The present invention relates to a personal use device, preferably a toothbrush, a shaving device, or a hair removal device. The invention relates to a refill pack for such a personal use device, having a supply container (), particularly a supply bag, containing at least one hygiene or care substance such as toothpaste or the like, and a pump () tightly connected to the supply container, the pump chamber of which is connected to the interior () of the supply container via an input valve (). By deformation of a membrane which bounds the pump chamber (), the pump chamber volume can be changed. The invention also relates to a method for filling such a refill pack.

Refill pack for a personal use device

An electric toothbrush is disclosed. The toothbrush includes a handle part and an attachment part, wherein the handle part has a housing, in which a reservoir for a care substance, a pump for delivering the care substance and a drive unit for driving the pump are arranged. The housing is divided into a liquid-tight first chamber and a second chamber by a partition extending in the longitudinal direction of the housing. The first chamber housing the drive unit is arranged in the first chamber and the reservoir and the pump are arranged in the second chamber.

Electric toothbrush

A toothbrush head includes a base portion having a first surface and a pivot portion having a first cleaning element holder having a second surface, wherein the second surface is superjacent the first surface. The pivot portion also includes a second cleaning element holder and a third cleaning element holder which extend longitudinally from the first element holder. The head includes a pivot element for pivotally coupling the base portion and the pivot portion.

Brush head for toothbrush

An elongated toothbrush head defining a longitudinal axis includes a first brush member having a first brush support surface and a second brush member which is a pivot arm mounted for pivotal movement on the first brush member. The pivot arm has a second brush support surface including a first portion and a second portion which are joined together and include free ends which are spaced apart. The first portion and the second portion of the second brush support surface are capable of pivoting relative to the first brush support surface about an axis which extends transversely to the longitudinal axis of the head and laterally across the pivot arm. One or more teeth cleaning elements project from the first portion and the second portion and are inclined at an angle to the second brush support surface.

An electric toothbrush including a pressure fluid device for applying fluid under pressure to teeth to be cleaned or to a bristle set. The pressure fluid device includes a pressure fluid supply in the interior of a movable drive translator. A brush part with a carrier tube is movably mounted with a drive translator therein adapted to be coupled to a drive element in a handle part. A movably mounted bristle carrier mounts a set of bristles and is adapted to be driven in an oscillatory manner by the drive translator. A motor in the handle part drives a drive element adapted to be coupled to a drive element in the brush part and with a pressure fluid conveying device driven by the motor. A pressure fluid channel, which directs the pressure fluid to the toothbrush head, is integrated into the drive translator.

A head for a toothbrush including a neck and, first and second sets of one or more bristles each. The first and second sets are indirectly supported by the neck and movable relative to each other such that at least one component of this relative movement causes the bristle(s) of the first set to be raised and/or lowered relative to the bristle(s) in the second set. The first and second sets of bristles both are movable relative to the neck.

A method for producing a plastic part having a first component and a second component connected to the first component. The method includes molding a temporary connection between the first component and a preliminary second component, coating at least a surface region of the first component, separating the first and preliminary second component, and then molding the second component to the first component. The plastic part can be an injection molded part and the components of the plastic part can be made using the same or different plastics.

Methods for producing a molded part

A head for a toothbrush including a neck and, first and second sets of one or more bristles each. The first and second sets are indirectly supported by the neck arid movable relative to each other such that at least one component of this relative movement causes the bristle(s) of the first set to be raised and/or lowered relative to the bristle(s) in the second set. The first and second sets of bristles both are movable relative to the neck.

The invention is directed to an electrically powered dental cleansing device (,) to which a cleansing implement (,) is fitted. In this manner, the cleansing implement (,) can be rotated about its longitudinal axis. The cleansing implement (,) is configured as an integrally formed part comprising a thin and elongate cleansing shaft (,). The cleansing shaft has at least one longitudinal edge and is provided with a plurality of serrations.

Cleansing implement and electrically powered dental cleansing device

An electrically operated tooth-cleaning device being provided with a handle part having an electric drive motor. A hanle part can be connected with an attachment provided with a cleansing tool, with the cleaning tool being capable of being caused to rotate by the drive motor. A first cleaning tool of a first attachment is capable of being connected directly with the drive motor, and cleaning tool of a second attachment can be couple trough a transmission with the drive motor.

Electrically operated tooth-cleaning device

An electrically powered dental cleansing apparatus in which a cleansing implement is coupled to a drive sleeve and adapted to be rotated about a longitudinal axis. The coupling is effected by a resilient member, in particular a spring which includes a slip coupling and/or a buffer zone. Under normal conditions, the slip coupling provides a non-rotative connection between the drive sleeve and the cleansing implement. However, in the event of the cleansing implement seizing in an interproximal space, for example, the slip coupling will slip, thus avoiding potential damage. The buffer zone acts to prevent displacement of the cleansing implement--although intended by the user--in cases where, for example, the cleansing implement is positioned against a tooth surface rather than against an interproximal space.

Electrically powered dental cleansing apparatus

The invention is directed to a dental cleansing implement (101) having a thin, elongate shaft (102) comprising a free end portion (105) suitable in particular for insertion in the interproximal spaces and connected with a mounting portion (6) or the like. The mounting portion (6) is adapted to be coupled to an electric motor drive means of a handle member, and the cleansing implement is adapted to be rotated or oscillated about a shaft longitudinal center line (135). The free end portion (105) of the shaft (102) is made of a flexible material bent in the shape of a crescent (130), approximately.

Dental cleansing implement

The invention is directed to an apparatus for treating the teeth and/or gums. This apparatus includes a treatment tool (1) for removing plaque in particular from the gum margin and/or for stimulating the gingival tissue. The treatment tool (1) is adapted to be set in vibration. For example, it is possible to generate the vibration by an unbalance structure (12) on a drive shaft (7) of the apparatus. The vibration results in a substantial improvement of the tooth cleaning and/or gum stimulating action.
