To effect the spray button and the spray opening in the attachment cap. This is achieved in that the attachment cap is placed over the spray button in such a way that the spring is opened the inclined top surface or face of the spray button rests on. The attachment cap then slides through the force of gravity and rotates relative to the spray button until the spring fits into the vertical groove formed on the spray button falls.

The invention relates to a cap-spray head arrangement for an aerosol container and a method for automatically aligning the attachment cap with a Another feature to prevent the spray button from getting stuck during its subsequent use.

More recently in the aerosol market there is the use of an overhead cap with a valve or spray button for improving the appearance of the aerosol container or the spray container or the spray can is very popular In order to enable stacking, to prevent accidental actuation, the attachment of (thief) security devices to enable the user to be instructed in the use of the can and for similar reasons.

Since overcaps are usually shaped to indicate the direction in which the aerosol contents are sprayed they must be aligned or aligned with the spray button. This is usually done before made of attachment to the container. With the conventional method of alignment, the attachment cap and the spray buttons are usually fixed against each other before they are attached to the spray can.

Techniques for aligning the cap in Bezuf; on the spray button were unnecessarily cumbersome. They required one-piece molded cap spray button com-

Blue nations or extra provisions with an associated greater amount of time needed to effect alignment * Attempts to improve these "techniques have recently had little success or no significant improvement," for example in the US patent 3 407 975 the spray button has a groove with a filler guide, and the attachment cap has a tongue in its opening that accommodates the spray button. If this central opening is placed over the spray button, then the spring rests on the upper end surface of the spray button. Brushes are then used to rotate the Aufsetzkappe'relative to the spray button until the spring enters the insertion guide, which guides each of the Aufsatzkappe into the groove and in this way aligns and fixes the parts against each other. The overcap is then depressed and clamped onto the spray container.

■ If the spray button of such a construction sprays through the wall of the cap, another problem arises, namely it often happens that the spray button gets stuck during assembly or operation * It seems a natural tendency during To insist on use, push the spray button both down and forward, which causes the spray button slides forward under the upper edge of the spray opening,! As a result, the stuck front part of the Spray button a continuous actuation or a continuous depressing of the spray button, which of course is undesirable is. '·

The object of the invention is therefore to create a self-aligning attachment cap which can become dead against an aerosol distributor and spray button without the aid of rotating forces acting on nuts, for example brushes.

Spray button can be aligned without you having to use a specific one beforehand Location is granted; it should be quickly and easily aligned simply by placing it on the spray button can be securely attached to the manifold when aligned. This is supposed to be done easily by clamping the attachment cap can be done on the spray container after aligning; the spray button should also be used during assembly or its actuation cannot be held by the spray opening in the attachment cap or become stuck on it can.

Another object of the invention is to provide an economical and very reliable method of alignment an attachment cap opposite the spray button on an aerosol or spray container. More details about the invention The task that has been set and solved can be found in the following description.

The object on which the invention is based is achieved by an attachment cap with a spray button central opening. A spring protrudes from and engages the upper rear portion of the opening a spray button which has a vertical groove formed in its side wall. A Z-shaped ring protrusion is formed on the boundary wall of the central opening, whereby the lower portion of the engagement between the tongue and groove maintains; the upper portion prevents the spray button from getting caught on a spray opening in the side wall of the attachment cap.

When the attachment cap is attached to the spray container with the valve arranged in it, the attachment cap is without align them beforehand, placed over the previously assembled spray button, so that the spray button is within the central opening is located. The spring rests on the upper one

309809/0235

End surface or top surface of the spray button. As a result of the force of gravity, the attachment cap then slides while rotating the top surface until the tongue enters the groove. The cap and spray button are then in order aligned. Then the attachment cap is pressed down in order to place it on the edge mount "or the rim of the mounting cap clamp the valve of the spray canister.

In this position, the lower part of the spray button engages and prevents the Z-shaped projection a tumbling of the spray button around the vertical axis, and at the same time holds back the front part of the spray button, whereby the spray button does not cross the plane of the spray opening when it is actuated and thus does not get stuck can.

The invention is described in more detail below with reference to the drawings. These show in:

FIG. 1 shows a plan view of the attachment cap according to the invention with a spray button in the aligned position;

FIG. 2 shows a cross section through the attachment cap and spray button in the plane 2-2 of FIG. 1;

The same reference symbols denote in the various Views of the drawings like parts.

In detail, Figure 1 shows a dome-shaped aerosol attachment cap 10 and a spray button 12, which on a Sprays) he holds 14 are mounted. The spray button 12 is typically shown as being attached to the valve stem 16 of an aerosol or spray valve. He can according to the usual Practice either releasably attached to valve stem 16 or integral therewith. The valve is in the Opening of the container 14 with the help of a bent flange 18 attached to the standard mounting cap 19 ', the usually forms part of an aerosol or spray valve.

The front of the attachment cap contains a recess 20 for guiding the spray jet with an inner one Spray opening 22 located at the end. The top of the attachment cap contains an indentation 24 for receiving or guiding a finger. The recess 20 for guiding the spray jet and the spray opening 22 form an open one Passage for sprayed aerosol, while the indentation for the finger is a saddle-like pad for the finger of the operator and makes it easier to depress the spray button. This training of the recess 20 for the guidance of the spray jet and the indentation 24 for guiding a finger facilitates a quick operation for the user Determine the direction of spray. To make it even easier to determine this spray direction, the spray button an arrow 26 may be formed.

To accommodate the spray button 12, the attachment cap 10 is provided with a central opening 28. In the upper end of this opening protrudes a narrow projection, which is referred to as spring 30 and is designed so that he can ride on the inclined top surface of the spray button.

309809/0235

The spring 30 is preferably along the longitudinal center line of the recess for the spray jet guide and the indentation for the pinger guide arranged; however, it can also be arranged in a different manner, as shown in FIG from the following description.

A Z-shaped step or protrusion 32 is around the spray button receiving opening 28 arranged. A splash 34 arranged around the lower circumference of the spray button 12 works effectively with the · ring projection 32 together, in such a way that the foremost Part of the spray button 12 backwards away from the vertical plane tangent to the spray opening 22 and in the downward direction is held up.

To ensure that the spring 30 comes into contact with the spray button 12 ensure and prevent that the spring 30 as a result of excessive thawing of the cap 10 during the When the assembly drops, "the diameter of the central opening 28 is only slightly larger than the diameter at least part of the spray button 12, and the length of the side wall of the opening is substantially the same as the length of the spray button 12. ■

An annular rim mount is concentric with the surrounding or annular side wall of the opening 28 36 arranged, which is slightly smaller in diameter than the beaded edge 18, so that when pressed on this is, friction generated between the rim and the beaded edge holds the cap on the container. The outer The wall of the attachment cap is such that when the cap is depressed, it is either flush with the top of the container is, or oich from the rim of the container inwards extends.

309809/0235

Typically, the spray button 12 is essentially cylindrical and has the usual passage with an opening for distributing or spraying the aerosol content, if the spray button 12 is depressed. The spray opening diametrically arranged opposite one another is a vertical groove 38 machined into the side wall of the spray button. However a different arrangement of the groove is also possible. The groove 38 is slightly larger than the tongue 30 that engages it. To allow the spring 30 to slide around on the spray button 12 and into the groove 38 independently of the the alignment of the attachment cap 10 placed on the spray button 12 can occur, is the top surface of the spray button 12 or at least the edge portion sufficient to accommodate the spring 30 is smooth and at an angle of Inclined 10 - 20 ° downwards. Of course, at a steeper angle, the spring 30 could hit the spray button even faster 12 slide down; however, if the angle is steeper Depressing the spray button is more difficult, since the resulting movement is essentially both a forward push also results in a downward push. This creates a smaller force vector in the vertical direction generated.

When aligning the attachment cap 10 with respect to the spray button 12 or its assembly with this, the Attachment cap 10 is placed on the spray button 12 without prior alignment in such a way that the spring 30 is on the top surface of the spray button rides. By gravity then rides the attachment cap 10 without applying additional rotational forces to the attachment cap 10 or the container 14 on the upper one Top surface of the spray button 12 down until the spring 30 slides into the groove 38. Because of the small play between the spray button 12 and the Z-shaped ring projection 32 the Aufsetzkappe 10 stumbles the Aufsetzkappe not excessively when sliding down on the inclined plane. Albeit this

309809/0235

is not necessary, the container 14 may be intentionally vibrated or vibrated by the action of the filing machine to accelerate this movement, if desired. When the tongue 30 is in the groove 38, the parts are aligned with one another. In the aligned state, the spray opening is centered or aligned with respect to the longitudinal center line of the recess 20 for guiding the spray jet with the opening 22 and the recess 24 for guiding a finger. After the cap 10 has been aligned, it is pressed down until the
Edge mount 36 engages over the flanged edge 18 of the container. As a result, the attachment cap 10 is firmly attached to the container 14.

The novel Z-shaped step or protrusion 32 creates a lower diameter in the central opening 28, which is small enough to hold the hat 38 and spring in engagement, and it creates an upper one Diameter that is large enough to prevent it from getting caught the spray button at the spray opening 22 to prevent.

It should be noted that when the cap 10 is mounted, its vertical dimension extends over the top surface of the
Spray button 12 out / extends, whereby the spray button 12 is protected from inadvertent actuation.

The invention creates a new, self
created aligning, non-sticking cap-spray button arrangement for aerosol or spray container. The attachment cap aligns itself automatically without being aligned beforehand and without additional rotating elements such as brushes. The ease, speed and reliability of the alignment make this method special
economically.
