Specific embodiment
In order that the object, technical solutions and advantages of the present invention become more apparent, it is right with reference to embodiment and accompanying drawing
The present invention is further described.
Embodiment 1：
Shown in reference picture 1-6, lid of the invention, including inner cap 2 and rotate the enclosing cover 1 that is connected with inner cap 2.Inner cap 2 sets
The opening of insertion is equipped with, enclosing cover 1 includes the roof 101 for closing opening, and the medial surface of roof 101 is provided with cyclic lug
105, when enclosing cover 1 is covered on inner cap 2, cyclic lug 105 forms interference fit with the inwall of inner cap 2.When using, inner cap 2
It is installed on container, afterwards, can be specifically caused by rotating enclosing cover 1 using modes such as threaded connection or interference fits
Enclosing cover 1 is covered in the opening of inner cap 2, and now, enclosing cover 1 forms interference fit by cyclic lug 105 with inner cap 2, so as to protect
Sealing property between card enclosing cover 1 and inner cap 2.
As shown in FIG., enclosing cover 1 also includes the side wall 102 connected with roof 101, and side wall 102 is located at cyclic lug 105
Outside, annular breach 201 is offered on the lateral surface of inner cap 2, when enclosing cover 1 is covered on inner cap 2, side wall 102 is at least part of
It is coated on annular breach 201.So, when enclosing cover 1 is covered, the side wall 102 of enclosing cover 1 is in same circle with the side wall 102 of inner cap 2
On side face.
In the present invention, further, enclosing cover 1 is closed by clamping with inner cap 2, so, is easy to use.Preferably, side
It is provided with wall 102 and pulls to open the radially protruding part 103 of enclosing cover 1 for staff.When using, can be by pulling this radially
Protuberance 103 applies active force to enclosing cover 1, so that it is opened relative to inner cap 2.
To prevent enclosing cover 1 from arbitrarily being opened, lid of the invention also includes hand sheet 6, is provided with along enclosing cover on side wall 102
1 banking stop 104 for extending radially outwardly, hand sheet 6 is connected and spacing by banking stop 104 with inner cap 2.The banking stop 104
Opponent's sheet 6 produces stop, the i.e. part of hand sheet 6 to be located on banking stop 104, and it has two legs, and two legs are by spacing
The both sides of piece 104 pass through and are connected with inner cap 2 respectively.Only when the hand sheet 6 is torn, enclosing cover 1 can be just opened.The knot
Structure can also using other alternative solutions, as long as enclosing cover 1 and inner cap 2 can be produced into position restriction in the early stage, prevent by with
Meaning is opened.
Enclosing cover 1 is connected and can be realized by the way of bearing pin with the rotation of inner cap 2, and in the present invention, enclosing cover 1 and inner cap 2
Between connected by connection sheet 5, be formed with connection sheet 5 for enclosing cover 1 relative to the folding line that inner cap 2 is rotated.Opened or closed when beating
When closing enclosing cover 1, enclosing cover 1 is rotated around the folding line.This mode, butterfly is constituted by forming connection sheet creasy 5
Hinge, is easy to enclosing cover 1 to produce elasticity to stir relative to inner cap 2, is easy to use.
In the present invention, enclosing cover 1, inner cap 2 and connection sheet 5 are structure as a whole, this mode, are easy to processing.
Preferably, lid of the invention also includes spoon 4, and spoon 4 is connected with the inwall of inner cap 2, and can be in outer masterpiece
Torn by inner cap 2 under.That is, spoon 4 and the only part contact of inner cap 2, when user somewhat exerts oneself, you can by spoon
4 remove from inner cap 2.
Preferably, the medial surface of roof 101 is provided with two relative snap-latch pieces 3, phase is respectively arranged with snap-latch piece 3
To spacing preiection, spoon 4 can be snapped between two snap-latch pieces 3.So, after spoon 4 is removed, snap-latch piece can be positioned over
Between 3, and carried out by spacing preiection spacing, it is to avoid it is dropped out.
In the present invention, spoon 4 has handle portion 401 and spoon portion 402, and handle portion 401 is provided near the one end in spoonful portion 402
Through hole 403, spoon portion 402 is by near one end of handle portion 401 to the arc being gradually reduced away from one end height dimension of handle portion 401
Shape.This mode, the position connected with spoon portion 402 in handle portion 401 sets through hole 403, when in use, especially contains milk powder
When, milk powder can be avoided to be adhered on spoon.Additionally, spoon portion 402 is set to arc, its end (away from one end of handle portion) compared with
It is shallow, so, it is easy to incline, it is easy to use.
Lid can select to be metal, plastics or other conventional materials that the lid material of the present embodiment 1 is PP trees
Fat.

As can be seen from Table 3, the present invention is turned white titanium dioxide TiO in agent using resistance to stress2, tin ash SnO2And dioxy
Change zirconium ZrO2Three compounds, and is arbitrarily compounded two-by-two relative to it, and stress-whitening resistance can be increased dramatically, Synergistic, produces
Unexpected technique effect is given birth to.
General principle of the invention and principal character and advantages of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not limited to the above embodiments, simply explanation described in above-described embodiment and specification this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appending claims and its
