwardly pointing knurling, has a circumferential bead and its lower edge has ridges mic a ring is connected, that the other cap has a knurling on its upper inner edge and its lower edge is bent that this cap as an outer cap in such a way over the first cap as an inner cap on the threaded neck of a Is attachable container that its curved lower edge engages under the bead of the inner cap, and that the Knurling of the outer cap only engages the knurling of the inner cap when on the top surface of the outer Pressure is exerted on the cap.

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

Due to its special arrangement, this closure enables control over unintentional opening of the container to ensure. The ring connected to the lower edge of the inner cap via webs remains on the container neck when the closure is opened by breaking the webs. This opening of the closure can only take place, however, when pressure is exerted on the top surface of the outer cap and at the same time the closure is rotated. Through this double securing of the closure, it is guaranteed to a greater extent that a container cannot be opened by children can be. However, it is also possible to control the opening of a container for the first time. With many Liquids, especially pharmaceuticals, it is desirable that such multiple securing of the closure is possible in a simple way. The ring remaining on the neck of the container indicates that the closure of this container has already been opened.

According to a preferred embodiment of the present Invention, the bottom surface of the inner cap has a hole and 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 hole in the bottom surface of the inner cap, whereby a further safeguarding of the container closed with the closure is guaranteed. Unintentional bursting of the container or inflation of plastic containers as a result of excessive gas development is avoided in this way.

The inner cap is advantageously made of aluminum and the outer cap is made of plastic.

The invention will now be explained in more detail with reference to FIGS. 1 and 2:

Figure 1 shows a longitudinal section through half of the outer cap and a top view of one half of the inner cap.

Figure 2 shows a sectional view along the line I-I in Figure 1.

According to Figure 1, there is a kit for a cap closure of two caps 1 and 2, which are drawn interlocking to explain the invention in more detail. The first cap

1 has an outwardly softening knurling 4 on its upper edge. In the lower area, it has a circumferential knurling The bead 5 and its lower edge are connected to a ring 7 via webs 6.

The other cap 2 has a knurling 8 on its upper inner edge and its lower edge 9 is curved. This cap

2 is arranged as an outer cap over the first cap 1 that its curved lower edge 9 under the bead 5 of the first cap 1 engages. The knurling 8 of the outer cap 2 only engages in the knurling 4 of the inner cap 1, when pressure is exerted on the top surface 1o of the outer cap 2. Then the outer cap 2 is spread, as the Bead 5 presses onto inclined surface 3 of outer cap 2. If no pressure acts on the top surface 1o of the outer cap 2, the outer cap 2 is in the state shown in FIG. 1 with respect to the inner cap 1.

If the closure shown in FIG. 1 is on a container _f , the outer cap 2 slides on the inner cap 1 and the container cannot be opened.

· ■ · »Ct

However, if you press on the top surface 1o of the outer cap Z ₉ , the teeth of the knurling 8 engage in the grooves of the knurling 4 and "when you turn the outer cap 2, the inner cap 1 is taken along" When you first perform these steps, the webs 6 are broken and the ring 7 remains on the container, whereas the outer cap 2 can be removed while taking along the inner cap 1. The inner cap 1 cannot fall out of the outer cap 2 because the curved lower edge 9 engages under the bead 5 of the inner cap The outer cap 2 is advantageously made from plastic, whereas the inner cap 1 is made from aluminum.

According to the particularly preferred embodiment shown in FIG the bottom surface 11 of the inner cap 1 has a hole 12. Through this hole can occur in the container Gas escape. However, in order to avoid the escape of liquid, the bottom surface 11 is provided with a Sealing washer 15 covered. This sealing washer 13 is made of a gas-permeable and liquid-impermeable Material made.
