The same reference numbers are used for the same or similar parts in the figures, the corresponding or comparable properties and advantages being achieved even if a repeated description is omitted.
The device 1 has a preferably longish and/or cylindrical and/or rigid container 3 with, especially, a metallic nozzle for discharging of the liquid 2 and a valve 4 which is located preferably on the front of the container 3.
The liquid 2 in the container 3 can either be pressurized or is under pressure. In particular, the container 3 or the liquid 2 contains a suitable propellant, preferably a volatile and/or flammable propellant, compressed gas and/or carbon dioxide.
A spray head 5 is attached to the container 3 or valve 4, especially after filling the container 3 with the liquid 2. In the illustrated embodiment, the spray head 5 is slipped on. However, it can, if necessary, also be detachably attached in some other suitable manner.
The spray head 5, on the dispensing side, has a nozzle 6 for atomization and delivery of the liquid 2. In the illustrated embodiment, the nozzle 6 is made as a separate part, and for example, is inserted subsequently into the spray head 5. However, the nozzle 6 can also be made integrally with the spray head 5, especially can be formed directly as part of it.
The spray head 5 is preferably produced by injection molding from a suitable plastic, and preferably, is made in one piece, optionally, with the exception of the nozzle 6.
When the valve 4 is actuated—in the illustrated embodiment by pressing down the spray head 5—the valve opens 4. The pressurized liquid 2 can flow especially via the ascending line 7 and through the valve 4 and can be delivered via the spray head 5, the liquid 2 emerging through the nozzle 6 and especially being atomized as a spray mist N, as is indicated in
The spray head 5 is preferably made essentially cylindrical or rotationally symmetrical, especially preferably essentially in the shape of the truncated cone.
The spray head 5 is located preferably on the front and/or in the middle on the container 3, especially preferably adjacent to the cover 8 which closes the container 3. Especially preferably, the spray head 5 extends essentially in the axial direction with respect to the lengthwise axis of the container 3.
The cover 8 is conventionally connected to the container 3—especially in the region of one edge 9—for example, by crimping. The cover 8 carries or holds the valve 4 which for its part bears or holds the spray head 5, in the illustrated embodiment.
To actuate the spray head 5, especially to press it down, the spray head 5 is preferably provided with an actuating surface 10 which is made essentially flat or even or smooth and/or is located on the free end of the spray head 5 and/or is tilted slightly to the direction of actuation or the container axis. Especially preferably, the main direction of delivery of the nozzle 6—in the illustrated embodiment in
It is noted that the diameter of the spray head 5 is preferably less than 50%, especially less than 40%, especially essentially 35%, of the diameter of the container 3 or the container edge 9.
The spray head 5 in accordance with the invention has a delivery tube 11 which can be connected alternately on the outlet side to the nozzle 6, especially can be folded to in front of the nozzle 6. By means of the delivery tube 11 the liquid 2 can be delivered alternately as a spray mist N (without a delivery tube 11 directly, compare
The delivery tube 11 is preferably shorter than the container diameter or the inside diameter of the protective cap 12.
Preferably it is provided that the spray head 5—especially with the delivery tube 1 connected and/or not connected to the nozzle 6—does not project laterally beyond the periphery of the container 3 or container edge 9 and/or fits under the protective cap 12. In particular, the protective cap 12 can therefore always be placed on the container independently of the pivoted position of the delivery tube 11.
Preferably, the delivery tube 11 can be folded up away from the nozzle 6. Especially preferably, the delivery tube 11 can be pivoted or folded around an axis 18 which runs in front of and/or above the nozzle 6.
Especially preferably, the spray head 5 has a preferably groove-shaped top recess 13 for holding the delivery tube 11. The recess 13 is formed especially in the actuating surface 10 of the spray head 5. Especially preferably, the recess 13 and the delivery tube 11 are matched to one another and/or the spray head 5 is made such that the delivery tube 11 can be held in the recess 13, without its projecting above the actuating surface 10. However, this does not preclude the delivery tube 11, in the storage position held in the recess 13, from projecting laterally beyond the spray head 5 or the actuating surface 10, as is indicated in
Preferably, the recess 13 and the delivery tube 11 are matched to one another such that the delivery tube 11, in the swung-up storage state in the recess 13 is held by clamping or catching in the recess 13.
The delivery tube 11 preferably cannot be detached from the spray head 5. However, the delivery tube 11, in a simplified version, can also be detachable from the spray head 5. Preferably, the delivery tube 11, in this case, can then be held by the recess 13, especially can be clamped into it. Alternatively, the recess 13 can also be made, for example, as a hole into which the delivery tube 11 can be inserted. In this case, the hole can run, for example, also transversely to the main delivery direction and/or axially or in the actuation direction of the spray head 5.
The delivery tube 11 is preferably straight and/or rigid. The length of the delivery tube 11 corresponds preferably is equal to the diameter of the spray head 5, but can exceed it by as much as 30%.
Preferably, the delivery tube 11 has a connecting section 14 and can be connected to a seal 15 of the nozzle 6, especially can be inserted into it. In the illustrated embodiment, the seal 15 is especially made annular or hollow-cylindrical and is located especially in front of the nozzle 6, for example, is held in a corresponding recess of the spray head 5.
The delivery tube 11 is provided especially preferably with an adapter 16, especially is held by it and/or inserted into it. In the illustrated embodiment, the adapter 16 forms the connecting section 14. Preferably, the adapter 16 is supported to be able to pivot on the spray head 16.
Especially preferably, the spray head 5 has at least one, preferably two holding devices 17, which are located laterally next to and/or above the nozzle 6 for pivotably supporting the delivery tube 11 or the adapter 16.
Especially preferably, the adapter 16 has lateral bearing projections 18 which form the pivot axis of the adapter and are which are clipped into the holding devices 17 or is pivotally connected to the spray head in some other way.
Preferably, the delivery tube 11 is held or can be fixed by clamping and/or catching in the swung-out active position in front of the nozzle 6.
