This application is a National Entry Application of PCT application no CA2016/050426 filed on Apr. 13, 2016 and published in English under PCT Article 21(2), which itself claims benefit of Canadian application Serial No. 2,887,531, filed on Apr. 13, 2015. All documents above are incorporated herein in their entirety by reference.
The present application relates to toothbrush holders.
A toothbrush holder providing protection for a toothbrush head in known in Applicant's published PCT patent application WO2014/078953 (MAUFETTE et al.) published May 30, 2014. In many embodiments of that patent application, a pair of juxtaposed rollers is provided at the ends of biased arms. The rollers allow for the easy insertion and removal of the toothbrush head from an enclosure for storage. In some embodiments, the rollers are shaped concavely to keep the sides of the toothbrush head aligned or guided during insertion and removal, with the benefit that the toothbrush is unlikely to twist with the result that bristles of the toothbrush contact the holder or its enclosure during insertion, storage and/or removal.
U.S. Pat. No. 2,937,910 (Randa) discloses a toothbrush holder with a pair of jaws gripping the toothbrush by its neck. The jaws include two cylindrical pins that are spaced from each other and are mounted in place by resilient side strips that flex when the toothbrush is inserted or removed. These resilient side strips form a passage between the strips for insertion and removal of the toothbrush. However, the side strips come into direct contact with the toothbrush head which leads to hygienic problems as the inside of Randa's holder becomes contaminated by the toothbrush head rubbing against the inside of the holder.
According to the present invention, there is provided a toothbrush holder for holding an individual toothbrush having a head with bristles and a handle, the holder comprising: an enclosure comprising complementary enclosure parts articulated relative to one another to separate while receiving said head and come together when said head is stored within said enclosure, said enclosure being dimensioned for storing said head while providing a spacing between said bristles and an inner side of the enclosure for hygienic purpose; a guide member cooperating with said enclosure parts for guiding said head during insertion and removal of said head into and out of said enclosure; and a biasing member interacting with said enclosure parts for biasing said enclosure parts to be closed, said guide member facilitating said insertion of said head by forcing said enclosure parts to separate against the action of the biasing member.
In embodiments, the toothbrush holder is configured so that when said head is inserted within said enclosure, said guide member and enclosure parts being biased by said biasing member retain said head within said enclosure while leaving a portion of said handle outside said enclosure.
In embodiments, said guide member comprises a roller mounted on each of said enclosure parts for guiding said head. Thereby, said biasing member's force can be used both for the roller action as well as for keeping the enclosure closed around the toothbrush head.
The various embodiments disclosed herein will be better understood by way of the following detailed description with reference to the appended drawings, in which:
When a factory-fresh toothbrush is first used, it provides a sense of comfort that it is clean and safe to use. Once it is used, it has come in contact with oral bacteria and any other germs present in the oral cavity. Rinsing the toothbrush gives some sense of hygiene, however, there is a lingering sense that bristles of an exposed toothbrush head may contain remnant bacteria or germs from the oral cavity and may attract airborne germs as well.
Giving the user a feeling of comfort and security in storage of the toothbrush involves providing a way for the toothbrush to be stored without exposure of the bristles to airborne contaminants and with protection of the bristles against physical contact with other objects.
As shown in
According to a preferred embodiment, the holder 10 includes two enclosure parts 12A and 12B that form an enclosure 12, shown in
The enclosure shells or parts 12A and 12B in the embodiment shown are structured to close with minimal gaps or openings around the head 24 and bristles 26. Interlocking flange 19A closes the gap along the parting line between the shells 12A and 12B, while the flange 19B closes the gap around the neck 22 at the entry to the holder 10. It will be understood that the bristles 26 do not contact the upper part of the flange 19B since the insertion of the head 24 causes the enclosure parts 12A and 12B to separate sufficiently to make way for the bristles 26 entering and exiting the enclosure. Advantageously, the parts 12A and 12B are shaped and sized so that the bristles 26 do not touch the inside of the enclosure 12 for hygienic purposes. Indeed, when the head 24 is stored within the enclosure 12, there is provided a spacing between the bristles 26 and the inner side of the enclosure 12 so as to avoid contamination or soiling of the inside of the enclosure 12.
The biasing of the enclosure parts 12A and 12B is provided, in the embodiment shown, by a biasing member such as unitary clip 14. Other spring or biasing mechanisms can be contemplated and other mechanisms to articulate the enclosure parts with respect to one another can also be contemplated.
The clip member 14 is provided with a locking mechanism in the form of recesses 15A on each end of the clip member that engage protrusions 15B. To release the clip 14, buttons 16 can be depressed to disengage the protrusions 15B from the recesses 15A, to allow the clip 14 to be pulled away. It will be appreciated that the clip 14 could have protrusions while the parts 12A and 12B could have corresponding recesses. Likewise, a clip could be provided with a lift tap to allow the user to pull the clip end away from one part 12A and disengage the clip 14. While a suitable release mechanism for the clip 14 is likewise optional, it is used to provide a way for the user to easily disassemble the holder 10 to clean the inside of the holder.
The enclosure parts 12A and 12B cooperate with a guide member 17 mounted thereon for guiding the head 24 during insertion into and removal from the inside of the enclosure 12. The guide member 17 may include guide rollers 17A and 17B that are mounted respectively on each of the enclosure parts 12A and 12B. Suitable bearings, such as for example the ones shown at 18 in
Furthermore, when the sides of a toothbrush head 24 are made of smooth plastic, it is contemplated that the rollers can simply be replaced by suitable fixed guides that allow the sliding insertion of the head 24 to cause the separation of the parts 12A and 12B against the action of the biasing member 14. This requires some cooperation between the materials, the shape of the head 24 and the guide members, as it is less tolerant than the shaped roller design illustrated in the Figures to a more bluntly shaped head 24 or a head made of rubberized material that would offer much higher friction than a smooth plastic material.
The parts shown in
While the enclosure 12 shown is shaped to fit relatively snugly around the toothbrush head 24 but without the bristles 26 touching the inside of the enclosure 12, it will be appreciated that the enclosure 12 may be oversized to accommodate a wider variety of toothbrush styles and designs.
Referring to
Further details of the rollers, and other configurations and details of the holder are described in Applicant's PCT patent application PCT/CA2013/050733, filed 26 Sep. 2013 (designating the United States) and published as WO2014/078953 on May 30, 2014, the content of which is hereby incorporated by reference as if fully set forth herein.
While the invention has been shown and described with reference to preferred embodiments thereof, it will be recognized by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
