  • the invention relates to a spray head for a particular pressurized dispensing container, in particular for a spray or aerosol can, wherein the spray head has a housing and a push button, wherein the connection of an outflow channel with the dispensing container outlet receptacle can be produced by pressing the push button.
  • spray head is understood to mean any dispensing head with which a product can be dispensed from a dispensing container. This does not necessarily involve spraying or spraying. The product may also simply flow out of the top of the dispenser.
  • dispensing containers are bodies with a central axis arranged outlet on which the required valve is placed.
  • Pressurized dispensing containers such as spray or aerosol cans, are mostly cylindrical bodies with a central axis outlet on which the required valve is mounted. By pressing on a corresponding push button, such a valve is opened, and the product can flow out or spray out.
  • a longer operation for example when spraying large areas over a period of 20 seconds to the minute range towards, is a burden for the user, since he must hold the triggering push button usually with his forefinger depressed.
  • pressurized dispensing containers here is a not negligible force to spend.
  • the invention is based on the object to provide a spray head, which allows a release of a product from a dispensing container over a longer continuous period in a simpler manner.
  • the user of a container for example a spray can, which uses such a spray head, can advantageously determine the first opening guarantee on webs in the region of the unlocked catch.
  • Fig. 1 shows a perspective view of a spray head 10 according to a first embodiment of the invention.
  • the spray head 10 is seated on a dispensing container 11, which is only hinted at very schematically here.

  • a push button 20 is provided, wherein this in the Fig. 1 opposite the outlet 13 is clearly visible by a provided in the body 12 locking recess 14.
  • a central-axis (not shown) can outlet is generally arranged, on which the spray head 10 is placed.
  • the spray head 10 engages with its dispensing container outlet receptacle 21, which is shown in further figures, in a sealing manner in this can outlet.
  • the spray can 1 can also be another pressurized dispensing container.
  • spray head also means any dispensing device with which in particular fluids can be dispensed. These may also be gases, suspensions, aerosols, smoke, vapors, liquids, etc.
  • the push button 20 may be integrally formed with the outlet 13 and then moves when depressing the push button 20 of the outlet 13 in a housing 12 corresponding slot provided in the direction of the dispensing container 11.
  • the outlet 13 may also be integrated into the housing 12 and through a push-button-mediated bending movement actuates the valve of the can outlet.
  • the spray head 10 is preferably made of plastic.
  • the housing 12 has on the locking recess on a horizontal surface 15 which merges centrally and in alignment with the outlet 13 in an L-shaped locking tab 31.

  • the arms slide past the locking recess 24 on the locking tab 31 and the latching hook 41 can engage in the complementary hook on the locking tab 31, which does not happen without additional pivoting movement.
  • the Fig. 3 shows the corresponding locked function of the spray head.
  • the user must have actively acted on the rear portion 23, for example in the direction of the arrow 17, the lock.
  • the user can in principle release the push button 20, since the locking ensures a more extensive outlet of the product from the dispensing container. If the user wishes to stop dispensing or regain control of the dispensing, further pressure is applied to the rear area in the direction of the trigger 18, since the back of the release hook 51 then abuts the complimentary inclined surface of the dispenser Hook of the locking tab 31 moves so that the latching hook 41 is released.
  • This embodiment shows in principle a locking device according to the invention.
  • the Fig. 4 shows in a perspective view of a spray head 10 with a locking device according to a second embodiment.
  • the spray head 10 is again an internally hollow, slightly truncated cone-shaped body with a housing 12 in which a push button 20 is arranged.
  • the push button 20 is merely indicated here, a pressure plate 22 is not shown for clarity.
  • the correspondingly configured in its dimensions with respect to the hollow housing 12 push button 20 is also a hollow truncated cone in its outer shape, in which on the opposite side, not shown here, a latching hook 42 is arranged.
  • the latching hook 42 projects into the locking recess 14 above its horizontal surface 15.
  • the back of the latching hook 42 is parallel, the upper surface obliquely rising opposite the rear wall of the push button 20 designed.
  • a central recess 25 is provided in the body 12, which allows the resilient receiving a locking tab 32.
  • This is preferably integrally molded on the body 12 via a film hinge.
  • This tab is in the representation of Fig. 4 , For example, in the manufacturing state, and is then pivoted by 90 °, so that the region of the tab 32 is fitted into the recess 35 and is snapped by the lateral locking lugs 26.
  • a locking hook 62 is provided, which comes to rest on actuation of the push button 20 above the latching hook 42 and thus automatically locks the push button 20. If the valve of the dispensing container already releases the outflow of material before this locking of the elements 42 and 62 happens, the spray head 10 according to the second embodiment can also be operated in blocks and without locking. To release the lock, the user presses on the enlarged designed head of the locking hook 62, so that it can release the latching hook 42.
  • the Fig. 5 shows a cross-sectional view of a derived second embodiment.
