Definitions

  • the present invention relates to a dispenser comprising a container for holding a product to be dispensed, said container having a container body with a bottom, a top and at least one side wall interconnecting said bottom and top, said container body further including at least one outlet opening arranged in the top part of the container body, but preferably in or near said bottom, and a dispensing mechanism interconnectingly arranged on said at least one outlet opening.
  • Dispensers are generally well known in the art.
  • Prior art dispensers of the general type typically include a bottle having a neck at the top, and a dispensing mechanism, for instance a trigger sprayer, attached to the neck.
  • the trigger sprayer may be attached to the bottle in any conventional way, e.g. by a threaded connection, a bayonet connection or a snap connection.
  • part of the trigger sprayer may be integrated with the bottle.
  • Trigger sprayers are well known in the art.
  • a problem with dispensers known in the art comprising a container for holding a product to be dispensed is that those containers, when (completely) filled, are mostly uncomfortable as a result of the weight of the liquid contained therein.
  • the filled dispenser as such therefore can sometimes be heavy and not easy in its use.
  • the current invention thus relates to a dispenser as exemplified in Figure 10 comprising a container (A) for holding a product to be dispensed and a dispensing mechanism (B), said dispenser comprises
  • the trigger sprayer (H) can be attached to the neck (K) in any conventional way e.g; by a threaded connection, a bayonet connection or a snap connection. However the trigger sprayer can also be integrated with the neck (K) and form one part.
  • the combination of the elements trigger sprayer (H), neck (K) and conduct (G) can also be attached to container body (Q) at the outlet opening (F) in any conventional way e.g; by a threaded connection, a bayonet connection or a snap connection, and may alternatively be integrated as one part with the container body (Q).
  • Suitable trigger sprayers are for instance trigger sprayers with a so-called precompression system.
  • a precompression system may be placed between a pump and a discharge nozzle that are connected by a conduit debouching in a space, the system comprising a precompression valve movable between a position closing off the connection in which it abuts a seat on the mouth of the conduit and a position releasing the connection in which it is spaced from the seat, the precompression valve being biased to the closing position by spring means.
  • a precompression system is known from e.g. USP 5,730,335 or WO 00/33970.
  • Other trigger sprayers to be used on the current dispenser are those described in e.g. USP 4,706,888 and USP 6,126,090.
  • the dispenser according to the invention may thus comprise in its trigger sprayer as part of the dispensing mechanism (B) a so-called precompression system, although it is not essential for the performance of the current invention.
  • Said dispenser may be equipped with other well known dispensing mechanisms without departing from the scope of the present invention.
  • the known precompression system is used in a sprayer head for a container, for instance a bottle, containing liquid.
  • a sprayer head is formed by a body in which a manually operable piston pump is arranged. This pump is operated by a trigger that is pivotally connected to the body.
  • the suction side of the pump is connected to a tube (N) that extends into a bottle and through which liquid may be drawn out of the bottle.
  • the compression side of the pump is connected to the discharge nozzle of the sprayer head through a conduit.
  • the precompression system comprising a precompression valve that is kept shut by spring means and that is opened only when a predetermined pressure is attained within the pump.
  • the precompression valve has for its object to prevent the fluid from leaving the discharge nozzle at too low a pressure, which would result in too large drops being formed in the spray.
  • the liquid In order to achieve an optimum spraying pattern the liquid must in fact be pressed out of the discharge nozzle at a predetermined and relatively high pressure.
  • Another advantage due to the container in accordance with the invention is that the weight of said container, when filled, does not stress the wrist resulting in a much better comfort of use.
  • the forearm supports the weight without bending the wrist.
  • the weight of a classical container or bottle forces the wrist to misalign with the arm.
  • the tube (N) attached to the sprayer usually extends into the protrusion (M) in such a way that there is a minimal left-over of liquid in the bottle because of an optimal flow of liquid from the protrusion of the bottle or container to the sprayer. There is only a very little volume left at the end of the dip tube.
  • a classical or standard spray bottle has a volume left over of about the size of the bottom of the bottle.
  • the dispenser according to the present invention is safer with regard to leakage of liquid out of the container.
  • the chance for leaking of the inventive dispenser is much smaller compared to the dispensers known in the art. If the inventive dispenser falls over on its left or right side, there is 50% less chance for leaking, because the liquid hardly reaches the closing edge of the trigger sprayer because of the shape or design of the inventive dispenser but also of the presence of the air chamber designated as A in Figures 1-5. Liquid present in a classical dispenser always reaches the closure when falling on its left or right side resulting in sometimes substantial leakage of the liquid out of the dispenser.
  • a standard trigger sprayer present on a classical spray bottle cannot conveniently be used under an inclination when the bottle is directed to the soil surface, for instance for spraying herbicides or spraying household cleaners, since it will start leaking after ⁇ 5 trigger actions or when the trigger is continuously pushed in. This is because of the 'venting hole' present in the trigger spray system. It is needed to let air into the bottle to avoid creating a vacuum in the bottle.
  • the dispenser according to the current invention causes no leaks because the air bubble (A in figures 1-5) prevents the liquid from flowing through the venting hole.
  • the inventive system prevents leakage during use because of the two communicating air chambers; one air chamber at front under trigger sprayer and one air chamber at back of bottle at top of bottle volume (see Figures 1-5).
  • Figures 1-6 show how the two air chambers (A and B) move while rotating the inventive dispenser. While spraying (triggering movement) the air pressure in chamber B will drop because of liquid going out of the dispenser. Chamber A will stay at atmosphere pressure also based upon the principle of communicating vessels. When the pressure in chamber B becomes too low (under pressure), air and pressure from chamber A is automatically transported to chamber B. At the same time, while triggering, chamber A will be filled with air again by venting. Venting is the air exchange between outside and inside air and is happening while the trigger is pressed in.
  • Information relating to the product contained in the bottle and/or to the way the dispensing mechanism can be operated is usually displayed on labels that are applied to the sides of the bottle or container. Therefore, to view this information, a prospective purchaser and/or user of the dispenser must hold the bottle up so high that the information on the labels on the sides of the bottle is visible.
  • dispensers In addition, purchasers of this type of dispensers usually store them in their homes in locations where they are easily accessed when needed.
  • the dispensers are often stored in a cabinet beneath the sink of the home along with other cleaning and related products that are contained in bottles or dispensers, often bottles with trigger sprayers.
  • the user When looking for a particular product contained in a bottle or dispenser that is stored beneath a sink, the user is often required to pick up each of the bottles and dispensers stored there to view the sides of the bottles and dispensers in order to determine their contents.
  • Part of the present invention is to provide a dispenser of the type described above in which the above discussed drawbacks associated with prior art dispensers are overcome. This is achieved in such a dispenser wherein the dispensing mechanism carries at least one label displaying information. With the information displayed on the dispensing mechanism, which is arranged on top of the bottle, it is not necessary to hold the dispenser up high in order to view the information.
  • label is intended to denote any object that is suitable for displaying information.
  • the dispensing mechanism includes at least one top surface, the at least one label being arranged on the top surface.
  • the information which may include information on how to operate the dispensing mechanism, is then readily visible when the dispenser is held in the hand prior to or during its use.
  • the at least one label preferably displays the information in at least two different colors.
  • the information may relate to the product to be dispensed and/or to the use of the dispensing mechanism.
  • FIGS. 2 to 6 show the spraying positions. While spraying (triggering movement) the air pressure in chamber B will drop because of liquid going out of the bottle. Chamber A will stay at atmosphere pressure. When the pressure in chamber B becomes too low (under pressure), air and pressure from chamber A is automatically transported to chamber B and liquid flows to the dispensing mechanism. At the same time, while triggering, chamber A will be filled with air again by venting.
  • Venting is air exchange between outside and inside air and is happening while trigger is pressed in.
  • Figure 7 shows the condition when the bottle is positioned on the forearm before triggering is activated. [similar to positions in figures 2 to 5, without triggering activated] At this condition the pressure in Pa1 is equal to the pressure in Pb1 plus the hydrostatic pressure (Ph) from liquid level difference C1. Pb1 is at atmosphere pressure.
  • Ph hydrostatic pressure
  • liquid level A1 being in balance with liquid level B1, determined by the respective air chambers Pa1 and Pb1
  • Figure 8 shows the condition when the bottle is positioned on the forearm while triggering is activated. At this condition the venting hole is opened and the hydrostatic pressure forces the pressure in Pa1 to exchange with outside air until Pa2 is at atmosphere pressure. This results in liquid level A2 to rise while liquid level B2 drops. At this moment Pb2 enters into under pressure.
  • Figure 9 shows the condition when the bottle is positioned on the forearm during and after triggering is activated. At this condition the venting hole is opened and closed. The liquid level A2 drops to A3 because of liquid taken out by the dip tube. Pressure in Pb2 drops further to Pb3 and air/pressure exchange takes place when liquid level A3 is at level D3. Air and pressure from chamber Pa3 is automatically transported to chamber Pb3 and liquid flows to the dispensing mechanism.
  • Ip 1.000bar (internal pressure)
  • Up 0.995bar (external pressure)
  • ⁇ p 0.005bar (pressure difference between internal and external)
