The present application is a nonprovisional application claiming benefit from a prior-filed provisional application bearing a Ser. No. 62/655,264 and filed Apr. 10, 2018, the entity of which is incorporated herein for reference.
FIELD OF THE INVENTIONThe present invention relates to a hair roller for curling hair, and more particularly to a hair roller, which is specifically configured to exhibit an improved hair-curling effect.
BACKGROUND OF THE INVENTIONConventional hair rollers 11 are round rollers generally configured as a hollow right circular cylinder, as shown in
An object of the present invention is to provide a hair roller having a specifically designed configuration, which supports diverse hair styling with an improved hair-curling effect compared to the prior art.
The present invention provides a hair roller, comprising a roller body for wrapping therearound a hair portion, wherein the roller body is cylindrical in shape and has a normally oval cross-section.
The present invention also provides a hair roller, comprising a roller body for wrapping therearound a hair portion, wherein the roller body is a concave cylinder, which has a normally cross section at a top portion and a bottom portion thereof larger than a normally cross section at a middle portion thereof.
The present invention further provides a hair roller, comprising: a roller body for wrapping therearound a hair portion, wherein the roller body is a concave oval cylinder, which has a normally oval cross section at a top portion and a bottom portion thereof larger than a normally oval cross section at a middle portion thereof; and a hair-retaining structure formed on the roller body for grabbing the hair portion.
The above contents of the present invention will become more readily apparent to those ordinarily skilled in the art after reviewing the following detailed description and accompanying drawings, in which:
The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.
An embodiment of a hair roller according to the present invention is configured as an oval cylinder, which has normally oval cross-sections of equal area, as illustrated in
The oval shape of hair rollers is advantageous in several ways. For example, according to life experiences, hair can be retained by an oval roller more easily and tighter than by a round roller. In addition, the number of oval rollers 42 that can be accommodated in a certain area of the user's head is more than that of conventional circular hair rollers 11 (see
In the above embodiments, the oval rollers may be made hollow in consideration of lightweight while saving cost of material. A cushion material such as foam 501 can be added to the inside of the roller body 500 for comfort when the rollers are used overnight upon sleep, as illustrated in
In another embodiment of the present invention, an oval roller may be made solid and includes one or more heating elements. A cross-sectional view of an exemplified solid oval roller 50 is schematically illustrated in
It is to be noted that although the concave hair rollers as described above with reference to
It is to be noted that although the oval rollers described in the above embodiments have oval cross-sections, the oval cross-sections do not have to be symmetrically right or smoothly oval. Instead, minor or local modifications can be made according to the spirit of the present invention and practical requirements. For example, the oval cross sections may be leaf-shaped having a larger radius of curvature at one end and a smaller radius of curvature at the opposite end, and/or having a zigzag contour.
It is also to be noted that in spite the rollers described in the above embodiments are stand-alone, they may be alternatively used with additional parts depending on practical requirements. For example, if the rollers are thermo-rollers and too hot to be held with bare hands, the rollers may further include a coupling member at one or both ends thereof so that a handle may be attached to the coupling member of the roller for facilitating a curling operation, and detached from the coupling member after the curling operation has been done.
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
