DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0024] Advantages and features of the inventive concept and methods
of accomplishing the same may be understood more readily by
reference to the following detailed description of embodiments and
the accompanying drawings. The inventive concept may, however, be
embodied in many different forms and should not be construed as
being limited to the embodiments set forth herein. In the drawings,
the relative sizes of elements should not be construed as being
limited to the proportion and arrangement relationship as shown in
the drawings and may be exaggerated for clarity, without departing
from the spirit and scope of the present invention.
[0025] FIG. 2 is a first schematic view of an assembled cup
structure in accordance with a first embodiment of the present
invention. FIG. 3 is a second schematic view of the assembled cup
structure in accordance with a first embodiment of the present
invention. FIG. 4 is a third schematic view of the assembled cup
structure in accordance with a first embodiment of the present
invention. FIG. 5 is a first schematic view of the assembled cup
structure in accordance with a second embodiment of the present
invention. FIG. 6 is a second schematic view of the assembled cup
structure in accordance with the second embodiment of the present
invention. One of the features of the present invention is that the
assembled cup structure is a dual-layer structure. One cup body can
be stacked and disposed in the other cup body easily. When in use,
the user just holds the outer cup body. A beverage is filled in the
inner cup body. Through the space between the two cup bodies, the
present invention provides a better thermal insulation effect,
preventing the filled beverage from scalding the user. Another
feature of the present invention is that portions of the two cup
bodies are attached to each other closely, such that the beverage
won't flow to the space between the two cup bodies when the
beverage in the inner cup body is spilt.
[0026] In detail, as shown in FIG. 2 to FIG. 6, the assembled cup
structure of the present invention comprises an outer cup body 10
and an inner cup body 20. The outer cup body 10 is formed with a
first curved portion 12 on an inner wall thereof close to an outer
cup mouth 11. An end edge of an inner cup mouth 21 of the inner cup
body 20 is formed with a contact portion 22. The contact portion 22
holds against the first curved portion 12 of the outer cup body 10.
Thereby, the inner cup body 20 is disposed inside the outer cup
body 10. A space is defined between the bottom of the inner cup
body 20 and the bottom of the outer cup body 10. Preferably, the
distance A from the position where the first curved portion 12 and
the contact portion 22 contact with each other to the outer cup
mouth 11 of the outer cup body 10 is 11 mm to 16 mm. When the user
drinks the beverage, he/she can feel the temperature of the
beverage with his/her lips, avoiding the beverage from scalding the
lips, but not limited thereto.
[0027] In the first embodiment, the first curved portion 12 of the
outer cup body 10 may be a stepped configuration. As shown in FIG.
3 and FIG. 4, the stepped configuration includes a stepped surface
121 which may be concave or flat. The contact surface 22 of the
inner cup body 20 may be held on the stepped surface 121. In a
second embodiment, the first curved portion 12 may be an annular
groove, as shown in FIG. 5 and FIG. 6. The inner cup body 20 is
retained in the outer cup body 10 through the first curved portion
12 in the form of an annular groove to engage with the contact
portion 22.
[0028] Furthermore, the outer cup body 10 is formed with a first
mating portion 13 beneath the first curved portion 12. The inner
cup body 20 is formed with a second mating portion 23 on an outer
wall thereof beneath the contact portion 22. The second mating
portion 23 is attached to the first mating portion 13 of the outer
cup body 10 closely. This design can avoid the filled beverage from
spilling and flowing to the space between the inner cup body 20 and
the outer cup body 10. The first mating portion 13 and the second
mating portion 23 may be bevels having a same slope. Preferably,
the mating length C of the first mating portion 13 and the second
mating portion 23 is 1 mm to 4 mm, but not limited thereto.
[0029] Besides, the outer cup body 10 is further formed with a
second curved portion 14 beneath the first mating portion 13. The
inner cup body 20 is formed with a buckle portion 24 beneath the
second mating portion 23. The buckle portion 24 leans against the
second curved portion 14. Thereby, the retaining strength between
the inner cup body 20 and the outer cup body 10 can be enhanced,
avoiding the inner cup body 20 from slipping out of the outer cup
body 10. Preferably, the distance B from the position wherein the
first curved portion 12 and the contact portion 22 contact with
each other to another position where the buckle portion 24 and the
second curved portion 14 engage with each other is less than 10 mm.
This is beneficial to increase the strength of the outer cup body
10 and the inner cup body 20 when in use, but not limited
thereto.
[0030] Preferably, the outer cup body 10 and the inner cup body 20
of the assembled cup structure of the present invention may be made
of plastic, paper or a foam material. Preferably, the outer cup
body 10 and the inner cup body 20 may be made of a transparent
material or a colored material. Furthermore, the bottom of the
outer cup body 10 may be formed an aperture 15. The aperture 15 is
adapted to exhaust the vapor generated between the outer cup body
and the inner body due to heat, so that the pressure between the
inner cup body and the outer cup body can be balanced, avoiding the
cup bodies from being buckled and deformed.
[0031] Although particular embodiments of the present invention
have been described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the present invention. Accordingly, the
present invention is not to be limited except as by the appended
claims.
