Abstract

A paint brush handle (15) is provided. The handle includes an elastomeric body (40) and a reinforcement core (30). The body has a first level of flexibility and the core has a second level of flexibility, which is less than the first. The core extends through at least part of the length of the body to reinforce the softer material and provide a handle with a compressible, resilient grip characteristic.

Description

HANDLE FOR A PAINT BRUSH
The present invention relates generally to a handle for a paint brush and particularly to a handle comprising an elastomeric portion.
It is known to form paint brush handles from rigid materials such as wood and plastics. However, such handles do not provide great comfort and cannot easily be gripped.
It is known from US 6,408,474 to provide a paint brush handle with a gripping portion made of a flexible elastomeric material. However, because the grip portion is formed entirely from the elastomeric material it must be relatively rigid so that it can maintain its shape and provide a certain level of resistance towards indentation caused by gripping. It is also known to provide a handle with a rigid core covered with a thin coating of elastomeric material. However, the coating of such handles is so thin that it is not compressible.
The present invention seeks to address the problems with known paint brush handles.
According to a first aspect of the present invention there is provided a paint brush handle comprising an elastomeric body having a first level of flexibility and a reinforcement core having a second level of flexibility which is less than the first level, in which the core extends through the body. By providing a more rigid inner core around which a less rigid body is formed the overall structure of the handle is relatively rigid. This allows extremely soft elastomeric materials to be used to form the body, which allows for the formation of handles with improved comfort and gripping characteristics.
Because the elastomeric material is formed as a body, the body is compressible and forms a resilient gripping member.
The core may extend longitudinally at least part way through the body. The core and body may therefore be coaxial.
The core may extend through at least 50% of the length of the body. This provides support to the body over a significant proportion of its length. It has been found that it is preferable for the core to terminate a distance away from the tip of the body to prevent the core splitting the body during use. The core may therefore extend through the body up to a maximum of 90% of the length of the body.
The core may be flexible along its length. However, because it is always less flexible than the body it provides a reinforcing effect. In some embodiments the core is rigid.
The elastomeric body may comprise a material having a hardness value in the range of Shore AlO to Shore A90. More particularly the material may have a hardness value in the range of Shore AlO to shore A30 and still more particularly in the range of Shore Al 4 to Shore A20. In one embodiment the material has a hardness value of Shore Al 5. The Shore hardness value measures the resistance of plastics towards indentation and provides an empirical hardness value.
The body may be formed from a foamed material, for example foamed polyurethane. Such light cellular materials can be formed by creating bubbles of a gas in the liquid material and then solidifying it.
The body may be formed from a thermoplastic elastomer (TPE).
TPE compounds exhibit a thermoplastic character enabling them to be shaped into articles and when formed possess elastomeric behaviour without requiring cross- linking during fabrication. These materials can therefore be processed as thermoplastics while offering rubber-like properties similar to those of vulcanised rubber elastomers. Moulding using TPE's can be done using short cycle times, they can easily be coloured and are easily recycled; accordingly they are well suited to high volume production of paint brush handles.
The TPE compound may comprise or include a styrene block copolymer (SBS). In some embodiments ethylene modified SBS compounds, known as styrene- ethylene-butylene-styrene block copolymers (SEBS)5 may be used.
It has been found that the hardness of SEBS-based materials can be adjusted by including varying amounts of polypropylene. Other examples of TPE compounds which may be used in the formation of the outer cover include: impact modified polypropylene (which is a blend of polypropylene and un-crosslinked ethylene propylene diene monomer); thermoplastic polyurethanes (based on polyester or polyether), thermoplastic copolyester, melt processable rubbers; and elastomeric polyamides.
The core may be formed from a plastics material such as polypropylene which can be formed into a rigid bone-like structure at the centre of the handle.
It has been found that a combination of a core formed from polypropylene and a body formed from SEBS is well suited for handle formation, not least because these two compounds are chemically compatible.
According to a second aspect of the present invention there is provided a paint brush having a handle as described herein.
According to a third aspect of the present invention there is provided a method of forming a paint brush handle comprising the steps of: - providing an elastomeric body having a first level of flexibility;
- providing a reinforcement core having a second level of flexibility which is less than the first level; and
- forming the body around the core. The core and the body may both be formed by moulding processes, such as injection moulding.
In one embodiment the core is formed by a moulding process and the body is sequentially moulded around the core. If the body is moulded around the inner core at a sufficiently high temperature a thermo-bond will be formed to secure the components together. The thermo-bond may be in addition to or instead of mechanical interlocks formed by having cut-outs, projections and the like in the core around which and into which the material of the body flows.
The inner core and the outer cover may be formed, for example by moulding, separately and thereafter secured together by any suitable means such as by interengagement of cooperating formations or by using adhesive compounds.
The present invention will now be more particularly described, by way of example, with reference to the accompanying drawings, in which:

Figure 18 is a plan view of the handle of Figure 17; and
Figure 19 is a front perspective view of the handle of Figures 17 and 18.
Referring first to Figures 1 to 3 there is shown a paint brush generally indicated 10. The brush 10 comprises a handle 15, a bristle cluster 20 and a metal ferrule 25 for connecting the bristle cluster 20 to the handle 15. The bristles 20 are set into the ferrule 25 by a suitable adhesive, such as an epoxy resin, that extends into internal grooves formed by ribs 26a, 26b in the wall of the ferrule 25.
The ferrule 25 is connected to the handle 15 by a groove formed by a rib 26c in the ferrule 25 and also by fasteners, which in this embodiment comprise nails 27.
Referring now to Figures 4 and 5 the handle 15 is shown in more detail.
The handle 15 comprises an inner core 30 and an outer body 40.
The core 30 comprises a rigid structure formed from polypropylene. The outer body is a softer, elastomeric structure formed around the core 30. The body 40 is formed from a SEBS based thermoplastic elastomer having a Shore hardness value of A14. Accordingly, the core 30 provides a rigid framework onto which the softer body 40 is formed so that the handle 15 is compliant to indentation towards the core 30 during use.
In this embodiment the core 30 is formed by injection moulding and is then used to form part of a secondary moulding process in which the body 40 is sequentially moulded directly around the core 30. The temperature of the secondary moulding process causes thermo-bonding between the core 30 and the body 40.
Referring now to Figures 6 to 9 the core 30 is shown in more detail. The core 30 comprises a generally triangular-shape body 31 having a rectangular base 32, a generally square middle section 33 and an elongate tail section 34 which tapers along its length.
The middle section 33 includes three oval apertures: a central aperture 33a; and two flanking lateral apertures 33b, 33c. The tail section 34 also has an oval aperture 34a. When the body 40 is moulded onto the core 30 the cover material fills the apertures and this helps to secure the components together.
The base 32 comprises three open wells 32a, 32b, 32c which do not become filled with cover material but rather serve to receive adhesive when the ferrule 25 is connected to the handle. In this way the strength of the connection is enhanced.
Referring now to Figures 10 and 11 the body 40 is shown in more detail.
The body 40 comprises a brush head receiving section 41, a central waist section 42 and an end section 43. The "hourglass" shape provided by the waist 42 gives an ergonomic shape to the cover 40.
The receiving section 41 has a perimetral flange 41a positioned so that it is received in the groove formed by the ferrule rib 26c when the handle 15 is joined to the ferrule 25. Referring now to Figures 12 to 14 there is shown a core 130 formed according to an alternative embodiment. The core 130 comprises a generally triangular-shape body 131 comprising: a generally parallelepiped base 132 having an oval section; a rectangular middle section 133 which projects from the base 132 and tapers along its length; and an elongate tail section 134 which extends from the middle section 133 and terminates with a semi-circular tip 134b.
Similarly to the core of Figures 4 to 9, the tail section 134 includes an oval aperture 134a and the base 132 comprises three open wells 132a, 132b, 132c.
Referring now to Figures 15 and 16 the core 130 is shown embedded in a body 140, which in this embodiment is formed from a thermo-plastic elastomer with a hardness value of Shore A15. The body 140 extends from the base 132 of the core 130. The core 130 extends up through approximately 80% of the length of the body 140.
Referring now to Figures 17 to 19 the handle 115 comprising the core 130 and the body 140 is shown in more detail. The bulbous end section 143 of the body 140 is shown tapering to a central waste section 142. The waste section 142 widens and leads to a ferrule-receiving section 141 adjacent the exposed core base 132. The ferrule-receiving section 141 comprises a perimetral flange 141a which is intended to be received in a ferrule rib (not shown).
