Definitions

  • the present invention relates to a push-button device for delivering a pumped spray of liquid product from a container.
  • the invention relates to a device of the said type in which the push-button is provided with a nozzle in its lateral surface for delivering the product and is guided by means of a prismatic coupling for sliding movement in a guide sleeve fixed to the top of the container.
  • This solution prevents the push-button from moving angularly in the guide sleeve and changing the direction of the jet of product delivered by the device.
  • the prismatic coupling is achieved by giving the push-button a regular-polygonal shape which, particularly in the case of push-buttons which are short in relation to their width, encourages the push-button to jam during its axial sliding movement, particularly when the push-button and the guide sleeve are made of soft materials such as plastics.
  • the present invention provides a push-button device of the type specified above, whose characteristic lies in the fact that the coupling surfaces between the push-button and the guide sleeve are constituted exclusively by axial ribs of the push-button and corresponding grooves within the sleeve.
  • the push-button is prevented from jamming even if the apparent ratio of its length to its width is very small since it is the ratio of the length to the width of the axial ribs of the push-button which affects the jamming.
  • a container is indicated 1 and, in the embodiment illustrated, is constituted by a canister, but could alternatively be another type of container, such as a scent bottle with a shape which is not radially symmetrical, for example a rectangular shape in plan.
  • a guide sleeve 2 is fixed in known manner to the top of the container 1 and a manually-operable, axially-slidable push-button 3 is slidable axially therein.
  • the operation of the push-button 3 causes the liquid in the container to be sprayed through a nozzle 4 in the lateral surface of the push-button due to the pumping effect.
  • the push-button 3 is guided in the sleeve 2 by means of a prismatic coupling the surfaces of which are constituted exclusively by axial ribs 5 of the push-button and by corresponding grooves 6 within the sleeve 2.
  • the portions of the lateral surface of the push-button 3 which are between the ribs are spaced from the facing surfaces of the sleeve 2 and are suitably decorated with fine grooves.
  • the top of the push-button 3 has an inclined surface 7 and a limited flat surface 8; the surface 7 has a depression 7a which constitutes a seat for the thumb of the hand operating the device.
  • the coupling of the ribs 5 with the grooves 6 prevents any jamming during the axial movement of the push-button even when there is a very small apparent ratio between its length and its width.
