The present invention provides a coil brush having one or more brush heads with any brush head parallel to any other. The brush heads may have a head base, a bristle slide or guide, and bundles or groups of straight and/or angled bristles, which may be interspersed in different arrangements in a head base of the head brush head, allowing for a variety of brushing planes. The coil brush may further comprise a rear mount handle or a detachable handle that allow the user to adjust the position of the brush to better access and clean coils in hard to reach places. The bristle slide allows the user to control the stiffness of the bundles of bristles by controlling the spreading of the bristles. This invention allows the brushing of coils in heating ventilation and air conditioning equipment at a variety of angles from a variety of coil access points.

A paint brush having an adhesive attachment that includes an engagement of a mass of adhesive within one or more pockets in a lower portion of the handle and an engagement of the mass of adhesive with an internal surface of the ferrule to form a permanent assembly. At least one flow passage fluidly connects with the pocket(s) to facilitate and/or permit flow of the adhesive into the pocket(s) during manufacturing of the paint brush. In addition, the paint brush may include an elongated upper portion having a rigid internal spine that is overlayed and surrounded with a more flexible grip.

A bristle insert, in particular for a brush, is formed by at least one bristle pack having a plurality of plastic bristles whose ends are fused to each other to form a self-supporting holding element. A brush with such a bristle insert, and a method for manufacturing such a bristle insert is also provided.

A toothbrush capable of inhibiting damage of an oral cavity of a user that includes: a head section that has a bristle implanting surface on a front end side; a handle section that is disposed on a rear end side from the head section and has a handle section main body; and a neck section that is disposed between the bristle implanting surface and the handle section. The toothbrush has a deforming portion that is located on the rear end side from the bristle implanting surface and is deformed, while stress characteristics associated with bending due to an external force acting on the head section are in a plane stress condition.
