Abstract
An insert for preventing the formation of skin on the surface of paint in a part used can comprises a flexible disc shaped member which is inserted into the can and contacts the side walls of the can and is pushed down into contact or close proximity to the surface of the paint. It may be in the form of a central body 4 of foam plastics material or cardboard sandwiched between two layers of flexible plastics 2,3 which are joined at the overlapping edges to form the can contacting flexible part. It preferably also has a handle means such as loop 5 for pulling it out. It is also usable for can or like containers of other products such as those in powder form. It may also be other shapes depending upon the shape of the container - eg square and may also be dished in shape with a raised central portion for gripping purposes.
Description
Improvements in or to Relating to Packaging Paint
The present invention primarily relates to a paint protector comprising a disc insert, for use with paint tins, which is adapted to prevent the formation of skin on the surface of paint in a partially filled tin of paint and other substances, and paint cans equipped with such a paint protector.
Both amateur and profession decorators are familiar with the formation of a skin on the surface of paint in partial filled cans of paint. This phenomena results in small pieces of solid paint being dispersed in the fluid paint in a can, when attempts are made to pierce, or remove, the skin to get at the underlying fluid paint.
When the paint is applied to a surface, these pieces of solid paint can be dispersed over the surface, with the fluid paint, spoiling the finish produced by the paint.
This problem is particularly marked with oil based paints such as gloss paints and undercoats.
The traditional way of dealing with this problem is to store partially filled cans of paint in an inverted position, so that any skin is formed on the bottom surface of the paint. This is far from an ideal solution, since paint can leak out from the inverted lid of a paint can and, if a paint can is not properly closed, the consequences of inverting the can are decidedly messy.
The present invention provides a particularly simple and cheap solution to this problem. A disc insert, or paint protector, is disposea on the surface of the paint in a partially filled can of paint. The disc insert prevents air contacting the surface of the paint and thus prevents formation of a skin on the surface of the paint. The disc insert may be provided with a tab, or handle, to assist in removal of the disc insert before use of the paint.
The paint protector of the present invention can be used inside a paint tin equipped with a conventional lid. or alternately can be used to provide a cover for the surface of paint contained in an open paint can, as used by painters to hold relatively small quantities of paint. The paint protector can be made in a variety of sizes, normally of circular periphery, but having peripheries of other shapes for square, or rectangular paint cans.
Although primarily intended for use with paint, the paint protector of the present invention can also be used with other substances, for example, other liquids with a tendency to form a skin on contact with air, or even powders which may react with atmospheric water vapour.
The paint protector, or can seal, of the present invention may be constructed of materials and in a form which adapt it for reuse.
According to a first aspect of the present invention, there is provided a paint protector, for prevention of the formation of a skin on the surface of paint, comprising a disc of material having a periphery approximately corresponding to the interior side wall of a paint can with which it is intended to be used and grip means for assisting in the removal of the paint protector from a can of paint.
The paint protector may have a generally circular periphery.
The disc of material may be a disc of flexible material.
The disc of material may be formed from a sandwich comprising an inner disc of foamed plastics encased between two sheets of plastics film, said two sheets of plastics film being bonded together.
Said grip means may comprise two plastics tab extensions formed in said two sheets of plastics film.
Alternatively the disc of material may be formed from a sandwich comprising an inner disc of cardboard encased between two sheets of plastics film, said two sheets of plastics film being bonded together.
Alternatively said grip means may comprise a loop of plastics tape attached to said disc of material.
Said inner disc may be adapted to bear indicia.
Alternatively said disc of material is a bowl shaped plastics disc with a raised land at the centre thereof, said raised land adapted to act as a grip means.
Said disc of material may be resilient and adapted to engage the inner wall of a paint can.
According to a second aspect of the present invention there is provided a paint can including a paint protector as described above.
According to a third aspect cf the present invention there is provided a method of inhibiting the formation of a skin on a paint surface in a partially filled can of paint, comprising placing a cover in intimate contact with the paint surface thereby isolating said paint surface from air.
Preferably said cover is substantially co-extensive with said paint surface.
Said cover may be buoyant.
Said cover may be flexible.
Said cover may be resilient.
Said cover may elastically engage a side wall of a paint can.
According to a fourth aspect of the present invention there is provided a can seal for inhibiting atmospheric access to the content of a partially filled can of liquid, or powder, or the like, comprising a disc of material having a periphery approximately corresponding to the interior side wall of said partially filled can and grip means for assisting in the removal of the can seal from the partially filled can.
The can seal may be adapted to be reusable.
Embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a plan view of a first embodiment of a
paint protector, according to the present
invention.
Figure 2 is a section through the paint protector
illustrated in Figure 1, along line A-A.
Figure 3 is a plan view of a second embodiment of
a paint protector, according to the present
invention.
Figure 4 is a section through the paint protector
illustrated in Figure 3, along line A-A.
Figure 5 is a plan view of a third embodiment of a
paint protector according to the present invention.
Figure 6 is a section through the paint protector
illustrated in Figure 5.
Figure 7 is a projection of the paint protector
illustrated in Figures 5 and 6.
Figure 8 illustrates a sectional view of a
partially filled paint can fitted with the paint
protector illustrated in Figures 5 to 7.
It will be understood that the term disc, as herein used, is intended to refer to a sheet of material having a periphery which corresponds to the internal shape of a paint can. The term disc is not intended to imply that the periphery thereof is necessarily circular, nor that the surface of the disc is necessarily planar.
Turning now to Figure 1 and 2, there is shown a paint protector, 1, having a generally circular periphery. The paint protector is constructed of a disc of material in the form of a sandwich having an inner cardboard disc 4, between two sheets of transparent flexible plastics, 2 and 3. The inner cardboard disc may be printed with indicia, 7, indicating, for example, the size of paint can with which the paint protector is intended for use. A loop of plastics tape 5, is attached to the disc by a rivet, or other fastening means 6, and acts as a grip to facilitate removal of the paint protector from a can of paint.
A second embodiment of the present invention is illustrated in Figures 3 and 4. The paint protector, 10, is constructed from a polystyrene foam disc, 14, sandwiched between two sheets of plastics film, 12 and 13. The plastics sheets have tabs 15, formed on their outer edges, which act as grip means to facilitate removal of the paint protector from a can of paint. The foamed polystyrene inner disc ensures that the paint protector will float on the surface of paint in a paint can.
Turning now to Figures 5 to 7, there is illustrated a further embodiment of the present invention. The paint protector is formed from a resilient sheet of plastics, 22, in a bowl shape. At the centre of the bowl a land, 21, is formed which can act as a grip means. The land may be circular, or shaped to assist gripping for removal of the paint protector from a paint can. Typically, the paint protector may be made by vacuum forming onto an appropriately shaped mould. The bowl shape of the paint protector facilitates contact between the periphery of the paint protector and the inner wall of a paint can. The edge of the paint protector is thus biased against the wall of a paint can and it is this contact which retains the paint protector in position within the paint can.
Figure 8 illustrates the paint protector of Figures 5 to 7 in position in a can of paint. The paint can is of conventional design, having generally cylindrical side walls, 31, and is partially filled wth paint, 32.
A lid, 33, is used to seal the can and engages the upper rim of the can with a force fit. The paint protector 20 is located on the surface of the paint 32, and engages the side walls, 31, of the paint can.
The embodiments of the invention described above use either a flexible disc, or a resilient disc.
However, a rigid disc may also be employed, although not as effective as the above described embodiments. Such a rigid disc may be manufactured from thin plywood, for example, which will float on the surface of the paint.
Unfortunately, in order to insert a paint protector made in the form of a rigid disc, the disc must be smaller than the diameter of the inner wall of the paint can to permit insertion and removal through the mouth of the paint can. This means that a little skin will form on the surface of the paint between the wall of the paint can and the edge of the paint protector.
Although it is an advantage if the edge of the paint protector is in contact with the walls of the paint can, it is not an essential feature of the present invention, provided the gap between the walls of the paint can and the paint protector is small.
The vast majority of paint cans are of circular cross-section, but some paint cans may be of square, or rectangular section. Thus in general the paint protector of the present invention will be in the form of a circular disc, but variants may be made to suit other shapes of can, e.g. as square, or rectangular discs.
Paint cans come in a variety of sizes, so paint protectors, according to the present invention will be produced in matching sizes. It is possible that paint protectors according to the present invention will be sold in packs containing a selection of sizes to suit a selection of different sizes of paint can. It may even be advantageous to produce paint protectors adapted for use with buckets in which paint is temporarily stored.
Many variations of the present invention will be immediately apparent to those skilled in the art. All such variations are intended to fall within the scope of the present invention.
