Mouth Opener

It has been found that the conventional mouth opener on the market is too complicated in structure and difficult to operate. Hence, it is desired to have a mouth opener which is simple in construction and easy to use. Further, there is a need for a disposable mouth opener so as to prevent contagion.

Therefore, it is an object of the present invention to provide an improved mouth opener which may obviate and mitigate the above-mentioned drawbacks.

This invention relates to an improved mouth opener.

It is the primary object of the present invention to provide a mouth opener which is easy to operate.

It is another object of the present invention to provide a mouth opener which is simple in construction.

It is still another object of the present invention to provide a mouth opener which may be disposed of after use.

It is still another object of the present invention to provide a mouth opener which is facile to fabricate.

It is a further object of the present invention to provide a mouth opener which is inexpensive in cost.

Other objects and merits and a fuller understanding of the present invention will be obtained by those having ordinary skill in the art when the following detailed description of the preferred embodiment is read in conjunction with the accompanying drawings.

For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alternations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.

With reference to the drawings and in particular to FIGS. 1, 2 and 2A thereof, the mouth opener according to the present invention mainly comprises a substantially Y-shaped body or frame member Y and a twin cup body Z. The Y-shaped body Y is provided with a head handle A and two necks D and D1, while the twin cup body Z has two spaced apart tail troughs or U-shaped members B and B1, two shoulders C and C1, and two bevels E and E1. Further, a belly support wall F with a central recess G is mounted at the intermediate portion of the twin cup body Z. As illustrated, the head handle A associated with the tail troughs B and B1 forms an angle that can produce physical resiliency (see FIG. 5) so that the tail troughs B and B1 will have flexible supporting function between the lower and upper teeth K in the mouth (see FIG. 3) the tail troughs B and B1 being movable relative to each other. The recess of the tail troughs B and B1 is engaged with the clearance between two teeth thereby keeping the the mouth opener in place (see FIGS. 3 and 7). The shoulders C and C1 are disposed between the lips L and the teeth K for providing assistance for the steadiness of the mouth opener. The necks D and D1 are also designed to provide assistance for the steadiness of the mouth opener and to provide the lips with a larger activity space. The tail troughs B and B1 are respectively provided with bevels E and E1 which are inserted between teeth K for ensuring steadiness and fixing of the mouth opener (see FIG. 7). The twin cup body Z has a belly support wall F which is used to reinforce the fixing and support functions. The recess G is compressible and is associated with the resiliency of the material of the jaws Z and the main body Y to reduce the impact of the tail troughs B and B1 on the teeth K when the mouth opener is disposed into the mouth. The Y-shaped body Y is provided with spaced apart concave legs Y1 (see FIG. 4) which acts as a skeleton for strengthening the engagement between the mouth opener and the teeth K.

Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure is made by way of example only and that numerous changes in the detail of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
