The present disclosure relates to dental care implements and more particularly to dental flossers.
Dental flossers are known for simplifying the task of flossing teeth. One type of known dental flosser is generally F-shaped and includes an elongated handle and a pair of arms or forks between which a length of dental floss extends. The handles and forks of these flossers are typically over molded onto a length of floss to provide an integral, single-use dental flosser.
Standard injection molding manufacturing techniques for single-use flossers produce large batches of loose, individual flossers. Because of their relatively light but somewhat variable weight, in many instances reliably packaging large numbers of individual flossers into a single package involves manually counting the flossers. Often batches of flossers are loosely packaged, for example in a batch of 100 flossers, within a flexible bag, which is often resealable. Over time flossers packaged in this manner can become entangled with one another, making removal of an individual flosser difficult.
Accordingly, there is a need for improvements in flosser design that facilitate one or more of efficient manufacturing processes, easier packaging, and more convenient dispensing of individual flossers.
In some aspects, a set of dental flossers includes a plurality of flossers, each flosser includes a handle portion and a yoke portion. The handle portion of each flosser includes a first edge and a second edge. The first edge of each flosser is coupled to the first edge of an adjacent flosser by at least one first connecting member. Two of the flossers comprise end flossers, and the second edge of each of the plurality of flossers except for the end flossers is coupled to the second edge of an adjacent flosser by at least one second connecting member.
Each flosser in the set may be substantially identical to the other flossers in the set. At least one of the first edge and second edge of each flosser may be substantially straight. The handle portion of each flosser may be substantially triangular. Each yoke portion may support a respective length of floss. Each length of floss may be substantially parallel to the other lengths of floss. A first reference line extending generally in a direction of the first edges may define an angle A with respect to a second reference line extending generally parallel to the lengths of floss, and a third reference line extending generally in a direction of the second edges may define an angle B with the second reference line. The angle A may be less than the angle B. The yoke portion of each flosser may include a proximal arm and a distal arm, and the length of floss of each flosser may extend between the proximal arm and the distal arm of its respective yoke. Each first edge may extend generally toward the distal arm of its respective flosser, and each second edge may extend generally toward the proximal arm of its respective flosser. The first and second connecting members may be breakable by bending each flosser relative to one of its adjacent flossers. Two first connecting members may connect each coupled pair of first edges to one another, and two second connecting members may connect each coupled pair of second edges to one another. The set may be integrally molded and formed of a single piece of injection molded plastic. Each first connecting member may be located a distance from a nearest end of the first edge to which it is attached that is between about 20% and about 45% of a length of the first edge to which it is attached.
In other aspects, a set of dental flossers includes a first group of dental flossers oriented in a first direction. Each flosser in the first group of flossers includes a length of floss, and each length of floss in the first group of flossers is substantially collinear with the other lengths of floss in the first group of flossers. The set also includes a second group of dental flossers oriented in a second direction and coupled to the first group of dental flossers. Each flosser in the second group of flossers includes a length of floss, and each length of floss in the second group of flossers is substantially collinear with the other lengths of floss in the first group of flossers.
The lengths of floss in the first group of flossers may be substantially parallel to the lengths of floss in the second group of flossers. Each flosser in the first group of flossers may be directly connected to at least one flosser in the second group of flossers by at least one connecting member. Each flosser may include a generally triangular handle portion and a yoke portion extending from the handle portion.
Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the accompanying drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
The handle portions 22 of the flossers 14 in the set 10 are interconnected with one another by the connecting members 18. In the illustrated configuration, each flosser 14 is connected to at least one adjacent flosser 14 by at least one connecting member 18 that extends between the handle portions 22 of the respective flossers 14. More specifically, each handle portion 22 includes a first edge 50 extending substantially from the pick 30 toward the distal arm 38b, and a second edge 54 extending substantially from the pick 30 toward the proximal arm 38a. The flossers 14 in the exemplary illustrated configuration are arranged generally in a line and in an alternating or nested arrangement such that the first edge 50 of each flosser 14 is adjacent to the first edge 50 of an adjacent flosser 14 and, with the exception of the two end flossers 14a located at the ends of the set 10, the second edge 54 of each flosser 14 is adjacent the second edge 54 of its adjacent flosser 14. As a result, in the illustrated arrangement each flosser 14 except for the two end flossers 14a is interconnected with two adjacent flossers 14, one that is adjacent its first edge 50 and one that is adjacent its second edge 54. The illustrated alternating arrangement provides a first group of flossers 14 oriented in a first direction and having lengths of floss 42 that are substantially collinear, and a second group of flossers 14 oriented in a second direction opposite the first direction and also having lengths of floss that are substantially collinear. The lengths of floss 42 of the first group and the lengths of floss 42 of the second group are substantially parallel. As a result, all of the lengths of floss 42 are substantially parallel with each other (with some of the lengths of floss 42 also being collinear with each other). In the illustrated configurations, the first and second edges 50, 54 are substantially straight, in other configurations the first and second edges 50, 54 may include non-straight features such as curves, waves, or angular features that are complimentary to one another to facilitate an alternating or nested arrangement.
While the first and second edges 50, 54 may take on a variety of configurations, the overall configuration of the illustrated handle portions 22 of each flosser 14 is generally triangular. This generally triangular shape, defined generally by the first and second edges 50, 54 and the base of the yoke portion 26, allows the handle portions 22 to include a pointed proximal end defining the pick 30, and an enlarged distal end that facilitates gripping and maneuvering of the flosser 14. The generally triangular shape also allows the flossers to nest closely together within a reduced footprint. In the illustrated configuration, and with reference to

The connecting members 18 are configured to be easily breakable by a user by bending a flosser 14 at the end of a set 10 relative to its adjacent flosser 14 about an axis substantially extending through the connecting members 18. For example, with reference to
Once a flosser 14 is separated from the set 10, all or a portion of one or both connecting members 18 may remain attached to the flosser 14. To reduce the likelihood of user discomfort as a result of the remains of a connecting member 18 contacting the soft tissues within the mouth, the connecting members 18 may be positioned at locations along the first or second edges 50, 54 that substantially coincide with where the user is likely to place his or her finger during a use. In this way, the user's finger covers the remains of the connecting member 18 and reduces the likelihood of the remains of the connecting member 18 contacting the inside of the user's mouth. In some exemplary embodiments, at least one of the connecting members 18 is located a distance from the nearest end of the first or second edge 50, 54 to which it is attached that is between about 20% and about 45% of the length of the first or second edge 50, 54 to which it is attached. In other exemplary embodiments, at least one of the connecting members 18 is located a distance from the nearest end of the first or second edge 50, 54 to which it is attached that is between about 25% and about 40% of the length of the first or second edge 50, 54 to which it is attached. In still other exemplary embodiments, at least one of the connecting members 18 is located a distance from the nearest end of the first or second edge 50, 54 to which it is attached that is between about 30% and about 35% of the length of the first or second edge 50, 54 to which it is attached. In still other exemplary embodiments, the connecting members 18 located on the first edge 50 are each located a distance from the nearest end of the first edge 50 that is between about 20% and about 45% of the length of the first edge 50. In still other exemplary embodiments, the connecting members 18 located on the second edge 54 are each located a distance from the nearest end of the second edge 54 that is between about 20% and about 45% of the length of the second edge 54.
