Description
FIELD OF THE INVENTION
[0001] The present relates generally to accessory for heat
insulating cup, and specifically, a lid for vacuum insulation
cup.
BACKGROUND OF THE INVENTION
[0002] Stainless steel insulation cup with internal vacuum cavity
has been widely used. Because of its insulation effect, this kind
of insulation cups is popular. However, the lid of the insulation
cup is not insulated by vacuum cavity. As a result, the heat loses
through the lid and the insulating effect of the insulation cup
body is weakened.
SUMMARY OF THE INVENTION
[0003] In order to overcome the aforementioned shortcomings, a
vacuum insulation lid has the same stainless steel vacuum structure
and the same thermal insulation effect as a vacuum insulation cup
body.
[0004] The technical approach of the present invention is: the
vacuum insulation lid comprises stainless steel housing, the
housing has a vacuum cavity, the housing has an evacuation hole on
it, and the evacuation hole has a sealing solder seal block on
it.
[0005] The said housing includes a downwardly opening cover and a
downwardly opening inner cap, the cover and the inner cover are
welded together with an inner cavity is formed between the cover
and the inner cap, and the inner cap is pressed to form an internal
thread.
[0006] The said cover has a pit on its top and the evacuation hole
is located inside the pit.
[0007] The said housing comprises an upper cover and a lower
cylinder which are stamped and formed from stainless steel sheet,
the lower end of the lower cylinder is closed, the outer diameter
of the lower cylinder is smaller than the outer diameter of the
upper cover, the upper cover and the lower cylinder are connected
by welding and the interior of the lower internal cylinder and the
interior of the upper cover form the inner cavity, the side wall of
the lower cylinder is pressed to form an external thread and a
groove, and a waterproof seal ring sets in the groove.
[0008] The advantage of vacuum insulation lid according to the
present invention is better insulation effect. The vacuum insulated
lid of the present invention has a vacuum cavity. As a result, both
the lid and the vacuum insulation cup body have vacuum insulation
effect and the materials in the cup can get a full range of
insulation. At the same time, the insulation lid uses stainless
steel instead of plastic material to avoid the release of the
plastic molecules into the liquid in the cup. Thus, the lid has a
higher level of health standard. The stainless steel structure of
the lid is also stronger and more durable and uniforms the color of
the lid and the cup body.

DETAILED DESCRIPTION OF THE DRAWINGS
EXAMPLE 1
[0017] As FIGS. 1 and 2 show, the vacuum insulation lid comprises
stainless steel housing 10. The housing 10 has a vacuum cavity 11,
the housing 10 has an evacuation hole 12 on it, and the evacuation
hole 12 has a sealing solder seal block 20 on it. That is, the
cavity 11 is vacuumized through the evacuation hole 12 and using
the sealing solder seal block 20 seals the evacuation hole 12.
[0018] More specifically, the housing 10 includes a downwardly
opening outer cover 101 and a downwardly opening inner cap 102. The
outer cover 101 and the inner cover 102 are welded together with an
inner cavity 11 is formed between the outer cover 101 and the inner
cap 102. For instance, the lower edge of the outer cover 101 and
the lower edge of the inner cap 102 are welded together. As such,
the housing 10 forms a double wall sealing structure. The
evacuation hole 12 may be located at the upper end face of the
outer cover 101. And, the inner cap 102 is pressed to form an
internal thread 1021. Clearly, the internal thread 1021 is screwed
on the mouth of a cup and the cup has external threads
essentially.
[0019] Further, the outer cover 101 has a pit 1011 on its top and
the evacuation hole 12 is located inside the pit 1011. This
facilitates the vacuumization operation of the inner cavity 11.
Also, after the vacuumization is completed and the evacuation hole
12 is sealed, the decorative piece may be provided on the pit 1011
to prevent that the evacuation hole 12 is exposed and the sealing
solder seal block 20 is loosed after direct hit, which results the
cavity 11 is not vacuum any more.
[0020] Thus, the vacuum inside the insulation lid improves the
thermal insulation effect of the lid and prevents the more rapid
dissemination of internal heat of the insulation cup.
EXAMPLE 2
[0021] As FIG. 3 and FIG. 4 show, the only difference to Example 1
is: the depth of the inner cylinder 104 is slightly higher, such as
at least 40 mm. Thus, the vacuum insulation lid not only has the
basic function of insulation effect, but also may be used as
insulated container and is not too hot to be held.
EXAMPLE 3
[0022] As FIG. 5 show, the vacuum insulation lid comprises a
stainless steel housing 10. The housing 10 has a vacuum cavity 11,
the housing 10 has an evacuation hole 12 on it, and the evacuation
hole 12 has a sealing solder seal block 20 on it.
[0023] Specifically, the housing 10 comprises an upper cover 103
and a lower cylinder 104 which are stamped and formed from
stainless steel sheet, the lower end of the lower cylinder 104 is
closed, the outer diameter of the lower cylinder 104 is smaller
than the outer diameter of the upper cover 103, the upper cover 103
and the lower cylinder 104 are connected by welding, and the
interior of the lower internal cylinder 104 and the interior of the
upper cover 103 form the inner cavity 11. For instance, the lower
edge of the upper cover 103 and the upper edge of the lower
cylinder 104 are welded together. As such, the evacuation hole 12
may be located at the upper end face of the upper cover 103 or may
be located at the bottom end face of the lower cylinder 104. And,
the lower cylinder 104 is pressed to form an external thread 1041
and a groove 1042. A waterproof seal ring 30 sets in the groove
1042. Clearly, the external thread 1041 is screwed on the mouth of
a cup and the cup has internal threads essentially.
[0024] Thus, the insulation lid becomes an inner lid, so that its
lower cylinder 104 is located in the mouth of a cup and further
increases the thermal insulation effect of the insulation lid. Of
course, the mouth of the cup should have step that the seal ring 30
is tightly pressed against to play the role of waterproof.
[0025] Note that, as shown in FIG. 6, the double wall vacuum
insulation lid as described in Example 2 and the inner plug vacuum
insulated lid as described in Example 3 may not only simultaneously
be applied onto a cup, but also separately be used on a cup. That
is, the inner plug lid is screwed inside the mouth of the cup and
the double wall lid is screwed outside of the cup. Thus, not only
better insulation effect is achieved, but also while the double
wall outer lid is used a container, the inner plug lid still plays
the role of vacuum insulation and the industry technical challenge,
that a cup has no use of plastic parts, is overcome.
