Toothbrush with transparent handle
A toothbrush comprises an elongated handle and a head having cleaning elements extending outwardly from the head. At least a portion of the handle is made from a water clear material having low durometer hardness. At least one object may be embedded within the handle. The object would be visible through the outer surface of the handle.
Latest Patents:
Various attempts have been made to provide toothbrushes which would encourage children to brush their teeth. It is known, for example, from U.S. Pat. No. 5,966,769 to provide a toothbrush with a fillable hollow handle. As described in that patent the handle is constructed from a transparent plastic material which contains a decorative fluid within the hollow interior of the handle component. The brush component and handle component are releasably interconnected so that the user can collect various handle components featuring different characters. The handle components and brush components are interchangeable.
SUMMARY OF THE INVENTIONAn object of this invention is to provide a toothbrush having a transparent handle which encourages users, particularly children, to use the toothbrush.
A further object of this invention is to provide such a toothbrush which may contain an object within the handle visible through the outer surface of the handle.
In accordance with this invention the toothbrush comprises an elongated handle and a head secured to one end of the handle. Cleaning elements extend outwardly from the outer surface of the head. At least a portion of the handle is made from a water clear material which has low durometer hardness to enhance sensorial tactility when the user grips the handle.
In a preferred practice of the invention at least one object is embedded within the water clear handle and the object is thereby visible through the outer surface of the handle. The object could be in the form of speckles such as holographic speckles or could be a colorant or could be a figurine. Where the toothbrush is a power toothbrush the object could be the inner workings of the power drive, such as the batteries, the motor and the shaft.
THE DRAWINGS
As shown in
In accordance with this invention at least a part and preferably all of the handle 12 is made of a water clear material having low durometer hardness. Any suitable material may be used. For example, such water clear material is available from Tecknor Apex of Pawtucket, R.I. A preferred low durometer water clear elastomer material has a durometer range of Shore A 1-15. Such low durometer affords an increased sensorial tactility or “grip feel” that is ideal for toothbrushes especially those used for children and the elderly.
Because at least some of handle 12 is made from a water clear material the invention is preferably practiced by embedding at least one object within the water clear material so that the object can be seen through the outer surface of that portion of handle 12. Any suitable object could be incorporated within handle 12 in accordance with this invention. One example of a suitable object would be variously shaped speckles such as holographic speckles 18 which would be embedded throughout the handle 12 as shown in

Any suitable form of cleaning elements may be used for the fixed section having cleaning elements 16 and for movable section 24. The term “cleaning elements” is intended to be used in a generic sense which could include conventional fiber bristles or massage elements or other forms of cleaning elements such as elastomeric fingers or walls arranged in a circular cross-sectional shape or any type of desired shape including straight portions or sinusoidal portions. Where bristles are used, the bristles could be mounted to tuft blocks or sections by extending through suitable openings in the tuft blocks so that the base of the bristles is mounted within or below the tuft block.
The invention can be practiced with various combinations of the same or different cleaning element configurations (such as stapled or in-molded technology bristles, etc.) and/or with the same bristle or cleaning element materials (such as nylon bristles, spiral bristles, rubber bristles, etc.) The cleaning elements could be generally perpendicular to the outer surface of head 14. Some or all of the cleaning elements may be angled at various angles with respect to the outer surface of head 14. It is thereby possible to select the combination of cleaning element configurations, materials and orientations to achieve specific intended results to deliver additional oral health benefits, like enhanced cleaning tooth polishing, tooth whitening and/or massaging of the gums.
The handle 12 could take any suitable form such as having a rounded end 34 such as illustrated in
In the preferred illustrated practice of this invention the handle 12 and head 14 are permanently or non-detachably connected together. The invention, however, could be practiced where the handle and head are detachably secured together such as shown by the dividing line 38 in
Although the various figures individually show different types of objects embedded within the handle, the invention could be practiced with combinations of objects. Thus, for example, the same water clear handle may include speckles such as holographic speckles and/or a figurine which could be made of holographic material and/or could include different colorants throughout or in selected portions of the water clear handle. Such combinations of objects may be included in the power operated toothbrush in addition to the drive mechanism.
The invention could be practiced where the object is embedded in the transparent material such as shown in
The various embodiments thus provide a toothbrush which would have an appearance to attract interest in and encourage use of the toothbrush.
