Abstract
Description
- The present invention relates generally to a dispenser, and more particularly to a dispenser for dispensing an emulsion or similar substances hereinafter, for brevity, referred to as emulsions.
- As shown in Figs. 1 and 2, an emulsion dispenser of the prior art comprises a
housing 10 in which aplunger 11 is disposed such that the top end of theplunger 11 extends through ahole 13 in acap 12, the top end of theplunger 11 being fastened to anactuator 15. Thecap 12 and theactuator 15 are engageable with each other by means of two threadedportions housing 10 is provided with ashoulder 18. Located between theshoulder 18 and thecap 12 is acontainer cap 19 of the emulsion container (not shown in the drawings). Theplunger 11 is provided with apiston device 21. Thehousing 10 has atail tube 22 which is provided with avalve 23 and adip tube 24 which is in contact with the emulsion held in the emulsion container. - When the
actuator 15 is pressed as shown in Figure 1, the emulsion is dispensed in handy units or portions via anexit 14 of theactuator 15. Theplunger 11 is provided at its lower end with arecovery spring 25 serving to provide theplunger 11 with a recovery spring force enabling theplunger 11 to return to its original position in thehousing 10 when the pressure on theactuator 15 is removed (as shown in Figure 2). With the exception of therecovery spring 25 which is made of metal, other component parts of the prior art emulsion dispenser are made of a plastic material. Themetal spring 25 causes problems in the process of recycling the discarded dispensers of the prior art. In other words, themetal spring 25 and other component parts of the prior art dispenser cannot be separated in a cost-effective manner in the recycling of the prior art dispensers. - Furthermore, 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.
- Accordingly, in a first aspect, 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.
- In this way, recycling of discarded dispensers is greatly facilitated.
- Preferably said resilient member is a concertinable hollow tube.
- In a second aspect, 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.
- In especially preferred embodiment, the first and second aspects are combined.
- Preferred embodiments will now be described with reference to the accompanying drawings.

- As shown in Figs. 3 to 11, an emulsion dispenser embodied in the present invention comprises a
housing 30, anengagement cap 39, aplunger 31, afirst valve 41, asecond valve 43, and aresilient member 45, made of plastic. - The dispenser is provided with a
collar 32 having a throughhole 33. Thehousing 30 is provided at its top end with a threadedsection 38. Thehousing 30 is provided at its bottom end with atail tube 42 and adip tube 44 in contact with emulsion held in a container. - The
engagement cap 39 is disposed between thecollar 32 and the threadedsection 38 of thehousing 30 and is for engaging thehousing 30 with the top end of the emulsion container (not shown in the drawings). - The
plunger 31 is disposed in thehousing 30 such that a top end of theplunger 31 protrudes from thecollar 32 via the throughhole 33 so as to fasten with anactuator 35 which is provided with adispensing tube 34. - The
first valve 41 andsecond valve 43 are disposed respectively in the upper segment of theplunger 31 and thetail tube 42 of thehousing 30. In the embodiment shown in Figures 3-7, each valve comprises a ball that rests in a valve seat. - The
resilient member 45 is disposed in thehousing 30 such that one end of theresilient member 45 abuts the bottom end of theplunger 31 and the other end of theresilient member 45 abuts the inner bottom wall of thehousing 30. Theresilient 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 threadedportion 51 and is fitted into asleeve 47 such that the outer threadedportion 51 cooperates with an inner threadedportion 52 of thesleeve 47 as shown in Figure 5. This cooperation maintains the dispenser in a non-dispensing state until the actuator andplunger 31 are rotated to disengage the threaded portions to some extent as seen in Figure 6. - Located between the outer wall of the
sleeve 47 and theguide tube 56 of thecollar 32 is astop portion 53 to prevent thesleeve 47 from turning when theplunger 31 is rotated within the housing to disengage the threaded portions. - The
collar 32 is provided with aguide tube 56 extending therefrom and has aflange 55. Theguide tube 56 is used to guide thesleeve 47 when in motion. - The bottom end of the
housing 30 is provided with arod seat 58 having arod stem 57 and an enlargedend 59 extending from therod stem 57 such that the enlargedend 59 extends through an aperture in aflange 46 at the head of theresilient member 45. Theflange 46 and the enlargedend 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 enlargedend 59 of therod stem 57 abuts theflange 46 of the resilient member, to prevent the passage of emulsion from the resilient member cavity into theplunger 31. - Fig. 8 shows a second preferred embodiment where the first and second valves include a funnel-shaped valve seat.
- 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 andsleeve 47 do not have threaded portions. - Instead, the
collar 32 is provided with athread 37 that cooperates with athread 36 on theactuator 35 to secure the dispenser in a non-dispensing position as shown in Fig. 13. To allow dispensing, the threads are disconnected and the actuator is raised from the collar by the resilience of the resilient member as shown in Fig. 14. Theplunger 31 has aretaining projection 48 which cooperates with aretaining slot 49 on the sleeve to engage the two parts ready for dispensing. - For all embodiments, the dispenser dispenses in the following manner. The
actuator 35 is depressed and theplunger 31 andsleeve 47 move within the housing causing compression of theresilient member 45. As the actuator is released, 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 thedip 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. - Once the resilient member cavity is filled with emulsion, a second depression of the actuator causes the
plunger 31 andsleeve 47 to compress theresilient member 45 and decrease the volume of the cavity. The second valve remains closed whilst the first valve is opened. The emulsion in the resilient member is forced upwards through theplunger 31, through thefirst valve 41 which will be forced open by the flow of emulsion and out of the dispensingtube 34 of theactuator 35. - 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.
