Description
WO 2005/087614 PCT/AU2005/000327 1 DISPENSING DEVICE TECHNICAL FIELD 5 The present invention is directed to a dispensing device and, in particular, to a dispensing device for separately storing, dispensing and applying proportional amounts of two substances. The invention has been developed primarily for dispensing glue or adhesive in the form of an epoxy and a hardener and will be described with reference to this application. 10 However, it will be appreciated that the invention is not limited to this particular field of use. BACKGROUND OF THE INVENTION Many devices are known which are useful for dispensing proportional amounts of two 15 materials, typically epoxy and hardeners, kept separately prior to dispensing. Commonly, prior art devices comprise two collapsible tubes along with a means for holding the two tubes together. While the use of two tubes held together to dispense an epoxy and a hardener would appear to be effective, there are certain disadvantages. The use of a common sleeve or yoke to hold the devices together can interfere with the evacuation of the tubes. In addition, it is 20 difficult to ensure that the proportional amounts of the substances within the tubes are dispensed. This is particularly the case when dispensing small amounts of the substances. Prior art devices are commonly provided for larger scale applications, meaning the tubes or containers holding the epoxy and hardener must be resealed after use. As a result blockage of the tube or dispensing device is common. This can render the glue unusable or difficult to 25 apply in a consistent manner. There is therefore a need for a device for separating and dispensing epoxy and hardeners in a single use pack. The device generally requires two hands for dispensing the contents. The distance between the nozzles of the two tubes can make proper mixing of the two substances difficult. 30 -2 Prior art devices also include more complicated dispensing systems utilising air pressure or a displacement pump to remove epoxy and hardener from separate chambers. While many of these systems are effective, these machines are not intended for use in small applications and require significant outlay of money and investment of space and time. 5 It would be advantageous to provide a dispensing device which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or to at least provide an alternative. 10 SUMMARY OF THE INVENTION In accordance with the invention, there is provided a one-use dispensing device having a web provided with flexible receptacles for storing two substances, the substances being stored separately and dispensed together, wherein the receptacles comprise: 15 a flat nozzle portion that is tapered toward an end portion thereof; and an outlet portion bound to the flat nozzle portion by a tearable edge portion form on the end portion of the nozzle portion, the dispensing device further comprising: a straight line of fold extending over the device between the receptacles to allow 20 the web to be folded to superpose the receptacles; tear lines formed on the web to allow the respective outlet portions to be torn at the edge portion, wherein the device is constructed to be folded about the straight line of fold, so that the outlet portions can be torn by the tear lines at the edge portions, and the receptacles are 25 pressed to allow discharge of the substances from the edge portions to dispense, mix and apply the substances.

BRIEF DESCRIPTION OF THE DRAWING 5 A preferred embodiment of the invention will now be described, by way of example only, with reference to the accompanying figure in which: FIG 1 is a plan view of a dispensing device in accordance with a preferred embodiment of the 10 present invention. FIG 2 is an elevation view of the dispensing device shown in Fig. 1. FIG 3 is a perspective view of the dispensing device of Fig. 1 in a partially folded configuration. FIG 4 is a perspective view of the dispensing device 1 of Fig 1, in a folded configuration and 15 torn open. FIG 5 is a perspective view of the dispensing device as a user squeezes it. BEST MODE OF CARRYING OUT THE INVENTION 20 Referring to Figs. 1 - 5, there is shown an embodiment of a dispensing device for separately storing two substances in accordance with the present invention. The device is adapted to dispense, mix and apply proportional amounts of the substances. The dispensing device 1 comprises a substantially flat thin flexible web 2. The web 2 includes a longitudinal axis 3 which is preferably scored or vacuum formed to enable a user to easily fold the dispensing 25 device 1 about longitudinal axis 3. Two receptacles 4 and 4' are disposed about longitudinal axis 3. The receptacles 4 and 4' are disposed such that the receptacle 4 on one side of the longitudinal axis 3 is a transposed mirror image of the receptacle 4' on the other side of the longitudinal axis 3. 30 WO 2005/087614 PCT/AU2005/000327 5 The receptacles 4 and 4' each include an outlet 5. The outlet 5 is nozzle shaped to allow a substance contained within the receptacle 4 to be easily evacuated from the receptacle 4. The outlet 5 is positioned on or adjacent the side edge of the web 2, distal from the longitudinal axis 3. It can be seen that when folded, the receptacle 4 on one side of the longitudinal axis 3 5 is substantially aligned with the receptacle 4' on the other side of the longitudinal axis 3. The web 2 and receptacles 4 and 4' may be integral to one another or may be composed of separate materials and sealed or otherwise affixed to one another. The materials are flexible to allow a substance contained within receptacle 4 to be squeezed through outlet 5. The web may 10 be composed of foil or polyethylene, polypropylene, polyvinyl chloride, polyvinyl acetate or foil coated with one of the plastics, specifically polypropylene. The receptacles 4 and 4' may similarly be composed of a foil or polyethylene, polypropylene, polyvinyl chloride, polyvinyl acetate or foil coated with on of the plastics, specifically polypropylene. The web 2 and receptacles 4 and 4' may comprise one or more laminae. The laminae may be composed of 15 foil or polyethylene, polypropylene, polyvinyl chloride, polyvinyl acetate or foil coated with on of the plastics, specifically polypropylene or each lamina may be composed of a separate material. The laminae are then sealed together to form the receptacles 4 and 4'. The receptacles 4 and 4' further include indicia or markings 6 to indicate where a user is to 20 place his or her thumb and forefinger in order to evacuate a substance contained within receptacles 4 and 4' through outlet 5. The indicia 6 can be incorporated into the shape of the receptacles 4 and 4' or can be painted or printed thereon. It can be seen that these indicia 6 allow for a substantially complete evacuation of receptacle 4 through outlet 5. Moreover, it can be seen that the indicia 6 allow for easy one-handed use of the dispensing device 1. 25 Outlet 5 may include a weakened point or region (not illustrated). In use the substances contained within the two receptacles 4 and 4' will burst through the weakened region upon a user squeezing receptacle 4. Alternately, web 2 and outlet 5 can incorporate a scored or vacuum formed tear line 7. Tear line 7 may be double die-cut The tear line 7 leads through 30 the weakest point of outlet 5. It can be seen in Figs. 4 and 5 that upon a user cutting or tearing WO 2005/087614 PCT/AU2005/000327 6 along tear line 7, the seal on outlet 5 would be opened allowing the substances contained within the receptacles 4 to be evacuated by squeezing. The substances contained within the two receptacles 4 and 4' in this embodiment may be an 5 epoxy and a hardener, however any preferred substances can be used. In use it is important that proportional amounts of these substances be applied to a surface (not illustrated). In use the epoxy and hardener can be in the proportions 1:1, 1:2, 1:3, 1:4, 1:100 or any suitable proportions. The receptacles 4 and 4' can be molded to any predetermined size. When the receptacles 4 and 4' are of differing sizes the outlets 5 are still substantially aligned. It can be 10 seen that in the present invention the proportion of the substances used is defined by the size of the receptacles 4. In other embodiments the substances contained within the two receptacles 4 and 4' may be foodstuffs, pharmaceuticals, medical or dental products, beauty aids or any liquid, paste or gel 15 substances designed for separate storage and simultaneous application. In use the receptacles 4 and 4' may be independently evacuated such that one or other of the two substances contained therein is dispensed. The dispensing device 1 is designed to be used once and then disposed of. The dispensing 20 device 1 can be sold in single application packs which comprise two receptacles 4 or in multiple application packs (not illustrated) where each pair of receptacles 4 corresponds to one application. The dispensing device 1 may preferably have dimensions of approximately 60mm by 45 mm. 25 The receptacles 4 and 4' may preferably be approximately 7.5 mm in radius at their base (not illustrated) and approximately 5mm in radius at their top (not illustrated). The outlets 5 may preferably taper to an end approximately 15 mm from the centre of the receptacles 4 and 4'. In this case the receptacles 4 and 4' contain between approximately 1 ml and approximately 5 ml of substance. However the receptacles 4 and 4' can be molded to contain any preferable 30 volume of substance and may contain different amounts from one another.
-7 The dispensing device 1 is adapted to be folded and manipulated by a user in a one handed operation such that the outlets 5 are easily aligned and the substances contained within receptacles 4 and 4' are simultaneously dispensed, mixed and proportionally applied to a surface. In use the receptacles 4 and 4' extend outwardly once folded. In 5 use the flat edges 8 of outlets 5 assist in mixing the two substances when they come into contact after application to the surface (not illustrated). The foregoing describes only a preferred embodiment of the present invention and modifications, obvious to those skilled in the art, may be made thereto without 10 departing from the scope of the present invention. The term "comprising" (and its grammatical variations) as used herein is used in the inclusive sense of "having" or "including" and not in the exclusive sense "consisting only of'. 15 It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute an admission that the publication forms a part of the common general knowledge in the art, in Australia or any other country. 2004265.1 (GHMatters) P62135 AU
