Definitions

  • an emulsion dispenser of the prior art comprises a housing 10 in which a plunger 11 is disposed such that the top end of the plunger 11 extends through a hole 13 in a cap 12, the top end of the plunger 11 being fastened to an actuator 15.
  • the cap 12 and the actuator 15 are engageable with each other by means of two threaded portions 16 and 17.
  • the housing 10 is provided with a shoulder 18. Located between the shoulder 18 and the cap 12 is a container cap 19 of the emulsion container (not shown in the drawings).
  • the plunger 11 is provided with a piston device 21.
  • the housing 10 has a tail tube 22 which is provided with a valve 23 and a dip tube 24 which is in contact with the emulsion held in the emulsion container.
  • the known dispensers are prone to leakage when they are tilted from a vertical position.
  • One aim of the present invention is to provide an emulsion dispenser which facilitates the recycling of a discarded dispenser.
  • Another aim of the present invention is to provide an emulsion dispenser that reduces leakage.
  • the present invention provides a dispenser comprising a housing containing a plunger, a resilient member having a cavity, and an actuator having a dispensing tube, said actuator being connected to the top end of said plunger for moving the plunger within said housing to compress said resilient member to reduce the volume of said resilient member cavity such that, in use, any emulsion contained within said resilient member cavity is expelled through said actuator dispensing tube via said plunger, characterised in that said resilient member is formed of a recyclable plastics material.
  • said resilient member is a concertinable hollow tube.
  • the present invention provides a dispenser comprising a housing containing a plunger, a resilient member having a cavity, and an actuator having a dispensing tube, said actuator being connected to the top end of said plunger for moving the plunger with said housing to compress the resilient member to reduce the volume of said resilient member cavity such that, in use, any emulsion contained within said resilient member cavity is expelled through said actuator dispensing tube via said piston, characterised in that said dispenser further comprises a rod stem having an enlarged end, the rod stem extending through the resilient member cavity with the enlarged end protruding from the resilient member and wherein said dispenser further includes a flange at the head of the resilient member such that when the resilient member is in its uncompressed state, said flange abuts the enlarged head thereby sealing the cavity of the resilient member.
  • the first and second aspects are combined.
  • an emulsion dispenser embodied in the present invention comprises a housing 30, an engagement cap 39, a plunger 31, a first valve 41, a second valve 43, and a resilient member 45, made of plastic.
  • the dispenser is provided with a collar 32 having a through hole 33.
  • the housing 30 is provided at its top end with a threaded section 38.
  • the housing 30 is provided at its bottom end with a tail tube 42 and a dip tube 44 in contact with emulsion held in a container.
  • the engagement cap 39 is disposed between the collar 32 and the threaded section 38 of the housing 30 and is for engaging the housing 30 with the top end of the emulsion container (not shown in the drawings).
  • the plunger 31 is disposed in the housing 30 such that a top end of the plunger 31 protrudes from the collar 32 via the through hole 33 so as to fasten with an actuator 35 which is provided with a dispensing tube 34.
  • each valve 41 and second valve 43 are disposed respectively in the upper segment of the plunger 31 and the tail tube 42 of the housing 30.
  • each valve comprises a ball that rests in a valve seat.
  • the resilient member 45 is disposed in the housing 30 such that one end of the resilient member 45 abuts the bottom end of the plunger 31 and the other end of the resilient member 45 abuts the inner bottom wall of the housing 30.
  • the resilient member 45 may be of a plastic spiral tube, as shown Fig. 9.
  • the resilient member is preferably a hollow tube having a central cavity that is concertinable to a reduced height, thus decreasing the volume of the cavity.
  • the plunger 31 is provided at the bottom end with an outer threaded portion 51 and is fitted into a sleeve 47 such that the outer threaded portion 51 cooperates with an inner threaded portion 52 of the sleeve 47 as shown in Figure 5. This cooperation maintains the dispenser in a non-dispensing state until the actuator and plunger 31 are rotated to disengage the threaded portions to some extent as seen in Figure 6.
  • a stop portion 53 Located between the outer wall of the sleeve 47 and the guide tube 56 of the collar 32 is a stop portion 53 to prevent the sleeve 47 from turning when the plunger 31 is rotated within the housing to disengage the threaded portions.
  • the collar 32 is provided with a guide tube 56 extending therefrom and has a flange 55.
  • the guide tube 56 is used to guide the sleeve 47 when in motion.
  • the bottom end of the housing 30 is provided with a rod seat 58 having a rod stem 57 and an enlarged end 59 extending from the rod stem 57 such that the enlarged end 59 extends through an aperture in a flange 46 at the head of the resilient member 45.
  • the flange 46 and the enlarged end 59 form a leakproof seal to prevent the escape of the emulsion when the resilient member is in its uncompressed state even if the emulsion container is inadvertently knocked over. This can be seen in Figs. 10 and 11.
  • the enlarged end 59 of the rod stem 57 abuts the flange 46 of the resilient member, to prevent the passage of emulsion from the resilient member cavity into the plunger 31.
  • Fig. 8 shows a second preferred embodiment where the first and second valves include a funnel-shaped valve seat.
  • FIG. 12 to 15 A third embodiment of the emulsion dispenser is shown in Figs. 12 to 15.
  • the third embodiment is the same as the first embodiment except that the plunger 31 and sleeve 47 do not have threaded portions.
  • the collar 32 is provided with a thread 37 that cooperates with a thread 36 on the actuator 35 to secure the dispenser in a non-dispensing position as shown in Fig. 13.
  • the threads are disconnected and the actuator is raised from the collar by the resilience of the resilient member as shown in Fig. 14.
  • the plunger 31 has a retaining projection 48 which cooperates with a retaining slot 49 on the sleeve to engage the two parts ready for dispensing.
  • the dispenser dispenses in the following manner.
  • the actuator 35 is depressed and the plunger 31 and sleeve 47 move within the housing causing compression of the resilient member 45.
  • the resilience of the resilient member causes the plunger, sleeve and actuator to return to their original position and, as they do so, emulsion is drawn upwards through the dip tube 44, through the second valve which will be forced open by the flow of emulsion, and into the cavity of the resilient member.
  • the first valve will remain closed during this step.
  • the dispenser Whilst reference is made to use of the dispenser for emulsion, the invention is not limited to such use.
  • the dispenser may also be used for any other viscous liquid e.g. soap or food products.
