  • Patent number: 8336967
    Abstract: The present invention provides a method of tapering bristles for toothbrushes and a toothbrush having bristles manufactured using the method. One method disclosed in the present invention includes setting bristles made of polyester in a head insert, and fastening the bristles to the head insert by thermally welding portions of the bristles, protruding from a back surface of the head insert, to the head insert. The method further includes coupling the head insert to a toothbrush body and tapering ends of the bristles by immersing the bristles in a chemical. The bristles can be securely set in the toothbrush body without an anchor. Furthermore, polyester bristles, which could not be set in toothbrushes having variously shaped setting rows due to excessively high stiffness, can be set in these types of toothbrush by the toothbrush manufacturing method of the present invention.

  • Publication number: 20120317737
    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: 8333436
    Abstract: The present invention relates to a method of tapering a toothbrush bristle which increases production efficiency. The method includes the steps of cutting bundles of toothbrush bristles; and non-directionally immersing the entire cut bundles of toothbrush bristles into a chemical solution to taper both sides of the toothbrush bristles. According to the present invention, the production efficiency of a needle-shaped bristle is increased approximately three-fold, and the loss of raw materials is greatly decreased because several processes are not performed.

  • Publication number: 20120284944
    Abstract: The oral hygiene device, particularly a toothbrush, has in the neck part, a cavity, which is closed off from the surroundings and in which a snap dome is arranged. This snap dome produces an acoustic warning signal when a limiting bending of the neck part is exceeded as a result of a limiting pressing force with which the head part is pressed, for example, against the teeth and gums is exceeded. On the one hand, this has the effect of protecting the snap dome, usually produced from metal, from corrosion and, on the other hand, the cavity serves as a resonance chamber to amplify the warning signal.

    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.

  • Patent number: 8186765
    Abstract: The present invention provides a method of manufacturing a toothbrush having needle-shaped bristles and a toothbrush manufactured using the method. The method of the present invention includes the step of grinding bristles, which have been set in a head part of a toothbrush, using a grinder provided with protrusions (11) having heights ranging from 1.5 mm to 7 mm. According to the manufacturing method of the present invention, a toothbrush having needle-shaped bristles can be manufactured without a separate chemical immersion process such that the thicknesses of the end points of the needle-shaped bristles range from 0.01 mm to 0.03 mm and the lengths of the tapered portions thereof range from 3 mm to 9 mm. Furthermore, because the process is simplified, the time required for production and the defective proportion is markedly reduced. As well, in the present invention, materials other than polyester can be used as the material for the bristles, unlike the conventional arts, in which this is impossible.

The manufacturing method of the present invention includes the steps of cutting and removing a packing sheet, which is wound around a bundle of bristles, by a length ranging from 30 mm to 50 mm from a first end thereof, and grinding first ends of the bristles using a rotating grinder. The manufacturing method further includes steps of packing the first end of the bundle of bristles, from which the packing sheet is removed, using a packing sheet, cutting the bundle of bristles to a length ranging from 22 mm to 32 mm, and immersing a second end of the cut bundle of bristles, thus tapering second ends of the bristles. The needle-shaped bristle has an advantage of realizing a reduction in the proportion of defective products.

  • Patent number: 8132865
    Abstract: A multi-surface sponge product includes a foraminous portion adhered to an abrasive portion to form a unitary product, each portion and the resulting product having a pair of sidewalls and in cross-section or side elevation having the form of a parallelogram. The sidewalls form gripping areas and the angled forward and reward end opposite ends of the parallelogram shaped body form wedges. The multi-surface body is low profile and various edges and corners thereof enable the foraminous and abrasive portions to be selectively used to engage corners of many differently configured surfaces to be cleaned, to either scrub the surface or simply clean or absorb fluid, depending on which portion of the product is emplaced in the edge or in a corner.

  • Publication number: 20120056466
    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: 20120013169
    Abstract: In a method for producing bristle areas for brushes, in particular toothbrushes, bundles of bristles (5) are divided off from a bristle supply (101), transported by a gas or air stream (Pf 1) and introduced into perforations (22) in a central plate (21). The bundles of bristles (5) are removed from the central plate (21) and transferred to a compactor plate (106) and, in the process, the density of the bundle of bristles (5) is increased.
