A device for packaging and applying a makeup product, having a reservoir containing the makeup product to be applied, and an applicator for applying the makeup product, having an applicator member, carried by the stem, having a plurality of fibres, the fibres having a plurality of portions, at least two portions of which are made of different materials, and the fibres not having, in cross section, an articulated zone defined by one of the portions, the portions made of different materials each defining a part of the outer perimeter p of the fibre in section, or one of the portions made of different materials entirely surrounding the other in section and having at least one region that narrows towards the outside.

Disclosed is a new fiber which has a triangular cross section, and which may be used as a substitute for animal hair with comparable pickup and other properties. The disclosure also relates to methods for providing same.

A frayed cable scaling tool is made by fraying the end of a cable so that it forms a wire brush. A collar or other way of keeping the cable from unraveling too much is necessary. When powered by a pneumatic saw power tool, the scaling tool is very effective at removing scale, rust, carbon, or other debris. The flexibility of the cable allows the frayed end of the cable to move vigorously in a random motion, which is effective for scrubbing. For some applications, it is preferred to enclose the cable and/or the collar in a guide tube.

A brush includes a wire core, a round tip formed on a distal end of the wire core, the round tip being unitary with the wire core section and being formed by melting or welding a portion of the wire core at the distal end, and a molded tip attached to the wire core at the distal end via a ball-and-socket connection.

Provided are a toothbrush in which a tapered surface is formed on a tip part of synthetic resin fibers forming a brush and a fiber surface including the fiber tip part is coated with minerals and the toothbrush is provided with a bristle tip (fiber) having appropriate bending strength, and a manufacturing method of the toothbrush. The toothbrush 1 includes a brush in which a mineral component layer is formed on a surface of a synthetic resin fiber 4. The synthetic resin fiber 4a having a tapered surface 4a1 which is formed in a range of 1 mm to 8 mm from a tip occupies 90% or more of the synthetic resin fibers 4 (4a, 4b), and bending strength of the brush at a position of 1 mm from a leading edge of the brush 3 (the synthetic resin fibers 4 (4a, 4b)) is 0.60 N/cm.sup.2 to 2.00 N/cm.sup.2.

A method and device for cleaning and pretreating solar panels is provided. The device comprises a brush having cleaning elements made from silicone foam rubber material. The cleaning elements can be flaps of silicone foam rubber material. A sheet of silicone foam rubber material having two free ends can be attached to a core member such that the two free ends extend away from the core member to form flaps. The solar panels can be cleaned by brushing the solar panel surfaces with the flaps of silicone foam rubber material. The solar panels can also be pretreated by brushing the solar panel surfaces with silicone foam rubber material.

An applicator device for cosmetic and/or hygiene applications, which includes a shaft with a longitudinal axis, a proximal and a distal end as well as a carrier element, wherein at the carrier element there are arranged bristle elements in an anchor-free manner, wherein the carrier element is introduced in a receiving opening or put onto a receiving section at the distal end of the shaft and wherein the carrier element is connected to the shaft and to a respective method.

A saliva sensing device for detecting oral health and/or overall health includes a chemically treated test strip biomarker targeted to identify bacteria in the saliva. A breathalyzer for detecting bacteria in the mouth of a user includes a housing, a sensor, and an analyzer. The sensor is coupled to the housing and extends outwardly therefrom for placing in the mouth of user and for collecting a saliva sample. The analyzer is for testing saliva that contacts the sensor.

Some embodiments of the present invention provide a novel, twisted-in-wire type interproximal brush equipped with yarn strands. According to some embodiments, the yarn strands may be formed of nylon filament having compression memory characteristics.

A brush bar including a central core in the form of a rigid tube, a plurality of outwardly extending bristles in the form of at least one bristle strip, and a sealing material extending over substantially the entire remaining circumferential and axial extent of the brush bar, the at least one bristle strip having a root portion which is sandwiched between the sealing material and the central core or which is attached on top of the sealing material.
