Definitions

  • the present invention relates generally to nozzles for manually-operated pump dispensers such as trigger sprayers, and more particularly to such nozzles having child-resistant features.
  • the nozzle is child-resistant in that two distinct motions in different directions are required in order to disengage the closure member so that the fluid may be dispensed.
  • a fluid dispenser of the type involved in the present invention is a relatively low-cost, hand-held trigger sprayer which may be manually operated by pulling a trigger to pump liquid from a container attached to the sprayer through a nozzle orifice at the front of the sprayer.
  • Fluid dispensers of this type have a variety of features which have become well-known in the industry.
  • the dispenser may have a dedicated spray nozzle which produces a fixed spray pattern such as a narrow stream or a fine mist.
  • the fluid dispenser may be of the type which has a variable spray pattern.
  • Still other fluid dispensers permit a foaming liquid to be dispensed as either a foam or a liquid spray.
  • the child-resistant nozzle of the present invention is equally well-suited for use in each of these types of fluid dispensers, as well as, virtually any other type of fluid dispenser.
  • the fluids dispensed are frequently chemicals which are harmful or fatal if swallowed. Further, the chemicals are sometimes caustic and thus are harmful to individuals if they come in contact with the skin for any appreciable length of time. These harmful effects are frequently more pronounced in children because of their relatively small size and sensitive tissues. In addition, because children may not be able to read or understand textual or graphical warnings printed on the containers, they may not be able to appreciate the danger associated with the chemicals and thus have an increased risk of coming in contact with and being injured by these chemicals ' .
  • children may be more susceptible to being injured by chemicals dispensed from trigger sprayers, they are easier to protect from the harmful effects of the chemicals by physically locking the containers. Children may be prevented from accessing chemicals contained in a trigger sprayer by incorporating a locking closure on the trigger sprayer nozzle. Experience has shown that simply by requiring that two independent movements in different directions be performed in order to open a container, a significant number of children may be prevented from completing the tasks and others may be inhibited from completing the tasks for a sufficient length of time so that an adult may be alerted to the potentially harmful acts of the child and take appropriate action.
  • the door which shows a fluid dispenser having a door with an aperture through it.
  • the door slides relative to the nozzle orifice of the dispenser to alternately align and misalign the aperture with the nozzle orifice to alternatively permit and prevent dispensing liquid, respectfully.
  • the door also includes a deflectable latch which engages against the housing when the door is in the closed position to prevent the door from being moved to the open position. To open the door, the user must deflect the latch forward and simultaneously slide the door upward to the open position to permit liquid to be dispensed from the fluid dispenser.
  • the child- resistant feature of the Wesner reference may be easily opened with one hand by pulling the latch forward and then upward.
  • each of the previously described fluid dispensers includes a child-resistant locking feature which requires two motions in order to dispense fluid through the fluid dispenser.
  • the motion is simple and the locking feature may be opened unintentionally or without much effort using just one hand.
  • the present invention is directed to a novel child-resistant fluid dispenser comprising a dispenser body, a nozzle assembly or nozzle, a nozzle closure member and a pair of levers.
  • the dispenser body has a nozzle receiving end and a fluid discharge conduit configured for discharging fluid through the nozzle receiving end.
  • the nozzle has a fluid passage extending therethrough.
  • the fluid passage has a rearward end in fluid communication with the fluid discharge conduit of the dispenser body and a forward end for discharge of fluid from the fluid passage.
  • the nozzle closure member and the nozzle are configured so that when the nozzle closure member is in its closed position, the nozzle closure member blocks discharge of fluid from the nozzle.
  • the nozzle closure member and the nozzle are further configured so that when the nozzle closure member is in its open position, the nozzle closure member permits discharge of fluid from the nozzle.

  • the locking portion of each lever is configured for engaging the nozzle closure member.
  • Each of the locking portions of the levers are moveable between an engaging position in which the locking portion engages the nozzle closure member and a nonengaging position in which the locking portion is spaced from the nozzle closure member.
  • the levers and the nozzle closure member are configured to lock against movement of the nozzle closure member from its closed position when the locking portions are in their engaging positions.
  • the levers and the nozzle closure member are further configured to permit movement of the nozzle closure member between its open and closed positions when the locking portions are in their nonengaging positions.

  • the child resistant closure lock of the present invention is disclosed in two embodiments, the first of which may be employed on trigger sprayers of the type having a pivoting closure such as that disclosed in the U.S. patent of Foster et al . No. 5,385,302 and the U.S. patent of Nelson No. 5,373,991, both of which are incorporated herein by reference, as well as other similar trigger sprayers employing a pivoting closure, and the second of which may be employed on a trigger sprayer having a rotating closure such as that disclosed in the U.S. patent of Foster et al . No. 5,234,166, incorporated herein by reference, as well as other similar types of trigger sprayers having rotating closures.
  • both embodiments of the closure locks may be employed on other types of liquid dispensers such as lotion pumps and vertically reciprocated sprayer dispensers.
  • liquid dispensers such as lotion pumps and vertically reciprocated sprayer dispensers.
  • the embodiments of the closure locks will be described with reference to trigger sprayers, but it is not intended that their use be limited to trigger sprayers and it should be understood that the closure locks of the invention may be employed on various different types of liquid dispensers.
  • FIG. 1 shows the general representation of the forward portion of a prior art trigger sprayer.
  • the trigger sprayer is comprised of a housing 10 containing a liquid discharge passage 12.
  • the discharge passage 12 has an outlet opening 14 at its downstream end, and usually is provided with a check valve (not shown) at its upstream end (not shown) .
  • the typical trigger sprayer housing also contains a pump chamber (not shown) in which a pump piston (not shown) having a piston rod 16 is reciprocated between charge and discharge positions relative to the pump cylinder. Reciprocation of the pump piston 16 in the piston chamber cylinder to the charge or extended position of the pump piston relative to the cylinder will draw liquid from a container (not shown) connected to the trigger sprayer housing through a dip tube (not shown) of the trigger sprayer into the pump chamber.
  • a trigger 20 is attached to the trigger sprayer housing 18 for pivoting movement relative thereto.
  • the trigger 20 engages against an end of the piston rod 16 and, on manual manipulation of the trigger, the trigger causes the piston rod 16 and its attached piston to move between its charge and discharge positions relative to the pump chamber cylinder and the trigger sprayer housing 10.
  • the trigger sprayer of Figure 1 has a nozzle 22 attached to the sprayer housing 10.
  • the nozzle 22 has a cylindrical liquid passage 24 that is inserted into the cylindrical interior of the sprayer housing discharge passage 12 through the outlet opening 14.
  • the nozzle has an orifice wall 26 at the downstream end of the liquid passage 24 and an orifice 28 passes through the orifice wall.
  • Liquid pumped through the sprayer housing discharge passage 12 by operation of the trigger sprayer pump travels into the nozzle liquid passage 24 through an inlet opening 30 at its upstream end and exits through the orifice 28 at the liquid passage downstream end.
  • a liquid spinner 32 is contained in the nozzle liquid passage 24 and imparts a spin to the liquid just before it passes through the nozzle orifice 28. This spin causes the liquid to be discharged from the orifice 28 in a conical spray pattern.
  • a closure 34 in the form of a door is attached to the nozzle 24 by a living hinge 36.
  • the closure has a sealing projection 38 on its interior surface 40 and an opposite exterior surface 42.
  • a handle 44 with a projecting gripping tab 46 is provided on the closure opposite the living hinge 36.
  • Opposite side walls 48 are positioned on the opposite left and right sides of the door closure 34. The opposite sides of the door closure 34 engage between the opposed side walls 48 when the closure is moved to its closed position relative to the nozzle and friction engagement with the sides of the door closure and the side walls holds the door closure in its closed position.
  • the user To open the door closure, the user merely positions a finger behind the handle 44 beneath the nozzle 22 and pulls the handle forwardly. This disengages the opposite sides of the door closure 34 from their friction engagement between the nozzle side walls
  • the closure door 34 can be pivoted further about the living hinge 36 until the gripping tab 46 is inserted into a housing opening 50 provided on the top of the trigger sprayer housing 10 which holds the gripping tab in friction engagement and thereby holds the door closure 34 in its open position.
  • FIG. 1 The above description of the trigger sprayer construction shown in Figure 1 is all known in the prior art.
  • the door closure 34 is not considered to be child resistant because only one motion is necessary to open the closure, i.e., the pulling of the handle 44 forwardly with the door in its closed position to pull the door from its closed position thus opening the door.
  • Figures 3-7 disclose the construction of a child resistant lock of the present invention that is employed on trigger sprayers of the type shown in Figure 1.
  • the nozzle 50 includes a liquid passage 52 that is substantially identical to the nozzle liquid passage 24 of the prior art nozzle.
  • the nozzle liquid passage 52 extends from an upstream end 54 of the passage to a downstream end that ends at an orifice 56 in the orifice wall 58 of the nozzle.
  • the exterior surface of the liquid passage 52 is cylindrical and is dimensioned to enable it to be press-fit through the outlet opening 14 of the sprayer housing liquid discharge passage 12, just as the prior art nozzle. This puts the liquid passage 52 in liquid communication with the sprayer housing discharge passage 12 and liquid pumped through the sprayer housing discharge passage 12 will pass through the liquid passage 52 and be discharged from the nozzle orifice 56.
  • the liquid passage 52 contains a liquid spinner when assembled to the sprayer housing 10 just as the prior art nozzle, and the liquid spinner imparts a swirl to the liquid as it passes through the spinner and just before it is discharged from the orifice 56 resulting in a conical spray pattern of the liquid.
  • the child resistant lock provided on the nozzle 50 is provided in part by the construction of the nozzle closure 60.
  • the closure 60 is a door that is connected to the top edge of the nozzle orifice wall 58 by a living hinge 62, just as in prior art nozzles of this type.
  • the door is also provided with an interior surface 64 and an opposite exterior surface 66 with a sealing projection 68 on the door interior surface.
  • the projection 68 is positioned on the door interior surface so that it will engage against the nozzle orifice 56 when the door is moved to its closed position thereby obstructing discharge of liquid from the orifice when the door is moved to its closed position.
  • the door also includes a handle 70 and a gripping tab 72 on the handle just as in prior art doors .
  • the closure door of the invention differs from that of the prior art in that it is provided with portions 74, 76 that project outwardly from the doors opposite left 78 and right 80 side edges, respectively. Each of the projecting portions has a general rectangular configuration.
  • the opposite interior 64 and exterior 66 surfaces of the door closure extend over the opposite sides of the left and right projecting portions 74, 76.
  • the nozzle side walls 82, 84 are similar to those of the prior art nozzle except that there are notches 86, 88 formed through intermediate portions of the side walls. As best seen in Figures 4 and 7, the notches 86, 88 are sized sufficiently large to allow the two projecting portions 74, 76 of the door to pass into the notches when the door is moved to its closed position. Above and below the notch 86 on the left side of the nozzle as viewed in Figures 3 and 4 are a pair or resilient braces 90. A second pair of resilient braces 92 are positioned above and below the notch 88 on " the right side of the nozzle as viewed in Figures 3 and 4.

  • the arms are molded integrally as a single unit with their braces of the same type of plastic employed to form the nozzle, thus giving the braces 90, 92 of each of the arms a resilience.
  • the left side arm 94 has a handle 98 that projects rearwardly from the left side braces 90 in a cantilever manner.
  • the pair of left side braces 90 position the handle 98 spaced outwardly from the left side of the nozzle and spaced outwardly from the left side of the trigger sprayer housing when the nozzle is assembled to the housing.

  • the left side braces 90 and right side braces 92 hold their respective arms 94, 96 in positions spaced laterally from the opposite left and right sides of the nozzle 50. As stated earlier, when the nozzle is assembled to the liquid discharge passage 12 of a sprayer housing, the braces also space the arms a lateral distance from the opposite left and right sides of the sprayer housing.
  • the resilience of the braces 90, 92 allow the handles 98, 104 of the two arms to be manually moved toward each other by the thumb and index finger of a user's hand resulting in the arms moving in a pivoting movement about the braces 90, 92 causing the clasps 100, 106 at the opposite ends of the arms to move laterally away from each other and away from the nozzle orifice 56.
  • the resilience of the braces 90, 92 moves the clasps 100, 106 back toward each other to their at rest positions relative to each other shown in Figures 5 and 6.
  • the user positions the arm handles 98, 104 between the thumb and forefinger of one hand and pinches the handles toward each other. This results in the clasps 100, 106 of the arms moving away from each other and away from their positions over the exterior surface of the door projecting portions 74, 76. With the clasps cleared from in front of the door exterior surface, the user then takes their other hand and pulls the door forwardly from the handle 70 moving the door from its closed position to its open position shown in Figure 3.

  • the cap On rotation of the nozzle cap 110 relative to the sprayer housing 112, the cap moves axially to the left as viewed in Figure 2 and the hub 126 is gradually withdrawn from the swirl chamber, opening the pathway of liquid through the tangential groove 128, the swirl chamber and the orifice 122.
  • rotation of the nozzle cap 110 will cause the closure or projecting hub 126 to be moved through the open and closed positions. Additionally, some trigger sprayers of this type will vary the spray pattern of liquid discharged from the orifice 122 from a conical spray pattern to a stream spray pattern as the cap is continued to be rotated relative to the sprayer housing and moves further to the left as viewed in Figure 2.
