Title: Support clip-brush holder and brush keeper assembly for storing paint brushes

Description:
TECHNICAL FIELD 
     The present disclosure relates generally to support clips, brush holders and brush keepers for storing paint brushes between uses. 
     BACKGROUND 
     One of the most common challenges faced by individuals who use a paint brush to apply paint from a paint container, such as a paint can or a paint bucket, is placement of the paint brush at rest during periods when painting is interrupted. Typically, the individual will place the paint brush in or on the container, either oriented vertically with the bristles of the brush resting against the bottom of the container, or oriented horizontally with the bristles resting against the top of the container. It is known to employ paint brush holders for this purpose, but generally such brush holders require that the holder, the brush, or both extend to the exterior of the container. 
     It is also known to use brush keepers to cover paint brushes for wet storage of the paint brushes when not in use. Typically, brush keepers are specialized devices that require transferring the brush to the brush keeper rather than storing the brush in its normal work environment. 
     SUMMARY 
     What is needed are improved methods and apparatus for holding and storing paint brushes during periods when painting is interrupted. What is needed are simplified, time saving methods for storing paint brushes during periods between uses. What is needed are methods and apparatus for holding paint brushes that use interior space within paint containers for compact, space-saving storage. What is needed are environmentally friendly methods for storing paint brushes that make use of materials on hand.

     DETAILED DESCRIPTION 
     The present disclosure is here described in detail with reference to embodiments illustrated in the drawings which form a part here. Other embodiments may be used and/or other changes may be made without departing from the spirit or scope of the present disclosure. The illustrative embodiments described in the detailed description are not meant to be limiting of the subject matter presented here. 
     Reference will now be made to the exemplary embodiments illustrated in the drawings, and specific language will be used here to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Alterations and further modifications of the inventive features illustrated here, and additional applications of the principles of the inventions as illustrated here, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention. 
     When using containers of paint and paint brushes, professional painters and other users also often employ painting accessories to facilitate painting. One type of painting accessory is brush holders which can be used for organizing and storing paint brushes. Another type of painting accessory is brush keepers which cover paint brushes when not in use and allow for wet storage of paint brushes. Using brush keepers, when painters take a break they may not have to wash their brushes. 
     Disclosed embodiments of a support clip/brush holder assembly and a brush keeper kit provide various advantages over conventional painting accessories. The support clip/brush holder assembly of the disclosure can be easily mounted to the rim and inner sidewall surface of a typical paint container to be securely supported by these container structures. The support clip/brush holder assembly of the disclosure retains brushes within an interior space of a paint can or of an interior space defined by multiple paint cans. Support clip/brush holder assemblies of the disclosure can hold one or more paint brushes suspended in a vertical orientation within a paint container. Unlike conventional brush clips and brush holders, no portion of the support clip/brush holder assembly attaches to the exterior of the container or extends beyond the interior space defined by one or more paint can(s). Due to these characteristics, the support clip/brush holder assembly may be employed as a component of the brush keeper kit of the present disclosure. 
     In disclosed embodiments, the support clip is a flat member that includes a container engagement section having a plurality of edge surfaces configured to mount to an upper interior portion of a paint container, and that further includes a brush holder support section. The brush holder support section of the support clip carries a brush holder within the interior of the paint container. The brush holder is configured to hold a paint brush suspended from the brush holder. In the present disclosure, brush holder and paint brush holder refer to a member configured for holding a paint brush. 
     The upper interior portion of commercial paint containers has a fairly standard configuration across a range of sizes, types, and constituent materials of paint cans and buckets. An annular rim extends inwardly from the upper end of the container’s sidewall. The support clip is configured to engage an inner edge of the rim and an inner sidewall surface of the container just below the rim, and may further engage a lower surface of the rim. A container engagement section of the support clip includes various edge surfaces configured to engage these container surfaces. 
     The edge surfaces of the container engagement section of the support clip include a first segment configured to engage an inner sidewall surface of the container extending below the rim, and a second segment configured to engage an inner edge of the container rim. The edge surfaces may further include an intermediate segment extending between the first segment and the second segment, wherein the intermediate segment is configured to engage a lower surface of the rim. In an embodiment, the second segment includes a hook configured to fit over an upper lip at the inner edge of the rim, and a portion of the second segment is configured to engage an inner edge surface at the inner edge of the rim. In an embodiment, the first segment and the intermediate segment form a convex angular member configured to fit into a recess at a lower surface of the rim adjacent the sidewall. In an embodiment, the first segment includes a protrusion configured to abut against the inner sidewall surface of the container in order to adjust orientation of the support clip. In an embodiment, the support clip snaps into place and is frictionally retained by the rim and the sidewall. 
     The brush keeper kit of the disclosure enables painters to use paint containers as brush keeper parts to cover paint brushes when not in use for wet storage of paint brushes. The brush keeper kit allows a painter to store one or more paint brushes in an interior space defined by first and second paint containers stacked in an open end-to-end configuration with lids of both containers removed. A first, lower paint container is placed in its normal orientation, and a second, upper paint container is placed over the first container in an inverted configuration with the open face of the upper container aligned with the open face of the lower container. The brush keeper kit includes a paint container adapter that fits over the periphery of the open upper end of the lower paint container that faces upwardly and that fits under the periphery of the open end of the upper paint container that is inverted to face downwardly. The paint container adapter connects the upper and lower containers in a stacked configuration. 
     In an environmentally-friendly arrangement, the brush keeper kit of the disclosure enables painters to employ materials at hand such as used paint cans or paint buckets. The brush keeper kit of the disclosure permits storage of paint brushes in paint containers between painting sessions, thereby saving time. 
     The brush keeper kit of the disclosure may include a brush holder configured to hold one or more paint brushes within the brush keeper interior space. In an embodiment, the brush holder is secured to the lower paint container and holds a paint brush suspended below the brush holder. In an embodiment, the brush holder is secured to an inner sidewall surface and rim of the lower container. In an embodiment, the brush keeper kit includes the support clip/brush holder assembly of the disclosure. 
     The paint container adaptor together with the upper and lower paint containers define an interior space for wet storage of one or more paint brushes. The present disclosure sometimes uses the term “brush keeper interior space” to describe the interior regions of upper and lower paint containers stacked in an open end-to-end configuration with the paint container adapter of the disclosure. In a use case of wet storage using the brush keeper kit of the disclosure, one or more paint brushes may be stored with bristles at least partially immersed in liquid stored in the lower paint container, such as in paint or solvent. In a use case of wet storage using the brush keeper kit of the disclosure, one or more paint brushes may be stored with bristles suspended above liquid stored in the lower paint container, such as in volatile vapors within the brush keeper interior space. The interface between paint container adapter and upper and lower paint containers serves as a barrier to evaporation of volatile materials such as aqueous or non-aqueous paints and solvents. The paint container adapter of the disclosure prevents or limits loss of volatile materials during a time interval of wet storage 
     In typical manufacture of a paint container  610  (also referred to herein as a paint can or paint bucket) as seen in  FIG.  6 B , the container includes a sidewall  614  extending from a base  612  to a top edge  616 . As seen in  FIG.  6 C , at the top edge  682  of the sidewall the container includes a bead that extends around the periphery of the upper end of the container. The container includes a radially inwardly extending annular element  680  secured to the top  682  of the sidewall  614  of the container. In the present disclosure, this annular element is generally referred to as the rim. The rim  680  extends radially inwardly from a major (outer) diameter to a minor (inner) diameter. In the present disclosure, structure of the rim at the minor (inner) diameter is sometimes referred to as the inner edge of the rim. An upper portion of the inner edge  685  may include a lip  684 . A side portion of the inner edge  685  may define an inner edge surface  688  of the rim  680 . 
     The rim  680  may include a seaming panel for attachment to a side wall of the container by mechanical crimping or rolled seaming to a can flange adjacent the outer edge of the rim. An upper surface of the rim may define a ring groove  684  extending in a circular path entirely around the ring element between the major and minor diameters of the ring. A lower surface  676  of the rim  680  extends from a junction to sidewall surface  670  of the container to the inner edge  685  of the rim. The rim may include a recess  674  adjacent the junction of the rim  680  to the inner sidewall surface  670 . 
     An area at the top of the container that is not covered by the rim  680  defines a circular container opening  690 , providing access to interior space of the container. Typically, a paint container lid (not shown in the drawings) is friction fit onto the rim  680  covering the opening  690 . The lid may include a central downward projection that fits tightly in the circular can opening, and may include an annular protrusion sized to fit snugly within the ring groove  684  of the rim. In the brush keeper assembly of the disclosure as shown in  FIG.  6 D , the lids of lower paint container  610  and upper paint container  620  are both removed so that an opening of lower paint container  610  faces a corresponding opening of upper paint container in an open end-to-end configuration, resulting in a shared interior space  660 .

In a use case of wet storage using the brush keeper kit  600 , one or more suspended paint brushes  640  may be stored with bristles at least partially immersed in liquid stored in the lower paint container, such as in paint or solvent (not shown). In a use case of wet storage using the brush keeper kit of the disclosure, one or more paint brushes  640  may be stored with bristles suspended above liquid stored in the lower paint container, such as in volatile vapors within the brush keeper interior space. The interface between paint container adapter  630  and upper and lower paint containers  620 ,  610  serves as a barrier to evaporation of volatile materials such as paints and solvents. The paint container adapter  630  prevents or limits loss of volatile material during a time interval of wet storage. 
       FIG.  6 D  is a sectional view of a brush keeper assembly at the area C of the sectional view of  FIG.  6 B  showing a close-up view of the brush holder  650  and other structures at the junction of upper and lower paint containers. Reference may be had to descriptions of  FIGS.  1 A- 1 E and  5 A,  5 B  for a detailed description of edge surfaces of the container engagement section of the support clip  652 . A first segment is configured to engage an inner sidewall surface  670  of the container extending below the rim  680 , and a second segment is configured to engage an inner edge  685  of the container rim ( FIG.  6 C ). The edge surfaces may further include an intermediate segment extending between the first segment and the second segment, wherein the intermediate segment is configured to engage a lower surface  676  of the rim ( FIG.  6 C ). In an embodiment, the second segment includes a hook  656  configured to fit over an upper lip  686  at the inner edge of the rim, and a portion of the second segment is configured to engage an inner edge surface  688  at the inner edge of the rim. In an embodiment, the first segment and the intermediate segment form a convex angular member  658  configured to fit into a recess  674  at a lower surface of the rim adjacent the sidewall. In an embodiment, the first segment includes a protrusion  654  configured to abut against the inner sidewall surface  670  of the container in order to adjust orientation of the support clip. In an embodiment, the support clip  652  snaps into place and is frictionally retained by the rim and the sidewall. 
       FIGS.  7 A- 7 D  show an embodiment of a paint container adapter  700 . The paint container adapter  700  is generally similar to the paint container adapter  400  shown in  FIGS.  4 A- 4 C  and reference should be had to the description of paint container adapter  400  for details of corresponding structures of paint container adapter  700 . In addition,  FIGS.  7 A,  7 C  show illustrative dimensions of paint container adapter  700 . The sectional view of  FIG.  7 C  and the partial sectional view of  FIG.  7 D  show interior surfaces of the outer rim  730  include bumps  750  to aid retention of the lower container within the lower section  720  and to aid retention of the upper container within the upper section  710 . 
     The foregoing method descriptions and the interface configuration are provided merely as illustrative examples and are not intended to require or imply that the steps of the various embodiments must be performed in the order presented. As will be appreciated by one of skill in the art, the steps in the foregoing embodiments may be performed in any order. Words such as “then,” “next,” etc., are not intended to limit the order of the steps; these words are simply used to guide the reader through the description of the methods. Although process flow diagrams may describe the operations as a sequential process, many of the operations can be performed in parallel or concurrently. In addition, the order of the operations may be re-arranged. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc. When a process corresponds to a function, its termination may correspond to a return of the function to the calling function or the main function.
