[0002] FIELD OF APPLICATION AND STATE OF THE ART

[0003] The invention relates to a spray head for an aerosol can. Furthermore, the invention relates to an assembly comprising such a spray head and such an aerosol can.

[0004] TASK AND SOLUTION

[0005] It is an object of the present invention to provide a spray head for an aerosol can and an assembly with such a spray head and with such an aerosol can, which have improved properties.

[0006] This problem is solved by the subject matter of the independent patent claims. Preferred embodiments are the subject matter of the dependent patent claims.

[0007] A spray head according to the invention for an aerosol can, in particular for an arrangement with an aerosol can, has a substantially conical collar with spring prongs for latching onto a, in particular circumferential, rim of a valve plate of the aerosol can. The rim can be a flanged edge. The spray head for the aerosol can is designed in particular for mounting on the aerosol can. The collar can be radially slotted to form the spring prongs. The spring prongs of the collar protrude, for example, radially outward. In this respect, the collar can be latched onto a, in particular complementary, inner circumference of the rim. In the latched state, an, in particular interrupted, outer circumference of the collar can be applied to the inner circumference of the rim.

[0008] The spray head according to the invention has an actuating device. When the collar is engaged on the rim, the actuating device is adjustable from a non-actuating position to an actuating position for actuating the aerosol valve relative to the collar. In particular, the actuating device for actuating the aerosol valve is adjustable toward the collar. The collar can be arranged on a lower edge of the spray head. The actuating device is adjustable from its non-actuating position to its actuating position in an actuating direction of the spray head. Actuating the actuating device can trigger a spraying process. The spraying process can be triggered by manually, in particular axially, pressing the actuating device.The spray head also has a locking device designed to releasably lock the adjustment of the actuating device, particularly in the non-actuated position. Locking the actuating device advantageously prevents unintentional triggering of a spraying process. Unintentional triggering of the spraying process can pose a health hazard and / or lead to contamination. The spring prongs can act as snap hooks to engage the conical collar on the rim of the valve plate. The spring prongs can be locked onto the rim in such a way that, once engaged on the rim, the spray head cannot be removed from the aerosol can without causing damage, particularly without destroying the spring prongs.

[0009] The spray head according to the invention can be held particularly reliably on the aerosol can due to the conical collar with spring prongs. Furthermore, the essentially conical collar enables the spray head to be attached self-centeringly to the rim of the valve plate of the aerosol can. Furthermore, the design of the spray head according to the invention can facilitate production with or from metal. In contrast to plastic conventionally used for spray heads, which can usually only be recycled for energy recovery and not in a material-preserving manner, metal can be remelted for recycling purposes with comparatively little effort while retaining the material. This can have a beneficial effect on the recycling rate of the spray head according to the invention compared to conventional spray heads and thus also on the recycling rate of an arrangement comprising such a spray head and an aerosol can.Reducing the plastic content can therefore have advantages in the processing and recycling of the raw materials. In particular, contamination by plastic residues during the recycling of melted metal components can be avoided or at least reduced.

[0010] In this context, "conical" can refer to the shape of a general truncated cone. Such a general truncated cone can be, for example, a circular truncated cone, but also a truncated pyramid. "Substantially conical" can refer to a shape that deviates from an ideal, generally conical shape, for example, due to manufacturing tolerances and / or interruptions, particularly slots. A lateral surface of a "substantially conical" shape can be curved once or multiple times, particularly doubly, so that an edge of the lateral surface resulting from an axial section can be straight or curved.

[0011] The term "configured" can be used synonymously with the term "designed." The terms "comprises" and "has" can be used synonymously with each other and with the term "has."

[0012] The spray head can be synonymously referred to as the “application head”.

[0013] In an embodiment of the invention, the actuating device comprises an actuating section and a guide section, in particular one that is tapered and / or constricted relative to the actuating section. The locking device comprises a recess with a slot-shaped locking region complementary to the guide section and with a release region that is widened relative to the locking region and coordinated with the actuating section. The actuating device is rotatably adjustable relative to the locking device from a release position for releasing the adjustment of the actuating device into a locking position, in particular a limited one, in order to lock the actuating device in its non-actuated position. In the release position, the actuating section is aligned with the release region along the actuating direction.If the actuating device is locked in its unactuated position, the guide section is arranged in the slot-shaped locking area such that the actuating section overlaps the slot-shaped locking area in a form-fitting manner. This advantageously allows for one-handed operation for locking and unlocking, as well as for operating the actuating device.

[0014] In a further embodiment of the invention, the actuating device comprises a spray nozzle that can be fluidly connected to the aerosol valve of the aerosol can. The locking device has a radial through-opening that is aligned with the spray can when the actuating device is in its release position. In particular, the radial through-opening is aligned with the spray can when the actuating device is in its actuated position. By actuating the actuating device, aerosol can be dispensed, in particular sprayed, from the aerosol can via the spray nozzle and through the through-opening of the locking device.

[0015] In a further embodiment of the invention, the radial through-opening is arranged offset from the spray can if the actuating device is locked in its unactuated position, so that a wall of the locking device enclosing the through-opening at least partially, in particular completely, covers the spray nozzle. Thus, the spray nozzle can be shielded by the wall from the external environment of the spray head or aerosol can. In a further embodiment of the invention, the locking device has a finger recess for actuating the actuating device by means of the locking device. In particular, the finger recess can be designed to complement a human operator's finger. This enables particularly reliable, in particular manual, actuation.

[0016] In a further embodiment of the invention, the locking device has a spring region, in particular an integral one, which is elastically deformable for actuating the actuating device by means of the locking device. The spring region can function as an elastic hinge, for example, in the manner of a film hinge.

[0017] In a further embodiment of the invention, the locking device has a substantially uniform wall thickness. In particular, the locking device is designed as a thin-walled metal part, in particular as a sheet metal part, made of or made of aluminum or steel. "Substantially uniform" in this context can refer to the fact that the wall thickness of the locking device may exhibit deviations of + / - 10%, particularly due to manufacturing tolerances.

[0018] In an alternative embodiment of the invention, the wall thickness can be non-uniform, at least in some areas. The wall thickness can be locally adjusted depending on the load.

[0019] In a further embodiment of the invention, the collar is formed integrally with the locking device. In particular, the locking device is hat-shaped, with the collar forming an integral rim of the hat-shaped locking device. Such a locking device can prove to be particularly mechanically stable.

[0020] In a further, particularly different, embodiment of the invention, the spray head has an intermediate ring that can be mounted on the rim of the valve disk. The collar with spring prongs is integrally formed on the intermediate ring. Providing the collar on the intermediate ring can offer manufacturing and / or assembly advantages.

[0021] In a further embodiment of the invention, the intermediate ring has a substantially uniform wall thickness. In particular, the intermediate ring is formed as a thin-walled metal part, in particular as a sheet metal part, made of or made of aluminum or steel. "Substantially uniform" in this context can refer to the fact that the wall thickness of the intermediate ring can exhibit deviations of + / - 10%, particularly due to manufacturing tolerances.

[0022] In a further embodiment of the invention, the locking device has a substantially conical rim with spring prongs. The intermediate ring has a particularly flanged locking region with an axial undercut, to which the rim is axially locked such that the locking device is rotatable, particularly to a limited extent, relative to the intermediate ring.

[0023] For practical purposes, the ridges of the hem extend radially inward. The ridges of the hem can be referred to as "second" ridges. The ridges of the collar can accordingly be referred to as "first" ridges.

[0024] In a further embodiment of the invention, the spray head has a recess and a projection complementary to the recess. Either the recess on the intermediate ring and the projection on the locking device, or the recess on the locking device and the projection on the intermediate ring, are arranged eccentrically. The actuating device and the locking device are connected to one another in such a way that the actuating device can be rotated, in particular limitedly, relative to the intermediate ring by means of the locking device from the release position of the actuating device into the locking position in order to lock the actuating device in its non-actuated position. In the release position, the recess is aligned with the projection along the actuating direction.When the actuating device is locked in its unactuated position, the recess and the projection are offset from each other transversely to the actuating direction.

[0025] In a further embodiment of the invention, the spring tines, in particular of the collar and alternatively or additionally of the hem, are lamellar. Alternatively or additionally, the spring tines, in particular of each collar and alternatively or additionally of each hem, are arranged along a circumferential direction of the spray head, in particular equidistant from one another, and are angled at an acute angle to an axial direction of the spray head.

[0026] The actuating device expediently comprises a coupling device by means of which the spray nozzle can be fluidly connected to the aerosol valve of the aerosol can. The coupling device can be made of or with a polymer. The spray head is expediently made at least partially or even entirely of metal.

[0027] In a further embodiment of the invention, metallic components of the spray head are manufactured at least partially by primary forming, in particular additively. Alternatively or additionally, metallic components of the spray head are manufactured at least partially by forming. Alternatively or additionally, metallic components of the spray head are manufactured at least partially by separating. Metallic components of the spray head are preferably manufactured at least partially by forming and separating. Metallic components of the spray head can be the actuating device and, alternatively or additionally, the locking device and, alternatively or additionally, the intermediate ring.

[0028] At least one metallic component of the spray head can be made of a metal sheet, in particular of aluminum or steel. Such a sheet can be coated, for example, with tin.

[0029] In a further embodiment of the invention, a gap of the spray head is present between two adjacent spring tines located in the circumferential direction, in particular closest to each other, in particular of the collar and / or the hem. The extent of the gap along the circumferential direction is smaller than the respective extent of the spring tines along the circumferential direction, in particular those directly flanking this gap. The spring tines can thus be wider along the circumferential direction than the gap directly present between any two spring tines. The gap can be axially elongated. The gap can be a slot-shaped recess.

[0030] It is advisable for all spring ridges to be of equal width along the circumferential direction. In particular, alternatively or additionally, all gaps are of equal width along the circumferential direction.

[0031] In a further embodiment of the invention, the spring tines are aligned along the circumferential direction and / or tangentially to the circumferential direction.

[0032] The spring prongs of the substantially conical collar can be advantageously snapped onto the rim of the valve plate of the aerosol can such that the spray head can be positively secured to the aerosol can along the axial direction. The spray head, in particular its spray nozzle, can advantageously be designed to dispense a viscous fluid. Such a viscous fluid can be a gel or a cream. Alternatively or additionally, the spray head, in particular its spray nozzle, can be designed to generate a foam. Such a foam can be shaving foam.

[0033] The arrangement according to the invention comprises a spray head according to the invention as described above. In this respect, the advantages of the spray head according to the invention outlined above also apply to the arrangement according to the invention with such a spray head. The arrangement also comprises an aerosol can with a valve plate having the rim, and with an aerosol valve. The aerosol valve is designed to interact with the valve plate. The collar of the spray head is engaged on the rim of the aerosol can such that the aerosol valve can be actuated by adjusting the actuating device of the spray head from the non-actuated position to the actuated position. By actuating the actuating device, the spraying process can be triggered in order to discharge aerosol from the aerosol can into the external environment of the arrangement.

[0034] In an embodiment of the invention, the spray head and, alternatively or additionally, the valve disk and, alternatively or additionally, the can body of the aerosol can are made with or from a metal, in particular aluminum or steel. At least one valve stem of the aerosol valve can be made from a metal. Advantageously, the arrangement according to the invention can have a higher metal content than conventional arrangements. This can have a beneficial effect on the recycling rate. Alternatively or additionally, the spray head and / or the valve disk and / or the can body are made with or from the same material, in particular metal. The invention can expediently reduce the variety of materials used for the spray head or arrangement compared to conventional spray heads or arrangements.In particular, sorting according to materials can be simplified during recycling or such sorting can even be dispensed with completely.

[0035] The invention advantageously enables the spray head to be securely attached to the valve plate with at least virtually no risk of detachment, while at the same time allowing rotation of the spray head to switch between a locked state and a released state for a spray function of the spray head.

[0049] DETAILED DESCRIPTION OF THE EMBODIMENTS

[0050] A spray head 1 is provided for an aerosol can 50, in particular for attachment to the aerosol can 50. The spray head 1 can be attached to the aerosol can 50 to form an assembly 100. The assembly 100 accordingly comprises the spray head 1 and the aerosol can 50.

[0051] The aerosol can 50 has a valve plate 52 with a rim 51. The rim 51 can be a flanged edge. The rim 51 can be circumferential, in this case completely circumferential. Furthermore, the aerosol can 50 has an aerosol valve 53, which can interact with the valve plate 52 to dispense aerosol. The valve plate 52 is, for example, positively connected to a can body 54 of the aerosol can 50, in particular forming the rim 51.

[0052] In particular, the aerosol can 50 is designed as a container for an aerosol. Additionally or alternatively, the aerosol can 50 can be referred to as an aerosol can or a spray can. Further additionally or alternatively, the aerosol can 50 can be designed to withstand a nominal pressure of 12 bar, in particular 15 bar, in particular 18 bar. The aerosol can be stored together with a propellant gas in a can interior of the aerosol can 50, wherein the can interior is delimited by the valve plate 52 and the can body 54 of the aerosol can 50. By actuating the aerosol valve 53, the can interior can be fluidically connected to an external environment of the arrangement 50 for a spraying process in order to dispense aerosol.

[0053] The spray head 1 has a substantially conical collar 2. The substantially conical collar 2 has spring prongs 3 for engaging the rim 51 of the valve plate 52. The spring prongs 3 of the collar 2 can be "clipped" under a curvature of the valve plate 52 that extends along the rim 51.

[0054] The spray head 1 also has an actuating device 4. When the collar 2 is engaged on the rim 51, the actuating device 4 is adjustable from a non-actuated position to an actuated position relative to the collar 2 in order to actuate the aerosol valve 53. The spraying process can be triggered by actuation. The actuating device 4 is adjustable from its non-actuated position to its actuated position in an actuation direction B of the spray head 1. For example, the actuating device 4 is adjustable from its non-actuated position to its actuated position toward the collar 2.

[0055] The spray head 1 further comprises a locking device 5. The locking device 5 is designed to releasably lock the adjustment of the actuating device 4. For example, the actuating device 4 can be releasably locked in its non-actuated position by means of the locking device 5. The collar 2 can be radially slotted to form the spring tines 3. In this case, the spring tines 3 of the collar 2 protrude radially outward. For example, the collar 2 can be latched or is latched onto an inner circumference of the rim 51. In a latched state, an outer circumference of the collar 2, for example an interrupted one, can be applied to the inner circumference of the rim 51. The rim 51 can be annular.

[0056] The spray head 1 in the present case has an axial direction A, which extends, for example, along the actuation direction B. A radial direction R of the spray head 1 is oriented perpendicular to the axial direction A. A circumferential direction U of the spray head 1 runs in a plane oriented perpendicular to the axial direction A.

[0057] The spring lobes 3 of the collar 2 can, as in the present case, be lamellar. The spring lobes 3 of the collar 2 can be arranged along the circumferential direction U, in particular equidistant from one another. For example, the collar 2 has 5 to 64, in particular 18 to 32, spring lobes 3. The spring lobes 3 of the collar 2 can be angled, for example, at an acute angle, a right angle, or an obtuse angle to the axial direction A. The spring lobes 3 of the collar 2 can be angled by 20° to 150°, in particular by 60° to 90°, relative to the axial direction A.

[0058] Due to their elasticity, the spring prongs 3 of the collar 2 can, on the one hand, enable particularly easy engagement with the rim 51 and, on the other hand, ensure a permanent fit of the spray head 1 on the valve plate 52, whereby a rotatability of the spray head 1 for locking or releasing the spray nozzle 12 can be ensured.

[0059] As can be seen, for example, in Figs. 1 to 3, the actuating device 4 has an actuating section 7 and a guide section 8. The guide section 8 can be tapered relative to the actuating section 7. The actuating section 7 can therefore be thickened relative to the guide section 8. The locking device 5 has a recess 9. The recess 9 comprises a slot-shaped locking region 10 complementary to the guide section 8 and a release region 11 widened relative to the locking region 10 and matched to the actuating section 7. The locking region 10 can run on a circular path extending in the circumferential direction U.The actuating device 4 is rotatably adjustable relative to the locking device 5 from a release position for releasing the adjustment of the actuating device 4 into a locking position, in particular limited, in order to lock the actuating device 4 in its non-actuated position. In the release position, the actuating section 7 is aligned with the release area 11 along the actuating direction B. In the release position, the actuating section 7 can be located exactly above the release area 11, so that the actuating section 7 can be pushed into the release area 11 or through the release area 11 to trigger the spraying process. When the actuating device 4 is locked in its unactuated position, the guide section 8 is arranged in the slot-shaped locking area 10 such that the actuating section 7 overlaps the slot-shaped locking area 10 in a form-fitting manner.If the actuating section 7 is located in overlap with the slot-shaped locking area 10, a depression of the actuating device 4 which triggers the spraying process can be positively prevented.

[0060] For example, the actuating device 4 has a spray can 12 that can be fluidly connected to the aerosol valve 53. The locking device 5 has, for example, a radial through-opening 13 that is aligned with the spray nozzle 12 in the release position of the actuating device 4. In the release position, a spray jet of aerosol can escape unhindered through the radial through-opening 13 after being triggered by pressing down the actuating device 4. In contrast, the radial through-opening 13 can be arranged offset from the spray nozzle 12 when the actuating device 4 is locked in its unactuated position, so that a wall 14 of the locking device 5 enclosing the through-opening 13 covers the spray nozzle 12 at least partially, in this case completely.

[0061] For example, the locking device 5 has a spring region 16. The spring region 16 can be integrally formed. The spring region 16 is elastically deformable for actuating the actuating device 4 by means of the locking device 5. The spring region 16 can function as a hinge. The aerosol valve 53 can be spring-loaded into a blocking position. Since the aerosol valve 53 is coupled to the actuating device 4 in the locked state of the collar 2, the actuating device 4 is self-resetting by the spring preload of the aerosol valve 53 into the non-actuated position.

[0062] For example, the locking device 5 has a substantially uniform wall thickness S. The locking device 5 can be designed as a thin-walled metal part 6. The metal part 6 can be a sheet metal part. The thin-walled metal part 6 can comprise or be made of aluminum or steel. Alternatively, the locking device 5 can have a non-uniform wall thickness in some areas, in particular to integrally reinforce areas of the locking device 5 that are subject to particularly high loads.

[0063] According to Figs. 1 to 3, the collar 2 is, for example, formed integrally with the locking device 5. The locking device 5 can be hat-shaped, with the collar 2 forming an integral rim 17 of the hat-shaped locking device 5.

[0064] 1 to 3, the spray head 1 according to the other embodiments shown has an intermediate ring 18. The intermediate ring 18 can be mounted on the rim 51 of the valve plate 52. The collar 2 is formed integrally on the intermediate ring 18. In the present case, the intermediate ring 18 has a substantially uniform wall thickness S. It is understood that the intermediate ring 18 can alternatively, but in embodiments not shown, also have a non-uniform wall thickness at least in some regions, for example in order to provide integral reinforcements. In the present case, the intermediate ring 18 is designed as a thin-walled metal part 6. The intermediate ring 18 designed as a thin-walled metal part 6 can be a sheet metal part. The thin-walled metal part 6 comprises, for example, aluminum or steel or is made of aluminum or steel.

[0065] In the embodiments according to Figs. 4 to 12, the spray head 1 has a substantially conical rim 19 with spring prongs 3. The intermediate ring 18 has a particularly flanged engagement region 20 with an axial undercut 21. The engagement region 20 can be annular and extend along the circumferential direction U. The rim 19 is axially engaged at the axial undercut 21 such that the locking device 5 is rotatable, particularly to a limited extent, relative to the intermediate ring 18. The spring prongs 3 of the rim 19 protrude, for example, radially inward.

[0066] The spring tines 3 of the seam 19 can be lamellar. The spring tines 3 of the seam 19 can be arranged along the circumferential direction U, in particular equidistant from one another. The seam 19 can have a fewer, equal, or greater number of spring tines 3 than the collar 2. In particular, the number of spring tines 3 of the seam 19 is 12 to 64, preferably 24 to 35. The spring tines 3 of the seam 19 can be set at an acute angle, a right angle, or an obtuse angle to the axial direction A, for example. The spring tines 3 of the seam 19 can be set at 20° to 150°, in particular at 60° to 90°, relative to the axial direction A.

[0067] The spray head 1 in this case has metallic components 24. The metallic components 24 can each be manufactured at least partially by primary forming, in particular additively. Alternatively or additionally, the metallic components 24 can each be manufactured at least partially by forming. Alternatively or additionally, the metallic components 24 can each be manufactured at least partially by separating.

[0068] The actuating device 4 can be a metallic component 24 of the spray head 1. Alternatively or additionally, the locking device 5 can be a metallic component 24 of the spray head 1. Alternatively or additionally, the intermediate ring 18 can be a metallic component 24 of the spray head 1.

[0069] The metallic components 24 can be manufactured, for example, by forming and punching sheet metal, deep drawing, or 3D printing. For example, particularly in the embodiment according to Figs. 10 to 12, at least the locking device 5 can be made from a punched and / or cut and bent sheet metal strip. The locking device 5 can have a finger recess 15 for actuating the actuating device 4 by means of the locking device 5.

[0070] For example, the spray head 1 and / or the valve plate 52 and / or the can body 54 of the aerosol can 50 are made of or from a metal, in particular aluminum or steel. Alternatively or additionally, the spray head 1 and / or the valve plate 52 and / or the can body 54 are made of or from the same material.

[0071] As indicated above, in the embodiments according to Figs. 4 to 12, the locking device 5, in contrast to the embodiment according to Figs. 1 to 3, is not connected directly to the valve plate 52, but rather by means of the intermediate ring 18. The locking region 20 of the intermediate ring 18 can surround a circular inner opening of the intermediate ring 18. The valve stem, in particular a metallic one, of the aerosol valve 53 can be guided through this inner opening.

[0072] 4 to 12, the spray head 1 has a recess 22 and a projection 23 complementary to the recess 22. In this case, the recess 22 is arranged eccentrically, i.e., for example, off-axis, on the intermediate ring 18 and the projection 23 on the locking device 5. It is understood that, conversely, the recess 22 can also be arranged on the locking device 5 and the projection 23 on the intermediate ring 18. In this case, the actuating device 4 and the locking device 5 are connected to one another in such a way that the actuating device 4 can be rotated, in particular limited, relative to the intermediate ring 18 from the release position of the actuating device 4 into the locking position by means of the locking device 5 in order to lock the actuating device 4 in its non-actuated position.In the release position, the recess 22 is aligned with the projection 23 along the actuation direction B. In contrast, the recess 22 and the projection 23 are offset from one another transversely to the actuation direction B when the.

[0073] Actuating device 4 is locked in its unactuated position. The

[0074] 4 to 12, the locking device 5 can therefore only be pressed axially to actuate the actuating device 4 if the recess 22 and the projection 23 are arranged in a common axial alignment. An arcuate segment-shaped recess can be provided below the spray nozzle 12, which corresponds to a tab of the locking device 5. In this way, the rotational adjustability of the locking device 5 relative to the intermediate ring 18 can be limited. For example, between two spring lobes 3 of the collar 2 and / or the seam 19 that are adjacent in the circumferential direction U, there is a gap—in this case axially elongated. In this case, the extent of the respective gap along the circumferential direction U is smaller than the respective extent of the spring lobes 3 along the circumferential direction U.The spring tines 3 can be wider along the circumferential direction U than the gap directly between any two spring tines 3. The collar 2 can be slit, in particular multiple slits, to form gaps between its spring tines 3. The seam 19 can be slit, in particular multiple slits, to form gaps between its spring tines 3.

[0075] For example, all spring tines 3 are of equal width along the circumferential direction U. In this case, all gaps between any two adjacent spring tines 3 are of equal width along the circumferential direction U.
