VACUUM INSULATION CUP LID
Abstract
Disclosed is a shank of a four-piece forging of golf club head.
A top piece of the four-piece forging of club head forms, at a
portion thereof adjacent to the shank, a two-staged structure of an
outward flaring sector-shaped connection portion that is combined
with the shank, whereby an abutting condition exhibiting a smooth
surface is formed at a jointing site between the shank and the club
head in the course of performing welding operation between the
shank and the club head for reducing the amount of filling material
used in carrying out the welding operation and making the welding
operation, as well as the subsequent grinding operation, easier and
smoother. Thus, with the quality improved, the flexibility of
design can also be enhanced to reduce the machining time and the
manufacturing costs.

Claims
1. A vacuum insulation cup lid, comprising an outer side wall and
an inner side wall formed integrally on an end face and a side wall
of a circumference thereof, and a vacuum heat-insulated space being
formed between said outer side wall and said inner side wall and
extending completely along the end face and the side wall of the
cup lid and being completely free of substance contained therein,
the inner side wall having an inner diameter on which an internal
thread is formed.
Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to a cup lid having a good
heat insulation function.
DESCRIPTION OF THE PRIOR ART
[0002] A hollow heat-insulated cup is generally known as a thermos
cup; it is used popularly by and welcome among people because it is
heat-insulated and can prevent hands from being burnt. Conventional
heat-insulated cup structures are usually a double layer structure
made of stainless steel, which includes an outer wall and inner
wall, and a heat insulation space is formed between the outer wall
and inner wall, where the heat insulation space is evacuated during
manufacturing, prevent air from becoming a heat conductive medium
between the outer wall and inner wall. A user will not feel hot
while holding a cup on the outer wall even if the cup is filled
with boiled hot water therein because conventional hollow
heat-insulated cup has a very good heat insulation effect.
[0003] Although a cup body of a conventional hollow heat-insulated
cup has a good heat insulation effect, a conventional cup lid
adapted to match with the cup body has been designed without any
structure capable of blocking heat convection until now. Therefore,
heat of water filled in the cup body will usually be conducted to
the cup lid and then dissipated from it such that water temperature
in the cup body cannot maintain long.
SUMMARY OF THE INVENTION
[0004] The object of the present invention is to provide a vacuum
insulation cup lid, allowing a thermos cup to maintain a heat
insulation effect longer.
[0005] The vacuum insulation cup lid of the present invention
adapted to match a cup body of the vacuum insulation cup is further
formed into a hollow heat-insulated structure, allowing the cup
body and cup lid to form a more perfectly heat-insulated structure
after the combination of the cup body and cup lid. Whereby, the
heat of water filled in the cup body cannot be conducted through
the cup body and cup lid directly, and heat dissipation in the cup
body can further be delayed, achieving a longer heat insulation
effect.
[0006] Based on this, the present invention proposes a vacuum
insulation cup lid, formed with an outer side wall and inner side
wall integrated with each other on an end face and the side wall of
the circumference thereof, a vacuum heat-insulated space being
formed between the outer side wall and inner side wall, the inner
diameter of the inner side wall being formed with an inner thread,
and the insulation cup being formed by engaging the inner thread
with an outer thread of a cup body having a similar heat-insulated
function, thereby maintaining water temperature in the cup body
longer.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 is a is a cross-sectional view of a vacuum insulation
cup lid structure of a preferred embodiment according to the
present invention;
[0008] FIG. 2 is an exploded view of a combination correlation
between a cup lid and cup body of a vacuum insulation cup of the
embodiment according to the present invention; and
[0009] FIG. 3 is a cross-sectional view of a vacuum insulation cup
lip and cup body of the embodiment of the present invention after
the combination thereof.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] Referring to FIG. 1, which shows a vacuum insulation cup lid
of a preferred embodiment of the present invention, one end face
and a side wall of the circumference of a cup lid 1 are integrally
formed into a outer side wall 11 and inner side wall 12, where a
heat-insulated space 13 is formed between the outer side wall 11
and inner side wall 12. In addition, an internal thread 14 is
formed on an inner diameter of the inner side wall 12. the
heat-insulated space 13 is a sealed space, evacuated by drawing air
therefrom completely upon the manufacturing of the cup lid,
allowing no medium capable of conducting heat to exist between the
outer side wall 11 and inner side wall 12.
[0011] Referring to FIGS. 2 and 3, which show the combination of
the cup lid 1 and a cup body 2 having a similar heat-insulated
effect, the cup body 2 is a container allowing water, tea or liquid
to be filled therein; it has an inner space extended downward to a
certain depth, and an opening is formed on the upper side of the
inner space, where an external thread 21 matching with the internal
thread 12 mentioned above may be disposed on the outer diameter of
the opening. The cup body 2 has an outer side wall 22 and inner
side wall 23, and a heat-insulated space 24 formed between the
outer side wall 22 and inner side wall 23. Furthermore, the outer
side wall 22 and inner side wall 23 are extended integrally upon
manufacturing, and a distance is kept between outer side wall 22
and inner side wall 23 so as to form a heat-insulated space.
Thereafter, air in the heat-insulated space 24 is drawn out
completely to form a vacuum space so that liquid heat in the
internal space of the cup body 2 can be prevented from dissipating
in a vacuum state that no air medium exists in the heat-insulated
space 24.
[0012] The internal thread 14 of the cup lid 1 being engaged
directly with the external thread 21 of the cup body 2 can prevent
heat in the cup body 2 from being conducted through and dissipated
from the cup body 2 and cup lid 1 through the structures of the cup
lid 1 and cup body 2 mentioned above, thereby achieving a long heat
insulation effect after liquid such as water, tea or drink is
filled in the cup body 2.
[0013] Additional advantages and modifications will readily occur
to those skilled in the art. Therefore, the invention in its
broader aspects is not limited to the specific details and
representative embodiments shown and described herein. Accordingly,
various modifications may be made without departing from the spirit
or scope of the general inventive concept as defined by the
appended claims and their equivalents.
