Definitions

  • the present invention is concerned with a cap for a pressurised fluid container that allows the contents of the container to be dispensed without the cap having to be removed.
  • the invention is of particular use in the field of home and personal care when it may be used as part of a hand held aerosol dispenser.
  • US 6,398,082 discloses an actuating mechanism for a hand held canister in which a slider is moveable by finger pressure from a valve-disengaged position into a valve-engageable position and a concealed spring returns the slider to a valve-disengaged position when finger pressure is removed.
  • JP 8,011,956 discloses a cap for an aerosol container having a protrusion set up beneath an operating part or a finger board to depress a push button of the container.
  • EP 402,636 discloses an actuator for a spray pump activated by means of leverage.
  • US 3,739,941 discloses an actuator for an aerosol dispenser having a lever integrally formed in a spray through cap.
  • US 3,409,186 discloses a cap for an aerosol container comprising two lateral push-buttons having surfaces which engage co-operating surfaces on a valve-actuating member.
  • US 2007/023457 discloses an aerosol valve trigger actuator comprising a trigger member extending into a shroud and a fluid conduit within the shroud, the trigger member and fluid conduit interacting by means of a camming surface on one and a cam follower on the other to lower said fluid conduit and dispense product when the trigger is pulled towards the shroud.
  • US 4,157,774 discloses a reversible trigger actuated dispensing pump employing a reciprocal plunger having a passage for communication with a pump at one end and a nozzle at the other end.
  • the trigger includes a body portion with structure to cooperate with the plunger to permit the trigger to be releasably and pivotally mounted on the plunger.
  • US 4,264,038 discloses a manually operative atomizer in which a liquid is sucked and pressurized by an atomizer means and is then atomized through a nozzle port.
  • An atomizer head is connected to a communication pipe which acts as a piston, biased in the direction reverse to the pressurizing direction, by means of a spring.
  • the atomizer head is provided with a guiding member adapted to be pressed and moved by an inclined surface of the operation member, so that the atomizer head and the piston or the jetting pipe are moved in the pressurizing direction.
  • US 2,558,272 discloses a conventional aerosol container with an actuator button centrally located on its top surface, the top surface also having a fulcrum member located to one side of the actuator button and a level designed to detachably fit into the fulcrum member and ease depression of the actuator button.
  • US 3,189,232 discloses a spray through cap for pressurized fluid containers having a trigger assembly comprising (a) a valve stem, a chassis which includes a plinth supporting a spray channel, a cap with an outer shell with an outlet aperture and a side wall gap and (b) an activation paddle hinged on a lower edge including a member with a strut projecting inwards and pressing upon a projection of the plinth to cause the spray channel to depress.
  • US 3,189,232 does not disclose a projection from the plinth extending in a direction orthogonal to the inward projecting strut of the activation paddle. This feature of the present invention enhances the efficiency with which lateral pressure upon the activation paddle is translated into downward pressure upon the spray channel.
  • a spray through cap according to the first aspect of the invention and an associated pressurised fluid container.
  • a spray through cap according to the first aspect of the invention for dispensing a consumer product from a pressurised fluid container in the form of a spray.
  • the present invention allows lateral pressure upon the activation paddle to be efficiently translated into downward pressure upon the spray channel. Since the spray channel typically sits on top of a valve stem of an associated pressurised fluid container, downward pressure on the spray channel causes the opening of the valve and the release of the pressurised contents of the container through the outlet aperture via the spray channel.
  • the invention may be used in the dispensing of a range of consumer products. It is particularly useful for use as part of a hand held dispenser for home or personal care products, for example cosmetic compositions such as deodorants.
  • orientation terms such as “upper”, “lower” and “vertical” should be understood to be referring to the cap in its “in use” position sat on top of an upright pressurised fluid container, as illustrated in Figure 1 for example.
  • lateral should be understood to refer to the plane approximately orthogonal to the principle axis of the cap, said axis being the vertical axis when the cap is oriented as described in the previous paragraph.
  • the chassis comprises a plinth that supports the spray channel, an activation paddle, and, preferably, a means of attachment to an associated pressurised liquid container.
  • the chassis fits on to a valve cup of an associated pressurised liquid container, by means of a snap fit, for example.
  • the activation paddle is moulded independently of the other parts of the chassis and may be attached to the remainder of the chassis via cooperating hinge elements.
  • the chassis comprises means for restricting lateral pressure upon the spray channel when lateral pressure is applied to the member of the activation paddle adjacent to the sidewall gap in the outer shell.
  • Lateral pressure upon the spray channel may be restricted by supporting the spray channel upon the plinth of the chassis in a manner that resists lateral movement.
  • the spray channel is typically firmly attached to the plinth.
  • it is important that the plinth is capable of axial movement so that the spray channel may be pressed down upon the valve stem with which it is typically associated.
  • Axial movement of the plinth without undue lateral movement may be achieved by having the plinth attached to the main body of the chassis by flexible support braces.
  • the flexible support braces function cooperatively to help maintain the lateral position of plinth.
  • the support braces may flex in more than one direction, for example sideways and downwards relative to the plinth. Three or preferably four support braces may be used to advantage.
  • the flexible support braces have an S-shape or a C-shape, more preferably they have a C-shape.
  • the projection from the plinth extends in a direction orthogonal to the inward projecting strut of the activation paddle.
  • projections from the plinth extend in a direction orthogonal to the inward projecting strut of the activation paddle on either side of the lower part of the spray channel.
  • the projection or projections from the plinth may have an angular cross-section or a curved cross-section.
  • the projection or projections may take the form of a half-pipe rising from the plinth.
  • the projection or projections may have an inverted V-shaped cross-section.
  • the activation paddle comprises a member adjacent to the sidewall gap in the outer shell and a strut projecting inwards from said member.
  • struts there are two such struts, one of which press down upon a projection from the plinth on a first side of the lower section of the spray channel and the second of which presses down upon a projection from the plinth on the opposite side of the lower section of the spray channel when the member of the activation paddle adjacent to the sidewall gap is pressed inwards.
  • the activation paddles attaches to the main body of the chassis by hinge elements, for example a pin and barrel arrangement.
  • the strut or struts of the activation paddle preferably has/have support brackets in the angle between them and the member adjacent to the sidewall gap in the outer shell. Such support brackets serve to strengthen the struts and aid the depression of the spray channel.
  • the lower part of the spray channel typically sits on the top of a valve stem of an associated pressurised liquid container.
  • the spray channel provides a means for passage of fluid from the container when the valve is opened by depression of the valve stem.
  • the spray channel comprises a lower vertical part associated with a valve stem as described above and may have an upper angled part leading from the top of the lower vertical part of the spray channel towards the outlet aperture in the outer shell.
  • a swirl chamber which serves to improve the quality of the spray exiting the outlet aperture via the spray channel.
  • the sidewall gap in the in the outer shell is typically at least the width of an adult's index finger, i.e., at least 2 to 3 cm.
