Description
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 11, 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 bottle body 1. 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 31 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 1 to 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.
