Turncap formula fidelity bottle cap described in the utility model is made up of three parts: bottleneck structure, upper and lower cover structure, and core plug structure.

Bottleneck structure is to be made of bottleneck cylinder (25), bottleneck cylindrical center upper end is to be made of circular bottleneck endoporus (22) and conical bottleneck taper hole (24), bottleneck cylinder upper end is outer to be a bottleneck retaining ditch (20) along formation that is a bit larger tham the bottleneck cylinder, plays to lower cover location and anti-back effect.Bottleneck end face (21) is to be evenly distributed on bottleneck endoporus projection on every side by four to constitute, projection is connected with retaining ditch bottom surface, the groove that forms between the projection constitutes four locking grooves (23), and its effect is to core plug assembly location and anti-rotation, with the bottleneck cylindrical sleeve on bottle (26) mouth.

The core plug structure is by core plug (6), plug stifled (11), and cock cap (13) three parts constitute.The core plug is made of a hollow cylinder, and the upper end is a core plug cylinder (32), and the lower end cylinder has one group of patch (7) outward, and the hot pressing of core plug is inserted on the position suitable in bottleneck endoporus and the bottleneck taper hole, and the two interference fit realizes by patch.Plug is stifled to be that the stifled handle (12) of plug that a plug that is made of cylinder blocks up on cylinder (10) and the cylinder is formed, and transition fit is inserted in the top of core consent (5), and by corresponding shoulder stop, the stifled handle of plug is for hand-held firmly its convenient establishing, and is convenient to its plug.Cock cap is to be made of along (14) cylindrical cock cap and cock cap, along following (8) four well-distributeds and the corresponding backing block of bottleneck locking groove (4) are arranged at cock cap, cock cap endoporus (1) and core plug cylinder bearing fit, connect, centering, simultaneously, backing block inserts the bottleneck locking groove on it, and main cock cap lower edge contacts with the bottleneck end face.Cock cap just can not rotate mutually with bottle.The outer below of cock cap cylinder is one six side's gabarit (3) along the place near cock cap.

Lower cover (31) top center is one and the cock cap corresponding hexagonal holes of six side's gabarits (27), the top in lower cover hole is provided with Non-return ring (29), the heating lower cover is to certain temperature, it is enclosed within outside the bottleneck cylinder, its hexagonal hole is enclosed within on six side's gabarits of cock cap, and be pressed on the bottle, to lower cover inner face (18) with cock cap along top applying.At this moment, following tops hexagonal hole is because of being enclosed within on cock cap six side's gabarits, so lower cover and cock cap can not rotate mutually.Simultaneously, the lower cover Non-return ring is because of the effect of bottleneck cambered surface, from downward-sloping upset for being inclined upwardly, and tightly be against in the bottleneck retaining ditch, lower cover hole (30) contacts with bottleneck cylinder bearing fit, and lower cover can not withdraw from mutually with bottle, and straight burr groove (28) is carved with in the lower cover outside.

There are six to connect piece (2) on the intermediate circumference of cock cap, or connect piece (33) with six and be located at cock cap, connect piece by six and connect the upper and lower two parts of cock cap along last.It is narrow and thin to connect piece, forms a weak ring, and before it was not destroyed, plug is stifled can't be extracted from the core consent, promptly can not open bottle, so its function is false proof, and fidelity.

Loam cake (19) is enclosed within on the corresponding cylinder of lower cover and is felt relieved by its loam cake knock hole (16) bearing fit, by its loam cake positioning table (17) stop.And with lock ring (15) with the two pinning, suitably exert oneself just to close or open, like this good seal.Lock ring by the semicircle scrobicular ring that covers down and on semicircle bulge loop two parts of covering constitute.

When needing to open bottle cap, left hand is held bottle portion, and the right hand is pulled up loam cake, holds lower cover straight burr groove section then, and lower cover is rotated in up time or conter clockwise aspect.Because of lower cover through hexagonal hole, cock cap six side's gabarits, and cock cap backing block, the constraint of bottleneck locking groove can not be rotated again, so be sheared disconnected and destroy once weak ring firmly slightly, the fracture top cock cap part of taking away, it is stifled to extract plug, bottle is opened.
