Double-walled drinking vessel
Abstract
A double-walled drinking vessel includes a transparent inner
vessel having an outer wall surface formed into a plurality of
circumferentially arranged angles, so that these angles naturally
create a three-dimensional, multi-layered, shinny, and diamond-like
relief in the drinking vessel when seeing from outside of the
drinking vessel, making the double-walled drinking vessel novel and
unique.

Claims
What is claimed is:
1. A double-walled drinking vessel, comprising an outer vessel, a
bottom cover, and an inner vessel; said inner vessel having an
upper open end and a lower closed end, said upper open end of said
inner vessel having an inner diameter larger than that of said
lower closed end, and close to that of an upper rim of said outer
vessel; and an outer wall surface of said inner vessel upward
extended from said lower closed end to a point slightly below said
upper open end being formed into a plurality of circumferentially
arranged angles like a polygon.
2. The double-walled drinking vessel as claimed in claim 1, wherein
an area of said outer wall surface of said inner vessel between any
two of said angles that are adjacent to each other is a curved
surface.
3. The double-walled drinking vessel as claimed in claim 1, wherein
an area of said outer wall surface of said inner vessel between any
two of said angles that are adjacent to each other is a straight
surface.
4. The double-walled drinking vessel as claimed in claim 1, wherein
said circumferentially arranged angles formed on said outer wall
surface of said inner vessel have vertexes located at a common
circle.
5. The double-walled drinking vessel as claimed in claim 1, wherein
said continuous angles formed on said outer wall surface of said
inner vessel have vertexes that are not located at a common circle.
Description
FIELD OF THE INVENTION
[0001] The present invention relates to a double-walled drinking
vessel, and more particularly to a double-walled drinking vessel
having an inner vessel that is formed on an outer wall surface with
a plurality of circumferentially arranged angles, so that a
three-dimensional, multi-layered, shinny, and diamond-like relief
is naturally created in the drinking vessel when seeing from
outside of the drinking vessel.
BACKGROUND OF THE INVENTION
[0002] FIG. 1 is a perspective view of a conventional transparent
double-walled drinking vessel. As shown, the drinking vessel
includes a body 1, and an internal cup 2 formed inside the body 1
to define a closed space 3 between the body 1 and the cup 2. The
closed space 3 is pre-filled with a predetermined type of
refrigerating fluid or refrigerant in the manufacturing process of
the double-walled drinking vessel. To highlight the provision of
the refrigerating fluid or refrigerant in the space 3 between the
two walls of the drinking vessel, the body 1 and the internal cup 2
must be made of a transparent material. The body 1 and the cup 2
are clear and usually have plain surfaces, making the conventional
double-walled drinking vessel monotonous and less attractive in
appearance. It is therefore desirable to develop a novel and unique
double-walled drinking vessel that presents a three-dimensional,
multi-layered, shinny, and diamond-like relief on the vessel.
SUMMARY OF THE INVENTION
[0003] A primary object of the present invention is to provide an
improved transparent double-walled drinking vessel having an inner
vessel that is formed on an outer wall surface with a plurality of
circumferentially arranged angles, so that a three-dimensional,
multi-layered, shinny, and diamond-like relief is naturally created
in the drinking vessel when seeing from outside of the drinking
vessel.
BRIEF DESCRIPTION OF THE DRAWINGS
[0004] The structure and the technical means adopted by the present
invention to achieve the above and other objects can be best
understood by referring to the following detailed description of
the preferred embodiments and the accompanying drawings,
wherein
[0005] FIG. 1 is a perspective view of a conventional double-walled
drinking vessel;
[0006] FIG. 2 is a partially exploded perspective view of a
double-walled drinking vessel according to a preferred embodiment
of the present invention;
[0007] FIG. 3 is an assembled perspective view of FIG. 2;
[0008] FIG. 4 shows a double-walled drinking vessel according to a
second embodiment of the present invention;
[0009] FIG. 5 shows a double-walled drinking vessel according to a
third embodiment of the present invention;
[0010] FIG. 6 shows a double-walled drinking vessel according to a
fourth embodiment of the present invention;
[0011] FIG. 7 shows a closed space formed between inner and outer
walls of the double-walled drinking vessel of the present invention
is filled with a type of refrigerating fluid; and
[0012] FIG. 8 shows the closed space formed between the inner and
outer walls of the double-walled drinking vessel of the present
invention is filled with a type of refrigerant.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] Please refer to FIGS. 2 and 3, in which a double-walled
drinking vessel according to a preferred embodiment of the present
invention is shown. As shown, the double-wall drinking vessel
includes an outer vessel 4, a bottom cover 41, and an inner vessel
5. The inner vessel 5 has an upper open end 51 and a lower closed
end 52. The upper open end 51 of the inner vessel 5 has an inner
diameter larger than that of the lower closed end 52, and close to
that of an upper rim 42 of the outer vessel 4. In the illustrated
preferred embodiment of the present invention, an outer wall
surface of the inner vessel 5 upward extended from the lower closed
end 52 to a point slightly below the upper open end 51 is formed
into a plurality of circumferentially arranged angles 53 like a
polygon, and an area 54 between two adjacent angles 53 is a curved
surface. However, in a second embodiment of the present invention
shown in FIG. 4, the area 54 is a straight surface. In the first
and the second embodiments, vertexes of the angles 53 are located
at a common circle. That is, the vertexes of the angles 53 together
define a circumscribed circle. However, in a third and a fourth
embodiment of the present invention shown in FIGS. 5and 6,
respectively, the angles 53 are not located at a common circle.
Even if the angles 53 are not located at a common circle, the inner
vessel 5 may still be integrally formed along with the outer vessel
4 to produce the double-walled drinking vessel of the present
invention. After the outer and the inner vessel 4, 5 are integrally
formed, it is possible to fill a closed space 6 formed between the
outer and the inner vessel 4, 5 with a predetermined type of
refrigerating fluid, as shown in FIG. 7, or with a predetermined
type of refrigerant, as shown in FIG. 8. Thereafter, an open bottom
of the outer vessel 4 is sealed using the bottom cover 41 to
complete a transparent double-walled drinking vessel.
[0014] To create a beautiful color vision, it is also possible to
particularly form the inner vessel 5 with colored material, so that
the finished drinking vessel presents a completely different visual
effect.
[0015] In addition to the drinking vessel as illustrated in the
accompanying drawings, the present invention may also be
implemented as other types of vessels, such as pitchers, ice cans,
etc.
