Definitions

  • the present invention relates to a manually operated spray pump for liquids, comprising a trigger, a piston operated by the said trigger in opposition to a reaction spring and movable axially within a cylindrical chamber for the compression of liquid sucked from a container which can be grasped in one hand, a suction duct, one of whose ends extends inside the container to a point near its base and the other of whose ends is connected to the said cylindrical chamber, a supply duct communicating at one end with the said cylindrical chamber and at the other end with an atomizer member, first valve means interposed between the said supply duct and the said first chamber, second valve means interposed between the suction duct and the said cylindrical chamber, and a base element for mounting the pump on the said container, for supporting the said cylindrical chamber and the said supply duct.
  • Spray pumps of the aforementioned type are well known in the specific field and are used to spray the widest range of types of products, including cleaning liquids.
  • connection between the spray apparatus and the container is also inverted
  • suitable and conventional sealing members are provided in the said connection in order to prevent the outflow of the liquid, together with suitable intake devices in the liquid suction duct which enable the liquid to be collected not only when the container is in its normal vertical position, with the spray device uppermost, but also when it is inverted and the liquid accumulates at the connection between the container and the pump, leaving uncovered the aperture of the suction duct, which, as is known, is positioned near to the closed base of the container.
  • the object of the present invention is therefore to provide a spray pump structure capable of being used even in the inverted position with highly reliable sealing and rapid priming, even when the pump has remained inactive for a long period.
  • the pump according to the invention comprises a cylindrical body 1 which extends axially in the direction of the vertical axis X-X; this cylindrical body forms a cylindrical chamber 2 with an open end 3 and a base closed by the wall 4.
  • This wall is provided with an annular rim 5 which is engaged, in an axially slidable way, in an annular channel 6 carried by a body 7 which forms two cylindrical extensions 8 and 9 which are orthogonal with respect to each other.
  • the extension 8 which is perpendicular to the axis X-X, forms in its interior the supply duct 10 which terminates in a conventional atomizer member indicated as a whole by the number 11.
  • the extension 9 which extends parallel to the axis X-X and concentrically with the cylindrical body 1, forms the housing 12 for the pump and forms the base for the support and operation of the trigger 13 by which the pump is put into action.
  • the trigger 13 is movable angularly about the pivot 14.
  • the supply channel 10 is connected to the said cylindrical chamber 2 through the passages 15 and 16.
  • the base wall 4 fits closely onto the opposing surface of the body 7 and the passages 15 and 16 are therefore closed. These passages, together with the wall 4 and the body 7, form the first valve means interposed between the chamber 2 and the supply duct 10.
  • a piston 17, with an axial cavity 18, is operated by the trigger 13 for a reciprocating movement along the axis X-X, and its extension 19 which extends within the cylindrical chamber 2 is provided with axial ribs 20 disposed in the form of a cross on the inner surface.
  • the container 23 is connected by conventional fastening means and suitable sealing members to the tubular base extension 9.
  • the said piston 17 is operated, so that it moves in a reciprocating way along the axis X-X, by the trigger 13 through lever-type connecting members which are not illustrated since they are not necessary for the understanding of the present invention.
  • a tubular sleeve, of which one part 29 extends to engage slidably with the wall of the cylindrical body 1 from the outside, is provided coaxially with the extension 19 of the piston 17 and is integral with the peripheral edge of the said piston.
  • annular collar 30 which forms a seat 31 for one end of the spring 32 whose other end is engaged in the seat 33 formed by the flange 34 which is integral with the said first cylindrical body 1.
  • the mouth 35 of the container 23 is closed by a transverse wall 36 provided with a central aperture 37 through which the tubular body 21, forming the duct 18 in its inner part, passes slidably.
  • the rim of the said aperture 37 provides, by interaction with the outer surface 38 of the tubular body 21, sufficient sealing to prevent the liquid from filtering along the said surface even if the container 23 is held in the inverted position and the pump, also inverted, is in the underneath position, as illustrated in Figure 2.
  • the last of these, in particular, is made by press-moulding from conventional plastic material with thin walls.
  • the transverse wall 36 is provided with a valve device capable of balancing the internal pressure with the pressure outside the container.
  • This valve device consists of a hole 41 covered by a membrane 42 of a known material which is impermeable to liquids but permeable by gases, particularly air.
  • the spray pump is completed by a conventional cover indicated by the number 43.
  • the tubular body 21 through which the suction duct 18 passes is connected, at the end 44, to the connection 45 of a supplementary access device, indicated as a whole by 46, which enables the suction duct 18 to be supplied even with the container 23 inverted ( Figure 2) in which position the duct 22 is no longer capable of sucking the liquid.
  • This access device 46 consists of a body 47 which comprises an access channel 48 which extends parallel to a channel 49 connected to the duct 18 through the connection 45.
  • the channel 48 is provided with a conical portion 48a forming the seat for a first ball valve 50.
  • the said channel 48 is connected to the duct 18 by means of a passage 51 and has an aperture 52 facing the transverse wall 36.
  • the internal projections 53 prevent the ball 50 from falling by gravity out of the duct 48 when the container 23 is inverted.
  • An aperture 54 provided on the wall of the duct 48, permits the entry of the liquid when this is sucked up with the container 23 in the inverted position and the ball 50 bears, by gravity, on the projections 53.
  • the body 47 also comprises a second ball valve 55 positioned in the passage 51. This ball 55 closes and opens the orifice 56 of the suction duct 22 following an axial displacement between the said orifice 56 and an opposing projection 57 formed in the wall 58 which separates the channels 48 and 49 of the body 47.
  • the vacuum created inside the container 23 following the repeated suction of the liquid is compensated by the external air which automatically passes through the gas-permeable membrane 42 disposed on the hole 41 of the transverse wall 36.
  • the liquid 24, pressurized in the chamber 2 also flows into the passages 15 and 16 formed in the thickness of the base wall 4, and passes beyond the said base wall.
  • the pressurized liquid which has passed through the wall 4 causes an axial thrust which overcomes that of the spring 35, moving the body 1 axially in the opposite direction to that of the piston 17.
