Anti-fake bottle lid
Technical field
The utility model relates to a kind of bottle cap, relates in particular to a kind of anti-fake bottle lid, belongs to the package packing supplies field.
Background technology
The anti-counterfeiting technology that anti-fake bottle lid adopted of glass bottle in the market, pottery bottle usefulness mainly is to adopt plastic lock catch or metal snap close, comprises enclosing cover and foot circle (or cry twist off ring), and enclosing cover and sufficient the circle install on the glass bottle opening more together with ultrasonic welding again.In the time of need pouring out liquid, twist enclosing cover, enclosing cover is rotated with hand; Bottleneck can not move because foot circle is fixed again, thereby makes the weld seam position of enclosing cover and foot circle be drawn to turn round and disconnect.Owing to can not restore after enclosing cover and foot circle disconnect, thereby reach false proof purpose.Above-mentioned anti-fake bottle lid, though played the effect of ruining lid when opening bottle cap, because glass bottle opening adopts the fixed groove that connects, not only plug slides easily in the bottle cap, and adopts the fixed groove that connects to make bottleneck imitated very easy simply.Therefore be necessary to provide and fixedly fill in the bottle cap better, and be difficult for imitated anti-fake bottle lid.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of anti-fake bottle lid, not only can fixedly fill in the bottle cap better, and make imitation difficulty strengthen.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of anti-fake bottle lid, comprise enclosing cover and the interior plug that is enclosed within on the glass bottle opening, described enclosing cover links to each other by ruining gear ring with Nei Sai, described glass bottle opening is provided with fixed groove, be provided with barb in described beyond the Great Wall and link to each other with fixed groove on the glass bottle opening, wherein, separated in the described fixed groove, gap is formed with slot, is formed with the raised line that is complementary with slot in described beyond the Great Wall and prevents that plug slides in the bottle cap.
Above-mentioned anti-fake bottle lid wherein, is provided with and enclosing cover one bonded assembly circular cylindrical cock body in the middle of the described interior plug, and described circular cylindrical cock body clogs glass bottle opening.
Above-mentioned anti-fake bottle lid, wherein, described enclosing cover and Nei Sai integral molded plastic once-forming.
The utility model contrast prior art has following beneficial effect: the anti-fake bottle lid that the utility model provides, by form interrupted fixed groove at bottleneck, and be formed with slot at gap, not only can be better fixing plug in the bottle cap, and make imitation difficulty strengthen.In addition, by in the middle of interior plug, being provided with and enclosing cover one bonded assembly circular cylindrical cock body, can improve bottle cap ground leak tightness.
Description of drawings
Fig. 1 is the utility model anti-fake bottle lid structural representation;
Fig. 2 is a glass bottle opening structural representation of the present utility model.
Among the figure:
1 fixed groove 2 is ruined gear ring 3 enclosing covers
Plug 5 slots 6 circular cylindrical cock bodys in 4
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is the utility model anti-fake bottle lid structural representation; Fig. 2 is a glass bottle opening structural representation of the present utility model.
See also Fig. 1 and Fig. 2, the anti-fake bottle lid that the utility model provides comprises enclosing cover 3 and the interior plug 4 that is enclosed within on the glass bottle opening, described enclosing cover 3 links to each other by ruining gear ring 2 with Nei Sai 4, described glass bottle opening is provided with fixed groove 1, plug 4 is provided with barb and links to each other with fixed groove 1 on the glass bottle opening in described, and is wherein, separated in the described fixed groove 1, gap is formed with slot 5, is formed with the raised line that is complementary with slot 5 on the described interior plug 4 and prevents that plug slides in the bottle cap.
The anti-fake bottle lid that the utility model provides by forming interrupted fixed groove 1 at bottleneck, and is formed with slot 5 at gap, not only can be better fixing plug 4 in the bottle cap, and make imitation difficulty strengthen.
In addition, shortcoming at existing anti-fake bottle stopper leak tightness difference, the utility model can further be provided with and enclosing cover one bonded assembly circular cylindrical cock body 6 in the middle of interior plug 4, described circular cylindrical cock body 6 clogs glass bottle opening, the enclosing cover of outwarding winding is real extracts circular cylindrical cock body 6, thereby has improved the anti-fake bottle stopper leak tightness.
Existing anti-fake bottle lid generally adopts the split injection mo(u)lding, and then assembles, and has not only increased the stack-mounted cost of labor, and feasible imitated easier, the anti-fake bottle lid that the utility model provides, and enclosing cover 1 and Nei Sai 4 can adopt the integral molded plastic once-forming.In addition, existing anti-fake bottle lid generally adopts the PET plastics, and anti-fake bottle lid of the present utility model can adopt the PPT plastics.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
