## Background
CROSS REFERENCE OF RELATED APPLICATION
This is a non-provisional application of a provisional application having an application No. 61/216,797 and a filing date of May 20, 2009.


BACKGROUND OF THE PRESENT INVENTION
1. Field of Invention
The present invention relates to a container, and more particularly to a transparent container with image presented.
2. Description of Related Arts
Many liquid or solid containers are decorated by patterns and images on the walls thereof for aesthetic appearance or for indication. For example, water class and wine class are having patterns curved on the outer walls; marks have characters or sentences printed on the outer wall.
All these methods have to work on the wall of the container. Most possibly, the wall is the thinnest and weakest portion of a container. Therefore, any painting, curving, wearing, or other work on the wall cost the risk to break the wall and damage the container. Some treatments can not be performed over the wall, for example, deep curving. And for some treatments, there are many limitations such as the pattern's area and features. Some times, the thickness of the wall has to be increased, or the material of the wall has to be changed. These will introduce high cost, and incontinence of using.
Also, some containers are highly concerned about the aesthetic appearance, such as crystal glass, perfume container, artistic vase, etc. Any marks or labels one the wall will damage the integral appearance.
Compare to the wall, the bottom is always the thickest porting of a container, and consequently, it is much more robust. It can afford different kinds of treatment to achieve a larger range of effects. Also, any marks or labels on the bottom will not be disturbing in appearance. But for conventional containers, the pattern on the bottom is invisible and most of the time is only used for less important indication, such as model number or fabricator. It is a kind of waste that can not utilize the bottom portion to present valuable image and patterns.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 to 3 of the drawings, in a preferred embodiment of the present invention, the container comprises a container body 10 and an image presentation arrangement 20. The container body 10 further comprises a solid base 11 and a surrounding wall 12. The surrounding wall 12 is extending upwardly from the peripheral of the solid base 11 to define a container cavity 13. This cavity provides the containing function of the container.
The solid base 11 of the container is made of transparent material, for example, glass, crystal, plastic, acryl, etc. Preferably, the surrounding wall 12 is made of the same material, but alternatively, the upper portion of the surrounding wall 12 can be made of different material, including opaque material.
The solid base 11 further comprises a bottom concave face 111, a top face 112, and a surrounding face 113. The top face 112 is on the top of the base 11. The bottom concave face 111 is on the bottom of the base 11. The surrounding face 113 is on the out surface of the base 11 and is continuously extending to the surrounding wall 12. The bottom concave face 111 is not a flat plane and is concaved upwardly from the peripheral of the solid base 11. Referring to FIGS. 2 to 4, the peripheral portion of the bottom concave face 111 is inclined upwardly towards the top face 112 and forms the refraction surface 22 of the image presentation arrangement 20. The surrounding face 113 also provides a viewing face 23 thereon. The refraction face 22 and the viewing face 23 define a refraction angle 15. It is easy to see the refraction angle 15 is less than the angle between the surrounding face 113 and the ground level where the container stands. Referring to FIGS. 3 and 4, the contour of the bottom concave face 111 may be different. For example, it could be a curve, or a trapezoid. The contour of the refraction face 22 can be linear, and also can be curved. As shown in FIG. 4, the bottom face 111 of the solid base 11 has a trapezoid shape defining a top flat surface and an inclined flat surface, wherein the image presentation arrangement 20 is formed the inclined flat surface of the bottom face 111 of the solid base 11. The refraction angle 15 is also different for different embodiment. The refraction face 22 and the viewing face 23 can be parallel which means the refraction angle is 0. Compare with a container having a flat bottom, the embodiment of the present invention has a smaller angle between the bottom face and the surrounding face 113 at the edge, and the refraction face 22 on the bottom concave face 111 is closer to the viewing face 23. It is worth mentioning, the top face 112 of the solid base 11 can have different contour, such as flat or curved surface. But the solid base 11 needs to maintain a certain thickness at the peripheral thereof to provide enough area for the viewing face 23.
Referring to FIGS. 1 to 4, the container of the present invention also comprises an image presentation arrangement 20. The image presentation arrangement 20 comprises one or more characters 21 formed on the bottom concave face 111 of the solid base 11, a refraction face 22 formed on the bottom concave face 111, and a viewing face 23 formed on the surrounding face of the solid base 10. Preferably, these image characters 21 are formed on the refraction face 22. The image characters 21 can be formed on the solid base 11 by different methods. For example, the image characters 21 can be formed by embossment, engraving, or enchasing. In a preferred embodiment, the image characters 21 are formed by embossment. The features of the characters 21 are protruded from the solid base. The cross section of the features is rectangular, therefore the refraction and reflection effects of light ray cooperated with the particular material of the container provide a special effect to high light the characters 21. Alternatively, the cross section of the features is triangle, curve, or other shape. In an alternative embodiment, the image characters 21 are painted on the refraction face 22. Different colors are provided.
In order to have a required presentation, the image characters 21 need to be formed in an inversed manner on the refraction face 22. As illustrated in FIG. 5, the left and right of a character are reversed. The sequence of a serial of characters 21 is also left and right reversed. Because the material of the solid base 11 of the container is transparent, the image characters 21 on the refraction face 22 can be seen through the surround wall of the container.
The purpose to have the bottom face concaved and to provide a refraction face 22 is because of the refraction effect. When wave passes from one medium into another of different density, the direction of the wave will change. Because typically the material of the container has a higher density than air, when light ray passes from the material of the container to the air, it will bend away from the normal of the interface. In another word, the light ray in the material of the container is closer to the normal than the ray in the air. As a result, if the bottom of the container is flat, when a user is looking at the bottom of the container from a higher level which happens at most of the time, he will see the image far away from the edge because of the refraction, and the image characters 21 will be squeezed and distorted. The longer distance also reduces the transparency. If the user looks at the bottom of the container at a low level, he can not see any image characters 21 on the bottom. In this situation, because of refraction, the image characters 21 on the peripheral of the bottom can only be seen from a limited range of directions. Look at the container from the most possible directions, the image characters 21 presented on the surrounding face 113 will be distorted and unclear.
Referring to FIG. 3, in the present invention, the refraction face 22 on the bottom concave face 111 lifts the image characters 21 on the bottom closer to the surrounding face 113 of the solid base 11, and the refraction angle 15 is also decreased. Therefore, the image characters 21 on the peripheral portion are easy to be seen from the surrounding face 113, the distortion is also limited.
It is worth mentioning, the solid base 11 of the present invention needs to maintain a predetermined thickness. Therefore, the light ray can pass from the image characters 21 to the surrounding face 113, preferably, to the viewing face 23 directly. If the solid base 11 is not thick enough, the light ray will pass through the solid base 11, then enter into the container cavity 13, then enter into the surrounding wall 12. There will be two more interfaces which will distort and weak the image presentation largely. Because of the refraction face 22, complex characters 21, such as letters can be presented clearly on the viewing face 23, as illustrated in FIG. 3. Alternatively, the thickness of the solid base is limited so the light ray will be refracted by multiple interfaces to get special effects.
It is worth mentioning, the view face 23 of the image presentation arrangement 20 could be a portion of the surrounding face 113 of the solid base 11. The surface of the surrounding face 113 is flat and continuous. The viewing face covers the effective area whereon users and easily see the image presentation from a normal angle. In another word, when a user looks at the container from a range of direction, for example, from 20° to 80° downwardly, the user can see the image presented on the viewing face by refraction.
Alternatively, the viewing face 23 can have different contour from the surrounding face 113. For example, the viewing face may concave or convex from the surrounding face 113 to provide a preferred refraction angle and a preferred image presentation.
The bottom concave face 111 also provides a cavity at the bottom of the container. This cavity can retain a light source or other equipments or features for image presentation improvement. For example, as illustrated in FIG. 4, a plurality of LEDs 24 are provided in the cavity at the bottom of the container. The light ray generated by the LED will provide special effect of the image presentation.
In summary, the present invention doesn't affect the features of the surround wall of the containers. To use the present invention, the shape and surface features of the container will not be changed. It uses the reflection and refraction effects of the light to provide a special effect of presenting designated image characters, such as trade mark, or manufacturer. The user may be attracted by the image presentation to remember the mark to achieve an advertisement result. The invention is low cost, and easy to realize. The selection of available methods to prepare the image characters on the solid base is large. The presentation of the image is flexible and effective.
One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
It will thus be seen that the objects of the present invention have been fully and effectively accomplished. It embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
