Description

You invention relates to a cap and a cap Push button for an aerosol container and a method of assembling the two.

In the aerosol canister business, some setts are used Time a cap with a valve button to improve the appearance of the container, to make the container stackable, to protect it against unintentional operation, to enable the installation of devices to prevent unauthorized use, to instruct the consumer in the use of the container, etc. »Is accepted.

nozzle contains. It is customary to do this to bring about between the push button and the cap that both are connected to each other before they are attached to the aerosol container.

However, aligning the cap relative to the push button is quite tedious. Therefor are either made of one piece Snap fasteners and caps required, or a special slow-acting device must be used to perform this process.

Yersuohe has also undertaken these difficulties to fix, however, they have not yet led to a usable result. In U.S. Patent 3,407,975 e.g. B. has the push button with a groove an inlet duct and the Eappe a bar in their im Floor lying opening. When this opening is pushed over the push button, the bar meets the upper surface of the push button. One must therefore use brushes to turn the cap relative to the push button until the ledge goes into the grain, the ledge into the Groove leads into it. At this point the parts are aligned and connected to one another. Then the Cap pressed down and on the aerosol container Börteln, for example, attached.

The aim of the present invention is to provide a self-aligning combination, consisting of

a push button and an attachment cap, which can be quickly stripped out of each other without being externally, for example by brushing, a torque must be exerted.

Another feature is the creation of a self-aligning slip-on cap and push button for an aerosol container in which the cap aligns itself automatically with the push button without a goal orientation is required, simply by the fact that the " Cap is placed on the push button. The push button and cap combination is secure after alignment connected with each other. The cap can be easily and quickly adjusted after being aligned with the push button of the aerosol container is to be pressed onto this in order to then snap into place «

This is achieved by cutting off the upper surface of the push button at an optimal angle, so that the cap can rest on this surface and rotate, but still be slightly depressed |

can. .

The cap has a central, cylindrical opening on, in which a ledge-forming elevation is arranged at its upper end, and the push button has a vertical one Hat in its side wall, into which this ledge enters as well as a smooth surface and at least in his Edge part has a greater width than the strip wide · V and is inclined at an angle of 10 to 20 °. ■

When assembling the cap of the container, the cap is placed on the push button without pre-orientation, such that the push button lies within the central opening and the bar rests on the surface of the same. Under the force of gravity, the cap then slides down and rotates down onto the surface of the push button until the strip enters the groove. If that's the pail, then the cap and snap are right together aligned. Then the cap is pushed down and snaps over the end of the mounting collar of the aerosol valve on the container by means of a rim arranged on the inside of the cap.

The invention will now be explained in more detail with reference to the drawing, which shows an exemplary embodiment.

Pig. 5 shows a representation, partly in section, of the push button of FIGS. 1 to 4.

In the drawing is in Pig. 1 and 2 show an aerosol container cap 10 which is not aligned with a push button 12 of an aerosol container. The push button is connected in the usual manner to a valve stem 14 of an aerosol valve. He may be releasable, but also firmly connected to the similar valve stem. The valve is fastened within the opening of the container 16 by crimping at 18 in the usual fastening cap which generally forms a veil of the aerosol valve.

The upper surface of the cap is provided with a recess 20 for the spray jet and a recess 22 for the actuating finger. The recess 20 for the spray jet forms an opening for the contents of the aerosol container bindurohge long, and the recess for the finger is designed to support the finger There is a stop and a lighter depression of the push button enables. To ensure the use of the aerosol container To make it even easier, there is an arrow 24 in the finger hole molded, which indicates the spray direction.

preferably on the longitudinal center line of the recesses for the spray jet and the actuating finger, although it too can be oriented differently.

To make better contact between the bar and the push button and to cause the bar to fall excessive jiggling of the cap during assembly To prevent this, the diameter of the central opening 26 is only slightly larger than the diameter of the push button, and the length of the side wall of the opening is substantially the same as the length of the push button. Concentric to The peripheral wall of the cylindrical opening 26 is an annular one Edge 30 arranged, which is slightly smaller in diameter than that of the border 18, so that when Niederdrüoken there is a frictional bond between the rim and the flare that secures the cap to the container holds on. The outer wall of the cap is dimensioned such that when the cap is depressed this either with the top of the container is in line or within the rim of the container.

The push button is substantially cylindrical and contains the usual bore 32 with a nozzle through which the aerosol leaves the container when the push button is depressed leaves. Diametrically opposite this nozzle opening, a vertically running groove 34 is worked into the side wall, although this groove can also be arranged at a different location. This groove 34 is slightly larger than

the ledge 28 that interacts with it. So that the bar slide on the top of the snap fastener and into the hat can occur, regardless of the position in which the cap is on the push button, is the upper surface 36 of the push button - at least in its edge part in the The extent of the groin is smooth and at an angle between 10 and inclined 20 ° downwards. At a larger angle, | of course the bar is even better and easier on the push button slide along, but as the size of the angle increases, it becomes more difficult to depress the push button for it This creates a resulting movement in which the push button both downwards, but also essentially afterwards is pushed forward, which creates a smaller force vector in the vertical direction.

To align and assemble the cap and push button, the cap is placed on the push button without pre-orientation 12 placed in such a way that the bar 28 rests on the upper surface of the button, like the one from Eig. 1 and 2. Under the influence of gravity alone without additional Torques acting on the cap or the container, the cap slides with the ledge 28 on top of the Push button down until the bar 28 enters the hat 34, As the clearance between the cap and the Button is not very large, the canopy will not swing excessively as it slides down. Although it is not necessary *

dig is, the container can, if desired, be intentionally made to vibrate or via the filling and Assembly machines are vibrated so that this sliding movement is accelerated. 'If the bar 28 lies in the groove 34, the parts are aligned with one another and the outlet nozzle lies on the longitudinal center line of the Spray jet and recess recesses, after so the alignment is established, the cap is depressed until the rim 30 snaps over the flare 18. Through this the cap is firmly attached to the container.

From the above description it appears that in this way the cap is automatic without any pre-orientation and is aligned without the use of additional rotary movements, for example by means of brushing. The inclined The surface of the push button allows a slight depression, the same and also a sliding down of the cap. The lightness and reliability of this embodiment is particularly economical in the case of a single mass-produced article.

The groove 34 in the push button opens there at an angle running top 36 of the push button, where this has its deepest point.
