Description

SPRAYER
BACKGROUND OF THE INVENTION
1. Field of the Invention
The field of the invention is apparatus and components for spraying.
2. Technical Background
Spraying is a common requirement. Sprays are ubiquitous in modern consumer life, and find applications such as in cans of spray paint, sprays of dc-jeer for car windscreens, and perfume sprays. Although sprays which are refillable are known, the integral spray nozzle may become dirty, clogged or damaged from repeated use.
Known refillable sprays can only be refilled with a same product. In known refillable sprays, the product container is typically integral not modular and mixing products would also cause contamination and nozzle cloing.
3. Discussion of Related Art US207957 describes a spray which includes a liquid container. The liquid container may he removed and refilled, thereby prolonging spray product life.
In LTS4,t47,284 there is described an aerosol dispenser in which the material to he expelled is carried within a container in communication with a spray nozzle. An air compressor carried by the container supplies compressed air to the container to pressurize the material. The compressor is operated by the normal vertical shaking of the assembly. The compressor may be carried within the container or attached thereto during use. In one embodiment the container may he refilled. In a second embodiment the container is separable from the compressor and may he discarded after use. Prior art Figure 14 shows an aerosol dispenser described in US4,l47,284. In Fig. 14, 10 indicates an aerosol dispenser having a reservoir Il. A dispensing nozzle 12 is carried at die top of the reservoir and an air compressing pump module 13 is removably secured to the
I
reservoir. As shown in FTC. 14-, a quantity of liquid 14 or other material to he dispensed is placed within the reservoir 11. One portion of the reservoir wall 15 is flattened to provide a hearing surface to receive the air compressing pump module 13. The flattened wall 15 is also provided with an elastomeric seal 16. The air compressing pump module consists of a container 17 having a needle-like member 18 projecting therefrom. The container 17 is also preferably made with a curved wall 19 and a flattened wall 20 which is complementary to the wall 15 of the reservoir. The upper portion of the container 17 is formed with a series of extending latches 21 which are adapted to engage recesses 22 adjacent the flattened wall 15 of the reservoir 11. A flange member 23 is carried at the bottom of the container 17 and is secured to a head 24 at the bottom thereof.
A pump 26 within the air compressing pump module includes a bellows 27 secured at one end to a wall 28 carried within and adjacent to the bottom of the container 17. A small valve 29 is secured at one end to the bottom 30 of the container 17 and to the wail 28 at its other end. The valve 29 is in communication with ambient atmosphere through an opening 35 in the container bottom 30. A second opening 36 in the wall 28 places the valve 29 in communication with the interior of the bellows 27.
A second vaive 31 which may be a flap valve is secured at one end to the free end of the bellows 27 and at its other end to a weight 32. The weight 32 is slidably carried within the container 17 and is axially bored as indicated at 33. The valve 31 permits air to pass from the bellows 27 into the bore 33.
As shown in 11G. 14, a flexible tube 34 is carried within the bore 33 and cemented or otienvise secured thereto. The opposite end of tube 34 is connected to the nozzle 18. As the air compressing module is swung downwardly, the inertia of the weight 32 will cause the bellows 27 to he expanded axially. Air will he drawn into the bellows through the valve 29. When the downward motion of the container 17 stops and an upward direction is imparted to it, as in vertical shaking, the weight 32 will he forced downwardly against the bellows thereby compressing it. The air in the bellows will be forced through the valve 31 up the flexible tube 34 and out of the nozzle 18.
In Fig. 14, the pressure source feeds in to an air gap above die product to be dispensed.
With regard to the disadvantages of attaching the module horizontally in Fig. [4, when the module is detached it could vent any unused pressure within it, presumably around the hole where it is attached to the pump mechanism. The arrangement of the connection suggests this could possihy occur upwards, in the direction of the user's eyes, which is hazardous. LTS4,147,284 mentions clips which seem either to flex and click into place or to he engaged separate'y, after the location of their module against the pump assembly.
The first of these possibilities could he tricky to remove and have longevity issues; the second is complicated and tiddly. Ii:)

Also, the female thread attaching the module to the piston may have a catch to hold the module in place, for example to pop into a hole on the piston thread to hold it tight and pre\;ent it from spinning when the module is again twisted to lock it into place on the mechanism.
In an example (eg. Fig. 15), there is provided a module containing a product in liquid or powder form attached to the tubular piston of a pump mechanism, by \vay of a male thread on the piston and a reciprocal female thread on the module. Using the module to push and pull the piston in and out of a reciprocal circular bore in the body of die pump mechanism, air is compressed via a valve at the bottom of the bore and stored in the chamber of the pump mechanism.
On fully depressing the piston, the module can be locked into place on the pump mechanism by way of a ma]e thread on the pump mechanism and a second reciprocal female thread on the module. Thus secured, a valve at the top of the pump mechanism is opened by depressing a button and the pushrod attached to it, which runs through the product module to its base. An extension on the side of the pushrod simultaneously opens a valve in the vent channel of the product module.
On opening the valve at the top of the pump mechanism, the compressed air within it is vented into the pi-oduct module, via a channel with an outlet, suitably filtered to allow the flow of air into the module, hut to prevent the flow of any product hack the other way and into the channel.
Thus pressurised, the product is forced into a vent channel, by way of a pick-up point at the base of the module product chamber.

Compressed air is vented frotii the pump mechanism through a channel which passes over a hole in a chamber inside the head attachment, causing a vacuum in the chamber. The exiting air continues and is routed to the rear of (or to a different part of) the attachment and diffused. The resulting temporary vacuum in the head attachment chamber causes it to dra\v in air through a small tube or straw which projects from it. The head attachment chamber could then he accessed, perhaps by a pop-off lid, to empty it of any debris collected. The straw could have a fine brush on the end. Notes
In the above examples, where a sliding cover is indicated i.e. one attached to the piston, other configurations are possible eg. the piston could be an exposed plunger, or even he part of the product module, as would he appreciated by those skilled in the art.
The air storage chanther in the base unit could be formed around a cylinder which would accept a piston attached to a product module and inserted from above. A two-stage pump could be provided.
An arrangement is possible in which a piston within the pressurisation dexice attaches directly to the module, which then also acts as a handle.
