The present invention relates to toothbrushes. More particularly, the present invention relates to collapsible toothbrushes and associated toothbrush carrying cases.
Traditional toothbrushes suffer from a variety of disadvantages, especially relating to portability, reusability, and ecological friendliness.
Regarding portability, the traditional toothbrush tends to be about six to seven inches long. This size is not convenient for travel nor carrying on one's person. It would be convenient if a quality toothbrush could be made portable by having one half to one third of the traditional size when being transported.
Also regarding portability, a number of associated items are typically desired for travel along with the toothbrush itself. Specially, toothpaste, dental floss, and mouthwash or breath fresheners are often desired. In the past, travel kits have been available for carrying a collection of these items. However, such traditional kits are bulky and inconvenient because they must accommodate a six or seven inch toothbrush together with a bulky tube of toothpaste, and floss often tossed into an oversized travel case compartment. What is needed is an innovatively designed carrying case system that is extremely compact yet carries all the desired items in a very user-friendly configuration.
Regarding reusability, the traditional toothbrush wears out in two to three months' time, at which point the old brush must be disposed of, and a new brush must be purchased. Therefore, the entire toothbrush, including the substantial portion of it, which is the handle and the head, is often of poor quality and made of cheap materials so that it can be regularly replaced less expensively. What is needed is a high-quality toothbrush that has its substantial portions, namely the handle and head, made of premium materials and which never needs to be disposed of.
Regarding ecological friendliness, and environment sustainability, traditional toothbrushes are again very troublesome. This is because millions of non-biodegradable toothbrushes, made of plastics and other environmentally unfriendly materials, are thrown away every year. What is needed is a toothbrush system that minimizes any disposable elements.
In exemplary embodiments of the present invention, a collapsible toothbrush and associated carrying case are provided that address the shortcomings of the traditional toothbrush and toothbrush travel inconveniences.
Specifically, an elegantly designed toothbrush is provided that is made of premium materials, will last indefinitely, and can be broken down for a portable length of roughly half to one third of the size of a traditional toothbrush. In exemplary embodiments, a carry case is provided that contains the toothbrush and associated items in a very compact and user-friendly way.
Additionally, in exemplary embodiments, a toothbrush design is presented wherein only the bristle assembly need be disposed of once well worn. Consequently, the substantial portions of the toothbrush, namely the handle and head, can be made of premium materials with premium quality because they will last indefinitely. Moreover, this configuration is environmentally friendly because the bulk of the toothbrush does not need to be disposed of. Rather, only the very small bristle assembly is regularly replaced.
In an aspect of the invention, a collapsible toothbrush comprises: a toothbrush head comprising a bristle assembly; and a handle comprising one or more portions. In an embodiment, the toothbrush head is removably attached to a first end of the handle via a first connection. In an embodiment, the one or more portions are removably attached to each other via a second connection to form the handle.

In an embodiment, the toothbrush head is shaped to snuggly receive and hold the rear portion of the bristle assembly. In an embodiment, the rear surface of the rear portion comprises a protrusion. In an embodiment, the toothbrush head comprises an opening shaped to snuggly receive the protrusion.
In another aspect of the invention, a carrying case comprises: a housing; a handle compartment disposed in the housing; a toothbrush head compartment disposed in the housing adjacent to the handle compartment; and a first cover movably attached to the housing via a third connection. In an embodiment, the first cover forms a portion of the toothbrush head compartment and a portion of the toothbrush head compartment.
In an embodiment, the third connection is a hinge.
In an embodiment, the carrying case further comprises: a consumables compartment disposed in the housing adjacent to one or more of the handle compartment and the handle compartment; and a second cover movably attached to the housing via a fourth connection. In an embodiment, the second cover forms a portion of the consumables compartment.
In an embodiment, one or more of the third connection and the fourth connection are a hinge.
In an embodiment, the carrying case further comprises: a dental floss drawer disposed in the housing adjacent to one or more of the handle compartment and the toothbrush head compartment. In an embodiment, the dental floss drawer is movably attached to the housing via a fifth connection.
In an embodiment, the fifth connection is selected from the group consisting of an integral slotted track, a sliding mechanism, and combinations thereof.
In an embodiment, the dental floss drawer further comprises: a dental floss spool; a dental floss port; and a dental floss retainer/cutter.
In an embodiment, the dental floss drawer is flush with the housing when not in use. In an embodiment, the dental floss drawer slidably extends outwardly from the housing when in use.
In an embodiment, the carrying case further comprises: a toothbrush head comprising a bristle assembly disposed in the toothbrush head compartment; and a handle comprising one or more portions disposed within the handle compartment.
These and other objects, features and advantages will become apparent as reference is made to the following detailed description, preferred embodiments, and examples, given for the purpose of disclosure, and taken in conjunction with the accompanying drawings and appended claims.
These and other features, aspects, and advantages of the present invention will become better understood with regard to the following descriptions, and accompanying drawings. It is to be noted, however, that the drawings illustrate only several embodiments of the invention and are therefore not to be considered limiting of the invention's scope as it can admit to other equally effective embodiments.

As illustrated in
In certain embodiments, handle elements 207 and 205 are cylindrical and therefore each have a circular cross-section. In certain embodiments handle element compartments 605 and 607 have openings that correspond in shape to the cross-section of the handle elements they are intended to receive. In the illustrated case, the openings are therefore circular.
Moreover, the dimensions of the openings of compartments 605 and 607 are substantially the same, but just slightly larger, than the dimensions (e.g. the diameter of the cross-section) of the respective handle elements. Consequently, when the handle elements are inserted in the direction of their longitudinal axis into the compartments, the elements are retained snuggly such that they cannot move substantially laterally. This configuration is particularly desirable because the handle elements do not rattle inside the carrying case when transported.
