ABSTRACT:
FIELD OF THE INVENTION
This invention relates to pouring systems and more particularly to a disposable pourer for liquid containers such as paint cans.
BACKGROUND OF THE INVENTION
Pouring a liquid such as paint from a paint can often fouls the seal and creates spills and drips which require clean-up.
SUMMARY OF THE INVENTION
According to one aspect of the invention there is provided a pourer for a container comprising a strip of material of predetermined dimensions having an adhesive on at least a portion of one side, a cut-out portion in the central region of the strip having a part circular boundary and a backing sheet secured to the strip by he adhesive.
Preferably, the part-circular boundary of the cut-out portion is sized to suit a particular cylindrical container such as a paint pail or can and the remainder of the boundary of the cut-out portion is straight so that the cut-out portion forms a segment of a circle that is slightly smaller than the crosssection section of the paint pail or can.
The strip and backing sheet may be pre-assembled and the cut-out formed by die cutting the composite material.
According to another aspect of the invention there is provided a method of forming a pourer for a can comprising the steps of:
(i) providing a strip of material of predetermined dimensions having an adhesive on at least one portion of one side,
(ii) Placing the strip, the adhesive side down, on the open top of the can with the strip off-centre in relation to the can and with a central portion of the strip overlying the edge of the can and side portions of the strip extending outwardly of the can,
(iii) folding the side portion upwardly and inwardly so that a part thereof is adhered to the can and other parts thereof are adhered to the central portion of the strip, and
(iv) cutting away the portion of the strip inward of the rim to form the pourer.
In one form of the invention, the portion of the strip inwards of the rim is cut into tabs that are secured to the inner face of the rim and the can. The strip may be formed with or without a backing sheet and may be drawn from a roll or be preformed to suit a particular size of can. In the latter case, some or all of the strip destined to be inside the rim of the can may be removed.
