Description

THERMOS HAVING MULTIPLE HERMETICAL HEAT
PRESERVATION STRUCTURES AND GLASS LINER EASY TO
DISASSEMBLE AND ASSEMBLE
TECHNICAL FIELD
[0001] The present invention relates to the technical field of thermos, in
particular to a
thermos having multiple hermetical heat preservation structures and a glass
liner easy to
disassemble and assemble.
BACKGROUND
[0002] Thermos on the current market mainly comprise bottle bodies and bottle
caps. By
threaded connection between the bottle body and the bottle cap, a hermetical
heat preservation
space is formed. Existing thermos are irregular in quality, and usually cannot
achieve a heat
preservation effect. Heat in the bottle bodies is lost too fast, and problems
such as poor
airtightness, etc., exist. Secondly, in order to enhance the heat preservation
property of traditional
thermos, inner and outer walls of the bottle bodies are connected by welding.
While in actual use,
once the inner walls are damaged, the thermos lose the heat preservation
property, and the
thermos cannot continue to be used by replacing the inner walls. For this
purpose, there is a need
of a thermos which is better in airtightness, better in heat preservation
property and more reliable
and has a replaceable or removable glass liner.
SUMMARY
[0003] Objects of the present invention are to overcome defects of the prior
art and to
provide a thermos having multiple hermetical heat preservation structures and
a glass liner
easy to disassemble and assemble.
[0004] In order to realize the above objects, the present invention provides a
thermos having
multiple hermetical heat preservation structures and a glass liner easy to
disassemble and
assemble. The thermos comprises a bottle cap, a fixing cap, a water seal
piece, a seal ring,
the glass liner and a bottle body. External bottle body opening threads and
internal bottle
body opening threads are respectively molded on the outer side surface and the
inner side
surface of a bottle opening of the bottle body, wherein the external bottle
body opening
threads and the internal bottle body opening threads are respectively in
thread fit with bottle
cap threads molded on an inner side surface of the bottle cap and glass liner
threads molded
on an outer side surface of the glass liner. The seal ring sleeves the outer
side surface of the
glass liner, wherein when the bottle body and the glass liner are connected in
a matching
manner, a lower surface of the seal ring makes contact with a bottle opening
edge of the
bottle body. The fixing cap and an inner top of the bottle cap are connected
in a matching
manner. The water seal piece sleeves the fixing cap, wherein when the bottle
body and the
bottle cap are connected in a matching manner, the water seal piece and a
bottle opening of
the glass liner are matched hermetically.
[0005] Further, a fixing boss is formed on the inner top of the bottle cap,
and the fixing
boss is connected with a fixing clamping groove formed in the fixing cap in a
matching
manner.
[0006] Further, a plurality of raised ribs is molded on an outer side surface
of the water seal

piece.
[0007] Further, an inverted buckle matched with the top end of the fixing cap
is molded on an
inner side surface of the water seal piece.
[0008] Further, a vacuum hollow interlayer is disposed in the bottle body.
[0009] The present invention adopts the above solution and has the following
beneficial effects.
A thermos hermetical structure is formed by the bottle cap, the fixing cap,
the water seal piece,
the seal ring, the glass liner and the bottle body. The glass liner and the
bottle body are connected
and fixed by the threads. By compressing the seal ring vertically, easiness in
replacement of the
glass liner and a hermetical effect between the glass liner and the bottle
body are realized. The
.. bottle opening of the glass liner and the water seal piece cooperate with
each other, thereby
achieving water leakage preventing and hermetical effects. Meanwhile, by
matching and
connection among the bottle cap, the fixing cap and the water seal piece as
well as the vacuum
hollow interlayer of the bottle body, heat exchange between heat in the glass
liner and external air
is isolated. A heat preservation property of the thermos is further improved.
Secondly, the glass
liner has the characteristics of easiness in replacement and removal.
Therefore, the thermos is
enabled to be more durable, and the bottle body can be directly used by
removing the glass liner.

.. DETAILED DESCRIPTION
[0022] The present invention is further explained in combination with specific
embodiments.
[0023] Referring to Figs. 1 to II,in the present embodiment, a thermos having
multiple
hermetical heat preservation structures and a glass liner easy to disassemble
and assemble
comprises a bottle cap 2, a fixing cap 5, a water seal piece 6, a seal ring 4,
a glass liner 3 and a
2

bottle body I . External bottle body opening threads 11 and internal bottle
body opening threads
12 are respectively molded on the outer side surface and the inner side
surface of a bottle opening
of the bottle body 1, wherein the external bottle body opening threads 11 and
the internal bottle
body opening threads 12 are respectively in thread fit with bottle cap threads
22 molded on an
inner side surface of the bottle cap 2 and glass liner threads 3 I molded on
an outer side surface of
the glass liner 3. The seal ring 4 sleeves the outer side surface of the glass
liner 3, wherein when
the bottle body 1 and the glass liner 3 are in threaded connection, a lower
edge surface of the seal
ring 4 makes contact with an opening edge of the bottle body 1, and a
hermetical effect is
achieved by compressing the seal ring 4 vertically through the bottle body 1
and the glass liner 3.
A fixing boss 21 is formed on the inner top of the bottle cap 2. The fixing
cap 5 is provided with a
fixing clamping groove 51 matched with the fixing boss 21. The water seal
piece 6 sleeves the
fixing cap 5, wherein an inverted buckle 62 matched with the top end of the
fixing cap 5 is
molded on an inner side surface of the water seal piece 6. By disposing the
inverted buckle 62,
the water seal piece 6 can be more firmly connected to the fixing cap 5. A
condition that the
airtightness becomes poor caused by falling of the water seal piece 6 is
avoided. A plurality of
raised ribs 61 is molded on an outer side surface of the water seal piece 6.
After the bottle body 1
and the bottle cap 2 are connected in a matching manner, the water seal piece
6 and the inner side
surface of the glass liner 3 are matched. The water seal piece 6 prevents
water leakage and
achieves a hermetical effect with the glass liner 3. The plurality of raised
ribs 61 is disposed to
make contact with the inner side surface of the bottle opening of the glass
liner 3. Therefore, the
airtightness between the water seal piece 6 and the glass liner 3 is further
enhanced. A hollow
interlayer is disposed in the bottle body 1. When the glass liner 3 is placed
in the bottle body 1,
the heat of liquid in the glass liner 3 conduced out of the bottle body 1 via
the bottle body Ito be
subjected to heat exchange with air is reduced. Therefore, heat loss is
reduced. By formation and
cooperative use of the above components, the thermos has multiple hermetical
heat preservation
structures. Therefore, the heat preservation property, reliability and
airtightness of the thermos are
further improved. Secondly, due to the characteristic of easiness in
disassembly and assembly of
the glass liner 3, the thermos has the characteristic of a replaceable or
removable glass liner 3.
Further, the thermos is enabled to be more durable. Meanwhile, when the glass
liner 3 is damaged
but not replaced yet or the glass liner 3 is not used according to the needs,
the bottle body 1 can
be directly used by removing the glass liner 3.
[0024] The foregoing embodiments are merely preferable embodiments of the
present
invention, and are not intended to define the present invention in any form.
Any person skilled in
the art can make more possible changes or modifications to the technical
solution of the present
invention or modify into equivalent embodiments of the present invention by
using the technical
content disclosed above without departing from the scope of the technical
solution of the present
invention. Thus, the content not departing from the technical solution of the
present invention and
identical and equivalent changes made according to a concept of the present
invention all fall
within a protective scope of the present invention,
