Abstract

The invention relates to a dispenser for a meltable material, such as a hot melt adhesive, which is adapted to be hand held and heated by a flame from a cigarette lighter. The dispenser comprises a barrel 1 adapted to receive the meltable material in a longitudinal bore 2. The barrel is provided with a nozzle 4 adapted to be heated by the flame. One end 7 of a resilient substantially V-shaped actuator 6 is mounted on the barrel and the free end 9 of the actuator engages with a longitudinal slot in the barrel. Application of pressure to the actuator against the resilience thereof urges meltable material towards the nozzle. <IMAGE>

Description

SPECIFICATION Dispenser This invention relates to a dispenser for meltable materials.
Many materials which are present initially in a solid form need to be heated, for example, to above their melting point, prior to being dispensed. The most commonly used such materials are hot melt adhesives, sealants and fillers. At present such materials are generally dispensed by means of a dispenser which includes electric heating means.
Such dispensers are expensive and this limits the use of hot melt adhesives in the domestic environment.
An alternative form of dispenser is proposed in British patent 2,031,306 B. This takes the form of, in effect, a combination of a dispenser for hot melt adhesive and a cigarette lighter, the dispenser being heated by the flame from the cigarette lighter.
The present invention relates to a particularly convenient form of hand held dispenser for meltable materials and is also intended to be heated by a flame.
The present invention provides a dispenser for a material which needs to be heated prior to being dispensed, the said dispenser comprising a barrel adapted to receive the meltable material and provided with a longitudinal slot, a nozzle at one end' of the barrel adapted to be heated by a flame to melt the meltable material and to dispense melted material, a handle mounted on the barrel and a resiliently mounted trigger, a portion of which is capable of engaging with the inside of the barrel by means of the longitudinal slot, so that application of pressure to the trigger against the resilient mounting thereof urges meltable material towards the nozzle.
According to one embodiment, the handle and trigger take the form of a substantially V-shaped member, at least the vertex of which is made of resilient material, one end of the member being attached to the barrel towards the nozzle end thereof and the other end being capable of engaging the inside of the barrel by means of the slot.
The invention will now be described in more detail with reference to the accompanying drawings, in which: Figure lisa side view of one embodiment of a dispenser according to the invention, Figure 2 is a similar view of the same embodiment, partly in section, and Figure 3 is a rear view of the same embodiment.
The dispenser shown in the drawings comprises a barrel 1 which is provided with a longitudinal bore 2.
The bore is open at one end 3 of the barrel and connects with a nozzle 4 at the other end. The nozzle is provided with a corresponding bore 11 and an orifice 12 of reduced cross-section relative to the bore. An insulating ring 5 is provided between the barrel and the nozzle. A substantially V-shaped actuator 6, which performs the functions of a handle and a trigger, is mounted on the barrel at 7. The actuator is made of a resilient material and the free end is provided with a shoulder 8 and a portion of reduced width (finger) 9. The finger 9 engages in a slot 10 (figure 3) in the bottom of the barrel.
In use, a meltable material in the form of a stick of appropriate size is placed in the bore 2 through the open end 3 so that it extends partly into the nozzle and the finger 9 is engaged with the slot 10. The stick of meltable material is not shown in the drawings. The nozzle is heated by a flame, e.g. from a cigarette lighter, and this causes the meltable material in the nozzle to melt so that it can be dispensed through the orifice 12. The dispenser is held in the hand by means of the actuator 6 and pressure on the free arm of the actuator against the resilience thereof causes the finger 9 to urge the meltable material towards the nozzle. As the meltable material is used up, the free arm of the actuator can move closer to the arm which is mounted on the barrel and this free arm is shown by dashed lines in figure 1 in an intermediate position.
When the actuator is released it returns to its initial position as shown in figures 1 and 2.
The nozzle 4 is intended to be heated with a flame and functions as a heat sink and should thus be made of a material having a good heat conductivity, e.g. aluminium or an aluminium based alloy. The nozzle can be provided with ribs as shown in the drawings to assist transfer of heat from the flame. If it is constructed of aluminium or an aluminium alloy, the nozzle can be anodised, preferably with a black finish to mask the effect of soot from the flame. The remainder of the dispenser is protected from heat from the nozzle by means of the insulating ring 5. This ring should be constructed of a material which is a poor heat conductor and is resistant to elevated temperature (flame retardant).
Examples of suitable materials are thermosetting plastics materials such as phenolic and melamine resins.
The barrel is preferably made of a flame retardant thermopiastics material and examples of suitable materials include filled and unfilled polyesters, nylon and ABS. The actuator of the dispenser shown in the drawings should be made of a material which can stand up to the stresses involved in the movement of the free arm relative to the fixed arm (so called "engineering plastics"). Subject to this requirement, any of the thermoplastic materials referred to above can be used. Further possible materials for the actuator include polyacetals and polysulphones. Preferably the actuator should be flame retardant but this is not essential and the actuator could be made of a non-flame retardant polypropylene.
The various parts of the dispenser can be moulded from the appropriate material and assembled in conventional manner. One possible modification in the construction from that shown in the drawings is that the actuator could be made in two or more parts to that only that part which is actually subject to flexing is made of "engineering plastics" with the remainder made of a cheaper thermoplastic plastics material.
