To provide a method for manufacturing an interdental cleaning tool that can prevent deformation of a core base at molding of a cleaning flexible part using an elastomer material, thereby effectively preventing occurrence of molding failure of the cleaning flexible part.

The method in the present invention includes: a base part molding step of providing first metal molds 30 and 31 for molding base parts with a plurality of first molding spaces 32 aligned in parallel and including core base molding sections 32a and handle base molding sections 32b, providing the first metal molds 30 and 31 with connection part molding sections 35 to communicate with the adjacent handle base molding sections 32b, and supplying a synthetic resin material with a fiber material at a time to the plurality of first molding spaces 32 from gates 34 to form a plurality of base parts at a time; and a flexible part molding step of setting the core bases of the base parts into second metal molds, holding the core bases at two or more longitudinal portions by a plurality of pairs of hold pins in the second metal molds, each pair including two pins, and charging an elastomer material into the cleaning flexible part molding spaces.

A container for separating, storing, and dispensing dental picks includes a container to receive a sheet of dental picks, wherein the sheet of dental picks includes multiple interconnected dental picks, a separating device to separate the sheet of dental picks into singular dental picks, and a dispensing device to dispense the singular dental picks, one at a time. A method for separating and dispensing dental picks includes obtaining a sheet of dental picks, wherein the sheet of dental picks includes multiple interconnected dental picks, loading the sheet of dental picks into a container, separating the sheet of dental picks into singular dental picks, and dispensing the singular dental picks one at a time.

A toothbrush includes a head with an extendable handle. The toothbrush has a brush head with bristles extending from one side, and an opening containing one or more segments nested within one another. The inner-most segment is pulled outward, away from the brush head, with the adjacent outer segments following forming a handle assembly. A resilient member within the brush head between the head and inner-most segment assists in extension of the handle assembly. Upon extension the segments form an interference fit with each adjacent interior and exterior segment forming a rigid handle assembly. When the handle assembly is in an extended configuration a retention member extends from the interior of the segment surrounding the extended segment for engaging the end of the segment thereby preventing the handle assembly from collapsing. A rotatable collar at the end of the inner-most segment includes filament for flossing teeth.

An elongated core comprising a nylon or polypropylene is extruded. An interdental cleaner portion, comprising fingers, is injection molded about a first portion of the core. The interdental cleaner portion has thermoplastic elastomer. A handle portion is injection molded about a second portion of the core. The handle portion has polypropylene.

In one embodiment, an oral-care system is provided. The oral-care system includes an electric toothbrush having a motor, a power source in electrical communication with the motor, and a bristle holder operatively connected to the motor. A display is in data communication with the electric toothbrush.

An oral care system includes a first package, a second package, and a container. The first package has a first identifier associated with a first time of day. The first package contains a first unit dose suction brush. The first unit dose suction brush includes a first handle, a first cleaning head, and a first vacuum port. The first handle has a first brush first end and a first brush second end opposite the first brush first end, the first handle having a first suction channel extending from the first brush first end to the first brush second end. The first cleaning head is connected to the first brush first end. The first cleaning head includes a first suction port and a plurality of first bristles arranged in a first pattern surrounding the first suction port. The first vacuum port is located at the first brush second end.

A package kit for storing a plurality of products comprises a plurality of primary packages and a secondary package. Each primary package comprises a cavity for storing one of the products. The secondary package stores the plurality of primary packages. The secondary package comprises a back panel and a front panel between which the plurality of primary packages is sandwiched. The front panel comprises at least a first row of a plurality of apertures, wherein the number of apertures corresponds to the number of primary packages for displaying at least a portion of each primary package. The front panel further comprises at least a first outer circumferential portion and a second outer circumferential portion. The first outer circumferential portion partially surrounds the plurality of apertures of the at least first row and is attached at least partially to the back panel, and the second outer circumferential portion is attached at least partially to the back panel. The front panel further comprises an elevated portion being arranged between the first and the second outer circumferential portions. The first outer circumferential portion comprises a first limb and a second limb, and the second outer circumferential portion comprises a third limb and a fourth limb, and the elevated portion extends from the first, the second, the third and the fourth limb, respectively. The elevated portion is hingeably connected to the first, the second, the third and the fourth limb, respectively.

The present invention relates to a system that cycles brushes on a tenter frame system. When the bristles of first brush becomes engorged with latex, the system can move the engorged brush out of the way and move a fresh brush into operation. An operator may then replace the engorged brush with another fresh brush without stopping the tenter line.
