Definitions

  • the present invention relates to a dispenser cap for a liquid container which can deliver a fixed dose of liquid in a reliable and simple manner.
  • Certain liquid compositions are intended to be dispensed in specified quantities.
  • One simple solution to this problem is to provide a separate measuring container with the liquid product.
  • this solution is simple, it suffers from the drawback that the measuring container may become lost or separated from the liquid container.
  • dispensing caps for liquid containers have been developed which are designed to deliver fixed quantities of liquid. As the dispensing cap is integral to the container, it cannot become detached and lost. However, most of these devices are complex to manufacture.
  • US 6,341,718 Schothuizen et al. discloses a squeeze bottle for dispensing a liquid in a metered manner, wherein the metering chamber includes several moving parts. Thus it would be desirable to provide a dispensing cap with a more limited number of moving parts that is relatively simple to manufacture and/or is easy to assemble.
  • a dispenser cap with such an arrangement allows the delivery of a metered dose of a liquid and additionally or alternatively is easy to use and/or has a low manufacture cost.
  • the invention relates to a container for holding a liquid comprising a dispenser cap according to the first aspect of the invention.
  • a dispenser cap according to the present invention has a simple mechanism and is likely to be relatively simple and/or cheap to manufacture.
  • a dispenser cap according to the present invention is relatively robust due to its simple configuration. Buoyancy depends on volume, and as such the buoyancy of the piston will be reduced if it is compressed, therefore it is desirable that the piston is of a relatively rigid material.
  • the piston comprises a rigid outer structure enclosing a cavity.
  • the cavity preferably comprises a gas, more preferably air. Nevertheless, it is also envisaged that the cavity may contain a solid foam material.
  • Figure 1 shows an axial cross-sectional view of a dispenser cap according to an embodiment of the invention.
  • Figures 2a to 2d are a series of axial cross-sectional views showing the operation of a dispenser cap according to an embodiment of the invention wherein the dispenser cap is attached to a liquid container.
  • a preferred embodiment of a dispenser cap according to the invention is shown in Figure 1.
  • the dispenser cap 1 is shown in its rest position.
  • Such a dispenser cap comprises a small number of moving components and is thus relatively robust.
  • the dispenser cap 1 comprises a means for attachment 2 to a container, a channel and a liquid outlet 3.
  • the dispenser cap 1 may be attached to the container by any suitable means, for example by friction fit, gluing, snap-fitting or screwing.
  • the means for attachment 2 to the container includes means such as a screw thread or snap ribs, however it is also envisaged that the dispenser cap need not require discrete fasteners.
  • the dispenser cap is typically attached to the liquid container such that the liquid can be expelled from the container via the dispenser cap.
  • the dispenser cap is attached to the liquid container such that the channel projects into the container opening, e.g. the channel may project into the neck of the container. It should be noted that radial clearance between the exterior of the channel and the interior of the container opening is maintained so as not to impede the flow of liquid into the dispenser cap.
  • a moveable piston 6 is contained within the bore of the channel. Said piston is movable along the longitudinal axis of the channel.
  • the piston 6 is biased to a first position against the stop 4 by a buoyant force whereby a dosing chamber 7 is defined by the piston 6, the channel walls 5 and the liquid outlet 3.
  • the piston 6 is fitted so as to be able, in response to pressure, to move from a first position in which the dosing chamber 7 has a maximum volume to a second position in which the dosing chamber 7 has a minimum volume.
  • the piston preferably fits substantially into the bore of the channel (i.e. occupying nearly all the cross-section without being a tight fit), so as to be freely slidable within it.
  • a first surface 8 of the piston 6 is in communication with the interior of the liquid container and a second surface 9, which is opposite the first surface 8, is in communication with the dosing chamber 7.
  • the channel walls 5 comprise one or more inlet(s) 10.
  • the channel walls 5 contain from 1 to 8 inlets, more preferably from 2 to 6 inlets.
  • the inlet(s) 10 are arranged such that the dosing chamber is in fluid connection with the liquid container when the piston 6 is in its first position (i.e. when the first surface 8 of the piston 6 is butting against the stop 4).
  • the positioning of the inlet(s) 10 means that when the piston 6 is in its second position (i.e. when the second surface 9 of the piston 6 is adjacent to the liquid outlet 3) the dosing chamber is isolated from the liquid container by virtue of the piston 6 closing off the inlet(s) 10.
  • the dosing chamber 7 is in selective communication with the liquid container via the inlet(s) 10.
  • said inlets are preferably arranged around the circumference of the channel at a uniform distance from the liquid outlet.
  • the inlets may be arranged in tiers.
  • the precise number and arrangement of the inlet(s) may vary, as may the size of the inlet(s).
  • a higher number of inlets and/or a larger size of inlets may be necessary in order to avoid the inlets becoming clogged with product and impeding the function of the dispenser cap.
  • each of the inlet(s) should nevertheless be smaller in size than the bore of the channel.
  • each of the inlet(s) will be smaller in size than the liquid outlet and, in those preferred embodiments wherein the second end of the channel is an open end, each of the outlet(s) will also be smaller in size than the second open end of the channel.
  • the liquid outlet 3 is preferably centred on the longitudinal axis of the channel.
  • the liquid outlet 3 houses a valve 11.
  • the liquid outlet valve 11 is typically included in order to help prevent unwanted leakage of liquid when the dispenser cap 1 is not in use.
  • the liquid outlet valve 11 is preferably a non-return valve.
  • the liquid outlet valve 11 comprises an elastically deformable membrane having at least one slit (i.e. a so-called slit valve). The degree of closure of the slit may depend to a large extent on the viscosity of the liquid product.
  • the liquid outlet valve 11 is resiliently biased to its closed condition.
  • a cap may be provided to reversibly cover the liquid outlet.
  • This cap may desirably include a plug closure for the liquid outlet.
  • the cap may be integrally hinged to the dispenser cap.
  • the dispenser cap is attached to a liquid container 12.
  • the type of container to which the dispenser cap may be attached is limited only in that said container is suitable for holding a liquid and should comprise an opening through which the liquid can be expelled from the container. Indeed, it is envisaged that the dispenser cap can be manufactured to fit containers having openings of standard sizes. However, it is also possible to form the dosing chamber 7 of the dispenser cap integrally with the container, for example as part of the neck of a bottle, if this is desired.
  • the container is a hand-held container.
  • the dispenser cap operates in response to a pressure increase to dispense a metered dose of the liquid product.
  • Figures 2a to 2d show an embodiment of the dispenser cap in use according to the invention.
  • Figure 2a shows the dispenser cap in its rest position.
  • the dispenser cap is attached to a liquid container 12.
  • the piston 6 is in its first position such that the dosing chamber 7 has a maximum volume.
  • an increase in pressure in the container forces liquid between the second end of the channel and the first surface of the piston.
  • the increase in pressure in the container may be achieved by any suitable means.
  • the container is squeezable (e.g. by hand pressure) and hence the increase in pressure within the container may be induced by squeezing the container.
  • the container preferably has deformable resilient sides, i.e. sides which deform when a force is applied thereto (e.g. by squeezing) and return to their original configuration when released.
  • the container is a hand-held container.
  • the liquid outlet 3 houses a valve 11.
  • the valve 11 may by glued, snap-fitted, welded, or otherwise fastened around the liquid outlet 3.
  • the liquid outlet valve 11 may comprise an elastically deformable membrane.
  • the membrane may include at least one slit, closed in the absence of pressure inside the dosing chamber 7 and capable of opening in response to an increase in pressure therein.
  • the membrane may be capable of occupying a concave profile with respect to the dosing chamber 7 (as shown, for example, in Figure 2b) in response to pressure exerted by the liquid product being expelled from the liquid outlet 3.
  • the piston 6 continues to move in the direction of arrow A until the piston 6 reaches its second position as shown in Figure 2c. In this second position, the piston 6 seals the liquid outlet 3 such that there is substantially no leakage of the liquid product from the dispenser cap.
  • the dispenser cap optionally comprises a seat 13 against which the piston abuts in order to seal the liquid outlet.
  • a seat 13 where present, is preferably positioned adjacent to the liquid outlet (3) and optimally extends circumferentially around the liquid outlet (3) in a continuous manner.
  • the flow of the liquid through the liquid outlet 3 is preferably cut off suddenly and completely with little or no subsequent dripping.
  • the liquid outlet 3 houses a valve 11, wherein said valve preferably allows the flow of liquid to be interrupted instantaneously.
  • the piston 6 restricts the flow of liquid from the container into the dosing chamber 7 when it is in its second position by closing off the inlet(s) 10. It will be noted that when the piston 6 is in this second position the dosing chamber 7 has a minimum volume. As shown in Figure 2d, once the force exerted on the container walls is released (e.g. by the user ceasing to squeeze the container), the resilient nature of the container walls means that they return to their original configuration, which in turn causes the container to expand to its original volume. Liquid is no longer forced between the second end of the channel and the piston and consequently force F is no longer exerted on the piston. The buoyancy of the piston 6 now urges it back towards its first position in the direction of arrow B.
  • the container is preferably fitted with an air admittance valve 14 which allows air to enter the container to replace the volume of product dispensed.
  • the air admittance valve is a non-return valve which allows substantially no flow of liquid out of the liquid container, and in a particularly preferred embodiment it is a so-called duckbill valve.
  • the expansion of the liquid container to its original volume causes the air admittance valve to open and admit air as shown by arrow D.
  • the reduced pressure in the dosing chamber may cause the membrane to return to a convex profile with respect to the dosing chamber 7 (as shown, for example, in Figure 2d). During this return of the membrane towards the inside of the dosing chamber 7, it is preferably that there is substantially no backflow of air into the liquid container. In certain embodiments, however, there is a possibility that a small intake of air towards the container may occur.
  • the moveable piston 6 continues to move in the direction of arrow B until it has returned to its first position, hence the components assume the same position shown in Figure 2a and the next dose may be dispensed.
  • the moveable piston 6 has a fixed stroke.
  • the channel walls 5 and/or the moveable piston 6 are of a relatively rigid material so as to ensure that any pressure increase does not deform these components. In certain embodiment it may be desirable to limit the number of inlet(s) 10 so as not to impact the structural integrity of the channel walls 5.
