Heat-isolating container
Abstract
A container includes a containing main body, and a
heat-isolating part positioned around and secured to the containing
main body; the heat-isolating part has several spaced apart
outwardly-protruding heat-isolating portions, and several
inwardly-protruding coupling portions, which are between the
outwardly-protruding heat-isolating portions; the heat-isolating
part are secured on an outer circumferential side of the containing
main body at the inwardly-protruding coupling portions thereof with
heat-isolating spaces existing between the containing main body and
the outwardly-protruding heat-isolating portions; thus, when a hot
drink is contained in the containing main body, high-temperature
heat of the hot drink will travel outwards through the containing
main body to be absorbed by the air in the heat-isolating spaces,
and the hot air will travel outside from the heat-isolating
spaces.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the invention
[0002] The present invention relates to an improvement on a
heat-isolating container, more particularly one, which includes a
containing main body, and a heat-isolating part secured around the
containing main body, and several heat-isolating spaces between the
containing main body and the heat-isolating part for preventing the
high-temperature heat of a hot drink from rapidly traveling to the
heat-isolating part, thus protecting the user's hands.
[0003] 2. Brief Description of the Prior Art
[0004] Cups are usually made of pottery, porcelain, plastics, metal
or paper. Although the above-mentioned materials have a certain
heat-isolating capability, the outer sides of common cups will
become hot in a relatively short length of time after a
hot-drink/food is put in the cups. Consequently, the user can't
continue holding the cups for a longer period of time.
[0005] Takeaway and convenient stores provide much convenience to
people, especially working people and those who have to eat
outside. In order not to make customers behind them wait too long,
people usually don't have drinks and foods packaged, and take them
away with bare hands at a takeaway/convenient store immediately
after they pay. Their hands will be subjected to high temperature
if the foods and drinks are very hot.
[0006] A kind of heat-isolating paper cup is available, which
includes a main containing part, and an outer enclosing part; the
main containing part has an upper opening; the outer enclosing part
is positioned around the main containing part, and it has a
corrugated surface. The area of contact between the cup and the
user's hand is relatively small because of the corrugated surface
of the outer enclosing part. Therefore, the user's hands will be
subjected to less heat when holding the paper cup containing a hot
drink. However, the user still will feel uncomfortable high
temperature after holding the cup for a longer length of time.
SUMMARY OF THE INVENTION
[0007] It is a main object of the invention to provide an
improvement on a heat-isolating container to overcome the
above-mentioned problems.
[0008] The heat-isolating container of the present invention
includes a containing main body, and a heat-isolating part
positioned around and secured to the containing main body. The
heat-isolating part has several spaced apart outwardly-protruding
heat-isolating portions, and several inwardly-protruding coupling
portions between the outwardly-protruding heat-isolating portions.
The inwardly-protruding coupling portions of the heat-isolating
part are joined to an outer circumferential side of the containing
main body with heat-isolating spaces existing between the
containing main body and the outwardly-protruding heat-isolating
portions. Consequently, when a hot drink is contained in the
containing main body, high-temperature heat of the hot drink will
travel outwards through the containing main body to be absorbed by
the air in the heat-isolating spaces, and the hot air will travel
outside from the heat-isolating spaces, preventing the user's hands
from being subjected to high temperature.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The present invention will be better understood by referring
to the accompanying drawings, wherein:
[0010] FIG. 1 is an exploded perspective view of the present
invention,
[0011] FIG. 2 is a lateral sectional view of the present
invention,
[0012] FIG. 3 is a top view of the present invention,
[0013] FIG. 4 is an exploded perspective view of the second

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] Referring to FIGS. 1 to 3, a first preferred embodiment of a
heat-isolating container 1 includes a containing main body 11, and
a heat-isolating part 12, both of which can be made of paper. The
containing main body 11 has a sealed lower end, and has an opening
at an upper end thereof. The heat-isolating part 12 is positioned
around the containing main body 11.
[0016] The heat-isolating part 12 has several spaced apart
outwardly-protruding heat-isolating portions 121, and several
inwardly-protruding coupling portions 122, each of which folds with
a line-shape, and each of which is between two adjacent ones of the
outwardly-protruding heat-isolating portions 121. Furthermore, the
heat-isolating part 12 has a smooth connecting portion 123 at a
lower end. The heat-isolating part 12 is positioned around and
stuck to the containing main body 11 by means of sticky substance
applied between an outer circumferential side of a lower end of the
containing main body 11 and the connecting portion 123 of the
heat-isolating part 12 as well as between an outer side of the
containing main body 11 and each of the inwardly-protruding
coupling portions 122; thus, the area of contact between the
containing main body 11 and each inwardly-protruding coupling
portion 122 has a line-shape, and heat-isolating spaces 13 exist
between the containing main body 11 and the heat-isolating portions
121 of the heat-isolating part 12, each of which heat-isolating
spaces 13 has a through hole 131 at an upper end thereof.
[0017] When a hot drink/food is contained in the containing main
body 11, high-temperature heat of the hot drink/food will travel
outwards through the containing main body 11 to be absorbed by the
air in the heat-isolating spaces 13, and the hot air in the
heat-isolating spaces 13 will travel outside through the through
holes 131 of the heat-isolating spaces 13. And, because the area of
contact between the containing main body 11 and each
inwardly-protruding coupling portion 122 is in the shape of a line,
the area of contact between the inwardly-protruding coupling
portions 122 and the containing main body 11 is relatively small.
Consequently, heat will travel to the heat-isolating part 12 at a
relatively low speed, and a person won't be subjected to high
temperature when holding the container 1.
[0018] FIGS. 4 and 5 show a second preferred embodiment of a
heat-isolating container in the present invention, which includes a
containing main body 11, and a heat-isolating part 12' positioned
around the containing main body 11. The heat-isolating part 12' has
several spaced apart outwardly-protruding heat-isolating portions
121', and several inwardly-protruding coupling portions 122', each
of which folds with a line-shape, and each of which is between two
adjacent ones of the outwardly-protruding heat-isolating portions
121'. The heat-isolating part 12' is positioned around and securely
joined to the containing main body 11 with the inwardly-protruding
coupling portions 122' touching an outer side of the containing
main body 11; thus, the area of contact between the containing main
body 11 and each inwardly-protruding coupling portion 122' has a
line-shape, and heat-isolating spaces 13' exist between the
containing main body 11 and the heat-isolating portions 121' of the
heat-isolating part 12, each of which heat-isolating spaces 13' has
an upper through holes 131' at an upper end, and a lower though
hole 132' at a lower end thereof.
[0019] When a hot drink/food is contained in the containing main
body 11, high-temperature heat of the hot drink/food will travel
outwards through the containing main body 11 to be absorbed by the
air in the heat-isolating spaces 13', and the hot air in the
heat-isolating spaces 13' will travel outside through the upper
through holes 131', and cool air into the heat-isolating spaces 13'
through the lower through holes 132' by convection. Consequently,
heat in the heat-isolating spaces 13' will be more rapidly
dissipated owing to convection.
[0020] From the above description, it can be seen that the present
invention has the following advantages:
[0021] 1. Because heat-isolating spaces with upper through holes
exist between the containing main body and the heat-isolating part,
air will absorb and dissipate the high-temperature heat of a hot
drink/food when the hot drink/food is contained in the containing
main body. Consequently, a person won't be subjected to
high-temperature heat when holding such a container containing a
hot drink/food.
[0022] 2. Because heat-isolating spaces with upper and lower
through holes exist between the containing main body and the
heat-isolating part, air in the heat-isolating spaces will absorb
and dissipate the high-temperature heat of a hot drink/food by
convection when the hot drink/food is contained in the containing
main body. Consequently, heat will be rapidly dissipated.
[0023] 3. Because the inwardly-protruding coupling portions of the
heat-isolating part fold to have a line-shape, the area of contact
between the inwardly-protruding coupling portions of the
heat-isolating part and the containing main body is relatively
small.
