Mr. Walter Linder, 731 Plochinqen Thüringer Str. 71 Container for spraying aerosols

The invention relates to a container with an outlet valve for spraying aerosols with an outlet valve above it snap-on lids arranged to protect it, in particular for spraying pharmaceutical and cosmetic products and chemical products.

Such containers for spraying aerosols have a spray valve as an outlet, which can be operated manually especially by pushing, pulling or turning.

Since such containers for spraying aerosols can and must be transported, especially from manufacturing or bottling plant to the dealer and from the consumer himself and there the substances filled in the container Sometimes aggressive or sticky, it is necessary to avoid damage from unintentional actuation of the valve to avoid securing this against such unintentional actuation.

One embodiment of such a container for spraying Aerosols consists, for example, of an aluminum bottle with a rounded shoulder, similar to the familiar shape of a pressurized gas bottle.

A spray valve is arranged on the upper edge of said aluminum bottle. The valve is attached to the aluminum bottle takes place z. B. by crimping.

It is known to press a snap-on cover over the strong bead of the flange to secure the spray valve. However, this protection is only guaranteed if the slip-on lid is firmly in place.

Because of the wide manufacturing tolerances of the outer diameter of the bead, this slip-on lid must have a correspondingly high degree of extensibility exhibit. If the slip-on lid does not have the required high degree of elasticity, the slip-on lid is clamped In the upper tolerance range of the bead, although very large, there is, however, the risk that the slip lid will Overstretching tears and as a result is no longer tight enough. In the lower tolerance range of the bead is through the small difference between the bead diameter and the inside diameter of the slip lid, only a small amount of clamping can be achieved.

The previously known embodiments of the slip lid are simple cylinders, the inside diameter of which must correspond exactly to the outside diameter of the bead, taking into account a certain undersize for the clamping effect.

This simple cylindrical embodiment of the slip lid has the disadvantage of low radial expandability, since it provides effective protection for the spray valve for the slip-on lid a stiff material must be used, which naturally has only little extensibility. So she can compensate only a part of the occurring dimensional deviations of the bead. As a result, it must have a high level of scrap to be worked.

Other known embodiments of the slip lid have on the lower edge of the inside of the cylinder there are narrow webs or knobs that are intended to engage under the bead, however this also means that no greater radial expandability of the cylindrical hooded lid is achieved.

The inventor is based on the task of increasing the radial expandability while at the same time maintaining it the axial rigidity of the slip lid to compensate for the manufacturing tolerances of the outer diameter of the bead and thereby to achieve good clamping in the lower tolerance range of the bead diameter, in the upper tolerance range to avoid the destruction of the slip lid and furthermore to avoid the risk of exceeding or falling below the permissible values Tolerance of the bead diameter to significantly reduce the resulting high production scrap.

The slip lid must therefore have a largely material-independent, elastic construction. This allows the diameter of the slip lid can be chosen so small that it is on the one hand with the smallest incurred in production Bead diameter already brings a good clamping and that on the other hand, it can be expanded radially to a corresponding extent in the case of the largest bead diameters of the flanging without tearing.

According to the invention, this object is achieved in that the slip-on lid is placed one or more times in the tangential direction is interrupted by spaces. This is achieved in that the hooded lid designed in this way is elastically radially can deform outward and adapts to the different bead diameters.

According to a further feature of the invention, the can Slip cover in the tangential direction interrupting spaces are bridged by material bulges. Perfect clamping is achieved through the resilient properties of the bulge in the material.

In a further embodiment of the invention, the slip lid can be used also train in other elastic forms, z. B. as a cylinder that is corrugated in the tangential direction. The curl can be regular or irregular.

Furthermore, the slip lid can be used in cases in which the bead diameter is smaller than the outer diameter of the container, to achieve a pleasing appearance a non-load-bearing, molded outer jacket with about get the same outside diameter as the container.

According to a further feature of the invention, the slip lid can move from its bottom to its open side be tapered conically.

An exemplary embodiment is shown in FIG. 1 and is described in more detail below:

A valve (2) is flanged onto an aluminum bottle (1). The bead (3) of the flange is used to accommodate of the slip lid (4), to which an outer jacket (5) is molded.

Figure 2 shows the plan of a slip lid (4), which is interrupted by two spaces.

Figure 3 shows the plan of a slip lid (4), which is interrupted by several spaces and in which the gaps are bridged by bulges in the material are.

Figure 4 shows the plan of a slip lid (4), the is corrugated in the tangential direction.
