Preferentially, including two sliding blocks, total two through-holes are symmetrically opened up on the bottle cap lateral wall, it is each described logical The sliding block that is slidably connected is sealed in hole respectively, two sliding blocks are located on the outside of two extension boards.

Preferentially, the extension board shape is L shape.

Preferentially, the block shape is triangular prism.

Preferentially, the sliding block inner end cutting is tapered.

Preferentially, several described contact pin lower ends cut into sharp cone distal.

The utility model it is achieved the utility model has the advantages that

The present apparatus scratches openning by extension board realization on sealed membrane, is realized by promoting slider and is adjusted on sealed membrane The diameter of opening, it is ingenious in design；It is slidably connected bottle cap by sliding block sealing, avoids after opening screws on bottle cap beverage from through-hole Outflow.

Detailed description of the invention

Fig. 1 is the vertical profile figure of the present apparatus.

Mark meaning in attached drawing, 1- bottle cap；2- bottle body；3- extension board；4- block；5- sliding block；6- contact pin；7- through-hole；8-L Shape slot；9- sealed membrane.

Specific embodiment

The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.

A kind of bottle cap of adjustable openings diameter, including bottle cap 1 open up the circle of cooperation bottle body 2 on 1 bottom surface of bottle cap Cylindricality holding tank, internal screw thread is opened up on the cylindrical reception groove inner sidewall, and 2 upper end of bottle body opens up the outer of the cooperation internal screw thread Screw thread；Further include two extension boards, 3, two blocks 4 and several contact pins 6, is symmetrically opened up in the 1 inner sidewall middle-end of bottle cap The L-shaped groove 8 of total two cooperations extension board 3,1 bottom wall of bottle cap open up total two upwards and are respectively communicated with described in one 1 bottom wall of bottle cap, two institutes are stretched out in the long through-hole of L-shaped groove 8, two 3 lower ends of extension board from the long through-hole respectively It states 3 lower end of extension board and is respectively fixedly connected with the block 4, two 3 upper ends of extension board extend to 9 top of sealed membrane, Several described contact pins 6 are respectively fixedly connected with the 3 upper end lower surface of extension board, and there are gaps apart from bottleneck for extension board 3, are convenient for The size for the opening that adjustment extension board 3 opens up on sealed membrane.

Further, including two sliding blocks 5, total two through-holes 7 are symmetrically opened up on 1 lateral wall of bottle cap, each The sliding block 5 that is slidably connected is sealed in the through-hole 7 respectively, two sliding blocks 5 are located at two extension boards 3 Outside, L-shaped groove 8 are curved to the inside deformation during compressing extension board 3 convenient for sliding block 5, and the bending for not influencing 3 upper end of extension board becomes Shape.

Further, 3 shape of extension board is L shape, and extension board 3 is with elastically-deformable plate.

Further, 4 shape of block is triangular prism, and triangular prism tip is outside, is pressed on block 4 convenient for user's finger Above to easily depress extension board.

Further, 5 inner end of the sliding block cutting is tapered.

Further, several described 6 lower ends of contact pin cut into sharp cone distal.

In the initial state, two 3 upper ends of extension board are located at sealed membrane upper end and use hand when user needs to open bottle cap Refer to the outer end for pressing down on the block 4, so that contact pin 6 has opened an osculum on sealed membrane 9, it can be by inwardly promoting cunning The sliding block 5 that block 5 is is pressed on the outside of 3 upper end of extension board, and sliding block 5 inwardly promotes 3 upper end of extension board so as to adjust extension board 3 The size of the opening diameter opened up on sealed membrane 9, ingenious in design, Unscrew bottle cap contact pin is followed by bottle cap rotation, will seal Membrana oralis scratches two arc-shaped openings, and the circular arc size for the opening specifically scratched can be according to the depth and bottle cap that contact pin 8 is inserted into The lifting heights design that turns around is revolved, can design after contact pin 8 follows bottle cap to rotate 45 degree to 175 degree degree and leave plastic foil sealing part So that plastic foil sealing is upper, there are two arc-shaped openings, so that the plastic foil that the plastic foil scratched still connects edge prevents from moulding Material film 11 is called in beverage bottle, and the use feeling of user is improved, and user can choose whether according to itself hobby along arc-shaped Be open sealed membrane central privately；Sliding block 5 sealing be slidably connected through-hole 7 avoid sealed membrane open rear cover upper bottle cover after beverage from It is flowed out in through-hole 7.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change It also should be regarded as the protection scope of the utility model into deformation.
