    Abstract: An anti-loose interdental brush includes a plurality of fixing portions formed on a bristle stem of an interdental brush. Each fixing portion includes a bottom wall, a side wall formed laterally from the bottom wall, and a capacity area surrounded by the bottom wall and the side wall. The adjacent bottom walls of the adjacent fixing portions are orientated in different directions. Thus, the adjacent capacity areas are set in different directions to contact the handle. An outer diameter of the bottom wall can be preferably larger than or equal to an outer diameter of the bristle stem. Accordingly, a dual engaging and fixing effect between the bristle stem and the handle is attained to prevent the bristle stem from loosening and rotating due to an external force and to enhance safety in using.

    Abstract: There is a need to reduce raw materials used in the manufacturing of wet mops, to reduce the weight of the wet mop which will decrease user fatigue and related injuries and to address the difficulty of attaching standard wet mops to commonly used mop handles. The improvement is a tubular headband wet mop with yarn strands on only one side of the headband, reducing the amount of unused yarn incorporated into the wet mop while not reducing floor surface coverage area. The tubular headband also eliminates the possibility of exposing the bottom side of the mop handle which can damage or mar the floor surface, coatings and finishes. This reduction in raw materials results in a lighter product, which reduces effort required to lift and wring out the wet mop, and reduces fatigue and injuries associated with mopping.

  • Publication number: 20140304931
    Abstract: A paintbrush includes a handle and a brush extending from an end of the handle. A ferrule circumscribes the end of the handle and a portion of the bristles adjacent the end of the handle. A seal is disposed around an interface between the ferrule and the handle to reduce absorption of chemicals by the handle through the interface.

  • Patent number: 8857919
    Abstract: An oral care implement is provided having a head frame and a cleaning elements assembly attached thereto with tooth cleaning elements extending from one or more carriers. One or more central carriers can be suspended via a flexible bridge between a pair of support carriers attached to the head frame. The bridge may be formed from an elastomer and permit the one or more central carriers to move from an initial position toward the head frame during use. The bridge may include rigid supports and flexible elastomeric supports. The carriers and the bridge can be formed as a unitary assembly attached to the head frame, such as via mechanical connections. The mechanical connections could include snap-fit connections.

  • Publication number: 20140292059
    Abstract: There is a need to reduce raw materials used in the manufacturing of wet mops, to reduce the weight of the wet mop which will decrease user fatigue and related injuries and to address the difficulty of attaching standard wet mops to commonly used mop handles. The improvement is a tubular headband wet mop with yarn strands on only one side of the headband, reducing the amount of unused yarn incorporated into the wet mop while not reducing floor surface coverage area. The tubular headband also eliminates the possibility of exposing the bottom side of the mop handle which can damage or mar the floor surface, coatings and finishes. This reduction in raw materials results in a lighter product, which reduces effort required to lift and wring out the wet mop, and reduces fatigue and injuries associated with mopping.

  • Publication number: 20140295378
    Abstract: The present invention is directed to a debridement and/or implant cleaning tool (1) in which the means for cleaning (4) is made of a biodegradable material. Thus, if parts of the means for cleaning (4) come loose during use, these will be degraded by natural processes in the body and will not remain in the body and cause negative body reactions.

  • Patent number: 8845033
    Abstract: A process for the production of a segment brush a half finished product is first produced, having a bristle fill bent at 90° arranged in a ring like form with a radially outwards pointing angular offset supported on a ring shoulder of a transfer device, seated with the second angular offset on a central arbor, axially moveable in the ring and axially protruding. A holding ring holds the first angular offset axially against the ring shoulder and the second angular offset radially against the arbor. Pressing of the bristle fill is made on the transfer device in a press against the holding ring. A pressing arbor firstly spreads the second angular offset of the bristle fill with an attachment, ejects the center arbor and presses the angular offsets against the ring shoulder of the ring.

  • Patent number: 8845034
    Abstract: A brush head, particularly a toothbrush head, may have a plurality of cleaning elements, in particular bristle tufts, which are anchored by an end section in a brush carrier, wherein the cleaning elements may be cast with positive engagement in blind-hole shaped retaining recesses. For producing such a brush head different cleaning elements may be placed successively or simultaneously in different mold cavities and may be over-molded using different plastic materials from which injection-molding sections of the bristle carrier are formed in the process. In doing so, a first cleaning element is over-molded in a first mold cavity using a first plastic material, while a second cleaning element is over-molded in a second mold cavity using a second plastic material.

  • Patent number: 8840192
    Abstract: In the production of toothbrushes, the neck part and the head part are bent relative to each other from the original shape thereof by a predetermined angle (?) in the hot state of the toothbrush body. Thereafter, the force applied to the toothbrush body by the stretching device in order to bend the toothbrush body is removed so that the toothbrush body can bend back into the original shape thereof. The risk of fractures, in particular brittle fractures, can be greatly reduced by said action. The method is advantageous, in particular, if the toothbrush body was heated during processing by ultrasonic welding.

    Abstract: A twisted wire brush comprises a wire core and at least one length of spring coil. The wire core has a first length, defines a core axis, and comprises at least two core wires intertwined. The core wires twist helically about the core axis. Each length of spring coil extends about at least one of the core wires, and each length of spring coil is pressed between the twisted core wires. In another embodiment, a method of making a twisted wire brush comprises providing at least two core wires, positioning a length of spring coil about each core wire, aligning each length of spring coil, and twisting each core wire about a core axis. In yet another embodiment, a grill brush comprises a handle, a plurality of twisted core wires attached to the handle, and at least one length of spring coil, each length extending about at least one core wire.
