Cooperate Fig. 7, has a reference surface 44 round central axis setting in the above-mentioned spiral shell rotary head 422, and five from this reference surface 44 radially outstanding the and helical protrusion bar 45 that changes of spiral shell to the right, each helical protrusion bar 45 all has the end face 451 of a level, one and end face bottom surface spaced 452 about in the of 451, and one be engaged on the top, bottom surface 451,452 helical surface 453, above-mentioned helical surface 453 is the updip sections 454 that enlarge gradually from top to bottom by, one enlarges the section of having a down dip 455 from lower to upper gradually, and be positioned at two sections of inclining 454, a separation line 456 of 455 is formed, and constitutes the prominent bar 45 of multi-thread multi-section tapered screw whereby.The structure of these two sections bevel-type gradual change diameters can be clearer by the explanation of following size.

The present embodiment actual size in design, the imaginary diameter D3 of 451 corrals of end face of each helical protrusion bar 45 is 11.75mm, the imaginary diameter D4 of 452 corrals in bottom surface of each helical protrusion bar 45 is 10.5mm, and the imaginary diameter D5 of 456 corrals of separation line of each helical protrusion bar 45 is 12mm.And obturating plug 3 is in the design of size, the spiral shell rotary head 422 of the size of the holding part 303 in this control hole 34 and control seat 4 fits like a glove, and just imaginary aperture D12, D11, the D13 with the bottom of trench institute corral of each spiral guide channel 302 is respectively 11.75mm, 12mm, 10.5mm in holding part 303.But the undersized of the bulge 304 in control hole 34 is in this spiral shell rotary head 422, and actual size design is that top imagination aperture D21 is 10.5mm, and bottom imagination aperture D22 is 11.5mm.

Consult Fig. 4,8, when the bottle stopper 2 of present embodiment during in assembling, it is straight in the control hole 34 that is pressed into obturating plug 3 at first will to control seat 4, spiral shell rotary head 422 bottoms owing to control seat 4 when being pressed into are the section of having a down dip 455 that bring together the bottom, so spiral shell rotary head 422 can slightly be shored the plug wall 32 of obturating plug 3 toward radial outer end, when spiral shell rotary head 422 tops by the control hole 34 the section of bringing together 342 root edges the time, just can be positioned in the holding part 303 that size cooperates on the control hole 34, this moment, 2 of bottle stoppers were at a unswollen state, and the plug wall 32 that so-called herein unswollen state is meant obturating plug 3 is by outside top, spiral shell rotary head 422 footpaths.Under this state, bottle stopper 2 can be fitted into bottleneck 20.

Consult Fig. 5,9, when bottle stopper 2 of the present invention will be transformed into the swelling state of Fig. 9 by the unswollen state of Fig. 8, the user clockwise rotates this control seat 4 in spiral shell commentaries on classics mode, because the guide screw guide channel 302 in control hole 34 is to be extended toward bulge 304 one by holding part 303, therefore the action of this spiral shell commentaries on classics, can allow the spiral shell rotary head 422 of control seat 4 move down into bulge 304 by holding part 343, because the imaginary aperture D21 of this bulge 304, D22 is respectively 10.5mm, 11.5mm, and maximum dimension D 5 is 12mm in this spiral shell rotary head 422, therefore when spiral shell rotary head 422 spiral shells forward bulge 304 to, the plug wall 32 that can force obturating plug 3 is slightly toward radial expansion, make the outside wall surface of obturating plug 3 abut against on the interior bottle anchor ring 201 of bottleneck 20, reach the leak free purpose whereby.And in control seat 4 processes that move down, is the position in the control hole 34 of obturating plug 3? gas can discharge by the exhaust duct 43 of control seat 4.

Identical reason, when the present invention will make bottle stopper 2 be transformed into the unswollen state of Fig. 8 by the swelling state of Fig. 9, as long as backward rotation is somebody's turn to do control seat 4, spiral shell rotary head 422 pines of control seat 4 are fallen back in the holding part 303 of size cooperation, at this time just can take out bottle stoppers 2 from bottleneck 20 easily.In design, the present invention is in order to allow the use habit that more meets common people of controlling of controlling seat 4, it is that structure with " multiple-screw thread " strengthens helical pitch, that is to say, the gradient that spiral shell of the present invention changes prominent bar 45 and spiral guide channel 302 is through well-designed, at present embodiment is five line screw threads, when user's spiral shell changes this control seat 4, when making its unswollen state be transformed into the swelling state of Fig. 9 from Fig. 8, only need to rotate 1/4 circle, each spiral shell changes the updip section 454 of prominent bar 45 will the packing bulge 304 inwall first halves, and are the taper packing, produce the function of stop location whereby.And when spiral shell rotary head 422 pines of control seat 4 fall back on holding part 303 (being exactly the state of Fig. 8), the end face 451 of each helical protrusion bar 45 can be resisted against bearing surface 343 belows of inwardly contracting toward the central authorities footpath in this spiral shell rotary head 422, and can avoid control seat 4 to break away from obturating plug 3 when spiral shell changes.

Consult Figure 10,11, the bottle stopper 2 of the present invention's second preferred embodiment also can be installed in a bottleneck 20 places, comprise: an obturating plug 3 and a control seat 4, wherein the structure of this control seat 4 is same as first embodiment and no longer illustrates, and this obturating plug 3 also comprises: diapire 31, the plug wall 32, by wall 33 and the control hole 34, wherein this control hole 34 also has: awl entrance 341, the section of bringing together 342, and the spiral shell section of leading 30, this spiral shell section of leading 30 has the holding part 303 that a size cooperates with spiral shell rotary head 422, and a undersized is in the bulge 304 of spiral shell rotary head 422.Second embodiment of the invention is with the difference of first embodiment: this spiral shell section of leading 30 has more one and is positioned at these bulge 304 bottoms and size and holding part 303 identical pines and moves back portion 305.

Cooperate Figure 12, when the bulge 304 of the spiral shell rotary head 422 corresponding status of control seat 4 in control hole 34, be subjected to shoring of this spiral shell rotary head 422, the central part of the plug wall 32 of this obturating plug 3 can produce the effect that trace and footpath are expanded, to produce the effect of driving fit, because this variation is very little not shown.And when the further spiral shell of user changes this control seat 4 pines that cause spiral shell rotary head 422 to move down into obturating plug 3 and moves back portion 305, because moving back the size and the spiral shell rotary head 422 of portion 305, pine cooperates, therefore can not shore the plug wall 32 of obturating plug 3, make this obturating plug 3 return to original position, bottle stopper 2 be pulled away bottleneck 20 with convenient.

The present invention's second preferred embodiment is to be used in to force the bottle stopper 2 can't reusable occasion, for example some drinks is that a uncork just must finish off, these are different with the reusable design of first embodiment, in order to meet human operating habit, the spiral guide channel 302 of second embodiment of the invention can adopt minus thread, moves back portion 305 tops this pine and has more one toward the interior radially outstanding non-return face 306 that supports.The mankind are to rotate bottle cap between the inverse time when wanting uncork, and according to the design of minus thread, when rotating counterclockwise the control seat 4 of present embodiment, this spiral shell rotary head 422 can be transformed into the non-expansion state of Figure 12 by the swelling state of Figure 11, and be subjected to this non-return restriction of supporting face 306, the spiral shell rotary head 422 of this control seat 4 whiz pine that can't reverse moves back portion 305, reaches bottle stopper 2 whereby and steps back the purpose that just can't return to swelling state pine.

Consult Figure 13,14, the multiple-screw thread of third embodiment of the invention also can be a quadruple thread, that is to say, helical protrusion bar 45 on this control seat 4 is four, the interventral angle [alpha] of above-mentioned helical protrusion bar 45 and spiral shell can be 45 degree, and the spiral guide channel also is corresponding design, makes things convenient for the demoulding when molded and shaped whereby.

In addition, subsidiary supplemental instruction be, in above each embodiment, this obturating plug 3 or control seat 4 also can be divided into two earlier to be made respectively, with convenient in the demoulding when molded and shaped, and after molded and shaped again with laser light or ultrasonic with two agllutination integrators.

By above explanation as can be known, the technology that the present invention utilizes spiral shell to change, make control seat 4 after the suitable angle of rotation, 1/4 when circle for example, the spiral shell rotary head 422 of this control seat 4 is able to move axially by the control hole 34 interior spiral guide channels 302 of obturating plug 3 design of one section helical pitch, not only do not see bottle stopper in the past, this design has more following effect:

One, few, the simple structure of part: bottle stopper of the present invention only comprises an obturating plug 3 that is enclosed within on the bottleneck 20 in design, and one force the control seat 4 of the part paragraph dilatational strain of obturating plug 3 in spiral shell commentaries on classics mode, certain three assemblies of bottle stopper more in the past of the design of above-mentioned pair of assembly are simplified, 3 of control seat 4 simultaneously of the present invention and obturating plugs also can produce guiding and locating effect by the path length of spiral lamination and the change of multistage awl, need not to set up again other location design, so also the person was simple for structure of the present invention more in the past.

Two, operational sign is closed common people's use habit: the present invention forces control seat 4 to move axially one section helical pitch in the mode that spiral shell changes, and the mode that above-mentioned spiral shell changes is more in the past directly laborsaving to pushing not only, also uses the custom of article to meet with common people.Control simultaneously, also can improve misoperation and cause bottle stopper 2 to be transformed into non-expansion state, cause sealing effectiveness to lose efficacy by swelling state in spiral shell commentaries on classics mode.
