is operated in a vented state.

The invention provides a containment device. the at least part of a lubricant or lubricant compound includes for use in a pneumatic tire and wheel unit, this containment device consisting of a metal container consists, which has a bottom, at least one side wall and a head part ·, the container is with a weakened Zone fitted in the area of the headboard and has such a length, along the axis passing through the bottom and the headboard is that when using the containment device in a tire and wheel assembly the top of the container can be contacted by an inner surface of the assembly when deflated, so that the container breaks along the weakened zone and at least part of the lubricant connection releases.

This weakened zone is preferably not interrupted or continuous.

The container is preferably substantially cylindrical in shape.

The metal from which the container is made is preferably aluminum.

The container may have a weakened zone created by a groove or notch formed in the metal which has a Zone of reduced thickness. The groove may be formed along the perimeter of the container adjacent to its head portion be. Optionally, the container can be provided with a raised part on its head part, with an annular shoulder is formed between the body of the container and the raised portion; the groove is formed and extends in the shoulder

l]

3icli along the edge of the raised part. The shoulder is preferably of the smallest possible extension, ie the difference between the diameter of the raised part and the diameter of the rest of the container is made as small as possible. This is undesirable because in forming the metal container: ^, for example, several j times can be pulled of an aluminum container, the container, and when the extension of the shoulder is large, the force on the raised portion can during use of the container in a deflated tire and wheel unit have the effect that the container turns inside instead of breaking.

Optionally, the container can have a weakened zone thereby be equipped so that the metal is stressed so that a sufficiently weakened part is formed that in use of the container breaks in a deflated wheel unit. For example, the container is preferably formed from sheet metal, a separable bottom fitted into it in a liquid-tight manner is. Under these circumstances, the molding process can be designed that the metal is sufficiently stressed along the desired position of the break line to such an extent, that the metal will break if the necessary force is applied to it in use. If necessary, the basic container could first shaped and annealed, and then further deformed along the location of the break line.

According to the invention, a pneumatic tire and wheel assembly includes at least a containment device as described above.

Preferably the wheel assembly includes a plurality of one-shot devices. The containment devices can be attached to the rim of the wheel assembly. If, building a multitude of containment devices, these devices are preferably mounted on a tape running along the perimeter the fig is provided.

The invention is by way of Au3fülu.-un _e Tsbeisoiels under · reference explained in detail to the drawing: it shows:

Figure 1 is a schematic cross-section of a containment device according to the invention, along the axis passing through the top and bottom parts;

Figure 2 is a view similar to Figure 1 of a modified containment device;

FIG. 5 is an enlarged view of the grooved shown in FIG

or notched part; and

Fig ^.; + A view similar to FIG. 1 of a second deprecated containment device.

j Referring to Fig. 1, there is an containment device j according to the invention from a container 1 with a cylindrical shape, which has a base 2 and a head part 3. The upper part 4 and the base 2 can both be made of sheet metal. Of the upper part 4- in the area of the head part 3, i.e. in this case in small Di distance from the head part 3 along the cylindrical body of the container, mi-c is a weakened zone in the form of erner im essentially V-shaped notch or groove 5, which extends around the entire circumference of the upper part 4-. Of the Bottom 2 is attached to the upper part 4- and the connection is sealed with a sealing closure compound.

In the modification shown in FIGS. 2 and 3, a raised part 7 is also formed on the head part 3, an annular shoulder 3a being formed between the body 3 and the raised part 7, and the groove or washer 5 in the shoulder 3a is arranged and extends around the entire circumference of the raised part 7 around. The included angle Oi of the groove or notch 5 is preferably in the range between 60 ° and 90 °.

In the modification shown in FIG. 4, the head part ό is provided with a weakened zone in that it is stressed enough during molding to easily break during operation of the container 1. As shown, the head part 3 is equipped with a raised ring 8 which creates three stress points at 9. If necessary, the container 1 can be annealed in its head part before the ring is formed.
