According to an exemplary embodiment, a foolproof periodontal sulcus brush and intrasulcular medicament applicator, having one or two heads, for use in a variety of humans and animals, and its method of use, may be shown and described. The foolproof periodontal sulcus brush and intrasulcular medicament applicator can have offset heads and bristle areas, and include multiple curves of a neck portion—to provide improved access and cleaning ability, and may be separable or combined with toothbrush and/or other oral care brush elements or components, including a motorized or manual handle.

A liquid cosmetic material container includes a sleeve that includes a storage chamber that stores a liquid cosmetic material therein, a bead member that is disposed at a front end of the sleeve, has a through hole extending in an axial direction of the liquid cosmetic material container and configured to store a brush in the through hole, a relay core that is configured to connect the brush and the storage chamber, enter the brush, and send the liquid cosmetic material in the storage chamber to the brush, and a cap that is detachably attached to the sleeve. A rear portion of the through hole has a first cross sectional area, and a front portion of the through hole has a second cross sectional area which is smaller than the first cross sectional area.

A toilet tool handle with retractable tool head cover is disclosed. An elongate tool handle has an end with a tool head connector thereon. A rack gear extending along the handle's longitudinal axis is positioned adjacent the end. An actuator sleeve, slidable along the handle, has a bearing mounted on it which holds a pinion gear engaged with the rack gear. The tool head cover is connected to the pinion gear such that sliding action of the actuator sleeve with respect to the handle slides the pinion gear with respect to the rack gear. Engagement of the pinion gear teeth with the rack gear teeth causes the pinion gear to rotate and causes the tool head cover to rotate from a first position where it encloses the handle end to a second position where it is rotatably retracted away from the handle end.

A method of manufacturing a brush includes providing a core wire section having a proximal end and a distal end, and an integral tip on the distal end, forming a bristle element having a throughbore, and inserting the core wire section into the throughbore until the bristle element is received on the core wire section.

The present invention includes improvements to a device with bristles that makes it possible to perform oral hygiene tasks to remove quickly impurities in the oral cavity, in particular when the user is travelling and does not carry a toothbrush and, due to time constraints, requires quick and effective cleaning. The cleaning device may also include luffa sponges, water-soluble films, spheres with toothpaste or channels that provide flexibility to a membrane which, when bending, generates a vacuum and is placed on the tongue in order to be used as a toothbrush handle. The device provides a better fitting and handling in the mouth of a user, since it avoids the generation of vacuum when actuated, and also has a membrane surrounded by a cylindrical section that allows its handling since it adapts to the tongue.

A dental care apparatus including a head and a handle. The head includes a brush, a massager, and a guard. The brush and the massager extend from opposing side portions of the head. The massager includes a base and a plurality of projections extending from the base to stimulate oral tissue. The base is adapted to change in shape to conform to an interior surface of a mouth. The guard extends along a perimeter of the head to prevent, or at least reduce, traumatic contact with oral tissue. The handle includes an eating utensil and a cleaner. The eating utensil and the cleaner extend from opposing side portions of the handle. The eating utensil includes a reflective surface to facilitate visual inspection of an oral cavity and a bumper rim extending along a perimeter of the handle to circumferentially encase the reflective surface. The cleaner includes a plurality of projections.

A docking station includes a tray and a charging stand. The tray is provided with a cleaning structure configured for self-cleaning of a roller brush of the cleaning robot. The charging stand is detachably mounted to the tray. The above arrangement enables self-cleaning of a cleaning robot and improves user experience, with a simple structure and low cost.

A brush includes a core wire section having a proximal end and a distal end and a plurality of discs received on the core wire section, the plurality of discs defining a brush head. The brush head is shaped by at least one of trimming the plurality of discs of the brush head and/or bending a portion of the core wire section.

A method of manufacturing a brush includes providing a core wire section having a proximal end and a distal end, and an integral tip on the distal end, forming a bristle element having a throughbore, and inserting the core wire section into the throughbore until the bristle element is received on the core wire section.

Systems, methods, and new file formats are provided for printing 3D microstructures. In some implementations, a new file format is provided that defines 3D objects by a wireframe model expressed as a collection of wires. Because wires and their parameters are defined within the new file format, objects may be processed more efficiently and quickly to support 3D rendering operations. Such methods may be used to print new articles, such as eyelashes, bushes, swabs and other novel items.
