The present invention relates to the field of paint storage containers. More particularly, this invention relates to a paint storage apparatus that is divided into separate chambers and comprises a complimentary lid with multiple tapered holes aligned with the separate chambers allowing storage of paint in the separate chambers.
Paint storage containers such as paint cups are well known and have been used by painters for many years. Painters use paint cups by dipping their paintbrushes into the cups, and then applying the paint from the cups to an accompanying surface. A painter may use a paint cup by itself, or in conjunction with other paint cups, which normally contain other paint colors. Paint cups may be placed near a painter's surface, such as on or near a painter's easel, for easy access and use by the painter.
Paint cups may be made of a variety of materials, including plastic. Paint cups also may exist in various sizes, depending on the amount of paint that the painter needs to utilize, and various shapes such as cylindrical or square. For example, cylindrical/rounded cups are used for ease of fit into easels and cup holders.
Currently, paint cups contain a single chamber space designed to hold only one color of paint. In other words, current paint cups are unable to separately hold more than one color of paint at the same time. This has many disadvantages: multiple cups are required by a painter who is using more than one color or type of paint; and more space is required at or near a paint easel for storing multiple paint cups. Further, current paint cup lids contain only one hole through which the painter may dip his/her paintbrush.
A divided paint storage apparatus is disclosed. The preferred apparatus comprises a container, a lid, and a cap. The container comprises integrally formed walls defining a main chamber body portion with an open upper end. The container is divided into a plurality of chambers. It should be understood that the terms compartments, cavities, chambers, or chamber regions are used interchangeably. One or more inner walls divide the main chamber of the container into the plurality of chambers. The plurality of chambers are preferably defined by the enclosed space between the one or more inner walls and the main chamber and are configured for receiving and retaining paint in separate and sealed chambers.
The lid of the current invention preferably matches the container and comprises a planar surface with a top, a bottom, and a plurality of orifices. The bottom of the planar surface preferably comprises one or more depending grooves configured to cooperatively engage with the one or more inner walls and align the plurality of orifices over the plurality of chambers, with one of the plurality of orifices over each of the plurality of chambers.
In one embodiment, this may be achieved by using a guiding means on the lid that is configured to mate with the container. Further, the guiding means is also affixed to the container in a manner that ensures that the plurality of orifices in the lid are equally aligned over the respective chambers of the container.
In alternate embodiments, the lid and container are in a shape which does not require use of depending grooves or a guiding means to ensure alignment of the plurality of orifices with the plurality of chambers. For example, a square shaped lid and matching container ensure an aligned and securely divided paint storage apparatus configuration.
In yet another embodiment, one or more guiding means couple with one or more inner walls through an annular locking structure that frictionally engages so as to create a positive seal. Alternately, the guiding means may comprise a channel configured to couple with a raised inner wall of the container so as to create a positive seal between the lid and the container.
Regardless of the means used to mate the lid and the container, when the lid and the container are mated, the plurality of chambers in the container are sealed such that the paint cannot be interchanged between the chambers. Further, regardless of the shape of the container or lid, the plurality of orifices preferably are in a tapered configuration. This allows paintbrushes to be guided into each separate chamber and also provides the user with a surface to rub off excess paint from the paint brush.
In the preferred embodiment, the apparatus further comprises a cap configured to detachably couple to the lid and prevent spillage and spoilage of paint stored within the container. The cap preferably provides an air tight seal when coupled to the lid to prevent the spillage and spoilage of paint stored in the cup. In addition, the lid and cap preferably each further comprise tabs configured to facilitate removal of the lid from the container. Alternatively, the lid is coupled to the cap by a hinge.
The container is preferably substantially cylindrical and is uniformly formed from a homogenous material. The homogenous material preferably comprises a polymer resin, however, the homogenous material may also comprise polypropylene or a liquid impervious plastic material in alternate embodiments. In alternate embodiments, the shape of the container and matching lid and cap may include, but are not limited to, circular, square, triangular, angular, or star shaped. In the preferred container, the container is further configured such that the diameter of the top of the container is greater than the maximum diameter of the bottom of the container. In alternate embodiments, the bottom of the divided paint storage apparatus further comprises an annular ring configured to support the apparatus on a surface.
In addition to the embodiments disclosed above, a method of forming a divided paint cup is disclosed. Specifically, the method comprises first thermoforming plastic into one or more dividing walls with a generally parallel matrix configured into a generally cylindrical shape. Next, plastic is thermoformed around the dividing walls and into a generally cylindrical body portion. The body portion has an open upper end and a rim extending radially outwardly from the perimeter of the open end of the body portion. The method disclosed may further comprise the step of thermoforming plastic into a generally cylindrical lid having a plurality of orifices and a plurality of grooves configured to mate with the plurality of dividing walls.
In short, the divided paint storage apparatus is preferably a round cylinder made of clear plastic and is configured to hold paint in separate chambers. These chambers are preferably, but not necessarily, equal in size. These different paint chambers, and paints contained therein, are easily accessible for use by a painter. The separate and sealed chambers are defined by interior walls of the apparatus and prevent any interchange between the paints from each separate chamber.

Specifically, the container 230 of the apparatus 200 comprises integrally formed walls which define a body portion main chamber 232 with an open upper end. The container 230 is divided into a plurality of cavities 245. Inner walls 255 divide the main chamber 232 of the container 230 into the plurality of cavities 245. The plurality of cavities 245 are preferably defined by the enclosed space between the inner walls 255 and the main chamber 232 and are configured for receiving and retaining paint in the separate and sealed chambers of the plurality of cavities 245.
The lid 220 of the current invention preferably matches the container 230 and comprises a planar surface with a top (not shown), a bottom 225, and a plurality of orifices 235. The bottom 225 of the lid 220 preferably comprises a depending groove 265 configured to cooperatively engage with the inner walls 255 of the container 230 and align the plurality of orifices 235 over the plurality of cavities 245, with one of the plurality of orifices 235 over each of the plurality of cavities 245. In other words, when the lid 220 and the container 230 are mated, the plurality of cavities 245 in the container 230 are sealed such that paint 265 cannot be interchanged between the cavities 245.
In one embodiment, the lid 220 is coupled with the container 230 via a guiding means (not shown) on the lid 220 that is configured to mate with the container 230. Similar to the depending groove 265 coupling with the inner walls 255, the guiding means (not shown) also affixes to the container 230 in a manner that ensures that the plurality of orifices 235 in the lid 220 are equally aligned over the respective plurality of cavities 245 of the container 230.
In yet another embodiment, a plurality of depending grooves (similar to the depending grooves 245) couple with multiple inner walls (similar to the inner walls 255) through an annular locking structure (not shown) that frictionally engages so as to create a positive seal.
Regardless of the means used to mate the lid and the container, when the lid and the container are mated, the plurality of chambers in the container are sealed such that the paint cannot be interchanged between the chambers. Further, regardless of the shape of the container or lid, the plurality of orifices preferably are in a tapered configuration. This allows paintbrushes to be guided into each separate compartment and also provides the user with a surface to rub off excess paint from the paint brush.
In the preferred embodiment, the apparatus further comprises a cap 210 configured to detachably couple to the lid 220 and prevent spillage and spoilage of paint 285 stored within the container 230. The cap 210 preferably provides an airtight seal when coupled to the lid 220 to prevent the spillage and spoilage of paint stored in the paint cup. This allows the user to retain the paint within the paint cup without pouring the paint back into the original container, which could contaminate the rest of the paint by introducing bacteria from the painting process. In addition, the cap 210 and the lid 220 preferably each further comprise tabs 275 and 275′, respectively, configured to facilitate removal of the lid 220 from the container 230 and to facilitate removal of the cap 210 from the lid 220. Alternatively, the lid is coupled to the cap by a hinge.
The container is preferably substantially cylindrical and is uniformly formed from a homogenous material. The homogenous material preferably comprises a polymer resin, however, the homogenous material may also comprise polypropylene or a liquid impervious plastic material in alternate embodiments. In alternate embodiments, as shown in
The apparatus 300 further comprises a cap 330 configured to detachably couple to the lid 320 and prevent spillage and spoilage of paint 385 stored within the plurality of separate chambers 313.
