Definitions

  • the invention relates to an actuator cap of those which have a cannula for the aerosol outlet and a double dome, with an inner and an outer drum, the outer perimeter of defence and protection and, the interior, a reinforcement and support of the elements that allow the handling of the aerosol stem.
  • the inner drum has:
  • the technical field to which it belongs is that of actuating caps for aerosols, especially for air fresheners and insecticides.
  • the outer drum has perimeter walls and an open lower base and a closed upper base, at least partially, which it usually shares with the inner drum.
  • the inner drum usually supports the push-button, which is a moving element, usually pivoting, that can plunge when vertical pressure is applied, that element being the one that presses the stem and releases the spray.
  • the push-button which is a moving element, usually pivoting, that can plunge when vertical pressure is applied, that element being the one that presses the stem and releases the spray.
  • This moving element which is usually accessed from the upper base of the outer dome, typically has its support in the inner drum that sometimes not only serves as a support for the pivoting element but rests on the aerosol itself giving it greater resistance.
  • Spanish patent ES2039744 European patent validation 89108258.8 relates to an actuator cap that allows a slightly inclined spray with respect to the vertical.
  • this patent there are also two concentric domes and a thick-walled outlet cannula. This outlet cannula is in permanent contact with the stem.
  • Patent WO93/12992 relates to a cap without cannula, wherein the descent of the pushbutton causes the inclination of a specific stem until it faces an outlet orifice that presses on it generating the output of the product.
  • the embodiment of this patent requires a stem with bending capacity.
  • Patent WO2004/020313 relates to a cap having an outer and an inner dome with a depressible area and with a cannula suitable for housing a stem.
  • the cannula has thick partitions to assume the flaring of its lower end.
  • None of the previous patents includes an actuator cap wherein the use of a conventional stem is allowed that is not in permanent contact with the outlet cannula, with the cannula having a flared end and, at the same time, walls of reduced thickness, all of which are linked to a lightened inner dome but without loss in terms of robustness or performance.
  • the proposed actuator cap in addition to a reduction in the thickness of its perimeter walls, has a double-drum dome comprising two concentric drums, wherein the inner drum comprises perimeter skirts that have strategic side cavities and a cannula with a specific geometry with a flared lower mouth whose diameter is greater than the outer diameter of the rest of the cannula since the thickness of the walls thereof has been reduced.
  • the skirt of the inner drum has strategic cavities on its sides that do not affect either the point on which the button pivots or the stop that prevents the button from sinking more than expected. These cavities narrow as they approach the upper base of the inner drum, resulting in a widening of the physical skirt portion. In this way, the area closest to the upper base of that inner drum has a complete skirt that we will call the upper ring that provides stability to the button.
  • the cannula located inside the inner drum, has a reduction in the thickness of its walls, keeping the flare of its lower mouth to such an extent that the diameter of its lower mouth is greater than the outer diameter of its main body.
  • the flared area In order to avoid problems in the demoulding, due to the undercut that the flared area would entail, it has a geometry that allows its folding at the time of the demoulding, which is carried out hot. Once demoulded, the flared area, when cooled, regains its shape.
  • the invention relates to an actuator cap with inner drum wherein said inner drum has a significant reduction in plastic without impairing its performance. To do this, part of the perimeter skirt of the drum has been strategically removed and the thickness of the walls of the outlet cannula has been reduced, but with a geometry that allows the lower base of the cannula to be flared and facilitates demoulding.
  • the inner drum (3) of the actuator cap comprises:
  • the side cavities (11) help to lighten the inner drum and reduce plastic consumption. These cavities are strategically arranged and take a specific form so that the actuator cap maintains its performance both in functionality and robustness.
  • the cavities gradually narrow as they approach the upper base of the inner drum in such a way that in the part adjacent to said upper base a ring (12) is generated that gives stability to said upper base.
  • the walls of the drum are reduced in practice to two extensions, one that extends to the pivot point (4) of the push-button (5) and another that extends as a stop (6) of the path of the push-button.
  • the outlet cannula (7) which leads the product from the outlet of the stem to the outside of the cap, has a flared area (8) that ends in a lower mouth suitable to guide the pipe (14) and the body of the cannula towards the stem in each press.
  • the stem and pipe can be at a certain distance from one other and only come into contact at the time of spraying once the cannula, by pushing the button, advances and bridges the distance that separates the stem and the pipe. This distance, in addition to facilitating the assembly operations of the actuator cap and the aerosol in the assembly chain, prevents any pressure on the button from directly moving the stem and generating a spray.
  • the flared area has an open geometry towards the outside to generate the flaring but with a wall thickness in the flaring that is gradually reduced towards the end, which allows its folding at the time of the demoulding, which is carried out hot, so that when it cools, it resumes its shape.
