Specific embodiment
As shown in Figures 2 to 6, this utility model aluminum-plastic copmosite bottle cap includes crown cap 1, aluminum barrel 2, inner cap 3, aluminum barrel 2
In crown cap 1, inner cap 3 is located in aluminum barrel 2.Aluminum barrel 2 top drilling, the top half 33 of inner cap 3 is exposed outside aluminum barrel 2 upwards.
The cannelure 31 of depression is provided with the lateral wall of top half 33, the medial wall of crown cap 1 is provided with prominent chuck 11,
Chuck 11 embeds in cannelure 31, and the two cooperatively forms snap-in structure 5, and this snap-in structure 5 is used for limiting crown cap 1 and inner cap 3
There is upper and lower relative motion in the axial direction along crown cap 1.Above snap-in structure 5, the medial wall of crown cap 1 is additionally provided with arrangement
Ending tendon transfer a12 radially-inwardly stretched out in crown cap 1 circumference and along crown cap 1, the lateral wall of top half 33 of inner cap 3 sets
It is equipped with along inner cap 3 circumference is uniform and ending tendon transfer b32 extending radially out along inner cap 3, ending tendon transfer a12 and ending tendon transfer b32 phase
Mutually be interlocked formation spline structure 6, and this spline structure 6 can limit crown cap 1 and inner cap 3 along the circumferential phase of crown cap 1
To rotation.Above-mentioned spline structure 6 and snap-in structure 5 arrange in the axial direction of crown cap 1, the two position is interchangeable one on the other.
In the present embodiment, ending tendon transfer a12 tri- or three is in groups uniformly at intervals on the circumferencial direction of crown cap 1, and is disposed with 3 groups altogether, in hat
Coordinate with ending tendon transfer b32 on the circumferencial direction of shape lid 1, effectively limit relative turn along the circumferential direction of inner cap 3, crown cap 1
Dynamic it is ensured that bottle cap connect reliability, sealing.The present embodiment only taking 3 groups is as a example said to bottle cap of the present utility model
Bright, 2 groups, 4 groups etc. can also be set to according to real needs in practice, not enumerate herein.
The manufacture method of above-mentioned bottle cap, comprises the steps:
A, on top half 33 lateral wall of inner cap 3, form ending tendon transfer b32 and cannelure 31 respectively, and make ending tendon transfer
B32 is located above cannelure 31；
B, ending tendon transfer a12 that formation is coordinated with ending tendon transfer b32 respectively on the medial wall of crown cap 1, and and cannelure
The chuck 11 of 31 cooperations, cannelure 31 and chuck 11 form snap-in structure 5, and ending tendon transfer b32 and ending tendon transfer a12 form spline structure
6；
C, in aluminum barrel 2 top punching, inner cap 3 is from top to bottom inserted in aluminum barrel 2, and so that the top half 33 of inner cap 3 is revealed
Go out outside aluminum barrel 2；
D, crown cap 1, aluminum barrel 2, inner cap 3 and other Common Components of bottle cap are fitted together, complete bottle cap and make.
Aluminum-plastic copmosite bottle cap of the present utility model, by aluminum barrel 2 top drilling, makes the top half 33 of inner cap 3 expose aluminum barrel 2
Outward, and simultaneously in crown cap 1 and inner cap 3 design spline structure 6 and snap-in structure 5, crown cap 1 is directly passed through with inner cap 3
Snap-in structure 5, spline structure 6 link together, this connect will not temperature influence, be not easy to destroy, thus connect reliable steady
Fixed, be not in the other parts of crown cap 1 and bottle cap, especially detached with inner cap 3 hidden danger is it is ensured that bottle cap quality.And
And, bottle cap of the present utility model, do not need PUR to connect between crown cap 1 and inner cap 3, eliminate the material cost of PUR
Drip the expense of glue with production line, also save the cost serving as a contrast lid in existing bottle cap simultaneously, greatly reduce enterprise's production capacity.With
When, spline structure 6 and snap-in structure 5 ease of assembly it is effectively guaranteed that the reliability that connects between bottle cap component after assembling,
Ensure that bottle cap quality.
Embodiment described above is only preferred implementation of the present utility model to be described, not to this practicality
New scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of this utility model claims determination
In the range of.
