Abstract
An applicator is provided in which paint flow is facilitated utilising a grip pump bias to a paint distributor such as roller. The roller is configured within a head such that paint is appropriately distributed with limited leakage in order to allow easy operation for distributing paint upon a surface. The application also includes details of a number of refinements with respect to operation of the applicator at elevated or displaced positions, filling paint containers or canisters and providing greater paint flow control.
Claims75
An applicator for applying paint to a surface, the applicator including a body for paint, paint distribution means to distribute paint in use onto a surface by contact with that surface, the body including paint biasing means to bias, in use, the paint toward the distribution means, an operator in use holding the tool by the body and operating control means for control of the bias means and so the flow of paint distribution means, the applicator characterized in that the paint biasing means acts by applying incremental axial displacement of the paint.
(canceled)
A method of applying paint to a surface, the method comprising the use of an applicator, the method comprising providing paint to the applicator, holding the body, providing bias to the paint to drive that paint towards the distribution means and operating the control means to control a flow of paint to the paint distribution means, while moving the tool so that the paint distribution means contact and move across a surface to be painted, the method characterized in that the bias is provided by applying incremental axial displacement of the paint towards the distribution means.
(canceled)
Pouring apparatus for a paint can, the apparatus including a pouring member having an engaging means engageable in use with a portion of the rim of a paint can, the pouring member including a concave pouring surface, the pouring member arranged so that when in engagement with a paint can it has an upright position and the pouring surface directs any paint on the surface to run onto the surface of the paint in the can at a displaced position from the side of the can.

An applicator in which a roller is associated with an applicator head such that paint is distributed upon that roller using paint bias means, characterized in that and the head comprises paint traps either side of the roller to accommodate transient excess flows of paint due to any pulsed action of the paint bias means by provision of expansion cavities for those transient excess flows.
An applicator for applying paint to a surface, the applicator including paint biasing means to facilitate flow of paint to paint distribution means, the paint biasing means including a grip configured to progressively displace a plunger or piston in order to facilitate paint flow, the displacement range of that grip limited in order to similarly limit displacement of the piston and therefore rate of paint flow.
An applicator in which paint biasing means facilitates paint flow to paint distribution means wherein the paint bias means is associated with an extension handle which extends from the paint distribution means to the paint biasing means characterized in that the extension handle allows operation of the applicator at a displaced or elevated position whilst still allowing appropriate displaced operation of the paint biasing means by retention of the paint bias means with the paint distribution means all at one end of the handle and a push rod to operate that paint bias means extending from another end of the handle.
An applicator for applying paint to a surface, the applicator including paint distribution means within which an effective slot outlet is provided through which paint is presented to paint distribution means through use of paint biasing means, the paint being accommodated within a paint canister, characterized in that the paint canister has a cross-section of elongate dimensions such that the major axis of the canister is substantially aligned with the slot for better paint distribution through that slot by the paint biasing means.
A paint distribution insert for an applicator of paint, the insert comprising a groove network of varying cross-section and arranged whereby resistance to paint flow through the insert is varied across that insert for more even paint distribution across an outlet from an initial single inlet position of substantially narrower width.
An applicator for applying paint to a surface wherein that paint is distributed by a roller and the roller is secured through a cam whereby the roller rotates with a rollover rotation past a paint outlet characterized in that the rollover rotation is eccentric with differing gap widths between a roller surface and the outlet on one side on the other side in the roller rotation direction.
