Description

The invention relates to a color marking with integrated spray protection for aerosol cans with attachable spray head.

Aerosol cans with attachable spray heads are well known in the art. They are used both in the technical field, for example for building skins and paints, in the artistic field, for example for paints, in the cosmetic sector, for example for deodorants, hair sprays or shaving foams, or in the medical field, for example for spray dressings or disinfectants.

The spray device of aerosol cans must be regularly protected by a spray against unauthorized or unintentional operation. Such a spray protection on the one hand prevent inadvertent spraying by accidentally pressing the spray head, on the other hand but just the unauthorized spraying, for example, as a test before buying, can be prevented. Thus, unauthorized spraying prior to purchase not only causes the environment to be disturbed or destroyed by odors or colors, but also prevents appropriately used products from being resold as they are no longer new and appropriately filled. The financial damage thus includes, where appropriate, in addition to the repair and the replacement of the used product.

Last but not least, it should be possible for the potential buyer to differentiate a used product from an unused product by appropriate measures. This can for example be done in a simple manner by the fact that the release of the spray protection leaves an easily recognizable track and is irreversible at least with respect to the original state.

To solve this known problem, different solutions are proposed in the prior art. The US 3,606,106 B For example, proposes to extend the spray head to the valve plate by a spacer which is releasably attached to the spray head, so that a pressing of the spray head without the previous irreversible release of the spacer is impossible.

The EP 0 945 366 B1 describes a spray fuse in which a support assembly by pressing or gluing force or positively connected to the valve plate, that is blocked by this movement of the spray head for actuating the spray valve. The support assembly is detachable from the valve plate only under pressure.

The DE 20 2006 017 045 U1 discloses a spray fuse whose body has a central bore for receiving the riser and which can be positively and / or non-positively inserted into the interior of the spray head.

Another known problem is to provide the aerosol cans, especially if they are filled with paints, economically meaningful with a color marking corresponding to the can contents. The aim is to produce an aerosol can including lid and label uniformly for all sorts of colors and to be able to subsequently attach a color mark also reversible if necessary.

Appropriate solutions are known in the art, especially in the form of ring collars (also known as donut ), which are usually attached or clamped at a point of the dome of the aerosol can. Such solutions describe, for example, the DE 2132384 A or the DE 101 26 961 A1 , Various similar proposals are disclosed in further applications.

A disadvantage of the prior art is that the previously known solutions for spray safety and color marking must be mounted in the course of production in two separate steps.

In this respect, it is an object of the present invention to provide an alternative system which does not have the mentioned disadvantages and which also serves as a color marking and as a spray protection.

It is also an object of the invention that the corresponding system in one step as a workpiece is easy to install.

A further object of the present invention is to provide a spray protection whose removal leaves irreversible traces and thus serves to identify a prior use, which, however, can be used again at any time for renewed securing of the spray head.

This object is achieved by an invention having the features of claim 1. Advantageous embodiments are the subject matter of the dependent claims. It should be noted that the features listed individually in the claims can also be combined with one another in any desired and technologically sensible manner and thus show further embodiments of the invention.

An inventive color marking with integrated spray protection for aerosol spray cans comprises at least one substantially annular outer and one substantially annular inner element. The elements are arranged concentrically to each other and releasably connected to each other via at least one connecting element.

The annular outer member is substantially for attachment and color marking and includes an annular body, an inner opening, a inner diameter and an outer diameter. The annular outer element is positively or non-positively connected to the dome of an aerosol spray can. The connection can preferably take place at the transition between the valve disk and the dome and / or at the transition between the dome and the can body. These transitions are often executed as crimped seams. Particularly preferred is the connection to the crimped seam between the valve disk and the dome, but embodiments are also conceivable in which the fixing of the annular outer element takes place at the transition from dome to can body.

However, in this preferred embodiment, the diameter of the inner opening of the annular outer member is greater than the outer diameter of the valve disk smaller than the outer diameter of the dome of the can. In this case, the annular outer element comprises at least one latching element which protrudes into the inner opening and which reduces the diameter of the inner opening such that the diameter of the inner opening of the annular outer element is at least in the region of the latching element so much smaller than the outer diameter the valve disk, that the annular outer member is slipped over the valve disk and the latching element engages below the outer seam between the valve disk and dome. As a result, the annular outer element between the valve disk and Dom is latched. Preferred in this embodiment are a plurality of latching elements, in particular three to five latching elements, wherein embodiments are conceivable in which the latching element is designed as a continuous inner projection.

In a further preferred embodiment, the annular outer element comprises a bridging element. The bridging element adjoins the inner opening of the annular outer member and is formed substantially hollow cylindrical. In this case, the diameter of the inner opening of the bridging element is substantially identical to the diameter of the inner opening of the annular outer member. The bridging element substantially bridges the height of the crimped edge of the valve disk. Preferably, the annular outer element is made seamlessly with the bridging element and forms with he together the ring body, but there are also composite embodiments conceivable that are connected in a manner known to those skilled.

The latching elements can alternatively originate in this embodiment with bridging element from the inside of the bridging element and protrude in the manner described above in the inner opening of the bridging element. In this case, the annular outer element is pushed so far over the outer edge of the valve disk until the at least one latching element engages under the edge.

The annular inner element essentially serves as a spray protection. It is separably connected via at least one connecting element with the annular outer element. The inner element may, but need not be positively or non-positively introduced into the valve plate, since the support is substantially via the connecting elements with the outer element or by the plugged spray head.

In a preferred embodiment, the inner element is substantially shaped so that it can be introduced into the valve disk and can receive the spray head. For this purpose, the annular inner element is substantially hollow cylindrical shaped with an inner and an outer diameter and with a first and a second end. The inner diameter of the hollow cylinder is larger than the outer diameter of the spray head and the outer diameter of the hollow cylinder is smaller than the inner diameter of the valve disk.

The first lower end of the annular inner member includes a spacer fixedly connected to the inner member. Preferably, the inner member and the spacer are made in one piece. The spacer is adapted to block the trigger path of the spray head for actuating the spray valve such that successful actuation of the spray head is impossible without prior removal of the spacer and / or the annular inner member. The spacer can be off individual struts or even in the manner of a washer be formed as a continuous inward-facing projection.

The second, upper end of the annular inner member comprises in a preferred embodiment, a substantially horizontally outwardly extending continuous projection which projects beyond the upper edge of the valve disc at least partially in the direction of the outer annular member and so the gap between the inner and the outer annular Element at least reduced in these places. The annular inner member is separably connected to the annular outer member via at least one connecting member. Preferred is an embodiment in which the second end of the inner element and the upper end of the bridging element terminate on a plane just above the valve disk, so that only a minimal gap between these two elements is to be bridged by the connecting elements. The connecting elements correspondingly extend from the upper end of the outer element to the projection of the inner element.

Preferred is an embodiment with a plurality of connecting elements, in particular with three to five connecting elements. The fasteners may also include break points for easier separation. Also conceivable are embodiments in which both elements are connected to each other substantially continuously above the upper edge of the valve plate, for example by a further widening of the previously described projection at the upper end of the inner element, which then serves as a connecting element and connects the inner and outer annular elements. The projection may then be provided for ease of separation, for example, with a line of weakness or perforation between the two annular elements.

For easier separation of the inner member from the outer member, the inner member may comprise a tab or a simple projection, for example as an extension of the already existing projection, at its upper end.

Essential for the inventive idea is in addition to the reusability of the inner annular element as a spray protection that the annular elements are connected in each case with each other and can be mounted in one piece on the spray can, preferably by snapping below the valve disk. It is preferable for all embodiments, a one-piece production of color coding according to the invention with integrated spray protection, even if embodiments are conceivable in which parts of the invention color mark with integrated spray protection can be made individually and then joined together.

According to the concept of the invention, embodiments are also conceivable in which the shape of the inner element is substantially reduced to the shape of a washer, the outer diameter of which is smaller than the inner diameter of the valve disk and the diameter of the inner opening allows introduction into the valve disk. The thickness of a correspondingly reduced inner element then corresponds to the length of the triggering path of the spray head to be blocked. Accordingly, the connecting elements are guided substantially from the outer edge of the inner element to the outer element. In this respect, these connecting elements can also be seen as a reduction of the previously described as a hollow cylinder portion of the inner element.

Likewise, the annular outer element is individually designed very flexible. Thus, the shape of this outer element of a cuff that covers the dome of the spray more or less completely, to a rather narrow ring, which essentially serves only the attachment range.

Since the outer element according to the invention also serves the color marking, a rather cuff-shaped configuration of the outer element in the sense of a good recognizability of the color marking is to be preferred. The individual design of the sleeve are then in the functional framework, however, hardly limit to set, especially not if the attachment of the outer member substantially via the bridging element takes place by snapping below the valve disk.

The assembly of the paint marking according to the invention with spray protection is essentially done by this is mounted on the spray can in particular on the dome of the box, while the spray head is not mounted. The spray head can be mounted after installation on the can and in particular on the spray insert, without the attachment of a triggering of the spray valve must be feared because the spray is already mounted.

The removal of the spray protection takes place by disassembling the spray head and then separating the inner element from the outer element and removing it from the valve disk. Subsequently, the spray head can be used again. The spray can is now ready for use. Even if the inner element has been separated from the outer element, it does not lose its functionality as a spray protection and can be used again at any time for spray protection by the spray head removed again, the spray protection used and the spray head is then plugged back. Since the first time removal of the spray, so the separation of the inner member from the outer element, the connecting elements are destroyed, a new spray can already be distinguished on the basis of undamaged fasteners externally of a used aerosol can in which the fasteners are destroyed.

The invention and the technical environment will be explained in more detail with reference to FIGS. It should be noted that the figures show a particularly preferred embodiment of the invention. However, the invention is not limited to the embodiment shown. In particular, the invention includes, as far as is technically feasible, any combination of the technical features that are listed in the claims or described in the description as being relevant to the invention.

FIG. 1 shows a top view of a preferred embodiment of the invention color mark with integrated spray safety 1 with an annular outer member 2 and an annular inner member 3, wherein the inner member 3 substantially serves as a spray protection and the outer element 2 substantially as a color marking and attachment means , In the illustrated preferred embodiment, the outer member 2 is divided into an outer sleeve 7 and an inner bridging element 6. The sleeve 7 substantially covers the dome of the spray can and serves as a color marking for identifying the content in the can and in particular its hues , Their design is correspondingly flexible in the functional context possible and almost free both in terms of the surface design and on the edge design in particular of the outer edge, since the outer edge in the illustrated embodiment fulfills no function as an attachment means and can also be used decoratively.

The bridging element 6 is mainly used to bridge the height of the valve disk from the cathedral of the box to the upper edge of the valve disk. From the upper edge of the bridging element 6, the at least one connecting element 4 extends between the outer 2 and the inner element 3.

The annular inner element 3 serves in the illustrated embodiment substantially as a spray protection. It is substantially hollow cylindrical in shape and suitable to receive the spray head. At the lower edge of the inner member 3 is a spacer 5 which is adapted to block the triggering path of the spray head for actuating the valve such that successful actuation of the spray head without prior removal of the annular element is not possible. Preferably, the spacer 5 and the inner member 3 are made in one piece.

The upper edge of the inner element 3 may comprise a substantially horizontally outwardly facing projection which at least partially covers the upper edge of the valve disk. As a result, the gap between the outer 2 and inner element 3 is reduced at the appropriate places. The outer 2 and inner element 3 are interconnected via at least one connecting element 4, in the illustrated preferred embodiment via three connecting elements 4. The connecting elements 4 extend from the upper edge of the bridging element 6 to the outer edge of the projection 3 a of the inner element 3.

For easy separation of the inner element 3 from the outer element 2, the inner element 3 may have a separating aid 8, preferably at the upper edge. The separation aid 8 may be formed, for example, as an extension of the projection 3a or as a tab.

FIG. 2 shows the bottom of the preferred embodiment according to FIG. 1 , Evident is the spacer 5, which blocks the triggering of the spray head so that the spray valve can not be triggered by the spray head. Also to be seen in this view, the latching elements 9, which are located at the transition from sleeve 7 to bridging element 6 and reduce the inner diameter of sleeve 7 or bridging element 6 such that the color marking according to the invention with integrated spray protection 1 by the engagement of the latching elements 9 below the crimped edge of the valve disk on the spray can be latched. The stability of the annular outer element 2 can be increased by stiffening elements 10.

FIG. 3 shows a cross section through a preferred embodiment of the invention color mark with integrated spray safety 1 mounted on the dome 12 of a spray can 14. The outer annular member 2 comprises a cuff-shaped portion 7, which is substantially the dome the spray can 14 covered and can serve for color marking, and a bridging element 6, which bridges substantially the height of the crimped to the dome 12 edge of the valve disk 13 from the lower edge to over the upper edge. The color marking with integrated spray protection 1 is determined by one or more latching elements 9 on the spray can by these engage below the crimped edge of the valve disk 13 between the valve disk 13 and dome 12. The latching elements 9 may be formed as individual elements or as a continuous projection.

The inner annular member 3 is formed substantially hollow cylindrical and includes at its lower end a spacer 5, which blocks the triggering of the spray head (not shown) such that the spray valve can not be triggered by pressing the spray head. The spacer 5 may be formed as shown obliquely angled, but there are also embodiments conceivable in which it goes off at a right angle. The spacer 5 may be formed as a continuous projection, but it may also be formed as a single projection or as a plurality of projections. At its upper edge, the inner annular element 3 comprises a circumferential, outwardly facing projection 3a, on which, for example, the separating aid 8 and the connecting elements 4 are fixed. The connecting elements 4 are connected via predetermined breaking points with the outer annular element 2.
