Description

Dispenser

Field

The present invention relates to a dispenser, in particular but not exclusively to a dispenser for dispensing a liquid.

Background

A smoking-substitute device is an electronic device that permits the user to simulate the act of smoking by producing an aerosol mist or vapour that is drawn into the lungs through the mouth and then exh.alt.xl. The inhaled aerosol mist or vapour typically bears nicotine andier other flavourings without the odour and health risks associated with traditional smoking and tobacco products. In use, the user experiences a similar satisfaction and physical sensation to those experienced from a traditional smoking or tobacco product, and exhales an aerosol mist or vapour of similar appearance to the smoke exhaled when using such traditional smoking or tobacco products.

A smoking-substitute device generally uses heat and/or ultrasonic agitation to vaporize a solution comprising nicotine ancVor other flavouring, propylene glycol and/or glycerine-based base into an aerosol mist of vapour for inhalation. A person of ordinary skill in the art will appreciate that the twit -smoking-substitute device" as used herein includes, but is not limited to, electronic nicotine delivery systems (ENDS), electronic cigarettes, e-cigarettes, e-cigs, wiping cigarettes, pipes, cigars, cigarillos, vaporizers and devices of a similar nature that function to produce an aerosol mist or vapour that is inhaled by a user. Some electronic cigarettes are disposable; others arc reusable, with replaceable and refillable parts.

Smoking-substitute s typically resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end through which the user can draw the aerosol mist or vapour for inhalation. These devices usually share several common components: a power source such as a battery, a reservoir for holding the liquid to be vaporized, a vaporization component for atomizing and/or vaporizing the liquid and to thereby produce an aerosol mist and or vapour, and control circuitry operable to actuate the vaporization component responsive to an actuation signal from a switch operative by a user or configured to detect when the user draws air through the mouthpiece by sucking or inhaling.

The reservoir may be either a replaceable or refillable container that is coupled to, or located. in, the main body of the smoking-substitute device and that is typically made of a resilient plastic material such as high-density polypropylene. The reservoir generally contains a t ickine material in which the stored but may just he a storage space without any wicking material. Once the replaceable or refillable reservoir is emptied it must either be replaced or refilled.

Replaceable type reservoirs are typically provided in the form of a pm-filled cartridge that can he securely and removably engaged to, or within, the cylindrical body of the smoking-substitute device. These reservoir and vaporization elements may also he integrated into a single component commonly known as a "eartornizer" that may he disposable or refillable. Additionally, replaceable type reservoirs may also be integrally formed with the mouthpiece.

1 0 In order to fit a replaceable type reservoir to, or within, the main body of a smoking-substitute device, features of the main body are configured to engage with complementary features formed on a portion of the reservoir to securely and removably couple the reservoir to the main body of the smoking substitute device and to thereby prevent the accidental or unintended separation of the reservoir from the smoking-substitute device. These complementary features typically secure the reservoir to the main body of the smoking-substitute device with a close or interference fit and the fitting step causes a portion of the reservoir to pierce the reservoir to permit liquid to be dispensed.

Alternatively, and most commonly, users utilise refillable type MSC,: \ 'Typically, the refillable reservoir of the smoking-substitute device is refilled by dispensing liquid from a dispenser that commonly resembles the small dropper bottles used for dispensing eye drops.

Refill dispensers are preferred principally for their low cost.

The ingredients of the liquid fOr producing the aerosol mist or vapour in smoking-. substitute devices vary. widely, but typically include water and flavourings in a propylene glycol and/or glycerol base. Nicotine may also be included in solutions intended to fulfil a nicotine replacement role, without the harmful products associated with tobacco smoke.

A person of ordinary skill in the art will appreciate that the term "liquid" as used herein, may include, but is not limited to, any liquids, gels, powders and gases together with liquids comprising mixtures of liquids, gels, powders and gases that are capable of being atomized or vapourized whether or not using heat and/or ultrasonics. Additionally, the term "liquid" as used herein may also include, but is not limited to, powders capable of being entrained in a fluid flow, for example an airflow.

When refilling the reservoir from a dispenser, the user typically drips liquid from the outlet liquid-dispensing tip of the dispenser into an inlet of the reservoir by squeezing the wails of the dispenser. Any wicking material in the reservoir then absorbs the dispensed liquid or e space in the reservoir is simply filled with the dispensed liquid. Since the diameter of the inlet on the smoking-substitute device is typically quite narrow it is important that the liquid-dispensing tip of the dispenser is correctly aligned to prevent spillage.

Additionally, the user must correctly judge the pressure with which the dispenser should be squeezed to controllably expel liquid from the liquid-dispensing tip. furthcrmore, as the user releases the bottle air is sucked in through the liquid-dispensing tip to replace the volume of liquid that has just been dispensed, but can also suck recently dispensed from the reservoir and back into the dispenser causing droplets of liquid to be expelled inadvertently from the reservoir. Consequently, this refill technique is cumbersome and typically results in spillages of oily liquid, which has an oily consistency, and so some users have found that utilizing a syringe to draw liquid from the outlet of the dispenser before injecting it through the inlet of the reservoir is more convenient. However, such a procedure utilises a sharp such as a hypodermic needle arrangement and puts a user at risk of injury from the sharp piercing the skin and also contamination of their skin and potentially sub-dermal layers with the liquid due to its presence on the needle.

A method of refilling the reservoir of a smoking-substitute device from a dispenser is disclosed in US 2014/0283946 Al {Cribs, et al). This published patent application describes a cap that fits over the liquid-dispensing tip ofa standard eyedropper type refill dispenser. The cap has a first portion with a bore into which the liquid-dispensing tip of a standard 0 bottle is received, and an inner annular wall that is threaded, such that a gap is disposed between the liquid-dispensing tip and the threaded portion of the inner annular wall. When liquid is to be dispensed into the reservoir to refill the reservoir, the first portion of the cap is screwed onto a reciprocal threaded outer portion of the smoking-substitute device. When fully engaged the first portion of the cap is substantially sealed against the inlet of the reservoir of the smoking-substitute device to permit liquid to flow between the dispenser and the reservoir and alleviate leakage. Additionally, it is difficult to determine the amount of liquid input to the reservoir, unless of course the reservoir wails are transparent. Even so, if it were desired to input only a specific amount of liquid into the reservoir a user will still End it difficult even if the walls of the reservoir were transparent because the nature of a squeezable bottle for dispensing liquid into the reservoir results in an inaccurate volume of liquid being dispensed, not least because the "suck back" effect of the bottle to replace the volume of liquid dispensed with air.

The popularity and use of smoking-substitute devices has grown rapidly in the e past few years. Although originally marketed as an aid to assist habitual smokers wishing to quit traditional smoking and tobacco products, consumers are increasingly viewing smoking substitute devices as desirable lifestyle accessories. This has caused concern that smoking-substitute devices may he becoming fashionable in certain sections of the population, and that their use may as a consequence be attractive to children and young adults, who may subsequently graduate to traditional smoking and tobacco products.

There is also significant orFgoing scientific debate about the long-tertrls effects health from the prolonged use of smoking-substitute devices, and the inhalation of atomized mists aUd/br vapours comprising nicotine constituents. However, it is generally accepted that the levels of toxicants consumed by users of such smoking-substitute devices is a fraction of those consumed by users of traditional. smoking and tobacco products. See, for example, John H. Lauterbach et al, "Suggested Protocol for Eislimaiion of ficarndni and Potentially Harmfid Constituents in Alai tlerusols generated by Electronic Delivery Systems (ENDS)", presented at SOT, San Francisco, Calif, Mar. 10-16, 2012 (httpilibigtoxdoe,ehostservices113 Ott/Sot2012posterl S6daspresented.pdf) and hereby incorporated by reference.

Nonetheless, the health issues connected with the prolonged. use of smoking-substitute devices is increasingly receiving negative press coverage and is the subject of much political debate, One area of particular concern is the quality and provenance of many liquids presently available of the market. Concerns raised, particularly by the medical profession, also: focus on the lack of information available consumers regarding the use of smokiitg-substitute devices and associated liquids that prevent them from making informed decisions regarding their use.

To address safety and OUality concerns relating to traditional smoking and tobacco products, the World Health Organisation (WHO) published the Framework Convention on Tobacco Control (FCTC) in May 2003. The FCTC provisions arc intended to regulate the sale and marketing of tobacco and tobacco-alternative products, the disclosure of information relating to such products, the packaging and labelling of such products, and the advertising of such products. These provisions are binding on the European Union:CLIO and its' Member States who have adopted a set of guidelines for the implementation of the FCTC provisions by consensus during a series of subsequent conferences. Although, the FCTC did not ciliate the market for smoking-substitute devices, the governments of several Member es have decided that it would be appropriate to adapt the current legislation 'resulting from the FCTC and that relates to traditional smoking and tobacco products to incorporate such smoking-substitute devices.

in Europe efforts to adapt the existing legislation followed the publication of various reports and advic0 received front the Scientific Committee on Newly Identified Health Risks (SCEN1F1R) on smokeless tobacco products and tobacco additives. The European Parliament and Council of the European Union has proposed repealing Directive 2001/37/EC and replacing it with Directive 2014/401it on April 3, 2014 (Tobacco Products Directive or TPD). Although still to be enacted into the national laws of the Member States of the EU and not expected to come into force until May 2016, the TPD proposes regulations applicable to smoking-substitute devices that will: g limit the risks of inadvertent exposure to nicotine by setting maximum sizes for etill reservoirs, containers, tanks and cartridges (Article 20,13(a)) * limit the concentration of nicotine in the liquid to 20 rrigtml (Article 203(1)).

prohibit the use of certain additives in the liquid (Article 20.3(c)) s/ require that only high-purity ingredients are used in the mane cure uids (Article 203(d)).

require that all ingredients (except nicotine) do not pose a risk to human health in heated or unheated form (Article 20.3(c)) * require that all smoking-substitute devices deliver doses of nicotine at consistent levels under normal conditions of use (Article 20.3(1)) * require that all products include child and tamper-proof abel fasteners and opening mechanisms (Article 20.3(g)).

* require that all products meet certain safety and quality standards and to ensure that products do no break or leak during use or refill (penultimate and. final sentences, paragraph 41 of the recitals).

011C area of particular concern to consumers and regulators is that the increased availability of smoking-substitute devices and refill liquids in supermarkets and other outlets may create a health risk particularly if they fall into the hands of children. Although these liquids typically comprise nicotine in concentrations of less than or equal to 3.6% of the liquid which is generally regarded as safe and merely a stimulant, Nicotine in much higher concentration has in the past been used as an insecticide and in concentrations of 50-100 mg can be harmful to humans. Nonetheless, solutions comprising nicotine are treated as toxic by postal services and carriers, and so appropriate precautions are required when handling and storing nicotine in bulk.

Aspects and embodiments of le invention were devised with the foregoing in mind.

Summary

eon n a first aspect there is provided a dispenser for dispensing a liquid, a reservoir for storing a liquid to be dispensed; a manually operative pump arrangement disposed at a first end region of the reservoir; a conduit extending from the pump arrangement to a second end region of the reservoir distal the first end region, the conduit configured for communicating reservoir contents from the second end region to the pump arrangement, a dispense conduit extending from the pump arrangement and comprising a dispense aperture at an end region thereof, the dispense aperture in liquid communication with the pump arrangement; and an open ended tube ending in a direction away from the pump arrangement and configured to surround the dispense conduit, wherein the open ended tube extends to a position such that the open end thereof is at least coterminous with an dispense aperture end of the dispense conduit and actuation of the pump arrangement causes transfer of reservoir contents from the reservoir to the dispense aperture end of the dispense conduit.

Such a dispenser provides an integrated reservoir and dispense pump arrangement which the dispense conduit may be protected from inadvertent contact, for example by a user, thereby inhibiting the likelihood of contamination of the dispense conduit. Inhibiting contamination of the dispense conduit is particularly important if the dispenser is used for dispensing contents to be consumed by human being, for example a medicament or a smoking substitute vapour which are ingested or inhaled by a human being.

In one or more embodiments the open ended tube extends to a position beyond the dispense aperture end of the dispense conduit thereby enhancing protection of the dispense conduit from inadvertent contact.

In one or more embodiments the dispense conduit is configured to interface with a complementary arrangement in the container to be filled to deliver reservoir contents into the container. Such an interface between the dispense conduit and a container to be filled may reduce the likelihood of spillage andlor contamination of the reservoir contents during transfer from the dispense conduit to the container to he filled. in a particular embodiment, the dispense conduit is configured to penetrate into a container to be filled to deliver reservoir contents into the container. Penetration into the container to be filled further reduces the likelihood of spillage and contamination of the reservoir contents as they are transferred to the container. Penetration of the dispense conduit into the container provides for delivery of the reservoir contents from the dispense conduit nto the container ereby avoiding spillage of the reservoir contents during filling, In a particularly convenient one or more embodiment, the dispense conduit is configured to pierce a membrane of the container to be filled to protrude into the container to be filled to deliver reservoir contents into the container. Such a piercing arrangement is mechanically straightforward and may thr example comprise a dispense conduit configured n a similar manner to that of a hypodermic needle. In such one or more embodiments inhibiting inadvertent contact with the dispense conduit becomes more important than with a non-shop dispense conduit in order to avoid pinprick or "stick" injury to a user and/or body 0 fluid contamination, such as blood contamination, of the dispense conduit.

Suitably, one or more embodiments are further configured to receive a cap to dose the open ended tube, such as a child safety cap. Further protection of the dispense conduit by a cap is particularly important for an embodiment having a sharp dispense conduit.

Typically, thx pump arrangement is resiliently biased towards a closed position which facilitates single-handed operation and reduces the likelihood of leakage when the pump dispenser is not in use, Additionally, such a bias requires a positive pressure to operate the pump arrangement thereby reducing the likelihood of inadvertent actuation and dispensing of the reservoir contents.

In one or more embodiments, the pump arrangement comprises an abutment surface configured to engage with a complementary surface of a container to be filled and wherein application of a force to the abutment surface actuates the pump arrangement. In such one or more embodiments, a container to be filled may be brought into contact with the abutment surface and a force applied to the container to he filled by user to actuate the pump arrangement. With such a configuration, contact by user with the dispense conduit and/or pump arrangement is further inhibited by use of the container to be filled as an intermediate member for actuating the pump arrangement. Typically, application of the force is against the resilient bias.

In one or more embodiments. the open ended tube is profiled so as to guide container to be filled into engagement with the dispense conduit. Such one or more embodiments assist in location of the dispense conduit with the interface fo,niation of a container to be filled thereby avoiding spillage or wastage of reservoir contents. Suitably, the open ended tube is profiled so as to provide a transition fit for engagement of a container to be filled for reciprocal movement of the container to be filled with respect to the open ended tube. Such a transition fit assists in controllably guiding a container to be filled in a reciprocal motion within the open ended tube for effecting actuation of the pump arrangement through contact of respective abutment surfaces of the pump arrangement. Moreover, the container to be filled may be positively located in the open ended tube.

In one or more embodiments, the inner wall of the open ended tube is profiled so as to guide a container to be filled. Insertion of a container to be filled into the open ended tube provides for detail of profiling to be interior to the open ended tube thereby providing an uninterrupted outer surface of the open ended tube. Such an uninterrupted outer surface may assist in the fitting of a cap over the open end of the open ended tube and/or improve the aesthetics but the open ended tube when viewed from the outside.

In a particularly convenient one or more embodiment, the open ended tube is profiled so as to receive a mouthpiece for a smoking substitute device. In such a one or more embodiment the open ended tube may be profiled to provide a complementary cross-section such as for a mouthpiece for a smoking substitute device. Profiling the open ended tube a certain configuration limits the insertion of containers to be filled to those containers which can fit within the profile thereby providing a mechanism for inhibiting the use of containers to be tilled not intended for use with the dispenser. Profiling may be sufficiently detailed, so as to substantially restrict use of containers to be filled to those having an exact complementary configuration, in particular complementary cross-sectional configuration, to the open ended tube.

Profiling of the open ended tube may also provide a mechanism by which actuation of the pump and thereby dispensing of reservoir contents may only he achieved by use of a suitably shaped member, such as a suitably shaped container to be tilled, thereby avoiding inadvertent actuation of the pump and dispensing of the reservoir contents.

Additionally or optionally, the open ended tube may be configured with a locking or a 25 positive engagement mechanism configured to permit a reciprocal movement of the container to be filled when engaged therewith, Additionally or optionally, the pump arrangement may comprise a locking or positive engagement mechanism, for example as part of andlor associated with the abutment surface, interoperable with a complementary mechanism on. the container to be filled to avoid inadvertent separation of the container to be filled from the 30 pump arrangement.

In one or more embodiments, a surface of the open ended tube is coated with an antibacterial coating, for example MicrobanTM. This is particularly beneficial where the container to be filled comprises a mouth piece which is inserted into the open ended babe as the exterior of the mouthpiece is cleaned at is it serted into and sake the open ended tube.

Suitably, the pump mechanism dimensions are gured to deliver a measured dose of reservoir contents for a full pump stroke length. Delivery of such a measured dose is particularly usefill were the reservoir contents comprise a medicament. It is also useftil where the measured dose is an equally divided amount of the volume of the container to be filled storage region since a user can then actuate the pump a particular number of times to reliably fill storage region.

To assist in measuring a stroke length the dispenser may be configured to provide 10 feedback indicative of reaching a maximum stroke length, wherein the feedback may be one or more of tactile, visual and audio feedback.

Viewed from a second aspect, there is provided a container operative srwith the dispenser as described above for filling the container, the container comprising: a storage cavity for storing reservoir contents dispense° to the container from the 15 dispenser; an interface formation configured to receive the dispense conduit dispenser to open a conduit between the storage cavity and pump arrangement to permit ansfer of reservoir contents from the pump arrangement to the storage cavity responsive to actuation of the pump arrangement; and wherein the interface formation is disposed in an interface e container configured to fit to the open ended tube in order for the dispense conduit o engage with the interface In one or more embodiments, the interface fommtion comprises a rupturable membrane which is particularly suited to use with a dispenser having a sharp dispense conduit. Advantageously, the rupturable membrane comprises a self-scaling material, for example silicone, which obviates the need to provide a cap over a ruptured membrane to avoid leakage from the container to be filled due to the ruptured membrane. In particular, the membrane may he made entirely of silicone.

Suitably, the interface section is configured to be insertable into the open ended tube and in particular is configured to form a transition fit with the open ended tube. A fit assists in controllably guiding the interface section into the open ended tube such that it may interface with the dispense conduit and also in controllably guiding reciprocal motion of the interface section within the open ended tube for actuation of the pump arrangement.

In one or more embodiments, the interface section comprises an abutment surface configured to contact a complementary abutment surface of the pump arrangement of the dispenser such that reciprocal movement of the container in the open ended tube may actuate the pump arrangement. Thus, the container may be contacted by user in order to actuate the pump arrangcment thereby decreasing the likelihood of a user coining into contact with. the dispense conduit or pump arrangement due to the intermediary provided by the interface section.

The interface section may comprise formations complementary to formations in the open ended tube and/or pump arrangement. for providing positive engagement there with in order to inhibit inadvertent separation of the container from the dispenser during operation.

The interface section typically comprises a hollow member at one end of which is the interface formation such that in use a dispense conduit can enter into the hollow member to reach the interface fonnation.

Suitably, the container may be configured as a container for a nicotine vapour precursor liquid for a smoking substitute device, for example configured as a cartomiser. In embodiments in which the container is configured for smoking substitute device such as a cartomiser, it is particularly convenient for the interface section to be configured as a mouthpiece. However, the interface section may be configured as a mouthpiece for use with containers other than for smoking substitute devices.

Viewed from a third aspect, there is provided a kit of parts for forming an assembly for filling a container, comprising a dispenser as described above and a container as described above. Such a kit of parts may be provided to a consumer packaged together for the consumer's convenience.

Viewed from a fourth aspect, there is provided a kit of parts for forming a dispenser as described above, comprising: a hollow tube closed at one end and configured at a position intermediate the closed-end and open-end to provide a support for a manually operative reciprocal pump arrangement, the hollow tube configured to form a reservoir between the position and closed end for storing contents to be dispensed; a manually operative reciprocal pump arrangement; a dip tube coupleable to the pump arrangement; and a dispense conduit coupled to the pump arrangement.

Such a kit of parts s a useful collection of components for assembling a dispenser.

latetailed Description of the Invention

Fig. 1 shows a dispenser 10 for dispensing a liquid dispenser 10 can be used to fill or re-fill containers, such as, for example, cartomisers for e-cigarette devices.

The dispenser 10 comprises an elongate, hollow, cylindrical housing 12, which is closed at a first end and open at a second, opposite end, and a cap 14 for closing off the second, open end.

Fig. 2 shows the dispenser 10 with the cap 14 removed from the housing I 2 to expose an aperture 16. Aperture 16, located at the second, open end of housing 12, is configured for receiving a container to be filled and forms an open end of open ended tube 18. The open ended tube 18 is disposed within the housing 12.

When the cap 14 is removed, an end of a container to be filled can be inserted into the open ended tube 18 of the dispenser 10 via the aperture 16.

Fig. 3 illustrates, in exploded form, the elements of dispenser housing which is formed of a reservoir portion 12a and a dispense conduit housing portion 12b, cap 14 and a pump device 20.

The pump device 20 comprises an intake conduit fluid communication with a pump arrangement 24. Pump arrangement 24 is conf ion at, adjacent, or about a first end of the reservoir portion 12a and is in fluid communication with a dispense conduit 2.6.

Intake conduit 22.. (also known as a "dip tube") extends from the pump arrangement 24 so that, when the pump device 20 is located within housing 12, the intake conduit 22 extends to a second end of the reservoir portion 12a distal the first end. The intake conduit 22 is configured for communicating contents in the reservoir portion 12a from the second end thereof to pump arrangement 24.

The intake conduit 22 comprises a notch across its walls (not shown in Fig. 2, but see feature 32 in Figs. 7 and 10) to ease suction of liquid from the second end of the reservoir portion 12a.

Dispense conduit 26, such as, for example, a dispense tip, extends from the pump arrangement 24 and comprises a dispense aperture (not shown) at an end thereof The perture is iax fluid communication with the pump arrangement 24.

When pump device 20 is located ing 12, the open ended tube (not shown in Fig. .3) extends in a direction a the primp arrangement 24 and is configured to surround the dispense conduit 26. The open ended tube extends to a position such that the open end thereof is at least coterminous with the dispense aperture end ("tip") of the dispense conduit 26 and actuation of the pump arrangement 24 causes transfer of reservoir contents from the reservoir portion 12a to the dispense aperture end of the dispense conduit 26.

The pump arrangement 24 comprises valve seat element 2400, a hollow cylindrical member 2410, an operating rod 2440, a body portion 2450 and a pump actuator 2460. The pump actuator 2460 is in fluid communication with body portion 2450 by way of operating rod 2440, and valve seat element 2.400 is in fluid communication with body portion 2450 by way of hollow cylindrical member 2410. The valve seat element 2400 is in fluid communication with intake conduit 22 and the pump actuator 2460 is in fluid communication with the dispense conduit 26. 'Thus, a fluid passage is provided through the pump arrangement to provide a fluid passage from a remote end of the intake conduit 22, via the pump arrangement, to a remote end of the dispense conduit 26.

Referring now to Figs. 4 to 6, a pump device 20 suitable for use in a dispenser according to one or more embodiments of the present invention is shown. it will be apparent to those skilled in the art that the pump device 20 illustrated in Figs. 4 to 6 is merely one example of many suitable types of pump device that could he employed in the dispenser of an embodiment of the preset invention.

Pump device 20 comprises intake conduit coupled to valve seat element 2400, which is coupled to hollow cylindrical member 2410. The pump device further comprises an upper valve 2420, a piston member 2430, operating rod 2440, a body portion 2450, and a pump actuator 2460. Cylindrical member 2410 has mounted thereunder the valve seat element 2400 and the intake conduit 22 to be placed in reservoir portion 12a of dispenser 10 and includes a reservoir chamber 2412, a top engaging portion 2414, an annular flange 2416 positioning thereon body portion 2420 to be seated against seat portion 12c, which is a flange disposed around the interior of reservoir portion 12a at said first end thereof. A lower portion of the cylindrical member 2410 is configured for coupling to said valve seat element 2400 in which is located a ball 2418 Upper valve 2420 includes a body portion 2422 having a bottom positioning ring 2422c and two top concentric annular grooves 2422a, 2422b triangular crosssection, upper engaging medium 2424 having three upward rectangular wings 2424a respectively having three top inner triangular indentations 2424b to facilitate passing the liquid from three passages 2424c defined by wings 2424a to operating rod 2440, and a downward engaging rod 2426 having a bottom end 2426a split into three fingers 2426b. A compression spring 2428 is positioned in cylindrical member 2410 and mounted between positioning ring 2422c and valve seat element 2400, Piston 2430 includes a through hole 2432, t kv concentric bottom annular teeth 2434, 2436 respectively ngageable with grooves 2422a, 2422h, a top inner annular indentation 2438 and a top outer annular indentation 2439 and is sleeved in cylindrical member 2410 to be movable along the inner wall thereof.

Operating rod 2440 is hollow and includes a top end 2441, a bottom end having a bottom annular projection 2442 engageable in inner indentation 2438 when operating rod 2440 is pressed downward, and a through hole which includes a shoulder surface 2444 defining thereabovc an upper hole 2446 and thereunder a lower hole 2448 receiving therein the upper portion of upper engaging medium 2424 bearing against shoulder surface 2444.

Body portion 245(1 includes a through hole 2452, an annular engaging piece 2454 of inverted L-shaped cross-section securely, but moveably receiving therein operating rod 2440, and an engaging top 2456 fixed to top engaging portion 2414.

In operation, as shown in Fig. 10, when pump actuator 2460 and operating rod 2440 are pressed downward, operating rod 2440 will disengage upper valve 2420 from piston member 2430 to thus connect reservoir chamber 2412 with lower hole 2448 before bottom annular projection 2442 matches with inner identation 2438. If pump actuator 2460 and operating rod 2440 are further pressed downward, piston 2430 will be moved downward accordingly and thus the airior liquid in reservoir chamber 2412 will pass through passages 2424c, hole 2446, pump actuator 2460 and dispense conduit 26 to be discharged (denoted by the arrows in the figure). After pump actuator 2460 and operating rod 2440 reach their lowest positions and are released, compression spring 2428 will again match annular teeth 2434, 2436 against annular grooves 2422a, 2422b respectively and displace upward piston 2430 to thus form a vacuum in reservoir chamber 2412 to in turn allow ball 2418 to leave a valve seat in valve seat clement 2400 to suck from intake conduit 22 the liquid in the reservoir portion 12a into reservoir chamber 2412. if pump actuator 2460 and operating rod 2440 are pressed downward again, the liquid in reservoir chamber 2412 will he communicated through the conduit through pump actuator 2460 and discharged through dispense conduit 26.

The assembled dispenser 10 can he seen in cross section view in both Figs. 7 and 10, both of which illustrates the dispenser 10 as viewed in cross section along line A-A of Fig. 1.

Fig. 7 illustrates the dispenser 10 in a non-use state and Fig. 10 (as described above) illustrates the dispenser during a stage of operation.

As can he seen in Fig. 10, dispense conduit 26 extends through an perture in the container 28 to be tilled and into a reservoir of the container 28.

Fig. 8 is similar to Fig. 2 in that it shows the dispenser 10 the cap 14 removed from the housing 12 to expose apeiture 16. In this figure, a container 28 to he filled is located adjacent aperture and is disposed for* insertion into aperture 16 to extend into open ended tube 18.

Fig. 9 shows the container 28 to e with a portion thereof located dispenser 10.

The container 28 can he filled with liquid contained in the reservoir portion 12a of housing 12 by exerting a force (in the direction denoted by arrow X in the figure) on the exposed end of the container 28 to urge container 28 from a rest position into the dispenser 10. This action causes an end of the container 28 within the dispenser to abut an end of the pump arrangement shown in Fig. 9, but see feature 30 in figure 10), Continued depression of container 28 relative to the dispenser 10 against the action of compression spring within the pump arrangement causes actuation of the pump arrangement until the pump actuator is in a fully depressed position, Actuation of the pump arrangement causes liquid to he communicated via the dispense conduit (not shown), which extends through an aperture of the container 28 into a reservoir thereof, to deliver liquid to the reservoir of the container 28.

Upon release of the depressing Three, the compression spring within the pump arrangement urges the container 28 from the fully depressed position towards the rest position (i.e, in the direction denoted by arrow Y in the figure).

The container 28 can be moved through a number of depression. and release cycles in order to fill the container.
