Description

PAINT BRUSH PROTECTOR AND SHAPER Field of the Invention.

The present invention relates to paint brush protectors and shapers and in particular to paint brush protectors for protecting the paint brash bristles from damage or deformation.

Background Art.

Various paint brush protectors are available in the art including those used currently to protect paint brashes prior to sale and subsequently.

Paint brash protectors that are included with a paint brash when they are sold are typically manufactured of paper or cardboard and are not intended to protect the brash after the first use of the brash. They are generally removed and disposed of by the purchaser.

Once a user realises that the brash needs protecting, generally a further paint brash protector is purchased. These paint brash protectors are generally of a more robust or permanent construction than the cardboard or paper of the temporary paint brush protector provided when the brash is sold.

These protectors are many and varied in type. One prior art protector has a cavity in the brash protector which enables the brash to be contained within the brash protector. The brash protector has hinges which enable the brash protector to be folded to form the cavity to contain the brash. The brash is retained in the brash protector by a string which is attached to a button with the first end of the string attached to the button, the string then wrapped around the brash. If desired, the second end of the string can be attached to the string or wrapped around the button to more securely retain the brash in the cavity of the brash protector. Air holes facilitate drying of the brash when it is contained in the cavity of the brash protector.

Another protector of the prior art is one in which a pouch is provided for the paint brash. The handle of the paint brash is placed into the pouch first and it extends through an opening provided in one of the sidewalls of the pouch. The rest of the brash including the attachment portion between the bristles and the handle are then received by the pouch. A flexible flap is provided which can then be closed and secured to maintain the brash within the pouch.

The main problem with this pouch and pouches of this kind is that the bristles of the brush are received in the pouch as well as the shoulders. When removing the brush from the pouch, the bristles catch on the inside surface of the pouch and continued movement of the brush out of the pouch generally damages the bristles which is contrary to the purpose of the protector. It will be clearly understood that, if a prior art publication is referred to herein, this reference does not constitute an admission that the publication forms part of the common general knowledge in the art in Australia or in any other country.

Summary of the Invention.

The present invention is directed to a paint brush protector and shaper which may at least partially overcome at least one of the abovementioned disadvantages or provide the consumer with a useful or commercial choice.

In its broadest form, the invention resides in a paint brush protector and shaper for a paint brush having a handle, shoulders and bristles, the protector including a first portion and a second portion, each portion provided with at least one sidewall with at least a par of an engagement assembly wherein the parts of the engagement assembly are engageable to close the protector.

In one form, the invention resides in a paint brush protector and shaper for a paint brush having a handle, shoulders and bristles, the protector including a first portion and a second portion engageable with the first portion to close the protector, at least one of the portions having a housing portion to engage and surround the shoulders of the brush leaving the bristles at least partially free, the housing portion having an opening therein to receive the handle of the brush therethrough, wherein when loading the brush into the protector, the handle of the brush is inserted through the opening until the housing engages the shoulder such that the bristles enter the shaper after the shoulders are engaged.

The protector is generally manufactured of a material that is suitable for immersion in a cleaning solution of water or other cleaning substance such as spirits. The material will preferably be a plastics material but may be a metal.

The protector of the invention includes a first portion and a second portion engageable with the first portion to close the protector. Generally speaking, the portions of the protector will engage each other to enclose the bristles of the paint brush and protect the bristles from damage. The portions preferably include one or more hinge means to attach the portions relative to one another. Suitably, there is a single hinge located at one end of the portions. The hinge means can be any suitable hinge means. For example, the hinge means may be a series of corresponding tubular portions which are then collocated and a hinge pin driven through the portions. Alternatively, the hinge means may be as simple as a fold line formed between the two portions allowing them to fold about the line.

Each portion may be substantially rectangular when viewed in plan, having a substantially planar body portion having a pair of side edges, a handle-end edge and a bristle-end edge. The hinge is suitably located at the bristle-end edge of each of the portions. Alternatively, it is also acknowledged that the hinge may be at the handle end. Each portion suitably has a wall portion extending along three of the four edges of each portion, the edge not having the wall portion suitably being the hinged end. The wall portions extend substantially perpendicularly from the planar body portion.

The wall portion may decrease in height from the handle-end of the protector to the bristle-end. Paint brushes are normally constructed such that the handle of the brush is thicker than the bristles where they attach to the handle and the bristles themselves taper from the handle-end of the brush to the extremity of the bristles. The wall height of the wall portion of each portion at the handle-end of the portion will therefore generally be slightly greater than the thickness of the handle at that point. The wall height of the wall portion of each portion at the bristle-end of the portion will generally be slightly greater than the thickness of the bristles at that point. The wall portions may assist with maintaining the shape of the bristles as well as further protecting the bristles from damage.

One of the portions is preferably slightly larger than the other portion meaning that the wall portions of the larger portion will, when the protector is closed, suitably surround the wall portions of the slightly smaller portion. The larger portion may also suitably have a opening through the handle-end of the portion to allow the larger portion to be closed but still accommodate the handle of the brush. The opening may typically extend the entire height of the wall portion at the handle-end of the portion and a width appropriately suited to the width of the handle of the brush to be contained. This may create a pair of tab portions out of the wall portion at the handle-end of the portion.

Each of the tab portions will preferably have a locking means located at the top of the tabs furthest from the planar body portion. The locking means will generally be a bulbous portion which extends into the cavity formed for the brush. When the protector is closed, the bulbous portion will suitably engage the planar body portion of the other portion to maintain the protector in the closed condition until a force is applied. This may prevent or minimise accidental opening of the protector.

Alternatively, the locking means may be a bulbous portion or shaped portion in the sidewall extending outwardly from the cavity. Suitably, each of the portions will be provided with a bulbous portion and the locking action may be such that the bulbous portion on one portion is forced to overlap with the bulbous portion on the other portion. Typically, one or more than one bulbous portion may be provided on each portion depending upon the configuration of the shaper and particularly on whether the opening to accommodate the handle of the brush is at the hinge end or the opposing end.

At least one of the portions has a housing portion to engage and surround the shoulders of the brush leaving the bristles at least partially free. Preferably, the smaller of the two portions has the housing. The housing may suitably be an enclosure which extends from the handle-end of the portion towards the bristle- end. Suitably, the housing is approximately equal in length to the attachment portion of the brush where the bristles attach to the handle. This portion is generally approximately 2.5cm in length but that dimension depends on the size of the brush. Suitably, the housing does not extend to the bristles of the brush. The housing may be formed by a transverse extending wall member extending from the wall portion on one side of the portion to the wall portion on the other side. The housing portion has an opening therein to receive the handle of the brush therethrough. The opening is suitably in the end wall portion of the housing.

When loading the brush into the protector, the handle of the brush is inserted through the opening until the housing engages the shoulder such that the bristles enter the shaper after the shoulders of the brush are engaged. This generally occurs on an angle. The bristles are then lowered into the cavity formed by the wall portions and the larger portion is then closed on the smaller portion enclosing the brush.

Paint brushes are generally sold in a variety of standard sizes. The protector and shaper of the present invention will typically be available in a number of different sizes to accommodate the different sizes of brushes. Another important variation is that the protector may be available with an angled hinge. Paint brushes are available with an angled handle or with the bristles having an angled end. The protector may be adapted to facilitate brushes of this nature.

Detailed Description of the Invention.

According to a preferred embodiment of the present invention, a paint brush protector and shaper 10 is provided.

The paint brush protector and shaper 10 is designed to receive a paint brush having a handle, shoulders and bristles. The protector 10 has a first portion 11 and a second portion 12 engageable with the first portion 11 to close the protector 10. At least one of the portions has a housing portion 13 to engage and surround the shoulders of the brush leaving the bristles at least partially free. The housing portion 13 has an opening 14 therein to receive the handle of the brush therethrough. When loading the brush into the protector 10, the handle of the brush is inserted through the opening 14 until the housing 13 engages the shoulder of the brush such that the bristles enter the protector 10 after the shoulders of the brush are engaged. The protector 10 is manufactured of a material that is suitable for immersion in a cleaning solution of water of other cleaning substance such as spirits. The material will generally be a plastics material. The first 11 and second 12 portions engage each other to enclose the bristles of the paint brush and protect the bristles from damage.

The portions are joined by a hinge 15 located at one end of the portions. The hinge 15 illustrated in the figures is a series of corresponding tubular portions which are then collocated and a hinge pin driven through the portions.

Each portion is substantially rectangular when viewed in plan, having a substantially planar body portion having a pair of side edges, a handle-end edge and a bristle-end edge. The hinge 14 is located at the bristle-end edge of each of the portions. Each portion has a wall portion 17 extending along three of the four edges of each portion, the edge not having the wall portion 17 being the hinged end. The wall portions 17 extend substantially perpendicularly from the planar body portion 16.

The wall portion 17 decreases in height from the handle-end of the protector to the bristle-end. Paint brushes are normally constructed such that the handle of the brush is thicker than the bristles where they attach to the handle and the bristles themselves taper from the handle-end of the brush to the extremity of the bristles. The wall height of the wall portion 17 of each portion at the handle-end of the portion will therefore be slightly greater than the thickness of the handle at that point. The wall height of the wall portion 17 of each portion at the bristle-end of the portion will be slightly greater than the thickness of the bristles at that point. The wall portions 17 assist with maintaining the shape of the bristles as well as further protecting the bristles from damage.

One of the portions is preferably slightly larger than the other portion meaning that the wall portions 17 of the larger portion will, when the protector 10 is closed as illustrated in Figure 3, surround the wall portions 17 of the slightly smaller portion. The larger portion 12 will also suitably have an opening 18 through the handle-end of the portion to allow the larger portion 12 to be closed but still accommodate the handle of the brush. The opening 18 extends the entire height of the wall portion 17 at the handle-end of the portion and has a width appropriately suited to the width of the handle of the brush to be contained. This creates a pair of tab portions 19 out of the wall portion at the handle-end of the larger portion 12.

Each of the tab portions 19 has a bulbous portion locking means 20 which extends into the cavity 21 formed for the brush. When the protector 10 is closed, the bulbous portion 20 will engage the planar body portion 16 of the other portion 11 to maintain the protector 10 in the closed condition until a force is applied. The smaller of the portions 11 has a housing portion 13 to engage and surround the shoulders of the brush leaving the bristles at least partially free. The housing 13 is an enclosure which extends from the handle-end of the portion towards the bristle-end. The housing 13 is approximately equal in length to the attachment portion of the brush where the bristles attach to the handle. This portion is generally approximately 2.5cm in length but that dimension depends on the size of the brush. Suitably, the housing 13 does not extend to the bristles of the brush. The housing 13 is formed by a transverse extending wall member 22 extending from the wall portion 17 on one side of the portion 11 to the wall portion 17 on the other side. The housing portion 13 has the opening 14 to receive the handle of the brush therethrough in the end wall portion of the housing 13.

When loading the brush into the protector, the handle of the brush is inserted through the opening 14 until the housing 13 engages the shoulder such that the bristles enter the protector 10 after the shoulders of the brush are engaged. This generally occurs on an angle. The bristles are then lowered into the cavity 21 formed by the wall portions 17 and the larger portion 12 is then closed on the smaller portion 11 enclosing the brush. The protector and shaper 10 of the present invention will typically be available in a number of different sizes. Examples of the sizes available to suit the different sizes of brushes is as follows (Dimensions illustrated n Figure 1):

A further embodiment of the present invention is illustrated in Figures

4 to 6. According to this embodiment, each of the portions 11, 12 is provided with a bulbous portion 20 and the locking action is such that the bulbous portion 20 on one portion 11 is forced to overlap with the bulbous portion 20 on the other portion 12.

According to this embodiment, the shaper lacks a housing.
